Lake Shore Gold and the Qualified Persons who authored this report undertake no obligation to update publicly or otherwise revise any forward-looking statements whether as a result of new information or future events or otherwise, except as may be required by law.

CAUTIONARY NOTE TO U.S. READERS CONCERNING ESTIMATES OF MEASURED, INDICATED AND INFERRED MINERAL RESOURCES

Information concerning the Bell Creek Mine has been prepared in accordance with Canadian standards under applicable Canadian securities laws, and may not be comparable to similar information for United States companies. The terms “Mineral Resource”, “Measured Mineral Resource”, “Indicated Mineral Resource” and “Inferred Mineral Resource” used in this report are Canadian mining terms as defined in accordance with National Instrument 43-101 (“NI 43-101”) under guidelines set out in the Canadian Institute of Mining, Metallurgy and Petroleum (“CIM”) Standards on Mineral Resources and Mineral Reserves adopted by the CIM Council on November 27, 2010. While the terms “Mineral Resource”, “Measured Mineral Resource”, “Indicated Mineral Resource” and “Inferred Mineral Resource” are recognized and required by Canadian securities regulations, they are not defined terms under the rules and regulations of the United States Securities and Exchange Commission applicable to mining companies. As such, certain information contained in this report concerning descriptions of mineralization and resources under Canadian standards is not comparable to similar information made public by United States companies subject to the reporting and disclosure requirements of the United States Securities and Exchange Commission. An “Inferred Mineral Resource” has a great amount of uncertainty as to its existence and as to its feasibility. It cannot be assumed that all or any part of an “Inferred Mineral Resource” will ever be upgraded to a higher category. Readers are cautioned not to assume that all or any part of an “Inferred Mineral Resource” exists, or is mineable.

1.0SUMMARY

This Bell Creek Mine Technical Report has been prepared under the supervision of Eric Kallio (P. Geo.) and Natasha Vaz (P. Eng, MBA) on behalf of Lake Shore Gold Corp. (LSG) for the Bell Creek Mine and conforms to NI 43-101 Standards of Disclosure for Mineral Projects. These individuals are considered Qualified Persons (QPs) under 43-101 definitions.

The purpose of this technical report is to provide an update of the total estimated resource pool, current mine infrastructure, the life-of-mine plan, and estimated capital and operating costs to substantiate an updated Mineral Reserve estimate for Bell Creek Mine for the measured and indicated resource subset between the 445 metre elevation (445L) and 1165L.

The revised mineral resource estimate uses exploration data collected by LSG from underground and surface drilling completed since the previous resource report submitted to SEDAR titled “NI 43-101 Technical Report, Resource Estimate Update and Prefeasibility Study and Mineral Reserve Estimate for Bell Creek Mine, Hoyle Township, Timmins, Ontario, Canada March 28, 2013, having an effective date of November 1, 2012” and is prepared in accordance with National Instrument 43-101, Standards and Disclosure for Mineral Projects. The effective date of this report is December 31, 2014.

The Bell Creek Mine is located in the Porcupine Mining Division, Hoyle Township, approximately 20 kilometres (km), by road, northeast of Timmins, Ontario. Access to the property is via Florence Street, a 6.7 km all-season asphalt and gravel road north from the community of Porcupine, off of Ontario Provincial Highway 101.

The Bell Creek Mine Property is made up of the Bell Creek claims, the adjacent Schumacher claim and two “northern claims” totaling 12 leases and five patented Boer War Vet lots. These claims cover a total area of approximately 512 hectares (ha), 320 ha in the Bell Creek claims, 64 ha in the Schumacher claim and 128 ha in the two “northern claims”. LSG owns 100% interest in the Property subject to underlying royalties. The claims are all in good standing.

Gold mineralization was first discovered on the property through a joint venture between Rosario Resources Canada Ltd. (Rosario) and Dupont of Canada Exploration Limited (Dupont) between 1980 and 1982. Between 1986 and 1991 Canamax Resources Inc. (Canamax) explored and developed the Bell Creek Mine. Access to mineralization was through a 290 metre deep shaft. Mine levels were developed to the ore zones, and an internal ramp was developed from the 240 metre level to access ore below shaft bottom to a vertical depth of 300 metres. Falconbridge Gold Corporation (Falconbridge) operated Bell Creek Mine from 1991 to 1992 followed by Kinross Gold Corporation (Kinross) until mine closure in 1994.

Total production during the period prior to the 1994 mine closure totaled 576,017 tons of ore resulting in 112,739 ounces of gold (0.196 ounces per ton or approximately 5.6 grams per tonne). The historical milling recovery was approximately 93 percent.

In January 2007, LSG entered into an agreement with Porcupine Joint Venture (PJV) to acquire the Bell Creek Mine and Mill. The Bell Creek Mine included the shaft, hoist, headframe, ore bin, collar house, hoist building, mine dry, office complex, underground mine workings and historic (non-NI 43-101 compliant) mineral resources.

Portal construction for an advanced exploration ramp began in May 2009. The ramp provided access to historic mine workings, and provided platforms for exploration diamond drilling. A number of sublevels were established at 15 metre vertical intervals below the 300 metre level and a bulk sample taken.

The Bell Creek Mine declared commercial production effective January 1, 2012.

The Bell Creek Mine property is underlain by carbonate altered, greenschist facies Archean-aged, metavolcanic and clastic metasedimentary rocks belonging to the Tisdale and Porcupine assemblages. The strike of these rocks is generally east-west to west-northwest, with steep southerly dips.

Gold mineralization in the Bell Creek Mine occurs in steep south dipping, sheet like, shear hosted mineralized zones. A series of 16 mineralized zones (14 sub-parallel and two splay zones) have been identified. Of these, the bulk of the mineralization occurs within the North A, North A2, North B and North B2 zones. The North A zone has dominantly been the source of historical production. Mineralization and the geological setting of these zones are similar.

The North A Zone outcrops approximately 200 metres north of the Bell Creek headframe and consists of a marker quartz vein that varies from 0.1 metres to 2 metres in width with an associated alteration halo. Adjacent to the quartz marker vein is a grey to buff coloured altered zone which contains 5 to 15% pyrite and pyrrhotite, with accessory chalcopyrite and arsenopyrite. Up to 30% of the gold in the North A Zone occurs within the alteration halo, in discrete sulphide zones and in vein-brecciated wall rock zones that extend up to five metres from the margin of the core vein (Kent, 1990).

The Mineralized domains used to estimate resources have been modeled on vertical north-south sections on 6.25, 12.5 and 25 metre centres, with consideration for structural setting and lithology. Section spacing was reduced in areas of greater drill density. Underground development was used as an aid in the interpretation and design of the mineralized zones.

The sectional interpretations were used to create three-dimensional (3D) solids or wireframes representing the mineralized zones that are used for estimation of tonnes and grade. A total of 16 mineralized domain solids were created.

The Mineral Resource estimate for the Bell Creek Mine is based on diamond drill assays composited to 1.0 metre lengths. Only intersections within each vein solid were used to estimate grades. A total of 938 drill holes were used in the estimate including 119 historic surface and underground holes, and 819 surface and underground drill holes completed by LSG. Development chip or muck sample assay data was not used in the estimate.

The resource totals 4.90 Mt at 4.36 g/t Au amounting to 686,700 ounces of gold in the Measured and Indicated category and 4.40 Mt at 4.84 g/t Au amounting to 685,000 ounces of gold in the Inferred category. The resource was estimated using Inverse Distance to the power 2 (ID2) interpolation method with gold assays capped to 44 g/t for the North A vein, and 34 g/t for all other domains excepting the Hangingwall veins which were capped to 25 g/t. An assumed long-term gold price of US$1,100 per ounce and 0.90 $US/$CAD exchange rate were used. The base case estimate assumes a cut-off grade of 2.2 g/t Au with no allowance for dilution. The total estimated resources for Bell Creek Mine are summarized in Table 1.1.

Notes:

1.The effective date of this report is December 31, 2014.

2.The mineral resource estimates have been classified according to CIM Definitions and Guidelines.

3.Mineral resources are reported inclusive of reserves.

4.Mineral resources incorporate a minimum cut-off grade of 2.2 grams per tonne for the Bell Creek Mine which includes dilution to maintain zone continuity.

5.Cut-off grade is determined using a weighted average gold price of US$1,100 per ounce and an exchange rate of 0.90 $US/$CAD.

6.Cut-off grade assumes mining and G&A costs of up to $77 per tonne and/or processing costs of $22 per tonne and assumed metallurgical recovery of 94.5%.

7.Mineral resources have been estimated using the Inverse Distance Squared estimation method and gold grades which have been capped between 25 and 44 grams per tonne based on statistical analysis of data in each zone.

8.Assumed minimum mining width is two metres.

9.The mineral resources were prepared under the supervision of, and verified by, Eric Kallio, P. Geo., Senior Vice-President, Exploration, Lake Shore Gold Corp., who is a qualified person under NI 43-101 and an employee of LSG.

10.Tonnes information is rounded to the nearest thousand and gold ounces to the nearest one hundred, as a result totals may not add exactly due to rounding.

A sensitivity analysis was carried out to examine the impact on the tonnage, grade, and contained ounces by increasing the cut-off grade. The results are presented graphically in Figure 1.1. It should be noted that this is only a graphical presentation of potential opportunities to optimize the resource.

Recommendations consist primarily of diamond drilling which would continue to test the Bell Creek deposit as well as testing “regional” targets on the Bell Creek property. The objective of the deposit drilling would be to target sufficient resource conversion (indicated to measured and inferred to indicated) in order to complete a robust mining plan. The first phase of the deposit drilling (8,300m) would be completed from the 610L drill drift, while phases two (10,300m) and three (19,000m) would be completed from a recommended drill platform on the 760L. Phase One drilling is estimated at an all-in cost of $745,000 while Phases Two and Three would cost $1.0 million and $1.9 million respectively. The proposed 760L drill platform would be developed in two stages, estimated to cost $1.1 million and $1.5 million respectively.

The regional drilling would test known gold showings such as Bell Creek West of Dyke, Wetmore, Stringer and Marlhill East and West as well as favourable stratigraphy with holes from both underground and surface. This regional program is envisioned to consist of 15,000 metres of drilling at an all-in cost of $1.5 million.

The cost to finalize and implement a production reconciliation program, which will aid in improving resource estimation and mine planning, is $10,000.

It is recommended that the Phase One drilling and Stage One development be completed in 2015 while Phases Two and Three drilling and Stage Two development be completed in 2016. The total cost of all recommended programs, finalizing the reconciliation process, completing the regional and deposit drilling, and development of the 760L drill platform is estimated to be $7.76 million.

The subset of the total Bell Creek Mine resource pool considered in this report includes the measured and indicated resource material located between the 445L and 1165L.

A mine design was completed on this measured and indicated resource to estimate the proven and probable reserves. The mine design used for the updated reserves estimate has been based on existing surface and underground infrastructure and operating experience. The majority of the main mine infrastructure (surface and underground) is in place, most equipment has been purchased, and the Bell Creek Mill is capable of meeting production requirements. Bell Creek Mine successfully uses the narrow longitudinal longhole mining method which is commonly used for deposits with similar geometry and conditions. The operation also uses common, proven mining equipment and has experienced management and mine operations personnel. The Timmins area has a significant, well-established mining service/supply industry to support the operation. Through operating experience, the operation has implemented the systems and programs (i.e. health and safety, environment, training, maintenance, operating procedures, etc.) necessary to sustain production. This experience has also provided a solid basis for estimating the capital and operating costs used in preparation of the life of mine (LOM) plan.

Mining shapes (stope wireframes) were designed in three dimensions for all measured and indicated resources included in the mining plan and the in-situ resource within the stope wireframes (including any low grade or barren material) was extracted from block model data. External dilution was estimated for each stope based on stope geometry and a 95% mining recovery factor was applied to account for unplanned losses. Stope cut-off grades were estimated to determine which stopes to include in the reserves. Detailed mine development layouts and construction activities were assigned to provide access to each of the stoping units. A detailed LOM development and production schedule was prepared to estimate the annual tonnes, average grade, and ounces mined to surface. Development, construction, and production costs were estimated to allow an economic assessment to be made comparing the capital and operating expenses required for each area to the expected revenue stream to ensure economic viability. The estimated proven and probable reserves are summarized in Table 1.2.

Table 1.2:Bell Creek Mine Estimated Reserves

	Diluted/Recovered		Ounces Mined
Reserve Classification	Tonnes	Grade	To Surface
Proven	172,228	4.5	24,857
Probable	1,620,067	4.6	238,751
Total (Proven + Probable)	1,792,295	4.6	263,608

Notes:

1.The effective date is of this report is December 31, 2014.

2.The mineral reserve estimates are classified in accordance with the Canadian Institute of Mining Metallurgy and Petroleum’s “CIM Standards on Mineral Resources and Reserves, Definition and Guidelines” as per Canadian Securities Administrator’s National Instrument 43-101 requirements.

3.Mineral reserves are based on a long-term gold price of US$1,100 per ounce and an exchange rate of 0.90 $US/$CAD.

4.Mineral reserves are supported by a mine plan that features variable stope thicknesses, depending on zone, and expected cost levels, depending on the mining methods utilized.

5.Mineral reserves incorporate a minimum cut-off grade of 2.7 grams per tonne. The cut-off grade includes estimated mining and site G&A costs of $77 per tonne, milling costs of $22 per tonne, mining recovery of 95.0%, external dilution of 13% and a metallurgical recovery rate of 94.5%.

6.The mineral reserves were prepared under the supervision of, and verified by, Natasha Vaz, P. Eng., Vice-President, Technical Services, Lake Shore Gold Corp., who is a qualified person under NI 43-101 and an employee of Lake Shore Gold.

Note: The reserves LOM production profile does not necessarily reflect company guidance.

Annual ounce production is presented as a range (upper and lower). The range is based on ±10% variance from the LOM plan to reflect potential differences in the combination of stopes that may be mined during each year.

The estimated capital and operating costs have been based on operating experience at the Bell Creek Mine and the Bell Creek Mill. The estimated LOM capital and operating costs are summarized in Table 1.4.

Table 1.4:Estimated LOM Capital and Operating Costs

	Total Costs
Cost Item	(millions)		Cost per Tonne
Capital Cost	$	62.6	$	34.9/tonne
Operating Cost	$	179.8	$	100.3/tonne

The costs and productivities used as the basis for estimating the reserves have been based on actual performance metrics of the operation in 2012 through 2014. These factors are considered low risk to the reserve estimate. In addition, social, political, and environmental factors are all considered to be low risk factors for the continued operation of Bell Creek Mine and to the reserves estimate.

2.4DEFINITIONS

The following definitions of Mineral Resources and Mineral Reserves have been prepared by the CIM Standing Committee on Reserve Definitions and adopted by the CIM Council on November 27, 2010.

2.4.1Mineral Resource

Mineral Resources are sub-divided, in order of increasing geological confidence, into Inferred, Indicated, and Measured categories. An Inferred Mineral Resource has a lower level of confidence than that applied to an Indicated Mineral Resource, which has a lower level of confidence than a Measured Mineral Resource.

A “Mineral Resource” is a concentration or occurrence of diamonds, natural solid inorganic material, or natural solid fossilized organic material including base and precious metals, coal, and industrial minerals in or on the Earth’s crust in such form and quantity and of such a grade or quality that it has a reasonable prospect for economic extraction. The location, quantity, grade, geological characteristics, and continuity of a Mineral Resource are known, estimated, or interpreted from specific geological evidence and knowledge.

2.4.2Inferred Mineral Resource

An “Inferred Mineral Resource” is that part of a Mineral Resource for which quantity and grade or quality can be estimated on the basis of geological evidence and limited sampling and reasonably assumed, but not verified geological and grade continuity. The estimate is based on limited information and sampling gathering through appropriate techniques from locations such as outcrops, trenches, pits, workings, and drill holes.

2.4.3Indicated Mineral Resource

An “Indicated Mineral Resource” is the part of the Mineral Resource for which quantity, grade or quality, densities, shape and physical characteristics can be estimated with a level of confidence sufficient to allow the appropriate application of technical and economic parameters, to support mine planning and evaluation of the economic viability of the deposit. The estimate is based on detailed and reliable exploration and testing information gathered through appropriate techniques from locations such as outcrops, trenches, pits, workings, and drill holes that are spaced closely enough for geological and grade continuity to be reasonably assumed.

2.4.4Measured Mineral Resource

A “Measured Mineral Resource” is the part of the Mineral Resource for which quantity, grade or quality, densities, shape and physical characteristics are so well established that they can be estimated with confidence sufficient to allow the appropriate applications of technical and economic parameters, to support production planning and evaluation for the economic viability of the deposit. The estimate is based on detailed and reliable exploration, sampling and testing information gathered through appropriate techniques from locations such as outcrops, trenches, pits workings and drill holes that are spaced closely enough to confirm both geological and grade continuity.

Technical Report, Bell Creek Mine, 27 March 2015

11

2.4.5Mineral Reserve

Mineral Reserves are sub-divided in order of increasing confidence into Probable Mineral Reserves and Proven Mineral Reserves. A Probable Mineral Reserve has a lower level of confidence than a Proven Mineral Reserve.

A Mineral Reserve is the economically mineable part of the Measured or Indicated Mineral Resource demonstrated by at least a Preliminary Feasibility Study. This Study must include adequate information on mining, processing, metallurgical, economic, and other relevant factors that demonstrate, at the time of reporting, that economic extraction can be justified. A Mineral Reserve includes diluting minerals and allowances for losses that may occur when the material is mined.

2.4.6Probable Mineral Reserve

A “Probable Mineral Reserve” is the economically mineable part of an Indicated and, in some circumstances, a Measured Mineral Resource demonstrated by at least a Preliminary Feasibility Study. This Study must include adequate information on mining, processing metallurgical, economic, and other relevant factors that demonstrate, at the time of reporting that economic extraction can be justified.

2.4.7Proven Mineral Reserve

A “Proven Mineral Reserve” is the economically mineable part of a Measured Mineral Resource demonstrated by at least a Preliminary Feasibility Study. This Study must include adequate information on mining, processing, metallurgical, economic, and other relevant factors that demonstrate, at the time of reporting, the economic extraction is justified.

4.0PROPERTY DESCRIPTION AND LOCATION

4.1PROPERTY DESCRIPTION

The Bell Creek Mine Property is made up of the Bell Creek claims, the adjacent Schumacher claim and two “northern claims” totaling 12 leases and five patented Boer War Vet lots. The Bell Creek claims consist of 12 leased and two patent Boer War “Vet” lots covering a total area of approximately 320 ha, the Schumacher property and the two northern claims are also Boer War “Vet” lots each covering an area of approximately 64 ha. To maintain these claims in good standing, yearly Lease Rents (MNDM) and Land Tenant Taxes (MNR) are required to be paid for the leased claims, while Land Taxes (MNDM) and municipal taxes are required for the “Vet” lots. Of the 12 leased claims, eight are due for renewal on September 30, 2025 with the remaining four due for renewal on September 30, 2027. Refer to Table 4.1 for a more complete description of these properties.

Bell Creek Mine was operated by Canamax between 1989 and 1991. Falconbridge operated the mine between 1991 and 1992, followed by Kinross in 1993 and 1994 when mining operations ceased. The mine was kept on care and maintenance until 2001, when a decision was made to allow the underground workings to flood. In 2002, the Porcupine Joint Venture (PJV), a joint venture between Placer Dome Canada Ltd. (Placer) and Kinross, was formed and in 2005 the property was reactivated. Goldcorp Inc. (Goldcorp) acquired Placer’s interest later that year and became the operator of the PJV (Butler, 2008). Acquisition of the property by Lake Shore Gold (LSG) was finalized on December 18, 2007.

Within the property limits are the Bell Creek Deposit as well as mine infrastructure including shaft, ramp, Bell Creek Mill, tailing facilities as well as office, warehouse, and dry facilities.

4.2LOCATION

The Bell Creek property is located in Hoyle Township, Porcupine Mining Division, approximately 20 km by road, northeast of Timmins, Ontario (Figure 4.1). Access to the property is gained via Florence Street, a 6.7 km long all-weather asphalt and gravel road north of Ontario Provincial Highway 101. The project is situated approximately 564 km north-northwest of Toronto, Ontario. The mine infrastructure is located within National Topography Series Map reference 42-A-11 southeast, at longitude 81° 10’ 41” west and latitude 48° 33’ 45” north.

4.3RECENT OWNERSHIP HISTORY AND UNDERLYING AGREEMENTS

4.3.1Schumacher Property

In November 2005, LSG signed a 20-year lease agreement giving it a leasehold interest in the surface and mining rights on the Schumacher property. The lease is renewable for another 20-year term. The property is a Boer War Vet Lot and, as such, is a freehold patent with both surface and mining rights (granted by the Crown before May 6, 1913). There is no requirement to file assessment reports with the Ministry of Northern Development and Mines (MNDM). As the property is a Boer War “Vet” Lot in a surveyed township, its boundaries are fixed for an area of approximately 64 ha. It is bounded to the west by Bell Creek and the east by the Vogel property. LSG is required to make an annual advanced royalty payment of C$25,000 in years four to six of the lease and C$50,000 thereafter (indexed to inflation) and to pay a 2% NSR once commercial production begins (internal company documents).

4.3.2Bell Creek Claims

On January 31, 2007, LSG announced that the company had entered into a binding letter of agreement with Goldcorp, manager of the PJV, to acquire the Bell Creek Mine. In March 2007, the two companies agreed to amend their binding letter of agreement to extend the due diligence period and the acquisition was finalized on December 18, 2007. Consideration for the acquisition consisted of C$7.5 M in cash and C$2.5 M worth of LSG shares at a price of $1.51 per share (1,655,629 shares) as well as two million warrants exercisable for a period of two years at C$2.41 per share.

The agreement is subject to a 2% Net Smelter Return (NSR) royalty payable to the PJV comprised of Goldcorp and Kinross. Kinross has subsequently assigned its rights under the agreement to Goldcorp. Underlying royalty agreements affect some of the Bell Creek claims including two agreements with net profit interests that can be purchased outright for relatively small amounts.

4.3.3Northern Claims

The two “northern claims” were acquired from Goldcorp in 2009 as part of the “Bell Creek West” acquisition (LSG press release, December 17, 2009). These claims are both Boer War Vet lots, located in a surveyed township and as such have fixed boundaries for an area of approximately 64 ha. These claims are subject to various royalties.

A summary of the land tenure is provided in Table 4.1 and Figure 4.2, which shows the mining rights disposition.

4.4PAST MINING ACTIVITY, ENVIRONMENTAL LIABILITIES AND PERMITTING

Gold mineralization was first discovered on the Bell Creek Mine property through a joint venture between Rosario and Dupont between 1980 and 1982. Between 1986 and 1991 Canamax explored and developed the Bell Creek Mine. Access to mineralization was through a 290 metre deep three compartment shaft with an 8-foot diameter double drum hoist, and includes a 30 metre high headframe with a 300 tonne coarse ore bin to a loadout facility. Mine levels were developed to the ore zones, and a ramp was developed from the 240 metre level to access ore below shaft bottom to a vertical depth of 300 metres. A 300 tonne per day (tpd) mill was commissioned in 1987.

From 1991 to 1992 Falconbridge Gold operated Bell Creek Mine followed by Kinross until the mine’s closure in 1994. The mine was kept on care and maintenance until 2001 when it was allowed to flood.

Bell Creek produced at a rate of 380 tpd and was reported to have produced 576,000 short tons of ore at a grade of 0.197 oz/ton (5.57 g/t) Au using vertical sublevel retreat, longhole, and shrinkage mining methods. This includes some ore from Marlhill.

On January 1, 2012 LSG announced the Bell Creek Mine to be in commercial production.

The tailings treatment facilities are managed by LSG staff with regularly scheduled inspections conducted by AMEC. In 2014 the tailings facility was expanded to include an additional 2 million tonnes of storage capacity.

A closure plan amendment was submitted in July of 2012 to combine the Mine and Mill assets into one closure plan which was filed in March of 2014. An additional Closure Plan Amendment is currently being prepared to include the tailings expansion for the Bell Creek Tailings Facility.

From the Ministry of Natural Resources’ Species at Risk in Ontario (“SARO”) list, the species that may range within the Bell Creek Mine area are summarized in Table 4.2.

5.4PHYSIOGRAPHY

Bell Creek exhibits low to moderate topographic relief, with the property elevation ranging from 285 to 298 metres above sea level. Drainage is characterized by slow, meandering creeks and rivers that flow into the Arctic watershed as shown in Figure 5.1. Bell Creek, which lends its name to the deposit, flows across the property and into the Porcupine River in a north-northwest direction. Outcrop exposure is less than three percent.

The Timmins area is situated in plant hardiness zone 2a, which supports boreal forest tree species and an active timber, pulp, and paper industry. Local trees species include: American Mountain-Ash, Balsam Fir, Black Spruce, Eastern White Cedar, Eastern White Pine, Jack Pine, Pin Cherry, Red Pine, Tamarack, Trembling Aspen, White Birch, White Spruce, and Speckled Alder.

Timber was harvested from the Schumacher property in 1997. A small stand of trees was removed from west of the Bell Creek headframe in 2009.

6.0HISTORY

6.1PRIOR OWNERSHIP

In November 2005, Lake Shore Gold (LSG) signed a 20-year lease agreement securing a leasehold interest in the surface and mining rights on the Schumacher property. The lease is renewable for an additional 20-year term. Acquisition of the Bell Creek claims by LSG from the previous owner, PJV, was finalized on December 18, 2007. The two “northern claims” were acquired by LSG from the previous owner in December 2009

Underlying royalties are applicable to these acquisitions and have been summarized in Item 4.3.

6.2GENERAL HISTORY

The discovery of gold occurrences in the Timmins area began to appear in historic records in the early part of the twentieth century. The extension of the railway lines from Cobalt, Ontario, in the early 1900s allowed for new access to the gold discoveries found near Porcupine and Nighthawk Lakes. With increased access to the region, numerous gold discoveries were reported that initiated the rush to the Porcupine Gold Camp. World class gold deposits were found in the area, with 1909 being of particular note with the discovery of the Vipond, Dome, and Hollinger Mines.

Few bedrock outcrops in the Bell Creek area and the clay-rich nature of the surface cover restricted prospectors’ ability to find alluvial gold trains in creek bottoms and trace them back to the source material (the main exploration method employed at the time). With the advent of airborne geophysics in the 1960s, the first discoveries were made below the clay-rich belt that surrounds Timmins. Prior to that, gold was found either in outcrop directly or along the strike of outcrops. Gold mineralization found below this “clay-belt” occurred in what is now southern Hoyle Township (Butler, 2008).

Prior to the 1960s, little geological work is found in the public domain for the Bell Creek area. Work completed by the Ontario Geological Survey (OGS) and Ontario Department of Mines for the Hoyle Township area is summarized in Table 6.1.

Gold mineralization was first discovered on the Bell Creek property through a joint venture between Rosario and Dupont between 1980 and 1982. Between 1986 and 1991, Canamax explored and developed the Bell Creek Mine. Access to mineralization was through a 290 metre deep, three compartment shaft with an 8-foot diameter double drum hoist, and included a 30-metre high headframe with a 300 tonne coarse ore bin to a loadout facility. Mine levels were developed to the ore zones, and a ramp was developed from the 240 metre level to access ore below shaft bottom to a vertical depth of 300 metres. A 300 tpd mill was commissioned in 1987.

From 1991 to 1992 Falconbridge operated Bell Creek Mine followed by Kinross until the mine’s closure in 1994. The mine was kept on care and maintenance until 2001 when it was allowed to flood.

Bell Creek produced at a rate of 380 tpd and was reported to have produced 576,000 short tons of ore at a grade of 0.197 oz/ton (5.57 g/t) Au using vertical sublevel retreat, longhole, and shrinkage mining methods. This includes some ore from Marlhill. The bulk of the production was derived from the North A Zone where mining occurred on multiple levels (Butler, 2008).

Canamax held the Schumacher property under option during the period 1984 to 1985 and conducted a three hole drill program (core diameter unknown) that encountered minor low grade gold-bearing veins that did not exceed 0.31 g/t Au over 1.0 metre.

In the period 1986 to 1990, Falconbridge Gold completed geophysical surveys and drilled 24 diamond drill holes (diameter unknown) that encountered sporadic alteration and mineralization. Small, anomalous intersections of 25.5 g/t Au over 0.5 metres and 13.34 g/t Au over 0.25 metres were reported.

In 1995, Pentland Firth Ventures Ltd. (PFV) entered into a mining lease agreement, established an exploration grid, and conducted an undisclosed amount of ground geophysical surveys. In 1996, PFV cored 25 drill holes (diameter unknown) encountering 4.40 g/t Au over 5.1 metres (including 34.19 g/t Au over 0.4 metres) and 3.28 g/t Au over 7.3 metres. In 1997, PFV drilled an additional five holes that were used in a property valuation report prepared by RPA. At the time, the property was valued at $2.3 million.

Exploration work completed by operators prior to LSG is summarized in Table 6.2.

6.3HISTORICAL RESOURCE ESTIMATES

6.3.1Historically Significant Non-Compliant NI 43-101 Resource Estimates

The following mineralization estimates are not compliant with NI 43-101 but are considered historically significant in keeping exploration interest active at the Bell Creek Mine. These estimates have not been validated, are not considered to be current, and are quoted from the documents referenced.

In 1996, PFV commissioned an independent consultant, Unto Jarvi, to produce a resource estimate based on available drill information.

Technical Report, Bell Creek Mine, 27 March 2015

28

In 1997, Crick reported a “drill-indicated” resource based on the additional drilling done by PFV. This resource, with approximately half of the mineralization occurring above the 125L hosted in stacked flat vein sets, also predates NI 43-101 and is quoted for historic purposes only (Butler, 2008).

Table 6.3:Historic Resource Estimate for the Bell Creek Deposit

Year	Classification	Tonnes	Grade Au (g/t)
19961	Undefined	156,117	5.99
19972	“Drill-indicated”	673,425	2.89

Notes:

1.Employed a cut-off grade of 3 g/t Au, a 200 g/t Au top cut.

2.Employed a cut-off grade of 3 g/t Au, a 34.29 g/t Au top cut, a minimum 1.5 metre width, and allowing for a 15 metre crown pillar.

A Mineral Resource estimate was completed by the PJV in 2004 using a polygonal model and a gold price of US$425 per ounce. This model was updated in 2005 to a computer generated block model that yielded similar grades but was reclassified by PJV as a “Mineral Inventory”. The 2004 estimate is derived from Butler (2008) and summarized in Table 6.4.

Between 1986 and 1991 Canamax Resources Inc. explored and developed the Bell Creek Mine. Access to mineralization was through a 290 metre deep, three compartment shaft with an 8-foot diameter double drum hoist, and included a 30-metre high headframe with a 300 tonne coarse ore bin to a loadout facility. Mine levels were developed to the ore zones, and a ramp was developed from the 240 metre level to access ore below shaft bottom to a vertical depth of 300 metres. Falconbridge Gold operated Bell Creek from 1991 to 1992, followed by Kinross until closure in 1994. The mine was kept on care and maintenance until 2001 when it was allowed to flood.

Bell Creek produced at a rate of 380 tpd and was reported to have produced 576,000 short tons of ore at a grade of 0.197 oz/ton (6.13 g/t) Au using vertical sublevel retreat, longhole, and shrinkage mining methods. This includes some ore from Marlhill. The bulk of the production was derived from the North A Zone where mining occurred on multiple levels (Butler, 2008). Table 6.6, from Pressacco (1999), summarizes historical ore production from Bell Creek.

7.0GEOLOGICAL SETTING AND MINERALIZATION

7.1REGIONAL GEOLOGY AND STRUCTURE

The Bell Creek deposit is located in the western part of the Archean aged Southern Abitibi Greenstone Belt, a supracrustal complex of moderately to highly deformed, usually greenschist facies, volcanic-dominated oceanic assemblages that are approximately 2.7 million years in age. Supracrustal rocks in the Timmins region are assigned as members of seven volcanic and two sedimentary assemblages within the Western Abitibi Subprovince of the Superior Province. Intrusions were emplaced during the Archean and Proterozoic eons.

Keewatin Series greenstone volcanics are found in spatially discrete groupings and contain tholeiitic volcanic lineages as well as other volcanic assemblages that were tectonically combined with spatially discrete komatiite-rich assemblages, banded iron formations, and turbidite-bearing sedimentary basins. Unconformably overlying the Keewatin Series are younger sub-aqueous to sub-aerial volcanic-sedimentary rocks of the Timiskaming Series. These rocks occur along the margins of late regional tectonic deformation zones that are near strike-parallel shears and/or faults which commonly show high strain and tight, vertically verging folding.

Batholiths and stocks found in the Southern Abitibi are approximately sequential from tonalite-monzonite-granodiorite through massive granodiorite, granite, feldspar ±quartz porphyry to syenite.

Approximately one century of geological study has occurred in the Timmins area. A brief, and by no means exhaustive, summary of milestones over that period is presented below and is mostly taken from Powers, 2009.

In 1896, Burwash assigned Precambrian volcanic and sedimentary rocks in the Porcupine camp to the Huronian period of the Paleo-Proterozoic era.

Between 1911 and 1925, Burrows produced the first geological map and developed a nomenclature consistent with the relationships observed by earlier workers in the Lake Timiskaming area. He made key observations regarding the spatial and temporal relationships between the Timiskaming metasediments and Keewatin Series volcanic rocks, identified the intrusive phases as post-Timiskaming in age (2.7 Ma to 2.5 Ma), and defined the relationship between the Keweenawan diabase dykes and the Matachewan quartz diabase dykes.

In 1933, Graton et al. proposed the subdivision of Keewatin volcanics in Tisdale Township. From oldest to youngest, the rocks were subdivided into the Northern, McIntyre, Central, Vipond, and Gold Centre series. The term “99 Flow” was applied to the massive flow at the base of the Vipond.

In work done in 1936 and 1939, Hurst notes that metasedimentary rocks in the Timmins area both overlie and underlie an angular unconformity. He assigned the rocks above the unconformity to the Timiskaming Series and those below the unconformity to the Keewatin Series. He interpreted the porphyries as subvolcanic stocks, emplaced into volcanic vents, and the source of the felsic volcaniclastic extrusives. Later, in 1944, Holmes interpreted the porphyries to post-date Keewatin volcanics and Timiskaming metasediments.

In 1948, Jones presented a more detailed classification scheme modeled after Graton et al. (1933) and based on his work at the Hollinger Mine. Jones introduced alphanumeric classification (e.g., V8E), gave formation status to the Northern, Central, and Vipond Series, assigned the McIntyre Series to the base of the Central Series, and renamed it the 95 Flow. That same year, Dunbar defined two groups of Keewatin volcanic rocks and named them Deloro Group and Tisdale Group. Dunbar also discriminated the Krist Formation from the underlying Tisdale Group and placed it in the Hoyle Series. Also in 1948, Buffam, adapted Jones’ Hollinger Mine terminology to the Moneta Mine, added the term “Krist Fragmental”, and described the unconformity at the base of the Krist Formation that separates it from the underlying Tisdale Group mafic volcanic flows.

In 1954, Moore included the Krist Formation with the Timiskaming Group. Following the original interpretation by Burrows in 1911, Moore placed the unconformity between Keewatin and Timiskaming rocks at the base of the Krist Formation. Also in 1954, Fuse applied Jones’ Tisdale Group nomenclature to rocks exposed at the McIntyre Mine. This was followed, in 1960, by Griffis establishing a more detailed subdivision of Tisdale Group rocks at the same deposit.

Ferguson et al. attempted to correlate the Timmins area stratigraphy in 1968, assigning Krist Fragmental to the uppermost formation in the Tisdale Group.

In 1974, using Jensen Cation Plots, Pyke subdivides the Deloro and Tisdale Groups into six formations based upon major oxide geochemical classification. The Deloro Group (Formations I through III) is a predominantly calc-alkaline sequence approximately 4,500 metres to 5,000 metres in thickness comprised mainly of andesite and basaltic flows at its base, dacitic flows and rhyolitic pyroclastics above, and, commonly, iron formation at or near the top. Most of the Deloro Group is confined to a large, centrally located domal structure. The beginning of the 4,000 metres thick Tisdale Group (Formations IV through VI) is marked by a major change in volcanism. At its base, the Tisdale Group is predominantly composed of ultramafic rocks and basaltic komatiites that are overlain by a thick sequence of tholeiitic basalt flows. The uppermost formation is composed largely of calc-alkaline dacitic volcanoclastics (Pyke, 1974).

In 1975, Lorsong subdivided the Porcupine Group into Whitney, Beatty, Dome, and Three Nations formations.

Pyke, in 1976, renamed the six formations from youngest, Donut Lake, Redstone, Boomerang, Goose Lake, Schumacher, and Krist and assigned all metasedimentary rocks to Formation VI as the sole unit of the Porcupine Group. Pyke considered the Porcupine Group to be a time-equivalent of the Upper Deloro and the entire Tisdale Groups. Later, in 1978, he renamed the Tisdale and Deloro Groups the Upper and Lower subgroups respectively. He also raised Formations I through VI to Group status but, according to Brisbin (1997), this reorganization did not meet with universal acceptance.

Intrusive rocks and selected volcanic rocks of the Timmins area were dated using U-Pb zircon methods by Frarey and Krough (1986), Mortensen (1989), and Corfu et al. (1989).

In 1988, Mason et al. suggest that the emplacement of the porphyry intrusive rocks prepared the host rock for subsequent hydrothermal fluid migration and gold mineralization. Fracturing and brittle faulting generated prior to intrusion of the porphyries during a period, or periods, of magmatic tumescence resulted in highly fractured centres that were subsequently exploited by hydrothermal mineralizing systems. The eruption of the Krist Formation pyroclastic rocks and Keewatin folding and faulting may have also initiated ground preparation and localized magmatic and hydrothermal activity.

In 1991, Jackson and Fyon defined a lithostratigraphic association of rock units in the Western Abitibi Subprovince within the boundaries of 55 tectonic assemblages. An assemblage is defined as stratified volcanic and/or sedimentary rock units built during a discrete interval of time in a common depositional or volcanic setting. Jackson and Fyon (1991) suggest a four stage evolutionary model for the Southern Abitibi Greenstone Belt:

·Formation of submarine oceanic assemblages in regional-scale, complex micro-plate interactions perhaps caught between two larger converging plates located north and south of the micro-plate region;

·Termination of submarine volcanism by collision of a large continental mass to the south at ~2700 Ma. The collision may have been oblique, involving the 2800 to 3000 Ma Minnesota River Valley gneiss terrane.

·Tectonic thickening during collision led to emergent sediment source area(s) for post ~2700 Ma turbidite deposits, including both local deposits and a massive sedimentary accretionary wedge. As collision continued, previously formed volcanic and turbidite deposits, including the Pontiac Subprovince, were deformed;

·Terminal subduction, possibly involving complex plate interactions at 2685 to 2675 Ma, generated alkalic volcanic rocks and alluvial—fluvial sediments in proximity to crustal—scale shear zones.

In 1992, Melnik-Proud interpreted the gold-bearing quartz-carbonate-albite veins to not only be spatially, but temporally and genetically associated with albite dykes found in the Hollinger-McIntyre complex.

Brisbin defined the Krist as a formation within the Hoyle Group in 1997. He proposed and assigned a new lithostratigraphic unit termed the Hersey Lake Formation. This unit is composed of intercalated ultramafic and mafic flows that compose the base of the Tisdale Group in the core of the North Tisdale Anticline. Correlative flows are exposed in the south, on the Delnite, Aunor, and Buffalo Ankerite mine properties. The upper contact of the Hersey Lake Formation is defined as the upper contact of the highest ultramafic flow in the Tisdale Group (Brisbin, 1997).

In 1999, Pressacco is published in Ontario Geological Survey Special Project: Timmins Ore Deposits Descriptions.

Ayer et al. (2000), with the aid of additional remapping and geochronological data, proposed a reinterpretation of the Jackson-Fyon Tectonic Assemblages, reducing the number from 55 to nine including seven volcanic and two metasedimentary assemblages. Presently, the assemblages are interpreted as autochthonous, not allochthonous. Geochemistry of the volcanic units indicates an interaction between plume and subduction zone melts. The Porcupine assemblage is interpreted to be the result of submarine turbidite fans which are coeval with batholith emplacement, regional folding, and collision with the Opatica Subprovince. The Timiskaming assemblage is believed to be the result of subaerial alluvial fan-fluvial sedimentation associated with continental arc magmatism.

The Discover Abitibi Initiative (DAI) began as a regional economic development venture, which ran from 2001 to 2012 and had a mission to stimulate mining development by encouraging increased exploration in the Timmins-Kirkland Lake corridor. The DAI coordinated and directed an integrated geoscientific investigation of the Abitibi Greenstone Belt (Discover Abitibi, 2010). While active, the DAI brought together the talents of geologists, prospectors, mining industry leaders, the OGS, and the Geological

Survey of Canada (GSC) to the Timmins - Kirkland Lake Gold Camps to assess the fundamental architecture and processes which were responsible for the gold and base metal endowment.

In a recent paper, Bleeker (2012) discusses the growing recognition that crustal extension may have played a critical role in the formation of orogenic gold deposits as opposed to the long held theory of terrane accretion, thrusting, crustal shortening and a final metamorphic cycle. Bleeker’s conclusions are, “From the overall model, it is concluded that the major breaks were initiated as first-order extensional faults (Bleeker, van Breemen and Berger 2008) reaching deep into the crust, if not the uppermost mantle. Lithospheric thinning, basin formation and alkaline magmatism accompanied the extensional phase and may have been critical to overall gold endowment, even though peak gold deposition may have occurred somewhat later during renewed shortening. Following extension, the main breaks were inverted as thick-skinned thrusts that tectonically buried the leading edges of the synorogenic clastic basins. Further shortening rotated the faults to near vertical, with local overturning. Finally, the faults were overprinted by major strike-slip movement and mapped breaks may locally deviate from the critical fault planes that controlled the extension and thrust inversion history. It appears that gold mineralization started during extension, but likely peaked during and following thick-skinned thrust inversion. Deposits along the faults were sliced apart by continued fault movement, with the “missing halves” either advected out of the section and lost to erosion or, more interestingly from an exploration point of view, occurring somewhere along strike along the major strike-slip faults.”

Recent structural studies by Dave Rhys (Panterra Geoservices Inc.) have led to great advancements in recognizing and understanding the structural evolution and controls on mineralization in the Timmins camp and in the vicinity of the Bell Creek Mine. The region is affected by a long lived deformation history which is constrained in timing by the presence of unconformities within the sequence (Rhys 2010). Earliest deformation events include D1, a pre-Porcupine Assemblage phase of folding which is indicated by the local truncation of folds in the Tisdale Assemblage against the unconformity at the base of the Porcupine Assemblage. D1 was followed by a major phase of thin-skinned thrust imbrication and folding that lacks associated foliation, D2, which includes folds and thrust surfaces that are truncated against the Timiskaming unconformity, such as is seen in the Porcupine Syncline, and in the Pamour area. These events are followed by faulting along the Destor-Porcupine faults system, probably coincident with deposition of the Tisdale Assemblages, and then by at least two pulses of syn-tectonic deformation, D3 and D4, which are associated with post-Timiskaming foliation development (S3, S4 foliations). The pre-metamorphic D2 lithologic architecture and faults in the local area likely aided in the localization of later D3 high strain and shear zones, which may have preferentially formed along areas of high rheological contrast, in weaker units such as ultramafic and carbonaceous sedimentary horizons, and along the older D2 thrust surfaces where they are favourably oriented. Field relationships suggest that the mineralization in the district overlapped mainly with the D3 event, and overprints both Timiskaming sediments and older D2 structures (Rhys 2012).

Tectonic assemblages of the Abitibi Subprovince east of the Kapuskasing Structural Zone are shown in Figure 7.1 and summarized in Table 7.1.

7.2PROPERTY GEOLOGY

The Bell Creek properties are underlain by carbonate altered, greenschist facies Archean-aged, metavolcanic and clastic metasedimentary rock units belonging to the Tisdale and Porcupine assemblages. The metavolcanic portion of the stratigraphy represents the lower portion of the Tisdale Group, with the ultramafic metavolcanic rocks belonging to the Hershey Lake Formation (Brisbin, 1997) or Pyke’s (1982) lowermost unit, Formation IV. The mafic metavolcanic variolitic and iron tholeiitic flow units are interpreted as being characteristic of Pyke’s (1982) middle unit, Formation V. The Krist Formation, Pyke’s upper unit, is absent from Hoyle Township (Berger, 1998). The lithologies generally strike east-west, to west-northwest, and are steeply dipping.

The ultramafic metavolcanic rocks are comprised of massive, spinifex, and polysutured textured flows and derived schists. Ultramafic schist is characterized by a fissile habit, abundant talc, and Mg-rich chlorite and carbonate (Berger, 1998). Limited whole rock analyses completed on the lithologies in Hoyle Township indicates the lower ultramafic metavolcanic rock unit to be basaltic komatiite (Berger, 1998; Pressacco, 1999). Kent (1990) describes the ultramafic rock sequence at Bell Creek as a lens-shaped unit that forms pods 100 metres to 200 metres thick, which locally exhibits intense ankerite-fuchsite alteration.

The mafic metavolcanic rocks exhibit massive, pillowed and breccia flow textures. Berger (1998) observed that stratigraphic tops of the pillows consistently faced to the south or the west in the Tisdale assemblage within Hoyle Township. Based upon the west facing pillow, Berger believed there was no evidence that the mafic metavolcanic rocks of the Tisdale assemblage were folded. Several thin interflow sedimentary horizons present within the mafic sequence (Kent 1990), can be seen underground to locally change in strike from east-west to more northerly trends and are now interpreted (Rhys 2012) to be associated with asymetric D3 and D4 folds of an overall northwest trending stratigraphy. Flow units occur with a flow top breccia which exhibits a gradational contact into a pillowed base. Variolitic flows are common within the mafic volcanic sequence. A correlation of the variolitic flows of the Bell Creek deposit area with the variolitic flow of the Tisdale Group, especially the V10 (Vipond Formation) flow unit is implied, but has not been verified by detailed mapping and geochemical testing. The mafic schists occur as a fine grained fissile unit that weathers a dark green to orange brown colour. Common to Pyke’s Middle Formation of the Tisdale assemblage are leucoxene bearing Fe-rich tholeiitic basalts. The presence of abundant leucoxene has been used to distinguish between the lower formation Mg-rich basalts (leucoxene absent) and the Fe-rich tholeiitic basalts. Whole rock analysis results returned from six of Berger’s (1992, 1994) samples plotted as Fe-tholeiites

(three samples), calc-alkaline basalts (two samples), and tholeiitic andesite (one sample) (Pressacco, 1999).

The metasedimentary rock units are composed of wacke, siltstone, mudstone, graphite, and pyritic mudstone and are correlated with the Hoyle assemblage (Jackson and Fyon, 1991; Berger, 1998). The Hoyle assemblage has been redefined as a formation and is an extensive part of the Porcupine assemblage, which includes the Beatty Formation of metasedimentary rocks located in the core of the Porcupine Syncline (Bateman et al., 2005). Wacke beds vary from 5 mm to over 1 metre thick and display grain gradation. Chlorite and sericite are the most common alteration minerals in the matrix, whereas biotite is absent in most metasediments in Hoyle Township. Siltstone is rare in the Hoyle assemblage, occurring as thin layers overlying wacke beds. Green, grey, and dark grey mudstone occurs throughout the Hoyle assemblage overlying wacke. Graphite and amorphous carbon are the major opaque minerals and comprise less than 5% of the rock. Graphitic and pyritic mudstone is a distinctive rock type that generally occurs along, or within, 400 metres of the contacts with mafic metavolcanic rocks. Pyrite comprises from 1% to 30% of the graphitic mudstone and occurs in two forms, as nodular pyrite balls that are 1 mm to 2 cm in diameter, and as disseminated to massive laminated or bedded layers 1 mm and 10 mm thick (Berger, 1998).

Intruding the Archean rock units is a north-south trending swarm of diabase dykes which has been correlated with the Paleo-Proterozoic age Matachewan swarm. This mafic intrusive unit contains up to 15% magnetite and weathers an orange-brown colour. Berger (1998) describes a Cretaceous regolith that was intersected in several reverse circulation overburden drill holes in Hoyle Township. He describes the unit as being a green to gold coloured, gritty clay that is commonly indurated and locally forms a hardpan layer. This unit indicates that Archean rocks were subjected to intense laterite-like weathering.

Overlying the Archean bedrock is the Quaternary geology unit of the Barlow-Ojibway Formation. This is a sequence of glacio-lacustine deep water varved silts and clays overlain by gravel and clay till of the Matheson till sheet. Recent organic deposits, of black mud and peat, overlie the Quaternary geology.

The structural setting of the Bell Creek property is complex. The deposit is said to be situated north of the North Tisdale Anticline, within an Archean-aged metavolcanic and metasedimentary rock synclinal fold/fault sequence, and is positioned between two D2 reverse faults (Powers 2009). Bateman et al. (2005) interpret the thrusting as the formation of the North Tisdale Anticline D2 and F2 events. The strike is parallel to the surface traces of the thrust plane and anticlinal axis. Stratigraphic tops point to the south and, near surface, the rock units dip steeply south. At depth, the dip undulates to vertical and changes to steep north dipping. Bateman et al. (2005) illustrate an F4 northeast-southwest synclinal axis at Hoyle Pond Mine. Rhys (2004) illustrates the Hoyle Syncline, north of the North Tisdale Anticline as D1b fold event and that Bateman’s F4 synclinal axis parallel to the 1060 Zone at Hoyle Pond Mine is a D2 synclinal fold event. Since then, more recent work by Rhys provided some modifications to the structural history, with the addition of at least one early folding event preceding the Temiskaming Assemblage. This proposed structural history is compatible with that presented in Bateman et al (2005), apart from the post-metamorphic interpretation of the relative timing of the S3 deformation with respect to the Timiskaming Assemblage (Rhys 2010). “The overall setting of the Bell Creek deposit occurs in an area of lithologic complexity and rheological contrasts. The sequence of mafic and ultramafic volcanic rocks of the Tisdale Assemblage form a series of interleaved, easterly thinning wedges which alternate with eastward thickening bands of younger turbiditic sediments of the Porcupine Assemblage. Mapping and compilation of facing indicators from drill core (graded bedding,

etc.) at the Hoyle Pond, Owl Creek, and Pamour deposits and the Wetmore prospect indicate that the lithologic sequence is dominantly south facing. This suggests that the alternating volcanics and sedimentary bands represent interleaved thrust panels related to D2, pre-metamorphic and pre-Temiskaming deformation event in the area, rather than a series of alternating anticlines and synclines as has previously been interpreted across which bedding facing directions should change. Like the Porcupine Syncline in the central Timmins district (Tisdale Township), major thrust panels, and carbonaceous thrust faults which lie along the south side of the mafic belt, are truncated against the Timiskaming unconformity in the Pamour-Hallnor area to the southeast of Figure 7.2” (Rhys 2012). The dominant syn-metamorphic foliations, S3 and S4 related to post-Temiskaming D3 and D4 events, regionally obliquely cross, and are superimposed on the series of thrust panels (Rhys, unpublished data).

7.3MINERALIZATION

7.3.1Overview

In the Porcupine Camp, gold bearing structures most commonly form in relatively competent volcanics intruded by felsic porphyry stocks and dykes prior to the deposition of the Timiskaming assemblages. Porphyries dating from 2691 ± 3 Ma to 2688 ± 2 Ma intruded the already folded and faulted greenstone sequences and initiated the mesothermal systems with the formation of associated albitites. Observations of pyrrhotite and gold-mineralized clasts at both Pamour and Dome mines within Timiskaming conglomerates suggest a prolonged gold deposition event from the creation of the steep south dipping DPFZ up to the latest episode of crustal stabilization (Butler, 2008).

Fracture intensity and alteration increase toward mineralized zones. Alteration consists of bulk and fracture-controlled sericite, Fe-dolomite to ankerite, quartz, and dark green to black chlorite. Microfractures contain late chlorite and carbonate veinlets. Distal carbonatization, resulting in grey carbonate zones, is quite common (Butler, 2008).

Berger (1998) describes the gold mineralization in the Bell Creek area as occurring along selvages of quartz veins and wall rocks, in stylolitic fractures in quartz veins, in fine grained pyrite, and in association with amorphous carbon. High grade gold mineralization occurs within quartz veins contained in alteration zones. The alteration zones are characterized by carbonate, graphitic and amorphous carbon, fine grained pyrite, sericite, and/or paragonite and are enriched in Au, As, Bi, and W. This style of alteration is referred to by mine geologists as “grey zones” and is an exploration target in Hoyle Township.

Kinross and Pentland Firth Ventures (PFV) first coined the term “New Mines Trend” to describe areas of the Hoyle “antiform and synform” that host the current and past producing Hoyle Pond, Owl Creek, Marlhill, and Bell Creek mines and the Schumacher and Vogel advanced exploration projects. More recently, structural work by Rhys (2003, 2012) suggests that the alternating volcanic and sedimentary bands in the area represent interleaved thrust panels, where wedges of mafic volcanic, sedimentary, and deformed ultramafic rocks converge in the vicinity of the deposit. The occurrence of variably oriented lithologies of various deformational (rheological) strength and thickness in the lithologic sequence likely contributed to local complex strain patterns during regional syn-metamorphic deformation. Carbonaceous units (i.e. interflow sediments) may have had important controls on the position and orientation of mineralized shear zones which locally exploit them (Rhys 2012).

7.3.2Bell Creek Mine

The Bell Creek mineralization differs in style from many deposits in the Porcupine Mining camp in being composed largely of disseminated pyrite-pyrrhotite-related mineralization; slightly younger gold-bearing quartz veins may be present but are not predominant. This style of mineralization occurs in the deeper parts of the Dome Mine and in the Rusk Zone at the Timmins West mine, but is more common to the east, in the Holloway-Holt McDermott area and at the Larder Lake, where pyritic mineralization is often termed “flow ore” (Rhys 2012).

The most significant gold mineralization at the Bell Creek Mine occurs in two lithostructural settings: a) near or along an ultramafic-to-mafic contact zones (the Bell Creek and West Zone), and b) within the mafic volcanics sequence (North Zones).

7.3.3Bell Creek and West Zones

The Bell Creek and West Zones were discovered in 1980 while drill testing electromagnetic conductors and IP anomalies. Kent (1990) describes the Bell Creek West Zone mineralization as occurring on or near the contact of the ultramafic metavolcanic and mafic fragmental metavolcanic rock units, with the latter as the preferred host. Mineralization consists of 2% to 10% pyrite, with accessory arsenopyrite, pyrrhotite, chalcopyrite, and minor quartz veins and veinlets. Approximately 90% of the gold is associated with the disseminated sulphides that occur in association with altered quartz-carbonate-sericite-sulphide zones that range from 0.5 metres to 7 metres in width. Lenses that are approximately 100 metres in length and 200 metres in vertical extent strike west-east and plunge steeply to the east. Multiple mineralized zones are identified along a one kilometre strike length of the mafic/ultramafic metavolcanic contact, which runs across the southern part of the mine. Active carbon occurs in some of the mineralized pods in the form of sheared graphitic interflow sediments. The presence of the active carbon has a deleterious effect on gold recovery; consequently mining was not planned where this was encountered (Kent, 1990), and only a small portion of the zones were mined in the upper levels of the mine prior to 1992. Potential for better grades and recoveries further along strike and at depth still need to be assessed.

7.3.4North Zones

The North Zones at Bell Creek were intersected in 1981 while targeting IP anomalies. The vein system consists of two main sub-parallel horizons, roughly 40 to 60 metres apart, historically referred to as the North A and North B zones. They occur within mafic volcanic rocks, approximately 200 metres north of an ultramafic contact and north of the Bell Creek headframe. Mineralization within the zones trends east west to west-northwest and dips steeply to the south or southwest. The mineralization is locally deflected as in intersects and exploits a 0.5 to 10 metre wide band of carbonaceous interflow (?) sediments. Mineralization forms vein-replacement networks along probable minor shear zones which are approximately parallel to the S3 foliation, although S3 locally trends slightly more northeasterly than the zone, especially where the zone rotates to the northwest trends, refer to Figure 7.3 (Rhys 2012).

Collectively, the North Zones have an overall plunge which is steep to the east and has been traced continuously by drilling below 1,680 metres vertical depth, and remain open at depth. Overall plunge of the system is approximately parallel to L4 lineation, and is similar to the steep easterly plunge of the 1060 Zone at the Hoyle Pond mine. Internally, steeper plunges to the west of thicker, high grade segments of the zone are apparent, forming more local, stope scale ore shoot plunges at bends in the structures (Rhys 2012).

To date, the North A and North B Zones extend up to 500 metres along strike, and remain open at depth, 1,680 metres below surface. The zones locally branch or break into strands which define at least nine principal domains of gold mineralization, three (3) of which contain 80% of the total resource (refer to Item 14).

Results from recent drilling and underground development have shown that the North Zones consist of at least 16 mineralized zones, 14 sub-parallel and two oblique or splay zones. Figure 7.4 shows the NA, NA4, NB3, NB2 and HW3 development and mapping that was completed on the 715 Level along with the drill interpreted locations (red outlines) of the NA2, NA3, HW5 and HW6 zones. The albite, ankerite, pyritic gold bearing alteration is shown in yellow with quartz, locally gold bearing veins are in red.

The geometry of the mineralized zones has changed in the 200 vertical metres from the 505 level with the North A zone losing the dramatic bend linking the “north” and “south” strands. On the 715 Level the North A shows a general west to east trend with two more gentle bends, one where it converges with the HW2 zone and again where it intersects the NA4 zone. Consequently the hangingwall (south) and footwall (north) strands as identified by Rhys (2102) are not as pronounced on the 715 Level. The majority of the zones on the 715 Level follow the S3 foliation trends as identified by Rhys (2102) while the HW2 and NA4 zones conform to the S4 foliation trends.

North A Zone

The North A Zone outcrops approximately 200 metres north of the Bell Creek headframe and consists of a marker quartz vein that varies from 0.1 metres to 2 metres in width with an associated alteration halo. Approximately 0.5 metres in average width, the vein parallels the regional schistosity and cross-cuts lithology. Bright green hydromuscovite occurs as fractures and slip coatings in the vein, with visible gold occurring with the mica. Brown tourmaline (dravite) is ubiquitous. The North A Zone can typically average 6 g/t Au to 10 g/t Au over 2 to 10 metre widths. Adjacent to the quartz marker vein is a pale grey to buff coloured altered zone (carbonate-albite+/-sericite — Hicks 1986) which contains 5% to 15% pyrite and pyrrhotite, with accessory chalcopyrite and arsenopyrite. Trace amounts of pentlandite, arsenopyrite and cobaltite have also been reported (Miller 2011). Up to 30% of the gold in the North A Zone occurs within the alteration halo, in discrete sulphide zones and in vein-brecciated wall rock zones that extend up to 5 metres from the margin of the core vein.

North B Zone

The North B Zone occurs 40 to 60 metres further north, and runs essentially sub-parallel to the North A zone. In this case, the zone is predominantly hosted by the same interflow carbonaceous sediment which is locally transected by the North A Zone. Brittle faulting exploits the carbonaceous unit, forming east-west to west-northwest trending fault surfaces with thin seams of black carbonaceous gouge that run parallel to the zone (Rhys 2012). Historically, portions of the wall rocks were thought to contain active carbon, which was determined to be detrimental to gold recovery (Kent, 1990). Overall, mineralization is narrower, quartz vein abundance is higher, and grades are lower than in the North A Zone.

8.0 DEPOSIT TYPES

The Porcupine area is well known for hosting two mineral deposit types: 1) Xstrata’s Kidd Creek Mine, which is a volcanogenic massive sulphide deposit; and 2) several mesothermal Archean shear-hosted gold deposits. Gold production to the end of 2013, from some 60 operational and historical sites is reported to be 2,171,575 kilograms of gold (69,817,744 ounces of gold). Table 8.1 highlights the 26 locations that exceeded production of 3,110 kilograms of gold (100,000 ounces of gold).

Approximately 15% of the gold mined to date in the Porcupine Camp has come from bulk tonnage, sheeted vein and stockwork deposits, and, to a lesser extent, from narrow veins hosted in Timiskaming-aged sedimentary rocks. These deposits have been mined at the Dome Mine in Tisdale Township, and at the Pamour, Falconbridge Hoyle, Broulan, Hallnor, and Bonetal mines in Whitney Township.

Mesothermal gold deposits comprise high Fe or high ratio Fe/(Fe + Mg) greenstone type rocks that induce sulphidization reactions and gold precipitation and are thought to have formed during the final orogenic phases of Archean tectonism. Regionally, deposits occur in the vicinity of large deformation zones associated with secondary or tertiary deformation. Cox (2000) describes the development of most mesothermal gold systems along active and permeable low displacement faults and shear zones adjacent to large crustal scale deformation zones. Clusters of large deposits commonly occur in greenschist-facies, and, to a lesser extent, amphibolite-facies, country rocks (Butler, 2008).

9.0 EXPLORATION

Lake Shore Gold (LSG) has been actively exploring in the Bell Creek area since the Schumacher property acquisition in 2005. This work has been completed with reference to the historic Bell Creek coordinate system which has been extended to cover the property extents. The property boundaries have been located and referenced with respect to this control grid.

To date the bulk of the exploration work has been focused on delineating, defining and extending the mineralization contained within the North A and North B zones which were previously identified or exploited underground. Initially, exploration activity had been focused on surface diamond drilling although a geophysical magnetometer survey was completed to assist in defining stratigraphy. An advanced exploration ramp was collared at UTM, NAD 83, Zone 17 coordinate 486,814 East, 5,377,603 North on June 6th, 2009. The 5.0 metre high by 5.0 metre wide ramp provides access to all zones, especially the North A Zone, as well as providing diamond drill platforms to further define mineralization.

This work led to the preparation of NI 43-101 compliant Mineral Resource estimate in 2010. Effective date for this update was October 25th, 2010.

Current exploration is comprised entirely of underground diamond drilling, while development of waste in ramps and crosscuts and development of the mineralized zones, predominantly the North A continues. A summary of exploration work completed by LSG to the date the database was locked down, December 17, 2014, is summarized in Table 9.1.

After the acquisition of the Schumacher property, drilling was conducted to test the flat veins located in the eastern portion of the property. These vein sets are not considered part of the Bell Creek Resource. In 2006, three stratigraphic holes totaling 3,307 metres in aggregate length were followed by three shorter holes (totaling 546 metres) along the margins of the gold-bearing zone. Later, in Q3 of 2006, LSG drilled an additional 912 metres in three holes in an attempt to determine a shallow bedrock

location for a potential ramp portal entrance. In addition to the standard core logging procedures, these holes were logged for Rock Quality Designation (RQD) (Butler, 2008).

Drilling completed on the Schumacher property between 2009 and 2011 was completed to test the down dip and down plunge extensions of the Bell Creek North A and North B Zones. These drill holes are included in the preceding chart.

10.0DRILLING

Diamond drilling in the general vicinity of the Bell Creek deposit has been conducted by several entities with the first recorded drill hole assessment files being completed in 1940 (Alton C.B. Township 1, Concession 9). Early drilling records lack assay results or identifiable collar locations. For this reason, the description of diamond drill programs begins with the Rosario Resources Canada Ltd. drilling completed in 1978. Drilling completed prior to the acquisition of the previously described claim group by Lake Shore Gold (LSG) is described as historic drilling, and consists of 73,294 metres in 546 holes.

The Rosario Resources Canada Ltd. drilling (1978 to 1981) consists primarily of North to South oriented drill holes (360 degree azimuth). Drilling in 1978 and 1979 was in the general area with no drill holes collared within 1,000 metres of future mine workings.

The North A and North B veins were first intersected in 1980. Strike of veining is at 100 degrees dipping 70 degrees south yielding intersections approximately normal to vein strike (10 degree variance).

Amax Minerals Exploration Ltd. and Canamax Resource Inc. surface drilling between 1982 and 1990 was completed at 30 metre centres on a north south oriented grid presently referred to as the Bell Creek Mine grid. Collar orientation for most drill holes was 360 azimuth yielding intersections approximately normal to the strike of the vein (10 degree variance).

Underground diamond drilling by Canamax Resources Inc. (1988 through 1991) and Falconbridge Gold Corporation (1991 through 1994) was completed from diamond drill cut-outs with various collar azimuths and dips to provide coverage. Intersection angles vary considerably.

Subsequent surface drilling by PFV and PJV was oriented using the Bell Creek Mine grid, predominantly with 360 degree azimuth drill collars.

Drill holes BC05-31 to BC05-36 completed by PJV were collared east of mine workings and oriented at 330 degrees, presumably to compensate for downhole deviation.

Significant diamond drill intersections from historic drilling are listed in Appendix B.

10.2LAKE SHORE GOLD DRILLING

All work performed on the Bell Creek Complex is referenced to the Bell Creek Mine grid which has been extended eastward through the Schumacher and Vogel properties. Proposed diamond drill hole collar locations for both surface and underground are located or “spotted” in reference to this grid.

Drill holes completed from surface and underground are monitored downhole in 30 and/or 50 metre intervals. As with most properties drill holes at Bell Creek deviate, both in azimuth and dip, furthermore the longer the holes the greater the deviation. Tracking the deviation in shorter holes can be accomplished by using a magnetic downhole survey tool to measure dip and azimuth (relative to magnetic north). Over the course of the Bell Creek drilling, these downhole surveys were accomplished using either of the “EZ-SHOT” or “EZ-TRAC” survey instruments manufactured by Reflex™.

Generally, the rocks at Bell Creek are non-magnetic so acquiring an accurate measure of deviation for short holes can be acquired using these instruments. For longer holes where deviation is more excessive determining the location of a hole becomes problematic, especially if the drilled rock contains magnetic material, consequently a gyroscopic survey tool is used to acquire the downhole survey data.

10.2.1Surface Drilling

A total of 280 surface and wedge-holes were completed by LSG since the acquisition of the property, for a total of 137,594 metres drilled. Most of the drill holes were NQ-size, except where it was necessary to reduce to BQ-size when technical difficulties were encountered. Drilling was mostly focused on infilling and expanding the North Zones, with a minor portion directed towards exploration of new mineralization zones. Depending on drill contracts and drill rig availability, the program was carried-out

by drilling contractor Bradley Bros. Ltd. of Timmins, Orbit Garant of Val-d’Or, Quebec, and by Norex Diamond Drilling Ltd. of Porcupine, Ontario.

On a regular basis or as required, the collars were surveyed by, L. Labelle Surveys of Timmins, and a final collar location is provided in reference to the mine grid and UTM, NAD 83, Zone 17 coordinates.

If the drill-hole trajectory needed adjustment, steel wedges were used. When required, directional drilling was provided using “mud” motors operated by technicians from International Directional Services (IDS), based out of Capreol, Ontario. Upon completion of a drill-hole the normal practice is to have the holes resurveyed using a north-seeking gyro by Halliburton/Sperry Drilling Services of North Bay, Ontario. The holes were then plugged and cemented below the casing, and the casing was left in place, capped, and labeled for future reference. Flattening of longer surface diamond drill holes (typically greater than 800 metres depth) results in intersections approaching true thickness.

Figure 10.1 shows all surface drilling completed by LSG for the Bell Creek Mine while Figure 10.2 shows a typical cross-section of the surface drilling.

10.2.2Underground Drilling

Since LSG acquired the Bell Creek property in 2007 a total of 118,726 metres (923 holes) of underground drilling has been completed. This total includes recently completed holes totaling 46,037 metres in 387 holes which had been completed during the period November 1st, 2012 and December 17th, 2014. Prior to November 1st, 2012, the effective date of the March 2013 technical report, 536 holes (72,689 metres) were completed from underground. This drilling had been carried-out by one of two contractors, Boart Longyear, out of the North Bay, Ontario office (headquartered in Salt Lake City, Utah) or Orbit Garant of Val-d’Or, Quebec.

For underground holes longer than 350 metres the Reflex™ Gyro was used to survey holes. This instrument is a micro-electrical-mechanical system or MEMS gyro.

Current drilling at Bell Creek is being conducted from underground and is a mix of definition, infill, exploration and holes completed from within the “ore” sills to ensure that the mineralized zones have been fully developed prior to mining.

The drill-hole database for the Bell Creek Properties was locked down on December 17th, 2014. At the time, drilling, core logging and sampling of the most recently finished holes was completed, and no assay data was pending. Details on core handling and sampling protocols are reported in Item 11.

10.3LAKE SHORE GOLD DRILL RESULTS

Diamond drilling has identified 16 mineralized zones (14 sub-parallel and two splay zones) that comprise the North A and North B vein systems and which extend from surface to a vertical depth of approximately 1,700 metres. Mineralization remains open down plunge and to the east at depth. For reference, diamond drill pierce points for the North A domain are presented in Figure 10.5.

11.0SAMPLE PREPARATION, ANALYSIS, AND SECURITY

Sample preparation, analysis and security for the period 1978 to 2012 are described in the independent reports Technical (Geological) Report on the Bell Creek Complex (Hayden 2008), A Technical Review and Report For The Bell Creek Complex Properties’, Exploration Diamond Drill Programs, August 2005 to July31, 2009 (Powers, 2009), Technical Report on the Initial Mineral Resource Estimate For the Bell Creek Mine, Hoyle Township, Timmins, Ontario, Canada (Pressacco, 2011) and the Lake Shore Gold (LSG) NI 43-101 Technical Report, Resource Estimate Update and Prefeasibility Study and Mineral Reserve Estimate for Bell Creek Mine, Hoyle Township, Timmins, Ontario, Canada (Crick, Koch and Vaz, 2013)

11.1HISTORIC: PRE-LAKE SHORE GOLD

In the opinion of the author, the procedures and practices employed by the various operators at Bell Creek prior to LSG’s involvement conform to industry standards that predate the adoption of NI 43-101, and that this information is suitable for use in resource estimation. Details are summarized in the following sections.

11.1.1Sample Preparation and Analysis

Rosario Resources Canada Ltd.

Descriptions of sampling methods or approaches have not been located for drilling completed by Rosario. A review of drill logs indicates that samples were taken from the collar to the toe of the hole in increments adjusted to the nearest foot or half-foot, based on mineralogy and lithology.

Details of sample preparation and assay procedures for samples processed for Rosario are not known. It should be noted that only one diamond drill hole from this period falls within the resource volume.

Diamond drill core does not exist from Amax/Canamax surface drilling or Canamax/Falconbridge underground drilling. Review of the drill logs for the surface-based drill holes indicates that selective sampling of the drill core was done with a nominal sample length of one metre. Sample lengths greater or less than one metre were adjusted to correspond to mineralogical or geological boundaries such as veining, variation in accessory mineralization and changes in lithology. All surface-based drill core was systematically split for sampling.

Review of drill logs for the Canamax and Falconbridge Gold underground drilling indicates that selective sampling of drill core was done based on geologic boundaries such as veining, variation in accessory mineralization or lithology. It is not known if the drill core was split or whole core sampled.

All core drilled for PFV is stored at the Bell Creek core farm. Review of the drill logs and drill core indicates that selective sampling was done based on geologic boundaries such as veining, variation in accessory mineralization or lithology. The drill core was split with the exception of those samples containing visible gold. These samples were whole core sampled without being split or sawn in half (identified in log as “whole cored”).

A review of drill logs for the PJV surface drilling indicates that selective sampling of drill core was done based on geologic boundaries such as veining, variation in accessory mineralization or lithology. According to a PJV report on the 2005 Exploration Program at the Bell Creek Mine, “all holes were

Technical Report, Bell Creek Mine, 27 March 2015

56

sampled by whole core sampling, except for the high-grade sample in BC05-02 which was sawn for display”.

Assay certificates are not available for most of the historical diamond drilling completed before LSG’s acquisitions of the properties (Powers, 2009).

It is not known which lab completed gold assays for Rosario resources. All samples assayed for Amax, Canamax surface drilling, and PFV were processed at Swastika Laboratories Ltd. (Swastika Labs) in Swastika, Ontario.

Swastika Labs is an independent lab and has a Certificate of Laboratory Proficiency, CCRMP ISO 9001:2000, and PTP-MAL for specific mineral analysis parameters (Au, Pt, Pd, Ag, Cu, Pb, Ni, Co). PTP-MAL uses criteria for laboratory proficiency managed by the Canadian Certified Reference Material Project (CCRMP) in co-operation with the Task Group Laboratories Mineral Analysis Working Group of the Standards Council of Canada.

All samples were processed utilizing a 0.5 assay ton fire assay process with AA finish. At lower detection limits for geochemical work or, where required, the Au particle or doré bead is dissolved and determined by Atomic Absorption Spectrophotometry.

All samples obtained through drilling from underground mine workings were processed at the Bell Creek Mine assay laboratory. This includes the drilling completed by Canamax (1988 to 1991) and Falconbridge Gold (1992 to 1994). The Bell Creek Mine assay laboratory conducts in-house analysis of mill, underground, and drill core samples and is not an ISO 9001-2000 registered laboratory.

All samples assayed for the PJV Bell Creek drill program in 2005 were assayed by SGS Geochemical Laboratories (SGS) in Rouyn-Noranda, Quebec. The SGS laboratory in Rouyn-Noranda is an ISO 17025 certified facility. Samples were assayed using a 1 AT aliquot with an AAS finish.

11.1.2Security

Records could not be found regarding security practices employed prior to 1982, by Rosario. It should be noted that only one diamond drill hole from this period falls within the resource volume.

Surface drilling for Canamax and Amax was completed by St Lambert Drilling Ltd., with frequent unscheduled site visits by the supervising geologist to ensure safety, good working practices, and drill core security. Drill core was delivered by the drill foreman to an on-site logging facility and was logged by graduate geologists who oversaw the sampling of the core. Samples were packed in cardboard boxes sealed with packing tape and shipped via ONR Bus service to Swastika Labs. Pulps and rejects were returned from the laboratory but are no longer available (pers. comm. Ken Tylee, P. Geo. 2009).

Drill core from underground drilling for Canamax was brought to the surface logging facilities by the drill foreman. Samples were brought directly to the Bell Creek assay laboratory by Canamax personnel (pers. comm. Ken Tylee, P. Geo. 2009).

Security practices employed by Falconbridge Gold for underground drilling at Bell Creek are not known.

Surface drilling for PFV (1995) was completed by Norex, with frequent unscheduled site visits by the supervising geologist to ensure safety, good working practices, and drill core security. Drill core was

Technical Report, Bell Creek Mine, 27 March 2015

57

delivered by the drill foreman to an on-site logging facility and was logged by graduate geologists who oversaw sampling. Samples were packed in cardboard boxes sealed with packing tape and were picked up by Swastika Labs personnel or brought direct to Swastika Labs by PFV personnel. Pulps and rejects were returned from the laboratory but are no longer available (pers. comm. Ken Tylee, P. Geo. 2009).

Drilling was completed for PJV in 2005 by Bradley Brothers. Drill core was delivered to the Owl Creek core shack by the drill foreman and was logged by PJV personnel. Samples were packaged in fibre bags, sealed with security tags, and shipped via Manitoulin transport to the SGS Labs in Rouyn-Noranda, Quebec, for analysis (pers. comm. Ken Tylee, P. Geo. 2009).

11.1.3QA/QC

It is not known whether Certified Reference Material (CRM) or blank samples were used by Rosario. It should be noted that only one diamond drill hole from this period falls within the resource volume.

Duplicate CRM samples were processed with drill core samples forwarded by Amax, Canamax, and PFV as part of Swastika Labs’ in house quality assurance/quality control (QA/QC) program. CRM standards in use at the time were Canmet MA-1 and Amax’s Au 7 and Au 9. Results of duplicate analyses were returned and are recorded on drill logs. Check analyses were not completed by an independent assay laboratory.

Check analyses were not completed on underground diamond drill core assayed at the Bell Creek assay laboratory.

Sampling and assaying carried out for the PJV followed the standard PJV QA/QC procedure which included the insertion of one CRM, one blank, and one duplicate for each of the 20 samples assayed. According to the PJV report on the 2005 Exploration Program at the Bell Creek Mine, “no major issues were identified as a result of this QA/QC program” (Powers, 2009).

11.2LAKE SHORE GOLD

In the opinion of the author, the procedures and practices employed by LSG conform to or exceed industry standards and that this information is suitable for use in resource estimation. Details are summarized in the following sections.

11.2.1Core Handling, Logging Protocols, Sample Preparation and Analysis

Drill core obtained from surface diamond drill programs was delivered daily to LSG’s core logging facility at either the 1515 Government Road or the 216 Jaguar Road exploration offices in Timmins, Ontario.

Under the direct supervision of the Senior Project Geologists, Stephen Conquer, P. Geo. or Richard Labine, P. Geo., LSG personnel open the boxes; check the metre markers for accuracy and errors; label the boxes with the hole number, box number and footage; prepare a quick log of the contained major geological, alteration and mineralization features. Drill core is then photographed prior to logging or sampling.

A detailed log of the diamond drill hole was completed by a graduate geologist or geological technician and entered directly into a computer database using the Geovia GEMS Logger custom drill hole logging software. The logs document rock characteristics such as lithology, alteration, mineralization, veining,

Technical Report, Bell Creek Mine, 27 March 2015

58

as well as documenting sample numbers, intervals and assay results. Sample intervals are marked directly on the drill core with china marker and a sample tag inserted. Sample intervals range from 0.3 metres to 1.5 metres in length, with an average sample length of 0.8 metres. The core sample length is determined by the geologist based upon lithology, alteration, percent sulphides and the presence of visible gold. Samples do not cross the geological boundaries as determined by the geologist. Duplicate, blank, and standard samples are inserted at this point.

After geological logging is complete, the core is given to a trained and supervised core technician. Core to be sent for analysis is cut in half longitudinally using a diamond blade core saw. One half of the core is placed in a plastic sample bag along with a uniquely numbered sample tag. The remaining half of the core is returned to the core box for reference, with the other half of the sample tag stapled into the core box.

All diamond drill core is archived in core racks or cross-piled in a secure systematically indexed core farm at the LSG office compound, or securely cross-piled at the enclosed security patrolled Bell Creek Mine site. The sawn core half not sent for assay is available for reference, metallurgical testing and check-assaying.

All samples are analyzed for gold at various independent laboratories using fire assay with an atomic absorption finish, except for samples sent to SGS Labs, which provided an ICP finish. For samples that return a value greater than 3.0 g/t Au (changed to greater than 10 g/t Au on March 15th, 2011), another aliquot from the same pulp is taken and Fire Assayed (FA) with a gravimetric finish. Occasionally for samples which may include visible gold analysis is requested to be completed using a pulp metallic method. In reporting assay results, the protocol utilized by LSG stipulates that Metallic Assay results override FA with a gravimetric finish, which in turn overrides FA with an atomic absorption or ICP finish.

Drill core obtained from underground drill programs is subjected to the core handling and logging procedures as the core from the surface programs with some exceptions.

·During the period mid-2009 to mid-2013 drill core was logged on-site at the Bell Creek Mine core logging facilities under the supervision of the Chief Mine Geologist (Ralph Koch, P. Geo., 2010 to 2011, and Ivan Langlois, P. Geo., 2011 to 2013).

·Since 2013 core from underground drilling at Bell Creek has been handled and logged at the LSG Government Road exploration office under the supervision of Keith Green, P. Geo., 2013 to 2014 and by Stephen Conquer, P. Geo., 2014).

·Due to the density of drilling and the large amount of core being generated by the underground programs, most holes are whole core sampled. Select exploration holes are retained for future reference with core being cut and sampled as per the normal LSG process.

Assaying facilities used by LSG are summarized in Table 11.1:

PTP-MAL uses criteria for laboratory proficiency established by the Task Accreditation Sub-Committee Working Group for Mineral Analysis Laboratories of the Standards Council of Canada.

ALS Minerals Ltd. is a division of ALS Limited (formerly Campbell Brothers Limited). Sample preparation was completed at the ALS Minerals preparation facility in Timmins, and pulps were subsequently forwarded to the ALS Minerals Ltd. assay laboratory in Val d’Or, Quebec or in Vancouver, B.C. for analysis. These facilities are all registered ISO 9001:2008. The Val d’Or assay laboratory is SCC ISO/IEC 17025:2005 Accredited (#689) and the North Vancouver, BC assay laboratory is also SCC ISO/IEC 17025:2005 Accredited (#579)

SGS Canada Inc. is an independent facility. Sample preparation was performed at the Garson, Ontario facility with pulps being forwarded to the SGS Minerals Services Toronto Laboratory at 1885 Leslie Street for fire assay. The SGS Minerals Services labs are ISO 17025 certified.

The LSG — Bell Creek Lab conducts in-house analysis of mill, underground muck chip, test hole and drill core samples. The Bell Creek Lab as of September 2012 successfully completed the Proficiency Testing Program for Mineral Analysis Laboratories (PTP-MAL), run by the Canadian Certified Reference Materials Project (CCRMP) of Natural Resources Canada (NRCan).

SPJ Labs is an independent ISO 9001:2008 certified facility located at 1150 Kelly Lake Road, Unit 4, Sudbury, Ontario.

Accurassay Laboratories Ltd. is an independent ISO 17025 certified facility with a corporate office located at 126-4026 Meadowbrook Drive, London, Ontario. Sample preparation is completed at the Accurassay Laboratories Ltd. sample preparation facility located at 150A Jaguar Drive, Timmins Ontario. Pulps are forwarded to the Accurassay Laboratories Ltd. main laboratory facility located at 1046 Gorham Street in Thunder Bay, Ontario for analysis.

After processing, all reject and pulp material is returned to LSG and is stored at the Bell Creek Core Farm where it is available for future evaluation.

Technical Report, Bell Creek Mine, 27 March 2015

11.2.2Security

For both surface and underground drill set-ups, the diamond drill contractor secures the drill core at the drill site. The drill foreman or LSG core technicians bring the drill core to the designated logging facility daily. Both surface and underground core logging facilities are considered secure. The exploration facilities have limited access and are locked and alarmed overnight. Mine site facilities have limited day time access, are locked overnight and are located within the gated mine site.

Samples to be sent for analyses are placed in shipping bags that are sealed with a numbered security seal by LSG personnel. These bags are shipped to the assay facility utilizing LSG personnel. LSG personnel are not involved in any aspect of sample preparation after core specimens are delivered to the assay laboratory.

11.2.3QA / QC

LSG has implemented a quality-control program to ensure best practice in the sampling and analysis of the drill core.

The QA/QC program involves inserting one blank, one CRM standard and one pulp duplicate in the sample stream. Prior to June 2012 the QA/QC material was inserted for every 20 to 25 samples submitted for analysis, post June 2012 the process was changed, inserting the QA/QC samples for every 40 core samples. Drill core from a local, barren diabase dyke is used as a blank sample medium.

Prior to May 2010, ALS had been instructed to take one reject duplicate after every 25 samples processed. The sample number was tracked through the analytical process with the suffix “dup”. The method of selecting reject duplicates was further modified starting May 2010 in order to make a blind duplicate sample, where the sample would receive its own sample number sequential to the sample stream.

CRM standards for gold, individually wrapped in 60 g sealed envelopes, were prepared by Ore Research and Exploration Pty. Ltd. of 6-8 Gatwick Road, Bayswater North, Victoria, Australia (OREA) and provided by Analytical Solutions Ltd. of Toronto, Ontario. Several CRM standards are used in order to vary the expected value and depending on availability (refer to Table 11.2).

LSG retains a full time Database Administrator to review all assay data. Copies of assay certificates are either downloaded from the external lab LIMS system and/or are received via e-mail by the LSG Database Administrator and by the project’s Qualified Person. The digital assay data, in the form of “csv” files, is validated by the Geovia program, Lab Logger Version 2.0 for all assay results received from ALS. For all other analytical labs, the analytical data is placed through an Excel based filter where failure criteria for standards and blanks are entered and failures are highlighted. As of July 2014 all assay results received from Actlabs and Bell Creek Lab are processed using Lab Logger Version 2.0. The use of these software programs ensures that the results from the QA/QC samples fall within the approved limits set for the control samples.

Failures are defined as assay determinations outside of three standard deviations (3SD) from the recommended value (RV) or an assay of greater than 0.1 g/t for blank samples. A failure triggers a re-assay of all samples between the preceding and following CRM or blank using the sample pulps. Provided no repeat failures are encountered, the results of the re-assay are stored in the project database. A CRM of the same type that experiences two failures is sent to the laboratory for assaying.

Table 11.3:Bell Creek Samples (Drilling from November 2nd, 2012 to December 17th, 2014)

Laboratory	Drill Core Samples	Standards	Blanks	Coarse Duplicates	Total QA/QC Samples	Total Samples Sent (Core + QA/QC)
Accurassay Laboratories	5,512	236	239	235	710	6,222
Activation Laboratories	11,912	219	266	227	712	12,624

ALL LABS	27,490	721	791	716	2,228	29,718

The QA/QC results are reviewed by one of the QPs who have the discretion to override the re-assay protocol if there is sufficient evidence to warrant.

Reasons for a geological override include:

·If a standard or a blank fails by less than 0.05 grams per tonne as this is very close to the cut-off for a pass.

·If a standard or a blank fails by more than 0.05 grams per tonne and there are no ore grade samples, and no ore grade sample was anticipated within the area of the QC failure, the sample is overridden as it is believed that no significant assay is affected.

·Occasionally a failure is due to the wrong standard being recorded as sent or two QC samples being switched at some point in the shipping process. If this occurs and the error can be absolutely proven but corrections cannot be made the failure is overridden.

·In the situation of a standard or blank failing but the drill hole is in an area that is actively being mined or developed before a re-assay can be returned the failure is overridden.

·Any time there is a failure of a blank ore standard that does not fall into one of the criteria it can still be overridden if the qualified person believes the error is forgivable. In this case a comment stating the override is added to the database. An example of this is the QP noting that one standard was consistently failing by the same extent of an error. The error was overridden and the standard replaced in future sample shipments.

The internal QA/QC program on drill core for underground drilling was followed by LSG for the period covered by this technical report (drilling from November 2nd, 2012 to December 17th, 2014) as shown in

Technical Report, Bell Creek Mine, 27 March 2015

Table 11.4. Refer to Appendix B, “Statistical Analysis of Bell Creek Mine QA/QC Assay Data” for an internal LSG memo discussing statistics for the QA/QC on new drilling added since the last 43-101 report. In addition, LSG maintains a policy of re-assaying 5% of the pulp samples returned at a third party assaying facility as a check. Results of the check assay program are also discussed in Appendix B.

For the surface drill programs, ALS Canada was the principal lab used for drill core analysis. Issues were not identified through a review of the analytical data for the standards and blanks used in the QA/QC program. Results from the course duplicate data show good repeatability. Check assays on the surface drilling were completed by SGS Canada with good correlation against original assays from ALS Canada.

For the underground drill programs, SGS Canada Inc. was the principal lab used for drill core analysis until the end of the 1st Quarter of 2011 when a change was made to SPJ Assay Labs and then Accurassay Laboratories due to assaying costs. Some issues were observed with standards processed by SPJ. The 14 drill holes completed during this period were of an exploratory nature and do not have a noticeable impact on the resource estimate. Significant issues were not identified through a review of the analytical data for the standards and blanks used in the QA/QC program for SGS and Accurassay. Results from the course duplicate data show good repeatability. Check assays on the SGS and Accurassay results were completed by ALS Canada Ltd. with good correlation.

The author is satisfied that the procedures followed are adequate to ensure a representative determination of the metal contents of any sampled intervals in the drill core and that the results are acceptable for use in preparation of this Mineral Resource estimate.

11.3UNDERGROUND FACE CHIP, MUCK TEST HOLE SAMPLES

11.3.1Procedure for Taking Face Chip Channel Samples

Chip samples are taken across the development heading “face”, along walls and across the “back” honoring changes in rock type, alteration, vein style, vein intensity, and amounts and types of sulphides. The chip samples are designed to crosscut a sub-vertical vein, sulphide mineralized envelope, or mineralized structures situated in the central portion of the development heading at approximately 1.3 to 1.5 metres above the floor. Samples are taken from left to right across the face. Samples of mineralization have a maximum length of 0.5 metres. Each chip sample extends 0.5 metres above and 0.5 metres below the designated sample height resulting in a 1 metre wide panel. The resultant sample should weigh approximately 2 kilograms.

Technical Report, Bell Creek Mine, 27 March 2015

63

Descriptions of the samples are recorded and a photo is taken of the face illustrating the geology, mineralization, and sample panels. Samples are submitted for assay as described in the diamond drill core protocols section of this report.

For the Bell Creek deposit, chip samples are taken to aid in defining the shape and grade of the mineralized zones. Face, wall and back samples may be taken depending on the orientation and location of the zone with respect to the current face location in the ore zone. This helps in identifying any mineralized material which may need to be slashed (i.e. excavated) prior to establishing the final ore zone geometry. Chip sampling on the Bell Creek deposit generally represents the full mineralized zones as the zones are often less than the maximum 7 metre development round width (per the Bell Creek ground support policy).

11.3.2Procedure for Taking Muck Samples

Underground miners are required to take muck samples in development headings at the direction of the geology group. Samples are generally taken only from ore headings, but can be collected from waste headings if they have been properly identified as part of the round numbering system. Four muck samples are collected per 3.0 metre wide x 3.0 metre high x 2.8 metre long development round which represents approximately 75 tonnes. The muck samples taken during a shift along with the appropriately filled out sample description tags are brought up from underground and deposited in designated locations. The sample number, date, shift, workplace, employee, and comments are recorded and the information given to the geology department.

When mining from longhole stopes, the LHD operator is instructed to take a sample every 40 tonnes of muck.

All underground muck, chip and test hole samples are transported from underground directly to LSG’s Bell Creek Analytical Lab for analysis.

11.3.3Procedure for Taking Test Hole Samples

Underground miners are required to drill test holes in the walls of “ore” development rounds at the rate of one hole per wall per round. As these holes are being drilled, the drill “cuttings” are collected every two feet for four samples per hole. One part of a two part numbered tag is placed in the sample bag. The other portion of the numbered tag is labeled with round number, left or right wall, downhole interval (i.e. 0-2ft), date and miner’s name which is given to the geology department to document the test hole process. The test hole samples are transported from underground directly to LSG’s Bell Creek Analytical Lab for analysis.

11.3.4Data Management for Chips, Muck and Test Hole Samples

Chips, muck, and test holes are identified by sample tags. The information from the sample tags is entered by a trained geological technician into a “Sample Data Tracker” Excel spreadsheet, with assays being added to the “Tracker” as they are received from LSG’s Bell Creek Lab. Sample numbers are manually entered into the development round “face/wall” sheets. The Sample Data Tracker then sends out data queries which populate the development round face/wall sheets with their corresponding assay results.

12.0DATA VERIFICATION

12.1HISTORIC DATA

Historical diamond drill data was acquired by Lake Shore Gold (LSG) in the form of electronic databases (varying software format) with the accompanying hand written and/or typed diamond drill log from a range of previous claim holders. For the most part, original lab certificates and surveying records are not available. It cannot be confirmed to what extent double entry of log entries was utilized to check for typographical errors at the time of entry.

LSG has not directly conducted a check on the electronic database however, as part of the initial Mineral Resource Estimate; Scott Wilson RPA has reviewed this data set and considers it appropriate for use in the preparation of Mineral Resource estimates. The Scott Wilson review is reproduced below:

As part of data verification, Scott Wilson RPA conducted spot checking of the drill hole database. Approximately 10% of the drill holes that intersected the mineralized domain models at Bell Creek were selected for validation on a semi-random basis. In all, a total of 23 drill holes were selected for examination, with drill logs located for 19 of these holes. The original drill logs for four of the historical drill holes could not be easily located and are believed to be stored in the archived data from previous owners. The information contained in the drill logs for the 19 holes was compared against the information contained in the digital database.

The drill hole database supplied to Scott Wilson RPA is the end result of the amalgamation of older drill hole databases prepared by previous owners of the property and new drill hole information recently obtained by LSG. Given this historical context of data entry over a period spanning several decades, Scott Wilson RPA understands that the database format, coordinate system, lithologic codes, and data entry protocols for the older, vintage drill holes may not be consistent with those currently employed by LSG for the entry of new drill hole information.

The findings of the database audit, along with recommendations, are presented in Table 12.1. Many of the observations stated below are viewed by Scott Wilson RPA as housekeeping items to be addressed during the normal course of operations.

Table 12.1:Results of the Scott Wilson RPA Database Spot Check Audit

Drill Hole	Comments

General Comment	Software/data bug appears to be present in LSG drill log printing routine. Some assays in the database are not being printed out on the drill logs.
General Comment	Current LSG (?) assay procedures includes re-running samples using a Fire Assay- Gravimetric finish procedure for high-grade samples. When more than one FA- Gravimetric assay is conducted, only the first assay is included in the database.
	Recommend that the average value of all FA-Gravimetric assays be entered into the database.
General Comment	Recommend that a minimum of three cuts on pulps of “high grade” samples be analyzed by FA-Gravimetric assay methods, rather than relying on only one value.
	Assay for the sample will be the average of the three cuts.

In response to the discovery of the typographical error of the assay value in drill hole 4-9, at Scott Wilson RPA’s request, LSG carried out a program of assay validation for all samples in the drill hole database with gold values greater than 6 g/t Au. The purpose of this exercise was to conduct a high-level review of the accuracy of the higher grade assay values in the database and to conduct a search for any other typographical errors of this kind, although the identified sample is not included in the current Mineral Resource estimate. A total of 105 assay values greater than 6 g/t Au contained within assays carried out by previous owners were validated. Of these, the original assay records for only one sample could not be located. A difference of

Technical Report, Bell Creek Mine, 27 March 2015

greater than 1 g/t Au (both higher and lower) between the value entered into the database and the original assay values was discovered for only two other samples.

As a result of its data validation efforts, Scott Wilson RPA believes that the drill hole data representing the mineralization intersected by drilling at the Bell Creek deposit is appropriate for use in the preparation of Mineral Resource estimates.

12.2LAKE SHORE GOLD DATA

The data generated by all drill programs is added to the database either manually or by digital data import into the GEMS database. The following is a summary of how different data types are added to the database:

·Lithology — entered manually using Geovia’s GEMS Logger custom drill hole logging software by the logging geologist

·Collar data — imported after field pick-up by surveyor or “beat” geologist (bazooka holes)

·Downhole survey data —

·Collected while drilling — using an instrument such as the Reflex™ EZ-TRAC — manually using GEMS Logger

·Collected after drilling — using an instrument such as the Reflex™ GYRO — imported

·Assay data — imported from digital files provided by assay lab

All drill results are checked using the Validate Drill Data tool in Geovia GEMS v 6.5. Tests are run on collar co-ordinates, downhole surveys, lithology, and assay data to check for the errors listed below:

·Entries greater than hole length

·Negative Length Intervals (from and to errors)

·Zero Length Intervals

·Out of sequence intervals

·Missing Intervals (Lithology)

All errors are corrected prior to use.

Validation of the numerical values or actual data occurs on an ongoing or “in-program” basis as holes are completed, by viewing drill holes on screen using Geovia GEMS v 6.5 both in 2 and 3D modes and through printed copies of plans and sections. Any discrepancies in collar location, downhole survey data, lithology and assay data are communicated with to the Database Manager who makes the necessary changes to the database.

12.2.1Surface Drilling

All surface holes drilled by LSG between 2008 and 2012 were individually validated in a check program completed between October 2011 and March 2012. Drill logs were printed out from the database and individually edited for header, downhole surveys, geology and assays with identified errors corrected.

Technical Report, Bell Creek Mine, 27 March 2015

67

12.2.2Underground Drilling

During the “in-program” validation, only minor discrepancies in the data were noted and corrected.

Underground diamond drill holes completed since November 1st, 2012, effective date of the March 2013 technical report, were subjected to a random 5% check of data which included plotting of drill holes in plan to check for location, downhole survey and lithology errors. While reviewing this data it was noted that some information that would appear in the header page of the drill logs had not been added to the database. The missing data was collected and imported into the database by the Database Manager. No other data errors were encountered.

As a result of these data validation efforts, the author believes that the drill hole data is appropriate for use in the preparation of Mineral Resource estimates.

13.0MINERAL PROCESSING AND METALLURGICAL TESTING

13.1HISTORICAL TEST WORK

Prior to 2011, metallurgical testing on Bell Creek mineralization had not been completed by Lake Shore Gold (LSG). Reliance had been placed on historical test work conducted prior to the construction of the Bell Creek Mill and on historical milling experience.

Metallurgical testing on Bell Creek mineralization was first completed for Canamax in 1983 by Lakefield Research of Canada Ltd. (Lakefield).

Test work was conducted on four samples and included mineral characterization (head assays, emission specifics, specific gravity (SG) determination, gold occurrence test), trial grinds, flotation tests, and cyanidation of the ore. A fifth sample was used for settling and filtration tests. A representative fraction was removed from each sample and the results are presented in Table 13.1.

The following description of results is derived from Lakefield (1983).

“The occurrence of gold in each sample was determined by a sequential amalgamation, leaching procedure. The samples were ground to approximately 65% -200 mesh and amalgamated. The amalgamation tailing was leached in a cyanide solution to determine the exposed gold. The cyanidation residue was leached in hot HCl followed by a cyanide leach establishing the establishing the gold associated with carbonates and pyrrhotite. Finally the residue was leached with aqua regia determining the gold associated with other sulphides. The remaining gold was associated with silicates.

Lakefield concluded that at least one-half of the gold present in each sample was in the form of free gold and that gold extractions of 96% to 98% were achieved by direct cyanidation.

Direct cyanidation tests were conducted on all composites, except Sample LG-B, to investigate the effect of fineness of grind, retention time, pre-aeration and Pb(NO3)2 addition. All tests were performed in bottles on rolls at 33% solids. The cyanide and Ca(OH)2 concentrations were maintained at 0.5 g/L.

The fineness of grind was increased from 75% to 95% -200 mesh to examine its effect on gold extraction and reagent consumption. A six hour aeration stage preceded each cyanide leach. In the range investigated, Lakefield found that the fineness of grind had no pronounced effect on gold extraction.

Technical Report, Bell Creek Mine, 27 March 2015

69

An additional series of tests were performed to investigate the effect of retention time on gold recovery. Contact times of 12 hours to 48 hours were examined. All tests included a six hour aeration period prior to cyanidation. Increasing the retention time from 12 hours to 48 hours did not affect the recovery of gold from Sample MG-G. The cyanide consumption increased from 0.09 kg/t to 0.34 kg/t NaCN. With only 12 hours contact time the gold extraction from Sample AG-B dropped from 95% to 90 percent. Gold recovery from sample HG-A did not improve when the retention time was increased from 24 to 48 hours. Lakefield concluded that increasing the time beyond 24 hours resulted in no improvement in recovery.

Due to the presence of pyrrhotite in the samples, a six hour pre-aeration stage was added to most cyanidation tests. The effect of extending the pre-aeration to 24 hours was examined. Lakefield observed that with the exception of Sample AG-B, increasing the pre-aeration time reduced the cyanide consumption. The extraction of gold was not affected in any of the composites.

The effect of lead nitrate addition on Au extraction was investigated. All tests were conducted with a six hour pre-aeration stage and a 48 hour cyanide leach. Lakefield noted that the addition of 500 g/t Pb(NO3)2 had no significant effect on gold extraction or reagent consumption.

A procedure for flotation followed by cyanidation of the concentrate was investigated and involved grinding to 70% -200 mesh with a xanthate mixture, Aerofloat 208 and Aerofloat 25, further addition of xanthate in the rougher circuit and a water cleaning stage of the rougher concentrate. The cleaner concentrate was reground to -200 mesh, pre-aerated in lime water for 20 hours followed by a 48 hour cyanide leach maintaining 0.5 g/L NaCN and 0.5 g/L Ca(OH)2. Tests were also conducted involving a coarser grind, Na2SiO3 addition, reagent simplification and addition of a second cleaning stage. Lakefield found that although the sulphide recovery varied by 10% over this series of tests, the Au recovery remained relatively stable with 91% to 93% in the cleaner concentrate at a grind of 70% -200 mesh.

The recovery of Au in a gravity concentrate from Samples MG-B and AG-B was investigated. The samples were ground to approximately 60% -200 mesh and passed over a laboratory Wilfley table. The table concentrate was amalgamated to determine the amount of free gold. The gold recovery in the gravity concentrates was only 64% and 74% from Samples MG-B and AG-B respectively.

Settling tests were completed on samples before and after cyanidation in which the samples were ground to approx. 85% -200 mesh. Initial and final percent solids varied between 32% to 33% and 62% to 66% respectively.

Filtration characteristics of two samples were investigated in which the pulp was thickened to 53% solids and standard pour-on tests were performed using a polypropylene cloth and a 250 ml pulp sample. A cake thickness of 12 mm to 15 mm was produced with moisture between 17% and 22% and filtrate rates between 400 Lph/m2 and 1,367 Lph/m2.

The Bond Work Index of each sample was estimated by comparing the size distribution for a specific grinding time with that of an ore of known work index. The estimated Bond Work Indices varied between 7.7 and 7.9.

Complete results of the test work are documented in a report by Lakefield titled “An Investigation of the Recovery of Gold from Samples Submitted by Amax Incorporated, Progress Report No 1. Project No. LR 2686, October 5, 1983”.

Technical Report, Bell Creek Mine, 27 March 2015

70

Additional test work was completed by Lakefield for Canamax on two composite samples in 1985. A greater emphasis was placed on specific requests such as the effect of using creek water in the milling process versus tap water and post processing of effluent. Specifically, cyanide destruction test work included alkaline chlorination and SO2 aeration. Results of this test work are documented in a report by Lakefield titled “An Investigation of the Recovery of Gold from Samples Submitted by Amax Incorporated, Progress Report No 2. Project No. LR 2686, April 17, 1985”.

13.2RECENT TEST WORK

The Bell Creek Mill Phase 1 expansion was completed in October 2010. Phase 2 of the mill expansion was completed during the third quarter of 2013. Prior to launching the Phase 2 expansion project, more comprehensive test work was completed. The following companies were involved with this test work.

·G&T Metallurgical Services LTD. Kamloops, BC (G&T)

·Starkey & Associates Inc., Oakville, Ontario

·Xstrata Process Support, Falconbridge, Ontario (XPS)

·Outotec Canada Inc.

·FLSmidth Knelson, Langley, BC (Knelson)

·Joe Zhou Mineralogy

·SGS Minerals

G&T Metallurgical completed bond work index testing on ore from the Bell Creek Mine. The bond ball mill work index for this ore was 13.3 kWh/tonne. Sag mill (SMC) tests were also completed on these samples with the test data indicating that the A*b value was 29.9 which is classified as hard ore, but is only ranked in the 13th percentile for all ores in their database.

The objective of Starkey and Associates’ test work was to size a sag mill that would enable the throughput to be increased to 3,000 tonnes per day using the two existing mills. Starkey also verified that a mill (which was available on the market at the time) was suitable for 3,000 tonnes per day and also had the capability to process up to 6,000 tonnes per day. All the possible LSG ore types were used for the test work, including Bell Creek ore.

XPS used Starkey and Associates’ data and ran JKSimMet simulations of the sag circuit with tonnage set at 250 tonnes per hour and using the hardest of the four materials. These results were used to establish the best operating conditions and obtain circulating load, pulp density, cyclone feed, and cyclone overflow data which were used to help suppliers in the sizing of the cyclones.

Outotec tested the material types for settling characteristics to size a new high efficiency thickener rated for 6,000 tonnes per day.

Knelson tested the Bell Creek material to establish data points for gravity recoverable gold (GRG). Bell Creek ore GRG was 38.9% which classifies the gold grains as moderate size. This information is being used as the basis for increasing the efficiency of the gravity circuit.

Joe Zhou Mineralogy was contracted to do some diagnostic leaching tests on two samples of mill tailings to determine the speciation of the tails gold. It showed that 94% of the gold was locked in other minerals.

Technical Report, Bell Creek Mine, 27 March 2015

71

SGS Minerals was contacted to determine the influence of grind on recovery. The results show that as with most gold ores there are measurable reductions in recovery by grinding coarser than the mill currently does.

Overall, the combination of LSG’s operating history and the extensive amount of test work conducted provides confidence that the process design and equipment selection will result in achieving the targeted recovery and throughput levels.

14.0MINERAL RESOURCE ESTIMATES

14.1SUMMARY

Lake Shore Gold (LSG) has prepared an updated Resource Estimate for the Bell Creek Mine with an effective date of December 31, 2014. The report updates the Bell Creek Mine Resources as reported in the National Instrument 43-101 Technical Report, Resource Estimate Update and Prefeasibility Study and Mineral Reserve Estimate for Bell Creek Mine, Hoyle Township, Timmins, Ontario, Canada, dated March 28, 2013.

The estimate is based on both historic diamond drilling and drilling completed by LSG. A total of 938 drill holes were used in the estimate including 119 historic surface and underground holes, and 819 surface and underground drill holes completed by LSG.

The Mineral Resource for the Bell Creek Mine occurs within sixteen mineralized domains of which four, the North A, North A2, North B and North B2, account for 91% of the total ounce content. The bulk of this mineralization is centered about section 5950 E between 975 metre elevation and 1375 metre elevation.

The resource totals 4.90 Mt at 4.36 g/t Au amounting to 686,700 ounces of gold in the Measured and Indicated category and 4.40 Mt at 4.84 g/t Au amounting to 685,000 ounces of gold in the Inferred category. The resource was estimated using Inverse Distance to the power 2 (ID2) interpolation method with gold assays capped to 44 g/t for the North A vein, and 34 g/t for all other domains excepting the hangingwall veins which were capped to 25 gpt. The base case estimate assumes a cut-off grade of 2.2 g/t Au with no allowance for dilution.

Table 14.1:Total Resources — Bell Creek Mine

Category	Tonnes	Capped Grade (g/t Au)	Capped Ounces Au
Measured	331,000	5.25	55,900
Indicated	4,573,000	4.29	630,800
Measured and Indicated	4,904,000	4.36	686,700
Inferred	4,399,000	4.84	685,000

Notes

1.The effective date of this report is December 31, 2014.

2.The mineral resource estimates have been classified according to CIM Definitions and Guidelines.

3.Mineral resources are reported inclusive of reserves.

4.Mineral resources incorporate a minimum cut-off grade of 2.2 grams per tonne for the Bell Creek Mine which includes dilution to maintain zone continuity.

5.Cut-off grade is determined using a weighted average gold price of US$1,100 per ounce and an exchange rate of 0.90 $US/$CAD.

6.Cut-off grade assumes mining and G&A costs of up to $77 per tonne and/or processing costs of $22 per tonne and assumed metallurgical recovery of 94.5%.

7.Mineral resources have been estimated using the Inverse Distance Squared estimation method and gold grades which have been capped between 25 and 44 grams per tonne based on statistical analysis of data in each zone.

8.Assumed minimum mining width is two metres.

Technical Report, Bell Creek Mine, 28 March 2013

73

9.The mineral resources were prepared under the supervision of, and verified by, Eric Kallio, P. Geo., Senior Vice-President, Exploration, Lake Shore Gold Corp., who is a qualified person under NI 43-101 and an employee of LSG.

10.Tonnes information is rounded to the nearest thousand and gold ounces to the nearest one hundred, as a result totals may not add exactly due to rounding.

14.2CONSTRAINTS AND ASSUMPTIONS

The following general constraints and assumptions were used in creating the block model Mineral Resource estimate for the Bell Creek Mine:

·The locked down date for the inclusion of diamond drill or development data is December 17, 2014.

·All work associated with the estimate, database compilation and verification, geologic modeling, and grade interpolation is completed using Geovia GEMS v 6.5 geological modeling software.

·Geological interpretation and definition of mineralized domains is defined using diamond drill results in conjunction with underground mapping and sampling.

·It is assumed the general orientations or relationships of mineralized domains delineated through underground development do not fundamentally change at depth.

·Only diamond drill assay information is used in grade interpolation, (chip and muck sample results are not used).

14.3DATABASE

The database used for the current resource estimate is a Geovia GEMS (Microsoft SQL) database comprising historic drill data (drilling prior to LSG acquisition of the Bell Creek Property) as well as drilling completed by LSG both from surface and underground. The GEMS database consists of tables including header, survey, lithology, and assay data with pertinent fields summarized in Table 14.2. Additional fields within the above tables are currently being utilized by LSG for logging of the drill core or final resource estimation.

The following validation steps were taken to ensure the integrity of the database:

1.Plotting of plans and sections to check for location, elevation, and downhole survey errors.

2.Test for missing intervals, overlaps and out of sequence intervals within survey, assay, and lithology tables using the GEMS validation tools.

3.Thorough review of all historical data available to ensure assay and survey (collar and downhole) information are properly presented in the database.

4.Random validation of 5% of the assay and lithology data against drill logs and assay certificates. (This was completed for drilling since the last resource update only as data from earlier drilling has already been subjected to this check).

Only minor discrepancies were noted and corrected prior to the estimation of the resources. None of the errors detected would have a significant impact on the Mineral Resource estimate. The database, in the writer’s opinion, is appropriate for the estimation of resources.

14.4DOMAIN MODELS

Mineralized domains were established through the projection down plunge of mineralization historically exploited at the Bell Creek Mine or exposed in recent level development by LSG in conjunction with diamond drill results.

A total of sixteen mineralized domains are recognized of which five are defined by diamond drill results alone.

On strike and down plunge extent of the domains varies. The North A and North B are the most continuous with strike lengths of 500 metres and down plunge length of 1,720 metres, (1,680 metre vertical). Both veins remain open down plunge. The western limit of the domain models has been set as the eastern contact of a north-south striking diabase dike. Additional gold mineralization is known to be present west of the dike, however the focus of exploration to date has been east of this dike. A summary of the domains is provided in Table 14.3.

Criteria and process used to create these mineralized domains are outlined below:

·Interpretation was completed on North-South sections. A section spacing of 6.25 m was used for the bulk of the veining above the 1400 m elevation but was increased to 12.5 m in areas of reduced drilling. Below the 1400 m elevation a section spacing of 12.5 m was used. This was increased to 25 m east of 6075 E.

·Underground development including mapping was used to aid interpretation.

·Mineralized domains were based on a combination of grade, alteration (albite/ankerite), sulphide content and quartz content. Where low gold grades were observed a minimum inclusion grade of 2.2 gpt was applied.

·A minimum horizontal width of 2 metres was used.

·Mineralized domains were restricted to the mafic volcanic units only.

·Domain solids were created from the tied polylines and checked for errors and overlaps with nearby domains. Each is stored in GEMS in BT2 format.

·Points on each polyline are snapped to the exact drill hole location in three dimensions.

Longitudinal and oblique views of the mineralized domains are presented in Figure 14.1 and Figure 14.2.

14.5SPECIFIC GRAVITY

Specific gravity (“SG”) was determined on 236 samples of mineralization selected from surface diamond drill holes targeting the Bell Creek North A and North B zones. Specific gravity measurements were completed at the LSG exploration office utilizing the conventional water displacement approach. At the time of sample selection it was not possible to assign mineralization to a specific mineralized domain.

An average SG of 2.82 has been selected as representative of all mineralized domains and has been used for resource estimation.

Ultramafic Volcanics	—	28	2.82	2.82
Sediments	—	29	2.76	2.82	*

* No mineralization is hosted in sediments.

14.6GRADE CAPPING

An evaluation of assay grade distribution was completed for each mineralized domain and a grade capping value determined. Assay grades exceeding the grade capping value were reset to this limit.

All samples contained within the sixteen domain solids were uniquely coded in the diamond drill database and extracted for analysis. The descriptive statistics of the extracted sample data sets are presented in Table 14.5.

Normal, Log-Normal histograms and probability plots were generated for each domain. Grade caps were selected at break points in the slope of the probability plots. Domains with few data points were evaluated grouped with domains which exhibit similar mineralization and orientations.

Final capping limits for grouped domains were applied to the raw assay grade and were set as follows:

·North A44 g/t

·North A Splay veins34 g/t

·All other North A domains34 g/t

·All North B domains34 g/t

·All Hangingwall domains25 g/t

The log normal populations and probability plots for these domain groups are provided in Figure 14.3 through Figure 14.7.

14.7ASSAY COMPOSITING

Samples within the sixteen domains were composited by fixed-length using an option within GEMS 6.5 that adjusts composite length to ensure all composite intervals in a given drill hole are of equal length. By comparison, the traditional method of applying a constant composite length along the drill hole intersection may result in the last composite of an intersection being of shorter length. This method has not been used due to the possibility of introducing a grade bias should footwall grades vary from grade across the drill hole intersection.

Only samples from within a mineralized domain were used to create composites for the domain and each composite was flagged with the unique numeric code for said domain. Average sample length prior to compositing is 0.59 metres with 96% of samples being 1 metre in length or less. Nominal composite length prior to adjusting for short length composites is 1 metre.

14.8VARIOGRAPHY

14.8.1Trend Analysis

Initial evaluation of grade trends was conducted through examination of the dimensions of historical mine workings and drilling. Prior mining activity was centered on the North A and is evident as a continuous series of shrinkage or longhole stopes between the 60L and 370L. The portions of the North A consistently exhibiting grades in excess of 3 g/t average 200 metre in strike and 350 metres down dip yielding a dip to strike ratio of 1.75.

To verify grade trends outside the mined out areas a grade trend model was constructed. For this exercise, a data file was prepared that contained the average gold grade across the entire width of the mineralized zone for each drill hole that pierced each of the eight domain models. Gold grades were then interpolated using a spherical search of 80 metre radius. Results were then viewed as vertical longitudinal projections.

Gold mineralization for the North A, North A2, North B, and North B2 domains plunge steeply (70 degrees) to the east within the steeply south dipping veins. Within this larger trend sub-zones of higher grades are suggested in areas with higher drill hole density. These sub-zones plunge 60 to 70 degrees to the west, and may represent the intersection lineation of two mineralizing structures, dilation flexures, or the influence of a yet unrecognized structural control on the gold distribution. This geometry matches the present understanding of mineralization trends based upon underground development.

This evaluation was intended to assist in the construction of variograms only. No evaluation or reporting of the grade and tonnages interpolated was undertaken.

An example of results for the North A are presented in Figure 14.8.

Technical Report, Bell Creek Mine, 27 March 2013

Figure 14.8:Grade Trend Model — North A Domain

14.8.2Variograms

Downhole and omnidirectional variograms were constructed using the capped, equal length composited sample data for the North A domain. Efforts to identify the anisotropies associated with the smaller domains were not successful due to the limited number of data pairs.

The evaluation of anisotropies present in the data are in line with the observed local trend. A spherical model can be fitted showing ranges for the first and second structures in the order of 30 to 40 m down plunge.

A summary of the variographic parameters derived for the North A is presented in Table 14.8.

14.9BLOCK MODEL

14.9.1Block Parameters

An upright, non-rotated, partial percentage block model was constructed using the GEMS v.6.5 software package. [i.e. The long axis of the blocks is oriented along an azimuth of 090º and dips vertically (i.e. -90º)]. The percentage of any block that is contained within the domain model is used to weight the volume and tonnage of each block.]. The selected block sizes are 2 metres x 3 metres x 3 metres (width, length, height). Block model limits are summarized in Table 14.9.

Several attributes were created to store information such as metal grades, the number of informing samples, average distances, domain codes, resource classification codes, and claim owners. These attributes are summarized in Table 14.10.

*Only the AU_CUT grades have been used to define resources. AU_UNCUT and AU_NN were generated for comparison only. All attributes related to estimation (AVG_DIST, NSAMP_USED, etc) are derived from the AU_CUT interpolation.

Sub-blocking is not available in GEMS software. Domain solids are used to flag individual blocks as to rock type (domain), and percentage of the block that is within the domain. For reporting purposes volumes are obtained from the domain solid with corresponding grades obtained from the block model.

14.9.2Grade Interpolation

Gold grades were interpolated into the individual blocks for the mineralized domains using inverse distance squared (ID2). A three pass approach was used with the search ellipse oriented along the dominant mineralization trend.

“Hard” domain boundaries were used along the contacts of each mineralized domain. Only drill hole composites contained within the respective domain were allowed to be used to estimate the grades of the blocks within the domain. Only blocks within the domain limits were allowed to receive grade estimates.

Uncapped grade as well as a capped nearest neighbor interpolations were generated for comparison purposes. Only the estimate based on capped, composited grades (AU_CUT) has been used to outline resources.

14.9.3Validation

Plans and sections were cut through the block model and resource solids to visually compare the block grades to the original diamond drill data. The grade and distribution of the block grade is consistent with drill hole assay data and the understanding of grade distribution trends. A typical section through the Bell Creek block model showing grade blocks and original drill data is illustrated in Figure 14.9. A typical plan view is shown in Figure 14.10.

(Not a resource — No cut-off applied and no mined out blocks removed)

A comparison of stope production reported from the block model to the Mill Reconciled production has been completed for stopes mined during the 2014 calendar year. The comparison indicates some large variations for individual stopes with an overall variance of less than 10% each in terms of tonnage and grade and less than 5% in terms of ounce content. When 5% dilution is added to the overall block model tonnage mined in 2014 in order to match the Mill Reconciled tonnage the grade variance drops to 5 percent.

Technical Report, Bell Creek Mine, 27 March 2013

In addition a cavity monitoring survey program has been initiated although insufficient stopes have been surveyed to date to allow a valid comparison to be completed.

SGS Canada Inc. — Geostat (“SGS Geostat”) was mandated by Lake Shore Gold to complete a review of the mineral resource estimate completed internally by LSG. The verification included the following points.

1.Summary review of the database.

2.Review of the solids and the limits of the domains with possible risk associated with the limits.

3.Review of the compositing process and capping levels

4.Review of the interpolation process and its statistical components.

5.Kriging of the most important (in Au ounces) zones with the possible estimation errors associated with the interpolation and composites.

6.Review and comments on the Measured category classification.

7.Review of the reported resources tables.

SGS Geostat agrees with the mineral estimates for the deposit. No major discrepancies are observed in the database, mineral solids, capping levels, composites, block model interpolation and reports. The Mineral Resource estimates conducted by LSG are correct and done accordingly with the Industry’s Best Practices and Standards. (Jean-Philippe Paiement, M.Sc., SGS Canada — Geostat, Feb 18, 2015.)

Notes

1.The effective date of this report is December 31, 2014.

2.The mineral resource estimates have been classified according to CIM Definitions and Guidelines.

3.Mineral resources are reported inclusive of reserves.

4.Mineral resources incorporate a minimum cut-off grade of 2.2 grams per tonne for the Bell Creek Mine which includes dilution to maintain zone continuity.

5.Cut-off grade is determined using a weighted average gold price of US$1,100 per ounce and an exchange rate of 0.90 $US/$CAD.

6.Cut-off grade assumes mining and G&A costs of up to $77 per tonne and/or processing costs of $22 per tonne and assumed metallurgical recovery of 94.5%.

7.Mineral resources have been estimated using the Inverse Distance Squared estimation method and gold grades which have been capped between 25 and 44 grams per tonne based on statistical analysis of data in each zone.

8.Assumed minimum mining width is two metres.

9.The mineral resources were prepared under the supervision of, and verified by, Eric Kallio, P. Geo., Senior Vice-President, Exploration, Lake Shore Gold Corp., who is a qualified person under NI 43-101 and an employee of LSG.

10.Tonnes information is rounded to the nearest thousand and gold ounces to the nearest one hundred, as a result totals may not add exactly due to rounding.

These totals are based on contiguous blocks above a 2.2 g/t cut-off and have been adjusted for development and stoping carried out prior to the effective date.

The Bell Creek Mineral Resources are subject to four separate royalty agreements (Enermark, Gold Corp 1, Gold Corp 2 and Schumacher). A tabulation of the Mineral Resources by royalty holder is presented in Table 14.14 and the spatial distribution of the resources relative to the royalty claims is displayed in Figure 14.11.

It can be seen that a very small amount of tonnes are located on the Gold Corp 2 royalty claim, which historically has been recognized as forming part of the Marlhill property. Given the relatively minor quantity of tonnage located on this royalty claim, this portion of the Mineral Resource is considered as forming part of the Bell Creek deposit for the purposes of this Technical Report.

14.10.2Procedure

Resources at the Bell Creek Deposit are reported as un-mined blocks within the vein solids above a 2.2 g/t cut-off.

Three dimensional solids of all mine workings were created and blocks located within these were flagged as mined out using the MINED variable in the block model. Grades and density for these blocks were reset to zero. Remaining blocks above cut-off grade were displayed over top of drill hole composites in order to identify areas where grades above cut-off stem from a single high grade drill intersection and there is no reasonable expectation these could be economically exploited. These blocks were reset to zero grade.

The cut-off grade of 2.2 g/t was selected at the time the Bell Creek project was initiated and represents the anticipated break even grade given existing infrastructure, anticipated costs, historical metallurgic recovery and assumed metal prices and exchange rates. These parameters are not intended for use in mine planning and scheduling, or the preparation of cash flow models. This cut-off grade may be subject to change given fluctuating metal price, exchange rates, or changes in infrastructure or costs.

Determination of an appropriate cut-off grade for the reporting of reserves is outlined in Item 15.

Technical Report, Bell Creek Mine, 27 March 2013

14.10.3Classification

Resource classification is based on a combination of diamond drill hole density and proximity to underground development. In this process outlines enclosing blocks meeting the minimum requirement were digitized and used to clip this volume from the domain solids. The resulting resource category solid was then used to flag blocks within the solid as measured, indicated, or inferred.

Criteria used were as follows:

·Measured — contiguous blocks within the North A vein that have a maximum radius to the nearest drill intersection of 12.5 metres or those blocks within the North A vein that are supported by level development on 15 m spacing (solid to solid).

·Indicated — contiguous blocks within any vein that have a maximum radius to nearest drill intersection of 25 metres

·Inferred — all other estimated blocks

Figure 14.12 illustrates the resource categorization for the North A vein.

Notes

1.The effective date of this report is December 31, 2014.

2.The mineral resource estimates have been classified according to CIM Definitions and Guidelines.

3.Mineral resources are reported inclusive of reserves.

4.Mineral resources incorporate a minimum cut-off grade of 2.2 grams per tonne for the Bell Creek Mine which includes dilution to maintain zone continuity.

Technical Report, Bell Creek Mine, 27 March 2013

98

5.Cut-off grade is determined using a weighted average gold price of US$1,100 per ounce and an exchange rate of 0.90 $US/$CAD.

6.Cut-off grade assumes mining and G&A costs of up to $77 per tonne and/or processing costs of $22 per tonne and assumed metallurgical recovery of 94.5%.

7.Mineral resources have been estimated using the Inverse Distance Squared estimation method and gold grades which have been capped between 25 and 44 grams per tonne based on statistical analysis of data in each zone.

8.Assumed minimum mining width is two metres.

9.The mineral resources were prepared under the supervision of, and verified by, Eric Kallio, P. Geo., Senior Vice-President, Exploration, Lake Shore Gold Corp., who is a qualified person under NI 43-101 and an employee of LSG.

10.Tonnes information is rounded to the nearest thousand and gold ounces to the nearest one hundred, as a result totals may not add exactly due to rounding.

14.10.4Sensitivity

Sensitivities to cut-off were run at 0.5 g/t Au increments from 1.0 g/t Au to 6.0g/t Au for unclassified resources and are summarized in Figure 14.13.

14.11ADDITIONAL INFORMATION

Subsequent to the closing of the database on December 17, 2014, additional assays were received for 29 holes drilled from underground on the Bell Creek Property. Three drill holes were abandoned due to downhole deviation or ground conditions. Assays from 11 underground drill holes remain pending (effective date of this statement is March 2, 2015).

The newly received drill results confirm the geologic interpretation and grade trends evident in the block model and would not materially affect this estimate. A summary of drill results is provided in Table 14.16.

Technical Report, Bell Creek Mine, 27 March 2013

100

The Bell Creek Resource is situated on Patented Mining claims and is fully permitted. Mining activity has been ongoing within the region (Porcupine Gold Camp and within the municipal jurisdiction of the city of Timmins) in excess of 100 years and has received the favorable support of the population base and governmental institutions. The risk of negative impact stemming from permitting, environmental, political, taxation, or socio-economic issues is considered minimal. The resource is subject to royalty payments as outlined in Item 4.3. These payments have been considered when determining cut-off grades.

It should be noted that the resource would be negatively impacted by the effects of falling metal prices, or rising costs due to increased labour rates, cost of fuel, or electricity, etc.

15.0MINERAL RESERVE ESTIMATES

The proven and probable reserves estimated for the Bell Creek Mine have been based on the measured and indicated resource material included in the Resource Block Model prepared by Lake Shore Gold (LSG) Geology staff.

A mine design was completed to reflect the most likely mining and production scenario for extracting the measured and indicated resource between 445L and 1165L. The mine design considers existing surface and underground infrastructure, and includes all additional development and construction required to access the resources. The mine design includes the equipment, labour, and services required to extract the ore using a combination of development and Longhole Stoping (described in Item 16). The Longhole Stoping mining method is currently used successfully at Bell Creek Mine, and the operation has the experienced personnel and suitable equipment to continue with this method.

The Bell Creek Mine is currently operating and has existing surface and underground infrastructure in place. Sustaining capital and maintenance costs have been included to ensure the infrastructure remains in good condition for the life-of-mine. The existing management, staff, and hourly personnel will continue to operate the mine with minimal annual adjustments to staffing levels (as certain activities increase or decrease). The mine has all required permits in place.

Ore will be processed at the existing Bell Creek Mill, located on site. The mill currently processes Bell Creek ore and milling does not pose a risk to the reserves.

15.1RESERVE ESTIMATE

A 3.0 gram per tonne block model cut-off grade was used as an initial starting point to identify mining areas that require evaluation for potential mining. Table 15.1 shows the assumptions made to establish the initial block model in-situ cut-off grade.

Table 15.1:Assumptions for Initial Block Model In-Situ Cut-Off Grade

15.1.1Stope Shapes and Mining Plan

Based on the in-situ measured and indicated resource included in the Bell Creek block model, the following methodology was used to estimate the reserves.

1.The block model was reviewed in plan and in section to identify measured and indicated resource above the cut-off grade, and to confirm the applicability of the longitudinal longhole

mining method. Some of the resource material remains in sill pillars left in previous mining areas, while the majority of Indicated material lies in recently developed and currently undeveloped areas.

2.Sublevels were designed at 15 and 20 metre vertical intervals, and vertical sections were cut through the model along strike. On each vertical section, mining shapes were designed for each zone for each sublevel interval. The mining shapes were joined with adjacent sections to generate stope wireframes. A 2.4 metre minimum mining width was considered in the stope design. Note that there are some “blocks” higher than the cut-off grade that are in the block model, but are not included in stope wireframes. These are generally random blocks that are distant from planned mining areas and cannot be economically mined.

3.The in-situ tonnes and grade within each stope wireframe was extracted from the block model measured and indicated resource data. The in-situ tonnes and grade includes the planned dilution.

4.The unplanned dilution was estimated for each stope based on the stope size and geometry.

·The total stope volume was determined from the stope wireframe.

·The stope hangingwall and footwall area was calculated from the stope dimensions.

·The unplanned dilution from the hangingwall and footwall was estimated based on the dip of the stope using the criteria in Table 15.2.

·Backfill dilution from the floor (0.5 metres) and the adjacent stope endwall (0.3 to 0.4 metres) was estimated based on the floor and endwall dimensions.

Table 15.2:Hangingwall and Footwall Dilution Criteria

	Dip	Dip	Dip	Dip
Item	50-60°	60-70°	70-80°	80-90°
Hangingwall Dilution	0.45m	0.40m	0.30m	0.20m
Footwall Dilution	0.45m	0.40m	0.30m	0.20m

5.A 95% Mining Recovery factor was applied to the diluted resource for each stope.

6.The resulting diluted and recovered resource for each stope was reviewed. Diluted and recovered stopes above cut-off were included in the mine plan. Stopes below cut-off were re-designed to optimize the wireframe by reducing the stope size, or including a portion of the adjacent stope.

7.The sill development was removed from the stope resource and the development tonnes and grade distributed based on the development schedule.

8.A mine design was prepared for the identified resource, and schedule and costs applied to determine the overall economics.

From the mine plan, incremental, marginal, and overall mine economic cut-off grades were determined and used to finalize the estimated reserves. The incremental, marginal, and overall mine economic COGs are summarized in Table 15.3.

Table 15.3:Incremental, Marginal, and Overall Mine Economic COG

Item	Value
Mine Operating and Site General Costs	$77.0 / tonne
Mill Operating Cost	$22.0 / tonne
Mill Recovery	94.5%
Gold Price ($US)	$1,100

Overall Mine Economic Cut-Off Grade	4.2 g/t

A development schedule, production profile, and mine design has been completed to estimate the capital and operating costs required to access, develop, and extract the Bell Creek Mine proven and probable reserves. When evaluating sublevels and stoping blocks, overall economics were considered including factoring in a risk free rate of return and profitability. A life-of-mine cash flow analysis has been completed to demonstrate that the proven and probable reserves support the operating costs and sustaining capital expenditures. The stope wireframes, LOM plan, economics, and estimated reserves have been reviewed by a third party mining consultant. Additional details regarding the mine design, dilution and recovery, and mine operations are included in Item 16.

The diluted and recovered resource was estimated for each stope included in the mining plan. The estimated proven and probable reserves that have been included in the Bell Creek Mine plan are summarized by sublevel in Table 15.4.

16.0MINING METHODS

Overview

The Bell Creek Mine design has been based on the Resource Block Model prepared by Lake Shore Gold (LSG) geology staff. The mine design considers resource in the measured and indicated category between the 445L and 1165L. Engineering and cost assessment work has been completed on this measured and indicated resource material. The designs and cost estimates consider existing surface and underground infrastructure, mining methods, and operating experience at the Bell Creek Mine to support the updated proven and probable reserves for the property.

The naming convention for underground sublevels at the Bell Creek Mine is expressed in metres below the existing mine shaft collar (i.e. 775L is nominally 775 metres below surface).

The measured and indicated mineralized resource between 445L and 1165L consists of nine steeply dipping narrow zones. The zones strike nominally east-west with varying strike lengths. The geometry of the zones is shown in section in Figure 16.1, Figure 16.2 and in plan at 835L in Figure 16.3.

Mining experience at Bell Creek Mine has demonstrated narrow vein longitudinal longhole as a suitable and preferred mining method. The existing mine operations personnel, and local supply/support industry are experienced with this mining method and the equipment fleet will be appropriate for continued production. The mine has existing surface and underground infrastructure in place to continue to support development and production levels that were achieved by LSG in recent years. As mining progresses deeper, areas with increased resource thickness will be encountered (nominally between 950L and 1165L) which will promote an increased production rate.

The existing surface infrastructure at the Bell Creek Mine is shown in Figure 16.4 and includes:

·Access roads and site grading.

·Security gate house.

·Shaft headframe, collar house, and hoisting plant (currently not in operation).

·Compressed air plant.

·Process water supply.

·Portal and main ramp to underground.

·Electrical services infrastructure and distribution.

·Main fresh air ventilation fans and mine air heaters.

·Administration, mine dry, and training facilities.

·Warehouse and maintenance facilities.

16.1PRIMARY / SECONDARY ACCESS

The primary access to the mine will continue to be via the existing portal and main ramp from surface. The main ramp is 5 metres wide x 5 metres high and currently extends to the 790L. All active production levels in the mine will be accessed via the ramp (i.e. no captive levels) and personnel, materials, and ore and waste rock will be transferred via the ramp.

Technical Report, Bell Creek Mine, 27 March 2015

109

Secondary access/egress to/from the underground to surface will be via the existing manway in the shaft. Below the existing access to the shaft at the 240L station, the main ramp and internal raises equipped with escapeways will provide two access routes to the 240L.

16.2SHAFT AND HOISTING FACILITIES

The existing shaft is a 6.3 metre by 2.6 metre rectangular, three-compartment timbered shaft. The shaft collar is at 2,288 metre elevation and the shaft bottom at 1,998 metre elevation (290 metres deep). A main shaft station exists at the 240L. The headframe and hoisting facilities remain in place but are currently not being used. There are no plans to recondition/refurbish or deepen the shaft for production use for the reserves. Regular shaft manway inspections will continue to maintain second egress. There are existing compressed air (152 mm) and dewatering piping (203 mm) and electrical cables in the shaft that feed the 120L and 240L Pump Stations.

16.3STOPING METHODS

Narrow Vein Longitudinal Longhole with delayed unconsolidated rock fill (Longhole) stoping has been the primary mining method used to date at the Bell Creek Mine. Longhole is a widely used and proven mining method that involves common industry equipment and labour skill sets.

In current active mining areas, sublevels have been established at 15 to 20 metre vertical intervals (floor to floor) and this sublevel spacing will be maintained for remaining sublevels to the 1165L. On each sublevel, the resource will generally be accessed near the centre (along strike) and stope undercut and overcut sills developed to the east and west extents. Stope lengths will generally be 20 metres along strike; however, stopes abutting waste or low grade material may be marginally longer or shorter to optimize recovery. Longitudinal mining will retreat from the furthest stope from the access, toward the initial access point.

The resource will be mined “top down” in blocks as ramp development advances to 1165L. To maintain steady production rates, a mining front will generally be established at every third sublevel (i.e. 45 to 60 metre high blocks). Where a stope will be mined up to a previously mined stope in the block above, sill pillar recovery will be required. Sill pillar recovery will require working on top of backfill and mining uppers stopes, leaving a permanent sill pillar (1:1.25 pillar width to pillar height ratio) in place below the stope above to contain the unconsolidated rock fill. The uppers stopes will not be backfilled, and 3 metre thick rib pillars will be left to support the hangingwall (and footwall) between stopes.

The mining method is shown in the longitudinal and section view sketches in Figure 16.6.

Technical Report, Bell Creek Mine, 27 March 2015

110

Figure 16.6:Longitudinal Longhole Mining Method

16.3.1Stope Undercut and Overcut Development

Ore sills (stope overcuts and undercuts) will be developed along the strike of each zone under geological control (i.e. under the direction of mine geologists). Ore widths will generally average 3 to 4 metres and the entire sill from the hangingwall to footwall contacts will be developed. Where ore widths exceed 8 metres, the hangingwall contact will be followed, with crosscuts developed at preset intervals to expose the footwall contact.

16.3.2Secondary Ground Support

Cable bolts will be installed to help reduce dilution in areas where the stope undercut sill has “notched” the hangingwall, causing potential instability. Preliminary cable bolt design considers rings of four 6 metre long cables fanned from the stope undercut sill. Cable bolt ring spacing will be 2 metres. An allowance for five cable bolt rings per stope has been included in the cost estimate.

A pneumatic powered top hammer longhole drill will be used to drill the cable bolt holes. Cable bolts will be installed manually and grouted with a portable grout pump. A drilling contractor currently completes all cable bolt drilling and installation at Bell Creek Mine. LSG plans to replace the contractor with LSG company personnel starting in 2015.

Technical Report, Bell Creek Mine, 27 March 2015

111

16.3.3Production Drilling

Longholes will be 63.5 mm (2.5 inch) diameter and drilled with a pneumatically powered top hammer drill. Longholes will be drilled down from the overcut sill with some holes breaking through into the undercut, and others fanned as required to contour the stope limits. The drill pattern will include a 1.2 metre ring burden with 1.5 metre spacing between ring holes. A drop raise will be drilled and blasted to create the initial void for production blasting (for a series of stopes along strike). The estimated production drilling factor (excluding drop raises) will be 3 tonnes per metre of longhole. A drilling contractor currently completes all production drilling and blasting work at the Bell Creek Mine. LSG plans to replace the contractor with LSG company personnel starting in 2015. Blind uppers (i.e. non-breakthrough) drilling will be used to recover the sill pillars, with inverse drop raises used to establish the initial void for blasting.

16.3.4Production Blasting

Longholes will be loaded with emulsion explosives and detonated with non-electric blasting caps and boosters. Emulsion storage bins and the portable pump unit will be moved to and from workplaces using a service LHD equipped with forks. Including the drop raise, stope loading and blasting will require approximately three days and will be completed by LSG personnel.

16.3.5Stope Mucking

Broken ore will primarily be extracted from stopes using 2.0 to 3.5 cubic yard (3.5yd) class LHDs. When the stope drawpoint brow is closed with muck, the LHD will be operated manually (i.e. with the operator in the seat). When the drawpoint brow is open, the LHD will be operated via remote control with the operator located a safe distance from the stope and away from the moving LHD. The LHD will tram to a remuck near the level access. Ore dumped into a remuck will subsequently be remucked by a 6yd class LHD and loaded into 40 or 50 tonne class haul truck and hauled to the surface ore pad.

The production LHD will muck for 12 hours per day (including operator delays, 85% mechanical availability, and 85% drawpoint availability).

16.3.6Ore Rehandling and Underground Truck Haul

Broken ore is rehandled from a remuck with a 6yd LHD and is currently loaded into Atlas Copco MT42 trucks for hauling to surface. Due to the relatively low specific gravity of broken ore, the truck payload will be approximately 35 tonnes. There are plans and budget to purchase five new 50 tonne class underground haul trucks to accommodate the increased haul distance as mining progresses deeper.

16.3.7Backfill

Stopes will be backfilled with unconsolidated waste rock. The backfilling practice at Bell Creek Mine includes backfilling stopes until full, then extracting sufficient fill to open the brow to create the initial void (slot) for blasting the adjacent (next) stope along strike. Waste rock generated from development activities will be the primary source of backfill. Waste rock from development and raising activities will be loaded into trucks and hauled to the backfilling sublevel, and dumped into a remuck. A 2 or 3.5yd LHD will remuck the waste rock from the remuck to the stope.

Technical Report, Bell Creek Mine, 27 March 2015

112

There will not be sufficient waste rock generated from development activities to meet all backfilling requirements. Stockpiled waste rock from surface will backhauled underground in the 42 tonne haul trucks.

16.4DEVELOPMENT

There will be four development crews (one ramp crew and three sublevel development crews) operating in 2015 through 2018. A ramp crew will complete the ramp development to 1165L and establish the initial infrastructure on each sublevel (generally the larger development headings). Three sill development crews will complete the accesses to the zones and ore and waste sill development along strike. The estimated development quantities are summarized in Table 16.1.

Table 16.1:Estimated Development Metres

Item	Total (metres)
Ramp	4,306
Capital Infrastructure Waste	2,340
Operating Waste	7,503
Subtotal Waste Development	14,149
Operating Sill Ore	13,427
Subtotal Ore Development	13,427
Total Development	27,576

16.4.1Ramp and Infrastructure Development

The ramp will be developed 5 metres wide x 5 metres high at a maximum gradient of 15 percent. The ramp development crew will prioritize the ramp face, with development to establish initial infrastructure on the previous sublevel as a secondary heading. The ramp development crew advance rate will be 6.0 metres per day when including remucks, establishing initial infrastructure on sublevels, safety bays, etc. The ramp floor will include a layer of ballast material and the roadway will be maintained by a grader to help reduce equipment maintenance requirements.

The main access to sublevels will be developed 5 metres wide x 5 metres high to accommodate haul trucks. Ancillary development such as electrical substations will be developed off the level access and will have dimensions to suit the purpose or to accommodate the size of the development gear. The infrastructure on sublevels will generally include:

·Sublevel access drift.

·Sump.

·Electrical cut-out (load centres, starters, communications, etc.).

·Remucks and truck turning/loading areas.

·Material storage bays (on some levels).

·Ore sill accesses.

·Fresh air raise access drives.

·Escapeway access drives (on some levels).

·Refuge Stations (on some levels).

Technical Report, Bell Creek Mine, 27 March 2015

113

There will be one ramp and infrastructure development crew per shift. The crew will consist of a lead miner and two development miners. The equipment used by the ramp crew will include a 2-boom jumbo, 6yd LHD, and a scissor lift. The development crew will drill and blast, muck to a remuck, and install ground support using stopers/jacklegs from the scissor lift deck. The crew will install ventilation and piping services and will remuck waste into a 36 or 42 tonne capacity haul truck. A fourth worker (haul truck operator) will haul the waste rock to another sublevel and dump into a remuck for use as backfill.

16.4.2Sill Development

There will be three sill development crews per shift. Each crew will consist of a lead miner and two development miners. The equipment used by the sill crews will include a 1-boom jumbo and 2 or 2.5yd LHD. The development crew will drill and blast, muck to a remuck, and install ground support from a leveled muckpile. The crew will remuck ore/waste into a 36 tonne (or 42 tonne) haul truck and a fourth worker (haul truck operator) will haul ore to surface and waste to another sublevel for use as backfill.

Typical sublevel development (835L) is shown in Figure 16.7.

Figure 16.7:835L Development (Plan)

Technical Report, Bell Creek Mine, 27 March 2015

114

16.4.3Primary Ground Support

Primary ground support will be installed in all underground excavations and will remain consistent with current practices. Standard primary ground support in development headings will include 1.8 metre resin rebar (1.2 metre x 1.2 metre pattern) with welded wiremesh screen installed in the back and shoulders to within 2.4 metres of the floor, and 1.2 Split Set bolts or 1.8 metre resin rebar bolts in the walls (also on a 1.2 metre x 1.2 metre pattern). Additional/alternate ground support measures may be required to accommodate local adverse ground conditions and may include shotcrete and/or cable bolts. The existing ground control quality control program will continue to be implemented.

16.5RESOURCE ANALYSIS (DILUTION AND RECOVERY)

16.5.1Mining Dilution

Two sources of dilution have been considered in establishing the Bell Creek Mine reserves.

Planned dilution includes low grade material and/or waste rock that will be mined and will not be segregated from the ore. Sources of planned dilution include:

·Waste rock or low grade material that is drilled and blasted within the drift profile of ore sills and the overall grade of the “muck” justifies delivery to the mill.

·Waste rock or low grade material within the confines of the stope limits. This includes internal waste pockets and footwall and/or hangingwall rock that has been drilled and blasted to maximize ore recovery and/or maintain favourable wall geometry for stability.

Wireframes have been designed for each stope in the mine plan. Planned dilution is directly reported from block model data within stope wireframes.

Unplanned dilution includes low grade resource, waste rock, and/or backfill from outside the planned drift profile or stope limits that overbreaks or sloughs and is mucked with the ore and delivered to the mill. Unplanned dilution has been calculated for each stope based on the local stope dimensions and geometry.

16.5.2Mining Recovery

Two recovery factors have been considered in establishing the reserves.

Planned recovery includes the in-situ block model resource that will be accessed, developed, and mined. Any measured and indicated resource not included in the mining shapes (i.e. stopes) has not been included in the reserves. Reasons that some block model in-situ resource will not be recovered include:

·A small volume that is separate from the main mining area and does not support the cost to develop and mine.

·The resource terminates between sublevels and would require mining excess dilution to recover.

·Random blocks within the block model that cannot be mined as part of an economic stope.

·Resource left in pillars (sill pillars and rib pillars) adjacent to previously mined stopes that have been backfilled with unconsolidated waste rock.

Technical Report, Bell Creek Mine, 27 March 2015

115

A mining recovery factor (unplanned recovery) has been applied to account for material that is planned to be mined within the confines of the stope wireframes, but will not be recovered due to factors such as:

·Poor ground.

·Blasting difficulties (ground does not break properly and cannot be recovered).

·Ore geometry.

·Broken ore that cannot be extracted (i.e. resting on the footwall, or around corners).

·Unplanned ore pillars left in place.

A 95% unplanned mining recovery has been considered in estimating the probable reserves mined to surface.

16.5.3Block Model In-Situ Cut-Off Grade

A 3.0 gram per tonne block model cut-off grade was used as an initial starting point to identify mining areas that require evaluation for potential mining. The assumptions made to establish the initial block model in-situ cut-off grade are summarized in Table 16.2:

Table 16.2:Assumptions for Initial Block Model In-Situ Cut-Off Grade

Item	Value
Mining (includes general and administration)	$75.0 /t
Sustaining Capital Cost	$20.0 /t
Milling	$22.0 /t
Total Cost	$117 /t ($CAD)
Mill Recovery	94.5%
Gold Price $US	US$1,100 /oz
Exchange Rate	0.90
Gold Price $CAD	CAD$1,225 /oz
Block Model In-situ COG	3.0 g/t

16.5.4Stope Shapes and Mining Plan

Based on the in-situ Indicated resource included in the Bell Creek block model, the following methodology was used to estimate the reserves.

1.The block model was reviewed in plan and in section to identify measured and indicated resource above the cut-off grade, and to confirm the applicability of the longitudinal longhole mining method. Some of the Indicated resource material remains in sill pillars left in previous mining areas, while the majority of indicated material lies in recently developed and currently undeveloped areas.

2.Sublevels were designed at 15 and 20 metre vertical intervals, and vertical sections were cut through the model along strike. On each vertical section, mining shapes were designed for each zone for each sublevel interval. The mining shapes were joined with adjacent sections to generate stope wireframes. A 2.4 metre minimum mining width was considered in the stope design. Note that there are some “blocks” that are in the block model, but are not included in stope wireframes. These are generally random blocks that are distant from planned mining areas and cannot be economically mined.

Technical Report, Bell Creek Mine, 27 March 2015

116

3.The in-situ tonnes and grade within each stope wireframe was extracted from the block model measured and indicated resource data. The in-situ tonnes and grade includes the planned dilution.

4.The unplanned dilution was estimated for each stope based on the stope size and geometry.

·The total stope volume was determined from the stope wireframe.

·The stope hangingwall and footwall area was calculated from the stope dimensions.

·The unplanned dilution from the hangingwall and footwall was estimated based on the dip of the stope using the criteria in Table 16.3.

·Backfill dilution from the floor (0.5 metres) and the adjacent stope endwall (0.3 to 0.4 metres) was estimated based on the floor and endwall dimensions.

Table 16.3:Hangingwall and Footwall Dilution Criteria

	Dip	Dip	Dip	Dip
Item	50-60°	60-70°	70-80°	80-90°
Hangingwall Dilution	0.45m	0.40m	0.30m	0.20m
Footwall Dilution	0.45m	0.40m	0.30m	0.20m

5.A 95% Mining Recovery factor was applied to the diluted resource for each stope.

6.The resulting diluted and recovered resource for each stope was reviewed. Diluted and recovered stopes above cut-off were included in the mine plan. Stopes below cut-off were re-designed to optimize the wireframe by reducing the stope size, or including a portion of the adjacent stope.

7.The sill development was removed from the stope resource and the development tonnes and grade distributed based on the development schedule.

8.A mine design was prepared for the identified resource, and schedule and costs applied to determine the overall economics.

16.5.5Estimated Reserve

From the mine plan, incremental, marginal, and overall mine economic cut-off grades were determined and used to finalize the estimated reserves. The incremental, marginal, and overall mine economic COGs are summarized in Table 16.4.

Technical Report, Bell Creek Mine, 27 March 2015

117

A development schedule, production profile, and mine design has been completed to estimate the capital and operating costs required to access, develop, and extract the Bell Creek Mine proven and probable reserves. When evaluating sublevels and stoping blocks, overall economics were considered including factoring in a risk free rate of return and profitability. A life-of-mine cash flow analysis has been completed to demonstrate that the proven and probable reserves support the operating costs and sustaining capital expenditures.

The diluted and recovered resource was estimated for each stope included in the mining plan. The estimated proven and probable reserves that have been included in the Bell Creek Mine plan are summarized by sublevel in Table 16.5.

1.The effective date of this report is December 31, 2014.

2.The mineral reserve estimates are classified in accordance with the Canadian Institute of Mining Metallurgy and Petroleum’s “CIM Standards on Mineral Resources and Reserves, Definition and Guidelines” as per Canadian Securities Administrator’s National Instrument 43-101 requirements.

3.Mineral reserves are based on a long-term gold price of US$1,100 per ounce and an exchange rate of 0.90 $US/$CAD.

4.Mineral reserves are supported by a mine plan that features variable stope thicknesses, depending on zone, and expected cost levels, depending on the mining methods utilized.

5.Mineral reserves incorporate a minimum cut-off grade of 2.7 grams per tonne. The cut-off grade includes estimated mining and site G&A costs of $77 per tonne, milling costs of $22 per tonne, mining recovery of 95.0%, external dilution of 13% and a metallurgical recovery rate of 94.5%.

6.The mineral reserves were prepared under the supervision of, and verified by, Natasha Vaz, P. Eng., Vice - President, Technical Services, Lake Shore Gold Corp., who is a qualified person under NI 43-101 and an employee of Lake Shore Gold.

16.6DEVELOPMENT SCHEDULE

Development and stoping activity schedules have been completed for the Bell Creek Mine using MS Project. Mining activities are resourced in the schedule and dumped into MS Excel spreadsheets for reporting.

16.7PRODUCTION PROFILE

The Bell Creek mine will operate two shifts per day, seven days per week. Underground crews and maintenance workers will work 10.5 hour shifts. Management, administration, and technical services staff will work eight-hour days from Monday to Friday, with appropriate coverage as required during weekends. Annual production has been based on operating 363 days per year.

Technical Report, Bell Creek Mine, 27 March 2015

119

Production will remain steady in Year 1 and Year 2 averaging approximately 770 tonnes per day while capital and operating development activities continue down to the 1165L. New mining blocks developed will contain more tonnes than previously mined blocks, providing an opportunity to bring multiple blocks in production simultaneously. In Year 3 through Year 5, development activities will reduce and development personnel and equipment will transition to support production activities. During these three years, production will increase and average approximately 1,000 tonnes per day.

All production activities have been scheduled in Microsoft Project.

16.7.1Production Summary

The life of mine production profile (based on the proven and probable reserves) is summarized in Table 16.6, and shown graphically in Figure 16.8 and Figure 16.9. Annual ounce production is presented as a range (upper and lower). The range is based on ±10% variance from the LOM plan to reflect potential differences in the combination of stopes that may be mined during each year.

16.9.1Fresh Air Supply

Based on the anticipated diesel equipment fleet, an estimated 213 cubic metres per second (cms) of fresh ventilation air will be required and 214 cms is planned to be delivered underground.

Fresh air will continue to be provided via the existing 4 metre diameter fresh air raise (FAR) from surface. To overcome increased ventilation pressures as mining progresses deeper, a second fan (447kW- 84”-600hp) has been installed on the surface FAR. Air is currently transferred via internal fresh air raises to the 760L. A 4.0 metre diameter raisebored raise will connect the FAR from 670L to 805L and is scheduled to be completed by the end of May 2015. The internal fresh air raise system will be extended in increments (4 m x 30 m drop raises) as the ramp development progresses from 805L to 1165L. At each ventilation raise access, a ventilation wall will be constructed and auxiliary fans will direct air to the workplace from the ramp through flexible ventilation ducting.

16.9.2Exhaust Air Return

Used ventilation air will continue to exhaust from the mine via the ramp, shaft, and 240L-Surface return air raise (RAR). There will be no exhaust fans utilized.

16.9.3Secondary Egress

The main ramp from surface will be the primary access to and from the mine.

The secondary egress from surface to 240L station will be via the existing manway in the shaft. Below 240L station, the main ramp and internal raises equipped with ladder ways will provide a second access route.

16.9.4Mine Air Heating and Cooling

The existing surface ventilation heating plant consists of two ACI-Canefco Inc., MAH 250 mine air heaters (22 MBTU). These heaters will continue to be used for the life-of-mine. The mine design extends to 1,165 metres below surface. Mine air cooling requirements are not anticipated for mining at this depth.

A simplified long section view schematic of the ventilation and escape way system is shown in Figure 16.10.

16.11UNDERGROUND MINE SERVICES

The underground mine services include electrical power distribution and communications, compressed air, service water, and dewatering.

16.11.1Electrical Distribution and Communication

The main trunk of the electrical and communications distribution systems are already in place and will expand as the mine develops into new production areas.

Power will continue to be delivered underground via electrical cables installed in the existing ramp, ventilation raise, escape-ways, and in the shaft. The underground power distribution system includes:

·A 2MVa, 27.6kV/4,160V transformer/substation located near the portal distributes 4,160V via the ramp to 370L then through boreholes to 655L Feeds substations at 60L. (750kVa), 120L (750kva), 300L (750kva), 330L (750kva), 365L (750kva), 460L (750kva), 520L (1,000kva), 550l (1000kva), 580ml (1000kva), 610L (1000kva) and the 655L (1000kva).

·A 5MVa, 27.6kV/13.8kV transformer/substation located near the headframe distributes 13.8kV through the ventilation raise to a 120L 2MVa, 13.8kV/4,160V transformer/substation at the 120L. The 120L substation distributes power through a series of boreholes and escape-ways to feed the substation at 685L (1000kva), 700L (1000kva), 730L (1000kva), 760L (1000kva) and 790L (1000kva).

·A 3,750kva Transformer located near the hoist-room distributes power down the shaft to 60L, 120L, and 240L. This supplies the power for the main pumping station at 240L (750kva).

As the mine expands to 1165L, electrical substations (mine load centres) will be located in electrical cut-outs on sublevels.

The existing “leaky feeder” communications system main trunk line is located in the main ramp and will be expanded to the new working ramps.

Technical Report, Bell Creek Mine, 27 March 2015

126

A fibre optic cable is used for gas monitoring, phone and network communications and runs from surface, down the ventilation raise, to the 120L electrical cut-out. From the 120L fibre optic is distributed through the main ramp and a series of boreholes and raises to operating sublevels in the mine.

16.11.2Compressed Air

The site currently has two 1,600 cfm, 300hp Sullair air compressors and two rental 700 cfm, 150hp compressors located 730L and 745L, supplying the underground pneumatic powered equipment. A new 1600 cfm 300hp LS25S -300L Sullair Rotary Screw air compressor will replace the two rental units in 2015.

Compressed air is delivered underground via piping in the ramp (152mm diameter) and via the shaft (152mm diameter). The underground compressed air distribution system consists of steel piping installed in the ramps and sublevels. Underground compressed air usage includes:

·Jackleg and stoper use for ground support installation and construction.

·Pneumatic Anfo loaders.

·Blasthole/bootleg cleaning for development rounds.

·Pneumatic longhole drills.

·Longhole cleaning.

·Refuge station ventilation (pressurizing).

·Pneumatic cylinders for door controls.

·Pneumatic pumps for local dewatering.

16.11.3Service Water

All service water required for underground drilling operations, dust suppression, and washing work places is supplied from a sump at 60L that collects clean, natural water inflow from the surrounding rock mass. Water from the collection sump is pumped into a containment tank. A submersible pump in the tank feeds a 102mm diameter steel pipe in the ramp system that gravity feeds all sublevels in the mine.

16.11.4Mine Dewatering

Water inflow from the rock mass and service water used for drilling activities and dust suppression is currently collected in local sumps and directed to main sumps/pump stations at the 120L and 240L through a network of drain holes, pumps (19hp Flygt and 30hp Tsurumi), and dewatering lines in the ramp (including a shaft bottom pump). The 120L pump station includes 2 x 140hp Flygt pumps and the 240L pump station includes 2 x 250hp Technojet MH125-150a multistage pumps. Both pump stations feed a 152 mm diameter steel pipe in the shaft. At surface, the mine water is directed to the polishing pond and/or mill clear water pond.

As the mine expands into new production areas, additional sumps and pumps will be constructed and will feed into the existing dewatering system. The pump stations will transfer water to the main sump at 240L.

Technical Report, Bell Creek Mine, 27 March 2015

127

16.11.5Roadbed Material

The maintenance of roadways will be essential in reducing the mobile equipment operating and maintenance costs and achieving high haulage truck availability.

Crushed/screened rock will be prepared for use underground and will be delivered underground and distributed via production equipment and spread using the existing grader.

16.12MATERIALS SUPPLY

The Bell Creek Mine is well positioned in the established Timmins mining district. Consumable materials and external services required to support the mining operation will continue to be sourced from local businesses or from other nearby mining centres (such as Sudbury, Kirkland Lake, North Bay, and Rouyn-Noranda). A number of contracts have been established to support current site activities and these will be amended as required to meet production demands.

16.13MAINTENANCE

There are existing maintenance facilities on surface to support maintenance of surface equipment and equipment brought to surface from underground. Mobile equipment will be brought to the shop for servicing, preventive maintenance, and repairs. A mechanic will be available (each shift) to service certain mobile equipment (such as longhole drills and jumbos) underground and tend to minor breakdowns in the field.

16.14SAFETY

The site has existing health and safety programs in place as required by the Ontario Occupational Health and Safety Act and Regulations for Mines and Mining Plants. There is an existing Joint Health and Safety Committee and Mine Rescue Team and training facilities.

There is currently a full time Safety Coordinator on site (shared with the mill) and this position will remain filled for life of mine operations. The Safety Coordinator will maintain site safety programs and initiatives. There will be a trainer on staff.

16.15GEOMECHANICAL

LSG contracts Mine Design Engineering (MDEng) for geomechanical engineering support for the Bell Creek Mine. In May 2013, MDEng completed a review of the minimum ground support standards, sill pillar stability, and stope dilution potential. The review included a geotechnical data collection program of the 550, 565, 580, 595, 610, and 625 Levels. The executive summary from the review report follows.

Mine Design Engineering has been retained by LSG to complete a review of the Bell Creek ground support standards, provide recommendations for the thickness of pillars to be left under uncemented rock fill, and complete an ELOS (Equivalent Linear Overbreak or Sloughage) assessment of dilution potential. In addition to these analyses items a geotechnical data collection program has also been completed involving geotechnical mapping of the 550, 565, 580, 595, 610 and 625 Levels.

Technical Report, Bell Creek Mine, 27 March 2015

128

More than 1,000 structural measurements were made during the April 2013 geotechnical data collection campaign. From this data, the rock mass conditions have been characterized for Bell Creek Mine (550 to 625 Levels).

·The structural fabric is dominated by well-developed foliation parallel jointing. Foliation jointing is bi-polar in nature (Set A/A’). Foliation jointing is typically smooth and planar. Joint surfaces are either clean or coated with mineral infilling. Foliation parallel jointing is typically closely spaced (10cm) and spacing typically decreases in proximity to foliation parallel shears.

·A well-developed sub-horizontal joint set (B) is characterized by smooth to rough and planar or stepped joints with thick calcite infilling and joint spacing in the order of 0.5 to 1 metre.

·A weakly defined joint set (C) does occur; however, this set is not consistently observed in all mapping areas. Set C (typically clean, smooth to rough and planar) may be considered a random feature.

·Random jointing is considered rare at Bell Creek.

·Slips and shears commonly feature breccia and gouge with calcite, chlorite and graphitic mineral infilling and are typically parallel to the east-west striking sub-vertical structural fabric.

·The rock mass is highly anisotropic.

·By RMR classification the Bell Creek rock mass ranges from fair to very good quality, and is typically good. By the Q classification system the Bell Creek rock mass ranges from very poor to very good, and is typically fair.

·Rock mass quality was observed to be locally reduced near shears (particularly near shear zones with heavy graphitic mineral infilling).

A review of the Bell Creek ground support standards has been completed. It has been concluded that:

·The bolting patterns specified for varying spans are adequate for back support at Bell Creek.

·Support design should be locally assessed where adverse ground conditions are encountered (i.e. where shears or faults occur) or for spans exceeding 9 metres in temporary openings and 11 metres in permanent openings.

·The current sidewall support standard for 1.5 metre split sets is adequate for 3 metre drift heights. It is recommended that the support standard for sidewalls in drifts 3 to 5 metres in height be changed to 1.8 metre rebar on a 1.2 metre x 1.2 metre pattern. For drifts 6 metres in height 2.4 metre rebar should be utilized on the same 1.2 metre x 1.2 metre pattern. If sidewall height exceeds 6 metres in height site-specific support should be designed by a qualified engineer.

·Screen should be brought to within 1.5 metres of the floor and be installed with 3 squares of overlap. Note: This recommendation has since been revised to within 2.4 metres of the floor.

·It is recommended that wide spans be instrumented with multi-point borehole extensometers (MPBXs) in order to measure ground deformations (and subsequently estimate support loads).

Empirical assessment of HW dilution potential suggests that 0.75 to 1.25 metres of equivalent linear overbreak/sloughage can be expected from stope hangingwalls (at roughly 600 metre depth). It may be possible to minimize hangingwall instability with cablebolts installed perpendicular to foliation jointing from hangingwall development drives and avoidance of undercutting the hangingwalls with the lower sill development drives.

Technical Report, Bell Creek Mine, 27 March 2015

129

Numerical models have been used to assess sill pillar thickness requirements, it has been recommended that:

·Sill pillars over stopes with hangingwall to footwall spans less than 4 m wide be designed with a width to height ratio of 2 (2 metre wide stope = 4 metre sill pillar).

·Sill pillars over stopes with hangingwall to footwall spans equal to or greater than 4 metres wide be designed with a width to height ratio of 1.5 (4 metre wide stope = 6 metre sill pillar).

·Sill pillar width to height ratios should be re-evaluated as mining continues to depths below 650 metres. Evaluations of sill pillar performance should be utilized to verify the assumptions made for numerical modeling (i.e. in-situ stress magnitudes, and UCS).

As mining progresses to depth and the extraction ratio increases it may be advisable to introduce a microseismic monitoring system. A cost/benefit assessment of a microseismic system will be largely influenced by long-term mine plans.

The following geomechanical action items are recommended for Bell Creek:

·It is recommended that stress modeling be completed to mitigate risks to production and safety associated with elevated magnitudes of mine induced in-situ stress conditions. Numerical modeling can also be used to assess the siting of permanent underground infrastructure (i.e. ramps, shops, refuge stations) so as to minimize the risk of these excavations being exposed to high mine induced stress magnitudes.

·It is recommended that semi-annual reviews by a rock mechanics expert be scheduled. These reviews should typically take 4 or 5 days and involve underground inspections to assess changes to ground conditions and support system quality as well as reviews all geomechanical aspects of mine plans.

In February 2015, MDEng completed a site visit to inspect ground support conditions and provide a high-level geomechanical review of the mine plans. Observations and recommendations from the site visit have been documented in a technical memo issued by MDEng on February 28, 2015 titled “Summary of February 2015 Site Visit”. The site visit included:

·Observation of cable bolting practices and recommendations for quality control improvements.

·Observation of primary ground support practices and recommendations for quality control improvements.

·Observation of ground support material storage practices.

·Observation of general ground conditions and areas where ground support rehabilitation is recommended.

·Recommendations for further geotechnical data collection programs on new sublevels.

The site visits and reviews by rock mechanics experts are planned to continue at Bell Creek Mine.

17.0RECOVERY METHODS

Ore from the Bell Creek Mine is milled exclusively at the Bell Creek Mill located approximately 6.7 kilometres north of Highway 101 in South Porcupine, Ontario. The current 3,300 tonne per day processing plant consists of a one stage crushing circuit, ore storage dome, one-stage grinding circuit with gravity recovery, followed by pre-oxidation and cyanidation of the slurry with CIL and CIP recovery. Ore from the Timmins West Mine is also trucked to the Bell Creek Milling facility for processing.

17.1HISTORY

The Bell Creek Mill was established as a conventional gold processing plant utilizing cyanidation with gravity and CIP recovery. Between 1987 and 1994 the mill processed 576,017 short tonnes of Bell Creek ore grading 0.196 ounce per short tonne Au (112,739 recovered ounces). The historical gold recovery was approximately 93 percent. Additional tonnage from the Marlhill Mine, Owl Creek open pit, and Hoyle Pond Mine was processed prior to the mill being placed on care and maintenance in 2002. During this period several improvements and additions were implemented to increase tonnage throughput from the original 350 tonnes per day to 1,500 tonnes per day. Lake Shore Gold (LSG) purchased the mill in 2008 and re-commissioned the mill for operation in 2009 at 1,000 tonnes per day. The mill was expanded to 2,000 tonnes per day in the fourth quarter of 2010 and was further expanded to 2,500 tonnes per day in 2011. Phase 2 of the mill expansion (increasing throughput capacity to 3,300 tonnes per day) was completed in the third quarter of 2013.

17.2BELL CREEK MILL PROCESS DESCRIPTION

Ore from the Bell Creek Mine is dumped directly onto a 16” by 16” grizzly at the truck dump and a remote controlled rockbreaker is used to break up the oversized material. The ore is fed with an apron feeder to a series of conveyors reporting to a scalping grizley feeder in the crushing building. The openings between the fingers on the grizley feeder are 3.5”, with the oversize reporting to a 44” x 34” C110HD Metso jaw crusher. The jaw crusher is set to a closed side setting of 4”. The discharge from the crusher is combined with the -3.5” material from the grizley feeder and conveyed to the ore storage dome. The dome has a 20,000MT storage capacity, 6,000MT of which is live. Three apron feeders pull ore from the dome and convey it to the SAG mill building.

The grinding circuit consists of one 22’ diameter by 36.5’ length low aspect ratio Metso SAG mill and is powered by twin 6,250 hp (4,600 kW) motors. The SAG mill is a repurposed ball mill converted to a SAG by installing ½” grates and a trommel with ¾” openings. Oversize from the trommel reports to a collection bin which is fed back into the SAG mill feed chute. Undersize from the trommel reports to a pumpbox which feeds a cyclopac equipped with 6 outlets. Four of the outlets are fitted with 20” Krebs gMAX cyclones, and the other two outlets are capped and available for possible future expansion. The SAG cyclone overflow reports to the thickener feed box and the underflow reports back to the SAG mill. A portion of the cyclone underflow is fed to a 30” Knelson. Knelson concentrate is collected in a hopper and is pumped daily to the refinery for further treatment, while the Knelson tails flow by gravity back to the SAG mill. Target grind is 80% passing 200 mesh.

Flocculent is added to the cyclone overflow and is pumped to a 20 meter diameter thickener. The slurry from the cyclones is 25-35% solids by weight with the thickener underflow at 55% solids by weight. The thickener overflow water is pumped to the process water tank and reused in the grinding process. The thickener underflow slurry is pumped to the leach circuit. The leach circuit consists of five agitated

Technical Report, Bell Creek Mine, 27 March 2015

131

tanks in series with a total volume of 1,940 cubic meters. Pure oxygen is sparged into the first three leach tanks to passivate the contained pyrrhotite in the ore, as well to maintain a target dissolved oxygen level, which is required for efficient gold dissolution in cyanide. Cyanide is then added to leach tank #4, or #5.

There are three carbon-in-leach (CIL) tanks equipped with Kemix screens having a total volume of 7,500 cubic meters. The first tank (CIL #5) operates without carbon, so it is essentially a leach tank. The second (CIL #2) and third (CIL #1) tanks contain roughly 8 grams of carbon per liter of slurry. The circuit will reach equilibrium for loading of the carbon with the grade of the loaded carbon in the range of 2,500 to 4,500 grams per tonne. Loaded carbon is pumped from CIL #2, screened, washed, and then transferred to the loaded carbon tank. Carbon in the CIP and CIL tanks is advanced counter-current to the flow of slurry in the circuits.

The slurry from CIL #1 tank reports to the carbon-in-pulp (CIP) circuit, and is split into two trains of three CIP tanks in parallel with approximately 45 grams of carbon per liter of slurry. Recovery of the gold from the carbon is a batch process with carbon being stripped at a rate of 3.5 tonnes per batch. The turnaround time between batches is 24 hours. Carbon can be cleaned with acid, reactivated with the kiln and reused in the circuit.

The loaded solution from the strip circuit is passed through two electro-winning cells in the refinery. The gold collects on the cathodes in a sludge form. The cells are washed weekly and the sludge is collected in filter bags and dried. The dried sludge is then mixed with reagents and melted in the induction furnace. Gold bullion bars are poured when the melt is completed.

The gravity gold material collected from the Knelson concentrator is transferred to the refinery and a gravity table is used to increase the gold content. The concentrate is then dried, reagents are added and the material is melted in the induction furnace. The gravity concentrate and the CIP gold sludge are melted separately due to the differing amounts of reagents used in each, and to more accurately determine recoveries in each circuit.

17.3METALLURGICAL BALANCE

A metallurgical balance is conducted daily based on the tonnage from the 4 roller belt weightometer located on the feed conveyor to the SAG mill. The total tonnage, corrected for moisture, and assays from the daily sample campaign are used to produce the balance. All samples are assayed in accordance with typical assay standards and a QA/QC program is in place to ensure the integrity of the assay lab processes. The main components used to calculate the daily balance are the thickener underflow solids and solution, the weight of gravity gold collected, the estimated grade and moisture content of the gravity gold collected, and the tailings sample solids and solution. The daily metallurgical balance is a best estimate of daily production which must then be reconciled with the circuit inventory and bullion poured (this reconciliation is performed on a monthly basis). All areas of the circuit are sampled for tank level, percent solids, solids grade, solutions grade, carbon concentrations and grade (where applicable). As the carbon contains the majority of the gold in inventory, strict care is taken to ensure sampling is performed correctly.

The final clean out of the electro-winning cell is completed by the refiner or his designate, under security control. All sludge is collected and dried. The washed cathodes from the cells are weighed and the weights are recorded to determine whether any plating buildup is occurring. The dried cell sludge and

132

the gravity concentrate collected over the same period are smelted and bullion bars are poured. The bars are stamped and their weights are recorded and verified. Bullion samples are taken and are assayed at the Bell Creek Lab. These sample results are used in the metallurgical balance.

20.0ENVIRONMENTAL STUDIES, PERMITTING AND SOCIAL OR COMMUNITY IMPACT

20.1REGULATORY AND FRAMEWORK

This section provides an overview of the environment related authorizations that are required for the operation of Bell Creek Complex (i.e. the Bell Creek Mine and Bell Creek Mill). Legislation related to routine operational monitoring, reporting, and notifications is not discussed herein.

20.1.1Provincial Environmental Assessments

Mining projects, normally being private projects, are generally not subject to the Environmental Assessment Act unless designated. If a project becomes designated, then the project must complete an Individual Environmental Assessment (EA) prior to any permits being issued.

The provincial environmental assessment process is often triggered by specific components of a project rather than the entire project itself.

A Class EA process may apply to the project as a result of approvals under the Ministry of Natural Resources and Forestry (MNRF). Typically, Class EAs are required for work on roads and dykes, roads and water crossings, stream bank rehabilitation work, and related construction including dredging and filling activities. The Class EA must be completed prior to the issuance of the Land Use Permit or Work Permit under the Public Lands Act and the Lakes and Rivers Improvement Act, respectively.

Class EAs may also be triggered for approvals issued by the Ministry of Transportation (MTO) as a result of construction or re-alignment of a provincial highway during the development of a mining project. Some transmission lines and transformer station projects are also subject to review under the Class EA for minor transmission facilities.

20.1.2Federal Permits

The Canadian Environmental Assessment Act (CEAA) applies to mining projects for which the federal government exercises authority on some aspect of the Project. For mining projects, the CEAA process is usually triggered when activities listed in “Regulations Designated Physical Activities” are matched and/or exceeded. Once this is determined the project is measured with Item 5 of the regulation (CEAA 2012).

Once the possibility exists of an activity potentially requiring an authority, a Project Description must be submitted to the agency, the Federal permitting process is timed for 365 days not including any additional requests required by the agency.

20.1.3Provincial Permits

Ministry of Northern Development and Mines

Provincially, the Ministry of Northern Development and Mines (MNDM) is the lead agency for mining projects in Ontario. Mine production triggers requirements under Part VII of the Mining Act. These requirements include notifications, public and First Nations consultation, closure plans and financial assurance. Approval of a closure plan provides rights for the company to proceed under the Mining Act.

Technical Report, Bell Creek Mine, 27 March 2015

137

Mine production is not allowed on unpatented mining claims and public notice is mandatory for mine production.

Ministry of the Environment and Climate Change

The Ministry of the Environment and Climate Change (MOECC) issues permits to take water (both surface and groundwater), emit noise and dust, and discharge into water, land and the atmosphere. The MOECC will administer the following permits for the Bell Creek Complex:

·Wastewater treatment and effluent discharge from the mine process water, including construct and operate tailings impoundment — Ontario Water Resources Act (OWRA).

·Water taking permits — OWRA.

·Industrial Sewage Works Permit — OWRA.

·Solid waste management (waste generator registration) — Ontario Environmental Protection Act (EPA).

·Noise/air emissions — EPA.

Currently, the Bell Creek Complex operates under the following permits issued by the MOECC:

·Permit to Take Water # 6153-84WPMB issued April 28, 2010

·Amended Environmental Compliance Approval (Industrial Sewage) No. 9641-9SSJTH issued January 16, 2015

·Amended Environmental Compliance Approval (Air) No. 0303-9G8RUY issued March 21, 2014

·Waste Generator No. ON7562685.

Ministry of Natural Resources and Forestry

The MNRF issues land use permits and work permits under the Public Lands Act and the Lakes and Rivers Improvement Act, respectively. The MNRF will administer the following permits for the Bell Creek Complex:

·Forest Resource Licenses which are issued for the cutting of crown owned timber (Crown Forest Sustainability Act

·Land use permits for such things as effluent ditches/pipelines, access roads, camps, etc., where the acquisition of crown lands is required — Public Lands Act (PLA).

·Work permits for such things as creek crossings or impoundment structures (dams) - Lakes and Rivers Improvement Act (LRIA).

20.2ENVIRONMENTAL IMPACTS

Water management and protection of the natural environment surrounding the Bell Creek Complex were recognized from the onset of the project as primary environmental concerns.

All construction and works conducted at Bell Creek passes through extensive screening by both Lake Shore Gold (LSG) staff and a third party consultant to minimize impact to Bell Creek and best manage water and air releases as per LSG’s operating permits. Detailed engineering reports assist staff in managing the above mentioned concerns from the site.

Technical Report, Bell Creek Mine, 27 March 2015

138

The development of the mine will create a disturbance footprint on the terrestrial environment. Baseline work did not identify the possibility of provincially or federally listed fauna species on the site that will trigger concern. The Closure Plan will reduce this disturbance area at closure and disturbed areas will be rehabilitated with the intent of returning the site to a productive use (i.e. forestry) resulting in limited long-term impact to the area. An overview of the Bell Creek Complex water management plan has been summarized in Figure 20.1.

Figure 20.1:Bell Creek Complex Water Management Plan

20.3ENVIRONMENTAL MONITORING PROGRAM

Environmental monitoring will be conducted in accordance with regulatory requirements. The monitoring program will be compiled in a database to assure compliance with all regulations. General components of the environmental monitoring program are described in the bullets below.

·Thrice weekly sampling during discharge to the Porcupine River as per the Municipal Industrial Strategy for Abatement (MISA), Environmental Compliance Approval (ECA) # 9641-9SSJTH and the Metal Minning Effluent Regulations (MMER).

Bulk containers of petroleum products are stored in designated areas within Maintenance area. Spill trays are utilized for containment.

Fuel will be stored and handled in accordance with the Liquid Fuels Handling Code. Gasoline and diesel fuel will be stored in the tank farm and in portable, double-hulled tanks that are located within containment areas to contain incidental spillage. Propane is stored in above ground tanks.

There are no PCBs at the Bell Creek Complex.

With the exception of silica dust from development rock, there will be no designated substances at the Bell Creek Complex, as defined in the Occupational Health and Safety Act.

Explosives will be brought to the Bell Creek Complex on an as-needed basis. All explosives are stored in powder magazines in the underground workings of the Bell Creek Mine.

20.5SPILL AND EMERGENCY RESPONSE PLAN

As part of the Safety and Environment Program, LSG has prepared a Spill Prevention Contingency and Response Plan (SPCR) for the Bell Creek Complex. This document provides a practical guide for preventing, controlling and responding to spills. It has been prepared using guidelines provided by the Liquid Fuels Handling Code, the Canadian Environmental Protection Act, the Ontario Environmental Protection Act, the North American Emergency Response Guidebook, as well as standardized response procedures from petroleum product suppliers. Copies of this document are available at Security, Health and Safety Department and also the Environmental Department.

20.6CLOSURE PLANNING

Mine closure is the orderly, safe and environmental conversion of an operating mine to a “closed-out” state.

The development of a walk-away, no active management scenario is a primary environmental management goal for this project. The long-term environmental management issues associated with the project have been identified in the Mining Act and relate to ore hoisted to surface, waste rock dumps, open holes to surface and overall construction of permanent structures. Other secondary issues, such as returning the site to a productive use (i.e. forestry) will be accommodated within the context of the Closure Plan.

Currently, with the extensive sampling program initiated by the Bell Creek Complex, the analytical data collected does not identify any potential acid rock drainage issues.

At the conclusion of the mine life, the closeout rehabilitation measures summarized below will be implemented.

·Removal of surface buildings and associated infrastructure.

·Removal of holding ponds by converting into naturally draining ponds

·Sloping and covering any and all waste rock/tailings with native grasses

·Securing mine opening as per O. Reg 240/00

·Ensuring water quality as per monitoring program submitted in Closure Plan

20.7CONSULTATION

Consultation is being undertaken with regulatory agencies, the general public, the Métis Nation of Ontario, Wabun Tribal Council and the First Nation communities of Flying Post First Nation, Mattagami First Nation, and Matachewan First Nation, who are represented by Wabun Tribal Council, and also Wagoshig First Nation. Consultation provides an opportunity to identify and address the impacts of LSG’s activities on external stakeholders and to expedite the authorization process.

The consultations have been held in order to comply with LSG corporate policy, the provincial requirements of Ontario Regulation 240/00 and the Environmental Bill of Rights.

An Impact and Benefits Agreement (“IBA”) is currently being negotiated. The IBA will outline how LSG and the First Nations communities will work together in the following areas: education/training of First Nation community members, employment, business and contracting opportunities, financial considerations and environmental provisions.

23.0ADJACENT PROPERTIES

23.1GENERAL STATEMENT ABOUT ADJACENT PROPERTIES

The Bell Creek Mine is situated on the New Mines Trend, 2.8 km west of the centre of Goldcorp’s past producing Owl Creek Pit, and 5 km west of Goldcorp’s operating Hoyle Pond Mine. The term New Mines Trend was coined by PFV and Kinross to promote and describe the area of the Hoyle antiform and synform which hosts significant past production and unexploited Mineral Resources and Reserves.

23.2OWL CREEK PIT

The Owl Creek Mine is located near the west end of the Neo-archean Abitibi greenstone belt, 17 km northeast of Timmins, Ontario, and 4 km north of the Destor Porcupine fault. Gold occurs in epigenetic quartz veins and their pyritic wall rocks in two zones within a package of east striking, steeply north dipping, volcanic and sedimentary rocks. At the West Zone, 1,729,603 tonnes of ore with a grade of 4.83 g/t Au (268,587 troy oz.) were produced from an open pit centered on a wedge-shaped unit of Tisdale Group basalt that occurs between two overturned, south facing units of Porcupine Group greywacke and argillite. Basalt/greywacke contacts are locally marked by graphitic-carbonaceous argillite, strike-parallel faults and massive quartz veins. Deformed quartz +/- ankerite veins occur along the graphitic sedimentary/volcanic contacts and in gently to moderately dipping fractures in basalts, and, to a lesser extent, in greywackes. Veins also occur sub-parallel to steeply dipping 070 degrees foliation. Altered host basalts are composed of iron carbonate, sericite, quartz, carbon, chlorite and disseminated pyrite. Gold occurs as inclusions in pyrite, and less commonly as free gold in fractures and along graphite-quartz grain boundaries in quartz veins (Coad, 1998.).

The Authors have been unable to verify the information presented above, and notes that this information is not necessarily indicative of the mineralization on the property that is the subject of the technical report.

23.3HOYLE POND MINE

The Hoyle Pond and 1060 zones occur within a south-facing sequence of komatiitic and tholeiitic volcanic rocks both underlain and overlain by greywackes. The metavolcanic-metasediment sequence has been regionally drag-folded into a Z-shaped, E-plunging anticlinal form in the mine. A stacked series of gold-bearing veins follow the E-plunging antiform with both steeply dipping limb vein systems and flat vein systems across the axis of the fold. Mineralization usually comprises coarse free gold in white to grey quartz veins within a carbonate-sericite alteration envelope along with pyrite, arsenopyrite, and tourmaline. The 1060 zone is described as a steeply dipping vein set on the south limb of the antiform. Mineralization is generally similar to the vein systems adjacent, but fuchsite and sphalerite have also been noted in the 1060 zone. Gold-bearing veins range in width from 0.2 to 7 metres with a minimum mining width set at 1.5 metres, Butler (2008).

Hoyle Pond has produced in excess of 3.2M ounces of gold since production started in 1985.

25.0INTERPRETATION AND CONCLUSIONS

25.1MINERAL RESOURCE ESTIMATE

The Mineral Resource estimates for the Bell Creek Mine are based on 119 historic diamond drill holes and 819 diamond drill holes completed by Lake Shore Gold (LSG) (938 total diamond drill holes).

The resource totals 4.90 Mt at 4.36 g/t Au (686,800 ounces of gold) in the Measured and Indicated categories and 4.40 Mt at 4.84 g/t Au (685,000 ounces of gold) in the Inferred category. Resources occur within sixteen mineralized domains, with the North A, North A2, North B and North B2, accounting for 91% of the contained ounces.

The resources were estimated using the Inverse Distance Squared (ID2) interpolation method with gold assays capped to 44 g/t for the North A Zone, and 34 g/t for all other zones excepting the Hangingwall veins which were capped to 25 g/t. Resources are reported above a 2.2 g/t cut-off with no allowance for dilution.

Diamond drilling and underground development has demonstrated continuity of grade, mineralization, and geologic structure to support the definition of a reasonable prospect of economic extraction defined by CIMM standards for indicated and inferred resource classifications. The estimated Resources at Bell Creek Mine are summarized in Table 25.1.

Table 25.1:Bell Creek Mine Resource Estimates

Category	Tonnes	Capped Grad (g/t Au)	Capped Ounces Au
Measured	331,000	5.25	55,900
Indicated	4,573,000	4.29	630,800
Measured and Indicated	4,904,000	4.36	686,700
Inferred	4,399,000	4.84	685,000

Notes

1.The effective date of this report is December 31, 2014.

2.The mineral resource estimates have been classified according to CIM Definitions and Guidelines.

3.Mineral resources are reported inclusive of reserves.

4.Mineral resources incorporate a minimum cut-off grade of 2.2 grams per tonne for the Bell Creek Mine which includes dilution to maintain zone continuity.

5.Cut-off grade is determined using a weighted average gold price of US$1,100 per ounce and an exchange rate of 0.90 $US/$CAD.

6.Cut-off grade assumes mining and G&A costs of up to $77 per tonne and/or processing costs of $22 per tonne and assumed metallurgical recovery of 94.5%.

7.Mineral resources have been estimated using the Inverse Distance Squared estimation method and gold grades which have been capped between 25 and 44 grams per tonne based on statistical analysis of data in each zone.

8.Assumed minimum mining width is two metres.

9.The mineral resources were prepared under the supervision of, and verified by, Eric Kallio, P. Geo., Senior Vice-President, Exploration, Lake Shore Gold Corp., who is a qualified person under NI 43-101 and an employee of LSG.

10.Tonnes information is rounded to the nearest thousand and gold ounces to the nearest one hundred, as a result totals may not add exactly due to rounding.

Technical Report, Bell Creek Mine, 27 March 2015

A sensitivity analysis was carried out to examine the impact on the tonnage, average grade and contained ounces by varying the cut-off grade. The results are presented graphically in Figure 25.1. By increasing the cut-off grade, the model demonstrates opportunity to optimize resources.

Figure 25.1:Grade-Tonnage Graph (as function of cut-off grade)

Validation of the block model was performed visually through a comparison of drill intercepts and block model results on plans and section. Sill development demonstrates reasonable correlation with the 3D shapes and grade trends predicted by the Bell Creek block model. Diluted stope production reported from the Bell Creek block model demonstrates reasonable correlation with the mill reconciled production in terms of tonnage, grade, and ounce content.

Information on metallurgical behavior and recovery is available from historic milling data (above the 300 metre Level including laboratory test work) and from recent Lakeshore Gold production between the 300 and 730 metre Level. Visual evidence in diamond drill core does not exist to suggest that metallurgical recovery would vary at depth however this cannot be confirmed with information currently available.

25.2MINERAL RESERVE ESTIMATE

The subset of the total Bell Creek Mine resource pool considered in this report includes the measured and indicated resource material located between the 445L and 1165L. A mine design was completed on this material to estimate the proven and probable reserves. The mine design used for the updated reserves estimate has been based on existing surface and underground infrastructure and operating

Technical Report, Bell Creek Mine, 27 March 2015

151

experience. The majority of the main mine infrastructure (surface and underground) is in place, most equipment has been purchased, and the Bell Creek Mill is capable of meeting production requirements. Bell Creek Mine successfully uses the narrow longitudinal longhole mining method which is commonly used for deposits with similar geometry and conditions. The operation also uses common, proven mining equipment and has experienced management and mine operations personnel. The Timmins area has a significant, well-established mining service/supply industry to support the operation. Through operating experience, the operation has implemented the systems and programs (i.e. health and safety, environment, training, maintenance, operating procedures, etc.) necessary to sustain production. This experience has also provided a solid basis for estimating the capital and operating costs used in preparation of the LOM plan.

Mining shapes (stope wireframes) were designed in three dimensions for all measured and indicated resources included in the mining plan and the in-situ resource within the stope wireframes (including any low grade or barren material) was extracted from block model data. External dilution was estimated for each stope based on stope geometry and a 95% mining recovery factor was applied to account for unplanned losses. Stope cut-off grades were estimated to determine which stopes to include in the reserves. Detailed mine development layouts and construction activities were assigned to provide access to each of the stoping units. A detailed LOM development and production schedule was prepared to estimate the annual tonnes, average grade, and ounces mined to surface. Development, construction, and production costs were estimated to allow an economic assessment to be made comparing the capital and operating expenses required for each area to the expected revenue stream to ensure economic viability.

Key outcomes of the LOM plan include an updated reserves estimate of approximately 1.8 million tonnes grading 4.6 g/t (approximately 263,600 ounces). The reserves support a mining plan at a production rate of approximately 770 tonnes per day in Year 1 and Year 2 and increasing to approximately 1,000 tonnes per day in Year 3 through Year 5, before ramping down and ending in Year 6. The reserves can be extracted at an estimated average operating cost of $100.3 per tonne with estimated sustaining capital costs of approximately $62.6 million.

25.3RISKS

The realized grade in any mining plan has one of the greatest impacts on financial returns. Ongoing diamond drilling and close attention to sill development mapping and efforts to minimize dilution must be continued to reduce this risk going forward.

Gold prices are subject to significant fluctuation and are affected by a number of factors which are beyond the control of LSG. Lower than predicted gold prices will reduce the projected cash flow.

Currency fluctuations are also affected by factors which are beyond the control of LSG. A stronger than predicted Canadian dollar versus the U.S. dollar will reduce the projected cash flow.

Operating and capital costs have been based primarily on actual performance metrics of the operation since 2012. These factors are considered low risk elements and have intrinsically less impact on financial returns.

Social, political, and environmental factors are all considered to be low risk factors for the Bell Creek Mine.

26.0RECOMMENDATIONS

26.1DRILLING

26.1.1Deposit Program

In order to maintain production levels, a continuous level of overlapping short and longer term definition drilling programs are required. The current 2015 budget includes 18,415 metres of drilling that will address near and mid-term production decisions.

To supplement this 2015 approved drilling it is recommended that a three phase drill program be undertaken. This drilling would be completed in 2015 and 2016 and would require the creation of a new drill platform on the 760L. The first and second phases of drilling will be undertaken to convert the existing Indicated and Inferred mineral resources to the Measured category between the 805 - 925L and the 925 - 1050L respectively. In this portion of the deposit the mineral resource is dominated by the North A and North A2 Zones. The third phase of drilling would be designed to upgrade the existing Inferred resources, dominated by the North A, North A2, North B and North B2 Zones to the Indicated category between the 1050 — 1300L.

This three phase program would be spread over two years, 2015 and 2016. Phase 1 drilling of 8,300 metres and the first leg of a new drill platform on the 760L (265 m) would be completed in 2015. The 760L drill platform will be required for the Phase 2 drilling. In 2016 the second phase of drilling (10,300 m) would be started early in the year as would the second stage of development (380 m) on the 760L. This development will be required for the Phase 3 drilling campaign (19,000 m) which would be completed in the latter part of 2016.

The following table summarizes the drilling/development metres and costs associated with this recommended program:

Table 26.1:Summary of Costs for 3 Phase Drill Program

Year	Drilling				Development - 760 Level
		Metres	$/m	Cost ($)		Metres	Cost ($)
2015	Phase 1	8,300	90	745,000	Stage 1	265	1,100,000
2016	Phase 2	10,300	100	1,000,000	Stage 2	380	1,500,000
	Phase 3	19,000	100	1,900,000
		37,600		3,645,000			2,600,000

26.1.2Regional Program

While the focus of any drilling should be at the mine, the Bell Creek property includes large sections of untested, favourable stratigraphy and several known gold occurrences that warrant further drill testing. It is recommended that a total of 15,000 metres of drilling at a total cost of $1,500,000 ($100/m) be completed from both underground and surface platforms to test known targets such as Bell Creek -West of Dyke, Wetmore, Stringer and Marlhill East and West.

Technical Report, Bell Creek Mine, 27 March 2015

153

26.2RECONCILIATION

Development of a program of stope reconciliation (block model to stope design to production data to mill reconciliation) has been initiated. One geologist and one engineer working on a part time basis should be utilized to finalize this procedure at an estimated cost of $10,000. The focus should be to finalize this process within one to two months and then to reconcile stopes as they are mined. Previously completed stoping can be reconciled as time permits.

26.3ENGINEERING STUDIES FOR RESOURCE AT DEPTH

The mine design engineering, cost evaluation, and financial analysis completed on the measured and indicated resource pool between 445L and 1165L indicates economic value and therefore substantiates the reserves declared in this report.

The mine design presented in this study supports mining to the 1165L using the ramp as the primary access to the reserves. As this mine plan is being executed, further exploration and study work focusing on the resources at depth (below 1165L) should continue.

Statistical Analysis of Bell Creek Mine QA/QC Assay Data:

For the period - November 2nd, 2012 to December 17th, 2014

1.0          Introduction

This memo describes a review of Lake Shore Gold’s blind quality assurance/quality control (QA/QC) program for underground diamond drilling from the Bell Creek deposit for the period since the last NI 43-101 technical report inclusive from November 2nd, 2012 to December 17th, 2014. This QA/QC program consists of inserting three different types of QC materials into the stream of core samples collected during the drilling programme. The QC types include certified reference material (CRM) or standards, samples of “barren” diabase or blanks and coarse duplicates.

During that time period, a total of 27,490 drill core samples were sent to three different analytical labs, with 42.5%, 36.6%, and 20.9% going to Activation Laboratories (ActLabs), Bell Creek Laboratory, and Accurassay Laboratories respectively. Activation Laboratories is certified under the ISO 9001 standard, and gained 17025 CAN-P-4E accreditation in early 2014. The Bell Creek Laboratory, a Lake Shore Gold operated mine assay lab has, since September 2012 successfully completed the Proficiency Testing Program for Mineral Analysis Laboratories (PTP-MAL), run by the Canadian Certified Reference Materials Project (CCRMP) of Natural Resources Canada (NRCan). Lake Shore Gold discontinued the use of Accurassay Laboratories, also an accredited lab, in May 2013. Table 1.1 summarizes the number of samples sent to the various labs and the number of QA/QC samples used.

2.0          Certified Reference Materials - Standards

From November 2nd, 2012 to December 17th, 2014, 721 CRM samples or standards were sent to assay laboratories for analysis.

Results from a variety of standards from the three labs have been separated and analyzed for the Bell Creek Mine project. The labs used in the time period from November 2nd, 2012 to December 17th, 2014 were as follows: Accurassay Laboratories, Activation Laboratories Ltd., and Bell Creek Laboratory. Summary statistics of standard results have are shown below. Each table lists the following:

·      Target value of standard

·      Standard deviation of CRM samples

·      The minimum / maximum gates of the standard ( +/- 3 standard deviations)

·      The number of results for the standard (Nb)

·      The mean / average result (Average)

·      % relative difference between the mean result and the target (%Diff)

·      The number of results below and above the certified value or target (Nb below and Nb above)

·      The number of results outside the Min/Max gates of the standard (Nb Fail)

·      Percentage of results below and above the target (PBelow and PAbove)

·      Percentage of results outside the Min/Max gates of the standard (Poutside)

Technical Report, Bell Creek Mine, 27 March 2015

Appendix B-2

There were four plausible mislabels (data entry error) of standard O-15d removed from the Accurassay statistics.

ActLabs performed the best for the analysis of standards, having a failure rate of 2.28%, with a total amount of standard being 219, which is the smallest sample size. Bell Creek Lab performed the second best for the standards, having a failure rate of 4.14%, out of 266 samples (the largest sample size). The precision of both ActLabs and Bell Creek Lab are acceptable, according to their failure rates. Accurassay performed the worst of the three labs, having a failure rate of 9.48% out of 232 samples, displaying poor precision. This led to the decision to discontinue use of the lab in May 2013.

In terms of accuracy, all three labs performed well, with average relative differences of 0.22%, -0.05%, and -0.87% for Accurassay, ActLabs, and Bell Creek Lab respectively.

Accurassay Laboratories had an overall good relative difference (0.22%), however most of the individual standards are coming in below the target (62.72%), which could mean that Accurassay could be underestimating the grade. Some of the standards had a small sample size, which may affect the statistics.

It is recommended to use standards with more than 20 results to get a more representative statistical analysis.

ActLabs had the best overall relative difference (-0.05%). The proportions of results below/above the target are relatively close, at 55.25% and 44.75% respectively.

Bell Creek Lab also had a good overall relative difference (-0.87%). The proportion of results below/above the target is also acceptable, 56.20% and 43.80% respectively.

See Tables 2.1 to 2.3 for detailed statistics and Figs. 2.1 to 2.3 for detailed plots for each laboratory.

3.0          Blanks

Results from blanks have also been separated by lab, but in this analysis the percentage of results above a given failure limit is determined. Traditionally in the industry, the cut-off limit is five times the detection limit (0.025 g/t Au). This is in fact quite low; therefore Lake Shore Gold uses a more practical cut-off limit of 0.1 g/t Au. A total of 791 blanks were sent to the various labs.

ActLabs performed the best for blanks. There were 266 blanks sent to ActLabs during the time period, in which none of them failed.

Bell Creek Lab performed second best for the blanks. There were 286 blanks sent, of which two of them failed, giving a failure rate of 0.70%.

Accurassay also performed well for the blanks, having a failure rate of 1.26%.

See Table 3.1 below and Figs 3.1 to 3.3 for a breakdown of the blank statistics.

Table 3.1: Blank Statistics for Each Laboratory Used

Laboratory	Total Blanks	Number > 0.1	% > 0.1
Accurassay Laboratories	239	3	1.26
Activation Laboratories	266	0	0.00
Bell Creek Laboratory	286	2	0.70
ALL	791	5	0.63

4.0          Coarse Duplicates

Coarse duplicates are assays from a new pulp taken from the crushed and ground (but not pulverized) reject of the original sample. There is more variability in the results of coarse duplicates than those of lab or pulp duplicates. A total of 716 coarse duplicates were sent to the various labs, with detailed statistics shown below in Tables 4.1 to 4.3.

ActLabs had the lowest relative difference between means (1.13%), with a correlation coefficient (R) of 0.9941. This indicates a very strong linear relationship between the pairs. A total of 227 coarse duplicate pairs were sent to ActLabs during the time period.

Technical Report, Bell Creek Mine, 27 March 2015

Appendix B-3

The second best performer for coarse duplicate pairs was Bell Creek Lab. A total of 254 pairs were sent, with a relative difference of -2.65% between means. The correlation coefficient for the pairs was 0.9954, which indicates a very strong linear relationship between the pairs.

Accurassay performed the poorest of all labs for coarse duplicates. Out of 234 pairs, there is a relative difference between means of -7.98%. The correlation coefficient for the pairs is 0.8840, which indicates a strong linear relationship, but is not as acceptable as the other two labs.

See Table 4.1 to 4.3 for detailed statistics and Fig. 4.1 to 4.3 for detailed log-normal plots for each lab.

5.0          Check Assays

Lake Shore Gold has performed four rounds of check assay programs where 5% or 10% of original assay pulps from sampling during the period of November 2nd, 2012 to December 17th, 2014 were sent to another laboratory for analysis. The check assay laboratory used for all programs was SGS Canada Inc, an ISO 9001 certified lab. See Table 5.1 below for the number of samples sent to each laboratory within each check assay program period. Statistics were compiled for all samples during the entire time period from the last 43-101 to the current effective date. Ten percent, (instead of the usual 5%) of the pulps from Bell Creek Lab were used for the most recent check assay program, covering June 1st to August 31st, 2014, an extra check as it is the company’s internal mine assay lab.

The same statistics were compiled for the check assays as the coarse duplicates. In this case, results from analysis of a second cut from the same pulp are compared. These analysis are completed at a different lab.

Table 5.1: Total Bell Creek Samples used for each check assay program.

October 1, 2012 to July 31, 2013
Laboratory	# Samples	# Checks

5.1          Accurassay Laboratories vs. SGS Canada Inc.

A total of 318 Accurassay Laboratories pulps were sent for check assay to SGS Canada Inc.

The original Accurassay assay values range from 0.0025 g/t Au to 9.698 g/t Au, and have a mean of 1.018 g/t Au. The check SGS values range from 0.0025 g/t Au to 16.040 g/t Au, and have a mean of 1.080. The relative difference between means is 5.93%, indicating that the SGS pulps tend to come back slightly higher than the original Accurassay values. The correlation coefficient (R) of the pairs is 0.9463, which represents a strongly linear correlation.

See Table 5.1 for detailed statistics and Fig. 5.1 for detailed log-normal plot.

Technical Report, Bell Creek Mine, 27 March 2015

Appendix B-4

5.2          Activation Laboratories vs. SGS Canada Inc.

A total of 437 ActLabs pulps were sent for check assay to SGS Canada Inc.

The original ActLabs values range from 0.0025 g/t Au to 42.500 g/t Au, and have a mean of 2.054 g/t Au.

The check SGS values range from 0.0025 g/t Au to 42.810 g/t Au, and have a mean of 2.037 g/t Au. The relative difference between means is -0.80%. The correlation coefficient is 0.9926, which indicates a very strong linear relationship between the sets.

See Table 5.2 for detailed statistics and Fig. 5.2 for detailed log-normal plot.

5.3          Bell Creek Laboratory vs. SGS Canada Inc.

A total of 458 Bell Creek Lab pulps were sent for check assay to SGS Canada Inc.

The original Bell Creek Lab values range from 0.0025 g/t Au to 16.697 g/t Au, and have a mean of 1.728 g/t Au. The check SGS values range from 0.0025 g/t Au to 19.770 g/t Au, and have a mean of 1.695 g/t Au. There relative difference between means is -1.90%. The correlation coefficient is 0.9598, which indicates a very strong linear relationship.

See Table 5.3 for detailed statistics and Fig. 5.3 for detailed log-normal plot.

6.0          Analytical Lab Internal Standards, Blanks, and Duplicates

No analysis has been completed for this report on the main three analytical labs’ internal QA/QC samples (standards, blanks, or duplicates). This data is routinely reviewed by the drill program QP and database administrator when assay results are received from the respective labs and prior to importation into the database.

7.0          Conclusions

Drill core samples from underground drill holes that were added to the Bell Creek drill database between November 2nd, 2012 and December 17th, 2014 were sent to three analytical labs.

No critical issues were identified for Actlabs or Bell Creek lab that would lead Lake Shore Gold to believe that there is a concern with the analytical results.

Some issues identified with Accurassay (high failure rate for standards and poor coarse duplicate results) resulted in a decision not to use the lab from May 2013 onward.

RESOURCES ESTIMATION VERIFICATION BELL CREEK GOLD DEPOSITS

1INTRODUCTION

The present report was prepared by SGS Canada Inc. — Geostat (hereafter “SGS Geostat”) to support the verification process of the Mineral Resources estimates produced by Lakeshore Gold Corp. (hereafter “LSG”) for the Bell Creek gold deposits (thereafter BC) in December, 2014. LSG mandated SGS Geostat to review the Mineral Resources estimation produced internally in December 2014. The verification included the following points:

1.Summary review of the database and Genesis importation errors;

2.Review of the solids and the limits of the domains with possible risk associated with the limits;

3.Review of the compositing process and capping levels;

4.Review of the interpolation process and its statistical components;

5.Kriging of the most important (in Au ounces) zones with possible estimation errors associated with the interpolation and composites;

6.Review and comments on the Measured category classification;

7.Review of the reported resources tables.

LSG transmitted the data to SGS Geostat during January 2015, which included:

1.Drill hole database (.csv) with Collars, Surveys, Assays and Lithos;

2.Mineralized solids file (.dxf);

3.Composites file (.asc);

4.Block Model file (.txt);

5.ReadMe file (.word) including the models parameters and block model variable details;

6.Resources report for the undepleted block model above given cut off grade.

2DATABASE AND IMPORT ERRORS

In order to conduct the verifications, SGS Geostat imported the data provided by LSG into the Genesis© software. Before importation, the .csv files were validated and modified to adapt to the Genesis© format specifications. Upon importation, Genesis produced an import error file which was used to validate and highlight major discrepancies in the data.

The data transmitted to SGS Geostat included:

1.1,782 valid drill holes;

2.154,196 survey entries;

3.120,535 assays entries;

4.32,661 litho entries;

5.6,150 composites;

6.524,538 blocks.

No major discrepancies were found in the Bell Creek data. The following holes were not imported in Genesis©, because they lacked azimuth or dip entries, however this was explained by LSG. These holes have a collar azimuth and dip of zero with no down hole surveys, which is not properly saved in the survey table by Gems©:

3MINERALIZED SOLIDS REVIEW

The mineralized solids files transmitted to SGS Geostat contained 16 individual solids corresponding to different (exclusive) mineralized zones. Most of the solids validated using the “envelop validation” tool in Genesis©; the ones that did not validate were still functional for the purposes of this Mineral Resources validation. The total volume of the mineralized solid is 5,491,309m2 which matches the block model’s volume (5,464,793m2) using block percentage. The difference between both volumes is 0.5%, which is negligible. The block sized (2m x 3m x 3m) selected by LSG is appropriate given the solids geometry and size. Most blocks (77%) are 100% inside the mineralized solids.

Assays inside and outside of the mineralized solids were grouped by distance to the contacts. Summary statistics of these assays groups (Figure 1) makes it possible to conduct a statistical validation of the mineralized solids. Upon verification, the solids used by LSG seem to delineate the mineralization properly without incorporating too much waste material or leaving mineralized material out. The average Au grade inside the solids is 3.22 g/t (max= 357.33 g/t and min= 0.002) and the average Au grade outside the solids is 0.70 g/t (max= 898.36 g/t and min= 0.001 g/t).

Interpretation of the mineralized solids is done on sections. Since the polylines are tied together using only sections, it is important to validate polyline to polyline connections in plan view. This enables to find displacement and discontinuity in mineralized zones that cannot be seen on sections. SGS Geostat reviewed the solids every 2m and found discontinuities that could affect (very slightly) the tonnage, but most importantly the geometry of the mineralization (Figure 2).

4REVIEW OF THE CAPPING LEVELS

Capping high values, considered to be “extreme” in nature, decreases the importance of these values in the estimation of the average grade (interpolation). Capping is normally carried out to comfort the persons in charge of the resources estimation, but it can affect the overall metal content of a deposit. Hence, it is important to properly select these capping levels so as to not penalize the Mineral Resources estimates while not being over confident. Since assays have varying length and that high values are generally found in short assays length, it is common practice to cap the length grade product values (Au GT).

4.1Bell Creek

At Bell Creek, the 16 individual zones were studied to determine capping levels. Depending on the zones, the capping level varies from 44 g/t to 25 g/t. The metal lost resulting from capping varies from 0.1% to 19% (Table 1). SGS Geostat validated the different capping levels using cumulative frequency graphs and statistical tools and generally agrees with the different capping values used.

It was noted that the capping was applied to the assay’s grades. Since most of the high values are found in short assays length, SGS Geostat recommends conducting capping on normalized assays values (Grade length product GT). This has for effect to normalize the length and also tends to decrease the amount of metal lost from the capping process. Upon capping the GT values, SGS Geostat has found metal lost varying between 0.1% and 13%.

Individual zones were investigated in detail in order improve the capping process. Zone NA_FW was capped at 34 g/t by LSG using un-normalized assays. However, when conducting the capping study on GT values, it is found that a capping level at 46GT could be used and would create a metal lost of 13% which is lower than the actual metal lost of 19%. The same process was conducted for zone HW and SGS Geostat recommends a capping level at 52GT creating a metal lost of 1% compared to the 6% currently used. For all other zones, the capping levels used were similar to the one proposed by SGS Geostat.

5COMPOSITING PROCESS VALIDATION

In order to interpolate the block model, it is customary to composite the samples in order to normalize the length and remove this variable in the weighted average process of interpolation. LSG composites the samples using calculated length which divides the mineralized intersection of a given drill hole into a certain number of composites with length as close as possible to 1m.

5.1Bell Creek Composites

A set of 6,013 composites was transmitted to SGS Geostat by LSG. The composites are tagged according to the mineralized solids they belong to and are used exclusively to interpolate these given zones. The cumulative length of the composites is 6,864m, which closely matches the 6,638m cumulative length of the assays. The average value of the composites is 4.16 g/t and the average value of the assays is 4.19 g/t. The compositing process, as expected, lowers the average values a little and also lowers the variability from 188% to 126%.

6INTERPOLATION PROCESS VALIDATION

In order to estimate the Mineral Resources, LSG interpolated the composites into the block model. The interpolation was accomplished using Inverse Square Distance (ID2) methodology using composites exclusively from a solid to interpolate to blocks of that given zone. Three (3) successive passes with increasing ellipse sizes and broader parameters were used to interpolate the block model. The interpolation process should reproduce the statistical distribution of the composites, hence reflecting the sampling data.

In order to validate the interpolation process, SGS Geostat performed checks of the statistics of different zones, then re-interpolated the blocks using the same parameters and methodology as LSG and finally re-interpolated the blocks using Kriging.

6.1Bell Creek Statistics

For Bell Creek, SGS Geostat selected 4 different zones to validate the block interpolation process. These zones represent roughly 90% of the overall Mineral Resources. The selected are the following:

1.NA (3.891 Mt @ 5.14 g/t);

2.NA2 (1.885 Mt @ 4.10 g/t);

3.NB (2.018 Mt @ 3.85 g/t) and

4.NB2 (1.526 Mt @ 3.32 g/t).

SGS Geostat selected blocks and matching composites (composites located inside a given block) in order to compare their statistical distribution. Normally, the correlation between the composite’s grades and the block’s grade should show a relatively strong correlation. Furthermore, if not too much smoothing is created during the interpolation process, the point cloud should be close to the 1:1 line. At Bell Creek (Figure 3), the composites versus blocks verification did not highlight any major issues with the interpolation process and smoothing seems proper for a Au deposit. The expected decrease of variability and average grade is observed in all 4 zones, but is not too drastic, hence should not affect the geometric distribution of the high and low grade zones.

6.1.1       ID2 Interpolation Validation

Following the statistical verifications for the selected zones, SGS Geostat re-interpolated the block using the same parameters and methodology as LSG. SGS Geostat conducted ID2 interpolation of the grades using the same capping levels and 3 passes with the following parameters:

1.Ellipse: 30m x 15m x 10m oriented: using minimum 9 composites, maximum 18 composites and maximum 6 composites per hole;

2.Ellipse: 60m x 30m x 20m oriented: using minimum 9 composites, maximum 18 composites and maximum 6 composites per hole;

3.Ellipse: 90m x 75m x 55m oriented: using minimum 1 composite, maximum 18 composites and maximum 6 composites per hole.

The use of minimum 1 composite for the last pass of interpolation creates a certain level of extrapolation in the interpolation process. Blocks located in the solids extrapolated interpretations will be estimated from the last point of information, most of the time a high grade sample included in the solid. This generates a higher tonnage of high grade blocks than the probable average grade of that area. These extrapolated parts of the Mineral Resources should always be classified in the inferred category.

The interpolated blocks by SGS Geostat showed a strong geometric correlation and the average grades and tonnages for each zones matched with variation in the 1% ranges for the average grade (Figure 4).

When reporting the block with the 3 re-interpolated zones and above 2.2 g/t Au, SGS Geostat finds a tonnage of 3.45Mt compared to 3.43Mt for LSG (0.6% difference), the average grade for SGS Geostat is 4.68 g/t compared to 4.70 g/t for LSG (-0.4% difference) which translates into a 0.2% difference in Au ounces.

6.1.2       Validation using Kriging

Kriging was used by SGS Geostat to verify the validity of using ID2 methodology for block interpolation. Kriging tends to smooth the values a little more than ID2, but the use of variography to weight the composites values in the block interpolation reflects the natural variance of the deposit.

Upon conducting the variography for all composites, SGS Geostat adjusted the model for each individual zone, varying the sills and ranges of the general variogram. However, the general variogram validates the search ellipses used by LSG. The maximum range of the variogram is 30m, which agrees with the 2 first passes (15m x 30m and 30m v 60m) used by LSG. Blocks estimated in these 2 first passes (50% of the blocks) should reflect the variance properly. However, variography has shown that the model is isotropic; hence search ellipses should be of equal distances in all directions. SGS Geostat would recommend changing the search ellipses to:

1.     First Pass: 20m x 20m x 20m;

2.     Second Pass: 40m x 40m x 40m and

3.     Third Pass: 90m x 90m x 90m.

RESOURCES ESTIMATION VERIFICATION BELL CREEK GOLD DEPOSITS

Upon interpolating the 3 test zones using LSG composites and same search parameters, SGS Geostat does not find any major differences in tonnages, grades special distributions of the grades (Figure 4). No significant difference is observed between SGS and LSG interpolation using the same composites, parameters and search ellipses but different interpolation method (Ordinary Kriging). SGS produces more tonnage by 3.3% and LSG produces better average grade by 1.6% which combined affect the Metal content by 1.8%. This is considered to be acceptable. Ordinary Kriging decreases influence of grade with distances according to continuity, which is translated by more smoothing and more tonnage of grade <5 g/t Au. This shows that ID2 and Kriging are equivalent in interpolating the Mineral Resources for Bell Creek, but ID2 seems to do a better job at representing natural variation in the assays population. Furthermore, the increase level of smoothing could impact the geometry distribution of the high grade zone by incorporating too much smoothing and penalising possible stopes.

7      MINERAL RESOURCES CLASSIFICATION VALIDATION

The Mineral Estimates are classified by LSG using the different search ellipses and passes in which the blocks are interpolated. LSG mandated SGS Geostat to review the measured classification of blocks in the NA zone.

Blocks are classified as measured, where mining developments exist and where blocks were interpolated with first pass and 18 composites (Figure 5). SGS Geostat conducted Irregular Kriging on the block models from the different classifications. The measured category shows a precision of 6.3% in its estimation, the indicated category shows a precision of 13.5% and the inferred category shows a precision of 23.3%. SGS Geostat feels that these precision levels for the different categories are acceptable and reflect the variography model of the data.

Figure 5: Mineral Resources classification by LSG

SGS Geostat is also of the opinion that the measured and indicated categories could be increased slightly and classified using automated functions. The classification of Mineral Resources for the Bell Creek deposit could be classified as following:

1.Measured resources to general areas where interpolation is conducted in the first pass using 18 composites or the presence of working development. Automated classification could use 3

holes inside 30m maximum range (3 holes for 2,830 m2), translating to an approximate influence radius of 17m for each holes;

2.Indicated resources to general areas where interpolation is conducted within the second pass using 18 composites. Automated classification could use 3 holes inside 60m maximum range (3 holes for 11,300 m2), translating to an approximate influence radius of 34m for each holes.

3.All other blocks should be classified as Inferred.

The resulting classification of the Mineral Classification by automated methodology followed with manual solids interpretation (Figure 6) results in an increase of 42% in the measured resources category and only changes the precision of the estimate by 0.7%. The precision levels of the grade estimates are of 7% for the proposed measured category, 16% for the proposed indicated category and 20% for the inferred category.

8MINERAL ESTIMATES REPORT VALIDATION

The Mineral Estimates are reported by LSG using a cut off grade, classification, varying densities and block percentages. The reports are produced in Gems© using different profiles. In order to validate the reports from Gems©, SGS Geostat imported the block model into Access and created Mineral Estimates queries, using the same parameters as LSG.

8.1Bell Creek

The Bell Creek Mineral Estimate is reported above 2.2 g/t for blocks in the Measured, Indicated and Inferred categories (Table 2). Following a zone by zone verification, SGS Geostat did not find any major discrepancies in the Mineral estimates reports at Bell Creek. The block model transmitted to SGS Geostat comprised blocks of measured category in HW2, NA, NA3, NA4, NAFW, NAHW and NB2 zones. LSG only reports measured resources in the NA zone, the blocks from other zones classified as measured were transposed to the indicated category.

Following its verification and validation process for the Bell Creek deposits, SGS Geostat agrees with the Mineral Estimates for this deposit. No major discrepancies are observed in the database, mineralized solids, capping levels, composites, block interpolation and reports.

The Mineral Resources estimates conducted by LSG are correct and done accordingly with the Industry’s Best Practices and Standards.

Minor recommendations are made by SGS Geostat in order to increase the high level of work currently done in the Resources Estimation process for the Bell Creek deposit.

1.Conduct capping study using Au GT (length normalized samples). This method does not affect the number of capped composites but lowers the overall metal lost;

2.Remain cautious with high Au values during capping and interpolation process. At the moment, ID2 produces comparable tonnages and grades to Ordinary Kriging, but does a better job at representation of the high grade variance.

3.Adjusting the search ellipses to illustrate the isotropic nature of the variography model.

Introduction

Lake Shore Gold Corp. (LSG) has updated the 2015 budget and Life of Mine (LOM) plans for Bell Creek Mine. LSG has engaged Stantec Consulting Ltd. (Stantec) to complete a review of the mining plans and comment on the estimated tonnes, grade, and ounces of gold mined to surface (i.e. the reserves). The reserves have been based on measured and indicated resource material only.

Executive Summary

The estimated reserves for Bell Creek Mine are based on the resource models provided by LSG. During the review of mining shape wireframes, adjustments suggested by Stantec were considered and adapted by LSG mine planning personnel. The final stope shapes represent a reasonable mining reserve.

Dilution and mining recovery factors are reasonable and results from stope reconciliation efforts should continue to be used to build up the database for future reserves estimates.

The proposed mining methods have been used successfully at Bell Creek and will continue to be suitable for future mining. A three dimensional mine design has been prepared and development designs and quantities appear suitable to facilitate mining extraction.

The LOM schedule appears to be of sufficient detail to support the reserves.

Mine design quantities from the three dimensional mine model have been used in the development schedule and for cost estimating. The capital and operating costs and productivities used in the mine plan as the basis for estimating the reserves have been based on actual performance metrics of the operation in 2012 through 2014. The LOM capital and operating costs are reasonable and cash flows (based on gold price assumptions) support the reserves.

·      Dilution (planned and unplanned) and mining recovery factors.

·      Mining method(s) and lateral development.

·      Mining shapes (i.e. stope shapes).

Review the life of mine schedule including;

·      Development and stoping activity productivities.

·      Stoping sequence.

Review the estimated LOM capital and operating costs and cash flow.

In-Situ Measured and Indicated Resource

The in-situ measured and indicated resource at 3.0 g/t Cut-off Grade (COG) was used by LSG as an initial indication of the resource that will be targeted for inclusion in reserves (i.e. areas where stope wireframes will be generated and evaluated).

The Bell Creek Block Model “BC_2014_DEC17_DEPLETED_M125.txt” was provided to Stantec on February 19, 2015. Stantec queried the block model to confirm the in-situ resource figures reported by LSG.

The block model includes in-situ measured and indicated material at depths below the current mining plans (i.e. below 1165 Level). However, the resource targeted for production is above 1165 Level. For Stantec’s evaluation only material between 1165 Level (1124 Elevation) and surface was considered.

Estimated Reserves

LSG developed a preliminary mining plan to estimate COGs to use for LOM planning. The Incremental, Marginal, and Overall Mine Economic COGs are summarized in Table 1.

Table 1 — Incremental, Marginal, and Overall Mine Economic COG

Item	Value
Mine Operating and Site General Costs	$77.0 / tonne
Mill Operating Cost	$22.0 / tonne
Mill Recovery	94.5%
Gold Price ($US)	$1,100
Exchange Rate	0.90
Gold Price ($CAD)	$1,225 / ounce
Incremental Cut-Off Grade	2.7 g/t
Sustaining Capital Cost	$35.0 / tonne
Marginal Cut-Off Grade	3.6 g/t
Risk adjusted Rate of Return	15%
Overall Mine Economic Cut-Off Grade	4.2 g/t

Appendix E-3

To estimate the reserves, LSG mine planning personnel generate stope wireframes within potential mining areas and query the block model within the wireframe. The wireframes include any “low grade” and/or waste rock within the confines of the shapes (commonly referred to as “planned dilution”). Unplanned dilution and mining recovery factors are then applied to the in-situ wireframe to estimate the tonnes, grade, and ounces that will be mined.

Unplanned dilution parameters for reserves have been estimated for each stope based on the depth of failure of the hangingwall and footwall. The depth of failure varies with the dip of the surface. The assumptions for hangingwall and footwall dilution are shown in Table 2.

Table 2 — Bell Creek Dilution Assumptions

Source	Dip
	50° - 60°	60° - 70°	70° - 80°	80° - 90°
Hangingwall Dilution (m)	0.45	0.40	0.30	0.20
Footwall Dilution (m)	0.45	0.40	0.30	0.20

Based on data for stopes planned from 2015 to the end of the mine life, the estimated average unplanned waste rock dilution will be 13.5% added to the stope design tonnes.

In addition, unplanned backfill dilution from the floor and exposed fill walls has been added as required for each stope. The estimated average unplanned backfill dilution is 0.87% added to the stope design tonnes.

There will be approximately 193,000 tonnes and 32,000 ounces of in-situ measured and indicated resource left behind in sill pillars. Where stopes are wider and the pillar height becomes larger some suggested strategies to recover some of this resource might include:

·Geomechanical analysis to determine if a reduced sill pillar height is achievable.

·Trade-off study for the possible use of consolidated fill in wider areas to increase recovery.

·Trade-off study to evaluate mining narrower stopes to reduce the pillar height.

For Bell Creek a mining recovery factor of 95% has been applied to account for resource that is planned to be mined, but is not recovered due to mining process inefficiencies. Going forward, stope CMS and dilution analysis should continue to be completed on all stopes to support dilution and recovery assumptions.

The “BC Reserves 2015 v7” Excel file (received from LSG) provides a detailed breakdown of the estimated reserves mined in 2015 through to the end of mine life. The breakdown is summarized in Table 3. It should be noted that some of the reserve ounces reported in Table 3 and in “BC Reserves 2015 v7” are below 3 g/t. This is because some low grade material (i.e. planned dilution) must be mined to capture the material in a stope above COG.

	Tonnes	Grade (g/t)	Ounces
Proven	172,200	4.5	24,860
Probable	1,620,100	4.6	238,750
Total Bell Creek	1,792,300	4.6	263,610

Mining Shapes

The mining shapes used to estimate the reserves for Bell Creek were reviewed. The shapes appeared to be mineable and have an adequate mine development plan for extraction.

As stopes near production, the stope shape will be revised/optimized a number of times right up to the last stages of design when LSG mine planning personnel complete the drilling layouts. The changes in the stope reserve from the LOM shapes to budget shapes to final stope design to final mined out stope cavity monitor survey should continue to be tracked for future reconciliation purposes.

Life of Mine Schedule

A life of mine (LOM) schedule has been prepared by LSG using Microsoft Project. All LOM development and production activities are scheduled using quantity take-offs from the three-dimensional mine design model and stope reserves data. Operating experience has been used for estimating productivities. Data from the Microsoft Project schedule is transferred into Microsoft Excel for distributing quantities over time for cost estimating.

The schedule appears to be of sufficient detail to support the estimated reserve.

Economic Assessment

LSG estimated the LOM capital and operating costs and completed an economic assessment of the reserves. Overall economics factor in a rate of return and profitability. A LOM cash flow has been completed to demonstrate that the proven and probable reserves support the operating and capital costs. The capital and operating costs and productivities have been based on actual performance metrics of the operation in 2012 through 2014. The LOM capital and operating costs are reasonable and cash flows (based on gold price assumptions) support the reserves.
