The following factors for converting Imperial measurements into metric equivalents are provided:

In this AIF, the following capitalized terms have the defined meanings set forth below:

The discussion of mineral deposit classifications in this AIF adheres to the resource/reserve definitions and classification criteria developed by the Canadian Institute of Mining and Metallurgy in 2005. Estimated mineral resources fall into two broad categories dependent on whether the economic viability of them has been established and these are namely “resources” (economic viability not established) and ore “reserves” (viable economic production is feasible). Resources are sub-divided into categories depending on the confidence level of the estimate based on level of detail of sampling and geological understanding of the deposit. The categories, from lowest confidence to highest confidence, are inferred resource, indicated resource and measured resource. Reserves are similarly sub-divided by order of confidence into probable (lowest) and proven (highest). These classifications can be more particularly described as follows:

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 reasonable prospects 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.

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 gathered through appropriate techniques from locations such as outcrops, trenches, pits, workings and drill holes.

An “Indicated Mineral Resource” is that part of a 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.

A “Measured Mineral Resource” is that part of a 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 application of technical and economic parameters, to support production planning and evaluation of 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.

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

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.

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, that economic extraction is justified. The U.S. Securities and Exchange Commission require permits in hand or their issuance imminent to classify mineralized material as reserves.

CAUTIONARY NOTE TO UNITED STATES INVESTORS CONCERNING ESTIMATES OF RESERVES AND MEASURED, INDICATED AND INFERRED RESOURCES

The disclosure in this AIF, including the documents incorporated by reference herein, uses terms that comply with reporting standards in Canada and certain estimates are made in accordance with Canadian National Instrument 43-101 Standards of Disclosure for Mineral Projects (“NI 43-101”). NI 43-101 is a rule developed by the Canadian Securities Administrators that establishes standards for all public disclosure an issuer makes of scientific and technical information concerning mineral projects. Unless otherwise indicated, all reserve and resource estimates contained in or incorporated by reference in this AIF have been prepared in accordance with NI 43-101. These standards differ significantly from the requirements of the SEC, and reserve and resource information contained herein and incorporated by reference herein may not be comparable to similar information disclosed by U.S. companies.

This AIF includes mineral reserve estimates that have been calculated in accordance with NI 43-101, as required by Canadian securities regulatory authorities. For United States reporting purposes, SEC Industry Guide 7 (under the United States Securities Exchange Act of 1934 (the “Exchange Act”)), as interpreted by Staff of the SEC, applies different standards in order to classify mineralization as a reserve. As a result, the definitions of proven and probable reserves used in NI 43-101 differ from the definitions in the SEC Industry Guide 7. Under SEC standards, mineralization may not be classified as a "reserve" unless the determination has been made that the mineralization could be economically and legally produced or extracted at the time the reserve determination is made. Among other things, all necessary permits would be required to be in-hand or their issuance be imminent in order to classify mineralized material as reserves under the SEC standards. Accordingly, certain mineral reserve estimates contained in this AIF may not qualify as “reserves” under SEC standards, unless expressly stated to so qualify.

In addition, this AIF uses the terms “measured mineral resources”, “indicated mineral resources” and “inferred mineral resources” to comply with the reporting standards in Canada. We advise investors that while those terms are recognized and required by Canadian regulations, the SEC does not recognize them. Investors are cautioned not to assume that any part or all of the mineral deposits in these categories that are not already classified as “reserves” will ever be converted into mineral reserves. These terms have a great amount of uncertainty as to their existence, and great uncertainty as to their economic and legal feasibility.

Further, “inferred resources” have a great amount of uncertainty as to their existence and as to whether they can be mined legally or economically. Therefore, Investors are also cautioned not to assume that all or any part of the inferred resources exists. In accordance with Canadian rules, estimates of “inferred mineral resources” cannot form the basis of feasibility or other economic studies.

It cannot be assumed that all or any part of “measured mineral resources”, “indicated mineral resources”, or “inferred mineral resources” will ever be upgraded to a higher category. Investors are cautioned not to assume that any part of the reported “measured mineral resources”, “indicated mineral resources”, or “inferred mineral resources” in this AIF that are not already classified as “reserves” is economically or legally mineable.

In addition, disclosure of “contained ounces” in respect of resources that do not qualify as reserves is permitted disclosure under Canadian regulations; however, the SEC only permits issuers to report reserves in ounces and requires other mineralized material to be reported as in place tonnage and grade without reference to unit measures.

For the above reasons, information contained in this AIF and the documents incorporated by reference herein containing descriptions of our mineral deposits may not be comparable to similar information made public by U.S. companies subject to the reporting and disclosure requirements under the United States federal securities laws and the rules and regulations thereunder.

Taseko Mines Limited was incorporated on April 15, 1966, pursuant to the Company Act (British Columbia). This corporate legislation was superseded in 2004 by the British Columbia Business Corporations Act which is now the corporate law statute that governs us. Our registered office is located at Suite 1500, 1055 West Georgia Street, Vancouver, British Columbia, V6E 4N7, and our head office is located at Suite 1500, 1040 West Georgia Street, Vancouver, British Columbia, V6E 4H1.

^1.Taseko owns 100% of Gibraltar Mines Ltd., which owns 75% of the Gibraltar Joint Venture
^2.Taseko owns 100% of Curis Resources Ltd., which owns 100% of Curis Holdings (Canada) Ltd., which owns 100% of Florence Copper Inc.

On March 31, 2010, we established by two contracts an unincorporated joint venture (“JV”) between Gibraltar Mines Ltd., and Cariboo Copper Corp. (“Cariboo”) over the Gibraltar copper and molybdenum mine (the “Gibraltar Mine”), whereby Cariboo acquired a 25% interest in the Gibraltar Mine and we retained a 75% interest with Gibraltar Mines Ltd. operating the mine for the two JV participants. Under the related Joint Venture Formation Agreement (“JVFA”), the Company contributed to the Joint Venture substantially all assets and obligations pertaining to the Gibraltar Mine, and Cariboo paid the Company $187 million to obtain its 25% interest in the JV. Gibraltar Mines Ltd. continues to be the operator of the Gibraltar Mine under the Joint Venture Operating Agreement which is filed at www.sedar.com. Cariboo is a Japanese consortium jointly owned by Sojitz Corporation (50%), Dowa Metals & Mining Co., Ltd. (25%) and Furukawa Co., Ltd. (25%).

Taseko is a Vancouver, B.C. headquartered mining company that has been focused on the operation of the Gibraltar Mine, and on the development of the New Prosperity gold and copper project, the Aley Niobium project, and the Florence Copper project. All of these properties are located in British Columbia, Canada except for the Florence Copper project which is located in Arizona. The following is a summary of the development of our business over the last three financial years:

The second concentrator at the Gibraltar Mine, which completed commissioning in March 2013, completed its first full year of operations.

On February 26, 2014, the Minister of the Environment announced her conclusion that the New Prosperity project is likely to cause significant adverse environmental effects. The Minister referred the matter to the Governor in Council who decided that those effects are not justified in the circumstances and accordingly the mine could not proceed.

On March 26, 2014, the Company filed an application for judicial review in Federal Court, seeking to quash (invalidate) the decisions of the Minister and Governor in Council communicated on February 26, 2014. The Company also sought a declaration that certain sections of the Canadian Environmental Assessment Act, 2012, are in whole or in part beyond the powers of the Federal government under the Constitution Act, 1867.

In September 2014, the Company announced a NI 43-101 compliant reserve estimate for the Aley Niobium project of 84 million tonnes grading 0.50% ^Nb2^O5^{. The reserve estimate is}documented in a technical report entitled “Technical Report on Mineral Reserves at the Aley Project” dated October 30, 2014, prepared by Scott Jones, P.Eng., Keith Merriam, P.Eng., Greg Yelland, P.Eng., Robert Rotzinger, P.Eng., and Ronald G. Simpson, P.Geo.

On November 20, 2014, the Company acquired a 100% interest in the Florence Copper Project though the acquisition of Curis Resources Ltd. (“Curis”). The aggregate value of the consideration for the acquisition of Curis was approximately $85 million inclusive of debt assumed. The Florence Copper Project is an in-situ copper recovery and solvent extraction/electrowinning project located near the town of Florence in central Arizona, USA.

In May 5, 2015, the Company completed an updated mine plan for the Gibraltar Mine featuring a 50% decrease in strip ratio and a reduced cut-off grade, achieving an overall reduction in copper production costs with a slightly lower amount of copper produced. The new mine plan was a result of a detailed, six-month engineering study and forms the basis of an updated NI 43-101 compliant reserve. The reserve estimate is documented in a technical report entitled “Technical Report on Mineral Reserve Update at the Gibraltar Mine” dated June 15, 2015, prepared by Taseko and Gibraltar Mine staff under the supervision of Scott Jones, P.Eng., a Qualified Person under NI 43-101.

On January 14, 2015, the British Columbia Minister of Environment granted the Company a five-year extension to the New Prosperity Environmental Assessment Certificate.

The two remaining permits required for construction and operation of the Florence Copper production test facility were issued in August and December 2016, respectively.

On February 12, 2016, Taseko announced that it had filed a civil claim in the B.C. Supreme Court against the Canadian federal government. The claim seeks damages in relation to the February 26, 2014 decision of the Minister of the Environment concerning the New Prosperity Project in that the Government of Canada and its agents failed to meet the legal duties that were owed to Taseko and that in doing so they caused and continue to cause damages, expenses and loss to Taseko.

Taseko has been proceeding with its request to amend the British Columbia environmental assessment certificate for the New Prosperity Project. In addition, Taseko has filed a Notice of Work (“NOW”) with the Ministry of Energy & Mines which will allow the Company to gather information to advance mine permitting under the Mines Act of British Columbia.

On January 16, 2017, the Company announced that completed technical work on the Florence Copper Project has resulted in a significant improvement in project economics. The results are described in the report titled “NI 43-101 Technical Report, Florence Copper Project, Florence, Pinal County, Arizona” dated February 28, 2017, prepared by Dan Johnson, P.E., RM-SME, a Qualified Person under NI 43-101, and is filed on www.sedar.com.

On February 27 2017, the Company announced that it has entered into a US$33 million streaming agreement with Osisko Gold Royalties Ltd (“Osisko”) for Taseko’s 75% share of payable silver production from the Gibraltar Mine. Under the terms of the streaming agreement, Taseko has received an upfront deposit of US$33 million for 100% of its share of Gibraltar payable silver production until 5.9 million ounces have been delivered. After that threshold has been met, 35% of Taseko’s share of all future silver production will be delivered to Osisko. Osisko will pay US$2.75 per ounce for all the silver deliveries made under the streaming agreement. Additionally, Osisko has been granted warrants for three million common shares of Taseko with a strike price of $2.74 per common share. The warrants will expire on April 1, 2020.

The two Judicial Reviews initiated by Taseko were heard in federal court over a five day period in the week of January 30, 2017 for the New Prosperity Project. Both Judicial Reviews focus on the fundamental principles of administrative and procedural fairness. Taseko alleged that the Government of Canada, through the conduct of the environmental assessment and the decisions which resulted from it, failed in its obligation to uphold those fundamental principles. A decision is expected from the federal court within six to nine months.

Taseko is a mining company that seeks to acquire, develop, and operate large tonnage mineral deposits which, under conservative metals price assumptions, it believes are potentially capable of supporting a mine for 10 years or longer.

Our principal business activity is operating the Gibraltar Mine and advancing our other projects to a production decision. In recent years, we have expanded the Gibraltar Mine ore concentrator, added a second ore concentrator, increased the mining fleet and made other production improvements at the mine. Our business is focused on the production of copper and molybdenum from the Gibraltar Mine and on securing environmental permits for the proposed Florence Copper Project, Aley Niobium Project and the New Prosperity gold and copper project. The Company also owns the Harmony gold project, an exploration stage gold property on BC’s West Coast.

All projects are operated solely by Taseko directly or through subsidiaries and are 100% owned, except the Gibraltar Mine which is 75% owned.

The map below highlights the location of the Company’s four properties in British Columbia, Canada and one property in Arizona, USA:

Taseko’s assets include reserves and resources in a diverse range of metals including copper, molybdenum, gold and niobium. Demand for these metals fluctuates in tandem with general global economic conditions.

Taseko’s strategy has been to grow the Company by utilizing cash flow from the Gibraltar Mine to assemble and develop a pipeline of projects. We continue to believe this will generate the best, long-term returns for shareholders. Total expenditures on projects in 2016 consisted of $5.0 million at the Florence Copper project, $1.7 million on New Prosperity, and $0.8 million on the Aley Project.

Following a period of mine expansion and capital expenditure, Gibraltar has now achieved a stable level of operations and the Company’s focus is on further improvements to operating practices to reduce unit costs. Improvement of operating costs were due to cost control initiatives which were implemented during 2015, including mine plan modifications, workforce reductions and vendor initiatives. During September 2016, the molybdenum circuit at Gibraltar was successfully restarted, and will continue to contribute by-product credits in future periods.

A long-term off-take agreement, signed in the fourth quarter of 2015, has resulted in lower treatment and refining costs. Under the agreement, the Company has committed to sell 600,000 tonnes of Gibraltar copper concentrate (approximately 50% of expected production) through to the end of 2020. The Company also entered into a long-term fixed rate ocean freight contract in early 2016.

During 2016, volatility of commodity prices has continued, with notably stronger copper prices in late 2016.

The average price of London Metals Exchange (“LME”) copper was US$2.39 per pound in the fourth quarter of 2016, which was 11% higher than the third quarter of 2016 and about 8% higher than the fourth quarter of 2015.

The Canadian dollar exchange rate has continued to remain at a substantial discount to the US dollar. A weak Canadian dollar contributes to improved operating margins at Gibraltar as approximately 80% of mine operating costs are paid in Canadian dollars.

Taseko’s mining, exploration and development activities in Canada are subject to various levels of Canadian Federal and British Columbia Provincial laws and regulations relating to the protection of the environment. Similarly, the Florence Copper Project is subject to various levels of US Federal and Arizona State laws and regulations relating to protection of the environment. All of the jurisdictions include requirements for closure and reclamation of mining properties as part of their regulatory framework.

The total liability for reclamation and closure cost obligations as calculated for financial disclosure purposes, at December 31, 2016 was $98.5 million. This amount represents the present value of the estimated future costs of planned and anticipated closure and remediation activities, assuming a pre-tax discount rate of 2.3% and an inflation rate of 2%.

Taseko is committed to continual improvement towards the protection of human health and the stewardship of the environment. Taseko recognizes that responsible environmental management is critical to our success and has committed that it will:

Taseko is a member of the Mining Association of Canada and the Mining Association of British Columbia. Both of these organizations require members to participate in a program known as Towards Sustainable Mining (“TSM”) which encourages companies to work towards best management practice standards through self-regulation and reporting on key performance areas. These areas include:

In 2015, Taseko and Gibraltar’s performance and reporting on performance in all of the areas was verified by an external auditor as being at a level of industry best practice. Further details can be found on the Taseko website.

As at December 31, 2016, the Company had the following employees and contractors:

Taseko provides safe and healthy working conditions, and to establish operating practices which safeguard employees and physical assets.

For the third straight year (2016), Gibraltar has received the John Ash Safety Award presented by the Ministry of Energy and Mines. This prestigious award goes to the mining operation in British Columbia with the lowest injury-frequency rate that has worked at least one million hours during the year.

Unless stated otherwise, information of a technical or scientific nature related to the Gibraltar Mine contained in this AIF (including documents incorporated by reference herein) is summarized or extracted from a technical report entitled “Technical Report on the Mineral Reserve Update at the Gibraltar Mine” dated June 15, 2015 (the “Gibraltar Technical Report”), prepared by Scott Jones, P. Eng. filed on Taseko’s profile at www.sedar.com and updated with production and development results since that time. Mr. Jones is employed by the Company as Vice-President, Engineering and is a “Qualified Person” as defined by Canadian securities regulatory instrument NI 43-101.

The Gibraltar open pit mine and related facilities are located 65 kilometres north of the town of Williams Lake and are centered at latitude 52^o30’N and longitude 122^o16’W in the Cariboo Mining Division. Williams Lake is approximately 590 kms north of Vancouver, British Columbia.

Access to the Gibraltar Mine from Williams Lake is 45 kilometres via Highway 97 to McLeese Lake, and then 20 kilometres by paved road to the mine site.

The Gibraltar Mine property consists of 243 tenures held as summarized in Table 1 below.

There are 32 mining leases at the Gibraltar Mine which are valid until at least October 2033 as long as renewal fees, which are due on an annual basis, are paid. Rights to use the surface accompany each mining lease. There are 211 claims included in the Gibraltar property tenure package. 76 of these claims are due to expire in November 2017, and the remainder are due to expire in May 2021 or later. It is intended that all leases and claims will be renewed prior to their renewal fees being due (in the case of the leases) and prior to their expiry in the case of the claims.

There are several land parcels for which surface rights were purchased outright. There is one fee simple lot at the Gibraltar Mine on which the plant site is located and annual taxes are paid. In addition, the Gibraltar Mine holds three other land parcels.

There are no royalties, overrides, back-in rights, payments or other agreements to which the project is subject.

There are no significant factors or risks that might affect access or title or ability to perform work on the property.

In 1964, Gibraltar acquired a group of claims in the McLeese Lake area from Malabar Mining Co. Ltd. Canadian Exploration Limited (“Canex”) and Duval Corporation (“Duval”) had also been exploring on adjacent claims known as the Pollyanna Group. In 1969, Gibraltar, Canex and Duval entered into an agreement providing for the commingling of Gibraltar’s claims with the Pollyanna Group. In 1971, Gibraltar acquired Duval’s remaining interest in the property.

Preliminary development of the Gibraltar Mine began in October 1970. The concentrator commenced production in March, 1972 and was fully operational by April 1972. A cathode copper plant with an annual capacity of 10 million pounds of market-ready copper metal began operation in October 1986.

In October 1996, Westmin Resources Limited (“Westmin”) acquired 100% control of Gibraltar and in December 1997, Boliden Limited Westmin (Canada) Limited (“Boliden”) acquired Westmin. In March 1998, Boliden announced that it would cease mining operations at the Gibraltar Mine at the end of 1998.

In July 1999, Taseko’s subsidiary, Gibraltar Mines Ltd., purchased the Gibraltar Mine assets from Boliden and certain of its affiliates, including all mineral interests, mining and processing equipment and facilities, and assumed responsibility for reclamation obligations.

From 1999 to 2004, Taseko geologists and engineers sought to better define known resources and explored for additional mineralized material. The on-site staff completed on-going reclamation work and maintained the Gibraltar Mine for re-start. Operating and environmental permits were kept in good standing. The mine re-opened in October 2004. Copper cathode production at the SX/EW plant recommenced in January 2006.

The Gibraltar Mine has been owned and operated as an unincorporated joint venture between Taseko and Cariboo since March 31, 2010. The Company’s wholly- owned subsidiary, Gibraltar Mines Ltd. and Cariboo hold 75% and 25% beneficial interests in the Joint Venture, respectively.

Gibraltar increased design mill capacity to 55,000 tons per day in 2011. Gibraltar further increased design mill capacity to 85,000 tons per day in 2013 through installation of a complete independent second concentrator and a stand-alone Molybdenum Separation Plant.

Total production since 1972 is 557 million tons of ore producing 2.9 billion pounds of copper in concentrate, 102 million pounds of cathode copper and 32 million pounds of molybdenum.

The Gibraltar deposits are hosted by the upper Triassic Granite Mountain batholith, located within a wedge of Mesozoic and Palaeozoic rocks bounded on the west by the Fraser Fault system and on the east by the Pinchi Fault system. The Granite Mountain Batholith is a composite body consisting of three major phases; Border Phase diorite, Mine Phase tonalite, and Granite Mountain trondjhemite. Contacts between the major phases are gradational over widths ranging from two metres to several hundred metres. The regional deformation was accompanied by localized metasomatic alteration and associated sulphide deposition that led to the concentration of copper mineralization in specific areas of the batholith.

There are currently five defined mineralized zones on the Gibraltar Mine property. They are the Pollyanna, Granite, Gibraltar, Connector, and Extension zones. They occur in a broad zone of shearing and alteration.

Two major ore structure orientations have been recognized; the Sunset and Granite Creek systems. Ore host structures of the Sunset system are mainly shear zones, with minor development of stockworks and associated foliation lamellae whereas oriented stockworks with associated pervasive foliation lamellae predominate in the Granite Creek system.

Pyrite and chalcopyrite are the principal primary sulphide minerals. Small concentrations of other sulphides are present in the Gibraltar ores with molybdenite being a minor but economically important associate of chalcopyrite in the Pollyanna, Granite, and Connector deposits.

There has been no material non-drilling exploration conducted on the Gibraltar property since 2000.

A property-scale Induced Polarization (“IP”) geophysical survey was designed and initiated in August 2000. Field activities included 237 kms of line cutting and some 220 kms of IP survey. Several deposit scale anomalies external to current reserves were identified and drill tested in 2003 as described in a report titled “Technical Report on the Gibraltar Mine, British Columbia” by James W. Hendry, P.Eng., and C. Stewart Wallis, P.Geo., dated March 23, 2005, which is filed on www.sedar.com.

From 1999 to 2004, Taseko geologists and engineers sought to better define known resources and explored for additional mineralized material. A core drilling program for pit definition for the Granite Lake and PGE Connector deposits and property exploration at the 98 Oxide Zone was carried out between September and November 2005. A further drilling program carried out in 2006 was designed to define the mineral resources between the existing pits by tying together the extensive mineralization zones, and to test for additional mineralization at depth.

The 2007 program tested a number of targets to define further mineralization, provided definition drilling in the Pollyanna-Granite saddle zone and Granite West areas and included condemnation drilling for the proposed extensions of both the #5 and #6 Dump footprints. The targets for further mineralization were Gibraltar South, Pollyanna North IP anomaly, Granite South and the Gunn Zone.

The 2008 exploration program was conducted on the southern and eastern margins of the Gibraltar pit and northwest of the Gibraltar West pit. The objective was to upgrade identified inferred resources to indicated or measured categories through “in-fill” drilling. Holes drilled in the Gibraltar West pit area were incorporated into the 2008 reserve estimate for the new Gibraltar Extension Pit.

The 2010 program was conducted on the northern and western margins of the Gibraltar pit, and one hole on the southwest margin. The objective was to define the ultimate limit of the Gibraltar pit to the north and west. The 2010 drilling program met the objective of delineating mineralization to the north and west of the Gibraltar pit. A total of 28,129 feet was drilled in 34 drill holes in 2010.

The 2011 program was aimed at identifying mineralization down-dip of the Gibraltar and Granite deposits. A total of 12,229 feet were drilled in 5 holes. A deep zone of anomalous copper ± molybdenum mineralization encountered in drill-hole 2011-003 extends from approximately 2,600 to 3,700 feet and consists of intermittent intercepts grading up to 1.3% TCu and 0.4% Mo.

In 2013, there were two drill programs completed, one in the summer and the other in the fall. Both programs targeted the projected mineralization south of the current Granite pit. A total of 38,068 feet in 31 holes were drilled between the two programs. The objective of both programs was to increase the extent of the mineralization within two of the Granite pit pushbacks.

In early spring of 2014, a resource drill program commenced targeting the Connector pit and the area between Gibraltar East and Granite Pit. At the same time a geotechnical drill program was undertaken. A total of 38 holes between the two programs were drilled with a cumulative length of 37,456 feet. The main goals of the drilling programs were (1) to collect high-quality geological, geotechnical and assay data, (2) to improve the geological understanding of the ore body, and (3) to increase the drill density within and confidence level of the resource model.

In late 2015, one exploration drill hole was drilled to expand the current known mineralization northwest of the Extension deposit. The total depth of the hole was 2,507 feet. A significant interval of copper was encountered at above reserve grade. The mineralization to the west, northwest and at depth is open. More drilling is needed to confirm if the Extension pit can be expanded to include this material.

In 2016, two drill programs were completed. The first program targeted the conversion of resource material from inferred to measured/indicated at the Granite and Pollyanna deposits. The program drilling also allowed an improvement of the geological understanding of the ore bodies. This reserve definition program totaled 35 holes with a cumulative length of 29,342 feet. The second program was an exploration program that targeted the extension of the mineralization discovered in the 2015 exploration hole. This program commenced November 5, 2016, and was completed on December 20, 2016, and a total of 7 holes with a cumulative length of 14,432 feet were drilled. The preliminary exploration results received have been positive with the best results to date received from the northwest most hole. The mineralization to the west, northwest and at depth has been expanded with the drilling and remains open in these directions. More drilling is needed to prove up the extent of this mineralization.

Over 120,000 samples have been taken for total copper analysis from drilling at Gibraltar since 1965. About 95% of these samples were also assayed for molybdenum, 56% for acid soluble copper, 40% for multi-element ICP and 30% for gold. Essentially all rock drilled and recovered is sampled in 10 ft intervals. Unconsolidated overburden material, where it exists, is generally not recovered by core drilling and therefore not usually sampled.

From discovery in 1965 through mine start-up in 1971, and since mine re-start in 2004, assays on exploration drill samples have been performed by reputable, independent third party analytical laboratories. Mine laboratory personnel performed all exploration drill sample analyses from 1979 to 2003.

Well-documented sample preparation, security and analytical procedures used on the Gibraltar drill programs since 1999 have been carried out in an appropriate manner consistent with common industry practice. The results are supported by many years of mine production. A significant amount of due diligence and analytical QAQC for copper and molybdenum has been completed on the samples that were used in the current mineral resource/reserve estimate. The quality of the work performed on the digital database provides confidence that it is of good quality and acceptable for use in geological and resource modeling of the Gibraltar deposits.

Details of sample preparation, assay laboratories, security, and data verification used in the Gibraltar drill hole sampling and analytical programs is documented in the Gibraltar Technical Report.

Sulphide ore from the Gibraltar deposits has been processed on-site since 1972 and run of mine oxide ore has been leached since 1986. The current mineral reserves are contained within zones which have been significantly mined, with the exception of the Extension Zone. Metallurgical testing associated with the Extension Zone returned results consistent with the larger ore body.

The basis for predictions of copper concentrate flotation recovery is plant performance data from both of the existing concentrators based on sulphide and oxide content. Copper recovery averages 88% over the remaining operating period of the reserves.

Closed circuit cleaner locked cycle tests on Gibraltar bulk copper concentrate provide recovery values in the range of 90 to 93% at a final molybdenum grade greater than 50%. Applying the predicted molybdenum recovery from the locked cycle tests to the average bulk flotation circuit molybdenum recovery supports the molybdenum recovery of 50% used in economic calculations.

The basis of the predictions of copper cathode produced from heap leaching and subsequent solvent extraction is based upon historical leaching recovery curves. These curves take into account the annual recovery declination from the date of material placement.

The Gibraltar Mine mineral resources and reserves are based on the published reserves as of December 31, 2014, as documented in the Gibraltar Technical Report and reflects depletion due to mining in 2015 and 2016.

The reserve estimate uses long-term metal prices of US$2.75/lb for copper and US$11.00/lb for molybdenum and a foreign exchange of C$1=US$0.85.

Cautionary Note to Investors concerning estimates of Measured and Indicated Resources

The following section uses the terms “measured” and “indicated resources”. We advise investors that while those terms are recognized and required by Canadian regulations, the U.S. Securities and Exchange Commission does not recognize them. Investors are cautioned not to assume that any part or all mineral deposits in these categories that are not already classified as “reserves” will ever be converted into reserves.

The resource estimate uses long-term metal prices of US$3.50/lb for copper and US$11.00/lb for molybdenum and a foreign exchange rate of C$1=US$0.90.

The mineral reserves stated in Table 2 above are contained within the mineral resources indicated in Table 4 below:

Category	Tons (millions)	Cu (%)	Mo (%)
Measured	773	0.26	0.008
Indicated	258	0.24	0.007
Total	1,031	0.25	0.008

The mineral resource and reserve estimations were completed by Gibraltar Mine staff under the supervision of Scott Jones, P.Eng., Vice-President, Engineering, a Qualified Person under NI 43-101 and the author of the Gibraltar Technical Report. Mr. Jones has verified the methods used to determine grade and tonnage in the geological model, reviewed the long-range mine plan, and directed the updated economic evaluation.

The Gibraltar Mine is a typical open pit operation that utilizes drilling, blasting, cable shovel loading and large-scale truck hauling to excavate rock. The Gibraltar Mine is planned for excavation of sulphide mineralized material of sufficient grade that it can be economically mined, crushed, ground and processed to a saleable product by froth flotation.

Rock containing lower grade sulphide mineralization or oxide mineralization is also mined but is not immediately processed. The lower grade sulphide material is stockpiled for later processing in the concentrator. In addition, a portion of the low grade sulphide material and all of the oxide material can be leached with a highly diluted sulphuric acid, which is naturally assisted by bacterial action, and the resultant copper sulphate solution can be processed to cathode copper in the Gibraltar Mine’s SX/EW plant.

The strip ratio over the remaining 23 year operating period of the reserve will average 1.9 strip ratio refers to the ratio of the amount of overburden (or waste material) required to be mined in order to extract a unit of ore. For example, a 3:1 stripping ratio means that mining one tonne of ore will require mining three tonnes of waste rock. While the annual strip ratio generally decreases with time, the strip ratio will vary and be managed over the course of the mine life based on exchange rates, commodity prices, and grade distribution during annual and midrange mine planning process to optimize the economic performance of the operation.

The processing facilities at the Gibraltar Mine consist of two separate bulk sulphide concentrators, a dedicated molybdenum flotation plant, and a series of leach piles which feed a solvent extraction and electrowinning (“SX/EW”) facility.

Run of mine ore is fed to the two sulphide concentrators in parallel at a combined design rate of 85,000 t/day. These two bulk concentrators, while differing in size, follow the same process path. Ore is fed to primary crushing with the product reporting to a closed circuit SAG/Ball comminution stage. Ground ore is processed through a rougher flotation stage. Tailings from the rougher flotation stage are pumped to a storage facility, while the concentrate is reground and processed through two further cleaner flotation stages. Final bulk concentrate contains both copper and molybdenum values.

The bulk concentrate from both facilities is combined and processed through a single molybdenum flotation plant. The bulk concentrate is floated in a rougher stage which depresses the copper values and selectively recovers molybdenum. The underflow from this plant is the site’s final copper concentrate. This copper concentrate is dewatered and shipped in bulk to market. The rougher concentrate is reground and processed through two further cleaner flotation stages. Molybdenum final concentrate from this plant is dewatered and bagged, and subsequently shipped to market. The molybdenum flotation plant was restarted in September 2016 after being idled in July 2015 during a decline in molybdenum prices.

Oxide ore from the mine is delivered to oxide leach dumps. The SX/EW plant is designed to extract copper from the pregnant leach solutions (“PLS”) collected from the site’s leach dumps. Acidic solution is passed through the leach pile and extracts copper in the form of copper ions in this PLS. This copper laden solution is delivered to the SX/EW plant via collection ditches, ponds and pumping where required. The process takes PLS and selectively extracts the copper ions in solvent extraction mixer-settlers. The copper is transferred from this acid solution to an organic phase and finally to a clean electrolyte. The electrolyte is filtered and heated before being passed through the electrowinning cells where the copper is plated out on stainless steel cathodes. The resultant high quality cathode copper is bundled and sold. The barren solution leaving the plant, raffinate, is pumped back to leach additional copper from the leach piles.

Gibraltar’s copper concentrate has an approximately 28% copper content grade and no significant deleterious elements. Gibraltar copper cathode is nominally 99.9%+ pure copper.

The Canadian National Railway (“CN”) has rail service to facilitate the shipping of copper concentrates to Vancouver Wharves, owned and operated by Kinder Morgan in North Vancouver, British Columbia. The Company owns and operates the concentrate rail load-out facility on the CN rail line at Macalister, 26 kilometres from the mine site. Electricity is obtained from BC Hydro. Natural gas is provided by Fortis BC. The communities of Williams Lake and Quesnel are sufficiently close to the site to supply goods, services, and personnel to the Gibraltar Mine. The Gibraltar Mine had over 620 active personnel at the end of December 2016. Make-up fresh water for the mine site is obtained from a set of wells on the Gibraltar Mine property. Process facilities operate using reclaimed water from the existing tailings storage facility

Water currently stored in the Gibraltar Pit will be transferred to the completed Granite pit starting in early 2025. This will require the construction of a bulk pit dewatering system.

Relocation of the in-pit crusher feeding concentrator 1 will need to be completed by 2023 prior to starting phase 2 of the Connector Pit.

With the current design parameters and tailings deposition plan, the tailings facility footprint will accommodate tailings storage until at least 2033. It is anticipated that actual tailings deposition performance will enable deposition of all tailings generated in the reserve mine plan within the existing facility footprint.

All material regulatory authorizations and permits are in place to extract the reserves described in this report with the exception of:

Other permit considerations include approvals required for route changes to the access road, hydro transmission line, natural gas line, and water discharge pipeline in order to complete development of the Extension Pit which is scheduled to start in 2032. Approvals will be sought as required.

There have been no material environmental non-compliance incidents since the mine reopened in 2004.

As the majority of the mine’s facilities are in place and operating, the only capital requirements are for the relocation of the in-pit crusher/conveyor system and electrical substation, bulk pit dewatering, specific tailings and water discharge related activities, and sustaining capital to maintain the integrity of the mining and processing equipment.

The total anticipated site capital requirements over the next 23 years are summarized in Table 5.

Area	Total Capital (in millions)
Bulk Pit Dewatering	$15
Tailings and Water Reclaim/Discharge	$4
Crusher Relocation	$36
Pit Substation Relocation	$3
Road and Gas Line Relocation	$5
General Sustaining	$221
Total	$284

Average estimated unit site operating costs over the next 23 years are summarized in Table 6:

Operating Category	Life of Mine Cost
Mining cost/ton mined¹	$1.74
Milling cost/ton milled	$3.87
General and Administrative cost/ton milled	$0.91
Total operating cost/ton milled	$9.78

The basis for capital and operating cost estimates are documented in the Gibraltar Technical Report.

Gibraltar is pursuing initiatives to improve recovery, concentrator throughput, and mine cost and productivity. Continued improvement in any or all of these areas will have not only positive economic implications but could increase the size of the reserve pits under current commodity assumptions and/or impact the optimum cut-off grade.

Unless stated otherwise, the information of a technical or scientific nature related to the Florence Copper Project contained in this AIF is summarized or extracted from the technical report entitled “NI 43–101 Technical Report, Florence Copper Project, Florence, Pinal County, Arizona” dated February 28, 2017 (the “Florence Copper Technical Report”) prepared by Dan Johnson, P.E., RM-SME who is a Qualified Person as defined by NI 43-101 and filed on www.sedar.com under Taseko’s profile.

The Florence Copper Project (or “Florence Copper”) is an advanced-stage oxide copper project controlled 100 percent by Taseko Mines Limited. The project hosts a buried porphyry copper deposit that is amenable to in-situ copper recovery (“ISCR”) and solvent extraction-electrowinning (“SX/EW”) copper production.

Florence Copper is located in the Sonoran Desert of Pinal County in south-central Arizona at latitude 33° 02’ 49” North and longitude 111° 25’ 48” West within the limits of the Town of Florence. The Florence Copper site entrance is 14 miles by paved highway from Interstate 10 and can be accessed from the center of the Town of Florence via 4 miles of highway (AZ-79 and Hunt Highway). The Copper Basin Railway, a federally regulated shortline railroad, is located 100 feet north of Hunt Highway adjacent to the project site and provides rail access between the town of Winkelman and the Union Pacific Railroad at the Magma loading station near Interstate 10.

The Florence Copper property is 1,342 acres and consists of two contiguous parcels of land. Florence Copper owns surface and subsurface rites to 1,182 acres of patented land held in fee simple that includes the majority of the project area. The patented land is subject to annual property taxes and falls within the jurisdiction of the Town of Florence for zoning and land use. Florence Copper also holds Arizona State Mineral Lease 11-26500 that includes approximately 160 acres of surface and subsurface mineral rights on Arizona State Trust Lands, which is not subject to the jurisdiction of the Town of Florence for land use. The Arizona State Mineral Lease term is from December 2013 through to December 2033 and is renewable with Florence Copper having the preferred right to renew thereafter. The mineral lease requires annual rent to be paid to the State of Arizona and includes a royalty requirement on production from the mineral lease land. The Arizona State Mineral Lease is in good standing and the State Trust Lands overlie approximately 42 percent of the targeted copper resource.

There are three separate royalties applicable to Florence Copper. The land subject to Arizona State Mineral Lease 11-26500 is subject to a royalty payable to the State of Arizona based on a percentage (between 2% and 8% according to a “Copper Index Price”) of the gross value of minerals produced. A 3% “Net Returns” royalty on the entire property is payable to Conoco Inc. and a 2.5% “Net Profits Interest” royalty applicable to the patented land is payable to BHP Billiton.

Although there are some limited environmental liabilities on the project site relating to historical mining and exploration activities conducted by previous owners, these are managed by the company and do not pose a risk to access, title or the ability to perform work on the project.

The patented land portion of the project is currently the subject of a legal non-conforming use litigation which may affect the company’s ability to access the portion of the deposit on the patented land. Further legal details are included in the section of this AIF entitled “Legal and Permitting”.

The project has had four previous owners whose primary business is exploration and mining development including Continental Oil Company (“Conoco”), Magma Copper Company (“Magma”), BHP Copper Inc. (“BHP”) and Curis Resources Ltd. (“Curis”). BHP conveyed the land constituting the Florence Copper Project to Florence Copper Inc. on May 2000. In the years between 2002 and 2009 the ownership of the private property passed through a number of companies including Roadrunner Resorts LLC, WHM Merrill Ranch Investments LLC, The Peoples Bank, and Merrill Ranch Properties LLC. Ownership of Arizona State Mineral Lease 11-26500 remained with Florence Copper Inc. which was acquired by Felix-Hunt Highway LLC in 2008. Curis purchased the surface rights and all of the mineral rights to the 1,182 acre private land component of the Florence Copper Project in December 2009. In February 2010, Curis obtained assignment of Arizona State Mineral Lease 11-26500 completing the land holdings that form the Florence Copper site. Curis was acquired by Taseko in November 2014.

Conoco discovered the Florence Copper deposit in 1970 while executing an exploratory drilling program southwest of Poston Butte. From 1970 to 1977 Conoco completed approximately six hundred and twenty thousand feet of exploration drilling in 612 drill holes. In 1974, Conoco mined approximately fifty thousand tons of mineralized material from a single-level, underground mine designed to collect sample for metallurgical and geological testing. Metallurgical testing of the recovered material was performed using a small plant built on the property. The mine shafts are now capped at the ground surface and the mine is flooded.

Magma acquired the property from Conoco in July 1992 and initiated a Pre-Feasibility Study to verify the Conoco work and to determine the most effective technology for extracting copper from the deposit. The results from copper resource modeling, metallurgical testing, material property testing, and financial analysis supported the conclusion that the preferred method for development of the property was ISCR and SX/EW to produce cathode copper. Magma also completed approximately 150,000 feet of exploration drilling in 172 drill holes over the period from 1994 to 1996.

In January 1996, Broken Hill Proprietary Company Limited of Australia acquired Magma and created BHP. In 1998, BHP conducted a 90-day field optimization ISCR test to demonstrate hydraulic control, gather copper recovery and other technical data for a feasibility study. The outcome of the study confirmed to regulatory agencies that production wells could be efficiently installed into the mineralized zone, hydraulic control of the injected and process solutions could be maintained and documented, and that the ISCR method was a viable method for copper extraction at Florence Copper. BHP also completed approximately seventeen thousand feet of exploration drilling in 21 drill holes in 1997.

After completing the acquisition of Florence Copper in February 2010, Curis conducted approximately eight thousand feet of drilling in 6 drill holes to verify previous results, provide metallurgical samples, and information for further project development. Curis performed detailed data verification and generated a new resource model for the project as well as undertaking a metallurgical program focused on simulating in-situ conditions by using whole core box leach tests.

The Florence Copper Project hosts a porphyry copper deposit consisting of a large core of sulfide copper mineralization underlying a zone of oxide copper mineralization. The deposit formed when numerous dike swarms of Laramide granodiorite porphyry intruded Precambrian quartz monzonite near Poston Butte. Hydrothermal solutions associated with the intrusion altered the host rock depositing copper and iron sulfide minerals in the strongly faulted and fractured rocks.

Mid-Tertiary Basin and Range extensional faults subsequently elevated and isolated much of the Florence Copper deposit as a horst block and this block as well as the downthrown fault blocks were exposed to weathering and erosion. The centre of the deposit was eventually eroded to a gently undulating surface and the deposit was buried due to regional erosion processes to a depth of approximately 400 feet. During this period of erosion and deposition, a clay layer was deposited approximately 75 feet above the bedrock surface that impedes the mixing of groundwater between the near surface aquifer and the deeper aquifer hosting the mineralized zone.

Mineralization in the highly-fractured oxide zone consists primarily of chrysocolla with lesser “copper wad,” tenorite, cuprite, native copper, and trace azurite and brochantite. The majority of the copper occurs as chrysocolla in veins and fracture fillings, while the remainder occurs as copper-bearing clays in fracture fillings and former plagioclase sites. The average thickness of the oxidized zone is approximately 400 feet.

The main sulfide minerals in the deposit are chalcopyrite, pyrite and molybdenite with minor chalcocite and covellite. The supergene chalcocite blanket is very thin and irregular and in most instances the transition from the oxide zone to the sulfide zone is quite abrupt.

Substantial exploration work has been undertaken on the Florence Copper site by previous owners including drilling (exploration, assessment, condemnation, geotechnical and environmental), underground mine development, geophysical surveys and mineralogy studies.

Over the period since Taseko acquired the Florence Copper Project, the Company has not conducted any exploration work on the property, its activities concentrating on permitting and metallurgical testing, and engineering.

Drilling on the Florence Copper site has been undertaken by means of core drilling, RC rotary drilling and conventional rotary drilling. Conoco developed a detailed geologic core logging protocol in the early to mid-1970s and subsequent geologists have continued to use this method, with slight modifications, to maintain continuity of the geologic data produced.

Since 2009, work on the property has been focused on the site’s potential copper production through ISCR which has included the drilling of 6 holes to obtain samples for metallurgical testing and engineering studies to support planning for project development.

Company	# of Drill Holes	Core Length (metres)
Curis Resources (2011)	6	7,752
BHP Copper (1997)	21	16,638
Magma Copper Company (1994-1996)	172	146,891
Conoco (1970-1977)	612	620,483
Other	6	3,716
Total	817	795,480

Sampling protocols were developed by previous owners to ensure consistency and mitigate bias. Sampling consisted of core samples and cuttings from drilling, as well as bulk samples obtained from the underground workings. Core samples as well as conventional rotary and reverse circulation drill cuttings were all assayed, although assays for conventional rotary cuttings are considered unreliable and have not been used in the project data set. Core samples provide the most representative, unbiased samples of the mineralized materials encountered in the borehole.

Assays of drill samples were conducted by various laboratories under the supervision of Arizona-registered assayers and laboratory managers. The “San Manuel Method” was consistently used by Magma, BHP and outside laboratories contracted for the analysis of percent acid-soluble copper content in the Florence drill and metallurgical test samples.

Data verification has been performed by each company conducting exploration and development at the Florence Copper site. Analytical results from the 2011 Curis metallurgical and confirmation drilling program indicated copper concentrations similar to those collected from prior drilling programs performed in the same areas. Historical drill core and pulps are stored at the Florence Copper site in a secure facility.

A review, conducted by SRK Consulting, concluded that the sampling, analysis and data verification conducted on the Florence Copper site followed industry standard practice and that the resultant drill hole database, including assays and other information, is of high quality and has been sufficiently verified.

The Florence Copper property has a long history of metallurgical testing which establishes the amenability of the site oxide copper mineralization to leaching. Historic test work has included laboratory scale column testing and vat leaching as well as pilot scale vat and agitation leaching. These tests have been conducted on material sourced from drill core as well as a bulk sample from the test underground mining.

Recent metallurgical test work has focused on test methods specific to simulating ISCR performance. This program began in 2011 with box leach tests where whole drill core was leached at near atmospheric pressure to simulate leaching of undisturbed ore. In 2013 development of a pressurized test apparatus led to tests on whole drill core to simulate the hydrostatic pressure in the ore body during leaching and rinsing. This pressurized test apparatus has been refined to more accurately simulate ISCR conditions as the test work has proceeded and a test linking seven pressurized cells in series was completed in 2016. This series leach test passed solutions through approximately 15 feet of whole core with a solution transit time of about 13 days, representing approximately the mid-point of scale-up between a single pressurized test with a solution transit time of less than two days and the full scale well field with an estimated 30 days transit time. The development of the ISCR leach test methodologies culminating in the series leach test has allowed the laboratory to produce mature leach solutions with compositions that closely correspond to those predicted for the full scale operation. All of the ISCR leach testing was conducted in closed circuit and used solvent extraction to recover the leached copper into a proxy electrolyte solution.

The leaching model for ISCR at Florence is based on data from the box leach tests, individual pressurized tests and the series testing. Laboratory data used for modelling is subjected to a validation process based on established industry practice in the copper leaching field. The leach model is then combined with a model of sweep efficiency, which adjusts for the amount of mineralized material that would be contacted by solutions over time in the ISCR well field, and a recovery factor to account for the proportion of copper leached which is plated as cathode copper. Recovery to cathode copper is predicted to be 70% over a four year leach cycle for Florence Copper.

The Florence Copper mineral reserves, as defined by the Florence Copper Technical Report, are based on ISCR from the oxide zone material combined with SX/EW to produce cathode copper. The reserves utilize a copper price of US$2.50 and the reserve estimate is presented in Table 8 below. The Probable reserve estimate includes the resources categorized as Measured and Indicated for oxide material within the resource boundary. The Probable reserve estimate does not include the inferred resources within the resource boundary.

	Tons (in millions)	Grade	Contained Cu (in millions lbs)
Probable	345	0.36	2,473
Note: Contained metal values do not account for metallurgical recoveries. The tonnage factor is 12.5 ft³/ton.

Cautionary Note to Investors concerning estimates of Measured and Indicated Resources

The Florence Copper mineral resource is summarized in the Table 9 and includes the mineral reserves included in Table 8 above. Only oxide mineralization in bedrock is included in the estimates as sulfide mineralization is not considered recoverable by ISCR methods and is consequently not included in either the current mineral resource or reserve estimates.

All Oxide in Bedrock (0.05 %TCu cutoff)
Class	Tons (in millions)	Grade	Cu (in millions lbs)
Measured	296	0.35	2,094
Indicated	134	0.28	745
M+I	429	0.33	2,839
Inferred	63	0.24	295
Note: All oxide includes the entire copper oxide zone and iron-oxide leached cap zone including the top 40-foot of bedrock (bedrock exclusion zone). Contained metal values do not account for metallurgical recoveries. The tonnage factor is 12.5 ft³/ton.

The mining method proposed for Florence Copper is ISCR which is an extraction method used for selected mineral deposit conditions as an alternative to open pit or underground mine methods. The Florence Copper deposit is amenable to the ISCR method due to the high degree of natural fracturing in the oxide zone, connectivity of the fractures, acid soluble copper mineralization that occurs on the faces of the fractures, and host rocks as well as deposit hydrologic conditions which are favorable for leaching operations.

The ISCR process involves drilling wells into the mineralized material and circulating a dilute low pH lixiviant solution (consisting of 99% water) through the ore between injection and recovery wells. The lixiviant solution dissolves the copper minerals and the resulting copper rich solution is processed in a conventional SX/EW plant where the copper is removed from the solution and plated as cathode copper.

The ISCR method is highly environmentally efficient, does not require the large scale movement of waste rock or ore and will have minimal impact on the site topography. Using ISCR will result in the project consuming less energy, less water and producing less carbon dioxide emissions and waste per pound of copper produced than a conventional mining operation. The project well field design includes a surrounding network of perimeter wells and monitoring wells to ensure that the process solutions remain in the mineralized zone and, when leaching in an area is completed, the process solutions will be rinsed from the block to restore the ground water quality.

Copper recovery at Florence Copper will utilize conventional SX/EW technology to produce cathode copper from the copper-bearing leach solutions pumped from the ISCR well field. The planned commercial SX/EW plant is designed to handle a flow of 11,000 gpm with a PLS grade of 2 grams per litre.

The planned processing plant and associated infrastructure will be located on Florence Copper private land to the east of the State Land parcel. The process fluids are piped to and from the process plant in lined trenches.

The Florence Copper area has excellent local infrastructure and vendor resources to support exploration, development, and mining. Service companies for the metals/non-metals, coal, oil and gas industries are located in Phoenix and Tucson as well as, at a greater distance, in Albuquerque, New Mexico and Denver, Colorado. Skilled manpower resources are readily available locally due to the area’s long history of copper exploration and mining.

The project site has an administration building, warehouse building, equipment laydown yard and core storage facility. The project site is serviced from existing water wells for its’ potable water needs as well as for future process requirements. The site is also presently serviced with electrical power, trash pick-up, a septic system for sanitary wastes and full communication services including landline telephone, cellular telephone and internet services.

Power for commercial development of the project is available from an Arizona Public Service high-voltage transmission line at the northwest corner of the property. Natural gas is available in the area from Southwest Gas approximately one mile east of the site.

The various permits required to authorize the Florence Copper Phase 1 Production Test Facility (“PTF”) have been issued by the regulators and are in the process of being finalized. The status of permitting activities is provided below.

The Temporary Aquifer Protection Permit (“APP”) for the PTF was issued in August 2016 by the Arizona Department of Environmental Quality (“ADEQ”) and was subject to an appeal. The Water Quality Appeals Board conducted a hearing on three remaining issues under appeal and dismissed the appeal, upholding the permit.

In February 2016, the United States Environmental Protection Agency (the “EPA”) issued the final Memorandum of Agreement in accordance to the Section 106 National Historic Preservation Act for the archeological work associated with the construction of the PTF. In December 2016, the Company received the final Underground Injection Control (“UIC”) Permit for the PTF from the EPA. This permit is now going through an appeal process.

After the UIC permit is finalized the Company will have all of the permits required for construction and operation of the PTF. The timing to finalize this permit is somewhat uncertain but the Company anticipates completion in mid-2017.

The estimated pre-production capital cost for the Florence Copper commercial production facility is US$204 million. A summary of the major components of the capital cost estimate is presented in Table 10.

Item	Capital Cost (millions $US)
Pre-Production ISCR Well Field	$42
SX/EW Plant	$49
Utilities, Infrastructure and Ancillaries	$14
Indirect Costs	$61
Owner’s Costs	$21
Total Construction Capital Costs	$188
Pre-Production Operating Costs	$16
Total Pre-Production and Capital Costs	$204

Sustaining capital expenditures during the production period were estimated to be US$713 million. This capital will be expended over a 22-year period and consists of US$624 million for well field development and US$89 million for a water treatment plant and construction of process water ponds.

Details of the basis for capital cost estimates can be found in the Florence Copper Technical Report.

The estimated average operating costs for Florence Copper over the life of mine is US$0.90 per pound of copper and the estimated total production cost is US$1.10 per pound of copper produced inclusive of royalties. Details of the estimated operating costs are presented in Table 11.

Item	Operating Cost ($US per lb copper)

General and Administration	$0.19
Reclamation	$0.04
Off Property Costs	$0.02
Total Operational Costs	$0.90
Royalties	$0.21
Total Production Costs	$1.10

The details of the basis for the project operating cost estimate can be found in the Florence Copper Technical Report.

The main assumptions and inputs to the base case economic analysis of the Florence Copper Project are:

The base case economic analysis of the Florence Copper Project yields the following key economic indicators:

Development of the site is planned to occur in two phases. The first phase is construction and operation of the PTF which will demonstrate the application of ISCR to the Florence Copper Project. The second phase is the construction and operation of the commercial ISCR facility with a production capacity of 85 million pounds of cathode copper per year and an expected average annual production of 81 million pounds of copper over 21 years. The Company is currently in the final stages of permitting for the PTF phase.

On September 28, 2012, the ADEQ issued Florence Copper an APP for the development of a PTF, which involves the construction, operation and closure of a 24-well ISCR operation on the State Land portion of the Company’s project site. Following the completion of the required public comment and response period, on July 3, 2013 ADEQ issued to Florence Copper an appealable APP. On August 2, 2013 a single appeal to the Water Quality Appeals Board (“WQAB”) was filed by the Town of Florence and others. The WQAB referred the matter to the Office of Administrative Hearings (“OAH”) to conduct an administrative hearing, which took place from March 18, 2014 through May 7, 2014. The Administrative Law Judge (“ALJ”) issued a recommendation to the WQAB on September 29, 2014. On November 14, 2014, the WQAB issued its Final Order, which adopted most of the ALJ’s recommendations and remanded the APP to ADEQ to amend pursuant to the agency’s Significant Amendment process. On April 1, 2015, Florence Copper submitted to ADEQ an application to amend its APP in accordance with the WQAB’s ruling. ADEQ issued a final Significant Amendment to the APP on August 3, 2016, following the completion of the required public comment and response period. The Town of Florence and two nearby property developers filed an appeal of the Significant Amendment with the WQAB on September 1, 2016. The WQAB conducted a hearing on three remaining issues under appeal and dismissed the appeal, upholding the permit.

On March 4, 2013, the Florence Town Council authorized the town staff to initiate an eminent domain action against Florence Copper’s patented mining land held in fee simple. The action did not include the 159.5 acre State Trust Land parcel on which Florence Copper can operate for nine years, including the Phase 1 PTF and the initial years of commercial operations. On October 14, 2013, the Town of Florence filed suit in Pinal County Superior Court seeking a declaration that (a) Florence Copper does not have vested contractual rights or common law rights to conduct in-situ copper recovery mining on its private property, and (b) if such rights exist, the Town seeks to expropriate a legal non-conforming use within its Town boundaries through eminent domain. Florence Copper filed a motion to change the case venue and a motion to dismiss the eminent domain portion of the complaint. The motion was granted and the case was moved to the Complex Litigation Bench in Maricopa County Superior Court. On July 2, 2015, Florence Copper’s motion to dismiss the eminent domain claim was also granted. The remaining issue now pending in Maricopa County Superior Court is whether a legal non-conforming use (“LNCU”) right to mine continues to exist on Florence Copper’s privately owned land. The Town filed a motion for summary judgment on the LNCU issue on November 10, 2015, however, Florence Copper requested, and the court agreed, that significant discovery must be undertaken before a ruling on the motion may be made. Following document production and witness depositions, Florence Copper filed a cross-motion for summary judgment on July 29, 2016. Both motions for summary judgment have been fully briefed and rulings are expected from the superior court judge in early March 2017.

On December 20, 2016, the EPA issued the final Underground Injection Control Permit to Florence Copper. This permit regulates the operation of Class III underground injection wells at the PTF. Three petitions for review have been filed with the Environmental Appeals Board (“EAB”) of the EPA. These petitions were filed by the Town of Florence and Southwest Value Partners, the Gila River Indian Community, and John Anderson, a Town Councilman representing himself. Responsive briefs from EPA and Florence Copper are due to the EAB on April 7, 2017. The EAB will then determine whether to grant full appellate briefing of one or more of the issues raised in the petitions or dismiss some or all of them. This review process is expected to be completed in 2017.

Unless stated otherwise, information of a technical or scientific nature related to the Aley Project contained in this AIF (including documents incorporated by reference herein) is summarized or extracted from a technical report entitled “Technical Report on Mineral Reserves at the Aley Project” dated October 30, 2014, (the “Aley Technical Report”) prepared by Scott Jones, P.Eng, Keith Merriam, P.Eng, Greg Yelland, P.Eng, Robert Rotzinger, P.Eng., and Ronald G. Simpson, P.Geo., each of whom is a Qualified Person as defined by NI 43-101 and filed on Taseko’s profile on SEDAR at www.sedar.com.

Niobium is a metal used in high strength low alloy steels which are required to manufacture automobiles, bridges, pipes, jet turbines and other high technology applications. Ninety percent of niobium enters the market as ferroniobium (FeNb); 15% of all steel produced worldwide contains FeNb. The increase in demand for FeNb has resulted largely from the overall growth in the global steel market. Demand for ferroniobium has grown at approximately 5-7% per annum in recent years and Taseko anticipates that growth to continue over the next 10 years. Currently, 90% of the world’s niobium is supplied by three mines: CBMM (Companhia Brasileira de Metalurgia e Mineração) and CMOC (China Molybdenum Co., Ltd.) mines in Brazil, and the Niobec mine operated by Magris Resources in Quebec, Canada.

The property is located in the Omineca Mining Division in British Columbia, Canada, centred at latitude 56°27’N and longitude 123°13’W, approximately 140 kms north northwest of the Municipality of Mackenzie. Logging roads from Mackenzie provide access to the Ospika Logging Camp on the east side of Williston Lake. The property is located about 30 kms from the Ospika Camp and is currently accessed via helicopter.

The Aley property consists of one mineral lease valid until at least December 2045 as long as annual renewal fees are paid, and one hundred and eleven mineral claims covering the mineral rights for approximately 470 square kms. Six claims are in good standing until December 2024 while the balance are in good standing until at least October 2025. It is intended that the lease and claims will be renewed prior to their renewal fees being due (in the case of the lease) and prior to their expiry in the case of the claims.

There are no title encumbrances, surface rights issues or legal access obligations that must be met in order for Aley Corporation to retain this property. The Aley Property is not subject to any royalty terms, back-in rights, payments or any other agreements or encumbrances.

As this is a green-field project, there are no existing environmental liabilities on the property and there has been no development at the site. When additional site work is required, permit applications will be made. The Company does not hold any surface rights.

Cominco Ltd. (“Cominco”) acquired the property in 1980 after following up on base metals soil anomalies in the northern part of the property. Samples collected in the Aley area showed evidence of carbonatite including niobium mineralization. Cominco staked a series of claims from 1982 through 1986.

Cominco field work from 1983 through 1986 included access trail construction, ground magnetic and scintillometer surveys, geologic mapping, soil and rock chip sampling and drilling of 19 core holes (3,046 metres). Preliminary metallurgical work followed in 1983-85 using material from a 5 ton bulk sample.

Following the acquisition of control of the mineral claims by Aley Corporation in 2004, exploration efforts concentrated on trench sampling for metallurgical material and the confirmation of previous geology and drill hole collar locations.

In 2006, metallurgical test work was conducted by on surface samples blasted from the Saddle and Central Zone trenches for metallurgical work.

In June 2007, Taseko acquired 100% of the Aley niobium project from Aley Corporation for total cash consideration of $1.5 million and 894,730 common shares then valued at $2.9 million. Taseko purchased the residual net smelter royalty for total cash consideration of $0.3 million and the issuance of units having a value at the time of $0.8 million (consisting of 240,000 common shares and 120,000 warrants).

From 2007 to 2011, Taseko completed three programs of helicopter supported exploration drilling comprising a total of 22,922 metres in 104 holes.

Drilling results through 2010 established an inferred mineral resource of 159 million tonnes grading 0.43% Nb₂O₅using a cut-off grade of 0.20% Nb₂O₅.

Drilling results through 2011 established a measured and indicated resource of 286 million tonnes grading 0.37% Nb₂O₅ using a cut-off grade of 0.20% Nb₂O₅.

From 2011 to 2014, Taseko focused on metallurgical testing of the ore and developing a viable process for producing FeNb to support the pre-feasibility level design work completed in 2014. Environmental baseline data collection was also carried out during this period.

Since 2014, Taseko has maintained key environmental baseline data collection. In late 2015, metallurgical process optimization work was initiated and is ongoing.

The Aley region lies within the Western Foreland belt of the Rocky Mountains. It is characterized by Early to Middle Paleozoic deep water carbonates and shales. The Aley Creek area lies near the eastern limit of Paleozoic volcanism and coarse clastic sedimentation in the Foreland Belt.

The Aley Carbonatite complex intrudes Cambrian to Ordovician sedimentary rocks of the Kechika (limestone), Skoki (dolomite to volcaniclastics) and Road River Group formations (clastic sedimentary rocks). The intrusion is ovoid in plan with a diameter of approximately 2 kms and surrounded by a fenite aureole up to 500 metres. The complex is predominantly composed of dolomite carbonatite (CD) with minor calcite carbonatite (CC). Texturally, relationships suggest CD to be metasomatic in origin while CC is interpreted to be primary.

Niobium (Nb) bearing minerals at Aley are pyrochlore, fersmite and columbite, the latter two being alteration products of pyrochlore. Alteration at Aley has followed a general sequence: pyrochlore has altered to fersmite then fersmite has altered to columbite.

The only non-drilling exploration work conducted by Taseko since acquiring the property is geologic mapping undertaken in 2009 and 2010 and geochemical mineralogical and petrographic characterization in 2010. This information was used to define targets in the 2010 and 2011 drill programs.

In 1985 and 1986 Cominco drilled twenty diamond drill holes totaling 3,062 metres in the Central and Saddle Zones.

Taseko completed an initial exploration program on the Aley deposit in 2007 that included 11 diamond drill holes to check the results of the 1985-86 drilling program and to plan for subsequent exploration work. No work was done on the Aley project in 2008 or 2009.

Taseko completed an exploration program in the summer of 2010, comprising geological mapping and 4,460 metres of diamond drilling in 23 holes in the Central Zone. These holes intersected excellent grade niobium mineralization across an area measuring over 900 metres east-west and 350 metres north-south. Mineralized drill intercepts ranged up to over 200 metres in length. Niobium mineralization intersected was highly continuous and close to surface. The extensive body of niobium mineralization indicated by the 2010 drilling was open to expansion in at least three directions and to depth.

In 2011, 17,094 metres of drilling were completed in 70 holes. The objective of the drill program was the delineation of the continuity and extent of Nb mineralization in the Central Zone with infill drilling. The program also sought to establish a better understanding of the deposit geometry and the continuity and extent of Nb mineralization.

Condemnation and geotechnical drilling totalling 2,493 metres was completed in 2012. In addition 10 kms of exploration access road right of way was cleared and 5 kms of road was established.

The sample database for the Aley project contains results from 104 core holes drilled between 1985 and the end of 2011. The Central Zone has been tested by 98 holes all of which are entirely within the carbonatite complex. All of the assays on drill samples have been performed by reputable, independent third party analytical laboratories.

Taseko implemented a QAQC program consistent with common industry practice after taking over the project in 2007. This program was in addition to the QAQC procedures used internally by the analytical laboratories. The results of this program indicate that analytical results are of high quality and suitable for use in detailed modeling and resource evaluation studies.

Details of sample preparation, assay laboratories, security, and data verification used in the drill hole sampling and analytical programs is documented in the Aley Technical Report.

The metallurgical testing that was used as the basis for design was conducted at SGS Laboratory in Vancouver, and at XPS in Sudbury from 2011 to 2014. The test program included: mineralogical work, liberation analysis, comminution test work, gravity work, magnetic separation, batch and locked cycle flotation programs and leach test work. The niobium concentrate produced from the work at SGS was sent to XPS for conversion test work.

The final flow sheet developed from the test work includes comminution, magnetic separation, flotation, leaching and final conversion.

The overall results from the series of tests conducted at the labs show that a process plant recovery of 71% was achieved in repeatable and stable locked cycle tests and a leach recovery average of 95% was achieved over all leach tests. The overall ferroniobium grade achieved was 63% Nb at a recovery to ferroniobium alloy of 65%.

The Company and its consultants carried out progressive engineering, metallurgical and environmental studies over the period 2011 to 2014, including completion of a pre-feasibility level study of the project in 2014.

The resulting mineral reserves using long-term metal prices of US$45.00/kg for niobium and an exchange rate of US$0.90/CDN$ 1.00 are shown in Table 12.

Cautionary Note to Investors concerning estimates of Measured and Indicated Resources

This section uses the terms “measured” and “indicated resources”. We advise investors that while those terms are recognized and required by Canadian regulations, the U.S. Securities and Exchange Commission does not recognize them. Investors are cautioned not to assume that any part or all mineral deposits in these categories that are not already classified as “reserves” will ever be converted into reserves.

The Resource Estimate is documented in the technical report titled “Technical Report Aley Carbonatite Niobium Project Omineca Mining District British Columbia, Canada” by Ronald G. Simpson, P. Geo., dated March 29, 2012, filed on www.sedar.com. That information remains current as there have been no additional relevant exploration results since that time within the resource area. The mineral resource for the Aley Deposit is summarized in Table 13 at a cut-off grade of 0.20% Nb₂O₅.

Category	Tonnes (millions)	Nb₂O₅(%)
Measured Indicated	113 173	0.41 0.35
Total Measured and Indicated	286	0.37
Inferred	144	0.32

The mineral resources shown in Table 13 include the mineral reserves shown in Table 12.

The mining method planned is a conventional open pit with equipment sized and fleet requirements determined to meet the required production rate.

The designed pit is subdivided into 2 phases, the first phase mining down the east ridge, the second phase mining the west and north ridges and down to the bottom of the pit. Using the 2 pit phases, a 24 year production schedule has been developed. For the final 4 years of the mill production under this plan, mining will have been completed from the pit and all mill feed will be from the stockpile.

The mine plan and production schedule were developed for a 10,000 tonnes per day mill feed operation and results in a life of mine strip waste:ore ratio of 0.5 to 1.

The processing plant has been designed with a nominal capacity of 10,000 tonnes per day. The plant consists of a three stage comminution circuit that consists of a SAG mill, a ball mill, and a fine grinding mill with the appropriate size classification circuits. Final comminution product is fed to the concentration plant, details of which are proprietary and confidential. An upgraded concentrate from the concentrator is fed to a leach facility for further processing, while waste streams produced in the concentrator are recombined and pumped to a tailings storage management facility. Leached concentrate residue is then processed through a calciner and proceeds to ferroniobium conversion. Converter waste is stored in a secure containment facility and final product ferroniobium is delivered to market.

Expected life-of-mine overall niobium metallurgical recovery is 63% with annual production averaging approximately 14 million kilograms of FeNb which is equivalent to approximately nine million kilograms of contained niobium over the 24 year mine life.

The ferroniobium will be hauled with highway trucks to a transfer station in Mackenzie for rail or truck transport to various points of sale, but primarily through the Port of Vancouver for shipment to smelters/refineries around the world.

Power is proposed to be supplied via a new 150 km long, 138 kV transmission line from the BC Hydro Morfee substation in the community of Mackenzie. Infrastructure would also include the upgrade of sections of the existing road to the site, an on-site camp, equipment maintenance shop, administration office, concentrator and converter facilities, warehouse, and explosives facilities.

The project would employ up to 325 permanent hourly and staff personnel. In addition, contractor personnel would be employed in areas including catering, and goods and personnel transportation.

On September 19, 2014, the British Columbia Environmental Assessment Office (“EAO”) issued a Section 10 Order under the British Columbia Environmental Assessment Act, initiating the provincial environmental assessment process for the Project.

On November 24, 2014, the Canadian Environmental Assessment Agency (“CEAA”) determined that a federal environmental assessment was required, issued a Notice of Commencement, and approved British Columbia’s request for Substitution under the Canadian Environmental Assessment Act, 2012. As a result the province will conduct the assessment and Aboriginal consultation on behalf of the Federal government.

On December 31, 2014, British Columbia issued a Section 11 Order under the Environmental Assessment Act describing the scope of the Aley project subject to the environmental assessment, identifying the Aboriginal Groups requiring consultation, and directing Taseko to draft Application Information Requirements (“AIR”) for the environmental assessment application.

A summary of the estimated pre-production capital costs estimated for the project is $870 million and is summarized in Table 14.

Area	Capital Cost (in millions)⁽¹⁾
Mining Equipment	$25
Capitalized Pre-Production Costs	$38
Process Plant - Concentrate	$166
Process Plant - FeNb Converter	$97
Sand Storage & Water Reclaim	$50
Ancillary Facilities	$43
On-Site Infrastructure	$62
Off-Site Infrastructure	$86
Subtotal Direct Costs	$569
Indirect Costs	$145
Owner’s Costs	$46
Contingency	$110
Subtotal for Indirect Costs	$301
Total	$870

All costs shown are in Q3 2014 Canadian dollars. No allowances have been made for escalation, interest and financing, taxes or working capital in the capital cost estimate.

Operating Category	Operating Cost ($/tonne)
Mining	$4.63
Processing	$44.90
General and administrative	$6.05
Off-site costs	$2.62
Total	$58.20

The basis for capital and operating cost estimates are documented in the Aley Technical Report.

A list of the main assumptions and inputs to the economic analysis of the Aley project are listed below:

The following pre-tax economic indicators are derived from the base case life of mine cash flow:

The Company is currently preparing the draft Application Information Requirements (“AIR”) for the Environmental Assessment. The EAO has established a Working Group, comprising of representatives of CEAA, government agencies, First Nations, and local governments. This group will provide input on aspects of the environmental assessment including the AIR.

Environmental monitoring of surface and groundwater baseline conditions and geochemical characterization of ore, waste rock, and tailings in support of the Environmental Impact Statement is ongoing. Although the majority of the ongoing work on the Aley Project is environmental assessment related, some additional metallurgical process optimization work commenced in the fourth quarter of 2015. This work consists of evaluating alternatives for both the hydrometallurgical and pyrometallurgical portions of the project flow sheet. An internal review of the project metallurgical testing and flow sheet development identified these process steps as having significant potential to reduce both the project pre-production capital cost and the operating costs.

Unless stated otherwise, information of a technical or scientific nature related to the Prosperity project contained in this AIF is summarized or extracted from a technical report entitled “Technical Report on the 344 Million Tonne Increase in Mineral Reserves at the Prosperity Gold – Copper Project” dated December 17, 2009, (the “Prosperity Technical Report”) prepared by Scott Jones, P. Eng. and filed on Taseko’s profile on SEDAR at www.sedar.com. Mr. Jones is employed by the Company as Vice-President, Engineering and is a Qualified Person as defined by NI 43-101. Readers are cautioned that the Prosperity Technical Report is now some seven years old and accordingly caution needs to be advised when assessing its conclusions in light of current operating and capital costs, appropriate technologies, metals price outlooks, and like matters.

The Prosperity project is located at latitude 51° 28’ N and longitude 123° 37’ W in the Clinton Mining Division, approximately 125 kms southwest of the City of Williams Lake, British Columbia.

Access from Williams Lake is via Highway 20 to Lee’s Corner, then via an all-weather main logging haulage road to the site, a total road distance of 192 kilometres.

The Prosperity property consists of one mineral lease which is valid until at least June 2035 as long as renewal fees, which are due on an annual basis, are paid, and 85 mineral claims covering the mineral rights for approximately 190 square kms. Six claims are in good standing until at least June 2017, while the remainder are in good standing until at least December 2018. It is intended that all leases and claims will be renewed prior to their renewal fees being due (in the case of the lease) and prior to their expiry in the case of the claims.

The claims are 100% owned by Taseko and are not subject to any royalties or carried interests.

The Prosperity deposit was originally discovered by prospectors in the early 1930’s. Phelps Dodge Corporation conducted a small exploration program in the early 1960’s and subsequently allowed the claims to lapse.

In 1969, Taseko acquired the property and drilled 18 holes totalling approximately 2,300 metres immediately to the south of the area previously explored, discovering significant tonnage grading 0.25% to 0.30% copper.

From 1970 to 1974, under option agreements with Nittetsu Mining Company and Quintana Minerals Corporation, approximately 5,000 metres of drilling was completed in 29 holes. Bethlehem Copper Corp. (“Bethlehem”) optioned the project in 1979 and by 1981 had completed approximately 14,000 metres of drilling in 73 holes. Following the corporate merger of Bethlehem and Cominco Ltd. (“Cominco”) Cominco acquired the Bethlehem option agreement on the property. From 1982 to 1989 Cominco work programs included geophysical and soil geochemical surveys, an additional 5,300 metres of drilling in 48 holes, and a limited metallurgical test work program. In 1990, Cominco Ltd. reported a drill–indicated mineral resource of 208 million tonnes at an average grade of 0.23% Cu and 0.41 gpt Au to 360 metres below surface.

After a period of disagreement with Cominco regarding compliance with the option agreement, which included legal proceedings, in 1993 Taseko acquired 100% of the project free of any royalties or third party interests through settlement agreements.

Following drilling in 1991 and 1992, Taseko reported mineralized material (unclassified mineral resource) of 976 million tonnes at an average grade of 0.23% Cu and 0.48 gpt Au.

Comprehensive metallurgical tests were completed in 1993 and a pre-feasibility report was completed in 1994.

Following a significant drill program in the latter half of the 1990’s, in 1998 Taseko reported estimated measured and indicated mineral resources of 1.0 billion tonnes at 0.41 gpt Au and 0.24% Cu and an inferred resource of 0.2 billion tonnes grading 0.25 gpt Au and 0.21% Cu at a 0.14% copper cut-off.

Work on the project was deferred from 2000 to 2005 first due to low metal prices and then later as the Company turned its attention to re-starting the Gibraltar Mine. In November 2005, work was reactivated on the project. A pre-feasibility level study was completed in the first quarter of fiscal 2007 followed by a full feasibility study in the fall of that year. In 2008 Taseko worked with a number of consultants to investigate value engineering opportunities, energy efficiency, and operating ease in various areas of the concentrator and support infrastructure. The outcome of this work, in combination with a significantly different outlook for copper and gold prices in 2009 resulted in the current reserve.

In late 2009 and 2010, additional metallurgical testing and geotechnical investigations were undertaken in support of detailed engineering.

In 2010, Taseko worked with various consultants to advance project engineering to the detailed phase and to advance various permit applications. Taseko temporarily suspended work on detailed engineering and permitting in November 2010 following the federal cabinet’s decision on the environmental assessment.

In early 2011, Taseko began design revisions to the project to address the concerns identified during the federal review process.

In early 2012, Taseko completed a geotechnical field investigation to support the design and environmental assessment of the relocated tailings facility proposed as part of a New Prosperity Design.

There has been no production from the property and there is no material infrastructure on the project.

The project is located within the western-most portion of the Intermontane Belt at the boundary between the Intermontane and Coast morphologic belts. The surrounding area is underlain by poorly exposed, Late Paleozoic to Cretaceous litho tectonic assemblages which have been intruded by plutons of Mid-Cretaceous to Early Tertiary age. The main Coast Plutonic Complex is 50 kilometres southwest of the New Prosperity project area.

The Yalakom Fault is the major fault in the region and lies to the southwest of the deposit on the New Prosperity project. Estimates of Eocene dextral strike-slip offsets for the Yalakom Fault have been postulated variously as ranging from 80 to 190 kms, 125 to 175 kms or 115 kms. It may have imparted some related structural controls that are important to the localization of mineralization at the deposit.

The project hosts a large porphyry gold-copper deposit. The deposit is predominantly hosted in Cretaceous andesitic volcaniclastic and volcanic rocks. In the western portion of the deposit, the host rocks have been intruded by the multi-phase, steeply dipping Fish Creek Stock. The stock is surrounded by an east-west trending, south dipping swarm of subparallel quartz-feldspar porphyritic dykes. The stock and dykes comprise the Late Cretaceous Fish Lake Intrusive Complex that is spatially and genetically related to the deposit. Post mineralization porphyritic diorite occurs as narrow dykes that cross-cut all host rocks. The central portion of the deposit is cut by two major faults, striking north-south and dipping steeply to the west.

Pyrite and chalcopyrite are the principal sulphide minerals in the deposit. They are uniformly distributed in disseminations, fracture fillings, veins and veinlets and may be accompanied by bornite and lesser molybdenite and tetrahedrite-tenantite. Native gold occurs as inclusions in and along microfractures with copper-bearing minerals and pyrite.

There has been no material non-drilling exploration conducted on the property since the early 1990’s. Exploration programs prior to this time included extensive IP and magnetic geophysical and soil geochemical surveys which contributed to the definition of the mineralization.

Until 1991, exploration programs on the property included 176 percussion and diamond drill holes totalling approximately 27,100 metres. This work helped define the project mineralization to a depth of 200 metres, and outlined a gold-copper mineralized zone approximately 850 metres in diameter.

Diamond drilling from 1991 through 1997 totalled approximately 85,000 metres in 267 holes, expanding the deposit to 1400 metres east-west, 600 metres north-south and to 850 metres below surface, increasing the density of drilling in the deposit, and adding to the geotechnical and geochemical characterization of the deposit.

Six core holes totaling 1,762 metres were drilled in 2007 for metallurgical purposes. The purpose of this program was to provide sufficient material representative of the various alteration zones anticipated to be encountered in the first six years of production.

Over 65,000 samples have been taken for analysis from drilling since 1969. All of the assays on drill samples have been performed by reputable, independent third party analytical laboratories.

Taseko implemented a quality control quality assurance (“QAQC”) program consistent with common industry practice after taking over the project in 1991. This program was in addition to the QAQC procedures used internally by the analytical laboratories. The results of this program indicate that analytical results are of high quality and suitable for use in detailed modeling and resource evaluation studies.

Details of sample preparation, assay laboratories, security, and data verification used in the drill hole sampling and analytical programs is documented in the Prosperity Technical Report.

Progressive metallurgical studies over the period 1991 through 1993 included batch and locked cycle flotation tests on composites representing different areas of the deposit to determine achievable copper and gold recoveries and provide detailed concentrate analysis, grind-ability assessments, tailings settling tests, environmental data, and a cursory examination of the removal of deleterious elements from flotation concentrate.

In 1996 a run-in pilot plant was carried out as a precursor to a comprehensive pilot plant; its main objectives to establish basic operating parameters and generate material for initial environmental testing.

In 1997 a pilot plant campaign included batch and locked cycle tests as well as pilot plant runs carried out on composites prepared representing different zones of the deposit. It also included grinding test work, detailed analysis of concentrates, generation of environmental data, tailings settling tests, and concentrate settling and filtration tests.

A test work program was completed in 2008 to investigate the metallurgical performance of Prosperity mineralization at coarser regrinds and alternate regrind flow sheets. This work was conducted on core from the 2007 drilling campaign that represented years 1 through 4 mill feed.

The results support estimated life of mine recoveries of copper and gold recoveries of 87% and 69% respectively using conventional flotation methods.

Estimated average concentrate grades over the mine life are 24% copper, 35 g/t gold and 89 g/t silver. Smelter penalties are anticipated for arsenic, antimony, and mercury.

Additional details with respect to metallurgical test work can be found in the Prosperity Technical Report.

The mineral resources and mineral reserves are as documented in the 2009 Prosperity Technical Report.

The reserve estimate uses long-term metal prices of US$1.65/lb for copper and US$650/oz for gold and a foreign exchange of CDN$1.00=US$ 0.82.

Cautionary Note to Investors concerning estimates of Measured and Indicated Resources

The mineral resources shown in Table 17 include the mineral reserves shown in Table 16. Resource estimates are based on a copper cut-off of 0.14% .

Category	Tonnes (millions)	Gold (g/t)	Copper (%)

The proposed mine plan utilizes a large-scale conventional open pit mining and milling operation. Following a one and a half year pre-strip period, total material mined from the open pit over years 1 to 31 averages 170,000 tonnes per day at a life-of-mine strip ratio of 1.5:1. A declining net smelter return cut-off is applied to the mill feed, which defers lower grade ore for later processing. The stockpiled ore is processed in the final years of the mine plan.

The processing plant has been designed with a nominal capacity of 70,000 tonnes per day. The plant consists of a single 12 meter diameter SAG mill, two 7.9 -metre diameter ball mills, followed by processing steps that include bulk rougher flotation, regrinding, cleaner flotation, thickening and filtering to produce a copper-gold concentrate. Expected life-of-mine metallurgical recovery is 87% for copper and 69% for gold, with annual production averaging 110 million pounds copper and 234,000 ounces gold over the 33-year mine life.

The copper-gold concentrate will be hauled with highway trucks to an expanded load-out facility at Gibraltar Mines Ltd.’s existing facility near Macalister for rail transport to various points of sale, but primarily through the Port of Vancouver for shipment to smelters/refineries around the world.

Power is proposed to be supplied via a new 124 km long, 230 kV transmission line from Dog Creek on the BC Hydro Grid. The Company does not yet have rights of way or approvals to construct facilities to provide electricity to the site. Ample water is available nearby for a mining operation.

The Canadian National railway services Williams Lake and has rolling stock available to move concentrates by rail to points of sale in North America.

Infrastructure would also include the upgrade of sections of the existing road to the site, construction of a short spur to the mine site, an on-site camp, equipment maintenance shop, administration office, concentrator facility, warehouse, and explosives facilities.

The project would employ up to 460 permanent hourly and staff personnel. In addition, approximately 60 contractor personnel would be employed in areas including catering, concentrate haulage, explosives delivery, and busing.

The City of Williams Lake is sufficiently close and is capable of supplying goods, services, and personnel to a mine.

Between 2009 and 2010, the British Columbia Environmental Assessment Office (“EAO”) led a review of the Project in a coordinated manner with the CEAA.

On January 14, 2010, Taseko received the environmental assessment certificate for the Prosperity Project from the Province of B.C.

The Federal process was conducted by a three-person panel, whose findings were in certain respects similar to the conclusions reached in the Provincial Environmental Assessment, although they were not mandated to assess positive economic and social value generated by the project. In July 2010, the panel submitted its final report to the Federal Government.

In November 2010, the Federal Minister of Environment announced that the Prosperity mine project, as proposed, would not be granted federal authorizations to proceed. The Company reviewed and revised its plan and put forth a new design proposal, the New Prosperity project, which included the preservation of Fish Lake by relocating the tailings storage facility and modifying the water management plan. This design addressed the concerns identified during the federal review process, and in February 2011 the Company submitted a project description for the New Prosperity project to the Federal Government.

In June 2011, Taseko submitted an application to the EAO to amend the Environmental Assessment Certificate in accordance with the New Prosperity project description

On September 20, 2012, the Environmental Impact Statement (EIS) was submitted to the three-member Review Panel (the “Panel”) established for the federal environmental assessment of the project. Following the public hearings conducted in Williams Lake and several First Nation communities in the region in July and August 2013, the Panel prepared their report and submitted it to the Federal Minister of the Environment on October 31, 2013.

The Panel report found that the proposed project is not likely to cause significant adverse environmental effects in respect of 33 different areas provided effective mitigation was undertaken but found significant adverse environmental effects were likely in relation to three matters: (i) water quality in Fish Lake and Wasp Lake; (ii) fish and fish habitat in Fish Lake, wetlands and riparian ecosystems; and (iii) Tsilhqot’in current use of lands for traditional purposes, cultural heritage and archaeological/historical resources.

On November 29, 2013, the Company filed an application for judicial review in the Federal Court, seeking to set aside certain findings of the Panel report. The Company is asking the court for a declaration that certain findings relating to seepage and water quality be set aside, and that the Panel failed in certain respects to comply with principles of procedural fairness and the rules of natural justice.

On February 26, 2014, the Minister of the Environment announced her conclusion, based on the Panel report, that the New Prosperity Mine project is likely to cause significant adverse environmental effects that cannot be mitigated. In accordance with the requirements of the Canadian Environmental Assessment Act, 2012, she referred the matter to the Governor in Council who decided that those effects are not justified in the circumstances.

On March 26, 2014, the Company filed an application for judicial review in Federal Court, seeking to quash the decisions of the Minister and Governor in Council communicated on February 26, 2014. The Company is also seeking a declaration that certain sections of the Canadian Environmental Assessment Act, 2012, are in whole or in part beyond the powers of the Federal government under the Constitution Act, 1867.

On August 21, 2014, the Company applied to the Federal Court to convert both judicial reviews into a civil action for damages. The motion was denied with the court suggesting that the company’s concerns were best dealt with in the judicial review process.

On January 14, 2015, the British Columbia Minister of Environment granted the Company a five-year extension to the Environmental Assessment Certificate for Prosperity. The original Prosperity Environmental Assessment Certificate from the Province of British Columbia is subject to an ongoing amendment process to reflect the changes made in the New Prosperity mine design.

On February 12, 2016, the Company announced that it had filed a civil claim in British Columbia Supreme Court against the Canadian federal government. The claim seeks damages in relation to the February 26, 2014 decision concerning the New Prosperity Project in that the Government of Canada and its agents failed to meet the legal duties that were owed to Taseko and that in doing so they caused and continue to cause damages, expenses and loss to Taseko.

Taseko is proceeding with its request to amend the British Columbia environmental assessment certificate for the New Prosperity Project. In addition, Taseko has filed a Notice of Work (“NOW”) with the Ministry of Energy & Mines which will allow the Company to gather information to advance mine permitting under the Mines Act British Columbia.

The two Judicial Reviews initiated by Taseko were heard in federal court over a five day period in the week of January 30, 2017. Both Judicial Reviews focus on the principles of administrative and procedural fairness. Taseko’s allegation is that the Government of Canada, through the conduct of the environmental assessment and the decisions which resulted from it, failed in their obligation to uphold those fundamental principles. A decision is expected from the court within six to nine months

The direct and indirect capital cost to bring the Prosperity Project into production at a design ore throughput rate of 70,000 tonnes per day was estimated in 2009 to be $814 million as summarized in Table 18.

Description	(in millions)
Site Preparation	$10
Mining	$68
Crushing, Conveying & Stockpiling	$52
Concentrator	$227
Tailings Disposal & Reclaim Water	$22
Site Infrastructure	$96
Offsite Infrastructure	$55
Total Direct Costs	$530
Total Indirect Costs	$161
Owners Costs	$19
Contingency	$104
Total Project Costs	$814

The capital cost estimate is expressed in constant 2nd quarter 2009 Canadian dollars using exchange rates of $US:$CDN of 0.95 and $EURO:$CDN of 0.65.

The sustaining and additional equipment capital cost estimate was $701 million over the operating life-of-mine and is summarized in Table 19.

Description	(in millions)
Additional Mining Equipment	$248
Equipment Replacement	$274
Tailings	$113
Concentrator and Infrastructure	$30
Closure	$36
Total	$701

The operating costs for the Prosperity Project, including mining, milling, and general and administrative costs have been estimated in the second quarter of 2009 Canadian dollars and include no allowance for escalation or exchange rate fluctuations.

The average project site operating cost for the 33 year life-of-mine was estimated to be $7.51/tonne of ore milled.

The estimated life of mine average unit costs for each major operating area are shown in Table 20.

Operating Category	Site Operating Cost ($/tonne)
Mining	$3.14
Milling	$3.85
General and Administrative	$0.52
Total	$7.51

The 2009 Prosperity Technical Report used metal prices of US$650/oz gold, US$10.00/oz silver, and US$1.65/lb copper, and an exchange rate of $0.82 USD per CDN$. These were conservative values, well below long term forecast prices at the time and were used solely as the basis for determining the mineral reserve.

Key indicators derived from an economic analysis of the project at reserve metal prices only are summarized in Table 21 and are in constant 2^nd quarter 2009 CDN$.

Total copper production	1,655,000 tonnes/3,648,000,000 lbs
Total gold production	7,720,000 troy oz
Total silver production	19,800,000 troy oz
Mine Life	33 years
Pre-tax return on investment (ROI)	10.0%
Pre-tax payback period	8 years
Annual average net pre-tax cash flow (years 1-33)	$100,000,000
Pre-tax NPV (at 7.5%)	222,000,000
Pre-production capital cost	$814,000,000
LOM sustaining capital	$701,000,000
LOM average site operating costs	$7.51/t ore processed
LOM average off property costs	$3.06/t ore processed
LOM average cost (net of by-product credits)*	US$0.59 per lb copper produced

The basis for capital and operating cost estimates are documented in the 2009 Prosperity Technical Report.

Taseko’s current focus is on pursuing both judicial reviews, the civil action, and the provincial Environmental Assessment Certificate Amendment for New Prosperity.

The Company has evaluated the current project design and potential tailings alternatives to achieve the best environmental protection in terms of both dam stability and potential impacts to water quality. The evaluation considered best practices and best available technologies, tailings storage locations, and water balance. The evaluation is consistent with the province’s requirement for all projects to undergo an assessment of alternative means of undertaking the project with respect to options for tailings management and clarified any previous misconceptions with respect to all aspects of seepage control and water management.

In November 2016, the Company applied for a permit to conduct a site investigation program to collect the data required to complete the detailed engineering required in support of a B.C. Mines Act Permit application. Taseko anticipates the site investigation permit approval in the first quarter of 2017.

There are a number of risks that may have a material and adverse impact on the future operating and financial performance of Taseko and could cause the Company’s operating and financial performance to differ materially from the estimates described in forward-looking statements relating to the Company.

Changes in the market price of copper, gold and other metals, which are volatile and have fluctuated widely, affect the profitability of our operations and financial condition.

Our profitability and long-term viability depend, in large part, upon the market price of metals, primarily copper, but potentially gold and other metals and minerals. The market price of copper is volatile and is affected by numerous factors beyond our control, including:

The copper market is volatile and cyclical and consumption of copper is influenced by global economic growth, trends in industrial production, conditions in the housing and automotive industries and economic growth in China, which is the largest consumer of refined copper in the world. Should demand weaken and consumption patterns change, in particular, if consumers seek out lower cost substitute materials, the price of copper could be adversely affected, which could negatively affect our results of operations.

A decrease in the market price of copper, gold and other metals would affect the profitability of the Gibraltar Mine and our ability to finance the exploration and development of our other mineral properties, which would have a material adverse effect on our financial condition and results of operations. There can be no assurance that the market price of copper and other metals will remain at current levels or that such prices will improve. If commercial quantities of copper, gold and other metals are discovered, there is no assurance that a profitable market will exist or continue to exist for a production decision to be made or for the ultimate sale of the metals.

Fluctuations in foreign currency exchange rates could have an adverse effect on our results of operations and financial condition.

Fluctuations in the Canadian dollar relative to the US dollar could significantly affect our business, results of operations and financial condition. As our Gibraltar Mine operation is located in Canada, our costs are incurred primarily in Canadian dollars. However, our revenue is based on the market price of copper and other metals and is denominated in United States dollars. A strengthening of the Canadian dollar relative to the United States dollar will reduce our profitability, adversely affect our financial condition, and may also affect our ability to finance our development projects. We do not currently enter into foreign currency contracts to hedge against currency risk.

Mining is inherently risky and operations are subject to conditions or events beyond our control, which could have a material adverse effect on our business.

These risks could result in injury or death, environmental damage, damage to, or destruction of, mineral properties, production facilities or other properties, delays in mining, increased production costs, monetary losses, and possible legal liability. We may not be able to obtain insurance to cover these risks at economically feasible premiums. Insurance against certain environmental risks, including potential liability for pollution or other hazards as a result of the disposal of waste products occurring from production, is not generally available to us or to other companies within the mining industry. We may suffer a material adverse impact on our business if we incur losses related to any significant events that are not covered by insurance policies.

The need for infrastructure could delay or prevent us from developing our more advanced projects.

Completion of the development of our advanced projects is subject to various requirements, including government permitting and the need to establish power, water and transportation facilities. The lack of availability on acceptable terms or the delay in the availability of any one or more of these services could prevent or delay development of our advanced projects. If adequate infrastructure is not available in a timely manner, there can be no assurance that:

We are subject to extensive governmental regulation of all aspects of our business.

Our operations and exploration and development activities are subject to extensive federal, provincial, state and local laws and regulations governing various matters, including:

Failure to secure approvals or comply with applicable laws and regulations may result in civil or criminal fines or penalties or enforcement actions, including orders issued by regulatory or judicial authorities enjoining or curtailing operations or requiring corrective measures, installation of additional equipment or remedial actions, any of which could result in the Company incurring significant expenditures. We may also be required to compensate private parties suffering loss or damage by reason of a breach of such laws, regulations or permitting requirements. It is also possible that future laws and regulations, or a more stringent enforcement of current laws and regulations by governmental authorities, could cause additional expense, capital expenditures, restrictions on or suspensions of our operations and delays in the development of our properties.

Although the Company has exercised reasonable due diligence with respect to determining title to properties it owns or leases, there is no guarantee that title to such properties and other tenure will not be challenged or impugned. No assurances can be given that there are no title defects affecting the properties. There may be valid challenges to the title of the Company’s properties which, if successful, could make the Company unable to operate its properties as planned or permitted, or unable to enforce its rights with respect to its properties. In British Columbia the rights of aboriginal peoples and their claims to much of the Province are not settled.

Government regulations relating to mineral rights tenure, permission to disturb areas, land use and the right to operate can adversely affect the Company. The Company’s exploration, development and operations will require permits, licenses and approvals from various governmental authorities.

Although the Florence Copper Project was permitted historically, and Florence Copper has obtained a number of the required permits, licenses and approvals, Florence Copper is currently updating and amending certain permits through a well-defined amendment process, but there can be no assurance as to the outcome of this process. There are, and may in the future be, legal challenges to the validity of permits, licenses and approvals obtained by Florence Copper, and there can be no assurance that such challenges will successfully be defeated. Obtaining, updating and defending the necessary governmental permits, licenses and approvals is a complex, time-consuming and costly process, the success of which is contingent upon many variables outside of the Company’s control. Obtaining, updating, or defending permits, licenses and approvals may increase costs and cause delays depending on the nature of the activity to be permitted and the interpretation of applicable requirements implemented by the permitting authority.

There can be no assurance that all necessary permits, licenses and approvals will be obtained or updated on a timely basis in order for the Company to carry out planned exploration, development or operational activities on its properties, including the planned development of the Florence Copper, Aley and New Prosperity projects, and, if obtained or updated, that the costs involved will not exceed those that the Company has estimated. It is possible that the costs and delays associated with the compliance with the standards and regulations under such permits, licenses and approvals could result in the Company not proceeding with the development or operation of its projects.

Changes in government rules, regulations or agreements, or their application, may negatively affect the Company’s ownership rights, its access to or its ability to advance the exploration and development of its mineral properties.

The government currently has in place or may in the future implement laws, regulations, policies or agreements that may negatively affect the Company’s ownership rights with respect to its mineral properties or its access to the properties. These may restrain or block the Company’s ability to advance the exploration and development of its mineral properties or significantly increase the costs and timeframe to advance the properties

As described elsewhere herein, the New Prosperity has been subject to litigation in regards to the federal Canadian government’s review of the environmental impact of the project. The outcome of the litigation is highly uncertain.

We are solely dependent on the Gibraltar Mine for revenues and suspension of production at that mine would materially adversely affect our business.

The Florence Copper, Aley, New Prosperity and the Harmony projects are in various stages of development. However, until these other projects are developed and operational and are beginning to produce revenue, we are dependent solely upon the Gibraltar Mine for revenues. If the Gibraltar Mine were to cease production for any reason, it would have a material adverse effect on our results of operations, business and financial position.

We have not received the permits necessary to mine all of our proven and probable reserves that are economically recoverable and we may never receive them In order to develop our proven and probable reserves, we must receive various governmental permits. We can give no assurances that we will be able to obtain the governmental permits that we would need to continue developing our proven and probable reserves. Furthermore, we may not be able to mine any of our proven and probable reserves as profitably as we mine at our current operations.

Our mining operations are conducted on properties owned, subject to claims or leased by us from provincial and state governments. We may not be able to negotiate new leases or obtain contracts for properties containing surface, underground or subsidence rights necessary to develop any of our proven and probable reserves at the Florence Copper, New Prosperity or Aley projects. Additionally, our leasehold interests could potentially be at risk if mining operations are not commenced during the term of the lease.

Our projects, which are still under development, may not achieve anticipated production capacity, may experience unanticipated costs or may be delayed or not completed at all.

The Florence Copper, Aley, New Prosperity and Harmony projects are at various stages of development. The development of a project is a complex and challenging process that may take longer and cost more than predicted, or may not be completed at all. In addition, anticipated production capacity may not be achieved. We may encounter unforeseen geological conditions or delays in obtaining required construction, environmental or operating permits or mine design adjustments. Construction delays cause reduced production and cash flow while certain fixed costs, such as minimum royalties or loan payments, may still have to be paid on a predetermined schedule.

As our existing copper and molybdenum offtake agreements expire, our revenues and operating profits could be negatively impacted if we are unable to extend existing agreements or enter into new agreements due to competition, changing copper and molybdenum purchasing patterns, or other variables.

As our copper and molybdenum offtake agreements at the Gibraltar Mine expire, we will compete with other copper and molybdenum suppliers to renew these agreements or to obtain new sales. If we cannot renew these copper and molybdenum supply agreements with our customers or find alternate customers willing to purchase our copper and molybdenum, our revenue and operating profits would suffer.

Our customers may decide not to extend existing agreements or enter into new long-term contracts or, in the absence of long-term contracts, may decide to purchase less copper and molybdenum than in the past or on different terms, including under different concentrate pricing terms. To the degree that we operate outside of long-term contracts, our revenues are subject to pricing in the concentrate spot market that can be significantly more volatile than the pricing structure negotiated through a long-term copper and molybdenum concentrate supply agreement. This volatility could adversely affect the profitability of our operations if conditions in the spot market pricing for copper and molybdenum concentrate are unfavourable.

All of Taseko’s exploration, development, and mining operations are subject to environmental laws and regulations, which can make operations expensive or prohibit them altogether. Many environmental laws and regulations require Taseko to obtain and update permits for its activities from time to time, which may include environmental impact analyses, cultural resources analyses, and public review processes. Taseko must comply with stringent environmental legislation in carrying out work on its projects. Environmental legislation is evolving in a manner that will require stricter standards and enforcement, increased fines and penalties for non-compliance, more stringent environmental assessments of proposed projects and a heightened degree of responsibility for companies and their officers, directors and employees. It is possible that future changes in environmental laws, regulations and permits, or changes in their enforcement or regulatory interpretation, could increase the cost of, or altogether prohibit, carrying out exploration, development, or operation of its projects or any other properties Taseko may acquire. Further, compliance with new or additional environmental legislation may result in delays to the exploration and development activities. It is possible that future changes in applicable laws, regulations and permits or changes in their enforcement or regulatory interpretation could have a significant impact on some portion of Taseko’s business, causing those activities to be economically re-evaluated at that time.

Taseko may be subject to potential risks and liabilities associated with the protection of the environment, as a result of its mineral exploration, development and production. To the extent that Taseko is subject to environmental liabilities, the payment of such liabilities or the costs that it may incur to remedy such liabilities would reduce funds otherwise available to Taseko and could have a material adverse effect on Taseko. If Taseko is unable to fully remedy an environmental liability, it might be required to suspend operations or enter into interim compliance measures pending completion of the required remedy. The potential exposure may be significant and could have a material adverse effect on Taseko.

The Company is or may be subject to legal proceedings related to the development of its projects, its operations, titles to it properties, environmental issues and shareholder or other investor lawsuits. Given the uncertain nature of these actions, the Company cannot reasonably predict the outcome thereof. If the Company is unable to win or favourably settle any lawsuits, it may have a material adverse effect of the Company.

Our business is capital intensive and requires construction of new mines and infrastructure and maintenance of existing operations. Specifically, the exploration, permitting and development of reserves, mining costs, the maintenance of machinery and equipment and compliance with applicable laws and regulations require substantial capital expenditures. While the capital expenditures required to build-out our Gibraltar Mine have been spent, we must continue to invest capital to maintain or to increase the amount of reserves that we develop and the amount of metal that we produce. We make no assurances that we will be able to maintain our production levels or generate sufficient cash flow, or that we will have access to sufficient financing to continue our production, exploration, permitting and development activities at or above our present levels and we may be required to defer all or a portion of our future capital expenditures. Our business, results of operations and financial condition may be adversely affected if we cannot make such capital expenditures.

The New Prosperity Project will require substantial financing, including a possible combination of debt and equity financing. On May 12, 2010, the Company entered into a gold stream transaction agreement with Franco-Nevada Corporation (“Franco-Nevada”), whereby the Company may receive funding in staged deposits totalling US$350 million. The investment by Franco-Nevada is subject to (among other conditions) the condition precedent that the New Prosperity project plan that we had agreed with them must receive appropriate governmental approval. Because our revised New Prosperity project plan is not the one we agreed with Franco-Nevada in 2010, this condition will not be satisfied, and so Franco-Nevada may currently terminate this agreement on ten business days’ written notice to Taseko. However, we believe Franco-Nevada currently has no economic incentive to do so. If our revised mine proposal is ultimately accepted by the authorities, we intend to seek Franco-Nevada’s agreement to reconfirm the terms of our gold stream transaction with them, but there is no assurance that Franco-Nevada will agree to provide such reconfirmation. The investment by Franco-Nevada is also subject to certain other conditions precedent which the Company may not be able to satisfy. There can be no assurance that gold stream, debt or equity financing will be available on acceptable terms. Other risks include those typical of large mine development projects, including the general uncertainties inherent in engineering and construction costs, the need to comply with generally increasing environmental regulation, opposition by First Nations and environmental groups, and accommodation of local and community concerns. The economics of the feasibility study are sensitive to the US dollar and Canadian dollar exchange rate, and this rate has been subject to large fluctuations in the last several years.

Our ability to operate our company efficiently could be impaired if we lose key personnel or fail to continue to attract qualified personnel.

We manage our business with a number of key personnel at each location, including key contractors, the loss of a number of whom could have a material adverse effect on us. In addition, as our business develops and expands, we believe that our future success will depend greatly on our continued ability to attract and retain highly-skilled and qualified personnel and contractors. We cannot be certain that key personnel will continue to be employed by us or that we will be able to attract and retain qualified personnel and contractors in the future. Failure to retain or attract key personnel could have a material adverse effect on us.

Increased competition and poor mining capital markets could adversely affect our ability to attract necessary capital funding, could increase project development costs, and could adversely affect our ability to acquire suitable mineral properties for development in the future.

The mining industry is intensely competitive. Significant competition exists for the acquisition of properties producing or capable of producing copper, gold or other metals. We may be at a competitive disadvantage in acquiring additional mining properties because we must compete with other individuals and companies, many of which have greater financial resources, operational experience and technical capabilities than we do. We may also encounter increasing competition from other mining companies in our efforts to hire experienced mining professionals. Increased competition could adversely affect our ability to attract necessary capital funding, or to acquire it on acceptable terms, or acquire suitable producing properties or prospects for mineral exploration in the future.

Increased demand for and cost of services and equipment could cause project costs to increase materially, resulting in delays if services or equipment cannot be obtained in a timely manner due to inadequate availability, and increased potential for scheduling difficulties and cost increases due to the need to coordinate the availability of services or equipment, any of which could materially increase project exploration, development or construction costs, result in project delays, or both.

The Company has in the past been subject to and may in the future become the target of shareholder activist activities. The effects of shareholder activist activities could have a negative effect on the Company and its business. The Company cannot predict with certainty the outcome of any future shareholder activist activities.

The Company has not paid dividends to date and the Company has no plans to pay a dividend in the foreseeable future.

Taseko’s share capital consists of an unlimited number of no par value common shares. As of March 15, 2017, there were 224,147,134 common shares and 5,000,000 share purchase warrants issued and outstanding. All shares are required by law to be issued only as fully paid and non-assessable.

The holders of Taseko’s common shares are entitled to one vote for each share on all matters submitted to a vote of shareholders.

There have been no changes in the classification of common shares (reclassifications, consolidations, reverse splits or the like) within the previous five years. All common shares of Taseko rank pari passu (i.e. equally) for the payment of any dividends and distributions in the event of a wind-up.

There are no constraints imposed on the foreign ownership of securities of Taseko, however an acquisition of control of Taseko by a non-Canadian would be subject to a review by the Canadian government under its foreign investment laws if the aggregate acquisition price were to exceed certain thresholds all of which are much higher than the Company’s current implied value.

In April 2011, the Company completed a public offering of US$200 million in senior unsecured notes (the “Notes”). The Notes mature on April 15, 2019 and bear interest at a fixed annual rate of 7.75%, payable semi-annually. The Notes are unsecured obligations guaranteed by the Company’s subsidiaries and the subsidiary guarantees are, in turn, guaranteed by the Company. The Notes are redeemable by the Company at a price equal to 101.938%, and the redemption price declines to 100% after April 2017. The Notes are also repayable upon a change of control at a price of 101%. There are no maintenance covenants with respect to the Company's financial performance. However, the Company is subject to certain restrictions on asset sales, incurrence of additional indebtedness, issuance of preferred stock, dividends and other payment restrictions.

On January 29, 2016, the Company entered into a US$70 million Senior Secured Credit Facility (the “Credit Facility”) with EXP T1 Ltd., an affiliate of Red Kite. The Credit Facility consists of an initial tranche of US$33.2 million which has been used to repay the Curis secured loan, and the remainder of the Credit Facility was drawn down in the second quarter of 2016, and is being used by the Company for general corporate purposes. Amounts drawn under the Credit Facility accrue interest on a monthly basis at a rate of three-month Libor plus 7.5% per annum, subject to a minimum Libor of 1% per annum. The loan principal and all accrued interest is payable upon maturity of the Credit Facility. The Credit Facility was subject to an up-front arrangement fee of 2.5% paid by Taseko and there are no commitment fees on any undrawn portion of the facility. The Credit Facility matures on March 29, 2019, as the Company exercised its option and paid an extension fee in June 2016. The Credit Facility is repayable without penalty at any time and does not impose any off-take obligations on the Company.

The Credit Facility is secured by a first priority charge over Taseko’s assets, including the Company’s 75% joint venture interest in the Gibraltar Mine, shares in all material subsidiaries and the Florence Copper Project assets. The Credit Facility is subject to conditions and covenants, including maintenance of a minimum working capital balance of US$20 million. The Company’s balance of working capital (as defined in the Credit Facility agreement) was approximately US$40 million at December 31, 2016.

In connection with the Credit Facility, the Company has issued a call option for 7,500 tonnes of copper with a strike price of US$2.04 per pound. The call option matures in March 2019 and an amount will be payable to Red Kite based on the average copper price during the month of March 2019, subject to a maximum amount of US$15 million.

The Company also issued share purchase warrants to acquire 4 million common shares of the Company at any time until May 9, 2019 at an exercise price of $0.51 per share in connection with the Credit Facility. In February 2017, the Company issued 2 million common shares to Red Kite for proceeds of $1.0 million, upon the partial exercise of warrants that were issued in connection with the Credit Facility.

The following table sets out the ratings of Taseko’s senior notes by the rating agencies indicated as at March 15, 2017:

	Rating Agency
	Standard & Poor’s Rating Services	Moody’s Investor Services
Senior Notes	B-	Caa1
Trend / Outlook	Stable	Stable

Standard & Poor’s Rating Services’ (“S&P”) credit ratings are on a long-term rating scale that ranges from AAA to D, which represents the range from highest to lowest quality of such securities rated. S&P has assigned Taseko a corporate credit rating of B-/Stable. According to S&P, this rating generally means the relevant issuer is vulnerable, but currently has the capacity to meet its financial commitments. Adverse business, financial, or economic conditions will likely impair the capacity or willingness to meet its financial commitments. The stable outlook reflects S&P’s expectation that the Company will have sufficient source of liquidity to fund its operations at least over the next 12 months. The ratings from AAA to D may be modified by the addition of a plus (+) or a minus (-) sign to show relative standing within the major categories. In addition, S&P may add a rating outlook of “positive”, “negative” or “stable” which assesses the potential direction of a long-term credit rating over the intermediate term (typically six months to two years).

Moody’s Investor Services’ (“Moody’s”) credit ratings are on a long-term debt rating scale that ranges from AAA to Caa, which represents the range from highest to lowest quality of such securities rated. Moody’s has assigned Taseko a corporate family credit rating of B3 and a credit rating of Caa1 on the senior notes. According to Moody’s this rating generally means that the obligations are considered to be speculative and are subject to high credit risk. Moody’s appends numerical modifiers 1, 2 and 3 to each generic rating classification from AA through C. The modifier 1 indicates that the security ranks in the higher end of its generic rating category, the modifier 2 indicates a mid-range ranking and the modifier 3 indicates a ranking in the lower end of the generic category.

The credit ratings accorded to the senior notes by S&P and Moody’s are not recommendations to purchase, hold or sell the senior notes as such ratings do not comment as to market price or suitability for a particular investor. There is no assurance that any rating will remain in effect for any given period of time or that any rating will not be revised or withdrawn entirely by a rating agency in the future if, in its judgment, circumstances so warrant.

Management of the Company requests approval from the Audit and Risk Committee for all audit and non-audit services to be provided by the Company’s auditors. The Audit and Risk Committee pre-approves all such services with set maximum dollar amounts for each itemized service. During such deliberations, the Audit and Risk Committee assesses, among other factors, whether the services requested would be considered “prohibited services” as contemplated under Canadian independence standards and by the US Securities and Exchange Commission, and whether the services requested and the fees related to such services could impair the independence of the auditors. No audit-related fees, tax fees or other non-audit fees for such “prohibited services” were approved by the Audit and Risk Committee.

In furtherance of this purpose, the Committee shall have the following responsibilities and authority:

(i) Subject to the law of British Columbia as to the role of the Shareholders in the appointment of independent auditors, the Committee shall have the sole authority to appoint or replace the independent auditor.

(ii) The Committee shall be directly responsible for the compensation and oversight of the work of the independent auditor (including resolution of disagreements between management and the independent auditor regarding financial reporting) for the purpose of preparing or issuing an audit report or related work.

(iv) The Committee shall approve in advance all audit and permitted non-audit services with the independent auditor, including the terms of the engagements and the fees payable; provided that the Committee Chairman may approve services to be performed by the independent auditors and the fee therefor between Committee meetings if the amount of the fee does not exceed $50,000, provided that any such approval shall be reported to the Committee at the next meeting thereof. The Committee may delegate to a subcommittee the authority to grant pre-approvals of audit and permitted non-audit services, provided that the decision of any such subcommittee shall be presented to the full Committee at its next scheduled meeting.

(v) At least annually, the Committee shall review and evaluate the experience and qualifications of the lead partner and senior members of the independent auditor team.

(vi) At least annually, the Committee shall obtain and review a report from the independent auditor regarding:

Section 3.1(4) states that each audit committee member must be financially literate.

“For the purposes of this Instrument, an individual is financially literate if he or she has the ability to read and understand a set of financial statements that present a breadth and level of complexity of accounting issues that are generally comparable to the breadth and complexity of the issues that can reasonably be expected to be raised by the issuer’s financial statements.”

Each issuer must have an Audit Committee of at least three members, each of whom:

“is able to read and understand fundamental financial statements, including a company’s balance sheet, income statement, and cash flow statement. Additionally, each issuer must certify that it has, and will continue to have, at least one member of the audit committee who is financially sophisticated, in that he or she has past employment experience in finance or accounting, requisite professional certification in accounting, or any other comparable experience or background which results in the individual’s financial sophistication, including but not limited to being or having been a chief executive officer, chief financial officer, other senior officer with financial oversight responsibilities. A director who qualifies as an audit committee financial expert under Item 407(d)(5)(ii) of Regulation S-K …. is presumed to qualify as financially sophisticated.”

Carbonatite deposit	Carbonatite deposits are igneous rocks largely consisting of the carbonate minerals calcite and dolomite, which contain the niobium mineral pyrochlore, rare earth minerals or copper sulphide minerals.

Concentrator	A type of mineral processing facility that converts raw ore from the mine into a metal concentrate that can then be sold to a smelter for further processing.

Epithermal Deposit	A mineral deposit formed at low temperature (50-200°C), usually within one kilometre of the earth’s surface, often as structurally controlled veins.

Flotation	Flotation is a method of mineral separation whereby, after crushing and grinding ore, froth created in a slurry by a variety of reagents causes some finely crushed minerals to float to the surface where they are skimmed off.

NSR	Net smelter return, a general proxy for the gross value of metals derived from concentrates delivered to a smelter for refining.

Mineral Deposit	A deposit of mineralization, which may or may not be ore.

Electrowinning is the process in which an electric current flows between a pair of electrodes (anode & cathode) in a solution containing metal ions (electrolyte). Metal is deposited on the cathode in accordance with the metal’s ability to gain or lose electrons. Since ion deposition is selective, the cathode product is generally high grade and requires little further refining.
