1-1 JOHN T. BOYD COMPANY 1.0 EXECUTIVE SUMMARY 1.1 Introduction BOYD was retained by Smart Sand to complete an independent technical audit of mineral resource and mineral reserve estimates—hereafter referred to as frac sand resource and frac sand reserve estimates—for their active mining operation located in Utica, Illinois (the “Utica Mine”). This report summarizes the results of our audit and satisfies the requirements for Smart Sand’s disclosure of frac sand resources and reserves set forth in Subpart 1300 and Item 601(b)(96) of the SEC’s Regulation S-K (S-K 1300). This is the first technical report summary filed by Smart Sand for the Utica Mine. BOYD’s findings are based on our detailed examination of the supporting geologic, technical, and economic information obtained from: (1) Smart Sand provided files, (2) discussions with Smart Sand personnel, (3) records on file with regulatory agencies, (4) public sources, and (5) nonconfidential BOYD files. Our investigation was performed to obtain reasonable assurance that Smart Sand’s frac sand resource and reserve statements are free from material misstatement. This report provides results of an independent estimate of the frac sand resources and reserves underlying the Utica, Illinois property. The basis for these estimates is a volumetric geologic model estimating the reserves and resources compiled by BOYD in July 2020. Production information supplied by Smart Sand was utilized to adjust the reserve estimate to December 31, 2021. This chapter provides a summary of primary information contained within this technical report summary and is supported by remaining portions of this report including text, figures, and tables. Weights and measurements are expressed in US customary units. Unless noted, the effective date of the information, including estimates of frac sand reserves, is December 31, 2021. 1.2 Property Description Smart Sand’s Utica Mine is a surface mining operation located in LaSalle County, Illinois. Frac sand is extracted from the St. Peter Formation which is extensively mined for frac sand in the area. Smart Sand controls approximately 819 contiguous acres of property which is owned fee simple. The general location of this property (the “Utica Property”) is provided on Figure 3.1.


 
1-2 JOHN T. BOYD COMPANY Smart Sand acquired the Utica operation from Eagle Materials Incorporated (Eagle Materials) in 2020. The mine exploits the St. Peter sandstone formation which generally lies approximately 40 ft to 60 ft below the land surface in the area. 1.3 Geology The Utica Property’s target silica bearing formation is the St. Peter sandstone, which is a massive formation in areal extent and thickness. Aerially, it extends from Minnesota to Arkansas and from Illinois into Nebraska and South Dakota. On a regional basis, the St. Peter ranges in thickness from a few feet to over 700 ft, with a general thickness of 100 ft to 200 ft. In northern Illinois, the thickness can be over 300 ft thick. The surface of the Utica Property is overlain by overburden that ranges in thickness from 57 ft to 77 ft, with an average thickness of approximately 66 ft. The overburden material consists of clay, sandy gravel, peat, and limestone cap rock. Beneath the overburden material is the St. Peter sandstone formation. The St. Peter deposit on the Utica Property is flat lying with no evidence of faulting, and has been eroded to an average thickness of approximately 100 ft. The formation is a white to buff, with fine to medium grained ortho-quartzite. It contains rounded, clear polished sand quartz grains with minor secondary silica and clay cement. Care must be taken in defining the presence of erosion channels, which can replace the critical upper portion of the St. Peter sandstone formation locally. Grain size distribution drives the mine planning. Iron tends to be concentrated near the surface and is visible in orange staining. Iron also increases at the bottom sandstone contact, occurring mostly as pyrite. The deposit is coarser in its top half. Where the upper part of the formation is eroded, multiple mining faces must operate to ensure adequate sand is available to meet product specifications. 1.4 Exploration Based on information provided by Smart Sand to BOYD, we note that there were several exploration drilling programs performed on the Utica Property, the most recent of which was in 2017. Overall, there were 29 holes drilled on the property. However, BOYD utilized the results of only 14 exploration holes to develop the geologic model of the Utica deposit. The lithologic data obtained from the 14 holes, the results of the particle size distribution, and the results of the Stim-Lab analyses, were compiled into a database for input into


 
1-3 JOHN T. BOYD COMPANY the BOYD geologic model, which was the principal source of information used to define the extent of the deposit on the property, the overburden volumes, the sand and waste volumes and tonnages, the corresponding sand product distribution based on particle size, and quality of the St. Peter sand underlying the Utica Property. 1.5 Frac Sand Reserves and Quality This technical report summary provides an estimate of frac sand reserves for Smart Sand’s Utica Mine in accordance with the requirements set forth in S-K 1300. These estimates were independently estimated by BOYD. This report, and previous reports, include a thorough geologic investigation of the property, appropriate modeling of the deposit, development of life-of-mine (LOM) plans, and consideration of the relevant processing, economic (including independent estimates of capital, revenue, and cost), marketing, legal, environmental, socio-economic, and regulatory factors. Smart Sand’s estimated surface mineable frac sand reserves for the Utica Property total 129 million saleable product tons, as of December 31, 2021. Table 1.1 presents the estimated Reserve tons by product (size), that are anticipated to be produced at Smart Sand’s Utica Property. Estimated Reserve Tons By Classification as of December 31, 2021 Tons (000) 20/40-Mesh 40/70-Mesh 70/100-Mesh Total Proven 28,443 55,384 12,637 96,464 Probable 8,781 18,984 4,582 32,347 Total 37,224 74,368 17,219 128,811 Table 1.1: Reserves as of December 31, 2021 The reported reserves include only frac sand which is reportedly owned as of December 31, 2021. It is BOYD’s opinion that extraction of the reported frac sand reserves is technically achievable and economically viable after the consideration of potentially material modifying factors. Projecting the historic sales volume of approximately 0.8 million tons per year, the operation has an expected LOM of approximately 161 years. Composite samples collected during the drilling of the initial exploration holes were tested by Stim-Lab for API RP 19C/ISO 13503-2 proppant sand characteristics. Testing


 
1-4 JOHN T. BOYD COMPANY was performed on the 20/40, 30/50, 40/70, and 70/140-mesh (100-mesh) product sizes. The test results are presented in Table 1.2. NWS, LLC Year 2018 Sample - Average API/ISO Test Results By Product Size API RP19C API RP19C Result Result Recommended Result Result Recommended Test 20/40-mesh 30/50-mesh Specification 40/70-mesh 100-mesh* Specification Sphericity 0.8 0.8 ≥ 0.6 0.7 0.7 ≥ 0.6 Roundness 0.7 0.7 ≥ 0.6 0.6 0.6 ≥ 0.6 Acid Solubility (%) 0.3 0.3 ≤ 2.0 0.3 No Test ≤ 3.0 Turbidity (NTU) 9 12 ≤ 250 7 No Test ≤ 250 K-Value (000 psi) 6 7 - 8 No Test - Clusters None Observed None Observed NA None Observed None Observed NA * Note: Currently, 70/140-mesh proppant sand material does not have an API/ISO specification. Table 1.2: Utica Year 2018 API/ISO Test Results for the Four Sized Samples The test results suggest that the Utica Mine could produce frac sands which meet minimum API/ISO recommended testing characteristics. BOYD notes that the Utica operation has a prior history of selling various frac sand sized products to oil service companies prior to the Smart Sand acquisition in 2020. 1.6 Operations 1.6.1 Mining The Utica Mine produces approximately 800,000 to 1 million tons of finished product per year. The quarry exploits the St. Peter sandstone formation which is extensively mined in the Ottawa-Utica, Illinois area. To produce 800,000 tons of frac sand product, approximately 1 million tons of ROM sand is uncovered, drilled, blasted, and then hauled to the slurry plant. Conventional excavators, front-end loaders, articulated haul trucks and dozers are used to strip the overburden and recover the sand. Initially, 50 ft to 75 ft of overburden is removed prior to exposing the approximately 90 ft thick sand formation. Currently the mine pit operates two, 10-hour shifts, four days per week resulting in a 40-hour work week per shift. A 10-hour Friday shift is added if needed. Generally, there are seven employees on the day shift and five employees on the night shift.


 
1-5 JOHN T. BOYD COMPANY The sand is mined, processed, and stored from one contiguous property. The product is trucked to the nearby Peru rail loadout. Production from the operation commenced in mid-2012. Recent historic run-of-mine (ROM) production and forecast ROM production are illustrated in Tables 1.3 and 1.4: Table 1.3 Historic ROM Production Year Finished Tons (000) 2019 n/a 2020* 722 2021 1,136 est * Acquired partial year Table 1.4: Forecasted ROM Production Tons Year 2022 Year 2023 Year 2024 Year 2025 Year 2026 ROM Production tons (000) 982 982 982 982 982 The average process yield is reported to be 81.5%; as such, 982,000 ROM tons are expected to produce approximately 800,000 tons of finished product. The LOM plan, contained in Chapter 7, assumes a steady-state sales volume in the 800,000 product tons per year range for approximately 150 years through year 2172. Future mine plan production, and hence the longevity of the mine, is directly related to energy market demand for proppant sand. Actual yearly production volumes may, and are likely to, fluctuate significantly based on this demand. 1.6.2 Processing The Utica plant commenced wash plant operations in 2014. Initially, the work-in-process (WIP) sand was railed to a dry process plant in Corpus Christi, Texas. In 2018, a 1.6 million tons per year dry process plant was constructed on-site and is currently utilized. The ROM sand material is hauled to an in-pit feed hopper where it is slurried and pumped to an enclosed wet process plant. Following removal of oversize and waste (< 140-mesh) material, the sand is pumped to a decant facility adjacent to the drying and screening plant. After decanting, the sand is reclaimed, dried, and screened into the various frac sand sizes. Finished product is stored in silos and trucked either to local industrial customers or to their Burlington Northern rail loadout in nearby Peru, Illinois. The wet plant employs typical screen/hydrosizer /cyclone classification and dewatering technology and also has an ultrafine circuit and thickener. The wet plant operates two, 10-hour shifts, four days per week. Concerning the decant shed/dry plant, a drag chain arrangement reclaims dryer sand from the top of the decant pile and conveys the sand


 
1-6 JOHN T. BOYD COMPANY to a 250 tons per hour (tph) natural gas fired dryer. Dry sand is then screened into predominantly 20/40-mesh, 30/50-mesh,40/70-mesh, and 70/140-mesh (100-mesh) finished products. The finished products are stored in four 2,000-ton truck loadout silos before being trucked to customers or the rail loadout. 1.6.3 Infrastructure The Utica Mine is serviced by three phase power that is routed along US highway 6, which runs north of the northern property line. The pipeline providing natural gas supply for the drying equipment is also routed along this corridor. Plant process water is supplied by water collected in the pit and ponds. Additionally, the wash process water is recycled after fines are removed via settling with a flocculent in a thickener and series of constructed ponds. On-site facilities include a scale house, office, shop, and a quality laboratory located in the dry process plant. The operation employs approximately 54 people and staffing varies based on production demand. 1.7 Financial Analysis 1.7.1 Market Analysis Although Smart Sand’s market area is essentially all of the energy basins in the United States and western Canada, we have selectively focused on the Permian, Appalachian, and Denver-Julesburg (DJ) as these are target markets for their frac sand. The Oakdale Mine has advantaged delivered cost to the western basins like the DJ as the Oakdale Mine directly loads onto the Canadian Pacific Railway, a very competitive option for westbound sand to the DJ. Oakdale also own a loadout near the mine which enables them to load directly on the Union Pacific Railway, the favored Permian basin rail. The Utica Mine has access to their nearby Burlington Northern rail loadout which greatly complements the Oakdale facility, especially when moving product to the Appalachian (Marcellus-Utica) basin. Therefore, a high-level overview of demand in these basins follows. Permit submissions for horizontal oil and gas wells in the Permian indicate a continuation of strong drilling ahead. According to InfillThinking, the number of permits


 
1-7 JOHN T. BOYD COMPANY filed per working rig this summer is tracking at multi-year highs as evidenced in Figure 1.1 below. Figure 1.1: Permian Basin HZ Permit Submissions vs. Rigs Over the previous 52 weeks, rig counts in the Permian are up approximately 111%. This has led to increased production for both crude oil and natural gas. For the same time period, crude oil (barrels per day) and natural gas production (thousand cubic feet per day) in the Permian are up 10% and 9%, respectively. As Figure 1.2 illustrates, Permian daily crude oil production is nearing its pre-pandemic impacted peak, while daily natural gas production in the Permian continues to make new records and now stands at 18.6 billion cubic feet per day.

1-8 JOHN T. BOYD COMPANY According to U.S. Energy Information Administration Drilling Productivity Report, drilled but uncompleted wells (DUCs) in the Permian Basin have declined 43% since peaking in July 2020 (refer to Figure 1.3). These data dovetail with increased crude oil and natural gas production in the basin. Figure 1.3: Permian Drilled but Uncompleted Wells Although a majority of this large basin’s sand is sourced from local sand mines, Northern White, Oakdale quality sand remains an important product for many well applications. 1.7.1.1 Appalachian Basin (Marcellus/Utica Play) and Niobrara Basin Although smaller in size than the Permian energy fields, the Appalachian and Nioobrara (DJ) are substantial natural gas and oil plays in North America. Unlike the Permian, the Appalachian and Niobrara import the vast majority of the frac sand. Very few, notable in- basin sand operations exist. This creates an advantaged situation for the Oakdale and Utica mines as they are advantaged, transport wise to the basin and there are few substitutes for NWS. Following the energy downturn in 2019 and thern Covid shutdown in 2020, the basin wellfield activity appears to be rebounding. Horizontal rigs have stabilized over the past two years as can be seen from Figures 1.4 but gas production per rig is substantially higher. Energy companies are drilling longer laterals and optimizing each well pad - 500 1,000 1,500 2,000 2,500 3,000 3,500 4,000 Ja n- 19 Fe b- 19 M ar -1 9 Ap r- 19 M ay -1 9 Ju n- 19 Ju l-1 9 Au g- 19 Se p- 19 O ct -1 9 N ov -1 9 De c- 19 Ja n- 20 Fe b- 20 M ar -2 0 Ap r- 20 M ay -2 0 Ju n- 20 Ju l-2 0 Au g- 20 Se p- 20 O ct -2 0 N ov -2 0 De c- 20 Ja n- 21 Fe b- 21 M ar -2 1 Ap r- 21 M ay -2 1 Ju n- 21 Ju l-2 1 Au g- 21 Permian Drilled but Uncompleted Wells

1-10 JOHN T. BOYD COMPANY Similarly, the DJ basin has seen a rebound in rig count since the Covid shutdown. Both gas and oil rig counts have risen but productivity per well has decreased as can be seen in Figure 1.6. Figure 1.6: Niobrara Oil and Gas Rig Count and Productivity (Source: EIA) Overall gas and oil production remains relatively flat in the basin, but more wells are being drilled to maintain this capacity. Figure 1.7 illustrates the overall yearly gas and oil production in the basin. Figure 1.7: Niobrara Oil and Gas Production (Source: EIA) Having survived the challenging environment of 2019 and 2020, Smart Sand’s operations should continue to prove viable into the future notwithstanding a sustained and significant energy price collapse. Their low-cost mining scheme, advantaged transport to select basins, and high-quality product help to create an advantage compared with other NWS producers.

Air emissions are regulated by the Illinois Environmental Protection Agency.


 
1-14 JOHN T. BOYD COMPANY Based on our review of information provided by Smart Sand and available public information, it is BOYD’s opinion that the Utica Mine’s record of compliance with applicable mining, water quality, and environmental regulations is generally typical for that of the industry. BOYD is not aware of any regulatory violation or compliance issue which would materially impact the frac sand reserve estimate. 1.9 Conclusions It is BOYD’s overall conclusion that Smart Sand’s Utica Mine frac sand reserves, as reported herein: (1) were prepared in conformance with accepted industry standards and practices, and (2) are reasonably and appropriately supported by technical evaluations, which consider all relevant modifying factors. We do not believe there is other relevant data or information material to the Utica Property that would render this technical report summary misleading. Our conclusions represent only informed professional judgment. The ability of Smart Sand, or any mine operator, to recover all of the reported frac sand reserves is dependent on numerous factors that are beyond the control of, and cannot be anticipated by, BOYD. These factors include mining and geologic conditions, the capabilities of management and employees, the securing of required approvals and permits in a timely manner, future sand prices, etc. Unforeseen changes in regulations could also impact performance. Opinions presented in this report apply to the site conditions and features as they existed at the time of BOYD’s investigations and those reasonably foreseeable.

3-1 JOHN T. BOYD COMPANY 3.0 PROPERTY OVERVIEW 3.1 Description and Location Smart Sand’s Utica surface frac sand mining operation is located on a contiguous block of acres controlled by Smart Sand, in LaSalle County, Illinois, and is approximately 6 miles west of the city of Ottawa. Utica’s off-site rail loadout is in Peru, Illinois approximately 7 miles west of the mining operation. Geographically, the Utica frac sand processing plant is located at approximately 41°20'51.18"N latitude and 88°57'25.85"W longitude. Figure 3.1 illustrates the location and general layout of the Utica Property and Mine. 3.2 History Smart Sand purchased the Utica frac sand operation from Eagle Materials in September 2020. The acquisition included the purchase of the mineral reserves and associated mining and processing facilities. Eagle Materials originally purchased the Utica greenfield property in 2012 and 2013, with mining and wet processing operations commencing in 2014. The Utica operation has mined premium NWS for use in the oil/gas industry. NWS has been extensively mined, via surface mining operations, in the north central area of the United States (predominantly mined in Minnesota, Wisconsin, and Illinois, with lesser amounts mined in Arkansas and Iowa). The primary sources of NWS are from the Saint Peter, Jordan, Wonewoc, and Mt. Simon formations, which are found in an area ranging from south central Minnesota into Wisconsin. Utica’s Mine Safety and Health Administration (MSHA) identification number (1103253) was assigned in 2012. 3.3 Property Control The Utica Property comprises approximately 819 acres owned in fee by Smart Sand. Ownership information provided by Smart Sand has been accepted as being true and accurate for the purpose of this report.


 


 
3-3 JOHN T. BOYD COMPANY 3.3.1 Mineral Ownership Smart Sand owns 100% of the mineral rights to the entire subject property. The current estimated area suitable for resource extraction is approximately 642 acres, or 78% of the total mining property, after observing setbacks, right of ways, processing areas, and other non-mining acreage. 3.3.2 Surface Ownership Smart Sand owns 100% of the surface rights to the entire subject property. 3.4 Adjacent Properties Most of the Illinois frac sand mining activity occurs in LaSalle County, with another operation in nearby Ogle County. Smart Sand’s Utica operation is in LaSalle County. The mining activity in these two counties is in the St. Peter Formation and is for the purpose of producing frac sand. All existing frac sand mining operations in LaSalle County are located either northeast/east or northwest/west of the Utica Mine. 3.5 Regulation and Liabilities Mining and related activities for the Utica operation are regulated by two Federal agencies, three State of Illinois agencies, and two Local agencies. 3.6 Accessibility, Local Resources, and Infrastructure Smart Sand’s Utica Mine is located near a number of small cities in north-central Illinois. Ottawa has a population of about 18,000, while LaSalle County has over 108,000, based on 2019 population estimates. There are nine counties adjacent to LaSalle County, specifically, Lee, DeKalb, Kendall, Grundy, Livingston, Woodford, Marshall, Putnam and Bureau counties. General access to the Utica Mine is via a well-developed network of primary and secondary roads serviced by state and local governments. These roads offer direct access to the mine and processing facilities and are open year-round. Primary vehicular access to the property is via US Highway 6, with nearby access to Interstate 80 and Interstate 39. The Utica operation has an off-site rail loadout facility in nearby Peru, Illinois, approximately 7 miles from the site, with access to the BNSF rail network. Utica’s frac


 
3-4 JOHN T. BOYD COMPANY sand product is railed to the various energy basins via the BNSF or other connecting rail carriers. The Utica operation has access to major airports as there are: • Five International airports within a 90-mile radius of the site. • One Regional airport within an 80-mile radius of the site. • One Local airport in Peru, Illinois. Sources of three phase electrical power, natural gas, and other miscellaneous materials are readily available. Water supplied to the operation is via various sources such as, on-site wells, on-site ponds, and public water. 3.7 Physiography The Utica Property in LaSalle County is in the Bloomington Ridged Plain of the Central Lowland Province, and within the Fox Valley and Illinois River Valley regions in north Illinois. As stated in the Soil Survey of LaSalle County, Illinois, a USDA-NRCS publication1, “The Bloomington Ridged Plain consists mainly of till of Wisconsinan age. It is characterized by low, broad morainic ridges with intervening wide stretches of relatively flat or gently undulating ground moraines2. The moraines form a series of curves roughly concentric with the outer boundary of the county.” “Most of La Salle County is drained by the Illinois River and its tributaries, the Fox, Vermilion, and Little Vermilion Rivers. The Illinois River flows into the Mississippi River, which empties into the Gulf of Mexico.”3 The Illinois River is about 2.5 miles south of the mining property. Starved Rock State Park is about 3 miles southwest of the mining property along the southern bank of the Illinois River. The surface of the Utica Property is overlain by overburden that ranges in thickness from 57 ft to 77 ft, with an average thickness of approximately 66 ft. The overburden material consists of clay, sandy gravel, peat, and limestone cap rock. Beneath the overburden material is the St. Peter sandstone formation, one of the primary sources of NWS.

4-1 JOHN T. BOYD COMPANY 4.0 GEOLOGY 4.1 Regional Geology NWS are generally located in the north-central portion of the United States (predominantly in Minnesota, Wisconsin, and Illinois, with lesser amounts in Arkansas and Iowa). NWS is found in poorly cemented Cambrian and Ordovician sandstones and in unconsolidated alluvial deposits locally derived from these sandstones. The Saint Peter, Jordan, Wonewoc, and Mount Simon Formations, located in south-central Minnesota into Wisconsin, are the primary sources of NWS. Figure 4.1, on the following page, presents the various stratigraphic rock units in Wisconsin, which are similar to the rock units encountered in Illinois. The Utica Property’s target silica bearing formation is the St. Peter Sandstone, which is a massive formation in areal extent and thickness. Areally, it extends from Minnesota to Arkansas and from Illinois into Nebraska and South Dakota. On a regional basis, the St. Peter ranges in thickness from a few feet to over 700 ft, with a general thickness of 100 ft to 200 ft. In northern Illinois, the thickness can be over 300 ft thick. Sand comprising the St. Peter Formation was originally deposited in clear shallow water near the shore of a Paleozoic Sea. The St. Peter sandstone can be generally described as well sorted, well rounded, fine to medium size frosted grains of exceptionally pure quartz sands free from clay, carbonates, and heavy minerals that are friable or weakly cemented. As such, the sand is valued in the marketplace for its high silica content and is extensively quarried for silica sand. The St. Peter sandstone is one of the major aquifers in Illinois. On a regional basis the properties of the formation exhibit grain size that is generally uniform and normally grades from medium to medium-coarse in the upper section, to medium to fine-grained in the lower section. As a rule, the lower portion of the formation is fine-grained with iron, alumina, and carbonate contamination increasing with depth. The St. Peter Formation is of Ordovician age (early middle). It is the lower formation of the Anceli Group and overlies the Shakopee Dolomite. 4.2 Local Stratigraphy The surface of the Utica property is overlain by overburden that ranges in thickness from 57 ft to 77 ft, with an average thickness of approximately 66 ft. The overburden


 


 
4-3 JOHN T. BOYD COMPANY material consists of clay, sandy gravel, peat, and limestone cap rock. Beneath the overburden material is the St. Peter sandstone formation. The St. Peter deposit on the Utica Property is flat lying with no evidence of faulting, and has been eroded to an average thickness of approximately 100 ft. The formation is a white to buff, with fine to medium grained ortho-quartzite. It contains rounded, clear polished sand quartz grains with minor secondary silica and clay cement. Care must be taken in defining the presence of erosion channels, which can replace the critical upper portion of the St. Peter sandstone formation locally. Grain size distribution drives the mine planning. Iron tends to be concentrated near the surface and is visible in orange staining. Iron also increases at the bottom sandstone contact, occurring mostly as pyrite. The deposit is coarser in its top half. Where the upper part of the formation is eroded, multiple mining faces must operate to ensure adequate sand is available to meet product specifications. 4.3 Frac Sand Geology Frac sand is a naturally occurring, high silica content quartz sand, with grains that are generally well-rounded. The main difference between frac sand and other sands is that frac sand grains are relatively pure in composition, consisting almost entirely of quartz; other sands have numerous impurities that may be cemented to the quartz grains. The pure quartz composition of frac sand grains, along with being well-rounded and spherical in shape, gives these sands the characteristics (crush strength, high acid solubility, low turbidity) that are branded as premium sands by the drilling service industry. The NWS-St. Peter sands are generally characterized by a high silica content, high roundness and sphericity, white color, and lack of deleterious material. Because of their monocrystalline structure, these sands have superior grain strength when compared to other silica sands and are suitable for pressure applications generally up to the 9,000-pounds per square inch (psi) range. NWS is not classified as an in-basin frac sand. In-basin frac sands, such as those found in west Texas, are a relatively new extension of the frac sand mining industry. The first in-basin frac sand deposits mined (late-2017) in the United States were in the Permian Basin of Texas. Permian basin oil and gas exploration and production companies noted favorable results from locally sourced sands, and as such, nearly every other energy basin has gone through a period of exploration to locate suitable local sources of frac sands. Many E&Ps shifted their approach from requiring only premium branded frac


 
4-4 JOHN T. BOYD COMPANY sands, such as NWS, to using higher quantities of locally sourced and lower-priced frac sands, with positive results. q:\eng_wp\3555.021 - ss s-k 1300\wp\rpt\section ii - utica reserves\ch-4 - geology.docx


 
5-1 JOHN T. BOYD COMPANY 5.0 EXPLORATION DATA 5.1 Background As previously mentioned, Smart Sand acquired the Utica Property in September 2020 from Eagle Materials. BOYD, in February 2021, prepared a Resource and Reserve Estimate for the Utica Proppant Sand Property as of the date of acquisition, which utilized available exploration information provided to us by Smart Sand. 5.2 Exploration Procedures 5.2.1 Drilling and Sampling Based on information provided by Smart Sand to BOYD, we note that there were several exploration drilling programs performed on the Utica Property, the most recent of which was in 2017. There were 29 holes drilled on the property. However, BOYD utilized the results of only 14 exploration holes to develop the geologic model of the Utica deposit, specifically SL-1 to SL-11 (11 holes), DI-5 (1 hole), EG-3 (1 hole), and LD-3 (1 hole), as they were the only holes with sieve size, overburden and sand thickness data. Also, the sand core in each hole was tested in 10-ft increments for particle size distribution. Smart Sand provided BOYD with the results of two sets of sand samples (Year 2011 and Year 2018) sent to Stim-Lab in Duncan, Oklahoma, for ISO/API analysis. Refer to Section 5.2.2 for further information. The lithologic data obtained from the 14 holes, the results of the particle size distribution, and the results of the Stim-Lab analyses, were compiled into a database for input into the BOYD geologic model, which was the principal source of information used to define the extent of the deposit on the property, the overburden volumes, the sand and waste volumes and tonnages, the corresponding sand product distribution based on particle size, and quality of the St. Peter sand underlying the Utica Property. BOYD notes we were not involved with any exploration activities associated with the information presented above and were not provided information pertaining to the drilling and sampling methodologies utilized in the various exploration campaigns at the Utica Property. Other than the 14 exploration hole data provided by Smart Sand, we were not provided information regarding the equipment utilized, and the sampling, logging, and field work performed pertaining to the exploration work on the Utica property by the prior owners of the property. BOYD notes that we cannot opine on whether those methodologies and procedures used to obtain the exploration data were carefully and


 
5-2 JOHN T. BOYD COMPANY professionally collected, prepared, and documented in conformance with generally accepted industry standards. We can confirm that the Stim-Lab results were professionally prepared and documented in conformance with generally accepted industry standards. BOYD opines that although limited, the data provided were sufficient for the purposes of evaluating and estimating frac sand resources and reserves on the Utica Property. 5.2.2 Frac Sand Quality Testing Stim-Lab performed sieve analyses on two sets of sized-samples pertaining to the Utica Property. In addition, they performed the API RP 19C/ISO 13503-2 proppant sand characteristic tests for sphericity and roundness, acid solubility, crush resistance, and turbidity. These specific sized samples are the following: • Three sand samples labelled Illinois Cement 20/40, Illinois Cement 40/70, and Illinois Cement 70/140 submitted by Eagle Materials on August 3, 2011. • Four sand samples labelled NWS 20/40, NWS 30/50, NWS 40/70, and NWS 100M submitted by Northern White Sand, LLC on August 3, 2018. When the samples were received by Stim-Lab, they performed a sieve analysis on each frac sand product sized sample and tested each product sized sample per API RP 19C/ISO 13503-2 standards. Results from the various testing performed on the Year 2011 and Year 2018 sized sand samples pertaining to the Utica Property is presented in Section 5.3. 5.2.3 Other Exploration Methods No other methods of exploration (such as airborne or ground geophysical surveys) are reported for the Utica Property. 5.3 Laboratory Testing Results The relatively uniform nature of the St. Peter sand formation underlying the Utica Property, combined with the results of independent laboratory testing (Stim-Lab) indicated that the Utica Property could produce a suite of 20/100-mesh frac sand products that meet customer specifications for frac sand use.


 
5-3 JOHN T. BOYD COMPANY 5.3.1 Grain Size Distribution Smart Sand provided BOYD the grain size distribution data, from the 14 holes selected. A table, summarizing the 14 holes average grain size distribution of the in situ sand deposit, based on sieve results, is shown in Table 5.1. Approximate In-Place Product Distribution % Retained By Mesh Size % Product >20 20/40 40/70 70/100 <100 20/40 40/100 1.0 22.2 49.0 12.4 15.4 26.6 73.4 Table 5.1: Average Particle Size Distribution The preceding table highlights the relative size mix of the sand found within the Utica Property, indicating approximately 84% of the sand particles are concentrated between the “passing 20-mesh” and “retained 100-mesh” size fraction. Moreover, of the 20/100-mesh sand faction, approximately 73% of the marketable product consists of the finer 40/100-mesh sands. 5.3.2 Grain Shape (Sphericity and Roundness) Grain shape was analyzed according to ISO 13503-2/API RP19C, Section 7. Under this standard, recommended sphericity and roundness values for proppants are 0.6 or greater, and 0.7 or greater for high strength proppants. As part of the grain shape analysis, the presence of grain clusters (weakly cemented grain aggregates) and their approximate proportion were not observed in the seven sized samples. 5.3.3 Crush Resistance Crush resistance is a key test that determines the amount of pressure a sand grain can withstand under laboratory conditions for a two-minute duration. The sample was analyzed according to ISO 13503-2/API RP19C, Section 11. Under this standard, the highest stress level (psi) in which the proppant produces no more than 10% crushed fine material is rounded down to the nearest 1,000 psi and reported as the “K-value” of the material. 5.3.4 Acid Solubility Acid solubility was analyzed according to ISO 13503-2/API RP19C, Section 8. Under this standard, 5 grams of sand is treated with 100 milliliters of 12:3 hydrochloric acid to hydrofluoric acid at 150oF for 30 minutes. The recommended maximum acid solubility for proppants in the 6/12 through 30/50-mesh size range is 2.0%, and for proppants in the 40/70-mesh and finer size range is 3.0%.


 
5-4 JOHN T. BOYD COMPANY 5.3.5 Turbidity Turbidity was analyzed according to ISO 13503-2/API RP19C, Section 9. Under this standard, the suggested maximum frac sand turbidity should be equal to or less than 250 nephelometric turbidity units (NTU). 5.3.6 Quality Summary The three sized samples, 20/40, 40/70, and 70/140-mesh product sizes, provided to Stim-Lab in August 2011 were tested for API RP 19C/ISO 13503-2 proppant sand characteristics. The test results are presented in Table 5.2.

Table 5.3: Utica Year 2018 API/ISO Test Results for the Four Sized Samples The seven sized samples tested suggest that the Utica Mine could produce frac sands which meet minimum API/ISO recommended testing characteristics. BOYD notes that the Utica operation has a prior history of selling various frac sand sized products to oil


 
5-5 JOHN T. BOYD COMPANY service companies (Eagle Materials1 preacquisition by Smart Sand) and by Smart Sand thereafter. 5.4 Data Verification The December 31, 2021, reserve estimate for the Utica Property is based on historic drill hole data previously provided to BOYD by Smart Sand in the preparation of our prior reserve estimate. It is customary in preparing proppant sand resource and reserve estimates to accept basic drilling and quality testing data as provided by the client, subject to the reported results being judged representative and reasonable. As we have judged the drilling and quality data representative and reasonable, we opine that they are still representative and reasonable for use in the December 31, 2021, resource and reserve estimate. q:\eng_wp\3555.021 - ss s-k 1300\wp\rpt\section ii - utica reserves\ch-5 - exploration.docx 1 2020EM 2020 Annual Report and Form 10-K March 31, 2020, page 19.


 
6-1 JOHN T. BOYD COMPANY 6.0 FRAC SAND RESOURCES AND RESERVES 6.1 Applicable Standards and Definitions Unless otherwise stated, frac sand resource and frac sand reserve estimates disclosed herein are completed in accordance with the standards and definitions provided by S-K 1300. It should be noted that BOYD considers the terms “mineral” and “frac sand” to be generally interchangeable within the relevant sections of S-K 1300. Estimates of any mineral resources and reserves are always subject to a degree of uncertainty. The level of confidence that can be applied to a particular estimate is a function of, among other things: the amount, quality, and completeness of exploration data; the geological complexity of the deposit; and economic, legal, social, and environmental factors associated with mining the resource/reserve. By assignment, BOYD used the definitions provided in S-K 1300 to describe the degree of uncertainty associated with the estimates reported herein. The definition of mineral (frac sand) resource provided by S-K 1300 is: Mineral resource is a concentration or occurrence of material of economic interest in or on the Earth's crust in such form, grade or quality, and quantity that there are reasonable prospects for economic extraction. A mineral resource is a reasonable estimate of mineralization, taking into account relevant factors such as cut-off grade, likely mining dimensions, location or continuity, that, with the assumed and justifiable technical and economic conditions, is likely to, in whole or in part, become economically extractable. It is not merely an inventory of all mineralization drilled or sampled. Estimates of frac sand resources are subdivided to reflect different levels of geological confidence into measured (highest geologic assurance), indicated, and inferred (lowest geologic assurance) The definition of mineral (frac sand) reserve provided by S-K 1300 is: Mineral reserve is an estimate of tonnage and grade or quality of indicated and measured mineral resources that, in the opinion of the qualified person, can be the basis of an economically viable project. More specifically, it is the economically mineable part of a measured or indicated mineral resource, which includes diluting materials and allowances for losses that may occur when the material is mined or extracted.


 
6-2 JOHN T. BOYD COMPANY Estimates of frac sand reserves are subdivided to reflect geologic confidence, and potential uncertainties in the modifying factors, into proven (highest assurance) and probable. Figure 6.1 shows the relationship between frac sand resources and frac sand reserves. Figure 6.1: Relationship Between Frac Sand Resources and Frac Sand Reserves In this report, the term “frac sand reserves” represent the tonnage of frac sand products that meets customer specifications and will be available for sale after processing of the ROM sand. 6.2 Frac Sand Resources 6.2.1 Methodology BOYD had previously estimated the in-place frac sand resources on the property as of the date of acquisition by Smart Sand in September 2020. Incorporating our prior work, which is discussed below, BOYD independently prepared estimates of in-place frac sand resources for the Utica Property, as of December 31, 2021, by performing the following tasks: 1. Available product size distribution data and laboratory testing results, provided by Smart Sand, were compiled into a database for use in modeling the quality and quantity of the mineable sand underlying the Utica Property. The geologic database


 
6-3 JOHN T. BOYD COMPANY utilized 14 of 29 holes, those with complete information including, sieve size, overburden, and sand thickness data. The geologic data was imported into Carlson Software, a geologic modeling and mine planning software suite that is widely used and accepted by the mining industry. 2. A geologic model of the deposit was created in Carlson Software using industry-standard grid modeling methods well-suited for simple stratigraphic deposits, and for estimating overburden and sand volumes and associated product distribution. The geologic model delineates the top and bottom of the mineable sand horizon and the distribution of the product size fractions across the deposit. The top and bottom of the mineable frac sand interval were established as follows: a. Aerial mapping as of July 20, 2020, in conjunction with drilling data, was used as the basis for estimating overburden and sand volumes and associated product distribution in the Carlson geologic modeling program. It was reported to BOYD that no mining was undertaken on the property between July 20, 2020, the date of aerial photography, and September 18, 2020, the date of the acquisition. Accordingly, no adjustments were made for depletion for this period. b. As there is overburden material across the property, which ranges in thickness from 57 ft to 77 ft, the top of the mineable sand interval was defined as the base of the overburden material above the St. Peter sandstone unit. c. The bottom of the mineable sand interval was based primarily on a target mineable thickness of 90 ft. However, drill holes that exhibited higher concentrations of fine materials near their bottoms also defined what depths mining may be terminated. 3. After reviewing the continuity and variability of the deposit, suitable resources classification criteria were developed and applied as per the discussion in Section 6.2.2. 4. BOYD defined the mineable resources within the property as the area defined by management which included a mine plan. A viewshed was incorporated, which involved leaving an earthen berm constructed mainly of overburden and topsoil around the property in order to maintain a shielded view of the future mine from local roadways. Areas on the property that were excluded from being considered mineable were those that had fines and stormwater ponds, or processing facilities constructed, as well as areas directly underlying property boundary viewshed areas. Estimation of the in-place resources assumes mining operations using standard surface excavation equipment, which is widely utilized for mining of similar deposit types. As such, the estimates were subject to the following setbacks and slope requirements: a. 100 ft offset inside of the entire property boundary line. b. A final pit highwall slope of 80 degrees was applied from the top of the pit to the bottom of the mineable sandstone interval. c. The final pit floor was estimated to be at an elevation of between approximately 440 ft mean sea level (msl) and 460 ft msl.


 
6-4 JOHN T. BOYD COMPANY 5. In-place volumes for each of the proposed mining blocks were calculated from the geologic model within Carlson Software. An in-place sandstone dry density of 127 pounds per cubic foot was used to convert the in-place sand volumes to short tons. 6. BOYD utilized provided production data, from the date of acquisition in September 2020 by Smart Sand, to reconcile the estimate from date of volumetric estimate to December 31, 2021. 6.2.2 Classification Geologic assuredness is established by the availability of both structural (thickness and elevation) and quality (size fraction) information for the deposit. Resource classification is generally based on the concentration or spacing of exploration data which can be used to demonstrate the geologic continuity of the deposit. When material variations in thickness, depth, and/or sand quality occur between drill holes, the allowable spacing distance between drill holes is reduced. The following drill hole spacing criteria were established by the Qualified Person after review of the available exploration data and geologic models and used to classify the frac sand resources of the Utica Property: Resource Spacing Requirement (ft) Classification (Nominal Maximum) Measured 1,500 (750 ft radius) Indicated 3,000 (1,500 ft radius) Table 6.1: Utica Property Drill Hole Spacing Parameters The Qualified Person has determined that nearly all of the estimated frac sand resources within the Utica Property are classified as either Measured or Indicated. BOYD is of the opinion that there is a low degree of uncertainty associated with each of the resource classifications. 6.2.3 Frac Sand Resource Estimate There are no reportable frac sand resources excluding those converted to frac sand reserves for the Utica Mine. Quantities of frac sand controlled by Smart Sand within the defined boundaries of the Utica Property which are not reported as frac sand reserves are not considered to have potential economic viability; as such, they are not reportable as frac sand resources. As a note, BOYD did not include the sand material located below the depths of the planned pit floor (between approximately 440 ft and 460 ft msl) in the resource estimate. There is the potential for some areas of this formation to be mineable to greater depths than used to define resources herein. The lower lying sandstone could potentially be


 
6-5 JOHN T. BOYD COMPANY evaluated for resource and reserve consideration in the future, provided additional exploration was conducted and subsequent mine planning was completed to determine the ability to extract the lower lying sand material safely and economically. 6.2.4 Validation BOYD independently estimated in-place frac sand resources for the Utica Mine based on the provided drilling, sampling, and testing data obtained from Smart Sand. Utilizing industry-standard grid modeling techniques we have estimated volumes of frac sand indicated by such data. Based on our review of the information provided by Smart Sand, we are of the opinion that the data provided are reasonable and appropriate. Furthermore, it is our opinion that the estimation methods employed are both appropriate and reasonable for the deposit type and proposed extraction methods. 6.3 Frac Sand Reserves 6.3.1 Methodology Estimates of frac sand reserves for the Utica Mine were derived contemporaneously with estimates of frac sand resources. To derive an estimate of saleable product tons (proven and probable frac sand reserves), the following modifying factors were applied to the in-place measured and indicated frac sand resources underlying the respective mine plan areas: • A 95% mining recovery factor, which assumes that 5% of the mineable (in-place) frac sand resource will not be recovered for various reasons. Applying this recovery factor to the in-place resource results in the estimated ROM sand tonnage that will be delivered to the wet process plant. • An overall 81% processing recovery. This recovery factor accounts for losses in the wet and dry plants. This recovery factor accounts for removal of out-sized (i.e., larger than 20-mesh and smaller than 100-mesh) sand and losses in the wet and dry processing plants due to minor inefficiencies. The overall product yield (after mining and processing losses) for the Utica Mine is estimated at 77%. That is, for every 100 tons of in-place frac sand resources mined, approximately 77 tons will be recovered and sold as product. At the request of Smart Sand, BOYD utilized actual/estimated production data, provided by Smart Sand, from the date of acquisition in September 2020 through December 31, 2021, to reconcile the estimate from the date of volumetric estimate to December 31, 2021.


 
6-6 JOHN T. BOYD COMPANY As previously noted, there are no reportable frac sand resource tons. However, Table 6.2 provides insight into the frac sand in-place resources tons that would be eventually mined and converted into frac sand product tons for the Utica Mine. The frac sand product tons are equivalent to the total reserve tons as of December 31, 2021, for the Utica Mine. Utica Property In-Place, ROM and Product Tons Tons (000) In-Place (a) ROM (b) Product (c) Measured 124,087 117,883 96,464 Indicated 42,379 40,260 32,347 Total 166,466 158,143 128,811 a: In-place tons calculated using an in situ dry density of 127 pcf. b: Run-of-Mine tons calculated using a 94.8% mining recovery. c: Product tons calculated using 77% processing recoveries. Table 6.2: Mineable and Reserve Tons as of December 31, 2021 6.3.2 Classification Proven and probable frac sand reserves are derived from measured and indicated frac sand resources, respectively, in accordance with S-K 1300. BOYD is satisfied that the frac sand reserve classification reflects the outcome of technical and economic studies. Figure 6.2 illustrates the reserve classification of the Utica Property frac sand deposit. 6.3.3 Frac Sand Reserve Estimate Smart Sand’s estimated surface mineable frac sand reserves for the Utica Property total 128.8 million saleable product tons, as of December 31, 2021. The following table presents the estimated Reserve tons by product (size) owned in fee, which are anticipated to be produced at Smart Sand’s Utica Property. Estimated Reserve Tons By Classification as of December 31, 2021 Tons (000) 20/40-Mesh 40/70-Mesh 70/100-Mesh Total Proven 28,443 55,384 12,637 96,464 Probable 8,781 18,984 4,582 32,347 Total 37,224 74,368 17,219 128,811 Table 6.3: Reserves as of December 31, 2021 Of the total frac sand reserves for the Utica Mine as of December 31, 2021, it is our conclusion that approximately 75% of the stated reserves can be classified on the proven reliability category (the highest level of assurance) with the reminder classified as probable.


 


 
6-8 JOHN T. BOYD COMPANY The estimated product distribution of the frac sand reserves is based on available laboratory gradation test data provided by Smart Sand. Grain size distribution and overall yields may vary based on the depth and location at which mining occurs. The Utica Property, and other frac sand operations in the area, have a well-established history of mining and selling frac sand products into the various energy basin fields. BOYD has assessed that sufficient studies have been undertaken to enable the frac sand resources to be converted to frac sand reserves based on current and proposed operating methods and practices. Changes in the factors and assumptions employed in these studies may materially affect the frac sand reserve estimate. The extent to which the frac sand reserves may be affected by any known geological, operational, environmental, permitting, legal, title, variation, socio-economic, marketing, political, or other relevant issues has been reviewed as warranted. It is the opinion of BOYD that Smart Sand has appropriately mitigated, or has the operational acumen to mitigate, the risks associated with these factors. BOYD is not aware of any additional risks that could materially affect the development of the frac sand reserves. Based on our independent estimate and operations review, we have a high degree of confidence that the estimates shown in this report accurately represent the available frac sand reserves controlled by Smart Sand, as of December 31, 2021. q:\eng_wp\3555.021 - ss s-k 1300\wp\rpt\section ii - utica reserves\ch-6 - mineral resources and reserves.docx


 
7-1 JOHN T. BOYD COMPANY 7.0 MINING OPERATIONS 7.1 Mining Method The Utica Mine produces approximately 800,000 to 1 million tons of finished product per year. The quarry exploits the St. Peter sandstone formation which is extensively mined in the Ottawa-Utica, Illinois area. To produce 800,000 tons of frac sand product, approximately 1 million tons of ROM sand is uncovered, drilled, blasted, and then hauled to the slurry plant. Conventional excavators, front-end loaders, articulated haul trucks and dozers are used to strip the overburden and recover the sand. Initially, 50 ft to 75 ft of overburden is removed prior to exposing the approximately 90 ft thick sand formation. The majority of the overburden is excavatable with the exception of thin caprock above the sand which requires drill and blast. Approximately 60,000 tons per month of overburden is stripped, mainly on the day shift, and hauled and dumped into the mined-out area of the pit. Approximately one 90-ft high bench of sandstone is blasted per month. The drilling and blasting is contracted to a third party. A continuous 90 ft shot (no decking) on a 20 ft x 20 ft pattern is generally utilized. The night shift predominantly loads and hauls the sand to the dump hopper. Approximately 6,000 to 9,000 tons of ROM sand is generally hauled per 10-hour shift.


 
7-2 JOHN T. BOYD COMPANY Figure 7.1 below illustrates the stripping bench and the sand bench from the rim of the pit. The operation has numerous dewatering pumps to maintain the working pit. The mine plan in Section 7.3.3 illustrates the yearly advancement of the pit. Figure 7.1: Utica Quarry Pit looking North 7.2 Mine Schedule, Equipment, and Staffing Currently the mine pit operates two, 10-hour shifts, four days per week resulting in a 40-hour work week per shift. A 10-hour Friday shift is added if needed. Generally, there are seven employees on the day shift and five employees on the night shift. Stripping is generally completed during the day shift and sand is hauled to the wet plant at night. Day shift primary equipment consists of: • Four 40T articulated haul trucks. • Three Various size front-end loaders. • One Deere 870 excavator. • One Grade • One Dozer.


 
7-3 JOHN T. BOYD COMPANY In addition, there are numerous support vehicles (maintenance trucks, skid steers, water truck, etc.) to complement the fleet. The mine, plants and loadout operate year around. The entire complex employs approximately 54 employees. 7.3 Mine Production 7.3.1 Historical Mine Production Utica predominantly produces 20/40-mesh, 30/50-mesh, 40/70-mesh and 70/140-mesh (100-mesh) frac sand products for sale to destinations served by predominantly the Burlington Northern Railway. The majority of the finished product is railed to the final destination after trucked and loaded onto rail at their nearby Peru, Illinois loadout facility. The sand is mined, processed, stored, and shipped from one contiguous property. Production from the operation commenced in mid-2012. Recent historic ROM production is as follows: Table 7.1: Historic ROM Production Year Finished Tons (000) 2019 n/a 2020* 722 2021 1,136 est * Acquired partial year 7.3.2 Forecasted Production Forecasted ROM sand production is estimated as follows: Table 7.2: Forecasted ROM Production Tons Year 2022 Year 2023 Year 2024 Year 2025 Year 2026 ROM Production tons (000) 982 982 982 982 982 The average process yield is reported to be 81.5%; as such, 982,000 ROM tons are expected to produce approximately 800,000 tons of finished product.


 
7-4 JOHN T. BOYD COMPANY 7.3.3 Expected Mine Life As of December 31, 2021, reserves for the Utica Mine are estimated at 129 million saleable tons. Projecting an average yearly sales volume of 800,000 tons per year, the operation has a LOM of approximately 161 years. Figure 7.2: Utica Proposed Mine Plan The illustration above depicts the proposed LOM plan for the Utica Mine. The LOM plan assumes a steady-state sales volume in the 800,000 product tons per year range for approximately 150 years through year 2172. Future mine plan production, and hence the longevity of the mine, is directly related to energy market demand for proppant sand. Actual yearly production volumes may, and are likely to, fluctuate significantly based on this demand. 7.3.4 Mining Risk Surface mines face two primary types of operational risks. The first category of risk includes those daily variations in physical mining conditions, mechanical failures, and


 
7-5 JOHN T. BOYD COMPANY operational activities that can temporarily disrupt production activities. Several examples are as follows: • Water accumulations/soft floor conditions. • Process water shortages. • Power curtailments. • Variations in grain size consistency. • Encountering excessive clay and other waste material. • Failures or breakdowns of operating equipment and supporting infrastructure. • Weather disruptions (power outages, dust storms, excessive heat etc.). The above conditions/circumstances can adversely affect production on any given day, but are not regarded as “risk issues” relative to the long-term operation of a mining entity. Instead, these are considered “nuisance items” that, while undesirable, are encountered on a periodic basis at many mining operations. BOYD does not regard the issues listed above as being material to the Utica Mine operations or otherwise compromising its forecasted performance. The second type of risk is categorized as “event risk.” Items in this category are rare but include significant occurrences that are confined to an individual mine, and ultimately have a pronounced impact on production activities and corresponding financial outcomes. Examples of event risks are major fires or explosions, floods, or unforeseen geological anomalies that disrupt extensive areas of proposed or operating mine workings and require alterations of mining plans. Such an event can result in the cessation of production activities for an undefined but extended period (measured in months, and perhaps years) and/or result in the sterilization of frac sand reserves. This type of risk is minimal in a relatively simple surface sand mining operation. q:\eng_wp\3555.021 - ss s-k 1300\wp\rpt\section ii - utica reserves\ch-7 - mining operations.docx


 
8-1 JOHN T. BOYD COMPANY 8.0 PROCESSING OPERATIONS 8.1 Overview The Utica plant area commenced wash plant operations in 2014. Initially, the work in process sand was railed to a dry process plant in Corpus Christi, Texas. In 2018, a 1.6 million tons per year dry process plant was constructed on site and is currently utilized. The ROM sand material is hauled to an in-pit feed hopper where it is slurried and pumped to an enclosed wet process plant. 8.1.1 Wet Plant Figure 8.1 below shows the enclosed wet plant where the material between 20-mesh and 140-mesh is classified and pumped onward to the dry process plant at the northeast end of the property. The waste < 140-mesh sand and oversize is hauled back into a mined out area of the pit. The wet plant employs typical screen/hydrosizer /cyclone classification and dewatering technology and also has an ultrafine circuit and thickener. The wet plant operates two, 10-hour shifts, four days per week. This schedule fluctuates based on product demand. The nominal capacity of the plant is approximately 450 tph of ROM sand. Figure 8.1: Utica Wet Processing Plant


 
8-2 JOHN T. BOYD COMPANY 8.1.2 Decant/Dry Plant The slurried WIP (20/140-mesh) material is pumped to an enclosed decant shed for dewatering prior to entering the dryer. A drag chain arrangement reclaims dryer sand from the top of the decant pile and conveys the sand to a 250 tph natural gas fired dryer. Dry sand is then screened into predominantly 20/40-mesh, 30/50-mesh,40/70-mesh, and 70/140-mesh (100-mesh) finished products. The finished products are stored in four 2,000-ton truck loadout silos. All product leaves the plant via truck. Several industrial customers truck the sand directly to their plants. The majority of the product is trucked to a nearby Peru, Illinois rail loadout servicing the Burlington Northern Railway. The dry plant operates 20 hours per day, four to five days per week. Approximately 54 people work at the Utica Facility. Figure 8.2: Decant Shed and Dry Processing Plant 8.2 Conclusion Based on our review of the Utica Mine, it is BOYD’s opinion that the processing methods and existing equipment at the plant will be sufficient for the planned production of frac sand. q:\eng_wp\3555.021 - ss s-k 1300\wp\rpt\section ii - utica reserves\ch-8 - processing operations.docx


 
9-1 JOHN T. BOYD COMPANY 9.0 MINE INFRASTRUCTURE The Utica Mine is serviced by three phase power that is routed along US highway 6, which runs north of the northern property line. The pipeline providing natural gas supply for the drying equipment is also routed along this corridor. Plant process water is supplied by water collected in the pit and ponds. Additionally, the wash process water is recycled after fines are removed via settling with a flocculent in a thickener and series of constructed ponds. As the mine progresses, silt ponds are constructed in mined-out areas. Wastewater from offices and other buildings are collected via a municipal sewer line. Potable water is provided by public water supply. On-site facilities include a scale house, office, shop, and a quality laboratory located in the dry process plant. The operation employs approximately 54 people and staffing varies based on production demand. The surface facilities currently located at the mine are well constructed and have the necessary capacity/capabilities to support the Utica Mine’s near-term operating plans. Operational preference may lead to the upgrading of some existing facilities if the operation expands in the future. q:\eng_wp\3555.021 - ss s-k 1300\wp\rpt\section ii - utica reserves\ch-9 - infrastructure.docx


 
10-1 JOHN T. BOYD COMPANY 10.0 MARKET ANALYSIS The frac sand market is driven by unconventional horizontal drilling in the oil and gas industry. In the late 1990s, rapid advances in horizontal drilling and hydraulic fracturing (fracking) in North America ushered in large-scale commercial oil and gas production. This fracking technique has been increasingly successful and modified over time to extract oil and gas held in dense layers of shale rocks, whose low permeability had previously prevented the flow of hydrocarbons. Hydraulic fracturing uses a mixture of water, chemicals, and proppant (natural sand or man-made sand-like substances) to fracture shale rock and release hydrocarbons such as oil, natural gas and natural gas liquids. The proppant acts to keep the fractures open (prop) while the pressurized fluids flow back up the well piping. Wells have become more productive with the addition of horizontal drilling capabilities, longer lateral lengths, and multi-stage fracks. North America’s shale oil industry’s growing competitiveness gained through continuous technology improvement and falling production costs have had major implications on the global energy market. Oilfield service companies, including frac sand producers, made significant cuts in 2020 to survive lower commodity prices because of the COVID-19 pandemic. Figure 10.1 illustrates the CME Group’s West Texas Intermediate (WTI) Crude Oil Annual Average Futures Price. We estimate breakeven pricing for unconventional oil wells in the Permian to be in the $30 to $40 per barrel range, with some areas in the mid $20s per barrel. 2021 WTI futures pricing showed a strong recovery following the 2020 COVID-19 impact. $30.00 $35.00 $40.00 $45.00 $50.00 $55.00 $60.00 $65.00 $70.00 $75.00 2021 2022 2023 2024 2025 2026 2027 2028 2029 2030 2031 2032 WTI Crude Oil CME Futures Price ($/bbl) Figure 10.1: WTI Crude Oil CME Futures Price


 
10-2 JOHN T. BOYD COMPANY Although Smart Sand’s market area is essentially all of the energy basins in the United States and western Canada, we have selectively focused on the Permian, Appalachian, and Denver-Joulesberg (DJ) as these are target markets for their frac sand. The Oakdale Mine has advantaged delivered cost to the western basins like the DJ as the Oakdale Mine directly loads onto the Canadian Pacific Railway, a very competitive option for westbound sand to the DJ. Oakdale also owns a loadout near the mine which enables them to load directly on the Union Pacific Railway, the favored Permian basin rail. The Utica Mine has access to their nearby Burlington Northern rail loadout which greatly complements the Oakdale facility, especially when moving product to the Appalachian (Marcellus-Utica) basin. Therefore, a high-level overview of demand in these basins follows. 10.1 Permian Basin Permit submissions for horizontal oil and gas wells in the Permian indicate a continuation of strong drilling ahead. According to InfillThinking, the number of permits filed per working rig this summer is tracking at multi-year highs as evidenced in Figure 10.2 below. Figure 10.2: Permian Basin HZ Permit Submissions vs. Rigs


 
10-3 JOHN T. BOYD COMPANY Over the previous 52 weeks, rig counts in the Permian are up approximately 111%. This has led to increased production for both crude oil and natural gas. For the same time period, crude oil (barrels per day) and natural gas production (thousand cubic feet per day) in the Permian are up 10% and 9%, respectively. As Figure 10.3 illustrates, Permian daily crude oil production is nearing its pre-pandemic impacted peak, while daily natural gas production in the Permian continues to make new records and now stands at 18.6 billion cubic feet per day. Figure 10.3: Permian Oil Production and Natural Gas Production According to U.S. Energy Information Administration Drilling Productivity Report, drilled but uncompleted wells (DUCs) in the Permian Basin have declined 43% since peaking in July 2020 (refer to Figure 10.4). These data dovetail with increased crude oil and natural gas production in the basin. Figure 10.4: Permian Drilled but Uncompleted Wells - 1,000,000 2,000,000 3,000,000 4,000,000 5,000,000 6,000,000 Ja n- 19 Fe b- 19 M ar -1 9 Ap r- 19 M ay -1 9 Ju n- 19 Ju l-1 9 Au g- 19 Se p- 19 O ct -1 9 N ov -1 9 De c- 19 Ja n- 20 Fe b- 20 M ar -2 0 Ap r- 20 M ay -2 0 Ju n- 20 Ju l-2 0 Au g- 20 Se p- 20 O ct -2 0 N ov -2 0 De c- 20 Ja n- 21 Fe b- 21 M ar -2 1 Ap r- 21 M ay -2 1 Ju n- 21 Ju l-2 1 Au g- 21 Permian Oil Production (bbl/d) - 2,000,000 4,000,000 6,000,000 8,000,000 10,000,000 12,000,000 14,000,000 16,000,000 18,000,000 20,000,000 Ja n- 19 Fe b- 19 M ar -1 9 Ap r- 19 M ay -1 9 Ju n- 19 Ju l-1 9 Au g- 19 Se p- 19 O ct -1 9 N ov -1 9 De c- 19 Ja n- 20 Fe b- 20 M ar -2 0 Ap r- 20 M ay -2 0 Ju n- 20 Ju l-2 0 Au g- 20 Se p- 20 O ct -2 0 N ov -2 0 De c- 20 Ja n- 21 Fe b- 21 M ar -2 1 Ap r- 21 M ay -2 1 Ju n- 21 Ju l-2 1 Au g- 21 Permian Natural Gas Production (Mcf/d) - 500 1,000 1,500 2,000 2,500 3,000 3,500 4,000 Ja n- 19 Fe b- 19 M ar -1 9 Ap r- 19 M ay -1 9 Ju n- 19 Ju l-1 9 Au g- 19 Se p- 19 O ct -1 9 N ov -1 9 De c- 19 Ja n- 20 Fe b- 20 M ar -2 0 Ap r- 20 M ay -2 0 Ju n- 20 Ju l-2 0 Au g- 20 Se p- 20 O ct -2 0 N ov -2 0 De c- 20 Ja n- 21 Fe b- 21 M ar -2 1 Ap r- 21 M ay -2 1 Ju n- 21 Ju l-2 1 Au g- 21 Permian Drilled but Uncompleted Wells


 
10-4 JOHN T. BOYD COMPANY Although a majority of this large basin’s sand is sourced from local sand mines, Northern White, Oakdale quality sand remains an important product for many well applications. 10.2 Appalachian Basin (Marcellus/Utica Play) and Niobrara Basin Although smaller in size than the Permian energy fields, the Appalachian and Nioobrara (DJ) are substantial natural gas and oil plays in North America. Unlike the Permian, the Appalachian and Niobrara import the vast majority of the frac sand. Very few notable in-basin sand operations exist. This creates an advantaged situation for the Oakdale and Utica mines as they are advantaged, transport wise to the basin and there are few substitutes for NWS. Following the energy downturn in 2019 and then Covid shutdown in 2020, the basin wellfield activity appears to be rebounding. Horizontal rigs have stabilized over the past two years as can be seen on Figure 10.5, but gas production per rig is substantially higher. Energy companies are drilling longer laterals and optimizing each well pad becoming more efficient from a cost perspective and overall natural gas production is stable as can be seen from Figure 10.6. Figure 10.5: Appalachian Rig Count and Production per Rig (Source: EIA)


 
10-5 JOHN T. BOYD COMPANY Figure 10.6: Appalachian Gas Production (Source: EIA) Similarly, the DJ basin has seen a rebound in rig count since the Covid shutdown. Both gas and oil rig counts have risen but productivity per well has decreased as can be seen in Figure 10.7. Figure 10.7: Niobrara Oil and Gas Rig Count and Productivity (Source: EIA)


 
10-6 JOHN T. BOYD COMPANY Overall gas and oil production remains relatively flat in the basin, but more wells are being drilled to maintain this capacity. Figure 10.8 illustrates the overall yearly gas and oil production in the basin. Figure 10.8: Niobrara Oil and Gas Production (Source: EIA) Having survived the challenging environment of 2019 and 2020, Smart Sand’s operations should continue to prove viable into the future notwithstanding a sustained and significant energy price collapse. Their low-cost mining scheme, advantaged transport to select basins, and high-quality product help to create an advantage compared with other NWS producers.

12-1 JOHN T. BOYD COMPANY 12.0 ECONOMIC ANALYSIS 12.1 Introduction Cash flow projections for the Utica operation have been generated from the proposed LOM production schedules, revenues, cost of goods sold (COGS), and CapEx estimates discussed in Chapter 11. A summary of the key assumptions used is provided below. • LOM ROM frac sand tons and product tons sold were based on the total frac sand reserve estimates discussed in Chapter 6 of this report. BOYD estimates that the Utica operation reserves would be depleted in Year 2182. • Forecasted revenues at the Peru off-site loadout (mine gate) are based on sales of 20/40, 30/50, 40/70, and 70/100-mesh size products to be delivered to its customer base in the various energy basins via the BNSF railway or other connecting rail carriers. • Operating and Other Costs (as discussed in Chapter 11) include: − Employee wages, and benefits. − Excavation. − Utilities. − Equipment. − Maintenance. − Peru Trucking Costs. − Real Estate Taxes. − Other Operating Expenses. − SG&A. • Reclamation costs include: − Final reclamation cost to reclaim the Utica operation/sites. • Capital Expenditures (as discussed in Chapter 11) include: − Sustaining/Maintenance. • Taxes are based on: − Federal Business Income Tax Rate of 21%. − Illinois Corporate Income and Replacement Tax Rate of 9.5% (reduced to 7.3% after Year 2024). • Adjustments used to determine After-Tax cash flows: − Current depreciation expense was provided by Smart Sand for the Utica operation.


 
12-2 JOHN T. BOYD COMPANY − Depreciation expense, for new fixed assets (from sustaining/maintenance CapEx), is based on a straight-line depreciation calculation using a 10-year asset life. − Operating losses, if any, are carried forward in the tax computation. 12.2 Economic Analysis BOYD prepared an economic analysis, as of January 1, 2022, for the Utica Operation using the production, sales, and financial projections presented in this report. Our analysis confirms that the operation generates positive cash flows (based on a 12% discount rate), on a pre-tax and after-tax basis, that supports the statement of frac sand reserves herein. 12.2.1 Cash Flow Analysis Table 12.1 below presents the pre-tax and after-tax cash flow projections based on the proposed LOM production schedule, revenue, COGS, CapEx and other estimates discussed above for the Utica operation.

The DCF-NPV values used mid-year discounting and all cash flows were on a constant dollar basis.


 
12-3 JOHN T. BOYD COMPANY The pre-tax DCF-NPV ranges from approximately $19.5 million to $28.5 million. The after-tax DCF-NPV ranges from approximately $16.8 million to $23.8 million. Table 12.2 summarizes the results of the pre-tax and after-tax DCF-NPV analyses: DCF-NPV ($ 000) 10% 12% 15% Pre-Tax 28,531 24,013 19,483 After-Tax 23,797 20,347 16,824 Table 12.2: DCF-NPV Refer to Table 12.3 on the next page for the detailed LOM cash flow analysis and corresponding pre-tax and after-tax DCF-NPV analyses at a 12% discount rate. BOYD notes that the NPV estimate was made for purposes of confirming the economic viability of the reported frac sand reserves and not for purposes of valuing Smart Sand, the Utica operation, or its assets. IRR and project payback were not calculated, as there was no initial investment considered in the financial model. Risk is subjective, as such, BOYD recommends that each reader should evaluate the project based on their own investment criteria. 12.2.2 Sensitivity Analyses Sensitivity analyses for the pre-tax and after-tax cash flows considering changes to revenues and COGS/CapEx were prepared using discount rates of 10%, 12%, and 15%. Revenues were adjusted in increments of 5% and range from minus 20% to plus 20% of base revenues; the corresponding weighted average sales price would range from $16.00 per ton sold to $24.00 per ton sold, with the base price of $20.00 per ton sold as noted in Table 12.4 below.

13-1 JOHN T. BOYD COMPANY 13.0 PERMITTING AND COMPLIANCE 13.1 Permitting The Illinois Department of Natural Resources (IDNR) requires a Surface Mining Permit for all operations that affect over 10 acres per year by mining or remove more than 10 ft of overburden (soil on top of the rock or mineral being extracted). A Surface Mining Permit application requires the operator to submit an operating plan that illustrates how the land will be affected by mining operations as well as a reclamation plan that describes how the mined land will be restored for future use. The mine reclamation plan must be submitted for review to the LaSalle County Board. If the County Board requests, a public hearing will be scheduled by the IDNR to receive comments on the proposed reclamation plan. The Utica operation has a current IDNR permit. Air emissions at the Utica facility are regulated by the Illinois Environmental Protection Agency. A Title V permit for air emissions is currently issued to Northern White Sand Company (Permit # 170090027), the company that filed the permit application prior to Smart Sand’s acquisition. 13.2 Compliance Mine safety is regulated by the federal government by MSHA as are all surface mining operations. MSHA inspects the facilities a minimum of twice yearly. Smart Sand’s safety record compares favorably with its regional peers. Based on our review of information provided by Smart Sand and available public information, it is BOYD’s opinion that the Utica Mine’s record of compliance with applicable mining, water quality, and environmental regulations is generally typical for that of the industry. BOYD is not aware of any regulatory violation or compliance issue which would materially impact the frac sand reserve estimate. q:\eng_wp\3555.021 - ss s-k 1300\wp\rpt\section ii - utica reserves\ch-13 - permitting and compliance.docx


 
14-1 JOHN T. BOYD COMPANY 14.0 INTERPRETATION AND CONCLUSIONS 14.1 Findings Based on our independent technical review and geoscientific study of the Utica Mine, BOYD concludes: • Sufficient data have been obtained through the site exploration and sampling program and mining operations to support the geological interpretations of seam thickness, grain size distribution and API quality for the portions of the sand underlying the controlled property. The data are of sufficient quantity and reliability to reasonably support the sand resource and sand reserve estimates in this technical report summary. • Estimates of proppant sand reserves reported herein are reasonably and appropriately supported by technical studies, which consider mining plans, revenue, and operating and capital cost estimates. • The 128.8 million product tons of frac sand reserves (as of December 31, 2021) identified on the property are economically extractable under reasonable expectations of market volumes and pricing for proppant sand products, estimated operation costs, and capital expenditures. • There is no other relevant data or information material to the Utica Mine that is necessary to make this technical report summary not misleading. 14.2 Significant Risks and Uncertainties As with any mining project there are certain inherent risks associated with the overall operation of a facility. Smart Sand has sufficiently mitigated operational risk through obtaining sufficient geologic sampling information and analysis. Additionally, Smart Sand has engineered the processing plant to include parallel duplicate process circuits which significantly increases plant availability. However, it should be noted that frac sand is generally marketed exclusively to the energy industry which has historically been a volatile industry. q:\eng_wp\3555.021 - ss s-k 1300\wp\rpt\section ii - utica reserves\ch-14 - conclusions.docx
