Mineral Resources
The mineral resource update benefited from the results of the 93-drillhole program (1,574 metres; vertical -90º holes with true width intersections), which was managed, logged and sampled by APEX Geoscience Ltd. A total of 761 samples were collected including 237 LBI, 57 UBI, 17 BS and 450 Pgf samples. All 761 samples were analyzed for particle grainsize distribution analysis using a Camsizer P4 Particle analyzer. A subset of 675 grain size fractions were analyzed for proppant characterization test work including Krumbein shape factor and crush resistance. An additional 14 samples underwent complete proppant test work that included acid solubility and turbidity (in addition to Krumbein shape factors and crush resistance test work). A split of 58 samples were collected and analyzed for loose-sand bulk density analysis.
Quality Assurance – Quality Control samples were collected and analyzed to test the precision and accuracy of duplicate sample pairs for both gradation measurements and crush resistance tests (and at multiple labs).
The analytical work was completed at Turnkey Processing Solutions in Ottawa, IL and Stim-Lab in Duncan, OK. The analytical work was carried out by independent, accredited laboratories. The analytical methods are standard and routine in the field of silica sand, or proppant, test work pursuant to International Organization for Standardization 13503-2.
The mineral resources within the Wanipigow Property has been classified as Measured, Indicated and Inferred Resources in accordance with NI 43-101, and has been estimated using the CIM Estimation of Mineral Resources and Mineral Reserves Best Practice Guidelines (2003) and the CIM “Definition Standards for Mineral Resources and Mineral Reserves (2014). Several factors were considered for the Mineral Resource classification including: drillhole spacing; nature of the geological contacts; the degree of testing; proppant quality, and lateral and vertical continuity. These factors serve as a proxy for geological confidence and the level of uncertainty of the individual units.
The 3-D geological model is defined by 93 vertical drillholes completed by CPS in 2018. The gradation data form an assay file that was used to calculate the Wanipigow Property Silica Sand Resource Estimate. The resource is calculated using a block model with a size of 20 by 20 m in the horizontal directions and 2 m in the vertical direction. The Wanipigow estimation of the individual sieve size fractions was completed and reported using a lower cutoff of mesh-sizes that are greater to or equal to 20-mesh and less than or equal to 140-mesh fraction. The loose bulk densities were converted to in-situ compacted bulk densities using a bulking factor of 30% and include: Pgf: 1.90 g/cm3; UBI: 1.91 g/cm3; LBI: 1.88 g/cm3. Bulk densities were utilized to convert volume (cubic metres) to tonnages.
Mineral resources are not mineral reserves and do not have demonstrated economic viability. This Wanipigow Property Silica Sand Resource Estimate predicts total (i.e., global) resources of:
-
• | Lower Black Island Measured & Indicated Resources of 45.1 million tonnes; |
-
• | Upper Black Island Indicated Resource of 4.4 million tonnes and Inferred Resource of 1.7 million tonnes; and |
-
• | Pleistocene glaciofluvial Inferred Resource of 95.6 million tonnes (Tables 1 and 2). |
Mineral Reserves
The Mineral Resources were converted to Mineral Reserves through the application of the appropriate Modifying Factors to potential mining volumes created during the mine design and planning process. In this PFS, a Mineral Reserve is defined as the Measured and Indicated Mineral Resource that would be extracted by the mine design and which can then be processed and sold at a profit. Inferred Resources were not converted to Mineral Reserves. The Measured resources meeting that standard were classified as Proven mineral reserves, while the Indicated resources meeting that standard were classified as Probable mineral reserves.
To derive the estimate of the saleable product tons, or Mineral Reserves: no external dilution was applied; internal dilution consisted of the +20 and -140 size fractions as interpolated in the Mineral Resource block model; mining losses of 5% represent Mineral Resources not extracted due to operational constraints encountered during routine mining operations; and processing losses of 5% due to general inefficiencies in the processing of silica sand.
The Mineral Reserve complies with CIM definitions and is supported by a detailed mine plan and cash flow model. The Mineral Reserves estimated for the Wanipigow Silica Sand Project are subject to the types of risks common to most silica sand quarry operations that exist in Canada. These risks include but are not limited to: site-specific mining and geological conditions, management and personnel capabilities, availability of funding to properly operate and capitalise the operation, variations in cost elements and market conditions, developing and operating the mine in an efficient manner, unforeseen changes in legislation and new industry developments. There is no guarantee that all or any part of the estimated Mineral Resource or Mineral Reserve will be recoverable.
The mineral reserves, expressed as saleable product tonnages, estimates Proven & Probable reserves of: 26.8 million tonnes of LBI; and 3.8 million tonnes of UBI (Table 3).
Mining Method
The Wanipigow Silica Sand Project is projected to include a conventional, open pit quarry employing typical truck-and-excavator mining operations. The quarry and fully enclosed plant are planned to operate 24 hours per day, 7 days per week year-round (weather permitting) and are expected to extract approximately 1.8 million tonnes of raw sand per year at full production. At this mining rate, the operation will produce an average of 1.2 million product tonnes per year after processing losses. The mine life is projected to be at least 26 years after which an estimated 43.2 million tonnes of raw sand and 11.6 million bank cubic metres of waste materials will have been mined.

Capital Costs
Capital expenditure estimates were provided by TPS and developed by using first principles and applying direct project experience. The estimates were reviewed by the qualified persons and found to be reasonable and appropriate for a Preliminary Feasibility Study. The accuracy of the capital expenditure estimate is +/-10% and includes initial, sustaining and total Capital Cost estimations. Salvage value was not considered in the PFS.
The capital expenditure estimate for the CPS wet and dry plant, loadout and related infrastructure is approximately CDN$220 million, including a contingency of approximately CDN$16 million. Additionally, the company expects to lease mobile equipment to minimize upfront expenditures. Mobile equipment lease payments are estimated to total approximately CDN$90 million over the life of the mine (“LOM”). A further CDN$20 to CDN$25 million are contemplated for miscellaneous development and rebuilds for sustaining capital expenditures over the LOM. As a result, the total capital expenditure and leaserelated costs are estimated at CDN$330 to CDN$335 million for LOM plan.
Sustaining capital expenditures are incurred to maintain production and expected to be in the range of CDN$0.75 per tonne, or CDN$20 to CDN$25 million over LOM. Exclusions from the capital expenditures estimate include, but are not limited to, project financing and interest charges and working capital.
Operating Costs
Operating cost estimates were provided by TPS. These were reviewed by the qualified persons and found to be reasonable and appropriate for a Preliminary Feasibility Study. A summary of the first five years of operating costs is presented in Table 4.

About Canadian Premium Sand Inc.
The Preliminary Feasibility Report is the culmination of a 9-month program initiated by the Company in 2018 which focused on the completion of a 93 sonic drill hole exploration program completed by Boart Longyear of Calgary with independent oversight by APEX including 1,574 meters of core within its 42 Quarry Leases encompassing 2,289 hectares. Laboratory testing was conducted on 761 samples by Stim-Lab and TPS to estimate the potential product quality of the silica sand reserves and to allow development of a mine plan and conduct the engineering to develop a detailed plant flowsheet. In addition, a market study was completed and the necessary infrastructure improvements were identified to support the entire facility.
Simultaneously with this program, the Company began the permitting and licensing process to obtain all necessary approvals from Hollow Water First Nation, the local community of Seymourville and the province of Manitoba. All of these approvals have been granted including a confirmation from the Canadian Minister of Environment and Climate Change that the project would not be designated for environmental assessment under CEAA 2012.
