Canadian Premium Sand Inc. Announces Substantial Increase in Low-Iron Sand Resource
Canadian Premium Sand Inc. Announces Substantial Increase in Low-Iron
Sand Resource
CALGARY, Alberta, April 09, 2025 -- Canadian Premium Sand Inc. (“CPS” or the “Company”) (TSXV: CPS) is pleased to
announce an updated Inferred Mineral Resource Report (the “2025 Technical Report ”) has been completed for the Company’s
Wanipigow Sand Project (the “Sand Project ”) by APEX Geoscience Ltd., with an effective date of April 09, 2025. The 2025
Technical Report incorporates the results of additional sampling, processing and testing along with glass melt testing made
possible through core programs and bulk excavation completed by the Company between 2022 and 2024.
The Sand Project proposes to supply the Company’s planned future pattern solar glass manufacturing facilities in Selkirk,
Manitoba and in the US.
Key highlights of the 2025 Technical Report:
• The Company extended its Lower Black Island Member sand processing test work to achieve low-iron sand to other
portions of the Sand Project property.
• The Company received positive results from its mineral processing tests conducted between 2022 and 2024 that
include beneficiation studies, glass melt tests and an anti-reflective solar glass coating test.
• The resulting Lower Black Island glass sand mineral resource estimate in the 2025 Technical Report is 3.4 times larger
than the resource reported in the Company’s initial LBI glass sand resource (dated October 14, 2021).
Table 1: The Wanipigow Glass Silica Sand Inferred Resource Estimate reported for the Lower Black Island sand as a total
(global) volume and tonnage. The Total In-Situ values in grey represent the main inferred mineral resource estimate. A
breakdown of the individual resource areas is also presented. Mineral resources are not mineral reserves and do not have
demonstrated economic viability.

Note: 1: The ‘Total in-situ’ (global) volume and weights are estimated on a global basis and represent the main Inferred Wanipigow Glass Sand Resource Estimate.
Note: 2: A nominal in-situ, or compacted, sand bulk density of 1.877 g/cm3 was applied to the Lower Black Island sand unit
Note 3: The resource estimation of utilized cutoff of mesh-sizes that are greater than or equal to 35-mesh (<500 µm) and less than or equal to 120-mesh (<125 µm). The +35
and -120 mesh size fractions were discarded from the estimation process
The justification of the increase in mineral resource areas is based on the positive results of the Company’s 2022 to 2024
mineral processing tests that include beneficiation studies, melt glass tests, and an anti-reflective solar glass coating test.
During this period, CPS extended its Lower Black Island Member sand processing test work to other portions of the Sand
Project property and continued to improve the beneficiation process. The expanded resource areas include those areas where
the Lower Black Island sand successfully beneficiated to low-iron (≤100 ppm Fe 2O3 LBI sand).
The updated Lower Black Island glass sand resource estimate is constrained to 7 separate resource areas, encompassing a
total area of 5.18 km 2, where beneficiation testing achieved low-iron sand with ≤100 ppm Fe 2O3. Collectively, the 7 resource
areas encompass a surface area of 2.06 km2.
Of the 110 drillholes and 761 gradation measurements that define the Sand Project geological model, the mineral resource
areas collectively comprise 35 drillholes and 161 Lower Black Island gradation results. The combined resource areas have a
minimum and maximum Lower Black Island thicknesses of between 0.04 and 16.5 m with an average normalized thickness of
9.4 m.
The sedimentary material overlying the Lower Black Island unit was also modelled within a single wireframe denoted as waste
material. The overlying waste material is ubiquitous throughout the Wanipigow glass sand resource areas and extends from
the surface to depths of between 0.7 and 15.1 m and averages 8.7 m.
The glass sand mineral resource is calculated using a block model with a size of 20 by 20 m in the horizontal direction and 2
m in the vertical direction. The block model was used to calculate the Wanipigow glass sand resource estimate of the different
percentages of silica sand retained on the various screen sizes. Ordinary Kriging was used to estimate the size fraction values
at each parent block that lies within the Lower Black Island sand wireframe.
The resource estimation of the individual Lower Black Island size fractions was completed and reported using a lower cutoff of
mesh-sizes that are greater than or equal to 35-mesh (<500 µm) and less than or equal to 120-mesh (<125 µm). The +35 and -
120 mesh size fractions were discarded from the estimation process.
A nominal in-situ, or compacted, sand bulk density of 1.877 g/cm 3 was applied to the Lower Black Island sand unit. The
density is based on 36 representative loose bulk Lower Black Island density samples and the loose bulk densities were
converted to an in-situ bulk density by using a bulking factor of 30%. The overlying waste material has a compacted bulk
density of 1.902 g/cm 3.
The Wanipigow glass sand resource estimate has been classified and prepared in accordance with the Canadian Institute of
Mining, Metallurgy, and Petroleum definition standards and best practice guidelines (2014, 2019) and the disclosure rule
National Instrument 43-101. The Effective Date of the mineral resource estimate is 9 April 2025.
The inferred Wanipigow glass sand resource estimate predicts a total (i.e., global) Lower Black Island glass sand inferred
resource of 24.386 million metric tonnes (Table 1).
Mineral resources are not mineral reserves and do not have demonstrated economic viability. The estimate of mineral
resources may be materially affected by geology, environment, permitting, legal, title, taxation, socio-political, marketing, or
other relevant issues.
With respect to Lower Black Island sand tonnages within the individual mineral resource areas, Resource Area 2 has the
highest tonnage (11.229 million metric tonnes), followed by Resource Area 1 (8.668 million metric tonnes), Resource Area 4
(2.499 million metric tonnes), Resource Area 3 (1.030 million metric tonnes), and Resource Areas 5, 6, and 7 have between
238,000 and 436,000 tonnes.
Table 1 above highlights the increase in inferred mineral resource estimates expressed in metric tonnes as compared to the
previous Technical Report disclosed by the Company on October 14, 2021.
With respect to the overlying waste sedimentary rock and using a compacted bulk density of 1.902 g/cm 3, the combined
waste material contains an estimated 34.002 million metric tonnes.
Ongoing Lower Black Island sand beneficiation, furnace batch recipes, and glass chemical composition and physical
characteristics test work is required to assess and advance the quality of the sand to higher levels of glass manufacturing
standards in concert with CPS’s Modifying Factor studies.
