Notes to the Resource Estimate Tables:
- The Mineral Resource Estimates was completed by Sue Bird, P.Eng. who is independent of the Company, with an effective date of November 6, 2025.
- The Mineral Resource Estimate for all four deposits have been confined by an open pit with “reasonable prospects of eventual economic extraction” using the following assumptions:
- Metal price of US$2,600/oz Au; /Payable metal of 99% for Au; /Offsite costs (TC/RC/Transport) for Au of US$5.80/oz;
- Pit slopes are 45 degrees; /Mining cost of mineralized material of CDN$2.56/t and CDN$2.40/t for waste, and;
- Processing costs of CDN$15.60/t with G&A costs of CDN$7.20/t. / Metallurgical recoveries are 90% for all deposits.
- Forex = 0.72 $US:$CDN /The NSR equation is: NSR (CDN$/t) = (Au*90%*CDN$114.68/g)
- The specific gravity for each deposit and lithologies or domains ranges from 2.40 to 2.91.
- Numbers may not add due to rounding.
The Preview SW Deposit is located approximately 75 km northeast of La Ronge and is accessible via Highway 102 and a maintained local trail. It spans three dispositions covering 843 hectares.
Infrastructure: Powerlines are nearby, extending from the Contact Lake Deposit. The community of Missinipi is located about 30 km north of the deposit.
Recent Drill Programs: Recent drill programs in 2017, 2018 and 2022 tested the continuity of gold mineralization along strike and down-dip in addition to discovering new gold zones and expanding the historical mineral resource. The Preview SW Deposit offers significant growth and discovery potential.
Deposit Information:
- First staked in 1937 and subsequently acquired by Preview Mines Ltd. in 1938 (Livingstone & Christian, 2017).
- Ownership evolved through Studer Mines Ltd., Westfield Minerals Ltd., and Cameco Corporation (1979-2004).
- La Ronge Gold Corp. (later Select Sands Corp.) acquired the property in 2011, releasing a resource estimate in 2012.
- Comstock Metals Ltd. acquired the Preview SW claims in 2016, releasing an updated resource estimate.
- MAS Gold Corp. reached an agreement to acquire the claims in 2022, with the sale finalized in March 2022.
Key Deposit Features:
- Multiple sub-parallel, northeast-trending shear zones (1-10 m wide) host auriferous quartz veins that are persistent at depth. Dilatant structures within these shear zones are directly related to gold mineralization (Simpson, 2016).
- Gold mineralization is associated with various sulfides including arsenopyrite, pyrite, and pyrrhotite.
