About Cascadia
Cascadia is a Canadian junior mining company focused on making new copper and gold discoveries the Yukon and British Columbia.

Catch exhibits extensive high-grade copper and gold mineralization across a 5 km long trend, with rock samples returning peak values of 3.88% copper, 1,065 g/t gold, and 267 g/t silver.

Granite Creek's flagship asset is the Carmacks Project in the high-grade Minto copper district in Yukon Territory, Canada. The project is located south of and within 35km of the past-producing Minto mine, which was recently acquired by Selkirk Copper Mines. The Carmacks Project hosts a Measured and Indicated Resource containing 651 Mlbs of copper and 302 koz of gold (36.3 million tonnes grading 0.81 % copper, 0.26 g/t gold, and 3.23 g/t silver and 0.01% molybdenum) with a 2023 PEA demonstrating positive economic potential ($230.5 M Post-Tax NPV_(5%) and 29% Post-Tax IRR).

The Mineral Resources disclosed here are referenced from the 2023 Technical Report on the Carmacks Project Preliminary Economic Assessment, authored by SGS Canada Inc. for Granite Creek Copper, and have not been independently reviewed by Cascadia. Pricing for the Carmacks Project PEA base case economic analysis was US $3.75/lb copper, US $1,800/oz gold, and US $22/oz silver at an exchange rate of $1:US$0.75. For more details on the economic analysis, refer to the 2023 Technical Report on the Carmacks Project Preliminary Economic Assessment, authored by SGS Canada Inc. for Granite Creek Copper. The results of the Carmacks preliminary economic assessment are preliminary in nature, it includes inferred mineral resources that are considered too speculative geologically to have the economic considerations applied to them that would enable them to be categorized as mineral reserves, and there is no certainty that the preliminary economic assessment will be realized.
