About Cascadia Minerals Ltd.

Cascadia'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 35 kilometres 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 million pounds of copper and 302,000 ounces of gold (36.3 million tonnes grading 0.81 per cent copper, 0.26 gram per tonne gold, and 3.23 g/t silver and 0.01 per cent molybdenum) with a 2023 PEA (preliminary economic assessment) demonstrating positive economic potential ($230.5-million posttax NPV (net present value) (5-per-cent discount rate) and 29-per-cent posttax IRR (internal rate of return).

Cascadia also has a pipeline of discovery stage copper-gold properties throughout the Yukon Stikine terrane including its Catch property, which hosts a copper-gold porphyry discovery where inaugural drill results returned broad intervals of mineralization (116.60 m of 0.31 per cent copper with 0.30 g/t gold). Catch exhibits extensive high-grade copper and gold mineralization across a five km long trend, with rock samples returning peak values of 3.88 per cent copper, 1,065 g/t gold and 267 g/t silver.
