Cascadia Drills 82.69 m of 1.12% Cu and 0.64 g/t Au (1.78% CuEq) at the Carmacks Project, Yukon

Cascadia Minerals Ltd. (CAM) has released assay results for five additional holes drilled in 2026 at its Carmacks copper-gold project in the Yukon. The company reports that sulphide mineralization has now been encountered 300 meters beyond the existing Mineral Resource, effectively doubling the strike length of Zone 2000S.

Headline hole CD-26-056, located in Zone 2000S, returned 82.69 meters at 1.12% copper and 0.64 grams per tonne gold from a depth of 321.17 meters, reported as 1.78% copper equivalent. This interval includes a higher-grade sub-interval of 49.16 meters at 1.63% copper and 0.95 grams per tonne gold, reported as 2.62% copper equivalent.

Other results from the current program include:

• CD-26-054, Zone 2000S: 76.31 meters at 0.48% copper and 0.23 grams per tonne gold, including 12.56 meters at 0.73% copper and 0.48 grams per tonne gold.
• CD-26-052, Zone 147: 38.32 meters at 0.42% copper and 0.10 grams per tonne gold.
• CD-26-055, Zone 147: No significant results; the company states this suggests Zone 147 may be pinching out at depth in that direction.
• CD-26-053, Sourtoe target: No significant copper-bearing mineralization.

The 2026 drilling program has been expanded from 15,000 meters to 18,000 meters. To date, 26 holes have been completed for a total of 13,106 meters, with assays pending for six further Zone 2000S step-out holes.

Cascadia Minerals Ltd. (CAM) is a resource-stage developer and explorer with a market capitalization of approximately C$75 million. The company’s small equity base means that a meaningful resource expansion has the potential to move the share price.

The latest drilling result represents a major step-out, extending Zone 2000S 300 meters beyond the existing Mineral Resource boundary while delivering higher copper and gold grades than the current resource average. The prior anchor result was CD-26-050, reported on August 10, 2026, which returned 52.84 meters at 1.04% Cu and 0.37 g/t Au, or approximately 54.9 %-m Cu and 19.6 gram-metres of gold.

In comparison, CD-26-056 is materially stronger, returning approximately 92.6 %-m Cu and 52.9 gram-metres of gold, with a large high-grade core. This result represents a positive delta versus the prior anchor, rather than an in-line repeat.

The stock had risen from about C$0.30 in early July to C$0.36 by late August, but it had not re-rated dramatically on the earlier 2026 holes. The market had not fully embedded a hole of this tenor; therefore, the delta is genuinely new and unpriced.

However, the extension is not yet a confirmed deposit-scale transformation. It remains one exceptional hole, with six pending assays and some failed step-outs elsewhere. On balance, this is a material positive result for a sub-C$100 million copper-gold developer with an existing PEA and a clear resource-growth thesis.

Cascadia Minerals Ltd. is a Yukon-focused copper-gold explorer and developer. Its flagship asset is the 100%-owned, road-accessible Carmacks copper-gold project, located in the Minto Copper Belt of central Yukon. The project’s infrastructure includes a 13 km access road, a 40-person camp, and grid power located approximately 10 km away.

The Carmacks property hosts a measured and indicated resource of 36.3 million tonnes at 0.81% copper, 0.26 g/t gold, 3.23 g/t silver, and 0.01% molybdenum, containing 651 million pounds of copper and 302,000 ounces of gold. An inferred resource of 2.9 million tonnes at 0.60% copper and 0.16 g/t gold contains 38 million pounds of copper and 13,000 ounces of gold.

A 2023 preliminary economic assessment calculated a post-tax net present value of US$230.4 million and a 29% internal rate of return at US$3.75/lb copper and US$1,800/oz gold. A higher-case scenario yielded a net present value of US$330.1 million and a 38% internal rate of return at US$4.25/lb copper and US$2,000/oz gold.

The company’s regional portfolio includes the Catch, Macks, Milner, Byng, Mars, Rosy, and Idaho Creek projects. Agnico Eagle holds the right to earn up to 80% of Catch by funding up to C$30 million. Agnico Eagle also owns approximately 14.17% of Cascadia on a non-diluted basis as of April 2026, under an investor rights agreement that includes board nomination rights and a right of first offer on Carmacks.
