CASCADIA ANNOUNCES C$4.1M NON-BROKERED PRIVATE PLACEMENT

Cascadia Minerals Ltd. has arranged a non-brokered private placement of up to $4,106,667, led by strategic investor Michael Gentile, one of Cascadia's largest shareholders.

The offering will consist of the sale of: (a) 6,666,667 non-flow-through (NFT) units to be sold at a price of 15 cents per NFT unit, for total gross proceeds of approximately $1-million; and (b) 13,333,333 critical minerals flow-through (CFT) units to be sold at a price of 23.3 cents per CFT unit, for total gross proceeds of approximately $3,106,667.

"With the success of our initial resource expansion drill campaign at the Carmacks property this fall, we will be undertaking a significantly expanded work program next year," stated Graham Downs, Cascadia's president and chief executive officer, "This financing will fully fund a planned 15,000-metre diamond drilling program in 2026, which will continue to test expansion of the core Carmacks deposit, as well as evaluate numerous compelling regional targets. In addition, results from a further eight resource expansion holes drilled this fall are still outstanding, seven of which encountered sulphide mineralization."

Each NFT unit will comprise one common share and one-half of one common share purchase warrant. Each whole warrant shall be exercisable into one additional common share for 36 months from closing at an exercise price of 20 cents per warrant. Each CFT unit will comprise one flow-through common share and one-half of a warrant.

Each CFT share will qualify as a flow-through share within the meaning of Subsection 66(15) of the Income Tax Act (Canada). The gross proceeds from the issuance and sale of the CFT shares will be used for Canadian exploration expenses that qualify as flow-through critical mineral mining expenditures, as both terms are defined in the tax act. The qualifying expenditures will be incurred on or before Dec. 31, 2026, and will be renounced to the subscribers with an effective date no later than Dec. 31, 2025, in an aggregate amount not less than the gross proceeds raised from the issuance of the CFT shares.

The proceeds from the offering will be used for critical minerals exploration primarily at the Carmacks property. A portion of proceeds from the offering may be used for exploration at Cascadia's Catch, Macks, Milner and Idaho Creek properties.

The offering is scheduled to close on or before Dec. 22, 2025, and is subject to regulatory acceptance.

Finders' fees may be paid in accordance with TSX Venture Exchange policies. All securities issued as part of the offering will be subject to a hold period in Canada of four months plus one day from the closing of the offering.

About Cascadia Minerals Ltd.

Cascadia's flagship asset is the 177-square-kilometre Carmacks project, located within the traditional territory of the Little Salmon Carmacks and Selkirk first nations, 35 kilometres southeast of the past-producing Minto mine. The Carmacks project is road accessible, via a 13-kilometre access road that extends from the government-maintained Freegold Road northwest of the town of Carmacks in central Yukon. The project has an existing 40-person camp and numerous roads throughout the property, and is 10 kilometres from grid power.

The Carmacks Main deposit has a measured and indicated resource containing 651 million pounds (lb) of copper and 302,000 ounces (oz) of gold (36.3 million tonnes grading 0.81 per cent copper, 0.26 gram per tonne (g/t) gold, 3.23 g/t silver and 0.01 per cent molybdenum) or 1.07 per cent copper equivalent, and an inferred resource containing 38 million lb of copper and 13,000 oz of gold (2.9 million tonnes grading 0.60 per cent copper, 0.16 g/t gold, 2.34 g/t silver and 0.02 per cent molybdenum). A 2023 preliminary economic assessment demonstrated positive economic potential, with a $230.4-million posttax NPV (net present value) (5 per cent) and a 29-per-cent posttax IRR (internal rate of return) at $3.75 (U.S.) per lb copper and $1,800 (U.S.) per oz gold. A second case evaluated at $4.25 per lb copper and $2,000 per oz gold returned a $330.1-million posttax NPV (5 per cent) and a 38-per-cent after-tax IRR.

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 metres of 0.31 per cent copper with 0.30 g/t gold). High-grade copper and gold mineralization is found at surface over five-kilometre-long trend, with grab samples returning peak values of 3.88 per cent copper, 1,065 g/t gold and 267 g/t silver.

QA/QC (quality assurance/quality control)

The technical information in this news release has been approved by Andrew Carne, PEng, vice-president of corporate development for Cascadia and a qualified person for the purposes of National Instrument 43-101.

The mineral resources and economic analysis disclosed here are referenced from the 2023 technical report on the Carmacks project preliminary economic assessment (PEA), written by SGS Canada Inc. Pricing for the Carmacks project PEA base case economic analysis was $3.75 (U.S.) lb copper, $1,800 (U.S.) per oz gold and $22 (U.S.) per oz silver at an exchange rate of $1 (Canadian to 75 U.S. cents. 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.

Results referenced in this news release represent highlights only. Below detection values for gold, copper, silver and molybdenum have been encountered in drilling, soil and rock samples in these target areas. Readers are cautioned that grab samples are selective by nature and are not necessarily representative of the grade of mineralization on the property. Copper equivalent calculations use metal prices of $4 (U.S.) per lb for copper, $2,500 (U.S.) per oz for gold and $30 (U.S.) per oz for silver. Recovery factors of 82 per cent for copper, 70 per cent for gold and 69 per cent for silver were used, based on recovery projections from the 2023 PEA study.
