NORTHWEST UPSIZES FLOW THROUGH FINANCING TO $4.1 MILLION AND CLOSES FINAL TRANCHE

Northwest Copper Corp. has upsized, a second time, its non-brokered critical mineral flow-through (FT) private placement financing, originally announced on July 16, 2025, and July 29, 2025. Continued demand for the FT offering has allowed the company to increase the placement for a second time to an aggregate total of $4.1-million in gross proceeds. The final tranche of the FT offering, in an amount of $900,000, has closed and the company's $4.1-million FT offering is complete.

Chief executive officer Paul Olmsted stated: "The demand from investors for the flow-through financing and its closure has been a great success for the company. The continuing demand reflects the significant interest and confidence in our new strategic approach at Kwanika of targeting higher-grade zones within the existing mineral resources. This increased funding will allow the company to execute on its planned 2025 exploration drilling and metallurgical programs, and bring forward certain drill holes originally planned for 2026."

Geoff Chinn, vice-president of business development and exploration, said: "Closing of the financing has allowed for a staged approach to executing on the 2025 exploration program. Prework wildlife surveys at Kwanika are now done, the access road has been prepared, camp and core shack set-up are complete, and equipment, supplies and contractors are on site. We are excited to start the 5,135-metre drill program to confirm and expand higher-grade zones within the broader mineral resource. This is expected to support more selective bulk underground mining methods. Nearby targets, such as the Transfer target and the Andesite Breccia target, will be tested. These targets provide the company with the potential for discovering new zones of mineralization. In addition, we will collect samples from existing core to support a metallurgical program designed to fill gaps in previous test work and improve copper and gold recoveries, especially at finer-grind sizes."

The second upsizing of the FT offering increases the total FT offering from $3.5-million to an aggregate of $4.1-million in gross proceeds. The final tranche of the upsized FT offering includes subscriptions of 887,490 units at a price of 22.5 cents per FT unit for gross proceeds of $900,000. Each FT unit consists of one flow-through common share of the company and one-half of one non-transferable common share purchase warrant, with each FT warrant exercisable to purchase one additional common share of the company at an exercise price of 34 cents until Aug. 22, 2027. Proceeds of the flow-through placement will be used for exploration at Kwanika Central and the nearby Transfer and Andesite Breccia targets.

The FT shares will qualify as flow-through shares (within the meaning of Subsection 66(15) of the Income Tax Act (Canada)). An amount equal to the gross proceeds from the issuance of the FT shares will be used to incur eligible resource exploration expenses, which will qualify as: (i) Canadian exploration expenses (as defined in the tax act); and (ii) as flow-through critical mineral mining expenditures (as defined in Subsection 127(9) of the Tax Act). Qualifying expenditures in an aggregate amount not less than the gross proceeds raised from the issue of the FT shares will be incurred (or deemed to be incurred) by the company on or before Dec. 31, 2026, and will be renounced by the company to the initial purchasers of the FT shares with an effective date no later than Dec. 31, 2025.

Canaccord Genuity Corp. acted as the company's financial adviser for the FT offering. On the final tranche, the company incurred cash finders' fees of $50,250, issued 206,276 common shares for finders' fees and advisers' fees in lieu of cash, and issued 223,332 compensation warrants to eligible finders. Each compensation warrant is non-transferable and entitles the holder to acquire one common share of the company at 34 cents until Aug. 22, 2027.

All securities issued in the final tranche of the private placement (including the compensation shares and compensation warrants) are subject to a hold period expiring on Dec. 23, 2025.
