Comprehensive loss for the period	(1,747)	(1,591)	(7,547)	(6,951)

For the three-month period ended August 31, 2025, we reported a net loss of $1.7 million compared to a net loss of $1.6 million for the three-month period ended August 31, 2024. The increase in comprehensive loss in the third quarter of 2025, compared to the same quarter in 2024, was primarily driven by site activities of Ambler Metals LLC ("Ambler Metals") – the Company's 50/50 joint venture with South32 Limited (ASX, LSE, JSE: S32; ADR: SOUHY) ("South32") – during the summer for environmental baseline work and the start of a core re-boxing program.

For the nine-month period ended August 31, 2025, we reported a net loss of $7.5 million, compared to a net loss of $7.0 million for the same period in 2024. The increase in net loss was primarily driven by higher regulatory expenses and legal fees related to the Company's base shelf prospectus and at-the-market program (the "ATM Program") and our share of losses from Ambler Metals for the environmental baseline and core re-boxing programs. These increases were partially offset by lower office expenses and higher interest income earned.

Project Update

During the month of July 2025, Ambler Metals completed a summer maintenance field program at the Bornite camp site. Along with routine maintenance, the team also conducted an environmental baseline program to gather data to support the eventual mine permitting applications. The field work was completed safely and successfully with no reportable or lost time incidents. The annual biomonitoring program was completed with the Alaska Department of Fish and Game and the annual metrological and hydrological station maintenance program was completed with Boreal Environmental Services, a leading environmental consulting firm based in Alaska. Ambler Metals also commenced a multi-year core re-boxing program which will ensure the stored drill core is protected for an extended period of time. The field program was completed on budget and on schedule. The cash position of Ambler Metals at the end of the third fiscal quarter is approximately $3.7 million and expenditure levels of $4.5 million are tracking close to budget for the year.

Liquidity and Capital Resources

During the nine-month period ending August 31, 2025, we used $2.7 million for operating activities. The majority of these funds was spent on corporate salaries, professional fees to complete the Bornite preliminary economic assessment, and the establishment of the base shelf prospectus and ATM Program along with related regulatory filing fees with the United States and Canadian securities commissions. In addition, the Company incurred annual listing fees for the NYSE American Exchange and the Toronto Stock Exchage during the first fiscal quarter. These cash outflows were partially offset by $0.2 million received in financing activities related to proceeds from the exercise of stock options.

As at August 31, 2025, we had cash and cash equivalents of $23.4 million and working capital of $23.4 million, which we define as current assets less current liabilities. There is sufficient cash on hand to fund the initial fiscal 2025 budget of $3.1 million, as well as the subsequently approved expenditures related to the base shelf prospectus and ATM Program.

To ensure sufficient liquidity in the future to support our operations, administration expenses and contributions for our share of Ambler Metals, we have an effective base shelf prospectus that allows for the future issuance, from time to time, of up to $50.0 million in securities. We have also established an ATM Program whereby we may, from time to time and at our discretion, offer and sell the common shares having an aggregate gross sales price of up to $25.0 million under the ATM Program at the prevailing market price at the time of sale. As at October 2, 2025, we have not utilized the ATM Program.

We believe our current cash position is sufficient to meet our working capital requirement for the next 12 months. Beyond the next year, future cash requirements may vary materially from current expectations. We may need to raise additional funds in the future to support our operations, administration expenses and our contributions for our share of Ambler Metals.
