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 t he 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 b ase 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 program s. These increases were partially offset by lower office expenses and h igher 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 consulti ng 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 b ase 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 b ase shelf prospectus that allows for the

future issuance, from time to time, of up to $50.0 million in s ecurities. 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 P rogram.

We believe our current cash position is sufficient to meet our working capital requirement for the next 12

months. Beyond the next year, f uture 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.
