Summary of Operational Results

Operational Update

During Q2 2025, the Company mined a total of 3,877 tonnes of ore and 88,385 tonnes of waste, all of which came from the Siwash North Pit. The average ore grade delivered was 1.25 g/t gold, resulting in total gold ounces sold of 114 and a strip ratio of 22.8. During Q2 2024, the Company mined a total of 7,675 tonnes of ore and 551,033 tonnes of waste from the Siwash North Pit. The average ore grade delivered was 4.01 g/t gold, resulting in total gold ounces sold of 965 and a strip ratio of 71.8. The lower strip ratio in Q2 2025 was result of implementing a more targeted methodology, which led to reduced dilution and minimized mine loss.

The Company is looking to strategically increase its production outputs as the improvements to mine methods, grade control, ore processing and sampling are realized. We recognize that a large increase in production prior to the improvements may be at a significant loss in potential earnings.

Summary of Financial Results

For Q2 2025, the Company recorded a net loss of $2.1 million compared with a net loss of $1.0 million for Q2 2024. Lower metal sales volumes due to low production, combined with lower realized prices for gold, resulted in a decrease in revenue to $0.1 million from $2.2 million for Q2 2024. Mine operating income for Q2 2025 was an operating loss of $1.2 million compared with a mine operating loss of $0.3 million for Q2 2024.

Corporate Update

The Company's mining contractor and partner, Nhwelmen Construction Limited Partnership ("Nhwelmen"), renegotiated its accumulated debts by converting $1,250,000 into Company common shares, and placing the remaining balance of the $6,534,851, on a medium-term loan. As a sign of good faith and trust, both parties have executed a General Security Agreement ("GSA") with respect to the Company's wholly owned subsidiary, Elk Gold Mining Corp.

The Debenture is convertible into common shares of the Company at a conversion price of $0.08 per share of the Company, at any time immediately preceding the maturity date.
