Previous wording

Our current geographic focus for the evaluation of potential mineral property assets is in North and South America; however, we have conducted property evaluations for potential acquisition in other parts of the world. At June 30, 2025, we consider our Golden Crest Project in South Dakota, our carried interest in the Florida Canyon Project in Peru, and our interest in the Lik Project in Alaska to be our core mineral property assets. In addition, we own the Cat Creek Project in Colorado, which has not been explored to the degree of any of our three core assets, described above. We are conducting exploration activities in the United States on our own at the Golden Crest and Cat Creek Projects and through joint ventures operated by our partners in Peru at the Florida Canyon Project and in Alaska at the Lik Project. From time to time we also conduct potential acquisition evaluations in other countries located in South and North America.

As of June 30, 2025, we have balances of cash and short-term investments that we anticipate using, in part, to (i) fund costs and activities intended to further the exploration of our Lik Project, Florida Canyon Project, Golden Crest Project and Cat Creek Project; (ii) conduct reconnaissance exploration and (iii) potentially acquire additional mineral property assets. The fluctuations in precious metal and other commodity prices contribute to a challenging environment for mineral exploration and development, which has created opportunities as well as challenges for the potential acquisition of advanced mineral exploration projects or other related assets at potentially attractive terms.

Previous wording

Our net exploration expense increased to $671,000 during the three months ended June 30, 2025 compared to exploration expense of $487,000 during the three months ended June 30, 2024 primarily as a result of (i) an increase in exploration expense at our Golden Crest Project to $635,000 during the three months ended June 30, 2025 compared to $450,000 during the three months ended June 30, 2024 as a result of the commencement of drilling at Golden Crest during the second quarter of 2025, with no drilling in the second quarter of 2024; and (ii) an increase in exploration expense at our Lik Project in Alaska during the three months ended June 30, 2025 of $19,000 compared to exploration expenditures of $16,000 during the three months ended June 30, 2024. Drilling commenced in June 2025 at our Golden Crest Project which resulted in approximately $347,000 in drilling expenditures in the three months ended June 30, 2025 with no similar amount during the three months ended June 30, 2024. Partially offsetting these increases in exploration expense were reductions of the limited work at our Cat Creek Project and reconnaissance work during both the three months ended June 30, 2025 and 2024. We have budgeted approximately $3,910,000 for the full-year exploration expenditure for 2025, which includes approximately $1,911,000 for drilling at the Golden Crest Project. We expect our full-year exploration expenditures for 2025 to be comparable to our full-year exploration expenditures for 2024.

Our net exploration expense decreased to $1,645,000 during the three months ended September 30, 2025 compared to exploration expense of $2,067,000 during the three months ended September 30, 2024 primarily as a result of (i) lower exploration expense at our Golden Crest Project to $1,522,000 during the three months ended September 30, 2025 compared to $1,957,000 during the three months ended September 30, 2024 as a result of fewer holes being drilled as well as a slightly lower cost per hole for our drilling program during the three months ended September 30, 2025 compared to the drilling program during the three months ended September 30, 2024; and (ii) reductions in our exploration activity at our Cat Creek Project and reconnaissance work during the three months ended September 30, 2025 to $15,000 compared to exploration expense of $29,000 for those projects during the three months ended September 30, 2024. Partially offsetting these decreases in exploration expense were (i) an increase in exploration expense at our Lik Project in Alaska to $102,000 during the three months ended September 30, 2025 compared to exploration expense of $81,000 during the three months ended September 30, 2024; and (ii) work performed at our newly-acquired Bright Angel Project during the three months ended September 30, 2025 of $6,000 with no similar expenditures in 2024. We have budgeted approximately $3,910,000 for the full-year exploration expenditure for 2025, which includes approximately $1,911,000 for drilling at the Golden Crest Project.

We recorded $125,000 of stock option compensation expense for the amortization of unvested grant date fair value with a credit to additional paid-in-capital during the three months ended June 30, 2025 compared to $356,000 of stock option compensation expense during the three months ended June 30, 2024. These non-cash charges related to the expense for vesting on stock options outstanding during the three months ended June 30, 2025 and 2024. The primary reason for the decrease in stock option compensation expense during the three months ended June 30, 2025 compared to the three months ended June 30, 2024 was as a result of the grant of a total of 2,125,000 options in the second quarter of 2024, which included amortization of 25%, or $280,000 on the grant date of the total grant date fair value of $1,120,000, with no similar grant date amortization during the three months ended June 30, 2025.

We recorded interest and dividend income of $52,000 during the three months ended June 30, 2025 compared to interest income of $106,000 during the three months ended June 30, 2024. This decrease was primarily due to a decrease in our funds held in our money market account during the three months ended June 30, 2025 compared to the funds held in our money market account during the three months ended June 30, 2024. Our dividend income potion of interest and dividend income during in the three and six months ended June 30, 2025 of $2,000 and $5,000, respectively, was comparable to the same periods of 2024.

Current wording

We recorded interest and dividend income of $82,000 during the three months ended September 30, 2025 compared to interest income of $94,000 during the three months ended September 30, 2024. This decrease was primarily due to a decrease in our funds held in our money market account during the three months ended September 30, 2025 compared to the funds held in our money market account during the three months ended September 30, 2024 as well as a lower average interest rate earned on our short-term money market account during the three months ended September 30, 2025 compared to 2024.

We regularly perform evaluations of our mineral property assets to assess the recoverability of our investments in these assets. All long-lived assets are reviewed for impairment whenever events or circumstances change which indicate the carrying amount of an asset may not be recoverable utilizing guidelines based upon future net cash flows from the asset as well as our estimates of the geological potential of an early-stage mineral property and its related value for future sale, joint venture or development by us or others. During the three and six months ended June 30, 2025 and 2024, we recorded no property impairments.

We recorded interest and dividend income of $98,000 during the six months ended June 30, 2025 compared to interest and dividend income of $201,000 during the six months ended June 30, 2024.
