First Quarter 2025 Florida Canyon Mine Operational Update

The Florida Canyon Mine produced 19,323 ounces of gold and sold 19,540 ounces of gold during the first quarter 2025. Gold production exceeded expectations, partly due to the recovery and processing of approximately 2,000 ounces of previously unrecovered gold confined within an electrowinning tank as part of a one-time efficiency improvement project. Strong gold production was further supported by the continued ramp-up of solution flow rates through the heap leach pads and new carbon-in-column circuit commissioned in late 2024.

Forward‐looking statements necessarily involve known and unknown risks and uncertainties, which may cause actual performance and financial results in future periods to differ materially from any projections of future performance or result expressed or implied by such forward‐looking statements. These risks and uncertainties include, but are not limited to: general business, economic and competitive uncertainties; the actual results of current and future exploration activities; conclusions of economic evaluations; meeting various expected cost estimates; benefits of certain technology usage; changes in project parameters and/or economic assessments as plans continue to be refined; future prices of metals; possible variations of mineral grade or recovery rates; the risk that actual costs may exceed estimated costs; geological, mining and exploration technical problems; failure of plant, equipment or processes to operate as anticipated; accidents, labour disputes and other risks of the mining industry; delays in obtaining governmental approvals or financing; risks related to local communities; the speculative nature of mineral exploration and development (including the risks of obtaining necessary licenses, permits and approvals from government authorities); title to properties; and other factors beyond the Company's control and as well as those factors included herein and elsewhere in the Company's public disclosure. Although the Company has attempted to identify important factors that could cause actual actions, events or results to differ materially from those described in the forward-looking statements, there may be other factors that cause actions, events or results not to be as anticipated, estimated or intended.
