Insights

Mining Operations Analyst

Strong Q3 production and a cash balance of $81.2 million support near‑term operations and planned capacity expansion.

Florida Canyon produced 20,653 oz of gold in Q3 2025 and sold 20,265 oz, with a processed grade of 0.20 g/t and a recovery of 60.7%. These metrics, together with the reported $81.2 million cash balance, indicate the operation generated meaningful operating cash flow while funding capitalized stripping, equipment refresh, and leach pad expansion.

Outcomes depend on a few operational items: the higher strip ratio of 1.34 was driven by intentional capitalized waste stripping and a temporary water shortage that has been resolved; continued recovery performance relies on Phase IIIa/IIIb pad commissioning and maintained solution flow rates. The fleet revitalization—arrival and commissioning of a new Hitachi shovel, and delivery of eight new 150‑ton haul trucks starting in Q4 2025 into Q1 2026—should reduce rental reliance and aim to lower mining cost per ton once fully integrated.

Watch for three near‑term, monitorable items: the full third quarter financial release and call on November 12–13, 2025; commissioning and ramp timing for the Phase IIIb heap leach pad in Q4 2025; and incremental impacts from the new fleet on operating cost and productivity through Q1 2026. These items will clarify whether the reported cash strength and production are durable.

The Florida Canyon Mine ("Florida Canyon") produced 20,653 ounces of gold and sold 20,265 ounces of gold during the third quarter 2025, which is in-line with the Company's expectations. Strong gold production continues to be supported by the recovery of gold ounces recently placed on the Phase IIIa heap leach pad and by residual ounces recovered from Phases I and II leach pads. Gold production levels were further supported by increased solution flow rates through the leach pads and the new carbon-in-column circuit commissioned late in 2024. The Company expects to meet its gold production guidance for 2025.

The increased strip ratio at Florida Canyon during the third quarter 2025 is a result of the Company's stated commitment of reinvestment through increased capitalized waste stripping and ramping up new mining areas. Waste movement also increased during the third quarter 2025 due to a provisional adjustment of the mine sequence to overcome dust suppression challenges caused by a temporary water shortage in the dry summer months. The temporary water shortage was caused by a problematic historic water well, which has since been successfully replaced.

During the third quarter 2025, construction of the Phase IIIb heap leach pad at Florida Canyon continued with commissioning expected in the fourth quarter 2025. Florida Canyon is also currently undergoing a revitalization of its mining fleet. As part of this effort, refurbishment is underway on haul trucks and loaders currently on site and orders have been placed for several new key pieces of equipment, including eight new 150 ton Caterpillar haul trucks, a new Caterpillar loader, and a new Hitachi mining shovel. The mining shovel has arrived on site and will be assembled, commissioned, and put into operation in the fourth quarter 2025. Delivery of the new haul trucks will commence in the fourth quarter 2025 and continue into the first quarter 2026. The refurbished existing fleet and key new pieces of equipment are expected to reduce reliance on expensive rental equipment, increase mining productivity, and lower mining cost per ton over the next several years at Florida Canyon.
