The Monte Cristo project is an exploration-stage asset located in Esmeralda County, Nevada, USA, and is part of Hecla Mining Company's Nevada portfolio. The project is situated on the Walker Lane Trend and is described as a six-mile mineralised trend with multiple targets. Hecla is advancing its Nevada exploration projects through systematic detailed mapping, geochemistry, and cross-section generation to bring targets to a drill-ready status. The Nevada portfolio is considered a high-impact development project and is a significant focus of the company's exploration budget, accounting for 22% of it. For 2026, Hecla has allocated $16 million for its Nevada project portfolio, more than three times the investment made in 2025. As of year-end 2025, the inferred resource for Monte Cristo was reported with a gold cut-off grade of 0.094 oz/ton, based on a minimum mining width of 5.0 feet. Associated metallurgical recovery is estimated at 85% for gold and 85% for silver. For year-end 2024, the inferred resource was noted with a gold cut-off grade of 0.10 oz/ton, with an estimated metallurgical recovery of 90% for both gold and silver. Drilling has shown intercepts greater than 0.1 oz/ton gold and greater than 5 oz/ton silver, while rock chip sampling has returned up to 0.46 oz/ton gold and 2.5 oz/ton silver in untested areas. In 2025, the US government granted FAST-41 status to Hecla's exploration sites in Nevada, which is expected to expedite federal reviews for significant infrastructure projects.

The Redcastle Gold Project is Redcastle Resources’ core Western Australian gold asset, located in the Eastern Goldfields around 62 kilometres east-southeast of Leonora. The project area includes Queen Alexandra and Redcastle Reef, which host the company’s current JORC-compliant mineral resource base of 42,000 ounces. Mining is focused on granted Mining Lease M39/318, where Redcastle has received regulatory approval and commenced operational mobilisation. The development pathway is based on shallow gold mining, contractor-led operations and third-party toll treatment rather than construction of a standalone processing plant, giving the project a lower-capital route into near-term production.

Marban is an advanced gold exploration project that could support a satellite open-pit mining operation to feed the Canadian Malartic complex mill. A technical evaluation envisions a 14,000 to 16,000 tonnes per day open pit operation. The project is expected to contribute an average of approximately 130,000 ounces of gold per year to the Canadian Malartic complex. Production could start as early as 2033.

The Marban project is expected to contribute an average of approximately 130,000 ounces of gold per year to the Canadian Malartic complex. A technical evaluation envisions a 14,000 to 16,000 tonnes per day open pit operation. Production could start as early as 2033.

Ore from the Marban project will be processed at the 60,000-tpd-capacity Canadian Malartic mineral processing facility.

In March 2025, Agnico Eagle Mines Limited acquired 100% of O3 Mining Inc., which included the Marban project. A technical evaluation was completed in the fourth quarter of 2025, which updated the probable mineral reserves to 1.58 million ounces of gold (51.6 million tonnes grading 0.95 g/t gold) as at 31 December 2025. The impact assessment for the Marban Gold Mine Project is currently suspended as of February 2023 at the request of the proponent. Agnico Eagle plans to integrate new drilling into an optimised pit design in 2026 and assess opportunities to redeploy mobile equipment from the Barnat pit at Canadian Malartic to minimise capital expenditures.

Agnico Eagle acquired the Wasamac project on March 31, 2023. A technical review of the project has been underway since the acquisition. The federal impact assessment process for the project was terminated on December 4, 2024, as the company could not complete the required studies within the legislated timeframe. The new project plan, which involves processing ore at an existing facility, may no longer meet the criteria for a federal impact assessment. The provincial environmental assessment process is still required and is expected to resume in 2026. The project envisions an underground long-hole stoping operation with cemented rockfill. There will be a single underground access ramp. Drilling activities were carried out in late 2024 and early 2025.

Estimated production is between 3,200 and 4,000 tonnes per day. A planned mining rate of approximately 3,200 tonnes per day is envisioned. Average annual gold production is expected to be approximately 90,000 ounces.

Ore will be transported by truck to the Canadian Malartic Complex for processing. The project will not have an on-site processing plant or tailings storage facility. Waste rock generated during construction will be progressively returned underground as backfill.
