Commercial production began on 1 July 2021. It is an underground copper mine in Lualaba Province, Democratic Republic of Congo, utilizing flotation to produce copper concentrate, with an on-site direct-to-blister copper smelter. The complex is powered by clean, renewable hydro-generated electricity and employs over 6,800 full-time employees.

Production overview - 2025: copper 388838 t; 2024: copper 437061 t.

The complex utilises flotation to produce copper concentrate. The total design processing capacity was increased to 14.2 million tonnes per annum with the completion of the Phase 3 concentrator. First concentrate from the Phase 3 concentrator was achieved on 10 June 2024, and it reached commercial production in August 2024. A debottlenecking program completed in February 2023 increased the processing capacity of the Phase 1 and 2 concentrators to a combined 9.2 million tonnes per year. A 500,000-tonne-per-annum on-site direct-to-blister copper smelter was constructed, with first anode production on 29 December 2025. The smelter is the largest in Africa.

The Phase 3 expansion includes two new underground mines, Kamoa 1 and Kamoa 2, and a new 5 million tonne-per-year concentrator plant. The Phase 3 concentrator was completed in May 2024, ahead of schedule. Once fully ramped up, the Phase 3 expansion is expected to increase annualised copper production to more than 600,000 tonnes. A potential Phase 4 expansion is planned for later in the decade which would increase total processing capacity to 19.2 million tonnes per annum. An updated mine plan released in March 2026 supports a ramp-up of production to over 500,000 tonnes of copper per annum from 2028 onwards.

Production overview - 2025: lithium 15200000 t; 2024: lithium 48500000 t.

The site has a 1 million tonne per annum processing plant to produce spodumene concentrate.

Mining operations were paused in January 2024, and the site transitioned to care and maintenance in mid-2024 due to lithium market conditions. A restart study was completed in 2025. In March 2026, Core Lithium announced a Final Investment Decision (FID) and secured funding for the restart of the Finniss Lithium Operation. The restart will focus on underground mining at the BP33 deposit, supplemented by the remaining ore from the Grants open pit. The restart is expected by September 2026.

The Connaught project is an exploration-stage asset with potential for copper-molybdenum-gold porphyry mineralisation and high-grade epithermal veins containing silver, lead, zinc, gold, and copper. It was acquired by Hecla Mining Company in 2023 through the acquisition of ATAC Resources Ltd. Historical small-scale extraction from shallow pits occurred in 1966 and 1976.

The Casa Berardi mine, in operation for over 35 years, has produced over 3.2 million ounces of gold. It is transitioning from a combined underground and open-pit operation to a surface-only operation, with lower-margin east mine underground operations ceased in July 2023.

Production overview - 2025: gold 91160 oz; 2023: gold 90363 oz, silver 22415 oz.

Orezone Gold Corporation plans to integrate the Casa Berardi operations throughout 2026 and intends to provide updated guidance for the mine in the second quarter of 2026. The new owner has initiated trade-off studies to optimise the current mine plan and evaluate an increase in underground production. An updated mine plan and economic study are expected to be published in the fourth quarter of 2026. Orezone also plans to commence a multi-year exploration drilling program of 80,000 to 100,000 metres annually.

The San Juan Silver project is a high-impact development project in the historic Creede Mining District in Colorado. Hecla Mining Company has single ownership of the entire district. The project's focus is on the historic Bulldog silver mine, which produced 25 million ounces of silver between 1969 and 1985. Hecla is strategically advancing the project to access the underground infrastructure to confirm and expand on existing resources. A 2013 surface drilling program intersected high-grade mineralisation 1,400 feet north of the Bulldog workings, confirming district-scale potential. The project has 30 miles of permissive strike length along known mineralised structures. San Juan Silver accounted for 1% of Hecla's exploration budget. As of February 2024, the project had an inferred resource of 38,203,000 ounces of silver, 49,400 tons of lead, and 39,850 tons of zinc.

Production overview - 2024: silver 38203000 oz, lead 49400 t, zinc 39850 t.

The Rock Creek project, located in Sanders County, Montana, is a silver and copper project held by Hecla Mining Company. As of early 2026, the company is not actively seeking permits to construct the mine. This follows a 2021 federal court decision that invalidated the project's approvals from the U.S. Forest Service and U.S. Fish and Wildlife Service. The court ruled that the agencies had violated the Endangered Species Act by not fully considering the impacts of the entire proposed mine on grizzly bears and bull trout. Consequently, the Rock Creek project currently has no federal authorisation to proceed, and new environmental analyses would be required for any future permit applications. Hecla Mining Company's current focus in the region is on its Libby Exploration Project. The company acquired the Rock Creek project in June 2015 through the acquisition of Revett Mining Company. As of 31 December 2025, the project's inferred mineral resources were reported based on a minimum thickness of 15 feet and a Net Smelter Return cut-off value of $35.10 per ton. The estimated metallurgical recoveries are 88% for silver and 92% for copper. The resources are adjusted based on mining restrictions defined by the U.S. Forest Service in a June 2003 'Record of Decision'.

The mine is not in production.

The Republic project is an exploration-stage asset located in the historic Republic Mining District in Ferry County, Washington. It is fully owned by Hecla Mining Company and covers 3,583 acres, which includes several historically productive trends. Hecla categorises the project as an emerging opportunity and focuses its exploration on identifying potential mineral deposits that are concealed by post-mineral cover.

The Monte Cristo project is an exploration-stage asset in Hecla Mining Company's Nevada portfolio. It is situated in the Walker Lane Trend, a significant mineralized zone. The project is characterised by a six-mile mineralised trend with multiple targets. Historical exploration has identified high-grade gold and silver at the surface. Hecla is engaged in ongoing detailed mapping, geochemistry, and cross-section generation to advance targets to a drill-ready status. The project is located on Bureau of Land Management (BLM) administered land and consists of 344 unpatented lode claims, covering approximately 6,880 acres.

The Libby Exploration Project, formerly known as Montanore, is a silver and copper deposit owned by Hecla Mining Company through its wholly-owned subsidiary, Montanore Minerals Corporation (MMC). The project is located approximately 20 miles south of Libby in Lincoln County, Montana. As of early 2026, the project is in an exploration and evaluation phase, with the environmental review and permitting process estimated to be completed by 10 June 2026. On 3 October 2025, the U.S. Forest Service (USFS) issued a final Environmental Assessment and a Decision Notice with a finding of no significant impact, authorising Hecla to proceed with its Plan of Operations. The plan involves underground exploration to gather data to inform project engineering, environmental requirements, and overall feasibility. As of 31 December 2024, the project had an Inferred Resource of 112.2 million tons. On 31 March 2026, a coalition of environmental organisations filed a lawsuit against the U.S. Forest Service and U.S. Fish and Wildlife Service. The lawsuit challenges the project's approvals, citing an inadequate environmental review process and potential impacts on the Cabinet Mountains Wilderness, water quality, and species protected under the Endangered Species Act, such as bull trout and grizzly bears.

The authorised Plan of Operations includes dewatering and rehabilitating an existing 7,000-foot adit. The company then proposes to extend the tunnel by 4,200 feet and construct additional tunnels to facilitate exploration drilling and data collection.

The Kinskuch property is located in the Golden Triangle of British Columbia and is now part of Dolly Varden Silver's larger Kitsault Valley Project. The property is contiguous to the east and south of the existing Kitsault Valley Project. The acquisition of the Kinskuch property by Dolly Varden Silver has significantly increased the size of their Kitsault Valley Project to approximately 77,000 hectares. The addition of the Kinskuch property has tripled the total strike length of the favourable Jurassic-age Hazelton Group volcanic rocks. The Kinskuch property is considered underexplored, with limited modern exploration work. Dolly Varden Silver has indicated that initial plans for the property, following the acquisition in 2025, would include geological mapping and reconnaissance. There is potential for porphyry and skarn-style copper and gold mineralisation on the Kinskuch Project, which is on trend with the Big Bulk property.

The Polaris Exploration Project, a ten-year gold exploration plan, completed its federal permitting process in March 2026, clearing the way for exploration activities to commence.

The Aurora Mining District has a historical production of 1.9 million ounces of gold and 20 million ounces of silver. Historical underground production averaged 2.24 ounces per ton of gold.

There is an existing 600-ton-per-day mill on site. A minor modification to the mine's Water Pollution Control Permit was completed to allow the recommencement of mill operations to process historical tailings from Tailings Storage Facility 1 (TSF1). The reprocessed tailings are to be deposited in the fully lined Tailings Storage Facility 2 (TSF2), which was commissioned in 2012.

Hecla's 2026 exploration program, the Polaris Exploration Project, will test multiple high-grade epithermal vein systems. Targets include near-surface systems (Martinez, Juniata, Ann) and deeper preserved systems (Brawley Peak, Sawtooth Ridge, Polaris). The Plan of Operations allows for the construction of up to 25 miles of new or reconstructed roads and up to 250 drill pads over a ten-year period, with total surface disturbance not to exceed 150 acres. The reclamation permit authorises an initial Phase I disturbance of 28.9 acres, with a subsequent phase of 121.1 acres proposed.

Approximately 250 employees and contractors as of January 2023.

The Rock Creek project is an underground silver and copper mine located in Sanders County, Montana, United States. It is owned and operated by Hecla Mining Company, which acquired the project in June 2015. Currently, Hecla is not actively pursuing permits for the construction of the Rock Creek mine and has withdrawn the Plan of Operations from consideration by the United States Forest Service. The company is instead focusing on the Libby Exploration Project at the nearby Montanore site. Legal and environmental challenges have played a significant role in the project's status, with court rulings revoking previous authorisations for the mine. A 2021 court ruling invalidated the U.S. Forest Service's approval for the mine's evaluation phase, citing violations of the Endangered Species Act. As a result, the Rock Creek mine currently has no federal authorisation to proceed.

Production overview - 2025: silver 148291000 oz, copper 595167.5 t.

The Republic Project is an exploration-stage asset wholly owned and operated by Hecla Mining Company in Ferry County, Washington.
