Overview
The Libby Exploration Project, operated by Hecla Mining Company, is located in Lincoln County, Montana, south of Libby. The project, acquired in 2016, is advancing with underground exploration to gather geological, hydrological, and environmental data to determine economic feasibility. As of 2024, it has an Inferred Resource of 112.2 million tons grading 0.7% copper and 1.6 oz/t silver. The project has faced environmental opposition.
Expansion
The U.S. Forest Service issued a final decision notice and finding of no significant impact, allowing the project to advance. The new Plan of Operations has been authorised, and underground exploration and data collection can now proceed.

Overview
The Libby Exploration Project is an underground silver and copper exploration operation. In October 2025, the U.S. Forest Service authorized the Plan of Operations, allowing underground exploration and evaluation activities to collect data for project engineering, environmental requirements, and overall feasibility. The project is expected to last for approximately 16 years, including post-reclamation monitoring. Activities include dewatering and rehabilitating the existing Libby Creek adit, extending the tunnel, and constructing additional tunnels for exploration. As of March 2026, the project's approval was being challenged in court.

Overview
Mopani Copper Mines PLC has since 2014 sunk and equipped three brand new shafts to replace the old infrastructure at both Nkana and Mufulira mine sites, which dates back to the 1930s. The three new shafts are Syclinorium and Mindola Deeps Shafts at Nkana Mine in Kitwe and The Henderson Shaft at Mufulira Mine site. Mopani has also built a brand new Concentrator at Nkana mine site, The New Syclinorium Concentrator. The new infrastructure is expected to extend the life of the mine by over 25 years, improve production efficiencies and safeguard the existing jobs while guaranteeing Mopani’s continued contribution to growing the Zambian economy.

Equipment
The operation will be a conventional truck-and-shovel open pit mine. This will include the use of 360-ton trucks.
Expansion
The reconstitution of the Reko Diq project was completed in December 2022. In February 2025, Barrick filed an updated NI 43-101 technical report for the project. As of April 2026, Barrick has slowed development activity and extended the project review until mid-2027 due to escalating security risks in the region. This is expected to lead to significant increases in the previously estimated capital budget and timeline. The initial target for first production was the end of 2028, which is now under review. The estimated capital cost for Phase 1 was between $5.6 billion and $6.0 billion, and for Phase 2 was between $3.3 billion and $3.6 billion.

Overview
The Troy Mine is a closed underground copper and silver mine located in Lincoln County, Montana. The ore body was discovered in 1963, and after extensive exploration, the mine was developed by ASARCO, with construction beginning in 1979. Hecla Mining Company acquired Revett Minerals in March 2015 and announced the permanent closure of the Troy Mine.
Production
Production overview - 2012: silver 1.325 Moz; 1984: copper 17200000 kg, silver 4269000 oz.
Processing
The Troy Mine utilised the room and pillar mining method. Ore was transported by trucks to an underground crusher and then moved to the mill via a conveyor system. The milling process involved crushing, grinding, and concentration by flotation.
Equipment
underground crusher, conveyor system
Expansion
In March 2015, Hecla Mining Company acquired Revett Minerals, which led to the permanent closure of the Troy Mine.

Development is planned in two phases, with a combined processing capacity of 90 million tonnes per annum. Phase 1 is designed for a throughput of approximately 40-45 million tonnes per annum, with Phase 2 expected to double this capacity. A potential Phase 2 expansion could increase copper production to 400,000 tonnes per year. The reconstitution of the project was completed in December 2022. In March 2026, Barrick announced it was slowing development activity and extending the project's review period by 12 months from July 2026, citing security concerns in the region. This decision is expected to affect previously stated budgets and timelines.

Workforce
As of 2023, the Phoenix mine had a workforce of 474 company employees and 351 contract employees. In 2022, the workforce consisted of 450 company employees and 383 contract employees.
Overview
The Phoenix mine is an open-pit gold, silver, and copper operation located in Lander County, Nevada, approximately 20 kilometres south of Battle Mountain. It is owned and operated by Nevada Gold Mines, a joint venture between Barrick Gold Corporation (61.5% interest, operator) and Newmont Corporation (38.5% interest). The mine is part of the larger Battle Mountain Mining District.
Production
In 2023, the Phoenix mine produced 199,994 ounces of gold, 952,702 ounces of silver, and 35,406,713 pounds of copper. Production in 2022 was 109,000 ounces of gold, 1,289,000 ounces of silver, and 35,600,000 pounds of copper. In 2021, the mine produced 173,067 ounces of gold, 1,322,700 ounces of silver, and 36,736,179 pounds of copper.
Processing
The mine's processing facilities include a flotation mill, a carbon-in-leach plant, a copper leach pad, and a solvent extraction-electrowinning (SX/EW) plant. Ore from the open-pit is processed to produce a gravity gold concentrate and a copper-gold flotation concentrate, with additional gold recovered through cyanide leaching of flotation tailings.
Equipment
The mine uses a fleet of haul trucks and shovels or loaders.
Expansion
The Greater Phoenix Project, approved in 2018, involves consolidating five existing pits into an expanded Phoenix Pit and increasing its depth, extending the mine's operational life to 2063. A truck reinvestment strategy is underway from 2024 to 2026. Opportunities for expanding copper production are being explored, and in 2021, a letter of intent was signed to investigate recovering critical metals like nickel, cobalt, scandium, and zinc from heap leach solutions.

SilverGoldCopperLeadZinc
Overview
The Kinskuch property is located in the Golden Triangle of northwestern British Columbia. It is now part of Dolly Varden's larger Kitsault Valley Project, which covers approximately 77,000 hectares. The acquisition connected the Kitsault Valley, Big Bulk, and Kinskuch projects into a consolidated, district-scale land package. The property is considered underexplored but prospective for silver, gold, and copper mineralisation, situated within the favourable Jurassic-age Hazelton Group volcanic rocks. The addition of the Kinskuch property adds the Illiance trend to Dolly Varden's existing Kitsault Valley trend. The property has a renewed five-year Exploration Permit covering both Nisga'a and Gitanyow Traditional Lands.
Expansion
Since the acquisition, the Kinskuch property has been integrated into the broader exploration strategy for the Kitsault Valley Project. In 2025, Dolly Varden conducted a significant diamond drilling program across the Kitsault Valley Project, which was expanded from 35,000 metres to over 56,000 metres. While specific drilling targets on the Kinskuch property itself are not detailed in recent announcements, the overall program is focused on resource expansion and exploring new mineralised zones. The Big Bulk property, which is prospective for copper-gold porphyry mineralisation, trends south onto the Kinskuch Project.
