Mine No. 7

Alabama, United States · Underground

Operating
Coal
Workforce
The North portal facility was designed to accommodate up to 500 underground employees and initially provided a new entry point for 200 miners.
Overview
Mine No. 7 is an underground longwall mine in Jefferson and Tuscaloosa Counties, Alabama, producing premium low-volatile hard coking coal. It is one of the deepest vertical shaft coal mines in North America, with operations between 1,400 and 2,100 feet underground, extracting coal from the Blue Creek coal seam. As of 31 December 2023, it had approximately 51.1 million short tons of recoverable reserves.
Production
Combined production from Mine No. 4 and Mine No. 7 was 7.6 million short tons in 2023 and 8.2 million short tons in 2024. Combined production from Mine No. 7, Mine No. 4, and the new Blue Creek mine reached 9.3 million metric tons in 2025.
Processing
Run-of-mine coal is transported to the surface via a skip system to the preparation plant. The Mine No. 7 preparation plant services the mine and also utilizes the No. 5 preparation plant via an overland conveyor. A dry-slurry system was being installed to reduce water usage.
Equipment
Two longwall mining units, skip system, Mine No. 7 preparation plant, No. 5 preparation plant (via overland conveyor), dry-slurry system (being installed), hoist system with a 40-ton capacity.

Operating
GoldSilver
Mine life
5 years
Workforce
The operation sustains 450 direct jobs.
Overview
La Yaqui Grande is an operating mine owned by Alamos Gold Inc. in Sonora, Mexico, part of the Mulatos District.
Production
The first gold pour produced 991 ounces. In 2024, the Mulatos District, with La Yaqui Grande as the primary operation, produced 205,000 ounces of gold. For the full year 2025, the Mulatos District produced 141,600 ounces of gold, with La Yaqui Grande contributing 107,300 ounces. Stacking rates for the full year 2025 averaged 11,300 tonnes per day.
Processing
La Yaqui Grande utilises a heap leach process. The ore undergoes a three-stage crushing circuit before being agglomerated, stacked on an independent leach pad, and leached. The resulting gold-bearing solution is processed through carbon columns, and the loaded carbon is then taken to the main Mulatos plant for final processing.
Equipment
The mine has a separate crushing and screening circuit equipped with Sandvik machinery. This includes a CJ-615 Jaw Crusher, a CH-860i Secondary Cone Crusher, two CH-865i Tertiary Cone Crushers, a SG-1541 Grizzly Feeder, and three SL3062 Vibrating Screens. The processing plant has a capacity of around 700 tons of ore per hour.

Island Gold

Ontario, Canada · Underground

Operating
Gold
Opened
2007-01-01
Mine life
19 years
Workforce
In February 2023, the mine had 500 full-time employees and 500 contractors, with plans to increase the full-time workforce to approximately 600 after the current expansion phase.
Overview
Island Gold is an operating underground gold mine owned by Alamos Gold Inc. It is located in the province of Ontario, Canada, approximately 83 kilometres northeast of Wawa and near the town of Dubreuilville. The project is often referred to as the "Island Gold District," which comprises the high-grade Island Gold underground mine and the adjacent, large-tonnage Magino open-pit mine. Alamos Gold holds 100% ownership of the project. The primary commodity is gold. The mine is currently in production and is undergoing a significant expansion.
Production
Current processing capacity at Kremzar mill is 1,200 tonnes-per-day. Phase 3+ Expansion is designed to increase throughput to 2,400 tonnes per day. The broader 'Island Gold District' expansion plan targets a combined processing rate of 20,000 tonnes per day (3,000 tpd from underground and 17,000 tpd from the open pit) by 2028, projected to increase average annual gold production to 534,000 ounces. For 2025, the Island Gold District produced 250,400 ounces of gold.
Processing
Underground ore is processed at the on-site 1,200 tonnes-per-day Kremzar mill, with additional ore processed at the larger, adjacent Magino mill. Processing involves primary and secondary crushing, grinding, a gravity recovery circuit, cyanide leach, and a carbon-in-pulp/leach circuit to produce gold bars. The expanded Magino mill will eventually process all ore from both Island Gold underground and Magino open-pit operations.
Equipment
New shaft, new paste plant for backfill. Transition to shaft hoisting will significantly reduce the required haul truck fleet. The broader Island Gold District, which includes the Magino open-pit, utilises a fleet of haul trucks, hydraulic shovels, and front-end loaders.
Expansion
Significant Phase 3+ Expansion underway, including a new shaft to 1,379 metres depth, expected to be completed in late 2026. A significant expansion of the Magino mill to 20,000 tonnes per day is underway. A broader 'Island Gold District' expansion plan targets a combined processing rate of 20,000 tonnes per day by 2028.

Lithium
Mine life
18 years
Workforce
157 direct employees and 800 contractors during construction (end of 2024); expected to offer a workplace for about 300 people directly and through contractors once operational.
Overview
The Keliber Lithium Project's operations are situated across the municipalities of Kaustinen, Kokkola, and Kronoby in Central Ostrobothnia, Finland. The project is in the development and construction phase, with completion expected in Q1 2026. It involves both open-pit and underground mining of spodumene ore to produce battery-grade lithium hydroxide monohydrate.
Production
The refinery is expected to produce an estimated 15,000 tonnes of battery-grade lithium hydroxide monohydrate annually. The Päiväneva concentrator will have an annual capacity of 200,000 tonnes of spodumene concentrate.
Processing
The integrated production process involves mining spodumene ore, concentrating it at the Päiväneva facility through crushing, milling, and flotation, and then transporting the concentrate 66 kilometres to the Kokkola refinery. At the refinery, the concentrate undergoes heat treatment and a hydrometallurgical process, including sustainable soda pressure leaching technology, to produce battery-grade lithium hydroxide monohydrate.
Equipment
The project will develop four open-pit and three highly mechanised underground mining operations. The Päiväneva concentrator will have an estimated annual capacity of 200,000 tonnes of spodumene concentrate, involving crushing, milling, and flotation. The Keliber lithium refinery in Kokkola Industrial Park is designed to produce battery-grade lithium hydroxide through heat treatment and hydrometallurgical refining, developed with Metso.
