Pascua-Lama is a gold, silver, and copper project operated by Barrick Gold Corporation, located on the border of Chile and Argentina. Designed as a large-scale open-pit operation, construction began in October 2009 but was suspended in Q4 2013. The Chilean portion is transitioning to closure, while the Argentinian portion is being re-evaluated.

Conventional mining techniques including drilling and blasting. Ore was to be transported to a primary crusher in Chile, then conveyed through a 2.7-kilometre tunnel to processing facilities in Argentina. The plant was designed for 45,000 tonnes per day throughput, involving secondary crushing, milling, washing, conventional flotation for copper concentrates, and cyanide leaching for gold and silver doré.

Barrick is undertaking a significant drilling program with plans for 370km of surface drilling and 80km of underground drilling by the end of 2028. Construction of the Bullion Hill exploration decline portal is expected to commence in 2026, providing underground access to deeper parts of the orebody from 2027. By 2029, the company plans to have 34km of underground development connecting Bullion Hill with the Goldrush development. Initial test stoping is anticipated to begin shortly after 2029. A three-year pre-feasibility study was planned to start in 2025.

A major plant expansion and mine life extension project is underway to sustain average annual gold production above 800,000 ounces (100% basis) and extend the mine's life beyond 2040. The total estimated capital cost for the project is US$2.1 billion. Phase 1 of the expansion, related to the process plant, was completed and achieved commercial production in the third quarter of 2024. A delayed ramp-up occurred due to the failure of a feed conveyor, which has since been reconstructed. Phase 2 focuses on a new tailings storage facility (TSF) called El Naranjo. The feasibility study for the Naranjo TSF was completed in the third quarter of 2024, and tenders for major construction contracts have been released. Early works for the new TSF are expected to begin in 2025. The project requires a resettlement action plan for local communities.

The Fire Creek Mine is located in Lander County, Nevada. In the second quarter of 2021, the mine was placed on care and maintenance after the processing of the remaining non-refractory ore stockpile was completed. As of December 2025, the Nevada Operations, which include Fire Creek, remained on care and maintenance.

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.
