The Tererro Copper-Gold-Zinc VMS Project is located approximately 120 kilometres north-east of Albuquerque in New Mexico. The project is currently in the exploration and permitting phase. An application for a regular exploration permit (SF040ER) was submitted to the New Mexico Mining and Minerals Division (MMD) in May 2019, and the permitting process is ongoing. The United States Forest Service determined that an Environmental Assessment will be required to review the Plan of Operations. The issuance of this Environmental Assessment was delayed in 2022 due to fires and post-fire recovery efforts in the region.

The Javelin VMS Project is an early-stage exploration project operated by Australian mining company New World Resources. The project's status is currently "exploration," a revision from the previously listed "feasibility." In January 2024, New World Resources commenced an initial diamond core drilling program at the project to test the Discus Copper Prospect. The project consists of a contiguous series of 100%-owned mining claims covering approximately 5,000 acres. It is located about 75 kilometres south-east of New World Resources' Antler Copper Deposit, near the Bagdad porphyry copper mine. The company is exploring the potential for the Javelin project to serve as a satellite source of ore, which could be transported to a future processing facility at the Antler Project.

Expected to employ 7,500 during peak construction and 4,000 long-term jobs once in production.

Development activity at the Reko Diq project has slowed, with Barrick extending a project review until mid-2027 due to escalating security risks. This review will assess security, capital, financing, scope, and timeline, potentially increasing budgets and delaying the first production target of late 2028.

The project is not yet in production. Initial estimates for the first years of operation are for the production of 200,000 tonnes of copper and 250,000 ounces of gold annually. Another estimate suggests annual production of 200-250 kilotonnes of copper.

The operation will produce a high-quality copper-gold concentrate. Development is planned in two phases. Phase 1 is planned to process 45 million tonnes of ore per annum (mtpa). Phase 2, planned from 2034, is expected to double the processing capacity to a combined 90 mtpa.

The Loulo-Gounkoto complex is located in the western region of Mali, near the border with Senegal and adjacent to the Falémé River. It consists of two distinct mining permits, Loulo and Gounkoto. The complex is owned by a partnership between Barrick Gold Corporation (80%) and the State of Mali (20%). A dispute with the government over Mali's 2023 mining code escalated in 2025. Barrick suspended operations on 14 January 2025, after the government restricted gold shipments and seized existing gold stock from the site. On 16 June 2025, a Malian court appointed a provisional state administrator to manage the mine. An agreement to resolve all disputes was announced in November 2025, which included a settlement payment from Barrick. The agreement led to the termination of the provisional administration and the dropping of all charges against Barrick and its employees. Barrick regained operational control on 16 December 2025, and the confiscated gold was returned on 18 December 2025. As part of the resolution, the government of Mali agreed to a 10-year extension for the Loulo mining permit.

The project will use a heap leach process. Run-of-mine ore will be crushed before being placed on a heap leach pad. Copper will be leached with acid, with the resulting solution undergoing solvent extraction and electrowinning to produce LME-grade copper cathodes. Following copper leaching, the ore will be rinsed and neutralised. This material will then be agglomerated and stacked on a separate heap leach pad for gold and silver recovery using a cyanide solution. Gold and silver will be recovered from the pregnant leach solution via the Merrill-Crowe zinc precipitation process and smelted into doré bars.

Mining will be conducted using diesel hydraulic face shovels and front-end loaders on 12-metre benches. Haul trucks will transport ore to the crusher. The project plans to implement an autonomous haulage fleet. The processing plant will feature a primary crusher and a closed-circuit secondary crushing system.

Currently in development stage with an updated pre-feasibility study released in February 2023.
