Newmont is the world's largest gold miner. It bought Goldcorp in 2019, combined its Nevada mines in a joint venture with competitor Barrick later that year, and also purchased competitor Newcrest in November 2023. Its portfolio includes 17 wholly or majority owned mines and interests in two joint ventures in the Americas, Africa, Australia and Papua New Guinea. The company is expected to produce roughly 6.9 million ounces of gold in 2024. However, after buying Newcrest, Newmont is likely to sell a number of its higher cost, smaller mines accounting for 20% of forecast sales in 2024. Newmont also produces material amounts of copper, silver, zinc, and lead as byproducts. It had about two decades of gold reserves along with significant byproduct reserves at the end of December 2023.

Based in Toronto, Barrick Gold is one of the world's largest gold miners. In 2023, the firm produced nearly 4.1 million attributable ounces of gold and about 420 million pounds of copper. At year-end 2023, Barrick had about two decades of gold reserves along with significant copper reserves. After buying Randgold in 2019 and combining its Nevada mines in a joint venture with competitor Newmont later that year, it operates mines in 19 countries in the Americas, Africa, the Middle East, and Asia. The company also has growing copper exposure. Its potential Reko Diq project in Pakistan, if developed, could double copper production by the end of the decade.
