Based in Toronto, Barrick Gold is one of the world's largest gold miners. In 2024, the firm produced nearly 3.9 million attributable ounces of gold and about 430 million pounds of copper. At year-end 2024, 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.

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 sell roughly 5.6 million ounces of gold in 2025 from its core mines after selling six higher-cost, smaller mines. 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 2024.

Occidental Petroleum is an independent exploration and production company with operations in the United States, Latin America, and the Middle East. At the end of 2023, the company reported net proved reserves of nearly 4 billion barrels of oil equivalent. Net production averaged 1,327 thousand barrels of oil equivalent per day in 2024 at a ratio of roughly 50% oil and natural gas liquids and 50% natural gas.

Freeport-McMoRan owns stakes in 10 copper mines, led by its 49% ownership of the Grasberg copper and gold operations in Indonesia, 55% of the Cerro Verde mine in Peru, and 72% of Morenci in Arizona. It sold around 1.2 million metric tons of copper (its share) in 2024, making it the one of the world’s largest copper miners by volume. It also sold about 900,000 ounces of gold, mostly from Grasberg, and 70 million pounds of molybdenum. It had about 25 years of copper reserves at end December 2024. We expect it to sell similar amounts of copper midcycle in 2029, though we expect gold volumes to decline to about 700,000 ounces then due to falling production at Grasberg.
