Beginning in the 1930s, Newmont spends the next three decades growing steadily by acquiring new operations and diversifying its mining portfolio through joint ventures with established mining companies to include copper, gold and other minerals.
The Company experiments with new processing techniques for metals such as nickel and lithium, creates the largest cement plant in the United States, refines copper for use in the automotive industry, and puts together a consortium to acquire Peabody Coal – the largest coal miner in the United States. In all, Newmont grows its operations, producing 28 different products from mines, wells, plants and refineries in the United States, Canada, Africa, Peru and elsewhere.
In Nevada, Newmont discovers the world’s first submicroscopic or “invisible” gold at Carlin in the early 1960s and begins production on the first open pit gold mine in the world. Its mines on the Carlin Trend are the first in North America to produce 1 million ounces in a year. Carlin becomes the foundation of Newmont’s rise in the gold market.
