Strategic Metals Mining

Strategic metals mining typically refers to metals such as copper, nickel and precious metals including platinum, palladium and gold.

These metals are considered strategic based on their importance to our domestic economy, national security applications and the emerging green economy, while also facing increasing global demand and our country’s current reliance on imported supplies.

In 2017, the U.S. imported 760,000 metric tons of copper, 150,000 metric tons of nickel, and 128,000 kilograms of palladium and platinum.* Annually, the Twin Metals Project would produce concentrates that contain 44,000 metric tons of copper, 10,000 metric tons of nickel, and 2,500 kilograms of palladium and platinum.

Copper, nickel and platinum group metals are essential to many industries, including power generation, electronics, aerospace, food processing, construction, automotive and healthcare.
