National Mining Association reports that copper hits another record as tariff expectations and rising demand put supply in focus.

America’s mining industry supplies the essential materials necessary for nearly every sector of our economy – from technology and healthcare to energy, transportation, infrastructure and national security. The National Mining Association (NMA) is the only national trade organization that serves as the voice of U.S. mining and the hundreds of thousands of American workers it employs before Congress, the federal agencies, the judiciary and the media, advocating for public policies that will help America fully and responsibly utilize its vast natural resources. We work to ensure America has secure and reliable supply chains, abundant and affordable energy, and the American-sourced materials necessary for U.S. manufacturing and economic security, all delivered under world-leading environmental, safety and labor standards. Headquartered in Washington, D.C., the NMA has a membership of more than 250 companies and organizations involved in every aspect of mining, from producers and equipment makers to service providers.
