About CMA
Advancing innovation, policy, and progress across Colorado’s mining industry.
Who We Are
Welcome to the Heart of Western Mining
Founded in 1876, the Colorado Mining Association (CMA) has been a trusted voice for the mining industry for nearly 150 years.
As the oldest mining industry association in the U.S., CMA unites a diverse group of members, including producers, exploration companies, processors, equipment suppliers, engineers and consultants, law firms, financial institutions, and mining companies with national and global headquarters in Colorado.
A Message from Our President
I'm honored and excited to lead the Nation’s oldest professional mining trade association in my home state of Colorado at a pivotal time for our industry. Mining is the front end of the supply chain for every major industry in the country and plays a vital role in supporting Colorado's economy. From affordable energy to national defense, emerging technology and clean energy development and storage, so many facets of Colorado's economy and future goals depend on a robust mining industry.
The Colorado Mining Association has played a leading role in Colorado’s business, legislative, and legal environment since our state’s founding and is well positioned to continue its leadership role as we enter the new minerals economy. I’m optimistic about the future of mining in Colorado and the West and I look forward to continuing to work with CMA’s members to support the world-class operations in our state and partner with the broad range of communities, elected officials, and minerals-reliant sectors to grow our industry and meet the rapidly increasing need for responsibly sourced minerals.
