[ SOLUTIONS ]Unlocking America’s Past to Build Its Future
For more than a century, U.S. mining operations powered a growing nation — and left behind billions of pounds of copper-rich tailings. Today, Quincy Materials is transforming this mining legacy into a modern solution for American industry and infrastructure.
Our Mission
Transform legacy mining tailings into high-purity copper and construction materials — creating skilled jobs, protecting the environment, and strengthening U.S. infrastructure.
OUR SOLUTIONS
Copper and Supplementary Cementitious Materials (SCMs) are foundational to America’s future — from electrification and defense to resilient industry and infrastructure.
With our partners, Quincy Materials is advancing large-scale remediation and resource-recovery projects that deliver:
Domestic copper supply for industry, infrastructure, and national defense
SCMs to support durable construction
Shoreline cleanup and long-term environmental restoration
Skilled employment and economic revitalization in former mining communities
[ SOLUTIONS ]A National Opportunity:
Copper and Supplementary Cementitious Materials (SCMs) are critical to America’s clean-energy transition and future development. Quincy Materials is advancing large-scale beneficiation, remediation and resource recovery projects that deliver:
Domestic copper supply for technology and defense
Low-carbon SCMs to support resilient infrastructure

The Quincy Materials Advantage
The US Midwest contains an estimated 200–400 billion pounds of copper-laden stamp sands — one of the largest legacy tailings deposits in North America.
By responsibly reprocessing these materials, Quincy Materials can:
Recover million of pounds of domestic copper
Produce an economic alternative to carbon-intensive Portland cement
Remediate Great Lakes shorelines impacted for generations
This unique convergence of scale, infrastructure access, and mining heritage positions the region as a cornerstone of America’s materials future.
