A plan to extract metals from old mining waste in Leadville, Colorado, has sparked debate over its potential to help clean up contamination while raising concerns about environmental risks.
Matthew Brown, Brittany Peterson, and Thomas Peipert report for The Associated Press.
In short:
- CJK Milling wants to reprocess mine waste in Leadville, using cyanide to extract gold and other metals.
- Proponents argue the project will clean up pollution and boost the local economy, but critics fear it could revive water contamination.
- The EPA and local officials acknowledge the potential benefits but emphasize the need for proper oversight.
Key quote:
“The rub is they want to use cyanide, and whenever a community hears there’s cyanide or mercury they understandably get very concerned.”
— Ann Maest, geochemist who consults for environmental organizations including EarthWorks
Why this matters:
Mining waste has polluted Leadville’s waterways for over a century. While extracting valuable materials may aid in cleanup, improper handling could jeopardize water quality for residents, fish and wildlife.
