A company in Leadville wants to truck 1.2 million tons of the waste to a mill on the southwestern edge of the high mountain city, use cyanide to extract gold and silver from the rocks, and then return the hills to a more natural state. CJK Milling says its proposed operation would be “one of the largest, most innovative environmental cleanups of abandoned mine waste” in Leadville — and a model for other historic mining areas.
But the company’s proposal has prompted skepticism and alarm in Leadville, with some locals opposing the additional trucks the project would put on roads in the area. Others fear the use of toxic cyanide — up to 600 pounds a day — so close to town and the Arkansas River. They worry about the project’s potential impacts on soil, water and air quality.
The proposal has also raised a broader question: What is the future of mining in a town that once relied on it but has cultivated a new identity as a high-altitude hub for tourism and recreation?

Company leaders, however, say their project is not a mining operation — and instead is focused on removing the waste piles and returning the land they sit on to its natural state. The project could be an example of profitable, privately funded cleanup of mining waste, said Nick Michael of CJK Milling.
