Public Comments Due February 2, 2026
CJK Milling Company, LLC, proposes to reopen the Leadville Mill. They would disturb old piles of already mitigated mining materials, transport them by large trucks through Leadville's historic downtown, and use a disruptive milling process. The Colorado Division of Reclamation, Mining and Safety (DRMS), the state regulatory agency responsible for reviewing the CJK permit application, is now accepting public comments, including objections to this very concerning proposed plan.
If you feel as strongly as we do, ACT NOW. Submit your objection asap but no later than the February 2, 2026 DEADLINE. Submitting an objection is easy and takes just minutes to do. Here's how:
Access the DRMS Permitting Action Comment/ Objection webpage https://dnrlaserfiche.state.co.us/Forms/DRMS_Comment
Only fill in the required fields noted by a red asterisk *
Use Permit Number: M1990057
Enter "Lake" in the county field
Enter your objections into the Description of Comment or Objection field
You can upload a document that contains your comments / objections as well.
Comments can be long or short, reflect your chief concerns or be a list of many areas you find problematic and concerning. You can copy or adapt the sample objections (below) or simply read for ideas and inspiration. Note that water, environmental contamination and safety issues are of major concern to DRMS.
The following samples can be copied and pasted into the DRMS form. Please modify the statements or craft your own statements to reflect your sentiment and concerns.
Water Focused Objection
The impact on the upper Arkansas River basin and particularly the Leadville area is significant. Impacts include potential chemical contamination of surface and groundwater. The mill waste pile will be a potential source of water contamination risks forever, yet the mill plan does not address perpetual monitoring and management of the waste pile. High water consumption may reduce water availability in the Leadville area for residential and other uses. These water issues alone are so significant the mill should not be permitted to operate.
Broad Objection
I object to this application on numerous grounds: disturbance of and transport of tailings from East Side of Leadville to Mill site; no foolproof method to guarantee no leakage of chemicals from proposed dry tailings landfill of processed materials; no plan to manage the bulk of the processed waste, threat of leakage into water table of chemicals into groundwater, affecting wells, fishing/rafting industry, irrigation water; potential of environmental catastrophe from leakage of toxic substances (e.g. via air, water) resulting in extreme adverse effects to County residents, visitors and the tourist economies of Lake County and neighboring counties; destruction of wildlife habitats and death of animals, fish in Lake County and beyond along the length of the Arkansas River; health risks associated with airborne toxic particulates ("fugitive dust").
Arkansas River Impact Objection
Over the past several decades, countless hours of work and millions of dollars have been spent on repairing the devastating impacts of historic mining in Lake County on the Upper Arkansas River and its tributaries, particularly in the California Gulch watershed where the Leadville Mill and much of the targeted waste is located. As a result, the Upper Arkansas is now the longest continuous stretch of Gold Medal water in the nation.
I would ask DRMS to consider if the risks of this project to the Leadville community and the surrounding environment are worth the benefits. Of particular note, we would ask DRMS to carefully consider the following:
Does the CJK proposal adequately identify groundwater depth throughout the site or the preferential flow pathways/rates? In the instance of a spill, it would be necessary to have groundwater defined. Groundwater mapping would also play into a remediation plan in the instance of a spill. Those pathways must be identified and mitigated during an emergency to reduce impacts on drinking water supplies including wells in the area.
Has CJK properly addressed the disposal of processed waste throughout the life of the mine? Where will processed waste be disposed of or remediated to reduce impacts on human health and the environment? Does the life cycle of the proposed disposal plan fully mitigate the risks of its location in a highly sensitive environment?
Does the CJK proposal address the risks to the community and the environment of disturbing the east side waste piles? The potential for release of toxic materials into the air, surface water, and groundwater must be addressed both during and after excavation. These waste piles have stabilized over time and disturbing them will increase the potential for erosion of freshly exposed surfaces by wind and water.
After you have done the above, please ...
