On October 14, 2021, the Division of Reclamation, Mining and Safety (DRMS/DIVISION) responded to the Dawson Gold Mine Permit Application submitted on June 20, 2021, by David Felderhof of Zephyr Gold USA Ltd. 

The decision date for the application is December 13, 2021. Mr. Felderhof has until then to satisfactorily address the concerns in the review or apply for an extension of the review period. If he does neither, then the Division will deny his application.

The original permit states that certain plans will be prepared upon approval of the application. The Division is requesting copies of the plans prior to approval.


Key areas of concern are blasting, mill design secondary containment, reagent storage, Grape Creek impact, protecting raptor nesting sites, spill prevention and control, environmental protection plan, hauling water from the contact water pond to the mill, stormwater management, exfiltration pond, construction schedule, stability analysis, interim Global Environmental Mine Services report, technical specifications, seepage from tailings, and riprap sizing for gradation.

Attached to the report was a copy of Colorado House Bill 19-1113, “Concerning the Protection of Water Quality from Adverse Impacts Caused by Mineral Mining,” approved on April 4, 2019.
