From the Introduction:
The section on Mineral Deposits includes descriptions of the mining districts of Lake County. Lake County boasts two of the most important mining districts in Colorado, the Leadville district and the Climax district. These two districts have played major roles in the history and economic development of the state. Other mining districts of lesser economic importance are also described, as well as areas of potential industrial mineral and construction material deposits.
There is no record of any oil and gas drilling in Lake County. There are no recorded geothermal sites in Lake County, nor any formations known to host coal deposits. No new field investigations of mining districts were made in the course of this study. The appendix of this report contains transcriptions of mineral and mine descriptions from the two important U.S. Geological Survey Professional Papers on the Leadville district. The CGS has chosen to preserve these descriptions as originally written.
