Comments on the location information

  • This modern-era (1980s-1990s) exploration project is located 4 - 5 miles southwest of Canon City, and 3-4 miles south of Royal Gorge. The area of mining claims stretches east-west for several miles. The eastern part is on the northeastern slopes of Dawson Mountain. The western part is near Grape Creek. The project area encompasses the Copper King Mine, the Dawson Mountain-Surprise Group, and several other prospects in the Grape Creek area.

Comments on the commodity information

  • Private exploration reports indicate a minimum of 339,000 tons of mineralized material grading 0.3 to 0.4 ounces per ton gold. Data donated by Sunshine Mining Company to Colorado Geological Survey. Copper and other base metals were not quantified, but samples indicate grades of over 5 percent locally.

Alteration

  • (Local) sulfide mineralization

Economic information

Comments on the geologic information

  • Variably thick sulfide mineralization hosted by metasedimentary and volcanic rocks. The deposit strikes generally east-west and dips steeply to the south. The mineralized layers display a contorted map pattern due to post-mineralization folding during the metamorphic event which occured in the Early Proterozoic. Private reports on file at the Colorado Geological Survey indicate that gold-copper mineralization dominates in the eastern part of the project area, while zinc and lead dominate in the western area.

Economic information about the deposit and operations

Development status Prospect
Commodity type Metallic

Mining district

District name Grape Creek/Greenhorn District

Comments on the reserve resource information

  • One report estimates 339,000 tons grading 0.3 to 0.4 ounces per ton. Copper and other base metal resources are not formally quantified. Reports indicate that base metal mineralization increases to the west relative to gold. Base metal grades of over 5 percent are reported in some areas. Several private reports on the district are on file at Colorado Geological Survey.
