Dawson Gold Project

The Dawson Gold Project is a zinc, gold, copper, and lead mine located in Fremont county, Colorado.

About the MRDS Data:

All mine locations were obtained from the USGS Mineral Resources Data System. The locations and other information in this database have not been verified for accuracy. It should be assumed that all mines are on private property.

Satelite View

MRDS mine locations are often very general, and in some cases are incorrect. Some mine remains have been covered or removed by modern industrial activity or by development of things like housing. The satellite view offers a quick glimpse as to whether the MRDS location corresponds to visible mine remains.

Comments

Comment (Location): 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.

Comment (Geology): 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.

Comment (Reserve-Resource): 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.

Comment (Commodity): 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.
