Metals


Much of the CGS website is under heavy re-construction and will be for some time. The Publications area is working normally, but there is a lot of content from our original site that was in desperate need of updating. Please bear with us as we gather new information and rewrite hundreds of pages of material, gather and properly caption high-resolution images and otherwise bring you some very cool new and archival material never before seen! Stay in touch by subscribing to the >RockTalk< blog where we will announce new items periodically.


A metallic mineral has a distinctive, shiny, metallic luster. Metallic minerals such as gold and silver are also economic minerals. They are valued as beautiful collectible pieces and also for their widespread industrial use. The early history of the state of Colorado parallels the history of metal mining and is directly tied to the first significant and documented discovery of gold in the summer of 1858. A party of prospectors discovered placer gold in stream gravel at what is now downtown Denver, near the confluence of the Cherry Creek and South Platte Rivers (Auraria). This discovery led to the first Colorado gold rush. “Pike’s Peak or Bust” was emblazoned on many of the ox-drawn wagons carrying optimistic prospectors across the Great Plains to the Rocky Mountains of Colorado.

At various times throughout its history, Colorado has been the leading U.S. producer of gold, silver, molybdenum, lead, zinc, uranium, and tungsten. Other metals that have been mined in Colorado include copper, tin, vanadium, iron, beryllium, lithium, rare earth elements, thorium, tantalum, and manganese.
