Colorado is where I started my love affair with gold. I used to take my 3″ dredge up to Tarryall Creek every weekend in the late 70’s early 80’s. Colorado is know as the Silver State, but it also ranks second among the gold producing states. Over 40 million ounces has been produced in Colorado. Most of the mines are in the mountainous western half of the state. The most important sources of gold is from Telluride type ores. For more information contact Colorado Division of Mines or the Colorado School of mines.
