The 25 leading districts have produced about half the gold mined in the United States, and the districts that are described account for roughly 90 to 95 percent. In general, gold is derived from three types of ore: (1) ore in which gold is the principal metal of value, (2) base- metal are which yields gold as a byproduet, and (3) placers/5(3).

Colorado mining history is a chronology of precious metal mining (e.g., mining for gold and silver), fuel extraction (e.g., mining for uranium and coal), building material quarrying (iron, gypsum, marble), and rare earth mining (titanium, tellurium).. The Uravan Mineral Belt (UMB) is on the west side of the state, and the Colorado Mineral Belt (COMB) is a large area of the state had gold. The lode gold deposits along this stretch are responsible for most of the gold production in the county, which has been reported to be million ounces (Koschmann and Bergendahl, ). Clark () placed the value of this production at $ million.
