Silver 
 
Silver is currently produced in Colorado as a byproduct of gold mining at the Cripple Creek and Victor Mine and the Cash Mine.  The value of silver production is very small compared to that of gold because of the price differential between the two noble metals.  In 2007, the Cripple Creek and Victor Mines produced more than 89,000 ounces of silver worth $1,193,522.  The Cash Mine in Boulder County produced 4587 ounces in 2007.


Silver possesses the whitest color, the highest optical reflectivity and the highest thermal and electrical conductivity of all metals.  These properties give silver importance in such uses as mirrors, electrical and electronic components.  The primary industrial use of silver was formerly in photography because of the photosensitivity of silver halides.  The antibacterial characteristics of the metal are being exploited by the use of silver woven with fabric for odor-repellant clothing and antibacterial blankets for use by the military.  (To right: gold and silver vein in the Cash Mine, Boulder County)
