Centered about the “Town of Calico“, The Calico Mining District, which had a peak population of 3,000, produced between $13 and $20 million in silver and $9 million in borate minerals between 1881 and 1907. On April 6, 1881, several claims were located that formed the largest mine in the district, the Silver Queen. Profitable mining of silver in the area ceased in 1896.
