Mule Mountains California. The mine is privately owned but is open to the public for a fee. With some hard work and effort, almost everyone leaves Opal Hill satisfied with the fiery agate they take with them. December 2017 and early 2018, Caleko is managing the mine and helping rockhounder find the fire agate.
Open May through September yearly. Roaring Camp was once a camp for Forty Niners, but since it was so inaccessible, most of the gold still remains. Visitors can see our operating gold mine and can mine their own gold by panning, sluicing, metal detecting, and dry washing.
