Little Joe Mine
The Little Joe and Hoss Opal Mines are located in the Calico Hills and discovered by Ray Duffield in the 1960's[1]. The Royal Rainbow Opal Mine is located a few km to the north.
In the 1970's the mine was owned by Ray and Marge Duffield, who charged diggers $5 per day with the condition that they would sell a larger find to them for $600 maximum.[2]
