Group of Mines


A group of precious opal lode mining claims known as the Little Pebble, Phantam, Peacock #s 2-4, Royal Peacock #s 1-2, Northern Lights, and April Fool Millsite.

Originally discovered about 1911. Originally owned by Rhinehart & Archevaletta in the 1920's to 1930's. Relocated by Flora Loughead ("Lockheed") and Mark Foster in 1937. Acquired by the Wilson family around 1942 as a "toss-in" for purchasing the April Fool fluorescent opal claims.

It has been operated as a commercially productive opal mine and fee dig for many decades. Many large and valuable gem and specimen opals have been recovered from this mine.
