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.

|Younger tuffaceous sedimentary rocks|
Age: Neogene (2.588 - 23.03 Ma)
Description: Tuffaceous and other young Tertiary sedimentary rocks. Most of these rocks are sedimentary with a strong volcanic component - a few are tuffaceous with a strong sedimentary component. This unit includes rocks originally mapped as the High Rock sequence in Washoe County; the Horse Camp Formation in northern Nye County; the Esmeralda Formation in Mineral and Esmeralda Counties; older lake beds in Lincoln County; the Belted Range Tuff; the Indian Trail Formation (now abandoned); Timber Mountain, Paintbrush, and Crater Flat Tuffs; Wahmonie and Salyer Formations in southern Nye County; the Siebert Tuff in Esmeralda County; the Muddy Creek Formation in Clark County; and the Thousand Creek and Virgin Valley “beds” in Humboldt County; and other unnamed units. It corresponds to units Ts3 and Tts from the 1978 State map. It is present in all counties.
