Preliminary report on a uranium occurrence in the Atlanta area, Lincoln County, Nevada /

Surface and airborne prospecting of the Ely Springs dolomite is recommended in this region, especially near silicified breccia pipes.

Anomalous radioactivity was detected at a number of similar silicified breccia zones, including the Atlanta mine and several abandoned gold and silver workings in the Atlanta region.

The Blue Bird workings are in a silicified breccia pipe which contains quartzite fragments and silicified fragments of limestone and dolomite. Uraninite has been identified by X-ray methods in the silicified matrix of the rock. Three diamond drill holes on the property provided geologic information.

Uranium was discovered on the Blue Bird claims in the Atlanta area, Lincoln County, Nevada, in 1954. This deposit is situated approximately 35 air miles north of Pioche, Nevada. The geology of the area consists of moderately folded and highly block-faulted sedimentary rocks of Orodovician age. These sediments are overlain by the Tertiary volcanic rocks which have been disturbed by some of the faulting. Intrusive breccia pipes in the Ely Springs dolomite, the youngest of the Ordovician sedimentary rocks, have been silicified and mineralized and apparently controlled the localization of the gold, silver, and uranium minerals.
