Gold Bar Complex

The Gold Bar Complex is located south of the Tonkin Complex on the continuation of the Cortez Trend.

Exploration drilling at the Gold Bar Complex in 2011 totaled approximately 7,245 feet (2,208 meters) in 41 reverse circulation drill holes that were focused on extensions to the Gold Pick-Gold Ridge and Cabin Creek mineralization, as well as targets found by geologic mapping and sampling.

The Gold Pick-Gold Ridge area occurs on the Battle Mountain-Eureka mineral belt in a window of lower-plate carbonate rocks surrounded by upper-plate rocks. The lower-plate carbonates at Gold Pick-Gold Ridge consist of an east-dipping section of Silurian Lone Mountain Dolomite, Devonian McColley Canyon Formation, Devonian Denay Formation, and Devonian Devils Gate Limestone. Northwest-trending and northeast-trending structures cut the area; the Gold Pick mineralization is localized in an apparent northwest-trending horst of McColley Canyon Formation, which is cut by a series of northeast-trending structures.

The Limo Property is located in east-central Nevada. The Limo Property position totals approximately 44.5 square miles (115 square kilometers). Gold mineralization has been identified in numerous places along the 15 mile (24 kilometers) length of the property. Exploration drilling at the Limo Property in 2011 totaled approximately 59,157 ft. (18,031 meters) in 10 diamond drill core holes and 70 reverse circulation drill holes. The drilling was focused on two targets, Cadillac and Continental, outside the existing mineralization.
