The White Horse Flats Property consists of 92 mineral claims, covering approximately 1,900 acres, located 43 km (27 miles) south of Wendover, Nevada. The property is 13 km (8 miles) east of the Kinsley Mine, which produced approximately 400,000 ounces of gold from a Carlin-type deposit mined by Cominco in the mid-1980's. Subject to net smelter returns royalties, Columbus Gold controls a 100% interest in the property.

White Horse Flats covers three small hills and the surrounding pediment to the east. Exposures on the three hills are Devonian Guilmette Limestone, overlain by altered Mississippian Pilot Shale. Alteration in the Pilot Shale is weak to strong silicification with common liesegang banding. The altered section is thought to dip east under shallow gravel cover and the property is positioned to cover this target. Six initial samples of these altered rocks yielded anomalous gold (0.05-0.40 g/t) with highly anomalous arsenic, antimony, and mercury. This geochemical association is characteristic of the Carlin-type gold deposits of Nevada. Such deposits in Nevada hosted in the Pilot Shale, or stratigraphic equivalents, include the Alligator Ridge and Rain deposits, both of which produced 1,000,000 ounces of gold.
