The Chert Cliff Property is located in the Gold Bar District about 40 miles northwest of Eureka, Eureka County, Nevada. Gold Bar, including the property area, occurs within the southern section of the productive Battle Mountain Trend of gold deposits.

Subject to third party net smelter royalties, the Chert Cliff Property is 100% controlled by Columbus and has been leased to privately held Platte River Gold Inc. for a term of 20 years. Annual lease payments progressively increase from USD$5,000 to USD$8,500.

Geology of the claims area consists of dolomitic siltstones of the Mississippian Webb formation overriding massive Devonian limestones in thrust fault contact. Disseminated gold occurs in hydrothermally altered Webb siltstones and jasperoid.

Gold was discovered at Chert Cliff in the mid 1960's during the initial wave of prospecting for carbonate-hosted gold deposits following recognition of the Carlin model in 1961. The most intensive work was carried out by Asarco in the 1980's and succeeded in outlining the Chert Cliff gold deposit with a historical resource of 1.4 million tons grading 0.04 ounces gold per ton (56,000 ounces). This historic resource is not NI 43-101 compliant and a qualified person has not done sufficient work to classify these historic estimates as a current mineral resource. They should not be relied upon and Columbus Gold does not treat them as current mineral resources.

Anomalous to ore grade intercepts were also encountered in isolated drill holes north and east of the resource area but were never followed up.

Platt River Gold commenced drilling on the property in July 2008, and as reported by Platte River Gold, the drill program includes four Reverse Circulation (RC) drill holes for a combined planned depth of 4,100ft (1250 m) with target depths between 450 ft (140 m) and 1,500 ft (450 m) for each hole.
