Red Hills Property







The Red Hills Property is located 56 km (35 miles) northeast of Ely in White Pine County, Nevada and covers the eastern portion of the Red Hills Mining District.


The project is 100% controlled by Columbus Gold, subject to underlying royalties.

The property is underlain by northerly striking, generally westerly dipping Cambrian through Ordovician sedimentary rocks which include (from oldest to youngest) the Windfall Formation, Pogonip Group carbonates (Goodwin, Ninemile and Antelope Valley Formations), Eureka Quartzite, Hanson Creek and Lone Mountain Dolomites.

Historical work and small scale mining at Red Hills identified lead, zinc, and silver breccia pipes and replacements in the Ordovician Pogonip Limestone, in particular near bodies of intrusive rock.

Twelve rotary drill holes, likely from the 1970's, have been identified on the property but no data is available and it is unknown who drilled them.

Columbus has completed geologic mapping, geochemical sampling, and a ground magnetic survey at Red Hills. Two zones of base and precious metal mineralization have been identified and mapped in the area. In the northern zone, silver, gold and base metal mineralization is hosted in Pogonip carbonates, Eureka Quartzite and in the Hanson Creek and Lone Mountain Dolomites along northerly and easterly trending breccia zones with local bleaching and calc-silicate alteration. Silver is the most significant metal in the area and averages of 124 g/t (3.6 opt) in those samples ≥ 34 g/t (1.0 opt) silver. A single high sample assayed 2,445 g/t (71.2 opt) silver. Gold averaged 0.86 g/t (0.025 opt) in those samples ≥ 0.34 g/t (0.01 opt) gold. Zinc and lead averaged 2.14% and 0.96% respectively in those samples ≥ 1,000 ppm. In the southern zone, mineralization that appears to be enriched relative to base metals (at the expense of precious metals) is confined to replacement and calc-silicate altered zones within the Pogonip Group Goodwin Limestone. Silver and gold values are of similar grade as the northern zone but are less abundant in number and extent. Significant, but erratic amounts of bismuth (up to 538 ppm), copper (up to 7.9%), and molybdenum (up to 350 ppm) are present.

In addition, sampling by Columbus restricted to the Nine Mile Member of the Pogonip has yielded numerous anomalous gold values ranging from 0.3 to 1.1 g/t (0.008 to 0.03 opt) gold, with little associated lead and zinc. The gold showings are in jasperoid and weakly silicified platy limestone and siltstone of the Nine Mile Member and could represent Carlin-type gold deposits distal to the lead-zinc mineralization.

The ground magnetic survey has identified several anomalies, interpreted to be buried intrusive rocks at depth. The base and precious metal anomalies are thought to be related to unexposed intrusive rocks present at depth. The mag survey indicates these bodies could be shallow in some places (less than 500 ft). The buried intrusive rocks present drill targets for porphyry copper/molybdenum, with the margins of the intrusives perspective for base and precious metal skarns and replacements.
