Utah-Clipper Project, Lander County, Nevada

The Utah Clipper Property is located adjacent to Barrick Gold’s multi-million ounce Pipeline-Gold Acres gold mine complex, in the Cortez-Pipeline sector of the Battle Mountain Gold Trend, Nevada. The project totals 16 patents and 170 unpatented mining claims.

The Pipeline and Gold Acres mines are operated by Barrick Gold. Barrick also owns the nearby Cortez Hills gold deposit discovered in 2003, which hosts reserves of more than 10 million ounces of gold. Barrick recently announced significant new discoveries about 6 km (3.7 miles) and 8 km (5 miles) southeast of Cortez Hills, known as Goldrush and Four Mile. An inferred gold resource of 15.7 million ounces has been reported at the developing Goldrush area.

Past work includes modern exploration by Phelps Dodge, Amax, Kennecott, Homestake, Newmont, US Borax, Goldfields, Noranda/Hemlo, Uranerz, Agnico-Eagle, Barrick Gold.  Drilling was completed from 1992 to 2013. The drilling is wide spaced leaving much of the property unexplored.

The Utah Clipper Property covers a portion of the Roberts Mountain thrust with metamorphosed lower plate limestone and limey siltstone in the footwall of the thrust.  The principal geologic targets at Utah Clipper are as follows;

  • Vein and disseminated silver-lead-zinc deposits in upper plate rocks.
  • high grade structurally controlled gold deposits in skarn in “lower plate” carbonates
  • Classic “Carlin” style bulk mineable, disseminated gold deposits

The surface rock exposures at Utah Clipper are Ordovician and Silurian siliceous shales, cherts, and sandstones in the upper-plate of the Roberts Mountain Thrust Fault. Favorable lower-plate carbonate rocks, are encountered in drilling, and are interpreted as the Devonian Wenban and Silurian Roberts Mountains Formations. Both these carbonate formations are known to host major Carlin-type, gold mineralization in northeast Nevada, and are the host rocks to much of the gold mineralization at the Pipeline, Cortez, and Cortez Hills deposits located near the Utah Clipper Project. Felsic to intermediate intrusive rocks, of Jurassic to Tertiary-age, cut all the older sedimentary rocks. Intrusive bodies are exposed on the property, in the nearby Gold Acres Mine pit, at the nearby Robertson Project and at Bullion Mountain.

The shallow silver mineralization is hosted in veins, stockworks and disseminated in wide structures that occur in the upper-plate, siliceous formations. Small historical production of silver and base metals is recorded from the Boss Mine and silver production is recorded from the Utah Camp and Clipper mines, all located within the claim boundary. Highlights include 25 feet grading 0.052 opt gold, 50 feet grading 6% combined lead-zinc, 5 opt silver and 0.012 opt gold in skarn, and anomalous silver-lead-zinc mineralization throughout the top 100 meters of the silver zone.

The near surface oxide silver-lead-zinc zone has been identified in soil and rock sampling over a length of 3.2 km and a width of 0.6 km. Drilling by US Borax and others in this area included intercepts of up to 12 opt Ag, 3% zinc and 5% lead over 10 feet.  Significant intercepts of 100 feet of 2 opt silver, and 2% combined lead and zinc are present in 17 of 26 wide spaced holes. The holes are roughly 400 feet apart.  Other holes along this trend are 2 to 3 kilometers apart.  Potential for 10 to 30 million tons grading 2 to 3 opt silver (66 to 100 g/t) exists within the drill area.  Upside could be over 100 million tons based on the above.
