The Gold Cloud Project consists of 100% Redstar-owned unpatented mining claims covering sediment-hosted (Carlin-type) gold mineralization along a range-front fault about 17 miles south of Barrick's Ruby Hill gold mining operations in the Eureka Mining District. The Project lies along the southeastern part of the Cortez gold belt.
Gold Cloud contains an extensive zone of carbonate veins and silicification (jasperoids) within Devonian limestone. The zone is exposed for a strike length of 6,800 feet (2km) following a northeast-trending range-front fault. Anomalous gold (>0.1 ppm) and favorable trace elements occur along at least 2,300 feet of this strike length within quartz-veined jasperoids and hematitic carbonate veins, with values obtained by Redstar reaching 2.80 ppm gold (0.082 opt), 2.6 ppm Hg, 527 ppm Sb and 351 ppm As. The valley-fill sediments (pediment) beyond the range-front fault appear to be thin, based on relatively detailed gravity data as well as the occurrence of north-northwest-trending outcrops of limestone outboard of the range front. The project lies along the northeast side of a distinctive feature in the regional geophysical gravity data which coincides with the Cortez gold belt and extends north-northwest for least 70 miles from the Gold Cloud area through the Gold Bar and Tonkin Springs gold districts and the world-class Pipeline-Cortez Hills gold district.
During gold mineralization in these types of deposits, the limestones are dissolved or decalcified, and the calcium carbonate is then remobilized to overlying and peripheral areas. Therefore, the exposed carbonate vein system, the silicification and favorable geochemistry could be the uppermost or distal portion of a large Carlin-type gold system yet to be identified, either beneath the exposed veins or outboard of the range front under pediment cover. Rare native sulfur in jasperoid also indicates a distal setting.
