The Malachite copper and chrysocolla prospect consists of one patented mining claim covering approximately 20.4 acres, located 1.6 miles west of the town of Mason in the southern portion of the Yerington District, Lyon County, Nevada.
In 2003, the Company completed a diamond drill program for a total of 581 feet (177 metres) distributed in 5 holes. The five drillholes were laid out along the contacts between the limestone of Mason Valley and lower andesitic to dacitic tuff unit beginning from an adit into the Malachite structure. The drillhole M–1 apparently missed the structure entirely, due to a roll in the structure, consequently the drillhole M–2 was then located on the same pad in order to intersect the structure. Hole M-1 was not assayed and M–2 showed only minor mineralization: the highest Copper (“Cu”) value was returned from interval 44.0–44.8 that ran 4400 parts per million (“ppm”) (0.44%) Cu. The southernmost drillhole, M–3, (N 70 W, -45o) also showed only minor mineralization: 0.43% Cu (0 – 1.5 ft), 0.235% Cu (37.5 – 39.0 ft) and 0.162% Cu (228.7 – 230.4 ft). This drillhole was the deepest, and encountered intrusive dikes mainly between 170 and 175 feet, and also between 203 and 215 feet. Brecciated, intrusive textures were also apparent. Samples from these intervals showed little mineralization. Drillholes M–4 and M–5 were drilled from the same drill pad and yielded the most spectacular results. In Hole M–4, a vertical drillhole, weathering and oxidation was intersected to a depth of 38 feet, with spotty copper oxides and some malachite. Between 38 and 51.2 feet, the host rock was a weathered, dolomitized limestone, well recrystallized with no apparent bedding. The mineralization apparently occurs mainly along the fractures, and is an oxidized sulphide (chalcocite?). Secondary malachite and chrysocolla occur sporadically throughout the core. The best average results obtained were 1.51%Cu over 14.4 feet and 2.13% Cu over 13.9 feet in Hole M-4; 2.38% Cu over 7.5 feet and 1.31% Cu over 12.2 feet in Hole M-5.
The Malachite Report suggests a two-phase program be carried out consisting of a first phase preliminary exploration program with data tracking, assembly review of previous work, geoscientific compilation; replotting and reinterpretation of previous work using GEMCOM software package; geological mapping, prospection and sampling; drill site preparation including road access and drill rig platforms ground geophysical surveys (Mag and EM); complementary diamond drilling on the best targets generated by the compilation, the geophysics and recent drilling. Phase 2 would consist of advance exploration and definition and supplementary drilling if warranted following Phase 1.
