Workings of the Independence Mine are in the same-Shear zone as those of the Kentucky Derby, and mineralization is quite similar. The mine was opened as a crosscut tunnel which extends about 95 feet into the shear zone and cuts five sulphide enriched "veins". At the second vein, a distance of about 45 feet from the portal, a drift was driven some 25 feet to the southwest along the mineralized trend where it deviates to the south for nearly 50 feet before it again intersects the first "vein" encountered in the main crosscut. The drift then parallels this "vein" for another 45 feet. Gold, silver, and the platinum metals are all associated with the sulphides which occur as fracture and breccia fillings, pods, and small grains disseminated through tectonites. Available assay values range widely both as a function of sample source and assayer. Osterwald (1959, p. 75, and 135) lists the following values from "mine-run ore": 0.08 oz. gold, 0.22 oz. silver, 0.27 oz. platinum, 0.46 oz. iridium, 0.0302 oz. rhodium, and 0.1002 oz. osmium per ton of ore. NRRI tests on sulphide samples from the second "vein" failed to show any platinum group metals, but. 01 oz. gold and 0.8 oz. silver per ton and traces of copper and nickel were reported.
