Darkstar

Summary

The Darkstar deposit is located approximately one mile east of the Pinon Main zone deposit in Elko County, Nevada. Darkstar is a near surface, open pit gold/silver system. The Darkstar structural trend mineralization and alteration have affected rocks of the Mississippian and the Chainman Formations and those of the upper Miocene Humboldt Formation. The deposit alteration is characterized as multi-phased silicification and clay alteration associated with this gold/silver system. The property development area has a defined antiformal shaped zone that is somewhat bedding conformable gold mineralization. This zone is characterized by abundant hydrothermal injection breccias and pervasive silicification. Mineralization occurs sporadically in the weakly silicified hanging and footwall rocks and, also hosted by crosscutting and high angle fault zones.

Preliminary metallurgical testing results on drill cuttings indicate that mineralization is amenable to direct cyanidation treatment indicate gold recoveries in leaching. Gold recovery rates were fairly rapid and extraction and was substantially. Cyanide consumption was low.
