Geology

The property is underlain by a bimodal suite of mid-Miocene volcanic rocks composed of basalt and rhyolite. Large, through-going, northerly, northwesterly and northeasterly structures form a complex zone of extensional tectonics with resulting horst and graben blocks. An area approximately 5 miles long and 2.5 miles wide, lying within the property, has been variably altered by shallow level hydrothermal solutions. Argillic alteration is the most widespread throughout the property, but silicification and propylitic alteration are also present. Gold and silver mineralization is hosted in banded quartz veins as well as in sheared gouge zones. (Jan25/05)
