Topographic profile and geologic cross-section across the Big Ten mineral trend at Amsel. Alteration and gold mineralization at Amsel is hosted in a rhyolite volcanic succession near the contact with crystalline basement at the western margin of the 27 million year old Big Ten Tertiary volcanic caldera. Shown is the unexplored target at Amsel of disseminated gold below the gold-bearing alteration lithocap.
