Location and accuracy The Red Quartz prospect is centered about 1.3 mile northwest of the south tip of Woewodski Island at an elevation of about 500 feet. It is about 0.2 mile northwest of the center of section 1, T. 62 S., R. 29 E. The location is accurate.

Geologic setting

Geologic description

The Red Quartz prospect was discovered in 2005 and was explored in 2006 by Bravo Ventures Group (2207). Distinctly reddish quartz veins occur in float, rubble, and outcrop for about 300 meters in heavy vegetation. Thirteen of the 30 samples that were collected contain more than 1 gram of gold per ton; the best contained 3.8 grams of gold per ton. Eight of the 30 contained 7.8 to 91.3 grams of silver per ton with notable arsenic and antimony values. The mineralization is distinctly different from the massive sulfide mineralization in Brushy Creek just to the south (PE033) and suggests epithermal gold-silver mineralization of a type that has not previously been found on Woewodski Island.
As mapped by Karl and others (1999), the rocks in the area are part of the Triassic Hyd Group which consists of greenstone, pillow breccia, and volcanic breccia, with tuff, limestone, chert, conglomerate, sandstone, and argillite. A Cretaceous diorite stock is nearby.
