Comments on the geologic information

  • Geologic Description = Anomalous gold and arsenic values in rocks and soils define two north-trending parallel zones 500 to 600 feet wide, several thousand feet long, and approximately 600 feet apart. Pyrite mineralization occurs in silicified breccia and fault zones. Gold values in the easternmost deposit (Propalof zone) reach 0.035 ounce per ton, and in the westernmost deposit (Ring vein) they reach 0.037 ounce per ton (Ellis and Apel, 1990). Three drill holes had scattered intervals grading 0.1 to 1.2 ppm gold. At a depth of 160 feet, a drill hole on the Propalof zone cut 109 feet grading 0.28 ppm gold (includes 11 feet grading 0.035 ounce per ton) in silicified and quartz-veined rock. The rocks at the prospect are part of the Eocene to Oligocene Popof volcanic rocks (Wilson and others, 1995).
  • Age = Eocene or younger.

Mining district

District name Alaska Peninsula

Comments on the workings information

  • Workings / Exploration = In 1990 Battle Mountain Exploration Company mapped the prospect, collected rock, soil, and power auger samples, cut three trenches for a total of 1,420 feet, and drilled three core holes for a total of 1,211 feet. One drill hole intersected 11 feet grading as high as 0.035 ounce of gold per ton.
