Comments on the geologic information

  • Geologic Description = The deposit consists of sulfide-bearing carbonates, probably the Skajit Limestone (Nelson and Grybeck, 1980). More than forty, 1 to 5 cm bands of galena and sphalerite with copper and silver values were intersected in 122 m of diamond drill hole. There was considerable staking in the area and limited diamond drilling in 1976.
