Dec 07, 2005 (C Papertzian) - An open cut, measuring 130 feet long in a north-south direction, 20 feet wide, and 30 feet deep, exposes a narrow band of hematite-bearing carbonate rock. The carbonate lens is in contact with a rhyolite on the west side. The east contact was not seen. Some magnetite is present. Red hematite is formed by the alteration of magnetite-bearing ferruginous carbonate rock. Another pit occurs 600 feet to the south.
