Idaho Wilderness Hearings

Statement:

Mr. Robbins. Senator, thank you for allowing me to testify at this hearing. My name is David Robbins of Spokane, Wash. I'm a resident geologist in the State of Idaho. Today I would like to present factual geologic data on area 1-141 and 1-664 which lay in Shoshone County northeast of Murray, Idaho. This data is being presented by myself with the permission of some of my clients, MINEXCO, Inc., and McGillivray-Neel and extracted from the U.S. Geological Survey GP Map 830 of which a copy is included in this presentation. 32-427 0—84 26 394 Both of these areas are on a Precambrian Basin which contains numerous significant mineral deposits and mines of gold, silver, lead, copper, and zinc. Both of these area are on the access of a major northwest trending fold structure. Many of the mineralized occurrences are associated with acid intrusive centers that are shown on the USGS map as high magnetic centers. Three of these which fall within the two wilderness review areas. Both the Prichard and Revillie formations are exposed in these areas. And both of these formations or their respective equivalents are known to contain major stratographic mineral occurrences in the United States and Canada. Both of these areas contain old mines and small number of production. Both of these areas have a significant number of unpatented lode claims owned by both small and major mining companies, which are presently being explored. In the south central part of Unit 1-141, MINEXCO, Inc., through the use of geology, geophysics, and geochemistry, has defined a northwest trending favorable area that is about 5,000 feet long and 500 to 2,500 feet wide. Therefore, I ask you to review both of these areas that have mines and roads and a high potential for mineral deposits. Thank you.
