resources in the Pacific Northwest: a contribution to the Interior Columbia 

Basin Ecosystem Management Project:  U.S. Geological Survey Open-File Report 

95-682, 425 p.



This report provides information on the potential for undiscovered metallic 

mineral resources in the interior Columbia River Basin area and surrounding 

areas of the Pacific Northwest for a U.S. Forest Service and Bureau of Land 

Management interagency project, the Interior Columbia Basin Ecosystem Management 

Project (ICBEMP). The area includes all of the states of Idaho and Washington, 

Oregon, and parts of California, Nevada, Utah, Wyoming, and Montana.  

Quantitative estimates of undiscovered metallic mineral resources (gold, 

silver, copper, lead, zinc, molybdenum, platinum group elements, and cobalt) 

are made for the interior Columbia River Basin area.  The report includes 

page-sized maps of tracts or areas that are permissive and favorable for 

the occurrence of 30 different metallic mineral deposit types.  Supporting data 

on the delineation of these permissive and favorable tracts, on past mine 

production, and on the rationales for the estimates of the number of 

undiscovered deposits are given.  



The report also describes the contents of a digital dataset (approximately 

12 MB) which consists of ARC/INFO Export format files and associated macro 

programs.  The dataset includes macro programs for creating ARC/INFO graphics 

files of the maps at a scale of 1:2,000,000. Instructions for obtaining the 

dataset over the Internet are provided in the report.

 

Requirements:  A networked computer system is required to copy the dataset 

from the host computer across the Internet.  A Geographic Information System 

capable of importing ARC/INFO Export format files is required for access to the 

digital files.  The digital dataset files are in UNIX ASCII format.
