Abstract

This report and database compiles virtually all publically available drill hole location data, lithological logging data, copper-nickel assay data, and rock quality data for about 2,145 exploration drill holes in and near the Keweenawan Duluth Complex in northeastern Minnesota. This database covers about 1,779,600 feet of drilling over about 70,000 lithological, and about 70,000 separate assay intervals. All of this drilling is in St. Louis, Lake, and Cook counties. The digital data are presented in an industry standard (Gemcom for Windows) exploration and mine modeling software format, as well as spreadsheet and comma-delimited files for use in other programs. This format can be adapted for use in a GIS program such as ArcView. The purpose of this report is to make these data available to mineral exploration companies in a format almost immediately usable by them.
