Metallic Mineral Occurrences of the Exposed Precambrian Shield in Northeastern Alberta, NTS 74E, L, M (GIS data, point features)

Author(s) Langenberg, C.W. Eccles, D.R. Date 2009-10-26

Alberta Geological Survey Bulletin 64 documents 190 metallic mineral occurrences. We have digitized these occurrences into GIS format as a point shapefile.

The description of these 190 metallic mineral occurrences on the exposed Precambrian Shield of northeast Alberta provides models for mineral deposition, establishes exploration targets and gives insights into the economic potential of the mineral showings. Commodities include gold, uranium, base metals and rare-earth elements. Among these occurrences, we have investigated 20 of them sufficiently, and they are of sufficient exploration importance to be classified as a mineral showing.
