Exploration for Metallic Mineral Resources in MinnesotaGold

TheARCHEAN

SUPERIOR PROVINCEGREENSTONE BELTSHosting Significant Gold

Resource Potential in NorthernMinnesota

BACKGROUND

The Archean Superior Province greenstone belts that host many of Canada’s richest gold camps continue along strike across the U.S. border and into the north-ern portion of Minnesota. The potential for gold in Min-nesota’s portions of the Wawa and Wabigoon Subprov-inces is excellent, and the exploration models used for nearby gold deposits in Northwestern Ontario (e .g. New Gold, Hammond Reef, Moss Lake/Shebandowan), should be considered. Overburden thickness and compo-sition in Minnesota range from thin layers of glacial drift in the northeast, to saprolite buried under thicker layers of glacial deposits in the northcentral part of the State. The possibil ity of supergene enrichment within sapro-litic zones adds to the list of viable ore deposit models, and expands the area of viable greenstone belt gold ex-ploration.

HIGHLIGHTPreviously Unrecognized Area of High Gold Potential – In 2015 the DNR identif ied two areas with high bedrock gold potential within a portion of the Wawa Subprovince granite greenstone terrane (see T.61, R.14-15 on the map). Clusters of ti l l samples with high total and pris-tine+modified gold grain counts strongly suggest proximal gold-bearing bedrock source(s).
