Homestake Mine

The Homestake Gold Mine in the northern Black Hills of South Dakota was the largest iron-formation-hosted gold deposit in the world and produced 1241.4 tons (or approximately 40 million ounces) of gold over its 125 year history at an average historical reserve grade of approximately 0.3 ounces gold per ton.

Tectonism and thermal activity associated with Trans-Hudson event occurred as a result of collision of Wyoming and Superior Cratonic Plates. Proterozoic gold metallization is interpreted to be a result of an evolved, long lived tecto-thermal process that relied on plate scale shear zones as fluid conduits and zones of high geothermal gradient as fluid mobilizers.

Gold ore bodies at the Homestake Mine were hosted within the Homestake Formation, consisting of siderite phyllite and/or grunerite schist, depending on the metamorphic grade. Individual ore bodies were contained within plunging synclinal fold structures of Homestake Formation known as ledges.

Dakota Territory’s Blind Gold Property is located in the productive structural corridor and approximately 4 miles northwest of the Homestake Gold Mine. Richard Bachman, President and CEO of Dakota Territory Resource Corp managed Homestake’s Black Hills exploration program of the 1980′s and 1990′s and was responsible for the drilling of diamond drill core holes that document Homestake iron-formation underlying the Blind Gold Property. Dakota Territory believes that the existence of Homestake iron-formation under the younger Phanerozoic-age rocks covering the Blind Gold Property presents a significant exploration opportunity in so much as the repeat of the Homestake style gold mineralization is not only possible, but has already been demonstrated to occur down plunge, just south of the Blind Gold Property.
