About the Tower Mountain gold property

The 100-per-cent-owned Tower Mountain gold property is located adjacent to the Trans-Canada Highway, approximately 40 kilometres (km) west of the international port city of Thunder Bay, Ont. The 2,500-hectare property surrounds the largest, exposed, intrusive complex in the eastern Shebandowan greenstone belt, where most known gold occurrences have been described as occurring either within, or proximal to, intrusive rocks. Gold at Tower Mountain is localized within extremely altered rocks surrounding the Tower Mountain intrusive complex, a multiphase, long-duration intrusive complex that control gold distribution on the property. Historical drilling has established anomalous gold extending out from the intrusive contact for over 500 metres along a 1,500-metre strike length, to depths of over 500 metres from surface. The remaining 75 per cetn of the perimeter surrounding the intrusion shows identical geology, alteration and geophysical response, offering a compelling exploration opportunity.
