Detailed geological mapping of the Hill Lake Area was undertaken to encourage exploration interest in, and to provide a mineral potentialevaluation and planning base for the area. Gold mineralization is commonwithin the Hill Lake Area and is associated with porphyry intrusions andfuchsite-carbonate schists. The Nipissing Diabase hosts carbonate-apatiteveins and dikes that contain silver and copper mineralization. Copper isalso found in shear zones.
