Point Location Description: Vertical projection of vein centre transferred from company plans to OBM 1:20,000 map
Location Method: Data Compilation
Access Description: The showing is 91km west southwest of Timmins and easy access is possible via Highway 101 to the Horwood Lake road which extends south 11km from the Highway to the landing at Horwood Lake. From the landing it is another 11km boat trip to the east where the showing is located.
1918 Tom Jessop staked the original claim covering the showing. 1927 Nipissing Mining optioned the property, stripped off the overburden exposing a vein 0.6 x 30m which was pitted and sampled, and reportedly returned high gold values. 1928 Showing flooded was when Horwood Lake was damned, 1934 Groundhog Gold Mines purchased the property. 1935 Hollinger Consolidated optioned the ground and over the next two years carried out a small drill program apparently with negative results. 1947 Groundhog Gold Mines carried out a magnetic survey, mapped the property and drilled a number of holes. However, the company was unable to locate any additional auriferous veins. 1984 Ultrex Petroleum carried out over a two year period a geological mapping, a magnetic, VLF-EM, and IP geophysical surveys followed by a diamond drill program. This work was done on ground to the east and south of the Groundhog showing and was unsuccessful in locating any gold mineralization but did locate a lens of massive sulphides with chalcopyrite 1989 Tarzan Gold carried out a reconnaissance mapping and prospecting program on the ground surrounding the Groundhog showing.

Dec 07, 2005 (S Fumerton) - The old plans on file show a shear zone parallel to, and immediately west of, the mineralized quartz vein.

Dec 07, 2005 (S Fumerton) - The surrounding rocks consist of a sequence of Fe tholeiitic flows, fine grained, coarse grained, and pillowed which trend to the northwest in the immediate area. Further afield the volcanic rocks generally trend to the northeast.

Dec 07, 2005 (S Fumerton) - The mineralisation is confined to a single vein system that trends northwest parallel to stratigraphy in the adjacent rocks. The main vein consists of grey quartz with chloritic inclusions and is well mineralized with chalcopyrite, pyrite, and pyrrhotite located within fractures within the vein. Adjacent to the main vein is a narrow zone of bleached volcanics or zones of sheared chloritic material with some quartz stringers. Five metre spaced channel samples taken by Nipissing Mining Co over a 30m length averaged 18 g/t gold across an average width of 0.6m.

Notes: Two days were spent in the Groundhog camp examining company plans and drill core in order to obtain a description of the vein. [ PRECIS ]
