Point Location Description: The B trench system 150m northwest of the main trench exposing the vein
Location Method: Field Visit with GPS
Access Description: The showing is 87km west southwest of Timmins and access is possible via Highway 101 to the Groundhog Lake - Horwood Lake access road / Highway 616. From this point a gravel road extends south for 11km to a landing on Horwood Lake. A 7km boat trip from the landing is then required to reach the east shore some 600m north of the showing which must be traversed.
1936 P.H. Silams initially staked the ground. Between this date and 1959 a series of trenches and pits had been dug over a 300m strike length but no records of this work exist. 1959 Kerr Addison optioned the property from J. Lefever and carried out a magnetic survey and short drill program. Grab samples returned up to 145 g/tonne gold and 23 g/tonne gold over 3cm in core from the veins. The vein was found to be series of discontinuous stringers. 1980 Raise Contracting and Ingamar Exploration over the next two years carried out a magnetic and VLF geophysical survey combined with a limited mapping program. 1986 Pelangio Larder Mines Ltd carried out an exploration program over the next three years which consisted of Magnetic, VLF-EM, and IP geophysical surveys, and a geological mapping program. This work found that the vein consists of a central quartz vein in chlorite carbonate sulphide schist. A maximum value of 30 g/tonne gold was returned in the schist associated with quartz carbonate stringers.

Dec 07, 2005 (S Fumerton) - The surrounding rocks consist of a northeasterly trending sequence of Fe tholeiitic metavolcanics. In the area the sequence is dominated by medium to coarse grained massive flows though there are intercalated horizons of fine grained flows, pillowed flows, and various tuffaceous rocks. The veins trend to the northwest and are hosted in a fine grained mafic flow with a series of subparallel anatomising chloritic shears within a metre of the veins.

Dec 07, 2005 (S Fumerton) - The Stack vein consists of a series of narrow quartz carbonate or fine grained cherty veins which are hosted in fine grained and medium grained mafic flows. At the northwest end (Trench B), the vein consists of a 15cm fine grained cherty quartz carbonate vein with a 4cm coarse quartz vein on the contact. Bleaching of the host rock extends 10cm from these veins and chloritic shears extend 2m. In the centre (Trench G) there are a number of quartz carbonate veins with abundant sulphides locally. One vein in this locality is up to 20cm thick.

Notes: There are a series of old trenches over a three hundred metre strike length. The northwestern trench has been cleaned out and series of sawn channel samples have been collected.
