Point Location Description: Trenches on top of hill

Location Method: Field Visit with GPS

Access Description: An old over grown, mine access road leads directly to the Strathmore headframe. This road which has a gate, branches off the Chester Shannon mine access road. From the Strathmore, an overgrown exploration road extends southwest to the prospect. This road provides easy walking to the site.

Lithology Comments

Oct 17, 2013 (A Wilson) - The dominant rock type in the area is a massive coarse-grained hornblende diorite to quartz diorite. Locally within the diorite, there are irregular pegmatoid phases and the rock is also weakly altered to epidote over wide areas. Intruding the diorite is a number of small plugs of coarse grained, hornblende granodiorite. Other felsic rocks include thin felsite and pegmatite dikes. These dioritic phases are cut by a number of medium to fine grained diorite dikes which have been emplaced in a number of directions. These dikes are up to 3m wide and locally have highly irregular contacts. Lamprophyre dikes also occur and are typically associated with the tectonic shear zones, but are not common.

Mineralization Comments

Oct 17, 2013 (A Wilson) - Most of the mineralization is fine-grained chalcopyrite and pyrite disseminated in the matrix of the granodiorite and form up to 5% of the rock. The mineralization tends to be stronger where the granodiorite is cut by a shear zone. Some small quartz veins, up to 2 cm wide by 100cm long, occur within the sheared granodiorite. Outside of the granodiorite, some disseminated mineralization occurs as small splashes of iron staining along the strike of a small shear zone. When Murgold resampled the original trenches, only low gold values (up to 1 g/t Au) were obtained. Grab samples collected by the OGS in 1993 returned values of 1.02 g/t Au, 8.8 g/t Ag; 1.16 g/t Au, 8.9 g/t Ag.
