Dec 07, 2005 (K R Kettles) - The Cole gold Mines Main Showing shaft area is underlain by felsic flows and tuffs interlayered with gabbroic sills. The volcanic rocks contain about 12 parallel shear zones ranging in width from 15 cm to 3 m and containing lenses and veins of bluish-grey quartz. The shearing is oriented roughly parallel to bedding and dips 65 degs to 75 degs north. Gold is in both the quartz veins and wallrock. Quartz veining occurs over a length of 440 m, in underground drilling and workings. Single quartz veins are as long as 213 m. Several west-dipping, left handed faults in the shaft area have laterally offset the veins about 34 m. Kerr Addison concluded that magnetic and EM anomalies in this area are caused by disseminated magnetite in basic to ultrabasic rocks of the Pipestone Bay stock.

Dec 07, 2005 (K R Kettles) - The Cole Gold Mines Main Showing consists of a number of mineralized shear zones in the felsic volcanics. The zones are about 425 m long. Gold is contained in both quartz veins and wallrock next to the veins. Gold values occur over a width of 0.6 to 2.5 m, and visible gold has been noted to a depth of 365 m. Shearing is roughly parallel to bedding and dips steeply to the N. The quartz veins hosting much of the gold pinch and swell along strike. The highest gold values occur in sphalerite and chalcopyrite bearing vein sections. A 700 lb. sample from the 621 m level assayed 1.32 opt Au and 0.61 opt Ag. 2021: Rockland resources released results from a diamond drill hole program. Results include 4.9 g/t Au over 0.5 m and 3.6 g/t au over 2.5 m from RL-CP-02, 3.0 g/t Au over 0.5 m from RL-CP-04 (Rockland Resources, news release, March 31, 2022).
Dec 07, 2005 (K R Kettles) - The wallrocks are silicified and contain quite a lot of sulphide minerals.
