Point Location Description: Shaft on KRL 7696 map 2074
Location Method: Data Compilation
Access Description: Underground access by drift on 1300 foot level from Cochenour Willans Mine.
1944: Marcus Gold Mines conducted a prospecting and trenching program. 1945: Marcus Gold Mines continued prospecting and trenching, and drilling began with two rigs. 1946: Marcus Gold Mines performed surface stripping and 72 drill holes totalling 3835.07 m. 1947: Shaft completed to a depth of 55.8 m with one level at 47.6 m. A total of 725.9 m of lateral underground work was completed. 38 underground drill holes were completed totalling 1830 m. Underground development ceased in November due to lack of encouraging results. 1950: Marcus Gold Mines drilled 14 DDH totalling 10,654 ft. 1952 Cochenour Willans Gold Mines Ltd. took an option on the Marcus claims and conducted a drill program of 19 DDH totalling 13,300 ft. 1953: Cochenour Willans drilled 9 DDH totalling 6,284 ft. 1954: Cochenour Marcus Gold Mines was formed to take over the property and drilled 3 DDH totalling 2626 ft. 1956: Name changed to Consolidated Marcus Gold Mines Ltd. 1959: Cochneour-Willans began exploration on the 1300 ft level to explore the underground potential of the Consolidated Marcus. The 14,253 ft drive on Consolidated Marcus was completed in 1963, however, ground conditions in a portion of this drift forced the termination of the exploratory drill program after only a very limited amount of work had been completed. 1981: Wilanour Resources Ltd. acquired the Marcus Property and undertook surface exploration focussed on the Wilmar and Consolidated Marcus properties, including linecutting, geophysics, geological mapping and drilled 14 DDH totalling 6949 ft. Dewatering of the underground workings was begun. 1984: Esso Minerals Canada optioned the property and conducted 21.2 miles of magnetometer surveying on the Wilanour and Marcus properties. 2001: Goldcorp conducted surface stripping, mapping and channel sampling.

Dec 07, 2005 (K R Kettles) - The shaft area of the Consolidated Marcus property is primarily underlain by pillowed mafic metavolcanic flows. The units strike approximately E-W and dip nearly vertically. Pillow structures indicated flow tops are to the south. Variable amounts of carbonate and quartz have been introduced into the flows. The southwestern extension of the East Bay Serpentinite underlies the area immediately NW of the shaft.

Dec 07, 2005 (K R Kettles) - A carbonate vein, with lenses of quartz and pyrite, was traced on surface over a distance of 150 m. The main vein varies from 5 to 10 cm in width, has a strike of N60 degs W and dips 40 degs SW. Two additional veins were encountered on the 45.75 m level. One section of the vein for a length of 21.4 m averaged 0.464 opt Au over a width of 1.2 m.
Jun 15, 2015 (A Lichtblau) - Au mineralization occurs primarilly in the thin (10 cm) quartz veins that cut altered basalt and are also found as tension veins in Fe-carbonate veins.
Mar 09, 2015 (Therese Pettigrew) - During the 1944 prospecting program, two quartz carbonate shear zones were located which contained small amounts of gold. One grab sample assayed 0.09 opt Au. The 1945 prospecting program found a quartz carbonate with stibnite that assayed 0.06 to 0.40 opt Au. In August 1945, gold was found in two trenches and samples assayed 0.35 opt and 0.59 opt Au.
Dec 07, 2005 (K R Kettles) - The mafic metavolcanic rocks have been silicified and carbonatized.
Jun 15, 2015 (A Lichtblau) - Alteration of the pillowed Balmer Assemblage basalt is dominantly Fe-carbonate
