1944: The property was held by MacBuck Red Lake Gold Mines Ltd. 1976: The property was held by Cochenour Willians Gold Mines. EXPLORATION AND DEVELOPMENT: Trenching and drilling on the MacBuck property were done from December 1944 to July 1945, and the surveying and geological mapping was started in September 1945 and completed by December of that year. core with VG assayed 30 opt Au, other DDH assays 0.47 opt Au/0.3ft, 0.23 opt Au/1.1 ft, 0.06 opt Au/ 1.2 ft, n trench 0.92m of iron formation assayed 0.10 opt Au In 1976, Cochenour Willians Gold Mines completed magnetometer or VLF-EM surveys, and three holes were drilled in 1978 totalling 416.5 m.

Dec 07, 2005 (K R Kettles) - GEOLOGICAL DESCRIPTION: The occurrence is underlain by a thin unit of interflow iron formation in a sequence of mafic flows. Rock units strike NE-SW and dip steeply to the NW. The mafic volcanics are generlly massive, but locally are highly sheared. Where highly sheared they are chloritic. A thin quartz porphyry sill or dike which is parallel to the strike of the units has been observed. DEPOSIT DESCRIPTION: A thin unit of interflow iron formation which occurs within altered and sheared mafic metavolcanic rocks is auriferous. The unit was exposed by trenching for 170.8 m along strike.

Dec 07, 2005 (K R Kettles) - MDI1 DATA: GRADE 1946 TRENCH AND DDH: SAMPLE ACROSS 0.92M OF IF ASSAYED 0.10 OPT AU; DDH:0.47/0.3',0.23/1.1',0.06/1.2', GRADE 1946 DDH: 0.03 M OF CORE WITH VG ASSAYED 30 OPT AU A sample taken across 0.92 m of iron formation returned an assay of 0.10 oz/ton (3.429 g/tonne)Au. Visible gold was seen in one piece of drill core, and this section assayed 30.0 oz/ton (1028.55 g/tonne)Au over 0.03 m.
Dec 07, 2005 (K R Kettles) - Where sheared, the mafic metavolcanic rocks have been chloritized.
