1936: The property was held by the Dawn Red Lake Group and title to the claims lapsed prior to 1940. Some prospecting (trenching?) completed. 1940 (?): C. Harvey obtained the property. Prospecting, stripping of overburden and limited trenching. 1944: J.E.J. Fahlgren held the claim in the southwest corner of his #1 group. Prospecting, stripping and trenching were carried out on the adjoining claims. 1962: The claim was included in the west group of Martin McNeely Mines Ltd. One drill hole was completed by Martin McNeely Mines Ltd. 1969: Cochenour Exploration held the claim in its Balink group. An EM survey was completed by Cochenour Expl. 1970: Six diamond drill holes were completed. 1972: Horizontal loop EM survey completed by Cochenour Expl.

Dec 07, 2005 (K R Kettles) - GEOLOGICAL DESCRIPTION: The area around the occurrence is underlain by mafic metavolcanic flows and tuff-breccias. These units strike northeast-southwest and have nearly vertical dips. Pillow structures have been recognized and stratigraphic tops are to the northwest. Foliation is parallel to subparallel to the strike of rock units. The mafic flows are overlain by a sequence of conglomerate and greywacke beds. Quartz porphyry and quartz-feldspar porphyry dikes intrude into the volcanic rocks. The occurrence is located on the northwest flank of a NE-SW trending anticline. DEPOSIT DESCRIPTION: Gold mineralization occurs in a thin unit of highly silicified sedimentary rock, which contains narrow quartz veins and sulphide stringers. GEOPHYSICAL DATA: An EM conductor with moderate to strong magnitude has been located to the northwest of the claim, trending northeast-southwest.

Dec 07, 2005 (K R Kettles) - MDI1 DATA: GRADE 1970 DDH GS-70-3: 0.30 OPT AU OVER 45 CM (67.8-69.2 FT), AG NIL One of the diamond drill holes completed by Cochenour Exploration in 1970 intersected a 45 cm zone which returned an assay of 0.30 oz/ton (10.286 g/tonne) Au.
Dec 07, 2005 (K R Kettles) - From the drill core information, it appears that the host rocks have been highly silicified and weakly to moderately sericitized.
