Exploration History

1939: Mr. Scott prospecting on behalf of Lake Shore Mines carried out a stripping and trenching program centred on a quartz vein north of this prospect. Reportedly some gold was panned from the vein in the Jessup Group. 1949: Jess-Mac GML carried out an exploration program at the east end of Opeepeesway Lake. The program consisted of a magnetometer survey, trenching and 21 holes were diamond drilled. In the following year a number of stratigraphic holes were drilled from the ice. 1961: Jess-Mac GML resumed exploration in the area with a small diamond drill program which intersected some disseminated chalcopyrite which constitutes this prospect. No assay values were reported. 1961: Worthington Mines continued exploration in the area with a small drill program. Most of the work was directed towards an area to the west but some drilling was done at this prospect. 1966: Rio Tinto optioned the property and carried out a magnetic and electromagnetic survey which failed to give any encouragement. 1971: Falconbridge Nickel carried out VL electromagnetic, and magnetic, which covered the prospect. This work indicated that a number of conductors parallel to north east and northwest trending shears were probably intersected in the earlier drilling. Falconbridge's follow-up drilling was confined to anomalies in Osway Township. 1981: Osway Exploration carried out a magnetic and VLF electromagnetic survey which covered the prospect. Follow-up work in the next year consisted of trenching plus diamond drilling west of the prospect. 2007-2010: Augen Gold Corp.: performed an electromagnetic, aeromagnetic and radiometric surveys ;prospecting and sampling; EM, IP, Mag, GC, Samp.

Geology Comments

Dec 07, 2005 (S Fumerton) - Small crenulation folds occur in the schistosity.

Lithology

Lithology Comments

Jul 01, 2016 (S Fumerton) - The mineralization is hosted in a porphyry which ranges in colour from grey to red. The rocks exposed in the area are highly schistose, sericitic carbonate felsic rocks. It is difficult to determine if the original rock was an intrusive or a conglomerate but probably the former.

Mineralization

Mineralization Comments

Dec 07, 2005 (S Fumerton) - At the striped area there are abundant angular quartz vein material up to 30cm across. In these quartz fragments there are sinuous trails (folded ?) containing chlorite and chalcopyrite.

Dec 07, 2005 (A Wilson) - The drill log for Gaffney DDH 5 reports 18.5 feet of grey porphyry containing copper pyrite.
