Dec 07, 2005 (C Salo) - Geological mapping (Sutcliffe and Steele 1989; Johnstone and Steele 1989; Johnstone 1987, 1986; Johnstone and Trowell 1985, 1984; Arndt 1986, 1977, 1975; Arndt et al. 1977; Coad 1976; Satterly 1952; Steele 1988; McClenaghan et al. 1989, 1988, 1987; Vagners 1984) indicates that bedrock in the area consists mainly of weakly metamorphosed (greenschist or lower metamorphic grade) subaqueously deposited felsic to ultramafic volcanic and intrusive rocks of the (Archean) Stoughton- Roquemaure Group which strike east southeast, dip steeply, face south, and occupy part of the north limb of the southeast striking and northwest plunging McCool Hill Syncline. Narrow (tens of metres in width) north striking diabase dikes of the (Proterozoic according to Heaman 1989) Matachewan swarm intrude the Stoughton-Roquemaure Group rocks in the area. Recent geophysical surveys of Munro Township (OGS 1984; assessment files, Resident Geologist's Office, Kirkland Lake) have delineated an anomalous bedrock conductor which coincides with the location of the occurrence.

Dec 07, 2005 (C Salo) - Diamond drilling on or near claim no. 53321 (the southeast quarter of the north half of lot 6, concession VI, Munro Township) at an unspecified date by the Dyman Prospecting Syndicate (hole nos. SB-1, SB-2, and SB-3, totalling 894.5 feet) is reported (assessment files) to have intersected variably calcite altered graphitic rhyolite hosting massive and disseminated chalcopyrite and sulfide mineralization. This drilling is reported (assessment files) to have yielded copper assays as high as 4.9% and cobalt assays as high as 0.27%. The sulfide mineralization sampled by the drilling is likely from the same or a stratigraphically closely related sulfidic horizon which occurs about 850 m west northwest of the occurrence at the Potterdoal deposit (described elsewhere in this compendium). Shklanka (1969) reported that pits excavated in rhyolite within claim no. 53314 (the northeast quarter of the north half of lot 6 concession VI, Munro Township) also explored pyrite and chalcopyrite mineralization, but no assays from this area are provided by him.
