Dec 07, 2005 (A Mitchell) - The Berrigan occurrence is located within the north half of lot 12, Con. III, Hislop Twp. Bedrock here is largely drift covered, poorly exposed, and bedrock exposures are essentially confined to the southwest quarter of the north half of lot 12, concession III (Baker et. al., 1980; McvClenaghan et. al. 1988, 1987; Steele 1988). According to Prest (1953), bedrock exposures consist of massive intermediate volcanic rock and reddish weathering white feldspar phyric rock. A pyritic shear with unspecified orientation is reported by Prest to be deveoped in the volcanic rocks and to be pitted, byt no assays from these pits are reported by him. Jensen (1989, 1985) and Trowell (1985), and Troop (1989) indicate that the volcanic rocks are weakly metamorphosed (greenschist or lower metamorphic facies) belong to the (Archean) Stoughton-Roquemaure Group, and are east southeast striking, steeply dipping, and south facing. The area is also indicated by these authors to be spatially associated with the Porcupine-Destor Fault Zone. The Hollinger Consolidated Gold Mines diamond drilling outlined an east striking lenticular body of pink to purple syenite which is locally porphyritic and which intrudes intermediate, felsic and pyroclastic volcanic rocks. Reports in the assessment files, Resident Geologist's Office, Kirkland Lake, indicated that Hollinger Consolidated Gold Mines drill hole no. 1025 yielded a 24 foot intersection of 0.02 OPT Au and that drill hole no. 1034 yielded a 6 foot intersection of 0.10 OPT Au.
