Geological Age: Archean
Metamorphism Grade: Greenschist
Dec 07, 2005 (C Salo) - Geological mapping (Sutcliffe and Steele 1989; Gupta and Johnstone 1987; Jensen and Langford 1985; Pyke 1980, 1976; Berry 1942; McClenaghan et al. 1989, 1988, 1987; Steele 1988; Richard and McClenaghan 1985) indicates that most bedrock in the occurrence area is glacial drift covered. Bedrock consists mainly of weakly metamorphosed (greenschist or lower metamorphic grade) subaqueously deposited tholeiitic volcanic rocks and interflow sedimentary rocks of the (Archean) Kinojevis Group. The basement supracrustal rocks strike east northeast, dip steeply, face south, and occupy part of the north limb of the east striking and east plunging Blake River Synclinorium. Intrusive rocks in the area include large felsic bodies, northeast striking diabase dikes of the (Proterozoic) Abitibi and/or Preissac swarms, and generally north striking diabase dikes of the (Proterozoic according to Heaman 1989) Matachewan swarm. Several regional scale south southeast striking faults have been interpreted to occur in the area. A recent geophysical survey of Sheraton Township (OGS 1984) detected several bedrock conductors in the occurrence area.

Dec 07, 2005 (A Wilson) - Diamond drilling intersected a sequence of rhyolite, rhyolitic tuff and breccia intruded by feldspar porphyry dikes. Two sections containing massive pyrite returned low gold values.

Dec 07, 2005 (A Wilson) - A 12.5 ft section of Selco's core returned an assay of 0.01 oz/t Au; a 3.9 ft section of drill core returned an assay of 0.01 oz/t Au. The best assay returned from the Cross Lake core was 1.73% Zn, 0.6% Cu over 1.3 m.
Dec 07, 2005 (C Salo) - Selco Exploration Co. diamond drill hole no. 9 is reported (assessment files, Resident Geologist's Office, Timmins) to have yielded within felsic volcanic and fragmental rocks 12.5 and 3.9 foot sections of nearly massive pyrite mineralization. Both sections assayed 0.01 ounce of gold per ton.
