Point Location Description: Diamond drill hole
Location Method: Conversion from MDI
Access Description: Point Located: A point 2.25 km south and 2.05 km east of the northwest corner of Elliott Township. The Cameron occurrence is a few hundred metres (600 m according to Jensen 1978) north of Ghost Lake near the west shore of a small creek which drains Ghost Lake to the north. Access to the occurrence area is from Highway 101 east of Matheson via sand and dirt roads and an overgrown trail which must be traversed by foot (as indicated by Jensen 1971).
1925: Gledhill (1925) reported that a pit exposed pyritic rhyolite intruded by lamprophyre dikes. 1939: Claims in the area were known as the Cameron-Godfrey group and what was described as well mineralized 'syenite' was exposed by three trenches. 1946: C.L. Gibson (of Hollinger Consolidated Gold Mines Ltd.?) examined the occurrence, at this time known as the Cameron occurrence. Sylvanite Gold Mines Ltd. optioned claims from G. Cameron, sampled, and obtained assays as high as 0.16 ounce of gold per ton from old trenches in the area. Erie Canadian Mines Ltd. diamond drilled 3 holes totalling 304.5 feet near the old trenches. 1949: In a letter to N. Hogg dated April 13, 1949, M.C. Gardiner reported that pyritic rhyolite near trenches at the Cameron occurrence had yielded assays as high as 0.21 ounce of gold per ton. 1962: I. Stairs restaked the Cameron occurrence and H. Hansen mapped the area geologically. Samples of pyrite and quartz stringer material are reported to have assayed from 0.005 to 0.10 ounce of gold per ton, with the highest gold tenors apparently associated with samples containing elevated pyrite contents. 1980: T. Randa, of Cochrane, restaked the Cameron occurrence and E.D. Frey mapped the area geologically. 1988: Union Mining Corp. held claims on which the Cameron occurrence is located and overburden stripped. Visible gold was noted to occur in 'syenite' near its contact with chert.

Dec 07, 2005 (C Salo) - Geological mapping (Jensen 1982, 1978, 1971; Jensen and Langford 1985; Jensen and Baker 1986; Johnstone and Steele 1989; Baker et al. 1982; McClenaghan et al. 1988, 1987; Steele 1988; assessment files, Resident Geologist's Office, Kirkland Lake) indicates that the occurrence area is underlain mainly by largely glacial drift covered east northeast striking, steeply south dipping, and south facing weakly metamorphosed (greenschist or lower metamorphic facies) massive and pillowed tholeiitic basalt and volumetrically minor intercalated rhyolite and interflow sediment of the (Archean) Kinojevis Group. The occurrence is on the north limb of the east striking and east plunging Blake River Synclinorium. Intrusive rocks in the area include a small (tens of metres in size) medium grained 'syenitic' body (classified by Jensen (1978) as an albite syenodiorite) and biotite lamprophyre dikes.

Dec 07, 2005 (C Salo) - Jensen (1978) summarized the known gold mineralization at the occurrence as follows: 'Assays from the X-ray diamond-drill holes drilled by G. Cameron indicate gold occurs mainly in finely pyritized rhyolite. The best assay was 0.034 ounce of gold per ton over a length of 10.6 m (35 feet), (Resident Geologist's Files, Ontario Ministry of Natural Resources, Kirkland Lake). 'Diamond-drill hole samples taken by Sylvanite Gold Mines Limited from the dike of syenodiorite gave an assay of 0.01 ounce of gold per ton over a length of 1.5 m (5 feet). Surface samples of the syenodiorite are reported to range from nil to 0.22 ounce of gold per ton over a width of 0.9 m (3 feet), (Resident Geologist's Files, Ontario Ministry of Natural Resources, Kirkland Lake).' (p.59)Gold mineralization at the Cameron occurrence occurs within locally pyritic rhyolite and within a small felsic and locally pyritic albite syenodiorite body which intrudes the rhyolite. The rhyolite horizon coincides with a band of low magnetic response which may be traced continuously for thousands of metres (OGS 1984). Analogous gold mineralization is known to be associated with similar rhyolitic material elsewhere in the Harker-Holloway Township area (i.e. at the Harker Gold deposit, the Iris Gold deposit, the Coin Lake occurrence, and the Meridian occurrence) and with sodic felsic syenitic intrusive rocks elsewhere in the area (i.e. at the Harker Gold deposit and the Iris Gold deposit). Chalcopyrite and hematite (specularite) occur within rhyolite northeast of the occurrence and visible gold has been observed within 'syenite' in the area (assessment files).Analyses*:
