Point Location Description: Stripped outcrop

Location Method: Field Visit

Access Description: The Camp 54 Road sulphide occurrence is located in Nickle Township approximately 13 km east-northeast of Manitouwadge and 800 m south-southwest of the southern end of Lorne Lake. The occurrence is accessible via motor vehicle followed by travel on foot. From Manitouwadge, proceed east and then northeasterly along the Camp 70 logging road for approximately 12.5 km to the Camp 54 road. Proceed southwest along the Camp 54 road for approximately 350 m. Quartz vein-hosted sulphide mineralization is exposed on the north end of a small ridge approximately 100 m east of the road.

Exploration History

1967: Geological mapping; J.F. Giguere (ODM). 1978: Regional lake sediment and water geochemical survey; GSC-MNR. Samples collected from lakes in the vicinity of the occurrence contained slightly anomalous amounts of gold and base metals. 1989: Geological mapping; H. Williams and F. Breaks (OGS). Dighem airborne geophysical survey (MAG, EM, VLF-EM); Noranda Exploration Company, Limited and Noranda Minerals Inc. (Geco Division). 1991: Reconnaissance till sampling program; I.M. Kettles (GSC). Samples collected in the vicinity of the occurrence contained moderately anomalous amounts of gold and base metals. 1992: Lithogeochemical sampling; D.B. McKay (OGS).

Geology Comments

Dec 07, 2005 (D McKay) - The deposit is located within the Wawa subprovince and is underlain primarily by coarse-grained, moderately foliated (250 degrees /70 degrees N), highly fractured, granodioritic gneiss of the Black- Pic batholith (Giguere 1972, Map 2219; Williams and Breaks 1990; Zaleski and Peterson 1993). Supracrustal rocks comprising the south limb of the Manitouwadge synform are located approximately 1 km to the north (Williams and Breaks 1990; Zaleski and Peterson 1993). A regional-scale, northwest-trending fault, termed the Lorne Creek fault, is located approximately 500 m northeast of the occurrence (Giguere 1972, Map 2219). Several other north- and northeast-trending faults occur in the surrounding area (Giguere 1972, Map 2219; Milne et al. 1972, Map 2220). Several northwest-trending diabase dikes have intruded the granodioritic gneiss in the vicinity of the occurrence (Giguere 1972, Map 2219). Early exploration in the vicinity of the occurrence indicated the geology was not favourable for hosting economic gold nor base metal mineralization. As a consequence, little subsequent work has been conducted in the area. The supracrustal rocks located approximately 1 km to the north, however, have been the focus of continued base metal exploration since the early 1950s.

Lithology

Lithology Comments

Dec 07, 2005 (D McKay) - The occurrence consists of medium- to coarse-grained pyrite hosted within highly fractured, locally hematized and epidotized, coarse-grained, moderately foliated, non-magnetic, granodioritic gneiss.

Mineralization

Mineralization Comments

Dec 07, 2005 (D McKay) - The pyrite occurs as disseminated grains, locallized patches, isolated euhedra and late-stage fracture fillings associated with quartz and epidote. The pyrite generally constitutes less than 1% of the gneiss, but concentrations of up to 2 to 3 % occur locally. Several small areas in the vicinity of the occurrence have been stripped of overburden. Narrow (2 to 5 mm wide), variably spaced, foliation-parallel and crosscutting, pyritic quartz veins are exposed in most of these stripped areas. These veins appear to be relatively common in the area surrounding the occurrence. No base metal-bearing sulphides were observed. This occurrence is considered to have no economic potential. A grab sample collected from the occurrence in 1992 by D.B. McKay for the OGS returned assay values of trace Au, 13 ppm Cu and 42 ppm Zn.
