Point Location Description: Cu symbol on ODM Map 2220
Location Method: Data Compilation
Access Description: The occurrence is reported to be located approximately 27 km west-southwest of Manitouwadge and 6.4 km east of Vein Lake (Milne 1968, P. Map 494; Milne et al. 1972, Map 2220). The area surrounding the occurrence is accessible via a well-maintained trapline trail which begins on the western shore of the Pic River opposite the Lower Landing road and continues westward to Vein Lake . Alternatively, the occurrence is accessible via float plane to a small unnamed lake located approximately 1 km south of the occurrence.
1966: Geological mapping; M.E. Coates (OGS). 1979: Regional lake sediment and water geochemical survey; GSC-MNR. Samples collected from lakes in the vicinity of the occurrence contained slightly anomalous amounts of Ni, but not Cu, Zn nor gold. 1989: Dighem airborne geophysical survey (MAG, EM, VLF-EM); Noranda Exploration Company Limited and Noranda Minerals Inc. (Geco Diovision). 1991-1992: Reconnaissance till sampling program; I.M. Kettles (GSC).

Terrane: Wawa-Abitibi
Belt: Manitouwadge-Hornepayne
Geological Age: Archean
Metamorphism Type: Regional
Metamorphism Grade: Amphibolite
Dec 07, 2005 (D McKay) - The occurrence is located in the Wawa Subprovince and is underlain primarily by a narrow (up to 1 km wide), north-easterly-trending belt of highly deformed and metamorphosed, locally migmatitic, mafic metavolcanic and metasedimentary rocks interpreted to represent the western extension of the Manitouwadge greenstone belt (Knight 1955; Coates 1970; Hawkins 1971: Kusins 1980). These metavolcanic and metasedimentary rocks are enclosed within granitic gneisses of the Black-Pic batholithic complex and have been intruded locally by dikes of quartz-feldspar pegmatite and diabase (Knight 1955; Coates 1970). The Little Joe Lake fault, a regional-scale, northwesterly-trending, dextral fault is located approximately 3.2 km south of the occurrence (Coates 1970, Map 2192). The Solann Lake fault, a regional-scale, north-northeasterly-trending fault is located approximately 4 km to the west (Coates 1970, Map 2192). The Labrador and Lloyd-Davis sulphide occurrences are located within the same belt of supracrustal rocks approximately 11 km to the northeast and 4 km to the southwest of the Vein Lake copper occurrence, respectively.
