Point Location Description: Roadside outcrop

Location Method: Field Visit with GPS

Access Description: The Husak Road No. 1 sulphide occurrence is located approximately 20 km north-northeast of Manitouwadge and 2.25 km east-southeast of Otter Lake. Recent logging operations have removed most of the trees in this area. As a consequence, the occurrence is well exposed and readily accessed. The occurrence is accessible via motor vehicle. From Manitouwadge, travel east and then north along the Camp 70 logging road for approximately 31.5 km to the Jim Lake road. Proceed north along the Jim Lake road for approximately 7.85 km to the Husak road. Proceed west along the Husak road for approximately 9 km. Sulphide mineralization is exposed on the surface of a small, low-lying outcrop located approximately 5 m south of the road.

Exploration History

1989: Lithogeochemical sampling; M. Smyk (OGS). Dighem 1989: Noranda Exploration Company Ltd. - airborne geophysical survey. 1991-1992: Reconnaissance till sampling survey; GSC. Samples collected in the vicinity of the occurrence contained unusually high amounts of Ni and slightly anomalous amounts of Au, Cu and Zn. 1990: K. Culhane - stripping, sampling. 1993: The occurrence was examined, but not sampled, by D.B. McKay for the OGS.

Geology Comments

Apr 14, 2014 (D McKay) - The Husak Road No. 1 sulphide occurrence is located within the Quetico Subprovince approximately 2.25 km north of the Quetico-Wawa subprovince boundary (Williams and Breaks 1990). The rocks in the vicinity of the occurrence are moderately to locally strongly foliated (100º/subvertical).

Lithology

Lithology Comments

Apr 14, 2014 (D McKay) - The paragneiss is generally light tan- to rusty-weathering, speckled black and white, medium- to coarse-grained, moderately foliated, non-magnetic and crudely laminated. The paragneiss is composed primarily of biotite, quartz and feldspar. Intrusion of granitic, tonalitic and pegmatitic material into the paragneiss has resulted in the development of localized lit-par-lit structures. Prominent-weathering, quartzofeldspathic layers within the migmatitic paragneiss locally contain minor 'S' folds (fold axes trend 260º and plunge 52º ). Small (30 by 50 cm), isolated, oval-shaped pods of coarse-grained, mafic amphibolite occur locally within the paragneiss. A narrow (25 cm wide), discontinuous, foliation-parallel iron formation is located approximately 10 m north of the occurrence.

Mineralization

Mineralization Comments

Dec 07, 2005 (D McKay) - The occurrence consists of fine- to medium-grained, subhedral, disseminated grains of pyrite, minor pyrrhotite, and rare chalcopyrite distributed erratically within migmatitic biotite-quartz-feldspar paragneiss. Isolated, coarse-grained, pyrite euhedra occur locally. The sulphides appear to be confined to a small (25 cm wide by 1 m long) area and could not be traced out along strike. A prominent, rusty gossan overlies the sulphide-mineralized zone. A grab sample of gossanous, pyritic, migmatitic paragneiss collected from the occurrence in 1989 by M. Smyk for the OGS returned assay values of nil Au, nil Ag, 1285 ppm Cu and 143 ppm Zn (Schnieders et al. 1990, p.150). Several similar sulphide occurrences (e.g. the Husak Road No. 2 and No. 3 sulphide occurrences) are located in the surrounding area. These occurrences also contain anomalous amounts of copper, and tend to be associated with amphibole-rich zones or pods within the migmatitic paragneiss. The economic potential of these occurrences is limited by their small size, erratic distribution and low metal content.
