Point Location Description: Roadside outcrop
Location Method: Field Visit with GPS
Access Description: The Husak Road No. 2 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 located approximately 10 m north of the Husak Road No. 1 sulphide occurrence. 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. Sulphides are exposed on the surface of a flat, low-lying outcrop located approximately 5 m north of the road.
1965: Geological mapping; M.E. Coates (ODM). 1978-1979: Regional lake sediment and water geochemical survey; GSC-MNR. Samples collected from lakes in the vicinity of the occurrence contained slightly anomalous amounts of base metals. 1989: Geological mapping; H. Williams and F. Breaks (OGS). Lithogeochemical sampling; M. Smyk (OGS). Dighem airborne geophysical survey (EM, MAG, VLF-EM); Noranda Exploration Company, Limited and Noranda Minerals Inc. (Geco Division). 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. 1993: Lithogeochemical sampling; D.B. McKay (OGS).

Province: Superior
Subprovince: Quetico
Geological Age: Archean
Metamorphism Type: Regional
Metamorphism Grade: Granulite
Apr 14, 2014 (D McKay) - The Husak Road No. 2 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 (100 degrees/subvertical). Mineral assemblages indicate the rocks have experienced upper amphibolite and locally granulite facies-grade regional metamorphism (Williams and Breaks 1990). An east-trending, regional scale, linear topographic feature referred to as the Little Nama Lake lineament (Coates 1968, Map 2141) is located approximately 400 m north of the occurrence.
| Rock Type | Rank | Composition | Texture | Relationship | Magnetite Ironstone | 1 | Magnetic | Host |
|---|---|---|---|---|
| Paragneiss | 2 | Biotite-Quartz- Feldspar | Migmatitic | Near |
| Amphibolite | 3 | Coarse-Grained Pods | Near |
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 260 º and plunge 52 º). Small (30 by 50 cm), isolated, oval-shaped pods of coarse-grained, mafic amphibolite occur locally within the paragneiss. Sulphides occur primarily within a narrow (25 cm wide), discontinuous, foliation-parallel unit within the paragneiss. This unit may be a strongly deformed and metamorphosed lean iron formation.

Apr 14, 2014 (D McKay) - The occurrence consists of 1 to 2% fine- to medium-grained, subhedral, disseminated grains of pyrite, minor pyrrhotite, and rare chalcopyrite distributed erratically within a narrow (25 cm wide), locally strongly magnetic, foliation-parallel iron formation. The iron formation can be traced along strike for approximately 8 m. The sulphides appear to be associated with mafic, amphibole-rich zones within the unit. Prominent, rusty gossans overlie the sulphide-rich portions of the iron formation. Trace amounts of medium- to coarse-grained, subhedral to euhedral pyrite occur as disseminated grains within the surrounding migmatitic paragneiss. Several similar sulphide occurrences (e.g. the Husak Road No. 1 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. A grab sample of gossanous, coarse-grained, amphibole-rich gneiss collected from the occurrence in 1989 by M. Smyk for the OGS returned assay values of 27 ppb Au, <2 ppm Ag, 1700 ppm Cu, 211 ppm Zn, <10 ppm Pb, <1 ppb Pt and 1 ppb Pd. Grab samples collected from the occurrence by prospector K. Culhane in 1990 returned assay values of up to 0.06% Cu, 0.06% Zn, 0.01 ounce Ag per ton, and 0.02 ounce Au per ton. A grab sample of rusty-weathering, dark gray, moderately foliated, coarse-grained, locally strongly magnetic, amphibole-rich, iron formation containing 2 to 3% sulphides (pyrite, pyrrhotite and trace chalcopyrite) collected from the occurrence in 1993 by D.B. McKay for the OGS returned assay values of 3300 ppm Cu, 211 ppm Zn, <0.1 ounce Ag per ton and <0.01 ounce Au per ton.
