Location Method: Field Visit with GPS
Access Description: The Husak Road No. 3 sulphide occurrence is located approximately 19.5 km north-northeast of Manitouwadge and 1.85 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 400 m west of the Husak Road No. 1 and No. 2 sulphide occurrences. 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 9.4 km to an unnamed tertiary logging road. Proceed north along this unnamed road for approximately 75 m. Sulphide mineralization is exposed in several large, angular blocks of rock blasted out of a trench located approximately 10 m east of the road.
1989: Lithogeochemical sampling; M. Smyk (OGS). 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.

Province: Superior
Subprovince: Quetico
Geological Age: Archean
Metamorphism Type: Regional
Metamorphism Grade: Granulite
Apr 14, 2014 (D McKay) - The Husak Road No. 3 sulphide occurrence is located within the Quetico Subprovince approximately 2.25 km north of the Quetico-Wawa subprovince boundary. The rocks in the vicinity of the occurrence are moderately to locally strongly foliated (095 º/subvertical). Mineral assemblages indicate the rocks have experienced upper amphibolite and locally granulite facies-grade regional metamorphism. An east-trending, regional scale, linear topographic feature referred to as the Little Nama Lake lineament is located approximately 400 m north of the occurrence.

Apr 14, 2014 (D McKay) - The occurrence is underlain primarily by an east-trending sequence of locally schistose, migmatitic paragneiss. 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. Small (30 by 50 cm), isolated, oval-shaped pods of coarse-grained, mafic amphibolite occur locally within the paragneiss. Sulphide mineralization in the vicinity of the occurrence is associated primarily with these mafic pods which may represent a strongly deformed and locally disrupted silicate-rich iron formation. The sulphide mineralization is best exposed in several large angular boulders surrounding a 12 m long by 1 m wide by 0.3 m deep blast trench emplaced in 1990 by prospector K. Culhane.

Apr 14, 2014 (D McKay) - Several small, isolated, rusty gossans occur widely distributed in the general area surrounding the blast trench. These gossans are underlain by migmatitic paragneiss containing less than 1% sulphides, primarily pyrite, as fine- to medium-grained, disseminated, anhedral grains and rare, coarse-grained euhedra. The sulphides in the blocks blasted out the trench are associated primarily with small (up to 15 cm wide by 50 cm long), mafic pods hosted within migmatitic, biotite-quartz-feldspar paragneiss. The pods appear to be confined to an area approximately 4 m long by 2 m wide. The pods are composed primarily of coarse-grained, dark green amphibole and rare, rounded inclusions and patches of glassy quartz. Medium- to coarse-grained, black, magnetite euhedra constitute up to 5% of each pod. Pyrite, pyrrhotite, and rare chalcopyrite constitute up to 25% of each pod and occur as fine-grained, disseminated grains, small (up to 1 cm across), fine-grained, irregularly shaped patches, and isolated, coarse-grained euhedra. These pods are compositionally similar to the silicate-rich portions of the iron formations which host the Otter Lake, Lovlien, and Little Nama Lake sulphide occurrences located along strike to the west. The possibility exists that the Husak Road No. 3 sulphide occurrence is hosted in a strongly deformed, locally disrupted, silicate-rich, iron formation. The economic potential of the occurrence is limited by its small size, lack of continuity, 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 11 ppb Au, <2 ppm Ag, 1500 ppm Cu, and 315 ppm Zn. A grab sample of rusty-weathering, dark green, coarse-grained, moderately magnetic, pyrite-rich amphibolite collected from the occurrence in 1993 by D.B. McKay for the OGS returned assay values of <0.01 ounce Au per ton, <0.1 ounce Ag per ton, 1700 ppm Cu, and 168.50 ppm Zn.
