Location Method: Field Visit

Access Description: The Qued QT-09 zinc occurrence is located approximately 31.5 km south-southeast of Manitouwadge, 2.25 km south of the south end of Dead Otter Lake and 1.35 km north-northeast of the north end of Musher Lake. The Hemlo gold deposit is located approximately 18 km to the southwest.The occurrence is accessible via motor vehicle followed by travel on foot. From Manitouwadge, proceed south along Highway 614 for approximately 40 km to the Twist Lake road. Proceed northeast along the Twist Lake road for approximately 7.7 km to where a north-trending line (L 3+00W) of a grid cut by Placer Dome Inc. in 1992 crosses the road. Proceed north along this line for approximately 100 m to the vicinity of a trench (QT-09) dug by Qued Resources Limited in 1984. Zinc- and copper-bearing sulphides are exposed in several locations within the southern section of this trench.

Geology Comments

Dec 07, 2005 (D McKay) - The Qued QT-09 zinc occurrence is located in the Wawa Subprovince approximately 18 km northeast of the Hemlo mines. The area surrounding the occurrence is underlain primarily by an east-southeasterly-trending sequence of mafic to felsic metavolcanic and lesser metasedimentary rocks which comprise a portion of the the north limb of the Schreiber-Hemlo greenstone belt (Milne 1968, Map 2147; Siragusa 1985, Map P.2738). In the vicinity of the occurrence, emplacement of the Dotted Lake Batholith has folded the belt into a large easterly-plunging anticline (Milne 1968, Map 2147). The occurrence is located along the south limb of this structure. The supracrustal rocks in this area are locally strongly foliated (100 degrees to 115 /85 degrees SW) and mineral assemblages indicate they have experienced lower amphibolite facies-grade regional metamorphism (Milne 1968). In the vicinity of the occurrence, the supracrustal sequence is approximately 3.5 km wide and is bounded to the north and south by granodioritic rocks of the Dotted Lake Batholith and the Musher Lake Pluton, respectively (Milne 1968, Map 2147). The northern portion of the belt is dominated by massive to pillowed basalts which are overlain to the south by intermediate to felsic pyroclastic rocks containing minor metasedimentary interbeds (Milne 1968; Cavey and Dumouchel 1985). The supracrustal sequence dips steeply to the southwest and has been interpreted to young in the same direction (Milne 1968; Cavey and Dumouchel 1985). The occurrence is located near the southern boundary of the belt approximately 900 m north of the contact with the Musher Lake Pluton. In the vicinity of the occurrence, 3 parallel, east-southeast-trending, interflow metasedimentary units (iron formations) have been recognized (Cavey and Dumouchel 1985). The occurrence is located in the southernmost of these iron formations.

Lithology

Lithology Comments

Dec 07, 2005 (D McKay) - The mafic metavolcanic rocks are locally pillowed flow units which are typically rusty-weathering, dark gray-green, fine- to medium-grained, weakly to moderately foliated (100 degrees /82 degrees SW), non-calcareous and locally moderately to strongly magnetic. Pyrrhotite and pyrite generally constitute 1% of these amphibole-rich rocks and occur as fine- to medium-grained, disseminated grains. The iron formation is 2.5 m thick, banded and locally sericitic. This unit contains up to 10% fine- to coarse-grained, pyrite, pyrrhotite, chalcopyrite and sphalerite as disseminated grains, irregularly shaped patches and narrow (1 to 2 mm wide), foliation-parallel laminae and discontinuous veinlets.

Mineralization

Mineralization Comments

Dec 07, 2005 (D McKay) - Pyrrhotite and pyrite generally constitute 1% of the mafic metavolcanic rocks and occur as fine- to medium-grained, disseminated grains. The iron formation contains up to 10% fine- to coarse-grained, pyrite, pyrrhotite, chalcopyrite and sphalerite as disseminated grains, irregularly shaped patches and narrow (1 to 2 mm wide), foliation-parallel laminae and discontinuous veinlets. Grab samples collected from the occurrence in 1993 by D.B. McKay for the OGS returned assay values which varied from 134 to 2707 ppm Cu and 223 to 11680 ppm Zn.
