Point Location Description: Trench

Location Method: Data Compilation

Access Description: The Qued QT-1 gold occurrence is located approximately 31.4 km south-southeast of Manitouwadge, 2.6 km west of Theresa Lake and 2.3 km south of the southernmost tip of Dead Otter 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 8.1 km to where a 785 m long, north-trending trench (Qued Resources Limited trench QT-01) crosses the road. Proceed north along this trench for approximately 325 m to the vicinity of the occurrence. A sample of fine-grained mafic-rich clastic metasedimentary rock collected from the trench in this area is reported to have returned assay values of up to 8850 ppb Au (Siragusa 1985).

Geology Comments

Mar 14, 2019 (D McKay) - The Qued QT gold occurrences are 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 1.25 km north of the contact with the Musher Lake Pluton. In the vicinity of the occurrence, 3 parallel, east-southeast trending, interflow metasedimentary units (including iron formation) have been recognized (Cavey and Dumouchel 1985). The Qued QT-1 gold occurrence is located in the central metasedimentary unit.

Lithology

Lithology Comments

Mar 14, 2019 (D McKay) - The sedimentary rocks hosting the occurrence consist of laminated arkose and greywacke containing up to 10% disseminated pyrite and pyrrhotite, minor garnetiferous bands, and chert. The majority of the rock exposed in trench QT-3A is comprised of locally pillowed, mafic metavolcanic flows. These rocks are typically rusty-weathering, dark gray-green, fine- to medium-grained, weakly to moderately foliated (100 /82 SW), locally strongly carbonatized (with calcite) and locally moderately to strongly magnetic. A narrow (50 cm wide), sulphide-bearing, banded iron formation occurs within the volcanic flow sequence approximately 23 m north of the south end of the trench. The mafic metavolcanic rocks are brecciated and carbonatized adjacent to the iron formation. Gold mineralization is reported to occur in this brecciated zone.

Mineralization

Mineralization Comments

Mar 14, 2019 (D McKay) - Grab samples of fine-grained, mafic, clastic, metasedimentary rock collected from the Qued QT-1 showing, in 1985 by G. Siragusa for the OGS returned assay values which varied from 160 to 8850 ppb Au. At the Qued QT-3A showing, pyrrhotite and pyrite generally constitute less than 1% of the mafic metavolcanic rocks, but concentrations of up to 5% occur locally. Samples of brecciated and carbonatized mafic metavolcanic rock collected from the occurrence in 1985 reportedly returned assay values of up to 3125 ppb Au over 1 metre (Cavey and Dumouchel 1985, p.19). Grab samples collected from the occurrence in 1993 by D. McKay for the OGS did not contain appreciable amounts of gold but did contain up to 1239 ppm Zn. At the Qued QT-1A showing, the mafic metavolcanic rocks contain 1 to 2% fine- to medium-grained pyrrhotite and pyrite as disseminated grains, irregularly shaped patches and narrow (1 mm wide), foliation-parallel laminae. The metasedimentary rocks locally contain up to 30% fine- to medium-grained pyrite, pyrrhotite and rare chalcopyrite as disseminated grains and narrow foliation-parallel seams or bands. The iron formation is moderately to locally strongly magnetic. Grab samples of deeply weathered, carbonatized and weakly pyritized, mica schist collected from the metasedimentary unit in 1993 by D. McKay for the OGS returned assay values which vary from <0.01 to 0.17 ounce Au per ton. One of these samples was assayed to determine its Ag, Cu and Zn content and was found to contain <0.1 ounce Ag/ton, 285 ppm Cu and 168 ppm Zn.

Mar 14, 2019 (Therese Pettigrew) - DDH Q97-2 drilled by Battle Mountain in 1997 assayed 0.643 g/t Au over 1.0 m (Assessment file 42C13SW0177).
