Point Location Description: Small trench
Location Method: Field Visit
Access Description: The occurrence is located approximately 38 km southeast of Manitouwadge and 2.25 km northeast of the northeastern tip of Etna Lake. The occurrence is situated on the west shore of Spruce Bay opposite the mouth of the channel connecting the bay with the main body of the Lake. The occurrence is accessible via motor vehicle followed by travel in boat. From the junction of Hwys 614 and 17, proceed east along Hwy 17 for approximately 17 km to an unnamed gravel road that leads north to a public boat launch on the west shore of White Lake. Proceed northerly, via boat, along the west side of White Lake for approximately 9 km to the entrance of Spruce Bay. Proceed westerly along the south shore of the channel leading into Spruce Bay for approximately 2.25 km to the west shore of the bay. The occurrence is exposed in a small trench located in the vicinity of what G. Siragusa (Map P.2738) refers to as Gossan 33.

Province: Superior
Subprovince: Wawa
Terrane: Wawa-Abitibi
Belt: Schreiber-Hemlo
Geological Age: Archean
Metamorphism Type: Regional
Metamorphism Grade: Amphibolite
Dec 07, 2005 (D McKay) - The occurrence is underlain primarily by a southeasterly-trending sequence of mafic metavolcanic rocks which comprise a portion of the north limb of the Schreiber-Hemlo greenstone belt. Thin units of felsic metavolcanic (?) and metasedimentary rocks occur locally within the mafic metavolcanic sequence. The supracrustal rocks in this area are locally strongly foliated (105 degrees/65 degrees SW) and mineral assemblages indicate they have experienced lower amphibolite facies-grade regional metamorphism. 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. The metavolcanic and metasedimentary rocks in the vicinity of the occurrence have been intruded locally by narrow felsic dikes. A large (60 m wide), north-northeasterly-trending diabase dike is located approximately 250 m west of the occurrence. An elongate (6.5 km long by 300 m wide) body of amphibolitic metagabbro is located approximately 650 m to the north, and the White Lake Fault, a regional-scale northeast-trending structure, is located approximately 800 m to the southeast. In the vicinity of the occurrence, 4 narrow (up to 30 cm wide) ,sulphide-bearing graphitic shear zones occur within the mafic metavolcanic sequence. These shear zones are subparallel to one another, occur within a 10 m wide area, strike approximately 098 degrees and dip 70 degrees to the south. The widest shear zone has been trenched and can be traced from the shore of Spruce Bay inland for approximately 6 m. The shear zones contain up to 5% sulphides.

Dec 07, 2005 (D McKay) - The mafic metavolcanic rocks are typically dark green, fine- to medium-grained, moderately to locally strongly foliated, q-fel-hb schists and gneisses. The metasedimentary rocks are fine-grained clastic units that occur as thin (up to 1.5 m wide) beds intercalated within the metavolcanic rocks.

Dec 07, 2005 (D McKay) - The shear zones contain up to 5% fine- to medium-grained pyrite, chalcopyrite and sphalerite as disseminated grains, fracture-fillings, and coatings along fracture planes. Sulphides also occur within the mafic metavolcanic rocks proximal to the shear zones. Grab samples collected from the occurrence by D.B. McKay in 1992 returned assay values that varied from nil to trace Au, nil Ag, 411 to 567 ppm Cu, 24 to 111 ppm Pb and 1880 to 4040 ppm Zn.
Mar 13, 2019 (Therese Pettigrew) - The Point Zone, located at NAD83 UTM Zone 16 596462 m E, 5405185 m N, assayed up to 0.368% Zn from mafic to ultramafic flows intruded by mafic-ultramafic dykes. The Post Zone, located at NAD83 UTM Zone 16 596497 m E, 5405010 m N, assayed up to 0.853% Zn from a sulphide-bearing BIF intercalated with ferruginous siltstone (Muir, 2000). Homestake reported that a sample collected from the Post Zone assayed 8560 ppm Zn, 547 ppm Cu, 297 ppm Ni, and 18 ppm Mo from a magnetite ironstone that contains 2-5% disseminated and blebby pyrite, bornite, chalcopyrite, and sphalerite (Assessment file 42C13SE2002).
