Point Location Description: PROPERTY (OCCURRENCE)

Location Method: Conversion from MDI

Access Description: The occurrence is located 60 km northwest of Thunder Bay in Goldie Twp., Concession 16, Lots 5 to 8. From Shabaqua drive west on Highway 17 for 4.8 km. Turn right onto a gravel bush road, at 7.6 km cross the Oskandaga River bridge. At 8.3 km turn left and continue to the Oskandaga River. Cross the river and continue for another 0.8 km. The southern boundary of claim TB 514047 crosses the road at this point.



Exploration History

1939: Staked by L. Blank of Winnipeg, Manitoba. Trenching and sampling conducted. 1965: Staked by F. Minoletti of Thunder Bay, Ontario. 1979: Staked by P. Skalesky, W. Peterson and T. Peterson, all of Thunder Bay. 1982: Claims brought to lease. 1990: Claims adjacent to leased claim staked by J. Williams. 1993: Patented claims held by the Petersons and the estate of P. Skalesky. J. Williams still holds the unleased claims.


Geology

Province: Superior

Geological Age: Archean  



Geology Comments

Dec 07, 2005 (R Degagne) - Carter (1990) described the geology of the area: Precambrian rocks are Archean in age. The supracrustal rocks comprise a Keewatin-type sequence of subaqueous metavolcanic rocks with minor interlayered metasediments, a Quetico-type sequence of metasediments with a minor interlayered, probably subaerialmetavolcanics, which overlie and straddle the other two sequences unconformably. The metamorphosed mafic intrusives comprise gabbroic rocks which are commonly strongly magnetic, and the felsic intrusive rocks range from diorite to muscovite granite-pegmatite.

Mineralization Comments

Dec 07, 2005 (R Degagne) - Carter (1990) described the mineralogy: The dike consists of white muscovite-microcline granite-pegmatite, the microcline forming crystals up to 25 cm long and 5 cm across. The muscovite occurs in books with crystals up to 3 cm across. Accessory minerals observed were black tourmaline (schorl), and pale blue apatite; these minerals comprising about 1% of the rock. Quartz occurs as anhedral grains. In addition spessartine was reported (Scott 1981).

Notes: Visited in September 1993 by P. Hinz | R. M. Landry (OGS, OFR 5889, 1994)Carter (1990) described the dimensions of the occurrence: The central part of the dike strikes N20?E, and is 60 m long. This part of the dike, which forms the largest outcrop, is lens-shaped measuring 10-15 m across at the ends and is 20 m across the central part. A detailed study of other outcrops in the vicinity of the main occurrence by Scott (1981) indicates that the dike has an exposed strike length of greater than 1200 feet and a maximum apparent width of 85 feet and dips from between 45? and 50? east (Scott 1981, p. 36), and indicates that the dike extends southwestwards beyond the boundary of the stock to the Trans Canada Pipeline.In 1992 a number of inquiries were made concerning information available of the Buda Pegmatite occurrence. The main interest was the potential for dental grade feldspar in the southwestern portion of the area. No work was recordedand the interested parties did not visit the property.
