Point Location Description: Quarry
Location Method: Data Compilation
Access Description: GENERAL LOCATION: The quarry is located in MacGregor Township, in the southeastern corner of Mining Location 5B. ACCESS: The quarry can be accessed by road from Highway 11/17 at a point 14 km east of Highway 527. The hamlet of MacKenzie is approximately 2.5 km north on this road. Park at the railroad tracks at MacKenzie and walk west along the tracks for approximately 1.5 km. The quarry face lies within a cliff that is about 60 m south of the tracks.
1880s: There is very little information available on this quarry. It is reported that during the early 1880s, 55 men were employed at the site to extract 800 to 900 cubic yards of material per month. The stone was used primarily by the C.P.R. in bridge construction. No assessment reports found on file.
Province: Superior
Geological Age: Archean
Dec 07, 2005 (W Bellinger) - 6) GENERAL GEOLOGY AND STRUCTURE: The quarry is located within an Early Precambrian felsic intrusive body called the MacKenzie Granite. Scott (1990) described the McKenzie Granite: The Mackenzie Granite is situated in the southern potion of MacGregor Township and occupies an area from Mount Baldy in the west to Birch Beach on Thunder Bay to the east, a distance of about 22 km. The Mackenzie Granite has been faulted and generally attenuated in the area 1.6 km northwest of Mary Harbour, but where not faulted, the granitic body is in the order of 3.2 km wide.
