Point Location Description: Quarry

Location Method: Field Visit with GPS

Access Description: GENERAL LOCATION: The quarry is located beside the C.P.R. in the southern portion of Lot 20, Conc. XI; approximately 1.2 km north of the town of Marathon. ACCESS: A C.P.R. access road follows the tracks, north out of Marathon. Park at the end of this road and walk north along the tracks for approximately 1 km. The quarry is on the east side of the tracks.



Exploration History

1880: “black granite” was first quarried at marathon by the CPR for construction of the rail bridges over the Pic and Little Pic Rivers. 1929-30: Peninsula Granite Quarries owned the property and quarried 24 carloads of material. 1931: The ground covering the black granite was purchased by the Cold Spring Granite Company from the Peninsula Granite Quarries Ltd. During the year, a new quarry was opened with a new derrick, drilling equipment, and power plant. Twelve men were employed to quarry blocks that weighed up to 35 tons. In 1931, twenty car loads of black granite were sent to Cold Spring, Minnesota for fabrication (Thomson 1932; The Northern Miner 1931). In the late 1930s the quarry operations were abandoned due to the lack of market. 1994: The patented claims are currently held by James River-Marathon Ltd.

Geology Comments

Dec 07, 2005 (W Bellinger) - General Geology: The claims are underlain by Fe-rich augite syenite (Walker et al. 1992) of the Proterozoic Coldwell alkalic complex. Geological mapping over the area was done by Puskas (1967) and recently by Walker et al. (1991, 1992, 1993). Walker et al. (1992) described the iron-rich augite syenite as follows: The iron-rich augite syenite appears to be a low angle sheet-like intrusion, which dips approximately 15 degrees toward the centre of the complex. It intrudes the basaltic xenoliths of the roof pendant and the Eastern and Western Gabbro, and it has inclusions of recrystallized amphibole quartz syenite. A variation in mineralogy from the bottom to the top through the sheet is present and consists of: fayalite-iron-rich, augite-magnetite syenite; iron-rich augite syenite; fayalite-iron-rich augite syenite; and amphibole syenite JOINTING: Two sets occur at the quarry. The most prominent strikes 335 degrees and dips 50 degrees S while the other set strikes 005 degrees and is vertical. The sheeting ranges from 0.45 to 2.4 m and dips 8 to 10 degrees W (Thomson 1932).

Mineralization Comments

Dec 07, 2005 (W Bellinger) - MINERALOGY: Walker et al. (1992) described the mineralogy of the iron-rich augite syenite: Iron-rich augite syenite, which forms the majority of the intrusion, typically contains iridescent tabular to lath-shaped feldspars with cryptoperthitic intergrowths and up to 30% interstitial, iron-rich augite. Variable amounts of fayalite, amphibole, aenigmatite and rare quartz occur in the subunit. The rock is generally black to olive-brown, coarse grained and massive. CHEMICAL ANALYSIS: , Sample No. 56.97 SiO2, 13.40 Al2O3, 17.26 Fe2O3, 0.48 MnO, 0.28 MgO, 3.22 CaO, 4.68 Na2O 4.52 K2O, 0.56 TiO2, 0.00 P2O5. Analyses conducted by Geoscience Laboratories, Ontario Geological Survey, Toronto Although the Cold Spring quarry site itself is not amenable to quarrying due to its small size, there are numerous sites in the immediate vicinity which may have potential. Since the iron-rich augite syenite outcrops over a very large area within the Coldwell Complex, there may be some suitable sites yet to be found.

Production Data
Year Tonnes Commodities Reference Comment
1931 1000 20 carloads of black granite were shipped. Quarry had been opened to a depth of 14 feet.
1930 1200 Thomson, 1931 1929-30: 14 months production, 24 carloads of black granite were shipped. The granite is sold at $2.50 per cubic foot. The black granite was used in the construction of several buildings in Toronto (including the Eaton building on College St.), Chicago, Detroit and other Midwestern cities
