Point Location Description: General location of site with abandoned equipment alongside railway tracks.
Location Method: Field Visit with GPS
Access Description: GENERAL LOCATION: The quarry is located approximately 7.5 km northwest of the town of Marathon on the C.P.R. mainline railway (Figure 19). ACCESS: An access road for the C.P.R. line branches west off Hwy. 17 approximately 7 km northwest of the Marathon airport. The railroad tracks are approximately 2 km southwest along this access road. Upon reaching the tracks, walk north along the tracks for 1.25 km. The quarry is on the east side of the tracks under a powerline.
1929: H. England staked 11 claims covering red and black granite deposits (Daily Times-Journal, Nov. 27, 1930). 1931: Test blocks were removed from the black granite site by Angler Granites Ltd. 1961: Claims staked by James Aldridge, transferred to Angler Mining Company Ltd. 1963 to 1965: Eight diamond drill cores were completed by the Angler Mining Company Ltd. 1985: Staked by D. Petrunka. 1988: Optioned to Cold Spring Granite Canada Ltd. 1990: Property returned to D. Petrunka.

Dec 07, 2005 (W Bellinger) - 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 syenites 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.

Dec 07, 2005 (W Bellinger) - Walker et al. (1992) described the mineralogy of the iron-rich augite syenite: Iron-rich augite syenite, which forms most 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. The jointing has two orientations, 000 to 010 degrees and 160 to 180 degrees, with a separation of 1 to 2 m. Some of these may be surface features as some curve and are discontinuous. Surface spalling is common and sheeting appears thin, reaching a thickness up to 1 m. This may only be a surface feature. It is hard to see the nature of the rock with depth due to the outcrop and overburden. The stone is medium to coarse grained and dark green-black in fresh cut surfaces.

Dec 07, 2005 (W Bellinger) - Walker et al. (1992) described the mineralogy of the iron-rich augite syenite in thin section: the stone is composed primarily of subhedral, <1 to 5 mm crystals of perthitic, turbid, feldspar crystals (50%). The turbid texture is due to the presence of vacuoles and in some crystals the turbidity is zoned. Anhedral to subhedral biotite (10%) and pyroxene (25%) crystals are also present. For the pyroxene crystals it is common to see aegerine-augite crystals with aegerine rims. Opaque minerals and iron staining make up approximately 10% of the rock. The opaque minerals are anhedral and are rimmed by biotite. Although they occur as inclusions in both the feldspar and pyroxene crystal, they are found more commonly in the latter. The iron-staining is very uncommon, but it does occur as spots and along fractures. Physical properties were tested by Geoscience Laboratories at the Ontario Geological Survey in Toronto and the results are as follows: Bulk Specific Gravity: 2.79 %, Absorption 2 hrs.: 0.11, 48 hrs.: 0.19, Compressive Strength: 26,477 (psi), Modulus of Rupture: 1,709 (psi). Geochemical analyses were conducted by Geoscience Laboratories at the Ontario Geological Survey in Toronto and the results are as follows: 57.74 % SiO2, 13.43 % Al2O3, 14.03 % Fe2O3, 0.32 % MnO, 0.34 % MgO, 4.24 % CaO, 4.89 % Na2O, 4.61 % K2O, 1.30 % TiO2, 0.13 % P2O5.
Dec 07, 2005 (W Bellinger) - There are three small areas that have had blocks removed. Just west of the rail line on the on the south side of Redsucker Creek lies one small quarried area with a rubble pile. Under the powerline is a second quarry. Between this site and the railroad lies a third small opening, with a rubble pile and remnants of a derrick. The iron-rich augite syenite outcrops over a very large area in the vicinity of Marathon. Variations include a lighter green stone which contains the schillerescent mineral, spectrolite (e.g. at Shack Lake, MDI42D09NW00018). Although the Angler 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.

Notes: Site was visited in 2024 by S.Hinz, J.Jonsson, and P.Hinz as part of a historic building stone quarry tour to evaluate future potential for building stone in northwestern Ontario.
