Point Location Description: SHAFT in Guibord tp.
Location Method: Conversion from MDI
Access Description: A point 1.57 km east and 0.01 km south of the northwest corner of Guibord Township. Overgrown pits and trenches blasted into quartz veins occur in the north half of patented claim no. 2252 (the northeast quarter of the north half of lot 11, concession VI, Guibord Township). These are most easily reached by following the White-Guyatt/Croesus gold mine access road (as indicated by Prest (1953) and Satterly (1952)) from Highway 101. The pits and trenches are a few tens of metres north of Highway 101, as indicated by Prest (1953).
1909: Claims in the area (including the northeast quarter of the north half of lot 11, concession VI, Guibord Township, which would eventually be staked as claim no. 2252) were staked by J.A. Monahan (Prest 1953). The Gold Pyramid Mining Co. of Larder Lake Ltd. was incorporated and sank a 25 foot deep exploration shaft on what was to become patented claim no. 2252 (Gibson 1910, Corkill 1911). 1911: Gold Pyramid Mining Co. sank two (additional?) prospect shafts to depths of 27 and 32 feet and erected on site a 5 stamp mill. 1916: The surface plant was destroyed by the Great Fire (Knight et al. 1919; The Northern Miner, June 30, 1917), before which time some Croesus Mine ore was milled (The Northern Miner, April 15, 1916). 1929: The north shaft was dewatered, sampled, and both veins were surface sampled (Prest 1953).

Province: Superior
Geological Age: Archean
Metamorphism Grade: Greenschist
Dec 07, 2005 (C Salo) - Geological mapping (Prest 1953; Satterly 1952; Johnstone and Trowell 1985; Jensen and Baker 1986; Johnstone 1987; Johnstone and Steele 1989; Troop 1989; Vagners 1984; McClenaghan et al. 1988, 1987; Steele 1988) indicates that bedrock the occurrence area consists mainly of weakly metamorphosed (greenschist or lower metamorphic facies) turbiditic sediments of the (Archean) Porcupine Group and subaqueously deposited felsic to ultramafic volcanic rocks of the (Archean) Stoughton-Roquemaure Group. Bedrock strikes southeast, dips steeply, faces north, and occupies part of the south limb of the southeast striking and northwest plunging McCool Hill Syncline. Intrusive rocks in the area include felsic dikes, lamprophyre dikes, and narrow (tens of metres in width) north striking diabase dikes of the (Proterozoic) Matachewan swarm (Heaman 1989). A recent geophysical survey of Guibord Township (OGS 1984) failed to detect any significant bedrock conductors to be associated with the auriferous quartz veins.

Dec 07, 2005 (C Salo) - Two narrow (no wider than about 1 foot) but persistent (traceable for hundreds of feet) 065 striking and vertically to steeply south dipping quartz-Fe-dolomite veins were the focus of surface and underground exploration and mining operations by Gold Pyramid Mining Co. of Larder Lake prior to 1916. The veins are hosted by (metamorphosed) turbiditic wacke and siltstone immediately southwest of the Contact Fault, a ...bedding parallel strike fault... which dies out eastward at the southern edge of Munro Township and cuts up-section in south-central Beatty Township... (Johnstone 1987, p.262). Near the occurrence, the steeply north dipping Contact Fault is localized along the contact between underlying Porcupine Group sediments and overlying Stoughton-Roquemaure Group volcanic rocks, and is locally characterized by lenses of carbonatization, quartz-carbonate veining, and sericitization (Johnstone and Trowell 1984, Johnstone 1987). Near the now flooded and detritus filled Gold Pyramid Mining Co. workings, intercalated wackes and argillites strike 152 and dip steeply south. Numerous fracture sets are developed in the sediments near the Contact Fault; mutually offsetting relationships suggest that these were formed approximately contemporaneously. A single well developed foliation striking 060-065 and dipping south 64 degrees occurs as a sericitic foliation in argillaceous interbeds and as a narrow, often quartz filled fracture cleavage in coarser grained wacke interbeds. The Gold Pyramid Mining Co. veins or vein systems appear to be oriented subparallel to this foliation.
