Dec 07, 2005 (P Hinz) - The area is underlain by the High Lake porphyritic granodiorite stock, which intrudes Archean mafic metavolcanic rocks. The stock has been interpreted to be two intrusive phases (Davies 1965, Colvine 1979). Volcanics are represented by basalts and andesites, while the sediments are mostly greywacke, tuffs and arkoses. An east trending band of conglomerate averaging 16m (50 ft.) represents a western extension of the main body of conglomerate present in the vicinity of the Shoal Lake Road. The conglomerate is younger than the porphyry and the surrounding volcanic rocks. It consists of quartz porphyry clasts in a dark matrix of chlorite, epidote, quartz and carbonate. (Davies and Smith, 1988).

Dec 07, 2005 (P Hinz) - The westernmost east-trending embayment of the conglomerate is enclosed by basalt on 3 sides and has an average width of 15m over an exposed length of 95m. Both the basalt and conglomerate are foliated. Clasts are rounded to sub-rounded and consist mainly of quartz porphyry and granodiorite, with lesser amounts of feldspar porphyry and basalt. There is no distinct bedding, but clast size decreases from west to east. Clast elongation, which is slightly greater near the contacts with basalt, is parallel to east-striking foliation and plunges 65E. Spatial relationships between the basalt and conglomerate suggest that the conglomerate is tightly folded synclinally, but clast size distribution does not provide confirmation and the conglomerate may represent a down-faulted block within a fault zone. Quartz is present as lenses, thin veins and irregular masses which cut across foliation, especially in the vicinity of a large pit. Quartz also occurs in tension fractures in basalt at the northern edge of the outcrop. (Davies and Smith, 1988).

Dec 07, 2005 (P Hinz) - Pyrite is present in pockets in the irregular masses of quartz and as disseminations in quartz veins and along slip and foliation planes, especially in the conglomeratic matrix. Minor tourmaline is associated with some of the quartz. (Davies and Smith, 1988).
