Point Location Description: Occurrence
Location Method: Conversion from MDI
Access Description: The occurrence is located 39 km north-northwest of the town of Schreiber. At present (1993) access to the occurrence is difficult (Figure 10) and is best achieved by helicopter. The closest road is approximately 13 km to the northeast and accesses the northern end of Dickison Lake. Another road, approximately 5 km to the northwest provides access to the western (opposite) side of the Gravel River Valley.
PAST: 1954 Large quartz veins were identified by M.W. Bartley as part of a regional reconnaissance survey conducted for the Canadian Pacific Railway Company. CURRENT: 1994 The quartz occurrences are all open.
Province: Superior
Subprovince: Quetico
Geological Age: Archean
Dec 07, 2005 (R Degagne) - The occurrence is located within the Quetico Subprovince and was mapped by Carter (1975). The area is underlain by a mixture of metasedimentary schists, gneisses and migmatitic rocks of Precambrian age. The occurrence located by the author is near a contact between the metasediments and migmatites. To the north is the Gravel River Fault zone. The fault is the major structural feature in the area and is marked by a 61 m (200 feet) cliff on the north side. The Gravel River and valley is within the fault zone.

Geologist: R Degagne
Notes: Visited in September, 1993 by P. Hinz | R. M. Landry (OGS OFR 5889, 1994) . COMMENTS/RECOMMENDATIONS: When the results are compared with specifications for silicon metal it is seen that the primary impurities (Al2O3, Fe2O3, CaO and TiO2) are all above the required tolerance levels. The results are encouraging and the author feels they warrant further investigation.
