Location Method: Data Compilation
Access Description: The International Wildrose Resources property is located in the Prairie Cove-Prince Point-Fitzsimmons Rocks-McKellar Harbour area, approximately 30 km west of Marathon, and along the northern shore of Lake Superior. The occurrence is in Walsh Township. Several base metal and gold showings have been discovered including the Prince Point occurrence. The International Wildrose Occurrence is located 200 m north of Prince Point and a sulphide occurrence is located on the Fitzsimmons Islands. Access is via the Trans Canada Highway approximately 7 km east of the Steel River bridge. A bush road heads south to Prairie Cove, however, the crossing at the railways has been removed. Access to the showing is via boat launched at Prairie Cove or Neys Provincial Park.

Dec 07, 2005 (D McKay) - Patterson et al. (1987) state: The general geology consists of predominantly mafic metavolcanics, mafic intrusive rocks, intercalated felsic fragmental rocks, and iron formation. Late felsic and mafic dikes intrude the metavolcanics. Mafic metavolcanics occur on the Prince Point shore, while metavolcanics of felsic composition with minor intercalated mafic metavolcanic flows occur predominantly on the Fitzsimmons Rocks. Felsic fragmental rocks, several hundreds of metres in width, were observed, possibly suggesting the presence of an ancient volcanic vent in the area. Two volcanic cycles are presumed; however, younging indicators were not readily identifiable. The felsic metavolcanics consist of a monolithic, clast supported, fragmental unit. The matrix varies from felsic to mafic in composition. Felsic fragments displaying porphyritic textures and up to 1 m in length were observed; however, the fragments average 5 to 20 cm in size. Numerous fragments display stretched or tear-shaped terminations, suggesting that these fragments have undergone deformation. A well developed cleavage, oriented subparallel to the long axis of the fragments, strikes 076 degrees. Potassic alteration of the felsic fragments was observed in one location. This alteration is presumed to be related to the intrusion of a felsic dike, likely associated with the Coldwell Alkaline Complex. Sulphide mineralization was observed in the matrix of the felsic fragmental unit, and appears to be oriented along the cleavage. Near massive pyrite and pyrrhotite mineralization was observed in several mineralized pods, the largest being 1 by 0.5 m. A chert-sulphide horizon (iron formation ?) enclosed within the mafic metavolcanic rocks in the area is significantly enriched in zinc (up to 5000 ppm) and Cu (up to 400 ppm) (Cavey, Campbell and Dumochell ,1985).

Dec 07, 2005 (D McKay) - The felsic metavolcanics consist of a monolithic, clast supported, fragmental unit. The matrix varies from felsic to mafic in composition. Felsic fragments displaying porphyritic textures and up to 1 m in length were observed; however, the fragments average 5 to 20 cm in size. Numerous fragments display stretched or tear-shaped terminations, suggesting that these fragments have undergone deformation. A well developed cleavage, oriented subparallel to the long axis of the fragments, strikes 076 degrees. It is possible that several of the felsic pyroclastic units observed represent re-sedimented, felsic pyroclastic units and possibly debris flows. In addition the presence of quartz-porphyritic rocks may represent sub-volcanic feeders to a possible felsic volcanic vent site. The chert-sulphide horizon (iron formation ?) enclosed within the mafic metavolcanic sequence is significantly enriched in zinc and copper.

Dec 07, 2005 (D McKay) - Patterson et al. (1987) state: Sulphide mineralization was observed in the matrix of the felsic fragmental unit, and appears to be oriented along the cleavage. Near massive pyrite and pyrrhotite mineralization was observed in several mineralized pods, the largest being 1 by 0.5 m. A grab sample collected from one of the sulphide-rich pods is reported to have contained anomalous amounts of gold (560 ppb) and silver (9 ppm) (LeBel and Campbell 1986, assessment files). Zinc and copper mineralization are reported to occur within cherty rocks in the area. Cavey et al. (1985, assessment files) state: A chert-sulphide horizon enclosed within the mafic metavolcanic sequence is significantly enriched in zinc (up to 5,000 ppm and copper (up to 400 ppm). Rock samples from the metavolcanic sequence in some cases display weak to moderate hydrothermal alteration in thin section and a ubiquitous strong carbonate component. Soil geochemical sampling has outlined some very strong base metal anomalies ranging in magnitude from 300 to 3,700 ppm zinc and 100 to 400 ppm copper. Grab samples collected from the zinc-mineralized cherty horizon by OGS Resident Geologist staff in 1986 returned assay values which varied from 10 to 270 ppb Au, <2 to 3 ppm Ag, 225 to 815 ppm Cu and 330 ppm to 1.08% Zn. While a syngenetic model has not been ruled out for the base metal mineralization, some of the mineralization may have been remobilized within fault zones. In addition the rocks are highly carbonatized. Numerous sulphide-rich gossans were identified by mapping and prospecting. It is also possible that the International Wildrose and Prince Point occurrences occur along the same iron formation It is possible that several of the felsic pyroclastic units observed represent re-sedimented, felsic pyroclastic units and possibly debris flows. In addition the presence of quartz-porphyritic rocks may represent sub-volcanic feeders to a possible felsic volcanic vent site.
