Point Location Description: General

Location Method: Conversion from MDI

Access Description: The Oxford Prospect is located at the southeast corner of mining claim K.740289 (former mining location S.V. 129) in the Boyer Lake area, immediately south of Sharp Lake, northwest of the old Goldrock townsite, and approximately 2 km north of Trafalgar Bay on Upper Manitou Lake. The property is accessible by a number of overgrown trails. (OFR 5723, p. 263, 264, 1989)

Exploration History

1899: A 77 ft. shaft with 24 ft. of crosscutting was developed on mining location S.V. 129 which was part of a group of four mining locations (S.V. 128, 129, 131, and 166). 1936: Robin Hood Mining Syndicate acquired the four patented claims, as well as twelve additional claims, and conducted trenching and diamond drilling. 1983: Staked by M. Woitowicz. 1984: Transferred to St. Joe Canada Incorporated who conducted geological mapping and sampling over the shaft area. 1986: Transferred from M. Woitowicz to Falconbridge Limited. 1987: Falconbridge Ltd. dropped the option on the property. (Assessment Files, Resident Geologist's Office, Kenora). (OFR 5723, p. 263, 264, 1989)

Lithology

Lithology Comments

Feb 24, 2010 (C Ravnaas) - The prospect is situated within northeast facing massive and pillowed mafic metavolcanic flows of the Pincher Lake Group, on the northwest limb of the Manitou Anticline. The Oxford Prospect is underlain by strongly sheared, sericitized, chloritic, weakly to moderately carbonatized (calcite and iron carbonate), mafic flows and intermediate tuffs containing variable amounts of fine-grained, disseminated, magnetite and pyrite. The shear zone is 30 m to 46 m wide and strikes northeast for approximately 150 m. The sheared rocks have variable strikes and dips within the main shear zone. The shear zone controls a 2.1 m wide stockwork of white quartz veins containing black tourmaline, chlorite stringers, iron carbonate, pyrite [ -cl-4%], and chalcopyrite. A 2.1 m x 3.6 m x 30 m deep shaft has been sunk on t he quartz veins, as well as four trenches southwest of the shaft. Quartz veins are 2 cm to 10 cm wide in the trenches and 0.9 m to 1.5 m wide in the shaft. Two grab samples, taken by the author, of quartz vein material and altered wall rock assayed 130 ppb gold and 185 ppb gold respectively. Grab samples taken from the dump by St. Joe Canada Incorporated, assayed consistent anomalous gold values ranging between 30 ppb gold and 795 ppb gold. Sampling at the 77 ft. level of the shaft, conducted by the Robin Hood Mining Syndicate, gave assays as high as 0.67 ounce gold per ton, and abundant visible gold was observed and panned from the vein (Assessment Files, Resident Geologist's Office, Kenora).
