48 3E, 30 48 36 30 MARGINAL NOTES Ministry of Ren6 Fontaine Northern Development Minister Flett George Tough Location and Access and Mines Deputy Minister The map area, about 252 km2in extent, comprises the southern Ontario part of the Township of Forbes, all of Conmee Township, and the portion of the Dawson Road Lots that lies between them. It is bounded by Latitudes 48024©45"N and 48036©N, and Longitude 89046©W and the western bank of , and is centred about 38 km northwest of Thunder Bay. Highway 11-17 crosses the eastern part of the map area in a Ontario Geological Survey northerly direction and swings tp a northwesterly direction in the northern part of the map area. Highway 102, which connects with MAP P.2990 Highway 11-17, crosses the eastern part of the region in an Geological Series-Preliminary Map easterly direction. The Canadian National and Canadian Pacific Railways cross the eastern and northern parts of the map area. These highways and railways, together with township concession and side roads, the natural gas pipeline, and hydro-electric power line rights of way provide access to most of the area. The extreme PRECAMBRIAN GEOLOGY west and central part of the region is most easily accessible by helicopter.

Electromagnetic anomalies were detected, but no further exploration work was on record.

Copper In the early 1920s, two pits were put down in a shear zone about 30 to 60 feet (9-18 m) wide, in mafic metavolcanics, for gold mineralization, on a property located in the Dawson Road Lots in the northwestern corner of the map area. The shear zone was subsequently explored for copper when a magnetometer survey, carried out by T.W. Page, located an anomaly about 300 feet (91 m) wide by 6600 feet (2012 m) long, to the south of the shear Fi nmo rk zone. Then in 1955 Kinasco Explorations Limited drilled a short X-ray hole for an unstated length on the zone. In 1956, Lun-Echo Gold Mines Limited drilled 17 diamond-drill holes for 2689.4 feet (820 m) along a strike length of 1100 feel (335 m) on the zone.

Ooid and Silver Exploration for gold was carried out initially on the Lun-Echo occurrence in the Dawson Road Lots in the northwestern corner of the map area. Two pits were put down in a shear zone, as described under "Copper", above. During the summer of 1985, Noranda Exploration Company Limited had a grid cut and were carrying out geological surveys on their property In an area about 3.5 km southwest of Sunshine in LOCATION MAP Scale : 1 548 000 or 1 inch to 25 miles Conmee Township. ws Throughout the current survey, mineralized shear zones and quartz veins were grab-sampled and assayed for gold and silver. The results are reported in the Economic Geology Seclion.

Iron Most of the exploration in the map area was for iron deposits, the region forming the eastern end of the Matawin Iron Range. In 1901, a test pit was sunk on pyritized magnetite-jasper LEGEND* ironstone on the property in the bed of Brule Creek, by the Davis Sulphur Company, to a depth of 5 feet (2 m). PHANEROZOIC In 1909, B.L. Morrison carried out dip-needle surveys near the middle part of the eastern boundary of Conmee Township, over a CENOZOIC sulphide facies ironstone unit consisting of massive pyrite and QUATERNARY pyrrhotite.
