Point Location Description: A point 2.40 km north and 3.48 km east of the southwest corner of Munro Township.
Location Method: Conversion from MDI
1916: A shaft is reported (The Northern Miner, April 22, 1916) to have been sunk on the Falkenham property, which may have been, in part, the northeast quarter of the south half of lot 10, concession III, Munro Township. 1947: Big Game Mines Ltd. diamond drilled 1 hole totalling 1,051 feet near the southwest corner of the northwest quarter of the north half of lot 9, concession III, Munro Township. 1952: Satterly reported that a 6x8x20 foot deep shaft (likely the Falkenham shaft) is sunk on a quartz-carbonate vein breccia within a Matachewan diabase dike. Satterly reported that a weakly mineralized (chalcopyrite bearing) vein sample from the shaft area averaged 0.01 ounce of gold per ton. 1984: Manville Canada Inc. completed geological, magnetic, HL electromagnetic, and radiometric surveys of claims formerly held by Big Game Mines. 1987: D. Lalonde (of Timmins) completed magnetic and VLF electromagnetic surveys and mechanical overburden stripping within and near the northeast quarter of the south half of lot 10, concession III, Munro Township (near what is believed to be the Falkenham shaft). Grab samples from the stripped areas are reported to average 0.016-0.091 ounce of gold per ton. Bruneau Mining Corp. optioned several of the Lalonde claims (including most ground formerly held by Big Game Mines) and diamond drilled 3 holes totalling 812.0 m to test at depth anomalous gold mineralization exposed by D. Lalonde. 1988: Manville Canada Inc. diamond drilled 1 hole totalling 410 feet in the southwest quarter of the north half of lot 8, concession II, Munro Township. This hole yielded a 4 foot core length which averaged 0.022 ounce of gold per ton. Bruneau Mining Corp. diamond drilled 13 additional holes totalling 2,021 m to test at depth the Lalondeauriferous zone.

Dec 07, 2005 (R Degagne) - Satterly (1952) reported that: ...in the southern part of ... the southwest quarter of the north half of lot 8, concession II, the lavas have been sheared and replaced by carbonate, and some exposures are green mica-carbonatized schists. Assumed strike faults, trending N. 70 W., are shown on the map. Quartz veins cut carbonatized lava or green mica- carbonate schist and have been explored by six pits and trenches. The vein material is mainly a barren blue-grey quartz, but in one pit quartz, grey carbonate, and grey lava are mineralized with stringers and splashes of pyrite, chalcopyrite, and sphalerite. A grab sample of well-mineralized material taken by the writer assayed 0.03 ounces of gold per ton. (p. 45-46). Intrusive rocks in the area include narrow (tens of metres in width) diabase dikes of the (Proterozoic) Matachewan swarm (Heaman 1989), narrow (metre scale) lamprophyre dikes, and felsic dikes. A recent geophysical survey of Munro Township (OGS 1984) failed to detect any significantly anomalous bedrock conductors to be associated with areas of known gold mineralization in the area.
