Location

Township or Area: Fraser

Latitude: 45° 46' 23.91"    Longitude: -77° 27' 33.72"

UTM Zone: 18    Easting: 308790.9   Northing: 5071802.44    UTM Datum: NAD83

Resident Geologist District: Southern Ontario

NTS Grid: 31F14SW

Point Location Description: Diamond symbol ' P48B ', N of CNR, lot 24, con 16.

Location Method: Conversion from MDI

Access Description: A road extends W from Hwy 62 at the Fraser-Alice township boundary. This road ends 7.7 km W of Hwy 62, but a trail leads SW to the Indian River and the CNR track. 3.2 km W on the track a trail from the old station at Indian Siding leads N to the mines. This trail has been flooded in 2 places by beaver ponds, but a new trail has been cut by hunters to bypass the flooded parts. The workings (to the W of the road) are water-filled to the level of the road, though the back wall of the pit was still visible in 1983.

Exploration History

Circa 1936: Jack Collins owned the deposits on the S half of lots 23 and 24. Several openings were made: 50 x 20 ft and 20 ft deep to water level (water 10-20 ft deep) with a bench extending SW from the open cut, which is 40 x 15 ft and 4-8 ft deep. 1944: Another pit, 300 ft N of the open cut is 30 x 20 x 5 ft deep.

Lithology

Lithology Comments

Nov 30, 2020 (Sheree Hinz) - Biotite-pegmatite granite is exposed (though not beyond the workings), hosted by biotite- quartz-feldspar gneiss. Most of the pink feldspar is graphic (very little pure). Biotite occurs in crushed books up to 1 x 2 ft (in the N pit). Grain size in the N pit here is finer than that in the main S pit but related to the same pegmatite. It is doubtful that shipments of # 1 feldspar could have been made from this property. Traces of REE and uranium-bearing minerals are reported.

Mineralization

Mineralization Comments

Nov 30, 2020 (Sheree Hinz) - The pegmatite consists predominantly of quartz, plagioclase feldspar and a graphic quartz and K-feldspar intergrowth. Accessory to trace mineralization includes biotite, sphene, pyrite and metamict U/Th-bearing, and REE-bearing minerals (pyroclore).
