Point Location Description: General
Location Method: Conversion from MDI
Access Description: The Minnehaha Lake Prospect (on former mining locations S.V. 234 and S.V.235) is located a few hundred metres due north of the large bay at the east end of Minnehaha Lake, between Minnehaha Lake and Whitewater Lake to the north, in the Turtlepond Lake area. The prospect is accessible by boat. (OFR 5723, p.246-247)
1905-1906: A 100 ft. shaft with a 25 ft. crosscut at the bottom was sunk by Minnehaha Gold Mining and Smelting Co. 1908: A 25 ft. test pit was sunk and some trenching was completed. 1910-1911: The property was reactivated in 1910 and a 40 ft. adit was developed by 1911 when operations ceased. 1960: Staked by E.G. Stinson 1982: Staked for J.P. Sherridan 1983: Optioned by Asamera Minerals who added it to a claim group of 97 contiguous claims; conducted ground geophysics humus & rock sampling, and geological mapping. 1987: The claims subsequently lapsed and was then staked by I.J. Riives and A. Glatz (prospectors in Dryden). (OFR 5723, p.246-247 & MP138, p.20)

Mar 05, 2010 (J Bongfelt) - The Minnehaha Lake Prospect is licated within the Lower Wabigoon Volcanics and is in close proximity to the Manitou Straits Fault to the east. (OFR 5723, p.246)

Mar 05, 2010 (J Bongfelt) - The shaft and test pits at the Minnehaha Lake Prospect have been sunk on fracture-controlled quartz veins hosted by massive, brecciated, pillowed, and amygdaloidal mafic metavolcanic flows. It is difficult to observe the strike of the quartz veins due to poor exposure. The veins generally consist of white to gray quartz, calcite, and iron carbonate, narrow bands and fracture-fillings of black tourmaline and chlorite, and disseminated, fine-grained pyrite and chalcopyrite. The sulphides may also occur as large blebs in the quartz. At the main shaft the wall rocks are dark green, weakly carbonatized, chloritic, and contain disseminated pyrite and chalcopyrite at vein/wall rock contacts where there is intense shearing. (OFR 5723, p.246)
| Rank | Mineral Name | Class | Economic Mineral Type | Alteration Mineral Type | Alteration Ranking | Alteration Intensity | Alteration Style |
|---|---|---|---|---|---|---|---|
| 5 | Chalcopyrite | Economic | Ore | ||||
| 10 | Pyrite | Economic | Ore | ||||
| 15 | Tourmaline | Economic | Ore |
Mar 05, 2010 (J Bongfelt) - Three grab samples of the quartz vein material, taken by the author from the dump at the main shaft assayed >2, 60, and 1350 ppb gold, while a sample of pyritic wall rock assayed 14 ppb gold. Grab samples of the pyritic wall rock, taken by the author at the test pit, assayed 5700 ppb gold while a sample of the quartz vein assayed 490 ppb gold. More gold mineralization occurs in the wall rock than in the quartz vein and the alteration and appearance of the wall rocks is very similar to that at the Whitewater Lake Occurrences.
