Point Location Description: Immediately southeast of 'Au' symbol on map 2053.
Location Method: Conversion from MDI
Access Description: The property can be accessed via highway 41, north of Northbrook, turn east onto the Harlowe road and proceed 3.5 km to a laneway on the south side of the road. Follow the laneway to a newly built house. The shaft is located behind this house and to the west of it on the border of lots 31 and 32.
An exploration shaft was put down in 1914-1915 along with another small shaft and numerous exploration pits. In 1961 the Ore Mountain Mining Charter was cancelled. The property was again staked in 1980 and some geological mapping, minor stripping, trenching and sampling was carried out. Also a magnetometer survey was conducted over this showing at this time.
Province: Grenville
Subprovince: Central Metasedimentary Belt
Geological Age: Mesoproterozoic
Dec 07, 2005 (C Papertzian) - Dillon describes the mineralization near the main shaft as follows: 'The mineralization exposed on the Ore Mountain property consists of pyrite and minor aresenopyrite associated with a narrow zone (0.5 to 1.5m) of quartz stringer veins hosted in a dark grey to black amphibolite-biotite schist. The quartz veins and well developed foliation within the schist host rocks trend parallel to the regional foliation directions which trend (70 to 85 degrees) and 70 to 85 degrees north. At the main shaft site discontinuous quartz stringers, 2-8 cm wide are exposed across approximately 1 m of the shaft. The host rocks appear to become more micaceous in the footwall of the veins whereas the hanging wall consists of an amphibolite showing relict feldspar porphyroblasts. Pyrite, arsenopyrite and minor magnetite are disseminated within the hornblende-biotite schist with lesser amounts of pyrite and traces of magnetite disseminated in the amphibolite hanging wall of the trench. No gold was visible in the trench material. Although pyrite and arsenopyrite are disseminated in host and wall rocks much of it is localized along margins of quart stringers within sheared hornblende-biotite schist.'

Notes: This deposit was visited on October 1st, 2004 in the company of the mine hazards co-ordinator, D. Cranston. Of interest was the exploration shaft that was excavated on lot 31, concession 1. It is approximately 3 m square by 15 m deep and was excavated in 1914-1915 along with another small shaft and numerous exploration pits. It was recommended that this exploration shaft be filled after determining who the mineral rights holder was. The best assay value from this property was 0.38 oz/ton Au obtained from a grab sample north of the shaft in 1983.
