Primary Commodities: Magnetite
Township or Area: Tudor
Latitude: 44° 45' 28.29" Longitude: -77° 37' 22.94"

Resident Geologist District: Southern Ontario
NTS Grid: 31C13SE
Point Location Description: General Property symbol 21 E of SE-end of Glanmire Lake.
Location Method: Conversion from MDI
Access Description: Drive 14.3km north of Cooper Road in Bannockburn. Turn west onto old laneway and travel 400m. Follow small trail south 24m (80ft) to first large pit.
1901: Mining from 4 small open pits by the Anglo-American Iron Company. Shipments recorded include 3000 tons in 1900, and 2,186 tons in 1901 and 1902 (MRC 11, p176). Operations ceased in 1902. In 1969, the property was owned by Inco (Res. Geol. 1986 Field Report). Observations in the Resident Geologist 1986 Field Report state that the workings are more extensive then early reports state, suggesting that more work was done at this site between 1902 and 1986 (perhaps by INCO), even though it does not appear in the references.

Dec 07, 2005 (D Laidlaw) - The magnetite mineralization is of the contact metasomatic variety. Fine to medium-coarse grained magnetite occurs erratically as fine impregnations in a skarn zone 60ft wide and is made up of garnet, hornblende, pyroxene and calcite at the northern contact of the easterly-trending sill-like Tudor gabbro, where it intrudes a narrow band of marble and fine-grained contact metamorphosed amphibolite. The contact zone is cut by calcite veinlets, diorite and trondhjemite dikes and some sulphides, mainly pyrite and pyrrhotite. Much of this area contains ore which is too low in Fe and too high in S to be shipped without previous concentration (Res. Geol. 1986 Field Report).
