Point Location Description: Mineral occurrence at surface symbol (Map, GDIF068)
Location Method: Conversion from MDI
Access Description: A pair of open pits are located on the southern boundary of Lot 2; Concession IV, Dill Township. The property is accessible by travelling 1.6 kilometres southwest of the official Wanup Township intersection on Highway 537 to a northeasterly bearing arterial dirt road just east-of the Wanup General Store. This well maintained road is followed for an additional 1.2 kilometres until a gravel pit access road bearing due north is intersected. Road facilities through the extensive aggregate works are passable by truck for 0.8 kilometre and the last 0.8 kilometre of abandoned dirt trail must be traversed by foot until the mine workings are reached. (OFR5329, p. 81)
1925-1926: The property was operated by Elizabeth Feldspar Mines of Toronto who shipped an estimated 6,096 tonnes of ore in 1925 and 1926. Some spar was used for display purposes at Expo '67, the World's Fair held in Montreal. (OFR5329, p. 81) 1952: Cubar Uranium Mines Limited purchased mining rights to the property and conducted an exploration program for columbium, tantalum and uranium. This program produced unimportant results. (GDIF068)

Jun 05, 2009 (D Scholtz) - Late Precambrian granite pegmatite dikes of the Sudbury area intrude clastic metasedimentary biotite gneiss of the Grenville Province. These intrusions are of undetermined origin but uniformly display white albite feldspar towards the peripheral (contact) zone and pink microcline towards the interior. This suggests a possible albitization of the original microcline pegmatite. As accessory mineralization is varied and dependant on the host rock, the most functional economic classification is based on the nature of quartz-feldspar intergrowth, e.g. massive spar and quartz segregation, graphic intergrowth of spar and quartz and fluctuation of massive segregation and graphic intergrowth. Massive segregation of feldspar and quartz was noted in dikes located in Dill Township (Weisman Hill feldspar mine, Wanup Feldspar Mine Limited and Elizabeth feldspar mine. The developed properties were thoroughly mined in the 1920's and 1930's but rejuvenated interest has been expressed for this ore to be used as raw material for ceramics in electrical insulation.

Jun 05, 2009 (D Scholtz) - A granitic pegmatite lensoid dike intrudes a quartzose metasandstone along a prominent .jointing system. Due to the intrusion and possible movement along the joints a schistose foliation has developed along the contact zone. (OFR5329, p.81) The intrusion into quartzose meta-sandstone is consistent with a vertical joint pattern striking 90°. Accessory jointing in the host rock strikes 20° and 52° with vertical dip. Although the pegmatite is not an obviously zoned deposit, stringers of clean medium to coarse-grained quartz constitute 10% of the deposit. Similarly biotite in stringers up to 1.2 metres long appear parallel with the cleavage of the feldspar. The feldspar is commonly intergrown with quartz, but cleavage of the alkali spar is good. Two trenches have been excavated for production of feldspar. The first trench is described as work was confined to a single opening consisting of a 4.5 meter inclined cut carried 45.7 metres into the face of a low knoll and terminating in a large chamber 20 metres by 10 metres high. The mine has been idle since 1926, while the second trench was a small open-cut is present in the low knoll about 6 meters south of the main workings, and some material was removed from the deposit in 1966 for display purposes at Expo, the 1967 World's Fair held in Montreal. (OFR5329, p. 81) This deposit consists of a 15 metre dyke of medium-grained pegmatite containing a large amount of disseminated quartz and black and white mica in large, thin plates. A small amount of garnet is also present. (GDIF068)

Jun 05, 2009 (D Scholtz) - The rock contains a large amount of disseminated quartz, and black and white mica, in large thin plates. There is also a little garnet present. The mixed character of the rock necessitated careful cobbing and a gasoline driven crushing and picking plant was installed in 1926 in a building erected at the pit entry. Muscovite and biotite crystals up to 1 metre across occur in the dike and coarse graphic intergrowth of quartz and alkalic feldspar are common, but the dike is not obviously zoned. (OFR5329, p. 81) Feldspar occurs in pegmatite cutting metasediments associated with gabbro. Pegmatite body is about 90 metres long and up 34 metre wide. (GDIF068)
