Primary Commodities: Wollastonite
Township or Area: Leeds
Latitude: 44° 19' 42.23" Longitude: -76° 13' 3.13"
UTM Zone: 18 Easting: 402925 Northing: 4909069 UTM Datum: NAD83
Resident Geologist District: Southern Ontario
NTS Grid: 31C08SW
Point Location Description: From OGSEarth and property visit information
Location Method: Other
Access Description: Access is via Highway 2 approximately 3 km west of Gananoque; turn north on a lane leading to 4732 Highway 2, follow lane to an active sand pit 500m N of the highway.
1986: wollastonite was discovered by M. Badham in a rock pile from a building site approximately 1.4km west of the property; 1988: Cominco and Platinova Resources optioned several lots over the occurrence and conducted 12 diamond drill holes totalling 508m on the property; 1990: 22 diamond drill holes were completed totalling 766m. Drilling indicated that the wollastonite-bearing zone is up to 10 m thick on the south limb and 14 m thick on the north limb of an anticline. Flotation tests were conducted on drill core materials that indicated that while the material ranged up to 82.5% wollastonite mineral separation was challenging and the flotation yielded only 47%.

Aug 11, 2016 (L Hall) - High concentrations of wollastonite occur in gneissic metasedimentary rocks that are exposed in a domal, doubly-plunging antiform cored by “white pegmatite” (Wynne-Edwards 1962). The “white pegmatite” has been described by other workers as 3 distinct lithologies: quartzite; massive, coarse grained quartz and feldspar rock; and a calcsilicate composed primarily of quartz, diopside and wollastonite (Cominco 1990). This assemblage has been metamorphosed to upper amphibolite to granulite facies. The wollastonite is the result of high-grade metamorphism of quartz sanstone interlayer with or cemented by carbonate.

Notes: District and Regional Land Use geologists accompanied J. Maskel to the sand pit operated by the patent owner G. Best to examine outcrops exposed at the north end of the sand pit. Expansion into bedrock aggregate by property owner under consideration.
