The Kingsville Salt Deposit is located at
Domtar drilled 10 exploration diamond drillholes (DK3-DK12) at depths of approximately 1200 meters. In 1972, Domtar estimated an historical salt mineral reserve of 31.63 million t of Proven and 1.15 billion t of Probable reserves * in the drilled area of 2400 m by 900 m to a depth of 1200 m. The reserves were later reported by Domtar in 1978 **. Depth to the top of the first salt ranges from 400 to 500 meters. The estimated reserves were defined with 10 drill holes, a Bouguer anomaly and a 60% extraction ration through brining process for the Proven reserves and a 40% extraction ration through brining process for the Probable reserves.
Domtar indicated that blocks of salt appropriate for potential brine production cavities were outlined in 10 of their 11 holes.
The salt analytical database on approximately 10,000 salt samples provided by Domtar is the largest available for any salt deposit in the province (Domtar 1978). The success of the brining test (KBW No. 1) and the deposit description by Domtar, indicates that the salt grades and tonnages would be sufficient for economic extraction.
