DESCRIPTION OF DEPOSIT
Gypsum of the Jurassic Amaranth Formation was quarried at Elephant Hill for the use in making cement, wallboard, and plaster of paris. The surface of this deposit is covered with boulder clay which, in the vicinity of the quarry, averages 0.6 m to 0.9 m. The gypsum as exposed shows stratification in some places, while in others it is indistinct or absent. A small percentage of reddish clay can be seen between some of the layers, but on the whole the rock is very pure.
At random places the gypsum encloses round boulder-like masses of blue anhydrite and these "boulders" vary in size all the way up to 6 m in diameter. Some of the bands of gypsum carry anhydrite in the middle. Folding the gypsum beds is obvious. An interesting feature of this deposit is the occurrence of selenite in pockets, veins, and sheets through the gypsum as well as in the anhydrite. The continuous masses of transparent selenite are up to 1.5 m long and single cleavage plates more than 0.3 m square can occur. The selenite occurs as thick platy masses that have grown together at various angles.
Chemical Properties: analysis from "old quarry" in Brownell (1931).
Physical Properties: see Bannatyne (1959) and Hoque (1967).
Use: Plaster of Paris, cement, plasterboard.

HISTORY OF EXPLORATION AND DEVELOPMENT
The quarry is located approximately 257 km northwest of Winnipeg and about 6 km northeast of the old Gypsumville quarry.
Elephant Hill is on Crown Land.
1910 - Quarry Lease M-75 was issued to D.G. McArthur for a period of 21 years. It covers parts of l.s. 4 and 5, Sec. 4.
1911 - Assignment of lease to Dominion Gyspum Company Limited.
1915 - Dominion Gypsum Company Limited amalgamated with the Manitoba Gypsum Company and carried on under the name of Manitoba Gypsum Company.
1918 - The rock was quarried only in the winter, and was transported by horse drawn sleds to the Gypsumville quarry. Here is was stored in a stock pile beside the railway track from which it was drawn throughout the year as needed. An annual production of 1360 to 1814 tonnes was quarried from 1918 to 1931 with the exception of 2 years.
1922 - Renewal of Quarry Lease M-75.
1930 - Assignment of lease to Canada Gypsum and Alabastine Limited in April. The Company name changed to Gypsum, Lime and Alabastine Canada Limited.
1933 - Renewal of Quarry Lease M-75.
1952 - Renewal of lease M-75. The lease was assigned to Montreal Trust Company in December.
1959 - Assignment of Lease to Dominion Tar and Chemical Company Limited.
1962 - Rental renewed for 10 years.
1965 - The company name changed to Domtar Industries Limited.
1972 - The leases were renewed. Production has been on an intermittent basis in recent years.
HISTORY OF PRODUCTION
1918 - The rock was quarried only in the winter. It was stockpiled near Gypsumville and used as needed. Annual production of 1360 - 1814 tonnes occurred till 1931 with the exception of 2 years.
1932-1978 - Production continued on an intermittent basis.
