1988 Report on Auger Drilling for Alexandria Station EL 4968

Abstract

This work is part of much larger search by Northern Cement to locate high-grade gypsum in economically viable quantities. The area of the EL attracted attention because of the gypsum crystals exposed during the building of turkey's nest dams in the black soil plains. An earlier ground reconnaissance found gypsum at Six Mile and 18 Mile waterholes and in the soil near Six Mile waterhole. Gridded drilling was conducting using a slewing crane and pendulum borer. This is the results of the second phase of drilling. The limits of the deposit near Six Mile Waterhole are still not defined. Indications are that there may be in the order of 1.2 million tonnes of gypsum in the area.
