Mulgundawa Investments Pty Ltd has a range of salt - commercialising interests in South Australia, where it trades as Mulgundawa Salt. The company presently has extractive operations occurring on a number of lakes in the Brinkley area in the vicinity of Mulgundawa, a hamlet close to the northern shore of Lake Alexandrina, where natural and underground brines are used in the production of salt by solar evaporation. The company operates a manufacturing facility at the Mulgundawa site, on PM 38, where the unwashed crude salt (halite, NaCl) that is harvested from various saline lakes on its Mining Leases ML 5975 Nalpa West and ML 5976 Nalpa East, and also on PM 38, is processed into packaged salt products. These products are primarily sold domestically to the hide and skin tanning, swimming pool water fill maintenance and stockfeed industries. Mulgundawa Salt is presently expanding its salt production capacity and is planning to develop a number of regional saline lakes for the supply of salt or the supply of brine. The expansion will provide additional crude salt tonnage as feedstock to the manufacturing operations. The subject EL 4378 of ~52 square km extent was taken up to allow for this expansion. During the first licence year, the company evaluated the potential of a number of sites for solar salt production by performing limited sampling of surface waters and salt deposits to confirm that the chemical composition of groundwater at each location approximates to the composition of sea water. Regionally, the saline groundwater is very close in chemical composition to sea water and contains around 75% NaCl. Mineral Claims (nos 4198-4200, 4275 and 4276) were taken up or progressed towards mining lease status via applications made during September and October 2010, to secure tenure of five new sites deemed suitable for solar salt production. During licence Year 2, evaluation of the salt lakes of interest was continued. Topographic surveying was undertaken to establish what are the lakebed elevations across different sections of the lakes. Australian Groundwater Technologies were engaged to undertake an hydrogeological study, and completed the first phase of this work. During licence Years 3 through 5, no new work was done. The consultants' hydrogeological study was progressed. At the end of the reporting year it was decided to fully surrender exploration tenure.
