Salt Lake Potash Limited announced that initial pump testing of trial trenches at the Lake Wells Project has returned excellent results, substantially increasing the company's confidence in the hydrogeological model for extraction of brine from trenches for production of Sulphate of Potash by solar evaporation. surface aquifer exploration program highlights: an 8.5 tonne amphibious excavator has completed 207 shallow test pits and 8 trial trenches at the lake wells project. Sustained pump tests have been completed on two trenches in the southern part of the Lake. Highlights include flow rates above 1 litre per second (L/s) from a 50m long trial trench recorded during the duration of the test. Modelled annual flow rates of 1.1 - 1.3L/s based on a 1 year simulated model of the results recorded during the 50m trial trench pump test. The results from these initial trench pump tests have confirmed the potential of trenching to produce sufficiently large volumes of brine and will provide valuable data for the pre-feasibility study. The company gained valuable geotechnical information about the material stability and the competency of the open trenches while brine flowed into them from the surrounding aquifer. The trench excavating process also yielded valuable geological, hydrogeological and geotechnical results for siting and designing on-lake evaporation ponds. Work is ongoing on both the surface aquifer, and drilling and test pumping of the deeper paleochannel aquifer, to refine the brine production model for the Project.
