PERTH (miningweekly.com) – Junior miner Reward Minerals has reported an increase in the mineral resource of its Lake Disappointment project, following recent testing of core samples from the 2015/16 drilling programme.
The company has increased the project’s mineral resource from 564-million tonnes to 596-million tonnes sulphate of potash (SOP), with the project’s drainable resource estimated at 153-million tonnes SOP in brine with an average grade of 11.35 kg SOP/m3 of brine.
“We are extremely pleased with the results of the independent mineral resource update,” said MD Michael Ruane.
“The numbers speak for themselves. Lake Disappointment stands out as a tier-one SOP deposit and the leading project of its kind in Australia.”
Ruane said the company would now undertake further detailed interpretation of the regional structural data and 2015 core to identify a number of targets for future test production bores to improve the deep resource delineation.
Work is also under way to integrate the shallow push-tube analysis results from 2007 with the 2016 trench testing data, to develop a better understanding of where the high- and low-flow areas of the lake are.
