Trigg Mining Releases Maiden Indicated Resource for Lake Throssell Sulphate of Potash Project

THE DRILL SERGEANT: Trigg Mining released a maiden Indicated Resource for the company’s Lake Throssell sulphate of potash project in Western Australia.

Trigg Mining has estimated a Drainable Indicated Mineral Resource of 1.9 million tonnes sulphate of potash (SOP) at 4,985mg/L potassium (or 11.1kg/m3 potassium sulphate (K2SO4)).

The Mineral Resource Estimate (MRE) was based on results of recent trench pump trials of the surficial aquifer resource the company announced to the ASX in July 2021.

As a result of this MRE upgrade, 13 per cent of the previously announced total MRE of 14.3 million tonnes of drainable SOP at 4,665mg/L potassium (or 10.4 kg/m3 K2SO4) is now in the higher-confidence Indicated category and available for conversion to Ore Reserves.

“This is another great result by our team, which puts Trigg Mining front and centre of the new-generation SOP industry in Western Australia,” Trigg Mining managing director Keren Paterson said in the company’s ASX announcement.

“Having delivered our maiden Inferred Resources just over two months ago, we have moved rapidly to estimate a high-quality Indicated Resource that will provide the basis for the initial payback period to underpin the Scoping Study that is currently underway and due for completion later this quarter.

“In addition to improving our confidence in the current Mineral Resource, we have also demonstrated continued upside potential with an updated Exploration Target of 2.6 to 9.4 million tonnes of SOP, encompassing tenements to the north and south which are awaiting grant.

“We expect to convert additional tonnes to Indicated status next year as we progress work on the deeper portions of the resource and further expand our overall inventory with further drilling.

“However, having a maiden Indicated Resource allows us to progress our economic evaluation of Lake Throssell to the next stage, and commence initial discussions with potential off-takers and financiers.

“Together with our Lake Rason project, we now have a high degree of confidence that we have a large and potential multi-decade, long life potash project in Western Australia.”
