Trigg Mining Moves Lake Throssell to Next Stage
THE DRILL SERGEANT: Trigg Mining (ASX: TMG) has wasted little time in moving to the next stage of evaluation and development of the company’s 100 per cent-owned Lake Throssell sulphate of potash (SOP) project in Western Australia.
Trigg Mining released a maiden Inferred Mineral Resource estimate just last week of 14.2 million tonnes of drainable SOP and has now commenced a lake surface trenching and test pumping program.
The program follows on from drilling campaigns that established the presence of a high-grade brine deposit within the lake surface and the entire palaeovalley sequence.
The trenching and test pumping program is designed to enable estimates of drainable porosity and permeability of the surficial aquifer to be calculated.
The program includes seven test pit locations and two 100m long trial trenches, with associated monitoring pits.
Pumping from the trial pits and trial trenches will create draw-down of the water table in the surrounding sediments which can be measured by the monitoring pits, with the rate and magnitude of the draw-down used to estimate drainable porosity and permeability of these sediments.
“We’re excited to be back in the field so quickly with the trenching and pump testing program now well underway,” Trigg Mining managing director Keren Paterson said in the company’s ASX announcement.
“The data which we will gather from these work programs will be a crucial input for calculating an Indicated Mineral Resource for the surficial aquifer and in estimating potential flow rates, which will help to establish the economic parameters that will underpin our Scoping Study.
“Having a higher-confidence Indicated Resource will be an important de-risking step for the project and will also form the basis of our planned Scoping Study commencing in the second half of this year.
“Production flow rate data will help us to establish the potential production profile and, ultimately, economic and financial features of the project.
“Following our recently announced maiden Inferred Mineral Resource, this represents another really important step forward towards creating a major new sulphate of potash production hub at Lake Throssell.”
