Trigg Mining debuts ‘outstanding’ maiden inferred resource for Lake Throssell SOP project
Limited rig availability delayed the start of drilling, pushing Trigg’s mineral resource estimate to the 2021 first quarter.
Trigg Mining (ASX: TMG) has debuted an “outstanding” maiden inferred resource for its Lake Throssell sulphate of potash project in Western Australia, which the company says highlights the possibility of a multi-decade operation.
The maiden resource for the project totals 14.2 million tonnes of drainable SOP at 4,638 milligrams per litre of potassium (or 10.34 kilograms per cubic metre of SOP).
Underpinning this resource was 5,720m of drilling, with the only required additional information to bump it into the indicated category is test pumping and additional aquifer property data.
Trigg managing director Keren Paterson said it was a “fantastic result” for the company’s shareholders and the new resource places Trigg “front and centre” of WA’s new generation SOP industry.
“The maiden mineral resource clearly shows that Lake Throssell has the scale and grade to underpin a sustainable long-term SOP production hub, particularly when considering its tier one location and proximity to high-quality to energy and transport infrastructure.”
Exploration target represents upside
Trigg also revealed an updated exploration target range of 2.6-9.4Mt at 9.5-10.3kg/m3 potassium sulphate.
The exploration target is based on exploration results to-date on granted tenement E38/3065 and has been applied to four tenements under application that are believed to host similar geology and brine characteristics.
Drilling to-date at the project has confirmed the presence of an extensive palaeovalley system up to 36km long, 5km wide and 100m deep.
An additional 34km of strike has been interpreted to cover the tenements awaiting grant.
Ms Peterson said the company would “immediately” start the next phase of work at Lake Throssell which will comprise trenching and pump testing to convert a portion of the maiden resource to indicated.
“This will, in turn, provide the foundation for a scoping study, which we are aiming to complete by the end of this year,” she added.
