Trigg Mining Confirms Extensive High-Grade Brine System at Lake Throssell

THE DRILL SERGEANT: Trigg Mining (ASX: TMG) reported assay results from a recently completed air-core drilling program at the company’s 100 per cent-owned Lake Throssell sulphate of potash (SOP) project, located east of Laverton in Western Australia.

Trigg Mining described the results from the expanded 54-hole program as being, “highly encouraging” with 253 brine samples submitted for assay, returning high-grade results of up to 5,800mg/L potassium (12.93kg/m3 SOP), with an average grade of 4,488mg/L potassium (10.01kg/m3 SOP).

Of note, 98 per cent of assays exceeded 4,000mg/L potassium (8.92kg/m3 SOP) and 50 per cent exceeded 4,500mg/L potassium (10.04kg/m3 SOP), confirming the extensive high-grade, low variability tenor of the brine within Lake Throssell palaeovalley system.

The drilling also confirmed the presence of a broad palaeovalley of up to 5km wide and about 100m deep over a strike of 36km.

Trigg Mining has now commenced work on a maiden Mineral Resource Estimate, which is on track to be completed in Q2 2021.

“These are hugely encouraging results that confirm that Lake Throssell is a large-scale and remarkably consistent high-grade SOP project,” Trigg Mining managing director Keren Paterson said in the company’s ASX announcement.

“It is particularly pleasing that the average grade of our assays has come in at the very upper-end of our Exploration Target, which provides a strong foundation for the completion of a maiden Mineral Resource estimate early next quarter.

“We are also looking forward to getting test trenches in place to commence the work to better understand Lake Throssell’s hydrogeological characteristics, which will be an essential input for feasibility studies.”
