These positions which will be targeted in an upcoming maiden aircore drilling program as they have strong potential to enhance the high-grade Lake Throssell discovery.
The company believes these targets have strong potential for large-scale SOP mineralisation, particularly given that similar systems in the region are currently subject to mining studies.
“Further evidence of potential”
Trigg Mining’s managing director Keren Paterson said: “The results of the gravity survey provide further evidence of the potential of the Lake Throssell Sulphate of Potash Project to host a high-grade deposit of this essential natural mineral fertiliser for global food security.
“The data clearly indicates the presence of a large palaeovalley system beneath the lake surface, which we believe could host strong SOP mineralisation.
“This potential will be targeted by our upcoming maiden aircore drilling program as soon as the COVID-19 travel restrictions allow.”

Cornerstone of SOP hub plan
The Lake Throssell project forms the cornerstone of Trigg Mining’s plans to establish a significant SOP production hub in the Laverton District.
Results from previous hand-auger sampling indicated a high-grade project with samples across the playa area returning grades of up to 14,800mg/l SOP with an average grade of 11,800mg/l.
An off-lake ground gravity survey undertaken in March 2020 identified several strong indicators of a palaeovalley underneath the lake surface and potentially extending into the new tenement applications to the north and south of the main playa area.
This interpreted aquifer system will be targeted with up to 30 off-lake aircore drill holes.

The maiden aircore drilling is planned to begin across the project as soon as access can be re-established following COVID-19 travel restrictions.
Aircore program approved
POW approval for this aircore program has been received.
This program is designed to establish if the tenor of surface mineralisation can be reproduced in the sub-surface aquifer, as is the case at the company’s Lake Rason SOP Project further to the south.
Trigg Mining is looking to secure Australia’s sustainable agriculture future through the exploration of essential potassium fertiliser, sulphate of potash, necessary for global food production and human nutrition.
SOP provides essential macronutrients for plant growth without any detrimental elements, such as chloride found in muriate of potash (MOP).
In addition, SOP can be produced sustainably through the solar evaporation of potassium-rich hypersaline brine water, without the need for large open pits or waste-rock dumps.
