Lake Throssell SOP project receives infrastructure boost

Trigg Mining has welcomed the recent announcement by Australia's federal and state governments of an AUS$20 million contract to seal a 41 km section of the Great Central Road towards the company’s Lake Throssell sulfate of potash (SOP) project in Western Australia.

The road project is designed to provide interstate connectivity for the freight industry, tourists, and communities and also represents a significant access benefit to the Lake Throssell project.

The Great Central Road passes through the Lake Throssell tenements, and the road project will significantly enhance project access, future logistics and transport of people, equipment, materials and product to the regional centre of Laverton.

The imminent lifting of further Covid-19 travel restrictions within Western Australia is also a positive for the project and clears the way for the company’s maiden air-core drilling programme to commence next quarter.

A recent gravity survey at Lake Throssell has defined several targets which are highly prospective for high-grade SOP endowment within the palaeochannel. Trigg believes that these targets have strong potential for large-scale SOP mineralisation, particularly given that similar systems in the region are currently subject to mining studies.

The upcoming drilling programme at Lake Throssell is designed to establish if the tenor of surface mineralisation, averaging 11 800mg/L SOP and up to 14 800 mg/L SOP11, can be reproduced in the sub-surface aquifer (as is the case at the company’s Lake Rason SOP project which has an Inferred Mineral Resource of 6 Mt of SOP, located further to the south).

The 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 to the north and south of the main playa area. This interpreted aquifer system will be targeted with up to 30 offlake air-core drill holes as soon as project access is re-established.

Trigg Mining’s Managing Director, Keren Paterson, said: “This week’s announcement from the WA Government regarding upgrades to the Great Central Road further highlight the outstanding position of the Lake Throssell sulfate of potash project in a world-class mining province just east of Laverton, with high-quality infrastructure and excellent access. The Great Central Road runs adjacent to and right through our tenements, so we are delighted to see this investment in upgrading and enhancing this key piece of regional transport infrastructure.

“On other fronts, with the phased lifting of Covid-19 travel restrictions, our exploration team is hard at work preparing for the maiden air-core programme at Lake Throssell. The Program of Work is approved by the Department of Mines, Industry Regulation and Safety, and we are meeting with the Traditional Owners to agree a forward pathway. All going well, we hope to be back in the field within weeks and on the ground drilling in July. We also have contingency plans in place in the event of any unexpected delays, and we look forward to keeping the market informed as our plans progress in the days and weeks ahead.”
