Trigg Mining to receive infrastructure boost for Lake Throssell SOP Project from road sealing

The Great Central Road Project will create Australia’s third transcontinental highway, providing a sealed route from WA to Winton in Queensland and reduce transport and logistics time and cost between the two important centres of mining and agriculture.

The lifting of interstate travel restrictions clears the way for the company's Lake Throssell exploration plans

Trigg Mining Ltd (ASX:TMG) welcomes a WA State Government and Federal Government announcement of the sealing of a 41-kilometre section of the Great Central Road which will benefit the Lake Throssell Sulphate of Potash (SOP) project.

This road is a key arterial route that runs from Leonora and Laverton towards Trigg's high-grade project and the $20 million road sealing contract will provide an infrastructure boost to the company.

Managing director Keren Paterson said: “This week’s announcement from the WA Government regarding upgrades to the Great Central Road further highlights the outstanding position of the Lake Throssell SOP 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.”

The road improvement project represents a benefit to the future development of the Lake Throssell project and is expected to improve project access and future logistics in terms of the transport of people, equipment, materials and product to and from the project.

Travel restrictions lifted

The WA Government also announced a further phased lifting of intrastate travel restrictions which is expected to clear the way for the resumption of field activities and for the company’s maiden exploration aircore drilling program to begin next quarter.

Paterson said: “With the phased lifting of COVID-19 travel restrictions, our exploration team is hard at work preparing for the maiden aircore program at Lake Throssell.”

Meetings are scheduled with the Ngaanyatjarra, the Traditional Owners of the Lake Throssell Project, to discuss access arrangements for the company’s field exploration teams.

Paterson said: “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.”

In the event of any unforeseen delays, the company’s exploration team is also considering including a limited helicopter-supported exploration program which will allow it to progress the next phase of activity in the short term.

Drilling plans

A recent gravity survey at Lake Throssell defined several targets which are highly prospective for high-grade SOP endowment.

Trigg believes that these targets have strong potential for large-scale SOP mineralisation, particularly given that similar systems in the region are subject to mining studies.

The upcoming drilling program is designed to establish if the tenor of surface mineralisation, averaging 11,800 milligrams per litre SOP and up to 14,800 milligrams per litre SOP11, can be reproduced in the sub-surface aquifer - as is the case at the company’s Lake Rason SOP Project.

The off-lake ground gravity survey undertaken in March 2020 identified several strong indicators of a palaeovalley underneath the lake surface and this interpreted aquifer system will be targeted with up to 30 off-lake aircore drill holes as soon as project access is re-established.
