Trigg Mining (ASX: TMG) has secured critical native title agreements for its Lake Throssell sulphate of potash project in Western Australia, which enabled the grant of four tenements and expanded the project’s footprint by 235%.
The company secured native title agreements with the land’s traditional owners including the Ngaanyatjarra, and the Nangaanya-Ky peoples.
With native title secured, four strategic tenements were then granted to Trigg. Including the additional tenements, Lake Throssell SOP project now covers 1,085 square kilometres in the region.
The extra tenements also double the SOP strike length from 35km to 70km.
Trigg noted the additional ground also provided optionality for project infrastructure layout and access to ensure an optimal operation at Lake Throssell.
Commenting on the native title agreements and new tenements, Trigg managing director and chief executive officer Keren Paterson said the traditional owners had been “very welcoming” of the company and its plans.
“I am particularly pleased that traditional owners support our vision to be a mining company of the future – producing a natural mineral fertiliser essential for food production, which may also improve the effectiveness of carbon farming as climate change mitigation.”
She added a scoping study for Lake Throssell position it as a potential top 10 global SOP producer with an initial 21-year mine life.
“The grant of this additional tenure increases the potential to expand the project and/or extend the mine life with further exploration.”
Lake Throssell SOP project
Trigg’s Lake Throssell project has a current resource of 14.4 million tonnes grading 10.4 kilograms per cubic metre of drainable SOP.
The project is 350km from Leonora on a sealed road and 900km by rail to Fremantle.
Trigg is evaluating a sustainable mining operation at the project that would involve solar evaporation of saline brines from 110km trenches and up to 112 bores over the mine life.
The SOP will be produced using commercially proven processing technology.
Annual production is estimated at 245,000t to generate earnings before interest tax depreciation and amortisation of $97 million a year.
Trigg is raising up to $3.3 million under a renounceable rights issue to fund exploration and evaluation programs to underpin a prefeasibility study.
Field work will re-start later in the current quarter and will include heritage surveys to pave the way for drilling and data gathering.
