Trigg Mining Ltd - Trigg Mining shares rise after revealing high-grade potassium results from Lake Throssell
Planning has commenced to enable an initial air core drilling program in 2020

Trigg Mining Ltd (ASX:TMG) has confirmed a high-grade sulphate of potash (SOP) discovery from its initial hand-auger sampling program over the Lake Throssell Project in WA.

The company has established the potential for a high-grade deposit with results of up to 6,660 milligrams per litre (mg/L) potassium with an average grade of 5,296 mg/L potassium.

The samples exhibit favourable characteristics for solar evaporative concentration and lower waste salts with a low sodium to potassium ratio of 15.5:1 and a high sulfate concentration.

This brine composition is comparable to peers who have produced high-grade SOP samples indicating equivalent process techniques can be used.

Planning has commenced to enable an initial air core drilling program in 2020 to map and sample the underlying palaeochannel; as well as additional near-surface sampling, with an aim to establishing an initial JORC resource.

This early indication of the potential mineralisation has led Trigg to apply for two new tenements to the north and the south of Lake Throssell along the interpreted underlying palaeochannel, securing the Lake Throssell system.

This takes the project area to 752 square kilometres and it is all prospective for SOP mineralisation with a 106-kilometre trend.

Trigg managing director Keren Paterson said: “The Lake Throssell Sulphate of Potash Project is shaping up to be a significant SOP project.

“These high-grade results across the playa and the potential scale of the underlying palaeochannel makes this discovery one of the most important for Australia’s emerging SOP industry and our nation’s food security.”
