- Trigg Mining (TMG) has received final assay results from aircore drilling completed at its wholly owned Lake Throssell Sulphate of Potash Project, east of Laverton in WA
- The results confirm the presence of a consistent and extensive high-grade brine system at Lake Throssell
- The 5623-metre program included 54 holes, with a maximum drill hole depth of 144 metres
- A total of 253 brine samples were submitted, returning high-grade results of up to 5800 milligrams per litre (mg/L) potassium, with an average grade of 4488 mg/L potassium
- The average grade aligns with the upper end of the project’s previously reported exploration target
- Lake Throssell is confirmed as having a broad palaeovalley system up to five kilometres wide and about 100 metres deep, over a 36-kilometre strike
- Looking ahead, a maiden mineral resource estimate for the project is on-track to be completed during the second quarter of 2021
- Trigg Mining shares are up 2.94 per cent, trading at 17.5 cents each
Trigg Mining (TMG) has received final assay results from an aircore drilling program completed at its Lake Throssell Sulphate of Potash (SOP) Project, east of Laverton.
The results confirm the presence of a consistent and extensive high-grade brine system at Lake Throssell.
The expanded 5623-metre program was completed between late November 2020 and February this year — including a six-week suspension due to unfavourable weather — and saw 54 holes drilled, with the maximum drill hole depth being 144 metres.
All up, 253 brine samples were submitted from the program, returning high-grade results of up to 5800 milligrams per litre (mg/L) potassium, or 12.93 kilograms per cubic metre (kg/m3) SOP.
The average grade recorded was 4488mg/L potassium, or 10.01kg/m3 SOP, which aligns with the upper end of the previously reported exploration target.
Ninety-eight per cent of the assays exceeded 4000mg/L potassium (8.92kg/m3 SOP), while 50 per cent exceeded 4500mg/L potassium (10.4kg/m3 SOP) — confirming the extensive high-grade, low variability tenor of brine within the lake’s palaeovalley system.
Drilling confirmed the system to be broad, spanning up to five kilometres wide and about 100 metres deep, over a 36-kilometre strike.
Trigg Mining Managing Director Keren Paterson said “These are hugely encouraging results that confirm that Lake Throssell is a large-scale and remarkably consistent high-grade SOP project.”
“It is particularly pleasing that the average grade of our assays has come in at the very upper-end of our exploration rarget, which provides a strong foundation for the completion of a maiden mineral resource estimate early next quarter,” Keren added.
“We are also looking forward to getting test trenches in place to commence the work to better understand Lake Throssell’s hydrogeological characteristics, which will be an essential input for feasibility studies.”
Trigg is working towards a maiden mineral resource estimate for Lake Throssell, which is on-track to be completed during the second quarter of this year.
Meanwhile, planning is underway for the construction and testing of test trenches on the lake surface and test production bores at depth, to estimate hydrogeological characteristics of the deposit.
Trigg Mining shares are up 2.94 per cent, trading at 17.5 cents at 3:18 pm AEDT.
