Trigg Mining Confirms Lake Throssell SOP Potential

THE DRILL SERGEANT: Trigg Mining (ASX: TMG) reported encouraging initial assay results from partially completed maiden air-core drilling underway at the company’s 100 per cent-owned Lake Throssell Sulphate of Potash (SOP) project, located east of Laverton in Western Australia.

The drilling, which was confined to the northern half of the project area, has confirmed the presence of a broad palaeovalley at least 1km wide and potentially up to 3-4km wide in places.

A total of 74 brine samples collected during this first phase of drilling were submitted before Christmas for analysis, with results returning high grades of up to 11,519mg/L SOP (11.5kg/m3 ) with an average grade of 9,772mg/L SOP

The brine chemistry also suggests favorable characteristics for solar evaporation concentration and lower waste salt levels, with a low Na:K ratio and high SO4 concentration.

Air-core drilling is scheduled to recommence in late January 2021 (weather permitting), with assay results from the remainder of the drilling expected by early March.

A maiden JORC Mineral Resource Estimate is expected to be released next Quarter once the air-core drilling is complete and all results have been received and analysed.

The company has commenced work to estimate a maiden JORC Exploration Target for the Lake Throssell project, based on all available data gathered to date.

“We are pleased to have started the New Year with excellent assay results from the brine samples submitted to the laboratory prior to Christmas,” Trigg Mining managing director Keren Paterson said in the company’s ASX announcement.

“This provides the first definitive indication that we have a high-grade sulphate of potash discovery at Lake Throssell in both the surficial aquifer and the underlying palaeovalley.

“Subject to access and weather conditions, we expect to be drilling again shortly at Lake Throssell to complete the balance of the air-core program.

“In the interim, we have started work on a maiden Exploration Target and we expect to be in a position to complete our maiden JORC Inferred Mineral Resource next quarter.

“This will be the second Mineral Resource estimate for the company since listing – putting Trigg Mining on a clear path towards the development of a significant new Sulphate of Potash production hub east of Laverton in Western Australia.”
