Following recent gravity surveys, “significant growth potential” has been identified across Trigg Mining’s (ASX: TMG) sulphate of potash (SOP) projects near Laverton in Western Australia.
Trigg managing director Keren Paterson said the gravity survey results had “well and truly exceeded expectations”.
She said the results demonstrate the potential for a multi-decade, tier one SOP production hub based around the company’s flagship Lake Throssell asset.
A maiden 221 line-kilometre survey was completed over the Lake Yeo greenfields SOP project, which is immediately to the south of Lake Throssell and encompasses 1,915sq km of tenements.
Survey data has identified an 80km-long palaeovalley that is up to 3.5km wide and extends 100m deep.
“We are planning to drill Lake Yeo later this year to evaluate the potential of what is clearly emerging as a significant pipeline growth opportunity that can build on the strong base we have established at Lake Throssell,” Ms Paterson noted.
Lake Throssell upside
Meanwhile, over at the Lake Throssell, an infill 216 line km ground gravity survey was undertaken and combined with earlier gravity data and geological modelling to build a high-resolution data set.
This data will be used for interpretation and optimised targeting for upcoming aircore and test production bore drilling programs.
Ms Paterson said the work at Lake Throssell had “revealed further upside potential” and extended the interpreted palaeovalley within the granted tenements – representing an “exceptional growth target” along strike of the existing resource.
“The growth potential for Trigg’s SOP pipeline outlined today is even more critical than ever for global food security given actual and potential geopolitical disruptions to global fertiliser supply chains,” Ms Paterson explained.
Lake Throssell covers 1,085sq km of tenements and is 180km east of Laverton.
The project has a current drainable mineral resource estimate of 14.4 million tonnes of SOP, plus an additional exploration target.
A scoping study that was published in October last year estimated Lake Throssell could host a 21-year 245,000t per annum SOP operation.
