Planning is underway for the 2020 field program, which includes sampling of the surface aquitard, aircore drilling to define the nature and tenor of basal aquifers hosted within the paleochannel and establishing a JORC-compliant mineral resource.
Trigg Mining’s sulphate of potash projects
Focus on Lake Throssell
In the December 2019 quarter, managing director Keren Paterson said: “It has been a significant quarter for Trigg, having completed the $4.5 million IPO, ASX listing and actively exploring across the company’s Sulphate of Potash projects including geophysics surveys, a heritage clearance survey, pit sampling and aircore drilling.
“The results of the programs will allow Trigg to rationalise the large tenure at Laverton Links and focus exploration on the high-grade Lake Throssell SOP Project where the inaugural pit sampling results indicated free-flowing high-grade brines with assay results of up to 14,800 mg/l SOP.
“A mineral resource estimate is underway for the Lake Rason prospect and planning has commenced for the inaugural drilling program at the exciting high-grade Lake Throssell SOP Project.”
Heritage survey work
During the December quarter a heritage clearance survey was carried out with the traditional owners, the Ngaanyatjarra, and this was immediately followed by the inaugural hand auger brine sampling program to assess the tenor of brine within the surface aquitard.
A total of 35 brine samples and duplicates were collected at 16 sites across the project area from a depth of up to 2 metres, with free-flowing brines documented at each sample site.
Lake Throssell comprises one granted tenement and two applications covering 752 square kilometres and encompasses the highly prospective Lake Throssell playa lake and underlying palaeo-channel for more than 100 kilometres in strike length.
Laverton Links SOP Project
The Laverton Links SOP Project comprises three prospects - Lake Rason, Lake Hope Campbell and East Laverton - for a total granted and applied area of 2,424 square kilometres.
These prospects are within a 35 kilometres to 225 kilometres radius east of Laverton, Western Australia, and nearby the Tropicana Gold Mine.
During the December quarter, Trigg entered into an agreement to purchase an additional tenement, E38/3437 (96 square kilometres) for $20,000, payable in shares upon grant and applied for a further tenement, E38/3464, immediately to the west of the previous tenements, adding approximately 31 square kilometres of playa surface.
The additional tenure at Lake Rason almost entirely secures the Lake Rason paleo-system and has the potential to enhance the anticipated mineral resource estimate following completion of sampling and drilling programs.
