HIGH-GRADE DISCOVERY AT LAKE THROSSELL

arrow-down-2 Created with Sketch.

High-Grade Sulphate of Potash Discovery at Lake Throssell

ASX Announcement 16 December 2019



Lake Throssell Sulphate of Potash Project


High-grade discovery at Lake Throssell:

  • Hand-auger brine samples returned high grades of up to 6,660 mg/L potassium (K) or 14.8 kg/m3 SOP

equivalent.

  • Average grade of 5,296 mg/L potassium, or 11.8 kg/m3 SOP equivalent from 18 samples.

Planning is underway to target the basal sand aquifer of the palaeochannel in 2020 including geophysical

surveys and exploration drilling.


Trigg is in the unique position of having:

  • 100% ownership of this significant sulphate of potash salt lake system covering 752 km2 and 106 km of

trend.

  • Major transport infrastructure adjacent to the Project and only 20 km from the Yamarna Gas Pipeline.


Trigg Mining Limited (ASX: TMG) (Trigg or the Company) announces the results of the initial hand-auger

sampling program over Lake Throssell, establishing the potential for a high-grade deposit with potassium results

of up to 6,660 mg/L K with an average grade of 5,296 mg/L K (or 11.8 kg/m3 SOP). The samples exhibit

favourable characteristics for solar evaporative concentration and lower waste salts with a low Na:K ratio of

15.5:1 and a high SO4 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 Mineral

Resource.


This early indication of the potential mineralisation has led the Company 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 km2 and it is all prospective for SOP mineralisation with a

106 km trend.


Managing Director, Keren Paterson commented, “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.”

FIRST SAMPLES COLLECTED

arrow-down-2 Created with Sketch.


 First samples collected from highly prospective Lake Throssell and new tenements applications double the Project area.

ASX Announcement 2 December 2019


Lake Throssell Sulphate of Potash Project 

  • Heritage survey completed. 
  • Hand-auger sampling targeting near-surface brines conducted.
  • Auger holes rapidly filled with brine from 30 to 70cm below surface with abundant gypsum indicating the brine is saturated in sulphate. 
  • 35 samples from 16 locations collected for analysis from across the lake surface with assay results expected in Q3 FY20. 
  • Two new tenement applications that cover approximately 434km2 along the northern and southern extensions of the interpreted underlying palaeochannel, securing the Lake Throssell system and taking the Project area to 752km2

The next phase of exploration to target the basal sand aquifer of the palaeochannel.


Laverton Links Sulphate of Potash Project

  • Ground gravity surveys completed at both Lake Hope Campbell and East Laverton. 
  • 20 exploration drill holes completed for 1,463m of air core drilling at Lake Hope Campbell.
  • Palaeochannel sediments encountered throughout the tenement extent, basal sand and gravel present at up to 40m in thickness with strong brine flows from airlifts. 
  • Assay results expected early in Q3 FY20. 
  • Aircore drilling now underway at Lake Rason with results expected 
  • Initial JORC Mineral Resource estimates anticipated Q3 FY20. 


 Trigg Mining Limited (ASX: TMG) (Trigg or the Company) has completed three significant in-field exploration milestones at its two Sulphate of Potash (SOP) Projects near Laverton in Western Australia, just weeks after listing on the ASX. The completion of the heritage survey with the Ngaanyatjarra traditional owners at the Lake Throssell SOP Project paved the way for the very first SOP sampling program across Lake Throssell with results expected early in the next quarter. The early positive signs of the potential mineralisation have led the Company to apply for two additional tenements to the north and the south of Lake Throssell along the interpreted underlying palaeochannels, securing the palaeo-system and taking the Project area to 752km2. The results from the sampling program are expected early next quarter.


At Laverton Links the first drilling program at Lake Hope Campbell has also been completed with 1463m of air core drilling across 20 holes testing the entire 100km of the palaeochannel. Drilling targeted the gravity lows detected by the recently completed ground gravity survey in combination with the existing publicly available aerial electromagnetic (AEM) survey. The drilling encountered traditional Goldfields style palaeovalley sediments including a lacustrine clay aquitard up to 50m thick and basal sand and gravel aquifer beneath the clay up to 40m thick. 

The drill rig has now moved to Lake Rason where 500 m of drilling is planned to supplement the previous air core drilling results and will allow for an initial Mineral Resource estimate to be calculated.


Lake Throssell Sulphate of Potash Project 

The Lake Throssell Sulphate Potash Project (Lake Throssell) lies approximately 200km east of Laverton along the Great Central Road (through to Queensland) and covers approximately 752km2 of tenements including the Lake Throssell playa lake and underlying palaeochannel. In 2017 Trigg and the Ngaanyatjarra traditional owners entered into an exploration access agreement and under this agreement a heritage survey has now been completed paving the way forward for on-ground exploration activities. 

Reconnaissance sampling was completed immediately after the heritage survey, collecting the very first brine samples from the lake to determine the tenor of the brine throughout the surface aquitard. A hand auger was used to establish pits up to 2m in depth and free-flowing brine was encountered 30 – 70cm below surface in all 16 pits (Figures 1 and 2 and Table 1). 35 samples were taken for analysis with results expected early in Q3 FY20. 

Abundant gypsum was encountered over the lake area (Figure 1), indicating super-saturation of sulphates and is considered a good early indicator of the potential of the mineralisation within the brine. This observation also confirms the ASTER satellite gypsum index imagery across the lake surface (Figure 2). 

With such strong indication of the potential for mineralisation across the Lake Throssell area, the Company has applied for two additional tenements along the interpreted underlying palaeochannel to the north and south, securing the Lake Throssell palaeo-system. Together these tenements cover an additional 434km2 of potential SOP mineralisation (Figure 3), taking the Lake Throssell Project area to 752km2. 

The next phase of exploration at Lake Throssell will target the palaeochannel and the basal sand aquifers.


Laverton Links Sulphate of Potash Project 

Lake Hope Campbell 

The first air core drilling program at Lake Hope Campbell has been completed with 1463m drilled across 20 holes (Table 2), testing the entire 100 km strike length of the tenement area. Drilling targeted the gravity lows detected by the recently completed ground gravity survey in combination with the existing publicly available AEM survey. Three drill transects were completed over the palaeovalley sequence to confirm the geometry of the channel sediments, additional single drill holes were completed on the remaining gravity lines and AEM targets where accessible. The drilling encountered traditional Goldfields style palaeovalley sediments including a lacustrine clay aquitard up to 50m thick and basal sand and gravel aquifer beneath the clay up to 40m thick. The end of holes typically encountered a granitic basement with an overlying weathered profile. 

Brine and lithological samples will be submitted for analysis with results expected early in Q3 FY20.


Managing Director, Keren Paterson commented, “In just a few weeks since listing we have completed multiple significant milestones. At Lake Throssell - a heritage survey, reconnaissance sampling and additional tenement applications covering the Lake Throssell system have been completed. At Laverton Links we’ve finished the first drilling program at Lake Hope Campbell which encountered multiple intersections of up to 40m of basal sands and gravels. Assay results for the sampling programs are expected next quarter and initial mineral resource estimates to follow. 

I would like to take this opportunity to extend our gratitude to the of the Ngaanyatjarra, traditional owners of Lake Throssell, for their support in helping us to achieve the heritage clearance and for the cultural exchange we experienced. 

The field program will continue over the next few weeks with further drilling planned at Lake Rason and East Laverton and I look forward to keeping the market up to date on our rapid progress across both Projects with assay results and initial mineral resource estimates due next quarter.”
