Trigg Mining Moves Lake Throssell to Next Stage

THE DRILL SERGEANT: Trigg Mining (ASX: TMG) has wasted little time in moving to the next stage of evaluation and development of the company’s 100 per cent-owned Lake Throssell sulphate of potash (SOP) project in Western Australia.

Trigg Mining released a maiden Inferred Mineral Resource estimate just last week of 14.2 million tonnes of drainable SOP and has now commenced a lake surface trenching and test pumping program.

The program follows on from drilling campaigns that established the presence of a high-grade brine deposit within the lake surface and the entire palaeovalley sequence.

The trenching and test pumping program is designed to enable estimates of drainable porosity and permeability of the surficial aquifer to be calculated.

The program includes seven test pit locations and two 100m long trial trenches, with associated monitoring pits.

Pumping from the trial pits and trial trenches will create draw-down of the water table in the surrounding sediments which can be measured by the monitoring pits, with the rate and magnitude of the draw-down used to estimate drainable porosity and permeability of these sediments.

“We’re excited to be back in the field so quickly with the trenching and pump testing program now well underway,” Trigg Mining managing director Keren Paterson said in the company’s ASX announcement.

“The data which we will gather from these work programs will be a crucial input for calculating an Indicated Mineral Resource for the surficial aquifer and in estimating potential flow rates, which will help to establish the economic parameters that will underpin our Scoping Study.

“Having a higher-confidence Indicated Resource will be an important de-risking step for the project and will also form the basis of our planned Scoping Study commencing in the second half of this year.

“Production flow rate data will help us to establish the potential production profile and, ultimately, economic and financial features of the project.

“Following our recently announced maiden Inferred Mineral Resource, this represents another really important step forward towards creating a major new sulphate of potash production hub at Lake Throssell.”

Trigg Mining Reports Maiden Lake Throssell SOP Resource

THE DRILL SERGEANT: Trigg Mining (ASX: TMG) stamped its credentials for developing a new long-term sulphate of potash (SOP) production hub in the Laverton district of Western Australia with delivery of a substantial maiden Inferred Mineral Resource Estimate (MRE) for the company’s Lake Throssell SOP project in Western Australia.

Trigg Mining reported a Drainable Inferred Mineral Resource for Lake Throssell of 14.21 million tonnes SOP at 4,638mg/L potassium (K) (or 10.34kg/m3 potassium sulphate [K2SO4]) has been estimated based on results from thorough exploration programs completed at the project.

The company explained the only additional data required to increase the confidence category of the MRE to Indicated is test pumping to evaluate additional aquifer properties.

The company also updated its Exploration Target, which it said indicates strong potential to expand this MRE.

The new Exploration Target, in addition to the MRE, has been defined as a range of 2.6 to 9.4 million tonnes at 9.5 to 10.3kg/m3 K2SO4.

“This is a fantastic result for our shareholders which puts Trigg Mining front and centre of the new-generation SOP industry in Western Australia,” Trigg Mining managing director Keren Paterson said in the company’s ASX announcement.

“The maiden 14.2 million tonnes at 10.3kg/m3 SOP Mineral Resource clearly shows that Lake Throssell has the scale and grade to underpin a sustainable long-term SOP production hub, particularly when considering its Tier-1 location and proximity to high-quality energy and transport infrastructure.

“In addition to delivering a sizeable maiden Mineral Resource, we have also demonstrated the upside potential with an updated Exploration Target of 2.6 to 9.4 million tonnes of SOP, encompassing tenements to the north and south which are awaiting grant.

“Together with our Lake Rason project, the company now has a Total Mineral Inventory of more than 20 million tonnes of SOP with substantial upside to expand on this even further.

“The publication of a maiden Mineral Resource for Lake Throssell marks the beginning of an exciting journey for Trigg.

“We will immediately start the next phase of work, which includes a program of trenching and test pumping aimed at converting a portion of the Inferred Mineral Resource to the higher confidence Indicated category.

“This will in turn provide the foundation for a Scoping Study, which we are aiming to complete by the end of this year.”

Trigg Mining Confirms Extensive High-Grade Brine System at Lake Throssell

THE DRILL SERGEANT: Trigg Mining (ASX: TMG) reported assay results from a recently completed air-core drilling program at the company’s 100 per cent-owned Lake Throssell sulphate of potash (SOP) project, located east of Laverton in Western Australia.

Trigg Mining described the results from the expanded 54-hole program as being, “highly encouraging” with 253 brine samples submitted for assay, returning high-grade results of up to 5,800mg/L potassium (12.93kg/m3 SOP), with an average grade of 4,488mg/L potassium (10.01kg/m3 SOP).

Of note, 98 per cent of assays exceeded 4,000mg/L potassium (8.92kg/m3 SOP) and 50 per cent exceeded 4,500mg/L potassium (10.04kg/m3 SOP), confirming the extensive high-grade, low variability tenor of the brine within Lake Throssell palaeovalley system.

The drilling also confirmed the presence of a broad palaeovalley of up to 5km wide and about 100m deep over a strike of 36km.

Trigg Mining has now commenced work on a maiden Mineral Resource Estimate, which is on track to be completed in Q2 2021.

“These are hugely encouraging results that confirm that Lake Throssell is a large-scale and remarkably consistent high-grade SOP project,” Trigg Mining managing director Keren Paterson said in the company’s ASX announcement.

“It is particularly pleasing that the average grade of our assays has come in at the very upper-end of our Exploration Target, which provides a strong foundation for the completion of a maiden Mineral Resource estimate early next quarter.

“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 Mining Drills Path to Lake Throssell JORC Resource

THE DRILL SERGEANT: Trigg Mining remains on track for a maiden JORC Resource at the company’s e 100 per cent-owned Lake Throssell sulphate of potash (SOP) project, located east of Laverton in Western Australia.

Trigg Mining had expanded the program from its original 38 holes to 54 holes, on the back of results achieved during the first stage of the program.

The recent program has covered the palaeovalley extent within tenement E38/3065 covering a strike length of approximately 36 kilometres of the 112km in the total project area.

Field analysis of salinity has indicated the recently drilled southern portion of the palaeovalley has comparable salinity to the northern portion where assay results returned grades of up to 11,519mg/L (11.5kg/m3) SOP equivalent.

Brine samples have been submitted to laboratory for analysis, with results expected at the end March / early April.

Geological modelling has commenced for a maiden JORC Inferred Mineral Resource estimate, which is expected to be completed next Quarter.

“The completion of our first-ever comprehensive air-core program at Lake Throssell is a significant milestone for the team and an important step towards unlocking the commercial potential of this large-scale, high-grade sulphate of potash deposit,” Trigg Mining managing director Keren Paterson said in the company’s ASX announcement.

“We are encouraged and excited by what we have seen in the drilling so far, with preliminary observations from the field confirming that we have a very large-scale palaeovalley system extending over a strike length of 36km within granted tenement E38/3065, up to 5km wide and up to 100m deep.

“Importantly, there is clear evidence of the presence of multiple aquifers across the profile – which suggests the potential for multiple production sources.

“We are now eagerly awaiting assay results from the drilling and work has already commenced on the geological model required to underpin a maiden JORC Mineral Resource estimate, which we expect to complete next quarter.

“This will provide a foundation for economic studies and is only the beginning of the resource story at Lake Throssell with roughly two thirds of the strike potential within the current project area still untested.

“We are continuing our systematic approach to unlocking the potential of this exciting high-grade sulphate of potash project, and we are looking forward to delivering a significant amount of news-flow for our shareholders and investors over the next few months.”

Trigg Mining Declares Lake Throssell Target

THE CONFERENCE CALLER: If there is one compelling reason to invest in specialist sulphate of potash (SOP) explorer Trigg Mining (ASX: TMG) it’s that people have to eat. By Mark Fraser

Describing itself as a modern, purpose-driven exploration house set on helping to deliver global food security, Trigg plans to employ a sustainable “mining” method – the solar evaporation of hyper-saline brine – to produce a SOP premium mineral fertiliser essential for the production of high value agricultural products.

The company controls around 1,585 square kilometres of tenure covering two projects in Western Australia’s north eastern Goldfields, which includes 380 square kilometres of playa lakes and 140km of paleochannels – all of which are prospective for SOP mineralisation.

These projects lie near the terminus of extensive palaeovalley catchment areas
(ancient river valleys) which extend for over 500km and are underlain by potassium-bearing source rocks (namely granites, sandstones and salt diapirs).

Here, brine solutions carrying potassium mineralisation have been concentrating in
the palaeovalleys and salt lakes (evaporite systems) for millions of years.

Trigg’s flagship project, the high-grade Lake Throssell, covers 1,085sqkm and has around 70km of interpreted palaeovalley extent.

So far the highest SOP grade discovered in this tenure has been 14,800 milligrams per litre, while the initial results for the current air core drilling program – drilled to a depth of up to 130 metres – returned an average grade of 9,772 milligrams per litre.

Furthermore, 92% of all samples taken to date have revealed grades exceeding 9,000 milligrams per litre, while 64% are over 10,000 milligrams per litre.

Meanwhile, the junior’s second project – Lake Rason – is currently being seen as a potential satellite ore body.

It covers 500sqkm and includes 194sqkm of playa lake and 64km of interpreted palaeovalley.

Importantly, it already has an inferred mineral resource of 6 million tonnes at 5,080 milligrams per litre SOP and the potential to increase volume and grade to the west, with the western-most hole drilled (LRTAC001) returning results of up to 6,645 milligrams per litre.

Just before appearing at the RIU Explorers Conference in WA, the company announced that recent exploration success had enabled a sizeable initial high grade exploration target to be estimated at Lake Throssell, with outstanding growth potential.

This target was approximately 7.5 to 27 million tonnes at a grade ranging between 9,000 and 10,000 milligrams litre SOP equivalent and covered a strike length of around 70km of the interpreted palaeovalley within a total strike length of about 112km under tenure – including adjacent tenements under application.

Trigg said high grades and multiple potential aquifers were encountered throughout the profile, meaning that trenching and the establishment of deep production bores were possible.

Earlier this month the company also announced that 2021 air core drilling at Lake Throssell, where field work completed in 2020 within the northern half of the project area (16 holes for 1806m representing some 40 per cent of the program), confirmed the presence of a broad palaeovalley at least 1km wide, with some areas potentially broadening up to 3-4km wide.

Assay results were positive, returning high grades of up to 11,519 milligrams per litre SOP (or 11.5 kilograms per cubic metre) with an average grade of 9,772 milligrams per litre SOP.

During her appearance at the RIU conference, Trigg managing director and chief executive Keren Peterson said the company was looking to establish a maiden JORC resource in the second quarter of 2002.

“So that (February 16) announcement – that exploration target – has us very excited because it is substantial,” she noted.

“This is a project that has never had any drilling done until we got out there (last) July.

“And it’s taken a fair bit of innovation … because it is of substantial scale.

“It’s going to be big. It’s going to have a long life when we bring it into production, and it’s got the grade to do that.”

Petersen said SOP was an essential fertiliser for high value, chloride sensitive crops like fruit, vegetables, avocados, coffee beans, grapes, tree nuts, cocoa and anything grown under glass and in arid and acidic soils.

In addition, with the natural endowment of the minerals dissolved in brine and the ability to harvest solar evaporation to produce SOP, brine producers were generally low cost ones.

 

 

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.”

Trigg Mining Commences Lake Throssell Sulphate of Potash Drilling

THE DRILL SERGEANT: Trigg Mining (ASX: TMG) commenced a program of air-core drilling program at the company’s 100 per cent-owned Lake Throssell Sulphate of Potash (SOP) project, located east of Laverton in Western Australia.

Due to a late start to the planned program due to the high level of competition for drilling resources across WA in the second half of 2020, Trigg Mining expects to announce a maiden Mineral Resource estimate, subject to results, in the first Quarter of 2021.

The air-core drilling, being the first-ever holes to be drilled to depth at Lake Throssell, will comprise up to 38 core holes targeting the basal aquifer, interpreted by the company to be around 130 metres below surface based on the interpretation of gravity-gravity surveys.

The basal aquifer is expected to lie within the deepest part of the palaeovalley known as the ‘thalweg’, which is interpreted to be up to 2km wide in places and extends for up to 46km within the current granted tenement and up to 80km through the project area.

“We are very excited to be drilling the basal aquifer at Lake Throssell, which has been the company’s primary focus since acquiring the SOP projects and listing on the ASX in October last year,” Trigg Mining managing director Keren Paterson said in the company’s announcement to the ASX.

“The results of this program are expected to provide sufficient detail to calculate an Inferred Mineral Resource estimate for Lake Throssell, which 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.”

Trigg Mining Expands Lake Rason System

THE DRILL SERGEANT: Trigg Mining (ASX: TMG) announced it has received results of drilling carried out in December 2019 over the company’s Laverton Links sulphate of potash (SOP) project in Western Australia.

Trigg Mining reported the results include the intersection of a 52 metres-thick sequence on sands and conglomerates on the periphery of the previously defined Lake Rason system.

This was achieved by hole LRATC001a from 44 metres with an average grade of 2,350 milligrams per litre (mg/l) potassium (or 5,230mg/l Sulphate of Potash (SOP) equivalent).

Elsewhere, scout drilling along the Lake Hope Campbell trend identified multiple thick basal sand aquifers with a peak intersection of:

LHCACT018
11m at 2,330mg/l potassium (or 5,200mg/l SOP equivalent) in from 59m.

Trigg’s 2019 aircore drilling program at Lake Hope Campbell is the first known drilling over this 106-kilometres interpreted palaeochannel trend.

The company declared it has intercepted deep palaeochannel sands and gravels over multiple holes with transects of up to 1,300mwide.

These zones are also expected to have high permeability based upon Trigg’s field observations.

The results from this program, in addition to the program completed in 2017 at Lake Rason, will be included in a Mineral Resource estimate expected later this quarter.

“The 2019 drilling program tested the extent of the Laverton Links SOP Project and confirmed the extension of the mineralisation at Lake Rason,” Trigg Mining managing director Keren Paterson said in the company’s announcement to the Australian Securities Exchange.

“At Lake Hope Campbell several thick basal sand aquifer units with potassium grades up to 2,330mg/l potassium were encountered with palaeochannel widths of up to 1,300 metres.

“The results achieved from across the Laverton Links potash project will allow Trigg to rationalise the large tenure and focus attention on the high-grade Lake Throssell potash project and the more significant areas of Laverton Links.”

Trigg Mining

THE CONFERENCE CALLER: Trigg Mining’s ambitions lie in securing Australia’s sustainable agriculture future through the exploration of the essential potassium fertiliser, sulphate of potash (SOP).

Trigg is looking to establish a domestic source of SOP, given that currently Australia imports all its potassium fertiliser needs, often from as far away as Canada and Germany, despite potassium-rich brines being known to exist in the desert regions of Western Australia.

“This is mining in name more than anything else, because it is an evaporation-style mineralisation,” Trigg Mining managing director Keren Paterson said.

“It’s about agricultural mineralisation and food supply…we have been out speaking with farmers in Western Australia, because our projects are very close to the WA agricultural sector, so it’s important to understand the needs of our farmers and the people who produce our food.

“We have resources here in Australia and we can’t wait to define what potentially will be ours and to engage with the farmers of Western Australia and Australia as a whole.”

Trigg Mining has built a competitive footprint across two SOP Projects in the Goldfields of WA: the Laverton Links and Lake Throssell potash projects.

The company stated aim is the exploration for naturally occurring SOP, found in potassium-rich hypersaline brine water, which provides two essential elements for plant growth and human nutrition – potassium and sulphur.

Beside from its ability to provide these two important macro nutrients, the other important characteristic of SOP is that it contains very little chloride which is detrimental to many crops such as fruit and vegetables including avocados, cocoa, coffee beans, grapes, berries and tree nuts, as well as arid and acidic soils.

The sustainability factor stretches to the production of SOP, which can be achieved through the solar evaporation of potassium-rich hypersaline brine water, without the need for large open pits or waste-rock dumps.

“it’s very simple exploration,” Paterson continued.

“It’s aircore drilling that is shallow as we are exploring for the water – the minerals are already dissolved in the water.”

Trigg Mining’s SOP projects do just this and extend the company’s ambitions by being located approximately 200 kilometres east of Laverton in Western Australia close to established energy and transport infrastructure for access to Australian and international agricultural markets.

The projects cover more than 3,000 square kilometres and contain over 400sqkm of salt lake playa and 375km of interpreted palaeochannels (ancient underground rivers), all of which are considered by the company to be highly prospective for brine hosted SOP.

Just as 2019 was coming to a close, Trigg Mining announced a new discovery of high-grade SOP at its Lake Throssell SOP project.

The discovery came via hand-auger brine samples that returned high-grades of up to 6,660 milligrams per litre (mg/L) potassium or 14.8 kilograms per cubic metre (kg/m3) SOP equivalent.

An average grade of 5,296mg/L potassium, or 11.8kg/m3 SOP equivalent was achieved from 18 samples.

The results set Trigg to the drawing board to immediately plan activities to target the basal sand aquifer of the palaeochannel in 2020, including geophysical surveys and exploration drilling.

The company plans an initial air core drilling program in 2020 to map and sample the underlying palaeochannel in conjunction with additional near-surface sampling, with the aim of establishing an initial JORC Mineral Resource.

The early indication of potential mineralisation 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, taking the project area to 752sqkm, all of which it considers prospective for SOP mineralisation with a 106km trend.

“The Lake Throssell Sulphate of Potash project is shaping up to be a significant SOP project,” Paterson said.

“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.”

Trigg struck an agreement to purchase a tenement covering the western portion of Lake Rason, paying $20,000 for exploration licence E38/3437.

The tenement is not expected to be granted until Q3 FY20, however Trigg believes the additional ground in the Lake Rason area has the potential to enhance the anticipated Mineral Resource estimate following completion of sampling and drilling programs with 10km of direct lake trend to be added to the existing 42km lake trend.

Early exploration work carried out by the company has established a JORC Code-compliant Exploration Target at the Lake Rason prospect and identified the palaeochannel and SOP mineralisation at the Lake Hope Campbell prospect.
