MetalsGrove Mining has RC drill spinning in maiden Box Hole and Edwards Creek program in NT

MetalsGrove Mining Ltd (ASX:MGA) has set the reverse circulation (RC) drill spinning in maiden drilling testing the Box Hole zinc-lead and Edwards Creek copper-gold prospects within the Arunta Project in the Northern Territory.

The critical metals exploration and development company says the 2,400-metre program will test several high-priority targets including stratabound mineralisation.

These targets have been generated by Intrepid Geophysics, which has processed and overlaid significant historical geochemistry, electromagnetic and radiometric data sets.

Next phase begins

Managing director Sean Sivasamy said: “We are very pleased to have this next phase of drilling underway within our Arunta Project.

“Given the recent completion of RC drilling at our highly prospective Bruce REE Prospect, we have utilised the availability of the drill rig to carry out this next phase of work at Edwards Creek and Box Hole.”

The maiden drilling program at Box Hole and Edwards Creek is expected to take around three weeks to complete with first assays to be reported within 4-6 weeks thereafter.

Box Hole follow-up

Historical drilling at Box Hole returned a best intersection of 13 metres at 2.7% zinc and 0.7% lead from 17 metres including 5 metres at 2.3% zinc and 1.4% lead, and 5 metres at 4.3% zinc and 0.2% lead from 25 metres. The latter included 1-metre at 14.7% zinc and 0.3% lead from 25 metres.

The Box Hole zinc-lead, REE prospect comprises a single granted mineral exploration licence covering about 12,765 hectares and is about 340 kilometres northeast of Alice Springs.

At the prospect’s Kings Working deposit, 15 tonnes of galena was historically mined with an average grade of 66% lead, 58.50 g/t silver and 0.43% bismuth.

The known outcrop at Box Hole has a strike extent of 7 kilometres with mineralisation open in all directions.

This previous work and MetalsGrove’s reconnaissance have led to a conceptual exploration target of between 50 and 80 million tonnes at a grade ranging between 3.0% to 4.0% zinc-lead and at a shallow depth.

Edwards Creek program

Previous work at Edwards Creek, which covers around 380 square kilometres about 75 kilometres NNE of Alice Springs in the highly prospective Arunta region, has also provided encouragement for MetalsGrove heading into the RC campaign.

Historical drilling returned high-grade mineralisation including 4.5 metres at 2.25% copper, 0.11% lead, 1.54% zinc and 0.14 g/t gold from 47 metres and 18.6 metres at 0.22% copper, 0.17% lead, 0.49% zinc and 0.14 g/t gold from 44.3 metres.

Territory Exploration Pty Ltd acquired new EM data over Edwards Creek in 2017 and identified a strong EM conductor that was interpreted to be caused by sulphide mineralisation at depth.

Two RC holes were drilled to test the conductor intersecting relatively weak zones of copper mineralisation with a maximum value of 0.81% copper.

Systematic exploration

“Our Arunta Project is a highly prospective asset located in a prime exploration jurisdiction and we are committed to unlocking its value through continued systematic exploration over the coming months,” Sivasmy continued

“Box Hole and Edwards Creek are excellent prospects, with significant discovery potential as demonstrated by historical exploration data and recent reconnaissance work completed by MGA.”

The following are the latest updates from MetalsGrove’s projects:

Upper Coondina Lithium Project – WA

Upper Coondina is a lithium, tin and tantalum project in the highly prospective Pilbara Mineral Field in Western Australia.

The project is near lithium and tantalum producers including Pilbara Minerals Ltd (ASX:PLS) (Pilgangoora Project), Mineral Resources Ltd (ASX:MIN) (Wodgina) and Global Lithium Resources Ltd (ASX:GL1).

Surface mapping and sampling at Upper Coondina have confirmed multiple outcropping pegmatite dykes from 3 to 30 metres wide occurring in swarms.

MetalsGrove’s maiden 4,200 metres reverse circulation (RC) drilling campaign was completed in December 2022 with the first assays due in Q1 2023.

Arunta Project – NT

MetalsGrove has identified advanced rare earth elements (REE), lithium, copper, gold and base metal targets at the Arunta Project in the Northern Territory.

The company is getting ready to start drilling at three priority target areas within Arunta:

  • Bruce Prospect: maiden 3,000-metre drill program to start in Q2 2023 to test the bedrock conductor and historical pegmatite mines;
  • Box Hole Prospect: maiden 2,500-metre drill program to start in Q2 2023 to test the known mineralisation and geophysical targets; and
  • Edwards Creek: maiden 600-metre drill program to start in Q2 2023 to test the known mineralisation down-dip extension and geophysical targets.

Woodie Woodie North Manganese Project – WA

The Woodie Woodie North Manganese Project covers an area of about 13,740 hectares and is adjacent to well-known manganese mines in the Pilbara.

Surface sampling has returned several highly anomalous assays up to 52% manganese with 12 drill-ready walk-up drilling targets defined.

MetalsGrove has planned a maiden 2,500-metre drilling program at Woodie Woodie North in Q3 2023 to test a broad conductor along a major structural corridor.

MetalsGrove Mining completes heritage survey across key Arunta Project tenements

MetalsGrove Mining Ltd (ASX:MGA) has completed a heritage survey across key tenements within the Arunta Project, 10 kilometres north of Alice Springs in the Northern Territory.

This survey was undertaken by members of the Aboriginal Areas Protection Authority (AAPA) and covered the area comprising the Bruce, Box Hole and Edwards Creek tenements.

The Arunta Project hosts a considerable suite of REE, gold and base metal targets which will be a key focus for near-term exploration.

Arunta Tenements

“Compelling targets”

MetalsGrove managing director Sean Sivasamy said: “We would like to thank the Traditional Owners of this land for their efforts in completing this important heritage survey.

“We are pleased that the outcomes from the survey allow MetalsGrove to undertake our planned exploration programs across some advanced and highly prospective REE, gold and base metals targets at Arunta.

“Our work to date has already identified some compelling targets, with surface field mapping and rock chip sampling within the Bruce Prospect area highlighting multiple zones of mineralised pegmatites.

“We look forward to reporting further updates on activity in the near term.”

Broad conductor

In July 2022, MetalsGrove identified a broad conductor at Bruce Prospect along strike from the Plenty River mine, which is adjacent to magnetic features interpreted to be components of the pegmatite intrusion.

Consequently, a program of about 3,000 metres of RC drilling is proposed to test the bedrock conductor at Whistleduck, Plenty River and Whitehorse historical pegmatite mines in three different stages, all within the Bruce Prospect area.

At Box Hole and Edwards Creek another 3,000 meters of RC drilling is proposed to test known exploration drilling targets.

Turning battery metals into bigger money-makers: MetalsGrove Mining

A long career in the mining industry prepared Sean Sivasamy well as he looks to turn lithium and the like into the world’s most valuable minerals.

“About 10 to 15 years ago, nobody talked about lithium,” says Sean Sivasamy, the managing director of MetalsGrove Mining Ltd (ASX:MGA).

He’s not wrong: in 2014, the average lithium carbonate price, measured in US dollars per metric tonne (mt), was $6,690.

Fast forward to last year, and it was nearly triple that, at US$17,000/mt.

“I’ll tell you a nice story, about why I have become attracted to the new energy movement,” Sivasamy begins.

“In 2016, Global Advanced Metals owned the Wodgina Lithium Project. And for some reason, they wanted to sell all their assets in Australia.

“You won’t believe it, but they sold it for A$16 million. That same asset today is worth a couple of billions.”

Mineral Resources Ltd was the buyer, and in 2019 it completed a joint venture agreement with US-based battery metals giant Albemarle.

Albemarle is the world’s biggest lithium producer. Listed on the New York Stock Exchange, it is currently worth about $31 billion, and according to recent reports, is considering spinning out its lithium assets, which could be worth north of $10 billion.

MetalsGrove to the future

It’s no wonder Sivasamy is interested — not to mention confident — that MetalsGrove will evolve to be a key player in the battery metals sector.

“I was originally more focused on copper and gold,” he says. “But I could see through some of these deals that lithium and battery metals were the future.”

Sivasamy joined MetalsGrove as managing director in September last year and the company listed on the ASX in early July following an initial public offering that raised $6.4 million.

“We’re focused on the exploration and development of its portfolio of high-quality lithium, rare earth, copper-gold, manganese and base metal projects in Western Australia and the Northern Territory,” Sivasamy says.

“We’re committed to green metal exploration and development to meet the growing demand from the battery storage and renewable energy markets in the transition to a decarbonised world.”

From India to Victoria to Western Australia and the Northern Territory

Sivasamy holds a Masters in Geology from the University of Madras and moved to Australia in 2000, combining further university studies with work in the goldfields in Victoria’s southeast.

Successful stints with a number of small Victorian mining companies followed before Sivasamy moved to Western Australia in 2011 and began working with Aditya Birla Group, one of India’s largest companies with a market capitalisation in excess of $50 billion.

“I took on a role as a senior geologist with Aditya Birla and was then promoted to geology manager, looking after all of their exploration assets,” he says.

Birla once managed two operations in Australia: Nifty and Mt Gordan (now known as the Capricorn Copper mine). Nifty is now in the hands of Cyprium Metals whiile Capricorn Copper is operated by 29Metals Ltd.

“In 2011, Capricorn Copper only had about a year of mine life ahead of it. The project hosted around 22 million tonnes of resource, and the board was looking at offloading it, considering that it had not been a very attractive investment,” Sivasamy says.

“I proposed that if we invested in the project, we could add additional resources and make it more attractive to their investors.”

“We turned those 22 million tonnes into about 182 million tonnes within three to four years. 29Metals raised $1 billion earlier this year and the mine life was extended well beyond a decade.”

Following that stint, Sivasamy also worked at OreMin Global, Pilgangoora Minerals and most recently Tambourah Metals, but says it’s the potential of MetalsGrove’s WA and Northern Territory projects that excites him most.

“We are very pleased with the progress made during the September quarter, highlighted by the confirmation of significant lithium pegmatite potential at our flagship Upper Coondina Project in WA,” he says.

MetalsGrove in a nutshell

MetalsGrove has five main projects: three in the Northern Territory (Bruce, Box Hole and Edwards Creek) and two in Western Australia (Woodie Woodie North and Upper Coondina).

The Bruce Prospect is prospective for rare earth and copper-gold mineralisation and the company kicked off surface mapping and a geophysical survey last month.

That exercise, along with rock chip sampling, has highlighted multiple zones of mineralised pegmatites, strengthening the company’s hopes as it prepares to kick off a maiden drill campaign in late November 2022.

“We are delighted with the initial outcomes from this surface mapping, which further confirms the strong mineralised potential of this region,” Sivasamy says.

“This work will help refine priority drill targets for testing in our upcoming drill program, scheduled to get underway in 2022’s final quarter.

Bruce is found within the wider Arunta minefields, near Alice Springs, which Sivasamy says hosts a “suite of exciting critical metals prospects”.

“We’re systematically working through each prospect to prioritise the most compelling targets for initial drill testing,” he explains.

Across the way, MetalsGrove’s Box Hole is prospective for base metal and rare earth mineralisation while Edwards Creek encompasses the Edwards Creek copper-zinc-lead and Mueller Creek copper-gold prospects.

Investors also see the potential beneath the ground: back in September, MetalsGrove shares doubled in a day, reaching a new benchmark of around 20 cents following news the company had identified lithium pegmatite potential at Upper Coondina.

Detailed surface mapping highlighted multiple, outcropping pegmatite dykes on the property, occurring in swarms within a regional corridor extending 8 kilometres.

“Given this project has never been systematically explored for lithium, we continue to be highly encouraged by these early works,” Sivasamy says.

While it’s still early days for MetalsGrove, Sivasamy remains excited about what’s to come.

“Our team has completed a tremendous amount of pre-drilling exploration work since we listed in July, and we are now ready to commence the next phase of our exploration campaign,” he explains.

“We enter Q4 with significant momentum and a busy exploration pipeline planned for the remainder of the calendar year.”

Pre-Drilling Surface Field Mapping at Bruce Rare Earth Prospect

Highlights

  • Pre-drilling detailed surface mapping is underway at the Bruce Rare Earth Prospect
  • ~6,000-line kilometre airborne magnetic and radiometric survey completed with data interpretation currently underway
  • Broad conductor confirmed along strike from the Plenty River mine which is adjacent to magnetic features interpreted to be components of the pegmatite intrusion
  • Mine Management Plan (MMP) approved for Box Hole and Edwards Creek Prospects – MMP is in progress for Bruce Prospect
  • Heritage survey approval is in progress for Arunta projects
  • Drilling is planned for Q4 2022 following completion of the heritage survey and surface field mapping works

Critical metals exploration and development company MetalsGrove Mining Limited (ASX: MGA), (“MetalsGrove” “MGA” or the “Company”), is pleased to announce that a pre-drilling detailed surface mapping program is underway at the Company’s Bruce Rare Earth Prospect in the Northern Territory.

As previously reported (see ASX release dated 20 July 2022), MetalsGrove has identified a broad conductor along strike from the Plenty River mine which is adjacent to magnetic features interpreted to be components of the pegmatite intrusion. The broad conductor has not been tested to date.

Surface field mapping and sampling is underway to identify and refine additional drill targets for testing during the planned drilling program scheduled to commence after completion of the current surface field mapping. This drilling program will be designed to test the bedrock conductor and historical pegmatite mines in Q4.

Commenting on the surface mapping at Bruce, MetalsGrove’s Managing Director, Sean Sivasamy said:

“Following the completion of the successful field mapping program in WA at our Upper Coondina Lithium Project, we are pleased to have our technical team completing the same exercise on the ground at Bruce. This program will play an important role in confirming the priority drill targets for our maiden drilling program at Bruce scheduled for later this year.

The Arunta Project hosts a suite of exciting critical metals prospects, and our team is systematically working through each prospect to prioritise the most compelling targets for initial drill testing. I look forward to providing further updates on our progress.”

Bruce Rare Earth Prospect Summary

The Bruce Rare Earth prospect is located within the Central Desert Region of the Northern Territory and covers an area of approximately 17,722 ha.

Significant rare earth occurrences have been found in the Harts Range and Plenty River mica fields within the Irindina Province. Joklik (1955), and Daly and Dyson (1956), provided details of the mica mines and documented numerous minerals associated with the host pegmatites. MetalsGrove is currently exploring pegmatite, breccia, vein and alteration-hosted rare earth mineralisation at Bruce.

Northern Territory Geological Survey (NTGS) completed the geological study in the Arunta and identified numerous pegmatites hosting rare earth occurrences including the Plenty River mica mine area. Figure-1 shows NTGS survey mapping and location of mineral occurrences (Geological Survey Record 2003-004, Rare Earth Element (REE) mineralisation in the eastern Arunta Region – KJ Hussey).

Airborne surveys underway at MetalsGrove’s NT Arunta project; maiden drilling in Q4

KEY POINTS

  • Airborne magnetic, radiometric survey to kick off at company’s only NT asset
  • 6,000 line program to provide data on the Bruce, Box Hole and Edwards Creek prospects
  • Bruce Prospect of foremost interest; prospective for lithium, rare earths, and gold

Not long after MetalsGrove (ASX:MGA) identified a massive electromagnetic target underground at its Arunta Project, the company is now chartering helicopters to run a 6,000m airborne magnetic survey overheard. 

The main target is the Bruce Prospect, which is up first on the company’s radar for drilling upon the conclusion of the surveys commenced today. 

The Bruce Prospect is believed to contain commercial quantities of lithium, rare earths, and gold. It is located in the Central Desert Region and covers over 17,000 hectares. The nearest historical mine is the Harts Range garnet mine some 80km southwest.

Q4 Maiden drilling on the horizon

The company notes aggressive drilling at a target identified last month underneath the Bruce prospect area of interest will commence upon conclusion of the airborne survey. 

That magnetic target is believed to be related to lithium pegmatites. 

The breakdown of coverage over each of the targets makes clear where MetalsGrove’s priority lies. 

Three targets at the Arunta Project will be subject to this round of airborne surveys:

  • Bruce Prospect (3,954 line-kilometres) 
  • Box Hole Prospect (1,147 line-kilometres) 
  • Edwards Creek Prospect (872 line-kilometres) 

Drilling will take place in the fourth quarter of 2022. 

“Targeted yet aggressive:” Management 

“This survey programme will play an important role towards refining our priority drill targets for our maiden drilling programme,” MetalsGrove MD Sean Sivasamy said.

“Our team has already completed significant work highlighting strong potential at Bruce.” 

MetalsGrove is having a busy month so far, with the company flying an airborne survey over its WA Woodie Woodie acreage at the start of August. That project is prospective for manganese, another battery metal alongside lithium. 

Isn’t MetalsGrove a lithium explorer? 

Yes, it is. But the same reasons driving enthusiasm for copper, nickel, and silver, are also playing out in manganese exploration markets. 

Last year, Livewire Markets went so far as to describe manganese as the ‘next hot battery metal.’ 

Manganese is also a valuable alloy for steelmakers. While pricing for the metal is somewhat opaque, Chinese metal market information provider SMM notes prices at many benchmarks sit above US$2,000 a tonne. 

This reflects a tenfold increase for prices since 2014, when a commodities glut caused many operations to be mothballed. 

And lithium prices, of course, remain some 350% higher than this time last year. 

Existing survey data interpreted into a visual image from existing magnetic information at Arunta. The red like that extends beneath the  historical Plenty River mine is what MGA has its eye on; the target is believed to be lithium pegmatite.
