MetalsGrove Mining Ltd (ASX:MGA) has soared on confirming high-grade rare earth element (REE) carbonatite mineralisation up to 7,000 parts per million (ppm) total rare earth oxide (TREO) during reverse circulation (RC) drilling at the Arunta Project’s Bruce Prospect in the Northern Territory.

Importantly for any future development scenario, the most significant intersections are near the surface.

Investors have responded strongly at the market open, sending MGA shares 63.7% higher to $0.18.

The critical metals exploration and development company last month completed 16 reverse circulation (RC) holes for 2,343 metres designed to test high concentrations of valuable magnetic and heavy rare earth elements from soil sampling.

What the results show

Drilling has confirmed that the carbonatite outcrops extend east-west over 9 kilometres and remain open.

Standout results from the RC drilling include:

Plenty River

• BRR23016 – 2 metres at 4,000 ppm (0.4%) total rare earth oxide (TREO) and 35% magnetic rare earth oxide/rare earth oxide (MREO/REO), 27% neodymium and praseodymium (NdPr/TREO) from 21 metres, including 7,000 ppm (0.7%) TREO, 35% MREO/TREO, 28% NdPr/TREO from 21 metres; and
• BRR23009 – 3 metres at 1,010 ppm TREO and 28% MREO/TREO, 41% HREO/TREO and 17% yttrium oxide (Y₂O₃/TREO) from 10 metres, including 2 metres at 1,300 ppm TREO and 29% MREO/TREO, 19% NdPr/TREO and 23% Y₂O₃/TREO from 10 metres.

Plenty River East

• BRR23003 – 33 metres at 13% magnesium oxide (MgO) from 39 metres and 3 metres at 535 ppm vanadium oxide (V₂O₅) from 45 metres;
• BRR23002 – 26 metres at 17% MgO from 30 metres; and
• BRR23001 – 4 metres at 2.6% titanium dioxide (TiO₂) from 63 metres.

Bruce

• BRR23013 – 1 metre at 7,785 ppm copper oxide (CuO) (0.8% CuO) from 103 metres, 3 metres at 1,000 ppm lead oxide (PbO₂) from 63 metres, 2 metres at 1,170 ppm PbO₂ from 84 metres and 3 metres at 1,245 ppm zinc oxide (ZnO) from 63 metres, 2 metres at 1,710 ppm ZnO from 83 metres; and
• BRR230014 – 6 metres at 1.7% TiO₂ from 102 metres.

“Clear potential”

The explorer believes that the grades returned in the Bruce drilling favour the project if sufficient tonnes can be found.

“We are delighted with the initial outcomes from our first drilling campaign at Bruce,” MetalsGrove managing director Sean Sivasamy said.

“These results demonstrate the clear potential for Bruce to host a considerable carbonatite and REE system with the outcropping strike of now extending over 9 kilometres.

“The Bruce Prospect is shaping as an excellent opportunity for MGA and demonstrates the underlying exploration potential of our Arunta Project area in the Northern Territory – a region home to several world-class deposits.”

Critical metals exploration and development company MetalsGrove Mining Ltd (ASX:MGA) has wrapped up its first reverse circulation (RC) drilling program at the Bruce Rare Earth Element (REE) Prospect, Northern Territory.

The Bruce prospect is part of the company’s Arunta Project, north of Alice Springs in the Central Desert Region of the Northern Territory and covers an area of around 17,722 hectares.

Program on time and on budget

The maiden 2,343-metre program was completed on time and within budget. A total of 16 RC holes were drilled to test several high-priority targets including identified multiple carbonatite and REE-bearing drill targets recently reported from soil sampling.

A recent aeromagnetic and surface geochemistry program also defined a 1,000-metre by 600-metre intrusive system considered highly prospective for REE mineralisation at the prospect.

Initial observations indicate that the carbonatite system is continuous, with a similar weathering profile to that intersected in the mineralised discovery holes.

Last year MGA reported that it had 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.

Strike includes multiple mineralised areas

The company is confident that strike extends over 9 kilometres, with multiple parallel mineralised areas and a high percentage of valuable magnetic and heavy rare earth elements.

Significant rare earth occurrences have been found in the Harts Range and Plenty River mica fields within the Irindina Province and MGA is exploring pegmatite, breccia, vein and alteration-hosted rare earth mineralisation at Bruce.

A Northern Territory Geological Survey (NTGS) in the early 2000s identified numerous pegmatites hosting rare earth occurrences in the Arunta region, including the Plenty River mica mine area.

MGA’s soil sampling confirmed the following:

• up to 1,800 parts per million (ppm) total rare earth oxide (TREO);
• 38% heavy rare earth oxide (HREO)/TREO;
• 31% magnet rare earth oxide (MREO)/TREO;
• 23% neodymium-praseodymium (NdPr)/TREO; and
• 23% Yttrium Oxide (Y2O3)/TREO.

First results from this maiden drilling program are expected to be reported to the market within 4-6 weeks.

MetalsGrove Mining Ltd (ASX:MGA) has set the drill bit spinning as part of a maiden 2,000-metre campaign to test rare earth targets over the Arunta Project’s Bruce prospect in the Northern Territory.

The Aussie explorer is taking the magnifying glass to Bruce’s highest priority carbonatite and rare earth element (REE) targets as it seeks to expand its understanding of the prospect’s critical minerals upside.

Following the three-week drilling campaign, first assays are expected within four to six weeks, meaning it won’t be long before the company has more news for the Australian sharemarket.

Soil sampling paves the way

MetalsGrove’s maiden program comes soon after it mapped carbonatite and high-grade REEs over more than 9 kilometres at Bruce, where recent soil sampling confirmed high concentrations of valuable magnetic and heavy rare earth elements (31% and 38%, respectively).

Led by encouraging soil results that revealed up to 1,800 parts per million total rare earth oxides (TREO), MGA has crafted an exploration compass to guide its targeted drilling program.

On top of the newly minted targets, a recent aeromagnetic and surface geochemistry program has defined a 1,000-metre by 600-metre intrusive system — considered highly prospective for REE bounty.

A closer look at Bruce

The Bruce rare earths prospect covers nearly 18,000 hectares in the NT’s Central Desert Region, an area renowned for cattle rearing and gold mining.

Among other priority targets in the region, MGA is particularly excited by a broad conductor along strike from the Plenty River mine, where significant rare earth finds were made in the 1950s.

The Northern Territory Geological Survey has completed geological studies in the Arunta region and identified numerous pegmatites hosting rare earth occurrences, including the Plenty River mica mine area.

As such, MetalsGrove is currently exploring pegmatite, breccia, vein and alteration-hosted rare earth mineralisation at Bruce, and the upcoming drill program will provide detailed insight on the prospectivity of these structures.

“The Arunta region is a world-class mineralised province and MGA has a clear strategy in place to systematically unlock the true underlying potential of its strategic footprint in the area,” managing director Sean Sivasamy said in early May.

“I look forward to providing the market with regular updates on our progress.”

Next up

Beyond the Bruce-centred drilling campaign, MetalsGrove plans to interpret more geophysical data to the Arunta Project’s east and west.

Depending on what it proves up, the explorer will chase results with more follow-up drilling and geochemical analysis.

MetalsGrove Mining Ltd (ASX:MGA) MD Sean Sivasamy speaks with Proactive soon after the company announced it has identified high-value magnetic and heavy rare earth elements (REE) at Bruce prospect within the Arunta Project in the Northern Territory. Outcropping carbonatite and high-grade REE mineralisation now extends over 9 kilometres of strike. MGA will now begin a maiden drilling program at Bruce – possibly as soon as next week.

MetalsGrove Mining Ltd (ASX:MGA) has added just under A$70,000 to the company coffers to boost rare earths exploration thanks to a Northern Territory Government grant.

The cash injection will support work at the Arunta Project’s Bruce prospect, where an imminent 2,000-metre drilling campaign will test the property’s best-looking targets, including a broad conductor and a substantial intrusive system measuring 1,600 metres by 600 metres.

MetalsGrove managing director Sean Sivasamy said his team was “delighted” to receive the funding and thanked the NT Government for the exploration grant.

“The Arunta region is a world-class mineralised province and we have put in place a clear strategy to fast-track our exploration in the region and unlock value for MGA shareholders,” he stated.

“I look forward to providing the market with regular updates on our progress.”

Resourcing the Territory

MetalsGrove’s A$69,393.40 grant was administered by the Northern Territory Geological Survey (NTGS) as part of the Geophysics and Drilling Collaborations program.

Ultimately, this campaign is just one facet of the larger Resourcing the Territory initiative, which provides all-important capital to stimulate exploration and mineral discovery in the region.

The A$9.5 million funding pool represents the largest and longest-term investment ever made by a NT government to support resources exploration and development, including:

• Near-term resource development through an increased focus on exploration of ‘brownfields’ sites;
• identification and promotion of new areas of the Territory for resource exploration;
• acceleration of geoscience programs to attract and de-risk mineral exploration; and
• studies on the territory’s geological potential for critical commodities to support a low-emissions future.

Building on Bruce

Located just north of Alice Springs, MGA’s Bruce prospect is at the epicentre of its flagship Arunta camp.

The rare earths target covers roughly 17,722 hectares in the NT’s Central Desert region, where material rare earth discoveries have been staked in the Harts Range and Plenty River mica fields within the Irindina Province.

Interestingly, the NTGS has completed a geological study within the Arunta region and identified numerous pegmatites hosting rare earth occurrences, including the Plenty River mica mine area.

Nearly a year ago, MetalsGrove uncovered a broad conductor near the Plenty River mine, making its discovery next to magnetic features that are likely part of a pegmatite intrusion.

Moreover, previous work at the Arunta project has confirmed that rare earth anomalism is tied to copper, gold and base metal anomalism, putting more minerals on the radar.

This prospectivity ties into MGA’s broader mission: to farm up green metals and meet the growing demand from the battery storage and renewable energy markets in the transition to a de-carbonised world.
