Aruma Resources plans to follow up on ‘bonanza’ gold results at Salmon Gums Project, WA

Aruma Resources (ASX:AAJ) is gearing up to conduct a targeted diamond drilling program at its Salmon Gums Project in Western Australia. 

The company says in its latest quarterly report the drilling is planned to follow up on previous ‘bonanza’ gold results from drillhole SGRC039, which returned 5m @ 50.2g/t au. 

The program is also designed to test the structure of the ‘very high-grade’ gold mineralisation around this intersection with the view to refine Aruma’s geological and structural model for the Salmon Gums Project and support the definition of targets for further drilling to extend this gold zone. 

Aruma notes that its recently completed auger sampling program conducted at the project uncovered the potential for new gold prospects, with multiple rare earth element (REE) soil anomalies also detected. 

Meanwhile, at the Carter Well Gold Project, Aruma has planned an initial field sampling program as the first-pass exploration for the project. The company notes no on-ground exploration was conducted at the project during this past quarter. 

During this past quarter, Aruma completed a placement to raise $2.3 million to help fund ongoing fieldwork programs. 

Aruma closed out the June quarter with $3.23 million cash at hand, according to the quarterly report. 

The Salmon Gums Project is located 300km south of Kalgoorlie in Western Australia and covers a total area of about 360km-square.

Aruma Resources strikes collection of ‘significant’ REEs and base metals at Saltwater Project, WA

Minerals explorer Aruma Resources (ASX:AAJ) has unearthed ‘significant’ rare earth elements (REEs) and cobalt following initial reconnaissance fieldwork at its Saltwater Project in Western Australia. 

The company says results are ‘highly encouraging’ and have been generated from its first phase of surface sampling at the project. These results are interpreted to share similarities to those seen at Dreadnought Resources’ (ASX:DRE) neighbouring Bresnahan REE Project. 

Results also demonstrate the presence of anomalous lead-zinc in conjunction with the already identified commodities, reaffirming the project’s potential to host unconformity heavy rare earth elements (HREEs) and base metal deposits. 

Aruma reports these results, paired with elevations of phosphorus, strontium, and thorium, as well as with the presence of ‘significant’ barium and manganese, offer initial encouragement for the potential of Saltwater to host a VMS or MVT-style mineralisation system.  

As a result, mapping and infill surface sampling at priority areas is expected to begin this month to develop drill targets in conjunction with ongoing systematic sampling. 

Current sampling is targeting the interpreted 80km strike of favourable stratigraphy at Saltwater and is working to define additional areas of interest. 

Key results include hole AR12232 with 1158 parts per million (ppm) total rare earth oxide (TREO); 25% neodymium-praseodymium (NdPr)/TREO and 21% heavy rare earth oxide (HREO)/TREO; and hole AR12291 with 1022ppm TREO; 25% NdPr/TREO and 27% HREO/TREO.  

Commenting on the results, Aruma Resources Managing Director Glenn Grayson says: “We are delighted with the initial results from our first phase of REE-focused field work at Saltwater. The sampling program represents our first stage of on-ground REE work at the project, and the results have exceeded expectations, reaffirming our view of Saltwater’s potential for hosting unconformity HREEs. 

We are delighted with the initial results from our first phase of REE-focused field work at Saltwater”

These initial results constitute a resounding success for our exploration approach thus far. Furthermore, the grades of the surface samples for base metals are exciting and provide an additional exploration focus at the Saltwater Project. This potential will be further investigated in the company’s ongoing fieldwork at Saltwater.” 

Aruma Resources is an ASX-listed mineral explorer focused on the exploration and development of a portfolio of prospective gold and lithium projects strategically located in major active mineralised belts in Western Australia.

The company’s Saltwater Project is located in the Pilbara region of Western Australia and was originally pegged by Aruma in 2020 for its gold prospectivity but is also considered prospective for REE mineralisation. 

Aruma Resources had $2.46 million cash at hand and no debt as of 31 March 2023, as stated in its latest quarterly report.

Aruma Resources taps investors for $2.25 million to accelerate fieldwork at projects in WA

Australian explorer Aruma Resources (ASX:AAJ) has received firm commitments to raise $2.25 million in a placement to accelerate fieldwork across its multi-element project portfolio in Western Australia.

The company reports the placement will fund a mapping and sampling program at the Saltwater Rare Earth Elements (REE) Project, as well as the next phase of drilling and metallurgical testwork at the Mt Deans Lithium Project and further drilling at the Salmon Gums Gold Project.

At Saltwater, the company plans to complete systematic mapping and sampling across an interpreted 80km strike. This program is designed to provide targets for a maiden drilling program.

Aruma reports it has identified up to 15m-thick pegmatites at Mt Deans, and drilling campaigns have confirmed the presence of lithium-rich pegmatites. Additionally, recently completed first-phase metallurgy has confirmed the ability to produce a lithium concentrate, while further drilling and metallurgy are planned as the next steps in the company’s systematic exploration and appraisal of the project.

The company reports Salmon Gums is situated 30km along strike and in the same stratigraphy as Pantoro’s (ASX:PNR) ‘high-grade’ Scotia Gold Project. Aruma says it has conducted multiple drilling programs at the project that have returned ‘bonanza’ gold grades, and further targeted drilling is planned to extend the ‘high-grade’ mineralised zone.

The placement was ‘strongly bid’, which the company says is a testament to its focus on core REE, lithium, and gold projects in Western Australia. This placement also saw several investors join Aruma’s share registry for the first time.

Aruma reports that once the placement is complete, it will have a ‘strong’ balance sheet, with a cash balance of about $3.7 million to undertake its work programs.

Under the placement, Aruma will issue more than 38.79 million shares at $0.058 per share. This represents a 16.2% discount to the company’s 10-day volume weighted average price (VWAP) up to the date of the placement announcement.

The company also advises that Chairman James Moses and Director Peter Schwann participated in the placement and have subscribed for a total of over 1.439 million shares, subject to shareholder approval.

The offer also includes a free attaching option for every share subscribed for in the placement, exercisable at $0.10 up to 11 June 2026. Aruma notes the options and director shares remain subject to ASX listing requirements and shareholder approval.

GBA Capital acted as lead manager to the placement and will be paid a 6% commission on funds. Subject to shareholder approval, GBA will receive 15 million options exercisable on the same terms as the placement. Aruma reports it will convene a shareholder meeting in the coming weeks to seek shareholder approval.

New shares under the placement are expected to be issued on 13 June 2023. This does not include the shares subscribed for by the company’s directors.

Aruma Resources first off the line with start of field program in emerging REE province, WA

Aruma Resources (#ASX:AAJ) has begun a rare earth element (REE) fieldwork program at its Saltwater Project to position itself with a first-mover advantage in an emerging REE province in Western Australia. 

The company says fieldwork will consist of mapping and ‘extensive’ surface geochemical sampling over an 80km strike length of prospective stratigraphy for light and heavy REE. This work is supported by a mapped outcrop identified from a reconnaissance site visit by Aruma. 

Aruma reports sampling will begin at a ‘high priority’ radiometric target with a strike length of up to 15km, located west of the Nobby’s prospect. Selected samples from this initial phase of sampling will be sent for laboratory analysis. 

This round of sampling is hoped to warrant the start of a maiden REE-focused drilling program, subject to results, and is expected to progressively test the interpreted 80km strike.  

The company notes it will also adopt a multi-commodity approach to its fieldwork at Saltwater and will assess the base and precious metals prospectivity in parallel with its REE focus.

Assay results from the surface sampling program are expected to be received in July and will be released to the market as they become available.  

Speaking on the start of fieldwork, Aruma Resources Managing Director Glenn Grayson says: “We are excited by the REE potential of the Saltwater Project, which we are of the view represents a significant underexplored REE opportunity in what is as an emerging REE province. 

We are excited by the REE potential of the Saltwater Project, which we are of the view represents a significant underexplored REE opportunity in what is as an emerging REE province.”

We have defined an extensive interpreted strike of 80km, which will be systematically explored for its REE potential, and we believe that our ground holding is amongst the most prospective REE tenure in the region. 

Given the burgeoning demand for critical rare earth elements, our fieldwork is designed to aggressively and systematically unlock the REE potential of the project.” 

The company notes this program is being undertaken following the extension of the gold-mineralised footprint at its Salmon Gums Gold Project, also in Western Australia, as announced by Aruma last week (26 May 2023).

Aruma stated drilling encountered the newly defined ‘Rose’ prospect and succeeded in extending gold mineralisation at the priority Iris and Thistle prospects. 

Aruma Resources is an ASX-listed minerals exploration company focused on the exploration and development of its portfolio of prospective gold and lithium projects strategically located in major, active Australian gold mineralised belts in Western Australia. 

The company’s Saltwater Project is located within the Pilbara region of Western Australia and was originally pegged by Aruma in 2020 for its gold prospectivity. Exploration to date has included 2 phases of reverse circulation (RC) drilling within a targeted area of the project. 

The project is also situated adjacent to Dreadnought Resources’ (ASX:DRE) Bresnahan REE Project, which has returned ‘significant’ initial heavy REE results.

Aruma Resources cultivates extended gold footprint at Salmon Gums Project, WA 

Aruma Resources (ASX:AAJ) has extended the gold mineralised footprint at its Salmon Gums Gold Project in Western Australia following a recent reverse circulation (RC) and auger drilling program.

The results, generated from 44 RC holes and 894 shallow auger holes, provide further support to the potential the project has as an emerging new gold camp. 

Results are also indicative of the existence of multiple zones of gold that expand the gold-mineralised footprint at the priority Iris and Thistle prospects.

Aruma reports drilling has also identified a new target, named the Rose prospect, between the Iris and Thistle prospects, with multiple new gold intersections returned from this new target. 

Key results include hole SG23RC030 with 1m @ 3g/t Au from 71m; hole SG23RC037 with 1m @ 1.3g/t Au from 46m and 5m @ 0.4g/t Au from 103m; hole SGRC066 with 1m @ 4.1g/t Au; and hole SG23RC026 with 1m @ 2.3g/t Au from 27m. 

The RC drilling was designed to follow up on ‘bonanza-grade’ gold intersected by Aruma in previous drilling, which returned gold grades up to 224g/t Au, while auger drilling was undertaken to test ‘strong’ coincident gold- and arsenic-in-soil anomalies within the wider project area.

This recent drilling has also warranted the drafting of plans for a diamond drilling program targeting further ‘bonanza’ gold intercepts of 5m @ 50.2g/t Au in order to better define controls and extensions to this very ‘high-grade’ gold zone.     

Speaking on the results, Aruma Resources Managing Director Glenn Grayson says: “The Salmon Gums Gold Project has the potential to host a significant mineral deposit. This round of drilling was designed to test our geological model for gold mineralisation at the project over a considerable strike and has been successful in intersecting multiple zones of gold mineralisation, which has resulted in the definition of a new target at the Rose prospect.

“The Salmon Gums Gold Project has the potential to host a significant mineral deposit”

As our understanding of the gold model at Salmon Gums increases, as a next step, we plan to undertake targeted diamond drilling in several orientations to follow up the bonanza gold intersection of 5m at 50.2g/t from our previous phase of drilling and to increase our understanding of what is controlling the high-grade gold.”  

Additionally, auger drilling is noted to have identified potential for multiple new gold prospects and has also returned multiple rare earth element (REE) soil anomalies. Follow-up analyses are currently being completed to provide a more comprehensive REE value to these anomalies. 

Aruma Resources is an ASX-listed minerals exploration company focused on the exploration and development of its portfolio of prospective gold and lithium projects strategically located in major, active Australian gold mineralised belts in Western Australia. 

The company’s Salmon Gums Project is located about 200km south of the major regional centre of Kalgoorlie and about 60km south of the mining town of Norseman in WA. It comprises 2 exploration licences with 1 exploration licence application that cover a total land area of 360km-square.

Aruma Resources begins third floatation test at Mt Deans Lithium Project in WA

ASX-listed minerals exploration company Aruma Resources (ASX:AAJ) is conducting a third floatation test as part of ongoing metallurgical testwork at the Mt Deans Lithium Project in Western Australia.

The company reports the floatation test and subsequent gravity separation test is utilising samples that have not been reverse circulation (RC) drilled.

Aruma says pegmatite samples from outcrop at the project has been collected for this purpose and notes the next phase of testwork will begin immediately.

This testwork follows initial sighter testwork that aimed to establish what kind of products could be produced from pegmatites at the project, and provide a first step in a pathway to potential project development.

Aruma says 2 floatation tests were conducted, with initial results confirming a lithium concentrate can be produced with a concentrate grade of 3.1 times Li2O feed grade returned from the floatation tests. The company reports it achieved recoveries of 80% into 25% of the mass.

Additionally, Aruma reports the initial float result also delivered ‘promising’ upgrades relative to original feed grade for other metals including potassium, rubidium, caesium, tin, and tantalum. The program also highlighted the value of the tin and tantalum at Mt Deans, with both being able to be separated in the floatation process.

Aruma also reports the initial results have been delivered from testwork on pulverised RC drill chips, which the company acknowledges as being ‘sub-optimal’ for floatation testwork. The company anticipates that testwork using a crushed rock feed will deliver a ‘higher’ grade concentrate, and ‘higher’ recoveries.

“These sighter testwork results give us a great deal of confidence in the potential value we see at Mt Deans”

Commenting on the results, Aruma Resources Managing Director Glenn Grayson says: “These sighter testwork results give us a great deal of confidence in the potential value we see at Mt Deans. To deliver a first pass concentrate of 2.64% Li2O with another 0.6% Li2O in the slimes, provides us with confidence that floatation works and that Mt Deans could deliver a typical lepidolite concentrate of around 4% Li2O.

The upgrade of all metals from this early-stage testing shows us that further work to establish what may be achieved with the Mt Deans pegmatite is key to realising the project’s full potential.

Mt Deans was historically a tin mine in the 1940s, and a tantalum project 15 years ago. This, in conjunction with the potential lithium value, plus rubidium and caesium, makes Mt Deans a ‘high’ potential project for Aruma.”

Aruma reports the initial float test results achieved ‘high’ recoveries with 80% recovered in the first 2 concentrates. The second floatation test managed to increase the Li2O grades by an average of 3.1 times to a grade of up to 2.64% Li2O. Using a higher-grade sample of 1.2% Li2O may produce a flotation concentrate above 3.5%.

The company notes that rubidium grades are ‘high’ in concentrate, at close to 2% Rb2O. Potassium has been concentrated to 5.88%, which is almost a 3 times increase in grade.

Additionally, Aruma notes the de-slime contained lithium with a grade of 0.63% Li2O. Initial assumptions for this include RC drilling generated fines which reported to the de-slime overflow, and the fluids used by the drillers have affected how the micas have reacted to the reagents in the floatation.

Aruma Resources is an ASX-listed minerals exploration company developing a portfolio of prospective gold and lithium projects in Western Australia. The company’s projects include the Carter Well, Melrose, Saltwater, and Salmon Gums Gold projects, as well as the Mt Deans Lithium Project.

Mt Deans covers 1.44km-square in the Eastern Goldfields Terrane of the Yilgarn Craton. The project is located about 10km south of the mining town of Norseman, and it is considered prospective for lithium, tantalum, and rare earth elements.

Aruma Resources: renewed focus with the blinkers off amid changing of the guard

This article is a sponsored feature from Mining.com.au partner Aruma Resources Ltd. It is not financial advice. Talk to a registered financial expert before making investment decisions.

A growing global population and ever-expanding technological development have considerably increased demand for various critical minerals to the point it’s altered the direction of the mining industry and explorers alike.

Until recently, critical minerals and rare earth elements (REEs) in particular were relatively unknown outside of those who occupied a niche métier within mining’s many echelons.

Yet such is the importance and need of these raw materials, exploration companies with exposure to them tend to embrace the mining and value proposition with vigour. Even if their initial minerals focus was elsewhere.

While Aruma Resources (ASX:AAJ) has predominantly been exploring for gold, in February the company unveiled it had uncovered REEs at its 100% owned Saltwater Gold Project in the Pilbara region of Western Australia. 

Now with plans to pursue the rare earths potential at the Saltwater Project, newly appointed Managing Director Glenn Grayson has officially signalled a changing of the guard at the company.

He tells Mining.com.au Aruma is casting a wide net with an open-minded drive towards exploration.

“The blinkers are off with respect to what we are in search of. We will be targeting REEs at Saltwater, as well as gold and anything else that we identify. If we see something that will add value to our projects then we will follow that up.”

“The blinkers are off with respect to what we are in search of. We will be targeting REEs at Saltwater, as well as gold and anything else that we identify”

Rare earths in particular are found in applications in disparate fields, such as magnetic, metallurgical, nuclear, chemical, catalytic, electrical, and optical. They are essential in hybrid-car batteries, phosphorescent lamps, portable electronic devices, and wind turbines.

Under the common models in which REEs are generally found, those associated with sedimentary rocks can also be associated with gold and base metals, meaning uncovering REEs is not actually that rare. 

Aruma has identified an interpreted reactive lithology extending over a total linear target of in excess of 80km of prospective shales. The company is undertaking a targeted fieldwork program at Saltwater designed to position Aruma with a first-mover advantage in what is an emerging rare earths province.

The Saltwater Project consists of 4 granted exploration licences over 450km-square.

Changing of the guard

In January, Aruma appointed then Chief Operating Officer Grayson as MD who replaced the company’s founding MD Peter Schwann who led the company since its listing in 2010. Grayson has played a key role in advancing the company’s portfolio of prospective lithium and gold assets in Western Australia over his tenure at Aruma.

While his predecessor may have had a different approach to exploration, Grayson says his vision is to continue moving forward while assessing all of Aruma’s options with due diligence.

“I guess it’s a fresh set of eyes looking at things, as we change. It’s not the Aruma of old which previously operated with a different perspective and I’ve taken over the company and it’s a bit of a shake up in the way things are being done. We’re looking at the gold, but we’re also pushing the lithium and we’re looking for rare earths, and it’s just that we haven’t got blinkers on any one commodity.”

“I guess it’s a fresh set of eyes looking at things, as we change. It’s not the Aruma of old which previously operated with a different perspective…”

While the new MD says his approach is not aggressive, as an experienced exploration geologist, he does want Aruma to be proactive and open-minded about the opportunities that unfold before the company.

“I’ll cast my net a bit wider and try and understand what’s going on to look at what might be there. The way I’ll operate is to step back and have a big picture look and try and work out what might be going on first and then go in and test the ground for what we might have outside of the known gold.

I think the multi commodity approach is certainly healthy in the current climate. The commodities we’re looking for too, I think are all pretty desirable.”

Shareholders agree and have expressed support in the direction the company is taking by assessing the gold and rare earths in particular in a different light, says Grayson, who has in excess of 27 years’ experience as a geologist and strong depth of technical expertise in gold exploration and development in Western Australia and Victoria.

“We’ve been trying to explain to them (shareholders) what the potential might be and they’re all excited about it.”

Refreshing look at Saltwater

Under his guidance, Aruma has targeted available ground that fits its mineralisation model while specifically looking for prospective terrain that has for various reasons been previously overlooked.

The company’s Mt Deans assets is a tantalum-rich pegmatite outcrop, which had not previously been sampled for lithium. Carter Well is mapped as granite but has not previously been explored yet has a mafic greenstone outcrop.

At Saltwater, local indigenous people have successfully prospected for gold nuggets, however it is completely unexplored for precious metals and rare earths. Meanwhile, the company’s main focus is at Salmon Gums where the next phase of drilling is underway, following up on previous bonanza grade gold intersections.

The MD explains to this news service that of those assets, Saltwater Project offers a unique and refreshing opportunity for Aruma.

“It’s going to be a methodical process with Saltwater, it’s a big area and it’s very remote”

“It’s going to be a methodical process with Saltwater, it’s a big area and it’s very remote. It’s getting up there and passing a wide net, as we’ve got 80km of strike of the stratigraphy that we think has the most potential to host something.”

The MD says the company’s approach to Saltwater will be somewhat measured with several site visits expected to occur over the coming 3-4 months to take rock chip samples.

Aruma has already undertaken a more detailed site visit, where it conducted a surface sampling program. Samples will be sent for laboratory analysis, and subject to results it will then complete a geophysical survey and mapping program with a view to defining targets for a maiden REE-focused drill program.

Ideally, the project is also situated some 100km south-west of the regional mining centre of Newman. The project was originally pegged by Aruma in 2020 for its gold prospectivity, based on the reactive stratigraphy adjacent to the Nanjilgardy Fault within the project area that controls about 6 million ounces of known gold mineralisation along its entire strike. Aruma’s exploration at Saltwater to date has been gold-focused and has consisted of 2 phases of reverse circulation (RC) drilling within a targeted area.

Rare earths have common applications

The newly installed MD notes that the reason Aruma will take a measured and cautious approach to Saltwater is that it will need to investigate the complexities not only of the minerals, but the broad and disparate end users they will eventually attract. He says the importance and uses of REEs are not as well understood as many commodities such as gold and lithium applications and it is still early stages of Aruma’s understanding of what is in the ground.

“The historic results only list REEs and not the specific elements within the series. Our neighbours (Dreadnought Resources) are reporting heavy rare earth elements and specifically neodymium.”

Neodymium

Neodymium is a hard, slightly malleable, silvery metal that quickly tarnishes in air and moisture. When oxidised, it reacts quickly and is generally regarded as having one of the most complex spectra of the elements.

The metal has an unusually large specific heat capacity at liquid-helium temperatures, so is useful in cryocoolers and also has applications for glass and in lasers.

Neodymium magnets are the strongest permanent magnets known. A neodymium magnet of a few tens of grams can lift a thousand times its own weight and can snap together with enough force to break bones. While these magnets are superior, cheaper, lighter, and stronger than samarium–cobalt magnets, they do lose their magnetism at lower temperatures and tend to corrode, which samarium–cobalt magnets do not.

In H1 2022, there was market tightness for neodymium, which was accelerated by above-market Chinese demand investment in neodymium-iron-boron magnet capacity. However, in recent times China reaffirmed its dominance of the rare earths by significantly ramping up its mining and refining quotas. In 2021, China produced the most REEs at 168,000 metric tons, with the second largest producer being the US with just 43,000 metric tons.

In terms of potential types of end users for Aruma’s REEs products should it one day become a mine, Grayson says the situation is continually evolving, adding that such customers are needed to be developed as the critical minerals space develops.

Magnet for the market

Moving forward, the near-term growth objectives for Aruma are clear although the rare earths will be an attractive value and investment proposition for the market.

The MD says: “I still see potential in the Norseman Lithium Project. I think lepidolite will become every bit as important a source for lithium as spodumene currently is. The drilling currently being done at Salmon Gums is really important to us. If we can grow the footprint of the high-grade gold then that will be substantial. And getting up to Saltwater to do a major sampling campaign is exciting.”

“The drilling currently being done at Salmon Gums is really important to us”

Aruma already has some grab samples and historic data which has put the company on the front foot with Saltwater. An assessment of historic exploration within the project area has revealed REE, base metals, gold, and uranium results from previous explorers in the region. U308 Limited (U308) reported ‘extremely high’ assays results up to 11% rare earths at the Sirius and Lavanto prospects within the area in 2010, in grab samples.

Previous exploration by U308 also delivered grades of up to 3.1% Cu, 1.4% Pb, 1.5% V (vanadium), and 2g/t Au in samples from costeans at the Nobbys prospect. Aruma also plans to pursue the multi-commodity potential of the project area in its planned fieldworks programs. Other REE occurrences have been recorded at Saltwater in drillholes and surface samples. The status of the Saltwater area as an emerging REE province has been consolidated by Dreadnought Resources (ASX:DRE) and its recent pegging of a significant landholding at its Bresnahan Project, immediately adjacent to Saltwater.

Meanwhile, Aruma has begun the next phase of drilling at its Salmon Gums Gold Project, following up on previous bonanza grade gold intersections. This phase of drilling will consist of 47 reverse circulation (RC) holes for 5,500m, and a 1,026 sample shallow auger drilling program and is designed to follow-up previously recorded ‘high-grade’ intersections. It will also test ‘strong’ coincident gold and arsenic in soil anomalies to extend the current known gold mineralised areas at the Iris and Thistle prospects.

Grayson notes: “Hopefully we will identify more high-grade gold in the Thistle area and extend this. Additional drilling and gold results will help us understand the gold mineralisation further and allow us to immediately follow-up with more drilling.”

He adds that testing ‘strong’ coincident gold and arsenic in soil anomalies is important.

“The Norseman style of mineralisation is very coincident with arsenopyrite, so a strong arsenic and gold in soils anomaly is a very good start. Surface soil sampling of the wheatbelt is difficult to analyse in that the soil has been mechanically re-worked by farmers for decades. This is why we are doing some auger sampling. We believe that taking a sample greater than 1m depth will give us a much more reliable test of the areas for mineralisation.”

Aruma Resources works to branch out Salmon Gums Gold Project mineralised footprint

Aruma Resources (ASX:AAJ) expects to complete its reverse circulation (RC) and auger drilling programs this month at its Salmon Gums Gold Project in Western Australia.

The auger drilling program, which started in early April, will provide more effective testing for gold mineralisation (and other elements) at depth below that of a standard soil sampling program.

in addition to gold, the auger program will sample for a multi-element suite of 48 different elements

The company says in addition to gold, the auger program will sample for a multi-element suite of 48 different elements. It will also seek to extend the project’s mineralised footprint, particularly in the southern extent of the project.

Aruma Managing Director Glenn Grayson notes the 2023 drilling campaign will follow up previous ‘bonanza-grade’ gold intersections and seeks to extend the ‘high-grade’ mineralised area at the Iris and Thistle prospects.

Previous drilling at Salmon Gums intersected gold grades including 5m at 50.2g/t Au in drillhole SCRC39, with grades as high as 228g/t Au. This was followed by a diamond core drilling program, which returned anomalous zones of gold, and expanded the interpreted greenstone footprint at the project to more than 75km-square.

Salmon Gums is about 200km south of the major regional centre of Kalgoorlie, and 60km south of the mining town of Norseman. It is situated 30km south and along strike, in the same stratigraphy, as Pantoro’s (ASX: PNR) ‘high-grade’ Scotia Gold Project.

Aruma Resources in unique set of circumstances with rare earths find in prospective gold region

Aruma Resources (ASX:AAJ) has found itself in unique set of circumstances following the discovery of rare earth elements while exploring for precious metals in a prospective gold region of Western Australia.

The Perth-based company will descend into Singapore next week to present at the Future Facing Commodities conference where Managing Director Glenn Grayson will discuss the company’s unique greenfields exploration ground in Western Australia.

Held from 4-6 April, the event will feature keynotes, panels, and presentations on commodities such as lithium, uranium, rare earths, among others.

Speaking to Mining.com.au ahead of the trip, Grayson says Singapore is emerging as a source of capital for the resource industry and the conference is set to unite investors with exploration and mining companies focused on the energy transition.

This conference is the first one Aruma has done that exposes us to the Southeast Asian market. This will expose Aruma to a whole new set of investors with potentially very deep pockets.”

The MD adds such the event offers an ideal platform to convey to investors that Aruma has “exciting projects with a diverse commodity target”.  The company currently has 5 projects in Western Australia – a lithium asset and 4 gold projects.

While the company has predominantly been exploring for gold, Grayson says it has uncovered rare earth elements (REEs) at its 100% owned Saltwater Gold Project. Under the common models in which REEs are generally found, those associated with sedimentary rocks can also be associated with gold and base metals, meaning uncovering REEs is not actually that rare.

The MD adds, having exposure to such a future facing commodity is an exciting proposition for Aruma.

“The lithium has given Aruma great exposure in the current lithium market. The REE targeting at a very under-explored area at Saltwater, and with the banking turmoil, the gold focus at Salmon Gums has created a unique set of circumstances that places Aruma in a really good place for success.

We peg ground based on our understanding of the geology and the model of mineralisation that we are wanting to explore for. Great work does not always return orebodies if the ore isn’t in the ground. But pegging the right ground for the wrong reason can happen. The good work is recognising what in fact could be there and changing to explore for other minerals or commodities. I don’t believe in keeping blinkers on in search for one commodity when other value could be there.”

“I don’t believe in keeping blinkers on in search for one commodity when other value could be there”

Grayson notes that it is not uncommon to discover REEs when exploring for gold within sedimentary rocks. The chemistry of the fluids that scavenge gold from the sedimentary rocks also scavenge (or dissolve) other metals. The fluid could be fertile with multiple elements and it is the reaction of the fluid during deposition of the metal and the interaction with the final host rock that defines which mineral or commodity is deposited.

On 15 February, Aruma reported it will aggressively pursue the REE potential at the Saltwater Project in the Pilbara region of Western Australia. The company plans to undertake a targeted fieldwork program at Saltwater designed to position Aruma with a first mover advantage in what is an emerging REE province.

The Saltwater Project consists of 4 granted Exploration Licences (EL52/3818, EL52/3846, and EL52/3857) over a total area of 450km-square and is situated some 100km south-west of the regional mining centre of Newman.

The project was originally pegged by Aruma in 2020 for its gold prospectivity, based on the reactive stratigraphy adjacent to the Nanjilgardy Fault within the project area that controls about 6 million ounces of known gold mineralisation along its entire strike.

Dreadnought Resources (ASX:DRE) has accumulated a major landholding at its Bresnahan REE Project immediately adjacent to Saltwater where significant initial light and heavy REE results have been delivered.

Aruma Resources begins next phase of drilling at Salmon Gums Gold Project in WA

Aruma Resources (ASX:AAJ) has begun the next phase of drilling at its Salmon Gums Gold Project, following up on previous bonanza grade gold intersections.

The company reports this phase of drilling will consist of 47 reverse circulation (RC) holes for 5,500m, and a 1,026 sample shallow auger drilling program.

The RC program is designed to follow-up previously recorded ‘high-grade’ intersections, as well as testing ‘strong’ coincident gold and arsenic in soil anomalies to extend the current known gold mineralised areas at the Iris and Thistle prospects. The auger drilling program is designed to further test the soil anomalies, particularly south of the Thistle prospect, with the aim of extending the project’s gold footprint.

Aruma reports the targeted anomalies have been defined by 15 parts per billion (ppb) gold and 30 parts per million (ppm) arsenic. The soils in the area have been ‘extensively’ re-worked through decades of farming, but significantly past drilling has proven this to be a reliable targeting method for gold mineralisation.

The company says the auger program will provide more ‘effective’ testing for gold mineralisation and other elements at depth below that of a standard soil sampling program. In addition to gold, the auger program is planned to begin in early April, and both programs are expected to be completed in April.

Commenting on the drilling program, Aruma Resources Managing Director Glenn Grayson says: “Salmon Gums is our flagship gold asset and a core exploration focus for the company. We are delighted to commence the 2023 drilling campaign, which will follow-up our previous bonanza grade gold intersections and seek to extend the high-grade mineralised area at the Iris and Thistle prospects.

In addition, the auger drilling program will seek to extend the project’s mineralised footprint, particularly in the southern extent of the project. We see the Salmon Gums Project as having excellent potential to host significant Norseman-style high-grade gold mineralisation, and we eagerly anticipate the results of these drilling programs.”

“We are delighted to commence the 2023 drilling campaign, which will follow-up our previous bonanza grade gold intersections…”

Aruma reports previous drilling at the project intersected ‘bonanza’ gold grades as high as 228g/t Au, with hole SRC39 intersecting 5m @ 50.2g/t Au in 2022.

This drilling was followed by a diamond core drilling program which returned anomalous zones of gold and expanded the interpreted greenstone footprint at Salmon Gums to more than 75km-square.

The company then completed an airborne high-resolution magnetic survey and ground gravity survey over the project area in the current quarter which helped to scope the full extent of the Salmon Gums Greenstone and enhance the lithological and structural understanding at Thistle and Iris. The survey results have been used to help define targets for the current phase of drilling at the project.

Aruma reports geological consultants Model Earth have been engaged to interpret the detailed aerial magnetic survey and ground gravity survey. The company says Model Earth has a ‘strong’ depth of understanding of the geology and mineralisation at the Scotia Gold Project, situated to the north of Salmon Gums.

The company notes Model Earth will utilise their expertise to assist in the geological modelling and assessment of Salmon Gums.

Aruma Resources is an ASX-listed minerals exploration company focused on its portfolio of prospective gold and lithium projects in Western Australia. These projects include the Salmon Gums Gold Project in the Eastern Goldfields, and the multi-commodity Saltwater Project in the Pilbara region.

The Salmon Gums project comprises exploration licences EL63/2037 and EL63/2122, as well as exploration licence application ELA63/2303 which covers an area of 360km-square. The project is located about 200km south of Kalgoorlie, and about 60km south of Norseman.

Aruma Resources encounters further ‘high-grade’ lithium-rubidium intersections at Mt Deans Project, WA

Minerals exploration company Aruma Resources (ASX:AAJ) reports it has encountered further ‘high-grade’ intersections at the Mt Deans Lithium-Rubidium Project in Western Australia.

These assays were recorded from the recently completed second phase of drilling, which comprised 21 reverse circulation (RC) holes for 1,409m to a depth of between 20m and 120m.

Assays returned from 19 holes completed in this drilling, plus the results from 7 historic holes that were re-assayed returned Li-Rb grades in excess of 2%, with a total of 12 intersections with grades over 1.5%.

New ‘high-grade’ results encountered include MDRC0011 with 8m @ 1.89% Li2O+Rb2O from 26m; MDRC0014 with 5m @ 1.51% Li2O+Rb2O from 55m; and MDRC0016 with 2m @ 1.51% Li2O+Rb2O from 26m.

Aruma says this drilling has confirmed and extended the lithium and ‘high-grade’ rubidium intersected in multiple pegmatites in the company’s first phase of drilling in the central part of the project area.

The company reports broad spaced drilling and surface sampling conducted in 2022 identified a thick vertical sequence of lithium and ‘high-grade’ rubidium bearing pegmatites over a strike length of about 1.5km at Mt Deans. All assays for this program were all validated from the second phase of drilling.

broad spaced drilling and surface sampling conducted in 2022 identified a thick vertical sequence of lithium and ‘high-grade’ rubidium bearing pegmatites

Based on the continuing positive results from drilling and exploration activities at Mt Deans, Aruma reports it may look to identify micaceous pegmatites with ‘high-grade’ lithium-rubidium-caesium-potassium (Li-Rb-Cs-K) ore, which may potentially be capable of being concentrated using simple froth floatation and gravity circuits.

The company says this could produce a saleable lithium-potassium (Li-K) concentrate with valuable Rb and Cs by-products with possible tin (Sn) and tantalum (Ta) gravity concentrates.

The wholly owned Mt Deans Project is located in the Mt Deans pegmatite field, located within the Eastern Goldfields Terrane of the Yilgarn Craton in Western Australia. The project lies about 170km south of Kalgoorlie and approximately 10km south of Norseman in Western Australia.

Aruma Resources is an ASX-listed minerals exploration company focused on the exploration and development of a portfolio of gold and lithium projects located in gold mineralised belts in Western Australia.

The company’s projects include the Mt Deans Lithium Project, the Salmon Gums Gold Project, the Saltwater Gold Project, and the Melrose Gold Project.

Aruma Resources unearths anomalous gold mineralisation at wholly owned Melrose Project, WA

ASX-listed minerals exploration company Aruma Resources (ASX:AAJ) reports it has uncovered anomalous gold mineralisation following a maiden drilling program at its Melrose Gold Project in Western Australia’s Pilbara region. 

The results, generated by 48 drillholes for 4,784m of reverse circulation (RC) drilling, have identified gold mineralisation hosted within an oxidised shale, as well as anomalies on an east-west structural target at the Gossan Hill Prospect. 

Results also confirm that the low-grade mineralised host is in contact with the coarse greywacke, a fine siliceous sulphidic siltstone. 

It is reported that drilling targeted the Gossan Hill prospect, which is located 5km from the Paulsens Gold Mine, which was acquired by Black Cat Syndicate (ASX:BC8) from Northern Star Resources (ASX:NST). 

The company also notes that the contact investigated in its drilling is on a shale-dolomite contact which shares similarities to the Mt Olympus and Paulsens gold projects in the region. 

Aruma has expanded the Melrose project area through the award of the balloted exploration licence E08/3499

In addition, Aruma announces it has expanded the Melrose project area through the award of the balloted exploration licence E08/3499, which comprises 7 blocks over a 20km-square area.

This tenement is host to the Mt McGrath Gold Project and is reported to contain gold in veins, close contact of the Wyloo Group Mt McGrath Formation pelites and Hamersley Marra Mamba Iron Formation cherts. 

Meanwhile, the company advises it has also received an R&D tax incentive refund of about $830,677 (before costs) for the 2020-21 year. This amount represents 43% of allowable research carried out by the company using its recently registered “Mineralisation Model Incorporating Volcanic Ash Sequences” research project. 

Aruma Resources is an active and focused junior exploration company that is currently focused on the exploration and development of its 3 wholly owned gold projects, the Saltwater and Melrose projects in Western Australia’s Pilbara region, as well as the Salmon Gums Project in southeast Western Australia.   

The Melrose project is located 105 km south of the mining town of Pannawonica, which is situated on the border of the Ashburton and West Pilbara Mineral Fields. Melrose is reportedly situated on the same regional structure that is believed to be the main source of gold mineralisation at the Paulsens and Mt Olympus Gold Mines.    

With the maiden RC drilling program at the Melrose project now complete, Aruma Resources announces it plans to undertake a mapping program and chip sampling program on historic geophysics as a next phase of exploration at the project.

Aruma Resources launches next phase of drilling at Mt Deans Lithium-Rubidium Project in Western Australia

Aruma Resources (ASX:AAJ) reports that the next phase of drilling has started at its 100% owned Mt Deans Lithium-Rubidium Project (P63/2063) in the lithium corridor of south-eastern Western Australia.

Drilling will consist of 1,500m-1,800m of reverse circulation (RC) drilling across in 12 to 15 holes, to depths of 80m-120m.

Aruma notes that the program is designed to follow-up the ‘high-grade’ lithium and rubidium intersected in the thick vertical pegmatite in Aruma’s first phase of drilling, and a subsequent rock chip sampling program.

The current phase of drilling is expected to be complete in mid-October and results will be released when available.

“Initial indications from the first hole of the program indicate several pegmatites in the northern section of the project”

Initial indications from the first hole of the program indicate several pegmatites in the northern section of the project, which may warrant additional holes. High lepidolite content has been noted in the first holes and this is the target mineral for Li-Rb content.

Aruma reports it has secured a specialised drill rig for the second phase drilling, enabling the holes to be drilled tangential to access tracks and minimise the disturbance of vegetation.

The access tracks at Mt Deans run north-to-south and the specialised blasthole rig will utilise these tracks to drill east-west holes, to test the extent of the thick lithium-rubidium dyke intersected in the Company’s previous drilling at Mt Deans.

Aruma targeted the priority Mt Deans ‘main section’ in its first phase of drilling, which comprised a total of 1,156m of RC drilling in 8 holes.

Aruma Map

This drilling delivered ‘highly’ encouraging results including high-grade rubidium. Lithium grades of up to 1.14% Li2O (lithium oxide) were intersected within a wide zone of lithium, all within a near-surface 25m thick, vertical body of solid pegmatite, from a depth of just 17m.

The first phase of drilling defined an interpreted strike length of at least 1,500m, which remains open at both ends. The program returned more than a dozen intersections grading higher than 0.5% Li2O, and also returned rubidium, grading up to 1.05% Rb2O (rubidium oxide), with elevated tin, tantalum, and cesium.

Aruma followed up its first phase of drilling with a rock chip sampling program designed to test for strike extensions to the interpreted pegmatite zone and help refine targets for the second phase of drilling.

This program returned ‘high-grade’ lithium of up to 1.96% Li2O and ‘very high-grade’ rubidium of up to 1.42% Rb2O, plus cesium values up to 1550ppm.

A total of 11 rock chip samples along a 500m strike were collected, and the results indicated a strong positive relationship with the first-phase drilling results.

Aruma Resources to commence maiden drilling program at Mt Deans project

Aruma Resources Limited (ASX: AAJ) has announced plans for the maiden drilling program at its 100%-owned Mt Deans Lithium Project in Western Australia. The company said that the drilling is planned to commence in the June quarter.

AAJ noted that the limited rock chip sampling program conducted at Mt Deans had delivered exceptionally high lithium, and tantalum results including Lithium oxide (Li2O) grades up to 2.1%; and Tantalum pentoxide (Ta2O5) up to 556 ppm.

Highly prospective Mt Deans project

Mt Deans project is located in Western Australia’s ‘lithium corridor’ in the Eastern Goldfields Terrane of the Yilgarn Craton and is highly prospective for lithium minerals, tantalum and rare earth elements.

The project is interpreted to have similar geology as the significant nearby Mt Marion, Bald Hill, and Buldania Lithium Projects.

Previous work at the project area from 2002, undertaken by Tantalum Australia Ops Pty Ltd had identified swarm pegmatites within the lease over a 1.5km strike length.

The Mt Deans area has a swarm of 71 recognised pegmatites covering 4.5 by 1.5 kilometres trending north north-west. The pegmatites range from 500 to 2,000 metres in length and 0.3-7.5 metres thick, with a few 20 metres thick.

High-grade results from rock chip sampling program

The company had conducted a limited rock chip sampling program at Mt Deans project. AAJ said that the program delivered exceptionally high lithium and tantalum results, with lithium (lithium oxide – Li2O) grades of up to 2.1% and tantalum (tantalum pentoxide – Ta2O5) of up to 556ppm in sample AR003.

The company noted that these compare favourably with similar deposits. AAJ said that strongly anomalous rare earth results were also reported from the rock chip sampling program.

Drilling planned at Mt Deans

The company has now announced the plans for its maiden drilling program at the Mt Deans project. AAJ said that the drilling is targeted at an interpreted “Cauldron” type anomaly which is at the confluence of the east and west dipping pegmatite limbs.

Aruma said that it plans to investigate the potential for the Project to host direct shipping lithium ores, given its location adjacent to the Coolgardie- Esperance Highway and rail infrastructure which provides direct access to the Port of Esperance rail hub – and the potential for transport and infrastructure advantages.

Phase 1 drilling in June

Aruma announced that it plans to undertake the first phase of drilling at the Mt Deans Project in the June quarter 2021.

AAJ said that its first phase of drilling at Mt Deans will target the junction of known pegmatites within the Project area as the possible cauldron target. The drilling is designed to test for spodumene and other lithium minerals, plus tantalum, tin, and rare earth minerals.

12 RC holes planned

The company said that it plans to drill an initial 12 RC holes in the first phase of drilling at the Mt Deans Project, to a maximum hole depth of 200 metres and with drill holes spaced approximately 120 metres apart, to intersect the possible cauldron or pegmatite chamber.

POW submitted; CMP approved

The company said that in preparation for drilling, it has submitted a Program of Works (PoW) with the Western Australian Department of Mines, Industry Regulation and Safety (DMRIS) for the initial 12-hole RC (Reverse Circulation) drilling program. AAJ said that the Conservation Management Plan (CMP) has been submitted and approved.

AAJ noted that site access to the drill targets already exists on old tracks, and drilling will commence upon approval of the PoW.

Management statements

Aruma managing director Peter Schwann said: “Aruma is of the view that the previous lithium results plus the high-grade tantalum and rare earth elements results, together with the infrastructure advantages afforded by the Project’s location make Mt Deans a highly exciting lithium exploration opportunity.

We look forward to commencing our first pass drilling program at the Project as soon as the PoW is granted.”

Aruma Resources identifies further anomalous gold mineralisation at Melrose project

Aruma Resources Ltd (ASX: AAJ) announced that highly anomalous gold samples were identified from the sampling at its Melrose gold project in the Pilbara region of Western Australia.

The company said that these further highly anomalous gold mineralisation come from two new licence – ELA08/3244 and ELA47/4414. AAJ reported that ELA08/3244 hosts 0.5m-wide quartz veins assaying up to 1.74g/t Au, while ELA47/4414 has rock chip assays grading up to 0.36g/t Au.

Aruma noted that the gold anomalies are on the same structure as that of Northern Star’s Belvedere Prospect. The company announced that the conductivity and Mapping studies are underway to define alteration and mineralisation.

Melrose project

The Melrose Gold Project consists of seven Exploration Licence Applications (ELA08/3183, ELA08/3184, ELA08/3188, ELA47/4362, ELA08/3219, ELA47/4414, and ELA08/3244) and covers a total area of 185km2. It is located approximately 105 km south of the mining town of Pannawonica on the border of the Ashburton and West Pilbara Mineral Fields.

The Melrose Project is situated on the southern edge of the Pilbara Craton, adjacent to Northern Star Resources’ Paulsens Gold Mine and the Belvedere Deposit.

The Paulsens Deposit was discovered and mined in the early 1930s and was then called the Melrose Mine. It is situated in a +3M oz. gold camp and most production have come from multiple lodes at the Paulsen Mine.

Modern evaluation and mining of the Paulsens mine by NuStar Mining Corporation commenced in May 2004 and the Paulsens process plant poured the first bar in June 2005.

In July 2010, Northern Star Resources took over the mine and successfully mined it until late 2017 producing up to 100,000 oz. Au per year through both existing and new ore shoots.

Since 2017 Northern Star has relinquished areas in the Paulsens district following initial exploration, and these areas represent the ground that Aruma has appraised, using “gold in sediment” models to seek stratigraphic repetitions in favourable structures associated with the Nanjilgardy Fault.

ELA47/4414 and ELA08/3244

Exploration Licence Applications ELA47/4414 and ELA08/3244 are located within the Melrose project and cover a total of 19km2 area.

It may be noted that ELA08/3244 hosts gold mineralisation within quartz veins, as reported in Northern Star Resources’ 2012 Annual Exploration Report on the Ashburton Project.

Further highly anomalous gold results from sampling

The company announced that the latest results from the two new Exploration Licence Applications ELA47/4414 and ELA08/3244, have delivered highly anomalous historical gold samples up to 1.74g/t in quartz veins as well as rock chips assays.

“Significant results included 1.74ppm Au (NPGER000889) from south west of the Belvedere Prospect. Elevated copper, up to 25% (NPGER000821), is located through the areas and is often associated with the gold mineralisation in quartz veins.”

Same regional structure as Paulsens

The company noted that the Melrose Project is situated on the same regional structure reported as the main source of gold mineralisation at the nearby Paulsens Gold Mine, and also the Mt Olympus Gold Mine in the region.

The Melrose project covers these gold bearing structures and stratigraphy, which are intimately associated with the 1 million-ounce Paulsens Mine. The structural corridors that control the mineralisation at Paulsens appear to continue into Aruma’s Melrose Project area.

Most of the reported historic drilling and sampling was conducted on east-west traverses at a spacing that Aruma believes has left windows of opportunity for the discovery of further gold mineralisation.

Potential lode systems

Aruma said that the significance of the quartz veins in the new lease area is that they are expected to be associated with adjacent lode style gold mineralisation.

AAJ reported that it will be utilising these veins to identify any associated lodes systems.

Conductivity and mapping studies to define further alteration and mineralisation

Aruma reported that it has now commenced a HyVista multispectral mineral mapping and Radar conductivity study, as well as the Aster Thermal mineral mapping program over a targeted 80km2 area within the Melrose Project area.

The company said that this mapping program over known mineralisation will utilise the pre-mining spectral data and this method and approach also has the potential to be deployed by Aruma to help target gold forming alteration and mineralization at its other project areas.
