Investment ViewAuroch Minerals Ltd (ASX: AOU) is a nickel sulphide focused base-metal resource company building value through targeted high-impact exploration in Western Australia.
AOU has three nickel projects in Western Australia, one of the world’s richest regions for nickel sulphides.
AOU’s nickel projects all sit in the Norseman-Wiluna Greenstone Belt, home to some of the best nickel projects globally including Leinster, Mt Keith, Kambalda and Widgiemooltha.
All of AOU’s projects, including Leinster and Saints are highly prospective for near surface, high grade nickel sulphide mineralisation.
The Nepean Nickel Project is AOU’s primary focus.
The Nepean Nickel Project contains the historic high-grade Nepean nickel sulphide mine. There are several highlights:
- Nepean was the second producing nickel mine in Australia
- It produced just over 1.1 million tonnes of ore between 1970 and 1987
- The Nepean nickel mine has a remnant high-grade JORC (2004)-compliant resource: 13,250t contained nickel @ 2.20% Ni (It should be be noted that the resource is JORC(2004) only (i.e. historic estimate) and not compliant with the JORC (2012) code required now).
- High potential to build on the existing remnant resources with drill targets along strike and at depth
- Nepean is a historic nickel sulphide mine constrained at depth by a pegmatite which immediately draws an analogy to Western Area’s (ASX:WSA) Flying Fox nickel mine and the subsequent discovery of Spotted Quoll along strike
- Nepean is <500m deep and has produced over 32kt Ni thus far; Flying Fox is >1,200m and has produced over 100kt Ni so far
You can see the comparison between Nepean and Flying Fox below:
The question now is whether Nepean can become another Flying Fox.
One further highlight is Nepean is 70km from BHP’s Kambalda Nickel Concentrator and Smelter.
Late last year, BHP announced it would be establishing itself as a primary supplier of materials to the battery and electric vehicle markets. In doing so, the company confirmed that it was boosting nickel production in response to Tesla CEO Elon Musk calling for miners to ramp up output of the key material used in the company’s batteries.
The presence of nearby processing facilities operated by third parties, including BHP’s Kambalda smelter, is a substantial benefit for AOU as BHP looks for more nickel supply.
We see multiple share price catalysts on the horizon for AOU:
- Processing agreements: There is a likely prospect of negotiating processing agreements with BHP regarding toll treating and offtake agreements.
- Exploration results: Drill results from known high-grade prospects are imminent.
- Resource definition: The establishment of a maiden resource at Leinster and expansion of the resources at Nepean and Saints.
Reasons why we like AOUThe key reasons for us choosing to invest in AOU are:
- Tight capital structure: AOU does not have many shares on issue. The top 20 shareholders control 33% of the shares. As there is not a lot of free float, the share price could move quickly on positive news
- Potential quick translation from exploration to production. AOU has a head start in terms of transitioning from exploration to production due to its established resources and the likely near term maiden resource definition at the high-grade Leinster Project.
- Proximity to processing facilities. Nepean and Saints are relatively close to BHP’s Kambalda nickel concentrator and smelter, while The Horn (Leinster Project) is only 50 kilometres from BHP’s Nickel West operations at Leinster - in total, there are five processing plants within trucking distance of AOU’s projects.
- Speaking of BHP - AOU would make an ideal target for a suitor such as BHP. Mining giant BHP could boost production on commercially viable terms and has commenced trying to source contracts with Nickel Sulphide deposits to feed into its Nickel West refineries. It has also been in talks with Tesla to increase supply.
- Right region for nickel exploration. Western Australia is one of the world’s largest and richest regions for nickel sulphides.
- M&A activity in the nickel sector? We believe there is the potential for corporate activity in the nickel sector as larger mining groups look to increase capacity in order to attract lucrative offtake orders that come either directly or indirectly from the EV industry.
- Billionaire investor Chamath Palihapitya, the world's most influential financial twitter user after Elon Musk, who made his fortune as an early backer of Google, Facebook, Amazon and Tesla, has an uncanny knack of picking the next huge thing early and recently stated on Twitter that he is now investing in Nickel miners.
- Previous management believed the resource extended beneath the historic mine. Historic drilling beneath the Nepean mine intercepted grades as high as 11.78% Nickel (over 3m). Previous management think this and other geophysical data indicates a high chance that the Nickel deposit continues at depth.
- AOU has existing Nickel resources of over 1.6m ton at 2% Nickel. Recent drill results at Nepean indicate that its resources will increase. Managing Director Aidan Platel believes there is 60,000 ton contained Nickel currently at the Nepean asset.
Nepean Nickel ProjectAOU entered into a binding agreement to acquire 80% of the shares in Eastern Coolgardie Goldfields Pty Ltd (ECG), the company that will hold the Nepean Nickel Project, comprising a package of 13 tenements located 25 kilometres south of Coolgardie, in Western Australia.
Following the acquisition of the remaining 20% by Goldfellas Pty Ltd, AOU and Goldfellas will operate the Nepean Nickel Project as a joint venture with AOU holding an 80% participating interest and Goldfellas the remaining 20%.

The Nepean Nickel Project contains the historic high-grade Nepean nickel sulphide mine, which was the second producing nickel mine in Australia, producing just over 1.1 million tonnes of ore between 1970 and 1987 for about 32,200 tonnes of nickel metal at an impressive average recovered grade of 2.99% nickel.
The ore was treated by Western Mining Corporation (WMC, now BHP Group Ltd) at its Kambalda processing facilities which is still in operation.
The Nepean mine closed in 1987 due to low nickel prices, leaving significant nickel sulphide resources unmined.
And low was very low. At the end of 1986 when a fight or flight decision had to be made, the nickel price was hovering in the vicinity of US$1.60 per pound, about 80% below current levels.
Times have now changed with the nickel price now at over US$7.00 per pound.
The nickel sulphide mineralisation in the Nepean mine is typically massive to semi-massive sulphides with a very high nickel tenor, contained predominantly in two main bodies, Sill 2 (red) and Sill 3 (green) as shown below.
While this gives you an idea of the known, it is more the unknown that intrigues Wise-Owl because what you see above may just be the tip of the iceberg.The following diagram shows a comparison with Western Area’s Flying Fox mine (right side) which is regionally relevant and bears many similarities in terms of mineralisation and structure.
Most significantly, just like Nepean, Flying Fox was constrained by pegmatites at a relatively shallow depth. Flying Fox was constrained at around 300 metres and then at a deeper level of approximately 600 metres, with the latter being consistent with the depth and positioning of the pegmatite below the orebody at Nepean.
As you can see above, deeper drilling at Flying Fox unveiled substantial open mineralisation below the pegmatite wide zones between about the 700 metre and 1200 metre mark.
In addition to the near-mine prospectivity, management believes that Nepean has enormous potential to host further significant nickel sulphide mineralisation, with the 3,128 hectare tenement package hosting over 10 kilometres of underexplored strike of the Nepean mafic-ultramafic mine stratigraphy and/or aeromagnetic anomalies.
The company has identified several high-priority areas, and a 3,500 metre reverse-circulation (RC) drill programme has already yielded some extremely promising results including 3 metres at 3.7% nickel, including 2 metres at 5.1% nickel, as well as one metre at 5.6% nickel.
Two lenses of high-grade massive nickel sulphides, each up to 6 metres thick have now been defined at depths of less than 100 metres for more than 500 metres of strike. All intersections to date have also identified some copper mineralisation.
Twenty drill-holes have been completed for approximately 2,400 metres of the maiden drilling programme at Nepean, comprising 10 shallow near-mine drill-holes and 10 regional drill-holes testing aeromagnetic targets along the 10 kilometres of prospective strike.
With plenty more drilling results to filter through in the coming weeks, there are plenty of catalysts investors can look forward to.
Looking beyond this drilling program, management expects to complete a resource estimate by year-end, enabling it to fast track Nepean to production.
Previous mining has pointed to the prospect of gold and lithium mineralisation, and management will be on the lookout for similar occurrences, though the key focus is on the project’s nickel-copper prospectivity.
What has driven nickel to a seven-year highTowards the end of February this year, nickel hit a near seven-year high as it pushed up towards the psychological US$9.00 per pound mark.
However, as you can see from the chart above, since the start of March the metal has fallen by approximately US$1.00 per pound as concerns arose regarding oversupply from a potential decision by Indonesia that would allow for a restoration in nickel ore exports after a three-year ban.
With these dynamics in play, speculative selling is occurring, effectively boosting inventories.
However, most analysts are of the view that equilibrium will return.
Tesla chief executive Elon Musk commented that nickel was the company’s "biggest concern" in scaling lithium-ion cell production.
Nickel is one of the priority metals in the manufacture of Tesla’s batteries and the car giant is looking to increase its nickel supply.
There may also be some direct investment from other auto manufacturers who have expressed a desire to move to a vertically integrated model whereby they have better control over the supply chain in relation to commodity inputs.
From a longer term perspective, analysts are generally expecting tailwinds for the nickel price due to increasing demand from the electric vehicle industry. The World Bank predicts that Nickel demand is guaranteed to increase by some of the most dramatic figures by tonnes.
This would be good news for AOU in the long-term.
It would appear that both new supply and a loosening in trade barriers are required to meet the uptick in demand.
BHP and Tesla on the same page - what would a deal mean for AOU?While there has been much talk of changes in battery manufacturing, as recently as two weeks ago Volkswagen held its Power Day, reaffirming that lithium, manganese and nickel would be the key commodities used across its battery range.
With regard to supply chain management, Jorg Teichman, VW’s Chief Purchasing Officer said that the group plans to expand the scope of its value chain from purchasing of raw materials directly from miners to making investments in various parts of the supply chain.
Volkswagen declared they will be raising the amount of Nickel used in their electric car battery cells to 80% from current 65% in the next year: moving from 65% Nickel, 15% cobalt and 20% Manganese, to 80% Nickel, 10% Cobalt and 10% Manganese. This is across all their brands including Porsche, Audi and Scania.
Volkswagen is targeting 3 million EVs by 2025, and will be sourcing green Nickel Sulphide from sustainable mines.
As battery metals stocks are seeing a massive surge in investor demand, nickel explorers like AOU that are located in highly prospective regions and in close proximity to established production hubs are likely to attract investor attention on the back of the current surge in nickel demand.
Not only will a company such as AOU be viewed as potentially being able to bring new production to the likes of BHP to coincide with the uptick in nickel demand, but it will also be viewed as a potential takeover target by mid-tier players looking to establish a hub and spoke strategy, or multiple sources of additional feedstock for one of the majors like BHP.
Last year, BHP Nickel West asset president Edward Haegel mentioned the possibility of Tesla using BHP’s nickel supply , of which 70 per cent is already used to develop batteries around the world.
Speaking at the Diggers and Dealers forum in Kalgoorlie, asset president for BHP’s Nickel West subsidiary, Eduard Haegel, said calls by Tesla’s Elon Musk for more nickel production highlighted the scale of opportunity being created by the clean energy sector for materials, but stopped short of confirming that BHP had finalised a nickel supply deal with Tesla.
However, Haegel did say , "Nickel West is well positioned to benefit from this anticipated growth. Last year, we sold around 70 per cent of our nickel to battery manufacturers around the world, making BHP one of the world’s leading battery metal suppliers."
In July last year, Musk said that a "giant contract for a long period of time" would be provided to a miner capable of sustainably extracting nickel due to the high cost of EV batteries.
Musk has confirmed that Tesla already sources lithium from Australia, and it was reported last year that Tesla and BHP were in confidential discussions as the former went public in saying that it is looking to improve battery performance through increased use of nickel in battery production.
While Musk has backtracked in recent days, overall activity in the sector including from VW and statements from billionaire investor Chamath Palihapitya and the World Bank, suggest that the requirement for nickel will continue to increase.
Peer comparisonsRelative to its sulphide nickel peers with commercial grades of 1% or higher (there are only a handful at 2% or higher), AOU would seem undervalued at $65M.
In fact, High grade nickel drill intercepts have seen Australian investors have a huge effect on nickel companies.
PoseidonIn October 1969, rumours of a significant high grade intercept saw Poseidon’s share price rise meteorically. On October 1 1969, Poseidon announced 40m at 3.56%. This saw the share price surge from $0.80 to a high of $280.
Estrella (ASX: ESR)On 8 October 2020, ESR announced a 2.9m massive sulphide intersect and on 4 November the company confirmed assays of 2.5m at 3.66%. Its share price rose from 0.01 to 0.185 and its market cap soared to over $200m.
Legend (ASX: LEG)On 31 March 2020, Legend announced it had intercepted 12.8m of massive Nickel Sulphides. The share price rerated from 21 April on the back of assays of 12.8m at 2.78% Ni.
The share price rerated from 0.06 to 0.18 and the market cap hit close to $400M within a couple weeks.
Azure (ASX: AZS)On 9 November 2020, Azure announced assays of 3.9m at 2.85% Ni. Its share price rose from 0.32 to $1 and its market cap moved to above $300M.
Auroch (ASX: AOU)Looking at AOU in comparison, It is capped at just $65M, but its historical drill core has shown results of 3m @ 11.78% . The share price is yet to recognise just how strong these results are. With plans to drill this target in the coming months, should AOU hit similar grades it could re-rate in line with its peers.
Here’s a look at how Auroch compares with its peers in terms of tonnage and grade:
The AOU teamManagement has the runs on the board when it comes to discovering and developing world-class projects.
Aidan PlatelChief executive Aidan Platel is a geologist with over 20 years’ experience in the minerals industry, traversing both mining and exploration roles across a wide range of commodities.
More recently, Platel has worked as an independent strategic consultant focusing on project evaluation, prior to which he spent 12 years in South America in mining and exploration.
He has a proven track record of exploration success having discovered and developed several major deposits including the world-class Santa Rita Nickel deposit which has contained nickel metal of more than 1 million tonnes. Santa Rita was commissioned by Mirabella which went from a penny stock to a multi-billion market cap.
Trevor EtonNon-Executive Director Trevor Eton was as CFO and Company Secretary of sulphide nickel producer, Panoramic Resources Limited (ASX: PAN) from 2003 to 2020 in which he was instrumental in the financing, construction and development of the Savannah Nickel Project and the acquisition and subsequent development of the Lanfranchi Nickel Project, which saw the company reach a market capitalisation exceeding $1 billion in 2007.
Prior to Panoramic, he held corporate finance roles with various other resource companies, including diversified metal producers, MPI Mines Limited (MPI) and Australian Consolidated Minerals Limited (ACM).
Having Mr Eton on the team shows how serious AOU is about its nickel selling strategy, with his experience in negotiating offtakes with nickel buyers set to come to the fore.
AOU’s other WA nickel projectsWith the acquisition of the Saints and Leinster Projects in late August 2019, AOU narrowed its focus to nickel exploration in the Norseman-Wiluna Greenstone Belt, arguably the best address globally for nickel sulphide mineralisation and home to numerous tier-1 nickel projects.
The acquisitions of the Saints and Leinster projects was perfectly timed as nickel enjoyed a remarkable resurgence, buoyed by a combination of supply pressures, local high-profile acquisitions and discoveries, Tier-1 production restarts and the EV demand juggernaut.
As stated, to support its exploration activity, AOU boosted its geological team.
The strategy bore immediate results with an updated geological model for the Saints project and significant aircore (AC) drilling programmes generating a stream of new basal channel targets (T1-T6), which have the highest probability of hosting thick zones of high-grade massive nickel sulphides and are extremely important for Kambalda-style komatiitic nickel sulphide deposits.
Leinster Nickel ProjectsIn the last six months, AOU has received promising assay results from its maiden diamond drilling program at the Horn Prospect, part of the Leinster Nickel Project.
AOU has flagged a planned drilling campaign at the Horn prospect to commence this month, which is expected to generate additional understanding of the potential here.
Most recently, massive sulphides were delineated within a larger mineralised interval of about 5 metres grading more than 2% nickel and 0.6% copper from the first hole.
The second hole (HNDD002) confirmed thick shallow high-grade nickel-copper-PGE sulphide mineralisation, with the logged massive sulphides interval reporting 7.3 metres at 2.2% nickel, 0.53% copper and 0.64 g/t palladium from 143 metres.
This hole has been very informative for AOU, as it also intersected the massive nickel sulphide mineralisation 15 metres further north along strike from an historic intercept of 14.7 metres at 2.19% nickel and 0.48% copper, effectively extending the mineralisation where previously it was thought to have terminated.
Hole HNDD003 returned a significant intercept of 1.5 metres at 1.5% nickel, 0.4% copper and 0.3 g/t palladium from 135 metres, including a smaller zone of massive sulphides grading 2.4% nickel and 0.5% copper.
However, it wasn’t so much the quality of the grades that were under the spotlight with this hole as it was drilled to test a historic drill hole electromagnetic (DHEM) conductor outside of the known mineralisation.
Consequently, intersecting massive sulphides at a relatively shallow depth is very encouraging in terms of assessing the quality of the data that to varying extents continues to shape exploration in the area.
DHEM surveys have been completed for all holes at the Horn and the geophysical data is currently being processed and modelled.
The results of the DHEM and the detailed geological logging will be used to plan the next stages of exploration at the Horn and surrounding prospects at Leinster.
Saints Nickel ProjectThe Saints Project has a Mineral Resources estimate of just over 1 million tonnes at 2.0% nickel and 0.2% copper for 21,400 tonnes of contained nickel and 1,600 tonnes of contained copper.
October 2019 drilling results featured some very strong nickel grades, most significantly 1.8 metres at 6.7% nickel and 0.27% copper, including 0.5 metres at 10% nickel and 0.24% copper.
Historical drilling results at this site also featured outstanding results over larger intersections such as 31 metres at 1.66% nickel and 0.16% copper, including 10.5 metres at 2.30% nickel and 0.25% copper.
The most recent drilling returned assay results of massive nickel sulphide mineralisation intersected in diamond drill-hole SNDD013.
The results came from the 1,200m diamond drill (DD) programme at the project.
The two main zones returned downhole intersections of 1.25 metres at 3.7% nickel and 0.18% copper from 241 metres, as well as a similar hit at the same depth within a broader mineralised zone of 3.7 metres at 1.85% nickel and 0.26% copper.
Prior to this drilling, there was a distinct lack of data to work with, but now that there are two very compelling drill targets for the next phase of diamond drilling management feels more confident that it can locate the feeder channel mineralisation within the Saints system.
SummaryAOU has transformed itself from a ‘drill and hope’ explorer across various disparate assets, to a nickel company that has a clear vision in terms of creating value through acquisitions, exploration, development and the negotiation of ore processing agreements.
The company’s assets are located in one of the best nickel regions in the world and it has a management team with global experience in discovering, developing and operating +1 million tonne nickel mines.
Under their stewardship it is expected that near-term production can be achieved at Nepean with the likelihood of a resource expansion, and exploration will also elevate the profile of the Leinster and Saints operations.
With five processing plants within trucking distance of AOU’s operations, the company does not have to deal with the traditional capital expenditure and logistical challenges faced by miners bringing new projects into production.
While commodity prices can be volatile, AOU’s exposure to the nickel price appears favourable given the metal’s seemingly attractive medium to long-term demand curve.
While the following table provides a snapshot of what has been delivered in recent months, and what to expect in the near term, AOU’s initiatives are likely to really come to the fore in the second half of 2021 as the company grows and officially establishes a much larger resource across the three assets.
The establishment of a combined resource, as well as the anticipated higher confidence levels that could be attributed to the Saints resource, will provide investors with the data to make peer value comparisons which are likely to indicate that an enterprise value-based share price rerating is warranted.
THE BULLS SAY
- AOU is operating in one of the world’s most prominent nickel endowed regions.
- Having an established resource at Nepean provides a cheap and ready source of ore.
- Nepean also has the capacity to generate near-term cash flow.
- High-grade drilling results suggest there is exploration upside.
- Minimal capital expenditure with access to existing transport and processing infrastructure.
- The macro outlook for nickel is robust.
- If the goal of 100,000 tonnes of contained nickel is realised, it may attract major producers.
- Experienced management team brings a robust focused strategy and early signs of success.
THE BEARS SAY
- There is some overhang in options to be converted at a 10c exercise price, which may hamper share price appreciation until all converted.
- Non-producing explorers are usually viewed as speculative and riskier.
- AOU will need to transition to production for its assets to be valued accordingly.
- With drilling occurring across multiple projects, a capital raising could occur.
- Poor drilling results could dampen investor confidence, placing a drag on the share price.
- Despite the positive macro outlook for nickel, commodity prices are unpredictable.
