Lithium exploration and project development company Critical Resources Limited ASX:CRR (“Critical Resources” or “the Company”) is pleased to advise that follow-up drilling targeting the recently discovered Swell Zone at the Mavis Lake Lithium Project in Ontario, Canada has intersected further thick mineralised1 pegmatite zones, adding significant momentum to its current resource growth drilling program.
Highlights
- In-fill drilling continues to strengthen and expand the “Swell Zone” at Mavis Lake, with multiple wide mineralised zones logged down-hole after recent drilling including;
- MF23-214 with mineralised intercepts totaling 67.85m including a continuous 53.6m intercept with visual estimates of spodumene of 10%
- MF23-226 with mineralised intercepts totaling 61.75m with visual estimates of spodumene at 15%
- MF23-225 with mineralised intercepts totaling 33.95m with visual estimates of spodumene at 20%
- The new mineralised intercepts are located along trend from the recently reported diamond drill-holes MF23-207 to MF23-211, which returned intersections of 40-74m at grades ranging from 1.18% Li2O to 1.25% Li2O.
- A series of in-fill drilling intercepts have delineated mineralised widths significantly greater than the current Inferred Mineral Resource Estimate (MRE) and has identified possible new mineralised zones, highlighting the potential to add substantial tonnage to a future MRE.
- Assay results from 15 holes are pending and will be released to market as soon as they become available.
Logged intercepts from recent in-fill drilling, along trend from the breakthrough intercept of 74.4m grading 1.18% Li2O including 32.9m @ 1.81% Li2O (see ASX release, 24 July 2023), have continued to highlight the significance of the Swell Zone discovery. This includes several in-fill intercepts which are an order of magnitude wider than previous Resource modelling.
Current drilling forms part of a resource upgrade drilling program which commenced in June 2023. Through its exploration efforts, Critical Resources is seeking to establish Mavis Lake as the largest single-site, JORC Code 2012 Compliant Lithium Resource in Ontario.
Full exploration results are provided in Appendix 1.
In-fill Drilling
Recent drilling continues to successfully intersect the Swell Zone laterally, towards both the east and west. The Company has deliberately opted for a tight in-fill drill-hole spacing (25-50m spacing) to facilitate conversion of as much of the Resource to the higher-confidence Indicated category as part of a future Mineral Resource upgrade.
The Swell Zone occurs within and extends outside of the current Inferred Mineral Resource Estimate (MRE) shapes and, as such, is expected to add considerable tonnage to a future MRE upgrade.
The Swell Zone is likely emplaced in a remnant shear structure which could be related to regional shear structures. Shearing is located proximally to the pegmatite contacts within the host rock, multiple oriented measurements indicate the direction of the shearing is concordant to the pegmatite emplacement.
The trend of the Swell Zone is becoming more apparent and current drill results illustrate increased understanding of the emplacement, geometry and trend of the mineralised zone.
Figure 1 – Plan view of Mavis Lake with the Figure 3 cross-section reference
While the Swell Zone intercepts contain pervasive spodumene mineralization, the intercepts often contain multiple “core zones” that are characteristic of higher concentrations of spodumene as shown in Figure 2.

In-fill drilling of the Swell Zone is currently tracking towards the east, with recent logged intercepts in drill-holes MF23-225 and MF23-226 highlighting significant growth potential.
Both drill holes intersected mineralised pegmatite two-three times the width of the current MRE shapes, indicating a clear pathway to resource upgrade in terms of both tonnage and category.
Recent drilling has also identified a possible significant new Lower Zone. An initial intercept from drill hole MF23-208 (13.3m at 1.56% Li2O from 343.9m down-hole – refer to ASX Announcement released 21 August 2023) has been interpreted to link with a lower zone intersected in drill-holes MF23-214, MF23-225 and MF23-226.
Key details are shown in Table 1, with the intercept cross-section shown in Figure 3.
The potential new Lower Zone has not been factored in previous resource modelling and presents as an immediate target for follow-up drilling.

CleanTech Lithium
Investor Insight
Executing a well-defined project development strategy for its lithium assets and advancing Direct Lithium Extraction (DLE), CleanTech Lithium is poised to become a key player in an expanding batteries market.
Overview
CleanTech Lithium (AIM:CTL,FWB:T2N) is a resource exploration and development company with four lithium assets with an estimated 2.72 million tons (Mt) of lithium carbonate equivalent (LCE) in Chile, a world-renowned mining-friendly jurisdiction. The company aims to be a leading supplier of ‘green lithium’ to the electric vehicle (EV) market, leveraging direct lithium extraction (DLE) – a low-impact, low-carbon and low-water method of extracting lithium from brine.
Lithium demand is soaring as a result of a rapidly expanding EV market. One study estimates the world needs 2 billion EVs on the road to meet global net-zero goals. Yet, the gap between supply and demand continues to widen. As the world races to secure new supplies of critical minerals, Chile has emerged as an ideal investment jurisdiction with mining-friendly regulations and a skilled local workforce to drive towards a clean green economy. Chile is already the biggest supplier of copper and second largest supplier of lithium.
With an experienced team in natural resources, CleanTech Lithium holds itself accountable to a responsible ESG-led approach, a critical advantage for governments and major car manufacturers looking to secure a cleaner supply chain.
Laguna Verde is at pre-feasibility study stage targeted to be in ramp-up production from 2027. Laguna Verde has a JORC resource estimate of 1.8 Mt of lithium carbonate equivalent (LCE) while Viento Andino boasts 0.92 Mt LCE, each supporting 20,000 tons per annum (tpa) production with a 30-year and 12-year mine life, respectively. The latest drilling programme at Laguna Verde finished in June 2024, results from which will be used to convert resources into reserves.
The lead project, Laguna Verde, will be developed first, after which Veinto Andino will follow suit using the design and experience gained from Laguna Verde, as the company works towards its goal of becoming a significant green lithium producer serving the EV market.
The Company is carrying out the necessary environmental impact assessments in partnership with the local communities. The indigenous communities will provide valuable data that will be included in the assessments. The Company has signed agreements with the three of core communities to support the project development.
DLE Pilot Plant Inauguration event held in May 2024 with local stakeholders and indigenous communities in attendance
The company also has two prospective exploration assets - the Llamara project and Salar de Atacama/Arenas Blancas project. Llamara project is a greenfield asset in the Antofagasta region and is around 600 kilometers north of Laguna Verde and Veinto Andino. The project is located in the Pampa del Tamarugal basin, one of the largest basins in the Lithium Triangle.
Salar de Atacama/Arenas Blancas comprises 140 licenses covering 377 sq km in the Salar de Atacama basin, one of the leading lithium-producing regions in the world with proven mineable deposits of 9.2 Mt.
CleanTech Lithium is committed to an ESG-led approach to its strategy and supporting its downstream partners looking to secure a cleaner supply chain. In line with this, the company plans to use renewable energy and the eco-friendly DLE process across its projects. DLE is considered an efficient option for lithium brine extraction that makes the least environmental impact, with no use of evaporation ponds, no carbon-intensive processes and reduced levels of water consumption. In recognition, Chile’s government plans to prioritize DLE for all new lithium projects in the country.
CleanTech Lithium’s pilot DLE plant in Copiapó was commissioned in the first quarter of 2024. To date, the company has completed the first stage of production from the DLE pilot plant producing an initial volume of 88 cubic metres of concentrated eluate – the lithium carbonate equivalent (LCE) of approximately one tonne over an operating period of 384 hours with 14 cycles. Results show the DLE adsorbent achieved a lithium recovery rate of approximately 95 percent from the brine, with total recovery (adsorption plus desorption) achieving approximately 88 percent. The Company’s downstream conversion process is successfully producing pilot-scale samples of lithium carbonate . As of January 2025, the Company is producing lithium carbonate from Laguna Verde concentrated eluate at the downstream pilot plant - recently proven to be high purity (99.78%). Click for highlights video.
CTL’s experienced management team, with expertise throughout the natural resources industry, leads the company toward its goal of producing green lithium for the EV market. Expertise includes geology, lithium extraction engineering and corporate administration.

Key Projects
Laguna Verde Lithium Project
The 217 sq km Laguna Verde project features a sq km hypersaline lake at the low point of the basin with a large sub-surface aquifer ideal for DLE. Laguna Verde is the company’s most advanced asset.
Project Highlights:
- Prolific JORC-compliant Resource Estimate: As of July 2023, the asset has a JORC-compliant resource estimate of 1.8 Mt of LCE at a grade of 200 mg/L lithium.
- Environmentally Friendly Extraction: The company’s asset is amenable to DLE. Instead of sending lithium brine to evaporation ponds, DLE uses a unique process where resin extracts lithium from brine, and then re-injects the brine back into the aquifer, with minimal depletion of the resources. The DLE process reduces the impact on environment, water consumption levels and production time compared with evaporation ponds and hard-rock mining methods.
- DLE Pilot Plant: The pilot DLE plant in Copiapó, commissioned in the first quarter of 2024, has produced an initial volume of 88 cubic metres of concentrated eluate, which is the lithium carbonate equivalent (LCE) of approximately one tonne further confirming the company’s capacity to produce battery-grade lithium with low impurities from its Laguna Verde brine project.
- Scoping Study: Scoping study completed in January 2023 indicated a production of 20,000 tons per annum LCE and an operational life of 30 years. Highlights of the study also includes:
- Total revenues of US$6.3 billion
- IRR of 45.1 percent and post-tax NPV8 of US$1.8 billion
- Net cash flow of US$215 million
Viento Andino Lithium Project
CleanTech Lithium’s second-most advanced asset covers 127 square kilometers and is located within 100 km of Laguna Verde, with a current resource estimate of 0.92 Mt of LCE, including an indicated resource of 0.44 Mt LCE. The company’s planned second drill campaign aims to extend known deposits further.
Project Highlights:
- 2022 Lithium Discovery: Recently completed brine samples from the initial drill campaign indicate an average lithium grade of 305 mg/L.
- JORC-compliant Estimate: The inferred resource estimate was recently upgraded from 0.5 Mt to 0.92 Mt of LCE at an average grade of 207 mg/L lithium, which now includes 0.44 million tonnes at an average grade of 221 mg/L lithium in the indicated category.
- Scoping Study: A scoping study was completed in September 2023 indicating a production of up to 20,000 tons per annum LCE for an operational life of more than 12 years. Other highlights include:
- Net revenues of US$2.5 billion
- IRR of 43.5 percent and post-tax NPV 8 of US$1.1 billion
- Additional Drilling: Once drilling at Laguna Verde is completed in 2024, CleanTech Lithium plans to commence further drilling at Viento Andino for a potential resource upgrade.
Llamara Lithium Project
The Llamara project is one of the largest greenfield basins in the Lithium Triangle, covering 605 square kilometers in the Pampa del Tamarugal, one of the largest basins in the Lithium Triangle. Historical exploration results indicate blue-sky potential, prompting the company to pursue additional exploration.
Project Highlights:
- Promising Historical Exploration: The asset has never been drilled; however, salt crust surface samples indicate up to 3,100 parts per million lithium. Additionally, historical geophysics lines indicate a large hypersaline aquifer. Both of these exploration results indicate potential for significant future discoveries.
- Close Proximity to Existing Operations: The Llamara project is near other known deposits:
Arenas Blancas
The project comprises 140 licences covering 377 sq km in the Salar de Atacama basin, a known lithium region with proven mineable deposits of 9.2 Mt and home to two of the world’s leading battery-grade lithium producers SQM and Albermarle. Following the granting of the exploration licences in 2024, the Cleantech Lithium is designing a work programme for the project

Extensive Lithium Anomalies defined at Salinas South Project, Lithium Valley, Brazil
Highlights
Work Undertaken
- Encouraging assays were received from 38 stream sediment samples.
- Lithium anomalies were identified over a 5.8 km distance, which includes high order anomalies over an artisanal working.
- Anomalies interpreted to lie over a major concealed granite body at depth.
Figure 1. The Gold Mountain team conducted an extensive stream sampling program across GMN’s Brazilian Lithium, Copper and Rare Earth Projects in 2024 and that program is ongoing in 2025. Sampling methods are adapted to local conditions.
Future Workplan
- Carry out soil sampling over the strongest lithium anomalies with coincident pathfinder element anomalies and the known artisanal working.
- Continue on ground mapping to search for pegmatite outcrops.
- Define drill targets and get environmental permits for drilling.
Managing Director David Evans commented
“Over the past few years, Gold Mountain has built up an impressive ground position in Brazil’s Lithium Valley, an emerging lithium hotspot, home to two producing mines and Latin Resources’ Colina deposit. The new results from Salinas South complement the recent announcement of 10 drill targets from our Salinas II Project and give the company a strong pipeline of targets for us to test right across this highly prospective region.”
Details
Strongly anomalous stream sediment sample results were received on the Salinas South 830.557/2023 tenement with strongly correlated beryllium (Be), rubidium (Rb), niobium (Nb) and potassium (K).
Table 1 shows the correlation chart for the anomalous lithium samples in tenement 830.557/2023
Table 1. Correlation chart for lithium anomalous samples taken on 830.557/2023 showing strong correlations between lithium and other important LCT pegmatite pathfinder elements.
Note that correlations show spatial associations that include lithium pegmatites and may include other rock types. The presence of chrysoberyl in the area suggests that pegmatites have intruded mafic to ultramafic rocks to pick up the chromium necessary to form chrysoberyl rather than beryl. This gives additional criteria to search for lithium pegmatites and explains part of the unusual associated elements in the correlation chart such as Ni, Mg and Zn.
The Salinas South project consists of 26 tenements with a total area of 50,911 hectares in the Lithium Valley. Post tectonic granites surround the tenements which contain favourable weak, schistose host rocks.
The Salinas South Project area is thought to lie on the margins of a major granite at depth, with the margins also passing through the area of the Sigma Resources and CBL lithium mines. A strong NE trending structural direction is also present at the Salinas South Project, similar in direction to those identified at Sigma Lithium and in the vicinity of the Colina deposit held by Latin Resources. The structural directions are also visible on the radiometric and magnetic images of the Salinas South Project.
Structurally controlled occurrences of pegmatites including one known to contain lithium are located just to the northwest of the Salinas South Project area on prominent NE trending structures. Similar orientation structures are seen in the topography in the Salinas South 830.557/2023 tenement.
Mapping in 830.557/2023 during sampling identified an occurrence of pegmatite as well as late tectonic granites. Mapping elsewhere in the Salinas South tenements has also shown that there are significant scale pegmatites present. An artisanal working was identified. It lies within or adjacent to a high order lithium anomaly and is the highest priority target area in this tenement at present.
It was also evident that remnants of an old surface were present on many of the ridges, indicating that subdued anomalies could be anticipated from sources on the hills. Presence of an old lateritised surface indicates where lithium pegmatites may be concealed by leaching of lithium.

Drilling Targets Defined – Bananal Valley tenement, Lithium Valley, Brazil
Highlights
Work Undertaken
- Assays received from 100 and 200 metre spaced soil sampling lines with soil samples taken at 50 metre intervals.
- Lithium anomalies identified over the 1.5 km strike extent of the soil grid with coincident Be, Rb, Sn and Tl anomalies.
- No lithium anomalies found in areas of laterite however tin anomalies as well as quartz and tourmaline occurrences suggest pegmatite extensions under the laterite.
- Drill holes defined so environmental permits can be obtained to allow drilling to take place.
Future Workplan
- Obtain environmental permits for drilling
- Extra soil lines in the NW of tenement to follow up anomalies previously defined
- Continue detailed mapping to refine currently identified pegmatite trends
- Drilling of the lithium targets identified.
Details
Results from exceptionally high value stream sediment sample have been followed up with soil samples and grid based mapping in the southern part of 831.700/2022 and drilling targets had been identified.
Mapping prior to and during soil sampling identifies numerous small pegmatites and some larger pegmatites to a maximum of 10 metres wide. Areas of large quartz boulders, possibly quartz cores to pegmatites, were also mapped and in places are coincident with lithium and lithium pathfinder anomalies. Pegmatites cross cut and are younger than the foliation in the host G3 type granite.
Regional structure from geophysics and from topography shows a strong NE to ENE trend, subparallel to the Latin Resources “Lithium Corridor.” Drilling will be oriented at 90 degrees to the regional trend initially, as the most probable major pegmatite orientation direction.
Strong vertical zonation in the lithium pegmatite geochemical responses are present and close attention to the location of laterite and the old lateritised surface is critical to interpretation of where lithium pegmatites may be concealed by leaching of lithium.
Drill targets were defined by lithium anomalies and by occurrences of pegmatite or extensive float of pegmatite minerals, lithium pathfinder elements, large quartz boulders or anomalous quartz concentrations.
The lateritic weathering zone is estimated from mapping to be up to 50 metres thick within the tenement, but locally may be significantly thicker. Drilling below this weathered layer is essential to get analyses that reflect the actual grade of any pegmatites present. Within the weathering zone low values of lithium are expected from potentially economic pegmatites.
Images & Maps
Figure 1 shows the location of the Salinas Project tenements in relation to Latin resources Collina deposit and to other tenements held by major explorers including Rio Tinto.

This region contains two producing mines, the undeveloped Colina deposit, and several prospects with significant exploration activity. While close proximity does not guarantee similar results it does provide evidence to assist in targeted exploration.
Mapping and soil sampling in the western Bananal Valley tenement, 831.700/2022, has defined areas of laterite as well as various larger pegmatite and quartz occurrences.
Figure 2 shows the extensive high order stream sediment target zones in the Bananal valley tenement, with their follow up soil lines and potential pegmatite mineral occurrences, including green tourmaline, indicating highly evolved pegmatites.

Who is Gina Rinehart?
Gina Rinehart is an Australian iron ore magnate and the executive chair of Hancock Prospecting, as well as the richest person in Australia and one of the world’s richest women. Rinehart is the daughter of Australian mining mogul and Hancock Prospecting founder, the late Lang Hancock. As the current executive chair of Hancock Prospecting, Rinehart won the inaugural Lifetime Achievement Award from CEO Magazine in 2019.
Rinehart was appointed as an Officer of the Order of Australia in 2022 for her “distinguished service to the mining sector, to the community through philanthropic initiatives, and to sport as a patron.”
How did Gina Rinehart get rich?
Gina Rinehart inherited Hancock Prospecting after her father’s passing in 1992. The following year, Gina Rinehart’s company acquired the Roy Hill tenements. Centering the massive project as the cornerstone of the company, Hancock Prospecting has greatly benefited from the iron ore market boom that began in the early 2000s.
Today, Roy Hill is Australia’s largest iron ore mine, producing 60 million tonnes of iron ore per year. The mine was recently approved to increase its annual production to 70 million tonnes. Success at Roy Hill has made Hancock Prospecting Australia’s most valuable private company, worth an estimated AU$15.6 billion.
As with many of the world’s most successful billionaires, Gina Rinehart has developed an investment strategy based on strategic partnerships as well as diversification to mitigate risk and build value. Under her leadership, Hancock Prospecting Pty Limited (HPPL) as well as the HPPL Group of companies has expanded into some of the world’s most economically important markets, such as real estate, agriculture, energy and critical metals.
For the 2024 fiscal year, Rinehart's Hancock Prospecting reported a bumper profit of AU$5.6 billion, up 10 percent from the previous year.
What mining companies does Gina Rinehart own?
Through her company Hancock Prospecting, Gina Rinehart owns interest in mining companies across many sectors, including iron ore, lithium, rare earths, copper, oil and gas, as well as potash. While much of her investment portfolio is focused on Australia and ASX companies, Rinehart is actively strengthening the geographical diversification of her investments.
In recent years, Rinehart has made a series of key investments in mining companies, especially targeting critical metals projects in Germany, Brazil, Ecuador and the United States. These include exploration-stage firms such as Titan Minerals (ASX:TTM) and Azure Minerals as well as producers such as Atlas Iron and MP Materials.
Where does Hancock Prospecting mine iron?

Hancock Prospecting’s Roy Hill and Hope Downs iron ore mines are located in the resource rich Pilbara region of Western Australia.
Roy Hill has attracted strategic partnerships with major global enterprises: Marubeni (TSE:8002) with a 15 percent equity stake; POSCO (NYSE:PKX,KRX:005490) holds a 12.5 percent stake; and China Steel (TPE:2002) has a 2.5 percent equity position. The minority partners purchase a combined 28.75 million tonnes of iron ore annually from Roy Hill’s production.
In September 2024, Hancock Prospecting got the green light for its AU$600 million McPhee iron mine located about 100 kilometres north of the Roy Hill mine after a long approval process. The McPhee iron mine is expected to produce around 10 million tonnes of the metal each year over an estimated 15 year mine life. First production is expected to kick off next year, and ore will be transported by road trains to Roy Hill for processing and blending. The goal is to improve the larger mine's product mix and sustain its production volumes.
The Hope Downs iron ore complex is another of Australia’s largest iron ore projects. A 50/50 joint venture partnership with Rio Tinto (ASX:RIO,NYSE:RIO,LSE:RIO), Hope Downs hosts four open-pit mines and has an annual production capacity of 47 million tonnes. Hope Downs has also been the subject of a more than decade-long civil dispute in a Western Australian court over royalties, put forth by the descendants of Lang Hancock's business partner Peter Wright as well as Rinehart’s own children.
Gina Rinehart’s iron ore investments
Gina Rinehart’s iron ore investments in Western Australia extend beyond Roy Hill and Hill Downs to its subsidiary Atlas Iron’s three producing mines and a pipeline of development projects, as well as an earn-in agreement on Legacy Iron Ore (ASX:LCY) and Hawthorn Resources’ (ASX:HAW) Mt Bevan project through its subsidiary Hancock Magnetite Holdings.
Rinehart’s Hancock Prospecting acquired Atlas Iron in 2018 through a AU$427 million deal that turned out to be dirt cheap as the company would go on to deliver AU$1.5 billion in revenues over the next three years alone.
Today, Atlas Mines operates the Mt Webber, Sanjiv Ridge and Miralga Creek mines. Production from these mines in its fiscal year ended June 2023 led to a AU$222 million dividend payment for Rinehart’s Hancock Prospecting.
At Mt Bevan, as part of its earn-in agreement, Hancock completed a prefeasibility study (PFS) for a 12 million tonne per year high-grade magnetite project in July of 2024. The PFS incorporated a mineral resource estimate totalling 1,291 million tonnes, which was completed by Atlas, and delineates a capital cost of AU$5 billion to develop the potential Mt Bevan mine.
Completion of the PFS increased Hancock’s stake in the JV ownership from 30 percent to 51 percent with Legacy now holding 29.4 percent and Hawthorn 19.6 percent.
Like iron, coal is another essential material in steel manufacturing. To this end, Rinehart is also pursuing an investment in a past-producing metallurgical coal mine in Alberta, Canada. Hancock Prospecting subsidiary Northback Holdings is the owner of the proposed Grassy Mountain steelmaking coal project in the province’s Crowsnest Pass region. Northback is awaiting approval of its exploration licenses for the project.
Gina Rinehart’s lithium investments
Gina Rinehart's lithium investments include Azure Minerals’ (ASX:AZS) Andover lithium project, Liontown Resources, Delta Lithium (ASX:DLI) and Vulcan Energy Resources (ASX:VUL). The majority of her lithium investments have came in a flurry over the past year.
In June 2023, Rinehart’s Hancock Prospecting signed a separate joint venture earn-in agreement for the Mt Bevan magnetite project, which is discussed above, this time for the lithium, nickel and copper mineralization at the project. The agreement will similarly see Hancock able to earn a 51 percent interest by completing certain milestones.
Last September, Rinehart made headlines when she took a position in Liontown Resources and then rapidly increased the position to 19.9 percent over the following month. This allowed Hancock, which was now Liontown's largest shareholder, to effectively block Albemarle’s (NYSE:ALB) accepted takeover of the smaller lithium company.
However, since then, Liontown’s stock has taken a hit as the economics for its near-production Kathleen Valley lithium project in Western Australia have been damaged by the effects of high inflation and low lithium prices. Ultimately, in January, Albemarle decided to sell off its 4 percent stake in Liontown Resources. The lack of any further moves or comment by Rinehart in relation to Liontown Resources has led to speculation she may be waiting for the right opportunity to buy up the lithium company at a discount.
Kathleen Valley entered production in late July 2024, and is expected to produce approximately 2.8 million tonnes per year of spodumene concentrate by the end of FY 2027.
That wasn't the only lithium bid Rinehart blocked in October 2023. As is her strategy, Rinehart scooped up an 18.9 percent stake in Azure Minerals last year after SQM announced its intention for a total takeover of the company and its Andover lithium project in the West Pilbara region of Western Australia. This story had a different ending, though, as Hancock Prospecting instead joined the lithium giant in a AU$1.7 billion deal to become a co-owner of the exploration-stage Andover project, which also hosts nickel, copper and cobalt mineralisation. The deal closed in May 2024.
Shortly after its Liontown and Azure moves last year, Hancock Prospecting continued investing in Western Australia's lithium prospects when it participated in a AU$70.2 million fundraising for Delta Lithium in November 2023. The proceeds of the fundraising will help Delta Lithium to fund the development of its Mt Ida lithium-gold project, which is adjacent to Hancock's Mt Bevan joint venture project. As of November 2024, Hancock Prospecting owns 10.65 percent of Delta Lithium.
Rinehart has made lithium investments outside of Australia as well. Looking further afield to Germany, with a 7.5 percent stake, Hancock Prospecting is the second largest shareholder in Vulcan Energy and its flagship Zero Carbon lithium project in Germany’s Upper Rhine Valley, a milestone Rinehart's company reached after investing an additional AU$20 million in Vulcan, which made headlines in June. The Zero Carbon project is slated to produce an initial 24,000 tonnes of lithium hydroxide by the end of 2025, targeting Europe’s electric vehicle manufacturing sector.
In November 2024, Vulcan Energy reached another major milestone with first production at its downstream lithium hydroxide optimisation plant, which is designed to produce lithium hydroxide and battery-grade lithium hydroxide monohydrate.
Gina Rinehart’s rare earths investments

Through Hancock Prospecting, Gina Rinehart has recently made investments in some of the world’s most well known rare earths producing companies — US-based MP Materials and Australia’s Lynas Rare Earths — as well as development-stage Arafura Rare Earths and exploration-stage Brazilian Rare Earths (ASX:BRE). Rinehart taking a position in these rare earths companies shows she is looking to capitalise on the significant need for these critical metals outside of China.
As mentioned in the introduction to this article, Rinehart’s Hancock Prospecting is the largest shareholder of Arafura Rare Earths, giving it a 10 percent stake in the advanced-stage Nolans project in the Northern Territory. Rinehart made the investment in December 2022.
In April of 2024, Rinehart made two significant moves into the sector. The first came on April 9, when it was revealed that Hancock Prospecting had acquired a 5.3 percent stake in MP Materials, the second largest rare earths producer outside of China. The company’s California-based Mountain Pass mine is the only integrated rare earth mining and processing operation in North America.
Rinehart’s investment in MP Materials could later bring in “Roy Hill-type cash flow,” Dylan Kelly, head analyst at Terra Capital, told Australian Financial Review. “Anything that is producing and not China-aligned is highly strategic. These materials are very, very hard to make and there’s a lot of demand in making magnets for electric vehicles and wind turbines."
One week later, Rinehart’s Hancock Prospecting also took up a 5.82 percent interest in Lynas Rare Earths, the largest ex-China rare earths producer. The Australian rare earths miner produces the critical metals at its Mount Weld mine in Western Australia and ships the raw material to Malaysia for processing. Lynas is also ramping up processing at its Kalgoorlie rare earth processing facility in Australia, and building light rare earths processing facilities and a heavy rare earths separation facility in Texas, US.
Rinehart’s near simultaneous investments in both Lynas and MP Materials comes after merger talks between the two rare earths behemoths stalled in February. There is speculation stirring that Rinehart’s participation could renew merger discussions, Reuters reported. In November, the mining mogul increased her position in MP Materials to 8.5 percent, further raising the possibility of a merger down the road.
Andy Forster, Lynas investor and senior investor of Argo Investments, had his interest piqued by Rinehart’s move "given she's clearly made a play across the whole space. She obviously wants to potentially have a seat at the table if there's any chance of consolidation."
Rinehart is also getting her foot in the rare earths door at the exploration level. In 2023, Rinehart’s Hancock Prospecting made a pre-IPO investment for a 5.85 percent share in Brazilian Rare Earths, which went on to list on the ASX in December of that year. The rare earths explorer is working its district-scale Rocha da Rocha rare earth province in the state of Bahia, Brazil. The province is highly prospective for both heavy and light rare earths, with grades of over 40 percent total rare earth oxides found. Brazilian Rare Earths is working to complete an updated JORC mineral resource estimate.
Gina Rinehart’s copper investments
Gina Rinehart’s copper investments are centered on Ecuador’s Andean copper-gold belt, and include explorer Titan Minerals and Ecuador's state-owned Empresa Nacional Minera (ENAMI).
Ecuador has seen a rush of major mining companies taking up positions in key copper and gold projects in recent years, placing Hancock Prospecting in the company of Barrick Gold (TSX:ABX,NYSE:GOLD), Zijin Mining (HKEX:2899) and Anglo American (LSE:AAL,OTCQX:AAUKF).
Rinehart’s Ecuadorian copper investments are in line with her shift toward the critical metals necessary for the green transition and her strategy to expand the global footprint of her mining empire.
Hancock Prospecting subsidiary Hanrine Ecuadorian Exploration and Mining has been in the region since 2017, but recently began making more investments. In March 2024, Hancock Prospecting subsidiary Hanrine Ecuadorian Exploration and Mining acquired a 49 percent stake in six mining concessions for AU$186.4 million. The deal sees it partner with state mining company ENAMI for the concessions, which surround the stalled Llurimagua copper-molybdenum project in Northern Ecuador.
In late April, Ecuador’s constitutional court nixed appeals by ENAMI and its partner in the Llurimagua project, Chile’s state-owned CODELCO, to review the March 2023 decision by Imbabura’s provincial supreme court suspending the environmental license for Llurimagua.
Shortly after the investment with ENAMI, Rinehart's Hanrine made another play in Ecuador by striking an earn-in agreement with Titan Minerals for up to an 80 percent ownership stake in the explorer’s Linderos copper-gold project contingent on up to AU$120 million in exploration spending. Linderos is an early-exploration stage project with the potential to host a large-scale copper porphyry system. Hanrine has made an initial investment of AU$2 million for a 5 percent stake.
Gina Rinehart’s oil and gas investments
Gina Rinehart’s oil and gas investments include private firms Warrego Energy in Western Australia and Senex Energy in Queensland.
In February 2023, Hancock Prospecting won a protracted bidding war for the then-public Warrego with Warrego's joint venture partner Strike Energy (ASX:STX) for a price of AU$0.36 per share. Warrego and operator Strike Energy maintain their 50/50 joint venture on the West Erregulla onshore gas field within exploration permit EP 469 near Perth in Western Australia.
In mid-August 2024, the West Erregulla project received its production licence and the partners expect to start operations once a final investment decision is made later this year. During phase one, the project is expected to produce 87 terajoules per day.
As for Senex Energy, it is a joint venture between POSCO (50.1 percent) and Hancock Prospecting subsidiary Hancock Energy (49.9 percent) that holds the Atlas and Roma North natural gas developments in Queensland’s Surat Basin. The two JV partners acquired Senex in 2022, with Rinehart’s company putting up AU$440.89 million.
Senex Energy is embarking on a AU$1 billion expansion endeavor at Atlas and Roma North this year that will see 60 petajoules of natural gas delivered to Australia’s east coast market annually by the end of 2025. This figure represents more than 10 percent of the region’s demand. Regulatory approval for the expansion was finally approved following an uphill battle with a Federal government more keen on renewable energy projects than the natural gas variety. Hancock Prospecting reported the first flows of gas production from the expansion field in late November 2024.
Rinehart once had a significant stake of nearly 20 percent in Lakes Oil, now Lakes Blue Energy (ASX:LKO), through subsidiary Timeview Enterprises. Timeview's stake in Lakes Blue Energy has been lowered in recent years, but it remains the company's fourth largest shareholder at 4.63 percent.
In late October, Rinehart offered financial assistance to Mineral Resources (ASX:MIN,OTC Pink:MALRF), a diversified mining company with lithium, iron ore and oil and gas operations in Western Australia. Headed by another mining heavyweight, Chris Ellison, Mineral Resources, or MinRes, is reportedly drowning in debt and embroiled in a tax evasion investigation. At that time, Hancock Prospecting agreed to a AU$1.13 billion buyout of MinRes' oil and gas projects in the Perth Basin and an exploration acreage in the Carnarvon Basin.
The 100 percent sale of two of MinRes' exploration permits to Hancock was completed in December for initial consideration of AU$780 million, with potential for up to AU$327 million depending on whether certain conditions and thresholds are met. The permits include the Moriarty Deep prospect and the Lockyer gas and Erregulla oil discoveries.
Separate to that sale, the two companies are also forming two 50/50 exploration joint ventures for MinRes' remaining permits in the Perth and Carnarvon Basins. Hancock will acquire 50 percent of the MinRes Explorer drill rig, which is the largest in Australia.
Gina Rinehart’s potash and agriculture investments
Gina Rinehart’s potash and agricultural investments center on Hancock Prospecting’s ownership interests in multiple premium cattle stations in Australia, and the company's royalty revenue generated from the Anglo-American-controlled Woodsmith potash project currently under construction in the United Kingdom.
With an original investment of AU$380.6 million in 2016 to then-owner Sirius Minerals, Hancock Prospecting has a 5 percent revenue royalty on the first 13 million tonnes of fertiliser produced from Woodsmith and 1 percent thereafter. Hancock also has a 20,000 tonne-a-year offtake option. The timeline for Rinehart’s royalty revenue has been pushed back, however, as Anglo is cutting spending at Woodsmith following BHP’s (ASX:BHP,NYSE:BHP,LSE:BHP) failed mega-merger with Anglo American.
Investor takeaway
With Gina Rinehart at the helm of Hancock Prospecting, the Roy Hill iron ore mine has generated stellar revenues. That wealth creation not only made her Australia's richest person, but has also built a powerful war chest from which Rinehart is expanding her mining empire.
Investors can take cues from her recent and future moves in the mining sector. Although she may be defensive toward renewable energy technologies encroaching on agricultural land, she understands the strategical importance of investing in critical metals for the green transition such as lithium, rare earths and copper.
