Investor Insight
International Lithium offers investors exposure to the growing critical metals sector through its advanced-stage Raleigh Lake lithium-rubidium project in Ontario, early-stage copper-cobalt exploration at Firesteel in Ontario, and strategic focus on Southern Africa, all supported by strong infrastructure and a seasoned leadership team.
With strategic divestments, a robust financial position, and a focused growth strategy, International Lithium is well-positioned to meet the rising demand for lithium and other critical metals
Overview
International Lithium (TSXV:ILC,OTC:ILHMF,FRA:IAH,OTCQB:ILHMF) is a Canada-based mineral exploration company focused on the discovery and development of lithium and other critical metals essential for the transition to a cleaner, greener planet. With a portfolio of projects located in mining-friendly jurisdictions, the company’s primary objective is to build shareholder value by advancing its key assets towards production while expanding its presence in emerging critical metals regions.
International Lithium's flagship asset is the 100 percent owned Raleigh Lake lithium and rubidium project in Ontario. A preliminary economic assessment (PEA) for the Raleigh Lake project, completed in December 2023, demonstrated strong project economics and significant resource growth potential, including an annual after-tax cash flow of C$634 million, NPV of C$342.9 million and IRR of 44.3 percent, with a nine-year mine life and project duration of 11 years. This assessment did not yet include rubidium, which represents significant additional potential pending further market analysis.
Complementing its lithium focus, the company is advancing the Firesteel copper-cobalt project in northwestern Ontario, targeting high-grade base metal mineralization to further diversify its critical metals exposure.
In addition to its Canadian projects, International Lithium is positioning for further international growth with a strategic focus on Southern Africa. It has applied for exclusive prospecting orders (EPOs) in Zimbabwe, one of the world's most prospective regions for hard rock lithium exploration.
Recent strategic divestments, including the sale of the Avalonia project stake, have strengthened ILC's financial position, enabling focused investment in its core projects.
In 2025, International Lithium acquired an option from Lepidico (Canada) Inc. to purchase 100 percent of Lepidico (Mauritius) for C$975,000. Lepidico Mauritius holds an 80 percent stake in Lepidico Chemicals Namibia (Pty) Ltd., which owns the Karibib Lithium, Rubidium and Cesium Project in Namibia.
The project comprises two areas with fully permitted mining licences, known as Rubicon and Helikon. It also hosts one of the largest disclosed rubidium resources in Africa, along with significant lithium and cesium mineralization.
Exercising the Karibib option would position International Lithium to capitalize on an upswing in the lithium market while also cementing its role as one of the leading global players in rubidium. The project would expand its portfolio of some of the most significant cesium resources held by any non-Chinese company, strengthening its standing in three critical minerals that are increasingly vital to global supply chains.
The company is led by an experienced management team with a strong technical background in mineral exploration, project development and corporate finance. Supported by access to established infrastructure, a commitment to sustainable development practices, and a clear strategic focus, International Lithium is well-positioned to capitalize on the increasing global demand for lithium and other essential materials critical to the clean energy transition.
Company Highlights
- International Lithium is focused on developing lithium and critical metals projects in Canada and Southern Africa, aiming to deliver shareholder value through project development, strategic partnerships and project sales.
- Raleigh Lake is ILC’s wholly owned flagship lithium-rubidium project in Ontario, Canada, with a positive PEA completed in December 2023.
- ILC holds a 90 percent interest in the Firesteel copper and cobalt project in Northwestern Ontario, with exploration permits filed and drilling programs planned.
- The company has applied for exclusive prospecting orders (EPOs) in Zimbabwe and is continuing to review further exploration opportunities in Southern Africa.
- ILC is debt-free with a robust financial position. It has monetized its non-core assets, including the sale of its stake in the Avalonia project in Ireland, resulting in a C$2.5 million payment and a 2 percent net smelter royalty.
- ILC secured an option to acquire 100 percent of Lepidico (Mauritius), which owns an 80 percent interest in Lepidico Chemicals Namibia, the owner of the Karibib Lithium, Rubidium and Cesium Project in Namibia.
- The company is led by an experienced management team with a proven track record in advancing mineral exploration projects.
Key Projects
Raleigh Lake
The Raleigh Lake project is ILC’s flagship asset, located approximately 25 kilometres west of Ignace, Ontario. The project covers a contiguous land package of 32,900 hectares and is 100 percent owned by the company. Raleigh Lake benefits from excellent infrastructure access, situated near the Trans-Canada Highway, a Canadian Pacific Railway line, and existing natural gas and hydroelectric infrastructure.
Major public infrastructure relative to the Raleigh Lake project
Raleigh Lake is notable for its dual potential to host both lithium and rubidium mineralization. The lithium is found primarily in spodumene-bearing pegmatites, while rubidium is associated with microcline-rich zones of the same lithium-cesium-tantalum pegmatite system. In 2023, International Lithium published a maiden mineral resource estimate (MRE) that delineated significant resources for both lithium and rubidium using separate cutoff criteria.
For lithium (Li₂O), the project hosts a measured and indicated resource of 5.88 Mt grading 0.79 percent Li₂O, and an inferred resource of 2.07 Mt grading 0.77 percent Li₂O, primarily within pegmatite #1. This lithium resource forms the basis of the company’s PEA, which demonstrated robust project economics with an after-tax NPV (8 percent) of C$342.9 million and an IRR of 44.3 percent.
The rubidium component, though not included in the PEA due to current market constraints, represents an additional potential value stream. The company has reported a measured and indicated resource of 133,000 tons at 6,163 ppm rubidium (0.67 percent Rb₂O) and an inferred resource of 123,000 tons at 4,224 ppm rubidium (0.46 percent Rb₂O), using a 4,000 ppm cutoff. The rubidium zones are found in association with potassic feldspar, offering a potentially recoverable byproduct pending further market and technical evaluation.
Given the project’s strong infrastructure position, mineral endowment, and defined development path, Raleigh Lake represents a compelling advanced-stage opportunity in North America's lithium supply chain. International Lithium is continuing infill and expansion drilling, environmental baseline studies, and metallurgical testing to support project advancement toward pre-feasibility.
Firesteel Project
The Firesteel project is an early-stage copper-cobalt exploration property located in northwestern Ontario, approximately 10 km west of Upsala along Highway 17. Spanning a 16-km corridor to the Firesteel River, the property lies within a geologically favorable region characterized by Archean metavolcanic and metasedimentary rocks, which are prospective for volcanogenic massive sulphide (VMS) and sedimentary copper systems.
International Lithium completed the acquisition of a 90 percent interest in the Firesteel project in May 2024, aiming to diversify its critical metals portfolio beyond lithium. Historical sampling on the property has returned encouraging results, including copper assays up to 2.6 percent and cobalt values reaching 309 ppm. Notably, the "Roadside 1" occurrence features semi-massive sulphide mineralization comprising pyrite, pyrrhotite, chalcopyrite and bornite. These findings suggest the presence of a highly metamorphosed VMS or sedimentary copper system, potentially up to 20 meters wide and extending over a kilometer in length.
The project's proximity to major infrastructure, including highways and railways, coupled with its strategic location near the company's Raleigh Lake project, enhances its development potential. International Lithium plans to conduct systematic exploration, including geochemical sampling and geophysical surveys, to refine targets for future drilling campaigns.
Wolf Ridge Project
Wolf Ridge is a 5,700-hectare grassroots lithium project located 20 km southwest of Upsala and near ILC’s Firesteel copper claims. The area benefits from excellent infrastructure, including proximity to Highway 17, power, and road access.
The project was highlighted by the Ontario Geological Survey (2021–2022) for its standout lake sediment anomalies - among the highest lithium values in the region - indicating strong potential for LCT pegmatite mineralization.

Southern Africa Exploration Initiative
Southern Africa is recognized as a prospective region for hard rock lithium, and International Lithium’s strategic focus reflects a proactive move to establish a presence in this emerging jurisdiction.
As part of its strategy to expand its critical metals footprint, International Lithium has applied for Exclusive Prospecting Orders (EPOs) over several prospective areas in Zimbabwe. The targeted regions are known for hosting spodumene, lepidolite and petalite-bearing pegmatites, indicating potential for significant lithium resources.
Although the EPO applications are still pending approval, the company has already conducted initial due diligence, including geological reviews and desktop studies, to prioritize exploration targets once access is granted. Zimbabwe’s growing importance as a global lithium supplier, combined with favorable mining policies, offers a compelling backdrop for the company's expansion efforts. International Lithium intends to leverage its technical expertise and exploration experience to quickly evaluate and develop these opportunities upon receiving the necessary permits

New mineralised pegmatites identified at Lithium Ridge as exploration drilling commences with SQM
HIGHLIGHTS
- 14 000 metres of Orientated Diamond Drilling ("DD") underway across priority lithium targets.
- High resolution geological mapping and sampling already identifying new pegmatites with visible spodumene mineralisation.
- Programme builds on historical results of up to 2.13% Li₂O along a 6 km mineralised ridgeline.
Anthony Viljoen, Chief Executive Officer, commented:
"The commencement of drilling at Lithium Ridge with our tier-1 joint-venture partner, SQM, is a significant step forward in unlocking one of Namibia's most exciting lithium opportunities. The encouraging historical results of up to 2.13% Li₂O along the 6km ridge line, are already being complemented by a new geological mapping and sampling programme that has identified additional mineralised pegmatites containing visible spodumene crystals. This strengthens our confidence in the scale and quality of the project. The investment by SQM underscores Lithium Ridge's potential and Namibia's growing role in the global supply of critical minerals. We expect this programme to provide the foundation for fast-tracking the project towards development."
Lithium ridge exploration programme
The Lithium Ridge mining licence is located only 35 kilometres from Andrada's producing Uis tin mine and hosts multiple high-priority lithium-bearing pegmatites, with associated tin and tantalum credits.
The current programme is designed to:
- Unlock the full potential of the mineralised ridge and,
- Extend exploration across the wider licence area where new spodumene - bearing pegmatites have been identified.
The 14 000 metre DD programme will comprise approximately 120 orientated holes, to determine the depth extensions and continuity of the extensive mineralisation already identified at surface. Historical work confirmed grades of up to 2.13% Li₂O and metallurgical spodumene recoveries of up to 80%, producing a premium 6.8% Li₂O concentrate with low iron levels. These results were on drill chip samples produced during reverse circulation drilling at Lithium Ridge. (See announcement dated 5 December 2023). This programme is expected to significantly enhance the geological understanding of Lithium Ridge and demonstrate its economic potential as a large-scale, high quality lithium project.

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's Hancock Prospecting acquired the Roy Hill tenements in 1993. 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 to 70 million tonnes of iron ore per year. Success at Roy Hill has made Hancock Prospecting Australia’s most valuable private company at 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 in Western Australia's resource-rich Pilbara region.
Roy Hill has attracted strategic partnerships with major global enterprises: Marubeni (TSE:8002) has a 15 percent equity stake, POSCO Holdings (NYSE:PKX,KRX:005490) has a 12.5 percent stake and China Steel (TPE:2002) has a 2.5 percent stake. 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.
In June 2025, the partners announced a combined investment of US$1.6 billion to develop the Hope Downs 2 iron ore project, a part of the main JV. The project hosts the Hope Downs 2 and Bedded Hilltop deposits, which together will have a total annual production capacity of 31 million tonnes.
Gina Rinehart’s iron ore investments
Gina Rinehart’s iron ore investments in Western Australia extend beyond Roy Hill and Hill Downs to Atlas Iron’s three producing mines and a pipeline of development projects.
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 Mount 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.
As of July 1, 2025, Hancock Prospecting has consolidated its Roy Hill and Atlas Iron under the new name Hancock Iron Ore. The new entity represents combined iron ore exports of about 74 million tonnes per year.
Additionally, Hancock has an earn-in agreement on Legacy Iron Ore (ASX:LCY) and Hawthorn Resources’ (ASX:HAW) Mount Bevan project through its subsidiary Hancock Magnetite Holdings.
At Mount 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 2024. The PFS incorporates a resource estimate totalling 1,291 million tonnes, which was completed by Atlas, and delineates a capital cost of AU$5 billion to develop Mount Bevan.
Completion of the PFS increased Hancock’s stake in the joint venture from 30 percent to 51 percent, with Legacy now holding 29.4 percent and Hawthorn holding 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.
Exploration licences for the Northback project were greenlit by Alberta regulators in May 2025.
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 came in a flurry in 2023 and 2024.
In June 2023, Rinehart’s Hancock Prospecting signed a separate joint venture earn-in agreement for the Mount Bevan magnetite project 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.
In September 2023, 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, Liontown took a hit as the economics for its near-production Kathleen Valley lithium project in Western Australia were affected by high inflation and low lithium prices. In January 2024, Albemarle decided to sell off its 4 percent stake in Liontown. 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 open-pit production in late July 2024, and is expected to produce approximately 500,000 tonnes per year of spodumene concentrate per year. In April of this year, the operation became Australia's first underground lithium mine when it commenced production from its Mount Mann deposit. Liontown plans to fully transition production to the underground mine in its fiscal 2026.
Albemarle's Liontown acquistion 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 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. The deal closed in May 2024.
Shortly after its Liontown and Azure moves, 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 will help Delta Lithium to fund the development of its Mount Ida lithium-gold project, which is adjacent to Hancock's Mount 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 2024. 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.
In May 2025, Vulcan commenced drilling on its first new geothermal energy-lithium well in Landau, Germany, as part of its Phase 1 Lionheart project. The site currently holds four production and re-injection wells and the company aims to add 24 more that will produce hot lithium brine. Vulcan plans to use the new production to increase its geothermal energy production and begin commercial lithium production. In July, Vulcan received US$122 million from the German government to advance its project.
Gina Rinehart’s rare earth metals investments

Through Hancock Prospecting, Gina Rinehart has made investments in some of the world’s most well known rare earth mineral 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, construction ready Nolans project in the Northern Territory, Australia. Rinehart made the investment in December 2022. As of August 20, 2025, Arafura is conducting an AU$80 million tranche 1 financing underway, reporting support from Hancock Prospecting of a currently undisclosed amount.
In April 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 took up a 5.82 percent interest in Lynas Rare Earths, the largest ex-China rare earths producer. The Australian rare earth 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 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 Lynas and MP Materials came after merger talks between the two rare earths behemoths stalled in February 2024. In November 2024, the mining mogul increased her position in MP Materials to 8.5 percent. As for Lynas, she raised her stake to 7.14 percent in July 2024 and then 8.21 percent in January 2025.
In July 2025, the US Department of Defense announced it was taking a stake in MP Materials worth US$400 million in preferred stock and guaranteed a floor price of US$110 per kilogram for neodymium and praseodymium from MP Materials, representing nearly double that of China’s rates as the Trump administration seeks to build the nation's domestic rare earth industry.
The news of the DoD's investment significantly elevated both MP Materials' and Lynas' share prices, with Forbes reporting that the value of Rinehart's holdings in the two companies increased by about US$200 million and US$100 million respectively.
There was previously speculation stirring that Rinehart’s participation in MP and Lynas could renew merger discussions, Reuters reported, and Rinehart's increased positions further raised the possibility of a merger down the road. However, the US Government's major shareholder position in MP Materials makes such an acquisition a long shot.
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 earth explorer is working its district-scale Rocha da Rocha rare earth asset 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 Mining (TSX:ABX,NYSE:B), 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, and has continued to make 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 2024, 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 licence 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) at 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. During Phase 1, 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 has embarked on a AU$1 billion expansion endeavor at Atlas and Roma North 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 received following an uphill battle with a Federal government more interested in 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 4.075 percent.
In late October 2024, 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 (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 2024 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 per 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.
