Aluminum Stocks

Rio Tinto is one of the world's largest diversified mining and metals companies. Since the operating model change announced in August 2025 it reports three product groups, Iron Ore, Aluminium & Lithium, and Copper, with the Borates and Iron & Titanium businesses moved outside the product groups for strategic review. The aluminum business is fully vertically integrated from bauxite mining through to primary aluminum smelting, encompassing bauxite mines — principally Amrun and Weipa in Queensland, Gove in the Northern Territory, and operations in Guinea — alumina refineries including Queensland Alumina Limited and Yarwun in Australia, the Vaudreuil Alumina Refinery in Canada, and ISAL in Iceland, and a portfolio of primary aluminum smelters across Canada, Australia, Iceland, and New Zealand, including BC Works (Kitimat, Canada), ISAL (Iceland), Tiwai Point (New Zealand), and multiple smelters in Québec. In 2025, Rio Tinto produced a record 62.4 Mt of bauxite, approximately 7.6 Mt of alumina, and approximately 3.3–3.4 Mt of primary aluminum.

The aluminum business is a source of both ongoing cash generation and long-term low-carbon positioning: Rio Tinto is a 50/50 JV partner with Alcoa in ELYSIS — developing inert anode technology that would eliminate direct CO₂ emissions from the smelting process. NZAS secured new 20-year electricity agreements in May 2024, underwriting operations to 2044. For investors, Rio Tinto's aluminum segment provides meaningful leverage to primary metal and alumina prices within a diversified portfolio primarily driven by iron ore earnings; a re-rating of the aluminum segment is closely tied to energy transition demand growth and eventual ELYSIS commercialisation.

China Hongqiao Group is one of the world's largest aluminium producers and China's largest privately controlled one, a Hong Kong-listed Shandong group running an integrated chain from overseas bauxite through alumina refining to smelting and downstream processing. On its 2025 annual results the group sold approximately 5.824 Mt of aluminium alloy products, broadly flat on 2024, and approximately 13.397 Mt of alumina products, up 22.7% year on year, for revenue of about RMB 162.4 billion. Alumina is therefore not a sideline here: Hongqiao sells more tonnes of it than of metal, which makes the group a beneficiary of tight alumina markets that squeeze buyers such as Press Metal.

China's capacity ceiling shapes everything else. Chinese primary aluminium output reached about 44.23 Mt in 2025, roughly 59.6% of global output of 74.23 Mt, and the company describes the industry as gradually approaching the production capacity ceiling set by supply-side reform. New electrolytic capacity is not permitted, so an incumbent's compliant quota can be relocated but not expanded, which turns Hongqiao's existing entitlement into a scarce asset rather than a growth lever. That is what drives the second theme: moving smelting from coal-fired Shandong to Yunnan, where the group has opened a green and low-carbon industrial park, the Wenshan smart aluminium project and an integrated wind, solar and storage scheme whose first photovoltaic phase reached full-capacity grid connection during 2025. For a Western investor the practical point is access: Hongqiao trades on the Hong Kong main board, so it is reachable without a Stock Connect broker, unlike Yunnan Aluminium.

Hindalco Industries is a Mumbai-listed integrated aluminum and copper producer — the metals flagship of the Aditya Birla Group and, together with its wholly owned subsidiary Novelis, the world's largest aluminum company by revenues and the global leader in flat-rolled aluminum products and aluminum recycling. Novelis is the world's largest aluminum rolling and recycling company. FY2026 (year to March 2026) rolled product shipments were 3,557 kt, down 5% year on year, with recycled scrap the majority of its metal input. End markets span automotive body sheet, beverage packaging, aerospace, and battery foilstock for EV applications.

The centrepiece strategic investment is Bay Minette, Alabama — a US$5 billion integrated recycling and rolling mill with total finished goods capacity of 600,000 tpa, with cold mill commissioning underway as at Q1 2026. The Oswego, New York hot mill, the largest aluminium rolling mill in the United States, was taken offline by a fire on September 16, 2025. A restart planned for December 2025 was pushed out by a second fire on November 20, 2025 in the area being repaired, and the mill came back online on June 10, 2026. Novelis put the FY2026 adjusted EBITDA impact of the Oswego interruptions at approximately US$104 million, of which about US$53 million fell in the March 2026 quarter. In January 2026, Hindalco announced a ₹21,000 crore Indian smelter expansion. US Section 232 tariffs, raised to 50% in June 2025, are a headwind for Novelis's Canadian exports to the US market; Bay Minette's US-domestic position is strategically amplified by the tariff environment.

Norsk Hydro is a Norwegian, Oslo-listed aluminum and renewable energy company with one of the broadest and most deeply integrated positions in the global aluminum value chain — spanning bauxite mining and alumina refining in Brazil (Paragominas mine and Alunorte refinery, the world's largest alumina refinery outside China), primary aluminum smelting in Norway powered by hydropower, downstream extrusions, and recycling. Hydro's strategic identity is built around the green aluminum transition: its Norwegian smelters run entirely on renewable hydropower, it produces Hydro CIRCAL recycled aluminum from a minimum 75% post-consumer scrap, and it is developing HalZero, a smelting process that emits oxygen in place of carbon dioxide.

The Extrusions segment — the world's largest aluminium extruder — has faced headwinds from soft European construction and automotive demand, and Hydro announced restructuring of its Hungarian extrusion plant in early 2026. Qatalum (Qatar, 648,000 tpa nameplate, 50/50 JV with QAMCO) began a controlled shutdown in March 2026 after QatarEnergy warned of a suspension of gas supply amid regional instability. Once the supplier confirmed it would keep supplying at reduced volumes, Qatalum halted further curtailment and held production at around 60% of capacity from March 2026 through the June 2026 quarter. In July 2026 Hydro agreed long-term framework conditions with the Slovak government, including indirect carbon cost compensation, clearing the way to restart 75,000 tpa at Slovalco from the fourth quarter of 2026 for around EUR 100 million, subject to European Commission approval of the Slovak compensation scheme. For investors, Hydro is the most compelling listed vehicle for exposure to the green aluminum premium alongside a large, cash-generative integrated upstream business.

Vedanta Aluminium Metal is India's largest aluminium producer, demerged from Vedanta Limited and listed on the NSE and BSE on June 15, 2026, with integrated alumina refining and smelting operations concentrated in Odisha and Chhattisgarh. The asset base is three sites: the Jharsuguda smelter in Odisha, at about 1.8 Mtpa the largest single-location aluminium smelter in the world, with 3,615 MW of captive thermal generation attached; the Lanjigarh alumina refinery in Odisha, rated at 5 Mtpa after the Train II expansion completed in the first quarter of FY2026; and Bharat Aluminium Company (BALCO) at Korba in Chhattisgarh, which reached 1 Mtpa of smelting capacity in the third quarter of FY2026. FY2026 output was 2.46 Mt of aluminium and 2.9 Mt of alumina, more than half of India's primary production.

The demerger split Vedanta Limited into separately listed aluminium, power, oil and gas, and iron and steel companies on a 1:1 basis, so aluminium investors now hold the metal directly rather than through a diversified holding structure. The distinguishing feature against the other integrated producers on this page is power: Jharsuguda and BALCO run on captive coal-fired generation rather than the hydropower behind Norsk Hydro, Rio Tinto and Yunnan Aluminium, which gives VAML a cost position anchored to domestic coal and a carbon intensity at the high end of the global cost curve. Bauxite security is the other structural question: Lanjigarh has historically depended on third-party and imported bauxite, with no captive mine at scale.

Aluminum Corporation of China Limited (Chalco) is China's dominant state-controlled aluminum producer and one of the largest integrated aluminum companies in the world, listed on both the Hong Kong Stock Exchange (HKEX: 2600) and Shanghai Stock Exchange (SHA: 601600). Chalco spans the full aluminum value chain: bauxite mining, alumina refining (17.35 Mt of metallurgical-grade alumina in 2025, up 2.9% on 2024), primary aluminum smelting (8.08 Mt of primary aluminum in 2025, up 6.2% on 2024), downstream fabrication, and engineering services, alongside copper mining at the Toromocho mine in Peru. Chalco also produces high-purity aluminum, aluminum anodes, gallium metal, and graphitised cathodes.

The most significant near-term catalyst is the CBA acquisition: in January 2026 Chalco and Rio Tinto announced a definitive agreement to jointly acquire Votorantim's 68.6% controlling stake in Companhia Brasileira de Alumínio (CBA) for approximately US$902.6 million (Chalco 67%, Rio Tinto 33%), adding approximately 364,500 tpa of primary aluminum and 800,000 tpa of alumina refining capacity, all powered by 100% renewable energy. Nine-month 2025 revenue was CNY 176.5 billion; Q3 2025 net profit surged 90% year-on-year. Note: Chalco has no US-listed ADR and is accessible to Western investors only via HKEX H-shares (2600.HK).

Press Metal Aluminium Holdings is Southeast Asia's largest primary aluminium producer, smelting on Sarawak hydropower and running an extrusion business alongside the smelters. Nameplate smelting capacity is 1.08 Mtpa across two Sarawak sites: Mukah at 120,000 tpa and the Samalaju complex at Bintulu at 960,000 tpa over three phases. Power comes from long-term agreements with Sarawak Energy drawn on the state's hydroelectric system, which is the basis for the low-carbon GEM brand the company launched in 2024. Downstream, Press Metal extrudes aluminium profiles in Malaysia and China.

Alumina is the structural weakness and the main thing to watch. Press Metal holds 40% of Japan Alumina Associates in Australia, roughly a fifth of Hong Kong-listed Nanshan Aluminium International (2610.HK), taken in a 2024 swap of its 25% stake in PT Bintan Alumina Indonesia and listed in March 2025, and 80% of PT Kalimantan Alumina Nusantara, a refinery under construction in West Kalimantan. Those interests covered roughly 40% of its alumina requirement as at 2025. The rest is bought on the market, so unlike Rio Tinto, Alcoa and Norsk Hydro, which refine their own, Press Metal takes the full margin hit when alumina prices spike and the full benefit when they fall. Cheap hydropower on one side and bought-in alumina on the other is the whole shape of the earnings.

South32 is a diversified mining and metals company spun out of BHP in 2015 that has agreed to exit the aluminium industry, selling its aluminium value chain to Alcoa under a binding conditional agreement announced on June 30, 2026. The agreement covers the Boddington bauxite mine and Worsley Alumina in Western Australia, the Hillside smelter and idled Bayside property in South Africa, the MRN bauxite mine (subject to pre-emptive rights held by its partners) and the Alumar alumina refinery and aluminium smelter in Brazil. On the June 30, 2026 announcement, consideration is approximately US$4.1 billion upfront, US$3.1 billion of it in cash and the balance in Alcoa shares, plus a contingent value right of up to US$750 million running over four annual periods from July 1, 2026; Alcoa described the transaction as US$4.1 billion in enterprise value. It remains conditional on shareholder and regulatory approvals and had not completed as at August 2026.

Mozal Aluminium in Mozambique is excluded from the Alcoa transaction. It was placed on care and maintenance in March 2026 after South32 could not agree an affordable electricity tariff, and the company has said a separate divestment is under consideration. Until the Alcoa sale completes South32 remains a major alumina and primary aluminium producer, with Worsley a long-life, low-cost alumina asset and Hillside a competitive smelter. For investors the implication is a change of kind rather than degree: South32 is now a seller of aluminium rather than a long-term operator, reweighting toward copper, zinc and manganese, with the Hermosa project in Arizona and the Sierra Gorda mine in Chile among the assets it is keeping.

Yunnan Aluminium Co., Ltd. is a Shenzhen-listed Chinese aluminum producer that has positioned itself as China's leading practitioner of green, low-carbon hydropower aluminum. Headquartered in Kunming, Yunnan Province, the company became part of the Chinalco group in December 2018. All of its electrolytic aluminum production capacity is located in Yunnan Province, where abundant hydropower, wind, and solar resources provide exceptionally low-cost and low-carbon electricity — in H1 2025, approximately 84.5% of Yunnan's power generation came from renewable sources. On the company's own H1 2025 disclosure it operates 3.08 Mtpa of electrolytic aluminum capacity at approximately 96% utilisation, alongside 1.4 Mtpa of alumina and 1.61 Mtpa of aluminum alloy and processing products. These figures come from Shenzhen exchange filings and are not independently audited to the standard of the Western reporters on this page.

Downstream products include aluminum foil (one of China's largest ultra-thin foil manufacturers), round aluminum rod, casting alloy ingots, and high-precision aluminum for aerospace, rail, electronics, and defence. Yunnan Aluminium is not listed on any Western exchange. International investors reach it through the Shenzhen-Hong Kong Stock Connect northbound channel, subject to broker eligibility and RMB exposure.

Alcoa Corporation is a NYSE-listed, Pittsburgh-headquartered aluminum producer operating across two primary segments — Alumina and Aluminum — with a global asset base spanning bauxite mines, alumina refineries, and primary smelters across Australia, Canada, Spain, Norway, Brazil, Saudi Arabia, and elsewhere. Alcoa completed the acquisition of Alumina Limited in 2024, consolidating full ownership of the AWAC (Alcoa World Alumina and Chemicals) joint venture and materially simplifying its corporate structure.

Key 2025 operational milestones include the permanent closure of the Kwinana alumina refinery in Western Australia (September 2025, ~US$890 million restructuring charge); the partial restart of San Ciprián in Spain via a 75/25 JV with IGNIS, with approximately 65% capacity achieved by end-2025; and the restoration of full capacity at Lista in Norway. The San Ciprián smelter restart was completed on 7 April 2026, and capacity restarts at Lista and at Portland in Australia were completed during the first half of 2026. Production records were set at five smelters across Canada, Norway, Australia, and the US. Alcoa is also a 50/50 partner with Rio Tinto in the ELYSIS inert anode venture, and in July 2026 took a final investment decision, alongside government and industry partners in Australia, Japan and the United States, on a gallium production plant to be co-located at its Wagerup refinery in Western Australia.

On 30 June 2026 Alcoa entered into a definitive agreement to acquire South32's bauxite, alumina and aluminum interests in Australia, Brazil and South Africa, referred to as AliGroup, for upfront consideration of approximately US$4.1 billion, comprising US$3.1 billion in cash and about 17.0 million newly issued Alcoa shares worth roughly US$1.0 billion, plus a contingent value right of up to US$750 million payable over four annual periods if average alumina or aluminum prices exceed agreed strike prices. Alcoa has described it as the largest transaction in the company's history, and sized the assets at roughly 5.2 million tonnes of annual alumina capacity and approximately 900,000 tonnes of primary aluminum capacity, pro forma increases of 53% and 37% respectively on the June 2026 announcement. The transaction remains conditional on a South32 shareholder vote and regulatory approvals, and had not completed as at August 2026.

National Aluminium Company (NALCO) is an Indian state-controlled producer, 51.28% owned by the Government of India, with captive bauxite, alumina refining and smelting inside a single Odisha complex. The Panchpatmali mine in Koraput district is rated at 6.825 Mtpa of bauxite and feeds the Damanjodi refinery 14 km away by cable belt conveyor. Damanjodi is rated at 2.1 Mtpa of alumina, with a brownfield fifth stream adding 1 Mtpa to take it to 3.1 Mtpa; pre-commissioning began in June 2026. The Angul smelter is rated at 460,000 tpa and runs on a 1,200 MW captive coal-fired power plant supplied by captive coal mines. FY2026 revenue from operations was Rs 17,843 crore and profit after tax was Rs 5,816 crore.

NALCO is the one constituent here that is geared more to alumina than to metal. The smelter consumes roughly 920,000 tonnes of alumina a year against 2.1 Mtpa of refining capacity, so well over half of refinery output is sold externally, and bauxite and alumina sales rather than metal drove the FY2026 revenue line. Captive bauxite at Panchpatmali puts the refinery low on the global cost curve. Against that, Angul's captive coal generation places NALCO at the carbon-intensive end of the producers on this page, alongside Vedanta Aluminium.

Century Aluminum is a NASDAQ-listed pure-play primary aluminum smelter operator — the largest primary aluminum producer in the United States — with smelting operations in the US (Sebree, Kentucky and Mt. Holly, South Carolina; ~450,000 tpa US nameplate at full capacity) and Iceland (Grundartangi, ~317,000 tpa, powered by renewable hydropower and geothermal energy), and a 55% ownership stake in the Jamalco alumina refinery in Jamaica. The company is the most direct beneficiary among listed US aluminum stocks of the Section 232 tariff escalation — raised to 25% in March 2025 then to 50% in June 2025 — which directly drove the decision to restart idled Mt. Holly capacity with a ~US$50 million investment announced in 2025. Century completed that restart in late June 2026, returning Mt. Holly to full capacity, and restarted Grundartangi's Line 2, lost to the October 2025 transformer failure, at the end of July 2026. On completion in June 2026 management sized the Mt. Holly project at close to 10% of total US primary aluminum production and over 150 added full-time jobs at the plant.

In January 2026 Century agreed to develop the Oklahoma greenfield smelter at Inola as a joint venture with Emirates Global Aluminium, which holds 60% to Century's 40%. The plant is sized at 750,000 tpa, which would be the largest primary aluminum plant ever built in the United States and the first since 1980. It is supported by an award of up to US$500 million made by the Department of Energy's Office of Clean Energy Demonstrations in 2025. The grant is secured but milestone-gated: it releases roughly dollar for dollar against investment Century makes into the project. As at August 2026 the project had not reached a final investment decision, and a long-term power supply agreement with Public Service Company of Oklahoma had not been concluded. Power price is the binding constraint on a US greenfield smelter, and as at the Q2 2026 results management named the final energy contract, detailed engineering and financing as the three milestones standing before a final investment decision. Q4 2025 results were impacted by a Grundartangi equipment failure (October 2025, US$30.9 million net charge) and Hurricane Melissa striking Jamaica (US$10.4 million in recovery costs). Jamalco restarted in late Q4 2025 and is undergoing a US$34 million capital programme beginning April 2026. Its new TG4 power turbine came online in early August 2026, allowing the refinery to run on self-generated power and reduce its draw from the Jamaican grid. At 30 June 2026 Century held liquidity of US$785 million and net debt of US$98 million, having repaid US$66 million of its Icelandic revolver in the quarter; it received a US$94 million Section 45X advanced manufacturing production credit refund for 2025 in July 2026.

Chuangxin Industries is a Hong Kong-listed Chinese producer of electrolytic aluminium and alumina, operating an integrated chain from captive power through refining to smelting at Huolinguole in Inner Mongolia and Binzhou in Shandong. The company listed on the Main Board of the Hong Kong Stock Exchange on November 24, 2025, selling 500 million shares at HK$10.99 to raise about HK$5.5 billion gross, the largest Hong Kong aluminium-sector listing of the year by funds raised. Cornerstone investors included China Hongqiao and Glencore. Electrolytic aluminium capacity was 788,000 tpa at the end of 2025, wholly owned, alongside 1.2 Mtpa of alumina refining held at 58.5%. On CRU's measure the Huolinguole smelter was the fourth-largest electrolytic aluminium production base in North China by output in 2024.

The company markets itself as a green aluminium producer, and that description should be read against the asset base rather than the branding: Huolinguole sits in Inner Mongolia, where captive coal generation has supplied the smelter, and the wind and solar capacity intended to displace it is being built with roughly 40% of the November 2025 IPO proceeds. The integrated energy-to-metal structure is the genuine cost advantage today; the carbon position is a construction project, not a current state. Scale is the other caveat: at well under a million tonnes Chuangxin is a fraction of Hongqiao or Chalco, so it is a leveraged play on Chinese aluminium spreads rather than a diversified producer.

Constellium is a NYSE-listed global manufacturer of high-value-added aluminum rolled and extruded products, with no upstream smelting or mining operations — it purchases primary and recycled aluminum and converts it into finished semi-fabricated products for aerospace, automotive, packaging, and industrial customers. The company operates 25 manufacturing facilities across Europe and North America, organised into three segments: Aerospace & Transportation (A&T), Packaging & Automotive Rolled Products (P&ARP), and Automotive Structures & Industry (AS&I). A new CEO, Ingrid Joerg, took over from Jean-Marc Germain on January 1, 2026.

The company completed a major investment in new aluminum foilstock finishing lines at its Singen, Germany plant for battery applications in the European EV supply chain, and is advancing the UK government-backed CirConAl project to develop high post-consumer scrap content aluminum extrusion alloys for automotive. For investors, Constellium's position at the downstream end of the value chain, where metal cost is largely passed through and earnings track conversion margins, makes it a distinct exposure from primary smelters. The key demand drivers are commercial aerospace OEM production rates (A&T), the aluminum can market (P&ARP), and European automotive volumes (AS&I).

Aluminium Bahrain (Alba) runs one of the world's largest single-site aluminium smelters, a gas-powered complex in Bahrain majority owned by the kingdom's sovereign wealth fund. Nameplate capacity is above 1.62 Mtpa following the Line 6 expansion, which added 540,000 tpa to a plant that had run at roughly 1 Mtpa. Alba buys its alumina rather than refining it, so like Press Metal it carries full exposure to the alumina price while its own cost base is set by Bahraini gas rather than hydropower or coal. That places it in the middle of the carbon curve on this page: cleaner than captive coal in India or Inner Mongolia, well above the hydropower smelters in Norway, Canada and Sarawak.

Ownership is the other distinguishing feature. Bahrain Mumtalakat Holding, the sovereign wealth fund, holds about 69%, and Saudi Arabian Mining Company (Ma'aden) acquired SABIC's 20.62% stake in February 2025, leaving roughly 10% in public hands. The free float is therefore small, and control sits with two Gulf state-linked shareholders. Alba is dual listed: the ordinary shares trade on Bahrain Bourse, and the global depositary receipts shown here trade in US dollars on the London Stock Exchange, which is the practical route for most non-Gulf investors.

Kaiser Aluminum is a NASDAQ-listed manufacturer of semi-fabricated aluminum products, with no upstream smelting or mining operations — it purchases primary and recycled aluminum and converts it into finished products for aerospace, automotive, packaging, and industrial customers. The company operates manufacturing facilities across North America and serves end markets including aerospace plate and sheet, beverage canstock, automotive body sheet, and industrial extruded shapes. Its Aerospace & High Strength Products and Packaging Products segments are the primary revenue drivers.

Kaiser's position at the downstream end of the value chain, with earnings driven by fabrication premiums and conversion margins, makes it a distinct exposure from primary smelters. Long qualification cycles for aerospace alloys and beverage can specifications raise switching costs and lend some visibility to volumes, though they do not shield margins from end-market volumes. The key demand drivers are commercial aerospace OEM production rates, the aluminum can market, and automotive sheet volumes.

Metro Mining is an Australian bauxite producer operating the Bauxite Hills mine on Cape York in northern Queensland, shipping direct-shipping ore to refineries in China. Bauxite Hills sits in the Weipa bauxite province alongside Rio Tinto's Amrun and Weipa operations. The ore is mined free-dig and shipped without beneficiation, which keeps capital intensity low and makes the operation unusually sensitive to freight and transhipment logistics. Shipments run through the offshore floating terminal Ikamba; when it went to dry dock in 2026, monthly volumes fell sharply and then recovered by 45% in May 2026 once full transhipment capacity was restored, which is a fair illustration of where the operating risk sits.

Bauxite Hills shipped a record volume in calendar 2025, in the range of 6.5 to 7.0 million wet tonnes. For investors, Metro is the closest thing on this page to a pure bauxite price play: no refining, no smelting, no downstream, and therefore direct exposure to the seaborne bauxite market that Chinese refiners buy from, with none of the integrated producers' natural hedge.

Tredegar Corporation is a NYSE-listed industrial manufacturer operating two distinct businesses: Aluminum Extrusions (via its Bonnell Aluminum subsidiary) and High Performance Films. For investors focused on aluminum, Bonnell Aluminum is the relevant segment: a custom aluminum extrusions producer serving the North American building and construction, automotive, and specialty industrial markets, with manufacturing facilities across the eastern United States. Full-year 2025 consolidated revenue was US$722.9 million, up from US$598 million in 2024, driven primarily by higher Aluminum Extrusions volume and metal cost pass-through; full-year net income from continuing operations was US$24.1 million.

Bonnell's net new orders rose 36% in Q1 2025 against Q1 2024, which management attributed to continued recovery from a downcycle it believed bottomed in Q3 2023, not to tariffs; the company said at the time it had seen no adverse demand impact from tariff actions. The Section 232 rate increase to 50% in June 2025 then weighed on net new orders through H2 — the CEO explicitly noted the 50% rate "continues to exert a negative influence on the domestic extrusions market" as of early 2026. Net debt ended 2025 at US$28.4 million, down from US$54.8 million a year earlier. Tredegar is a niche, small-cap stock offering relatively pure-play exposure to the North American aluminum extrusions market, with the complexity of the unrelated High Performance Films segment.

Canyon Resources is an Australian-listed developer of the Minim Martap bauxite project in Cameroon's Adamawa region, one of the largest undeveloped bauxite deposits in the world and not yet in commercial production. The project holds a mineral resource of roughly 1.1 billion tonnes with ore reserves of about 144 million tonnes, at grades of approximately 51% alumina and about 2% silica. That combination of high alumina and low silica is the reason the deposit gets attention: reactive silica drives caustic soda consumption in the Bayer process, so a low-silica bauxite is worth materially more per tonne to a refiner than the grade alone suggests.

Development is logistics-led — rail and port capacity set the schedule. The deposit sits inland and depends on rail haulage to port, and the company has been taking delivery of rail rolling stock ahead of first shipment. As at August 2026 Minim Martap had not yet shipped commercial bauxite. This is the highest-risk name on the page by some distance: a pre-revenue single-asset developer in a jurisdiction with no existing bauxite export industry, at a market capitalisation an order of magnitude below the producers on this page.
