Investor Insight
Metro Mining is uniquely positioned as one of the few pure-play upstream bauxite companies globally listed on any stock exchange. As a direct exposure to the growing aluminum sector, Metro offers investors a unique opportunity to capitalize on the rising global demand driven by traditional industrial applications and emerging sectors such as electrification, battery technologies, and lightweight transportation solutions.
Overview
Metro Mining (ASX:MMI) is a low-cost, high-grade Australian bauxite producer, uniquely positioned as a pure upstream investment in the aluminum supply chain. Metro's flagship asset, the Bauxite Hills Mine in Skardon River, is strategically located 95 km north of Weipa, Queensland, and encompasses a total tenement package of approximately 1,900 square kilometers. As of 31 December 2023, the project boasts an impressive total bauxite resource of 118.7 million tons (Mt) including 83.2 Mt of reserves, featuring high-quality direct shipping ore (DSO) that requires no upgrading.
Following a significant capacity expansion completed in 2024, production at Bauxite Hills Mine is ramping up to achieve sustained throughput exceeding 7 Mt per annum, reinforcing the company’s position as one of the lowest-cost bauxite producers globally. With a further planned capacity increase set for 2025, Metro Mining is well-positioned to exploit continued price strength and robust demand from key Asian markets, particularly China.
Bauxite Hills Mine
The aluminum sector has seen annual growth rates rise from approximately 2 to 3 percent to around 3 to 4 percent due to expanding use in electric vehicles, renewable energy infrastructure, battery manufacturing, and the "lightweighting" of transportation. Recent geopolitical developments, such as reduced bauxite exports from Indonesia, have created supply constraints, driving up bauxite prices significantly. Australian bauxite spot prices reached approximately US$90/DMT in early 2025, up 89 percent from early 2023, which further enhances Metro's revenue potential.
Metro Mining significantly improved its financial position in 2024 by fully repaying junior debt, restructuring senior debt on more favorable terms, and successfully negotiating long-term freight contracts that substantially reduced shipping costs.
Ending 2024 with approximately AU$42 million in cash and trade receivables, the company is positioned for robust financial flexibility and strength. With a simplified and deleveraged balance sheet, Metro is well-equipped to execute its growth strategy and enhance shareholder value.
Metro Mining is led by a seasoned management team with deep expertise in bulk commodities, operational optimization, and corporate strategy, emphasizing sustainable growth and shareholder value creation.

Key Project
Bauxite Hills Mine (Queensland, Australia)
Metro’s flagship asset, the Bauxite Hills Mine, is a low-cost, high-quality DSO operation with total resources of 118.7 Mt, including proven and probable resources of 83.2 Mt. The mine benefits from minimal overburden of just 0.5 meters, short average haul distances of 9 km, and no requirement for blasting, contributing to exceptionally low production costs. Production capacity is set to expand from current levels to approximately 7 million wet metric tonnes (WMT) annually by 2025.
The mine has achieved sustained daily production rates of approximately 30,000 WMT, supported by efficient marine logistics utilizing Capesize vessels and specialized tug and barge systems. Robust off-take agreements are in place with major industry players, including Chalco, EGA, Xinfa Aluminium and Lubei Chemical.
Kaolin Deposit (part of Bauxite Hills)
Metro’s Bauxite Hills property also contains a significant kaolin deposit beneath its bauxite resources. The company is advancing a definitive feasibility study for kaolin extraction, evaluating potential market entry strategies, mine planning and product market testing.
This project represents a potential new revenue stream, with applications spanning ceramics, paper manufacturing, paint and other industrial uses.

Pure-play low-cost producer of high-grade Australian bauxite
Bauxite Investing: Securing Supply Amid Tightening Aluminum Market
Infographic via Metro Mining.
Across North America, Europe and Asia, governments now recognise aluminum as a strategic material critical to 21st-century infrastructure and decarbonsation efforts. The US has included aluminum in its 2023 critical materials list, while the EU has added it under its Critical Raw Materials Act.
Surging demand, fragile supply
Rapidly growing bauxite demand is increasingly colliding with a supply base concentrated in just a handful of producers. Australia, Guinea and China account for roughly 65 percent of global output, underscoring the sector’s vulnerability to regional disruptions. Grand View Research projects an expanding global bauxite market driven by sustained demand from electric vehicles (EVs), lightweight transport and renewable infrastructure.
At the same time, geopolitical turbulence is affecting supply reliability.
Guinea, which has the world’s largest bauxite reserves, recently revoked some 51 mining licences — mostly targeting underperforming or inactive concessions — as part of broader regulatory reform. Even so, exports surged 36 percent year-on-year in H1 2025 to a record 99.8 million tonnes, and are projected to reach nearly 200 million tonnes annually. Chinese demand continues to remain robust, despite ongoing regulatory shakeup in Guinea.
Amid this supply concentration dynamic, geopolitical risk factors are now coming into play, where both investors and companies down the value chain are placing increased emphasis on securing stable supply sources.
While Guinea remains a critical supplier, its shifting regulatory landscape underscores the strategic value of sourcing bauxite from politically stable, low-cost jurisdictions such as Australia, where supply security is far less vulnerable to geopolitical disruption.

Metro Mining: A strategic pure play
Based at Skardon River, 95 kilometres north of Weipa in Queensland Cape York Peninsula, Metro Mining’s (ASX:MMI) flagship Bauxite Hills Mine produces high-grade “Weipa-style” direct shipping ore with minimal processing requirements.
Its operations are streamlined — short haul distances, low strip ratios, no blasting — and logistics are optimised through efficient barge loading facilities and transhipping systems. These efficiencies have allowed Metro to expand production capacity to 7 million tonnes per year while driving down costs.

Over the past four years, Metro has executed a disciplined turnaround strategy — recapitalising, improving operational resilience and securing quality offtake agreements. In Q2 2025 alone, the company delivered record production of 1.7 million wet metric tonnes and a site EBITDA margin of AU$32 per tonne, an impressive improvement from just AU$18 per tonne at the end of 2024. With 80 percent of volumes sold under quarterly contracts, pricing visibility is strong.

Financially, Metro is on solid ground: a market cap of AU$430 million, secured debt of US$56.6 million, cash of AU$28.7 million and no warrants outstanding. The company is fully hedged for 2025 at a rate of 0.63 US$:AU$, further insulating it from currency swings.
Beyond operational and financial metrics, Metro’s ESG credentials are notable. About 30 percent of its workforce is Indigenous, it has injected AU$5.7 million into Indigenous-owned businesses, and it actively supports community development programs across Far North Queensland.
Looking ahead, Metro is targeting an expansion to 8 million tonnes per year by 2026, along with low-capex debottlenecking projects and exploration programs that could extend mine life well beyond the current 16-year reserve and resource profile. With alumina and aluminum demand set to climb in the clean energy and EV sectors, Metro offers investors a rare combination: low-cost operations, secured market access and scalability in a commodity that is only growing in strategic importance.
Investor takeaway
Bauxite may not yet enjoy the same media spotlight as battery metals, but its role in the energy transition is fundamental. Aluminum is the metal that builds the future — light enough for EVs, strong enough for skyscrapers and infinitely recyclable. Metro offers pure-play exposure to this growth story from one of the most reliable supply bases in the world.
For investors seeking a resilient, strategically positioned mining stock with both yield and growth potential, Metro deserves a place on the watchlist — and perhaps in the portfolio.
