This week, Astana is hosting two very different conversations about Kazakhstan’s mining future.
In the official corridors, government delegations, US officials, and ministers from across Central Asia are gathered for high-level discussions. Grand statements are being made. Frameworks are being signed. Photographs are being taken.
On the other side of the world in a brick-walled London dining room — a rather different conversation is taking place. A small group of private investors is gathered around a screen, listening to a junior mining CEO explain, with disarming candour, exactly how he plans to turn a copper deposit in Kazakhstan into a billion-dollar producing mine. Without debt. Without dilution. And without losing sleep over capex blowouts.
These two conversations are not separate. They are, in fact, the same conversation — just conducted at different altitudes.
The Ground-Level Reality of Kazakhstan Mining Finance
East Star Resources CEO Alex Walker presented to investors with the kind of frankness that rarely makes it into official mining forums. His central message: the Verkhuba copper deposit in Kazakhstan is now funded to production, with Chinese EPCM powerhouse Xinhai taking 70% in exchange for carrying all development costs — an estimated US$65 million — to first copper.
East Star retains 30%, fully carried, with no debt obligation. Xinhai gains majority only when it has delivered US$50 million worth of equipment to site. Until that moment, East Star holds control.
“You do not get majority until you have sunk way more money into this,” Walker tells his audience.
It is a deal structure worth understanding carefully, because it illuminates something important about how junior miners are actually navigating the Kazakhstan opportunity in 2026 — and it is a long way from the headline-grabbing announcements coming out of this week’s official forums.
The Xinhai model — a Chinese EPCM contractor taking equity in exchange for funded development — is not new. But its scale and pace are accelerating. Xinhai now claims over 2,500 projects delivered globally, with more than US$42 million committed to ASX and LSE-listed companies for feasibility and construction in 2025 alone. They manufacture their own processing equipment, manage their own supply chains, and have demonstrated the ability to build a 1.5 million tonne per annum processing plant in Kazakhstan in under twelve months.
Walker is characteristically direct about the implications: “I visited their factory in Yantai. They make everything — the rubber liners that go in your crushing plants. That means you are not reliant on where you sit in a queue for your equipment provider. You manage your entire supply chain.” When Xinhai told him they thought they could deliver Verkhuba within a compressed timeline, he said, he believed them.
For a junior miner navigating the gap between resource and production — the graveyard of so many promising projects — this kind of vertically integrated partner is genuinely transformational. Walker is blunt about which risks he had effectively eliminated: financing, capex blowouts, and timing. Three of the five classic killers of junior development projects, struck off in a single deal.
The Copper Market Context Nobody Is Ignoring
Walker touched on the macro backdrop, referencing a conversation with senior Goldman Sachs mining analysts about the copper deficit forming in the rest-of-world, non-US market. The figures are striking. Goldman Sachs now projects a deficit of over 640,000 tonnes in ex-US copper markets in 2026 — a number revised sharply upward from a prior estimate of just 60,000 tonnes, driven largely by US front-loading of copper imports ahead of potential tariffs. J.P. Morgan adds a 330,000-tonne deficit projection of its own, while even the historically conservative International Copper Study Group has swung from forecasting a 209,000-tonne surplus in late 2025 to a 150,000-tonne deficit by May 2026.
The convergence of major institutional forecasters on a significant 2026 deficit is the backdrop against which Walker’s geopolitical point lands hardest. Copper from the DRC loaded onto a ship can be diverted mid-voyage to capture a premium on the COMEX in New York. Copper that travels by rail from Kazakhstan cannot. Its destination is fixed. In a world where tariffs and trade route disruption are rewriting commodity flows in real time, Kazakhstan’s landlocked geography – once a liability – is becoming a structural advantage for certain end markets, particularly China. The supply cannot be diverted. It simply arrives.
The Questions Investors Are Actually Asking
The sharpest exchanges of the meeting came during questions. One investor raised the spectre familiar to anyone who has backed a junior miner in a joint venture with a larger partner: what stops the big partner from simply putting the project on ice when it suits them?
Walker’s answer was layered. First, the deal structure itself: Xinhai only achieves majority when equipment worth US$50 million has been delivered to site. If they walk away before that, East Star keeps its majority and a significant amount of delivered capital. “They’d be selling US$50 million worth of equipment and still getting a good return on capital,” he noted. “So we’ll figure out how to build it ourselves.”
Second, he made a pointed commercial observation: Xinhai wants East Star to be their business development partner in Kazakhstan, bringing them more deals. Betraying a partner publicly would destroy that franchise. “The first group they screw over — that business model is shut,” he said. “That’s why I don’t think they’d do it.”
A second question probed the structure of East Star’s 30% retained interest more sharply: does the company actually own 30% of the project, or is it simply entitled to 30% of the copper? And crucially, who controls the surplus capital once the mine is producing?
Walker confirmed that East Star owns 30% of the project entity, with marketing rights for approximately 30% of production. On dividend distribution, he was direct: under the shareholders’ agreement with Xinhai, dividend policy is a reserved matter requiring mutual agreement — the majority shareholder cannot unilaterally determine how cash is deployed. “Dividend distribution is one of those matters that needs a vote from both sides,” he said. Whether the cash ultimately flows back to shareholders or is redeployed into new projects — perhaps towards building a 300,000-ounce-per-year gold mine with Endeavour — is a question for later. The structural protection, he argued, is real.
It was, collectively, the answer of someone who has read enough JV agreements to know exactly where the traps are.
AI and the New Exploration Toolkit
One detail from the evening deserves particular attention, and it speaks to how the competitive landscape for junior miners in Kazakhstan is changing.
East Star’s porphyry gold exploration programme — the Snowy and Piket licences on the Balkash-Ili magmatic arc — was initially funded through a grant from the BHP Xplor programme, which Walker described as “a highly competitive programme: 600 applicants, 6 accepted.” The programme is explicitly oriented around applying advanced analytical techniques — including AI-driven target generation — to early-stage exploration. East Star’s selection is a mark of technical credibility that carries weight with institutional investors.
The broader context matters here. Kazakhstan’s government has been investing heavily in the digitalisation of its geological archive — over 97% of primary geological information, approximately 250 terabytes of data, has now been scanned and consolidated into a unified system. An AI-powered platform has been developed to automatically process this archive, extract coordinates, and generate subsurface geological models. Officials describe the technology as significantly reducing data processing time and improving the quality of exploration decisions.
For companies like East Star, operating across some of Kazakhstan’s most prospective but underexplored belts, this convergence of digitised state geological data and AI-assisted targeting represents a genuine step-change in the speed and cost of identifying drill-ready targets. The question of where the next Nikolskoye or Verkhuba might be hiding is increasingly one that algorithms, not just geologists, are helping to answer.
The Regulatory Picture: Nuance Required
One of the most interesting questions of the meeting came from an investor who had been tracking changes to Kazakhstan’s mining regulatory framework. The question concerned a reported increase in the threshold for mandatory government approval of ownership changes in mining companies, and the role of the national mining company Tau-Ken Samruk in new joint ventures.
The regulatory picture here is genuinely nuanced, and worth examining carefully.
Kazakhstan’s December 2025 amendments to the Subsoil and Subsoil Use Code were primarily aimed at digitalisation, transparency, and strengthening strategic investor incentives. Separately, amendments signed by President Tokayev also tightened state control in the uranium sector specifically, raising certain transfer thresholds and granting Kazatomprom priority rights over uranium exploration licences.
As for Tau-Ken Samruk — the state’s national mining company and a subsidiary of the sovereign wealth fund Samruk-Kazyna — Chambers and Partners’ 2026 Kazakhstan Mining guide notes that the government is actively seeking to restore Tau-Ken Samruk’s priority rights for obtaining exploration and mining licences for critical minerals, a right that had previously been removed as part of earlier liberalisation efforts. “We expect this priority right to be restored in 2026,” the guide notes, describing it as a deliberate effort to increase the state’s foothold in the early stages of the critical minerals supply chain.
The direction of travel is clear, even if the precise mechanics are still being finalised: Kazakhstan is simultaneously offering incentives to attract international capital and tightening state participation rights in the assets that matter most. For investors in junior miners operating here, this duality is not a contradiction — it is the operating environment. Understanding it, and structuring agreements, accordingly, is the price of entry.
This is precisely the kind of regulatory intelligence that MINEX Eurasia Forum — convening in London on 30 November as part of London Mining Week — exists to provide. The forum brings together mining investors, operators, legal practitioners, and government representatives from across the region to examine exactly these dynamics: where is capital coming from, on what terms, and under what regulatory conditions?
The Endeavour JV: A Different Model, Same Logic
East Star’s joint venture with Endeavour Mining – a US$25 million exploration programme with one of the world’s top ten gold producers – follows a different but structurally similar logic. Endeavour funds exploration through to pre-feasibility study, earning up to 80% along the way. East Star manages the JV until Endeavour reaches 51% and is carried through to PFS completion.
Again: no dilution beyond agreed thresholds, no unilateral majority until capital milestones are met, and a world-class operator bearing the exploration and development risk.
Walker’s reference point is Independence Group in Western Australia — a company that held a minority in what became the Tropicana gold project with AngloGold, eventually building that stake into hundreds of millions of dollars of annual cash flow. The analogy is instructive: the value is not in owning the whole mine. It is in owning the right percentage of the right mine, with the right partner, under the right agreement.
Walker put it simply: “If we have 20% of something that Endeavour is building, even with financing, that’s a billion-dollar company for just East’s percentage. That’s something I’m really excited to maintain.”
This philosophy is increasingly evident among the better-managed junior miners operating in Central Asia. The era of the go-it-alone junior – raising capital dilutively on the back of exploration results, lurching from drill hole to drill hole – is giving way to something more sophisticated: structured, partner-funded development with clear milestone-based governance.
MINEX Asia and the Longer Arc
For those who follow the MINEX forum series closely, none of this comes as a surprise. Over more than a decade, MINEX Eurasia events in London have documented and debated the evolution of mining investment in Central Asia and the Caucasus — the shift from Soviet-era brownfield rehabilitation to greenfield discovery, the growing role of Chinese EPCM capital, the fitful but real improvement in regulatory environments, and the persistent challenge of converting geological endowment into investable projects.
What is new in 2026 is the intensity of the moment. The critical minerals agenda — driven by the energy transition, by great power competition over supply chains, and by the explicit industrial policy of both the EU and the US — has focused international attention on Kazakhstan, Kyrgyzstan, Uzbekistan, and their neighbours in a way that was not true even three years ago.
The question that MINEX Asia 2026, convening in Ankara this month, is already pressing — and that MINEX Eurasia Forum will continue to examine in London in November — is whether this intensified international attention translates into genuinely diversified investment, or whether the structural realities of Kazakhstani mining (Chinese EPCM dominance, evolving state participation requirements, infrastructure constraints) mean that the beneficiaries of the critical minerals boom will ultimately be narrower than the official narrative suggests.
The Real Work
Back in that London dining room, the questions kept coming. Minority shareholder protection. Dividend policy. The role of assay labs on site. The timeline to production. Each one answered with the same register: direct, detailed, and unspun.
It was a window into the real sophistication now required to operate as a junior miner in Kazakhstan. The geology is compelling. The copper market backdrop is as strong as it has been in years. Chinese EPCM capital is available, at scale, on terms that can work for a well-advised junior. The regulatory environment, for all its complexity, is navigable.
But the deals that will create value – the ones that will turn exploration licences into producing mines and producing mines into returns for investors — will be won or lost on the quality of the agreements, the rigour of the governance structures, and the acuity of the people sitting across the table.
Ministers may gather for the photographs, but the real work happens away from the cameras.
