Why Zanaga Iron Ore Is in Focus Today

Zanaga Iron Ore Co. Ltd (LSE:ZIOC) is drawing renewed attention on the FTSE AIM All-Share on 5 November 2026 after confirming that it has completed a 30,000-tonne bulk sampling programme at its flagship iron ore project in the Republic of Congo. The update, released earlier this week, marks the first significant physical activity at the site in more than a decade and is a tangible step towards proving the project can produce premium direct reduced iron, or DRI, grade pellet feed.

Chief executive Martin Knauth described the completion of bulk sampling as a significant milestone and said the company will now progress to metallurgical testing and the subsequent final engineering and design work. For a stock that has spent years being valued as a long-dated option, visible progress on the ground matters. The shares, trading around 2.9p, sit well below the 4p price of the company's May 2026 Equity raise, a gap that has sparked lively debate on investor forums about whether the market is underpricing the asset.

The Bulk Sampling Programme Explained

The bulk sampling programme excavated around 30,000 tonnes of material from the Zanaga deposit. From this, the company will source a 100-tonne composite sample from the hematite zone targeted for the planned Stage One operation of 12 million tonnes per annum. That sample will be used for pilot-scale metallurgical test work to validate Zanaga's revised DRI processing flowsheet.

Economics and Value Enhancement

Zanaga's April 2026 economic update put the net present value of the combined Stage One and Stage Two project at US$4.9 billion, up around 29% on the 2024 feasibility update. Stage One net present value rose to around US$2.54 billion, although estimated Stage One Capital Expenditure increased about 12% to roughly US$2.17 billion. Earlier value enhancement workstreams identified around US$2.2 billion of potential life-of-mine cash cost savings and up to US$352 million of potential capital savings.

Those numbers dwarf the current market value of LSE:ZIOC, which is why the stock attracts value-focused investors. The gap reflects the scale of funding needed to build the project, country risk in the Republic of Congo, and the long timeline to production.

Red Arc Minerals and Project Financing

In February 2026, Zanaga Iron Ore Co. Ltd (LSE:ZIOC) signed a binding term sheet with Red Arc Minerals, a private investment company backed by experienced Mining executives. Under the proposal, Red Arc could invest up to US$25 million into Jumelles, the Subsidiary holding the project, for an initial 20% stake. Zanaga would also receive a 1% net sales Revenue Royalty on all iron ore concentrate sales if the second Tranche closes, although Red Arc can buy back half of that royalty for US$50 million.

On 31 July 2026, Red Arc provided evidence of a letter of intent for potential strategic financing of up to US$500 million for the project and associated infrastructure from a large western government-backed development finance institution. The timetable for finalising transaction documents has been extended as these financing discussions progress, which some investors view as a sign that the deal is growing in scope.

Risks to Consider

Key risks for LSE:ZIOC include further delays to the Red Arc transaction, uncertainty over securing large-scale construction finance, infrastructure requirements including rail and port access, iron ore price Volatility and political and Regulatory Risk in the Republic of Congo. The company's smaller attributable stake after any strategic investment also means shareholders would rely partly on royalty income and minority equity value.

What Investors Are Watching Next

The immediate catalysts for Zanaga Iron Ore Co. Ltd (LSE:ZIOC) are the start and results of pilot-scale metallurgical testing on the 100-tonne composite sample, followed by the launch of detailed engineering and design. Investors will closely monitor any update on finalised Red Arc transaction documents, Shareholder approval and progress on the US$500 million financing letter of intent.

Further out, the target of a final investment decision recommendation in mid-2027 provides the next major valuation checkpoint. Any offtake memorandum with a steelmaker or DRI plant operator would also be a strong signal. With green steel Demand rising, LSE:ZIOC remains one of the most leveraged ways to gain exposure to high-grade iron ore on the FTSE AIM All-Share.
