Strategic Importance
DRI grade product holds significant importance in modern steel manufacturing due to its high purity and role as a feedstock into EAFs which offer a more cost-effective, and more environmentally friendly steel production alternative to traditional blast furnace methods. EAFs require lower capital investment and maintenance; they can be installed and operated with significantly lower upfront costs, using electricity instead of expensive and environmentally harmful coking coal as the primary energy source, and can operate under lower thermal stress, which reduces maintenance frequency and costs over time. The advantages of employing this production method give projects that can deliver DRI grade pellet feed concentrate a substantial market opportunity.
Accordingly, the achievement of DRI product quality test results is a significant milestone for the Zanaga Project, positioning the Company to potentially capitalise on the rising global demand for premium quality, low carbon footprint steel products. The successful results from both hematite and magnetite samples validates the robustness of the Zanaga Project's planned processing approach. The ability to consistently produce high grade DRI pellet feed concentrate, suitable for DRI pellet production to supply EAF steel customers, provides a clear competitive advantage and highlights the Zanaga Project's investment appeal to strategic and financial investors, whilst contributing to sustainable steelmaking and aligning with global efforts to reduce industrial carbon footprints.
Overview of test work and results
Overview of test work and results
During Q2 2025, the Company commissioned and completed a metallurgical laboratory test work programme aimed at determining the ability of the Zanaga Project to produce DRI grade pellet feed concentrate across its full 30 million tonnes per annum ("Mtpa") planned production scale, including both Stage One (12Mtpa) and Stage Two (18Mtpa expansion).
Representative samples of the Zanaga Project resource were assembled from both hematite and magnetite orebody lithologies, required for the Stage One and Stage Two phases of the Zanaga Project respectively.
The primary test work programme was conducted in China, involving comprehensive laboratory analyses, employing magnetic separation and flotation processes. Adjustments to the Zanaga Project's planned flow sheet resulted in the optimisation of process step configuration and, in some cases, replacement of certain processing equipment in the original flow sheet. ZIOC's team of expert technical consultants have guided that there should be no expectation of any significant change to capital and operating costs as a result of the changes to the flow sheet.
