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 pellet feed concentrate across its full 30Mtpa planned production scale, including both Stage One and Stage Two.
The primary test work programme was conducted in China, involving comprehensive laboratory analyses that employed magnetic separation and flotation processes. The adjustments to the Zanaga Project’s planned process flow sheet are expected to have no significant change to capital and operating costs.
The results demonstrated a DRI specification pellet feed product, and these findings were subsequently confirmed through a separate and independent test work programme, which was completed in the United Kingdom.
