The Mandena mine has been at a standstill since August 28. QMM, Rio Tinto's Malagasy subsidiary specialising in ilmenite mining, officially suspended operations at Mandena, in the Fort-Dauphin (Anosy) region. The direct cause: three weeks of road blockades by local communities demanding enforcement of a court ruling.
A Landmark Court Ruling
On February 18, 2026, the Fort-Dauphin court of first instance ruled that 27 farming families had suffered lasting damage to their land due to flooding caused by the mine's retention dam since 2007. Madagascar's Supreme Court upheld this ruling on August 4, 2026.
The ordered compensation amounts to 9.9 billion ariary, roughly €2 million. Half was due immediately — a deadline QMM reportedly missed. Blockades at Coco Beach, on the road accessing the site, made operations impossible.
Malagasy Ilmenite in the Global Titanium Dioxide Chain
Ilmenite mined at Mandena feeds the global titanium dioxide supply chain — the white pigment used in paints, plastics and cosmetics. The suspension comes in an already fragile context: since June 2026, several local contractors have reported the unilateral termination of their contracts with the mining group.
The economic impact extends well beyond the extractive sector. Fiscal revenues tied to ilmenite exports represent a meaningful income stream for the Malagasy state, which had revised its 2026 growth forecast upward to 6%.
Why It Matters
This case shines a light on the growing tension between major mining companies and local communities in Madagascar — and more broadly across Africa. It raises fundamental questions about benefit-sharing and the environmental accountability of foreign extractors.
The Supreme Court's ruling could set a precedent across the Indian Ocean region, where several mining projects face similar challenges. For Rio Tinto, whose global ESG reputation is already under scrutiny, how this crisis unfolds will be closely watched by institutional investors.
