  QUEBEC CITY, Dec. 21, 2025 (GLOBE NEWSWIRE) -- West African gold producer and developer Robex Resources Inc (“Robex” or the “Company”) (ASX: RXR | TSX-V: RBX) is pleased to report it has poured first gold on schedule and within budget at its Kiniéro Gold Project (“Kiniéro”) in Guinea, West Africa.

Robex’s Managing Director and Chief Executive Officer Matthew Wilcox said:

“This is a major milestone for Robex, and every member of our team should be proud of what we have accomplished together at Kiniéro. Completing construction and commencing gold production is the culmination of 17 months of dedication and hard work, delivered safely and responsibly with nearly 5 million hours worked without a lost time injury.

Pouring first gold at Kiniéro reflects the calibre of our people, the strength of our execution and is the sixth successful build in the last 15 years by this construction team, all on time and on budget. This exceptional track record, combined with recent Guinea construction experience, gives us absolute confidence that this is the best team in the industry right now to bring Bankan into production and deliver another world-class West African gold project.

We are looking forward to completing our merger with Predictive, and the combined company is positioned to become West Africa’s next mid-tier gold producer and establish a tier-1 gold mining hub in Guinea.”
