Robex builds output momentum at Guinea's Kiniero gold mine

Canadian developer Robex Resources produced 39,367 ounces of gold in the first quarter of 2026 at its Kiniero mine in Guinea, its first full quarter of output since the operation reached commercial production on 11 February. Of that total, 38,178 ounces were poured on site and 32,306 ounces were sold or provisionally sold, at an average realised price of $4,804 an ounce, according to the company's quarterly update.

From past-producer to new mine

Kiniero sits about 546km from the Guinean capital Conakry and previously operated between 2002 and 2014, producing 418,000 ounces before being placed on care and maintenance. Robex rebuilt the operation at an estimated total investment of $243 million, targeting average production of 139,000 ounces a year over an initial nine-year mine life. The company says construction and commissioning were completed on time and within budget, with the first on-site gold bar, weighing 2.64kg, poured in late 2025.

By quarter-end, Robex held $255 million in cash and bullion, giving it a cushion to keep investing in the mine while gold prices remain elevated. A further 3,288 ounces were shipped in early April, generating an estimated $15.2 million.

Why it matters

Kiniero is Guinea's second new gold mine to start up within three years, part of a broader push by the government to diversify export revenue beyond bauxite and the giant Simandou iron ore project. For Robex, a steady ramp-up reduces the execution risk that weighs on newly built mines in their first months, when mechanical availability and grade control typically determine whether guidance is met.

What happens next

Robex has also been expanding its footprint in West African gold through corporate activity: the company's Guinea neighbour Predictive Discovery, which owns the multi-million-ounce Bankan deposit in the same country, completed a merger process in 2026 that brought the two companies' Guinean assets under common ownership. For Kiniero itself, the near-term focus is holding output near the top end of guidance as the mine moves through its first anniversary of production and the company looks to convert cash generated on site into funding for further regional growth.
