In Burkina Faso the Company owns 90 per cent of the Inata Gold Mine. The Inata Gold Mine poured its first gold in December 2009 and produced 72,485 ounces of gold in 2016.

On 22 May 2017, the Company announced that it had completed its agreement to dispose of 40 per cent of the project to Managem, a Moroccan group listed on the Casablanca stock exchange, which will increase upon completion of a bankable feasibility study for a CIL plant at the site, the incurring of expenditures of at least US$10 million, and the enlarging of the ore reserve, to 70 per cent (in the event of an increase of the reserve to 1 million ounce or more) or 60 per cent (if less than 1 million ounces).
