Hummingbird Resources PLC (LON:HUM) has started groundwork at Yanfolila in Mali, as construction of the new gold mine moves into its main phase.
First concrete pouring is expected later this month and the project remains on schedule for first gold pour by the end of 2017, the company said.
Dan Betts, chief executive, said that getting the building work started was an important milestone.
First year production is forecast to be 132,000 ounces (oz) with an initial mine life of eight years.
Mali-based Imagri is the contractor. It was the builder of Randgold Resources’ Loulo underground mine and Gounkoto open pit.
