AIM-listed Hummingbird Resources’ Yanfolila gold mine in southern Mali poured its first gold from the carbon-in-leach circuit (CIL) on 19 December. Hummingbird is now focused on completing commissioning and ramping up to commercial production, targeting approximately 130 000 oz of gold in the first full year of operations.

Dan Betts, CEO of Hummingbird, commented: “Producing first gold from Yanfolila is Hummingbird’s most significant achievement to date and we have delivered it on time and on budget. I would like to take this opportunity to thank the Hummingbird team, our shareholders, contractors, advisers, the Government of Mali and all Malian stakeholders for their huge commitment and extraordinary efforts on our journey to turn Hummingbird, as a company, and Yanfolila specifically into a gold producer.

“All major elements of the plant are working to specification; including the crushing, milling and detox circuits, with early recoveries from the CIL circuit showing around 95 %, which is excellent in terms of start-up performance.

“Our initial pour was from early low loaded carbon purposefully withdrawn from the circuit to test the elution and electrowinning circuits, which was successful. As a result, carbon loaded to design specification of greater than 2 000 ppm has been drawn from the CIL circuit and is currently undergoing elution ahead of further ongoing production.
Betts said that nearly 2 million man hours had been expended on the project, adding that it had involved the erection of over 1 600 tonnes of structural steel and plant equipment, the installation of over 20 kilometres of piping and the pouring over 4 000 m3 of concrete.

“Looking forward to 2018, Hummingbird is committed to not only delivering name-plate production at Yanfolila but also demonstrating the growth potential of Yanfolila through the continued conversion of already discovered resources, of which there are over 1 million ounces outside the current mine plan, to mineable reserves,” he said.
