Despite what its CEO Dan Betts deemed a challenging quarter, Aim-listed Hummingbird Resources delivered an 18% quarter-on-quarter increase in gold production at just under 17 000 oz from the Yanfolila mine, in Mali, in the quarter ended March 31. This while the Kouroussa project, in Guinea, produced 5 868 oz of gold. The newly commissioned mine experienced disrupted operations in January owing to a fire at a fuel depot, with fuel deliveries having resumed later in the month.
