GOLD output at Mwana Africa’s Freda Rebecca dropped by 14 percent in the third quarter to 31 December despite greater mill throughput low while nickel production also fell 30 percent over the same period.Output for the quarter was 14,298 ounces from 16,555oz in the second quarter while gold recovery rate also slipped to 78 percent from 80 percent in the prior quarter, as the group focused on accumulated ore stockpiles from the two previous quarters.
“Gold recovery rate fell … as the plant had to cope with a low-quality replacement carbon batch which resulted in gold being lost through fine carbon and being passed to tailings. The defective carbon batch has subsequently been replaced,” said the company in a trading update yesterday.
All-in sustaining costs rose by 23 percent to $1,304 per ounce on a quarterly basis. Royalties for the quarter fell 37 percent after government lowered the rates, coupled with lower gold production.
“However, the benefit was countered by an increase in operating costs mainly due to mill shell realignments and clutch replacement costs being realised,” Mwana Africa said.
Nickel in concentration production dropped by 30 percent to 1,383 tonnes from 1,989 tonnes due to fewer tonnes of ore milled, a lower head grade and reduced recoveries. The company also attributed the lower production to ongoing refurbishment.
Sales also dropped by 31 percent quarter-on-quarter, from 2,008 tonnes to 1,395 tonnes as a result of lower production volumes.
“Equipment taken out for the refurbishment exercise, alongside ongoing maintenance reduced resources available for mining development which in turn restricted access to massives. This resulted in a 23 percent drop in mill head grade,” it added.
The low nickel production also increased the cash costs and all-in sustaining costs by 17 percent.
However, the company said the costs are expected to fall in the fourth quarter at the conclusion of the refurbishment.
Chief executive, Kalaa Mpinga said the quarter was “challenging” but remained confident of Mwana’s growth prospects.
“The nickel price decreased by 15 percent during the December quarter to $15,867/tonne (Q2 2015; $18,592/t). Although gold’s price fell to an average of $1,195/oz in the December quarter, the gold price has somewhat recovered in the first month of calendar 2015 and I remain confident in both metals’ longer-term future,” he said.
“At Trojan, the refurbishment programme continued. This, in turn, led to slower development rates than earlier envisaged, affecting access to the massives and their higher grades. With most of the equipment now onsite, the availability issue will be addressed in the next quarter whilst also having a positive impact on costs.”
Mwana Africa also said work on the smelter re-start was ongoing with the delivery of the furnace bricks the expected during fourth quarter of the year.Most key members of the project team were now in place while work on various components of the smelter were ongoing.
