"Our aim is getting more units out of the system," Holohan told a quarterly conference call.

"Simple as that."

Resolute's big efforts over the past year at its flagship Syama operation culminated in a major shutdown last quarter.

Availability above 90% is now being targeted.

Resolute produced 81,770oz in the March quarter at all-in sustaining costs of US$1383/oz.

Despite the major Syama shutdown, both numbers were an improvement on the December quarter as nearly 9000oz of gold-in-circuit was recovered.

Holohan said he was surprised at how much gold was recovered from the between the bricks removed from the roaster.

Meanwhile, net debt reduced by $54.1 million to $174.7 million, with asset sales realising the company $43.7 million.

Shares in Resolute were up 6.2% to A34c in Australia. The company is also listed in London.
