Perseus' "stretch" target of pouring first gold at Yaoure in December could be met, and the company also expects to meet or beat production forecasts for the first half from its established Edikan and Sissingue operations.

Combined production totalled 68,772 ounces at all-in site costs of US$964/oz, with half-year guidance being 125,500-139,000oz.

Perseus managing director Jeff Quartermaine said in an investor briefing the December quarter should be "as good, if not better" than the September period.

"Notional" cashflow in the September quarter totalled US$43 million.

Quartermaine made the point that depending on how the December quarter goes, Perseus could get to the completion of Yaoure having notionally funded it entirely out of existing treasury and internally generated cash.

Yaoure's development was 85% complete, with $223 million of the $265 million budget committed.

Available cash and bullion on hand at quarter's end totalled $147.4 million, a decrease of $16.2 million relative to June 30.

Perseus' corporate debt remains fully drawn to the facility limit of $150 million, giving a net debt position of $2.6 million.

Shares in Perseus were down 3% to A$1.34 in morning trade, capitalising the miner at $1.6 billion.
