The 10,874oz produced in the first quarter at the Morila operation compares to the guided range of 10,000-11,500oz and forecast second quarter output of 17,000-20,000oz.

Further down the track is a forecast 30,000-35,000oz in the third quarter and 36,000-40,000oz in the fourth reporting period.

The latter means a run rate of more than 140,000oz is expected later this year as the company this quarter moves from mining satellite pits near Morila to the so-called Super Pit (featuring higher grades).

Costs and other details from the first quarter result are due later this month.
