Alara Resources (ASX:AUQ) said production at the copper-gold processing plant at its Al Wash-hi Majaza Copper-Gold Project in Oman is expected to ramp up to at least 85% to 90% of design capacity, from 62% to 65% currently, following the commissioning of two interim tailings filter presses, according to a Thursday Australian bourse filing.

The tailings filter presses are currently operating in semi-automatic mode under the supervision of the original equipment manufacturer's representatives.

The monthly copper-gold concentrate production is projected to increase to between 3,000 and 3,200 dry metric tonnes.

The acquisition of a permanent tailings filter press is in progress, per the filing. This would allow the plant to operate at or near full design capacity.

The project is operated by Al Hadeetha Resources, in which Alara holds a 51% interest.

Alara Resources' shares surged past 31% in recent Thursday trade.
