AusQuest (ASX:AQD) said that a stage two reverse circulation drilling program of around 5,000 meters began at its Cangallo porphyry copper-gold discovery in Peru, according to a Thursday ASX filing.

The program is designed to extend the original copper-gold intersections by redirecting drill holes from the original drill pads as well as stepping out to the west, south, and north.

The program is expected to take four to six weeks to complete, and initial assay results are expected to be available within six to eight weeks from the start of drilling.
