Skylark Minerals (ASX:SKM) completed a field exploration program at its Simon copper project in Queensland, with peak rock chip results of 551 parts per million copper and 468 ppm copper, according to a Friday Australian bourse filing.

Field observations confirmed the presence of silica-iron oxide alteration, fault breccias, and buck quartz veining across a corridor along the McNamara fault, and in two satellite zones.

A follow-up fieldwork is planned for later in the year.
