Marengo Mining to begin diamond drilling at Yandera project in Papua New Guinea
Marengo Mining has mobilised a drill rig to begin a planned diamond drilling campaign at the Yandera Copper - Molybdenum - Gold project located in Papua New Guinea.
The company plans to target the Dimbi zone of the Yandera Central Porphyry system.
Marengo intends to commence drilling on or around the 13 September and plans to drill approximately 2,000m, with completion of the ten hole programme planned by the end of 2013.
The drill holes intend to target the mapped mineralised structures, where six holes will jointly test updip projections of elevated copper intercepts in existing drill holes.
Dimbi zone is less focused as an exploration target due to the challenging terrain, when compared with other zones such as Gremi, Imbruminda and Omora, which constitute the Yandera Central Porphyry System.
Marengo has deployed a field mapping programme to understand the geological nature of the Dimbi zone, which includes the nature, extent and orientation of outcropping mineralised structures.
The Dimbi Fault, which is a fundamental north-westerly striking structure, dips at a high angle to the north-east and bounds to the Dimbi zone on the south-west.
This fault has formed a conduit for mineralised fluid flow into the Dimbi zone by a later set of north-east trending faults.
Drill holes are being deployed to test projections of interpreted north-east striking mineralised structures in the hanging wall of the Dimbi Fault, and also at elevated copper intercepts in nearby existing holes.
An extended copper-in-soil geochemical anomaly runs parallel to, and overlies the hanging wall of the Dimbi Fault, which is an important factor in the company's current drilling strategy.
