Marengo Begins Diamond Drilling in Papua New Guinea Prospect

28 September 2009

Copper explorer Marengo Mining has started diamond drilling work at the Kombruku prospect in Papua New Guinea.

The Kombruku prospect, which is part of its Yandera copper-molybdenum-gold project, was discovered earlier this year.

It contains copper mineralisation, with certain outcropping samples featuring large concentrations of copper sulphides that grade up to 36.9% Cu.

Two diamond drilling rigs are now being used at Kombruku and are testing major targets identified by a ground geophysics programme.

Five drill holes have been selected and extra holes will be added as the programme advances.

Earlier this year, mapping and surface sampling was carried out at Kombruku, which confirmed the prospect encompasses an 8km2 area.

The discovery at Kombruku opens up a new exploration front for Marengo beyond the Yandera Central Porphyry, which is the focus of the firm’s current definitive feasibility study, Marengo said.
