WCB RESOURCES completed channel sampling and mapping at the Umuna Au project in Papua New Guinea and company chief executive Cameron Switzer said it could be critical to unlocking further gold potential.

Preliminary channel sample gold and silver results included 68 metres at 1.96 grams per tonne of gold and 6.08 grams per tonne of silver.

In addition, the company reported 18 metres at 4.07 grams per tonne of gold and 5.56 grams per tonne of silver.

Channel sampling at Kulumalia is part of an ongoing exploration program focussed on the identification and evaluation of surface extensions to the Umuna zone, the main zone of mineralisation on Misima.

This work is in preparation for further drilling, the company said.

“The recognition of the surface Kulumalia extensions could prove to be a critical factor in unlocking further gold potential as not only is this extension defined over a significant distance, but it also brings the opportunity for near surface oxide mineralisation that can be accessed early in any future start up,” Mr Switzer said.

Historical scattered drilling in the area was completed with positive results, he added.

“These channel samples in combination with the mapping data will allow with confidence the accurate interpretation of the mineralised zones to surface for resource modelling.”

“The delineation of surface oxide mineralisation with good grade over significant width is highly encouraging,” Mr Switzer added.

Mapping a channel sampling at the Umuna zone has been focussed on the identification and validation of near surface strike extensions of gold mineralisation.

WCB said mapping to the south east identified the extensions of the Umuna fault zone along with up to three multiple zones of base metal vein stockwork and disseminations developed with gold and silver.

Continuity will be further evaluated with trenching and channel sampling exploration activity, the company said.

Misima Island previously demonstrated a mineral deposit pedigree through the past production of 4 million ounces of gold and 20 million ounces of silver from various operations.

WCB can earn up to 70 per cent in EL1747 Misima from Pan Pacific Copper by spending $9 million within a staged timeframe.

Initially the company obtained 49% interest Gallipoli Exportation PNG, a Pan Pacific Copper subsidiary, with WCB saying it plans to progress towards an additional 21% interest.
