-- South-southwest trending Imwauna Structure is over 2.0 kilometres long, dipping steeply 80-90 degrees west and remains open along strike. -- Previous drilling has located six zones of moderate, south plunging high-grade gold mineralization. -- All six zones remain open to depth. -- Geological setting is a Bonanza Gold, epithermal, low-sulphidation system. -- PIMA studies of drill core indicate an Illite Group alteration assemblage of illite, smectite and quartz with a moderate pH level Ag greater than Au system. -- Zones are typically 1-4 metres wide, hydrothermal and hydraulic brecciated, with vuggy quartz veining present. -- Pyrite content 1%, minor arsenopyrite, traces chalcopyrite, and visible gold does occur. -- Previous work using fluid inclusions suggest source of fluids from south and at depth. -- Recent drilling is providing indications of zone width and thickness increasing with depth.
In addition to the drill program underway at the Imwauna structure, a seven hole program totalling 1852 metres has been completed on the Kela’s Prospect area. The purpose of the program is to locate the previously untested structure and defining its orientation as it appears to be dipping moderately to the east, towards the Imwauna Structure. Low sulphidation epithermal veining was encountered in most holes. Further drilling may be undertaken once assay results are received and the data compiled.

All holes drilled by PNG Gold are collared using HQ triple tube drill tools. A few holes have been reduced to NQ size at depth in the hole in order to continue the hole. Geotechnical measurements such as core recovery, fracturing and veining, rock quality designations (RQD’s), hardness and photographic logging are performed systematically prior to sampling and assaying. The core is logged, samples selected by PNG Gold geologists then systematically sawn in half at the site. The one half core sample is numbered, sealed in a bag and delivered by PNG Gold to its base in Alotau where the samples are palletized and placed in secure storage prior to shipment to ALS Minerals in Townsville, QLD. The other half of the core is retained at the site.
Core samples are dried, crushed and pulverized to 85% passing through a 75 micron mesh. The pulps are assayed for gold and silver using a 50 g split, Fire Assay (FA) and AA finish. Samples grading over 100 ppm Au are subjected to a fire assay with gravimetric finish. Analyses were also carried out for the trace elements As and Pb. Rejects and pulps are stored at the lab for future reference.
