GEOPACIFIC Resources Ltd reports that first results from the island- wide sampling programme at the Woodlark Gold Project have returned encouraging results in the Eastern Region as well as adjacent to the Woodlark King deposit, with several high-grade anomalies identified.

The company said the results will assist in advancing the existing 1.57Moz Au Resource towards Geopacific’s exploration target which has a range of 53.3Mt @ 2g/t Au to 105 Mt@ 1g/t Au for 5Moz Au.

Geopacific managing director, Ron Heeks, said soil sampling over the Eastern Region in the Watou area has delineated a large, high grade, cohesive gold anomaly more than 1.4 kilometres long and open along strike. Grades returned have been up to 6.28g/t Au. Sampling indicates the presence of a linear feature more than 3.8 kilometres long with anomalous gold values greater than 100ppb gold (0.1g/t Au) along its length, trending from the coastline south-west of Watou, through the Watou area towards the north-east and beyond. The anomalism is three times longer than the strike length of the existing deposits at Kulumadau and Busai, where over 1 million ounces of defined Reserves are situated.

Historic exploration in the Watou area includes scattered trenching and drilling, with a best intercept of 16m @ 3.3g/t Au in drilling and 27.4g/t Au in rock chips. Mapping of the Watou area indicates the presence of intrusive lithologies including granodiorite and quartz feldspar porphyries that have a spatial relationship to observed surface gold mineralisation. Some historical alluvial mining in the drainages south of Watou on the Suloga Bay coastline are noted.

Exploration to define the wider extents of the Woodlark goldfield have commenced and the initial results are very encouraging. They will begin to guide us to defining the potential of the larger Woodlark goldfield across our 600 square kilometres of exploration licences,” Mr Heeks said.

“The results from this program are extremely high for soil values and indicate several strong sources of potential new mineralisation in areas with little or no previous exploration. The extent of the anomalism over such broad areas is consistent or greater than those identified over the current pit areas, which currently hold delineated Reserves of more than 1 million ounces.

“Broad spaced geochemistry over areas of outcropping volcanics is ongoing. Infill soil sampling will be used to further delineate the zones prior to drilling. With results this encouraging, we look forward to what other areas may hold.”

Woodlark King

Baseline sampling over and around the Woodlark King deposit area confirmed the presence of gold anomalism over the deposit and also identified new areas of gold anomalism to the south-west and north-east (Figure 1).

The anomalism to the north-east is located in an unexplored area with no historical gold workings and may represent a parallel mineralised system. Anomalous gold values to the south-west of Woodlark King may be influenced by mine spoils associated with a historical prospect referred to as the Golden Pig. Soil sampling results over this area are patchy due to the intermittent presence of thin, post-mineralisation sediment covering the prospective lithology.

Soil sampling program ongoing

An island-wide soil sampling and geological mapping programme over prospective, outcropping volcanic lithologies commenced in the first quarter of 2018 and is approximately 50% complete.

Soil samples are collected at 50 metre centres along lines that are spaced 200 metres apart.

This program represents the first comprehensive, island–wide geochemical assessment of prospective lithologies and is designed to provide a consistent level of base data to guide exploration in testing the true potential of the broader Woodlark goldfield. Sampling commenced on the southern peninsula at Suloga, in the Watou area and surrounding the Woodlark King deposit.

Sampling continues over the remainder of the target areas, with crews also revisiting areas of anomalous gold and copper values to undertake infill sampling and detailed mapping.
