Geopacific sets lofty exploration target in PNG
Geopacific Resources has set itself an ambitious exploration target at the Woodlark Gold Project in PNG that already contains 1.57m ounces of gold.
The company says it is now targeting a resource range of between 53.3Mt @ 2g/t gold and 105 Mt@ 1g/t gold for a possible 5M ounces of gold.
Whilst exploration targets are conceptual in nature and the final outcome is never certain, the new exploration target range represents a lofty goal and provides some insight into management’s confidence in the deposit.
Having just banked $10m from an institutional share placement, the company is hot to trot and looking to advance its current global mineral resource estimate of 47 million tonnes grading 1.04g/t gold.
Geopacific delivered an ore reserve exceeding 1 million ounces earlier this year to underwrite its proposed gold mining operation on Woodlark Island.
Geopacific Managing Director Ron Heeks said: “We met expectations with the release of the Pre-Feasibility Study, which supports the development of Woodlark as a robust, stand-alone project capable of delivering over 100,000 ounces per annum over 10 years. The DFS is moving forward and will further enhance the project economics.”
“The time is now right to commence exploration to show that the larger goldfield will offer more resources.”
“Work has begun at the promising Great Northern area which sits on a structural corridor that’s evident in geophysics, has surface geochemistry and limited drilling that produced results of up to 20m @ 4.39g/t Au.”
“Typically, epithermal orebodies occur in clusters around a central, deeper mineralising source. The mineralisation gets to surface through corridors of weakness caused by faulting in the overlying rocks. Geophysics has allowed us to identify several corridors that are known to be mineralised but have not been fully explored.”
The priority target areas lie between the major Busai deposit and the larger Kulumadau deposit, about 5km to the northwest in a region that remains virtually undrilled due to the presence of masking limestone rocks.
There is significant exploration potential within known mineralised corridors at Woodlark, with many drill targets substantiated with existing geochemical sampling, trenching, historical drilling and favourable coincident geophysical anomalies.
First cab off the rank is the so-called “Great Northern” area, located about 1km northeast of Kulumadau, where historical drilling returned exceptional intersections including 20 metres grading 4.39g/t gold, 18m @ 4.40g/t gold and 26m @ 2.06g/t gold.
The Great Northern prospect lies near the intersection of major northwest and northeast striking structures, with coincident aeromagnetic lows.
According to the company, the mineralisation at the Great Northern propsect has a very similar geological signature to the nearby Kulumadau ore reserve of 548,000 gold ounces.
Geopacific will also review all historical surface geochemical results covering the sought-after host volcanics and complete systematic reconnaissance and geological mapping to evaluate the gold potential of the Woodlark project.
Additionally, a major program of surface soil sampling, geological mapping and sampling is now underway across more than 600 square kilometres of exploration licences.
According to the company, this will be the first island-wide comprehensive reconnaissance exploration program ever conducted and is likely to provide invaluable data on the entire outcropping geological terrane.
Regionally the Woodlark area surrounds remain largely unexplored using modern exploration methods and have a long history of gold production and proven gold endowment via significant artisanal workings.
The recent successful $10m placement represents a strong mandate from Geopacific shareholders for the company to embark on its robust exploration program at Woodlark to increase the resource and reserve inventory at the project.
