Geopacific Resources Ltd. has reported encouraging new drilling results from its 100 percent-owned Woodlark Gold Project in Papua New Guinea, including a potential new discovery adjacent to one of the site’s key deposits.
The company is midway through a 30,000-metre drilling campaign designed to expand known gold resources and test multiple new targets across the project area. The program, which combines reverse circulation (RC) and diamond drilling, is central to Geopacific’s aim of increasing Mineral Resources beyond the current 1.67 million ounces.
New find at Kamwak
Among the latest results, Geopacific highlighted a near-surface gold intercept at the Kamwak target, where drilling returned 7 metres at 2.48 grams per tonne (g/t) gold from 21 metres in hole KURC25005.
The company said seven RC drill collars completed across a 600-metre strike length at Kamwak had intersected previously unrecognised mineralisation. The target lies immediately adjacent to the 711,000-ounce Kulumadau gold deposit and shares geological characteristics commonly linked to mineralisation on Woodlark Island.
According to Geopacific, the RC hole was stopped short of its planned depth due to groundwater, but additional drilling is being planned to test the potential of the zone. “Diamond tails and further collar designs (RC & diamond) are being prepared to follow-up on this encouraging intercept, which highlights the potential for a significant new zone of gold mineralisation adjacent to the Kulumadau deposit,” the company said.
Geopacific CEO James Fox described the Kamwak results as a strong sign of the project’s growth potential. “These initial results from Kamwak are highly encouraging and demonstrate the significant growth potential that remains at Woodlark. With our 30,000 metre drill campaign underway, we are confident of delivering further resource growth beyond the current 1.67 Moz base.”
Wider drilling results
The company also reported additional promising intercepts from other targets within the project area. At Busai, drilling returned 2 metres at 11.4 g/t from 9 metres in hole BSRD25002. At Boscalo North, assays showed 4 metres at 2.92 g/t gold from 145 metres in hole KURD25015.
Exploration continues at the Great Northern deposit, where diamond drilling is currently focused on extending RC pre-collars. Once geotechnical drilling is completed, the program will also test broader regional targets.
Geopacific has mobilised an RC rig to the Woodlark King mining area to begin drilling at the Little MacKenzie and Wayai Creek prospects. These follow earlier surface auger and trench sampling that returned positive results, giving the company further confidence in the potential for new discoveries.
Expanding Kulumadau
In addition to exploration drilling, Geopacific is also considering opportunities to expand existing deposits. The company noted that geotechnical drilling at Kulumadau presents an opportunity to extend mineralisation by about 50 metres beyond the current pit design, potentially enlarging the planned mining area.
By the end of August 2025, Geopacific had completed 54 drill collars across five main prospects, totalling 4,567 metres. This included 3,411 metres of RC drilling and 1,156 metres of diamond core drilling.
A second diamond drill rig was mobilised to site in August and is now working on diamond tails to RC pre-collars at the Great Northern deposit.
The overall drill program has been divided into three categories: exploration targets, prospects with potential for new Mineral Resources, and Resource Development drilling. In total, 192 drill collars covering approximately 31,300 metres are planned under the current staged approach.
Looking ahead
With multiple exploration targets now underway and further results pending, Geopacific is positioning the Woodlark Gold Project for potential growth in its resource base. The company emphasised that several of the latest holes remain incomplete, with diamond tails still to be drilled or assays yet to be received.
The identification of mineralisation at Kamwak, alongside strong results from Busai, Boscalo North, and Great Northern, underscores the possibility of extending both the scale and scope of the project.
Geopacific said the combination of new discoveries and extensions to existing deposits supports its strategy of building on the 1.67 million-ounce resource base and advancing Woodlark as a key gold project in Papua New Guinea.
