High-Grade Gold Discovery Extends Woodlark Project's Potential
Geopacific Resources has reported exceptional high-grade gold results from trenching at its Little MacKenzie prospect, part of the company's 100%-owned 1.67 million ounce Geopacific Woodlark Gold Project in Papua New Guinea. The findings significantly extend known surface gold mineralisation and come as the company launches a major 30,000-metre drilling campaign.
Impressive Trench Results Showcase Extensive Gold Mineralisation
The trenching program at Little MacKenzie has delivered multiple high-grade gold intercepts that extend surface mineralisation over an impressive 1-kilometre strike length. Standout results include:
- 6 metres at 6.24 g/t gold in trench LMTR25003
- 2 metres at 16.6 g/t gold in trench LMTR25004
- 2 metres at 12.2 g/t gold in trench LMTR25005
- 10 metres at 4.33 g/t gold in trench LMTR25006
- 4 metres at 6.19 g/t gold in trench LMTR25007
These results follow earlier auger sampling that returned multiple zones grading more than 1.0 g/t gold, including individual high-grade gold discovery assays up to 20.0 g/t gold and a peak assay of 63.6 g/t gold at the northernmost auger line.
"These trenching results confirm the strong prospectivity of the broader Woodlark King area, with the high-grade auger results and extensive surface anomalies extending known mineralisation over an approximate 1 km N-S strike extent," said Geopacific CEO James Fox.
Strategic Expansion of the Woodlark King Mining Centre
The Little MacKenzie prospect is located in the under-explored southwest corner of the Geopacific Resources Woodlark Project, within the Woodlark King Mining Centre. This area already contains significant resources, including 1.97 Mt at 1.04 g/t Au for 66 koz Inferred at Wayai Creek, and 5.26 Mt at 0.85 g/t for 142 koz Au Inferred and Indicated at Woodlark King.
The new trenching results have confirmed that mineralisation in the Little MacKenzie area follows a north-south striking ridge line, with gold contained within breccias and quartz-carbonate veining hosted in andesitic volcanics and felsic porphyries—the same Talpos Creek Formation that hosts most of Woodlark Island's gold.
Understanding Epithermal Gold Systems
Geopacific Resources Woodlark Project's gold mineralisation represents a low-sulfidation epithermal system. This type of gold deposit forms relatively near the surface (within 1-2km) where gold is typically deposited by hot, mineral-rich fluids as they cool and interact with surrounding rocks.
In epithermal systems like Woodlark, gold is often found in association with quartz veins, breccias, and stockwork zones. The trenching at Little MacKenzie has revealed these classic epithermal features, with mineralisation hosted in carbonate and quartz veins containing trace amounts of sulfides, surrounded by alteration halos.
Understanding this deposit type is critical for investors, as epithermal gold systems often feature high-grade gold zones that can be economically mined, even at modest scale. Their near-surface nature also typically allows for lower-cost open-pit mining methods.
Ambitious Drilling Program Underway
Geopacific's trenching results are part of a comprehensive exploration strategy that includes a major 30,000-metre RC and diamond drilling campaign now underway across the project. At Little MacKenzie specifically, 26 drill holes are planned for a total of 3,840 metres, comprising 2,960 metres of RC drilling and 880 metres of diamond drilling.
The program is designed to test multiple areas across the property:
- Exploration targets in previously untested areas
- Targets with potential for new mineral resources
- Resource development drilling to expand existing deposits
As of the end of July 2025, the company had completed 43 holes for 3,139 metres, including 2,452 metres of RC pre-collars at various targets and 687 metres of geotechnical diamond drilling at key infrastructure locations.
A second diamond drill rig has now arrived on site to accelerate the exploration program, with first assay results expected in August 2025.
Strong Growth Potential for Woodlark's Resource Base
The trenching results at Little MacKenzie are significant because they indicate strong potential to expand the Geopacific Resources Woodlark Project's current 1.67 million ounce resource base. The extension of surface mineralisation over a 1-kilometre strike length provides multiple new gold targets for the upcoming drilling program.
The company's Woodlark resource currently stands at:
- Measured: 2.25 million tonnes at 3.00 g/t Au for 217,000 ounces
- Indicated: 39.44 million tonnes at 0.98 g/t Au for 1,241,000 ounces
- Inferred: 6.49 million tonnes at 0.98 g/t Au for 205,000 ounces
- Total: 48.28 million tonnes at 1.07 g/t Au for 1,663,000 ounces
With the current drilling program targeting resource expansion, Geopacific appears well-positioned to potentially increase this resource base further.
Why Investors Should Watch Geopacific Resources
Geopacific Resources presents a compelling investment case for several reasons:
-
Resource Growth Potential: The high-grade trenching results at Little MacKenzie demonstrate significant potential to expand the 1.67 million ounce resource base through the current drilling program.
-
Advanced Project Status: The Geopacific Resources Woodlark Project already has a substantial resource and mining lease (ML508) in place, with environmental approvals granted in 2014, reducing development timeline uncertainties.
-
High-Grade Intercepts: The consistent high-grade gold results at Little MacKenzie suggest potential for higher-grade zones that could enhance project economics.
-
Strategic Exploration Approach: The company is pursuing a methodical exploration strategy, using surface sampling to identify drill targets and systematically testing the project's potential.
-
Catalysts Ahead: With assay results from the major drilling program expected beginning in August 2025, investors can anticipate a steady flow of news that could drive value creation.
With gold prices remaining strong and growing investor interest in advanced gold projects in established mining jurisdictions, Geopacific's Woodlark Gold Project appears well-positioned for continued development. Furthermore, recent high-grade copper discovery and high-grade results from other companies in the region demonstrate the mineral potential of this part of the world. The combination of existing resources, high-grade exploration results, and systematic growth strategy makes this a gold story worth following closely in the coming months.
