New Macau Link Zone Discovery Opens Questions on Spring Hill’s Mining Future
PC Gold has confirmed a new high-grade gold discovery at its Spring Hill Project, with assays revealing impressive grades over significant widths in the Macau Link Zone. This breakthrough could reshape the mine’s future resource and development plans.
- Five diamond drill holes confirm continuity of Macau Link Zone over 225m strike
- Notable intersections include 4.5m at 28.36 g/t Au and 25m at 36.83 g/t Au
- Zone remains open in all directions, extending 300m down dip
- Upcoming eight-hole drilling program to test extensions and define scale
- Discovery supports potential early underground mining and pit wall access
A New High-Grade Discovery Emerges at Spring Hill
PC Gold Limited (ASX: PC2) has delivered a compelling update from its Spring Hill Gold Project in the Northern Territory, unveiling high-grade assay results that validate the newly identified Macau Link Zone. The company’s recent diamond drilling campaign has intersected visible gold and consistent mineralisation over a strike length of approximately 225 metres, confirming the continuity of this exciting new domain.
Among the standout results, hole SDH25-030 returned an impressive 4.5 metres grading 28.36 grams per tonne (g/t) gold from 328 metres depth, while SDH25-028, a previously reported discovery hole, yielded a remarkable 25 metres at 36.83 g/t gold, including a 2-metre section at an extraordinary 444.3 g/t. These grades underscore the zone’s potential to host economically significant high-grade mineralisation.
Expanding the Resource Footprint
The Macau Link Zone is currently modelled as a roughly 15-metre-wide structure extending about 300 metres down dip, yet remains open in all directions. This openness suggests considerable upside potential as further drilling is planned to test both up and down dip extensions. PC Gold is set to commence an eight-hole diamond drilling program designed to refine the zone’s scale and continuity, with drill pads already prepared and the rig mobilising imminently.
Executive Chairman Ashley Pattison highlighted the significance of the discovery, noting that the Macau Link Zone could be accessed early in the mine life through the proposed extension of the historical underground adit. There is also potential for surface access via pit wall push-back, which would enhance mining flexibility and economics.
Strategic Implications for Spring Hill
The Macau and Hong Kong lodes together account for approximately 86% of the current Mineral Resource Estimate (MRE) ounces at Spring Hill. Until now, these zones have been primarily evaluated for bulk tonnage open pit mining, followed by underground operations. The emergence of the Macau Link Zone as a distinct, high-grade domain offers a new strategic avenue for PC Gold to potentially accelerate underground development and improve project economics.
PC Gold is advancing geological wireframing and resource modelling in consultation with independent technical consultants to incorporate the Macau Link Zone into the upcoming MRE update. Concurrently, the company is progressing feasibility studies, including underground infill drilling from the existing adit, with design and development works scheduled for the June quarter of 2026.
Looking Ahead
With assays pending from some recent holes and the zone still open for expansion, PC Gold’s discovery at Macau Link injects fresh momentum into the Spring Hill project. The company’s dual focus on resource growth and feasibility advancement positions it well to unlock the full potential of this high-grade gold system.
Bottom Line?
PC Gold’s Macau Link Zone discovery could redefine Spring Hill’s resource profile and mining strategy, with further drilling poised to unlock its full potential.
Questions in the middle?
- How will the Macau Link Zone impact the overall Mineral Resource Estimate and mine plan?
- What are the timelines and capital requirements for integrating this new domain into production?
- Could the Macau Link Zone extend closer to surface, enabling earlier open pit extraction?
