PC Gold Limited reports promising high-grade gold intersections and extensive visible gold in recent drilling at its Spring Hill Gold Project, setting the stage for a significant resource upgrade.
- High-grade gold intersected in Macau and Hong Kong lodes
- Visible gold observed in multiple drill holes exceeding 30m widths
- 26 drill holes completed for over 7,100m targeting resource upgrade
- Resource definition drilling nearing completion with assays pending
- Drilling to support upcoming Mineral Resource Estimate update and feasibility studies
Strong Drill Results Highlight Spring Hill Potential
PC Gold Limited (ASX – PC2) has provided an important update on its resource definition drilling at the Spring Hill Gold Project in the Northern Territory. The company has intersected high-grade gold mineralisation within the Macau and Hong Kong lodes, confirming the strength of the deposit beneath the planned open pit. Notably, extensive visible gold was observed in five drill holes, with mineralised zones extending over 30 metres downhole, a promising indicator of both grade and continuity.
The recent drilling campaign, which has completed 26 holes totalling 7,137 metres, focused on upgrading confidence in the inferred portion of the Mineral Resource Estimate (MRE) and exploring elevated grade zones. Material assay results include standout intersections such as 2.8 metres at 15.21 grams per tonne gold from just 1.7 metres downhole, including a spectacular 0.3 metres at 124.12 grams per tonne, underscoring the potential for high-grade shoots within the system.
Advancing Towards a Resource Upgrade
With the resource definition drilling program nearing completion, PC Gold is preparing to incorporate these results into an updated Mineral Resource Estimate. The presence of visible gold in multiple holes, both inside and outside the current resource envelope, suggests the possibility of expanding the resource footprint. The company anticipates converting approximately 300 metres of strike length from inferred to indicated classification, a critical step towards defining mineable reserves.
Executive Chair Ashley Pattison expressed optimism about the discoveries, highlighting a new high-grade zone at Macau and near-surface visible gold at Hong Kong, both north of the current pit shell. He noted that the drilling success exceeded expectations and reinforced confidence in the continuity and scale of the Spring Hill mineralised system.
Ongoing Drilling and Next Steps
PC Gold continues to await assay results for approximately 5,100 samples, including infill drilling at the Macau Extension and additional resource definition holes. The company is also transitioning diamond drilling towards metallurgical and geotechnical studies, essential for advancing feasibility work. Reverse circulation drilling is set to resume in early February 2026, targeting further extensional programs at Macau Extension, Lasagne lode, and northern targets.
The Spring Hill Project benefits from granted mineral leases and environmental approvals for open-pit mining, positioning PC Gold to move efficiently through development milestones. The dual-stream strategy of upgrading resource confidence while aggressively exploring extensions aims to enhance both the quality and scale of the resource base.
Context and Historical Significance
Spring Hill is situated within the Pine Creek goldfield, a historically significant gold-producing region. The deposit hosts mineralisation within the Mount Bonnie Formation, controlled by structural features such as anticlines and shear zones. Previous exploration and mining dating back to the late 19th century have laid the groundwork for current activities, with modern drilling and assay techniques now unlocking new potential.
PC Gold’s use of advanced photon assay methods and rigorous quality control ensures reliable assay data, critical for accurate resource modelling. The company’s comprehensive approach includes parallel progress on mining, metallurgy, infrastructure, and permitting to streamline the path to production.
Bottom Line?
As assay results come in and resource modelling advances, PC Gold’s Spring Hill project could soon redefine its gold resource potential, attracting closer market attention.
Questions in the middle?
- How will pending assay results impact the upcoming Mineral Resource Estimate?
- What are the timelines and expected outcomes for the metallurgical and geotechnical studies?
- Could the newly identified high-grade zones materially change the mine plan or production profile?
