Diamond Drill Hits 0.7m at 459 g/t Gold at Spring Hill’s Lasagne Target

A New Benchmark in Grade at Spring Hill

PC Gold Limited (ASX, PC2) has delivered a breakthrough in its 2025 exploration campaign at the Spring Hill Gold Project in the Northern Territory. The company announced assay results from diamond drill hole SDH25-009 at the Lasagne Target, revealing an extraordinary narrow vein intersection grading 0.7 metres at 459.08 grams per tonne gold (g/t Au). This includes an even richer 0.5 metres at 606.72 g/t Au, marking the highest grade interval ever recorded at Spring Hill.

Visible gold was noted multiple times in the core, underscoring the exceptional nature of this find. Positioned approximately 200 metres north along strike from the existing Mineral Resource Estimate (MRE), this discovery hints at untapped high-grade mineralisation extending beyond previously defined boundaries.

Implications for Resource Growth and Development

The Lasagne Target, historically underexplored relative to the main resource zones, is now emerging as a key focus area for PC Gold’s growth strategy. The company has completed nearly 5,800 metres of drilling targeting this zone, with SDH25-009 standing out as a flagship result. The proximity of this hole to the Middle and Main zones of the MRE suggests potential for incorporating new high-grade domains into future resource updates.

Spring Hill’s existing JORC-compliant resource stands at 25.6 million tonnes at 1.0 g/t Au, but these recent results could materially enhance the grade profile and overall inventory. The project benefits from granted mining leases and environmental approvals, positioning PC Gold to advance swiftly toward production.

Looking Ahead, Follow-Up Drilling and Exploration

Encouraged by these findings, PC Gold plans to commence follow-up drilling before Christmas, focusing on both the narrow vein high-grade intersections at Lasagne and the broader Macau Extended Target. The company’s Executive Chair, Ashley Pattison, highlighted the significance of this early success, emphasizing the untapped potential along strike and the excitement around upcoming results.

While assays for additional diamond holes from the Phase 1 campaign are still pending, the current data reinforce a compelling narrative of resource growth and exploration upside at Spring Hill. The technical team is also undertaking further interpretation work to refine targeting and resource modelling.

Historical Context and Technical Rigor

Spring Hill has a rich mining history dating back to the late 19th century, with over 20,000 ounces historically extracted from oxide zones. Modern exploration leverages advanced drilling techniques, including HQ3 diamond core and state-of-the-art photon assays, to accurately capture coarse gold mineralisation. Quality control and data verification protocols meet industry best practices, ensuring confidence in reported results.

This latest announcement builds on prior releases earlier in November and October, reinforcing PC Gold’s methodical approach to unlocking value from this promising gold system within the Pine Creek Orogen.
