Spring Hill Main Zone Extended by 80m with 14.9m at 3.84 g/t Gold Intercept
PC Gold has extended the Main Zone strike at its Spring Hill Gold Project by 80 metres south, revealing high-grade gold mineralisation within the existing open pit footprint. This discovery could significantly enhance the project’s resource base and economics as drilling continues.
- 14.9m @ 3.84 g/t Au intercept including 0.98m @ 30.6 g/t Au
- Main Zone strike extended 80m south beyond previous resource boundary
- Up to 500m additional southern strike potential identified
- 7,800m Phase 1 drilling program underway targeting extensions
- New mineralisation lies within current pit optimisation shell, improving open pit inventory
Extending the Known Gold Territory
PC Gold Limited (ASX: PC2) has announced a significant breakthrough at its flagship Spring Hill Gold Project in the Northern Territory, with extensional drilling revealing an 80-metre southern strike extension of the Main Zone. The highlight intercept from drill hole SDH25-026 returned 14.9 metres grading 3.84 grams per tonne (g/t) gold, including a high-grade 0.98-metre section at 30.6 g/t Au. This discovery lies within the existing open pit footprint, previously modelled as waste due to lack of drilling, indicating immediate potential to boost mineable inventory.
Geological Reinterpretation Unlocks New Potential
The company’s technical team has reinterpreted the stratigraphy and structural controls at Spring Hill, suggesting the Main Zone plunges southwards parallel to the nearby Hong Kong Lode. This reinterpretation points to up to 500 metres of additional strike potential to the south, most of which remains largely untested. Importantly, over 200 metres of this extension lies within the current pit optimisation shell, offering a compelling opportunity to expand resources without major changes to the existing mine plan.
Ongoing Drilling and Visible Gold Confirm Continuity
PC Gold has commenced a 7,800-metre Phase 1 drilling program comprising 18 holes targeting the southern extension and a newly identified eastern sheeted vein zone. Seven holes have been completed so far, with assays expected in early Q2 2026. Visual identification of coarse visible gold in follow-up drill holes MS-010 and MS-011, located 40 metres along strike and down plunge from SDH25-026, confirms the continuity and plunging nature of the mineralisation. This visible gold is associated with quartz-carbonate-chlorite breccias and sheeted veins containing pyrite and arsenopyrite, hallmark indicators of high-grade gold mineralisation at Spring Hill.
Strategic Implications for Project Economics
Executive Chairman Ashley Pattison emphasised the significance of extending the Main Zone within the highest-grade area of the resource. Bringing additional mineralisation into the existing pit shell could reduce the strip ratio and increase contained gold in the open pit inventory, directly enhancing project economics. The proximity of the Main Zone extension to the Hong Kong Lode also presents opportunities to increase operational scale and improve mining efficiencies. Looking further ahead, the southern extension may offer attractive underground mining targets, potentially increasing ounces per vertical metre and lowering costs when underground operations commence.
Advancing Towards Production
PC Gold is advancing Spring Hill through a dual-stream strategy of infill drilling to upgrade resource confidence and aggressive extensional exploration to grow the resource inventory. Alongside drilling, the company is progressing geotechnical studies and pre-feasibility work to streamline the path toward production. With environmental approvals in place and granted mining leases, Spring Hill is positioned for a swift transition from exploration to development.
Bottom Line?
As PC Gold’s drilling continues to unlock new high-grade extensions at Spring Hill, the project’s economic outlook brightens, but investors await assay results and feasibility studies to confirm the full impact.
Questions in the middle?
- Will assay results from the remaining Phase 1 drill holes confirm consistent high-grade mineralisation?
- How will the southern extension impact the overall Mineral Resource Estimate and mine plan?
- What are the timelines and capital requirements for transitioning from exploration to production at Spring Hill?
