PC Gold has reported high-grade gold intercepts extending the Main Zone at Spring Hill by 120 metres south, with mineralisation now found within the existing pit shell and drilling ramping up to accelerate resource growth ahead of a June update.
- Main Zone extended 120m south beyond current resource
- High-grade intercepts within existing pit optimisation shell
- Three rigs mobilised to increase drilling capacity
- Updated Mineral Resource Estimate due June 2026
- Mineralisation remains open along strike and down plunge
Main Zone South Extension Delivers High-Grade Gold
PC Gold Limited (ASX:PC2) continues to push the boundaries of its Spring Hill Gold Project with fresh drilling results that extend the high-grade Main Zone mineralisation approximately 120 metres south beyond the existing Mineral Resource Estimate (MRE). The latest assays reveal multiple significant intercepts, including standout hits such as 10.0 metres at 4.51 g/t Au from 161 metres and a blistering 1.5 metres at 30.44 g/t Au from 237 metres in hole MS-006, all within the current pit optimisation shell. This discovery adds a new dimension to the project’s resource potential, as mineralisation previously classified as waste in the pit wall is now being reclassified as ore-bearing.
Importantly, these intercepts occur in areas with limited prior drilling, highlighting the opportunity to delineate additional mineralisation within the existing open pit and underground development envelope. The mineralisation remains open both along strike and down plunge, underscoring the potential for further extensions beyond the current footprint.
These findings build on PC Gold’s recent momentum at Spring Hill, where previous drilling had already extended the Main Zone strike by 80 to 120 metres south, confirming a consistent trend of resource growth beyond the initial envelope. The company’s aggressive exploration strategy is evident as it now operates three rigs onsite, including two diamond rigs and a reverse circulation (RC) rig expected by mid to late May, aimed at accelerating resource definition and expansion efforts. The bulk fuel supply is secured to support this ramp-up in drilling activity.
Resource Growth Within Existing Development Envelope
Executive Chairman Ashley Pattison emphasised the significance of these results, stating that the high-grade mineralisation remains open and continues to expand beyond the current resource. He highlighted the intersection of multiple mineralised zones within the existing pit shell, areas that were previously considered waste, potentially increasing both tonnage and grade in the upcoming resource update.
“With a third rig now mobilised to site, we are well positioned to accelerate resource growth and project definition,” Pattison said. The company plans ongoing drilling on both the Link and Main zones, with results pending for in-fill drilling on the Link zone and a focus on targeting additional Link-style mineralisation across the project.
Upcoming Resource Update and Development Readiness
PC Gold has engaged Cube Consulting to continue resource modelling, with an updated Mineral Resource Estimate expected in June 2026. This update will incorporate the latest drilling results and is anticipated to refine the resource inventory further, potentially enhancing the project’s economic profile.
The Spring Hill Project benefits from granted mining leases and environmental approvals, positioning PC Gold to move swiftly through development milestones. The project’s Mineral Resource Estimate, reported under the JORC Code, currently stands at 25.6 million tonnes at 1.0 g/t Au for 821,000 ounces of gold, with a significant portion classified as Indicated and Inferred resources. The ongoing drilling and resource growth efforts aim to convert and expand this inventory, supporting the company’s dual-stream strategy of infill drilling and aggressive extensional exploration.
These developments follow PC Gold’s earlier successes in uncovering thick, high-grade zones extending the Main Zone strike and validating new discoveries such as the Macau Link Zone, which have collectively bolstered the project’s resource outlook and pre-feasibility progress. The company’s recent capital raising efforts have also strengthened its balance sheet to fund this accelerated drilling and development program.
As drilling continues and the June resource update approaches, PC Gold’s ability to convert these high-grade intercepts into a more robust and economically viable resource will be a critical factor for investors and stakeholders monitoring the project’s advancement.
Bottom Line?
The ongoing drilling success at Spring Hill signals potential for meaningful resource growth within the existing pit shell, but the true impact will hinge on the upcoming June resource update and subsequent feasibility studies.
Questions in the middle?
- How will the June resource update quantify the impact of new high-grade intercepts on overall tonnage and grade?
- Can PC Gold maintain drilling momentum and convert inferred resources to indicated or measured categories?
- What are the implications of mineralisation within previously classified waste zones for project economics and mine planning?
