RC Drilling Reveals Thick Gold Zones Beyond Existing Resource
Kalgoorlie Gold Mining (ASX:KAL) has confirmed that its recent reverse circulation (RC) drilling program at the Kirgella Gift and Providence deposits within the Pinjin Gold Project has intersected broad zones of gold mineralisation extending beyond the current JORC Inferred Mineral Resource Estimate (MRE) of 2.34 million tonnes at 1.0 g/t Au for 76,400 ounces. The 21-hole, 3,702-metre campaign delivered several notable intercepts, including a standout 28 metres at 1.15 g/t Au from just 20 metres depth at Kirgella Gift, and 13 metres at 1.54 g/t Au from 44 metres at Providence.
These results reinforce the prospectivity of the shear-hosted, ultramafic-hosted gold system, with mineralisation remaining open both at depth and along strike. The thick intervals, some up to 38 metres, were often associated with alteration, sulphides and quartz veining, highlighting the geological continuity of the system. KalGold’s Managing Director Matt Painter emphasised that the drilling has extended the footprint of mineralisation beyond the current resource boundaries, providing a strong platform for future resource updates and targeted follow-up drilling.
Geological Controls and Structural Complexity
The company’s drilling program also shed light on the structural framework controlling gold distribution. Mineralisation is concentrated within strongly sheared ultramafic rocks, offset by major northeast and southeast trending faults. Secondary, lower-order structures further modulate the gold continuity, complicating the geometry but offering multiple exploration targets. Notably, drilling north of the current resource at Kirgella Gift returned mixed results, suggesting faulting may limit mineralisation continuity in that direction.
Two widely spaced holes testing a potential westerly offset lode position encountered limited gold anomalism, indicating that the main mineralised trend remains the primary focus. Meanwhile, the gap zone between Kirgella Gift and Providence showed minor anomalism but lacked significant intercepts at shallow depths, though deeper continuity remains a possibility.
Ongoing and Planned Exploration at Pinjin
KalGold is advancing multiple drill programs across the Pinjin Project to build on these encouraging results. First-pass aircore drilling at the Laverton Tectonic Zone (LTZ) Flexure target, approximately 3.5 km southeast of Kirgella Gift-Providence, is nearing completion with up to 225 holes planned. Concurrently, RC drilling at the Lighthorse prospect is underway, following up prior aircore and RC results that defined gold mineralisation over a 1.45-kilometre strike length.
Looking ahead, KalGold plans diamond and RC drilling beneath Kirgella Gift and Providence to test for depth extensions of primary gold mineralisation, which could further expand the resource. Additional aircore programs will target the high-metamorphic-grade Rebecca Sequence to the northeast, a geological unit analogous to the host rocks of Ramelius Resources’ nearby Rebecca Gold Project.
Strategic Positioning in a Tier One Gold Province
The Pinjin Project’s location within the prolific Laverton Tectonic Zone, a major crustal structure hosting some of Australia’s largest gold mines, situates KalGold in a highly strategic position. The project lies just 25 kilometres north of Ramelius Resources’ Rebecca Gold Project, which is advancing towards mining commencement in late 2027. KalGold’s ongoing exploration efforts demonstrate a methodical approach to unlocking the district’s potential, steadily building a portfolio of shallow, potentially open-pittable gold resources at low cost.
With a total gold resource across its portfolio exceeding 214,000 ounces, including the La Mascotte deposit and Central Yandal projects, KalGold is leveraging its expertise to systematically grow its footprint in Western Australia’s gold belts. The recent drilling success at Kirgella Gift and Providence adds momentum to this strategy, highlighting the potential for resource growth and new discoveries within the Pinjin tenure.
Bottom Line?
KalGold’s latest drilling extends gold mineralisation beyond current resources, setting the stage for deeper and broader exploration to define a growing gold camp at Pinjin.
Questions in the middle?
- How will pending assay results from ongoing aircore and RC programs influence the next resource update?
- To what extent could deeper drilling beneath Kirgella Gift and Providence unlock significant new gold ounces?
- How might structural complexities and faulting affect the continuity and mining potential of the Pinjin deposits?
