KalGold Kicks Off 6,850m RC Drilling at Pinjin to Expand Kirgella Gift and Lighthorse Resources

Major RC Drilling Campaign Starts at Pinjin

Kalgoorlie Gold Mining (ASX:KAL) has mobilised a reverse circulation (RC) drill rig to commence a 41-hole, 6,850-metre drilling program at its flagship Pinjin Gold Project, located roughly 140 kilometres northeast of Kalgoorlie-Boulder. The campaign is focused on the Kirgella Gift and Providence gold deposits, alongside the Lighthorse prospect, aiming to both infill and extend known mineralisation.

The Kirgella Gift-Providence targets will see 22 holes drilled over 3,600 metres, concentrating on areas within the existing JORC Code (2012) Inferred Mineral Resource Estimate (MRE) of 2.34 million tonnes at 1.0 g/t gold for approximately 76,000 ounces. Selective drilling will also test extensions to the north and west, supporting a forthcoming resource update. Meanwhile, 19 holes totalling 3,250 metres will target the Lighthorse prospect, seeking to tighten previous RC coverage and explore northern strike extensions aligned with Sub-Audio Magnetic (SAM) geophysical anomalies.

Strategic Location in a Prolific Gold Belt

Pinjin sits within the Laverton Tectonic Zone (LTZ), a Tier One gold province hosting major operations such as Sunrise Dam and Granny Smith. KalGold’s project lies just 25 kilometres north of Ramelius Resources’ (ASX:RMS) Rebecca Gold Project, which is advancing towards production by 2027. This proximity underscores the strategic value of KalGold’s tenure in a region with proven gold endowment and infrastructure.

KalGold’s approach targets shallow, potentially open-pittable deposits at low costs, currently under A$4.60 per ounce. The company’s total gold resource exceeds 214,000 ounces, including the 138,000-ounce La Mascotte deposit near Kalgoorlie. The current drilling aligns with KalGold’s strategy of building resources through systematic exploration across its portfolio.

Broader Drilling and Exploration Plans

The six-week RC program complements planned diamond drilling at Kirgella Gift to test vertical continuity and first-pass aircore drilling over a structural flexure in the LTZ to the east. These additional programs aim to deepen geological understanding and identify new mineralised zones, building on recent successes such as the discovery of thick, primary gold mineralisation at Lighthorse and Kirgella Gift documented in earlier drilling campaigns.

This drilling campaign follows KalGold’s recent announcement of its largest exploration push at Pinjin, which included plans for up to 215 aircore holes and deep diamond drilling to refine resource models and test untested targets. The company’s ability to coordinate multiple drill programs amid high rig demand demonstrates operational flexibility and commitment to resource growth.

KalGold’s Managing Director Dr Matthew Painter, who also serves as the Competent Person for exploration results, emphasises the potential for resource expansion in this underexplored section of the LTZ. The company’s previous diamond drilling intersected thick gold mineralisation extending well below current inferred resources, supporting the rationale for ongoing resource definition and extension drilling.

Investors should note that while the current drilling is designed to support resource upgrades, no new resource estimates have been released yet. The company confirms that all material assumptions underpinning existing resource estimates remain valid, with assay results from the current program expected in due course.

KalGold’s drilling activity at Pinjin is part of a broader trend of aggressive exploration in the Eastern Goldfields, where companies are leveraging geophysical data and structural interpretations to unlock new gold zones. The integration of SAM geophysical surveys with drilling exemplifies this modern exploration approach, potentially enhancing targeting precision.

For context, KalGold’s ongoing efforts at Pinjin have been highlighted in recent coverage detailing the company’s largest ever drilling campaign, which aims to capitalize on the project’s geological potential and proximity to established gold operations. This campaign represents a critical step in validating and expanding KalGold’s resource base in a competitive gold district.
