KalGold Doubles Lighthorse Gold Strike Length, Eyes 2026 Drilling Expansion
Kalgoorlie Gold Mining has significantly extended the strike length of primary gold mineralisation at its Lighthorse Prospect to over 1,100 meters, confirming a large orogenic gold system open to further expansion. The company plans additional drilling in early 2026 to further delineate this promising target within the Tier One Pinjin Gold Project.
- Lighthorse primary gold mineralisation strike extended from ~600m to over 1,100m
- Gold mineralisation linked to shearing, alteration, sulphides, and veining in fresh rock
- Mineralised system remains open to the north, correlating with geophysical conductivity highs
- Follow-up infill and extensional RC drilling planned for early 2026
- Diamond drilling results pending from Kirgella Gift and Providence South prospects
Expanding the Lighthorse Footprint
Kalgoorlie Gold Mining Limited (ASX – KAL) has reported compelling results from its recent reverse circulation (RC) drilling campaign at the Lighthorse Prospect, part of its Pinjin Gold Project in Western Australia. The latest drilling has nearly doubled the strike length of primary orogenic gold mineralisation to over 1,100 meters, up from less than 600 meters in earlier programs. Importantly, this mineralised system remains open to the north, suggesting further potential for expansion.
The new drilling validates earlier aircore surveys that identified a broad near-surface gold anomaly stretching approximately 1,600 meters. The RC results confirm that this anomaly is sourced from a substantial primary gold system at depth, associated with extensive shearing, alteration, sulphide mineralisation, and quartz veining. Intercepts include thick mineralised zones, such as 35 meters at 0.33 g/t gold and 15 meters at 1.14 g/t gold, highlighting the quality and continuity of the system.
Geophysical Correlations and Structural Insights
The mineralisation aligns closely with a Sub-Audio Magnetic (SAM) magnetometric conductivity high, which extends beyond the current drilling limits. This geophysical signature acts as a valuable exploration guide, with KalGold engaging consultants to perform 3D inversion modelling to unlock further insights. The mineralised zones appear to dip steeply westward and are hosted within a complex sequence of volcanic and ultramafic rocks, typical of orogenic gold systems in the region.
KalGold’s Managing Director, Matt Painter, emphasised the significance of these findings, noting that the thick, laterally extensive gold zones are consistent with the company’s strategy to target large-scale deposits in the Pinjin region, a Tier One gold province. The proximity to Ramelius Resources’ Rebecca Gold Project, just 25 kilometers to the south, underscores the strategic importance of the area.
Broader Exploration and Upcoming Programs
Beyond Lighthorse, KalGold has also identified primary gold mineralisation at the Wessex and Providence South prospects, following up on earlier aircore anomalies. While Wessex drilling returned some low-grade results, Providence South showed promising intercepts, including 2 meters at 2.40 g/t gold.
Diamond drilling at Kirgella Gift and Providence is underway, with assays pending. These results will be critical to understanding the depth and continuity of mineralisation across the broader Pinjin corridor.
Looking ahead, KalGold plans an aggressive drilling campaign in early 2026, comprising both infill and step-out RC drilling at Lighthorse to better define the mineralised envelope and test the northern extensions along the SAM conductivity ridge. Additionally, first-pass aircore drilling is planned to evaluate peripheral targets, including historic Newmont prospects and new geophysical anomalies along the Laverton Tectonic Zone.
Strategic Positioning in a Prolific Gold Belt
The Pinjin Gold Project sits within the prolific Laverton Tectonic Zone, a major crustal structure hosting some of Australia’s most significant gold deposits. KalGold’s growing footprint, including the Kirgella Gift and Providence deposits with an inferred resource of over 76,000 ounces, positions the company well to unlock value in this underexplored region.
KalGold’s approach focuses on defining shallow, potentially open-pittable gold resources at low cost, with current production costs estimated below A$4.60 per ounce. The recent drilling success at Lighthorse adds a substantial new target to the company’s portfolio, reinforcing its potential to deliver significant resource growth in the near term.
Bottom Line?
KalGold’s expanded Lighthorse discovery sets the stage for a pivotal 2026 drilling campaign that could reshape the company’s resource profile and market standing.
Questions in the middle?
- How will pending diamond drilling results from Kirgella Gift and Providence influence resource estimates?
- What is the potential scale and grade of mineralisation beyond the current northern limits of Lighthorse?
- How might 3D inversion modelling of SAM geophysical data refine target prioritisation and drilling strategies?
