Lighthorse Corridor: 13 km Strike Zone Drives KalGold’s Next Drilling Phase

Expanding the Lighthorse Gold Corridor

Kalgoorlie Gold Mining (ASX: KAL) is intensifying its exploration efforts around the recently announced Lighthorse gold discovery within its Pinjin Project, located approximately 140 km northeast of Kalgoorlie-Boulder. The company has delineated a substantial 13-kilometre-long north-south trending geological corridor hosting the discovery, with around 6 kilometres of this strike length now earmarked for priority drilling.

This corridor, described as the "Lighthorse Corridor," is characterized by a sheared and deformed volcano-sedimentary sequence within the prolific Laverton Tectonic Zone, a region known for hosting some of Western Australia's largest gold deposits. The corridor is flanked by magnetic ridges interpreted as chert or banded iron-formation, which may play a structural role in localising gold mineralisation.

New Undrilled Targets and Historical Drilling Review

Significantly, KalGold has identified multiple undrilled target areas immediately north and south of the Lighthorse discovery. To the north, two undrilled strike zones of 1,500 m and 1,200 m respectively remain untested, with magnetic and structural anomalies suggesting potential for further mineralisation. To the south, historic drilling, primarily shallow RAB and aircore, was irregular and likely ineffective in fully testing the gold potential, particularly at the T15 prospect where transported cover exceeds 100 metres.

The company is currently reassessing the effectiveness of this historic drilling to determine where systematic redrilling is warranted. This review is critical given that some historic holes may not have penetrated fresh bedrock adequately, leaving primary gold mineralisation at depth untested.

Upcoming Drilling Programs and Strategic Outlook

KalGold plans to commence a follow-up reverse circulation (RC) drilling program in early March 2025, targeting high-grade mineralisation beneath and around the initial Lighthorse intercepts. This program is the first in a series designed to systematically test the strike extensions of the discovery.

Complementing the RC drilling, the company will deploy widely spaced aircore drilling along strike to efficiently cover the newly identified target zones. The exploration strategy aims to define the full extent of the gold mineralised system, with the potential to significantly expand KalGold’s resource base.

Managing Director Matt Painter expressed optimism about the scale of the system, noting that if mineralisation comparable to the initial Lighthorse results is encountered along the multi-kilometre trend, it could represent a transformational development for the company.

Context Within the Pinjin Project and Regional Significance

The Pinjin Project sits within a Tier One gold province, adjacent to Ramelius Resources’ Rebecca Gold Project, which is advancing towards production. KalGold’s portfolio includes other notable assets such as the La Mascotte deposit and the Kirgella Gift and Providence deposits, collectively underpinning a growing presence in the Laverton Tectonic Zone.

KalGold’s approach of targeting shallow, potentially open-pittable gold resources at low cost aligns well with the region’s prolific gold endowment and infrastructure. The company’s ongoing exploration success at Lighthorse and surrounding targets will be closely watched by investors seeking exposure to emerging gold discoveries in Western Australia.
