Lachlan Star Confirms High-Grade Gold Continuity at New Waverley

Shallow High-Grade Gold Validated Beneath Historical Workings

Lachlan Star Limited (ASX:LSA) has delivered compelling confirmation of high-grade gold mineralisation at its New Waverley Gold Project in Western Australia’s Norseman district, with assays from the first six holes of its maiden 13-hole diamond drilling program revealing impressive shallow intercepts. Highlights include 6.15 metres at 8.6 grams per tonne (g/t) gold from just 46.9 metres downhole, including a 2.9-metre section grading 17.7g/t Au, and 4.6 metres at 4.24g/t Au starting at 18.5 metres. These results underpin the presence of a stacked quartz vein system hosted within a north-northeast trending shear corridor, which remains open along strike and at depth.

The drilling tested beneath historical open-cut workings, successfully validating the continuity of mineralisation that had been suggested by rock-chip samples up to 56g/t Au and historical drill intercepts exceeding 50g/t Au in narrower zones. This breakthrough supports a structural model of a west-dipping shear corridor extending at least 400 metres with potential strike continuity beyond 800 metres, a scale that significantly enhances the project’s exploration upside. The presence of visible gold alongside pyrite and pyrrhotite sulphides within laminated quartz veins adds geological weight to the prospectivity of the system.

Follow-Up Drilling to Target High-Grade Shoot Extensions

Building on these encouraging results, Lachlan Star is preparing for a substantial ~2,400-metre reverse circulation (RC) drilling campaign scheduled for June. The program aims to infill and extend the known mineralisation, prioritising the higher-grade down-plunge shoots identified through geological logging and structural interpretation. The company’s CEO, Andrew Tyrrell, emphasised that the maiden diamond drilling has provided a robust framework for targeting these zones, which are critical to defining the resource potential of New Waverley.

The drill program complements ongoing efforts to evaluate historical mine waste dumps via an aircore drilling program planned for late May, targeting grade and continuity assessment that could unlock additional economic value. A drone magnetics survey, co-funded by the WA Government’s Exploration Incentive Scheme, is also slated to enhance structural understanding across the tenure.

Strategic Location in a Prolific Gold District

New Waverley sits within the highly endowed Norseman mining district, approximately 16 kilometres northeast of Norseman town, flanked by Lachlan Star’s Killaloe Gold Project and Pantoro Gold Limited’s Norseman Gold Project, which hosts a 4.6 million ounce resource. The project covers about 40 square kilometres underlain by the Woolyeenyer Formation, a key host for gold mineralisation in the region.

Historical mining at New Waverley was shallow, with workings extending to around 30 metres depth at Waverley Pit and 6 metres at Trial Pit, leaving substantial untested potential down-plunge and along strike. Lachlan Star’s recent drilling confirms the mineralised system is a classic Norseman-style quartz reef gold system, with gold-rich quartz veins hosted within a mafic sequence of basalt, dolerite, and gabbroic intrusives.

Continuity and Structural Controls Strengthen Project Prospects

The drilling results reinforce the interpretation of a stacked lode system with a consistent northwesterly plunge component controlling higher-grade shoots. This structural control is crucial for targeting future drilling and resource delineation. The company’s methodical approach, combining diamond and RC drilling with geophysical surveys and waste dump evaluation, indicates a well-rounded exploration strategy aiming to rapidly advance New Waverley’s prospectivity.

These findings build on Lachlan Star’s recent acquisition and capital raise efforts, including a $7.47 million placement to accelerate exploration activities. The maiden diamond drilling results, combined with the upcoming RC program and other exploration initiatives, position New Waverley as a compelling addition to the Norseman gold district portfolio, as previously detailed in the company’s $7.47M Raise to Fast-Track and Maiden Drilling at New Waverley announcements.
