Lachlan Star Expands New Waverley Drilling After Confirming High-Grade Gold Shoots
Lachlan Star has confirmed shallow, high-grade gold mineralisation at New Waverley, prompting an expanded 4,000m drilling program to test extensions and increase density along a mineralised shear corridor open in all directions.
- Final assays confirm high-grade quartz vein shoots
- Follow-up RC drilling expanded to 4,000m starting July
- Mineralised shear corridor open with potential 800m+ strike
- Concurrent soil sampling and historical dump assessment underway
- Metallurgical test work on dump material pending
High-Grade Gold Confirmed in Maiden Drilling
Lachlan Star Limited (ASX:LSA) has delivered a compelling update from its New Waverley Gold Project in Western Australia's Norseman district, confirming and extending shallow, high-grade gold mineralisation from its maiden 13-hole diamond drilling program. The final assays reveal discrete quartz vein-hosted shoots within a broader shear corridor, with intercepts like 6.15m at 8.6g/t Au and narrower zones exceeding 20g/t Au. These findings underpin a geological model consistent with other prolific Norseman deposits such as North Royal and Harlequin mines.
Expanded Drilling to Target Down-Plunge and Along-Strike Extensions
Buoyed by these results, Lachlan Star has expanded its upcoming Reverse Circulation (RC) drilling program to approximately 4,000 metres, up from earlier plans. Scheduled to commence in early July, the program aims to increase drill density around known high-grade shoots and test their continuity down-plunge and along the mineralised corridor, which currently shows strike potential exceeding 800 metres and remains open-ended in all directions. Earthworks are underway to facilitate the drilling.
Broadening the Exploration Footprint with Soil Sampling and Dump Assessment
In parallel with drilling, the company is advancing an extensive soil geochemistry survey covering about 4 kilometres of strike along the southwestern extension of the mineralised shear corridor. This program, comprising approximately 900 sample sites, is designed to detect subtle geochemical anomalies and refine future drill targets. Meanwhile, Lachlan Star has completed a 1,095-metre Aircore (AC) drilling program on historical mine dump material within the mining lease, aiming to assess grade distribution and processing potential. Assay results and metallurgical test outcomes, including gravity and leach studies on composite dump samples, are expected by late July.
Geological Insights Support Targeting Strategy
The drilling has established a consistent north-westerly plunge orientation to the higher-grade shoots within a north-northeast striking shear corridor. This structural understanding provides a predictive framework for targeting additional mineralisation both down plunge and along strike. The mineralisation style and geometry align with classic Norseman-style systems, characterised by gold-rich quartz reefs within shear zones enhanced by cross-cutting structures.
Project Positioned in a Prolific Gold District
New Waverley lies approximately 16 kilometres northeast of Norseman, positioned between Lachlan Star’s Killaloe Project and Pantoro Gold’s Norseman Gold Project, which boasts a 4.6 million ounce resource. The project includes granted mining leases containing historical shallow workings and an exploration licence, covering a ~40 square kilometre package underlain by the Woolyeenyer Formation; a key host to gold mineralisation in the district.
Bottom Line?
The expanded drilling and concurrent exploration initiatives at New Waverley set the stage for a steady stream of results that will clarify the project’s scale and economic potential over the coming months.
Questions in the middle?
- Will the expanded RC drilling confirm down-plunge continuity of high-grade shoots?
- How will metallurgical test results on historical dump material influence project economics?
- Can soil sampling identify new targets extending the mineralised corridor beyond current limits?
