Highlights

  • Basin Creek drilling confirms massive and semi-massive chalcopyrite and bornite sulphide mineralisation with significant gold credits.
  • DHEM surveys detect off-hole conductive plates coinciding with strike and plunge extensions of high-grade copper lenses.
  • LSA shares gained 88.53% over 12 months to $0.115, market cap $42.73 million.
  • Junee project lies along the Northparkes copper-gold porphyry trend; North Cobar targets world-class Cobar-style polymetallic deposits.

The Lachlan Fold Belt keeps yielding copper-gold surprises, and Lachlan Star (ASX:LSA) has found its own at Basin Creek — with geophysics pointing to more sulphides still to be drilled.

Basin Creek Yields Thick Copper-Gold Sulphides

Lachlan Star has delivered outstanding exploration momentum across the Lachlan Fold Belt of central-western New South Wales, headlined by rapid progression of diamond and reverse circulation drilling at the Basin Creek Copper-Gold Project. Detailed oriented drill core logging confirms exceptionally thick intervals of massive and semi-massive chalcopyrite, bornite, and pyrite associated with intense quartz-chlorite-sericite hydrothermal alteration. Significant gold credits accompany the copper sulphide mineralisation, verifying management's geological targeting models.

Modern downhole electromagnetic geophysical surveys have delineated high-priority off-hole conductive plates that coincide directly with projected plunge and strike extensions of known high-grade copper lenses. By systematically drill testing these validated geophysical conductors, Lachlan Star is rapidly delineating the structural geometry, continuity, and commercial scale of the mineralised body.

Multi-Project Scale: Junee and North Cobar

Complementing its Basin Creek success, Lachlan Star holds commanding land positions across the Junee and North Cobar projects. The Junee project occupies a strategic position along the Gilmore Suture and Northparkes copper-gold porphyry trend, where legacy exploration identified large-scale intrusive porphyry signatures. In the Cobar Basin, the company's tenure is exceptionally prospective for world-class, high-grade polymetallic Cobar-style deposits characterised by steep vertical continuity and high metal tenors.

The primary commodity focus unites copper and gold in a powerful dual-driver valuation model. Copper provides exposure to global energy transition infrastructure where long-term structural supply deficits are widening, while gold co-product credits deliver outstanding cash-margin expansion at historic high Australian-dollar bullion pricing.

Strong Annual Share Price Performance

Shares in Lachlan Star gained $0.005 or 4.55% to close at $0.115 on 2 October 2026, across an intraday band of $0.110 to $0.115 on volume of 38,972 shares. The company commands an equity market capitalisation of $42.73 million and has recorded an impressive 88.53% share price advance over the preceding 12-month period, reflecting sustained investor appreciation for high-grade discovery success.

The company maintains a healthy corporate balance sheet supported by prudent cash treasury management and successful oversubscribed equity placements that have fully funded ongoing multi-phase drilling campaigns without incurring debt.

Next Catalysts and Regional Scale

Immediate operational catalysts centre on the progressive release of laboratory assay results from step-out diamond drilling at Basin Creek. Confirming down-plunge extensions of thick copper-gold sulphides will establish the scale required to formulate a maiden JORC-compliant Mineral Resource Estimate.

Concurrently, the company is conducting high-resolution ground geophysics and geochemical vectoring across Junee to refine porphyry copper-gold drill targets. Initial maiden drill testing results at Junee will represent an important regional discovery milestone.

Exploration Risks

Delineating economic copper-gold deposits involves geological risk where mineralised lenses may experience structural offsets, faulting, or lower metal grades than projected by geophysical models. Advancing multi-basin exploration toward commercial resource evaluation requires substantial capital expenditure, creating ongoing dependency on equity capital markets.

Field activities across regional New South Wales are also subject to rigorous statutory regulatory approvals, environmental compliance standards, local landholder access agreements, and seasonal weather disruptions.
