Structural setting compares to Ghost Crab (1.2Moz) and Gwalia (3.5Moz+)

Near-surface Archaean lode gold, open at depth, with a live drill program testing the extensions

Lady Bell is a structurally controlled gold deposit within Rocktivity’s Nepean Project area, roughly 10km south of the Nepean Nickel Mine and 65km south-east of Kalgoorlie-Boulder in the Eastern Goldfields of Western Australia. Mineralisation sits within a north-northwest trending shear corridor cutting through mafic and ultramafic stratigraphy, hosting free gold and fine-grained pyrite-associated gold in quartz-carbonate veins. The deposit remains open at depth and along plunge, with strong exploration upside inside the same mine infrastructure footprint.

Rocktivity’s Approach

Lady Bell is being advanced as a conventional open-pit operation targeting the near-surface, shallow-dipping portions of the lode system, with standard 5-metre mining benches and electronic-detonation blast design to control dilution. Ore is trucked to a run-of-mine pad for toll treatment through nearby processing infrastructure, avoiding the capital cost and execution risk of a standalone plant and providing a faster path to first gold. Mineralisation is currently confirmed to less than 100 metres below surface and remains open at depth, with a 1,000-metre drill program completed in December 2025 testing those extensions.

An independent structural assessment found Lady Bell shares the same geological architecture as two of Australia’s most significant gold deposits:

Ghost Crab — 1.2Moz in a 200m-wide shoot to 1,500m depth (full scale not understood until four years after discovery)

Gwalia — 3.5Moz+, mined beyond 3,000m depth and still St Barbara’s flagship asset

  • Lady Bell has never been drill-tested for depth continuity
  • 1,000m extensional drill program completed December 2025, assays pending
  • Ore thickness 1–15m true width; open at depth and along plunge
