Highlights

  • Gibb River Diamonds secured 21-year statutory mining leases over the legendary Ellendale Diamond Project in WA.
  • Ellendale historically supplied approximately 50% of global fancy yellow diamond production.
  • The company targets low-capital alluvial extraction to bypass the capital hurdles of previous hard-rock operators.
  • Edjudina Gold Project in the Eastern Goldfields provides complementary high-grade gold upside.

Half the world's fancy yellow diamonds once came from a field in the West Kimberley — and Gibb River Diamonds (ASX:GIB) has just secured 21-year mining leases over that field, the legendary Ellendale Diamond Project, with a strategy that sidesteps the capital-intensive hard-rock approach that undid previous operators.

Ellendale: A Legendary Global Provenance

The Ellendale Diamond Project carries prestigious global provenance, historically supplying approximately 50% of the world's rare, high-value fancy yellow diamonds under exclusive marketing agreements with premier luxury jewellers including Tiffany and Co. GIB's granted tenure encompasses extensive diamondiferous alluvial channel systems, eluvial gravel deposits, and lamproite pipe stockpiles.

The granting of 21-year statutory mining leases marks a decisive transition from protracted tenure applications to commercial restart execution. The focus on shallow alluvial and eluvial gravel deposits rather than capital-intensive open-pit hard-rock mining aims to bypass the massive capital expenditure hurdles that challenged previous operators, targeting modular, low-cost processing that accelerates free cash generation.

Edjudina: Gold Diversification in the Eastern Goldfields

Gibb River Diamonds maintains strategic precious metal diversification through its 100%-owned Edjudina Gold Project in the Keith-Kilkenny greenstone tectonic corridor of Western Australia's Eastern Goldfields. Edjudina hosts numerous historic high-grade workings including the Neta and Carlindi prospects, with shallow drilling confirming significant high-grade gold intercepts.

This dual-commodity portfolio provides uncorrelated upside exposure. Premium fancy yellow diamonds trade at scarcity-driven premiums insulated from synthetic diamond price erosion, while gold provides counter-cyclical economic resilience at high Australian-dollar cash margins.

Development Roadmap at Ellendale

GIB's immediate focus is concluding Native Title mining agreements and obtaining environmental clearing permits across the Ellendale mining leases, unlocking ground access for trial bulk-sampling and dry-screening operations across the high-priority E9 Alluvial channel.

Management is assessing staged processing plant configurations including modular trommel and dense media separation units. Strategic partnership discussions with diamond marketing houses and European luxury buyers offer non-dilutive development options. GIB shares closed at $0.031 with no recorded volume on 2 October 2026, establishing a market capitalisation of $6.65 million.

Funding, Seasonal, and Market Risks

GIB's limited cash treasury necessitates external funding injections, commercial debt, or joint-venture farm-ins to finance plant procurement and site infrastructure. Dilution remains prominent if funding relies primarily on equity placements.

Remote operations in the Kimberley are subject to seasonal tropical monsoons restricting physical ground access during wet season months. Diamond pricing is also highly sensitive to gemstone cutability, colour saturation, and global discretionary luxury demand trends — factors that fall outside the company's operational control.
