Edjudina Gold Project Drilling Yields 9m at 3.13g/t Gold, Mining Permits Granted

Strong Drilling Results Reinforce Neta’s Potential

Gibb River Diamonds Limited (ASX – GIB) has announced encouraging results from its Phase 1 grade control drilling program at the Neta Gold Prospect, part of the Edjudina Gold Project in Western Australia. Conducted in July 2025 by joint venture partner and private mining contractor BML Ventures Pty Ltd, the program comprised 65 reverse circulation drill holes totaling 2,180 metres. The results confirm the presence of consistent, high-grade gold mineralisation starting right at surface, a promising indicator for near-term mining operations.

Among the standout intersections, drillhole 25NRC017 returned 9 metres at 3.13 grams per tonne (g/t) gold from 80 metres depth, highlighting a new high-grade shoot target that could significantly enhance the resource’s value. Other notable intercepts include multiple intervals exceeding 3 g/t gold, with some mineralisation hosted within a shallow calcrete cap, suggesting both primary and transported gold deposits.

Mining Permits and Operational Readiness

The Western Australian Mines Department recently granted the Mining Proposal Permit (Part 1) for the Neta Prospect, a critical regulatory milestone that authorises the commencement of mining activities. In line with this, BML Ventures has indicated plans to mobilise plant and equipment during August 2025 to prepare the site for mining operations. This rapid progression from drilling to mining readiness underscores the project’s advancing development trajectory.

The Phase 1 drilling data will be integrated with existing geological models to refine grade control and support mining planning. BML is currently assessing whether a Phase 2 grade control drilling program is warranted, which could further delineate the resource and optimise extraction strategies.

Historical Context and Project Significance

The Edjudina Gold Project has a rich exploration history dating back to the late 19th century, with intermittent mining and exploration activities over the decades. Gibb River Diamonds has steadily advanced the project through systematic drilling campaigns and strategic partnerships. The Neta Prospect’s JORC-compliant resource currently stands at 378,000 tonnes at 1.9 g/t gold for approximately 24,000 ounces, including a higher-confidence Indicated Resource of 110,000 tonnes at 2.2 g/t for 8,000 ounces.

Geologically, the gold mineralisation is stratabound within silicified stromatolites and associated with quartz-carbonate alteration, a style that supports coherent and discrete ore zones amenable to efficient mining.

Looking Ahead

The board of Gibb River Diamonds expressed optimism about the drilling outcomes and the project’s momentum. With mining permits secured and operational mobilisation imminent, the company is poised to transition from exploration to production. Investors will be watching closely for updates on the Phase 2 drilling decision and the commencement of mining activities, which could unlock further value from the Edjudina Gold Project.
