Warriedar Extends High-Grade Gold-Antimony Shoots at Ricciardo

Strong Drill Results at Ricciardo

Warriedar Resources Limited (ASX – WA8) has announced the first full-hole assay results from diamond drill hole RDRC069 at the Ardmore end of its flagship Ricciardo gold-antimony deposit in Western Australia. The hole, part of a four-hole diamond drilling program completed in May 2025, returned multiple high-grade intercepts of gold and antimony across significant widths, confirming the down-plunge continuity of high-grade shoots previously identified at Ardmore.

Highlights include a 24-metre intercept grading 0.99% antimony and 1.55 grams per tonne gold (3.65 g/t gold equivalent) from 170 metres depth, with narrower zones within this interval showing even higher grades, such as 3.1 metres at 4.06% antimony and 0.30 g/t gold, and 6 metres at 0.54% antimony and 4.41 g/t gold. Additional notable intercepts include 10 metres at 0.91% antimony and 1.58 g/t gold, and 7 metres at 1.34% antimony and 1.75 g/t gold, underscoring the deposit’s robust mineralisation.

Mineralogy Confirms Stibnite Dominance

Complementing the assay results, a mineralogy study using the ELEMISSION ECORE Laser-Induced Breakdown Spectroscopy (LIBS) technology confirmed that conventional stibnite (Sb2S3) constitutes over 99% of the antimony mineralisation at Ardmore. This finding is significant as it supports the potential for conventional processing methods and metallurgical recoveries, which Warriedar has assumed at 90% based on analogous Australian projects.

Ricciardo’s Strategic Position and Growth Potential

The Ricciardo deposit, situated within the Golden Range Project in the Murchison region, is notable for hosting Australia’s largest open-pit antimony resource alongside substantial gold mineralisation. Warriedar’s recent drilling campaigns have doubled the Mineral Resource Estimate twice within six months, with the latest May 2025 update reporting 24.5 million tonnes at 2.5 g/t gold equivalent, containing nearly 2 million ounces of gold equivalent including over 60,000 tonnes of antimony.

Located on mining leases fully owned by Warriedar, Ricciardo benefits from proximity to existing infrastructure, including the Golden Range process plant 8 kilometres north. The deposit’s mineralisation remains open at depth and along strike, with the Ardmore area hosting the largest known high-grade shoots. The new drill results from RDRC069 extend these shoots beyond the current resource model, indicating further upside potential.

Ongoing Drilling and Future Outlook

Warriedar is accelerating its drilling efforts at Ricciardo, with multiple rigs currently active to delineate extensions and support metallurgical studies. Managing Director Amanda Buckingham highlighted the significance of these results, emphasizing the combined scale and grade of gold and antimony mineralisation that make Ricciardo an attractive development opportunity.

As the company continues to integrate new data, investors will be watching closely for further assay results and updates on resource growth and processing plans. The confirmation of stibnite dominance and consistent high-grade shoots strengthens the case for Ricciardo’s potential as a major gold-antimony producer in Australia.
