Warriedar Resources Limited (ASX: WA8) (Warriedar or the Company) provides an update on its initial review of the antimony (Sb) potential at the Ricciardo deposit, located within its Golden Range Project in the Murchison region of Western Australia.
HIGHLIGHTS:
- Review of the antimony (Sb) potential at Ricciardo is complete with drillhole assay data confirming Sb mineralisation of significant thickness and grade exists below both the Ardmore pit (previously identified) and the Copse-Silverstone pits (newly identified), representing a potential combined strike length of approx. 1km.
- Multiple significant Sb intervals have been identified (reviewing both historic and WA8 drill hole assays), in addition to results recently released (* indicated below):
- Most of the Sb mineralisation appears to be located above the main gold zone, a distinct metallurgical positive for future processing and economic potential. Similarly to the gold mineralisation, the Sb zones remain wide open at depth.
- Only 11% of historical drill samples at Ricciardo were assayed for Sb. Retained pulp samples from historical holes are currently being tested with pXRF, with those favourable for significant Sb set to undergo laboratory multi element assay.
- An approx. 100kg high-grade sample of antimony mineralisation from Ricciardo has also been dispatched for scoping-level metallurgical testwork.
Warriedar Managing Director and CEO, Amanda Buckingham, commented:
“Following the recent high grade antimony intersections at Ricciardo, our initial review of the broader antimony potential has delivered further promise. An exceptionally high-grade antimony interval, as well as a much wider intersection, are now able to be placed in greater context. This context is a broader volume of antimony, not yet well-defined but with existing drilling showing serious scale and grade potential.
“Importantly, the high-grade antimony appears relatively discrete from higher-grade gold mineralisation, an excellent metallurgical outcome. While it remains early days, we are cautiously optimistic and have commenced initial metallurgical testing for potential processing and antimony recovery.
“While we are excited about this emerging opportunity at Ricciardo, I want to emphasise however that pursuit of this opportunity will be in parallel with our growth-focussed gold drilling at Golden Range, which remains our current core focus.”

Key Ricciardo context
The Ricciardo gold system spans a strike length of approximately 2.3km, with very limited drilling having been undertaken below 100m depth. Ricciardo possesses a current Mineral Resource Estimate (MRE) of 8.7 Mt @ 1.7 g/t Au for 476 koz gold.1
Historical gold mining operations at Ricciardo were primarily focused on the oxide material, with the transition and primary sulphides mineralisation not systematically explored. Antimony was not a focus of previous exploration, with only about 11% of historic drill holes assayed for antimony.
The gold and antimony mineralisation at Ricciardo is predominantly hosted within intensely altered and deformed ultramafic units. The high-grade antimony-dominant mineralisation occurred later than the main gold events and generally sits above the high-grade gold mineralisation.
