Warriedar Resources (ASX:WA8) Ricciardo: An antimony sleeper awakens

For decades, Western Australia’s Murchison region has been synonymous with gold mining, but Warriedar Resources (ASX: WA8) may be rewriting the script with an emerging antimony play that is quietly gathering momentum.

The latest historical pulp assay results from the Ricciardo deposit within the Golden Range Project suggest that the company may be sitting on an antimony resource of global relevance.

Warriedar Resources has identified multiple wide and high-grade antimony zones, with highlights including:

• 49m @ 1.31% Sb and 0.80 g/t Au (3.57 g/t AuEq) from 42m (SSRC104), including 3m @ 10.87% Sb and 2.56 g/t Au (25.6 g/t AuEq)
• 64m @ 0.54% Sb and 0.71 g/t Au (1.85 g/t AuEq) from 38m (SSRC106A), including 3m @ 3.00% Sb and 1.00 g/t Au (7.4 g/t AuEq)
• 50m @ 0.42% Sb and 0.62 g/t Au (1.52 g/t AuEq) from 46m (SSRC105), including 1m @ 4.75% Sb and 0.43 g/t Au (10.49 g/t AuEq)

With these results, Warriedar is fast-tracking a maiden antimony Mineral Resource Estimate (MRE) for early Q2 2025.

A Critical Metal in High Demand

While gold remains the company’s primary focus, antimony is no sideshow.

The metalloid is essential for flame retardants, batteries, and military applications, yet supply is precariously dependent on China and Russia.

With the West scrambling to secure alternative sources, Ricciardo’s antimony-rich veins could prove lucrative.

Warriedar CEO Amanda Buckingham sees significant upside, she said:

“At very low cost, the re-assaying of the historical pulp samples has allowed us to more fully define the sizeable and high-grade antimony potential at our flagship Ricciardo deposit,”

Rewriting Ricciardo’s Story

Historically, Ricciardo was drilled for gold, with little attention paid to elements like antimony.

Recent work shows that high-grade antimony mineralisation extends from the bottom of the historical Ardmore pit to a depth of approximately 370m—and remains open at depth.

The company is now systematically evaluating additional historical drilling samples along the broader ‘Golden Corridor’ within Golden Range.

Given that only 9.5% of Ricciardo’s total assay dataset includes antimony testing, the resource upside remains significant.

Market Implications

The antimony price, hovering around US$15,000 per tonne, adds intrigue. Ricciardo’s gold-equivalent (AuEq) calculations reflect antimony’s economic impact, applying a 2.12x multiplier to Sb grades.

If Warriedar’s MRE confirms continuity and scale, the project could draw interest from downstream players seeking secure antimony supply.

With additional drilling underway and a maiden MRE imminent, Warriedar is positioning Ricciardo not just as a gold deposit, but as a potentially strategic critical mineral asset.

For investors, it’s a reminder that sometimes, the real prize isn’t what you started digging for.
