The importance of antimony extends across multiple industries. It is commonly used in flame-retardant materials for electronics, textiles, plastics, and construction products. Antimony compounds are also critical in lead-acid batteries, which continue to support automotive, backup power, and industrial energy storage systems. Emerging technologies are further driving long-term demand growth.

Governments and industries are prioritising the development of domestic critical mineral projects to reduce geopolitical risks. This trend creates opportunities for projects such as Antimony Ridge, where promising recovery rates can enhance future supply diversification. The ability to produce antimony efficiently within the United States could support national industrial and defence objectives.

Major milestones are positioning RML as an emerging US-focused antimony, tungsten, and gold player with a growing end-to-end development pathway.

🔎 Key Highlights

Phase 2 drilling underway with up to 45 holes planned

Best intercept to date: 189.2m @ 1.30 g/t Au

A$20M placement secured to accelerate growth initiatives

FAST-41 status granted by the White House

Processing mill acquired to strengthen integrated development strategy

Tungsten stockpiles confirmed with metallurgical upside

Maiden Mineral Resource Estimate targeted for Q1 2027

Dual ASX + NASDAQ listing strategy progressing

Strategic focus on supporting US defence & domestic supply chains

🌎 Why It Matters

Antimony and tungsten are classified as critical minerals by the United States due to their importance in defence systems, ammunition, aerospace, semiconductors, energy infrastructure, and advanced manufacturing.

With global supply chains tightening and Western nations pushing for domestic supply security, projects like Horse Heaven are becoming increasingly strategically important.

🚀 Investor Takeaway

With drilling, permitting, metallurgy, infrastructure, and funding all advancing simultaneously, RML is rapidly positioning Horse Heaven as a strategically important US critical minerals project with multiple near-term catalysts ahead.

Golden Gate offers significant exploration upside due to its mineralized structures and underexplored zones. Previous studies have indicated strong potential for valuable mineral deposits, encouraging further drilling to confirm continuity and grade distribution. This confidence supports why Resolution Minerals launches largest drill program yet at Golden Gate as two rigs hit the ground.

The project area benefits from favorable infrastructure access and exploration conditions, which help improve drilling efficiency and reduce operational delays. These practical advantages allow exploration teams to move faster and generate meaningful results sooner. Such conditions strengthen the decision as Resolution Minerals launches largest drill program yet at Golden Gate as two rigs hit the ground.

At the same time, the company is advancing separate concentration studies for antimony and gold at IMO laboratories in Perth, Australia. This multi-commodity approach increases the broader value proposition of the Horse Heaven Project and supports diversified revenue potential.

Critical minerals projects attract attention because they connect directly to electric mobility, renewable energy, military readiness, and manufacturing independence. These sectors continue receiving substantial policy and private-sector support.

One of the most notable outcomes of the announcement was the immediate market response. Resolution Minerals secures White House FAST-41 status for Antimony Ridge as shares surge over 63% in a single day, reflecting strong investor optimism and renewed institutional interest.

A single-day rise of more than 63% is significant for any listed mining company and highlights the market’s recognition of the strategic value created by FAST-41 inclusion. Resolution Minerals secures White House FAST-41 status for Antimony Ridge as shares surge over 63% in a single day because the milestone reduces development uncertainty.

Investors increasingly favor projects aligned with government-backed critical mineral strategies. Resolution Minerals secures White House FAST-41 status for Antimony Ridge as shares surge over 63% in a single day because the company is now better positioned to attract partnerships, funding, and development momentum.

Following the success that Resolution Minerals Advances Antimony Ridge Metallurgy with High-Purity Antimony Trioxide Production, the next steps are likely to focus on expanding metallurgical optimization, resource growth, feasibility studies, and project development planning.

Further test work may improve recovery rates, processing efficiency, and operating cost estimates. These improvements can significantly enhance project economics and strengthen financing opportunities for mine construction and downstream processing facilities.

Exploration activities may also continue to expand the overall resource base, increasing project scale and extending potential mine life. A larger and better-defined resource strengthens both operational flexibility and long-term strategic value.

A major step forward at Horse Heaven — Resolution Minerals has successfully produced 52.3% WO₃ tungsten concentrate from historical stockpiles, showcasing a clear pathway to near-term value.

🔍 Key Highlights

19x upgrade from ~1.85% WO₃ stockpile grades

Up to 75.5% recovery via simple gravity processing

Low-cost opportunity leveraging existing stockpiles at Johnson Creek

Further optimisation test work underway

13,700m drilling campaign kicking off at Golden Gate

💡 Big Picture Early-stage processing + strong recoveries = potential fast-track monetisation, while building a multi-commodity U.S. critical minerals platform.
