Strategic Location with High-Grade Mineralisation

The Horse Heaven Project lies adjacent to one of the largest antimony-gold operations in the U.S., granting it logistical advantages and potential synergies. It covers a vast 5,644 hectares and includes two major geological fault zones—Antimony Ridge Fault Zone (ARFZ) and Golden Gate Fault Zone (GGFZ)—both of which are host to high-grade deposits of gold, antimony, silver, and tungsten.

Sampling and historical drilling have already highlighted significant grades. A standout rock chip sample from Antimony Ridge returned 3.68g/t gold, 303g/t silver, and 2.72% antimony over four metres. Further drilling, such as hole 87-GGR-31, delivered 85.34 metres at 0.937g/t gold, pointing to the potential for bulk tonnage extraction.

Historical Data Points to Exploration Upside

Resolution Minerals is preparing to drill test the project in 2025, focusing on verifying and expanding historical resource estimates. These include a non-JORC compliant estimate of 216,000 ounces of gold at Golden Gate Hill and another 70,000 ounces at Antimony Hill. The company aims to validate these figures through modern geophysics, soil sampling, and metallurgical assessments.

Notably, Horse Heaven has seen previous tungsten and gold production spanning from the 1950s through the 1980s, adding a layer of historical credibility and operational knowledge to its development potential.

Critical Minerals in Focus as Markets Shift

Antimony and tungsten are increasingly classified as essential to sectors such as aerospace, energy, and defence. The renewed interest in domestic critical mineral supply chains in the U.S.—especially under evolving geopolitical and policy climates—positions Resolution Minerals to benefit from these macro trends. This aligns with broader investor interest in diversified mining plays and adds a layer of resilience to portfolios seeking exposure to ASX dividend stocks.

Moreover, the move adds further relevance to Resolution Minerals within the ASX200 thematic, where resource-centric companies continue to play a pivotal role in Australia’s economic narrative.

Forward Plans and Capital Backing

The company has raised $1.9 million via placement to fund the acquisition and subsequent exploration. These funds will support early-stage work including detailed sampling and advanced drill planning across the ARFZ and GGFZ zones.

This initiative strengthens Resolution Minerals’ strategic footprint in the booming U.S. critical minerals market and adds meaningful depth to its evolving resource portfolio—highlighting its alignment with global trends in energy security and mineral independence.
