Resolution Minerals Targets Gold and Antimony with August Drilling at Horse Heaven

Strategic Location and Historical Significance

Resolution Minerals Ltd (ASX, RML) is advancing its critical metals ambitions with the imminent start of its maiden exploration program at the Horse Heaven Project in central Idaho, USA. This project is strategically positioned adjacent to Perpetua Resources’ Stibnite Gold Mine, a significant operation valued at approximately US$2.2 billion. The Horse Heaven Project lies within the historic Stibnite Mining District, an area with a legacy of antimony and tungsten production dating back to the early and mid-20th century.

Antimony, a metal critical for military and industrial applications, was produced here during both World Wars, underscoring the project’s potential strategic importance. Tungsten, another critical metal, was mined sporadically from the 1950s through the 1980s. Today, the United States has no domestic antimony production and relies entirely on imports, positioning Horse Heaven as a potentially vital source if development progresses.

Exploration Program and Objectives

The upcoming exploration campaign, set to commence immediately following final preparations, will focus on detailed surface mapping and sampling of two key mineralised fault zones, the Golden Gate Fault Zone and the Antimony Ridge Fault Zone. These zones have demonstrated significant gold, antimony, silver, and tungsten mineralisation in historical trenching and shallow drilling, but remain open-ended and underexplored at depth.

Resolution Minerals plans to use modern exploration techniques, including deeper reverse circulation and diamond core drilling, soil geochemistry, and geophysical surveys, to refine drill targets. The initial drill program is scheduled for August 2025, contingent on receiving permits from the United States Forest Service and completion of the project acquisition, expected after shareholder approval in late July.

Government Engagement and Funding Prospects

Recognising the strategic nature of the Horse Heaven Project, Resolution Minerals has begun engaging with US government agencies, including the Department of Defence, to explore potential funding grants and fast-track permitting processes. This proactive approach could provide critical support to accelerate exploration and development timelines, aligning with broader US interests in securing domestic sources of critical minerals.

Additionally, Resolution Minerals is progressing a listing on the US OTC market, which may enhance its profile and access to capital in North America.

Outlook and Investor Implications

The Horse Heaven Project represents a significant step in Resolution Minerals’ US-focused critical metals strategy. While historical data and proximity to a major mining operation provide a promising foundation, the company cautions that mineralisation similar to that at the adjacent Stibnite Gold Mine is not guaranteed. The forthcoming exploration results will be pivotal in defining the project’s resource potential and shaping its development pathway.

Investors will be watching closely as the company advances through its initial fieldwork, drilling, and government engagement phases, all of which will inform the project’s valuation and strategic positioning in the critical metals sector.
