Resolution Minerals Ltd (ASX:RML) is set to launch a maiden exploration campaign at the Horse Heaven Antimony-Gold-Silver-Tungsten Project, located in Idaho’s historic Yellow Pine Mining District. The field program is expected to begin in early July 2025, with the primary objective of defining the extent of previously identified surface mineralisation and generating drill targets ahead of a planned drilling campaign in August.

Program Objectives and Scope
The initial exploration campaign will include extensive mapping and sampling across several high-priority zones, particularly the Golden Gate Fault and Antimony Hill Fault zones, which remain open ended. Additional activities will target the Vibeka Creek area, located adjacent to Golden Gate, where surface anomalies have been historically noted but not extensively explored.
Key aims of the program include:
- Identifying extensions of mineralisation along the Golden Gate Fault to the north and south of historical drill zones and expanding geological understanding.
- Targeting future drill sites and improving geological knowledge at Antimony Creek.
- Finalising drill sites for the August drilling program and assessing additional locations for future exploration campaigns.
- Supporting the design of a geophysical program and refining drill targeting.
Strategic Significance of Horse Heaven
RML inked an agreement to acquire the Horse Heaven Project earlier this year. As a sign of commitment to the asset, the company has commenced preparatory exploration activities ahead of the formal completion of the acquisition, expected in late July 2025 following the shareholder meeting on 25 July.
Historically, antimony was mined at Horse Heaven during World War I and II, while tungsten was intermittently produced between the 1950s and 1980s. The U.S. is currently 100% reliant on imported antimony, positioning the project to potentially address the antimony supply shortage in long term if progressed through to production.
Next Steps and Long-Term Vision
The company aims to significantly expand the project's resource potential by applying modern exploration techniques.
RML has also initiated discussions with U.S. federal agencies to explore opportunities for funding and permitting acceleration, including potential support from the Department of Defence.
Additionally, the company is progressing towards a U.S. OTC listing, with further updates expected in the near term.
RML shares were trading 3.77% higher at AUD 0.055 per share at the time of writing on 3 July 2025.
