9 July 2025 – Sydney, Australia | Resolution Minerals is pleased to announce it has received final approval from the U.S. Forest Service for drilling at its Horse Heaven Antimony-Gold-Silver-Tungsten Project in Idaho, USA. This significant milestone clears the way for a Phase 1 drilling campaign that is expected to begin in August 2025 (following completion of the project acquisition).
Highlights:
-
Final drilling permits granted by U.S. Forest Service for Horse Heaven Project in Idaho, USA
-
Phase 1 drilling to commence August 2025, following completion of the project acquisition
-
Permits cover up to 57 drill holes from 19 sites; initial program to include ~20,000 feet of drilling
-
Phase 1 to target the Golden Gate Fault Zone, a 3.5km strike with established gold mineralisation
-
Historic RC drilling returned strong gold intercepts, with potential for antimony and tungsten also identified
-
Acquisition milestone met as vendor exercises option over the project-holding entity
The Phase 1 program will include up to 20 drill holes totalling approximately 20,000 feet, with a focus on the Golden Gate target area. The permits allow for a broader program of up to 57 holes from 19 drill sites along existing roads.
Located adjacent to NASDAQ-listed Perpetua Resources’ Stibnite Gold Project, the Golden Gate Fault Zone extends approximately 3.5km and hosts known gold mineralisation. Historical reverse circulation drilling from 1986 to 1994 reported encouraging intercepts, including:
-
36.6m @ 1.51g/t Au (GGR-31)
-
71.6m @ 1.37g/t Au (GGR-32)
-
59.4m @ 1.03g/t Au (GGR-33)
All historical drilling was shallow and terminated at the oxide/sulphide boundary. The upcoming campaign will be the first to test deeper mineralisation for gold, antimony, and tungsten.
Craig Lindsay, CEO of U.S. Operations, commented: “The receipt of this approval to conduct drilling operations is transformational for the Horse Heaven Project, and allows for the first new drilling at the project in over thirty years. Resolution Minerals is very excited to begin aggressively advancing Horse Heaven, to confirm the presence of a gold resource at Golden Gate, expand known mineralisation and potentially identifying the presence of tungsten and antimony.
Historically, the Golden Gate Ridge area has produced tungsten from both open pits and underground adits, and an antimony anomaly has been identified that runs parallel to the Golden Fault Zone. We are excited about the prospect of the Horse Heaven Project and its potential to play an important role in meeting the United States’ growing demand for a domestic supply of critical metals.”
In parallel, the Company confirms that a key acquisition milestone has been met, with the vendor 1503571 B.C. completing the acquisition of 100% of the share capital in the project-holding entity. Completion of Resolution Minerals’ acquisition remains subject to due diligence and shareholder approval at the upcoming meeting scheduled for 25 July 2025.
The Company also provided updates on escrow releases and option expiries, noting that 12.5 million shares will be released from escrow on 17 July 2025, and 5 million options on 31 July 2025. An additional 81.96 million RMLO options are also due to expire on 31 July 2025.
