Drilling Permits Secured for Strategic Idaho Project Adjacent to $2 Billion Stibnite Gold Mine
Resolution Minerals (ASX: RML) has received final drilling permits for its Horse Heaven Antimony-Gold-Silver-Tungsten Project in Idaho, USA, paving the way for drilling campaign horse heaven resolution minerals to commence in August 2025. The U.S. Forest Service approval represents a significant milestone for the project, which is located directly adjacent to NASDAQ-listed Perpetua Resources' $2 billion Stibnite Gold Mine.
The permits allow for up to 57 holes from 19 drill sites along existing roads, with the Phase 1 program targeting up to 20 holes totaling approximately 20,000 feet at the Golden Gate target area. This marks the first new drilling at the project in over 30 years.
"The receipt of this approval to conduct drilling operations is transformational for the Horse Heaven Project," said Craig Lindsay, CEO of U.S. Operations. "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."
Golden Gate Ridge: A Target with Proven Gold Potential
The Golden Gate Fault Zone represents a significant exploration opportunity with:
- 3.5km strike length hosting disseminated gold mineralisation
- Historical drilling results showing substantial gold intercepts:
- GGR-31: 36.6m @ 1.51 g/t Au
- GGR-32: 71.6m @ 1.37 g/t Au
- GGR-33: 59.4m @ 1.03 g/t Au
- Established gold mineralisation in soils throughout the entire fault zone
What makes this target particularly compelling is that historical drilling only targeted shallow, oxide mineralisation, with all holes suspended at the oxide/sulphide boundary as previous companies were only looking for open-pit, heap leachable ore. No historic holes were longer than approximately 170 metres, and the true depth was much less as all holes were drilled at approximately 50 degrees.
| Historical Drill Hole | Intercept |
|---|---|
| GGR-31 | 36.6m @ 1.51 g/t Au |
| GGR-32 | 71.6m @ 1.37 g/t Au |
| GGR-33 | 59.4m @ 1.03 g/t Au |
Golden Gate Ridge currently represents a large, open-ended ore body that begins at surface and remains open in every direction. Historically, the area has produced tungsten from both open pits and underground adits, adding to the multi-commodity potential of the project.
Understanding Critical Minerals: Why Antimony Matters
Antimony is classified as a critical mineral by many governments including the United States, due to its strategic importance and supply risks. It has two primary applications that make it particularly valuable:
-
Flame retardants: Antimony trioxide is widely used in products requiring fire resistance, including electronics, textiles, and plastics.
-
Defence applications: Antimony is used in the production of ammunition, armor-piercing bullets, and other military equipment.
China currently dominates global antimony production, accounting for approximately 60% of world supply. This concentration creates significant supply chain vulnerabilities for Western nations, particularly the United States, which has designated antimony as a critical mineral essential to economic and national security.
The potential for domestic antimony production at the Horse Heaven Project could represent a strategic opportunity to reduce U.S. dependency on foreign sources of this critical metal. Resolution's drilling campaign horse heaven resolution minerals will include testing for antimony potential, as an antimony anomaly has been identified that runs parallel to the Golden Gate Fault Zone.
Acquisition Progress and Timeline
Resolution Minerals has made significant progress on its acquisition of the Horse Heaven Project. A key condition precedent has been completed, with the vendor (1503571 B.C) exercising its option to acquire 100% of 1262446 B.C. Ltd, the owner of the Horse Heaven Project.
The acquisition now awaits just two remaining conditions:
- Completion of due diligence by Resolution Minerals
- Shareholder approval at the upcoming General Meeting on July 25, 2025
Assuming these conditions are met, the Phase 1 drilling campaign horse heaven resolution minerals will commence in August 2025, with a potential Phase 2 program planned for Spring/Summer 2026, depending on initial results.
In preparation for the drilling campaign, Resolution is finalising agreements with drilling contractors and other service providers. The company has also initiated a mapping and sampling program at Golden Gate, Antimony Ridge, and other emerging exploration targets to assist with planning and permitting activities for future drilling.
The Strategic Value Proposition
The Horse Heaven Project represents a compelling opportunity for Resolution Minerals and its investors for several key reasons:
-
Strategic location: Adjacent to Perpetua Resources' $2 billion Stibnite Gold Mine, providing geological context and infrastructure advantages.
-
Critical mineral focus: The potential for antimony and tungsten production aligns with U.S. strategic priorities for domestic critical mineral supply.
-
Historical production: The Golden Gate Ridge area has historically produced tungsten from both open pits and underground adits.
-
Untested potential: Previous exploration only targeted shallow oxide gold, leaving the deeper sulphide mineralisation and critical mineral potential largely unexplored.
-
Existing infrastructure: The presence of existing roads allowing access to all planned drill sites reduces development costs and environmental impact.
"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," noted Craig Lindsay.
Why Investors Should Watch Resolution Minerals
Resolution Minerals is positioned at the intersection of several powerful market trends: critical minerals security, precious metals exploration, and U.S. domestic resource development. The Horse Heaven Project offers exposure to gold, antimony, silver, and tungsten in a tier-one mining jurisdiction.
With drilling permits now secured and the acquisition nearing completion, Resolution Minerals is approaching a period of potentially significant news flow as it undertakes the first modern exploration program at Horse Heaven in decades. The upcoming drilling campaign horse heaven resolution minerals will test both the confirmed gold mineralisation and the untapped potential for critical minerals at depth.
For investors interested in the critical minerals space, Resolution Minerals offers an opportunity to gain exposure to both precious metals and strategic resources in a project that could have national significance for U.S. mineral security.
The company has also announced that 12,500,000 fully paid ordinary shares, currently subject to voluntary escrow, will be released on 17 July 2025, ahead of the previously agreed release date of 21 September 2025. Additionally, 5,000,000 RMLOC quoted options subject to voluntary escrow will be released on 31 July 2025, and 81,963,480 RMLO options will expire on the same date.
Corporate Actions and Market Information
As part of its corporate activities, Resolution Minerals has disclosed several important updates for shareholders:
-
Escrow Release: 12,500,000 fully paid ordinary shares will be released from voluntary escrow on 17 July 2025, earlier than the previously scheduled release date of 21 September 2025.
-
Options Release and Expiry: 5,000,000 RMLOC quoted options will be released from voluntary escrow on 31 July 2025, while 81,963,480 RMLO options will expire on the same date.

Key Takeaway:
Resolution Minerals has secured drilling permits for its strategically located Horse Heaven Project in Idaho, with drilling set to commence in August following expected acquisition completion. With proven gold mineralisation at surface and untested potential for critical minerals including antimony and tungsten at depth, the project addresses both precious metals demand and U.S. critical mineral security priorities. The upcoming drilling campaign represents the first modern exploration of the property in over 30 years and could establish Resolution as a significant player in the U.S. domestic critical minerals sector.
