Resolution Minerals Doubles Drill Program at Horse Heaven After Promising Results
Resolution Minerals has significantly expanded its drilling activities at the Horse Heaven Gold-Antimony-Tungsten-Silver Project in Idaho, doubling the planned program and extending the drill season following encouraging early results.
Expanded Drilling Campaign to Accelerate Project Development
Resolution Minerals (ASX: RML; OTCQB: RLMLF) has received approval from the US Forest Service to extend its drilling season at Horse Heaven beyond the planned September 30 end date. This amendment allows the company to continue operations through October 2025, effectively doubling the Phase 1 drill program from 8-10 holes to 18-20 holes, with total drilling increasing from 9,000ft to 18,000ft (5,490m).
The expanded program will transition from diamond core drilling to reverse circulation (RC) drilling starting October 1, with an MP1500 RC drill rig already secured and scheduled to arrive on site. This strategic shift enables Resolution to conduct additional infill and step-out drilling to generate sufficient data for a potential initial mineral resource estimate.
"This Amendment is a significant development for Resolution and its shareholders," said Craig Lindsay, CEO of US Operations. "We have now secured a material extension of our Phase 1 drill program, including more metres and more holes, and increased our land package to cover additional areas of potential mineralisation."
Strategic Land Acquisition Expands Project Footprint
In a parallel move to strengthen its position in the region, Resolution has expanded its land holdings by 600 acres through the acquisition of 30 federal lode mining claims. This strategic addition increases the Horse Heaven Project's total area to 14,580 acres (approximately 59km²), enhancing the company's exploration potential in the historic Yellow Pine Mining District.
The newly acquired land will be subject to early-stage field programs this fall, as the company identified these areas as having potential to host valuable mineralisation. The expansion comes amid increasing interest in the district, partly driven by the ongoing development of the adjacent Stibnite Gold Project operated by Perpetua Resources Corp.
Current Drilling Progress Shows Efficiency
Resolution has made significant progress with its drilling program, currently on its 9th core hole with 7,320ft (2,231m) of drilling completed to date. The drilling contractor, Evolve Exploration Inc., is operating efficiently and is on track to complete approximately 9,000ft (2,740m) of drilling by September 30, 2025.
Three holes have already been submitted for assay, with initial results expected within the next four weeks. These results will provide valuable insights into the mineral potential of the Golden Gate Target, one of two major antimony-gold-silver-tungsten targets at Horse Heaven.
Understanding RC Drilling: A Cost-Effective Exploration Technique
For investors new to mining exploration, Reverse Circulation (RC) drilling represents an important advancement in the company's exploration strategy. RC drilling is a faster and more cost-effective method compared to diamond core drilling, making it ideal for the expanded program.
RC drilling uses compressed air to drive a rotating hammer bit, creating rock chips that are blown up through the centre of the drill rods to the surface for collection and analysis. While it doesn't provide the detailed geological information of core drilling, it allows for rapid testing of larger areas at lower cost. This makes it particularly valuable for infill drilling and extending known mineralisation zones – precisely what Resolution aims to accomplish in this expanded program.
The transition from core to RC drilling signals that Resolution has gathered enough detailed geological information from its initial core holes and is now focusing on expanding the known mineralisation footprint efficiently.
Project Timeline and Next Steps
With the expanded drilling program now underway, Resolution is implementing a multi-pronged exploration approach that includes:
- Continuation of core drilling through September 30, 2025
- Transition to RC drilling from October 1, 2025
- Ongoing stream sediment sampling programs
- Continued geological mapping and rock chip sampling
The company plans to release drilling results as they become available, with the first batch expected within the next month. The expanded dataset will be crucial for guiding next season's exploration program, supporting potential resource estimates, and informing future permitting applications.
Investment Potential in a Strategic Metals Project
The Horse Heaven Project represents a compelling investment opportunity in the growing critical minerals sector. The project targets a suite of metals with significant strategic importance:
- Gold: A traditional safe-haven investment and store of value
- Antimony: A critical mineral used in flame retardants, batteries, and defence applications
- Tungsten: Essential for hardened steel, electronics, and aerospace applications
- Silver: Used in industrial applications, renewable energy, and as a precious metal
The project's location in Idaho, a mining-friendly jurisdiction within the United States, adds strategic value at a time when secure supply chains for critical minerals are increasingly prioritised by governments and industries.
Horse Heaven's proximity to Perpetua Resources' Stibnite Gold Project (just 6km away) provides geological context and development synergies that could enhance the project's long-term potential.
Why Investors Should Track Resolution Minerals
Resolution Minerals presents a compelling opportunity for investors interested in the critical minerals and precious metals space for several key reasons:
-
The company is aggressively expanding both its drilling program and land package at Horse Heaven, demonstrating confidence in the project's potential.
-
The transition to RC drilling indicates a strategic progression from initial exploration to more systematic resource definition.
-
The project targets a diverse suite of metals with both precious metal value (gold, silver) and critical mineral applications (antimony, tungsten).
-
Early drilling results have been sufficiently encouraging to warrant doubling the current program.
-
The company operates in a mining-friendly jurisdiction with established infrastructure.
With assay results from the first holes expected within weeks and an expanded drilling program now underway, Resolution Minerals is approaching several potential value-driving catalysts that could significantly impact the company's trajectory in the coming months.
