Extended Drill Program and Land Expansion Heighten Stakes at Horse Heaven
Resolution Minerals has secured US Forest Service approval to extend and expand its drilling program at the Horse Heaven project in Idaho, doubling planned holes and increasing land holdings by 600 acres.
- Phase 1 drill program extended by one month to end of October 2025
- Drilling increased from 8-10 to 18-20 holes, totaling approximately 18,000 feet
- Transition from core drilling to reverse circulation (RC) drilling starting October 1
- Land package expanded by 600 acres to 59 square kilometers
- Aim to generate data for initial mineral resource estimate and future exploration
Extension and Expansion Approved
Resolution Minerals Ltd (ASX – RML) has received a significant boost for its Horse Heaven Gold-Antimony-Tungsten-Silver Project in Idaho, USA, with the US Forest Service granting an amendment to extend the current Phase 1 drilling program by approximately one month. This extension allows the company to double its planned drill holes from 8-10 to 18-20, increasing the total drilling footage to around 18,000 feet. The move reflects encouraging early results from the Golden Gate Target, which have prompted Resolution to accelerate and broaden its exploration efforts.
Shift to Reverse Circulation Drilling
While the initial drilling phase has been conducted using diamond core rigs, Resolution plans to switch to reverse circulation (RC) drilling starting October 1, 2025. The RC method, known for its efficiency and cost-effectiveness, will enable the company to conduct additional infill and step-out drilling. This approach is designed to generate a richer dataset that could support an initial mineral resource estimate and inform the next phase of exploration and permitting activities.
Strategic Land Acquisition
In parallel with the drilling expansion, Resolution has increased its land holdings at Horse Heaven by 600 acres through the acquisition of 30 federal lode mining claims. This expansion brings the total project area to approximately 59 square kilometers, reinforcing the company’s commitment to a district-scale exploration program. The newly acquired ground is expected to host additional mineralisation potential and will be the focus of early-stage fieldwork this fall.
Context Within a Growing Mining District
The Horse Heaven Project sits within the historic Yellow Pine Mining District, adjacent to the fully permitted Stibnite Gold Project operated by Perpetua Resources Corp. This proximity adds strategic value to Resolution’s holdings, as the region gains increasing attention for its polymetallic mineral potential. The expanded drilling and land package position Resolution to capitalize on this momentum and potentially define a significant resource base.
Looking Ahead
Resolution’s CEO of US Operations, Craig Lindsay, highlighted the importance of the amendment, noting that the extended drilling and larger land footprint will provide a substantially higher volume of data to guide future exploration and resource estimation. Assay results from the initial core holes are expected within weeks, which will be closely watched by investors and analysts eager to assess the project’s economic prospects. Meanwhile, ongoing programs including stream sediment sampling and geological mapping will complement the drilling campaign.
Bottom Line?
With drilling doubled and land expanded, Resolution is poised to unlock new insights at Horse Heaven, setting the stage for a pivotal resource update.
Questions in the middle?
- What will the initial assay results reveal about the grade and extent of mineralisation at Golden Gate?
- How will the transition to reverse circulation drilling impact the quality and speed of data collection?
- Could the expanded land package uncover new targets that significantly enhance the project’s value?
