Resolution Minerals has reported final assay results from its 2025 drilling campaign at the Golden Gate prospects in Idaho, revealing extensive near-surface gold mineralisation alongside significant tungsten intercepts. The findings confirm the potential for a large, open-ended gold-tungsten deposit, setting the stage for accelerated exploration in 2026.
- Final 2025 drill results confirm broad near-surface gold mineralisation
- Significant tungsten mineralisation identified, notably in hole HH-GG25-012R
- All drill holes intercepted gold, many ending in mineralisation indicating open-ended deposits
- Golden Gate North and South deposits remain open and potentially connected
- 2026 drilling program planned to define maiden resource and expand footprint
Resolution Minerals’ 2025 Drilling Campaign Completes with Strong Results
Resolution Minerals Ltd (ASX – RML) has released the final assay results from its 2025 drilling program at the Golden Gate North and South prospects, part of the Horse Heaven Project in Idaho, USA. The campaign has delivered broad zones of near-surface gold mineralisation across all holes, complemented by significant tungsten intercepts, particularly in reverse circulation hole HH-GG25-012R. These results reinforce the company’s view of Golden Gate as a district-scale discovery with substantial growth potential.
Highlights and Geological Context
The standout intercept in HH-GG25-012R included 21 metres at 0.06% tungsten, with an 8-metre section grading 0.14% tungsten, alongside a 99-metre interval averaging 0.23 grams per tonne gold starting from surface. Other holes, such as HH-GG25-013R and diamond core hole HH-GG25-006C, also returned extensive gold mineralisation, with some intervals exceeding 1 gram per tonne. Notably, many holes ended in mineralisation, suggesting the deposits remain open at depth and along strike.
Geologically, the mineralisation is hosted within sheared granitic rocks associated with the Golden Gate Fault Zone, consistent with an intrusive-related gold deposit model. The spatial association of gold and tungsten mineralisation with northeast-southwest faults aligns with the company’s exploration model and bears similarity to the adjacent Stibnite Gold Mine operated by Perpetua Resources.
Implications and Next Steps
The 2025 drilling has effectively confirmed two distinct gold deposits at Golden Gate North and South, with ongoing uncertainty whether these represent a continuous system or separate but parallel deposits. Resolution plans to address this in its 2026 drilling campaign, which will focus on delineating the size and shape of the deposits, testing along strike extensions, and exploring depth potential. The company also intends to file new operational plans to expand drilling access and infrastructure, facilitating a larger footprint for exploration.
Metallurgical testing is underway and will intensify in line with drilling milestones, a critical step toward assessing the economic viability of the mineralisation. The company’s leadership expressed strong optimism, highlighting the exceptional nature of the discoveries and the potential for significant resource growth.
Broader Significance for Investors and the Market
Resolution Minerals’ results add to a growing narrative of promising gold and tungsten exploration in Idaho, a region with established mining activity. The open-ended nature of the mineralisation and the dual commodity potential enhance the project’s attractiveness. However, tungsten assay results are pending re-analysis due to potential under-reporting, and the true continuity between the two deposits remains to be confirmed.
Overall, the company’s methodical approach, combining diamond core and reverse circulation drilling, hydrogeological studies, and detailed geological modelling, positions it well to advance toward a maiden resource estimate. Investors will be watching closely as Resolution accelerates its exploration efforts in 2026.
Bottom Line?
Resolution Minerals’ 2025 drilling results at Golden Gate lay a robust foundation for resource definition, but key questions on deposit continuity and tungsten grades remain to be resolved.
Questions in the middle?
- Will the 2026 drilling confirm whether Golden Gate North and South form a continuous deposit?
- How will the re-analysis of tungsten assays impact the reported grades and economic potential?
- What timeline and scale can investors expect for the maiden resource estimate and potential development?
