Adelaide, Australia – 17 February 2026
Resolution Minerals Ltd (ASX: RML) has confirmed further broad gold mineralisation and identified significant tungsten mineralisation from final assays of its 2025 drilling program at the Golden Gate North and Golden Gate South prospects within the Horse Heaven Project, Idaho, USA.
All holes completed in the 2025 campaign intersected gold mineralisation, with drilling confirming near surface continuity and open ended extensions along strike and at depth. The results further strengthen Golden Gate as an emerging district scale gold discovery with associated tungsten potential.
Key Highlights
• 99.1m at 0.38g/t Au from surface in RC hole HH-GG25-013R
• 103.5m at 0.37g/t Au from surface in diamond core hole HH-GG25-006C
• 133.7m at 0.55g/t Au including 15.6m at 1.10g/t Au
• 21m at 0.06% W including 8m at 0.14% W in HH-GG25-012R
• Gold mineralisation now defined over a 1,500m strike length and 300m width
• Mineralisation remains open in all directions
The tungsten intercept in HH-GG25-012R confirms extension of high grade mineralisation from historic mine workings to the north and introduces a meaningful polymetallic dimension to the Golden Gate system.
Drilling has identified two gold deposits within the Golden Gate Fault Zone, Golden Gate North and Golden Gate South. Ongoing work will determine whether these represent a continuous deposit, fault offset segments, or parallel systems.
Importantly, mineralisation across both prospects remains open along strike to the northeast and southwest, across strike, and at depth. The broader gold envelope is consistent with an intrusive related gold system model, comparable to mineralisation in the adjacent Stibnite Mining District.
Executive Comment
RML’s CEO of US Operations, Craig Lindsay, commented on the latest drilling results:
“The drilling accomplished at the Horse Heaven Project in our first season was exceptional. We have encountered gold discoveries at both the north and south ends of the Golden Gate Prospect, which is now emerging as a district-scale discovery. We are very excited about the potential to significantly grow both gold and tungsten mineralization. Golden Gate is only in early days and is emerging into what we feel is a very large gold deposit.
It is easy to conclude that the 2025 drilling campaign has resulted in a major gold discovery, currently open ended in all directions.
It is a gold discovery totally in keeping with the intrusive related, shear-hosted gold exploration model we have for the original Golden Gate Fault Zone, and it is a credit to our technical team for recognising such potential. The fast-approaching 2026 drilling campaign will seek to define a maiden resource at Golden Gate.”
2026 Program and Next Steps
The 2025 drill program is now complete with no assays pending.
The 2026 drilling campaign will focus on:
• Along strike extensions between Golden Gate North and Golden Gate South
• Northeast extensions from Golden Gate North
• Southwest extensions from Golden Gate South
• Depth extensions below current drilling
Resolution also plans to lodge a new Plan of Operations to significantly expand the drill footprint across the Golden Gate Fault Zone. Metallurgical testing is ongoing and will be accelerated alongside drilling milestones.
