Resolution Minerals Ltd (ASX: RML | OTCQB: RLMLF) (“Resolution Minerals” or “the Company”) has unveiled a major new gold discovery at its Golden Gate South Prospect within the 100%-owned Horse Heaven Gold–Antimony–Tungsten–Silver Project in Idaho, USA. Announced to the ASX on 9 February 2026, the results mark a decisive step-change for the Company, extending the Golden Gate mineralised system beyond 1.5 kilometres of strike length and confirming the presence of a second gold-bearing shear zone.
This discovery strengthens Horse Heaven’s status as a rapidly emerging multi-commodity district-scale project in a tier-one mining jurisdiction. Importantly, every drill hole reported in this phase of exploration ended in mineralisation, signalling substantial potential for further extensions both along strike and at depth.

RML’s CEO of US Operations, Craig Lindsay, has mentioned in this context:
“The discovery at Golden Gate South materially expands the Golden Gate gold system and confirms the presence of multiple mineralised shear zones over a substantial strike length.”
Golden Gate South: A Breakthrough in First-Pass Drilling
Golden Gate South lies approximately 600 metres south of the established Golden Gate North deposit. As part of its maiden 2025 drill program, the Company completed three diamond core holes at Golden Gate South, totalling 887 metres. Two of these holes delivered standout results that confirmed broad, near-surface gold mineralisation.
Major intercepts included:
- HH-GG25-009C: 172.2m @ 0.464 g/t Au, including 27.6m @ 0.89 g/t Au with a peak grade of 3.3 g/t over 1.5m.
- HH-GG25-010C: 225.5m @ 0.14 g/t Au from surface to end of hole.
- HH-GG25-008C: Anomalous gold throughout, ending in mineralisation grading 0.91 g/t Au.
Crucially, all three holes remained mineralised at their final depths, highlighting the likelihood that the system extends significantly deeper than current drilling has tested.

A Second Gold-Bearing Shear Zone: The Vibika Shear Zone
One of the most significant outcomes of the program is the identification of a second, parallel gold-bearing structure east of the main Golden Gate Shear Zone. Drilling at HH-GG25-009C intercepted mineralisation associated with what the Company has named the Vibika Shear Zone, a steep east-dipping sulphide-rich structure approximately 500 metres east of the primary shear zone hosting Golden Gate North.
Geological indicators suggest that the Vibika Shear Zone could extend over up to 3 kilometres of strike, based on rock chip sampling from historic Vibika adits and surrounding areas.
Gold mineralisation in this zone is associated with:
- Disseminated pyrite
- Quartz vein-hosted pyrite
- Arsenopyrite within altered monzonite and volcanic rocks
This mineral assemblage closely mirrors that seen at Golden Gate North, reinforcing the continuity of the broader Golden Gate system.
Multi-Commodity Upside: Tungsten and Silver in the Mix
Beyond gold, drilling at Golden Gate South also intersected multiple zones of shallow tungsten mineralisation in HH-GG25-010C. Three distinct tungsten-bearing veins were encountered, often associated with gold, silver, and antimony, although regional evidence suggests tungsten may represent a separate mineralising phase.
This adds a compelling multi-commodity dimension to the project, particularly given the proximity to the historic Golden Gate Tungsten Mine, which last operated in 1980.
Are Golden Gate North and South One Giant System?
With both Golden Gate North and Golden Gate South now defined over a combined 1.5-kilometre strike length, geologists are actively considering whether these two prospects form:
- A single continuous gold system,
- Two separate but parallel deposits, or
- Two systems offset by faulting along the Johnson Creek–Golden Gate Shear Zone.
While drilling between the two zones remains limited, the Company has identified strong geological similarities and structural alignment that suggest a potentially connected mineralised corridor.
Key observations supporting this view include:
- A shared gold–sulphide association dominated by pyrite and arsenopyrite.
- Both prospects occupying ridge-top positions connected by a prominent geological feature.
- A consistent northeast–southwest structural orientation controlling mineralisation.
Further drilling planned for 2026 aims to resolve this critical geological question.

Mineralisation could be continuous between Golden Gate North and South, two separate deposits, or parallel systems, possibly offset by faults. More drilling planned in the next field season will help determine the correct model. [Resolution Minerals]
What Comes Next? A Large-Scale 2026 Drill Program
Buoyed by the success of its maiden program, the Company is preparing for a significantly expanded drilling campaign beginning as early as May 2026. This program will focus on:
- Expanding gold discoveries at both Golden Gate North and Golden Gate South.
- Testing lateral repetitions of mineralisation across strike.
- Exploring tungsten targets near the historic Golden Gate Tungsten Mine.
- Drilling along the Golden Gate Fault, where soil sampling has identified tungsten anomalies.
All planned drilling will occur under existing permits, while the Company simultaneously pursues a new exploration permit to broaden its footprint and enable access via new and reopened roads.
Importantly, the Company also intends to commission a maiden JORC-compliant mineral resource estimate at Golden Gate North following completion of the 2026 drilling campaign.
Management’s View: A Transformational Discovery
RML’s CEO of US Operations, Craig Lindsay, underscored the significance of the results:
“With mineralisation open in all directions and drilling returning broad, near-surface intercepts, Golden Gate is rapidly emerging as a highly significant gold discovery. The interval lengths and grades on holes assayed to date, and the fact that mineralisation continues over such a long strike length, make us very excited to continue drilling here and target establishment of a maiden JORC compliant mineral resource.”
This sentiment reflects the broader strategic shift underway at Resolution Minerals, from early-stage explorer to a Company on the cusp of defining a major gold system.

Why Idaho Matters: A Tier-One Jurisdiction
Horse Heaven sits immediately adjacent to Perpetua Resources Corp’s Stibnite Gold Project, one of the most advanced gold developments in the United States. Idaho offers strong regulatory frameworks, established mining infrastructure, and a supportive environment for responsible resource development.
For Resolution Minerals, this location reduces geopolitical risk and enhances the project’s attractiveness to potential partners, investors, and future offtake discussions.

Why This Discovery Matters for the Company
This announcement represents more than just another drill result — it signals the transformation of Horse Heaven into a district-scale gold system with multi-commodity potential. Key implications include:
- Confirmation of a second major shear zone at Golden Gate.
- Expansion of mineralisation beyond 1.5km of strike.
- Strong potential for a future standalone gold resource.
- Increased likelihood of a multi-deposit mining hub.
- Enhanced attractiveness for institutional investors and potential strategic partners.
Investors Outlook
From an investment perspective, Resolution Minerals now stands at a pivotal moment in its growth cycle. The discovery at Golden Gate South significantly de-risks the Horse Heaven Project by demonstrating that Golden Gate is not a single isolated deposit but part of a much larger mineralised system.
In the near term, investors can expect:
- Continued positive drill news through 2026.
- Potential re-rating of the Company as it advances towards a maiden JORC resource.
- Increased trading volumes as institutional interest grows.
- Possible strategic partnerships or funding initiatives to accelerate development.
The 12.77% share price surge on the latest announcement highlights rising market confidence. With a market cap just above $107 million and a 12-month return of nearly 490%, Resolution Minerals has already delivered exceptional performance, yet the best may still lie ahead.
If upcoming drilling confirms continuity between Golden Gate North and South, the Company could be sitting on a genuinely large-scale gold system in a premier mining jurisdiction. For investors with a long-term horizon, Resolution Minerals offers a compelling blend of exploration upside, multi-commodity exposure, and jurisdictional security.
