Resolution Minerals Expands Golden Gate Drilling Campaign Following Success

The Resolution Minerals Golden Gate drilling campaign represents a pivotal moment for the company as it scales up operations following exceptional Phase 1 results. Resolution Minerals (ASX: RML; OTCQB: RLMLF) has announced a substantial Phase 2 drilling program at its Golden Gate fault zone within the Horse Heaven Gold-Antimony-Tungsten-Silver Project in Idaho, USA. The 45,000-foot (13,700-metre) program across up to 45 diamond holes represents a significant expansion following the company's successful 2025 drilling campaign where all holes intersected gold mineralisation and remain open at depth.

The program is designed to define the scale of gold mineralisation at Golden Gate and Golden Gate South zones, supporting progression toward a maiden Mineral Resource Estimate targeted for Q1 2027. With two MP1500 Core diamond drill rigs set to commence operations in early May 2026, Resolution is positioning itself to unlock the full potential of what appears to be a large, continuous gold mineralised system.

Outstanding Phase 1 Results Drive Expanded Drilling Program

The success of Resolution's 2025 drilling campaign has provided the foundation for this ambitious Phase 2 program. The Phase 1 campaign, totalling 10,100 feet (3,780 metres) across 14 holes, delivered impressive results that have clearly demonstrated the potential scale of the Golden Gate system.

Key Phase 1 Intercepts Include:

What makes these results particularly compelling is that all Phase 1 drill holes intersected gold mineralisation from surface and remain open at depth, indicating the system's potential for significant expansion through deeper drilling.

CEO Craig Lindsay commented: "Following our impressive 2025 drill campaign, it is clear that Golden Gate hosts a large continuous gold mineralised system, with all holes intersecting mineralisation and remaining open at depth. The upcoming drill program is designed to define the size and shape of this system, and to advance Golden Gate toward a maiden JORC-compliant Mineral Resource Estimate."

Strategic Phase 2 Program Design Targets System Scale

The Resolution Minerals Golden Gate drilling campaign Phase 2 program has been strategically designed to test both the Golden Gate North and Golden Gate South targets, with drilling allocation planned at approximately 60% Golden Gate South and 40% Golden Gate North. This allocation reflects the emerging discovery potential at Golden Gate South while continuing to expand the established mineralisation at Golden Gate North.

Golden Gate North Expansion

At Golden Gate North, the program will combine infill and step-out drilling to expand known mineralisation. The standout intercept from hole HH-GG25-001C provides a compelling target for follow-up:

• 189.2m @ 1.30 g/t Au from 34.1m to 223.4m, ending in mineralisation
  • Including 12.9m @ 2.32 g/t Au from 94.4m
  • Including 29.6m @ 2.71 g/t Au from 131.8m
  • Including 70.8m @ 2.24 g/t Au from 128.8m

Multi-Commodity Potential Emerges

The program has also identified significant tungsten mineralisation, confirming the project's multi-commodity potential. Furthermore, hole HH-GG25-012R intersected 21m @ 0.06% W, including 8m @ 0.14% W, with additional anomalous tungsten intervals recorded. This tungsten mineralisation extends from the historical Golden Gate Tungsten Mine workings, adding another value driver to the project.

Golden Gate South Discovery Zone

The Golden Gate South target represents an emerging discovery following results from hole HH-GG25-013R, which returned 99.1m @ 0.38g/t Au from surface to end of hole, ending in mineralisation. This confirms near-surface oxidised gold mineralisation extending east of the 2025 drilling areas, expanding the system across Golden Gate Hill.

Understanding Intrusive-Related Gold Systems

For investors new to mining terminology, Intrusive-Related Gold (IRG) deposits represent a specific type of gold mineralisation that forms when gold-bearing fluids are associated with granitic intrusions. These systems are characterised by their large size, relatively consistent grades, and potential for bulk mining operations.

IRG deposits typically feature:

• Large tonnage potential with consistent grade distribution
• Multiple commodity association (gold with tungsten, antimony, silver)
• Structural control through fault systems that channel mineralising fluids
• Near-surface oxidation that can enhance processing characteristics

The geological setting at Golden Gate shares similarities with the nearby Perpetua Resources' Stibnite Gold Mine, providing a valuable benchmark for the system's potential scale and economic viability. Resolution interprets the gold mineralisation at Golden Gate North and Golden Gate South to represent a sheared granite-hosted, fault-controlled disseminated Au-[Ag-W] IRG deposit.

Comprehensive 2026 Field Program Timeline

Resolution has developed a systematic approach to the 2026 field season, with activities planned to deliver a steady flow of results. In addition, the comprehensive timing ensures optimal resource allocation throughout the program duration.

Program Timeline:

• Early May 2026: Drilling commencement (weather dependent)
• May-August 2026: Continuous drilling operations
• Ongoing: Geological logging, sampling, and assay results
• Progressive: Step-out and follow-up drilling based on results

Drilling Objectives:

1. Strike extensions testing north, south, and between zones
2. Depth extensions below existing drilling
3. Infill drilling to define grade continuity
4. Step-out drilling to expand known mineralisation boundaries

The company has engaged Evolve Exploration Inc. to execute the program using two MP1500 core diamond drill rigs, with no Reverse Circulation drilling planned.
