STUHINI ANNOUNCES STRATEGIC REFOCUS ON RUBY CREEK AMID GROWING DEMAND FOR PRECIOUS AND CRITICAL METALS

Stuhini Exploration Ltd. has a renewed and sharpened focus on its wholly owned flagship Ruby Creek project, located near Atlin, B.C., following a comprehensive strategic review of its project portfolio.

Meredith Eades, president and chief executive officer of Stuhini, commented: "As global demand for precious and critical minerals continues to grow, driven by macroeconomic uncertainty, industrial growth and supply concerns, we believe Ruby Creek is uniquely positioned with its combination of scale, access and diverse metal mix. Our focus is to unlock that value through methodical, data-driven work that prioritizes the strongest targets. With this year's program, we're laying the technical groundwork for what we believe could become a meaningful multizone drill campaign in 2026."

Key highlights of the Ruby Creek project

• Significant land package: approximately 29,734 hectares with seven distinct mineralized zones;
• Polymetallic potential: gold, silver, molybdenum and tungsten across multiple mineralization styles;
• Atlin gold: Atlin is recognized as a significant placer gold producing district. Suhini's mineral tenures underlay six of the nine main placer gold producing creeks;
• Established surface mineralization: 148 rock samples over 1.0 gram per tonne gold and 286 rock samples over 100 grams per tonne silver across a 15-kilometre corridor;
• Current updated (2022) National Instrument 43-101 molybdenum resource: includes multiple intervals grading over 1 per cent Mo (molybdenum);
• Tungsten upside: past-producing Black Diamond tungsten mine located on Stuhini tenures along with multiple other early stage tungsten targets;
• Underexplored targets: multiple zones remain open at depth and along key structures;
• Excellent infrastructure: road-accessible, approximately 15 km from Atlin, B.C., with extensive historical data.

Surface rock sampling across the property has returned gold assays up to 121.34 g/t Au and 14,179 g/t Ag with multiple clusters of high-grade samples distributed across several target zones.

Precious metals potential

Ruby Creek is host to a series of gold-bearing quartz veins across several structural zones, with rock sampling returning grades up to 121.34 g/t gold, while silver mineralization is widespread, with assays up to 14,179 g/t silver. These zones demonstrate strong near-surface potential and are supported by historical geochemical trends and structural continuity, yet many remain for the most part untested by modern exploration techniques.

Base metals and critical minerals

Ruby Creek hosts a porphyry-style molybdenum deposit, with a pit-constrained measured and indicated resource (March, 2022) of 432.99 million pounds Mo within 369.4 million tonnes grading 0.053 per cent Mo (0.020 per cent cut-off), and an inferred resource of 43.65 million lb Mo within 41.95 million tonnes grading 0.047 per cent Mo. Drilling includes multiple high-grade intervals exceeding 1 per cent Mo, up to 3.8 per cent. Early stage tungsten mineralization has also been identified, providing additional exposure to a metal increasingly recognized as critical for industrial, defence and energy applications.

Technical review and 2025 exploration plans

Stuhini has completed a full review of historical exploration at Ruby Creek, incorporating rock and soil geochemistry, geophysical surveys, and drill data. This comprehensive data integration has allowed the team to reprocess legacy geophysical data sets, rank existing targets based on geological merit, structural controls, and accessibility, re-examine and identify multiple zones with high discovery potential that have seen limited modern exploration to date.

Building on this foundation, Stuhini's 2025 program will focus on:

• Geological mapping and geochemical sampling across high-priority target zones;
• Ground-based geophysics, including ground magnetics and VLF surveys;
• Channel sampling and trenching to refine structural models and prioritize drill targets.

Building toward discovery

With scale, mineral diversity, historical data and multiple open targets, Ruby Creek represents a rare opportunity for significant value creation. The 2025 program is designed to systematically advance multiple zones toward drill readiness, with the objective of initiating a multizone drill campaign in 2026.

Ruby Creek offers exposure to a diverse suite of highly sought-after commodities, including gold, silver, molybdenum and tungsten -- all within a large-scale, road-accessible project in a proven mining jurisdiction. As part of this strategic refocus, Stuhini has relinquished its non-core Red Hills and Jersey Valley projects in Nevada, allowing exploration capital and technical efforts to be fully concentrated on advancing Ruby Creek.
