STUHINI HIGHLIGHTS HIGH-GRADE TUNGSTEN POTENTIAL AT RUBY CREEK

Stuhini Exploration Ltd. has released the results of a comprehensive review of tungsten mineralization at its 100-per-cent-owned Ruby Creek project located near Atlin, B.C. The review confirms the presence of a high-grade, structurally controlled tungsten system that flanks the company's existing 433-million-pound pit-constrained molybdenum deposit.

Meredith Eades, president and chief executive officer of Stuhini, commented: "Tungsten is increasingly recognized as a strategic metal, essential to both industrial applications and national defence. Our review of the Ruby Creek data set has confirmed a robust and high-grade tungsten system flanking our existing molybdenum deposit -- an opportunity that's been largely overlooked until now. As we continue our systematic approach to exploration, these results add a new layer of value to Ruby Creek and reinforce our commitment to advancing critical mineral assets that align with future demand."

Key highlights

• 188 rock samples returning greater than 0.1 per cent WO3 (tungsten trioxide), including 40 samples greater than 1 per cent WO3 and three samples greater than 10 per cent WO3;
• Tungsten-bearing structures mapped along multiple faults, shears and veins up to 1.75 metres wide and over 2.9 kilometres in strike;
• Drill-ready potential supported by historic drill intercepts of:
  • 0.15 per cent WO3 over 27.43 m (GD17-003B), including 0.76 per cent over 3.05 m;
  • 0.14 per cent WO3 over 18.29 (GD17-007), including 0.63 per cent over 3.05 m.
• Channel sampling results from Thor Ridge rrend include:
  • 1.35 per cent WO3 over 1.75 m, including 2.19 per cent WO3 over one m;
  • Associated gold-silver-copper values: up to 9.27 g/t Au (gold), 225 g/t Ag (silver) and 0.30 per cent Cu (copper).

Tungsten system overview

Mapping and sampling at Ruby Creek have outlined multiple tungsten-bearing structures forming a broad halo around the Ruby Creek molybdenum deposit. These mineralized structures are associated with northeast-southwest-trending faults, veins and shear zones that range from 0.1 to 1.75 metres thick and extend for hundreds to thousands of metres along strike. Primary tungsten minerals identified include wolframite and scheelite.

A total of 188 samples returned greater than 0.1 per cent WO3, with 40 samples exceeding 1 per cent WO3 and three returning over 10 per cent. These values occur along well-defined trends, suggesting strong structural control and continuity of mineralization.

Multiple tungsten-bearing trends surround the Ruby Creek molybdenum deposit, with samples returning greater than 10 per cent WO3 along several faults and splays.

Rock samples show a defined tungsten enrichment halo surrounding the Ruby Creek Mo deposit, with 188 samples greater than 0.1 per cent WO3 and 40 samples greater than 1 per cent WO3.

Target zones and historical work

Stuhini's internal review has outlined seven priority tungsten zones with strike extents from 750 metres to 4.5 kilometres.

In addition, anomalous tungsten in soils (20 to 500 ppm (parts per million)) suggests further mineralized structures may be present under till and soil cover along strike.

Next steps

Stuhini plans to follow up with detailed surface mapping and rock sampling to refine targeting across these structures and potentially identify new tungsten-bearing zones. The tungsten system represents a previously underappreciated critical minerals component of the Ruby Creek project and will be incorporated into future targeting and project advancement plans.

About the Ruby Creek project

The 29,734-hectare Ruby Creek project is located approximately 14 kilometres east of Atlin, B.C., and is road accessible. The property hosts the Ruby Creek molybdenum deposit, which contains a measured and indicated pit-constrained resource of 433 million pounds of molybdenum (using $15 (U.S.)/lb Mo and a 0.02-per-cent cut-off) and multiple additional mineral occurrences including gold, silver, tungsten and copper. Stuhini owns 100 per cent of the Ruby Creek project, subject to a 1-per-cent NSR (net smelter return).
