Yukon Metals Intersects 11.7 g/t Gold Within Extensive Vein System in First Drill Program and Expands Land Package at Star River Property

Executive Summary

• Yukon Metals reported results from its 2025 diamond drilling program at the Star River property, highlighting a high‑grade intercept of 11.7 g/t Au over 0.5 m and significant polymetallic mineralization (up to 183 g/t Ag, 10.6 % Pb, 3 % Zn).
• The drill campaign confirmed extension of the F2, F3 and Saddle vein corridors and supported acquisition of an additional 2 km of Stump claims along the same structural corridor.
• Company plans to integrate geological, geochemical and geophysical data to refine the structural model and target further vein splays in the F2 corridor.

Key Details

• Gold Intercepts:
• 11.7 g/t Au over 0.5 m (hole SR25‑001, 99.1–99.6 m).

• Multiple holes returned 0.2–4.9 g/t Au across the F2 zone.

• Silver‑Lead‑Zinc Intercepts:

• Up to 183 g/t Ag, 10.6 % Pb (hole SR25‑001, 28.5–29.0 m).
• Additional high‑grade silver hits: 116 g/t Ag (SR25‑007), 80 g/t Ag (SR25‑008).

• Zinc intervals up to 3.4 % Zn (hole SR25‑006).

• Drill Hole Summary (selected):

• Structural Context:
• Drone magnetic survey delineated a ~1 km east‑west trending low‑magnetic corridor coincident with F2, F3 and Saddle zones.

• Geophysical data (EM, gravity) support presence of graphitic schist and lead‑bearing alteration within the corridor.

• Land Expansion:

• Acquired contiguous Stump claims (~2 km of additional prospective ground) extending the structural corridor southward.

• Historical trenching on Stump claims showed surface samples > 2,400 g/t Ag and ~70 % Pb over narrow intervals.

• QA/QC:

• 10 % control samples; certified standards, blanks, duplicates used.

• Core split: one half for analysis (MSA), other retained for reference.

• Next Steps:

• Integrate drilling, geochemical and geophysical data to refine F2 structural model.
• Prioritize testing of additional vein splays where calcium‑rich metasedimentary units intersect the corridor.
• Focus future work on the newly acquired Stump vein target.

Notable Quotes

• “Results from our first drill program at Star River represent an important step toward defining a district‑scale polymetallic vein system… up to 11.7 g/t gold in vein material and intersected silver‑lead mineralization consistent with the surface vein exposures.” – Jim Coates, President & CEO

Materiality Assessment: Material – Positive (high‑grade gold and significant polymetallic intercepts, land acquisition expanding the target area).
