Irving Resources drills 26.38 m of 2.5 g/t Au at Omu

Executive Summary

• Irving Resources Inc. reports strong shallow gold-silver-silica drill results from its Omui and Omu Sinter targets within the Omu Gold-Silver Project in Hokkaido, Japan.
• The results define a north-south mineralized corridor at the Omui target, with all intercepts lying within 50 meters of surface, making them potentially amenable to small-scale open pit extraction for use as smelter flux.
• At the Omu Sinter target, a vertical drill hole confirmed a 41.81-meter thick high-silica intercept averaging 96.6% silica, 0.54 g/t Au, and 8.7 g/t Ag, situated just meters below the surface.

Key Details

• Omui Target (Low-Angle Drilling):

  • Four additional shallow holes were completed in 2025 following hole 24OMI-001 (101.1m @ 1.14 g/t Au, 16.0 g/t Ag, 84% silica).
  • All four new holes encountered broad, shallow mineralized intercepts.
  • Collectively, five shallow holes define a north-south mineralized corridor approximately 200 meters long, open to the north and south.
  • All mineralized intercepts lie within 50 meters of surface.
  • Hole 25OMI-002 encountered a high-grade zone: 2 meters wide showing 24.22 g/t Au and 173.40 g/t Ag.
  • Mineralization appears to be a broad, subhorizontal zone of silicification and mineralization.
  • Silica content is high (typically 80-90%), suitable for smelter flux.
  • Irving and partner JX Advanced Metals Corp. are discussing next steps to advance Omui as a source of smelter flux in Japan.

• Omu Sinter Target (Vertical Drilling):

  • Hole 25OMS-001 yielded a 41.81-meter thick high-silica gold-silver intercept.
  • Average grades: 96.6% silica, 0.54 g/t Au, and 8.7 g/t Ag.
  • The horizon is shallow, lying just a couple of meters below the surface, ideal for potential small-scale open pit extraction.
  • True width is approximately 100% of the drill width due to the horizontal orientation of the horizon.
  • Water table observed at 30 meters (9 meters above sea level); aquifer interpreted at the basal fractured zone.
  • Additional drilling is underway to test groundwater, continuity, and extensions.

• Technical & Operational Context:

  • Goal: Discover shallow, silica-rich gold-silver mineralization suitable for use as smelter flux.
  • Samples analyzed by ALS Global (Perth, Australia) using fire assay with AA finish (gravimetric for overlimit) and mass spectrometry for multielements.
  • Dr. Quinton Hennigh is the Qualified Person under NI 43-101.

Notable Quotes

• "We are very pleased to see expansive, shallow deposits of gold-silver-bearing silica emerge at both Omui and Omu Sinter," commented Dr. Quinton Hennigh, director and technical adviser to Irving. "At Omu, our goal is to find deposits that will prove suitable for use as sources of smelter flux within the Japanese base metal smelting industry. Our recent drill results indicate we are headed in the right direction. We look forward to working with our partner, JX, in further advancing work at the Omu project to achieve this mission."
