Inzinc Mining drills 3.2 m of 20.1% Zn at Indy

Executive Summary

• Inzinc Mining Ltd. reported exceptional high-grade zinc-lead-silver intersections from its Phase 2 2025 drill program at the Indy project in British Columbia, specifically in step-out hole IB25-043.
• The B-9 zone has been extended by 300 metres to the north, bringing the total strike length to over 1,000 metres, and remains open for expansion along strike and at depth.
• The company outlined its 2026 exploration plan, focusing on expanding the B-9 zone and initiating first-pass drilling on the "Delta" horizon, a new 1.4-kilometre-long target.

Key Details

• Primary Intersection (Hole IB25-043):
  • 20.1% Zn, 1.7% Pb, and 9.5 g/t Ag over 3.2 m from 197.6 m downhole.
  • Included in a wider zone grading 15.4% Zn, 1.3% Pb, and 7.2 g/t Ag over 4.2 m from 197.6 m downhole.
• Additional High-Grade Intervals in IB25-043:
  • 2.1% Zn, 3.5% Pb, and 15.0 g/t Ag over 1.9 m from 180.0 m downhole.
  • 11.6% Zn, 3.9% Pb, and 15.4 g/t Ag over 0.4 m from 185.1 m downhole.
  • 1.8% Zn, 0.4% Pb, and 2.1 g/t Ag over 2.7 m from 189.3 m downhole.
  • 1.4% Pb and 7.4 g/t Ag over 1.2 m from 192.4 m downhole.
• Zone Extension:
  • B-9 zone extended 300 m north, achieving a 125% strike extension to a total length of >1,000 m.
  • Mineralization remains open along strike and at depth.
• Phase 2 Drilling Summary:
  • Program included six holes totaling 800 m.
  • Holes IB25-041 and IB25-042 were completed on the same section as IB25-043; IB25-041 intersected a narrow 0.10 m zone of radiolarian-style sphalerite mineralization.
  • Hole IB25-042 had no mineralization.
  • Southern trend holes (IB25-040, IB25-044, IB25-045) encountered broken ground, lower-grade pyritic mineralization, and a significant fault zone offsetting the B-9 zone.
• Other Notable Intersections (Indy Project):
  • Hole IB25-029: 11.0% Zn, 2.3% Pb, and 27.1 g/t Ag over 3.0 m from 61.0 m downhole; contains gallium.
  • Hole IB25-029 Massive Sulphide: 0.6 m length grading 34.8% Zn, 7.0% Pb, and 76.7 g/t Ag returned 4.46 ppm gallium.
  • Hole IB25-032: 19.1 m intersection from 29.9 m downhole averaging 3.3% Zn, 0.7% Pb, and 7.4 g/t Ag, including a high-grade zone of 8.5% Zn, 2.1% Pb, and 21.3 g/t Ag over 2.0 m from 31.0 m downhole.
• 2026 Exploration Outlook:
  • Expansion and depth extension of the IB25-043 mineralized envelope.
  • Wide-spaced drilling to explore the >1,000 m B-9 strike to the north and at depth.
  • First exploration drilling of the "Delta" horizon, a 1.4 km long target with surface samples up to 25% barite and anomalous Zn/Pb/Ba.
• Project Context:
  • Indy project is 100% owned by Inzinc, located 90 km southeast of Prince George, BC.
  • Tenure covers 200 sq km over a 30 km unexplored trend.
  • Inzinc retains a 50% indium NSR royalty on American West Metals' West Desert project.

Notable Quotes

• "We are delighted with the success of the 300-metre stepout discovery in drill hole IB25-043. These are exceptional grades, comparable to top-quartile zinc-lead-silver deposits globally. The strike extent of B-9 zone mineralized system is now on scale with that associated with the large sedex [sedimentary exhalative] deposits in northwestern Canada. The Indy project is emerging as a tremendous new discovery opportunity in a premium location," remarked Wayne Hubert, chief executive officer of Inzinc.
