Inzinc Mining to begin phase 2 drilling at Indy

Executive Summary

• Inzinc Mining Ltd. announces a Phase 2 diamond drill program (7–10 holes) to begin around Sept. 11, 2025, targeting northern and southern extensions of the B‑9 mineralized trend at its 100 % owned Indy Sedex project in central British Columbia.
• Phase 1 drilling (11 holes, 1,089 m) extended the near‑surface B‑9 zinc‑lead‑silver‑barite trend to >700 m length and intersected multiple high‑grade massive sulphide zones, including a 3.0 m interval averaging 11.0 % Zn, 2.3 % Pb and 27.1 g/t Ag.
• The B‑9 trend remains open both laterally (≥750 m of untested soil geochemical/EM anomalies to the north) and at depth; only ~10 % of the 7.5 km main trend has been tested to date.

Key Details

• Phase 2 Drill Program
• Planned start: on or about Sept. 11, 2025.

• Scope: 7–10 additional drill holes to test northern and southern extensions of B‑9.

• Phase 1 Highlights

• Total drilling: 11 holes, 1,089 m; extended B‑9 trend from 450 m to >700 m length (≈40 % increase).
• All holes intersected mineralization at the principal horizon; 9 holes exceeded cut‑off (>1 % Zn over ≥2 m).
• Hole IB25‑029 – 3.0 m @ 11.0 % Zn, 2.3 % Pb, 27.1 g/t Ag from 61.0 m depth; also contained gallium (critical mineral).
• Hole IB25‑032 – 19.1 m @ 3.3 % Zn, 0.7 % Pb, 7.4 g/t Ag (incl. high‑grade zone 2.0 m @ 8.5 % Zn, 2.1 % Pb, 21.3 g/t Ag from 31.0 m).

• Hole IB25‑038 – Demonstrated continuity to 120 m depth: 4.2 m @ 3.3 % Zn, 0.3 % Pb, 2.6 g/t Ag; second shallower horizon 3.2 m @ 3.2 % Zn, 0.4 % Pb, 2.6 g/t Ag from 86.6 m.

• Exploration Potential

• Untested geochemical and EM anomalies extend ≥750 m north of B‑9.

• Only ~10 % of the 7.5 km main trend has been drill tested; significant upside remains for lateral extensions and depth continuity.

• Project Context

• Tenure: 200 km² covering a 30 km strike length in central BC, with excellent access to road, rail, power, port and smelter infrastructure.

• Mineralization type: Near‑surface Sedex (zinc‑lead‑silver‑barite) analogous to world‑class Selwyn basin deposits; potential for by‑product silver and critical minerals such as gallium.

• Qualified Person

• Patrick McLaughlin, P.Geo., independent QP under NI 43‑101, has approved the technical content.
