Drilling Further Expanding Sedex Mineralization At Indy Project

VANCOUVER – InZinc Mining Ltd. reports on the remaining three shallow drill holes (eight previously reported, total of 11 drilled in 1089 m), successfully extending the depth of the B-9 Zone to 120 m below surface at its Indy Sedex (zinc-lead-silver-barite) project. Drilling in 2025 has now increased the B-9 mineralized trend by over 40% to 700 m in length and has expanded near surface, high-grade mineralization at the road accessible discovery located 90 km southeast of Prince George in central British Columbia, Canada.
Highlights of New Results – Drill Hole IB25-038 1) Depth Extension – The principle mineralized horizon was intersected (3.3% Zn, 0.3% Pb, 2.6 g/t Ag over 4.2 m from 121.4 m downhole) 40 m down-dip (depth) of 2018 massive sulphide discovery (IB18-009 previously released, averaging 8.0% Zn, 2.0% Pb, and 16.2 g/t Ag over 9.9 m from 78.1 m downhole), indicating good continuity of mineralization to a depth (down-dip) of 120 m – remains open for expansion down-dip. 2) More than One Horizon Recognized – A second, shallower mineralized horizon intersected (3.2% Zn, 0.4% Pb, 2.6 g/t Ag over 3.2 m from 86.6 m downhole) is also present in adjacent drill holes north and south within a wide mineralized envelope. The mineralized envelope is recognized by its distinctive “radiolarian” type replacement mineralization and remains open at depth and along trend.
Highlights of 2025 Exploration Drilling Results Previously Released – Trend Extension by greater than 40% to over 700 m – Open along strike and down-dip: 1) All 2025 drill holes across the 700 m long B-9 trend, reported mineralization at the principle mineralized horizon with 9 holes returning mineralization above grade/width cut-off. 2) All intersections defining B-9 mineralization, including drilling prior to 2025, are located within 120 m of surface. 3) B-9 trend remains open for further exploration along trend and at depth. 4) Drilling to-date at Indy has tested just 10% of the prospective 7.5 km Main Trend.
Near Surface Massive Sulphide Areas Expanded: 1) Additional shallow, high-grade massive sulphides discovered in northern area (IB25-029: 11.0% Zn, 2.3% Pb and 27.1 g/t Ag over 3.0 m from 61.0 m downhole) located 80 m north of Hole IB18-003 (9.3% Zn, 2.4% Pb and 18.0 g/t Ag over 3.1 m from 25.0 m downhole) – open for expansion to the north. 2) Gallium present in zinc-rich massive sulphide sample.
Zone Widens Directly Below Surface. 3) Widest, intersection to-date (IB25-032, averaging 3.3% Zn, 0.7% Pb and 7.4 g/t Ag over 19.1 m from 29.9 m downhole – including 8.5% Zn, 2.1% Pb and 21.3 g/t Ag over 2.0 m from 31.0 m downhole and containing semi-massive sulphides. 4) Intersection is located 30 m up-dip (west) of 2018 massive sulphide discovery (IB18-009, previously released November 13, 2018) averaging 8.0% Zn, 2.0% Pb, and 16.2 g/t Ag over 9.9 m from 78.1 m downhole.
The extensive tenure at Indy covers 200 square km and a 30 km length of under-explored strata in central British Columbia. The Indy project is well located with respect to road, rail, power, port and smelter infrastructure.
The near surface mineralization (zinc-lead-silver and barite) discovered across the 7.5 km Main Trend at Indy is typical of worldwide Sedex deposits and districts. These deposits often include significant silver and critical minerals as by-products.
