(TSXV: IZN) (\"InZinc\" or the \"Company\") is pleased to report an additional four drill holes from 2025 exploration diamond drilling at its 100% owned Indy Sedex (zinc-lead-silver-barite) project, located 90 km southeast of Prince George in central British Columbia, Canada. Results from these shallow drill holes (four previously reported, total of 11 drilled), exploring the western expansion and southern extension of near surface mineralization at the B-9 Zone, are summarized below. An additional three drill holes are pending results.2025 Results - Highlights of B-9 Western Expansion Drilling (Table 1)Drill Hole IB25-032 (Figure 1)Widest shallow intersection to date averaging 3.3% Zn, 0.7% Pb and 7.4 g/t Ag over 19.1 m from 29.9 m downholeIncludes high grade zone averaging 8.5% Zn, 2.1% Pb and 21.3 g/t Ag over 2.0 m from 31.0 m downholeIntersection is located 30 m up-dip (west) 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 Results from a hole testing the down-dip projection are pending B-9 Zone - Near Surface Trend Extension to 700 m (Figure 2)Four shallow drill holes IB25-030, IB25-031, IB25-032 and IB25-033 encountered mineralization at the principal horizon, expanding the western mineralization and increasing the B-9 trend to greater than 700 m in lengthRemains open for further exploration at depth and along trendTable 1: B-9 West Trend Expansion - 2025 Diamond Drilling IntersectionsDrill Hole(HQ)From(m)To(m)Interval(m)Zinc(%)Lead(%)Silver(g/t)VerticalDepth (m)IB25-03042.0045.003.003.500.523.6633IB25-03125.6630.004.342.430.394.2718IB25-03229.9049.0019.103.310.667.4123includes31.0033.002.008.482.0921.28and*40.0049.009.003.960.677.39IB25-033NCV Vertical depth is measured from the top of the drill intersection - vertically to surface. True widths are estimated from 100% to 75% and may vary with further revisions from additional drilling.
