Phase Two Program Achieves Highest Grade Drill Intersection At Indy Project

VANCOUVER – InZinc Mining Ltd. reported on the Phase 2, 2025 drill program which has achieved our highest grade drill intersection to date and a significant extension of the B-9 Zone to over 1000 m in strike length at the 100% owned Indy zinc-lead-silver-gallium-barite project, well-located 90 km southeast of Prince George in central BC, Canada. The B-9 Zone remains open for further exploration along trend to the north and at depth.
“We are delighted with the success of the 300 m step-out 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 deposits in northwestern Canada. The Indy project is emerging as a tremendous new discovery opportunity in a premium location,” said Wayne Hubert, CEO.
”Separately, relating to other assets in InZinc’s portfolio. We would like to congratulate American West Metals on the success of their recent financing and announcement of work commencing to advance the West Desert project in Utah where InZinc retains a 50% indium production royalty (NSR) interest.”
The Phase 2 diamond drilling program included six drill holes totalling 800 m. In addition to Hole IB25-043 (231 m), an additional two holes (IB25-041 and 042) were completed on the same east-west (local grid) drill section which, in aggregate, comprised 65% (521 m) of the total meterage in Phase 2. A narrow (0.10 m) zone of “radiolarian-style” sphalerite mineralization was observed in Hole IB25-041 (collared 90 m west of Hole IB25-043) in a position located approximately 120 m up-dip of the B-9 mineralized envelope intersected in Hole IB25-043. No mineralization was observed in Hole IB25-042, which was collared 100 m west of Hole IB25-041.
An additional three holes (IB25-040, 044 and 045) were located at the southern B-9 trend. Hole IB25-040 was terminated in broken ground at 57 m downhole. Hole IB25-044 (102 m) was located 60 m north of massive sulphides discovered in Hole IB25-029 and intersected sectors of visually lower-grade, pyritic mineralization over several metres. Hole IB25-045 (120 m) was drilled from the same location as IB25-040 at the southern extent of the B-9 Zone. This hole intersected a significant fault zone which offsets the B-9 Zone (see Figure 1). Further drilling is required to identify fault movement.
Outlook for 2026 – Focus on Further Expanding and Delineating limits of High-Grade Mineralization.
