InZinc intercepts zinc and silver in shallow zones at Indy

15.0 m grading 7.0% Zn, 3.2% Pb and 17.5 g/t Ag from 67.1 m downhole including a Silver-Rich Zone of 3.0 m grading 61.8 g/t Ag, 10.7% Zn, 11.7% Pb and 2.8 g/t Gallium. Vancouver, British Columbia--(Newsfile Corp. - July 29, 2026) - InZinc Mining Ltd. (TSXV: IZN) ("InZinc" or the "Company") is very pleased to report the discovery of strongly mineralized, stacked zones in shallow drill intersections from the spring 2026 diamond drill program at the B-9 Apex Zone ("Apex") at the 100% owned Indy Sedex (zinc-lead-silver-gallium-barite) project. Indy Sedex ("Indy") is located 90 km southeast of Prince George in central British Columbia, Canada and benefits from direct road access connecting to highways, rail and ports, nearby power and the domestic smelter at Trail, BC.

These new discoveries, in aggregate with the B-9 Discovery Zone ("B-9 Discovery") extending for 1000 m to the south of Apex, demonstrate the growing potential for open pit accessible, conventional sulphide resources at Indy (Figure 1). Further drilling is required to explore the limits of such a potential resource and the entire 1000 m long B-9 Trend remains open for expansion. The remaining area between the new Apex zones and B-9 Discovery has emerged as a near term high-potential drill target area.

"Additionally, Indy is a recent Sedex-style discovery in BC with 30 km of unexplored strata and roads connecting to the extensive logistics available in centra
