InZinc Mining Ltd. reported barite results from 2022 diamond drilling in the Keel area at the Indy project (100% interest) located 90 kilometres southeast of Prince George in central British Columbia, Canada. Barite mineralization, recently discovered at Keel in 2023 drilling, is also found at many of the world's largest Sedex (zinc-lead- silver) deposits. The discovery of abundant barite at Indy is an important development, improving the potential for discovery of district-scale Sedex deposits.

Additional barite results are pending and will provide further insight into barite distribution and its link to Sedex mineralization at the 30 km long Project. The Company is also currently renewing its drill permit for a 5-year term. New results include high grade barite (58.1% barite over 0.35 m within 11.6% barite over 4.0 m) in core at the southeastern Keel trend.

In addition, drill core from 500 m to the north returned 5.4% barite over 20.5 m, extending the Keel barite trend to 700 metres in strike length. Keel is located 4 km north of the B-9 Sedex style zinc-lead-silver mineralization and 1 km southeast of the Delta Horizon where rock sampling returned 5% to 25% barite in numerous samples across a 1.5 km trend. High Grade Barite and Multiple Horizons at Keel Diamond drill hole IB22-017 is from the easternmost Keel area.

Multiple zones of barite mineralization (up to 58.1% barite over 0.35 m) occur within a debris flow breccia geological unit. High barite grades and altered host rocks indicate close proximity to (or within) a vent complex. The multiple horizons of barite mineralization indicate episodes of active venting occurring over long periods of time.

Barite Extended to 700 Metre Trend Diamond drill hole IB22-023 is located 500 m north of Keel. Two distinct barite zones are present with the lower zone yielding continuous barite mineralization (5.4% barite over a 20.5 m) intersection and containing an enriched interval of 9.1% barite over 6.9 m. Similar to intersections at Keel, this barite mineralization is located at or below a black shale to debris flow breccia geological contact, which is a distinctive geological horizon common to Sedex zinc deposits. A trend of barite mineralization over 700 m in length (and open to the north) has now been defined.

Barite and Vents ­ A Vector to the District-Scale Discovery of Sedex Deposits Sedex (or sedimentary exhalative) deposits are the world's most prolific sources of zinc and associated metals. They form around ocean floor hydrothermal vents, producing both metal and barite deposits. Barite mineralization is well known at many, if not all, of the major Sedex deposits and districts in Alaska, Yukon and northeastern BC.

In Sedex districts, two vent types are known. The more economically important vents, which exhale both metals and barite, are called "black smokers". In Sedex districts, and in the deep-sea vent analogues presently active off the coast of North America (Escanaba Trough), "black smokers" are found along trends (rifts) up to 75 km in length.

Identification of "black smokers" can focus exploration into areas of high potential for the discovery of Sedex deposits. At Indy, the discovery of abundant barite will enhance exploration targeting for these deposits.
