INZINC PREPARES FOR 2025 DRILL PROGRAM AT INDY PROJECT IN CENTRAL BC

Inzinc Mining Ltd. has approved expenditures for an early summer 2025 diamond drilling program at the Indy sedex (sedimentary exhalative) (zinc-lead-silver-barite) project (100-per-cent interest) located 90 kilometres southeast of Prince George in central British Columbia, Canada. The company is well positioned with working capital, is permitted (five years, up to 60 drill holes) and anticipates commencement of drilling in the first week of June.

The Indy project is host to discoveries of near-surface zinc-lead-silver and barite mineralization, typical of worldwide sedex deposits. Only 129 sedex deposits have been discovered globally; however, they account for more than 50 per cent of the world's zinc reserves and contribute about 25 per cent of global zinc production. These deposits often include significant silver and critical minerals as byproducts (United States Geological Survey, 2016 (1)).

Indy -- a southern analogue of the prolific Selwyn basin

Sedex deposits are only found in distinctive sedimentary rocks (basins) of specific ages in the geologic record. In 2024 the host rocks at Indy were correlated by age, rock type and mineralization to the renowned Selwyn basin of the Yukon and northeastern British Columbia. The Selwyn basin is a 1,100-kilometre-long sedimentary belt hosting the world's second-largest known accumulation of sedex deposits and districts including several world-class deposits (2).

The Indy project, located approximately 500 km south of the nearest known Selwyn basin deposit, is particularly well located with respect to road, rail, power, port and smelter infrastructure.

Focus on discovery and expansion of near-surface mineral resources

• Near-surface mineralization (zinc-lead-silver) at the B-9 zone, including intercepts up to 10.0 per cent (zinc and lead) and 16.2 grams per tonne silver over 9.9 m (3), extends over 450 m and is open for expansion;
• New high-contrast soil anomaly recently discovered 400 m east of the B-9 zone supports the extension of B-9 mineralization (4);
• Additional large and unexplored targets are defined from 1,100 line km of airborne geophysics, over 6,000 soil samples and multiple years of detailed geology along an 11 km corridor known as the Main trend;
• Extensive tenure covers 200 square km and a 30 km length of underexplored strata in central B.C.

Details of the drill program will be provided closer to the start of the program.

The company is also pleased to announce Michael Westcott, director, has been appointed chairman of the audit committee.

About Inzinc Mining Ltd.

Inzinc is an active explorer at its Indy sedex project (100 per cent) in central British Columbia, Canada. The company is exploring near-surface zinc-lead-silver and barite mineralization discovered at Indy in a new, underexplored mineral region correlating to the prolific Selwyn basin of northeastern B.C. and the Yukon. South32 Ltd. (Australian Securities Exchange, London Stock Exchange, Johannesburg Stock Exchange) became a major tenure holder in the Indy belt by staking approximately 200 square km of adjacent claims in late 2021. Through its equity investment in American West Metals (ASX) and a 50-per-cent royalty interest (net smelter return) from any future production of indium mined at American West's West Desert project, Inzinc is also exposed to a portfolio of North American base metals and precious metals projects.
