INZINC DISCOVERS NEW ANOMALY SUPPORTING EXTENSION OF NEAR SURFACE MINERALIZATION AT INDY SEDEX PROJECT, CENTRAL BC

A new soil anomaly has been identified to the east of Inzinc Mining Ltd.'s B-9 zone at the Indy sedex (zinc-lead-silver) project (100-per-cent interest) located 90 kilometres southeast of Prince George in central British Columbia, Canada. The new Hilo anomaly is located 400 metres east of the B-9 zone, where 450 m of shallow mineralization including an intercept of 10.0 per cent (zinc and lead) and 16.2 grams per tonne silver over 9.9 m is outlined by previous drilling. The Hilo anomaly is suggestive of the potential eastward continuation of B-9 zone mineralization.

Indy -- a high-potential southern analogue of the prolific Selwyn basin

In 2024, in addition to discovery of extensive barite mineralization, stratigraphy of the Indy project was age constrained and correlated to one of the world's most prolific sedex zinc-lead-silver-barite belts, the Selwyn basin. The Selwyn basin hosts the world's second-largest accumulation of sedex deposits, including some of the world's largest. Previously the mineralized sequences within the 1,100 km long Selwyn basin were only known to occur in the Yukon and northeastern British Columbia. Recent work strongly indicates the Indy project represents a southern analogue of the Selwyn basin strata and its related mineralization (see news release 2024-06, May 16, 2024, for details). The Indy project, located just 90 km from Prince George, is particularly well located with respect to road, rail and power infrastructure.

Renewal of a five-year, 60-drill-hole permit was received in mid-2024. The company is well positioned with working capital of $2.0-million and has commenced planning for 2025 activities.

New Hilo anomaly -- expansion potential of B-9 zone mineralization

The Hilo anomaly is outlined by new (2024) soil geochemical sampling extending over an area of 2.0 km by 350 m east of the B-9 zone mineralization. The B-9 zone has been intersected in 13 of 15 drill holes over a 450 m strike length to a depth of 130 m and remains open for expansion in all directions.

• Hilo anomaly -- 450 m strike with strong zinc, lead and barium in soil;
• Located 400 m east of B-9 zone;
• First barium in soil anomaly proximal to B-9 zone;
• To date, only 450 m of the extensive 2.4 km long soil Anomaly B (zinc, lead, silver, barium) has been drill tested and is host to B-9 zone mineralization;
• Airborne EM geophysical surveys identify a strong conductive response over 1.4 km coinciding with the upper or eastern edge of the soil Anomaly B and with B-9 zone mineralization;
• Hilo anomaly is potentially indicative of an eastward continuation of B-9 zone mineralization.

Additional fall 2024 work at Indy included approximately 2.2 km of road rehabilitation and new trails to gain access to the Keel West and Delta targets in preparation for drilling.

South32 increases exploration activities to the north of Indy

South32 Ltd., a globally diversified metals and mining company, independently staked 200 square kilometres of mineral claims northwest and adjacent to Indy in late 2021. In 2024, South32 substantially increased exploration activities at the Maguire sedex project, including over 600 line km of airborne geophysics and geological and geochemical programs.

Property-wide sedex drill targets

The widespread distribution of mineralization (sulphide and barite) and related geochemical and geophysical anomalies across the 7.5 km Main trend define high-potential exploration targets for sedex deposits at Indy:

• Hilo anomaly -- 450 m strike with strong zinc, lead and barium in soil, located 400 m east of B-9 zone;
• B-9 zone -- near-surface sedex-style mineralization (up to 10.0 per cent zinc and lead, 16.2 g/t silver over 9.9 m) at the B-9 sulphide zone (450 m strike open for expansion in all directions), within a 2.4 km long multielement soil geochemical anomaly (Anomaly B);
• Anomaly C -- untested, very high-contrast multielement soil geochemical anomaly extends over 750 m in length;
• Echo -- a 1.9 km long continuous high-contrast, multielement (zinc, lead, barium signatures) soil geochemical anomaly with approximately 900 m remaining to be drill tested;
• Keel barite -- extensive barite mineralization (700 m strike) at Keel with local enrichment in zinc-lead sulphides at Keel West;
• Delta -- additional widespread barite mineralization at surface (up to 25 per cent barite in rock samples) with zinc-lead enrichment occurring over a 1.3 km trend, untested and located one km northwest of Keel.

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 British Columbia and the Yukon. South32 became a major tenure holder in the Indy belt by staking approximately 200 square kilometres of adjacent claims in late 2021. Through its equity investment in American West Metals (ASX) and a 50-per-cent royalty interest (NSR) 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.
