INZINC ANNOUNCES NON-BROKERED PRIVATE PLACEMENT OF FLOW-THROUGH SHARES AND NON-FLOW-THROUGH UNITS

Inzinc Mining Ltd. has arranged a non-brokered private placement of a combination of: (i) common shares of the company, each issued as a flow-through share, at a price of eight cents per FT share; and (ii) non-flow-through (NFT) units at a price of five cents per unit, for aggregate gross proceeds to the company of up to $1.2-million.

Proceeds from the issuance of the FT shares will support a planned 2026 diamond drilling program targeting new sedex (sedimentary exhalative) discoveries -- primarily zinc with associated lead, silver and potentially gallium (both zinc and gallium are considered critical minerals) -- at the company's wholly owned Indy project, located approximately 90 kilometres (km) southeast of Prince George in central British Columbia. Drill permits have been received and drilling is expected to begin in May, 2026.

Drilling in late 2025 discovered the B-9 Apex zone, including a very high-grade intersection containing 20.1 per cent zinc (Zn), 1.7 per cent lead (Pb) and 9.5 grams per tonne (g/t) silver (Ag) over 3.2 metres (m) within a 58 m wide mineralized and altered envelope. The 2025 program achieved a 125-per-cent drill-defined strike extension of the B-9 zone trend to 1,000 m, culminating with the discovery of the Apex zone. Untested, coincident geophysical and geochemical anomalies extend for at least 1,200 m along strike from the Apex zone, defining a highly prospective corridor of up to 2.2 km with strong potential for both extensions and new discoveries.

Each FT share will qualify as a flow-through share, as defined in Subsection 66(15) of the Income Tax Act (Canada). The proceeds of the FT shares will be used to incur eligible expenses related to the Indy project that qualify:

1. As Canadian exploration expenses (as this term is defined in the tax act), which may be renounced by the company pursuant to the tax act;
2. Either as flow-through mining expenditures or, if the company so determines, as flow-through critical mineral mining expenditures (as both terms are defined in the tax act);
3. For FT shares purchased by eligible British Columbia investors, as B.C. flow-through mining expenditures that meet the criteria set forth in Subsection 4.721(1) of the Income Tax Act (British Columbia).

The company plans to incur qualifying expenditures on or before Dec. 31, 2027 (or such other period as may be permissible under applicable tax legislation), and to renounce all the qualifying expenditures in favour of investors of the FT shares with an effective date not later than Dec. 31, 2026.

Each unit will consist of one non-flow-through common share and one-half of one common share purchase warrant. Each whole warrant will entitle the holder to acquire one non-flow-through common share at an exercise price of 10 cents per warrant share until 4:30 p.m. Pacific Time on that date that is 24 months from the closing date of the offering. Closing of the offering is expected to occur on or around April 9, 2026.

Proceeds from the issuance of the units will be used for general working capital.

The offering is subject to regulatory approvals. The securities issued pursuant to the offering will be subject to a four-month-and-one-day hold period under applicable securities laws.

In connection with the offering, certain finders may receive a cash fee and/or non-transferable finders' warrants in connection with securities purchased under the offering by investors that are found by the finders, in accordance with the policies of the TSX Venture Exchange.

Certain directors or officers of the company may subscribe for units under the offering. The participation of the directors and officers in the offering will constitute a related party transaction for the purposes of Multilateral Instrument 61-101, Protection of Minority Security Holders in Special Transactions. The company is exempt from the requirements to obtain a formal valuation and minority shareholder approval in connection with the insider participation in reliance on sections 5.5(a) and 5.7(1)(a) of MI 61-101, as neither the fair market value of the securities to be issued, nor the fair market value of the consideration for the securities to be issued, will exceed 25 per cent of the company's market capitalization as calculated in accordance with MI 61-101.

About Inzinc Mining Ltd.

Inzinc has discovered and is advancing near-surface exploration at the 100-per-cent-owned Indy project in central British Columbia, Canada. The extensive tenure at Indy covers 200 square km and a 30 km length of underexplored, prospective strata in central B.C. The Indy project is well located with respect to road access, rail, power, port and smelter infrastructure. In 2025, the company announced the extension of the B-9 mineralized trend to a drill defined strike length of greater than 1,000 m and integrate the following.

Significant drill results from B-9 Apex zone (replacement mineralization):

• 15.4 per cent Zn, 1.3 per cent Pb and 7.2 g/t Ag over 4.2 m;
• Including 20.1 per cent Zn, 1.7 per cent Pb and 9.5 g/t Ag over 3.2 m.

Significant drill results from the near-surface B-9 discovery zone (primary mineralization):

• 8.0 per cent Zn, 2.0 per cent Pb and 16.2 g/t Ag over 9.9 m;
• 11.0 per cent Zn, 2.3 per cent Pb and 27.1 g/t Ag over 3.0 m;
• 9.3 per cent Zn, 2.4 per cent Pb and 18.0 g/t Ag over 3.1 m;
• 5.5 per cent Zn, 0.5 per cent Pb and 3.4 g/t Ag over 6.7 m;
• 3.3 per cent Zn, 0.7 per cent Pb and 7.4 g/t Ag over 19.1 m.

South32 Ltd. became a major tenure holder in the Indy belt by staking approximately 200 square km of adjacent claims in late 2021.

Additionally, Inzinc will receive 50 per cent of the revenue (NSR (net smelter return)) from the sale of indium mined from American West Metals' West Desert project, Utah. Through its equity investment in American West, Inzinc is also exposed to a portfolio of North American base metals projects.
