InZinc Announces Non-Brokered Private Placement of Flow-Through Shares and Non-

Flow-Through Units

Vancouver, BC – InZinc Mining Ltd. (TSX -V: IZN) (“InZinc” or “Company”) is pleased to announce a non -

brokered private placement (the “ Offering”) of a combination of: (i) common shares of the Company (“Common

Shares”) each issued as a “flow-through share” (such Common Shares being “FT Shares”) at a price of $0.08 per

FT Share; and (ii) non-flow-through units (“Units”) at a price of $0.05 per Unit, for aggregate gross proceeds to the

Company of up to $1,200,000.

Proceeds from the issuance of the FT Shares will support a planned 2026 diamond drilling program targeting new

Sedex 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 km southeast

of Prince George in central British Columbia (the “Indy Project”). 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% Zn,

1.7% Pb and 9.5 g/t Ag over 3.2 m within a 58 m wide mineralized and altered envelope. The 2025 program

achieved a 125% drill-defined strike extension of the B-9 Zone trend to 1000 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 “Tax Act”). The proceeds of the FT Shares will be used to incur eligible expenses related to the Indy

Project (the “Qualifying Expenditures“) that qualify:

(i) 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;

(ii) 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); and

(iii) for FT Shares purchased by eligible British Columbia investors, as " BC 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 December 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 December 31, 2026.

Each Unit will consist of one non -flow-through Common Share and one-half (½) of one Common Share purchase

warrant (a “Warrant”). Each whole Warrant will entitle the holder to acquire one non-flow-through Common Share

(each, a “Warrant Share”) at an exercise price of $0.10 per Warrant Share until 4:30 pm (Pacific time) on that date

that is 24 months from the closing date of the Offering (the “ Expiry Time”). Closing of the Offering is expected to

occur on or around April 9, 2026 (the “Closing Date”).

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 finder’s warrants in

connection with securities purchased under the Offering by investors that are found by the finder, 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 ("MI 61-101"). 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%

of the Company's market capitalization as calculated in accordance with MI 61-101.

This news release does not constitute an offer to sell or a solicitation of an offer to buy any of the securities in the

United States of America. The securities have not been and will not be registered under the United States Securities

Act of 1933 (the "1933 Act") or any state securities laws and may not be offered or sold within the United States or

to U.S. Persons (as defined in the 1933 Act) unless registered under the 1933 Act and applicable state securities

laws, or an exemption from such registration is available.
