Bunker Hill on Track for June 2026 US Mine Restart Launches Exploration

Program and Provides Project Update

KELLOGG, Idaho and VANCOUVER, British Columbia, March 16, 2026 -- Bunker Hill Mining Corp. (“Bunker Hill ” or the

“Company”) (TSX-V: BNKR | OTCQB: BHLL), is pleased to provide an update on our progress toward the H1 2026 restart of

the Bunker Hill Zinc-Silver-Lead Mine located in the prolific Silver Valley, Idaho, USA.

HIGHLIGHTS

• Safety First: the project has achieved 40 months with no lost time injuries

• Project Progress: construction and commissioning is now 85% complete, and on track for the restart of operations

and first concentrate production in June 2026

• Processing Plant: the mills are turning, with commissioning advancing ahead of plan, complemented by the hiring of

new team members

• Filter Plant: 100% of all mechanical installation completed, with contractors advancing the installation of piping and

electrical ahead of schedule

• Underground Preparation: stockpiles are now sufficient to support the first three months of operations, with

development advancing rapidly to encompass all stopes included in the first six months of the mine plan. Plans

continue to be optimized, focused on maximizing early cash flow, enhanced by the arrival of the new underground fleet

from Caterpillar Inc.

• Exploration Restart : Timberline Drilling has been contracted to conduct 25,000 feet of drilling on higher-grade silver

targets at Bunker Hill and Ranger Page from April 2026. This is the first phase of a multi-phase drilling campaign to run

through 2026

“As the first signs of spring are seen in the Silver Valley, the Bunker Hill project advances at pace towards its June operational

restart. Our team is expanding in size daily, with each new member slotting seamlessly into positions in accordance with our

operational readiness schedule,” says Sam Ash, President and CEO.

“Even more exciting is the contracting of Timberline Drilling, who will support our exploration team by drilling several high-grade

silver targets within both the Bunker Hill and Ranger Page properties beginning in April. This is the initial phase of a multi-

phase campaign that will continue through 2026 and represents the start of the largest drilling campaign conducted at Bunker

Hill since the mine closed in 1981.”

Neither the TSXV nor its Regulation Services Provider (as that term is defined in the policies of the TSXV) accepts

responsibility for the adequacy or accuracy of this news release.

Certain statements in this news release are forward-looking and involve a number of risks and uncertainties. Such forward-

looking statements are within the meaning of that term in Section 27A of the U.S. Securities Act of 1933, as amended, and

Section 21E of the U.S. Securities Exchange Act of 1934, as amended, as well as within the meaning of the phrase ‘forward-

looking information’ in the Canadian Securities Administrators’ National Instrument 51-102 – Continuous Disclosure

Obligations (collectively, “ forward-looking statements”). Forward-looking statements are not comprised of historical facts.

Forward-looking statements include estimates and statements that describe the Company’s future plans, objectives or goals,

including words to the effect that the Company or management expects a stated condition or result to occur. Forward-looking

statements may be identified by such terms as “believes”, “anticipates”, “expects”, “estimates”, “may”, “could”, “would”, “will”,

“plan” or variations of such words and phrases.

Forward-looking statements in this news release include, but are not limited to, statements regarding the Company’s

objectives, goals, priorities or future plans, including the timing of the restart and development of the Bunker Hill Mine; the

achievement of future short-term, medium-term and long-term operational strategies; degree and extent of progress towards

realizing the Company’s objectives, goals, priorities or future plans; the Company’s ability to recruit employees; whether

indicated grade and other qualities of certain minerals remain open at depth and along strike; timing of operations at the

Bunker Hill Mine; potential for future production at the Bunker Hill Mine; any enhancements to upside optionality for future

resource expansion and mill feed sources; the nature and anticipated benefits of the Company’s collaboration with VRIFY;

anticipated recovery rates; the nature and anticipated benefits of the Company's programs; the availability and adequacy of

the Company's existing financing; and benefits to the local community including job creation and stimulation of procurement

from regional suppliers.

Factors that could cause actual results to differ materially from such forward-looking statements include, but are not limited

to, those risks and uncertainties identified in public filings made by Bunker Hill with the SEC and with applicable Canadian

securities regulatory authorities, and the following: the Company’s ability to raise additional capital for project activities on

acceptable terms or at all; Bunker Hill’s ability to operate as a going concern and its history of losses; the fluctuating price of

commodities; capital market conditions; restrictions on labor and its effects on international travel and supply chains; failure

to identify mineral resources; failure to convert estimated mineral resources to reserves; the preliminary nature of metallurgical

test results; the Company’s ability to restart and develop the Bunker Hill Mine and the risks of not basing a production

decision on a feasibility study of mineral reserves demonstrating economic and technical viability, resulting in increased

uncertainty due to multiple technical and economic risks of failure which are associated with this production decision

including, among others, areas that are analyzed in more detail in a feasibility study, such as applying economic analysis to

resources and reserves, more detailed metallurgy and a number of specialized studies in areas such as mining and recovery

methods, market analysis, and environmental and community impacts and, as a result, there may be an increased uncertainty

of achieving any particular level of recovery of minerals or the cost of such recovery, including increased risks associated with

developing a commercially mineable deposit, with no guarantee that production will begin as anticipated or at all or that

anticipated production costs will be achieved; failure to commence production would have a material adverse impact on the

Company's ability to generate revenue and cash flow to fund operations; failure to achieve the anticipated production costs

would have a material adverse impact on the Company's cash flow and future profitability; delays in obtaining or failures to

obtain required governmental, environmental or other project approvals; political risks; changes in equity markets;

uncertainties relating to the availability and costs of financing needed in the future; the inability of the Company to budget and

manage its liquidity in light of the failure to obtain additional financing, including the ability of the Company to complete the

payments pursuant to the terms of the agreement to acquire the Bunker Hill Mine complex; inflation; changes in exchange

rates; fluctuations in commodity prices; delays in the development of projects; and capital, operating and reclamation costs

varying significantly from estimates and the other risks involved in the mineral exploration and development industry. Although

the Company believes that the assumptions and factors used in preparing the forward-looking statements in this news release

are reasonable, undue reliance should not be placed on such statements or information, which only applies as of the date of

this news release, and no assurance can be given that such events will occur in the disclosed time frames or at all, including

as to whether or when the Company will achieve its project finance initiatives, or as to the actual size or terms of those

financing initiatives. The Company disclaims any intention or obligation to update or revise any forward-looking information,

whether as a result of new information, future events or otherwise, other than as required by law. No stock exchange,

securities commission or other regulatory authority has approved or disapproved the information contained herein.

risk factors that could affect the Company’s operations or financial results are included in the Company’s annual information
