Value Creation through Exploration - key lines of activity in 2024:

• Concurrent with engineering, construction and other restart activities, the following will be conducted during 2024:

(1) Planned Resource Conversion: 1250m of Infill holes from UG to improve confidence level of grade and thickness of mineralization.
(2) Near Mine Exploration: 1250 m of drilling, leveraging historic mineralization trends to step out and find additional resources close to existing UG infrastructure.
(3) New Target Exploration: Utilizing modern geophysics to refine and add to new, near-surface exploration targets generated in 2022 within the 5,800-acre Land Package.

Key 2024 Exploration Milestone:

• Bunker Hill intends to issue updated resource during Q4 2024

TORONTO, Jan. 19, 2024 -- Bunker Hill Mining Corp. (the "Company") (TSXV: BNKR) (OTCQB: BHLL) is pleased to provide an update on its planned resource conversion and exploration activities for 2024.

Sam Ash, CEO, said: "In addition to restarting the Bunker Hill mine in 2024, the Company's geologists, led by our new Chief Geologist - Mark Crouter, intend to expand our resources as well as highlight some of the significant geological upside potential contained within our 5,800 acre claim package. We look forward to discussing this on the 6ix video call on Monday, or in person at the Bunker Hill Booth at the AME Roundup Conference in The Vancouver Conference Centre next week."

PROJECT UPDATE

Engineering of the main Process Plant is advancing on track with deep pier establishment scheduled to commence in the next month as part of geotechnical stabilization and preparation of the land for the construction of the Process Plant and Tailings Filtration Plant within the Bunker Hill Yard.

Preparations are ongoing to move all administrative and other staff out of the existing office buildings before they are demolished next month. This will create extra space in the yard for the Tailings Filtration Plant and associated material handling. Administrative and Technical Staff will be moving into new facilities, adjacent but outside to the processing Yard, thereby reducing foot and vehicle traffic within the processing yard.

Up the hill from the Bunker Yard, and adjacent to the expanded Russell Tunnel, the Wardner Mining Operating Yard has recently received an office building which was transferred from Teck's Pend Oreille closed mine site. This mining operating base is also benefiting from additional investment into surface maintenance facilities and supporting infrastructure, sufficient to support ongoing and planned refurbishment of the underground infrastructure. This includes the installation of refurbished ventilation systems, before starting planned UG Resource Conversion, Expansion and Exploration drilling.

All main civil, structural and mechanical outputs are on track to be at IFC before year end. Our long-lead item procurement has resulted in purchase orders having already been issued for the Pre-Engineered Metal Building (PEMB), Ore Silo, Conveyors, Ball Mill Starter Motor, Thickeners Tanks and Inching Drive. Refurbishment of the Pend Oreille mill equipment - the source of most mill components - is advancing on track, concurrent with the move to site of the Mill bought from the Golden Sunlight Mine in Montana by the end of January.

This work will be led by Mark Crouter, the new Bunker Hill Chief Geologist, and will be conducted over the following timetable, to deliver the exploration products listed below:

Fig 4 - Execution Timeline

RESOURCE CONVERSION

Following the establishment of upgraded UG ventilation systems, and starting in April 2024, a 2500m UG drilling program is planned to commence which intends to convert 6.9M tons of inferred mineralization into M&I resources. A conversion rate of >75% is anticipated, which has the potential to add >5 years to the current life of mine.

Figure 5 opposite shows the areas planned to be targeted for resource conversion between UG levels 5-8 (all above the water table, and accessed by existing UG infrastructure).

The results of this drilling is expected to inform an updated resource statement which the Company plans to issue in Q4-2024.

NEAR MINE EXPLORATION

The opportunity to apply modern exploration techniques in conjunction with over 100 years of detailed geologic records presents a unique opportunity to identify and test high quality exploration targets in close proximity to existing mine workings. In addition to resource conversion drilling, a program of near mine exploration drilling is being planned for 2024. The focus of this drilling will initially focus on adding additional resources in the upper levels of the mine where the infrastructure is in place to support drilling. Our goal in 2024 is to add additional resources to our mineral inventory. Target Areas shown in Orange Lozenges in Figure 6, opposite.

NEW TARGET EXPLORATION

The existing mine footprint at Bunker Hill covers approximately 1/3 of the full claim package. Based on the exciting results of a modern 3D geophysics survey conducted in 2021, we are generating high potential drill targets. The potential associated with these targets - all near surface and close to existing infrastructure - could result in the discovery of a completely new area of mineralization at Bunker Hill.

Cautionary Note to United States Investors Concerning Estimates of Measured, Indicated and Inferred Mineral Resources

This news release has been prepared in accordance with the requirements of the securities laws in effect in Canada, which differ from the requirements of U.S. securities laws. Unless otherwise indicated, all resource and reserve estimates included in this news release have been disclosed in accordance with NI 43-101 and the Canadian Institute of Mining, Metallurgy, and Petroleum ("CIM") Definition Standards on Mineral Resources and Mineral Reserves. NI 43-101 is a rule developed by the Canadian Securities Administrators which establishes standards for all public disclosure an issuer makes of scientific and technical information concerning mineral projects. The terms "mineral reserve," "proven mineral reserve" and "probable mineral reserve" are Canadian mining terms as defined in accordance with NI 43-101 and the CIM standards. Pursuant to subpart 1300 of Regulation S-K ("S-K 1300"), the U.S. Securities and Exchange Commission (the "SEC") now recognizes estimates of "measured mineral resources," "indicated mineral resources" and "inferred mineral resources." In addition, the SEC has amended its definitions of "proven mineral reserves" and "probable mineral reserves" to be substantially similar to the corresponding standards of the CIM. Investors are cautioned that while terms are substantially similar to CIM standards, there are differences in the definitions and standards under S-K 1300 and the CIM standards. Accordingly, there is no assurance any mineral reserves or mineral resources that the Company may report as "proven reserves," "probable reserves," "measured mineral resources," "indicated mineral resources" and "inferred mineral resources" under NI 43-101 will be the same as the reserve or resource estimates prepared under the standards adopted under S-K 1300. Investors are also cautioned that while the SEC now recognizes "measured mineral resources," "indicated mineral resources" and "inferred mineral resources," investors should not assume that any part or all of mineral deposits in these categories will ever be converted into reserves. Mineralization described using these terms has a great amount of uncertainty as to their existence, and great uncertainty as to their economic and legal feasibility. It cannot be assumed that all or any part of an "measured mineral resource," "indicated mineral resource" or "inferred mineral resource" will ever be upgraded to a higher category. Under Canadian rules, estimates of inferred mineral resources may not form the basis of feasibility or pre-feasibility studies, except in rare cases. Investors are cautioned not to assume that all or any part of an inferred mineral resource exists or is economically or legally mineable. Disclosure of "contained ounces" in a resource is permitted disclosure under Canadian regulations; however, the SEC normally only permits issuers to report mineralization that does not constitute "reserves" by SEC standards as in place tonnage and grade without reference to unit measures. Accordingly, information concerning mineral deposits contained in this news release may not be comparable with information made public by companies that report in accordance with U.S. standards.
