BUNKER HILL PROVIDES PROJECT RESTART UPDATE
FEBRUARY 2024
Early 2024 milestones
• Arrival of mill and other key components from the shuttered Golden Sunlight mine brings the
procurement of Processing Plant equipment past the 80% threshold.
• Power cables and infrastructure have now been ‘dropped’ underground, bringing all parts of the
mine - surface and subsurface - onto low-cost, hydroelectric-dominated mainline electric grid
power.
• Drilling contract for resource definition and expansion to commence in Q2 2024 has been
awarded to Dynamic Drilling, Inc. of Osburn, ID.
Remaining Q1 2024 events
• Demolition of the old mining offices to create space for a new, purpose-built Filtration Plant is
underway and due to complete by the end of Q1 2024.
• LFI of Hutchinson, KS is due to deploy in early March to commence drilling of auger-cast piles as
part of the pre-foundation work for the Process Plant and Filtration Plant buildings.

Toronto, Ontario (February 29, 2024) - Bunker Hill Mining Corp. (TSX-V: BNKR) (OTCQB: BHLL) (“Bunker Hill” or the
“Company”) is pleased to announce that project restart activities have accelerated in early 2024 with early stage
construction activities about to commence in support of new purpose built Process and Filtration Plant buildings.
“With underground infrastructure preparations already well advanced this is a particularly exciting time at our main
site in Kellogg as we transition out of engineering and design and into preliminary construction activities,” said Sam
Ash, Bunker Hill’s CEO, adding that “all is progressing very nicely in what will be a tremendously exciting year for
Bunker Hill.”
PROCESS PLANT EQUIPMENT PROCUREMENT PASSES 80%
Early in 2024 Bunker Hill contracted Barnhart Crane & Rigging, who had previously helped the company successfully
and safely dismantle and transport the Pend Oreille mill from Metaline Falls, WA to Kellogg, ID, to perform a similar
role with critical components purchased from the Golden Sunlight mine. Most conspicuous among these components
was a Rod Mill that will be repurposed as the primary Ball Mill in the new Process Plant to potentially enable the
1800tpd operational milling throughput with significant upside capacity (cf. Bunker Hill 2.0). With these parts now on
site, as well as the full suite of Pend Oreille Mill equipment, procurement of equipment for the new Process Plant
was at 81% as at 22 Feb 24.

TAKING POWER UNDERGROUND
After the connection of the Wardner base of mining operations to the overland power grid in late 2024, on 21
Feb the Bunker Hill mining team safely dropped power underground as part of the first stage of connecting the
highest levels of the mine (those that will be mined in the first three years after restart) to mainline electrical
power. In the coming weeks this power will be used to start the main 7ft ventilaton fan that has already been
procured and is ready to go, and to power the first fully automated mine doors ever to be installed in the Bunker
Hill mine. Iterative power drops will continue throughout the year to ensure all parts of the mine between Levels
5 and 9 that are integral to the mine plan will be ready to support the full suite of mining activities on restart.

In addition to these activities a drilling contact with Dynamic Drilling, Inc. was recently executed in support of a
drill program that will commence in April 2024 and last for much of the year in support of both resource
definition and resource expansion (cf. Press Release of 19 Jan 24 ‘Value Creation Through Exploration’).
DRILLING OF DEEP PIERS
On 4 Mar 24 LFI from Kansas will deploy rigs onto the main Kellogg site to commence the drilling of auger-cast
piles. This is a pre-foundation, preparation of the land activity with drilling due to commence on the west side of
the yard before advancing to the east side. In preparation for this work the building previously used by team
members as an office building, a pre-war building dating from the early 20th century, is in the process of being
demolished (with a period of abatement preceding actual demolition).

Whilst not formally classified as construction activities, this drill program will nevertheless mark the start of a
transition out of an extensive engineering and design phase and into physical activity on the ground. The pre-
foundational design work for this has been a collaborative effort by Barr Engineering Company (the group that
has been designing the Process Plant) and LFI, a company that specializes in auger-cast piles.

regarding its objectives, goals or future plans and statements, including, without limitation: operational activities
related to the planned restart of the Bunker Hill mine and the expected benefits, completion time and budget
thereof; planned exploration of drilling targets; revenue potential opportunities from mining and sale of ore; and
the Company seeking other value-creating opportunities. Factors that could cause actual results to differ materially
from such forward-looking statements include, but are not limited to: the Company’s inability to raise sufficient
capital for its operations; further testing and drilling not yielding additional mineral resources; the fluctuating price
of commodities, capital market conditions, restriction on labour and international travel and supply chains; failure
to identify mineral resources; failure to convert estimated mineral resources to mineral reserves at the expected
rates or at all; the inability to complete a feasibility study which recommends a production decision; 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, t here 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 a s 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; capital, operating and reclamation costs varying
significantly from estimates and the other risks involved in the mineral exploration and development industry; and
those other risks set out in the Company’s public documents filed on SEDAR+. Although the Company believes that

release, and no assurance can be given that such events will occur in the disclosed time frames or at all. The
Company disclaims any intention or obligation to update or revise any forward-looking statements, 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.
Cautionary Note to United States Investors Concerning Estimates of Measured, Indicated and Inferred
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 t hat 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.
