Bunker Hill Exploration From Discovery to Delivery
Bunker Hill Exploration From Discovery to Delivery
TORONTO, June 04, 2024 -- Bunker Hill Mining Corp. (“ Bunker Hill ” or the “Company”) (TSXV: BNKR, OTCQB: BHLL) is
pleased to provide an update on its recently commenced underground exploration program at the Bunker Hill Mine located in
Kellogg, Idaho. The Company’s 1300-acre land package consists of patented claims and represents the largest single claim
package within Northern Idaho’s prolific Silver Valley. This exploration is being conducted concurrent with the ongoing
construction of the mine’s surface and underground operating facilities.
VALUE RECOGNITION
The Bunker Hill Mine is comprised of multiple structural and strata-bound/form zinc-lead-silver mineralized bodies, many of
which remain open for expansion upward, down dip, and along strike.

The Bunker Hill Underground Mine operated continuously for over 100 years and produced over 5Mt of base metals and
165Moz of silver before operations ceased in 1981 due to environmental performance issues associated with its lead smelter
and zinc plant. The smelting and processing facilities were then dismantled, and the mine allowed to flood up to the 10 Level
with the area being fully remediated as a part of the national Superfund environmental remediation program.
Since then, there has been little modern exploration, and none that is based upon the latest mineral system modeling and in-
mine/near-mine geophysical technologies. The Company therefore considers that with the focused employment of these
modern systems the potential for the discovery of extensions to known mineralization in addition to new blind mineralization to
be good to excellent.
Data mining of the extensive 3,159 historic drillhole database and geologic mapping, coupled with structural and 3D modelling
by the new management team, has identified numerous low-risk, high-reward zinc-lead-silver targets at all levels of the
currently defined deposit.
The Company’s initial ‘proof of concept’ exploration focus, funded by the existing mine restart budget, will be those associated
with the Quill and Newgard mineralized zones, above the existing water level and accessible to planned or existing
underground infrastructure; as shown in Figure 2.

VALUE ADD
This initial program supports the Company’s “Value Add” exploration strategy. This seeks to:
• Discover new high-impact/high-reward mineralization adjacent to historic and/or new underground mine
infrastructure that can be cost/time-efficiently incorporated into the short to medium-term mine plan; and mineable
within a <1-to-2-year time frame.
• Potentially increase mineable tonnes per vertical meter , thereby positively impacting tonnes delivered to the Plant
as well as enabling deferral of certain underground development costs going forward. Or in other words, increase the
total quality of economic tonnes per developed level.
• Validate (and refine) the exploration model to better inform ongoing and future material value creation discoveries
in the more silver-rich portions of the deposit. These are likely to be below the current water level and within the mid to
lower levels of the currently known deposit.
• Refine the Company’s understanding of known REE mineralization at Bunker Hill , specifically Germanium,
Gallium, and Indium.
2024 PLAN DETAIL
The current 9,000 feet (2,700 m) diamond drillhole program, conducted from underground stations and powered by the local
grid is focused on the uppermost levels of the currently defined Quill / Newgard zone. Resource expansion targets have been
identified immediately adjacent to the mine infrastructure and are designed to support and extend the initial 5-years of planned
production at start-up (see Figure 3). Three targets will be tested in this initial 2024 program.
In addition to the Zinc-Lead-Silver mineralization, testing will also be conducted for rare earth elements at the Bunker Hill Mine.
A limited testing program to date has indicated the potential for Germanium, Gallium and Indium; each associated with
sphalerite, zinc mineralization.

The Company will provide periodic updates on this 2024 Resource Expansion program as key targets are tested and/or
geochemical assay batches are received.
CONSTRUCTION UPDATE
The construction advances on plan and budget, targeting the start of mining and mill commissioning in Q4 2024, ramping up to
full 1800 tpd production through Q1 2025.
