Bunker Hill Geophysics Survey Identifies Large-Scale, Near- Surface Anomalies to the South of Existing MINE Footprint
BUNKER HILL GEOPHYSICS SURVEY IDENTIFIES LARGE-SCALE, NEAR-
SURFACE ANOMALIES TO THE SOUTH OF EXISTING MINE FOOTPRINT
HIGHLIGHTS:
• First ever high-resolution model of Induced Polarization (“IP”) geophysical data completed, revealing multiple
large-scale, near-surface anomalies matching known responses of historically mined sulfide mineralization
• Rockford Target displays similar lithologic setting to the historical March stope, the single largest producing
region of the Bunker Hill Mine, and is located 250’ south of the existing mine footprint
• Government Gulch (“GG”) Target includes several zones, with the largest having a similar scale and
orientation to the Quill-Newgard zone, the largest ever continuously mineralized zone identified at the mine
• Shallow nature of target areas (<400 ft depth) allows for low-cost surface drilling from existing roadways
• Significant potential to increase mineralized resource above the water table through further exploration
TORONTO, January 13, 2022 – Bunker Hill Mining Corporation (the “Company”) (CSE: BNKR; OTCQB: BHLL) is
pleased to announce the final results of its ground geophysical program.
Sam Ash, CEO, stated “We are excited to announce the final results of our ground geophysical survey, which
indicates that Bunker Hill’s mineral endowment may extend well beyond the historic mine footprint and into the
expansive 5,800 acre land package. Our analysis has identified multiple large scale, near-surface zones of potential
new mineralization similar to what was historically mined, giving us confidence of possible success in future
exploration campaigns”.
The geophysical program, which ended in September of 2021, has now been run through multiple inversion
modeling processes to create a high -resolution 3D block model. Previously identified lithologic and structural
features are well represented in the data and have allowed for Bunker Hill geologists to further refine geologic
models over the program area previously generated from historic mapping programs.
Two key targets have been identified for further exploration: the Rockford Target and Government Gulch Target.

Figure 2: Geologic Map of IP Anomalies
Mineralization at the Bunker Hill Mine is generally associated with 2 main structural orientations : a WNW strike
for Zn-Pb-Ag massive to disseminated mineralization, (known locally as the “Bluebird” style mineralization) and a
NE trend for Pb-Ag Quartz-Galena vein mineralization. 3D data collection and processing allowed for the survey
to investigate both orientations in the same program. The two key anomalies identified are both tabular in nature
and have WNW strikes. This orientation, along with their size and close association to known large -scale fault
structures, make them similar to the mineralization identified in Bunker Hill’s current Mineral Resource Estimate,
effective November 29, 2021.
The Rockford Target
The Rockford target is hosted at the intersection of the Rockford and Midland faults. Host lithology is the Revett
quartzite, here identified by its relatively low IP and high resistivity values. Disseminated pyrite, a dominant
feature of the Zn-Pb-Ag mineralization shows an elevated IP response, with a decrease in resistivity. Normal
fault wedge-hosted mineralization is known to have existed in multiple locations throughout historic
development at Bunker, specifically the March stope which was the single largest producing region of the
Bunker Hill mine recording ~4.7Mt of material at 12.03% Pb, 5.22 OPT Ag, and 2.25% Zn. Top of the target zone
lies only 150’ from surface, 250’ from the historical mine footprint and is located adjacent to an existing
roadway with excellent access for future drill testing.

A historic down-hole IP geophysical survey on the 21-level of Bunker Hill shows the IP/resistivity characteristics
of both massive and finely disseminated sulfide mineralization within Revett rocks to match those of the
Rockford target zone.
The Government Gulch (“GG”) Target
The Government Gulch fault brings the deeper Belt series rocks into contact with the Revett quartzites. The GG
target zones lie approximately 900’ in the hanging wall of the Government Gulch fault structure and both strike
NW with an approximately vertical, slightly NE dip. The tabular nature of the targets shows well defined, along-
strike truncation of the combined high IP response with very low resistivity values, separating the target zone
from other similar response characteristics of the Prichard thought to identify stratigraphically constrained beds
with elevated pyrite content. The larger of the zones measures approximately 1000’ along strike, 250’ wide and
700’ down dip, placing it on the same scale as the largest-ever identified, continuously mineralized zone at
Bunker Hill, the Quill-Newgard.

fence plane to show correlation and shown in blue blocks.
The top of the GG target zone lies less than 400’ surface and directly adjacent to the already established road
network used for the mobilization of the geophysical program. Bunker Hill is currently developing options to
mobilize an exploration program to advance and delineate both the Rockford and GG target zones.

Cautionary Note to United States Investors Concerning Estimates of Measured, Indicated and Inferred
Resources
This press 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 press release have been disclosed in accordance with NI 43-101 and the
Canadian Institute of Mining, Metallurgy, and Petroleum 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.
Canadian disclosure standards, including NI 43-101, differ significantly from the requirements of the United
States Securities and Exchange Commission (“SEC”), and resource and reserve information contained in this press
release may not be comparable to similar information disclosed by U.S. companies. In particular, and without
limiting the generality of the foregoing, the term “resource” does not equate to the term “reserves”. Under U.S.
standards, mineralization may not be classified as a “reserve” unless the determination has been made that the
mineralization could be economically and legally produced or extracted at the time the reserve determination is
made. The SEC’s disclosure standards normally do not permit the inclusion of information concerning “measured
mineral resources”, “indicated mineral resources” or “inferred mineral resources” or other descriptions of the
amount of mineralization in mineral deposits that do not constitute “reserves” by U.S. standards in documents
filed with the SEC. Investors are cautioned not to assume that any part or all of mineral deposits in these
categories will ever be converted into reserves. U.S. investors should also understand that “inferred mineral
resources” have 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 “inferred mineral resource” will ever be
upgraded to a higher category. 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. The requirements of NI 43-101 for disclosure of “reserves” are also not the same as
those of the SEC, and reserves disclosed by the Company in accordance with NI 43-101 may not qualify as
“reserves” under SEC standards. Accordingly, information concerning mineral deposits contained in our website
may not be comparable with information made public by companies that report in accordance with U.S.
standards.
