Bunker Hill Mining Intersects High-Grade Zinc-Lead-Silver Mineralization
Adjacent to Existing Underground Infrastructure
HIGHLIGHTS
• Multiple high-grade polymetallic (Zn, Pb, Ag) zones intersected in the upper part of the mine, including:
◦ 14.7% Zn 5.2% Pb and 2.10 Ag Opt over 13.2 ft from 380-396.4 ft, DH 7099
◦ 8.83% Zn 2.95% Pb and .85 Ag Opt over 13.5 ft from 361.5-375 ft, DH 7093
◦ 4.99% Zn 1.40% Pb and .48 Ag Opt over 8.8 ft from 66.5-75.3 ft, DH 7097
• To date, Bunker Hill has drilled 15 underground drill holes, with the current drill program expected to conclude in
December 2024.
• Mineralization intersected by the definition drilling conforms well to the inferred resource and in areas extending beyond
the limits of the current resource model.
• Bunker Hill intends to issue an updated resource estimate in Q1 2025, incorporating results from the 2024 drill program.
KELLOG, Idaho and VANCOUVER, British Columbia, Dec. 17, 2024 -- Bunker Hill Mining Corp. (“Bunker Hill ” or the
“Company”) (TSX-V: BNKR | OTCQB: BHLL) is pleased to announce a high-grade zinc zone in drill hole 7099 which is part of
the recently completed underground resource conversion drill program at the Bunker Hill Mine located in Kellogg, Idaho.
The aim of this drill program is to inform an ongoing technical and mine planning program in the upper and de-watered part of
the mine, close to existing underground infrastructure, thereby potentially increasing the Life of Mine at restart.
Sam Ash, President and CEO, stated, "Our Geology team continues to be impressed by the drill results, which consistently
meet or exceed our initial projections. The mineralized intercepts align well with historical mining records, allowing us to
confidently model grade distribution and variability."
ZINC IS A CRITICAL MINERAL TO THE USA
Zinc is designated by the United States Geological Survey as a critical mineral to the USA, as defined by the US Energy Act
of 2022, meaning that it is essential to the economic or national security of the United States. The planned restart of Bunker
Hill in H1 2025 and the subsequent planned processing of its zinc concentrate at Teck’s Trail smelter in British Columbia will
assist in ensuring this critical mineral supply to the US during increasing geopolitical competition.
DETAIL
Drill hole 7099 is the down-dip extent of the Quill zone, suggesting that the zinc and silver grades increase lower in the mineral
system. Drill hole 7093 is toward the upper extents of the Quill zone, with drill hole 7099 at depth, which shows the increasing
grade with depth (Figure 3).

The Company has completed 15 drill holes totaling 5,996 feet (1,828 meters) as part of the 2024 drill program, which was
designed to explore a small portion of the Bunker Hill Mine’s 7 million tons inferred mineralization into higher confidence
resource categories and the life of mine plan. Consistent zinc-lead-silver grades and intercepts observed throughout the
program have bolstered confidence in the potential for resource conversion and expansion at Bunker Hill ( Table 1 ). Given that
this modest resource conversion program only targeted approximately 5% of the substantial inferred resource inventory, the
results support the Project’s growth potential and underscore its strategic importance to the Company's future operations.
The following table highlights selected intercepts from the Company’s drill program announced today.1,2,3

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; the Company requiring additional capital expenditures than
anticipated, resulting in delays in the expected restart timeline; 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
