Bunker Hill Mining Provides Exploration Update Defines High-Grade Silver Target

Bunker Hill Mining Corp. (“Bunker Hill” or the “Company”) (TSXV:BNKR|OTCQX:BHLL) is pleased to report that in-mine exploration is continuing to delineate targets designed to support higher run-of-mine grade as we move towards production in H1|25.

The 8,000-foot (~2,440 metres) definition drill campaign was initiated in May this year with the goal of converting inferred mineralization into higher-confidence categories and increasing reserves and mine life. A second drill campaign, totaling approximately 3,000 feet (~910 metres), will commence in Q1|25 to test the selected advanced target by Q2|25.

“Drill assays received to date continue to return results that align with or exceed our original estimates. It is anticipated that the drill program will positively impact the short- to medium-term production profile and economics of Bunker Hill, as presented in the 2022 Pre-Feasibility Study,” noted Sam Ash, President and CEO. “The Company is on track to complete a resource estimate update incorporating these results in the first quarter of 2025”.

“Our exploration strategy focuses on delineating resources from our large Inferred inventory in the short term while preparing for medium and longer-term exploration success by advancing exploration targets to the drill ready stage. Ongoing datamining of the extensive historical database has defined a high-grade, 5 to 10 ounces per tonne, approximately 500,000-to-1-million-ounce silver target that we are excited to test in the first quarter of 2025. If successful, this would represent a significant return on our exploration investment and aligns with our strategic objective of boosting silver production during ramp-up and commercial production while maintaining steady-state silver production of at least 700,000 oz per annum over the life of mine”.

Overview of Exploration Targets

Based on the new drill data received and the available historical geological data, the number of identified exploration targets across the deposit has increased from 12 to 14, with one of the new targets outlined below. Figure 1 below highlights the current resource delineation program. Figure 2 below highlights the proposed drill plan for the high-grade silver target between the 7 and 9 Levels.

2024 Exploration Program

The 2024 drill campaign, which totals 19 drill holes (8,000 feet), will be completed at the end of December. It aims to confirm historical drilling and contribute to an updated NI 43-101-compliant resource and reserves statement expected to be published in Q1|25.

As detailed in Table 1 below, assays have been received for the first six holes, highlights of which include:

The full assay table is attached in Appendix 1.

An additional drill campaign, totaling 3,000 feet (~910 metres), is expected to commence in Q1|25. This program will follow up on vein-type drill intercepts centred around the historic drill hole #3402, completed before the closure of the mine in 1982 (Table 2). Early indications are this program, if successful, may significantly add to our current silver resource. This material could be available for mining in 2025.

NEXT STEPS:

Completion of the 2024 drill campaign, which focuses on the systematic in-fill drilling and resource conversion in the Quill Newgaurd ore body

Updated mineral resource and reserve issued in Q1|25
- Commencement of exploration drilling in the newly identified high-grade silver target with a preliminary 3,000-foot drill campaign in early 2025
- Continue resource expansion and conversion drilling throughout 2025, focusing on resource expansion and conversion of the Quill and Newgard areas between the 6 and 10 levels
