Bunker Hill Mining Corp. (TSX: BNKR | OTCQB: BHLL) has announced further successful results from its ongoing exploration drill program testing the high-grade silver-lead Cate-8 Vein discovery adjacent to current development in the upper area of the Bunker Hill Mine in Kellogg, Idaho, and Vancouver, British Columbia.
Drilling Program Highlights
Seven holes have been drilled to date for a total of 2,750 feet from the 8 Level. Assay results for the first five drillholes show significant intercepts, with results for BHE26-01 and BHE26-02 previously reported on May 4, 2026, and May 12, 2026. The last two drill holes, BHE26-06 and BHE26-07, both intersected siderite-galena veins ranging from 1 to 6 feet in length; these holes have been logged, and samples have been submitted to the assay lab.
Exploration Target Model Estimate
The exploration target model estimate for the Cate-8 Vein indicates a range of 50,174 to 167,821 tons at a grade of 9.32 to 5.75 oz/ton AgEq, with potential to expand through additional drilling.
Key Drill Intercepts
- Drill Hole BHE26-02: 28.6 ft length at 5.06 oz AgEq per ton (173.6 AgEq g/t), located 280 ft from current mine development.
- Drill Hole BHE26-03: 15.5 ft length at 11.34 oz AgEq per ton (388.79 AgEq g/t), located 310 ft from current mine development.
This new high-grade silver discovery supports the objective of restoring the mine's metal mix to its historic 50% silver and 50% base metals earlier than expected.
CEO Commentary
Sam Ash, President and CEO, commented: "As we prepare to restart operations this month, these results from the Cate 8 exploration program already exceed our expectations. In particular, the consistency, grade, and thickness of mineralization indicate a new discovery, which will assist with our goal of returning the mine to its historic 50% silver and 50% base-metal mix. Based on this, we are planning to expand the program to potentially define a resource that can be incorporated early in the mine plan. Because of its proximity to existing development and potentially significant tonnage and silver grades in preliminary target estimates, I anticipate that, with continued drill success, we will add the Cate I area to the mine plan in ways that could improve the 2027 and 2028 silver production profile."
Upcoming Webinar
The Company will also host a live investor webinar on Wednesday, June 3, 2026, at 10 am PT to discuss the exploration results and the upcoming June restart of operations at the Bunker Hill Mine. Investors, shareholders, analysts, and other interested parties are encouraged to attend.

Drill Intercepts Table
Table 1: Drill intercepts from maiden drill program on Cate-8 Vein Target
Note: Intercepts listed are drilled length; true thickness is unknown from current data: estimated at 50% of drilled length for BHE26-02 and 03, 60% for BHE26-04, 95% for BHE26-02 and 80% for BHE26-05. Strongly mineralized vein intervals were put on rush assay; lower-grade visually mineralized intervals surrounding these intercepts are awaiting results. Core recovery was good (>95%) in mineralized zones other than BHE26-03 (~25%) and BHE26-04 (50.7%), which were drilled at a very low angle to the Cate-8 structure; these intervals will be drilled from a more ideal location for inclusion of those zones in a potential future resource estimate.
