Teck Facility Draw

On October 26, 2026, Bunker Hill Mining Corp. (the “Company” or “Bunker Hill”) drew an additional US$2.0 million under its uncommitted demand revolving standby prepayment facility established pursuant to the Standby Prepayment Facility Agreement, dated as of June 5, 2025 (the “Facility”), by and among the Company, Silver Valley Metals Corp. (together with its successors and permitted assigns, “SV Borrower”), and Teck Metals Ltd. (the “Lender”). Following the draw on October 26, 2026, the total draw on the Teck Facility outstanding is US$10.0 million. The proceeds from the drawdown will be used to support working capital requirements and ongoing operational activities as the Company advances toward full commercial production.

As previously disclosed in the Company’s Form 8-K as filed on June 11, 2025, the Facility permits revolving draws up to an aggregate maximum principal amount of US$10.0 million and is uncommitted and repayable on demand. The availability period ends on the earliest of (i) June 30, 2028, (ii) the date on which the project reaches 90% of nameplate capacity, and (iii) termination of the facility by the Lender, in each case subject to the terms and conditions therein. Amounts repaid may be reborrowed during the availability period, and each advance must be at least US$500,000. Amounts drawn bear interest at 13.5% per annum from their funding date to June 30, 2027, and a rate equal 15.0% per annum thereafter, subject to automatic increases. Interest is calculated on a 360-day year and capitalized quarterly in arrears. Upon an event of default, default interest accrues at the applicable rate plus 3.0% per annum.

The Company’s obligations under the Facility are secured by a first-ranking security interest over substantially all property and assets of the obligors, subject to permitted liens.

The foregoing description of the material terms of the Facility is qualified in its entirety by reference to the Standby Prepayment Facility Agreement, dated June 5, 2025, which was filed as Exhibit 10.34 to the Company’s Registration Statement on Form S-1 filed with the Securities and Exchange Commission on June 27, 2025 and the description of the Facility contained in the Company’s 8-K as filed on June 11, 2025, which is incorporated herein by reference.
