Bunker Hill Mining Corp. (TSX-V: BNKR) (OTCQB: BHLL) is pleased to announce total funding of US$10.3 million, including a cash order book for its previously announced brokered private placement that has reached a gross amount of approximately US$6.5 million, and additional debt settlement and equity payments totaling US$3.8 million. In addition, the Company announces certain updates to the overall financing initiative and capital restructuring as described in prior announcements on March 6, 2025 and March 25, 2025. The capital restructure is anchored by an equity investment by Teck Resources Limited, and includes the conversion into equity of certain outstanding debt, and the modification of certain existing royalty and stream financing arrangements with Sprott Streaming and Royalty Corp.

“The total equity funding amount reaching above the minimum US$10 million is a welcome milestone along the path to delivering the major capital restructuring plans announced earlier in the year,” said Sam Ash, Bunker Hill’s President and CEO. “We look forward to working with regulators and shareholders to close this transaction in the coming weeks”.

Projected Highlights on Final Closing:

• 40% reduction in total debt, 58% reduction in gross revenue royalty costs and 22% improvement on debt-to-total capitalization ratio, leading to significant improvement in asset resilience.
• Liquidity raised is expected to be sufficient to advance the total project to 85% completion in Q4 2025, with the processing plant 100% complete and starting its commissioning, UG development 100% complete with ore being stockpiled to support commissioning and ramp up, and the tailings filter press 50% complete with all major equipment installed.
• To bring the operation to sustainable free cash flow in H1 2026, the Company intends, with the support of strategic investors, to raise an additional US$30 million of equity by the end Q4 2025 to enable a robust ramp up to nameplate production of 1,800tpd.

Furthermore, in connection with the Brokered Offering, the Company is pleased to announce a lead order by Sprott Streaming for 10,000,000 Units.

Each Unit issued under the Offerings will consist of one share of common stock  and one-half of one Common Share purchase warrant, with each whole Warrant exercisable for one additional Common Share at a price of C$0.25 per Warrant Share for a period of three years following the date of issuance.

Separately, Sprott Streaming intends to transfer up to 30,000,000 Common Shares to certain investors who subscribe for and purchase Units under the Brokered Offering. Sprott Streaming is independently making such Common Shares available to such investors in support of the Brokered Offering on a private basis and in recognition of current equity market conditions, and will not receive any direct or indirect consideration or compensation for doing so.

The Company intends to use the net proceeds of the Offerings to support the construction, start-up and ramp-up of the Bunker Hill Zinc-Silver-Lead Mine in the Silver Valley, Idaho. The closing of the Offerings remains subject to stock exchange and regulatory approvals and, in the case of the Non-Brokered Offering, a minimum Funding Amount of US$10 million, receipt of the Stockholder Consent (as defined below), closing of the Debt Restructuring Transactions (as defined below), and other customary closing conditions. There can be no assurance as to whether or when either or both of the Offerings may be completed, either on the terms previously announced, described herein or at all.

Standby Facility Developments

The Company and Teck have agreed that the previously announced uncommitted revolving standby prepayment facility of up to US$10 million, to be provided by Teck to the Company at closing of the Non-Brokered Offering, will bear interest at a rate of 13.5% per annum until June 30, 2027 and a rate equal to 15.0% per annum thereafter, calculated and capitalized quarterly. The SP Facility will be available to the Company, until the earlier of (i) June 30, 2028, or (ii) the date on which the Project hits 90% of name plate capacity or on the date on which the Company is cashflow positive for a quarter, unless terminated earlier by Teck. The SP Facility is to be secured by a security interest over all assets, properties and undertaking of the Company and its wholly-owned subsidiary Silver Valley Metals Corp in form and scope similar to the security held by Sprott Streaming, with certain security to be held on a first priority basis. No bonus securities of the Company will be issued to Teck in connection with the SP Facility, nor is the SP Facility convertible into securities of the Company.

Offtake Amendments

As announced in the Company’s news release dated March 6, 2025, the Company has agreed to amend certain offtake agreements previously entered into with respect to the Project. In connection with the Non-Brokered Offering, the parties intend to amend the existing zinc offtake agreement (with an effective date of November 10, 2023) and the lead concentrate offtake agreement (with an effective date of November 20, 2023) between Teck and Silver Valley, pursuant to which, among other amendments, the offtake under each respective agreement will apply to life-of-mine production rather than the current 5-year term.

Short-Term Bridge Financing

As previously disclosed, the Company and Teck agreed to a US$3.4 million unsecured promissory note. The Promissory Note ensures sufficient short-term funding until the Offerings close and bears interest at a rate of 12% per annum, with such interest being capitalized and added to the principal amount outstanding monthly under the Promissory Note. The Promissory Note is available in multiple advances, at the discretion of Teck, and is payable by the Company in cash on demand from Teck. The full principal amount of $3.4 million has been advanced under the Promissory Note to the Company. No bonus securities of the Company will be issued to Teck in connection with the Promissory Note, nor is the Promissory Note convertible into securities of the Company.

Equity Payment to C&E Tree Farm, L.L.C.

Silver Valley and C & E Tree Farm, L.L.C previously entered into an option agreement dated March 3, 2023, pursuant to which Silver Valley has an option to purchase certain real property in Idaho, USA, from C&E upon making a cash payment of US$3,129,500, subject to adjustment for lease payments made pursuant to a commercial lease agreement between the parties. The Company wishes to satisfy a portion of the purchase price payable under the Option Agreement through the issuance of equity securities. Subject to the prior approval of the TSX Venture Exchange, the Company, Silver Valley and C&E intend to enter into an equity payment agreement, pursuant to which the Company will issue 4,761,905 Units at a deemed price of US$0.105 per Unit in satisfaction of US$500,000 of the purchase price payable under the Option Agreement.

Additional Debt Settlement

Further to the Company’s news release dated March 25, 2025, the Company intends to settle outstanding receivables and other amounts owing (including, where applicable, accrued and unpaid interest thereon) in the aggregate amounts of up approximately US$3,072,254 and C$195,000 with certain creditors, insiders and contractors of the Company or Silver Valley through the issuance of equity securities at the Offering Price. The Company intends to enter into debt settlement agreements with such creditors, insiders and contractors, concurrently with the closing of the Offerings, in order to preserve its cash for the potential restart and ongoing development of the Project. The Debt Settlements remain subject to prior approval of the TSX-V.

In connection with the Debt Settlements, the Company proposes to issue up to:

1. 761,904 Units to MineWater LLC as further described herein;
2. 4,642,857 Common Shares to Sprott Streaming, as further described herein;
3. 257,379 Common Shares to four directors of the Company for their services for the period beginning on March 1, 2025 and ending on April 30, 2025. Given that the amounts owed for the Director Services exceed the limits under the TSX-V policies in respect of debt settlements to non-arm’s length parties (being a maximum of C$5,000 per person and, in the aggregate, C$10,000 per issuer), the Company will be seeking shareholder approval for the issuance of Common Shares to these Directors prior to issuance; and

Each Unit issued pursuant to the Debt Settlements will consist of one Common Share and one-half Warrant, with each whole Warrant exercisable for one additional Warrant Share at an exercise price of C$0.25 per Warrant Share for a period of three years following the date of issuance.
