Negatives

• The Bunker Hill Mine restart project has been delayed by up to four months, now anticipated to commence in mid-2026.
• The total restart expenditure forecast for the mine has significantly increased from US$67 million to US$103 million, indicating higher capital requirements.
• The company still carries a substantial accumulated deficit of US$96,253,046 as of June 30, 2025.
• There is substantial doubt about the company's ability to continue as a going concern without securing additional financing.
• The company was not in compliance with the working capital covenant for its Series 1 and Series 2 Convertible Debentures as of March 31, 2025, requiring a waiver from debenture holders.
• The company has not yet generated any revenue from operations, remaining in a pre-production development stage.

Risks

• Substantial doubt exists about the company's ability to continue as a going concern due to its accumulated deficit of US$96,253,046 and reliance on future financing.
• The Bunker Hill Mine restart project faces risks of further delays and cost increases beyond the current US$103 million forecast, which could adversely affect funding and financial condition.
• Payment bonds securing US$14,000,000 due to the EPA for cost recovery may not be renewable or may only be renewable on unfavorable terms, potentially leading to a default under the settlement agreement.
• The company has no recent operating history or revenue from operations, indicating continued negative cash flows until successful commercial production is achieved.
• Mineral exploration and production activities are inherently speculative and involve high risks, including economically insufficient mineralized material, fluctuating production costs, labor disputes, unanticipated geologic conditions, environmental hazards, and equipment failures.
• Commodity price volatility (silver, lead, zinc) can significantly impact the economic viability of the mine and the company's ability to secure financing.
• The mine's development and production plans, and cost estimates in the Technical Report Summary, may not be realized as they are not based on a feasibility study demonstrating economic and technical viability.
• Wastewater treatment costs from the Idaho Department of Environmental Quality (IDEQ) are subject to fluctuations and are not entirely within the company's control.
• Estimates of mineral reserves and resources are subject to evaluation uncertainties, which could result in project failure or downward revisions.
• The company is subject to extensive governmental regulations, and the inability to obtain or maintain required permits (e.g., air quality, reclamation and closure plans) could delay or prohibit operations.
• Environmental hazards caused by previous owners of the mine may exist, leading to unpredictable and unexpected liabilities.
• Changes in climate change regulations could result in increased operating costs (e.g., carbon taxes) and negatively impact competitiveness.
• Land reclamation requirements for properties may be burdensome and expensive.
• Social and environmental activism could adversely affect the company's reputation and financial condition or its relationships with local communities.
• The mining industry is highly competitive, potentially limiting the company's ability to acquire additional properties or retain qualified managerial and technical employees.
• Dependence on joint ventures and other partnerships (Sprott, Teck, Monetary Metals) exposes the company to risks if partners fail to meet obligations or disputes arise.
• The company's operations depend on information technology systems, which are subject to risks of network disruptions, security breaches, and cyber-attacks.
• Compliance with corporate governance laws and financial reporting standards (e.g., Sarbanes-Oxley Act) increases legal and financial compliance costs and demands on resources.
• Future sales of substantial amounts of securities, including those registered in this filing, will have a highly dilutive effect on existing ownership.
• The company's common stock is currently deemed a 'penny stock,' which may make it more difficult for investors to sell their shares.
• FINRA sales practice requirements may limit broker-dealers' ability to recommend the company's common stock, potentially affecting marketability.
• The company has never paid dividends and does not expect to in the foreseeable future, meaning investors may not receive cash returns.
• The issuance of additional shares of common stock in the future may negatively impact the trading price of the company's securities.
• The trading market for the company's common stock could be influenced by research and reports from industry or securities analysts, which are beyond the company's control.
• Failure to satisfy the continued listing or trading criteria of the TSX Venture Exchange and OTCQB may result in delisting or removal of trading of the common stock.

Future Outlook

The company anticipates the Bunker Hill Mine restart to commence in mid-2026. It is actively pursuing a possible debt funding package from the Export-Import Bank of the United States (EXIM) and may seek additional future equity financings to support its operations and development plans.

Management Comments

• Management believes the Mine is well positioned for development and an eventual return to production.
• The company believes Crescent's lawsuit is without merit and intends to vigorously defend itself.

Industry Context

Key Dates

Recommendation

While the substantial capital raise and comprehensive debt restructuring significantly improve the company's liquidity and address immediate going concern risks, the project remains in a pre-production development stage with increased capital expenditure forecasts and a delayed restart timeline. The long-term viability is still dependent on successful mine commissioning and commodity prices. The positive financial restructuring is offset by the inherent risks of a development-stage mining company and the increased project costs, suggesting a 'hold' for investors to monitor execution and operational progress.
