• Social and environmental activism can negatively impact exploration, development, construction, and mining activities, leading to disruptions and reputational damage.
• Construction and start-up of new mines and projects (e.g., Deepening Extension Project) are subject to various factors, and successful completion is not assured, potentially leading to delays or cost overruns.
• Land reclamation and mine closure requirements may be burdensome and costly, potentially exceeding current estimates.
• The mining industry is intensely competitive, making it difficult to acquire properties, recruit personnel, or secure capital.
• Inadequate infrastructure (power, water, transportation) may constrain mining operations and increase costs.
• Operating cash flow may be insufficient for future needs, potentially requiring additional equity or debt financing on unfavorable terms.
• Fluctuations in the market prices and availability of commodities and equipment (e.g., fuel, tires) affect the company's business and operating costs.
• The company is subject to restrictive covenants in its debt agreements that limit its ability to operate its business, including incurring additional debt or paying dividends.
• Significant indebtedness could adversely affect financial condition, limit access to additional financing, and require a substantial portion of cash flows for debt service.
• Inability to generate sufficient cash to service all indebtedness could lead to liquidity problems, asset disposals, or restructuring.
• Counterparties may default on their contractual obligations to the company, including financial institutions, customers, and service providers.
• Failure to maintain satisfactory labor relations can adversely impact operations, especially with unionized employees.
• Insurance coverage may be inadequate to cover potential losses from various risks and hazards.

• There is no assurance of a sufficient liquid trading market for the Common Shares in the future.
• There is currently no market through which the company's securities, other than Common Shares, may be sold.
• Prevailing interest rates will affect the market price or value of any debt securities.
• Debt securities denominated or payable in foreign currencies may entail significant risk.

Future Outlook

The company intends to use the net proceeds from future securities sales for exploration and development of its mineral properties and for working capital requirements. The Phase 2 drill program at the Furnas Project is underway, comprising a minimum of 17,000 meters, with a greater focus on step-out drilling aimed at further extending known mineralization. Additional gold ounce deliveries under the streaming agreement with RGLD Gold AG are expected to commence in 2028.

Management Comments

• Management is committed to conducting business in an ethical and responsible manner, which it believes will reduce the risk of legal disputes.
• The company continues to monitor developments and policies in Brazil and the impact thereof to its operations; however, they cannot be accurately predicted and could have a material adverse effect on the company’s operations or profitability.

Industry Context

The mining industry is intensely competitive, with many larger companies possessing greater resources. The sector faces increasing public concern regarding environmental and community impacts, leading to social and environmental activism. Global economic conditions, including tariff disputes, health crises, and geopolitical conflicts, significantly influence commodity prices, financing costs, and overall demand for metals. Regulatory trends, particularly concerning climate change and tailings dam safety, are becoming more stringent, potentially increasing compliance costs and operational complexities. The continuous investigation and development of alternative technologies and materials could also reduce demand for copper and gold.

Comparison to Industry Standards

• Canadian standards, including NI 43-101 for mineral reserve and resource estimates, differ significantly from the requirements of the SEC, meaning information may not be directly comparable to similar disclosures by U.S. companies.

Corporate Governance

Legal Proceedings

• The company may be subject to regulatory investigations, civil claims, lawsuits, and other proceedings in the ordinary course of its business.
• Inherited liabilities from past acquisitions have led to a number of claims (including tax, labor, social security, and civil action) which are not individually material but are regularly reviewed by management.
• The Public Prosecutors Office of the State of Bahia (PPO) commenced an audit in 2021 relating to the Caraba Operations' compliance with environmental laws and regulations over its entire operating history (over 40 years).
• A determination by the PPO of non-compliance could result in enforcement actions, including fines, capital expenditures for corrective measures, or in extreme cases, orders causing operations to cease or be curtailed.
• The legal system in Brazil has inherent uncertainties, including inconsistencies in laws, limited judicial guidance, gaps in regulatory structure, lack of judicial independence, corruption, and bankruptcy procedure abuses.
• It may be difficult to obtain swift and equitable enforcement of a Brazilian judgment or a judgment by a court of another jurisdiction in Brazil.

Stakeholder Impact

• **Shareholders**: Potential for dilution from future equity financings, exposure to stock price volatility, no current dividend payments, and potential for shareholder activism. The shelf prospectus offers long-term financing flexibility but introduces uncertainty regarding future capital structure.
• **Employees**: The company's success depends on retaining key management and skilled personnel, and maintaining satisfactory labor relations, which are subject to collective bargaining agreements and potential disputes.
• **Customers**: Demand for copper and gold products is influenced by market prices and the emergence of product alternatives, which could affect sales volumes and revenues.
• **Suppliers**: The company's operating costs and production schedules are affected by the market prices and availability of commodities and equipment, such as fuel, tires, and reagents.
• **Creditors**: The company's significant indebtedness and restrictive covenants in debt agreements could limit its financial flexibility and ability to meet obligations, potentially leading to acceleration of debt repayment in case of default.
• **Local Communities**: Mining activities have perceived environmental and social impacts, leading to potential opposition from NGOs and local community groups, which could disrupt operations and damage the company's reputation. Maintaining strong community relationships is crucial.
• **Regulatory Authorities**: The company is subject to extensive laws and regulations in Brazil, requiring ongoing compliance and permitting. Changes in regulations or enforcement actions could impose significant costs or operational restrictions.

Next Steps

• Offer various securities (common shares, debt securities, warrants, units, subscription receipts, share purchase contracts) from time to time after the effective date of the Registration Statement.
• Deliver prospectus supplements for specific offerings as they occur.
• Continue the Phase 2 drill program at the Furnas Project, with a greater focus on step-out drilling.
• Repay the additional non-priced copper prepayment facility over 21 equal monthly installments, which commenced in April 2025.
• Commence additional gold ounce deliveries under the streaming agreement with RGLD Gold AG, expected in 2028.
• Negotiate the renewal of MCSA's collective bargaining agreement for the Tucum Operation, with negotiations having commenced in late February 2025.

Key Dates

Recommendation

The filing is a standard shelf prospectus, indicating the company is preparing for future financing flexibility rather than announcing immediate operational or financial changes. While recent operational achievements like Tucum reaching commercial production and progress at Furnas are positive, the extensive list of inherent risks in mining, significant existing debt, and exposure to Brazilian political and economic volatility warrant a cautious stance. The lack of immediate price-sensitive news and the long-term nature of the capital raising framework suggest a 'hold' for existing investors, awaiting more specific details on future offerings and their impact on the company's financial structure and growth strategy.
