Ero Copper Corp. (ERO): Intro

• Primary operating assets: Vale do Curaçá (historic, large-scale open pit and underground operations) and the MCSA (Mineraçao Caraíba) complex (including Pilar and RDM underground mines).
• Listing: Equity traded in the USA (ticker: ERO).

• Founding and early growth: Ero evolved from a combination of Brazilian operating experience and Canadian capital markets activity; key growth accelerated after the acquisition and consolidation of the Vale do Curaçá assets and the Caraíba operations.
• Expansion through brownfield development: Significant capital programs have focused on expanding mine life and throughput at both Curaçá and MCSA, including shaft and processing upgrades and exploration-driven reserves replacement.
• Public-market timeline: Ero listed on North American exchanges to access development capital and liquidity for its Brazilian portfolio.

• Major shareholders: Institutional investors and resource-focused funds hold significant stakes; management and insiders typically retain material ownership positions aligning incentives with long-term value creation.
• Board and management: Comprised of mining industry professionals with operating, technical and capital markets experience; governance aims to balance operational risk, environmental responsibility and capital allocation.

• Mission: Operate safe, sustainable and cost-efficient copper production to supply a critical metal for electrification and decarbonization.
• Vision: Build a long-life, low-cost copper company with disciplined growth and strong returns for shareholders.
• Core values: Safety, operational excellence, sustainability, community engagement and prudent capital stewardship. See full details: Mission Statement, Vision, & Core Values (2026) of Ero Copper Corp.

• Asset structure: Operates integrated mines with on-site processing (SX-EW for cathode production where applicable, and concentrator plants for sulfide ore producing concentrates).
• Production chain: Exploration → mine development and drilling → ore extraction (open pit and underground) → crushing/grinding → processing → sale of copper cathode and concentrates.
• Cost focus: Emphasis on unit cost control via higher grades, mine sequencing, processing efficiency and local operating scale.

• Product sales: Revenues primarily from the sale of copper cathode and copper concentrates (pricing linked to LME copper prices, minus treatment & refining charges for concentrates).
• Production growth: Incremental revenue from higher throughput and grade improvements; brownfield expansions that increase payable copper sold.
• By‑products: Potential secondary credits (e.g., gold or silver) from concentrates that marginally offset cash costs.
• Cost control and margins: Cash margin is driven by realized copper price less site operating costs, sustaining and expansion capital.

• Commodity price risk: Revenues and profitability are sensitive to LME copper prices and concentrate sale terms.
• Operational risk: Mining and processing disruptions, grade volatility, and ramp-up risks for expansion projects.
• Political & permitting: Brazilian jurisdictional, regulatory and permitting considerations impact timelines and costs.
• Exploration & reserve replacement: Long-term value depends on successful exploration and conversion of resources to reserves.
