Ero Copper (TSX:ERO)

Overview: Ero Copper is a Vancouver based miner focused on copper projects in Brazil, primarily its Caraíba operations in Bahia State, where it produces and sells copper concentrates with gold and silver as by products.

Operations: The company generates its revenue mainly from Caraíba in Brazil at about US$413.5m, alongside contributions from Tucumã at about US$317.4m and Xavantina at about US$193.0m.

Market Cap: CA$4.3b

Ero Copper is attracting attention because its Brazilian copper operations are ramping up after major upgrades. Recent Q1 2026 results show profitability with net margins at 31.6% and high returns on equity. At the same time, the stock carries tension points, including high debt, concentrated exposure to Brazil and execution risk as projects like Tucumã and the Furnas Copper Gold Project scale. For investors looking at copper exposure linked to electrification and green energy trends, Ero Copper presents a mix of recent earnings momentum and operational and balance sheet risks that may warrant closer examination beyond the headlines.

Ramping Brazilian copper output and 31.6% net margins can mask as much as they reveal. Before you lean in, review the 4 key rewards and 2 important warning signs that could change how you see the next phase.

Freeport-McMoRan (FCX)

Overview: Freeport-McMoRan is a Phoenix based mining company that produces copper, gold, molybdenum, silver and other metals from large scale assets across North America, South America and Indonesia, including its flagship Grasberg district in Indonesia and multiple major copper mines in the United States and Peru.

Operations: The company generates revenue across several segments, led by Indonesia Operations at about US$8.1b, U.S. Rod & Refining at about US$7.3b, United States Copper Mines including Morenci at about US$7.9b combined, Cerro Verde in South America at about US$5.0b, Atlantic Copper Smelting & Refining at about US$3.4b, and Molybdenum Mines at about US$0.8b, partly offset by about US$7.1b from Corporate, Other & Eliminations.

Market Cap: US$98.3b

Freeport-McMoRan gives you direct exposure to large, long life copper assets at a time when electrification, AI infrastructure and grid upgrades are all metal hungry, while also earning from gold, molybdenum and smelting. The new Indonesian smelter and precision leaching projects are aimed at lowering unit costs and lifting margins, and recent quarterly results show higher sales, earnings and cash returns via dividends and buybacks. At the same time, the stock is priced on a rich P/E versus peers, relies heavily on Indonesia and carries funding risk because all liabilities come from external borrowing. The key consideration for investors is whether its growth projects and U.S. copper premium can justify that valuation and risk mix over time.

Freeport-McMoRan’s rich P/E and large copper footprint keep investors focused on the headline story. However, the real swing factor may be how the projects compare with expectations in the analyst forecasts for Freeport-McMoRan that most people have not fully unpacked yet.

Capstone Copper (TSX:CS)

Overview: Capstone Copper is a Vancouver based miner that produces copper and other base and precious metals from operations in the United States, Chile and Mexico, while also advancing new projects across those regions.

Operations: Capstone Copper generates most of its revenue from Mantoverde at about US$1.1b and Mantos Blancos at about US$678.1m, with additional contributions from Pinto Valley at about US$465.6m and Cozamin at about US$317.9m, partly offset by about US$51.9m from Other.

Market Cap: CA$11.0b

Capstone Copper stands out in this screener because it couples large producing assets with project expansions that are aimed at lifting volumes and improving unit costs. A net debt to EBITDA ratio of 1x and growing free cash flow give it room to fund more of that growth internally. Earnings growth over the past year has been very large, margins sit at 17.1%, and Q1 2026 swung from a loss to a US$102.46m profit, which shows how operating leverage is starting to work when mines are running well. The flip side is real, concentrated risk around water constraints at Pinto Valley, project execution at Mantoverde Optimized and Santo Domingo, and potential regulatory shifts in Chile that could affect permits, taxes and future project timing.

Capstone’s accelerating free cash flow and 17.1% margins could be masking where the real upside sits. Get the full story in the analyst forecasts for Capstone Copper before water and permitting risks rewrite the script.
