How Ero Copper (ERO) Is Using Furnas Drilling to Build a Longer-Term Copper Growth Case

Ero Copper Corp. (NYSE:ERO) is one of the best copper stocks to buy for the AI and electrification boom. On June 10, 2026, the company reported new assay results from an additional 24,000 meters of drilling at its Furnas Copper-Gold Project in Brazil. Ero said it had completed more than 75,000 meters of drilling through the end of May, with 10 drill rigs operating at the project and the deposit still open to depth and along strike.

The update strengthens Ero’s long-term copper growth case at a time when electrification, grid investment, and AI-related power demand are keeping copper supply in focus. Furnas is still a development-stage asset, but Ero said permitting, engineering, metallurgical, geotechnical, hydrogeological, and environmental workstreams are advancing toward a pre-feasibility study expected in 2027. That gives the stock a copper expansion angle rather than direct data-center exposure.
