CSN Mineracao revises 2026 production guidance to 39.0-41.0 mt from 45.0-47.0 mt and increases 2026 C1 cash cost guidance to $25.0-$26.0/ton from $22.0/ton-$23.5/ton, citing lower-grade ore output reduction at the Pires complex due to more challenging market conditions, including higher freight costs.
