[Brazil's CSN Mineração Cuts 2026 Iron Ore Production Guidance to 39–41 Mt and Suspends Low-Grade Ore Output]

Published: Sep 30, 2026 09:08 (GMT+8)
Brazilian iron ore miner CSN Mineração (subsidiary of Companhia Siderúrgica Nacional - CSN) disclosed in a regulatory filing that it has revised its 2026 iron ore production and third-party purchase volume guidance downward from 45.0–47.0 million metric tons (Mt) to 39.0–41.0 Mt. Concurrently, the company raised its 2026 C1 cash cost guidance from $22.0–$23.5/mt to $25.0–$26.0/mt. The revision stems from a temporary suspension of lower-grade iron ore processing at its Pires Complex dry processing plant and a reduction in third-party ore purchases, driven by margin pressure from elevated Brazil-China freight rates and challenging market conditions. CSN noted that the measure can be reversed if market conditions support stronger margins. [SMM Iron Ore]
