Key Facts
- —Where this is Mina de Fábrica is an iron ore mine at Ouro Preto, in Minas Gerais, Brazil’s mining state.
- —What happened On 25 January 2026, about 263,000 cubic metres of sediment-laden water overflowed a pit into two rivers.
- —The damage The state environment secretary reported lost biodiversity, silted rivers and contaminated riverbank forest. Vale said nobody was hurt.
- —The decision The Minas Gerais state court allowed a partial restart, under a compliance agreement with prosecutors and the state government.
- —The catch Only part of the mine restarts, and only while licences and conditions hold. Vale says output guidance is unchanged.
- —Why it counts In Brazil, after Mariana and Brumadinho, a court decides when a stopped mine may run again — not the miner.
Eight months after a pit overflowed into two rivers, a state court has let Brazil’s biggest miner switch part of the site back on.
A Minas Gerais court has cleared the Vale Mina de Fábrica restart, and the company began partial operations on 23 September 2026. The mine had been shut since January, when water and sediment escaped a pit.
What Vale actually announced
Vale said on 23 September 2026 that it had begun a partial resumption at Mina de Fábrica. The state court had given its authorisation.
The clearance rests on a Termo de Compromisso, a formal compliance agreement signed with Minas Gerais prosecutors and the state government.
Only part of the operation restarts. Vale must keep its licences and conditions in force and carry on with the actions the agreement sets out.
The company said the restart does not change its current production guidance.
Why the mine stopped in the first place
The mine stopped on 25 January 2026. About 263,000 cubic metres of water mixed with sediment escaped a pit at the site.
It reached the Goiabeiras and Maranhão rivers and spilled onto neighbouring ground operated by CSN Mineração.
Vale said nobody was injured. João Lobo, the state environment secretary, reported lost biodiversity, silting and damage to riverbank forest.
Those two statements are not in conflict. One is about people, the other about the river.
CSN Mineração, whose ground the water reached, is a separate miner. The overflow therefore crossed a company boundary as well as a river.

The Vale Mina de Fábrica restart in context
Vale S.A. is a Brazilian mining company and one of the world’s largest iron ore producers. Its shares trade in São Paulo under the ticker VALE3.
The Vale Mina de Fábrica restart matters to the company’s operations, but it is not a macro event for Brazil. Vale said the partial restart does not change its current production projections.
The available reports do not give the mine’s annual capacity or tonnage. They also do not state the exact date of the TJMG decision or reproduce the full text of the court’s order.
What is clear is the legal architecture: a state court, a state prosecutor’s office and a state government, all inside Minas Gerais. The available reports do not name a federal ministry as the deciding authority.
What the conditions mean day to day
The Termo de Compromisso is not a one-off permission slip. It is an ongoing agreement, and Vale said its actions under it continue.
Vale said the actions provided for in the Termo de Compromisso will continue alongside the partial resumption. The reports reviewed do not specify which inspections, reports or checks the agreement expressly requires.
The company framed the restart as consistent with its guidance. It did not announce new spending, new jobs or a change to its sales targets.
The partial restart is not a return to full operations. Reports do not say what it does to site output.
Why this matters to expats and investors
Anyone holding Vale shares, directly or through an emerging-market fund, is exposed to Brazilian court decisions. This week’s decision is a modest positive, not a clean bill of health.
The wider signal is procedural. Here the court authorised a partial resumption under a Termo de Compromisso.
Vale, state prosecutors and the state government are all parties to that agreement.
That structure raises the cost of doing business, but it also makes outcomes more predictable for those who follow the filings. Compliance news now shapes Vale’s story alongside price headlines.
For foreign residents in Minas Gerais the read is narrow. A suspended mine is moving again under supervision, and the conditions still bind Vale.
What to watch next
The key test is whether the partial restart holds without new incidents or new court orders. Vale has not published a timeline for returning to full capacity.
Watch the Termo de Compromisso for any public updates from Minas Gerais prosecutors. Those documents, not press releases, will show what conditions are being enforced.
Watch Vale’s quarterly production reports for any mention of Mina de Fábrica. If the partial restart expands, it should appear there first.
Vale reported a partial resumption authorised by the court. It is subject to the safety, environmental and licensing conditions in its statement.
The Vale Mina de Fábrica restart is conditional, so the thing to watch is whether the conditions hold. A breach would put the clearance back before the same court.

Frequently Asked Questions
Did Vale get full approval to restart Mina de Fábrica?
No — Vale said it began a partial resumption, not a full restart. It must respect safety, environmental and licence conditions.
Which court authorized the restart?
The Tribunal de Justiça do Estado de Minas Gerais (TJMG), Minas Gerais’s state court of justice. Reports do not give the exact date of that decision.
Why was the mine halted?
A water-and-sediment overflow was recorded at the complex on 25 January 2026; TJMG suspended all mining activities there on 6 February 2026. Resumption was subject to technical proof of stability and safety.
