The Fuerabamba community has submitted a legal claim to the local judge of Cotabambas in Apurimac, Peru.

The town of Nueva Fuerabamba near Las Bambas was built for the community in consideration for their land being used for the mine.

The legal claim seeks to nullify the agreements between the community and Las Bambas in relation to the transfer of land, cancel the registration of the land, and seek damages for losses suffered by the community.

The claim is for 1.5 billion Peruvian soles, equivalent to about US$450 million.

MMG said it regarded the claim as "unfounded and opportunistic" and would vigorously contest it.

The company has faced community issues in the past, with protests blocking a road.

A state of emergency has been in place for much of this year along the logistics route between the mine and railway.

Las Bambas is one of the world's largest copper mines, producing 186,637 tonnes of copper concentrate in the first half of 2018.

The mine is slated to produce 410,000-430,000t of copper at C1 costs of $1-1.10 per pound this year.

MMG also revealed this week that it had filed two formal claims in the UK High Court of Justice, totalling $31.5 million for indemnities relating to tax matters relating to previous owner Glencore.

Late last month, the court handed down its decision, providing that a significant proportion of the amounts claimed are recoverable from Glencore but only upon the conclusion of Tax Court appeals in Peru.

MMG chief financial officer Ross Carroll described the potential outcome as "immaterial".

Shares in MMG remained untraded in Australia at A$5.
