Dentons and White & Case have grabbed lead roles advising a consortium of state-owned Chinese companies on their acquisition of a Peruvian copper mining project from Glencore Xstrata for $5.85 billion. It’s one of two major M&A deals that Glencore announced Monday.

The sale of the Las Bambas project to a group led by Melbourne-based MMG Ltd., a subsidiary of metals and mineral trading company China Minmetals Corp., comes almost a year after Glencore Xstrata was formed via the $65 billion merger that joined the two legacy companies.
