London — Mayer Brown has advised Sumitomo Metal Mining Co., Ltd. (acting in a consortium with its partner, Sumitomo Corporation) on the acquisition of a 30 percent indirect interest in Compañia Minera Teck Quebrada Blanca S.A., which owns the Quebrada Blanca Phase 2 (QB2) project, from Teck Resources Limited for $1.2 billion.

The QB2 project is the second phase of the Quebrada Blanca copper mine in Chile.

The consideration payable by Sumitomo Metal Mining and Sumitomo Corporation consists of a $800 million earn-in contribution and a $400 million matching contribution made through a jointly held entity.
