The deal is expected to be completed in the first quarter of 2022.
As part of the transaction, Trafigura will retain the life-of-mine 100% offtake agreement for copper concentrates from Matsa.
Matsa owns the Aguas Teñidas, Sotiel and Magdalena mines in southern Spain, which produce copper, zinc and lead concentrates, with silver by-products.
Sandfire operates the DeGrussa copper-gold mine, located 900km north of Perth in Western Australia, which produces high-quality copper-in-concentrate with significant gold credits.
Spot trading was quiet in China’s copper concentrates market in the week to last Friday September 17 ahead of China’s Mid-Autumn festival on September 18-21.
Fastmarkets' copper concentrates TC/RC index, cif Asia Pacific was, therefore, unchanged at $60.1 per tonne, or 6.01 cents per pound.
Australian mining and exploration company Sandfire Resources will buy Spain's Minas de Aguas Teñidas (Matsa) for $1.87 billion from Trafigura and the Mubadala Investment Co, the company said on Thursday September 23.
