SANTIAGO, Sept 9 (Reuters) - The agreement between Anglo

American and Teck brings together assets of

"extraordinary value," the chairman of Chile's state-run copper

producer Codelco, Maximo Pacheco, told Reuters on Tuesday.

London-listed miner Anglo American and Canada's Teck

Resources ( TECK ) announced their merger earlier on Tuesday, in what

would be the biggest mining sector M&A deal in over a decade.

Codelco is Teck's partner in Quebrada Blanca and Anglo

American Sur.

Anglo American and Teck operate adjacent copper mines in

Chile - Quebrada Blanca and Collahuasi - which are expected to

deliver them operational benefits.

Pacheco said that Chile is consolidating with this agreement

a global strategic leadership in copper.
