A Chilean court on Friday imposed a fresh freeze on sales of part of global miner Anglo American's
Santiago's 14th civil court issued an order prohibiting Anglo from selling a 49 percent stake in the southern properties, replacing an earlier injunction that was lifted.
Anglo American in London declined to comment on the sales freeze.
Anglo says the sale of a 24.5 percent stake in the assets to Mitsubishi for $5.4 billion (3.5 billion pounds) halved Codelco's option to buy a 49 percent stake in the properties. Codelco, which viewed the move as a snub, disputes that.
Anglo's properties in southern Chile include the flagship expansion project Los Bronces, where Anglo has invested around $2.8 billion; the El Soldado mine; the Chagres smelter; and the Los Sulfatos and San Enrique Monolito exploration projects.
Experts say Anglo American underestimated Codelco's ability to raise financing to buy the assets, and misjudged by investing billions of dollars to develop properties that Codelco had an option to buy into.
They also say Codelco was caught off guard by Anglo's decision to risk its standing in Chile by selling a stake to Mitsubishi -- which Codelco denies.
