Grupo Mexico SAB, Mexico's largest mining company, said it will appeal a ruling ordering it to deliver to Tucson-based Asarco LLC a 29 percent stake in Southern Copper Corp., and dividends paid out on those shares.
The ruling of U.S. District Judge Andrew Hanen is "incorrect," Grupo Mexico said Friday in an e-mailed statement.
Lawyers for Asarco estimate the Tucson mining company stands to receive about $6 billion in cash and stocks because of the ruling.
