Pan American Silver said Monday it plans to acquire Canadian silver and gold exploration company Minefinders for about $1.5 billion in a cash-and-stock deal that Reuters reports would help Vancouver-based Pan American more than double its production by 2015.

Skadden, Arps, Slate, Meagher & Flom corporate partner Riccardo Leofanti in Toronto is leading a team  advising Pan American on U.S. securities, antitrust, and tax issues related to the deal. The firm has handled work for Pan American—which operates mines in Argentina, Bolivia, Mexico, and Peru—in the past. Robert Pirooz is the company’s general counsel.
