Canada-based Yamana Gold has entered into an agreement to acquire all outstanding shares in Extorre Gold Mines for a total consideration of $404m.
Under the terms of the agreement, each Extorre shareholder will receive $3.50 per share in cash and 0.0467 of a common share of Yamana.
Extorre has also agreed to a $15m termination fee under certain circumstances, including acceptance of a superior proposal.
Extorre Gold Mines co-chairman Yale Simpson said, "The Cerro Moro project fits very well into Yamana's portfolio and Yamana has both the operational experience in Argentina and financial strength to develop the project on a timely basis."
The acquisition must be approved by at least 66.67% of Extorre shareholders and is also subject to other approvals, including court approvals and the receipt of all necessary regulatory approvals.
The transaction is expected to close in August 2012.
