Toronto-headquartered Chantrell Ventures has until 23:59 on Thursday to amend its offer for junior gold miner and explorer Alexandria Minerals to match that of NYSE- and TSX-listed Agnico Eagle Mines. The board of directors of Alexandria has determined that the Agnico offer – announced nearly two weeks ago – constitutes a superior proposal than that of Chantrell and that it is entitled to terminate the agreement if it is not matched.
