Glamis Gold, Ltd. (“Glamis”), a Canadian mining company, brings this proceeding against the United States of America, claiming that the United States breached obligations owed to it under Chapter 11 of the North American Free Trade Agreement (“NAFTA”). In particular, Glamis claims that the United States expropriated rights possessed by Glamis to mine gold in southeastern California and that the United States denied Glamis fair and equitable treatment in its attempts to utilize those rights.
