All mineral reserves and mineral resources have been calculated in accordance with the standards of the Canadian Institute of Mining, Metallurgy and Petroleum and NI 43-101, other than the estimates for the Alumbrera mine which have been calculated in accordance with the JORC Code which is accepted under NI 43-101.
All mineral resources are reported exclusive of mineral reserves.
Mineral resources which are not mineral reserves do not have demonstrated economic viability.
Mineral reserves and mineral resources are reported as of December 31, 2009.
