Total Inferred Resource
This Mineral Resource at December31, 2013 has been derived and verified by independent geologist Malcolm Titley of the consulting group CSA (Global) London UK, a qualified person and holds the following valid qualifications: BSc (Hons) Geo, MAIG, and FAusIMM. This depleted resource was derived and verified in conjunction with David Gray of First Quantum who is a qualified person and holds the following valid qualifications: BSc(Hons)Geo, MAusIMM, and Pr.Sci.Nat.
Current surface stockpiled ore has been excluded from the resource estimate. Stockpiles have increased during 2013 and at year end totalled 44.3 M tonnes @ 0.70 %TCu, 0.13 g/t Au.
The classification of the Mineral Resource is based on the relative distribution of the copper mineralization. The increased quantity of the gold assays that are now contained within the Kansanshi drill hole database allows for the classification of gold mineralization to be aligned with the copper mineralization.
