Inmet Mining Corporation (Inmet) (TSX: IMN) announces updated mineral reserves and resources as at December 31, 2012 as reported in the table below. Inmet-s share of consolidated contained metal in reserves and resources, net of 2012 mining, and on a pro forma basis reflecting a current 80% ownership of Cobre Panama, has changed from the reported Mineral Reserves and Resources as at December 31, 2011 as follows:
The main changes by individual mine or development property, net of 2012 mining, are as follows (on a 100% ownership basis) and quoted on a contained metal basis:
Cobre Panama
Las Cruces
Cayeli
Pyhasalmi
The year end 2012 mineral reserves and resources table is as follows:
TABLE 1
Notes to mineral reserves and resources table
Mineral reserves and resources are shown on a 100% basis for each property. Mineral resources are exclusive of mineral reserves, except for Cobre Panama.
Rounding as required by reporting guidelines may result in apparent summation differences between tonnes, grade and contained metal content.
The mineral reserve and resource estimates are prepared in accordance with the CIM Definition Standards On Mineral Resources and Mineral Reserves, adopted by CIM Council on November 14, 2004, and updated November 27, 2010 and the CIM Estimation of Mineral Resources and Mineral Reserves Best Practice Guidelines, adopted by CIM Council on November 23, 2003, using geostatistical and/or classical methods, plus economic and mining parameters appropriate to each project. You will find the definitions and guidelines at .
Estimates for all operations are prepared by or under the supervision of a qualified person as defined in National Instrument 43-101 (usually an engineer or geologist).
There are no known environmental, permitting, legal, taxation, political or other relevant issues that would materially affect the estimates of the mineral reserves.
Mineral resources which do not form part of the mineral reserves do not have demonstrated economic viability.
The Qualified Persons identified below have reviewed the technical content of this release.
Mineral resources as at August, 2012, were estimated by Robert Sim, P. Geo., of SIM Geological Inc. Mineral reserves as at December 13, 2012 were estimated by William Rose, P.E., of WLR Consulting, Inc., a qualified person under National Instrument 43-101. Both mineral reserves and mineral resources remained unchanged at December 31, 2012.
Reserve estimates are based on the following assumptions:
Mineral resources include mineral reserves.
Resource grades are estimated using ordinary kriging with a nominal block size of 25 metres by 25 metres by 15 metres. Resources are limited inside a pit shell defined by a copper price of US $2.60 per pound, $1.75 per tonne mining cost, $7.02 per tonne total site operating cost, and are tabulated at a cut-off grade of 0.15 percent copper.
Mineral resources as at December 31, 2012, were estimated by Robert Sim, P. Geo., of SIM Geological Inc. Mineral reserve estimates as at December 31, 2012 were prepared under the supervision of Joseph Boaro, P. Eng. (Director, Mining, Inmet Mining).
Resource estimates for the gossan material are based on a cut-off grade of 1 gram per tonne gold.
Resource estimates for the primary sulphide material are based on a cut-off grade of 1% copper equivalent (CuEq) based upon the following formula:
CuEq = (Cu% + (Zn% x 0.360) + (Pb% x 0.360) + (Ag gpt x 0.0106))
Resource estimates include only material in addition to those used to generate reserves and are based on the same metal prices and a lower net smelter return cut-off: US $59 per tonne.
Mineral reserve and resource estimates as at December 31, 2012 prepared under the supervision of Timo Maki, EurGeol., European Federation of Geologists (Chief Geologist, Pyhasalmi).
Mineral reserve estimates are based on the following assumptions:
Resource estimates are based on the geological limits of the massive sulphides.
