Abstract

The Pogo gold mine, in Interior Alaska, U.S.A., is operated by Sumitomo Metal Mining Pogo LLC (SMM Pogo LLC.). It has been developed since 2006 and is considered a relatively “young” mine. Continuous, near mine exploration has been needed to add additional resource and reserve because the original life of mine was a short 10 years (assumed from initial feasibility study). Since 2009, when the operatorship was changed to SMM Pogo LLC. from Teck Resources Ltd., exploration has been concentrated in the vicinity of current mine area. The reason for this was to minimize the preparatory period of development in the case of discovery of additional feasible ore bodies. As a result of the drilling program from 2009 to 2011, based on the strategy above, the new E1 ore body was discovered in East Deep area, 400 m northeast of the developed Liese Zone. The E1 vein added 1,283 koz. (40 tonnes) gold and contributes more than 2 years extension to life of mine. This was achieved by clear strategy, prompt analysis of drilling results and its reflection to geological model and flexible exploration planning.
