Creighton Deepening Project: Two projects are underway to allow deeper mining at Creigton Mine. The first is an $8-million, four-year diamond drill exploration program that will allow for ore tonnage to be defined down to the 10,000-foot level. The second is a $48-million expansion project that will establish production ore at the 7,810-foot level and bring 1.8 million tons of high-grade ore into production from 2006–2011.
