Round Mountain’sparticipation hasearned it the twolargest awards inthe history of theSure Bet Program.Focusing on Energy Conservation: Sure Bet ProgramSince 2006, our Round Mountain operation in Nevada has participated in the SureBet Program, an energy conservation program offered by Sierra Pacific Power, thelocal energy provider for the mine. The program awards financial incentives annuallyto Sierra Pacific customers who can demonstrate significant results from energysaving improvements. Round Mountain’s participation has earned it the two largestawards in the history of the program.In 2006, <strong>Kinross</strong>’ Technical Services team, in coordination with Round Mountain’splant maintenance group, developed a business case for participating in the SureBet Program that required an up-front investment of $180,000 in new equipmentto lower energy consumption at the operation. The plan involved replacing four600-horsepower variable frequency drives with soft-start drives, and installing anoverflow bypass system in the mill that allowed the shutdown of a 50-horsepowerreclaim water pump. These improvements resulted in energy savings of 3.34 millionkilowatt hours and an award from Sierra Pacific of $100,000.In <strong>2007</strong>, <strong>Kinross</strong>’ Technical Services team, again in coordination with RoundMountain’s plant maintenance group, completed a plan to invest $1.08 millionin upgrades to the electric mining shovel fleet and to install more energy-efficientlighting. The upgrades included the replacement of 15-year-old analog drives inthree mining shovels with new digital drives, resulting in savings of nearly 30% inenergy consumed per shovel, in addition to improving shovel productivity. In total,the <strong>2007</strong> upgrades yielded additional annualized energy savings of 7.3 millionkilowatt hours and a cheque from Sierra Pacific for $202,824.Plans for 2008 at Round Mountain include additional upgrades to pump drives andlighting that could save 2.8 million kilowatt hours of electricity in addition to thereductions made in 2006 and <strong>2007</strong>.Page 55 <strong>Kinross</strong> <strong>2007</strong> corporate responsibility report
