Revett Minerals Inc.

This represents an increase in proven and probable reserves of 3,400,530 tons or 39.3%, excluding the reserves mined during 2005. At planned production rates of 6,500 tons per day, the increase in reserves represents an increase in the operating life of the Troy Mine of approximately 1.4 years. This would correspond to an increase in the remaining mine life to 5.1 years. As at December 31, 2004, the estimated reserve life at the Troy Mine was approximately 3.5 years.

As at December 31, 2005, the estimated reserves at the Troy Mine are calculated to be 12,061,649 tons grading 1.41 ounces per ton silver and 0.60% copper, using a cutoff grade of US $12.00 net smelter return per ton. These reserves were calculated by Mr. Larry Erickson, P Eng., a Qualified Person in accordance with National Instrument 43-101.
