Fire River Gold Corp. Announces the Completion and Commissioning of the CIL Circuit
March 20, 2012 Vancouver, Canada - Fire River Gold Corp. and Mystery Creek Resources Inc. (The Company) [TSX.V: FAU| OTCQX: FVGCF| FSE: FWR] is pleased to announce the completion of the CIL (Carbon in Leach) circuit construction. Commissioning is currently underway with assistance from Xstrata Process Support and Kappes, Cassiday & Associates. All supplies for the leaching circuit, including activated carbon and cyanide are currently on site. The five leach tanks are full of tailings slurry from mining operations. The reagents, including cyanide to start the leaching process, are scheduled for addition to the tanks before the end of this week.
With the operation of the CIL circuit, ore recovery will increase to +90% from the current 70%. Doré bars will be produced at site using carbon stripping and electrowinning.
Revenue from the CIL leaching circuit is projected to begin in April 2012 from freshly mined tailings, which are being produced at approximately 150 tonnes per day (tpd). The recovery of residual gold from the historic tailings pond has been scheduled to commence in April. The circuit was designed with a capacity of 250 tpd for the purpose of incorporating this additional supplemental feed. The historic tailings pond was estimated to contain 92,000 tonnes of indicated resources at a grade of 7.9 g/t gold plus 48,000 tonnes of inferred resources at a grade of 7.4 g/t gold prior to the addition of tailings from the 2011 and 2012 mining.
This milestone marks the completion of all pre-production projects for the Nixon Fork Mine.
