Fire River Gold Up DATE
Fire River Gold Up DATEFire River Gold Starts Up the Nixon Fork Mill
July 5, 2011 Vancouver, Canada -- Fire River Gold and Mystery Creek Resources (collectively "the Company") are pleased to provide the following update for the Nixon Fork Mine. It is a thorough document that provides insight into all aspects of operations at site. All photos contained in this release were recently taken and represent current conditions at site.
Start Up Schedule
The mill was started up on July 4th. Only the gravity and flotation circuits are being run, which will achieve approximately 80% recovery of gold from freshly mined ore.
The crushing circuit has already been operating this past week as a commission task and to prepare road surfacing material for construction. See Figure 1 for a picture of the primary jaw crusher in operation.
The start up plan for the plant is to process barren waste for a few days to get the material flowing through the mill. Next, low grade mineralized rock (2 to 8 g/t) will be processed over the next week as a "breaking in" period for the gravity and flotation circuits. After the breaking in period, the mill should be fully operational on gravity and flotation circuits and will start processing higher grade feed.
Completion of the cyanide-in-leach (CIL) circuit will be ongoing during start up, with mechanical completion and commissioning projected for late fall. Adding the third process should bring total recovery up to 96%.
The mine and mill should be fully operational and near capacity at 150 tpd of fresh ore from the mine by the end of October. By late spring of 2012, ore feed from the mine will be supplemented by recovering an additional 100 tpd of tailings from the existing tailings pond, which grades approximately 7.6 g.t (Giroux, 2010).
The key project objectives dates are summarized as follows:
- July 4 - Mill start up
- Late July -- First concentrate shipment of 30 tonnes from Anchorage
- Mid to late August -- First doré gold pour from gravity concentrate
- Early September -- Dry stack construction completion
- September/October -- Mechanical completion of CIL plant
- Late October -- Commissioning of CIL, start of leaching
- Late Spring 2012 -- Leaching historic tails from pond
