The company has made further progress in its development with the 1.2 million tonne per annum processing facility scope 90% complete and commissioning of the power station underway.
Dry commissioning of the crushing circuit will begin this week followed by sequential wet commissioning of the mill, other key componentry and the carbon in leach circuit in January 2013.
Procurement of stores, insurance spares and other consumables is well advanced.
Existing surface stockpiles, outside of the current resource, totalling 190,000 tonnes at 1 gram per tonne (g/t) for 6,000 contained gold ounces have been identified and are being moved to the run of mine stockpile.
Some of this material will be used for mill feed during the commissioning period followed by feeding of the higher grade open pit ores.
The first gold pour is set to occur after allowing for a build-up of gold in circuit stocks.
The remaining construction requirements for the processing facility are being completed concurrently with the commissioning activities, and following practical completion the project will be handed over to the operations team who will progressively transition from commissioning to full scale operations.
Les Davis, managing director, commented: "We are looking forward to commissioning the Murchison gold project, bringing it into production and ramping up to 100,000 ounce per annum rates on time and in line with budget.
In the Murchison, Silver Lake is developing a second gold mining operation with multiple mines feeding a central processing facility.
The Murchison gold project has a current resource of 25.3 million tonnes at 2.8g/t for 1.9 million contained gold ounces.
Production is expected to begin in the March 2013 quarter ramping up to 100,000 ounces per annum in 2014.
The base case production plan has ore being sourced from 14 open pit and four underground mines at various stages over an eight to 10 year mine life.
The design of the gold processing facility has made allowance for the later addition of a base metals grinding and recovery circuit.
