Name and Location
Mt Carlton gold/silver/copper mine project, Queensland, Australia.

Client
Evolution Mining.

Project Description
Mt Carlton has a total gold reserve of 9.13-million tons at a grade of 2.8 g/t, and a silver and copper reserve of 10.2-million tons grading 47 g/t silver and 0.27 g/t copper.

The project is expected to produce 720 000 oz of gold, 14.4-million ounces of silver and 25 000 t of copper over an initial 12-year mine life.

Mining production is derived from two pits, V2 and A39, using conventional drill-and-blast and load-and-haul methodologies. These functions are undertaken by contractors, mining 5 m benches in 2.5 m flitches. The A39 pit will have a life-of-mine strip ratio of 3.3:1. The V2 pit will have a life-of-mine strip ratio of 2.7:1 and will be mined over nine years.

The low-grade ore will be stockpiled and processed after the depletion of the high-grade ore, to be processed after the completion of openpit mining.

Ore will be processed through conventional technology, consisting of crushing, grinding and flotation to produce a polymetallic concentrate. The processing plant will have a throughput capacity of 800 000 t/y.

Value
A$170-million.

Duration
The Mt Carlton mine was expected to be officially opened on April 10.

Latest Developments
First concentrate from the silver-rich A39 deposit was achieved in March 2013.

The site team is focusing on ramping up the plant to full capacity, which is expected to be achieved on a sustainable basis in the September 2013 quarter.

Key Contracts and Suppliers
None stated.
