reports an overall processing cost <strong>of</strong> $35/t.<br />

3.1.5.6 Worker's Camps<br />

<strong>Polymetals</strong> currently operates a small, serviced camp in Canbelego for company geologists and mine<br />

caretakers. The project had allowed for the relocati<strong>on</strong> <strong>of</strong> a 60-pers<strong>on</strong>, camp from White Dam to Canbelego<br />

for Mt Boppy workers. Due to the imminent sale <strong>of</strong> the White Dam asset this camp is no l<strong>on</strong>ger available.<br />

AMC added a capital cost c<strong>on</strong>tingency to address the requirement to purchase a new camp. An appropriate<br />

site has been selected.<br />

A camp for the mining c<strong>on</strong>tractor will also be located in Canbelego.<br />

3.1.5.7 Water Supply<br />

Mt Boppy is in a regi<strong>on</strong> <strong>of</strong> very low rainfall (approximately 300 mm per year) therefore the mine must rely <strong>on</strong><br />

bore water for processing. The plant requires 450 ML/pa <strong>of</strong> make-up water, however <strong>on</strong>ly 240 ML/pa is<br />

available under the existing permit. Currently the intenti<strong>on</strong> is to bridge the shortfall by dewatering the pit.<br />

<strong>Polymetals</strong> state that the inventory currently in the pit together <strong>with</strong> future inflow will be adequate for the<br />

2-year life <strong>of</strong> the mine.<br />
