Pogo Expansion

Primero are engaged by Northern Star Resources to implement the Pogo Mine process plant upgrades to increase throughput from 155 wst/h to 200st/h (220 peak). The main objective of the Pogo Expansion Project is to:

Increase milling capacity stepwise to a continuous 200 dry short tons per hour with peak 20 dry short tons per hour

Improve or hold metallurgical recovery and performance

Provide stability to process flows

Increase the level of automation

Reduce operator intensive duties (i.e. reagent mixing)
