Following Phase 1, the capacity of the new concentrator will be 95,000 tonnes of ore per day, producing on average approximately 170,000 tonnes of copper equivalent (copper, gold and molybdenum) a year over the first ten years of operation. This is expected to move Centinela towards the first cost quartile of global producers.

Recall that when copper mines were being commissioned a decade ago, the capital intensity for new copper projects was about $10,000/t. The average monthly copper price per tonne topped out in 2011 at $8,828/t. In other words, despite a record-high copper price that year, the capex cost to mine a tonne of copper exceeded the price received.
