The project assumes an open pit and conventional copper-moly concentrator. An old plan indicated a mill of 65kt/d that would double its capacity after the 5th year. Later on Nexa resources (before Milpo) was proposing development of this project in two stages of 40kt/d ore each. After Southern Peru won the privatisation of Magistral in 2018, this proposed option to 80kt/d ore in two stages is not longer applicable. We believe that Southern will go directly of a much higher economic of scale. We are conservatively estimating a mine-mill capacity of 100kt/d ore.
