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. In 2015 a new mining plan was proposed by Milpo to the government (under a self-sustaining private initiative included in the Peruvian Law) that included two stages of 40kt/d ore each stage. Since no mining activity is being carry out in the deposit this plan is just indicative of the economic potential of the project. ProInversion, the Peruvian agency to promote investment, was expected to re-privatise the Michiquillay deposit by the end of 2017.
