Minsur considers investing between USD 1.5 billion and USD 2 billion in Peru and Brazil in the next seven years. The firm wants to increase annual tin production by between 6,000 and 7,000 tonnes as of 2017 through waste treatment at its San Rafael mine in southern Peru. The project is subject to pre-feasibility studies. It also wants to build the Mina Justa copper mine in Ica region, which could reach peak production in 2020.

For the year 2013, the company expects to produce 30,000 tonnes of tin, similar to 2012.
