New ore sorter helps Minsur production

2016/8/19      view:

    The start-up of a new ore sorter at Minsur's San Rafael mine in Peru is helping keep the company on track to meet 2016 production and cost reduction targets. The new operation, commissioned in May, sorts low grade ore which had previously been stockpiled for treatment at the end of the mine's life.

    Production of tin-in-concentrate at San Rafael in April-June declined by 8% year-on year to 4,573 tonnes, with a decline in average head grade to 2.03% more than offsetting a 3% increase in ore treated as a result of the start-up of the new plant. First half year production declined by 7% to 8,847 tonnes, while refined tin production at the integrated Pisco plant declined by 5% to 9,281 tonnes, helped by a reduction in concentrate stocks. In a release Minsur said that the latest data is in line with the mine plan and production guidance of 20,000 – 21,000 tonnes for 2016.

    Cash costs per tonne of ore have fallen 20% year-on-year to US$109/t, dropping further to $103/t in Q2. Target for the year is $115 – 125/t, compared to $127/t in 2015 and $143/t in 2014. Cash costs per tonne of refined tin declined by 10% to $8,048/t in the first half, helped mainly by cost saving initiatives introduced last year, including the adoption of four production hubs within the mine which have reduced metres of underground tunnelling required.

    Minsur will release consolidated results for its operations in Peru and Brazil on 12 August.
