Mowana is an open pit mine. From 2009 to 2014 the mine had a very high stripping ratio averaging 20:1. From 2015 up to the end of the budgeted mine life in 2020 the strip ratio is expected to average 5:1. Plant capacity has steadily increased and will reach 1.4Mt/a by 2017. Costs and production from 2014 onwards are based on Wood Mackenzie estimates as the company is no longer listed on the AIM market and does not provide any operational guidance.
