It is expected that once the higher grade production from the North Renison area commences, operating costs will further decline as a result of the higher tin production. The company expects to achieve its targeted mine productivity of 60,000 tonnes of ore per month and 8,000 tonnes of tin in concentrates per annum when mining fronts are fully established in both the North and South Renison declines in early 2012. 

Another major milestone in the tin concentrator was the commissioning of the copper circuit enabling copper to be recovered as a co-product from the tin concentration process. Approximately 94 tonnes of copper was produced for the year and the circuit has now been fully commissioned. Copper in concentrate is now being output at a rate of approximately 500 tpa and is expected to increase further as higher grade coincident copper areas are mined. 

During the year a core focus of BMTJV was on mine exploration. Two diamond drills continuously focussed on the task of upgrading and extending the Resources and Reserves of the mine. A third diamond drill rig operated on the surface with a focus on open pittable surface targets within the mining lease. Over 33,000m of diamond drilling was completed during the year. 

The exploration outcomes resulted in an increase in the Total Identified Mineral Resource Estimate (as of 30 June 2011) to 8.35Mt @ 1.63%Sn containing 135,3790 tonnes of tin and underground mining reserves alone were increased to 2.61Mt at 1.43%Sn containing 37,202 tonnes of tin.
