After several minor attempts, in 2008 Metals X Limited, a Perth-based mining company, through its subsidiary Bluestone Mines Tasmania Pty Ltd, the operator of the Renison Bell, one of largest tin mines in the world today, decided to mine the remaining tin at Mount Bischoff to blend with ore at its Renison Bell operation. A large open cut operation taking in all the old historic workings was developed at Mount Bischoff for this purpose with the ore being trucked to the Renison Bell processing plant. At the time ore reserves at Mount Bischoff were estimated to be grading at 1.20 percent tin. In 2009/10 of ore was mined at the Mount Bischoff open pit that produced of tin in concentrate. The open cut mine at Mount Bischoff is currently on care and maintenance. Bluestone Mines Tasmania Pty Ltd is continuing its exploration program at Mount Bischoff.
