On 4th December 2007 it was announced that Australian company, Wolf Minerals LLC had acquired the rights to mine this deposit, and current plans are to reopen the site as a full-scale opencast metal mine for tungsten and tin, producing up to 3000 tonnes of tungsten metal per year.
The original name for the workings was "Hemerdon Bal", this was corrupted over time (possibly due to a mis-spelling on Ordnance Survey maps that remains to this day) to "Hemerdon Ball". The current owners refer to the deposit just as the "Hemerdon Mine".
