Discovery studies Maun underground copper mine

"The positive results of this study are very encouraging. The study shows that a Zeta underground mine has the potential to add significant value to shareholders through increased operational flexibility and optionality in relation to the copper price, production volumes and extensions to mine life," said DML managing director Brad Sampson in a statement.

In addition, the scoping study has shown that the mine has a "very low" incremental development capital cost with attendant scope for rapid payback, Sampson added.
