Ramelius Resources' board has approved a new mine plan for the Wattle Dam underground gold mine near Kambalda in Western Australia.
The firm will mine a total of 216,000 tons of ore from the mine's Block D and 129,000 tons of ore from Block C.
The firm is expecting steady production from the mine until the end of 2013.
Based on the diamond drill results, the mineralisation in Block D will be similar to that of Blocks A and B, which have over 20g/t to the end of March.
Block C is expected to have a lower grade as there have not been as many visible gold intercepts in this area.
