Martha Underground Mine
Work on Project Martha began in 2019. The project has two parts:
-
A layback of the Martha north wall, removal of the slip material and construction of a new haul road.
-
An underground mine mainly below the Martha Open Pit which is accessed from the existing Favona portal. A small orebody called Rex, is located below residential properties around Mueller Street and Gilmour Streets, north of Kenny Street.
The estimated project life is around 10 years. Underground mining of the Rex orebody will occur during approximately three of those years.
The consent conditions are similar to those that apply to the Correnso Underground Mine and our previous operations in the Martha Open Pit.
