Joint venture partners AngloGold Ashanti and Independence Group have approved a $79.3-million investment to develop the Boston Shaker underground project, at the Tropicana gold mine, in Western Australia.
The ore from the underground mine would enable Tropicana production to be maintained at between 450 000 oz/y and 50 000 oz/y over the next five years, and would increase the average to 480 000 oz/y over the period.
