The Racecourse Orebodies at Mount Isa consist of a series of parallel steeply dipping lead/zinc/silver orebodies with a strike length of up to 1000 metres. Production from these orebodies between 13 Level to 9 Level has been by a series of cut and fill stopes in two level stages, leaving a crown pillar at 11 level. Development of the 15 level to 13 level extraction stage has recently been completed._x000D_
The layout consists of a series of parallel stopes over a strike length of 1200 metres._x000D_
Access to the stopes is by two declines connecting the stopes with a series of crosscuts This paper describes the basic layout with development and production methods employed.
