Argyle currently operates an open pit mine to recover diamonds from the AK1 lamproite pipe. In addition, alluvial mining has been an important part of Argyle's history. Commencing in 1983 the alluvial operations involved the mining of ancient creek beds where diamonds have been washed down over millions of years. Today the Argyle mining operation comprises an open pit which will continue until around 2010. The ore body continues at depth, and for this reason an underground mine is being developed that will extend the life of the mine to at least 2018.
