Gold mineralization in the Magdala deposit at Stawell is hosted within deformed turbidites and the underlying mafic volcanic successions. This setting is atypical when compared to the slate-hosted gold deposits elsewhere in the Lachlan orogen.

Note: the 'Hangingwall reefs' are high-grade auriferous quartz lodes that occur in the upper levels of the Magdalena mine (Henry et al., 2006).
Gold was produced from these reefs in 1856-1880.
