Abstract	Gold was discovered in the Mt Magnet district in 1888, with lode mining commencing in 1891 and has continued almost uninterrupted to the present with more than 7 t of Au won from the district. Many of the individual workings are small, but 17 of the deposits have produced over 40 kg of Au. Mineralization in banded iron formations accounts for 80% of the production, with more than half from the Hill 50 deposit alone (Thompson et al., 1990). However, 20% of the Au in the district occurs within quartz±carbonate±tourmaline veins as in the Parkinson Pit (subsequently renamed Star Pit) in the North Morning Star area (Wilson, 1990; Figure 1). The Parkinson mineralization was discovered during 1986 by Metana Minerals NL. This followed a programme of 10 x 6 m grid drilling in some relatively small leases, E of the Hill 50 Mine leases, which were acquired from prospectors in 1985. Mining commenced in 1987 with an initial resource of 3.1 Mt at 3.2 g/t Au to a depth of 100 m (i.e., essentially the regolith resource) providing a minimum 5 year mine life (Wilson, 1990). Subsequently, the Parkinson Pit was amalgamated with the adjacent Hill 50 Pit and mining was extended into fresh rock.
