New Bendigo Gold Project

摘要

The Bendigo goldfield is centred on the urban area of Bendigo (population approximately 60 000) in central Victoria, 130 km north west of Melbourne, Australia (Figure 1). Gold was discovered at Bendigo in 1851 and production continued through to 1954. The Bendigo goldfield is the second largest goldfield in total gold produced in Australia, after Kalgoorlie's Golden Mile with a total production of 22 million oz (Figure 2). The geology of the Bendigo Field consists of a series of tightly folded, interbedded sandstone and shale sediments. Within the sediments the gold mineralisation is hosted in quartz reefs or ribbons closely associated with anticline axes and reverse faulting (Figure 3). The gold within the quartz reefs is typically both coarse grained and erratically distributed.
