The Deborah Company Quartz Gold Mine consists of a steel poppet head, sets of concrete engine beds, concrete foundations of a workshop and a 20-head crushing battery. The Deborah Company's operations on the site span the period 1932-50, when the mine was one of the most successful of Bendigo's (and Victoria's) 1930s mining revival. The mine and the machinery were subsequently purchased by the adjoining North Deborah Company, which worked it until 1954. It appears that crushing continued to be carried out at the battery until the early 1960s. The shed and crushing machinery plant presently on the site are the former Golden Square government battery, which was relocated to the site in 1996.
The Deborah Company Quartz Gold Mine is of historical, archaeological and scientific importance to the State of Victoria.
The Deborah Company Quartz Gold Mine is historically and scientifically important as a characteristic example of an important form of gold mining. Gold mining sites are of crucial importance for the pivotal role they have played since 1851 in the development of Victoria. As well as being a significant producer of Victoria's nineteenth century wealth, quartz mining, with its intensive reliance on machinery, played an important role in the development of Victorian manufacturing industry. The Deborah Company Quartz Gold Mine is important as a manifestation of this facet of gold mining.
The Deborah Company Quartz Gold Mine is also historically significant in association with the North Deborah Mine to the south, and the Central Deborah Mine (also to the south): jointly they form the only example in Bendigo where the once-common spectacle of poppet heads marking out a line of a reef, can still be observed.
The Deborah Company Quartz Gold Mine is scientifically important due to the survival of the steel poppet head and a comprehensive array of foundations relating to one of Bendigo's most important twentieth-century mines. The site is archaeologically important for its potential to yield artefacts and evidence which will be able to provide significant information about the technological history of gold mining.
