The battery, furnaces and Chilean mills which survive on the site suggest that the chlorination process was used to assay pyritic ore. The works subsequently incorporated the cyanide process after its introduction to Victoria in the late 1890s. Upon Jeremiah's death in 1917, the works continued to be run by one of his sons, Herbert. Herbert Archbold went on to become widely known throughout Victoria for his cyaniding expertise. Herbert died in 1966 and the property was bought by his son Harry. When Harry Archbold died in the late 1980s the treatment works was closed and everything left as it was. https://vhd.heritagecouncil.vic.gov.au/places/7899/download-reportNineteen page document.

These certificates were awarded in 3 classifications:- 1st class certificate holders could manage any mine where large and expensive machinery was used. They needed knowledge and competence in areas such as surveying, underground plan drawing, ventilation, amalgamation, retorting and smelting.
