Snapshot	Mining has now concluded at the Vivien Gold Mine with the last ore load coming to surface on 11 January 2023. By the end of January 2023, all stockpiled ore had been hauled to, and milled at, Mt Magnet. In early February 2023 all items of plant, equipment and infrastructure were demobilised, and the site was placed on care and maintenance.

Summary:

Vivien is a typical orogenic structurally controlled Archaean gold lode system.

Mineralisation occurs within a high-grade quartz vein, hosted by a dolerite-gabbro unit. The veins trend 028° magnetic and dips steeply (70°) to the SE. The quartz vein/lode averages 2.7m width and has significant strike and dip continuity (˜500m). The high-grade zones are generally wider and sulphide rich, with pyrrhotite and arsenopyrite being the dominant sulphide species. Mineralisation is related to a secondary phase of quartz veining with associated sulphide mineralisation.
