In the mezzanine gallery there are displays telling the story of Our Place, featuring objects and stories from the Goldfields from aboriginal history to the tales of early miners, the bringing of water and the development of the Superpit. Many early photographs in the displays are from the studio of pioneer Goldfields photographers JJ Dwyer and TF Mackay. The Museum’s underground Gold Vault features a spectacular collection of gold, jewelry and historical items. The Gold Vault also features the unique Geological Survey collection of nuggets, decorative miners’ brooches and the first gold bar refined in Kalgoorlie- Boulder.
