The gold was brought to the surface as small particles embedded in lumps of quartz. The quartz was then crushed into a fine dust by stamping batteries in a stamp mill. A stamp battery contained a row of stamps. On the bottom of each stamp was a heavy piece of iron steel. Each battery was driven by a cam shaft which was turned by a water wheel. The steel shoes went up and down between wooden guides and pounded the quartz which had been fed into steel boxes underneath the stampers. Ideally the stampin
