One of the interesting aspects of this stage of the field’s development is that as small mining syndicates rather than companies were firmly in charge of the mining claims, no one had the scale of workings to justify actually establishing their own crushing operations (as had originally happened with the pioneer quartz reefing at Tambaroora in the early 1850s).
This meant that crushing mills were operated as independent businesses who had more interest in getting through lots of ore, than they had in actually recovering gold. Also when there was so much gold being recovered anyway, why worry about that extra half an ounce per ton?
This mitigated heavily against them investing in additional ore processing technology such as occurred at Clunes in Victoria. It also meant that the tailings of the stamp batteries became a gold rich resource which many alluvial miners would work over profitably in the decades following the boom.
