Quartz crushing and processing equipment involved much more than just the actual stamper unit. They also needed boilers to drive them, buildings to house them and associated equipment for preparing the mercury to coat the plates and then processing the resulting gold laden amalgam.
Such infrastructure was beyond the means of the small claim holders and they hence had to carry their ore off to be processed. This could easily involve some distance and as a result you were very selective about just what ore got sent away for processing.
The good news for the Emu Creek field by mid winter was hence that “several owners of crushing machinery in the Western District have visited the goldfield and closely inspected the reefs. They pronounce them highly satisfactory, and that Emu Creek, as a reef mining district, has never been equalled in the colony. Arrangements have, I am informed, been made by them to remove suitable machinery at once to the field.”
