An evaporation plant was built in 1928. It used brine that was collected in a cavity in the MacKay seam, Brine Pond, No. 4 level and also brine was created on the surface by spraying the waste salt pile.
A high quality coarse salt for the fishery trade was made until 1947 when the process was discontinued.
