By 1892 there were six cyanide plants on the Ohinemuri Goldfield, plus others at Thames and Coromandel. The process was a great success, as the recovery of gold improved from 40-50% to 85-95%. During this time tailings containing cyanide were deposited directly into the Ohinemuri River from various mining operations.read more
