Operators are workers who operate the ore cleaning machine in the blast mine. Players should deposit blasted ore in the ore sacks near the blonde-haired operators, while collecting the cleaned ores from the brown-haired operator.
Speaking to an operator will result in dialogue on how to create dynamite.
If asked about the machine, they will state that it is used to quickly clean the blasted ores, and that the design is a secret, with those who try to copy it would "never get it quite right. I bet their machine would break down all the time." This is a reference to the fact that the struts on Prospector Percy's water wheel in the Motherlode Mine often break, while the blast mine's machine never breaks.
