Gold mines are dusty dirty places; full of mud, seeping water and grime. It’s a different place if that mine is turned into a world-class underground science lab.

The walls here are vacuumed regularly and even grated stairs are meticulously scrubbed with alcohol wipes by hand. Here we’ll introduce you to the woman whose job it is to keep the lab clean and the experiments dust free.
