Open Days. In the last few years of the 20th century, the
DCC started to hold regular Open Days in the mines when people could turn up and
visit the mines to see the work the Club members were doing and to get a taste
of caving for themselves. Demonstrations include practical experiments in making and using stone tools
and in extracting copper metal from the ore. Note the gloves and safety
glasses to meet health and safety standards. The third child keeps well
out of the way behind a protective chair.
