Ancient mining techniques go well back into our history – well back into ourprehistory, in fact. As we progressed through the Stone Age, with more and more sophisticated tools and weapons being designed and developed, so too,our need for more and better raw materials for these implements. Stone and flint led to copper, then bronze, gold, silver, iron… all in the name of progress, war, technology, vanity or greed. In fact, it’s ironic (pun intended) that the substance prized and even mined by our ancient ancestors for some of the earliest stone tools and weapons – flint – was later a hindrance encountered by Classical miners – who were in many cases also Classical minors – in gold mining galleries described by Pliny the Elder in the 1st century AD as “thought to be the hardest thing that exists, except greed for gold, which is the most stubborn of all things.
