With explosions and massive machines scraping into the earth’s crust like a bad case of scabies, its small wonder open cast mining has made what many see as an unpleasant impact on the planet’s surface. The face of the earth is beleaguered with giant scars, scoured out in our ongoing bid to the plunder the planet of its natural resources.
Chuquicamata in Chile is a colossus of a mine that has churned up a record total of 29 million tonnes of copper. Despite almost 100 years of intensive exploitation, it remains among the largest known copper resources, and its open pit is one of the biggest at a whopping great 4.3 km long, 3 km wide and over 850 m deep.
Copper has been mined for centuries at Chuquicamata, as shown by the 1898 discovery of a mummy dated around 550 AD found trapped in an ancient mine shaft by a cave-in. A great influx of miners was sucked in by ‘Red Gold Fever’ after the War of the Pacific, when at one stage the area was covered with unruly mining camps where alcohol, gambling, prostitution and even murder were common.
