Archaeologists from the University of Chile have discovered a 12,000-year-old iron oxide mine in the north of the country.
Researchers say it is the oldest mine discovered in all the Americas.
Chief researcher Diego Salazar said the iron oxide was used by Huentelauquen Indians as a pigment in dying cloth and in religious rituals, revealing an unexpected sophistication in what was previously considered a primitive group of people.
"The fact they developed a mine shows the importance religion had in their lives, because iron oxide was not used as food, was not bought or sold," he said.
The ancient mine was discovered near the town of Taltal, in the Antofagasta region, 1,100 kilometres north of Santiago, in October 2008, but its antiquity was not determined until tests were conducted this year in US and Polish laboratories.

Named San Ramon 15, the mine was exploited heavily between around 10,000 BC and 2,000 BC.
It yielded over the millennia a total of 2,000 tons of pigment extracted from 700 cubic metres of rock.
Researchers also found a treasure trove of stone and conch mining tools in the area.
"We've found more than 1,000 hammers ... but considering the amount of material we have yet to sift through, the real number could rise to several thousands," archaeologist Hernan Salinas said.
Before this find, the oldest mine in the Americas was 2,500 years old and located in the United States.
