FOREIGN MEDIA: CHUQUI GOES UNDERGROUND!

 International media has come to its attention that after nearly a century of open-cut production, Chuquicamata in Chile is starting underground operations. 

 "From above, it looks like a colossal amphitheater carved from rock, or the vast crater from a meteorite that crashed into Chile´s Atacama desert ages ago"say The San Francisco Chronicle, but “after a century of exploitation, Chuquicamata has become too big, too deep and too old to continue digging in the open-pit method (…) So state-owned mining company Codelco is trying to head off closure by taking the daring step of converting (it) into the world´s largest underground mine”. 

In fact, Codelco has already invested USD$3.8 billion in the underground mining project in Chuquicamata, in order to extend the mine´s life for at least 50 more years, after decades in service of the country and its prosperity.   

Mining.com mentioned that Chuquicamata produced 443,000 tons of copper last year, but experts say that by 2019 it will be unprofitable, so a solution like this is pretty much needed. "Existing reserves are equal to 60% of all copper retrieved throughout the mine´s history, and Codelco believes the mine can still maintain an output of around 308,000 tonnes of copper per annum", they say.  

The online website also notes that "everything about Chuquicamata, affectionately known as "Chuqui" by Chileans, is epic in scale, and its history is in many ways the history of Chile".  

Those worldwide famous Chuquicamata pictures with huge open-pit areas are about to have a little twist once the underground project is finished. "It´s nostalgic but we feel we´re making history," said Mauricio Vivero, a construction engineer, to The San Francisco Chronicle. 

Codelco started the construction of these tunnels in july, and the copper and molybdenum extraction will last for about 42 years.  Since the extraction method will be totally different to the one existing today, the structural project will improve Calama’s life quality, because it will decreased to 97 percent the emission of dust and an pollution generated from mining activities.
