Ceibo has put together a consortium of financial investors and mining companies to collaborate on and support the commercialization of its copper extraction technology.

The drilling was conducted in partnership with Columbia University under a program funded by the Department of Energy’s Advanced Research Projects Agency-Energy Mining Innovations.

The world's largest copper producer has named Ruben Alvarado as the company's new chief executive.

After buying Australia’s OZ Minerals, BHP is challenging for the mantle at a time when hitherto leader Codelco has seen output slide.

Copper headed for a third straight weekly loss, as concerns about China’s economy and widening housing crisis put markets in bearish mood.

The miner will also use "alternative actions" to extract materials from El Teniente following delays to expand it.

Chinese copper stocks readily available in the spot market totalled 82,600 tonnes on Aug. 14, up 17.5% year-on-year.

Cost overruns on projects to upgrade five mines could mean its debt is likely to reach $30 billion by 2030 from $18 billion now.
