Glencore’s Mutanda Mine in the Democratic Republic of Congo produced 23.9 kilotonnes of cobalt in 2017 making Mutanda the world’s biggest producer of the blue metal that is also owned by a publicly-traded company.
Ranking was compiled using data from Mining Intelligence. Annual cobalt production is gathered from publicly-traded mining companies, as well as some state-owned mines. Mining complexes are excluded. Stock exchanges used are TSX, TSX-V, ASX, LSE, LSE-AIM, NYSE and JSE.
China Molybdenum’s Tenke Fungurume came in second and with an asterisk, since cobalt production is based on 2016 numbers when the mine was run by Freeport McMoran, which released the mine’s last production results in its annual report. The Arizona-based copper giant sold Tenke Fungurume in 2016 to China Molybdenum for $2.65 billion. China Molybdenum doesn’t publish cobalt production numbers.
Mutanda and Tenke Fungurume are the powerhouses of our cobalt listing, accounting for 60 per cent of the total annual cobalt production of the companies compiled. Both are copper-cobalt mines operating in the Democratic Republic of the Congo, source of most of the world’s cobalt. S&P Global estimates that global mined cobalt production was 115 kilotonnes in 2017, down slightly from 116 kilotonnes in 2016.
Cobalt has been on a tear. Metal Bulletin (paywall) says low grade free market cobalt hit a high of US$42 lb in the second quarter of 2018. Two years ago the metal could be had for less than US$12 lb.
Mutanda will not be the top cobalt mine for long. Glencore restarted its Katanga Mine, also located in the Democratic Republic of the Congo, at the end of 2017. Katanga is expected to produce 11 kilotonnes of cobalt in 2018 before tripling output in the following year to 34 kilotonnes.
Mutanda – Glencore’s Mutanda mine produced 23.9 kilotonnes of cobalt in 2017. The open-pit mine started production in 2011 and is locate in the Democratic Republic of Congo.
Tenke Fungurume* – China Molybdeum’s Tenke Fungurume produced 16.05 kilotonnes of cobalt in 2016, thus the astericks. Freeport McMoran sold Tenke to the Chinese company for xx in 2016.
