CoG3 project member and University of Manchester PhD student Sulaiman Mulroy reports back on a recent fieldwork trip to Cameroon in West Africa.
In June 2016 I travelled to Cameroon to collect samples from the Nkamouna laterite, one of a number of lateritic ore deposits formed on top of lenticular serpentinite rocks, which cover around 240km2 in the East of Cameroon.
In total the region hosts seven lateritic ore bodies, covering ~1250km2, though only two have been subjected to rigorous exploration: Nkamouna has proven and probable reserves of 54Mt at grades of 0.25% Co and 1.7% Ni, and further north, at Mada, 150Mt of inferred resources of similar grade are believed to be hosted in the laterite.
In April 2016 the CoG3 team travelled to Brazil to carry out fieldwork at the Piauí deposit. Researcher Dr Paul Schofield describes their trip:
Cobalt is a technology-enabling metal with numerous applications that are particularly essential to the ‘green agenda’. Despite cobalt being such a critical material, there is a very high risk associated with its supply.
