Sample collection from the Nkamouna Deposit in Cameroon | CoG3 Consortium

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.

Annual Science Advisory Board meeting | CoG3 Consortium

Dr Paul Schofield gives an account of the CoG3 project’s annual Science Advisory Board meeting, held on the 6 and 7 June 2016 at the Bangor Acidophile Research Team (BART) centre, Bangor University.

The overall purpose of our Science Advisory Board is to assess and advise upon the strategic direction of the team’s project, CoG3: Geology, Geochemistry and Geomicrobiology of Cobalt. It also ensures that all components of the project stay focused on their objectives and remain sufficiently integrated so that the entire project can deliver the desired impact.

Fieldwork in Brazil | CoG3 Consortium

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.

Our project, CoG3: Geology, Geochemistry and Geomicrobiology of cobalt, aims to increase the security of the cobalt supply chain by:

  • identifying new, currently unused cobalt resources
  • developing new biotechnologies for effective extraction and processing of cobalt

One resource with the potential for bioprocessing is limonitic laterite deposits, one of which is the Piauí nickel-cobalt laterite deposit in Brazil. Continue reading

A visit to the UK’s synchrotron facility | CoG3 Consortium

Researcher Dr Agnieszka Dybowska describes a recent visit to Diamond Light Source, the UK’s national synchrotron science facility, during which the CoG3 team completed their first detailed spectroscopic analysis of laterite samples.

On Thursday 28 April we headed to Diamond Light Source in Oxfordshire, hoping to carry out atomic scale analysis of a sample from the Shevchenko laterite deposit in Kazakhstan – one of the samples we’re investigating as a potential new source of cobalt.

For some of us this was the first visit to a synchrotron facility, and definitely a great experience!
