Assignment
Our client, a government mining agency, was interested in the exploration and exploitation
potential of a specific suite of minerals in ten countries of central and southern Africa.
The proposed project involved a general overview of the potential for these minerals in the
whole of Africa, subsequently focusing on the specified countries, and including a simplified
geological map showing mineral locations. This was followed by a second, more detailed study
of South Africa, Uganda and the Democratic Republic of the Congo (DRC), which had been
determined by our client as having the greatest potential for these minerals. Our client
was primarily interested in economically significant information for each prospect or deposit,
such as the nature of the mineralisation, estimated grade/reserves and the history of
exploitation. Local infrastructure and accessible references or reports on the occurrences
were also of great interest.
Approach
The first part of the study was based on desk research. Roskill’s own report on the
commodities and its in-house database formed the basis of the initial investigation but
the major part of the work depended on bibliographic searches at the extensive reference
collections of the Geological Society and the British Geological Survey. The follow-up
investigation involved primary research in the chosen countries and included meetings
with governmental organisations, national Geological Surveys and mining and exploration
companies, to discuss mineral occurrence and arrange further data collection. This was
supplemented by additional bibliographic work with the Museum of Central Africa (MRAC)
in Brussels.
Result
The client was supplied with interim and final reports giving a summary of the potential
for the specified minerals in central and southern Africa, and a detailed review of
specific occurrences in the three chosen countries. This included an extensive reference
list, coloured maps and up-to-date concession information. Since a significant proportion
of the work focused on prospective geologic settings, the reports also contained information
on other minerals that are commonly associated with those of prime interest.
