Afri-Can Minerals completes Namibian survey

Montreal-based Afri-Can Marine Minerals (AFA-M) has completed a marine geophysical survey of block J at its marine diamond concession north of Luderitz, Namibia.

Afri-Can says 17 prospective areas in eight geomorphical features may have potential for diamond entrapment.

Marine & Coastal Geosciences, Afri-Can’s South African-based contractor, completed 910 line km of high-resolution surveying on the block. It recommends a sampling program to determine and model the geology and test for the presence of diamonds at each site.

The identified features represent various depositional environments in water that is 75-110 metres deep.

Bathymetric, seismic and sonographic data have outlined:

• The Northern deposit — a fine, sedimentary deposit with four depressions draining into an embayment;
• The Northern reef — a large reef complex comprised entirely of crystalline bedrock outcrops with minimal coarse sediment cover;
• The Northern embayment — a large northwest-facing embayment measuring 3 km by 12 km in its central part;
• The Northern terrace — a gradually sloping terrace measuring 3.8 km by 13 km;
• The Central reef — a reef complex made up entirely of crystalline bedrock;
• The Southern deposit — a sedimentary deposit extending 21 km from the southern boundary of the concession;
• The Southern depression — a mostly fine sedimentary deposit; and
• The Southern reef — an occurrence of semi-isolated reefs consisting of outcrops of crystalline bedrock.

Afri-Can is planning a three-phase prospecting program, including initial sampling, follow-up sampling and mine evaluation sampling.

Planning for the initial sampling will take about two weeks. A contractor will be named soon thereafter.
