Afri-Can Marine: Feature 17; New Target Area and Diamond Potential is Validated by Recent Survey

MONTREAL, QUEBEC--(Marketwire - Nov. 20, 2007) - Afri-Can Marine Minerals Corporation ("Afri-Can")(TSX VENTURE:AFA)(FRANKFURT:AJF) is pleased to announce it has completed the third of four progress reports covering analysis and interpretation of the geophysical survey and vibracoring data gathered in November 2006 on the Block J marine diamond concession in Namibia. The report is entitled "The Geology of Feature 17 and Proposed Phase 3 Sampling Grid (Round 1)" and is available on our website at and on the SEDAR website at The geological history of Feature 17 has been established in considerable detail as a result of work done in 2006, supported by earlier work. Previous conclusions regarding the potential diamond content of Feature 17 and of Block J are supported and strengthened by the recent results.

A comprehensive NI 43-101 report, which is summarized at the end of this press release and was published in 2006 based on earlier Phase 1 and Phase 2 sampling, concluded that there is potential for up to 1,600,000 carats in a narrow strip extending north and south from Feature 8 to the lease boundaries. The new information from the modern geophysics and vibracores supports that conclusion. The identification of Basal Miocene and Terrestrial-Colluvial Formation material in Feature 17 (see Map 1) proves that the postulated target strip extends at least the 25 kilometres southwards from Feature 8 to the southern boundary of Block J.

The Valley Fill sediments occupying the small drainage valleys in Feature 17 (see Image 1) have become a potential target because their age has been determined, and they are now known to post-date the arrival of diamonds at the west coast of southern Africa. Phase 1 sampling in Feature 17 recovered three diamonds from sediments that were probably derived from the Valley Fill formations. It is proposed to test the Valley Fill sediments as part of the Phase 3 round 1 sampling. The primary sampling target identified in Feature 17 is about 1.2 km2.

- The sediments contain gravels with some exotic pebbles that might be diamondiferous and therefore are areas that should be tested by sampling.

- A programme, comprising 82 samples for the first round, has been designed to evaluate the known deposits and to test the potentially diamondiferous areas. A second round of sampling will follow-up on the results of the first round

- The equipment that will be used for the forthcoming sampling programme will be more powerful than that previously used, will be able to sample harder formations, and will take larger samples. Phase 3 quantitative large-bore sampling will establish Inferred Diamond Resources in Feature 17 in compliance with National Instrument 43-101.

"We are pleased with the progress of the work and look forward to the successful completion of the resource delineation program," commented President and CEO of Afri-Can. "Feature 17 hosts many distinctive geological features and the most recent interpretation of data considerably improves our understanding of the area and confirms its significant diamond potential."

It is proposed that a first round of Phase 3 sampling, concentrating on the primary target area (see Map 17), with lines of samples 200 metres apart and samples at 100 metre intervals with approximately 82 samples of 10 square metres each, will cover the target area with the objective of establishing an Inferred Diamond Resource in compliance with NI 43-101. This program, which is scheduled to begin as soon as the conversion and commissioning of the vessel "DP Sampler" has been completed, is anticipated to take about 14 days to complete.

The potential diamond content described above is estimated in the technical report entitled: "Phase 2 Sampling in Feature 8, EPL 2499, Offshore, Republic of Namibia" (see or, as reported in Afri-Can's press release of January 31st, 2007. The report, which complies with NI 43-101, concludes that:

- Feature 8 contains mineralized valley lag-gravels adjacent to the outcrop of the basal Tertiary sediments. The report interprets that the outcrop of the diamondiferous basal Tertiary sediments, and their associated lag gravel deposits, extends the whole north-south length of the property, but they have not been adequately sampled. In this case, assuming a deposit width for the lag gravels of 250 metres, the potential deposit area is about 11.5 square kilometres on Block J. Applying the average recovered grade of all the samples (0.053 carats per sq. m.) in this geological environment suggests a total potential diamond content of about 600,000 carats.

- However, it has been shown historically that the device used for the Phase 1 sampling has regularly understated the grades and diamond content of deposits. In addition, it is documented that the device used for the Phase 2 program was unable to penetrate and adequately sample the diamondiferous sediments lying deeper in the geological column. Therefore it is expected that modern, more accurate sampling technology will reveal higher grades than those recorded in the Phase 1 and Phase 2 sampling. To simulate this, applying the average recovered grade of the best 20% of the samples (0.146 carats per sq. m.) suggests a potential diamond content of 1,600,000 carats. These figures only apply to the lag-gravels adjacent to the outcrop of the basal Tertiary sediments. There is further potential on Block J in the other geological environments described in the report. (As a result of the detailed geophysics and vibracoring work done in 2006, the former lag-gravels are now identified as the Terrestrial-Colluvial Formation).

Statements of potential quantity are conceptual in nature. There has been insufficient exploration to define a mineral resource and it is uncertain if further exploration will result in the target being delineated as a mineral resource.
