AFRICAN GOLD GROUP, INC: 48 METRES OF 2.95 G/T AU INCLUDING 19.20 METRES OF 5.91 G/T AU CONFIRMS GOLD DISCOVERY AT KOBADA, MALI
African Gold Group, Inc. (AGG) is providing results from the initial six holes drilled on the Kobada gold project in Mali, West Africa. Importantly, this drill campaign has extended the gold mineralization through the 125-metre saprolite horizon into bedrock.
The 41-square-kilometre Kobada concession is located in the Kangaba region of Mali. It hosts a significant anomaly that is defined by 12 kilometres of strike length with a corresponding width of one kilometre. This anomaly has greater than a 500-part-per-million, arsenic-in-soil geochemistry with coincident extensive artisanal surface, hardrock and placer mining activity. Previous work on the concession, commencing in the 1980s, was undertaken by French exploration entities: BRGM, La Source and Cominor (Cogema). Their collective work comprised surface geochemical and geophysical surveys, 1,736 metres of air core drilling, 13,200 metres of reverse circulation (RC) drilling, and 913.4 metres of diamond drilling. Their initial primary target within the 12-kilometre strike length that comprises the Kobada trend has been a one-kilometre zone of extensive artisanal hardrock mining activity referred to as zone 1.
Program objectives
AGG's initial exploration program at Kobada had two distinct objectives:
1. to verify and confirm the historical exploration work undertaken by Cominor. This verification was conducted in two ways; and
* three RC holes previously drilled by Cominor were twinned with AGG diamond drill holes to test the nature of the mineralization. Cominor holes, KBRC-56 and KBRC-127 located on Section 2200S, and KBRC-126 located on Section 2300S, were selected to be twinned for both the length and grade of their respective intercepts; and
* resample and analyze for gold, the rejects from two RC drill holes completed by Cominor (KBRC-126 and KBRC-127);
2. the second objective of AGG's diamond drilling program was to test the mineralization to depth and to obtain samples of previously untested bedrock mineralization below the saprolite horizon (holes KB05-3 and KB05-5). In addition, hole KB05-6 was drilled oblique to the section in anticipation of the existence of newly interpreted mineralized cross structures.
Results and analysis
Results from AGG's six diamond drill hole campaign, totalling 1,033 metres, are shown in Table 1 below. All samples from AGG's diamond drill program were analyzed by Eco-Tech Laboratory of Kamloops, Canada. Samples returning greater than 300 parts per billion gold (Au) were fire assayed.

Due to the possible coarseness of gold in drill core, metallic fire assay was undertaken on selected samples. The selected samples that were tested in this manner demonstrated an increase in gold values. As a result of the increase in gold values from these selected samples, AGG has requested all samples returning greater than one g/t Au that have not yet been subjected to metallic fire assay be tested using this process. These results will be disseminated in a subsequent release due to the time required to complete the tests, if material.
Results from historical RC drilling by Cominor along sections 2200S and 2300S are shown in Table 2 below. The samples from Cominor's RC drilling program were analyzed by AbilabAfrique de l'Ouest SARL located in Bamako, Mali.

"The results illustrated in both tables 1 and 2 provide AGG with the confidence to move aggressively with the development of the Kobada gold project not only along the initially targeted one-kilometre strike length within zone 1 of the concession but also along the entire 12-kilometre strike length that comprises the Kobada trend. AGG has successfully demonstrated oxide gold mineralization to a depth of approximately 125 vertical metres in saprolite and, furthermore, have extended the gold mineralization an additional 25 metres into bedrock. The bedrock mineralization is characterized by intense veining/silification and disseminated arsenopyrite in intercalated argillites and greywackes, and remains open to depth. As previously stated, the thickness of the saprolite horizon bodes well for demonstrating the potential for a low-cost surface deposit that will ideally complement the deeper resource potential. The occurrence of very high grades of gold along with the presence of free gold strengthens the economic potential of this mineralization. Results to date emanate from within approximately 200 metres of the one-kilometre primary target (zone 1) and indicates a broad zone averaging 30 metres in width with an associated grade averaging between one and three grams per tonne. Furthermore, we are encouraged by the identification of mineralized cross structures intersected in KB05-6, which further adds to the broader potential of this new gold trend," states Greg Hawkins, PGeo, technical director at AGG.
As per AGG's technical objective as stated in 1(a) above, a comparison of results derived from twinning three of Cominor's original RC drill holes with AGG diamond drill holes to confirm the presence of gold mineralization is shown in Table 3 below.

"The diamond drill twinning campaign has enabled AGG to gain a greater degree of geological information than was generated through previous RC drilling. As illustrated in Table 3 above, results from twinning holes can vary. The comparison of results from different drilling techniques can be problematic in areas where there is groundwater inflow in the case of RC drilling and variable core recovery in the case of diamond drilling. Both of these conditions were encountered in the upper levels of zone 1," states Mr. Hawkins, PGeo, technical director at AGG.
As per AGG's technical objective as stated in 1(b) above, results derived from AGG's resampling of two of Cominor's RC drill holes are shown in Table 4 below. These Cominor RC drill pulp rejects were resampled and collected by AGG's technical personnel, and reassayed by AbilabAfrique de l'Ouest SARL.

"Zone 1 appears to be characterized by significant, coarse free gold which typically leads to a degree of variability in results when resampling drill pulps (as illustrated in Table 4 above)," added Mr. Hawkins.
Ben Adoo, chairman of AGG, states: "We are extremely encouraged by the overall results of the initial program which confirms the potential for a significant gold discovery within zone 1 of the Kobada project. Furthermore, we believe that the 12-kilometre Kobada trend may represent a major new gold-bearing structure in Mali, West Africa."
The drilling program is under the supervision of Chrisropher Naas, PGeo of CME & Co., a qualified person under National Instrument 43-101. This press release has been reviewed and approved by Mr. Naas.
