African Gold Group, Inc. (TSX VENTURE:AGG) has reported the analytical results for 17 near surface, step-out reverse circulation drill holes from the Company's Kobada, Mali gold project.
The 17 RC drill holes that are the subject of this release are collared in a newly-discovered, distinct structural setting, the "Foroko North Zone" or "Foroko North", that lies up to 4.3 km north-east of the most northerly section of the Kobada, Zone 1 gold deposit. This structure emanates from AGG's Foroko concession, which is contiguous with AGG's Kobada concession, on Kobada's eastern boundary, and projects north into the northeastern section of the Kobada concession. The Foroko North structure is oriented in a North/South (N-S) direction as distinct from the Kobada structure, which is oriented at North 20 degrees East.
The Foroko North structure is marked by a 2 km long N-S zone of contiguous ancient orpaillage workings which have resulted in collapse zones in the duricrust averaging 50 meters in width with areas up to 100 meters wide. The investigation of certain of the workings, that have not collapsed, reveals that the artisanal mining was to depths of approximately 6 meters and mining was exclusively within the mottle zone (saprolite devoid of structure) of the laterite weathering profile. To the north of this zone there is an additional 3 km of sporadic NNE oriented ancient and modern orpaillage activity that extends onto the Chakabougou airborne geophysical anomaly that is located in the northern region of AGG's Acoma license. (see AGG press release - Aug. 10, 2010).
The 17 holes reported in this press release are located within the northern most quarter of the Foroko North structural anomaly. KBRC10-32, the most northern hole, lies approximately 600 meters from KBRC10-48, the most southern hole.
"Employing the model that evolved from the Kobada Zone 1 efforts and also based on limited evidence derived from the Foroko North workings, south directed holes were drilled targeting east-west (E-W) striking tension gashes within the N-S striking Foroko shear zone. The success of this program has proven this model to be correct and accordingly we would anticipate that we may well intersect E-W mineralized tension gashes along the entire 2 km strike length of the Foroko North shear." States Dr. Kevin N. Downing, Sr. Structural Geologist.
"We wish to reiteriate that AGG's Kobada, Mali gold project represents a 216 sq km footprint contained within 4 contiguous concessions. As of this date, less than 10% of this footprint has been explored. We most recently reported on the results of our airborne survey that was flown over the entire Kobada footprint and that this exercise generated seven (7) structural targets. All seven (7) of the newly identified Target Areas exhibit geophysical characteristics that are similar to the mineralized structures contained within the Zone 1 deposit. All of the Target Areas are traversed by the favorable NNE and NE-SW mineralized faults. Six (6) of the Target Areas have coincident radiometric potassium anomalies interpreted as granitoid intrusions with hydrothermal alteration. All of the Target Areas have shown evidence of historical and/or current artisanal mining. The discovery of this new gold zone at Foroko North speaks directly to AGG's growing potential to significantly increase Kobada's gold resources. We have no doubt whatsoever that additional discoveries of new gold zones remain a matter of time and methodical exploration, they are there and we intend to discover them," states AGG President, Michael A. Nikiforuk.

Sampling - QA/QC Program
RC cuttings are recovered at the bottom outlet of the RC rig cyclone into 50-kg capacity poly-weave bags to recover the cuttings from each 1 meter of drill penetration. Each one meter sample weighs an average of approximately 19 to 23 kg. Each sample is passed through a 3-tier Jones Riffler (1 to 8 split), the samples are riffled twice to obtain from 3 to 5 kg of cuttings which are put in a numbered sample bag. Each bag is sealed and picked up on site by ALS Chemex Laboratories for delivery to its Burkina Faso facilities. The remaining 14 to 18 kg of cuttings (field rejects) are stored in camp under tarps to protect the bags against the elements.
Original samples are analyzed using Leachwell on 2 kg of pulp. Leachwell is a bottle roll cyanidation procedure with the addition of a catalyst to speed up gold dissolution. A QA/QC program is in place and includes: blank (1 in 20 samples), duplicates (1 in 20), standards (1 in 20), external lab checks (1 in 30) and two different analytical procedures checks (1 in 100).
