African Gold Group. (TSX-V: AGG) is pleased to provide diamond core drilling results from its Kobada gold project located in south eastern Mali, Africa. The five hole diamond drill program was designed to confirm and expand knowledge of existing shallow mineral resources, as well as explore down dip and along strike from known mineralization.
“Our follow up diamond core drilling program at Kobada, Mali has delivered further exciting results that continue to demonstrate shallow and wide zones of gold mineralization at the project that was demonstrated in both our recent 2018 RC drill hole results and from historical drilling,” noted Stephan Theron, President and CEO. “We now plan to undertake further drilling after the end of the wet season along with the results from our feasibility gap analyst study currently being undertaken by DRA.”
DD Drilling Results
500.4 metres in five (5) DD holes were completed in phase 1. Drilling focused on the northern limits of the historical and published NI 43-101 Mineral Resource in an area where previous drilling was orientated parallel to mineralization trend. (Figures 1, 2 and 3).

Geology of Kobada
Gold at the Kobada Project is present in the laterite, saprolite and quartz veins that comprise the Kobada Project. There are also placer style deposits in the region, although these have largely been exploited by artisanal miners. Gold mineralisation was coeval with the hydrothermal events that introduced the regionally common quartz veins. The 20°NE structures are the only regional structures that have been identified on the property, the E-W and low angle features seem to be confined to the mineralised zone in-between discrete shear zones.
Mineralisation at the Kobada Project extends for a minimum strike of 4 km and is associated with narrow, irregular, high-angle quartz veins and with disseminated sulphides in the wall rock and vein selvages. Mineralisation occurs as free gold, sulphides present include arsenopyrite, pyrite and rare chalcopyrite. Visible gold is not common. Arsenopyrite (up to 5 mm) is localised near vein selvages and as fine-grained disseminated patches within the host rock. Pyrite occurs in finely disseminated patches within the host rocks and as euhedral crystals in the black shale, generally as trace to 3% by volume with up to 10% locally in the wall rock over centimetre scale intervals adjacent to quartz veins.
Veins have a milky white colour, are generally discordant with a thickness ranging from millimetric to sub metric. Mineralised veins are narrow, high-angle quartz veins, either cross-cutting another vein or the main fabric.

Quality Assurance / Quality Control
Drilling was undertaken by Geodrill and supervised by Minxcon (Pty) Limited of South Africa.
During the drill program, one metre assay samples were taken from diamond drill core collected during drilling, split (core cut) and sent for assaying at SGS (Bamako) Laboratory, a certified commercial laboratory, and remainder has been retained for cross checks, and future reference. A strict QA/QC program is applied to all samples; which include insertion of one certified mineralized standard and one blank sample in each batch of 20 samples (at a rate of 5% of submitted samples). The gold analyses were by fire-assay on 30 grams of pulp.
