African Gold Group, Inc. (TSX-V: AGG, OTC: AGGFF, FRA: 3A61)
(“
AGG” or the “
Company”) is
pleased to announce an updated Mineral Resource Estimate
(“
MRE”) for its Kobada Gold Project (the
“
Project” or “
Kobada”) located in
southwestern Mali, Africa. The MRE update is based on additional
drilling completed on the Kobada main shear from September 2020
until January 2021, which will form part of a revised definitive
feasibility study (expected to be delivered by the end of
September) (the “
2021 DFS”). Additionally, the
Company has engaged various advisors to outline potential corporate
opportunities.
The drilling campaign was focused on the “gap”
area and the northern portion of the Kobada main shear, as well as
testing the Gosso target for future potential. The drilling has
once again increased the confidence in the geological model even
further and resulted in a substantial increase in the Mineral
Resource Estimate.
Danny Callow, CEO of African Gold Group,
commented: “With very little additional drilling on the
Phase 4A drill programme, we have proven the continued significant
upside in our Kobada asset. These results are substantially better
than those in the July 2020 Definitive Feasibility Study, and we
are very excited to see this continued growth in measured and
indicated resources. From this new drilling, we have added
additional shallow, easily accessible inferred resources, and
through further targeted drilling programmes, in Phase 4B and 4C we
believe there is substantial further upside in resource growth.
We have always stated that there is significant
upside in Kobada, and with more than 50 km of shear zones still
untested with the drill bit, we believe we are sitting on a
substantial world class resource.”
2020 Drilling Campaign
The 2020 drilling campaign, running from
September 2020 until January 2021, consisted of 43 drillholes
totaling 6,364 m. Of these, four drillholes (522 m) were drilled at
the Gosso target and the remaining 39 drillholes (5,842 m) were
drilled in the “gap” area and northern extents of the northern
domain of the Kobada main shear. The Gosso drillholes were all
completed using diamond drilling while the Kobada drilling was a
combination of diamond drilling (8 holes @ 1,258 m) and RC drilling
(21 holes @ 2,890 m) with selected RC drillholes being completed
with diamond tail (10 holes @ 1,221m RC and 473 m diamond) to drill
into the sulphides.
The main focus of the 2020 drilling campaign was
to confirm the geological model and improve the confidence in the
model even more to enable additional Mineral Resource conversion of
the oxides to the measured and indicated resource categories. The
drilling was also used to test and confirm the depth extension of
the lateritic (soft) material, the transition zone and the
sulphides at depth.
For the Kobada main shear drilling, 34
drillholes intersected the mineralised zones and had an average
accumulated mineralisation width of 29m @ 1.22 g/t. This drilling
has significantly contributed to the increase in the indicated
resource in the northern domain of the Kobada main shear. The
drilling also highlighted areas of deeper weathering with oxide
material extending further down to a depth of approximately 160 m
in places, approximately 60 to 80 m deeper than originally
anticipated.
The Gosso drillholes confirmed the
mineralisation observed in the historical drillholes with the four
drillholes having an average accumulated mineralisation width of 12
m @ 1.11 g/t.

Mineral Resource
The geological model was revised with the
additional 2020 drilling campaign information. The biggest impact
was in the inferred category of the wireframes, the deepening of
the oxide and sulphide transition depth, and not modelling the
weathering zones as individual subdomains. The model is divided
into five structural and grade-constrained domains which are
further split into weathering zones of laterite, saprolite,
transition and sulphide. The 2020 Definitive Feasibility Study used
a sub-domaining for the weathering profile. However, this was
reinvestigated and the mean gold grades per weathering profile show
a natural decrease with depth and the log probability plots of the
total composites show a good correlation and do not indicate that
the orebody should be split into sub domains for estimation
purposes. Drillholes were composited to a 1 m length to standardise
the sample support size. A capping analysis of the 1 m composited
data was conducted per domain to identify any outliers in that
dataset. The outlier grade results were capped per domain and the
capping represents the 99th or 98th percentile. The search ellipse
for the domains were set from the strike and dip directions
obtained from the orebody wireframe generation and variograms were
generated for all domains. The block model was based on the kriging
neighbourhood analysis (KNA) and had a parent estimation cell of 5
m x 10 m x 10 m in the x, y, and z. Grade estimation was conducted
using Ordinary Kriging (“OK”) based on the variograms and the
estimation was done per structural domain.
Geological losses of 5% for measured, 10% for
indicated and 15% for inferred have been applied to the Mineral
Resource. Only resources falling within a resource open pit shell
based on a gold price of USD 1,800 / oz have been declared.

Table 2: Kobada Mineral Resources per Weathering
Zone as of 1 July 2021
The increase in the Mineral Resource from 2020
to 2021 is primarily due to the improved gold price which improved
the reasonable prospects of eventual economic extraction by
allowing for a larger and deeper resource pit to include more
sulphides, the additional drilling information which improved
geological confidence and assisted in converting Inferred Mineral
Resource to Indicated Mineral Resource.

Quality Assurance / Quality
Control
The 2020 drilling campaign was undertaken by
AMCO and supervised by Minxcon (Pty) Limited of South Africa. The
drilling was a combination of diamond drilling (NQ) as well as RC
drilling. Diamond drilling core was split and either sampled in one
metre intervals or along lithological or structural contacts. The
RC drilling was sampled in one metre increments and riffle split
for assay samples. All samples were analysed at SGS (Bamako)
Laboratory, a certified commercial laboratory. A strict QA/QC
program was applied to all samples; which include insertion of
either certified reference material (CRM’s), a blank sample or
duplicate every 10th sample (i.e. a rate of 10% of submitted
samples). The gold analyses were by fire-assay on 50 grams aliquot
with AAS finish.
Upside Potential
Upside potential remains at the Kobada main
shear to upgrade some additional inferred mineral resources to
indicated. In addition to this, the Kobada Project has significant
upside potential in the 55 km strike of potential mineralised shear
zones. Of these, the Gosso Target is the more advanced with limited
drilling completed (21 drillholes) with mineralisation in 16 of
these drillholes with the latest 2020 drilling confirming
mineralisation at this target. Initial field investigations by the
AGG geologists, in early 2021, has highlighted the potential at the
Kobada Est targets where artisanal mining has exposed mineralised
structural features.
