African Gold Group Delivers a 44% Increase in Measured and Indicated Mineral Resource for the Kobada Gold Project to 1.71 Million Ounces

 

“We are delighted to announce these phenomenal results from our Kobada Gold Project in Mali. With the inclusion of significant exploration drilling within our oxides and fresh rock, we have achieved a substantial increase in total resource to more than 3.1 million ounces, which includes a 44% increase in Measured and Indicated resource of 1.71 million ounces, and a 26% increase in Inferred resource of 1.43 million ounces,” commented Danny Callow, CEO of African Gold Group

Highlights:

• A 44% increase in the Measured and Indicated Mineral Resource to 1.71 million Au ounces.
• A 26% increase in the Inferred Mineral Resource to 1.43 million Au ounces.
• Significant additional upside in the Inferred Mineral Resource.
• Gosso target drilling confirmed that the mineralisation and grades are higher than that observed at the Kobada main shear with an average grade of 1.11 g/t.
• Confidence in the geological model continues to increase with every exploration campaign and holes drilled over the Kobada Gold Project.
• Recent metallurgical test work completed as part of the feasibility study has revealed the sulphides are free milling and treatable through the same process circuit.
• Revised Kobada definitive feasibility study expected by the end of September 2021.
  

TORONTO, Sept. 02, 2021 (GLOBE NEWSWIRE) -- 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.
