August 2, 2022, Toronto, Ontario – Toubani Resources, Inc. (formerly African Gold Group, Inc.) (TSX-V: TRE, FRA: 3A61) (“Toubani Resources” or the “Company”) is pleased to provide an update on the auger drilling campaign on the Kobada Est permit area of its Kobada Gold Project located in southwestern Mali, Africa. The update is based on the auger drilling completed to date, which commenced on April 7, 2022 and is still ongoing. Additional exploration activities are also planned for the Faraba permit area once this initial auger drilling at Kobada Est has been completed.

Toubani Resource’s President and CEO, Mr. Danny Callow, stated:
“Our auger drilling campaign is the next step of regional exploration to meet conditions on our two exploration permits (Kobada Est and Faraba). The wide spaced drilling programme was designed to identify trends above the background gold grade which then warrants further follow up with targeted drilling. We are very pleased with the results from the initial drilling, particularly in Target E where substantial high-grade intersections occurred. We have targeted additional drilling along strike in this area. These results are extremely encouraging and show the future upside exploration potential of our sizeable land package. It should be noted that this drilling is in an area previously untested, and therefore identifies further upside from what has been reported before. Our success with the drill bit, that has seen a 40% increase in overall resource, and а 140% increase in reserves shows that the Kobada and adjacent concessions are highly prospective and require further exploration to further increase resources and ultimately reserves.”
2022 Kobada Est Auger Drilling Campaign
The 2022 Kobada Est auger drilling campaign commenced on April 7, 2022 with a local Malian drilling company (Kounfaga Mining Services SARL) and has completed 6,878 m of drilling to date. The auger holes were laid out on fences either 200 m apart or 400 m apart with the holes being spaced 50 m along the fence lines. All 345 holes were drilled vertically to a depth of 20 m. The auger drillholes, with a 4.4-inch spiral, were sampled in 2 m increments resulting in 3,439 samples being sent to the Bamako SGS Laboratory. Drilling is continuing to test areas of interest.
The focus of the auger drilling campaign was on previously identified target areas, based on the termite soil geochemical sampling and geophysical interpretations, in the larger Kobada Est permit. The aim was to delineate shallow anomalous geochemical areas (testing the top 20 m) and potentially identify mineralised areas and evidence of structures. This would assist in determining the potential of mineralisation on the Kobada Est permit along the Kobada Shear and assist in the sighting of the follow-on AC or RC drilling campaigns.
Figure 1 shows the auger drilling programme, testing ten target areas, along the Kobada Est Shear (Targets A, B, C, D, E and F) and additional areas of interest (Targets L, Q, H, and M) with the geophysical interpretation as background.

Auger Drillhole Results
Targets A to F were testing the Kobada Est Shear for mineralisation while targets M, H, Q and L were testing soil geochemical anomalies and possible side shears. The strongest results are associated with the central portion of the shear with the southern and northern extents indicating auger geochemical anomalies above 40 ppb (green shaded polygons) with evidence of vein quartz (orange shaded polygons) being identified in the samples. This can be seen in Figures 2 and 3 which have the TMI aeromagnetics as background. The 40 ppb background grade is based on the histogram of 2,722 samples which indicates that the lower background grade is at 40 ppb.

Figure 3: Auger Drilling Results over the Northern Portion of the Kobada Est Shear (Target F).
Target E, the central portion of the Kobada Est Shear, is showing the best potential for elevated mineralisation with Target Q also returning some promising results.
Figure 4 shows the auger drilling collars for Target E with the 40 ppb geochemical anomalies, vein quartz presence, and gold intersections. The 40 ppb anomaly is approximately 1,200 m by 500 m as a surface expression with a higher grade 0.5 g/t anomaly with an approximate strike of 720 m. Target E could still extend further north and also seems to widen based on the 40 ppb anomaly and the presence of vein quartz. This is evident in Figure 5.

Figure 6 is an oblique view of the strip logs in Leapfrog software for Target E auger holes showing the elevated mineralisation above 40 ppb as disks. There is a possibility that the mineralisation is dipping to the west, but this still needs to be confirmed as the geology is still not understood. TRE geologists will be doing follow up surface geology work to assist in the geological interpretations.

The significant gold intersections above 0.3 g/t are shown in Table 1. These intersections occur in four of the Target areas (Target B, E, M and L). Target E has three auger drillholes that have elevated gold grades over 8 m in two of the holes.
The 0.3 g/t grade is based on the mineralisation halos that are used to constrain the main Kobada estimation and used to delineate the geological model.

Quality Assurance / Quality Control
The auger drillhole collars were sighted using a Garmin handheld GPS. The auger drilling was sampled every metre and then 2 m composites were created, and riffle split for assay samples. All samples were analysed at SGS (Bamako) Laboratory, which is a SANAS (South African National Accreditation System) accredited laboratory (facility accreditation number T0762). 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 20th sample (i.e., a rate of approximately 5% of submitted samples). The gold analyses were by fire-assay on 50 grams aliquot with AAS finish. The QAQC samples were monitored per batch and all QAQC samples have passed. Of the 3,439 auger samples, QAQC samples used during sampling comprised 60 standards/certified reference material made up of low grade AMIS0571 (0.59 g/t) and AMIS0569 (0.27 g/t), medium grade AMIS0441 (2.44 g/t) and high-grade AMIS 0559 (12.01 g/t). 78 Blank AMIS0681 samples and 59 field duplicates were inserted into the sample batches.
Future Exploration Work
The initial auger drilling results have identified Target E as the highest priority area for additional drilling to test these anomalies further. Additional auger drilling is currently underway to test the possible northern extension of Target E. Follow up AC or RC drilling will be required in future to test the possible lateral and strike extensions to get a better understanding of the geology in this area. In addition to Target E, Targets Q and L results suggest additional follow up work required.
