Toubani Successfully Extends Overall Kobada Mineralisation by 1 km
TORONTO, March 07, 2023 - Toubani Resources Inc. (ASX: TRE; TSX-V: TRE) ("Toubani Resources" or the "Company") is pleased to provide the first set of results from the ongoing drilling program at its Kobada Gold Project in southern Mali.
Highlights
- Drilling has extended mineralisation by almost 1km to the north and south of the Kobada Main Deposit
- Kobada Main Deposit currently hosts a Mineral Resource1 of 3.1 million ounces of gold over a strike length of 4.5km
- Mineralisation remains open north and south of the Kobada Main Deposit
- Excellent first results from the Kobada North 1 target area with 9m at 1.32g/t and 14m at 1.02g/t
- Further assay results at Kobada North 2 testing along an additional 1.7km of strike are pending
- Drilling continues on site with the focus now moving to step out holes at the Gosso target, where previous drilling has already intersected mineralisation
Chief Executive Officer, Phil Russo commented: "For the first drill holes of the program to extend mineralisation by 1 km, including 650 meters at Kobada North alone, is an exceptional result. These results demonstrate both the scale and the potential of the Kobada district and to be able to expand the footprint of mineralisation so quickly, while still open along strike, is a significant step forward in unlocking this project. We believe we have a very large system across an extensive and, remarkably, still underexplored belt. We now look forward to drilling at Gosso, which is currently underway and has returned excellent initial results in historical drilling."
Drilling Results and Commentary
Drilling was designed to test potential extensions to mineralisation at the Kobada Main Deposit (Figure 1). Extensive artisanal workings can be found along strike and along trend from Kobada Main, yet almost no drilling has been undertaken.

1 Combined Measured, Indicated and Inferred Mineral Resource of 103.57Mt at 0.94g/t.
Refer to the Company's prospectus dated 12 September 2022 and released on ASX on 25 November 2022
Figure 1: Plan showing location of Kobada North and Kobada South
At Kobada North 1, two fences of drilling were completed stepping out 400 metres and 650 metres, respectively, north of the last fence of drilling within the Kobada Main resource. The drilling tested below and adjacent to artisanal workings.
Results are shown on Figure 2 and 3 and detailed in Appendix 1 with key intersections including:
- 9m at 1.32g/t from 112 metres including 4m at 2.64g/t (KN1/22_P009)
- 14m at 1.02g/t from 81 metres including 1m at 2.28g/t and 1m at 3.75g/t (KN1/22_P008)
- 1m at 7.86g/t from 59 metres (KN1/22_P007)
With drilling successfully confirming the continuity of the mineralised system to the north, follow up drilling will now be planned to systematically test the tenor of mineralisation along the structure. This will then enable this area to be included in a forthcoming update to the Kobada Mineral Resource.

At Kobada South, three fences of drilling were completed. The most southerly of these stepped out 250 metres south from the last fence of drilling within the Kobada Main resource and successfully intersected mineralisation, including:
- 3m at 1.81g/t from 50m and 3m at 1.20g/t from 61m (KS22_P003).
Drilling was also carried out to infill a 500m gap in drilling at the southern end of the Mineral Resource with results to inform a resource update planned for later in 2023. Key results included:
- 1m at 8.35g/t from 68m (KS22_P012) and 3m at 1.8g/t from 82m (KS22_P014).
In addition, drilling was completed to test extensions to mineralisation on a parallel lode to the Kobada Main lode. Intersections of 2m at 0.75g/t from 6m and 4m at 0.52g/t from 40m (KS22_P025) were returned, demonstrating continuity of mineralisation on this eastern lode for a further 200m. Further work is planned in future programs to test the potential of this parallel lode.
All results are shown on Figure 4 and detailed in Appendix 1.

Forward Work Program
Following the drilling at Kobada North 1 the drilling rig has completed two further fences of drilling at Kobada North 2, which steps out a further 1.7 km along strike to the north to test for the presence of the mineralised system. The fences are sited based on interpretation of geophysical data and artisanal workings. Results are awaited with laboratory turn around times significantly improved in recent weeks.
The rig is currently drilling at the Gosso target, which is located on a parallel structure to the Kobada Main Deposit. Previous drilling at Gosso2 returned results including:
- 36m at 1.64 g/t from 72m (KBRC11-140)
- 3.1m at 4.25 g/t from 34.6m (G20_PH3A_20)
- 3m at 2.59 g/t from 30m (KBRC11-144)
- 5m at 1.90 g/t from 133m (KBRC11-142)

Appendix 2. The following tables are provided to ensure compliance with JORC Code requirements for the reporting of Exploration Results from the Kobada Project
Section 1 Sampling Techniques and Data
(Criteria in this section apply to all succeeding sections.)
Criteria | JORC Code explanation | Commentary |
Sampling techniques |
| Drilling samples collected using reverse circulation (RC) percussion drilling. The entire sample is collected , homogenised and split to achieve a sample of approximately 2kg which is submitted for analysis. Analysis is carried out in an independent commercial laboratory using fire assay. |
Drilling techniques |
| Reverse Circulation drilling using 127mm face sampling hammer |
Drill sample recovery |
| RC samples are weighed to quantify recovery Recovery is also noted in the sampling sheet. |
Logging |
| Geological logging of RC drilling is completed to an acceptable standard for use in Mineral Resource estimation. Logging is both qualitative (weathering, colour, lithology, alteration) and quantitative (% veining, sulphides) All drilling reported (100%) has been logged. |
Sub-sampling techniques and sample preparation |
| All RC samples are split using a riffle splitter with one split (approximately 1 to 2 kg) collected for laboratory testing and the remaining amount after splitting is retained in the bulk bag for future reference. All samples were sampled dry. Sample moisture is noted in the sampling sheet. Appropriate sampling procedures are used to ensure representivity. It is believed that the sample size is in line with standard practice and is appropriate to the grain size of the material being sampled. |
Quality of assay data and laboratory tests |
| Samples were submitted to the SANAS and ISO/IEC 17025 accredited SGS Laboratory in Bamako. Samples were tested by fire assay with an AAS finish. Samples < 3.0 kg were dried in trays, crushed to a nominal 2 mm using a jaw crusher, and then < 1.5 kg were split using a Jones-type riffle splitter. Reject sample was retained in the original bag and stored. The sample was pulverised in an LM2 pulveriser to a nominal 85 % passing 75 µm. An approximately 200 g subsample was taken for assay, with the pulverised residue retained in a plastic bag. All the preparation equipment was flushed with barren material prior to the commencement of the job. A 50 g subsample was fused with a litharge-based flux, cupelled, and the prill is dissolved in aqua regia, and gold is determined by flame AAS (Detection Limit 0.01 ppm). Every 10th sample is a CRM, blank or duplicate. It is believe that acceptable levels of accuracy and precision have been achieved based on the control samples. |
Verification of sampling and assaying |
| Significant intersections have been estimated by consultants to the company and cross checked. Twinned holes are not being used in the current programme which aims to test for mineralisation away from previously drilled areas. All data is entered into logging templates using codes on site and validated in appropriate software. No adjustment to assay data has been carried out. |
Location of data points |
| The drillhole collars have been located with a Garmin handheld GPS with a ± 5 m accuracy Co-ordinates presented are in UTM format using the WGS84 datum (zone 29N) A high-definition stereo satellite survey was conducted in 2020 over the main mineralised body to assist with the updated topography for the geological modelling and to improve the accuracy of artisanal mining depletions. This survey is deemed of sufficient quality to utilise in the Mineral Resource estimation. |
Data spacing and distribution |
| Drillholes are being drilled at spacings between 50 and 100m on section, with sections 200 - 400 metres apart. Drill spacing is intended to provide an initial test for mineralisation and may not be sufficiently close spaced for inclusion in a Mineral Resource estimation. |
Orientation of data in relation to geological structure |
| Drilling orientation is planned perpendicular to the regional structural trend (NNE). No sampling bias is expected. |
Sample security | The measures taken to ensure sample security. | Industry best practice has been applied to the drilling sampling processes carried out. Drilled samples were transported in a manner to prevent loss or cross-contamination. All samples were stored in a secure storage facility pending dispatch to laboratory in Bamako. In line with protocol, two people were used to transport the samples directly to the laboratory. Once at the laboratory, the samples were subject to the standard security measures of the laboratory. |
Audits or reviews |
| No audits have been completed. |
Section 2 Reporting of Exploration Results
(Criteria in this section apply to all succeeding sections.)
Criteria | JORC Code explanation | Commentary |
Mineral tenement and land tenure status |
| African Gold Group Mali SARL, a wholly-owned subsidiary of TRE, holds a mining permit No. PE 15/22 encompassing an area of 135.7 km² for the Kobada project area valid to 30 July 2045. Two adjacent exploration permits are also held, namely Kobada-Est (No. PR 18/957 over 77 km² valid to 15 August 2024 for three years) and Faraba (for which renewal was granted under Arrêté No. 2021-3226/MMP-SG effective 6 April 2021 for a further three years. An environmental permit No. 2021-0045 MEADD-SG was issued on 18 October 2021 relating to the oxides project.
