Discovery at Kobada Unlocks Newly Identified Structure
TORONTO, May 16, 2023 (GLOBE NEWSWIRE) — Toubani Resources, Inc (ASX: TRE) (“Toubani Resources” or the “Company”) is pleased to announce the Kobada West discovery, a never-before drilled target less than 1km from the Kobada Main deposit in southern Mali. The Kobada project hosts 3.1Moz in Mineral Resources which occurs over a 4.5km strike length and is predominantly oxide and open pittable.
- First ever drill holes at Kobada West have delineated continuous, near surface oxide gold mineralisation with consistent grades and thicknesses section-to-section
- Kobada West is interpreted to lie on a parallel structure less than 1km west of the Kobada Main deposit, yet no previous drilling had been undertaken and is outside of the current Mineral Resource
- Recent drilling has identified shallow, oxide mineralisation on every section drilled to date over the current strike length of 600 metres which remains open along strike and at depth
- Significant intersections include:
- 9m at 1.72g/t incl. 2m at 6.26g/t
- 1m at 11.3g/t and 5m at 1.26g/t
- 5m at 1.24g/t and 3m at 0.93g/t
- 11m at 0.55g/t, 2m at 2.66g/t and 3m at 1.12g/t
- Kobada West results confirm gold mineralisation has been intersected at all of the five planned extensional targets drilled by Toubani in 2023, extending overall strike extent of mineralisation defined by drilling at the project from 5km to 11km
- Drilling results affirm Toubani’s overall strategy of an oxide-dominant project of scale at Kobada with optimisation work streams underway
Chief Executive Officer, Phil Russo commented: “The consistency and continuity of mineralisation at Kobada West is very pleasing to see and is validation that the more we drill at Kobada, the more mineralisation is uncovered. Further, to discover this extensive mineralisation right next door to the main Kobada resource is a fantastic result. For a project of scale and maturity like Kobada to still be able to make new discoveries is such a rare combination and with our 2023 drill program now intersecting new mineralisation across all planned targets, we have had an exceptional success rate. Toubani’s vision of defining a long-life, oxide-dominant project of scale is supported by our drilling success to date and we look forward to demonstrating this potential as our optimisation efforts advance in the coming months.”

Drilling Results and Commentary
Kobada West is located on a parallel structure just 1km north-west of the Kobada Main Deposit (Figure 1). The target area was identified by the presence of artisanal workings as well as historical surface sampling. The number of holes drilled at this target was increased during the drill program due to recent artisanal activity observed by Toubani’s geologists as well as logging of the initial drill holes.
Drilling was carried out on four sections spaced 200 metres apart as shown on Figure 2. Shallow oxide gold mineralisation was intersected on every section, over a strike length of 600m with good continuity section to section, and consistent grade and thickness. Gold mineralisation remains open along strike and depth. Results are detailed in Appendix 1 and include:
- 9m at 1.72g/t from 63m incl. 2m at 6.26g/t from 63m (KW1/22_P003)
- 1m at 11.3g/t from 129m and 5m at 1.26g/t from 116m (KW22_P003)
- 5m at 1.24g/t from 78m, 4m at 0.67g/t from 88m and 3m at 0.93g/t from 106m (KW22_P009)
- 11m at 0.55g/t from 16m, 2m at 2.66g/t from 58m and 3m at 1.12g/t from 63m (KW22_P002)
- 2m at 0.51g/t from 92m and 2m at 3.22g/t from 124m (KW1/22_P006)
- 1m at 5.50g/t from 103m (KW1/22_P001)
- 5m at 0.80g/t from 90m (KW1/22_P005)

Exploration and Optimisation Work Program
Toubani’s 13,750m drill program has recently been completed with outstanding results due in the coming weeks from Kobada North, Kobada Junction and Foroko. The success at Kobada West has seen the overall strike extent of mineralisation at Kobada defined by RC drilling significantly increased to 11km, from 5km previously.
At Kobada West, we are planning step out drilling along strike to the north and south to test for extensions to this new gold discovery as well as infill RC drilling to reduce the section spacing to 100m for resource modelling.
Optimisation work streams continue to advance with an update due later in the June quarter. The Company is investigating the potential of an oxide-dominant project of scale at various throughput scenarios.
This announcement has been authorised for release by the Board.

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|
||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.
||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.
||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.
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.|
