Bernard Aylward, CEO of Kodal Minerals, commented: "We are continuing to de-risk our flagship asset, the Bougouni Lithium Project, through the completion of our engineering studies. This important technical work represents significant components of our upcoming Feasibility Study and we are using the most experienced consultants to ensure we achieve the best result. The finalisation of the metallurgical test work programme, the review of the proposed transport, port facilities and mining contractors all feed into our mining optimisation studies and scheduling that will complete the feasibility work.
"Our exploration programmes continue to highlight the potential for further discoveries at both the Bougouni Project and Bougouni West, while our reconnaissance geochemical sampling at our gold projects in Côte d'Ivoire highlights additional value accretive opportunities for the Company and our shareholders.
"As previously announced, our Environmental and Social Impact assessment ('ESIA') has been lodged with the Mali Department of Environment and is moving through the process of review and approval, on which we look forward to updating our shareholders. Following this process, we anticipate finalising the various components of our Mining Licence application and lodging it with the Malian authorities for approval. This is a transitional time for Kodal and we would like to thank our operational and technical teams for their efficiency in undertaking the various studies we are undergoing as well as our shareholders for their ongoing support. I look forward to updating the market in due course."
Further Information
Mine Engineering
Mine engineering for the Feasibility Study is well advanced and Open Pit optimisations are nearing completion. Optimisations indicate that processing of Ngoualana's material through the DMS-only plant supports a mining plan focussed on extraction of Ngoualana ores for an initial period of 2-3 years. This option could provide the Company with a low-cost start-up operation that will be supplemented with the deferred installation of a flotation plant thereafter. This is continuing to be reviewed in studies and the Company is consistently looking at the best option for the development of the Project.
Detailed mine design and scheduling will commence following completion of the Open Pit optimisation review, and it is estimated that an initial mine life based on defined in-pit JORC resources will extend over an 8-10 year period, with average concentrate production in the order of 150,000-175,000 tonnes per annum of saleable concentrate product.
Study phase engineering design work is complete for mining geotechnical and non-process infrastructure, including office, camp, access roads, water and power facilities. With the recent completion of metallurgical test work, the mineral process flowsheet definition has been finalised and now allows the Company to move to finalising the plant engineering and supporting process infrastructure designs for the study phase.
Bulk Sample and Metallurgy
The bulk sample has been dispatched from the Dakar port and is expected to arrive in the Shandong province, China, in mid-October. Following arrival at port in Shandong, the material will be transported to the Ruifu Chemical lithium concentrator plant. This plant comprises a 2Mtpa processing plant incorporating a DMS circuit and floatation circuit. The proposed programme will see the bulk sample treated through the plant and all stages of processing will be monitored. Kodal will have its Project Manager and engineering process consultants on site to oversee the work. The results of this operational scale processing run will provide valuable plant scale recovery data to both the off-take partner and Kodal, the importance of which is often overlooked during the feasibility phase.
Product Transport Study
The Company's management team visited the preferred port facility for the load-out of final lithium concentrate, the San-Pedro Port in Côte d'Ivoire. A meeting was held with key representatives from the San Pedro Port Authority ('SPAP') who escorted the Company's management team on a tour of the facilities.
The visit included an inspection of the Port's container handling facility, and importantly their bulk materials handling establishments. SPAP is currently servicing exports of many bulk commodities, including iron ore and manganese concentrate, most notably, the iron ore export tonnes out of San Pedro are more than double the Company's future demands. Very positive feedback was received from SPAP personnel, expressing their interest to assist with the Project, and providing the confidence that the San Pedro Port has the knowledge and capacity to handle bulk material exports for the Bougouni Project.
The Company has also completed a survey of the proposed transport route from Bougouni to the San Pedro Port to confirm suitability for bulk commodity transport. This information has been supplied to the local logistic group who have confirmed suitability of the preferred route.
Exploration
Bougouni Lithium Exploration
Final assay results have been received for the exploration drilling completed at the Marigo Prospect, Bougouni Lithium Project, and at the Mafele Concession, Bougouni West Project.
Marigo Prospect
The Marigo Prospect ('Marigo' or the 'Prospect') is defined by geological mapping that identified outcropping pegmatite veins with abundant coarse spodumene minerals. The Prospect is located mid-way between the Boumou and Sogola-Baoule prospects and the pegmatite veins are interpreted as striking in an east-west direction similar to the other prospects in the region.
This first campaign drilling programme consisted of 4 drill holes for 474m, with all holes intersecting pegmatite. The assay results confirm that the pegmatites are mineralised, however in this location the lithium mineralisation is low tenor. The review of the drill hole location and drill chips indicate that the degree of weathering and proximity to a creek area may have led to a dilution of lithium in the weathering process. The wide zones of shallow mineralisation are very encouraging, and the Company is focussing on the strike extensions of the Prospect in areas where there is less weathering and potential impact of dilutive activity. This weathering effect has previously been noted at the Ngoualana and Sogola-Baoule prospects where the zones closest to active drainages and deeper weathering have demonstrated reduced lithium grades, similar to the Finniss project in Darwin of Core Lithium and Greenbushes of Talison Lithium in Australia.
Mineralised intersections for the reverse circulation ('RC') drilling calculated using a 0.2% Li2O lower cut-off, maximum 2m internal continuous dilution are tabled below:

Notes: Drill holes are RC drill holes. Drill holes prefixed MDRC* are from the Marigo prospect located within the Madina concession. Drill holes have been sampled on a 1.0 basis with samples collected via a riffle split system. Drill hole collars are surveyed using a differential GPS with sub 1-metre accuracy, coordinate system WGS84 - Zone 29N, and all holes are survey down-hole for dip and azimuth on approximately 30m intervals. All drill holes are geologically logged, and sampling for analysis in based on geological boundaries. Samples analysed by ALS Global. Assay results are reported as Li% and converted to Li2O% by a factor of 2.153.
Mafele Concession
The Mafele Concession is located approximately 25km to the west of the Bougouni Lithium Project and was acquired by Kodal in February 2019. The maiden drilling programme was a reconnaissance drill test of several geological and geophysical targets.
All drill holes intersected lithium mineralised pegmatite bodies, however, the lithium grade was generally low. Further exploration activity will focus on targeting the pegmatite ones in areas of less weathering and attempt to define zones of thicker pegmatite veins.
Côte d'Ivoire Gold Exploration
Kodal maintains a suite of prospective gold exploration gold projects in Mali and Côte d'Ivoire. During the wet season, the Company has taken the opportunity to send a field crew to Côte d'Ivoire to undertake a programme for regional geochemical sampling at the 100% owned Dabakala and Korhogo projects in north-central Côte d'Ivoire.
The geochemical sampling consisted of conventional surface samples and termite mound sampling (where available) on a nominal 2km x 200m sample spacing at Dabakala (225 samples), infilling an area of previously defined gold anomalism, and a nominal 1km x 200m spacing at Korhogo (190 samples) targeting infill at several gold anomalous zones and structural targets within the Korhogo project.
The Dabakala project is a single concession in central Côte d'Ivoire where previous work completed by the Company highlighted an extensive surface geochemical anomaly and field geological mapping indicated the association of sheared and altered geology associated with the anomaly. This is a large surface anomaly, extending for over 10km of strike and up to 800m in width and exploration is at an early stage. The follow-up work completed by the company infilled the anomaly to a nominal 1km x 200m spacing over the key anomaly (and notes that still is very wide and reconnaissance level) and assay results received confirm the anomaly with results up to 97ppb returned and confirming the extent of the anomaly. Further work is required to define this prospect prior to initial drill testing.
The Korhogo project is a single concession is north central Côte d'Ivoire and several phases of geochemical sampling has defined surface geochemical anomalies. The recent sampling by the company has confirmed gold anomalous zones extending for over 2kms in strike and up to 600m in width. Further exploration is required to review these targets and prioritise further work.
The Company is continuing to review opportunities for the prospective suite of gold projects.
