Figure 1: Locality of FL1 Faraba and Gouna permits, with the drilling to take place over the Blakala prospect within the Gouna Permit.
Goulamina and Blakala have been highlighted in previous reports as the two preferred Tier 1 targets in Mali (ASX:FL1 04/10/23), with Goulamina being the fifth largest spodumene deposit globally[1] . A detailed channel sampling program of all the trenches at Blakala is currently taking place, with results for these samples expected within the next 6 to 8 weeks. Apart from confirming the significant spodumene content of the initial results, the trenches have also confirmed some very significant thicknesses of some of the pegmatites from 10m (Figure 4) and up to 40m. The assay results from the 15 samples within the Blakala prospect average 1.60% Li2O, with a further 3 samples within the wider Gouna permit area averaging 1.32% Li2O (Table 1). The analysis was completed to confirm the visual mapping of the

trenches showing significant spodumene content and with large to very large crystals of up to 15cm being identified (Figure 3).
The targeted extension diamond drilling program at Blakala will test the strike and depth extensions (up to 300m in vertical depth). The drilling program has been designed to delineate the Blakala pegmatites in order to calculate a maiden JORC Mineral Resource in H1 2024.
Drilling will follow the targets identified by the results from the initial confirmatory analysis (Figure 2). The analysis was undertaken at the Shiva lab, Bangalore, India.

Figure 2: Blakala Block within Gouna licence, trenching sample results
From the trench mapping, it was seen that the pegmatites are unzoned with quartz, microcline, albite, muscovite, biotite and iron oxide and contain well developed grains of spodumene (Figure 3). The spodumene mineral is distributed almost uniformly throughout the length and width of the pegmatites. Spodumene is pale green to white in colour and occurs in the form of blades and needles up to 15 cm in length (Figure 3). These spodumene grains are uniformly oriented across the strike of the pegmatites and are oriented towards North 110° in all the pegmatites within this area (Figure 3).

Faraba Prospect – Highly Encouraging First Pass Drilling Second-tier Faraba Permit
The Faraba Prospect is a second-tier target for FL1 as historic work indicated that, whilst it has extensive spodumene bearing pegmatites, the regional geology lends itself to thinner widths and thicknesses when compared to pegmatites such as those found at Goulamina or Blakala.
Historical geological prospecting by Russian geologists was carried out in 1963-64 in the central part of the Bougouni pegmatite field. During this prospecting program diamond drilling took place, with two of the diamond drillholes located in the Faraba Prospect area (refer Figure 5). The results of the Russian prospecting indicated a high spodumene content within the pegmatites of these two historical drillholes, and results from this historical program was used for target generation purposes only. Two confirmatory diamond drillholes (FDD1, FDD2) were drilled by FL1 to twin the historical Russian drilling (refer Figures 5 and 6, with the standpipe of the historical drillhole visible in the foreground in Figure 6).

Figure 6: Photo of twinned Russian diamond drillhole in foreground with FL1’s FDD2 diamond drillhole being drilled in background.
The two FL1 drillholes were set up parallel to the historical Russian holes, with a distance of approximately 10m from the historical collars. The two holes were set up with an alignment of -70 degree inclination to 340 degrees’ azimuth. Orientation of the core was performed using a new REFLEX Act III device, with the core then accurately orientated using the orientation information. The orientation line (bottom of the hole) was then used for all core logging and sampling work with meter marking, core recoveries, rock quality designation (RQD), detailed lithological and structural logging, as well as sample marking taking place using the orientation line. Wet and dry photos of all core was undertaken pre sample cutting, and the sampling information was then marked on the retention core after sampling and post sampling photos being taken of the sampled intersections.

Encouragingly, multiple stacked lithium bearing spodumene pegmatites were encountered in each of the two holes (refer Figure 7 and Table 2). Four mineralised pegmatites of between 1.61m to 2.86m (2.86m pegmatite shown in BOX-17, Figure 8) in thickness were intercepted in FDD1 and 13 mineralised pegmatites intercepted in FDD2 (Figure 7), with 6 being prominently mineralised with thickness of 0.99m to 3.46m. The mineralised pegmatites were intercepted from surface down to approximately 60m in depth (true vertical depth) with weighted average grades ranging from 0.99 to 1.95% Li₂O. The highest individual sample result was 2.55% over a 1m intersection thickness of Li₂O from sample K6808 in FDD1 (sample can be seen in BOX-17, Figure 8). The weighted intersection of the two pegmatites (Zone 3 and 4, Table 2), as well as the unmineralized interburden shown in Figures 3 and 4, is 1.03% Li₂O over a 7.97m intersection thickness (Table 2).
The two holes were located 300m apart and further infill drilling will take place on the permit.

Section 1 Sampling Techniques and Data
(Criteria in this section apply to all succeeding sections.)

Criteria JORC Code explanation Commentary |
|---|---|
| Sampling techniques • Nature and quality of sampling (eg cut channels, random chips, or specific specialised industry standard measurement tools appropriate to the minerals under investigation, such as down hole gamma sondes, or handheld XRF instruments, etc). These examples should not be taken as limiting the broad meaning of sampling. • Include reference to measures taken to ensure sample representivity and the appropriate calibration of any measurement tools or systems used. • Aspects of the determination of mineralisation that are Material to the Public Report. • In cases where ‘industry standard’ work has been done this would be relatively simple (eg ‘reverse circulation drilling was used to obtain 1 m samples from which 3 kg was pulverised to produce a 30 g charge for fire assay’). In other cases more explanation may be required, such as where there is coarse gold that has inherent sampling problems. Unusual commodities or mineralisation types (eg submarine nodules) may warrant disclosure of detailed information. • • • • • • • • • • • |
Trenching at Blakala Prospect in Gouna Permit Trenching at Blakala is ongoing, trenches are dug perpendicular to the pegmatite vein directions. Initial samples were taken of the pegmatites to determine visual logging of significant Spodumene content. Comprehensive channel sampling of all trenches and pegmatite intersection is to be initiated. Diamond drilling at Faraba licence Diamond drilling of two HQ core size holes was used to obtain core for sampling and analysis. All logging and sampling took place according to detailed Standard Procedure documents. The core was first accurately fitted to the orientation line (bottom of hole) of the orientated core accurately drawn with a permanent paint marker; logging took place using the orientation line, and sampling was then marked on the retention portion of the core. ½ core sampling took place, on the same side of the core from the orientation line and the other side (closest to the geologist) was kept as reference. Before and after sampling photos were taken of the core, with all the sample marks clearly visible. Sampling was done lithologically, in the thicker pegmatite veins the samples were generally of a 1m intersection width. The average sample length is 0.85m. with the shortest sample length being 0.30m. This minimum sample length of 0.30m during ½ core HQ core size sampling supplies a sufficient amount of core for analyses. Archimedes wet-dry bulk density measurements were done for each sample interval. Core samples were bagged, with an alpha-numerical sample ticket inserted for each sample. |

Commentary
-
Two Diamond wireline drillholes of HQ core size took place at Faraba; no drilling to date at Blakala.
-
The drill core was downhole orientated using the electronic REFLEX ACT III tool; a core orientation line was marked for all geological and sampling depth information.
==> picture [299 x 208] intentionally omitted <==
-
Diamond drilling is considered a standard industry drilling technique for vein or pegmatite deposits.
-
The drilling rig used was a YS1500 with a Cummins QSB 6.7 engine. Drill rod lengths were a standard 3m.
-
Both drillholes were inclined at -70°.
-
The drilling onsite is governed by a Daimond Drilling Guideline to ensure consistency in application of the method between geologists and drillers.

Core logging took place only after careful fitting of all core, followed by the orientation of the core from the Reflex orientation data, followed by core recovery and RQD data collection. Detailed and appropriate lithological, structural and weathering logging took place on the full core using the orientation line for interval measurements. All logging data is entered into the project drillhole database. Sampling intervals were then marked on the core, with wet and dry core photography taking place, clearly showing the sample intervals (see Figure 8 in main body as example). After core cutting, the sampling information is transferred to the face of the retained core and wet and dry photographs were again taken of the sampled core boxes. |

Trenching at Blakala Prospect in the Gouna Permit Trenching at Blakala is ongoing, trenches are dug perpendicular to the pegmatite vein directions. In order to collect representative samples, channel samples across the pegmatite were collected and analyzed\ for lithium. Diamond drilling at Faraba licence All spodumene mineralised portions of the core were identified for sampling and marked up. Maximum sample length was one meter. Sample marking of the core was done with permanent markers, including depths and sample numbers. Sample numbers and depths were marked onto the cut side of the core after sampling. Photos were taken of the core before and after splitting/sampling both wet and dry. Diamond drilling of two HQ core size holes was used to obtain core for sampling. Core was ½ cut with a diamond cutting machine – ½ HQ core of up to 1m in length is of appropriate size for the mineralisation and deposit. Standards introduced include SARM 181 and AMIS 340,adittionally, blanks were also introduced in the sample stream for QAQC. Density studies were conducted by the ALS prep facility at Bamako. |

All the trench samples were processed at Bamako, Mali and were then couried to India to be analysed. The samples were analysed at the Shiva laboratory, Bangalore. Diamond drilling at Faraba licence Analysis results of 34 pegmatite samples including 11 from borehole FDD1 and 23 from borehole FDD2 have been received. Analyses was undertaken at the ALS laboratory in Johannesburg. Li% was analysed and a conversion factor of 2.153 was used for the conversion of %Li to %Li2O. An AMIS 343 CRM and a blank was inserted by ALS on behalf of Intermin, in Johannesburg South Africa, as no CRM was available onsite at the time of drilling. All QAQC controls returned expected results within permitted the parameters. This includes an internal ALS QAQC procedure involving 4 CRMs (2 AMIS 340 and 2 SRM181) 2 blanks, and 2 duplicates. The laboratory analyses and procedures are consistent with and applicable to the style of mineralisation. |
| Verification of sampling and assaying • The verification of significant intersections by either independent or alternative company personnel. • The use of twinned holes. • Documentation of primary data, data entry procedures, data verification, data storage (physical and electronic) protocols. Discuss any adjustment to assay data. • • • • |
On site logging took place with experienced geologists, and a senior company geologist checking all the logging being undertaken. A senior GeoActiv Pty Ltd geologist observed the logging and some of the pegmatite intersections. The geological field data is manually transcribed into a master Microsoft Excel spreadsheet which is appropriate for this stage in the exploration program. The raw field data is checked in the Microsoft Excel format first to identify any obvious errors or outlier data. The data is then imported into a Microsoft Access database where it is subjected to various validation queries. Li% was analysed and a conversion factor of 2.153 was used for %Li to %Li2O. |

Blakala Prospect Blakala and Gouna prospects are Palaeo-Proterozoic in age. The regional lithological assemblages comprise of felsic intrusives such as granite, granodiorites, and schists of variable composition and laterite. The schists have a metasedimentary origin with coarse grains of quartz and mica, which have been subjected to multiple deformations to form schists. The pegmatites are a pale greyish-white colour, fresh hand specimen shows a whitish-earthy matrix of feldspar with phenocrysts of spodumene, quartz and muscovite (figure below). The pegmatites have a varied width from a few centimetres to up to 52.7 meters where the two separate pegmatite bands merge together. Faraba licence The presence of vein quartz and quartzite occur as small lensoidal bodies in close proximity to pegmatite bodies. The pegmatites invariably had sinistral and dextral dislocations by both local small-scale faults and regional large-scale faults. The pegmatite veins are found predominantly emplaced within the granodioritic plutonic bodies within sheared zones parallel to the trend of N60°E. However, pegmatite emplacementis alsofound on N40°W |
