Spodumene Pegmatite Discovery at Esperança Project in Brazil Yields LIBS Results up to 4.04% Li2O
ASX Announcement 18[th] November 2024
Lightning Minerals (L1M or the Company) is delighted to announce the discovery of spodumene within a lithium bearing pegmatite at the Company’s recently acquired Esperança project. The discovery supports the Company’s approach to exploration in the district and its positive assessment of the prospectivity within the Lithium Valley region Minas Gerais, Brazil.
The discovery has been made during early-stage exploration programs which include project scale geological mapping, ground reconnaissance, and soil sampling. These early-stage programs remain ongoing with further results to come over the coming weeks. The discovery supports the Company’s exploration thesis and uplifts the remaining prospectivity across all three project areas: Canabrava, Caraíbas and Esperança projects.
HIGHLIGHTS
-
Artisanal excavations reveal a lithium bearing pegmatite with elongate crystalline spodumene crystals up to 50cm in length
-
LIBS (Laser Induced Breakdown Spectroscopy) results of spodumene crystals return up to 18,800 ppm Lithium, or 4.04% Li2O
-
Discovery provides walk up drill target for fully funded drilling campaign to begin Q1 2025
-
Soil sampling and geological mapping continues across the Esperança, Canabrava and Caraíbas projects with further results due over the coming weeks
l 6 505 Littl ~~e Collins St Melbour~~ Cautionary Note: ne VIC 3000 Australia | [email protected] | (08) 9429 8806 Visual estimates of mineral abundance should never be considered a proxy or substitute for laboratory analyses where concentrations or grades are the factor of principal economic interest. Visual estimates also potentially provide no information regarding impurities or deleterious physical properties relevant to valuations. Throughout this document the company refers to “spodumene” or “spodumene-pegmatite”. While the Company is very encouraged by its geological observations, no quantitative assessment of mineralisation is possible for those observations, and they remain without certified laboratory assay. Spatial information regarding the pegmatite is not yet available and therefore no estimate of true width is given. Further, no forecast is made of whether this or drill testing will deliver ore grade intersections. The observed presence of spodumene within pegmatite does not necessarily equate to economic grades of lithium mineralisation until confirmed by chemical analysis which is currently underway. It is not possible to estimate the concentration of lithium in mineralisation by visual estimates, and the SciAps Z-903 handheld LIBS analysis reports only a tiny fraction of the crystal and is considered qualitative, whole rock chemical analysis from a certified laboratory and Raman spectroscopy will determine the true lithium content and confirm the mineral species respectively. Laboratory results of the samples are expected to be received and announced in Q1 2025.

Lightning Minerals Managing Director Alex Biggs said , “I am highly encouraged by these results from Brazil. As I have spoken about, as a team we are committed to discovery and completing our works in a diligent and structured manner, the proof of which is in these results. The Company is progressing its projects in Brazil quickly and cost effectively and generating significant results for the business which we feel will be transformational. I am proud of and congratulate our geology teams both in Australia and Brazil who have conducted themselves in a professional and astute manner which has been crucial in making a discovery such as this. This is a great first step for us in Brazil and is testament to the prospectivity of the region as I have discussed previously. We look forward to drilling in Q1 2025 and further results to come imminently from all three project areas in Brazil. I would also like to thank our shareholders who have supported our vision and exploration strategy. As a Company we are firmly committed to the lithium thematic and firmly committed to Brazil where we see significant potential moving forwards”.
Lithium Discovery at Esperança Project
During geological mapping fieldwork conducted in mid-November 2024 field geologists encountered a previously unknown historical artisanal mine within the Esperança project area. The site presented with a small access which opened into a set of sub vertical shafts sunk several meters into schists of the Salinas formation. Upon investigation the geology team has discovered pegmatitic lithologies in the walls of the excavations, of which the suite of minerals indicates inclusion of macro crystalline (up to 50cm) elongate crystals of spodumene as shown in Figure 1(a) and Figure 1(b).

The Company’s geologists have collected selective mineral specimen grab samples in sample VLM207 (Figure 2). Six separate minerals have been analysed via a SciAps Z-903 hand-held LIBS (Laser-Induced Breakdown Spectroscopy) device which has returned lithium endowment of up to 18,800 ppm lithium, which equates to a lithium oxide percentage of 4.04% Li2O.
The SciAps Z-903 handheld LIBS device is considered a qualitative analysis technique only and is used as an in-field preliminary check to establish if a mineral is lithium-bearing. Certified laboratory assays are required

to provide accurate, quantitative analysis. A table of the six SciAps Z-903 handheld LIBS results testing the spodumene crystals is shown in Table 1. A full table of results are presented in Appendix 2, Table 2.
While the current field observations indicate that the mineral identified is a lithium-bearing mineral, the percentage of lithium produced from the LIBS analyser does not correlate to an accurate quantitative measurement of the lithium concentration of the mineral itself, or to the overall grade of the pegmatite.

Under UV light the mineral samples from VLM207 fluoresce in the orange spectrum when activated by 365nm wavelength UV light which is common for spodumene crystals in the region. The weathered spodumene crystals show a light orange fluorescence as shown in Figure 3a some less weathered portions of the spodumene crystal remain and exhibit a stronger fluorescent response with deeper orange colours as those shown in Figure 3b. The accessory green highly fluorescent mineral is yet to be confirmed.
The Company takes seriously the reporting of lithium bearing minerals and in this instance is confident to report the presence of spodumene given the presentation of crystal habit at the excavation wall, the elevated LIBS lithium content, UV light fluorescence consistent with spodumene colouration in the region. This is combined with the confidence of identification of weathered spodumene from the local highly experienced geology team.
l 6 505 Little Collins St Melbourne VIC 3000 Australia | [email protected] | (08) 9429 8806 Follow up work to confirm the whole rock lithium content is underway, as is sample collection for Bruker Bravo Raman Spectroscopic analysis to confirm the mineral species. This is the first instance where spodumene, a globally significant source of lithium, has been identified within the Lightning Minerals Brazilian Projects.
Surface Expression of Pegmatites
Following the identification of the lithium minerals at the site, the geology team has mapped the surrounding area to understand the orientation of any outcropping lithologies. The early first pass mapping surrounding the site is shown in Figure 4. First rock samples collected from the site are shown in Appendix 3 Table 2. Early indicators are positive with the mineralised pegmatite outcrop displaying a shallow dip to the south-east. Samples are being collected and the area will continue as a focus for the Company to understand the outcrop presentation, orientation, and structural setting for drill testing scheduled for Q1 2025. At this stage the scale and orientation of the discovery beyond the artisanal mine site is under evaluation and remains unknown.

Ongoing Works in Brazil and Exploration Thesis
Exploration for pegmatites began during June 2024 with project scale geological mapping and soil sampling programs begun across the three projects as part of an aggressive early-stage exploration program. The geological thesis for exploration targeted pegmatites associated with Neoproterozoic Araçuaí orogeny G4 S-type granites that may have been emplaced into schists of the Salinas Formation. To enable the on-ground execution the Company was successful in engaging the support of a highly experienced team of Brazilian geologists with a track record of success in the region, the IP this team has brought the Company is highly l 6 505 Little Collins St Melbourne VIC 3000 Australia | [email protected] | (08) 9429 8806 valued and has been integral to making a discovery in the region.
Initial Phase 1 soil sampling and ground reconnaissance works across the Canabrava, Caraíbas and Esperança projects are nearing completion with multiple results expected over the coming weeks. Phase 1 results from the Canabrava project have identified multiple pegmatites and lithium in soil anomalism up to 113ppm Li which is highly encouraging (ASX Announcement 03 October 2024). Drill targeting is now being discussed with a view to inaugural drilling in Q1 2025.

Appendix 1: Esperança – JORC Code 2012 Table 1 Criteria
The Table below summarises the assessment and reporting criteria used for exploration results for the Esperança Exploration Project and reflects the guidelines in Table 1 of The Australasian Code for the Reporting of Exploration Results, Mineral Resources and Ore Reserves (The JORC 2012 Code).
Section 1 - Sampling Techniques and Data
| 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. |
• Data in this document relates to field visual identification of minerals and SciAps Z-903 Handheld LIBS (Laser-Induced Breakdown Spectroscopy) results which are both considered qualitative at best. • Sample VLM207 is collected at the discretion of field geologists targeting spodumene minerals to confirm the mineral species. The LIB’s test work on these samples relates only to a fraction of the mineral and does not represent the whole rock lithium content. • The LIBS (Z-903) analyser is calibrated daily prior to mineral analysis. • Rock chip samples were collected at the discretion of the field geologist, this method is appropriate given the early stage of exploration at the Esperança Project • Sample site locations are recorded using a Garmin Map 62s handheld device and are reported in projection SIRGAS 2000 / UTM 23S |
| Drilling techniques | Drill type (eg core, reverse circulation, open-hole hammer, rotary air blast, auger, Bangka, sonic, etc) and details (eg core diameter, triple or standard tube, depth of diamond tails, face-sampling bit or other type, whether core is oriented and if so, by what method, etc). |
• No drilling is being reported |
| Drill sample recovery | Method of recording and assessing core and chip sample recoveries and results assessed. Measures taken to maximise sample recovery and ensure representative nature of the samples. Whether a relationship exists between sample recovery and grade and whether sample bias may have occurred due to preferential loss/gain of fine/coarse material. |
• No drilling is being reported |
| Logging | Whether core and chip samples have been geologically and geotechnically logged to a level of detail to support appropriate Mineral Resource estimation, mining studies and metallurgical studies. Whether logging is qualitative or quantitative in nature. Core (or costean, channel, etc) photography. The total length andpercentage of the relevant intersections logged. |
• No drilling is being reported • Descriptions of rock samples are contained in Appendix 2 – Table 2. • Logging and mineral estimates are qualitative and do not support mineral resource estimation, mining studies and/or metallurgical studies. |
| Sub-sampling techniques and sample preparation |
If core, whether cut or sawn and whether quarter, half or all core taken. If non-core, whether riffled, tube sampled, rotary split, etc and whether sampled wet or dry. |
• Sample VLM207 is collected at the discretion of field geologists targeting spodumene minerals to confirm the mineral species. The LIB’s test work on these samples relates only to a fraction of the mineral and does not represent the whole rock lithium content. |
==> picture [842 x 57] intentionally omitted <==
==> picture [842 x 53] intentionally omitted <==
| For all sample types, the nature, quality and appropriateness of the sample preparation technique. Quality control procedures adopted for all sub-sampling stages to maximise representivity of samples. Measures taken to ensure that the sampling is representative of the in situ material collected, including for instance results for field duplicate/second-half sampling. Whether sample sizes are appropriate to the grain size of the material being sampled. |
||
|---|---|---|
| Quality of assay data and laboratory tests |
The nature, quality and appropriateness of the assaying and laboratory procedures used and whether the technique is considered partial or total. For geophysical tools, spectrometers, handheld XRF instruments, etc, the parameters used in determining the analysis including instrument make and model, reading times, calibrations factors applied and their derivation, etc. Nature of quality control procedures adopted (eg standards, blanks, duplicates, external laboratory checks) and whether acceptable levels of accuracy (ie lack of bias) andprecision have been established. |
• A SciAps Z-903 LIBS device has been used for spot sample readings of minerals of interest. The device is calibrated each day, and before analysis is begun. QAQC standards are used every 10-15 readings as consistency checks. Readings times are approximately 3 to 5 seconds and are standard for the device. The device is calibrated to a lithium profile supplied by SciAps prior to use. • Handheld LIBS is expected to differ from laboratory assay results and can read above theoretical maximum values. They should not be used to replace assays or indicate whole rock grade. |
| 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. |
• No verification will be undertaken for these initial samples as they will not be used in any resource estimate. Samples will be submitted to certified laboratories for whole rock analyses. • All data generated from the mapping of the pegmatite has been uploaded into Lightning Minerals data storage and been checked by geologists. • LIB’S readings have been downloaded directly from the device. |
| Location of data points | Accuracy and quality of surveys used to locate drill holes (collar and down-hole surveys), trenches, mine workings and other locations used in Mineral Resource estimation. Specification of the grid system used. Quality and adequacy of topographic control. |
• Handheld Garmin GPS instruments were used to geo locate each sample location, these instruments are understood to be accurate within a ±5m in the horizontal and vertical planes. • The level of topographic control offered by a handheld GPS is considered sufficient for early exploration activities. • All samples were collected in the SIRGAS 2000 / UTM zone 23S |
| Data spacing and distribution |
Data spacing for reporting of Exploration Results. Whether the data spacing, and distribution is sufficient to establish the degree of geological and grade continuity appropriate for the Mineral Resource and Ore Reserve estimation procedure(s) and classifications applied. Whether sample compositing has been applied. |
• The sample spacing is considered appropriate for the reporting of the exploration results. • No Mineral Resource or Ore Reserve Estimates have been completed. |
| Orientation of data in relation to geological structure |
Whether the orientation of sampling achieves unbiased sampling of possible structures and the extent to which this is known, considering the deposit type. If the relationship between the drilling orientation and the orientation of key mineralised structures is considered to have introduced a sampling bias, this should be assessed and reported if material. |
• Not Applicable at this early stage of reporting with sampling ongoing. |
| Sample security | The measures taken to ensure sample security. | • The chain of custody for sampling procedures and sample analysis was managed by the contract geological consultants duringcollection |
==> picture [842 x 57] intentionally omitted <==

Section 2 - Reporting of Exploration Results
| Criteria | JORC Code explanation | Commentary |
|---|---|---|
| Mineral tenement and land tenure status |
Type, reference name/number, location and ownership including agreements or material issues with third parties such as joint ventures, partnerships, overriding royalties, native title interests, historical sites, wilderness or national park and environmental settings. The security of the tenure held at the time of reporting along with any known impediments to obtaining a licence to operate in the area. |
• The Esperança Project is located approximately 25km south-south east of the town of Salinas, Minas Gerais, Brazil. • The Esperança Project area totals ~11.06km2and comprises one granted exploration licence 301033/2013 • The tenement is considered in good standing at the time of this report. |
| Exploration done by other parties |
Acknowledgment and appraisal of exploration by other parties. |
• The Esperança Project is at a very early stage and little to no recorded work has been completed by prior explorers. |
| Geology | Deposit type, geological setting and style of mineralisation. | • No known mineral deposits occur within project tenure. • The Esperança Project geology comprises Neoproterozoic age sedimentary rocks of Araçuaí Orogen intruded by pegmatites interpreted to originate from the fractionation of magmatic fluids from the peraluminous S-type post tectonic granitoids of Araçuaí Orogen. • The target commodityis hardrock lithium within lithium-caesium-tantalumpegmatites. |
| Drill hole Information | A summary of all information material to the understanding of the exploration results including a tabulation of the following information for all Material drill holes: oeasting and northing of the drill hole collar oelevation or RL (Reduced Level – elevation above sea level in metres) of the drill hole collar odown hole length and interception depth, ohole length. If the exclusion of this information is justified on the basis that the information is not Material and this exclusion does not detract from the understanding of the report, the Competent Person should clearly explain why this is the case. |
• No drillhole information is reported. • No material information has been excluded from this report, qualitative analytical results have been adequately communicated and described within the body of this report. |
| Data aggregation methods |
In reporting Exploration Results, weighting averaging techniques, maximum and/or minimum grade truncations (eg cutting of high grades) and cut-off grades are usually Material and should be stated. Where aggregate intercepts incorporate short lengths of high-grade results and longer lengths of low grade results, the procedure used for such aggregation should be stated and some typical examples of such aggregations should be shown in detail. |
• No levelling of the raw geochemical data was undertaken. • Plan images have been generated using QGIS software. • No metal equivalent values are reported. |
| Relationship between mineralisation widths and intercept lengths |
These relationships are particularly important in the reporting of Exploration Results. If the geometry of the mineralisation with respect to the drill hole angle is known, its nature should be reported. If it is not known and only the down hole lengths are reported, there should be a clear statement to this effect(eg ‘down hole length, true width not known’). |
• No drillhole information is reported. • There is insufficient data provided by the mapping and qualitative results contained within this report for a relationship between pegmatite and mineral resources to be reported. |
==> picture [842 x 57] intentionally omitted <==
==> picture [842 x 53] intentionally omitted <==
| Diagrams | Appropriate maps and sections (with scales) and tabulations of intercepts should be included for any significant discovery being reported These should include, but not be limited to a plan view of drill hole collar locations and appropriate sectional views. |
• Appropriate reporting of results has been included in the body of this announcement; the plans, or lack thereof suitably represent the nature of the results. |
|---|---|---|
| Balanced reporting | Where comprehensive reporting of all Exploration Results is not practicable, representative reporting of both low and high grades and/or widths should be practiced to avoid misleading reporting of Exploration Results. |
• Comprehensive reporting of results within the Esperança Project has been included in Appendix 1. • The selective nature of the sampling is well communicated in the document. Whole rock chemical analyses results, and spectrographic analyses of minerals is underway. |
| Other substantive exploration data |
