Significant lithium, tantalum and caesium mineralisation indicate the pegmatites at Horse Rocks are part of a highly fractionated LCT pegmatite system and warrant further exploration and drilling at the project.
Commenting on the results, LRD Exploration Manager Georgina Clark:
“The analytical results from our initial drilling at Horse Rocks Lithium Project have produced further encouragement for our exploration team. The anomalous lithium results and highly fractionated pegmatites demonstrate we are in the right neighbourhood for an economic lithium discovery.
The technical team will evaluate trends observed within the fractionation ratios and look to plan follow-up work along strike and at depth in order to identify potential economic grade lithium bearing pegmatites for a Phase 2 drilling program. We know we are in the right rocks with the right LCT ratios to make a significant lithium discovery, the Company is excited to get Phase 2 of the drilling underway.”

DRILLING RESULTS
The first-pass RC drilling program was designed to test for pegmatite hosted lithium mineralisation within the Horse Rocks Lithium Project. In total, 4,223m were drilled in 52 holes, in areas of geochemical anomalism.
Multiple significant intercepts were returned from the drilling, including elevated Li, Ta and Cs. Pegmatite was intercepted in 47 of the 52 holes, with 43 drillholes containing pegmatites that display zones of high to moderate fractionation (see further details below).
Drilling was successful in determining the geometry of the pegmatites, with a low angle east dip (5° to 30°) observed in most pegmatites, further evidence that the source granite is the Depot Granodiorite located to the east, between Horse Rocks and Mt Marion lithium mine. The pegmatites varied in thickness, from narrow ‘veins’ of less than one metre wide to broad intrusions over 60 metres in width.
Most of the drilling was completed in the centre of the project at the largest geochemical anomaly. Over half of the pegmatites within the main geochemical anomaly in this area of the lease have elevated lithium values (more than 0.1% Li2O), with assays of over 0.2% Li2O returned in five drillholes (Figure 3). Drilling targeted geochemical anomalies, where surface soil samples returned assays of up to 0.15% Li2O (Refer ASX released dated 8 February 2023).

RC drill chips identified various pegmatite composition, with logged mineralogy including albite, microcline, quartz, muscovite, biotite, tourmaline, garnet, potential weathered spodumene, lithiophilite and tantalite. Additional mineralogical analysis, such as x-ray diffraction (XRD), is required to determine whether the mineralised lithium in the assay results is altered spodumene, or other lithium minerals[1] .
Notably, there are multiple haloes of elevated lithium returned within the greenstone sequence surrounding some of the pegmatites. These zones were always moderately sheared and often biotite altered mafic and ultramafic lithologies, often at the contact with a pegmatite intrusion.
Internal mineral zonation of the pegmatites was observed at shallow depths within 23RC026, which displayed elevated Li, Ta and Cs surrounding a 2m wide barren quartz core (Figure 5 ). This mineralised zone contains what appears to be highly altered spodumene and tantalite. There was little to no mica observed in this intercept, indicating the lithium mineralisation is not from lepidolite.

Figure 5 - Drill chips from 23RC026 (5-30m) showing highly fractionated pegmatite.
The ratio of potassium (K) over rubidium (Rb) can be used to determine fractionation of pegmatites – known as the K/Rb ratio. The lower the ratio, the more fractionated. A K/Rb ratio of less than 20 is considered highly fractionated, and likely to be LCT pegmatite. K/Rb ratios between 20 and 30 may also be significant indicator to proximity to fractionated pegmatites.
1The Company advises that the reported observation of lithium-bearing minerals occurrence is not an estimate of mineralisation or lithium grade. In relation to the disclosure of visual results, the Company cautions that visual observations or estimates of rock and mineral types or abundance should never be considered a proxy or substitute for a laboratory analysis. Assay results are required to determine the widths and grade of the visual observations in preliminary geological logging.

Figure 6 is a scatter plot of the pegmatite samples only, showing the K/Rb value versus the lithium oxide (Li2O) assay. This graph shows the fractionation of the pegmatite samples, with sample points increasing in fractionation to the right. The sample points in the top right of the graph are also elevated in lithium (+0.1% Li2O).
Further analysis of this data, along with other fractionation ratios will provide details on trends and will provide guidance for additional drilling.

Figure 6 - Scatterplot of Li2O over K/Rb assays from pegmatite drilling samples.
Drilling of the geochemical anomalies in the south of the project area was less successful, with most pegmatites displaying low fractionation and not returning anomalous geochemical results.
The best intercept from the southern area was 6m @ 0.14% Li2O (23RC044 from 30m), within quartz-albite pegmatite and altered/sheared ultramafic.

NEXT STEPS
-
Review and classify the pegmatites with respect to lithium potential, with the view to linking individual pegmatites across the drill lines.
-
Analysis of all drilling results to identify trends within the fractionation ratios, which will assist with further planned drill targeting.
-
Mineralogical analysis, such as x-ray diffraction (XRD), will be undertaken on some of the more significant intercepts to confirm mineralogy.
-
Further geological and structural mapping to the northwest of the main drilling area, where transported cover may be masking pegmatite extensions.

About Horse Rocks
Located 20km south of Coolgardie in Western Australia’s Eastern Goldfields, the Horse Rocks Lithium Project comprises a 23.8km[2 ] exploration licence (E15/1770), 8km west of Mineral Resources’ (ASX: MIN) Mt Marion Lithium Mine (51.4MT @ 1.45% Li2O).
The Horse Rocks Lithium Project lies within a folded portion of an isolated greenstone belt, within the Coolgardie Domain of the Yilgarn Craton. The greenstone belt is comprised of high-magnesium basalts, gabbroic sills and komatiite sequences. The granodiorite Depot Dome is to the immediate east of the greenstones and is the interpreted source of the many pegmatite intrusions within the tenure.
The Horse Rocks Lithium Project is considered prospective for pegmatite hosted lithium, nickel sulphide and orogenic gold mineralisation. Historical drilling has identified elevated nickel within the ultramafic sequences, along with gold anomalism in surface sampling. Large geochemical anomalies have been identified by Lord, and initial drilling has identified anomalous lithium within highly fractionated pegmatites.

APPENDIX 3 - JORC CODE TABLE 1
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 (e.g. 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 (e.g. ‘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 (e.g. submarine nodules) may warrant disclosure of detailed information. |
• Sampling completed by Lord Resources Ltd (LRD) is conducted using industry standard practice, blanks and CRM’s at regular intervals. The performance of QAQC is monitored on a batch-by-batch basis. • The sampling in this announcement has been carried out using reverse circulation (RC) drilling. • A total of 52 holes were drilled, for 4,223m (23RC001-23RC052), with depths ranging from 30m to 156m. • Drillholes were located using hand-held GPS. • Sampling was carried out under LRD protocols and QAQC procedures as per current industry practice. See further details below. • RC drilling was used to obtain 1m samples collected through a cyclone into buckets and placed on the ground as 1m samples, generally in rows of 20. • Sample quality was high with any sample loss or moisture recorded in the sample table. • A representative sample was split from the bulk 1m sample via a cone splitter and collected in a calico bag. • Composite samples were collected with a scoop to generate 3m composite samples. • The 2-3 kg composite samples were dispatched to ALS laboratories in Perth. These samples were sorted and dried by the assay laboratory and pulverised. • All samples have been submitted to the laboratory for analysis by 4- acid digest, with overlimits analysed with sodium peroxide fusion. |
| Drilling techniques |
Drill type (e.g. core, reverse circulation, open-hole hammer, rotary air blast, auger, Bangka, sonic, etc.) and details (e.g. 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.). _ |
• The drilling contractor was Drillwest, used a 4inch rod string and RC hammer. • Drillholes were drilled at either -60° or vertical, as listed in Appendix 1 above. |
| 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. |
• The majority of samples were dry with sample quality recorded in the sample table. • Sample recoveries were visually estimated and recorded in the sample table. • The drill cyclone and buckets were cleaned between rod changes and at the end of each hole, to minimise contamination. • At this stage, there is no observed relationship between recovery and grade in the drilling. |
13
| Criteria | JORC Code explanation | Commentary |
|---|---|---|
| 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 and percentage of the relevant intersections logged. |
• All holes were logged geologically by LRD geologists, using the companies logging scheme. • Logging is both qualitative and quantitative in nature. • Logging includes recording lithology, mineralogy, mineralisation, weathering, colour and any other identifiable features, for the entire drillhole. • A photograph taken of the drill chips for each drillhole. • All drillholes were logged in full. |
| 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. 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. |
• No core samples were collected. • Composite samples were collected with a scoop. • 1m individual samples were collected via a cone splitter directly from the cyclone. • Samples are recorded as dry, wet or damp. >90% of samples were dry with good recovery. • If anomalous results are returned from the composite sample, the single metre samples may be submitted for analysis. • Composite samples are not used in resources calculations. • Samples were prepared at the ALS geochemical laboratory in Perth. • Samples were dried, and the whole sample pulverised to 90% passing 75um, and a reference sub-sample of approximately 200g retained. • A nominal 0.25g was used for the analysis. This procedure is industry standard for this type of sample. • CRM’s were inserted at a ratio of approximately 1:20. • Samples are collected at 1m intervals or composited into 3 m samples using a scoop to sample individual metre samples. • Certified Reference Materials (CRM’s) and/or blanks are analysed with each batch of samples. These quality control results are reported along with the sample values in the final report. • Compositing of samples involves collection of representative scoops from within the single sample metre pile. Samples weigh 2-3kg prior to pulverisation. • Sample sizes are considered appropriate to give an indication of mineralisation given the particle sizes and the practical requirement to maintain manageable sample weights. |
| 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 (e.g. standards, blanks, duplicates, external laboratory checks) and whether acceptable levels of accuracy (i.e. lack of bias) and precision have been established. |
• Samples from holes 23RC001-007 and 23RC010-012 were analysed via sodium peroxide fusion (ME-ICP89), which is considered a full digest for ore-grade lithium and associated whole rock elements in hard rock lithium settings. • Samples from holes 23RC008-09 and 23RC013-052 were analysed via 4-acid digest (ME-MS61), which is considered a total digest for lithium. Any over limits for Ta, Cs or Be assayed via sodium peroxide fusion. This method is considered appropriate for first pass exploration • No geophysical tools were utilised. • Blanks or CRM’s for lithium were inserted approximately every 20 samples. Results were reviewed on a batch by batch basis, with all assays passing QC protocols, showing no levels of contamination or sample bias. • Both internal and external checks verified the validity of the sampling, preparation and assay results. |

| Criteria | JORC Code explanation | Commentary |
|---|---|---|
| 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 |
• Significant intersections were inspected and verified by senior company personnel • Twinned holes have not been drilled • Logging and sampling data were directly entered into the company digital logging software with drill and sample logs stored securely on the company’s server and cloud-based database. • The following adjustments have been made to the assay results to convert from elemental value to common oxide value: oLi to Li2O (x 2.1527) oCs to Cs2O (x 1.0602) oTa to Ta2O5(x 1.2211) • No other adjustments have been made to assay results. |
| 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. |
• The drillhole collar positions were surveyed using a handheld GPS. • Accuracy is generally in the range of +/- 5m for E/N and +/- 10m for RL. • No downhole surveys were completed. • The angle of the drill rig mast is set up using a clinometer and rig is orientated using a handheld compass. • All coordinates were recorded in GDA94 z51. • There has been no topographical control applied |
| 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 drill spacing is suitable for reporting of exploration results. • The drill spacing is not suitable for Mineral Resource estimation. • Sample compositing has not been applied. |
| 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. |
• Drilling has occurred at a near perpendicular angle to the targeted lithological unit. • The sampling is believed to be unbiased in regard to orientation of the geology. |
| Sample security |
The measures taken to ensure sample security. |
• Samples were submitted in pre -numbered plastic bags (five calico bags per single plastic bag), sealed and transported to the Laboratory in Perth for assaying. |
| Audits or reviews |
The results of any audits or reviews of sampling techniques and data. |
• Sampling and assaying techniques are industry standard. No specific audits or reviews have been undertaken at this stage in the program. • The results of this drill program have been reviewed by LRD senior management. |

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 |
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 Horse Rocks Lithium Project, consists of one Exploration Licence E15/1770, covering 23.8km2and is located approximately 20km south of Coolgardie, Western Australia. It is readily accessible from Coolgardie via the sealed Coolgardie-Esperance highway and thereafter northwards along the unsealed fence lines and historic drilling tracks. • The Project is within the Yallari Timber Reserve. A Conservation Management Plan (CMP) has been approved by the Environment Minister and is attached as a tenement condition. • E15/1770 is in good standing, and is held by Tailflower Pty Ltd, a wholly owned subsidiary of Lord Resources Ltd. |
| Exploration done by other parties |
Acknowledgment and appraisal of exploration by other parties. |
• The majority of past exploration work within the project area including drilling, surface sampling; geophysical surveys, geological mapping was largely completed in the 1970’s by Carpentaria Exploration, and 1990’s MPI and Newcrest. • The reports are available on the West Australian Mines Department WAMEX open file library. |
| Geology | Deposit type, geological setting and style of mineralisation. |
• The Project lies on the Coolgardie Domain, of the Kalgoorlie Terrain, within the Eastern Goldfields Supergroup, which is part of the Yilgarn Craton. The dominant geological feature of the tenure is an anticlinal folded portion of an isolated Archaean greenstone belt, between the Nepean-Coolgardie belt and the Saddle Hills-Spargoville belt. The greenstone unit has been metamorphosed to upper greenschist to mid-amphibolite facies. • The Depot Dome intrusion is located to the east of the tenure. The Depot Granodiorite is a medium- to coarse grained hornblende leucogranodiorite-tonalite, with moderate to strong shearing. This discrete granitoid dome is the interpreted source for pegmatites intrusions which host the Mt Marion Lithium Mine. Pegmatites have been historically mapped within the greenstone sequence, but the lithium potential has not been determined. • There are two east-north-easterly trending Proterozoic dykes bisecting the project area, the northern of which labelled the Celebration Dyke. • The north trending Kununalling Shear Zone passes through the Horse Rocks Project. The Ghost Crab – Mount Marion gold deposits are spatiallyassociated with shear zones. |
| Drillhole Information |
A summary of all information material to the understanding of the exploration results including a tabulation of the following information for all Material drillholes: easting and northing of the drillhole collar elevation or RL (elevation above sea level in metres) of the drillhole collar dip and azimuth of the hole down hole length and interception depth hole length. |
• An overview of the drill program is given within the text and tables of this announcement. • Holes drilled to date are listed in Appendix 1. |

| Criteria | JORC Code explanation | Commentary |
|---|---|---|
| Data aggregation methods |
In reporting Exploration Results, weighting averaging techniques, maximum and/or minimum grade truncations (e.g. 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. The assumptions used for any reporting of metal equivalent values should be clearly stated. |
• Assays are reported in Appendix 2 as down-hole length-weighted averages of grades. • No top-cuts have been applied. • The maximum lithium oxide value for each drillhole has been tabulated and depicted in the collar plan within the body of this document. • Where reported intercepts contain a narrower internal of higher-grade material, a sub-interval is reported and tabulated in the table. • No metal equivalent values are used. |
| Relationship between mineralisation widths and intercept lengths |
If the geometry of the mineralisation with respect to the drillhole 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 (e.g. ‘down hole _length, true width not known’). _ |
• Drillholes were oriented perpendicular (or near to) to lithological trends, where known. • Downhole lengths are reported and may not necessarily reflect true width. • No true widths are reported. |
| 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. |
• Refer to figures and tables in the body of this announcement. |
| 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. |
• The report has been prepared to summarise the material results of the drilling program. • Further drilling will be completed and reported on in due course. |
| Other substantive exploration data |
Other exploration data, if meaningful and material, should be reported including (but not limited to): geological observations; geophysical survey results; geochemical survey results; bulk samples – size and method of treatment; metallurgical test results; bulk density, groundwater, geotechnical and rock characteristics; potential deleterious or contaminating substances. |
• All material results from exploration at Horse Rocks have been disclosed in this announcement. |
| Further work | The nature and scale of planned further work (e.g. tests for lateral extensions or depth extensions or _large-scale step-out drilling). _ |
• Planned further exploration will consist of further assessment of the geochemical data, including assessing trends in fractionation ratios. This will determine follow up drilling. |
