Red Dirt Metals Limited (ASX: RDT) (“ Red Dirt ” or the “ Company ”) is pleased to announce an update for its wholly owned Mt Ida Lithium Project (“ Mt Ida ”) in the Eastern Goldfields region of Western Australia. As announced on 19 October 2022, Mt Ida has an initial global resource base of 12.7Mt @ 1.2% Li2O and the Company is advancing the expansion and upgrade as well as further development of this resource base.
Excellent drilling intercepts starting at 30 metres below surface and extending to deeper levels within the Sister Sam and Timoni Lithium deposits (Table 1), demonstrate the calibre of the Mt Ida Lithium Project. Mineralisation remains open at depth and the results in this announcement relate to 27 holes and 4,392 metres drilled in January and February 2023.
Commenting on the results Executive Chairman, David Flanagan said;
“It is all about speed to market. We have a granted mining lease with a long and recent history of mining, proximity to infrastructure in Western Australia, arguably the world’s best mining jurisdiction, 5 rigs in the field, thousands of samples in the lab and targeting approval to start mining this year. The outlook for lithium is fantastic and with so many high grade and wide drill intercepts we see strong prospects for material resource extensions.”

The Company continues to advance infill, extension and exploration RC and DD drilling programs across the Mt Ida Lithium Project. More than 6,000 Mt Ida samples are currently with the labs undergoing analysis with results expected to arrive in batches over the next 6-12 weeks. Further planned drill programs will cover more than 200 holes and 60,000 metres through the balance of 2023. Four priority Air Core (AC) anomalies have been identified and regional AC drilling designed to detect low tenor “host rock hanging wall” lithium anomalism. These are currently being followed up by RC drill testing with an initial 20 holes for 3,450 metres. The table below summarises intercepts better than 3.5 metres at 0.7% Li2O.

Results from drilling
Shallow Infill and extension resource drilling has been successful in outlining continuous mineralisation in the top 100 metres of the orebodies at Sister Sam and Timoni pegmatites. Weathering is variable but in general the pegmatites are weathered down to 30-50 metres. Below the weathering zone continuous Lithium mineralisation is present. This updated drilling data is being used to optimise conceptual open pit and underground (Figure 3) mining scenarios and underpin studies moving forward in turn. This work has greatly assisted in defining the “economic centres of mineralisation” as key targets for drilling and ultimately increasing the resource classification.
As well as the shallow near surface drilling results some deeper intercepts have been returned from Sister Sam demonstrating the exceptional nature of the ore body below 100 metres vertical depth. Assays continue to confirm thick (>30 metre true thickness) continuous high grade Lithium mineralisation (Figure 2).
Limited step out exploration drilling around Sister Sam, Timoni and the GAP has been completed over recent months with eagerly anticipated results due in coming weeks. Results of this limited drilling will further test adjacent resource expansion potential (Figure 3, Figure 4).

Table 1; Section 1: Sampling Techniques and Data
| Criteria | 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 |
• Sampling activities carried out by Red Dirt Metals at the Mt Ida Project have included reverse circulation (RC), air core (AC) and diamond (DD) drilling, and rock chip sampling. Core sampling of one historic drillhole has also been carried out, with assaying, petrological and XRD analysis completed • RC samples were collected from a static cone splitter mounted directly below the cyclone on the rig, AC samples were collected using a spear from piles on the ground into 2m composites or 1m bottom of hole samples, DD sampling was carried out to lithological/alteration domain with lengths between 0.3-1.1m • Limited historical data has been supplied, historic sampling referenced has been carried out by Hammill Resources, International Goldfields, La Mancha Resources, Eastern Goldfields and Ora Banda Mining, and has included rock chip sampling, and RC, DD and rotary air blast (RAB) drilling • Sampling of historic RC has been carried out via riffle split for 1m sampling, and scoop or spear sampling for 4m composites, historic RAB drilling was sampled via spear into 4m composites • Historic core has been cut and sampled to geological intervals • These methods of sampling are considered to be appropriate for this style of exploration |
| Drilling techniques |

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. |
• DD sampling is undertaken by lithological/alteration domain to a maximum of 1.1m and a minimum of 0.3m. Core is cut in half with one half sent to the lab and one half retained in the core tray • Occasional wet RC samples were encountered, extra cleaning of the splitter was carried out afterward • RC, DD and AC chip samples have been analysed for Li suite elements via ICPMS, and for Au by 50g fire assay by ALS, Nagrom, NAL and SGS • Samples analysed by ALS, Nagrom, NAL and SGS were dried, crushed and pulverised to 80% passing 75 microns before undergoing a selected peroxide fusion digest or 4 acid digest with ICPMS finish or fire assay with ICPMS finish • Historic core sampled by Red Dirt Metals was collected for ICPMS analysis via selection from NQ half and quarter core, and submitted to Nagrom • Semi-Quantitative XRD analysis was carried out by Microanalysis Australia using a representative sub-sample that was lightly ground such that 90% was passing 20 µm to eliminate preferred orientation • RC and AC duplicate field samples were carried out at a rate of 1:20 and were sampled directly from the splitter on the rig. These were submitted for the same assay process as the primary samples and the laboratory are unaware of such submissions • Historic chip sampling methods include single metre riffle split and 4m composites that were either scoop or spear sampled, while historic core was cut onsite and half core sampled • Historic samples were analysed at LLAS, Genalysis and unspecified laboratories • Historic Au analysis techniques generally included crushing, splitting if required, and pulverisation, with aqua regia or fire assay with AAS finish used to determine concentration • Historic multielement analysis was carried with mixed acid digest and ICP-MS determination |

Acknowledgment and appraisal of exploration by other parties. |
• The area has a long history of gold and base metals exploration and mining, with gold being discovered in the district in the 1890s. Numerous generations of exploration have been completed including activities such as drilling, geophysics and geochemical sampling • Targeted Li assaying was first carried out in the early 2000s by La Mancha Resources and more recently, lithium assays were completed byOra Banda Mining |
| Geology | Deposit type, geological setting and style of mineralisation. |
• The Mt Ida project is located within the Eastern Goldfields region of Western Australia within the Mt Ida/Ularring greenstone belt • Locally the Kurrajong Antiform dominates the regional structure at Mount Ida, a south- southeast trending, tight isoclinal fold that plunges at a low angle to the south. The Antiform is comprised of a layered greenstone sequence of mafic and ultramafic rocks • Late stage granitoids and pegmatites intrude the sequence |
| 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: easting and northing of the drill hole collar elevation or RL (Reduced Level – elevation above sea level in metres) of the drill hole collar dip and azimuth of the hole down hole length and interception depth hole 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. |
• A list of the drill hole coordinates, orientations and metrics are provided as an appended table |
| 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. The assumptions used for any reporting of metal equivalent values should be clearly stated. |
• No metal equivalents are used • Significant intercepts are calculated with a cut-off grade of 0.3% Li2O |

| 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’). |
• The geometry of the mineralisation is roughly perpendicular to the drilling. |
| 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. |
• Figures are included in the 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. |
• All drill collars, and significant intercepts have been reported in the appendix |
| 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. |
• None completed at this time |
| Further work | The nature and scale of planned further work (eg tests for lateral extensions or depth extensions or large-scale step-out drilling). Diagrams clearly highlighting the areas of possible extensions, including the main geological interpretations and future drilling areas, provided this information is not commercially sensitive. |
• Drilling is continuing at Mt Ida with a 60,000m program consisting of a mix of RC diamond and AC drilling underway |
