ASX Announcement
FOLLOW-UP AND EXTENSIONAL AIR-CORE DRILLING COMMENCED, GIBRALTAR HALLOYSITE PROJECT,
SOUTH AUSTRALIA
HIGHLIGHTS:
-
Follow-up and extensional Air-Core drilling has commenced at the Company’s Gibraltar Halloysite-Kaolin project in South Australia.
-
Drilling will comprise an initial 2,500m of drilling on a 400m x 400m grid pattern to the north of previous drilling, where results returned high-grade halloysite (20%[1] ) in saprolitic clays.
-
Drilling will focus on extending the current zones of high-grade halloysite which remain open to the north, and identifying areas of more felsic basement lithologies.
-
Additional infill drilling on 200m spacing, contingent on initial observations from the wider spaced drilling, can be completed under the existing drilling approvals.
Oar Resources Limited ( ASX: OAR ) ( “OAR” or “the Company” ) is pleased to advise that air-core drilling has commenced at the Company’s Gibraltar project (“ Gibraltar ” or “ The Project ”), located on the South Australian Eyre Peninsular, to the north and adjacent to the Andromeda Metals Ltd ( ASX: ADN ) (“ Andromeda ”) Mt Hope kaolin - Halloysite Project ( Appendix 1 ).

The Company will complete an estimated 2,500m of shallow drilling in approximately 47 holes on a 400m x 400m grid pattern. Drilling will test an area extending some 3.5 kilometres to the north of the Company’s previously completed aircore drilling ( Figure 2 ), which successfully confirmed the presence of high-grade halloysite mineralisation (20%[1] ) within a blanket of saprolitic clays developed above a gneissic granite basement. The Company has the capacity within the existing approvals to extend the drilling campaign should it so wish, based on the initial in-field observations.

The high proportion of samples containing halloysite from the initial program[1] has given the Company encouragement it can expand on this very exciting initial discovery; with drilling also looking to identify areas of more felsic granite basement lithologies, which should result in the development of high brightness kaolinitic saprolitic material.
The Company has submitted applications for additional drilling to the south, west and east of the existing air-core drilling completed in late 2020 ( Figure 2 ), where it plans to undertake similar wide spaced extensional drilling where previous results show high-grade halloysite mineralisation; and regional scale reconnaissance drilling to better map-out the basement lithologies.
With the Eyre Peninsula covered with a layer of calcrete, the underlying geology is completely masked. Shallow, inexpensive air-core drilling is the best way to identify and understand the regional geology. The OAR geological team has been undertaking a regional scale interpretation of the basement lithologies, based on our own and historic drilling within the Eyre Peninsula, in order to prioritise exploration within the Company’s extensive tenement package ( Appendix 1 ).
Oar Resources GM of Exploration Mr Tony Greenaway commented : “We are excited to be back drilling at our Gibraltar Project to follow up on our initial success, which confirmed the presence of high-grade halloysite on the Project. Our initial drilling highlighted multiple halloysite pods within the kaolinite clays, with our highest-grade result of 20% halloysite occurring at the end of a line of drilling.”
“This current program is designed to significantly extend drilling to the north, where we are looking to both expand the known halloysite pods; and identify areas of more felsic basement material, which have a lower mafic component and should result in the development of a brighter white kaolinitic saprolite. With the Eyre Peninsula covered with a calcrete cap and very little to no outcropping basement, we must complete our systematic drilling to understand the underlying geology.”

APPENDIX 2
JORC Code, 2012 Edition – 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. |
• 2020 OAR: Aircore drilling consisted of vertical holes to industry standard completed by Oar Resource Ltd (“OAR”) generating individual 1m samples. A total of 59 holes for 2,043m were completed at the Gibraltar Project in late 2020. Sample compositing was carried out on site by OAR representative’s • Aircore 1m samples were composited based on perceived reflectance levels. Composite intervals range from 1-4m |
| 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). _ |
• OAR drilling is completed using industry standard practices. AC drilling is with a blade bit. • All drill collar positions are recorded using handheld GPS. |
| 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. |
• Air core drilling samples are not weighed, however smaller samples (on a relative basis) are noted in drill logs • No indication of sample bias with respect to recovery has been established. |
6
| Criteria | JORC Code explanation | Commentary |
|---|---|---|
| • 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. |
||
| 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. |
• OAR geological logging is completed for all holes and is representative across the ore body. The lithology, alteration, and characteristics of drill samples are logged on hard copy logs and entered into excel using standardised geological codes. • Logging is both qualitative and quantitative depending on field being logged. • All drill-holes are logged in full. |
| Sub-sampling techniques and sample preparation |
• If core, whether cut or sawn and whether quarter, half or all cores 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. |
• Spear sample compositing consisted of contiguous 1m drill samples up to 5m in total length, based on drill logs and visual estimation of whiteness of material. Sample composites were prepared with the aim of including kaolinised saprolite of similar quality within each composite, although in some cases narrow bands of discoloured kaolinised saprolite were included in the composite. • Composite Sample took place on site by OAR representatives • Samples were processed by laboratory Bureau Veritas. Sample weights were recorded before any sampling or drying. Samples are dried at low temperature (60C) to avoid destruction of halloysite. The dried sample was then pushed through a 5.6mm screen prior to splitting. • A small rotary splitter is used to split an 800g sample for sizing. • The 800g split is then wet sieved at 180µm and 45µm. The +180 and +45µm fractions are filtered and dried with standard papers then photographed. The -45µm fraction is filtered and dried with 2micron paper. • A small portion of the -45µm material is split for XRF analysis. • At CSIRO, Division of Land and Water, Urbrae, South Australia testing was conducted on selected -45µm samples by the method below. • The dried -45µm sample was analysed for quantitative elemental and mineralogical testing by XRD. A 2-gram subsample was micronised, slurried, spray dried, and a spherical agglomerated sample prepared for XRD. |

| Criteria | JORC Code explanation | Commentary |
|---|---|---|
| Quantitative analysis of the XRD data was performed by CSIRO using SIROQUANT and Halloysite: Kaolinite proportions determined using profile fitting by TOPAS, calibrated by SEM point counting of a suite of 20 standards. • ISO Brightness and Lab* colour of the dried - 45micron kaolin powder were determined according to TAPPI standard T 534 om-15 using by the University of South Australia, using a Hunter lab QE instrument. |

• The analytical method and procedure were as recommended by the laboratory for exploration and are appropriate at the time of undertaking. • As this is early-stage exploration with a wide variation in sample results the Company has not inserted field control samples in the regular stream of sampling. This is considered appropriate for early-stage exploration. The laboratory inserts a range of standard samples in the sample stream the results of which are reported to the Company. • The laboratory uses a series of control samples to calibrate the XRD and XRD instrumentation. Analytical work was completed by an independent analytical laboratory. • A number of samples are selected as part of the Company’s routine QA/QC process and dispatched for independent SEM analysis for visually verification of clay mineral species. |

• 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 mineralized structures is considered to have introduced a sampling bias, this should be assessed and reported if material. |
• Sampling is preferentially across the strike or trend of mineralized outcrops |
| Sample security |
• The measures taken to ensure sample security. |

• Not Applicable - No new drill results are being reported in this announcement. |
10
| Criteria | JORC Code explanation | Commentary |
|---|---|---|
| exclusion does not detract from the understanding of the report, the Competent Person should clearly explain why this is the case. |
||
| 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. |
• Reported summary intercepts are weighted averages based on length. • All samples were selected for XRD analysis at CSIRO • No maximum or minimum grade truncations have been applied. • No metal equivalent values have been quoted. |
| 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 (e.g. ‘down _hole length, true width not known’). _ |
• Drillhole angle relative to mineralisation has been almost perpendicular, with vertical drillholes through flat horizontal mineralisation related to the regolith. Generally, the strata- bound intercepts are close to true width |
| 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 maps and tabulations are presented in the body of 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 avoiding misleading reporting of Exploration Results. |
• Comprehensive results are reported in the body of the announcement as tabulated in Appendix 1. |
| 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, _ |
