-
GBAC035: 12m @ 4.8% halloysite, 77.4% Kaolinite from 30m
-
Approval to extend drilling to the north has been received from the SA Department of Energy and Mining, with additional work programs to infill and extend drilling to the south, east and west submitted, pending approvals
-
An aggressive follow up drill campaign has commenced planning and is anticipated to commence in March 2021, aimed at expanding the footprint of this emerging deposit
Oar Resources Limited ( ASX: OAR ) ( “OAR” or “the Company” ) is pleased to advise that results from its maiden air core program at the Company’s 100% owned Gibraltar Halloysite project (“ Gibraltar ” or “ the Project ”), on the Eyre Peninsula of South Australia ( SA ) have been now been received; with results confirming the presence of kaolinite in all holes sampled, and high-value halloysite in 24 of the 59 or 40% holes drilled ( Figure 1 ).
The high proportion of Halloysite samples within the program gives the Company encouragement it can improve on this very exciting initial discovery, given the location of the Gibraltar exploration tenement proximate to other known Halloysite mineralisation in the area ( Figure 3 ).
Detailed X-Ray Diffraction (“ XRD ”) and Scanning Electron Microscope (“ SEM ”) analysis of clay particles has shown high-grade halloysite, with grades up to 20% in one drill hole located at the end of a line of drilling, with no drilling to the west or south of this high-grade intersection. The Company believes it has identified a high-grade halloysite zone at which further drilling could improve the resource potential of this exciting discovery.

Similarly, an additional high-grade halloysite ( >10% ) zone has been identified in the last hole of a ‘scout’ line of drilling approximately 2 kilometres to the south ( Figure 2 ), where additional drilling will also be concentrated.
Significant composite results from the Gibraltar Project are presented in the table below ( Table 1 ), with a full list of drillhole collar details and sample analyses provided in Appendix 1.
The first phase drilling campaign was designed around a single halloysite occurrence in drilling noted from an historic report. Based on this single comment, the maiden drilling campaign, comprising 2,044 metres drilled was completed comprising a northern block of drilling on a nominal 100m x 100m grid pattern around the historic drill hole, widening out to 200m x 200m drill pattern to the south, and two ‘scout’ lines of drilling further to the south again ( Figure 1).
Having recently received final approvals from the South Australian Department of Energy and Mining, the Company now intends to commence an aggressive second drill campaign to extend the “halloysite zone” with sufficient results to be able to advance to a maiden resource calculation for the project. The Company is fully funded to complete this next phase drilling program and with a suitable drilling contractor already identified, drilling is anticipated to commence in March 2021.
The current area of drilling covers an area of just 5km[2] of the total 317km[2] area of the Gibraltar Project tenement EL6505 ( Figure 3 ), which provides the Company with the dominant land position in the region.
Logging of drill cuttings showed the development of a consistent layer of kaolinitic saprolite in the northern area, with several deeply incised channels containing lignite clays encountered on the scout lines to the south. Test work has confirmed strong kaolin development within the saprolite with over 85% kaolin detected in a number of samples[1] .
Detailed test work undertaken by the CSIRO, the University of SA and Bureau Veritas included size fraction analysis to determine the percentage of sample reporting to the -45 micron size fraction; XRF analysis to determine Fe2O3, Al2O3, Ti2O3 and SiO2 content; XRD and SEM to determine clay mineral species (halloysite and kaolinite), and reflectance analysis.
Results from the XRD and SEM analysis for the high-value halloysite mineral has highlighted specific ‘pods’ where halloysite has developed within the kaolinite material, with these pods remaining open in all directions ( Figure 2 ). Significant composite results from the Gibraltar Project are presented in the table below ( Table 1 ), with a full list of drillhole collar details and sample analyses provided in Appendix 1 .

Table 1 : Significant halloysite intersections[2] - Gibraltar Halloysite Project, South Australia
The test work results have confirmed very good percentage of kaolin in the -45um size fraction ( Table 3 ) . The XRF analysis has shown moderately high Fe2O3 content which has resulted in a discolouration of some of the kaolinite clays to a cream/ white colour. While this has no apparent detrimental effect on the high-value halloysite grades, the reflectance of the kaolinite is reduced as a result of this iron oxide staining, with the ISO-B value inversely proportional to the Fe2O3 content.
Clear spatial trends in the Fe2O3 distribution can be seen in the data from this initial drilling, indicating that the discolouration of the kaolinite may also be confined to distinct pods; suggesting that additional drilling may define areas of lower iron, and hence brighter kaolinite clays.
Halloysite is a rare derivative of Kaolinite that commands a significantly higher contract price in industrial applications. The Company will therefore focus its efforts on determining the Halloysite mineralisation component as a priority over the Kaolinite found at Gibraltar. Halloysite has potential in multiple applications which include controlled release drug delivery, carbon capture[3] , premium

Oar Resources GM of Exploration Mr Tony Greenaway commented : “These results from the maiden air core drilling program at our Gibraltar Project are extremely pleasing, having confirmed the presence of the high-value halloysite mineral within the kaolinitic saprolite. Our test work results are showing multiple pods within the kaolinite where halloysite is present. Our highest-grade result of 20% halloysite occurred in the last hole of a line of drilling, with no drilling to the west or south, leaving this high-grade pod completely open in those directions.”

“This drilling program was undertaken on the basis of a single comment noting halloysite in a historic report; the fact that we now have halloysite confirmed in 24 of the 59 holes drilled is an excellent result and gives the Company a high degree of confidence in the potential of the Gibraltar Project’. We will now look to extend out drilling to the north, south east and west with over the coming months. This new drilling campaign will be fast tracked to allow OAR to move into resource definition as quickly as possible”

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. • Whether a relationship exists between sample recovery andgrade and whether |
• 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. |

| 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 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. |
• 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 respresentatives • 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. Quantitative analysis of the XRD data was performed by CSIRO using SIROQUANT and Halloysite:Kaoliniteproportions |

| 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 Hunterlab QE instrument. |
||
| 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. |
• 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. |
| 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. |
• Sample and assay data from aircore drilling have been compiled and reviewed by the OAR GM Geology, who was involved in the logging and sampling of the drilling at the time. |
| 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. |
• Drill holes were located using a hand held GPS with +/- 5m accuracy • The grid system used is MGA94 Zone 53 for South Australia . |
| 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. |
• Aircore drilling has been completed on a 100m x 100m drill spacing over areas of previous drilling, and a nominal 200m x 200m drill spacing elsewhere. |

| • Whether sample compositing has 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 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. |
• At all times samples were in the custody and control of the Company’s representatives until delivery to the laboratory where samples were held in a secure enclosure pending processing. |

Section 2 Reporting of Exploration Results
(Criteria listed in the preceding section also apply to this section.)
| 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 Gibraltar Project is covered by a Granted Exploration Licence EL6506. • The EL is current and live |
| Exploration done by other parties |
• Acknowledgment and appraisal of exploration by other parties. |
• Shallow auger sampling has been completed over the Gibraltar Project area by Monax resources, with hole locations and assay results contained within company reports |
| Geology | • Deposit type, geological setting and style of mineralisation. |
• Kaolin occurrences, such as that seen on the Gibraltar Project, developed in situ by weathering of the feldspar-rich basement. • The resultant kaolin deposits are sub-horizontal zone of kaolinised granite resting with a sharp contact on unweathered basement. The kaolinised zone is overlain by loosely consolidated Tertiary and Quaternary sediment and silcrete. • Halloysite is a rare derivative of kaolin where the mineral occurs as nanotubes. The kaolin encountered at the Gibraltar Project contain variable amounts of naturally occurring halloysite within the kaolinite saprolite. |
| 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 odip and azimuth of the hole 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 detractfrom 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, groundwater,geotechnical and rock |
