Hurley & Crean - Large, depth extensive, mineralised carbonatites
-
Assays from first pass RC drilling at Hurley have confirmed another large niobium-REE mineralised carbonatite at the Aileron project (100% ENR) in the West Arunta region of WA
-
Extensive mineralisation intersected on all four drill lines at Hurley, over 1km in strike, including:
-
24m @ 0.93% Nb2O5 & 0.24% TREO from 66m (EAL034) part of 74m @ 0.53% Nb 2 O 5 & 0.20% TREO from 64m
-
28m @ 0.68 % Nb2O5 & 0.16% TREO from 210m (EAL115) part of 165m @ 0.36% Nb 2 O 5 & 0.15% TREO from 90m to end of hole
-
72m @ 0.45% Nb2O5 & 0.14% TREO from 82m (EAL118) to end of hole
-
New results from RC drilling at Crean have extended the mineralised carbonatite including:
-
6m @ 1.10% Nb2O5 & 0.56% TREO from 72m and
-
2m @ 1.03% Nb2O5 & 0.11% TREO from 188m to end of hole (EAL018)
-
Latest assay results confirm four mineralised carbonatites were identified in the 2023 Aileron reconnaissance drill program
-
A large program of aircore/RC drilling (~20,000m) and diamond drilling is planned for 2024. Drilling aims to quantify the grade distribution and scale of these carbonatites and will also test several new, outstanding targets
-
Further details of the 2024 Aileron exploration campaign to be provided next month ahead of commencement
Commenting on the RC drilling at Aileron, Encounter Managing Director Will Robinson said: “First pass drilling at Hurley has identified another large, mineralised carbonatite, over 1km in strike, with every hole that penetrated the transported cover intersecting carbonatite.
In 2023, niobium-REE mineralised carbonatites were intersected at four separate prospects at Aileron in broad spaced drilling: Crean, Hurley, Emily and Green. Associated near surface, enriched niobium-REE mineralisation has been intersected in the initial drilling at two of the four prospects to date; Crean (up to 4m @ 3.8% Nb2O5 from 56m) and Emily (up to 12m @ 2.3% Nb2O5 from 54m).[1,2]
Drilling in 2024 will aim to quantify the scale and near surface potential of the four niobium-REE mineralised carbonatites identified so far.
In parallel, a diamond drill rig will commence initial testing of the large-scale geophysical targets identified in the eastern part of Aileron.”

Encounter Resources Ltd (“Encounter”) is pleased to report RC assay results from the Hurley and Crean carbonatites at the Aileron project (100% ENR), in the West Arunta region of WA.
Background
The 100% owned Aileron project covers 1,765km[2] and is located in the West Arunta region of WA, ~600km west of Alice Springs. The West Arunta is an emerging critical minerals province with significant niobium and REE discoveries made during 2023. Encounter completed large gravity, magnetic and radiometric surveys at Aileron and has used these baseline datasets to define initial drill targets within the project. To date Encounter has completed limited, wide-spaced first pass drilling in the western side of the project. Prospective targets identified in the central and eastern parts of the +100km wide project are still unexplored (Figure 2).

RC Drill Program
Hurley
The RC drilling at Hurley was designed to test an elongated gravity feature, coincident with a magnetic anomaly, situated on a major regional structure in the northern part of Aileron.
Nine effective RC holes were completed in the first pass drilling at Hurley with a further five holes terminated in transported cover. First pass drilling at Hurley intersected a depth extensive niobiumREE mineralised carbonatite over 1km in strike with intersections including:
-
24m @ 0.93% Nb2O5 & 0.24% TREO from 66m (EAL034) part of 74m @ 0.53% Nb 2 O 5 & 0.19% TREO from 64m
-
28m @ 0.68 % Nb2O5 & 0.16% TREO from 210m (EAL115) part of 165m @ 0.36% Nb 2 O 5 & 0.15% TREO from 90m to end of hole
-
72m @ 0.45% Nb2O5 & 0.14% TREO from 82m (EAL118) to end of hole
All the effective drill holes completed to date at Hurley, that penetrated the transported cover, have intersected the carbonatite. The niobium-REE mineralisation at Hurley appears to be stronger in the central and eastern drill lines where the system remains open to the north, south and east.
Crean
The first diamond drillhole at Crean (EAL007) intersected a niobium-REE mineralised carbonatite (previously reported):
-
19m @ 1.0% Nb2O5 & 0.2% TREO from 65m and
-
48m @ 1.0% Nb2O5 & 0.2% TREO from 181.5m (EAL007) part of 282m @ 0.54% Nb 2 O 5 & 0.17% TREO from 64m to end of hole

==> picture [116 x 24] intentionally omitted <==
RC drilling completed at Crean 200m north of EAL007 intersected mineralised carbonatite that extended to end of hole:
-
6m @ 1.10% Nb2O5 & 0.56% TREO from 72m and
-
2m @ 1.03% Nb2O5 & 0.11% TREO from 188m to end of hole (EAL018)
RC hole EAL019B drilled 200m south of EAL007 also intersected mineralised carbonatite but with less consistent niobium-REE mineralisation. Drilling further south (EAL020) did not penetrate the transported cover sequence, hence the southern margin of the carbonatite is not yet defined (Figure 3).
A broad spaced east-west line of 3 RC holes, 400m spaced (EAL091, 92 and 93) was completed at Crean, between EAL007 and EAL008. EAL091 and EAL092 intersected fenite alteration that is seen on the margins of carbonatites. EAL093 (drilled 220m west of EAL007) drilled through fenite alteration and into mineralised carbonatite to end of hole.
Further drilling in 2024 will aim to define the margins and orientation of the large and depth extensive carbonatite identified at Crean and to locate additional near surface, enriched mineralisation.

Next Steps
Hurley
Further RC and diamond drilling will be completed in 2024 to determine the scale and orientation of the Hurley carbonatite, identify the extent of the better zones of mineralisation within the carbonatite and locate possible associated near surface, enriched mineralisation.
Crean
Further drilling will be completed at Crean in 2024 with the aim of identifying further zones of high grade +1% Nb2O5 primary niobium-REE mineralisation and also test for zones of adjacent near surface, enriched mineralisation.
An initial metallurgical assessment of the large body of mineralisation at Crean has commenced with a mineralogical characterisation report from EAL007 expected in February 2024.

SECTION 1 SAMPLING TECHNIQUES AND DATA
| 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 sounds, or handheld XRF instruments, etc). These examples should not be taken as limiting the broad meaning of sampling. RC samples undergo routine 2 metre composite pXRF analysis using a Bruker S1 TITAN to aid in logging and identifying zones of interest. |
| Include reference to measures taken to ensure sample representivity and the appropriate calibration of any measurement tools or systems used Drill hole collar locations were recorded by handheld GPS, which has an estimated accuracy of +/- 5m. |
|
| 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 RC drilling was used to obtain riffle split 2m sample with each sample weighing approximately 3kg. |
|
| 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). Reverse circulation drilling was used in the drillholes to obtain 1-3 kg samples every 2m downhole. |
| Drill sample recovery |
Method of recording and assessing core and chip sample recoveries and results assessed RC sample recoveries were estimated as a percentage and recorded by Encounter field staff. |
| Measures taken to maximise sample recovery and ensure representative nature of the samples Driller’s used appropriate measures to minimise down-hole and/or cross – hole contamination in RC drilling. Where contamination of the sample was suspected this was noted by Encounter field staff as a percentage. |
|
| 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. To date, no detailed analysis to determine the relationship between sample recovery and/or and grade has been undertaken for this drill program. |
8
==> picture [116 x 24] intentionally omitted <==
| 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. Encounter Geologists complete geological logs on all RC chips. Lithology, alteration, mineralisation, structure and veining are recorded. Detailed logging of diamond holes is completed by Encounter Geologists |
| Whether logging is qualitative or quantitative in nature. Core (or costean, channel, etc) photography. Geological logging is qualitative in nature and will record interpreted lithology, alteration, mineralisation, structure, veining and other features of the samples. |
|
| The total length and percentage of the relevant intersections logged Encounter Geologists have logged reported drillholes in full including lithology, alteration, mineralisation, structure and veining. |
|
| Sub-sampling techniques and sample preparation |
If core, whether cut or sawn and whether quarter, half or all core taken. No diamond drillholes are being reported |
| If non-core, whether riffled, tube sampled, rotary split, etc and whether sampled wet or dry. RC samples were collected on the rig using a riffle splitter. Samples were recorded as being dry, moist or wet by Encounter field staff. |
|
| For all sample types, the nature, quality and appropriateness of the sample preparation technique. Samples will be sent to ALS laboratories in Perth for analyses. Samples will be crushed and pulverised to enable a subsample for analyses. This is considered appropriate for the analysis to be undertaken. |
|
| Quality control procedures adopted for all sub-sampling stages to maximise representivity of samples. Field QC procedures involve the use of commercial certified reference materials (CRMs) and in house blanks. The insertion rate of these is at an average of 1:33. |
|
| 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. Field duplicates were taken during RC drilling and were collected on the rig via a riffle splitter at a rate of 1:50. The results from these duplicates are assessed on a periodical basis. |
|
| Whether sample sizes are appropriate to the grain size of the material being sampled. The sample sizes are considered appropriate to give an accurate indication of the mineralisation. |
|
| 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. All samples were submitted to ALS Laboratories in Perth for analysis. Assays have been reported from ALS method ME-MS81D (ME- MS81D reports high grade REE elements by lithium meta-borate fusion and ICP-MS. This method is considered a complete digestion allowing resistive mineral phases to be liberated. This method produces quantitative results of all elements, including those encapsulated in resistive minerals.) Samples were analysed for Ba, Ce Cr, Cs, Dy, Er, Eu, Ga, Gd, Hf, Ho, La, Lu, Nb, Nd, Pr, Sc, Sm, Sn, Sr, Ta, Tb, Th, Ti, Tm, U, V, W, Y, Yb, Zr, SiO2, Al2O3, Fe2O3, CaO, MgO, Na2O, K2O, Cr2O3, TiO2, MnO, P2O5, SrO, BaO. Niobium overlimit determination was completed via ALS method ME- XRF30. Assays have been reported from ME-XRF30 when completed. Standard laboratory QAQC was undertaken and monitored. |

| Data spacing and distribution |
Data spacing for reporting of Exploration Results. Crean - RC drill hole spacing is 200m on north-south oriented drill lines. A single east-west line (3 holes, 400m spaced) was completed between two north-south sections 1.5km apart. Regional – north-south line of drilling was completed at 400m spacing. Hurley – four north-south drill sections were completed spaced 200- 400m apart with 1-3 effective holes per drill section. A single north-south drill line was completed at the Wild target at 200m spacing. |
|---|---|
| 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. Mineralisation has not yet demonstrated to be sufficient in both geological and grade continuity appropriate for the Mineral Resource and Ore Reserve estimation procedure(s) and classifications to be applied. |
|
| Whether sample compositing has been applied. Intervals have been composited using a length weighted methodology. |
|
| 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. This is early-stage exploration drilling and the orientation of the hole with respect to key structures is not fully understood. |
| 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. This is early stage drilling and the orientation of the hole with respect to key structures is not fully understood. |
|
| Sample security | The measures taken to ensure sample security. The chain of custody is managed by Encounter. Samples will be transported by Encounter personnel and reputable freight contractors to the assay laboratory. |
| Audits or reviews | The results of any audits or reviews of sampling techniques and data. Sampling techniques and procedures are regularly reviewed internally, as is data. To date, no external audits have been completed on Aileron data. |

| Data aggregation methods Relationship between mineralization widths and intercept lengths |
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. All reported assays have been length weighted, with a nominal 0.1% Nb2O5and 0.5% TREO lower limit and a maximum of 4m of internal dilution. Intervals greater than 1% Nb2O5have been reported separately. No upper cuts-offs have been applied. |
| Where aggregated 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. All reported assays have been length weighted, with a nominal 0.1% Nb2O5and 0.5% TREO lower limit and a maximum of 4m of internal dilution. Intervals greater than 1% Nb2O5have been reported separately. No upper cuts-offs have been applied. |
|
| The assumptions used for any reporting of metal equivalent values should be clearly stated. No metal equivalents have been reported in this announcement. |
|
| These relationships are particularly important in the reporting of exploration results. If the geometry of the mineralization 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’). The geometry of the mineralisation is not yet known due to insufficient drilling in the targeted area. |

| Diagrams Balanced Reporting Other substantive exploration data Further Work |
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 plane view of drill hole collar locations and appropriate sectional views. Refer to body of this announcement |
|---|---|
| Where comprehensive reporting of all Exploration Results is not practical, representative reporting of both low and high grades and/or widths should be practiced to avoid misleading reporting of Exploration Results. All reported assays have been length weighted, with a nominal 0.1% Nb2O5and 0.5% TREO lower limit and a maximum of 4m of internal dilution. Intervals greater than 1% Nb2O5have been reported separately. No upper cuts-offs have been applied. |
|
| Other exploration data, if meaningful and material, should be reported including (but not limited to): geological observation; 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 meaningful and material information has been included in the body of the text. No metallurgical assessments have been completed. |

| The nature and scale of planned further work (e.g. 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. The next phase of work will include further aircore/RC/diamond drilling at Hurley and Crean. |
