ASX Announcement 28 January 2021
IOCG Style Copper-Gold-Rare Earths Signature at Aileron JV
-
IOCG style metal anomalism intersected in the partially completed drill hole (EAL001) at the Aileron copper-gold project (“Aileron”) part of a joint venture with Newcrest Mining Ltd (“Newcrest”) (ASX:NCM) located in the West Arunta region of WA.
-
Following mechanical issues with the drill rig, a decision was made in October 2020 to demobilise the rig and assay the completed section of the drill hole to 158m.
-
First drill hole into an unexplored belt contains hydrothermal hematite-altered mafic intrusions and granite with a distinctive IOCG geochemical signature under shallow cover (10m).
-
Assays include zones of anomalism in copper (up to 0.1% Cu), gold (up to 48ppb Au) and molybdenum (up to 155ppm Mo). Furthermore, highly elevated rare earth elements consistent with the targeted IOCG deposit model were identified including lanthanum (La) up to 0.2% and cerium (Ce) up to 0.3%.
-
In addition, as a result of the shallow cover depth established by drill hole EAL001, a line of orientation ground geochemistry (20 samples) was completed and successfully demonstrated contrast to background in gold.
-
IOCG mineralisation often has a strong density contrast to background and may be identifiable through the application of gravity surveys. This potentially provides a clear pathway to define drill targets in the prospect area.
-
Following evaluation of applicable gravity methods and surface geochemical sampling, future work programs for Aileron will be designed.
The directors of Encounter Resources Ltd (“Encounter / the Company”) are pleased to provide results from the partially completed drill hole at Aileron.
Commenting on the drilling at Aileron, Encounter Managing Director Will Robinson said:
“The partially completed hole, the first drill hole drilled into a remote and unexplored 70km long belt, has intersected zones of intense hydrothermal hematite alteration of the mafic intrusive and granite adjacent to the targeted magnetic anomaly. We are pleased to report that the hematite altered zones in the hole have a distinctive IOCG signature in a suite of elements including copper, gold, molybdenum and highly elevated rare earth elements. Of particular interest is the strong enrichment of the same two rare earth elements, lanthanum and cerium, that are similarly elevated in the Olympic Dam deposit.
This is a great start for us at Aileron. We have identified the key ingredients of an IOCG deposit model at an easily explorable depth in a highly prospective and unexplored copper-gold province.”

Background
Aileron is located in the West Arunta region of WA, ~600km west of Alice Springs. The project contains a number of structural targets identified through aerial magnetic surveys and the initial drill hole, EAL001 targeted a discrete magnetic anomaly (Figure 1).
There has been no previous mineral exploration at Aileron and EAL001 is the first drill hole into an unexplored belt which is prospective for large scale gold-copper deposits.
Diamond Drilling
Diamond drilling commenced in October 2020 to test a discrete magnetic anomaly. However, following mechanical issues with the drill rig, a decision was made to demobilise the rig and assay the completed section of the hole to 158m.
Significant initial observations from the drill hole include:
-
Shallow cover depth (10m) – opening up potential for application of surface sampling and shallow geochemical drilling.
-
Hydrothermal hematite-altered mafic intrusions and granite consistent with the IOCG model (see Photo 1).
-
Magnetite bearing banded iron formation (BIF) intersected at ~150m with high magnetic susceptibility consistent with the modelled anomaly. The centre of the magnetic anomaly was modelled to be intersected at ~300m downhole.
Assay results from the completed section have been received. The zones of hydrothermal hematite alteration, in particular the zone around 90-100m downhole (see Photo 1), have a distinctive IOCG geochemical signature.
Assays from the partially completed hole include zones of anomalism in copper (up to 0.1% Cu), gold (up to 48ppb Au), molybdenum (up to 155ppm Mo) and highly elevated rare earth elements (lanthanum up to 0.2%, cerium up to 0.3%), consistent with the targeted IOCG deposit model (see Figure 2).
The metal anomalism in the hole is associated with the most intense hematite altered zones (up to 15% Fe). Larger-scale mineralisation of this type should have a strong density contrast to background and be identifiable through the application of gravity surveys. This suggests potentially a clear pathway to defining additional high-quality, non-magnetic targets in the prospect area.
In addition, given the shallow cover depth, a line of orientation ground geochemistry (20 samples) was completed over the magnetic anomaly to assess amenability of surface sampling. Assay results from the -53 micron size fraction demonstrated contrast to background in gold. Accordingly, further assessment of surface geochemical methods at Aileron is required.
Next Steps
Following evaluation of the drill hole assay data, completion of petrography to establish the copper mineral species, evaluation of applicable gravity methods and further assessment of the amenability of surface geochemical sampling, future work programs for Aileron will be designed.

About Encounter
Encounter Resources Limited is one of the most productive project generation and active mineral exploration companies listed on the Australian Securities Exchange. Encounter’s primary focus is on discovering major gold and copper deposits in Australia.
Encounter controls a major land position the Tanami region of WA covering over 100km of strike along a major structural corridor. The company is advancing the Aileron project in the West Arunta via joint venture with Australia’s largest gold miner, Newcrest Mining Limited (ASX:NCM).
Complementing its expansive gold portfolio, Encounter controls a major ground position in the emerging Paterson Province where it is exploring for copper-cobalt deposits with highly successful mining and exploration company IGO Limited (ASX:IGO) and for copper-gold deposits at its 100% owned Lamil Project.
In addition, utilising new Geoscience Australia datasets, Encounter moved early and aggressively to secure a series of camp scale, first mover opportunities in the Northern Territory (“NT”) based on their potential to contain large, sedimentary-hosted and IOCG style copper deposits. This includes the Elliott copper project which is being advanced in partnership with BHP via an option agreement to enter an earn-in and joint venture.

| 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. The Aileron project was sampled by Encounter using diamond drilling. A single hole program was completed to a total depth of 157.8m of diamond drilling. The diamond hole was designed to test a discrete high amplitude magnetic anomaly defined in regional aeromagnetics |
| Include reference to measures taken to ensure sample representivity and the appropriate calibration of any measurement tools or systems used Drill hole collar location was 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 Diamond drill core samples were half core samples of PQ and HQ sized core. The samples from the drilling were sent to Bureau Veritas Minerals Pty Ltd Laboratories in Perth, where they were dried, crushed, pulverised and split to produce a sub – sample for Fire Assay, ICP – OES and ICP – MS analysis. |
|
| 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 hole was PQ rough cored to a depth of 13m then HQ cored to the EOH. Diamond drill core is orientated using a Reflex ACT3 tool. |
| Drill sample recovery |
Method of recording and assessing core and chip sample recoveries and results assessed Sections of lost core were minimal and were noted by the diamond drillers and shown on Table 2 in the announcement. |
| Measures taken to maximise sample recovery and ensure representative nature of the samples Drilling of the cover and clay saprolite was rough cored to provide some sample with recovery approximately 75% with the remainder of the holes being drilled conventional with core recovery +95%. |
|
| 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. |

|---|---|
| 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. Geological logging has been completed with lithology, alteration, mineralisation, structure and veining recorded. |
| Whether logging is qualitative or quantitative in nature. Core (or costean, channel, etc) photography. Geological logging is qualitative in nature and records interpreted lithology, alteration, mineralisation, structure, veining and other features of the samples and core. |
|
| The total length and percentage of the relevant intersections logged Core was logged in full by Encounter geologists. |
|
| Sub-sampling techniques and sample preparation |
If core, whether cut or sawn and whether quarter, half or all core taken. Samples submitted from the diamond drill holes were half core |
| If non-core, whether riffled, tube sampled, rotary split, etc and whether sampled wet or dry. Not applicable as all drilling was core drilling |
|
| For all sample types, the nature, quality and appropriateness of the sample preparation technique. Sample preparation was completed at Bureau Veritas Minerals Pty Ltd Laboratories in Perth. Samples were dried, crushed, pulverised (90% passing at a ≤75µM size fraction) and split into a sub – sample that was analysed using fire assay, ICP – OES and ICP – MS analysis. |
|
| 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 will be 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. No sampling of the second half of the drill core has been completed. |
|
| 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 at Aileron |
|
| 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. The sample(s) for ICP analysis have been digested and refluxed with a mixture of acids including Hydrofluoric, Nitric, Hydrochloric and Perchloric Acids. This extended digest approaches a Total digest for many elements however some refractory minerals are not completely attacked. Analytical methods used will be ICP – OES (Cu, Fe, K, Mg, Mn, Ni, P, S, Sc, Ti and Zn) and ICP – MS (Ag, As, Bi, Co, Mo, Pb, Sb, Sn, Te, W and Zr). Au, Pt and Pd were determined via Fire Assay. |
| 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. Not applicable as no geophysical instruments were use in determining these results |
|
| 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. Laboratory QAQC involves the use of internal lab standards using certified reference material, blanks, splits and replicates as part of in house procedures. |

|---|---|
| Verification of sampling and assaying |
The verification of significant intersections by either independent or alternative company personnel. Results included in this report have been verified by Sarah James (Senior Exploration Geologist) |
| The use of twinned holes. No twinned holes have been drilled. |
|
| Documentation of primary data, data entry procedures, data verification, data storage (physical and electronic) protocols. Primary data is on toughbook computers using Excel templates and Maxwell Geoservice’s LogChief software. Data collected was sent offsite to Encounter’s Database (Datashed software), which is backed up daily. |
|
| Discuss any adjustment to assay data. No adjustments, no assay data |
|
| 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. Drill hole collar locations are determined using a handheld GPS. Down hole surveys were collected during this drilling program at approx. 30m intervals downhole. |
| Specification of the grid system used. The grid system used is MGA_GDA94, zone 52. |
|
| Quality and adequacy of topographic control. Estimated RLs were assigned during drilling using hand held GPS and are to be corrected at a later stage using a DTM created during the aeromagnetic survey. |
|
| Data spacing and distribution | Data spacing for reporting of Exploration Results. A single diamond drill hole was drilled to a downhole depth of 157.8m |
| 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. N/A – this is early stage drilling and the orientation of sampling to the mineralisation is not known. |
| 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 sampling to the mineralisation is not known. |
|
| Sample security | The measures taken to ensure sample security. The chain of custody is managed by Encounter. Samples were delivered by XM Logistics personnel to RGR yard in Port Hedland and transported to Bureau Veritas in Canning Vale. |
| 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. |

| Mineral tenement and land tenure status |
Type, reference name/number, location and ownership including agreements or material issues with third parties including joint ventures, partnerships, overriding royalties, native title interests, historical sites, wilderness or national park and environmental settings. The Aileron project is located within the tenement E80/5169 which is held 50% by Encounter subsidiary Hamelin Resources Pty Ltd and 50% Newcrest Mining Ltd. This tenement is contained completely within Aboriginal Reserve land where native title rights are held by the Parna Ngururrpa. No historical or environmentally sensitive sites have been identified in the area of work. |
| Exploration done by other parties |
Acknowledgment and appraisal of exploration by other parties. No previous exploration has been conducted on the tenement other than government pre competitive data. |
| Geology | Deposit type, geological setting and style of mineralisation The Aileron project is situated in the Proterozoic West Arunta Province of Western Australia. The geology of the area is poorly understood do to the lack of outcrop and previous exploration. The interpreted geology summarises the area to be Paleo – Proterozoic in age and it is considered prospective for IOGC style deposits. |
