New “Ready1” Ni-PGE Target Defined and Drilling Imminent at Yandal West Highlights
-
A new highly prospective Nickel-PGE Target, Ready1, defined on Great Western’s 100% owned tenure
-
Ready1 has coincident Nickel-PGE geochemical and geophysical anomalism and is located on interpreted major geological structures. Ready1 is a 4km long by 1km wide NW-SE striking Ultrafine+ Ni-PGE anomaly
-
Great Western interprets Ready1 to share similarities with the Norilsk Deposit (Siberia), one of the world’s largest nickel deposits
-
Two discrete parallel anomalous Nickel-PGE trends have also been identified immediately west of Ready1
-
Infill Ultrafine+ soil sampling has already been completed at Ready1, with planning for refined geophysical survey currently underway, to be followed by drill testing
-
The Company is also delighted to report that drilling of the six significant Yandal West Targets will commence in late-May/first week of June 2022.
Great Western Exploration Limited (ASX: GTE) (“Great Western” or “the Company”) is pleased to announce a new and highly prospective Nickel-PGE target, “Ready1”, located within Great Western’s 100% owned tenure, 45km’s north of Wiluna (see Figure 1 ).
Ready1 Nickel-PGE Target (100% GTE)
The Ready1 Nickel-PGE target has been defined by Ultrafine+ soil sampling and an anomalous electromagnetic response from Geoscience Western Australia’s SkyTem (AEM) survey. Interpretation of the AEM survey by Great Western and in conjunction with geophysical consultant Newexco, revealed stacked, conductive structures that strongly correlate to a 4km long by 1km wide NW-SE striking Ultrafine+ Ni-PGE anomaly ( Figure 2 ).

Figure 1: Great Westerns Project Location Map
Great Westerns’ field investigation of Ready1 gives further encouragement of the target’s potential. A mineralised basalt outcrop has been identified, with a petrological study identifying the outcrop as a tholeiitic basalt/dolerite, mineralised with minor pyrite and trace magnetite and chalcopyrite. It is interpreted that this mineralised mafic outcrop and associated Ni-PGE anomalism is prospective for Norilsk (Siberia) style deposits, one of the world’s largest nickel deposits.

Figure 2: Ready1 Anomalous Nickel-Platinum soil and electromagnetic anomaly and parallel discrete anomalism west of this target
Additionally, two parallel trending and discrete platinum anomalies were identified immediately west of Ready1, also with coincident anomalous electromagnetic response (see Figure 2 ). The most continuous of these anomalies measures near 10km along strike.
Exploration is being prioritised for the Ready1 target and the nearby parallel Ni-PGE anomalies, infill Ultrafine+ soil sampling has already been completed and geophysical methods will be utilised and followed by drill testing.
Yerrida South Project (100% GTE)
Promising Ni-PGE-Cu anomalism was identified at the Yerrida South Project, located 50km southsouth-east of Sandfire’s (ASX: SFR) DeGrussa copper-gold operation ( Figure 3 ). A total of 2,079 assays from a 3,108 Ultrafine Sampling program were received, identifying several anomalous zones. Great Western anticipates that the forthcoming further work on this anomalism will result in a number of compelling drill targets being defined.

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 (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. |
Soil Sampling For the Golden Corridor please see GTE ASX Announcement-Gold in-Soil Anomalies Defined over Structural Targets at Golden Corridor - 3/03/2022. • A total of 2079 primary soil samples have been collected from the Yerrida South tenements. Sample spacing was either at 1600m x 800m, 800m x 800m, or 400m x 400m. • A ~200g sample has been collected from each site using metal digging tools and a 0.9mm sieve. Samples have been retrieved from the >10cm soil horizon (B-soil horizon), passed through the sieve, and collected in a soil-geochemistry bag. • Industry standard procedures have been used to minimise sample site contamination. • Field samples have been prepared by LabWest Minerals Analysis Pty Ltd (LabWest). A 2g charge weight of <2μm material has been collected from each sample for UltraFine analysis. |
| Drilling techniques • Drill type (eg core, reverse circulation, open-hole hammer, rotary air blast, auger, Bangka, sonic, etc) and details (eg 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). | |
| 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 and grade and whether sample bias may have occurred due to preferential loss/gain of fine/coarse material. |
No drill results reported. |
| 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. |
Soil Sampling • A basic description of the sample location was recorded by field staff. • A photograph of each sample and location has been taken. |
| 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. |
Soil Sampling • Field soil sampling was completed by trained Apex Geoscience Ltd. (Apex) field technicians using internal procedures to avoid sample contamination and ensure representative samples are taken by; cleaning sampling equipment between samples, removing jewellery during sampling, only collecting samples when the soil was dry enough to do so, taking several scoops from the bottom of sample holes, and sieving to remove large soil particles. • Sub-sampling was completed by the independent and certified laboratory, LabWest (Perth), using internal QC procedures. The 2g sub- sample of <2μm material is appropriate to analyse the ultrafine particles and assure sample representivity. • Field duplicate samples were collected and assessed at a rate of 1:50. |
| 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. |
Soil Sampling • Samples were submitted to LabWest in Perth for gold and multi-element analysis utilising the Ultrafine method, a technique developed in |

| widths and intercept lengths 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’). |
|
| 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. |
Soil Sampling • Plan view of sample location included within Appendix 1. |
| 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. |
Soil Sampling • Individual assays not reported, results have been summarised within the Appendix 1 statistics table. |
| 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. |
