HIGHLIGHTS
-
132N deposit Mineral Resource doubles in Nickel tonnes, with the estimate now 460,000 tonnes at 2.0% nickel for 9,050 tonnes of contained nickel
-
The 132N Mineral Resource is located between 80 and 350 metres below and north of a previous open pit mined by Western Mining Corporation
-
Global Mineral Resources at the Mt Edwards project increased to 8.72 million tonnes at 1.7% nickel for 146,000 tonnes of contained nickel across 11 deposits
-
Exploration continues at Lake Eaton South prospect with diamond and RC drilling
Neometals Ltd ( ASX: NMT ) ( “Neometals” or “the Company” ) is pleased to announce an updated nickel sulphide Mineral Resource at its 132N deposit (“ 132N ”), estimated in accordance with the 2012 JORC Code. 132N forms part of the Mt Edwards Project located in a province of historic nickel sulphide mines. Using historical and new assay data the reinterpreted Mineral Resource estimate at 132N has more than doubled the amount of contained nickel from 4,070 to 9,050 tonnes.

A diamond core drillhole and daughter wedge was undertaken at 132N in June 2018 to test for strike extensions of the historical Mineral Resource. Drilling generated a significant intercept of 15.6 metres at 1.24% nickel and has improved the understanding of the interpreted geology.
The re‐estimation of the 132N Mineral Resource follows a major review of the Mt Edwards project since mid‐2019, which has included an audit of the drill database and the historical exploration and mining literature.
The scope to further grow Mt Edwards has driven consideration of a future work program that will include reverse circulation (“ RC ”) and diamond core drilling to further test the mineralisation, including infill drilling to increase confidence sufficient to ‘upgrade’ the Mineral Resource classification. Future drilling and sampling will be used to further improve the understanding of the mineralogy and metallurgical characteristics to pave the way for advanced mining studies at 132N.
In addition, Neometals has recently completed targeted geophysical surveys and drill programs at its Lake Eaton South prospect and future work will be driven by further assay outcomes. Neometals continues to build a pipeline of short lead time deposits to realise value at Mt Edwards.

5 October 2020 – 132N NICKEL MINERAL RESOURCE AND EXPLORATION UPDATE AT MT EDWARDS
----- End of picture text -----
Background
Neometals acquired the Mt Edwards project in the first half of 2018 and immediately began exploring for nickel and lithium. Neometals is targeting new discoveries at Mt Edwards while reviewing and enhancing existing Mineral Resources. The company holds mining tenements with a large land holding of more than 300km[2] across the Widgiemooltha Dome, a well‐recognised nickel sulphide mining province.
Updating of the Mineral Resource estimate at the 132N deposit has expanded the global Mt Edwards Project Mineral Resources to 8.72 million tonnes at 1.7% nickel for 146,000 tonnes of contained nickel across 11 deposits.

Mineral Resource Estimation
The 132N Mineral Resource was estimated by Richard Maddocks from Auralia Mining Consultants and reviewed by Snowden Mining Industry Consultants.
The Mineral Resource estimate for the 132N Deposit of 460,000 tonnes at 2.0% nickel for 9,050 nickel tonnes is reported in accordance with the 2012 Edition of the ‘Australasian Code for Reporting of Exploration Results, Mineral Resources and Ore Reserves’ prepared by the Joint Ore Reserves Committee of The Australasian Institute of Mining and Metallurgy, Australian Institute of Geoscientists and Minerals Council of Australia (JORC Code) and follows a detailed interrogation and review of the available data, including the earlier reported Mineral Resource estimates by the previous holders of Nickel Mineral Rights on the tenement.

Location
The 132N nickel deposit is located on mining lease M15/101, approximately 6km north‐east of the Widgiemooltha Roadhouse. Access from the Coolgardie to Esperance Highway is via well‐established roads used for previous mining in the area. The 132N Mineral Resource is beneath an open pit, previously mined for Nickel in 1988 & 2008, and is located central to a line of 11 Nickel deposits at the Mt Edwards Project.
Neometals hold Mining Lease M15/101 along with a significant portion of the nickel prospective tenements around the Widgiemooltha Dome, located 50 kilometres from Kambalda.

Geology and Geological Interpretation
Nickel sulphide mineralisation in the region is predominantly associated with the basal contact of the komatiitic ultramafic with the underlying Mt Edwards Basalt. The mineralisation is found within embayments in the komatiite‐basalt contact interpreted to be thermal erosion channels caused by the flow of hot ultramafic lava. Sheet flow facies zones flanking and gradational to channel facies are thinner, texturally and chemically well‐differentiated and less magnesian than channel flow facies.
The 132N Mineral Resource is a nickel sulphide deposit hosted within the synclinal region of a parasitic, north plunging, isoclinal fold of the basalt‐ultramafic contact on the western limb of the Mount Edwards Anticline.
==> picture [293 x 472] intentionally omitted <==
Figure 2 ‐ Geology around 132N (pit outline shown in blue). Mineralisation on the ultramafic‐basalt contact is intensified on the axis of the parasitic syncline on the west limb of the Widgiemooltha Anticline
Within the pit the mafic footwall exhibits consistent near vertical dips of 80 to 89 degrees at 270[o] , except at the base of the structure where the dip shallows to 60 degrees. A coincident 40 degree north plunging anticlinal structure lies to the west of the major structure.
Figures 5 to 9 illustrate the geological interpretation of 132N in plan, long section and cross section.
The east and west limbs of the syncline have nickel mineralisation associated with the basal contact of the ultramafic unit, with thickening of the sulphides in the synclinal keel position. Blast hole data in the earlier open pit mining included drillhole intersections of very high nickel grades (up to 30%) recorded from the keel of the fold structure. Please note that blast hole data has not been used in the estimation of the 132N Mineral Resource but used as a tool to interpret the shape and grade relationships from previous mining.
There is no definitive structural model for the deposit. Faulting has been noted along strike resulting in the remobilisation of sulphides along the fault planes. Additionally, cross cutting faults have been interpreted that off‐set the mineralised zone by several meters. These cross‐cutting faults are reflected in the short strike length of some of the domains, especially towards the south near the open pit.
Nickel Mineralisation
The mineralisation styles range from weakly disseminated to very strong matrix sulphide mineralisation. Much of the mineralisation is disseminated with zones of matrix and massive sulphide.
Generally, the disseminated sulphide runs between 0.6 and 2.0% nickel with the matrix style mineralisation grading up to 3% nickel. Above 3% nickel represents a more massive style of mineralisation. Drilling has intersected massive sulphide zones with samples rich in pyrrhotite and pentlandite grading up to 14% nickel.
The disseminated and triangular‐textured sulphides with lenses or veins of matrix, massive or breccia sulphides occur in the tongue of ultramafic rocks formed by the syncline. 132N mineralogy includes cordierite and chondrodite (magnesium silicate, part of the humite group) suggesting a chemical interaction between granitic fluids and the high MgO ultramafic host.

Modelling
The mineralisation conforms to a Kambalda style komatiite flow hosted deposit, with post depositional structural modification. Geology logs were used to construct a basal surface to the ultramafic unit. This surface is the contact between the ultramafic and the underlying mafic basalts. The higher‐grade nickel mineralisation accumulates at or near this contact, and particularly in the “keel” and adjacent limbs of the syncline.
The mineralisation has been interpreted into nine domains of varying sizes commencing directly beneath the open pit and continuing over 500 metres of strike to the north‐north‐west. Domains were modelled and estimated with hard boundaries. Solid mineralised shapes were generally interpreted along strike representing elevated levels of nickel mineralisation.
There was no strict protocol in assigning a cut‐off grade to model these shapes, however they were based on the interpreted location of elevated nickel within the stratigraphic sequence. Mining experience in the pit showed that high grade sulphide mineralisation was somewhat discontinuous, so the interpreted mineralised shapes are representative of the overall mineralised zone rather than high grade nickel (>1%) mineralisation.
A top of fresh rock surface was modelled from the logging codes in drill holes. No mineralisation extending above this surface is reported in the Mineral Resource estimate as it has been mined previously.

Mineral Resource Classification
The majority of the 132N Mineral Resource has been classified as Inferred. The wide spaced drilling, lack of QAQC data in historic drilling and confidence in the geological interpretation all influenced this classification. The more recent drilling carried out in 2006‐08 by Titan Resources and Consolidated Nickel was focussed within and beneath the current mined pit. These recent holes have QAQC data that indicate appropriate levels of precision and accuracy in sampling and assaying. This 2006 to 2008 drilling increases the density of drilling and sampling, and thus the confidence in the Mineral Resource estimate.
Portions of the 132N Mineral Resource that are estimated in pass 1, using a minimum of 10 samples and 5 drill holes for nickel grade estimation, have been classified as Indicated. Isolated blocks and zones of Inferred blocks within predominantly Indicated areas were re‐classified as Indicated Mineral Resources for continuity. Figure 10 shows that most of the areas classified as Indicated are within the already mined pit, and hence are depleted from the reported Mineral Resource.

Drilling Techniques and Details
The drill database used in the Mineral Resource estimate is comprised of samples from diamond core drilling and RC drilling across several exploration campaigns from 1968 to 2018.
Information from 59,616 metres of Diamond Core and RC drilling across 729 drill holes are within the area used in the local geological interpretation and Mineral Resource estimation of 132N. Results from air‐core drilling and blast hole drilling have not been used in this Mineral Resource estimate.

INCO carried out drilling on the deposit in 1968‐1969, while Western Mining Corporation (“ WMC ”) conducted minor drilling in 1983‐1984, and drilling campaigns between 1989 and 1998, before and after the first phase of mining. Almost 50% of the total metres drilled on the Mineral Resource area was drilled by INCO, however many of these metres were drilled through barren overburden to reach the mineralisation at depth.

Not all drill holes in the 132N area are related directly to the 132N Mineral Resource, with some drill holes related to exploration for Lithium. Much of the northern extent of the 132N Mineral resource is proximal to the Atomic 3 Spodumene Lithium prospect drilled in 2017 and 2018, however minor intercepts of nickel mineralisation were recorded in this drilling.

Figure 11 ‐ A drillhole location plan with the collar locations of historic drilling at 132N
Due to the different drill directions, final drill spacing on the nickel mineralisation is quite irregular. Historic data originally recorded by INCO is in imperial measurements (200‐ and 100‐foot lines). WMC drilled at an irregular 20 to 40 metre line spacing and may have been subject to localised changes due to topography.
About 70% of the total INCO and WMC drilling was carried out as diamond drilling. No details on the drilling techniques used by INCO and WMC have been found. It is assumed that the INCO percussion drilling is open hole percussion. WMC’s early RC drilling probably utilised a cross‐over sub, while in the late 80’s and 90’s drilling likely took place by face‐sampling hammers. WMC diamond drilling was probably NQ size.
While the recorded information relating to RC chip samples collected before 2003 is scarce, it should be noted that the fundamental information such as geology, mineralogy and sample interval from this time is well recorded.
Drilling from 2003 to 2008 by Titan Resources and Consolidated Nickel includes further detailed information. For diamond core holes, half core was submitted pre‐Titan and quarter core post‐Titan. Core samples were cut to geological intervals in priority over cutting to mathematical intervals.

QAQC
QAQC procedures carried out by operators before 2003 are not known. The QAQC results are sourced from the Consolidated Nickel Mineral Resource Report from January 2007. This 2007 report indicated that no significant or material discrepancies were identified by the QAQC sampling/analysis for drilling and sampling conducted by Titan Resources or Consolidated Nickel.
The long section below shows the deposit wireframe domains with drill holes colour coded post‐ and pre‐2003 drilling programs. The post‐2003 holes have been focussed on the area immediately surrounding the mined pit. These holes were drilled by Titan Resources and Consolidated Nickel and have more complete descriptions of drilling, sampling and assaying procedures. In addition, they have undergone a program of QAQC analysis. This is one of the considerations that was taken into account when classifying the Mineral Resources, and generally zones without post‐2003 drilling are classified as inferred.

Estimation Methodology
All elements typically required in mine studies for nickel sulphide were estimated using ordinary kriging. There are 938 drill hole composites used in the estimate. Grade estimation for nickel, copper, cobalt, sulphur and arsenic was completed using ordinary kriging in 3 passes with the search ellipses aligned with the strike and dip of the basal contact.
For nickel, the first pass search extents were based on the range indicated by the variography, the second pass was based on a 50% increase and the third pass 300% from pass 1. Other elements were estimated using a 100% increase for pass 2 and a 400% increase for pass 3. For MgO and Fe₂O₃ the second pass was 400% of pass 1.There was no third pass.
For arsenic in the large domain 2, to ensure all blocks were populated with an arsenic grade the search dimensions in pass 3 were 5 times the size than those used in pass 1. Not all drill holes have been assayed for all the modelled variables, so the data density is somewhat variable and the search extents in passes 2 and 3 vary to reflect this.
Each domain has a slightly different dominant dip. The nickel mineralisation, derived from variography, has a plunge of 15° towards 345. Domains 1 and 2 curve around the mafic/ultramafic contact so an unfolding projection model was appropriate in estimating grades in these two domains.
Table 5 ‐ Search directions for each domain
| Domain | Bearing | **Plunge ** | Dip |
|---|---|---|---|
| domain 1 | 165 | unfolded | |
| domain 2 | 165 | unfolded | |
| domain 3 | 165 | 15 | ‐70 |
| domain 4 | 165 | 15 | ‐85 |
| domain 5 | 165 | 15 | ‐75 |
| domain 6 | 165 | 15 | ‐85 |
| domain 7 | 165 | 15 | ‐80 |
| domain 8 | 165 | 15 | ‐75 |
| domain 9 | 165 | 15 | ‐85 |
| ultramafic | 165 | 0 | ‐80 |
Top cuts have been applied to some of the modelled variables based on cumulative log frequency graphs and coefficients of variation (CV). Top cuts have not been applied to nickel, cobalt, MgO and Fe₂O₃.
Table 6 ‐ Top Cuts applied
| Variable | Cut | Uncut mean | Cut Mean | Uncut CV | Cut | |
|---|---|---|---|---|---|---|
| Ni | none | 2.20 | 2.20 | 1.15 | 1.15 | |
| Co | none | 274 | 274 | 1.13 | 1.13 | |
| Cu | 10000ppm | 1,555 | 1,481 | 1.51 | 1.27 | |
| Fe₂O₃ | none | 13.03 | 13.03 | 0.41 | 0.41 | |
| **MgO ** | none | 22.46 | 22.46 | 0.33 | 0.33 | |
| S | 90000ppm | 29,466 | 26,506 | 1.21 | 1.00 | |
| As | 5000ppm | 673 | 457 | 4.38 | 2.17 |
Arsenic and MgO do not appear to be correlated with nickel mineralisation. Elements which occur within the sulphide mineralisation and are correlated more closely with nickel, i.e. Co, Cu, S, Fe₂O₃, are modelled within the nine domains based on accumulations of sulphide mineralisation. Arsenic and MgO are not part of this population so have been modelled within the broader ultramafic package that contains the sulphide mineralisation.
It is thought that arsenic has largely been introduced into the mineralised zone through later geological processes, possibly via arseniferous fluids in post nickel mineralisation faults and/or shears. Arsenic is concentrated in domains 2 and 3, indicating a possible geological or structural control.
Figure 14 illustrates the relationship between nickel and sulphur, and nickel and arsenic. Nickel and sulphur show a strong, direct linear relationship, whereas the nickel‐arsenic association is less clear.

Model Validation
All elements were estimated using ordinary kriging. The block model grades for the total Mineral Resource estimate, and individually for each domain, has been compared with the mean composite grades for the total and each domain. The variation between composites and block grades is generally within acceptable limits and does not display any significant bias.
The mean composite grade is the mean of all the drill composites within the domain and the block grade is the average block model grade within the domain with no cut‐off grade applied. A swath plot analysis indicates that the model does represent the underlying composite data, except for where there is limited composite data.
The 132N Mineral Resource model, the drill database and other supporting information was supplied to Snowden Mining Industry Consultants for peer review. Snowden did not identify any fatal flaws and replicated the nickel tonnage and grade reported by Auralia to within acceptable limits. Snowden made several observations, many of which were incorporated into the final Mineral Resource estimate.
Previous Mineral Resource Estimates
Further validation includes comparison with previous models. The four estimates tabled below have comparable levels of drill and sample data. In 2016 Apollo Phoenix had the 2008 Consolidated Minerals estimate for 132N reviewed and validated. The estimation techniques were modified by Apollo Phoenix, however no geological reinterpretation was carried out.
Table 7 – Comparison with previous 132N Mineral Resource Estimations
| Company | Year | Tonnes | Nigrade % | Contained Ni | Cut‐offgrade % | ||
|---|---|---|---|---|---|---|---|
| Consolidated Nickel | 2007 | 282,600 | 2.2 | 6,200 | 1.0 | ||
| Consolidated Nickel | 2008 | 200,000 | 3.1 | 6,200 | 1.0 | ||
| Apollo Phoenix | 2016 | 116,000 | 3.38 | 3,907 | 1.0 | ||
| Neometals | 2020 | 460,000 | 2.0 | 9,050 | 1.0 |
The current 2020 interpretation is compared to the Consolidated Nickel 2008 interpretation in Figure 15 below. The increase in tonnes in the 2020 model compared to previous models is clearly apparent with the 2020 model presenting a more continuous mineralised structure than the 2008 model. The competent person is of the opinion that the previous models were too selective in the construction of nickel mineralisation solid shapes. Shapes appear to have been interpreted based on very few, high grade drill intersections. The competent person is of the opinion that this will potentially result in an unrealistically high‐grade interpretation as it essentially does not consider lower grade drill intersections even though they are contained within the same mineralised structure.
The competent person believes that the current 2020 geology interpretation and grade block model are fair representations of the in situ mineralisation.

Mining and Metallurgical Considerations
Mining and metallurgical factors or assumptions were not explicitly used in estimating the Mineral Resource. Only the primary or fresh rock zone of the 132N nickel sulphide mineralisation has been reported in the Mineral Resource.
It is assumed that underground mining methods would be used for any future mining operations, with the development of a portal using the existing open pit as an entry point to the decline.
A nickel cut‐off grade of 1.0% is considered the most appropriate for the Mineral Resource estimate, however, the mineralisation is robust and maintains some continuity when higher cut‐off grades are applied. The 1% nickel cut‐off grade is considered to approximate economic mining cut‐off grades for an underground mining scenario comparable to recently published updated underground nickel Ore Reserves and Mineral Resources in the area.
The distribution of high‐grade arsenic and magnesium requires further delineation and a more detailed interpretation will be needed for the planning of any future economic extraction.
Future Work
Future work at 132N may include additional infill RC and diamond core drilling so that a thorough structural and geo‐metallurgical interpretation of the deposit can be incorporated into an upgraded Mineral Resource Estimate.
Controls on high grade nickel mineralisation appear to be complex. Closer spaced drilling, along with an increased understanding of the structural history of the deposit, should increase confidence in the distribution of high‐grade nickel mineralisation sufficient to upgrade more of the Mineral Resource to Indicated classification, or even to Measured classification.
Arsenic is an important element in nickel sulphide deposits due to its deleterious impact on processing. The drilling described above would increase the understanding of the distribution of arsenic mineralisation. Mapping in the 132N pit should also be undertaken to identify arsenic rich shears.
Nickel mineralisation remains open at depth so further drilling will test the extent of the Mineral Resource. It is also suggested to test the contact ultramafic‐basalt contact to the west of the 132N Mineral Resource. Down Hole Electromagnetic surveys (DHEM) will be carried out where possible for all future drilling at 132N to aid in the delineation and discovery of conductive nickel sulphide mineralisation.
Diamond core drilling and sampling will improve the understanding of the structural orientation, geotechnical attributes, mineralogy, and metallurgical characteristics to pave the way for advanced mining studies.

Exploration at Lake Eaton and Lake Eaton South
Following on from Passive Seismic, Moving Loop Electromagnetic and UAV magnetic geophysical surveys completed in 2020 Neometals have undertaken exploration drilling at its Lake Eaton South prospect. Three diamond holes were drilled in late June through to the end of July, and seven RC holes were completed from late August into September 2020.

Figure 18 ‐ 3D perspective view of modelled plates ME01 to ME07 interpreted from the MLEM survey across Lake Eaton
The first diamond hole, MEDD001, targeted the MEC3 conductor plate modelled by exploration consultants Newexco from a Moving Loop Electromagnetic survey carried out in June 2020. The MEC3 conductor plate has a conductance of ~7,000 siemens starting at a depth of ~220 metres below surface. The interpreted plate is 760 metres long and 725 metres deep.
MEDD001 was collared into Mining Lease M15/78 approximately 800 metres south west of Mincor Resource’s ( Mincor ) Cassini deposit. The hole was drilled at ‐60[o] toward the east north east and cored through basalt to 343 metres before hitting ultramafic with sulphide enrichment.
The sulphide mineralisation was intercepted within 15 metres of the modelled conductor plate. Layers of ultramafic and sedimentary shale were logged until the end of hole at 454 metres. Assaying of quarter core from prospective zones has showed no significant nickel mineralisation. Neometals drilled diamond core holes MEDD002 & MEDD003 on Exploration Licence E15/1553 following on from nickel mineralisation encountered in RC and Air core drilling in December 2019, reported in ASX announcement on 31 January 2020 “ Further Massive Nickel Sulphide Results from Mt Edwards” .

– Figure 19 Pyrite and pyrrhotite sulphide stringers at 384m in MEDD001
MEDD002 drilled under MERC101 and MEAC108, and did not intercept any significant nickel mineralisation, although there was significant sulphide mineralisation on the ultramafic‐basalt contact at 170.9 metres.
MEDD003 drilled under MERC100 and intercepted nickel sulphide from 139 metres downhole, with the ultramafic‐basalt contact at 145.7 metres. Assaying of quartered core proves that while grades are modest, the area is fertile for nickel sulphide mineralisation. The mineralised intercept is 5.06 metres at 0.66% nickel from 139 metres downhole, including 0.98 metres at 1.36% nickel from 141 metres.
Seven RC holes have been drilled on E15/1553 and E15/989 testing for nickel mineralisation and the ultramafic‐basalt contact. Assay results for samples from these seven RC holes are pending. Drill holes MERC109, MERC110 and MERC111 have been drilled on the same section line as MEDD002 & MEDD003 on E15/1553, while drill holes MERC112 to MERC115 have been collared north‐west of these on E15/989 and drilled to the east. An ultramafic‐basalt contact has been seen in holes MERC113 to MERC115, supporting the interpretation from the magnetics of a fault with sinistral offset north of MEDD002, as shown in Figures 20 & 21.

Drill location and assay results from Mincor’s Cassini and Cassin North
The information in this report that relates to Exploration Results at Mincor’s Cassini and Cassini North are sourced from Mincor’s ASX announcements listed below. Mincor’s results are provided as a reference point to the potential mineralisation on Neometals’ tenements on the basis that the interpreted geological contact related to nickel mineralisation continues along strike onto Neometals’ tenements. This interpretation is supported by surface and airborne geophysics, as well as geochemistry and petrology from drilling.
Mincor’s results are not Neometals results and have not been independently verified by Neometals. No inferences should be made as to the potential or value of Neometals’ project or Neometals itself based on Mincor’s results.

APPENDIX 1: Table 1 as per the JORC Code Guidelines (2012)
| Section 1 Sampling Techniques and Data | Section 1 Sampling Techniques and Data | |
|---|---|---|
| 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. |
Consolidated Nickel used RC and diamond core drilling with RC sampling based on 1m intervals. Core was split and submitted as half core or quarter core. Titan, Consolidated Nickel and Neometals core and RC sampling procedures were as follows; Diamond drill core is orientated using a spear every 3 metres. The core is marked up by geologists and cut by ALS. The core is halved and then one half is cut in half again to produce ¼ core. The ¼ core is sampled for assaying. The core is sampled to the mineralisation contacts and at 1 m intervals through the mineralisation. Sampling continues for 10 m below the mineralisation footwall and 10m above the hanging wall. Non mineralised material is not sampled. Sample piles are produced at 1m intervals from RC drill holes. The sample piles are usually sampled as either 1 m or 4m composites. A representative scoop is taken through the sample pile. An anomalous 4 m composite sample is resampled at 1m intervals |
| 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). |
The 132N Mineral Resource is predominantly based on diamond core and RC drilling techniques. Within the mined pit there is some grade control drilling and possibly trench or channel sampling that has been used in the estimation. This has already been mined out and does not impact significantly on the estimation of mineralisation beneath the pit. Reported Lake Eaton South drilling is HQ and NQ Diamond Core and RC |
| Drill Sample Recovery |
Method of recording and assessing core and chip sample recoveries and results assessed. |
Sample recovery of drilling prior to 2000 is not known. No relationship between sample recovery and grade has been recognised. Sample Recovery at Lake Eaton South has been good for both diamond core and RC drilling |
| 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 topreferential loss/gain of fine/coarse material. |

| Section 1 Sampling Techniques and Data | Section 1 Sampling Techniques and Data | |
|---|---|---|
| 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. |
All drill holes have been geologically logged for lithology, weathering, alteration and mineralogy. All samples were logged in the field at the time of drilling and sampling (both quantitatively and qualitatively where viable), with spoil material and sieved rock chips assessed. |
| 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. |
Information relating to RC chip samples collected before 2003 is scarce. Information such as sample interval is well recorded. Past workers have verbally informed that Titan samples were collected in 1m or 2m intervals, after passing through a cyclone, and split via a 50:50 or 75:25 riffle splitter. Approximately 3-5kg of sample was submitted for analysis, and the remaining sample left in plastic bags at drill sites (these sites have since been rehabilitated). Since 2003 chip samples have been collected in 1m intervals via a cyclone and split using a 75:25 riffle splitter. Approximately 3-5kg of sample was sent to the laboratory for analysis and the remainder laid out book fashion as 1 m intervals generally in 20m rows. Details as to the sampling of wet holes pre 2003 are unknown. Post 2003 wet holes have not been encountered as the rigs utilized had sufficient air to keep the holes and therefore samples dry. For diamond core holes, half core was submitted pre-Titan and quarter core post-.Titan. Core samples were cut to geological intervals rather than cut to mathematical intervals. |
| Quality of assay data and laboratory tests |
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. |
QAQC procedures carried out by operators before 2003 are not known. The QAQC results sourced from the Consolidated Nickel Mineral Resource Report from January 2007 indicated that no significant or material discrepancies was identified by the QAQC sampling/analysis for drilling and sampling conducted by Titan Resources or Consolidated Nickel. The procedures implemented by Titan and Consolidated Nickel included standards, field duplicates and different lab checks for all elements modelled. |
| Quality of assay data and laboratory tests cont. |
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 (eg standards, blanks, duplicates, external laboratory checks) and whether acceptable levels of accuracy (ie lack of bias) and precision have been established. |
Pre 2001 samples (WMC) were submitted to the Silver Lake Laboratory for analysis. Little is known about the laboratory used however it is believed that on the basis of information subsequently collected there is no reason to doubt the assays. Detection limits are not often recorded on the available data and the analytical scheme cannot be verified. According to WMC it was standard practice to submit duplicates and standards. It has been noted that many nickel samples from Widgiemooltha and Kambalda were analysed at the Silver Lake Laboratory and there is no basis for believing the analytical results to be incorrect. Post 2003 reputable laboratories, namely ALS Chemex (ALS) and Ultra Trace Pty Ltd, were utilized. These |

| Section 1 Sampling Techniques and Data | Section 1 Sampling Techniques and 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. Specification of the grid system used Quality and adequacy of topographic control |
MGA94_51S is the grid system used in this program. Historic survey methods are not known but INCO and WMC data was originally recorded in in local grids that have been converted to current MGA data. This conversion may have introduced some small errors. Downhole survey using Reflex gyro survey equipment was conducted during the program by the drill contractor. Older drill holes used single shot cameras, some do not have azimuth data due to interference of steel drill rods. Downhole Gyro survey data were converted from true north to MGA94 Zone51S and saved into the data base. The formulas used are: Grid Azimuth = True Azimuth + Grid Convergence. Grid Azimuth = Magnetic Azimuth + Magnetic Declination + Grid Convergence. The Magnetic Declination and Grid Convergence were calculated with an accuracy to 1 decimal place using plugins in QGIS. Magnetic Declination = 0.8 Grid Convergence= -0.7 |
| 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. Whether sample compositing has been applied |
All RC drill holes were sampled at 1 metre intervals down hole. Select sample compositing has been applied at a nominal 4 metre intervals determined by the geologist. Historic RC drilling was at a minimum of 1m in mineralised zones. Some non-mineralised areas were sampled at larger intervals of up to 4m. Diamond core was sampled to geological contacts with some samples less than 1m in length. |
| 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 mineralised structures is considered to have introduced a sampling bias, this should be assessed and reported if material. |
Drilling has generally been oriented perpendicular to strike at dips from -45 to -90 degrees. Intersections are generally not true lengths. There is no significant bias introduced due to drilling orientation. |
| Sample security |
The measures taken to ensure sample security | Historic security measures are not known. For Lake Eaton South all samples collected during the current nickel exploration program were transported personally by Neometals and/or geological consultant staff to a commercial laboratory in Kalgoorlie for submission. |

| 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. |
Neometals (Mt Edwards Lithium Pty Ltd) hold all mineral rights other than gold on Mining Lease M15/101. Neometals (Mt Edwards Lithium Pty Ltd) hold all mineral rights on Exploration Licence E15/1553. Mincor hold E15/989 and M15/78 with Neometals (Mt Edwards Lithium Pty Ltd) holding Nickel Mineral Rights. |
| Exploration done by other parties |
Acknowledgment and appraisal of exploration by other parties. |
Neometals have held an interest in M15/101 since June 2018, hence all prior work has been conducted by other parties. The ground has a long history of exploration and mining and has been explored for nickel since the 1960s, initially by INCO in the 1960’s and then Western Mining Corporation from the early 1980’s. Numerous companies have taken varying interests in the project area since this time. Titan Resources held the tenement from 2001. Consolidated Minerals took ownership from Titan in 2006, and Salt Lake Mining in 2014. On E15/1553 and E15/989 the history of exploration is limited, with only a small number of drill holes recorded on public file used in the planning of the reported drilling. |
| Geology | Deposit type, geological setting and style of mineralisation. | The geology at 132N comprises of sub-vertically dipping multiple sequences of ultramafic rock, metabasalt rock units and intermittent meta- sedimentary units. There is a synformal structure at 132N. Contact zones between ultramafic rock and metabasalt are considered as favourable zones for nickel mineralisation. The reported nickel mineralisation at 132N is wholly contained within fresh rock. The geology at Lake Eaton South is still being interpreted, but is sequences of ultramafic rock and metabasalt rock units. |
| 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: easting and northing of the drill hole collar elevation or RL (Reduced Level – elevation above sea level in metres) of the drill hole collar dip and azimuth of the hole down hole length and interception depth hole length. If the exclusion of this information is justified on the basis that the information is not Material and this exclusion does not detract from the understanding of the report, the Competent Person should clearly explain why this is the case. |
Relevant drill hole information for 132N and Lake Eaton South has been tabled in the report including hole ID, drill type, drill collar location, elevation, drilled depth, azimuth, dip and respective tenement number. Historic drilling completed by previous owners has been verified and included in the drilling database. |

| Data aggregation methods |
In reporting Exploration Results, weighting averaging techniques, maximum and/or minimum grade truncations (eg 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. |
Samples assessed as prospective for nickel mineralisation were assayed at single metre sample intervals, while zones where the geology were considered less prospective were assayed at a nominal 4 metre length composite sample. |
| 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 (eg ‘down hole length, true width not known’). |
Nickel mineralisation is hosted in the ultramafic rock unit close to the metabasalt contact zones. All drilling is angled to best intercept the favourable contact zones between ultramafic rock and metabasalt rock units to best as possible test true widths of mineralisation. Due to the steep orientation of the mineralised zones there will be minor exaggeration of the width of intercepts. |
| 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, sections and tables are included in the body of the Report |
| 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. |
Current understanding of 132N is based on historical mining, mapping, drilling and sampling conducted by previous owners of the tenement. The geology of the 132N deposit is well known. Understanding of the relationship between Lake Eaton South and the prospects to the south continue to be investigated. |
| 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. |
No further exploration data has been collected at this stage for 132N. Assay results of RC drilling at Lake Eaton South are pending. |
| Further work | The nature and scale of planned further work (eg tests for lateral 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. |
Further drilling is recommended to test the potential lateral extents and infill areas for nickel mineralisation at 132N. |

| Database integrity |
Measures taken to ensure that data has not been corrupted by, for example, transcription or keying errors, between its initial collection and its use for Mineral Resource estimation purposes. Data validation procedures used. |
The database is an accumulation of exploration by several companies. Data were inspected for errors. No obvious errors were found. Drillhole locations, downhole surveys, geology and assays all corresponded to expected locations. |
| Site visits | Comment on any site visits undertaken by the Competent Person and the outcome of those visits. If no site visits have been undertaken indicate why this is the case. |
The competent person for the 132N Mineral Resource has visited the site. An inspection of the site was conducted on 17 March 2020. The competent person for exploration results has spent more than 30 days at site since 2018. |
| Geological interpretation |
Confidence in (or conversely, the uncertainty of) the geological interpretation of the mineral deposit. Nature of the data used and of any assumptions made. The effect, if any, of alternative interpretations on Mineral Resource estimation. The use of geology in guiding and controlling Mineral Resource estimation. The factors affecting continuity both of grade and geology |
There are sufficient drill intersections through the mineralisation and geology to be confident of the geological interpretation at 132N. These types of nickel deposits have been mined in the Kambalda/Widgiemooltha region for many years and the geology is well documented. The basal contact of the ultramafic overlying mafics has been accurately located through many drill hole intersections. The nickel enriched base of the ultramafics also has been accurately determined through drill intersections. The basal contact corresponds closely with the higher-grade nickel mineralisation. High grade nickel is distributed along a narrow, convoluted ribbon extending down dip along the basal contact. Remobilisation of massive sulphides may complicate this distribution. There are possibly some structural discontinuities that displace the ore-zones resulting in three discrete domains. Geological Interpretation is ongoing at Lake Eaton South. |
| Dimensions | The extent and variability of the Mineral Resource expressed as length (along strike or otherwise), plan width, and depth below surface to the upper and lower limits of the Mineral Resource. |
The modelled 132N deposit has a strike extent of 1,500m and a vertical down dip extent of about 450m. The mineralised zones are from about 1m to 10m wide. |

|---|---|---|
| Estimation and modelling techniques |
The nature and appropriateness of the estimation technique(s) applied and key assumptions, including treatment of extreme grade values, domains, interpolation parameters and maximum distance of extrapolation from data points. If a computer assisted estimation method was chosen include a description of computer software and parameters used. The availability of check estimates, previous estimates and/or mine production records and whether the Mineral Resource estimate takes appropriate account of such data. The assumptions made regarding recovery of by- products. Estimation of deleterious elements or other non-grade variables of economic significance (eg sulphur for acid mine drainage characterisation). In the case of block model interpolation, the block size in relation to the average sample spacing and the search employed. Any assumptions behind modelling of selective mining units. Any assumptions about correlation between variables. Description of how the geological interpretation was used to control the resource estimates. Discussion of basis for using or not using grade cutting or capping. The process of validation, the checking process used, the comparison of model data to drill hole data, and use of reconciliation data if available. |
The estimation was completed using ordinary kriging. Nine mineralised domains were estimated representing the basal accumulation of nickel bearing sulphides. Lower levels of nickel mineralisation representing non sulphide nickel in the ultramafic rocks were generally not included however sometimes for continuity of domain modelling lower grade intersections were included. The mineral resource was estimated using Vulcan v12. Also modelled were Fe2O3, MgO, As, Co, Cu, S. Composites were modelled at 1m intervals to reflect the dominant sample intervals in the database. The block size was 10mX, 25mY, 10mZ. A sub-block size of 1.25Mx, 1.25My, 1.25Mz was used to accurately model the narrow ore horizon. The larger parent block size of 10x25x10 was used in grade estimation in areas of wider drill spacing, other areas used a block size of 5x10x5. The search directions were based on the orientation of the mineralised horizon. A three-pass estimation was used, pass 1 reflected the variography dimensions and passes 2 and 3 were significantly larger to ensure all blocks within the domain were estimated. No assumptions were made on correlation of modelled variables. Each modelled variable was estimated in its own right. All elements were modelled using ordinary kriging. Top cuts were applied to arsenic, copper and sulphur based on coefficient of variation analysis and cumulative log normal graphs. |
| Moisture | Whether the tonnages are estimated on a dry basis or with natural moisture, and the method of determination of the moisture content. |
Estimates are on a dry tonne basis |
| Cut-off parameters |
The basis of the adopted cut-off grade(s) or quality parameters applied. |
The cut-off grade of 1% Ni used for reporting corresponds to a potential mining cut-off grade appropriate for underground mining methods. |
| Mining factors or assumptions |
Assumptions made regarding possible mining methods, minimum mining dimensions and internal (or, if applicable, external) mining dilution. It is always necessary as part of the process of determining reasonable prospects for eventual economic extraction to consider potential mining methods, but the assumptions made regarding mining methods and parameters when estimating Mineral Resources may not always be rigorous. Where this is the case, this should be reported with an explanation of the basis of the mining assumptions made. |
While no mining factors have been implicitly used in the modelling, the model was constructed with underground mining methods most likely to be used. |
| Metallurgical factors or assumptions |
The basis for assumptions or predictions regarding metallurgical amenability. It is always necessary as part of the process of determining reasonable prospects for eventual economic extraction to consider potential metallurgical methods, but the assumptions regarding metallurgical treatment processes and parameters made when reporting Mineral Resources may not always be rigorous. |
No metallurgical factors have been assumed. Modelling only extended to the top of fresh rock to ensure only sulphide nickel mineralisation was estimated. |
| Environmental factors or assumptions |
Assumptions made regarding possible waste and process residue disposal options. It is always necessary as part of the process of determining reasonable prospects for eventual economic extraction to consider the potential environmental impacts of the mining and processing operation. While at this stage the determination of potential environmental impacts, particularly for a greenfields project, may not always be well advanced, the status of early consideration of these potential environmental impacts should be reported. Where these aspects have not been |
No environmental factors or assumptions were used in the modelling. |

||
| Bulk density | Whether assumed or determined. If assumed, the basis for the assumptions. If determined, the method used, whether wet or dry, the frequency of the measurements, the nature, size and representativeness of the samples. The bulk density for bulk material must have been measured by methods that adequately account for void spaces (vugs, porosity, etc), moisture and differences between rock and alteration zones within the deposit. Discuss assumptions for bulk density estimates used in the evaluation process of the different materials. |
Bulk density within the mineralised horizon was estimated with a regression formula derived from 2,197 measurements on 43 diamond drill holes. The formula used is: Bulk Density (t/m3) = (0.0702 x Ni %) + 2.8316 Weathered material was assigned a density of 2.2. Fresh Mafic waste 2.7 and ultramafic waste 2.8 |
| Classification | The basis for the classification of the Mineral Resources into varying confidence categories. Whether appropriate account has been taken of all relevant factors (i.e. relative confidence in tonnage/grade estimations, reliability of input data, confidence in continuity of geology and metal values, _quality, quantity and distribution of the data. _ |
The 132n Mineral Resource has been classified as Indicated and Inferred. Indicated resources were based on a minimum of 5 drill holes per estimate and 10 samples per estimation. Indicated resources are found in the areas of recent drilling where the drill density is greater and there is adequate QAQC data supporting the drilling, sampling and assaying. This classification reflects the Competent Person’s view of the deposit. |
| Whether the result appropriately reflects the Competent Person’s view of the deposit. |
||
| Audits or reviews |
The results of any audits or reviews of Mineral Resource estimates |
Auralia Mining Consultants are independent of Neometals. Neometals provided a copy of the 132N Mineral Resource dataset and report to Snowden Mining Industry Consultants Pty Ltd to conduct a review. Snowden found no fatal flaws in the Mineral Resource estimate. |
| Discussion of relative accuracy/ confidence |
Where appropriate a statement of the relative accuracy and confidence level in the Mineral Resource estimate using an approach or procedure deemed appropriate by the Competent Person. For example, the application of statistical or geostatistical procedures to quantify the relative accuracy of the resource within stated confidence limits, or, if such an approach is not deemed appropriate, a qualitative discussion of the factors that could affect the relative accuracy and confidence of the estimate. The statement should specify whether it relates to global or local estimates, and, if local, state the relevant tonnages, which should be relevant to technical and economic evaluation. Documentation should include assumptions made and the procedures used. These statements of relative accuracy and confidence of the estimate should be compared with production data, where available. |
There is much drilling into the 132N orebody. The position of the nickel mineralised horizon has been well established as has the global grade. There appears to have been some remobilisation of massive nickel bearing sulphides, sometimes into the underlying mafics. This does impact on the continuity of the high-grade mineralisation. The stated tonnages and grade reflect the geological interpretation and the categorisation of the mineral resource estimate reflects the relative confidence and accuracy. |
