CONTINUED POSITIVE METALLURGICAL RESULTS FROM MT EDWARDS NICKEL PROJECT
HIGHLIGHTS
-
Flotation test-work on diamond core from 132N and Munda deposits confirms potential to generate commercially acceptable nickel concentrates;
-
Munda float program generated high grade concentrate (13% Ni grade) with strong recoveries (83.8% recovery) and displayed Fe:MgO ratios sought by smelters;
-
132N float program (lower feed head grade) also confirms successful sample upgrade (13.5% Ni grade in concentrate) with 62.8% recovery; and
-
Palladium deportment to the 132N concentrate (3.06g/t Pd) supporting further evaluation to quantify the potential for co-product revenue.
Project developer Neometals Ltd (ASX: NMT) (“ Neometals ” or “ the Company ”) is pleased to announce further encouraging results from preliminary metallurgical tests carried out at the Mt Edwards Nickel Project (“ Mt Edwards ”). Specifically, a successful flotation test-work program was carried out on mineralised samples derived from the 132N Deposit (“ 132N ”) Mineral Resource * and the Munda Deposit (“ Munda ”) Mineral Resource**. The results confirm, ‘in principle’, the ability of the mineralisation from both 132N and Munda to upgrade to commercially acceptable concentrate levels (+12% Ni grade).
Munda and 132N represent excellent near-term mining prospects warranting further studies. With this in mind, flotation testwork was carried out to determine if nickel mineralisation could be upgraded to commercial grade concentrate. This strategy follows on from earlier positive results at the Armstrong Deposit (“ Armstrong ”) where flotation test-work revealed the presence of potential co-products in addition to the contained nickel ( for full details refer to ASX announcement “High grade palladium in nickel concentrate results from Armstrong” released 9th April 2021).
The Munda flotation program yielded excellent recovery (83.8% recovery at 13.0% nickel concentrate grade) with a very favourable iron/magnesium oxide ratio which is highly desirous for smelting customers. Despite a lower sample nickel head grade (1.45% versus Mineral Resource grade 2.0%), the 132N flotation program yielded 62.8% recovery at 13.5% nickel concentrate grade. Importantly, the 132N test-work evidenced palladium in the concentrate (3.06g/t Pd) which supports further evaluation to quantify the potential for co-product revenue.
These metallurgical results, together with those previously announced at Armstrong, provide Neometals with encouragement regarding the potential to establish meaningful co-products from future operations at Mt Edwards. Further float work on the other deposits with near term exploitation prospectivity will be undertaken to close off processing and marketing aspects of the development study which aims to re-establish a viable production centre at Mt Edwards. Future metallurgical work will be undertaken with core from planned exploration drilling to provide fresh materials to test. Importantly, these fresh samples will generate more information on co-products and their deportment.

Key points noted from the metallurgical flotation test-work:
-
A blend of source material from both 132N and Munda deposits was mixed in order to achieve a head grade not dissimilar to the overall Mineral Resource grades for each deposit
-
Standard Kambalda Nickel Operations flotation reagent regime implemented
-
In the case of 132N
-
with limited source material, resultant test head grade was below the target range
-
presence of palladium and platinum were noted with upgrades of a factor of over two into the concentrate from mineralisation grades
-
similar recoveries of nickel and copper were noted
-
the iron to magnesia ratio (Fe:MgO) was less than ideal indicating the presence of high MgO (ultramafic minerals) suggesting more depressant to suppress rather than liberate MgO is required
-
In the case of Munda
-
rapid flotation kinetics were demonstrated
-
the concentrate was notably very clean
-
a very high Fe:MgO ratio was achieved indicating a premium concentrate
-
in light of the above, further improvements in recovery may be possible by easing back on concentrate grade
Test-work on samples from both deposits followed commercial process norms comprising a regime of sequential flotation involving a preliminary rougher product being generated with two subsequent stages of cleaning to generate a final cleaner product.
The samples of mineralised core for testing were sourced from a single diamond drill hole (WD9807W1 drilled by Western Diamond Drillers Pty Ltd in July 2018) at 132N. Diamond drill holes from Munda (EMD001 and EMD002) were drilled in July 2019 by Topdrive Drillers Australia for Estrella Resources from whom Neometals acquired the Munda nickel rights in September 2019.
Forward Work
The Company has commenced a detailed geological and geometallurgical program to ascertain the potential impacts on its eleven separately defined Mineral Resources at Mt Edwards and exploration potential within its > 300 square km tenure.
The components of the geometallurgical program include:
-
the geologically informed selection of a number of mineralised samples
-
laboratory-scale planned locked cycle test work to determine the response of the mineralisation to mineral processing unit operations
-
the distribution of these parameters throughout the deposits using an accepted geostatistical technique
-
the application of a mining plan and mineral processing models to generate a prediction of the process plant behaviour
Managing Director Chris Reed commented:
“Further to our earlier test-work at Armstrong these preliminary results confirm the presence and recoverability of palladium at 132N, some 4 km south along strike, and the eminently marketable nature of nickel products able to be generated from both 132N and Munda. Of specific note is the high-quality concentrate made from Munda, a deposit not previously exploited for its nickel endowment. This represents another positive step in the development of the Mt Edwards project”.

Background
The Mt Edwards nickel project is centred around the small township of Widgiemooltha, located 75 kilometres south of Kalgoorlie in Western Australia. Neometals owns, or holds nickel rights to, 36 mining tenements with a large land holding of more than 300km[2] across the Widgiemooltha Dome, a well-recognised nickel sulphide mining province. The Widgiemooltha Dome is a world class nickel sulphide camp that has hosted 7 historical nickel mines with a new mine, Cassini, currently under development by Mincor Resources Ltd.
Platinum and Palladium at Mt Edwards
The Mount Edwards project database consists of assay and geological data from more than 13,000 drill holes. Platinum (Pt) and Palladium (Pd) have been sparingly assayed in work to date at Mount Edwards. While the majority of samples have been assayed for nickel or lithium, only ~10% (42,468 of 422,129) of the total samples have been assayed for either Pt or Pd. Historically Pt and Pd assays were used as an indicator element in exploration activities helping to vector in on new discoveries.
Nickel mining at the Mt Edwards project was last conducted some 13 years ago. Armstrong and 132N are on granted mining leases (M15/99 & M15/101 respectively) and are currently on ‘care and maintenance’ status with the Department of Mines and Petroleum. Since previous production the price of palladium has increased markedly with a tenfold increase in value since 2008. The significance of the increased market value of palladium and platinum, coupled with a positive result from early-stage sighter metallurgical test work, now warrants further investigation to determine if these precious metals can provide an additional revenue stream for the nickel project.

APPENDIX 1: Table 1 as per the JORC Code Guidelines (2012) 132 N
| Section 1 Sampling Techniques and Data | 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 sondes, or handheld XRF instruments, etc). These examples should not be taken as limiting the broad meaning of sampling which includes reference to measures taken to ensure sample representivity and the appropriate calibration of any measurement tools or systems used. Aspects of the determination of mineralisation that are Material to the Public Report. In cases where ‘industry standard’ work has been done this would be relatively simple (e.g. ‘reverse circulation drilling was used to obtain 1 m samples from which 3 kg was pulverised to produce a 30 g charge for fire assay’). In other cases more explanation may be required, such as where there is coarse gold that has inherent sampling problems. Unusual commodities or mineralisation types (e.g. submarine nodules) may warrant disclosure of detailed information. |
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 This section discusses the processing on diamond core hole WD9807W1from which the metallurgy results in the report are derived. Metallurgical samples were compiled from core WD9807W1 in proportions to approximate the overall Mineral Resource grade |
| 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 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. WD9807W1 was sourced by way of standard HQ3 triple core diamond drilling. |
| 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 topreferential loss/gain of fine/coarse material. |
Sample recovery of drilling prior to 2000 is not known. No relationship between sample recovery and grade has been recognised. Core recovery from WD9807W1 was very good at over 85% for the mineralised zones. |
| 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. |

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. For WD9807W1 ½ core was submitted for assay, The remaining ½ of core for select metres has been used for the metallurgical test work that is the subject pf the repot. |

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 (e.g. standards, blanks, duplicates, external laboratory checks) and whether acceptable levels of accuracy (i.e. 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 laboratories have stringent quality control systems, ALS has ISO9002 certification. The analytical methods and detection limits used didn’t alter between drill methodologies. Analytical methods and detection limits are merged into the database assay file. For analysis undertaken at ALS, Perth, the entire sample was prepared. Analytical schemes and detection limits as follows • ME-ICP61 (formerly IC587) four acid digestion, HF-HNO3- HCLO4 acid digestion, HCL leach and ICP - AES, detection limits in brackets. Cu (1ppm), Co (1ppm), Ni (1ppm), Cr (1ppm), As (5ppm), Mn (5ppm), Al (0.01%), S (0.01%), Mg (0.01%) and Fe (0.01%). • Copper and nickel values in excess of 1% were re assayed via analytical schemes AA46 (formerly A101) and AA62 (formerly A102) with lower detection limits of 0.01%. |

Assay, Sample ID and logging data of the historical databases are matched and validated using filters in the drill database. The data is further visually validated by Neometals geologists and database staff. There has been no validation and cross checking of laboratory performance at this stage. No adjustments have been made to 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. 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 |

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 most samples within geological zones sampled at 1m lengths. |

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 for the Mineral Resource due to drilling orientation. Orientation of drilling forWD9807W1 was down dip at approximately 30oto the orientation to maximise mineralised samples for metallurgical test work. |

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. Neometals (and contractors for Neometals) drilled, sampled and assayed WD9807W1. |
| 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. |

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. |
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 (e.g. cutting of high grades) and cut-off grades are usually Material and should be stated. Where aggregate intercepts incorporate short lengths of high grade results and longer lengths of low grade results, the procedure used for such aggregation should be stated and some typical examples of such aggregations should be shown in detail. The assumptions used for any reporting of metal equivalent values should be clearly stated. |
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 (e.g. ‘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. |
| 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. |
| Further work | The nature and scale of planned further work (e.g. 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. |
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. |
| The use of geology in guiding and controlling Mineral Resource estimation. The factors affecting continuity both of grade and geology |
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 mineralised zones resulting in three discrete domains. |
|
| Dimensions | The extent and variability of the Mineral Resource expressed as length (along strike or otherwise), plan |
The modelled 132N deposit has a strike extent of 1,500m and a vertical down dip extent of about 450m. The mineralised |
| width, and depth below surface to the upper and lower limits of the Mineral Resource. |
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 (e.g. 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. |
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. |

The process of validation, the checking process used, the comparison of model data to drill hole data, and use of reconciliation data if available. |
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 in the 132N Mineral Resource estimate. Modelling only extended to the top of fresh rock to ensure only sulphide nickel mineralisation was estimated. Subsequent to the Mineral Resource estimate test work including a flotation program on core from 132N yielded 62.8% recoveryat 13.5% nickel concentrategrade. |
| 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 considered this should be reported with an explanation of the environmental assumptions made. |
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 Mineral Rsources 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 |

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. |

• This section discusses the processing on diamond core holes EMD001 and EMD002, from which the metallurgy results in the report are derived. • Diamond HQ core was collected, meter marked and logged for lithology and mineralogy. Soft oxide/clay zone samples were manually split in the trays and half the core sampled for assaying. Competent core in the transitional and fresh zones was orientated and ¼ core cut using an Almonte Automatic core saw. The right hand upper ¼ core piece was constantly taken for assay analysis, enabling consistency of representative sample collection. The left-hand side of the ¼ core was retained in the core trays for future reference and the remaining ½ core also retained in the core trays for future resampling, relogging, analysis or test-work. • No other measurement tools have been used in the holes other than directional/orientation survey tools. • Core was meter marked according to the drillers blocks and adjusted where core loss was recorded. Down hole orientation directions were recorded and marked along length of competent core. • Determination of mineralisation has been based on geological logging including mineral identification, with confirmation using a pXRF machine. Core samples were dispatched for laboratory analysis and reported to NATA & JORC code standards. • Determination of mineralisation via laboratory assay results is considered mineralised with samples returned above 5000ppm (0.5%) Ni and or 0.5ppm Au. |

• 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. |
• Soft oxide/clay zone samples were manually split in the trays and half the core sampled for assaying. Competent core in the transitional - fresh zone was orientated, and ¼ core cut using an Almonte Automatic core saw. The right hand upper ¼ core piece was constantly sampled for assay analysis. The left-hand side was retained in the core trays for future reference and the remaining ½ core available for resampling. • The sample preparation technique is considered industry best standard practice and was completed by the geologist. • Standard reference material and duplicate ¼ core samples were inserted into the sample stream at a nominal 25 metre intervals to determine laboratory cleanliness and repeatability. • Core samples intervals were selected between 25cm to 1m widths and cut for sampling. Samples in the unmineralised lower portion of EMD002 were sampled as 2m composite (1/4 core) intervals from 114m-170m. • Sample intervals were based on either geological boundaries or meter mark intervals. • Quarter HQ core provides sufficient sample volume to reduce variation as a result of the grain size of the mineralisation. • Metallurgical samples were compiled from EMD001 and EMD002 to reflect the overall resource head grade |
| Quality of assay data and laboratory tests |
• For geophysical tools, spectrometers, handheld XRF instruments, etc, the parameters used in determining the analysis including instrument make and model, reading times, calibrations factors applied and their derivation, etc. • Nature of quality control procedures adopted (e.g. standards, blanks, duplicates, external laboratory checks) and whether acceptable levels of accuracy (i.e. lack of bias) and precision |
• No results from geophysical tools are being reported. • No handheld XRF results are reported however the tool was used to verify the mineralisation with reporting >0.4% Ni in disseminated zones and >1% Ni in the matrix sulphide zones. • Assaying was completed by a commercial registered laboratory with internal blanks, standards and duplicates reported in the sample batches. In addition, gold and base metal Standard Reference samples were inserted into the batches by the geologist. Duplicate ¼ core sample were also inserted into the sample stream. |

Section 2 Reporting of Exploration Results
| Section 2 Reporting of Exploration Results | Section 2 Reporting of Exploration Results | Section 2 Reporting of Exploration Results |
|---|---|---|
| Criteria | JORC Code explanation | Commentary |
| Exploration done by other parties |
• Acknowledgment and appraisal of exploration by other parties. |
• Exploration has been undertaken by previous holders, but predominantly Western Mining Corporation (WMC) during the 1980s, Resolute Gold in the 1990’s and Titan Resources from 2001. Consolidated Minerals took ownership from Titan in 2006, and Salt Lake Mining in 2008 |
| Geology | • Deposit type, geological setting and style of mineralisation. |
• The geology at Munda consists of a mafic-ultramafic belt bound to the west by metasediments and to the east by granites • The mineralisation at Munda consists of structurally controlled quartz veins and pegmatite bodies located in a mafic-ultramafic package. • Depth of complete oxidation varies from 10 to 80 metres below the natural surface but is typically around 40-50m metres in depth. |
| Drill hole Information |
• A summary of all information material to the understanding of the exploration results including a tabulation of the following information for all Material drill holes: oeasting and northing of the drill hole collar oelevation or RL (Reduced Level – elevation above sea level in metres) of the drill hole collar odip and azimuth of the hole odown hole length and interception depth ohole length. • If the exclusion of this information is justified on the basis that the information is not Material and this exclusion does not detract from the understanding of the report, the Competent Person should clearly explain why this is the case. |
• All relevant drillhole information can be found in Appendices 2 & 3. • No information is excluded. |
| Data aggregation methods Data aggregation methods cont. |
• In reporting Exploration Results, weighting averaging techniques, maximum and/or minimum grade truncations (e.g. cutting of high grades) and cut-off grades are usually Material and should be stated. • Where aggregate intercepts incorporate short lengths of high-grade results and longer lengths of low grade results, the procedure used for such aggregation should be stated and some typical examples of such aggregations should be shown in detail. |
• Intersections are reported on a nominal 0.3% Ni cut-off with length weighted intervals. • Length weighted aggregations have been reported using excel SumProduct averaging to correctly calculate the effects of short high-grade samples. • SG of the mineralised samples has not been considered in determining significant intercepts |
| • The assumptions used for any reporting of metal equivalent values should be clearly stated. |
• No metal equivalents are used in this announcement. |
|
| Relationship between mineralisation widths and intercept lengths |
• These relationships are particularly important in the reporting of Exploration Results. • If the geometry of the mineralisation with respect to the drill hole angle is known, its nature should be reported. • If it is not known and only the down hole lengths are reported, there should be a clear statement to this effect (e.g. ‘down hole length, true width not known’). |
• Drilling is orientated for the gold bearing vein sets and is at ~45 degree to the ultramafic contact and the nickel sulphide mineralisation • It is expected that true width of the nickel enriched zones will be approximately 60% of the reported significant intercepts. A more complete picture of the width of mineralisation and will be accurately calculated once structural interpretations and orientations are completed. |
| 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. |
|
| 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. |
• All new drill holes are reported in Appendix 2 & 3 below • All nickel results within the mineralised zones have been reported including internal dilution and samples either side of the zone. Multiple element data other than relevant to Nickel has not been reported as the data is extensive and is not important to the economic value. |
| Other substantive |
• Other exploration data, if meaningful and material, should be reported including (but |
• Everything meaningful and material is disclosed in the body of the report. |
