From 26.0 Millon tonne (Mt) (Indicated) to 81.3 Mt @ 3.16% Total Heavy Mineral (THM)
-
Indicated Mineral Resource 75.5 Mt @ 3.17% THM
-
Inferred Mineral Resource 5.7 Mt @ 3.06% THM
-
-
The additional Area 2 MRE lifts the Company’s total inventory tonnage by 6% to 892.1 Mt.
VHM Limited (“VHM” or the “Company”) is pleased to provide an update on the Goschen Project's EES approvals progress and to provide an updated Inferred and Indicated MRE of 81.3 Mt @ 3.16% THM grade containing 2.6 Mt of in-situ Heavy Mineral Sands (HMS) in Area 2.
Goschen Approvals Update
The Directions Hearing for the Goschen Project’s EES approvals process was held on Tuesday, 13 February 2024. The independent Inquiry and Advisory Committee (IAC) appointed by the Victorian Planning Minister informed the representing parties of the agenda, and duration for the Public Hearing stage.
The Public Hearing stage commenced on Monday 25 March 2024 and will conclude on Tuesday 30 April 2024.
Upon completion of the Public Hearing the IAC has 40 business days to provide the Victorian Planning Minister with a recommendation on the Goschen Project.
AREA 2 Mineral Resource Estimate
The Area 2 MRE crosses over the Company’s retention licence (RL) 6806 and exploration licence (EL) 6419 (Figure 1). Area 2 was previously classified into two areas - Area 2 West, and Area 2 East with amalgamation of the two zones to form Area 2 for the Mineral Resource estimation.
Area 2 is located 3.5 kilometres (km) north west of the base plant (Area 1) for the proposed Goschen Rare Earths and Mineral Sands Project (Goschen).
The Mineral Resource estimate contains 65,000 tonnes of rare earths (TREO+Y), 0.5 Mt of zircon, 0.3 Mt of rutile and 0.2 Mt of leucoxene and increases the Company’s total inventory of TREO from 602,000 tonnes to 649,000 tonnes (Appendix 1, Table 1).

The MRE includes moderate to high-grade strand-like zones between 7m and 10m from surface and extends 2.6 km north-south and 3.5 km east-west and remains open in all directions.
The Area 2 West Resource was first estimated in 2019 and reported in the Company’s Prospectus 0F[1] . Area 2 East was drilled in 2019 1F[2] , however, the samples were stored and not submitted for assaying. Assay results and subsequent mineralogy composites were interpreted by independent consultant Right Solutions Australia, to combine the two adjacent resources into a single model to generate the revised and expanded resource estimate.
VHM Chief Executive Officer Ron Douglas said: “The addition of Area 2’s Mineral Resource estimate provides further upside for the Company’s Global Resources, and these results demonstrate the valuable characteristics of the rich mineralisation found in Victoria’s Murray-Darling Basin.”
“VHM’s primary focus is on taking Goschen through to development, so I am pleased the Panel Hearing for the Goschen Project’s Environment Effects Statement has now commenced and under the direction of an independent Inquiry and Advisory Committee.”

Appendix 2: Mineral Resource Estimate and Reporting Criteria
In accordance with ASX Listing Rule 5.8 (Requirements applicable to reports of Mineral Resources for material mining projects) and the 2012 JORC reporting guidelines, information material to the Area 2 Mineral Resource estimate is summarised below. More detail is provided in the JORC Code (2012 Ed.) Appendix 3, Table 1, Sections 1 to 3.
Geology and geological interpretation
Regional geological setting
The Murray Basin underlies an area of 300,000 km[2] of north-western Victoria, south-eastern South Australia and south-western New South Wales and comprises flat, late Miocene to Pliocene, Epochaged sediments (Brown & Stephenson, 1991).
Accumulations of HMS are widespread over most of the Victorian portion of the Murray Basin. The upper sequences of the Murray Basin sediments, principally the Loxton Sand (formerly known as Loxton-Parilla Sand), are known to contain economic accumulations of HMS.
The Murray Basin is a large sedimentary basin that formed by subsidence occurring at the beginning of the Tertiary period. As global sea levels rose during the middle Tertiary, the basin was flooded to form what has been named the Murravian Gulf into which HMS was deposited by several paleo-river systems. These rivers transported sediments enriched with ilmenite, rutile, zircon, monazite and xenotime derived from weathering and erosion of Palaeozoic granites of the Lachlan Fold Belt, sandstone of the Mesozoic basins and rocks of the “Great Dividing Range”.
The distribution of the mineralisation within the Loxton Sand is controlled by the paleo-location of the various deltas/discharges of the Great Darling Anabranch, the Darling River, the Murray River, the Loddon River, the Glenelg River, and possibly other paleochannels, into the Murravian Gulf. The discharges zones were possibly controlled by movement of regional faults in the Cambro-Ordovician and Ordovician-aged metasediments that form the hard-rock basement of the Murray Basin.
The Area 2 Project area is interpreted to lie west of the Avoca Fault, within the Stawell structural zones. Basement rock within the Stawell Zone comprises Cambrian to Ordovician turbidites intruded by granites. The Stawell Zone extends west from the Avoca Fault to its western limit at the Moyston Fault.
The Cannie Fault, which extends northeast-southwest east of the Project area, is a small splay fault connecting the Avoca Fault in the eastern part VHM tenements to a second, north-westerly trending splay of the Avoca Fault. The Area 2 Project lies to the west of the Cannie Fault.
The Murray Basin formed as a result of ongoing regional extension which created the relatively shallow, saucer shaped depression of the Murravian Gulf. The gulf was open to the Southern Ocean which allowed for semi-continuous marine incursions and local oscillations in shoreline position during the Tertiary Period.
The HMS mineralisation of the Murray Basin is unique to the Loxton Sand unit as a result of deposition occurring during the break-up of Gondwana in the Cretaceous Period, which allowed for a sufficiently high-energy system and large supply of sediment for the concentrated strandlines to form.
The Loxton Sand unit includes the deposits derived from the bottom of the lower shoreface facies and the upper shoreface facies, i.e. the finer sand and silt deposited beyond the high-energy beach zone; the very coarse material from the breaker zone; the well-sorted, medium-grained material from the swash zone; and the supralittoral material, including dunes. The Bookpurnong Formation (formerly
7
the Bookpurnong beds), the Loxton Sand, and the Shepparton Formation were deposited contemporaneously and are lateral equivalents of a single “system” and, as such, it is difficult to distinguish between them in transitional zones.
The Murravian Gulf was dammed in the late Pleistocene by uplift of the Pinnaroo Block to the southwest of the depocenter of the basin. The restriction of the oceanic system changed the depositional environment of the basin to one dominated by lakes and rivers which allowed for the accumulation of fluvial sediments, primarily sand and clay. Later deposits of aeolian sand continue to cover the basin to this day.
Local geological setting
The heavy mineral sands at the Area 2 deposit are hosted within the offshore and near shore/marginal marine depositional paleo-environment of the Loxton Sands. The grain size of the Loxton Sands generally decreases with depth within Area 2. Five main strandlines have been interpreted in the middle to upper portions of the Loxton Sands and four sheet-like horizons of mineralisation within the lower portions of the Loxton Sands. The strandlines are known to develop by reworking of coastal sediments because of wave action while sheet deposits are associated with near-shore sediments.
Area 2 was previously classified into two areas, Area 2 West and Area 2 East with amalgamation of the two zones to form Area 2 during the mineral resource estimation.
Sampling and subsampling techniques
Drill samples were obtained at 1 m intervals generating approximately 8 kg of drill spoil that was then split down to approximately ~1200 to ~2500g by a riffle splitter for export to the primary analytical laboratory. The sub-split samples were labelled and bagged for transport to the primary laboratory for processing. All sample intervals and the correlating sample numbers were recorded digitally directly into the Company’s database.
The sampling method and sample size dispatched for processing is considered appropriate and reliable based on accepted industry practices and experience.
Drilling techniques
All drillhole and assay data were extracted from VHM’s MX Deposit database where it had been validated and stored to maintain data security.
A multi-staged drill program of 256 drillholes was conducted between March 2017 and April 2019 to determine the mineralisation within Area 2. Drilling was carried out by Wallis Drilling using a Mantis 80 mounted on a custom Land Cruiser six-wheel drive. Reverse circulation aircore was used to drill the Area 2 West Goschen deposit. Aircore is considered a standard mineral sands industry technique for evaluating heavy mineral mineralisation where the sample is collected at the drill bit face and returned inside an inner tube. The drill rods are 76 mm diameter (NQ) and 3 m in length. All holes were drilled vertically with majority of the samples downhole taken at 1 m intervals.
A regular rectangular grid spacing for the Area 2 deposit was on a spacing of 400 m in the north-south direction and with 50 m and 100 m stations to the east-west direction. The 400 m x 100 m spaced aircore holes and regular grid pattern are sufficient to provide a good degree of confidence in geological models and grade continuity within the holes. The 50 m spacing is within the western side of the deposit as a result of intersecting high-grade strandlines.
8
The criteria used for classification, including drill and data spacing and distribution – this includes separately identifying the drill spacing used to classify each category of mineral resources (inferred, indicated and measured) where estimates for more than one category of mineral resource are reported
Resource classification has been completed on a zone-by-zone basis where drill spacing and assay availability for THM, mineral assemblage and chemical analysis have been considered. Predominantly an indicated resource classification is applied for the entirety of the Zone where sufficient data is available. However, in some instances varied availability of data has required single zones to have mixed classifications including both indicated and inferred. Indicated and inferred zones have been created by digitising a polygon in Datamine and coding all blocks from that zone that share XY coordinates encapsulated within the polygon.
Sample analysis method
Sample Analysis–Diamantina Assay Method (static gravity drop heavy liquid separation)
Area 2 West samples were dispatched to Diamantina Laboratories (Diamantina) which followed the general assay process flow described as follows.
-
The samples selected for assay were received by Diamantina check-in process then oven dried at approximately 110°C until samples were completely dry.
-
Samples were then rotary split down to approximately ~100 g sub-splits (weighed and captured) with one sample then submitted to screening via vibrating deck screens with the application of water.
-
Every 25th sample was submitted to the same process as a laboratory repeat.
-
The wet screens used either a top screen of 1 mm (90% of all samples from Area 2 West sent to Diamantina) or a top screen of 2mm (10% of all samples from Area 2 West sent to Diamantina) and a bottom screen of 38 μm
-
Material captured by the upper screen (OS) and 38 μm (SAND) screens was individually captured, dried and weighed, whilst material passing through the 38 μm (SLIMES) screen was lost to wastewater systems.
-
The SAND fraction was analysed by static gravity assisted Heavy Liquid Separation (HLS) using tetrabromoethane (TBE)
-
Four holes were completed with the following method however using 20 μm screens for the sand and slime fractions.
Sample Analysis–ALS Assay Method (centrifuge-assisted heavy liquid separation)
Samples were dispatched to ALS Global (ALS) Laboratories which followed the general assay process flow described as follows;
-
The samples selected for assay were received by ALS Laboratories check-in process then oven dried at approximately 110°C until samples were completely dry.
-
Samples were then riffled split down to approximately ~500 g sub-splits (weighed and captured) then soaked for 24 hours in 1% tetrasodium pyrophosphate (TSPP – a dispersing agent used to help disaggregate clays).
-
Every 25th sample was submitted to the same process as a laboratory repeat.
9
-
The wet screens used a top screen of 1 mm and a bottom screen of 20 μm. After the first screening samples were subjected to a mechanical agitation (1% TSPP) for 5 minutes then re-screened for a second time.
-
Material captured by the upper screen and 20 μm (SAND) screens was individually captured, dried and weighed, whilst material passing through the 20 μm (SLIMES) screen was lost to wastewater systems.
-
The SAND fraction (1 mm to -20 µm) was split down to approximately ~100 g sub-splits for centrifuge assisted Heavy Liquid Separation (HLS) using tetrabromoethane (TBE).
Mineral assemblage composites have been prepared for the Area 2 deposit by utilising both x-ray fluorescence (XRF), ICP-MS and QEMSCAN to define the mineralogy and chemistry as a proportion of the THM. All sample composites were selected exclusively by VHM and completed by ALS Global Perth.
-
The XRF technique provides measurements of relative elemental abundances (down to limits of a few parts per million) which allows for a quantifiable basis for determination of mineralogy, provenance, depositional environment, and diagenetic history. The XRF analysis was utilised to apply assay data to the geological model for grade interpretation.
-
The ICP-MS technique provides measurements of relative elemental abundances (down to limits of a few parts per million) that cannot be picked up using XRF techniques, which allows for a quantifiable basis for determination of mineralogy, provenance, depositional environment, and diagenetic history.
-
The QEMSCAN method of analysis, carried out using particle scale analysis, required the samples to be screened into +150 µm and -150 µm screen fraction prior to sample preparation and QEMSCAN analysis to give a quantitative understanding of the elemental composition and mineralogical assemblage. Screening the composite sample into two sub-samples, using a bottom screen of 150 µm ensures any segregation between coarse and fine particles during the setting of the resin for the polished section used for QEMSCAN analysis is managed.
Estimation methodology
A total of 256 drillholes were used for the Area 2 mineral resource estimate. Drillhole collars were all surveyed using RTK GNSS survey equipment to establish horizontal and vertical control to Map Grid of Australia Zone 54 and to the Australian Height Datum.
VHM generated a topographic DTM surface within Datamine using the surveyed drill collars from holes completed in the Area 2 Project. The generated topographic DTM surface was used for this Mineral Resource estimation.
Sampling and assaying were subjected to QAQC processes by VHM with the submission of field duplicates and standards and by ALS using internal duplicates and standards.
The rate of submission for company standards was 1:20 and for submitted field duplicates was 1:100. Field duplicates were taken at the frequency of 1:20 however due to the selective assay method, 1:100 were submitted to the laboratory. Both laboratories completed their internal QAQC checks including laboratory standards every 40th sample and a laboratory repeat every 25th sample prior to the results being released.
A majority of the standard samples submitted to the laboratory by VHM were within acceptable limits of +3SD however two standards fell outside tolerance (>3STD). These were reviewed and accepted based on surrounding standards and assays.

Ordinary Kriging estimation technique was used to interpolate THM, Slimes and OS grades from drill samples into the block model. Nearest neighbour techniques were used to interpolate mineral assemblage, rare earth elements, index values and non-numeric sample identification into the block model.
The mostly regular dimensions of the drill grid and the anisotropy of the drilling and sampling grid allowed the use of ordinary kriging and nearest neighbour methodologies as no de-clustering of samples was required.
Appropriate search ellipses were used to search for data for the interpolation and suitable limitations on the number of samples and the impact of those samples was maintained. The minor direction of 0.5 remained constant for all four search passes to control the distribution of grade in the vertical extent. Each zone was estimated with a directional search ellipse with varying search ranges over three search passes. The minimum number of samples required was three and the maximum was 16.
Area 2’s Mineral Resource estimate bulk density formula is described as:
- Bulk Density = (0.009 * THM) + 1.698.
It is believed that the bulk density applied the MRE is conservative and fit for purpose at this level of confidence for the MREs and in line with VHM’s Area 1 MRE.
Cut-off grade(s), including the basis for the selected cut-off grade(s)
Grade cutting or capping was not used during the interpolation because of the regular nature of sample spacing and the fact that samples were not clustered nor wide spaced to an extent where elevated samples could have a deleterious impact on the resource estimation. Sample distributions were reviewed, and no extreme outliers were identified either high or low that necessitated any grade cutting or capping.
Cut-off grade for TVHM (THM x VHM) was used to prepare the reported resource estimates. A 1% TVHM cut-off grade was selected for reporting the resource estimate following visual validation through spatial positioning of the grade interpolation at varying cut-offs and is in line with the previous IHC Robbins 2019 MRE for Area 2 West. The reporting of the Indicated and Inferred Mineral Resource refers to a global estimate for the Area 2 deposit.
Mining and metallurgical methods and parameters, and other material modifying factors considered to date
No specific mining method is assumed other than potentially the use of dry mining methods.

Appendix 3 – Area 2 - JORC Table 1 (JORC Code, 2012 Edition)
Section 1: Sampling Techniques and Data
(Criteria in this section apply to all succeeding sections)
| Criteria | JORC Code Explanation | Commentary |
|---|---|---|
| Sampling techniques |
• Nature and quality of sampling (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. • 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 (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. |
Aircore drilling, commenced on 25 November 2017 and completed on 2 April 2019, was used to obtain 1m sample intervals. The following information covers the sampling process: •each 1 m sample is homogenized within the bag by manually rotating the sample bag. •The large 1m Aircore drill samples were split down to approximately ~1000 to ~2500g by rotary splitter for export to the primary analytical laboratory. •a sample of sand, approximately 20g, is scooped from the sample bag for visual THM% and SLIMES% estimation and logging. The same sample mass is used for every pan sample for visual THM% and SLIMES% estimation. •The standard sized sample of approximately 20g is to ensure calibration is maintained for consistency in visual estimation. •Downhole geophysical surveys were conducted to utilise gamma signatures for ascertaining mineralisation zones within the lithological sequence. •Duplicates were taken at the drill rig from side‐by‐side sample locations at a rate of ~1 in 20. •Duplicates were taken within mineralisation zones as the waste material was excluded from sampling. •Commercially obtained standards were inserted by the laboratory at a rate of ~ 1 in 40. •The laboratory sample was oven dried at 105 degrees for a minimum of 2 hours (and then redried for up to 12 hours if required), and split down to 100 g sub samples via a rotating splitter fed by a vibrating screen. A laboratory repeat was taken at ~ 1 in 25 samples. Area 2 West samples were dispatched to Diamantina Laboratories, Perth. The following information covers the sampling process at Diamantina: •All drill hole sub‐samples were screened using vibrating screens with a top screen of 2 mm and a bottom screen of 38 μm. Oversize (+2 mm fraction) was removed and‐38 μm fraction (SLIMES) discarded. The sand fraction (2 mm to +38 μm) was then submitted for heavy liquid separation using TBE to determine total heavy mineral content. Area 2 East samples were dispatched to ALS Global Laboratories, Perth. The following information covers the sampling process at ALS: •All drill hole sub‐samples were screened using vibrating screens with a top screen of 1 mm and a bottom screen of 20 μm. Oversize (+1 mm fraction) was removed and‐20 μm fraction (SLIMES) discarded. The sand fraction (1 mm to +20 μm) was then submitted for heavy liquid separation using TBE and centrifuge assist to determine total heavy mineral content. |
12
| 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.). |
Wallis Drilling was the contractor used for the drilling programs that support the Area 2 Mineral Resource estimate. Aircore drilling with inner tubes for sample return was used. Aircore is considered a standard industry technique for Heavy Mineral Sand (HMS) mineralisation. Aircore drilling is a form of reverse circulation drilling where the sample is collected at the face and returned inside the inner tube. Aircore drill rods used were 3 m long. NQ diameter (76 mm) drill bits and rods were used. All drill holes were vertical. |
|---|---|---|
| Drill sample recovery |
• Method of recording and assessing core and chip sample recoveries and results assessed. • Measures taken to maximise sample recovery and ensure representative nature of the samples. • Whether a relationship exists between sample recovery and grade and whether sample bias may have occurred due to preferential loss/gain of fine/coarse material. |
Drill sample recovery is monitored by recording sample condition from ‘dry good’ to ‘wet poor’. While initially collaring the hole, limited sample recovery can occur in the initial 0m to 1m sample interval owing to sample and air loss into the surrounding loose soil. The initial 0 m to 1 m sample interval is drilled very slowly in order to achieve optimum sample recovery. The entire 1m sample is collected at the drill rig with the primary split at the drill rig using the rotary splitter attached to the base of the cyclone. The coarse reject is retained. At the end of each drill meter and drill rod, the drill string is cleaned by blowing down with air to remove any clay and silt potentially built up in the sample tubes. The twin-tube aircore drilling technique is known to provide high quality samples from the face of the drill hole (in ideal conditions). |
| 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. • |
The 1m aircore samples were each qualitatively logged via digital entry using into a Microsoft Excel spreadsheet, and later uploaded into an Acquire Database. VHM change database providers in Q1 2023 to MXDeposit. All past logging data is now stored in the MXDeposit database. The aircore samples were logged for lithology, colour, grainsize, sorting, hardness, sample condition, washability, estimated THM%, estimated SLIMES% and any relevant comments such as slope, vegetation, or cultural activity. Every drill hole is logged in full. Logging is undertaken with reference to a Drilling Guideline with codes prescribed and guidance on description to ensure consistent and systematic data collection. |
| Sub- sampling techniques and sample preparation |
• If core, whether cut or sawn and whether quarter, half or all cores 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 |
The 1 m sample interval is rotary split at the drill rig, collected and dispatch to Diamantina laboratories and ALS Global laboratories. The water table depth was noted in all geological logs if intersected whereby sample condition was specified as ‘wet poor’. A total of ~1.2 kg to ~2.5 kg of each sample was placed into calico sample bags and exported to Diamantina Laboratories or ALS Global Laboratories for THM analysis. Almost all of the samples are silty sand, sandy clay, clayey sand, sandy clay or clay and this preparation method is considered appropriate. The sample sizes were deemed suitable to reliably capture THM, slime, and oversize characteristics, based on industry experience of the geologists involved and consultation with laboratory staff. |
13
| for instance results for field duplicate/second-half sampling. • Whether sample sizes are appropriate to the grain size of the material being sampled. |
Field duplicates of the samples were completed at a frequency of 1 per 20 primary samples in the field. |
|
|---|---|---|
| Quality of assay data and laboratory tests |
• The nature, quality and appropriateness of the assaying and laboratory procedures used and whether the technique is considered partial or total. • 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. |
The wet panning at the drill site provides an estimate of the THM% which is sufficient for the purpose of determining approximate concentrations of THM in the first instance. Area 2 West samples were dispatched to Diamantina Laboratories (static gravity drop heavy liquid separation) which followed the general assay process flow described as follows: •The samples selected for assay were received by Diamantina check-in process then oven dried at approximately 110°C until samples were completely dry •Samples were then rotary split down to approximately ~100 g sub-splits (weighed and captured) with one sample then submitted to screening via vibrating deck screens with the application of water •Every 25th sample was submitted to the same process as a laboratory repeat •The wet screens used either a top screen of 1 mm (90% of all samples from Area 2 West sent to Diamantina) or a top screen of 2mm (10% of all samples from Area 2 West sent to Diamantina) and a bottom screen of 38 μm •Material captured by the upper screen (OS) and 38 μm (SAND) screens was individually captured, dried and weighed, whilst material passing through the 38 μm (SLIMES) screen was lost to wastewater systems. •The SAND fraction (1 mm to -38 µm) was split down to approximately ~100 g sub-splits for static gravity assisted Heavy Liquid Separation (HLS) using tetrabromoethane (TBE) •The laboratory used TBE as the heavy liquid medium – with density range between 2.92 and 2.96 g/ml •Four holes were completed with the following method however using 20 μm screens for the sand and slime fractions. Samples were dispatched to ALS Global Laboratories (centrifuge-assisted heavy liquid separation) which followed the general assay process flow described as follows; •The samples selected for assay were received by ALS Laboratories check-in process then oven dried at approximately 110°C until samples were completely dry. •Samples were then riffled split down to approximately ~500 g sub-splits (weighed and captured) then soaked for 24 hours in 1% tetrasodium pyrophosphate (TSPP – a dispersing agent used to help disaggregate clays) •Every 25th sample was submitted to the same process as a laboratory repeat. •The wet screens used a top screen of 1 mm and a bottom screen of 20 μm. After the first screening samples were subjected to a mechanical agitation (1% TSPP) for 5 minutes then re-screened for a second time •Material captured by the upper screen and 20 μm (SAND) screens was individually captured, dried and |
14
| weighed, whilst material passing through the 20 μm (SLIMES) screen was lost to wastewater systems. •The SAND fraction (1 mm to -20 µm) was split down to approximately ~100 g sub-splits for centrifuge assisted Heavy Liquid Separation (HLS) using tetrabromoethane (TBE) •The laboratory used TBE as the heavy liquid medium – with density range between 2.92 and 2.96 g/ml •Field duplicates of the samples were completed at a frequency of 1 per 20 primary samples in the field however 1 per 100 samples were submitted for assay due to the selective assay method. Both Laboratories completed their own internal QA/QC checks that included laboratory standards every 40th sample and a Laboratory repeat every 25th sample prior to the results being released. VHM standards were inserted at a frequency of 1 per 20 samples. Analysis of QAQC samples shows the laboratory data to be of acceptable accuracy and precision. |
||
|---|---|---|
| Verification of sampling and assaying |
• The verification of significant intersections by either independent or alternative company personnel. • The use of twinned holes. • Documentation of primary data, data entry procedures, data verification, data storage (physical and electronic) protocols. • Discuss any adjustment to assay data. |
All results are checked by the company’s Geology Manager Two twinned holes have been drilled in Area 2 East (A2E) No adjustments have been made to the assay data received from Diamantina and ALS Global. Assays were imported into the MXDeposit database. Field and laboratory duplicate data pairs (THM/OS/SLIME) of each batch are plotted to identify potential quality control issues. Standard Reference Material sample results are checked from each sample batch to ensure they are within tolerance (<3SD) and that there is no bias. •Two standards fell outside tolerance (>3STD). These were reviewed and accepted based on surrounding standards and assays. The field and laboratory data were exported from the VHM database and imported into Datamine by Right Solutions. Data validation criteria are included to check for overlapping sample intervals, end of hole match between ‘Lithology’, ‘Sample’, ‘Survey’ files and other common errors. |
| 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. |
Down hole geophysical surveys were conducted to utilise gamma signatures for ascertaining mineralisation zones within the lithological sequence. Drill hole collars were surveyed by an independent survey company using industry standard equipment. Three permanent survey marks in the area assisted with the collar pickups, allowing for consistent survey readings across the Project. The datum used is GDA 94 and coordinates are projected as MGA zone 54. A digital topographic surface was generated by VHM Limited from data collected during a LIDAR survey commissioned by VHM. The accuracy of the locations is sufficient for this stage of exploration. |
| 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 |
A regular rectangular ~400m x ~100m grid spacing is dominant at the Area 2 Project with a tighter drill spacings of ~400m x ~50m on seven drill lines in Area 2 West The company has completed 256 drill holes between 2017 and 2019 to determine the mineralisation potential at Area 2 (RL6806 and EL6419) |
15
| estimation procedure(s) and classifications applied. • Whether sample compositing has been applied. |
The 400m x 100m spaced aircore holes and regular grid are sufficient to provide a good degree of confidence in potential future geological models at this stage. The 50m spacing on the five drill lines aims to further confirm the potential continuity across strike. Each aircore drill sample is a single 1m sample of sand intersected down the hole. No down hole compositing has occurred for Total Heavy Mineral (THM) analysis. Sample composites for QEMScan analysis, submitted to ALS Global Perth, were completed on mineralised zones utilising the sinks from the THM analysis. Composite intervals were selected based on THM grades and lithology boundaries. |
|
|---|---|---|
| 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. |
The aircore drilling was oriented perpendicular to the strike of potential mineralisation as defined by previous historical drill data information. The strike of the potential mineralisation, based on observations using geology logging, down hole geophysical surveys and proximity to existing deposits define by the company, is northwest-southeast. All drill holes were vertical, and the orientation of the potential mineralisation is relatively horizontal. The orientation of the drilling is considered appropriate for testing the lateral and vertical extent of potential mineralisation without anybias. |
| Sample security |
• The measures taken to ensure sample security. |
Air core samples are stored on site (in the paddock on pallets). The samples were then dispatched to Perth using Swan Hill Freight agents and delivered directly to Diamantina laboratory. The laboratory inspected the packages and did not report tampering of the samples. Area 2 East samples stored until analysis; these were delivered to the company’s storage facility in Perth. |
| Audits or reviews |
• The results of any audits or reviews of sampling techniques and data. |
Internal reviews were undertaken during the geological interpretation and throughout,the modelling process. |
Section 2 Reporting of Exploration Results
(Criteria listed in the preceding section also apply to this section)
| Criteria | JORC Code Explanation | Commentary |
|---|---|---|
| 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. |
The exploration work was completed on tenements that are 100% owned by VHM Limited in Victoria, Australia. The drill samples for this Mineral Resource estimate were taken from tenements RL6806 and EL6419. |
| Exploration done by other parties |
• Acknowledgment and appraisal of exploration by other parties. |
Historic exploration work was completed by previous exploration companies including Austiex (1977 - 1978), CRA Exploration (1981 - 1987), Renison Goldfields Consolidated (1980 - 1991), W J Holdings (1998), RZM Group (1999), Basin Minerals (2001), Providence Gold and Minerals (2004 – 2005), and Iluka (2009). The Company has obtained the hardcopy reports and maps in relation to this information as part of its |
16
| historical review in preparation for their current work program. The historic data comprises surface sampling, limited aircore drilling and mapping. The historic results are not reportable under JORC 2012. |
||
|---|---|---|
| Geology | • Deposit type, geological setting, and style of mineralisation. |
The heavy mineral sands as defined at the Area 2 Project is a fine-grained deposit hosted within the offshore depositional paleo-environment of the Loxton Parilla Sands. The relatively strong presence of Leucoxene could indicate a reworking process for the deposit or weathering overprint. The Loxton Parilla Sand is prevalent within the Murray Basin for hosting mineral sand deposits. The Shepparton Formation clays are positioned above the Loxton Sands and the Bookpurnong Formation consisting of shallow marine clays and marls is positioned below within the lithological sequence. |
| 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. |
All relevant drill hole information is reported regarding the drilling programs completed between 25th November 2017 and 2ndof April 2019 Hole collars were surveyed by an independent surveyor using industry standard equipment. Holes were drilled vertically. Drill hole depth cross verified with drilling reports and geologist log for each hole. All relevant drill hole data is reported associated with the model build |
| 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. |
No data aggregation methods were utilised, all samples were completed on 1m down hole intervals, no top cuts were employed, and all cut-off grades have been reported. Total Valuable Heavy Mineral (TVHM >1%) was used to provide cut-off grades for reporting. TVHM is calculated by THM * VHM. |
| 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. |
The nature of the potential mineralisation is broadly horizontal, thus vertical aircore holes are thought to represent close to true thicknesses of the mineralisation. Downhole widths are reported. |
17
| • 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’). |
||
|---|---|---|
| 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. |
Refer to Figure 2, Figure 9 and Figure 12 in the main 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. |
All exploration results reported as part of the Area 2 drilling program representing both low- and high- THM results to ensure representative reporting of data. |
| 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. |
Detailed mineral assemblage work was undertaken on composite samples for the Project by ALS Metallurgy Services, Perth. ALS applied an integrated mineralogical approach using both XRF Analysis (XRF) and Quantitative Evaluation of Minerals by Scanning Electron Microscopy (QEMSCAN). This was to gain a quantitative understanding of the elemental composition and mineralogical assemblage. The XRF technique provides measurements of relative elemental abundances (down to limits of a few parts per million) which allows for a quantifiable basis for determination of mineralogy, provenance, depositional environment, and diagenetic history. The XRF analysis was utilised to apply assay data to the geological model for grade interpretation. The QEMScan method of analysis required the samples to be screened into +150 μm and‐150 μm screen fraction prior to sample preparation and QEMScan analysis. Sample preparation required each sup‐sample was mixed with size‐graded, high purity graphite to ensure particle separation and discourage density segregation. These sample‐graphite mixtures were then set into moulds using a two‐part epoxy resin, producing a representative sub‐sample of randomly orientated particles. Once cured, the resin blocks were then cut to expose a fresh surface which is then gradually ground and polished. Once QA/QC checks are completed the sections are then carbon coated for electron beam conductivity and presented to QEMScan for analysis. The samples were analysed using QEMScan technology in Field Scan Mode (FS) and Particle Mineralogical Analysis (PMA) mode. •A total of 39 mineral assemblage composites were used to characterise the mineralogy and chemistry for the deposit. •Once all of the sample compositing was completed, the sample identification and mineral assemblage composite number was submitted to Dorrit deNooy at ALS in Perth, Australia for sample collation and processing. •Preparing the mineral assemblage composites in thismannerallowsforcompositeresults to be |
18
| applied to the resource block model and for those results to then be reported and weighted on THM in the final Mineral Resource estimate. Details of summary drill hole mineral assemblage composite IDs and associated results are presented in Appendix 6. |
||
|---|---|---|
| Further work | • The nature and scale of planned further work (e.g. tests for lateral extensions or depth extensions or large-scale step-out drilling). • Diagrams clearly highlighting the areas of possible extensions, including the main geological interpretations and future drilling areas, provided this information is not commercially sensitive. |
Mix sample support occurs across Area 2 West and Area 2 East, further HLS analysis on Area 2 West samples using -1mm to +20µm sand fraction with centrifuge assist is recommended. Additional sample composites for QEMScan, XRF and ICP-MS analysis across zones with limited data. |
Section 3 Estimation and Reporting of Mineral Resources
(Criteria listed in section 1, and where relevant in section 2, also apply to this section.)
| Criteria | JORC Code Explanation | Commentary |
|---|---|---|
| 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. |
Exploration data provided by the company to Right Solutions in the form of CSV files exported from an MXDeposit database. The company provided CSV file for the down hole geophysical data for the 2019 drill program. Checks of data by visually inspecting on screen (to identify translation of samples), duplicate was visually examined to check the reproducibility of assays. Database assay values have been subjected to random reconciliation with laboratory certified value is to ensure agreement. Visual and statistical comparison was undertaken to check validityof results. |
| 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. |
No site visits were undertaken by the Competent Person during drilling as drilling was completed prior to their appointment. |
| 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. |
The geological interpretation was undertaken by Right Solutions in collaboration with the company’s Managing Director and then validated using all logging and sampling data and observations. Current data spacing and quality is sufficient to indicate grade continuity. Interpretation of modelling domains was completed across the entire sedimentary package utilising THM, Oversize, slimes, geological logging, down hole gamma signatures. The Mineral Resource estimate was controlled by geological wireframes and surfaces. |
| 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 Mineral Resource field for the project is approximately 4km in the north-south direction and 3.2 km wide in the east-west direction. It is approximately 15-20 m thick and buried by an average of 14 m of overburden. |
19
| Estimation and modelling techniques |
• The nature and appropriateness of the estimation technique(s) applied and key assumptions, including treatment of extreme grade values, domaining, 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 MRE was conducted using Datamine Studio RM Pro. Ordinary Kriging estimation technique was used to interpolate THM, Slimes and OS grades from drill samples into the block model. Nearest neighbour techniques were used to interpolate mineral assemblage, rare earth elements, index values and non-numeric sample identification into the block model. The mostly regular dimensions of the drill grid and the anisotropy of the drilling and sampling grid allowed the use of ordinary kriging and nearest neighbour methodologies as no de-clustering of samples was required. Appropriate search ellipses were used to search for data for the interpolation and suitable limitations on the number of samples and the impact of those samples was maintained. Each zone was estimated with a directional search ellipse with varying search ranges over three search passes. Hard domain boundaries were used in the interpolation of grade for each zone. The average parent cell size used for the interpolation was approximately a quarter of the standard drill section line spacing. Parent cell size used is 25mE x 100mN x 1mRL. No assumptions were made regarding the modelling of selective mining units; however, it is assumed that a form of dry mining will be undertaken. Any other mining methodology will be more than adequately catered for with the parent cell size that was selected for the modelling exercise. Sub-cell dimensions are a factor of the parent cell size using the ratios of 4 x 4 x 5. No assumptions were made about correlation between variables. Grade cutting or capping was not used during the interpolation because of the regular nature of sample spacing and the fact that samples were not clustered nor wide spaced to an extent where elevated samples could have a deleterious impact on the resource estimation. Sample distributions were reviewed, and no extreme outliers were identified either high or low that necessitated any grade cutting or capping. The sample length of 1 m does result in a degree of grade smoothing also negating the requirement for grade cutting or capping. Validation of grade interpolations were done visually in Datamine software by loading model and drillhole files and annotating and colouring and using filtering to check for the appropriateness of interpolations. Statistical distributions were prepared from drillhole and model files to compare the effectiveness of the interpolation for estimated zones. Along-strike, across-strike and vertical distributions of section line averages (swath plots) for drillholes and models were also prepared for comparison purposes. |
|---|---|---|
| Moisture | • Whether the tonnages are estimated on a dry basis or with natural moisture, and the method of determination of the moisture content. |
Tonnages were estimated on an assumed dry basis. |
20
| Cut-off parameters |
• The basis of the adopted cut-off grade(s) or quality parameters applied. |
Cut-off grade for TVHM (THM x VHM) was used to prepare the reported resource estimates. A 1% TVHM cut-off grade was selected for reporting the resource estimate following visual validation through spatial positioning of the grade interpolation at varying cut-offs and is in line with the previous IHC Robbins 2019 MRE for Area 2 West. |
|---|---|---|
| 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. |
No specific mining method is assumed other than potentially the use of dry mining methods. |
| 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. Where this is the case, this should be reported with an explanation of the basis of the metallurgical assumptions made. |
Metallurgical assumptions were used based on mineral assemblage composites which at this stage only allow for preliminary commentary with no final products being defined from the reported mineral species. Some chemistry in the form of oxides from XRF analysis was available for commentary however may not bear exact reconciliation with eventual final products. No recoveries were used or accounted for in the reporting of the MRE. |
| 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 assumptions have been made regarding possible waste and process residue; however, disposal of by products such as SLIMES, sand and oversize are normally part of capture and disposal back into the mining void for eventual rehabilitation. This also applies to gangue mineral products recovered and waste products recovered from metallurgical processing of heavy mineral. |
| Bulk density | • Whether assumed or determined. If assumed, the basis for the assumptions. If determined, the method used, whether wet or dry, |
Area 2 MRE bulk density formula is described as: Bulk Density = (0.009 * THM) + 1.698. |

| 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. |
It is believed that the bulk density applied the MRE is conservative and fit for purpose at this level of confidence for the MREs. |

|---|---|---|
| Classification | • The basis for the classification of the Mineral Resources into varying confidence categories. • Whether appropriate account has been taken of all relevant factors (ie 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). • Whether the result appropriately reflects the Competent Person’s view of the deposit. |
The resource classification for the Area 2 deposit was based on the following criteria: drill hole spacing, geological, grade continuity and estimated search pass. The classification of the indicated and inferred Mineral Resource was supported by all of the criteria as noted above. Historic drilling assay data was not included in the Area 2 MRE. The Competent Person considers that the result appropriately reflects a reasonable view of the deposit categorisation. |
| Audits or reviews |
• The results of any audits or reviews of Mineral Resource estimates. |
No audits of the mineral resource estimate have been undertaken at this point in time. Internal peer reviews were completed by Right Solutions. |
| 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. |
Validation of the model vs drillhole grades by sectional comparisons, statistical evaluation, swathe plot and population distribution analysis were favourable. The statement refers to global estimates for the entire known extent of the Area 2 deposit. No production data is available for comparison with the deposit. |
