Upgrade to Base Metals Mineral Resource at Gabanintha Project

HIGHLIGHTS

  • Upgrade to Base Metals Mineral Resource estimate for the Gabanintha Vanadium deposit reported by Australian Vanadium Limited.

  • Bryah Resources Limited holds the mineral rights to Nickel and Copper at Gabanintha.

  • Inferred Base Metals Mineral Resource of 14.3Mt containing, inter alia, 666ppm Nickel and 217ppm Copper.

Bryah Resources Limited (“Bryah” or “the Company”) is pleased to advise that Australian Vanadium Limited (ASX:AVL) (“AVL”) has reported a upgrade to the Base Metals Mineral Resource estimate for the Gabanintha Vanadium deposit located in central Western Australia ( released by AVL to ASX on 28 November 2018 and herewith attached in full ).

An Inferred Base Metals Mineral Resource of 14.3Mt containing, inter alia, 666ppm Nickel, 217ppm Copper and 0.16% Sulphur has been estimated, representing a 1.8Mt (14.4%) increase, has been reported by AVL.

Bryah holds the rights to all minerals except Vanadium/Uranium/Cobalt/Chromium/ Titanium/Lithium/Tantalum/Manganese & Iron Ore (“Excluded Minerals”). AVL retains 100% rights in the Excluded Minerals on the Gabanintha Project.

The Inferred Mineral Resource is considered by AVL to be potentially economically recoverable following metallurgical test work. AVL states that the base metal sulphide mineralisation has consistently reported to the non-magnetic fraction during the separation of the vanadium bearing magnetite. This has effectively delivered a sulphide by-product for further concentration by flotation.

AVL is presently undertaking a Preliminary Feasibility Study on development of the Gabanintha Vanadium deposit. AVL states that it intends to conduct further exploration to increase and improve the definition of the base metals mineral resource at Gabanintha.

Australian Vanadium Limited (ASX: AVL, “the Company” or “AVL”) is pleased to announce an updated Mineral Resource for its Gabanintha Vanadium Project near Meekatharra in Western Australia. The revised estimate has been conducted following a further drill campaign of 19 RC holes for 1,863m and three diamond holes for 368.2m of HQ diamond core. At the time of this Mineral Resource update, assay results for six RC holes (474m) are still pending.

Mineral resources are defined in categories of increasing geological confidence, with Measured giving the highest degree of confidence, Indicated providing the second highest level and Inferred the lowest level of confidence. In each case, continuity of mineralisation must be shown.

The updated Measured, Indicated and Inferred Mineral Resource is contained within a massive magnetite high-grade horizon and overlying lower grade disseminated magnetite horizons for a total of 183.6 million tonnes (Mt) at 0.76% V2O5. This updated figure includes a 70% increase to the Indicated Mineral Resource from the previous resource update in July (see ASX announcement, 5 July 2018, Resource Update for Gabanintha Vanadium Deposit including Cobalt, Nickel and Copper). Table 1 includes a detailed updated Mineral Resource table and Appendix 1 includes a table of the Mineral Resource broken down by the material type.

The revised Mineral Resource estimate includes a geologically distinct massive vanadium bearing magnetite high-grade zone that is the focus of current economic studies. The Measured, Indicated and Inferred Mineral Resource estimate for the massive magnetite high-grade zone (HG10 in Table 1) is 96.7Mt at 1.00% V2O5 which includes 10.2Mt at 1.11% V 2 O 5 in the Measured category, 12.1Mt at 1.05% V 2 O 5 in the Indicated category and 74.5Mt at 0.97% V 2 O 5 in the Inferred category.

The Mineral Resource of the high-grade zone has increased by 3.1Mt (3.3%). Importantly, Indicated Resources within this zone have increased by 7.2Mt (147%) . This represents an extremely high conversion from Inferred resources, supporting the high degree of geological and grade continuity at AVL’s Gabanintha project. Overall the total Mineral Resource has increased by 8.1Mt (4.6%) as a result of deeper drilling within the deposit, which remains open at depth.

There is significant potential to convert further Inferred Resources located along the Company’s 11.5km of strike length at Gabanintha (see Figure 1) to the Measured and Indicated categories, with additional targeted low-cost drilling programs. This de-risking of resources will support a longer mine life for the proposed Gabanintha vanadium operation, as outlined in the Company’s ASX Announcement on 26 September 2018 (Gabanintha presents Robust Base Case for Pre-Feasibility Study).

In addition, an Inferred Base Metals Mineral Resource of 14.3Mt containing 208ppm Cobalt, 666ppm Nickel, 217ppm Copper[1] and 0.16% Sulphur has been estimated, representing a 1.8Mt increase. The Inferred Mineral Resource is contained exclusively within the fresh massive high-grade zone (HG10) in Fault Block 20 of the resource model, (see Figure 1 – Location and Fault Blocks and 5 – Panel images) and is considered to be potentially economically recoverable following metallurgical test work conducted by the Company. The base metal sulphide mineralisation has consistently reported to the non-magnetic fraction during the separation of the vanadium bearing magnetite. This has effectively concentrated sulphide minerals enabling further concentration by flotation methods, (see ASX announcement, 22 May 2018, Cobalt added to Vanadium at Gabanintha and this announcement).

The revised Mineral Resource estimate, including the estimation of sulphide base metals content, provides an improved basis for the PFS currently being undertaken by the Company.

De-risking the Gabanintha project

AVL’s Managing Director Vincent Algar said, “ The modifications to the vanadium resource increased the size, added confidence and further reduced risk to the Gabanintha project.

“The value of the recent drilling of just 19 drillholes along strike and the consequent low-cost addition of Indicated category vanadium resources, key base metal values and important geo-metallurgical parameters to the resource model, added significantly to the quality of the mine plan that will emerge from the PFS. The increased understanding and confidence further strengthens Gabanintha’s position as a world-class vanadium project in its size, grade and metallurgical recovery parameters.

“This important revision to the Gabanintha resource further de-risks the foundations on which we can build an outstanding Australian project.

“This update highlights our ability to leverage our significant strike length advantage to cheaply add more low-risk resource, optionality and mine life to the project. Shallower resources are worth more to us than deeper, expensive high stripping ratio resources. We have confirmed that the deposit extends at depth, but the long-term value lies in further quality along strike.

“We continue to develop our technical understanding of the deposit and its geo-metallurgical responses and will carry on this work into the definitive studies next year.

“By incorporating these new results into our PFS, we are better able to attract the attention of key vanadium investors and market participants. We are looking to meet the needs of the steel industry and the rapidly developing Vanadium Redox Flow Battery industry.

Further technical details of this updated Mineral Resource estimate for Gabanintha are contained below in this release. The information that refers to Mineral Resources in this statement was prepared and last revised under the JORC Code 2012 on 5th July 2018, by independent consultants Trepanier Pty Ltd and is compared in this ASX announcement in Table 2. Additional data and lithological interpretations have now been incorporated and modelled into a revised and updated resource estimate.

Activities focused on advancing Gabanintha towards feasibility

The release of the updated Mineral Resource statement supports the activities of the Company to advance the Gabanintha vanadium project. Key activities currently underway include:

  • A Pre-Feasibility Study under the management of Wood Mining and Metals, external consultants and members of the AVL technical team.

  • Metallurgical test work including sodium salt roast leach test work and process circuit design.

  • Work is ongoing on the geo-metallurgical understanding of the mineralised domains to support processing circuit design, performance prediction and mine scheduling.

  • Metallurgical test work has identified the opportunity to produce a base-metal rich sulphide (Co, Ni, Cu) concentrate by flotation from the non-magnetic tailings stream. Further work will be conducted to refine the resource opportunity, concentrate quality and economic benefit.

  • A detailed mining study including pit optimisation and a preliminary assessment of an initial mine schedule is well advanced.

  • Preparation of the final PFS document is currently underway.

  • Determination of environmental constraints to the project and progress towards completion of a Native Title Mining Agreement and approval of a Mining Lease.

  • Preparation of vanadium pentoxide (V 2 O 5 ) powder for battery and Vanadium Carbo-Nitride (VCN) customer evaluation are underway.

The Company will also incorporate results from additional research it will be conducting on vanadium electrolyte for use in vanadium redox flow batteries (VRFB). The manufacture of electrolyte is a process that can be achieved as part of the processing of vanadium ore. It offers the Company an opportunity to value-add to the project and develop a greater presence in the VRFB market.

PFS Progress Update

The final PFS is nearing completion and reports will be handed to the AVL Board in December 2018. The Company released a PFS base case to the ASX on 26 September 2018. The PFS base case work outlined an initial production scenario at Gabanintha.

The level of study in the final PFS report will be to ± 25% on capital and operating costs and will include a maiden Ore Reserve for the Project. The Company’s aim is to deliver a realistic and achievable study, able to support future investment decisions.

Key focuses for the Company include minimising environmental impacts, identifying and mitigating process and project risks at an early stage, developing a clear pathway to a timely design and the building of a world class, long-life vanadium operation.

November 2018 Mineral Resource Estimation (JORC 2012)

The updated Mineral Resource estimate incorporates results from a campaign of RC and diamond drilling during September 2018. 19 RC holes for 1,863m were drilled and three HQ diamond tails on RC pre-collars for 368.2m of HQ core. One diamond tail was drilled in the southern portion of fault block 20 to extend the drill dataset in fresh high grade V2O5 material with base metals credits. Ten RC holes were drilled to infill between existing drill sections to increase the Resource Category confidence in Fault Block 17 from Inferred to Indicated. A further six RC holes were drilled as infill lines in fault block 6. The location of the fault blocks is shown in Figure 1. Figure 2 shows the drill hole collar locations for both existing drilling and the 2018 drill campaign. The drill program was designed to collect geotechnical data as input for open pit design for the ongoing PFS. Two of the diamond tails were drilled into the hanging wall rocks, towards the southwest, to test for any significant structures where the western pit wall is designed. These geotechnical holes do not contribute data to the updated Mineral Resource. The RC drill results for fault block 6 are pending receipt, loading to the company database and interpretation at the time of this update, so are not included.

The updated Mineral Resource estimate completed and reported in compliance with the JORC Code 2012 standard for the project incorporated 79.25% of the existing drilling data (see Table 3) including data from the Company’s 2009 and 2015 RC and diamond drilling programs. This included 223 RC and 18 Diamond Core holes for 20,974 metres over an 11 kilometre strike length at AVL’s Gabanintha vanadium, titanium and iron deposit. Of these, 17,530m were used in the grade estimate.

The estimation was carried out by Trepanier Pty Ltd, resulting in the estimation of Measured, Indicated, and Inferred Mineral Resources. All mineralised domains were constructed using geological information and considering a nominal cutoff for inclusion of above 0.4% V2O5 for the low-grade ore zones and above 0.7% V2O5 within the high-grade zone in the Mineral Resource estimate (see Table 1) for a total resource of:

Comparison with May 2018 Mineral Resource Estimation

The updated Mineral Resource has had a minor impact on the overall tonnage and Measured category, but has resulted in a conversion of just over 7 million tonnes of Inferred material to Indicated Resource category. Domains for oxide (completely weathered), transitional (partially weathered) and fresh rock (no weathering) were updated based on the SATMAGAN[2] dataset collected throughout 2018 (979 samples in the massive high-grade zone). Through this review some material at the north end of fault block 20 was re-assigned from transitional to oxide material, and the weathering profile was shallowed in the central and southern part of fault block 20, resulting in a net increase in transitional material and a decrease in oxide material. The degree of weathering determines the extent to which the high-grade vanadium domain can be beneficiated through magnetic separation prior to roasting. Work conducted by the Company has demonstrated vanadium recovery from oxide materials. The Company has previously demonstrated successful magnetic separation of vanadium for transitional and fresh rock. The distinction and successful identification of the oxidation state of the ore is considered an important aspect in the resource definition and subsequent processing.

The principal differences between the May 2018 mineral resource estimation and the current November 2018 estimation are listed below:

  • Drill data is incorporated from an additional one HQ diamond core hole (18GEDH003) in fault block 20 and 10 RC drillholes in fault block 17 that is immediately south of fault block 20.

  • The diamond hole tests the massive magnetite high-grade vanadium zone and base metals at a depth of about 145m below surface, with an intercept of 18.6m @ 1.10% V2O5, 220ppm Co, 757ppm Ni and 173ppm Cu from 168.5m returned, including 11m @ 1.23% V2O5 from 173m. (Details see Appendix 2)

  • Further update of the oxide, transition and top of fresh surfaces using magnetic susceptibility, LOI and SATMAGAN data, following calibration of the SATMAGAN dataset for magnetic material recovery using benchscale magnetic test data.

  • Re-estimation of cobalt, nickel, copper and sulphur values within the measured and indicated part of the deposit.

RC Drilling

In total 11 RC drillholes were completed as infill lines in fault block 17, that is immediately south of the best drilled area in fault block 20. The massive magnetite high-grade vanadium zone was intercepted in all of the new holes drilled into block 17 at grades consistent with or better than the existing drilling in the area. The location of all drill collars is shown in Figure 2. On the 30 October (see ASX announcement, Gabanintha Drilling Confirms High-Grade Vanadium Zone Continuity) results for most of the RC drilling were released. Results for two further drillholes have since been received and incorporated into the model, which are 18GERC005A and 18GERC005B. These two drillholes on the northern section in fault block 17 confirmed the expected full thickness of the high-grade zone after issues were noted with sample quality in hole 18GERC005 that returned a smaller than expected intercept.

A full list of available results from the 2018 drilling and other historic drillholes in fault block 17 are included in this report in Appendix 2.

Oxidation zone re-interpretation and bulk density assignment

To support geo-metallurgical modelling for future mining and processing study work, the interpretation of the oxidation profile was refined through the three zones – oxide, transition and fresh. The reinterpretation was facilitated using geological logging, element assays, core photos, magnetic susceptibility logs plus LOI and SATMAGAN data. The SATMAGAN dataset was collected throughout 2018 culminating in 979 readings through the high-grade zone (model zone HG10). The need to achieve a better understanding of the oxidation boundaries is driven by the following factors:

  • Metallurgical testwork indicates that the degree of oxidation directly affects the recovery of iron and vanadium.

----- Start of picture text -----

----- End of picture text -----

==> picture [595 x 83] intentionally omitted <==

  • Higher levels of oxidation result in increased silica and alumina being retained in the resulting magnetic concentrate.

  • Process design criteria and plant optimisation, and

  • Mine scheduling to satisfy plant production capacity.

Based on the reinterpreted oxidation coding and the collection of a further 13 bulk density measurements in 18GEDH003, the assignment of the bulk densities for the different zones was also reviewed. The outcome of this review is that there is no material change required to the regressions used for the bulk density in the May 2018 Mineral Resource update. Clear correlations of bulk density versus Fe2O3 were chosen as the most appropriate estimation methods of bulk density for the different parts of the oxidation profile. Details of the revised density assignment based on 313 bulk density measurements are outlined in Appendix 3, JORC Table 1, Section 3. Table 1 in Appendix 1 shows the total Mineral Resource by oxidation domain. Table 2 in Appendix 1 shows the high-grade massive magnetite zone reported by oxidation domain.

Note: The 2018 Mineral Resource Estimation excluded some older (pre-2007) RC holes (GRC001 to GRC017) due to uncertainty about assay quality assurance. This had minor impact on the wireframe estimations for volume and grade as more recent, better quality holes were drilled nearby. YRR refers to previous company name for AVL. The 2018 Mineral Resource Estimation does not include some results from the RC drill campaign as assays were outstanding at the time of estimation.

Mineral Resource Estimation - Base Metals and Sulphur

On the 22[nd] May 2018 (see ASX announcement, Cobalt added to Vanadium at Gabanintha), AVL announced the successful recovery of cobalt, nickel and copper in a sulphide concentrate, adding another saleable battery metal opportunity. To evaluate the available sulphide hosted base metal content (cobalt, nickel and copper), the updated resource model includes the estimation of these elements and sulphur in the fresh material.

An Inferred base metal Mineral Resource has been defined at Gabanintha containing 14.3Mt containing 208ppm Cobalt, 666ppm Nickel, 217ppm Copper and 0.16% Sulphur. The Inferred Mineral Resource is contained exclusively in the fresh massive high-grade magnetite zone (model zone HG10) in Fault Block 20 of the resource model. (See Figure 5 – Panel images). Due to a lower number of informing samples for the fresh zone, the classification of sulphide hosted base metal material in the resource is Inferred. The Inferred base metal resource is constrained to the high-grade massive magnetite zone in Fault Block 20, which is the area of the highest drilling density of holes that penetrate into fresh material. Table 4 below shows the sulphide hosted base metal material classified as Inferred Resources. The location of the Inferred base metal resource is indicated in Figures 3 and 5.

The base metal sulphide mineral resource is potentially economically recoverable following metallurgical test work conducted by the Company. The base metal sulphide mineralisation has been found to consistently report to the non-magnetic fraction during the separation of the vanadium bearing magnetite, enabling further sulphide concentration by flotation.

Table 4 Gabanintha Project – Mineral Resource for sulphidic base metals (cobalt, nickel and copper) constrained to Domain 10 (high-grade vanadium domain) for Fault Block 20 fresh material

Zone Classification Mt Co ppm Ni ppm Cu ppm S %

Fresh material Inferred 14.3 208 666 217 0.16
Total 14.3 208 666 217 0.16

The continuity along strike and down dip of the sulphide hosted base metals is strongly supported by the geological model and the vanadium resource estimation model but does not yet have the sample support in the fresh material of other fault blocks to allow further classification of mineral resources. The Company intends to conduct further exploration to increase and improve the definition of the base metal resource at Gabanintha.

Summary of Resource Estimate and Reporting Criteria

As per ASX Listing Rule 5.8 and the 2012 JORC reporting guidelines, a summary of material information used to estimate the Mineral Resource is detailed below, (for more detail please refer to Table 1, Sections 1 to 3 included in Appendix 2).

Geology and geological interpretation

The Gabanintha deposit, located 40km south of the town of Meekatharra in Western Australia, is a layered intrusive body smaller than, but displaying similar characteristics to, the Igneous Bushveld Complex in South Africa. Some of the world’s most significant platinum, vanadium and chromite deposits are hosted by the Bushveld Complex.

The deposit is also similar to the Windimurra vanadium deposit and the Barrambie vanadium-titanium deposit located 260km south and 150km southeast of Gabanintha respectively. The mineral deposit

consists of a basal massive magnetite zone (10m - 15m in drilled thickness), overlain by up to five magnetite banded gabbro units between 5m and 30m thick, separated by thin, very low grade mineralisation (<0.3% V2O5) waste zones. The sequence is overlain in places by a lateritic domain, a transported domain (occasionally mineralised) and a thin barren surface cover domain.

Eight mineralised domains were defined during the logging, interpretation and statistical modelling process which were composed of:

  • One massive magnetite high-grade domain (split on oxide, transition and fresh boundary).

  • Four disseminated magnetite low-grade domains (split on oxide, transition and fresh boundary).

  • One laterite domain, and

  • Two transported domains.

The north-northwest striking deposit is affected by a number of regional scale faults which offset the entire deposit (See Figure 1 – location diagram), breaking the deposit into a series of kilometre scale blocks. The larger blocks show relatively little signs of internal deformation, with strong consistency in the layering being visible in drilling and over long distances between drillholes (see sections in Figures 3-4). The total magnetic intensity geophysical image shows clearly the trace of the high-grade massive magnetite zone, as well as the location of the faults. This image was used to guide the modelling of the mineralized domain layers and define the faults blocks which form the boundaries of the extrapolated domains.

Gabanintha differs from both the Barrambie and Windimurra deposits by the consistent presence along strike of the 10-15m thick basal massive magnetite zone and the higher overall vanadium grade of the Gabanintha deposit[1] . (Gabanintha 0.76% V2O5 overall[3] , Windimurra 0.48% V2O5 and Barrambie 0.63% V2O5[4] ). The grades observed in drilling allow extremely favourable comparison with other vanadium deposits globally.

The high-grade domain modelling focused on the discrete high-grade layer at the base of the westerly dipping mineralised package as well as defining several continuous low-grade mineralisation units above the main zone. The mineralised zones were modelled using a combination of geological, geochemical and grade parameters, focused on continuity of zones between drillholes on section and between sections.

The average strike of the high-grade domain is approximately 140-150º and generally dip 45º to 65º to the south-west, with the smaller and shallower (transported and lateritic) domains dipping 5º to 10º also to the south-west. Cross sections through the resource model showing drilling and grade interpolation are shown in Figures 3-5.

The high and low-grade domains are split by the base of complete oxidation and the base of partial oxidation, to define oxide, transition and fresh zones.

3 Details of the current Mineral Resource estimate for Gabanintha are contained in this release. The information that refers to Mineral Resources in this announcement was prepared and first disclosed under the JORC Code 2004. Additional drilling in 2015 was incorporated and modelled into a revised and updated resource estimate to comply with the JORC Code 2012. The Gabanintha Mineral Resource was last revised in September 2017.

Drilling techniques and hole spacing

Diamond drillholes account for 12% of the drill metres comprising HQ and PQ3 sized core. RC drilling (generally 135mm to 140mm face-sampling hammer) accounts for the remaining 88% of the drilled metres. Four of the diamond holes have RC pre-collars (GDH911, GDH913, GDH916, 18GEDH003), otherwise all holes are drilled from surface. The higher density drilled areas of the deposit (fault blocks 22 and 20) have approximately 80m to 100m spacing by northing and 25m to 30m spacing by easting. The fault block south of the main zone (17) has drill line spacings that average 140 m spacing and maintains the 25m to 30m spacing by easting. South of fault block 17 (northing about 7014600 mN), the drillhole spacing increases to several hundred metres in the northing direction but maintains roughly the same easting separation as the better drilled area.

Sampling and sub-sampling techniques

Diamond core was quarter-core sampled at regular intervals (usually one metre) and constrained to geological boundaries where appropriate. Most of the RC drilling was sampled at one metre intervals, apart from the very earliest programme in 1998. Diamond core was drilled predominantly at HQ size for the earlier drilling (2009), with the 2015 drilling at PQ3 size.

RC drilling samples were collected at one metre intervals and passed through a cone splitter to obtain a nominal 2-5kg sample at an approximate 10% split ratio. These split samples were collected in prenumbered calico sample bags. The sample was dried, crushed and pulverised to produce a sub sample (~200g) for laboratory analysis using XRF and total LOI by thermo-gravimetric analysis.

Field duplicates, standards and blanks have been inserted into the sampling stream at a rate of nominally 1:20 for blanks, 1:20 for standards (including internal laboratory), 1:40 for field duplicates, 1:20 for laboratory checks and 1:74 for umpire assays.

Sample analysis method

All samples for Gabanintha were assayed for the full iron ore suite by XRF (24 elements) and for total LOI by thermo-gravimetric technique. The method used is designed to measure the total amount of each element in the sample.

Although the commercial laboratories changed over time for different drilling programmes, they have been industry recognized and certified and their laboratory procedures all appear to be in line with industry standards and appropriate for iron ore deposits.

Samples are dried at 105[°] C in gas fired ovens for 18-24 hours before RC samples being split 50:50. One portion is retained for future testing, while the other is then crushed and pulverised. Sub-samples are collected to produce a 66g sample that is used to produce a fused bead for XRF based analysing and reporting.

Further SATMAGAN analysis was conducted on 979 archive pulp samples from 2015 RC drilling, at Bureau Veritas laboratory during 2018, to further characterize the weathering profile. SATMAGAN measurements are used to determine the amount of iron present as magnetic species, such as magnetite, maghemite and kenomagnetite. The amount of iron present as magnetite or other magnetic species is directly proportional to the degree of rock freshness.

Drilling, sampling, preparation and analysis techniques are detailed in Appendix 3, Table 1 .

Cut-off grades

The high-grade domain wireframe is defined by a nominal 1.0% V2O5 grade cut-off, with occasional intervals between 0.7% and 1.0% selected to ensure domain continuity. The wireframes for the lowgrade domains are based on a nominal 0.4% V2O5 grade cut-off (with occasional material above 0.3% V2O5 included to ensure domain continuity) and comprised of eight sub-domains. A similar approach is used as in the high-grade domain regarding selection of samples for sub-domain continuity, with samples below 0.4% V2O5 being occasionally selected within the domain. Everything encapsulated within the defined wireframes is reported in the resource tables.

Estimation methodology

Trepanier completed Ordinary Kriged estimates for V2O5, TiO2, Fe2O3, SiO2, Al2O3, Cr2O3, Co, Cu, Ni, S and loss on ignition (LOI) using Surpac™ software. Potential top-cuts were checked by completing an outlier analysis, but in this instance, no top-cutting was required. Variograms were completed for the estimated variables in the high-grade domain and the combined low-grade sub-domains. Grade estimates are keyed on the combined fault block and domain codes for the high-grade domain and the combined low-grade sub-domains. Domains 6, 7 and 8 were interpreted to be shallow, flat lying alluvial material and are estimated separately. Grade is estimated into parent cells with dimensions of 40 mN, 10 mE and 5 mRL with sub-celling allowed to ensure accurate volume representation of the wireframed mineralisation interpretation. All sub-cells are assigned the same grade as its parent.

The current estimate uses only bulk density measurements which include 231 bulk density samples from the diamond core as determined by the Archimedes method. A total 313 bulk density measurements were used to calculate average densities. Samples were subdivided according to their position in relation to the ore zones and the oxidation surface. Correlation charts were created for each element, with a very strong positive correlation defined for bulk density and Fe2O3 content. From this analysis a regression was assigned based on the Fe2O3 grade of each block dependent on oxide code.

Classification criteria

The estimate is classified according to the guidelines of the 2012 JORC Code as Measured, Indicated and Inferred Mineral Resource. The classification has taken into account the relative confidence in tonnage and grade estimations, the reliability of the input data, the Competent Person’s confidence in the continuity of geology and grade values and the quality, quantity and distribution of the drillhole and supporting input data.

In applying the classification, Measured Mineral Resource has generally been restricted to the oxide, transition and fresh portion of the high-grade domain where the drillhole line spacing is less than 80 mN to 100 mN. Indicated Mineral Resource is generally restricted to the oxide, transition and fresh high-grade and low-grade in the same area of relatively closely-spaced drilling. The remainder of the modelled zones to the north and south of the Measured and Indicated Resource with supporting drilling, mapping and geophysical data have been classified as Inferred Mineral Resource. The classification applied relates to the global estimate of V2O5 and at the reported cut-off grades only. At different V2O5 grade cut-offs, the applied classification scheme may not be valid. Details of the cut-off grades and resource estimation parameters are shown in Appendix 3 at the end of this report.

Mining and metallurgical methods and parameters

Optimisation studies have commenced as part of the pre-feasibility study that is currently under way. They indicate open pit mining would be an appropriate mode of extraction through the fault blocks that have Indicated and Measured resources defined.

Metallurgical testwork has identified four main types of mineralised high-grade material for processing, defined as oxide, transition, fresh and fresh with high sulphur. Metallurgical testwork (see ASX announcements 20 February 2018 and 24 April 2018), has demonstrated that the basal high-grade massive mineralisation can be concentrated through levels of magnetic separation processes (oxide, transition and fresh) achieving varying degrees of recovery of vanadium and removing silica and alumina from the feed. The concentrates achieved are considered suitable for processing via industry standard roast-leach processes to be confirmed by subsequent test work.

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
specialized industry standard measurement
tools appropriate to the minerals under
investigation, such as down hole gamma
sondes, or handheld XRF instruments, etc).
These examples should not be taken as
limiting the broad meaning of sampling.
The Gabanintha deposit was sampled using diamond core and reverse circulation (RC) percussion drilling from
surface.
At the time of the latest Mineral Resource estimation, a total of 223 RC holes and 18 diamond holes (4 of which
are diamond tails) were drilled into the deposit. 59 of the 251 holes were either too far north or east of the main
mineralisation trend, or excised due to being on another tenancy. One section in the southern part of the deposit
(holes GRC0156, GRC0074, GRC0037 and GRC0038) was blocked out and excluded from the resource due to
what appeared to be an intrusion which affected the mineralised zones in this area. Of the remaining 182
drillholes, one had geological logging but no assays. The total metres of drilling available for use in the
interpretation and grade estimation was 16,287m at the date of the most recent resource estimate.
The initial 17 RC drillholes were drilled by Intermin Resources NL (IRC) in 1998. These holes were not used in the
2015 and 2017 estimates due to very long unequal sample lengths and a different grade profile from subsequent
drilling. 31 RC drillholes were drilled by Greater Pacific NL in 2000 and the remaining holes for the project were
drilled by AVL Australian Vanadium Ltd (Previously YRR) between 2007 and 2015. This drilling includes 17diamond
holes (3 of which are diamond tails) and 57 RC holes, for a total of 17,144m drilled.
All of the drilling sampled both high and low-grade material and were sampled for assaying of a typical iron ore suite,
including vanadium and titanium plus base metals and sulphur.
Include reference to measures taken to
ensure sample representivity and the
appropriate calibration of any measurement
tools or systems used.
In 2015, the drillhole collars were originally set out using hand held GPS and on completion the collars were
surveyed by survey contractors using high precision digital GPS. The earlier drilling programmes were
retrospectively surveyed using DGPS at the remaining collar PVC pipe positions. Only a few of the very earliest
drilled holes (1998) were not able to have their collars accurately surveyed, as they had been rehabilitated and their
position was not completely clear. Downhole surveys were completed for all of the diamond holes, using gyro
surveying equipment, as well as the RC holes drilled in 2015 (from GRC0159). All of the other RC holes were given
a nominal -60odip measurement. These older RC holes were almost all 120m or less in depth.
Diamond core was quarter-core sampled at regular intervals (usually one metre) and constrained to geological
boundaries where appropriate. Most of the RC drilling was sampled at one metre intervals, apart from the very
earliest programme in 1998.
The 2018 diamond core was half-core sampled at regular intervals (usually one metre) and constrained to
geological boundaries where appropriate. The RC drilling was sampled at one metre intervals using a cone splitter
on the rig to obtain a 2.5 – 3.5 kg sample of each metre. Field duplicates were collected for every 50th drill metre to
checksamplerepresentativityfromthe drill rig splitter.

Aspects of the determination of
mineralisation that are Material to the Public
Report.
RC drilling samples were collected at one metre intervals and passed through a cone splitter to obtain a nominal 2-
5kg sample at an approximate 10% split ratio. These split samples were collected in pre-numbered calico sample
bags. The sample was dried, crushed and pulverised to produce a sub sample (~200g) for laboratory analysis using
XRF and total LOI by thermo-gravimetric analysis.
Diamond core was drilled predominantly at HQ size for the earlier drilling (2009) and entirely HQ for the 2018
program, with the 2015 drilling at PQ3 size.
Field duplicates, standards and blanks have been inserted into the sampling stream at a rate of nominally 1:25 for
blanks, 1:11 for standards (including internal laboratory), 1:10 for field duplicates, 1:9 for lab checks and 1:74 for
umpire assays.
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.).
Diamond drillholes account for 12% of the drill metres and comprises HQ and PQ3 sized core. RC drilling (generally
135 mm to 140 mm face-sampling hammer) accounts for the remaining 88% of the drilled metres. Six of the
diamond holes have RC pre-collars (GDH911, GDH913 & GDH916, 18GEDH001, 002 and 003), otherwise all holes
are drilled from surface.
No core orientation data has been recorded in the database.
11 RC holes were drilled during the 2018 program and three HQ diamond tails were drilled on RC pre-collars for
resource and geotechnical purposes. The core was not orientated but all diamond holes were logged by OTV and
ATV televiewer.
Drill sample
recovery
Method of recording and assessing core and
chip sample recoveries and results
assessed.
Diamond core recovery is measured when the core is recovered from the drill string. The length of core in the tray is
compared with the expected drilled length and is recorded in the database.
For the 2018 and 2015 drilling, RC chip sample recovery was gauged by how much of the sample was returned from
the cone splitter. This was recorded as good, fair, poor or no sample. The older drilling programmes used a different
splitter, but still compared and recorded how much sample was returned for the drilled intervals. All of the RC
sample bags (non-split portion) from the 2018 programme were weighed as an additional check on recovery.
An experienced AVL geologist was present during drilling and any issues noticed were immediately rectified.
No significant sample recovery issues were encountered in the RC drilling.
Measures taken to maximize sample
recovery and ensure representative nature
of the samples.
Core depths are checked against the depth given on the core blocks and rod counts are routinely carried out by the
drillers. Recovered core was measured and compared against driller’s blocks.
RC chip samples were actively monitored by the geologist whilst drilling.
All drillholes are collared with PVC pipe for the first metre or two, to ensure the hole stays open and clean from
debris.
Whether a relationship exists between
sample recovery and grade and whether
sample bias may have occurred due to
preferential loss/gain of fine/coarse material.
No relationship between sample recovery and grade has been demonstrated.
Two shallow diamond drillholes drilled to twin RC have been completed to assess sample bias due to preferential
loss/gain of fine/coarse material.
Geologica Pty Ltd is satisfied that the RC holes have taken a sufficiently representative sample of the mineralisation
and minimal loss of fines has occurred in the RC drilling resulting in minimal sample bias.

Criteria JORC Code Explanation Commentary
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.
All diamond core and RC chips were geologically logged.
Diamond core was geologically logged using predefined lithological, mineralogical and physical characteristics (such
as colour, weathering, fabric, texture) logging codes and the logged intervals were based on lithological intervals.
RQD and recoveries were also recorded. Minimal structural measurements were recorded (bedding to core angle
measurements) but have not yet been saved to the database.
The logging was completed on site by the responsible geologist.
All of the drilling was logged onto paper and was transferred to a SQL Server drillhole database using DataShedTM
database management software. The database is managed by Mitchell River Group (MRG). The data was checked
for accuracy when transferred to ensure that correct information was recorded. Any discrepancies were referred
back to field personnel for checking and editing.
All core trays were photographed wet and dry.
RC chips were logged generally on metre intervals, with the abundance/proportions of specific minerals, material
types, lithologies, weathering and colour recorded.
Physical hardness for RC holes is estimated by chip recovery and properties (friability, angularity) and in diamond
holes by scratch testing.
From 2015, drilling also had magnetic susceptibility recorded, with the first nine diamond holes (GDH901-GDH909)
having readings taken on the core every 30 cm or so downhole. Holes GDH910 to GDH917 had readings every 50
cm and RC holes GRC0159 to GRC0221 had readings for every one metre green sample bag.
All of the diamond core and RC samples have been logged to a level of detail to support Mineral Resource

The 2018 and 2009 HQ diamond core was cut in half and the half core samples were sent to the laboratories for
assaying. Sample intervals were marked on the core by the responsible geologist considering lithological and
structural features.
No core was selected for duplicate analysis.
The 2015 PQ Diamond core was cut in half and then the right hand side of the core (facing downhole) was halved
again using a powered core saw. Quarter core samples were sent to the laboratories for assaying. Sample intervals
were marked on the core by the responsible geologist considering lithological and structural features.

RC drilling was sampled by use of an automatic cone splitter for the 2018 and 2015 drilling programmes; drilling was
generally dry with a few damp samples. Older drilling programmes employed riffle splitters to produce the required
sample splits for assaying. One in 40 to 50 RC samples was resampled as field duplicates for QAQC assaying.

Criteria JORC Code Explanation Commentary
For all sample types, the nature, quality and
appropriateness of the sample preparation
technique.
The sample preparation techniques employed for the diamond core samples follow standard industry best practice.
All samples were crushed by jaw and Boyd crushers and split if required to produce a standardised ~3kg sample for
pulverising. The 2015 programme RC chips were split to produce the same sized sample.
All samples were pulverised to a nominal 90% passing 75 micron sizing and sub sampled for assaying and LOI
determination tests. The remaining pulps are stored at an AVL facility.
The sample preparation techniques are of industry standard and are appropriate for the sample types and proposed
assaying methods.
Quality control procedures adopted for all
sub-sampling stages to maximize
representivity of samples.
Field duplicates, standards and blanks have been inserted into the sampling stream at a rate of nominally 1:25 for
blanks, 1:11 for standards (including internal laboratory), 1:10 for field duplicates, 1:9 for lab checks and 1:74 for
umpire assays. Also for the recent sampling at BV, 1 in 20 samples were tested to check for pulp grind size.
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.
To ensure the samples collected are representative of the in-situ material, a 140mm diameter RC hammer was used
to collect one metre samples and either HQ or PQ3 sized core was taken from the diamond holes. Given that the
mineralisation at Gabanintha is either massive or disseminated magnetite/martite hosted vanadium, which shows
good consistency in interpretation between sections and occurs as percentage values in the samples, Geologica Pty
Ltd considers the sample sizes to be representative.
Core is not split for duplicates, but RC samples are split at the collection stage to get representative (2-3kg)
duplicate samples.
The entire core sample and all the RC chips are crushed and /or mixed before splitting to smaller sub-samples for
assaying.
Whether sample sizes are appropriate to the
grain size of the material being sampled.
As all of the variables being tested occur as moderate to high percentage values and generally have very low
variances (apart from Cr2O3), the chosen sample sizes are deemed appropriate.
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.
All samples for Gabanintha were assayed for the full iron ore suite by XRF (24 elements) and for total LOI by
thermo-gravimetric technique. The method used is designed to measure the total amount of each element in the
sample. Some 2015 RC samples in the oxide profile were also selected for SATMAGAN analysis that is a measure
of the amount of total iron that is present as magnetite (or other magnetic iron spinel phases, such as maghemite or
kenomagnetite). SATMAGAN analysis was conducted at Bureau Veritas (BV) Laboratory in early 2018. Analysis
results of the relevant portions of the RC holes by Satmagan are pending, but underway.
Although the laboratories changed over time for different drilling programmes, the laboratory procedures all appear
to be in line with industry standards and appropriate for iron ore deposits, and the commercial laboratories have
been industry recognized and certified
Samples are dried at 105oC in gas fired ovens for 18-24 hours before RC samples being split 50:50. One portion is
retained for future testing, while the other is then crushed and pulverised. Sub-samples are collected to produce a
66g sample that is used to produce a fused bead for XRF based analysing and reporting.
Certified and non-certified Reference Material standards, field duplicates and umpire laboratory analysis are used
for quality control. The standards inserted by AVL during the 2015 drill campaign were designed to test the V2O5
grades around 1.94%, 0.95% and 0.47%. The internal laboratory standards used have varied grade ranges, but do
coverthese three grades aswell. During2018, three CertifiedReferenceMaterials (CRMs)were used byAVLas

field standards. These covered the V2O5grade ranges around 0.327%, 0.790% and 1.233%. These CRMs are also
certified for other relevant major element and oxide values, including Fe, TiO2, Al2O3, SiO2, Co, Ni and Cu (amongst
others).
Most of the laboratory standards used show an apparent underestimation of V2O5, with the results plotting below the
expected value lines; however the results generally fall within ± 5-10% ranges of the expected values. The other
elements show no obvious material bias.
Standards used by AVL generally showed good precision, falling within 3-5% of the mean value in any batch. The
standards were not certified, but compared with the internal laboratory standards (certified) they appear to show
good accuracy as well.
Field duplicate results from the 2015 drilling all fall within 10% of their original values.
The BV laboratory XRF machine calibrations are checked once per shift using calibration beads made using exact
weights and they performed repeat analyses of sample pulps at a rate of 1:20 (5% of all samples). The lab repeats
comparevery closelywiththe originalanalysisforallelements.
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.
The only geophysical readings taken for the Gabanintha core and RC samples and recorded in the database were
magnetic susceptibility. This was undertaken using an RT1 hand magnetic susceptibility meter (CorMaGeo/Fugro)
with a sensitivity of 1 X 10–5 (dimensionless units). The first nine diamond holes (GDH901 – GDH909) were
sampled at approximately 0.3m intervals, the last eight (GDH910 – GDH917) at 0.5m intervals and the RC chip
bags for every green bagged sample (one metre).
Four completed diamond drillholes were down hole surveyed by acoustic televiewer (GDH911, 912, 914 and 915)
as a prequel to geotechnical logging during the 2015 drill campaign. A further six holes from the 2018 campaign
have been down hole surveyed using acoustic televiewer and optical televiewer (18GEDH001, 002 and 003 and
partial surveys of 18GERC005, 008 and 011) for 627 metres of data.
Televiewer data was also collected during 2018 on some of the holes drilled in 2015 and prior. The holes surveyed
were GRC0019, 0024, 0168, 0169, 0173, 0178, 0180, 0183, 0200 and Na253, Na258 and Na376 for a further
286.75 m of data.
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.
QAQC results from both the primary and secondary assay laboratories show no material issues with the main
variables of interest for the recent assaying programmes.
Verification of
sampling and
assaying
The verification of significant intersections by
either independent or alternative company
personnel.
Diamond drill core photographs have been reviewed for the recorded sample intervals. Geologica Pty Ltd
Consultant, Brian Davis, visited the Gabanintha project site and the BV core shed and assay laboratories in
September 2015 and on multiple occasions over a 10 year period. Whilst on site, the drillhole collars and remaining
RC chip samples were inspected. All of the core was inspected in the BV facilities in Perth and selected sections of
drillholes were examined in detail in conjunction with the geological logging and assaying.

laboratories as electronic data which were imported directly into the SQL Server database. Survey and collar
location data were received as electronic data and imported directly to the SQL database.
All of the primary data have been collated and imported into a Microsoft SQL Server relational database, keyed on
borehole identifiers and assay sample numbers. The database is managed using DataShed TM database
management software. The data was verified as it was entered and checked by the database administrator (MRG)
and AVLpersonnel
Discuss any adjustment to assay data. No adjustments or calibrations were made to any assay data, apart from resetting below detection limit values to

Location of
data points
Accuracy and quality of surveys used to
locate drillholes (collar and down-hole
surveys), trenches, mine workings and other
locations used in Mineral Resource
estimation.
For the 2018 drilling, all collars were set out using a handheld GPS. After drilling they were surveyed using a
Trimble real-time Kinematic (RTK) GPS system. The base station accuracy on site was improved during the 2015
survey campaign and a global accuracy improvement was applied to all drillholes in the Company database.
For the 2015 drilling, all of the collars were set out using a Trimble RTK GPS system. After completion of drilling all
of the collars were re- surveyed using the same tool.
Historical drill holes were surveyed with RTK GPS and DGPS from 2008 to 2015, using the remaining visible collar
location positions where necessary. Only five of the early drillholes, drilled prior to 2000, had no obvious collar
position when surveyed and a best estimate of their position was used based on planned position data.
Specification of the grid system used. The grid projection used for Gabanintha is MGA_GDA94, Zone 50. All reported coordinates are referenced to this
grid.

Quality and adequacy of topographic control. High resolution Digital Elevation Data was captured by the Company in June 2018 over the MLA51/878 tenement
area using fixed wing aircraft, with survey captured at 12 cm GSD using an UltraCam camera system operated by
Aerometrex. The data has been used to create a high-resolution Digital Elevation Model on a grid spacing of 5m x
5m, which is within 20 cm of all surveyed drill collar heights, once the database collar positions were corrected for
the improved ground control survey, that was also used in this topography survey. The vertical accuracy that could
be achieved with the 12 cm GSD is +/- 0.10 m and the horizontal accuracy is +/- 0.24m. 0.5m contour data has also
been generated over the mining lease application. High quality orthophotography was also acquired during the
survey at 12cm per pixel for the full lease area, and visual examination of the imagery shows excellent alignment
with the drill collar positions. The November 2018 Mineral Resource used this surface for topographic control within
the Mining Lease Application area (MLA51/878)
For the entire 2017 and May 2018 Mineral Resource estimates, and the November 2018 Mineral Resource estimate
outside the MLA area, high resolution Digital Elevation Data was supplied by Landgate. The northern two thirds of
the elevation data is derived from ADS80 imagery flown September 2014. The data has a spacing of 5M and is the
most accurate available. The southern third is film camera derived 2005 10M grid, resampled to match it with the
2014 DEM. Filtering was applied and height changes are generally within 0.5M. Some height errors in the 2005 data
may be +/- 1.5M when measured against AHD but within the whole area of interest any relative errors will mostly be
no more than +/- 1M.
In 2015 a DGPS survey of hole collars and additional points was taken at conclusion of the drill program. Trepanier
compared the elevations the drillholes with the supplied DEM surface and found them to be within 1m accuracy.
Data spacing
and
distribution
Data spacing for reporting of Exploration
Results.
The 2018 RC drilling in Fault Block 17 has infilled areas of 260 m spaced drill lines to about 130m spaced drill lines,
with holes on 30 m centres on each line.
The closer spaced drilled areas of the deposit now have approximately 80m to 100m spacing by northing and 25m
to 30m spacing by easting. Occasionally these spacings are closer for some pairs of drillholes. Outside of the main
area of relatively close spaced drilling (approximately 7015400mN to 7016600mN), the drillhole spacing increases
to several hundred metres in the northing direction, but maintains roughly the same easting separation as the closer
spaced drilled area.
Whether the data spacing and distribution is
sufficient to establish the degree of
geological and grade continuity appropriate
for the Mineral Resource and Ore Reserve
estimation procedure(s) and classifications
applied.
The degree of geological and grade continuity demonstrated by the data density is sufficient to support the definition
of Mineral Resources and the associated classifications applied to the Mineral Resource estimate as defined under
the 2012 JORC Code. Variography studies have shown very little variance in the data for most of the estimated
variables and primary ranges in the order of several hundred metres.
Whether sample compositing has been
applied.
All assay results have been composited to one metre lengths before being used in the Mineral Resource estimate.
This was by far the most common sample interval for the diamond drillhole and RC drillhole data.

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.
The grid rotation is approximately 45oto 50omagnetic to the west, with the holes dipping approximately 60oto the
east. The drill fences are arranged along the average strike of the high grade mineralised horizon, which strikes
approximately 310oto 315omagnetic south of a line at 7015000mN and approximately 330omagnetic north of that
line. The mineralisation is interpreted to be moderate to steeply dipping, approximately tabular, with stratiform
bedding striking approximately north-south and dipping to the west. The drilling is exclusively conducted
perpendicular to the strike of the main mineralisation trend and dipping approximately 60oto the east, producing
approximate true thickness sample intervals through the mineralisation.
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 orientation of drilling with respect to mineralisation is not expected to introduce any sampling bias. Drillholes
intersect the mineralisation at an angle of approximately 90 degrees.
Sample security The measures taken to ensure sample
security.
Samples were collected onsite under supervision of a responsible geologist. The samples were then stored in lidded
core trays and closed with straps before being transported by road to the BV core shed in Perth (or other
laboratories for the historical data). RC chip samples were transported in bulk bags to the assay laboratory and the
remaining green bags are either still at site or stored in Perth.
RC and core samples were transported using only registered public transport companies. Sample dispatch sheets
were compared against received samples and any discrepancies reported and corrected.
Audits or
reviews
The results of any audits or reviews of
sampling techniques and data.
A review of the sampling techniques and data was completed by Mining Assets Pty Ltd (MASS) and Schwann
Consulting Pty Ltd (Schwann) in 2008 and by CSA in 2011. Neither found any material error. AMC also reviewed
the data in the course of preparing a Mineral Resource estimate in 2015. The database has been audited and rebuilt
by AVL and MRG in 2015. In 2017 geological data was revised after missing lithological data was sourced.
Geologica Pty Ltd concludes that the data integrity and consistency of the drillhole database shows sufficient quality
to support resource estimation.

The Gabanintha deposit was identified in the 1960’s by Mangore P/L and investigated with shallow
drilling, surface sampling and mapping.
In 1998, Drilling by Intermin Resources confirmed the down dip extent and strike continuation under cover
between outcrops of the vanadium bearing horizons.
Additional RC and initial diamond drilling was conducted by Greater Pacific NL and then AVL Australian
Vanadium up until 2015.
Previous Mineral Resource estimates have been completed for the deposit in 2001 (Mineral Engineering
Technical Services Pty Ltd (METS) and Bryan Smith Geosciences Pty Ltd. (BSG)), 2007 (Schwann), 2008
(MASS & Schwann), 2011 (CSA) and 2015 (AMC).
Geology Deposit type, geological setting and style of
mineralisation.
The Gabanintha Project is located approximately 40kms south of Meekatharra in Western Australia
and approximately 100kms along strike (north) of the Windimurra Vanadium Mine.
The mineralisation is hosted in the same geological unit as Windimurra, which is part of the northern
Murchison granite greenstone terrane in the north west Yilgarn Craton. The project lies within the
Gabanintha and Porlell Archaean greenstone sequence oriented approximately NW-SE and is
adjacent to the Meekatharra greenstone belt.
Locally the mineralisation is massive or bands of disseminated vanadiferous titano-magnetite
hosted within the gabbro. The mineralised package dips moderately to steeply to the west and is

The host sequence is disrupted by late stage dolerite and granite dykes and occasional east and
northeast -southwest trending faults with apparent minor offsets. The mineralisation ranges in
thickness from several metres to up to 20 to 30m in thickness.

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.
All the drilling was logged onto paper and has been transferred to a digital form and loaded into a Microsoft SQL
Server relational drillhole database using DataShedTMmanagement software. Logging information was reviewed
by the responsible geologist and database administrator prior to final load into the database. All assay results
were received as digital files, as well as the collar and survey data. These data were transferred directly from the
received files into the database. All other data collected for Gabanintha were recorded as Excel spreadsheets
prior to loading into SQL Server.
The data have been periodically checked by AVL personnel, the database administrator as well as the
personnel involved all previous Mineral Resource estimates for the project.
Data validation procedures used. The data validation was initially completed by the responsible geologist logging the core and marking up the
drillhole for assaying. The paper geological logs were transferred to Excel spreadsheets and compared with the
originals for error. Assay dispatch sheets were compared with the record of samples received by the assay
laboratories.
Normal data validation checks were completed on import to the SQL database. Data has also been checked
back against hard copy results and previous mines department reports to verify assays and logging intervals.
Both internal (AVL) and external (Schwann, MASS, CSA and AMC) validations were/are completed when data
was loaded into spatial software for geological interpretation and resource estimation. All data have been
checked for overlapping intervals, missing samples, FROM values greater than TO values, missing stratigraphy
or rock type codes, downhole survey deviations of ±10° in azimuth and ±5° in dip, assay values greater than or
less than expected values and several other possible error types. Furthermore, each assay record was examined
and mineral resource intervals were picked by the Competent Person.
QAQC data and reports have been checked by the database administrator, MRG. MASS & Schwann and CSA
both reported on the available QAQC data for Gabanintha.
Site visits Comment on any site visits undertaken by
the Competent Person and the outcome of
those visits.
The drill location was inspected by John Tyrrell of AMC in 2015 for the initial 2012 JORC resource estimation.
Consulting Geologist Brian Davis of Geologica Pty Ltd has visited all the Gabanintha project drilling sites since
2015 and has been familiar with the Gabanintha iron-titanium-vanadium orebody since 2006. The geology,
sampling, sample preparation and transport, data collection and storage procedures were all discussed and
reviewed with the responsible geologist for the 2015, 2017 and 2018 drilling. Visits to the BV laboratory and core
shed in Perth were used to add knowledge to aid in the preparation of this Mineral Resource Estimate.

Geological
interpretation
Confidence in (or conversely, the uncertainty
of) the geological interpretation of the mineral
deposit.
The Gabanintha Vanadium mineralisation lies along strike from the Windimurra Vanadium Mine and the oxidised
portion of the high-grade massive magnetite/martite mineralisation outcrops for almost 14km in the company held
lease area. Detailed mapping and mineralogical studies have been completed by company personnel and
contracted specialists between 2000 and 2015, as well as four separate drilling programmes to test the
mineralisation and continuity of the structures. These data and the relatively closely- spaced drilling has led to a
good understanding of the mineralisation controls.
The mineralisation is hosted within altered gabbros and is easy to visually identify by the magnetite/martite
content. The main high grade unit shows consistent thickness and grade along strike and down dip and has a
clearly defined sharp boundary. The lower grade disseminated bands also show good continuity, but their
boundaries are occasionally less easy to identify visually as they are more diffuse over a metre or so.
Nature of the data used and of any
assumptions made.
No assumptions are made regarding the input data.
The effect, if any, of alternative interpretations
on Mineral Resource estimation.
Alternative interpretations were considered in the current estimation and close comparison with the 2015
resource model was made to see the effect of the new density data and revised geology model. The continuity of
the low grade units, more closely defined from lithology logs is now better understood and the resulting
interpretation is more effective as a potential mining model. The near-surface alluvial and transported material
has also been more closely modelled in this estimation. The impact of the current interpretation as compared to
the previous interpretation would be a greater volume of low grade mineralisation and ahigher overall V2O5grade
for that mineralisation in the current estimate.
The use of geology in guiding and controlling
Mineral Resource estimation.
Geological observation has underpinned the resource estimation and geological model. The high grade
mineralisation domain has a clear and sharp boundary and has been tightly constrained by the interpreted
wireframe shapes. The low grade mineralisation is also constrained within wireframes, which are defined and
guided by visual (from core) and grade boundaries from assay results. The low grade mineralisation has been
defined as four sub-domains, which strike sub-parallel to the high grade domain. In addition there is a sub parallel
laterite zone and two transported zones above the top of bedrock surface.
The resource estimate is constrained by these wireframes.
Domains were also coded for oxide, transition and fresh, as well as above and below the alluvial and bedrock
surfaces.
The extents of the geological model were constrained by fault block boundaries. Geological boundaries were
extrapolated to the edges of these fault blocks, as indicated by geological continuity in the logging and the
magnetic geophysical data.

Criteria JORC Code Explanation Commentary
The factors affecting continuity both of grade
and geology.
Key factors that are likely to affect the continuity of grade are:

The thickness and presence of the high grade massive magnetite/martite unit, which to date has been very
consistent in both structural continuity and grade continuity.

The thickness and presence of the low grade banded and disseminated mineralisation along strike and
down dip. The low grade sub-domains are less consistent in their thickness along strike and down dip with
more pinching and swelling than for the high grade domain.

SW-NE oriented faulting occurs at a deposit scale and offsets the main orientation of the mineralisation.
These regional faults divide the deposit along strike into kilometer scale blocks. Internally the mineralised
blocks show very few signs of structural disturbance at the level of drilling.
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 massive magnetite/martite unit strikes approximately 14 km, is stratiform and ranges in thickness from less
than 10m to over 20m true thickness. The low grade mineralised units are sub-parallel to the high grade zone,
and also vary in thickness from less than 10m to over 20m. All of the units dip moderately to steeply towards the
west, with the exception of two predominantly alluvial units (domains 7and 8) and a laterite unit (domain 6) which
are flat lying.
All units outcrop at surface, but the low grade units are difficult to locate as they are more weathered and have a
less prominent surface expression than the high grade unit. The high and low grade units are currently
interpreted to have a depth extent of approximately 200m below surface. Mineralisation is currently open along
strike and at depth.
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.
Grade estimation was completed using ordinary kriging (OK) for the MineralResource estimate. SurpacTM
software was used to estimate grades for V2O5, TiO2, Fe2O3, SiO2, Al2O3, Cr2O3, Co, Cu, Ni, S and loss on
ignition (LOI) using parameters derived from statistical and variography studies. The majority of the variables
estimated have coefficients of variation of significantly less than 1.0, with Cr2O3being the exception.
Drillhole spacing varies from approximately 80 m to 100 m along strike by 25 m to 30 m down dip, to 500 m along
by 25 m to 30 m down dip. Drillhole sample data was flagged with numeric domain codes unique to each
mineralisation domain. Sample data was composited to 1 m downhole length and composites were terminated by
a change in domain or oxidation state coding.
No grade top cuts were applied to any of the estimated variables as statistical studies showed that there were
no extreme outliers present within any of the domain groupings.
Grade was estimated into separate mineralisation domains including a high grade bedrock domain, four low
grade bedrock domains and low grade alluvial and laterite domains. Each domain was further subdivided into a
fault block, and each fault block was assigned its own orientation ellipse for grade interpolation. Downhole
variography and directional variography were performed for all estimated variables for the high grade domain and
the grouped low grade domains. Grade continuity varied from hundreds of metres in the along strike directions to
sub-two hundred metres in the down-dip direction although the down-dip limitation is likely related to the extent of
drilling to date.

The availability of check estimates, previous
estimates and/or mine production records
and whether the Mineral Resource estimate
takes appropriate account of such data.
Prior to 2017, there had been five Mineral Resource estimates for the Gabanintha deposit. The first, in 2001
was a polygonal sectional estimate completed by METS & BSG. The subsequent models by Schwann (2007),
MASS & Schwann (2008) and CSA (2011) are kriged estimates.
AMC (2015) reviewed the geological interpretation of the most recent previous model (CSA 2011), but used a
new interpretation based on additional new drilling for the 2015 estimate.
In 2017 a complete review of the geological data, weathering profiles, magnetic intensity and topographic data
as well as incorporation of additional density data and more accurate modelling techniques resulted in a re-
interpreted mineral resource. No mining has occurred to date at Gabanintha, so there are no production
records.
Addition infill drilling and a single extensional diamond core holes have requested in minor adjustments to the
interpretation.
The assumptions made regarding recovery
of by-products.
Test work conducted by the company in 2015 identified the presence of sulphide hosted cobalt, nickel and
copper, specifically partitioned into the silicate phases of the massive titaniferous vanadiferous iron oxides
which make up the vanadium mineralization at Gabanintha. Subsequent test work has shown the ability to
recover a sulphide flotation concentrate containing between 3.8 % and 6.3% of combined base metals treating
the non-magnetic tailings produced as a result of the magnetic separation of a vanadium iron concentrate from
fresh massive magnetite. Further work is underway to evaluate the economic value of the concentrate by-
product. See ASX Announcements dated 22 May 2018 and 5 July 2018.
Estimation of deleterious elements or other
non-grade variables of economic
significance (e.g. sulphur for acid mine
drainage characterization).
Estimates were undertaken for Fe2O3, SiO2, TiO2, Al2O3, and LOI, which are non-commodity variables,but are
useful for determining recoveries and metallurgical performance of the treated material. EstimatedFe2O3%
grades were converted to Fe% grades in the final for reporting (Fe% = Fe2O3/1.4297).
Estimates were also undertaken for Cr2O3which is a potential deleterious element. The estimated Cr2O3%
grades were converted to Cr ppm grades (Cr ppm = (Cr2O3*10000)/1.4615).

Criteria JORC Code Explanation Commentary
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.
The Gabanintha block model uses a parent cell size of 40 m in northing, 10 m in easting and 5 m in RL. This
corresponds to approximately half the distance between drillholes in the northing and easting directions and
matches an assumed bench height in the RL direction. Accurate volume representation of the interpretation was
achieved.
Grade was estimated into parent cells, with all sub-cells receiving the same grade as their relevant parent
cell. Search ellipse dimensions and directions were adjusted for each fault block.
Three search passes were used for each estimate in each domain. The first search was 120m and allowed a
minimum of 8 composites and a maximum of 24 composites. For the second pass, the first pass search ranges
were expanded by 2 times. The third pass search ellipse dimensions were extended to a large distance to allow
remaining unfilled blocks to be estimated. A limit of 5 composites from a single drillhole was permitted on each
pass. In domains of limited data, these parameters were adjusted appropriately.
No selective mining units were considered in this estimate apart from an assumed five metre bench height for
open pit mining. Model block sizes were determined primarily by drillhole spacing and statistical analysis of the
effect of changing block sizes on the final estimates.
Any assumptions about correlation between
variables.
All elements within a domain used the same sample selection routine for block grade estimation. No co-kriging
was performed at Gabanintha, but correlation studies on the composite data showed very good correlation (0.8 or
above) between most variables, apart from Cr which has a correlation coefficient of
0.65 with V2O5.
Description of how the geological
interpretation was used to control the
resource estimates.
The geological interpretation is used to define the mineralisation, oxidation/transition/fresh and alluvial domains.
All of the domains are used as hard boundaries to select sample populations for variography and grade
estimation.
Discussion of basis for using or not using
grade cutting or capping.
Analysis showed that none of the domains had statistical outlier values that required top-cut values to be
applied.
The process of validation, the checking
process used, the comparison of model data
to drillhole data, and use of reconciliation
data if available.
Validation of the block model consisted of:

Volumetric comparison of the mineralisation wireframes to the block model volumes.

Visual comparison of estimated grades against composite grades.

Comparison of block model grades to the input data using swathe plots.
As no mining has taken place at Gabanintha to date, there is no reconciliation data available.
Moisture Whether the tonnages are estimated on a
dry basis or with natural moisture, and the
method of determination of the moisture
content.
All mineralisation tonnages are estimated on a dry basis. The moisture content in mineralisation is considered
very low.

Cut-off
parameters
The basis of the adopted cut-off grade(s) or
quality parameters applied.
A nominal 0.4% V2O5wireframed cut off for low grade and a nominal 0.7% V2O5wireframed cut off for high
grade has been used to report the Mineral Resource at Gabanintha. Consideration of previous estimates, as
well as the current mining, metallurgical and pricing assumptions, while not rigorous, suggest that the currently
interpreted mineralised material has a reasonable prospect for eventual economic extraction at these cut off
grades.
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.
AVL completed a mining Scoping Study in October 2016 for Gabanintha. The primary mining scenario being
considered is conventional open pit mining.
AVL has assumed, based on initial concept study work and the nearby presence of a similar project (Windimurra
mine site), that the Gabanintha deposit is amenable to open-pit mining methods.
In September 2018, AVL released a base case PFS which included key assumptions supporting a planned open
pit vanadium mining operation at Gabanintha.

Some preliminary sulphide concentrate recovery testing has been undertaken on selected 25kg fresh samples and
a 90kg fresh composite sample. These samples were ground to a P80of 106 µm and underwent wet magnetic
separation using a low intensity (1500 Gauss) magnetic separation drum. The non-magnetic stream was dried,
sub split and provided feed for sulphide flotation testwork. The flotation testing has been carried out at benchscale
using a scheme of typical sulphide flotation reagents. Rougher, scavenger and cleaner flotation has been tested
with one concentrate (test BC 4113/2) reground prior to cleaning.
The preliminary metallurgical investigation has demonstrated:
- The oxide, transitional and fresh materials are similar in comminution behavior and exhibit a moderate rock
competency and ball milling energy demand.
- The abrasiveness is considered low to moderate.
- A positive and predictable response to magnetic separation can be demonstrated from the fresh and transitional
material within the high-grade domain.The majority of vanadium exists within magnetic minerals which when
separated at a grind size P80of approximately 106 µm, generates a consistently high V2O5grade, low silica and
alumina grade concentrate.
- Oxidised material responds to magnetic separation, albeit at lower vanadium recovery and concentrate quality.
At this stage of metallurgical understanding a primary mill grinding to P80106 µm and application of magnetic
drum separation is considered a reasonable flowsheet concept to produce a vanadium rich concentrate
(approximately 1.4% V2O5) from material classified as oxide, transitional and fresh within the high-grade
domain.
Preliminary benchscale roast leach testwork has been undertaken using magnetic concentrate from
metallurgical sample Fr 2. Vanadium leach extractions of 79 to 86% have been determined in roasting for 110
minutes at approximately 1050oC testing a range of sodium carbonate addition rates (3 to 6%). Further
benchscale roast leach optimization testwork is in progress in preparation for pilot scale testing planned for
2019.
Given the indicated quality of the concentrate and the preliminary benchscale roast leach testwork results, it is
assumed that production of a saleable V2O5product would be achieved via a traditional roast, leach and
ammonium meta vanadate (AMV) flowsheet path. Similar flowsheets were applied in the treatment of magnetic
concentrate in Xstrata’s Windimurra refinery flowsheet in Western Australia and at Largo Resources Maracas
vanadium project in Bahia, Brazil. A pilot scale testwork program is planned for 2019 aimed at validating the
flowsheet and finalising engineering design criteria to support a definitive feasibility study.

Environmenta
l 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
greenfield 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.
Environmental studies are currently being undertaken for Pre-Feasibility work.
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.
Bulk density determinations (using the Archimedes’ method) were made on samples from 15 diamond
drillholes. Bulk density data from 313 direct core measurements were used to determine average densities for
each of the mineralisation and oxide/transition/fresh domains. Bulk Density was estimated for HG, LG, Alluvial
and waste material in Core taken to represent the main lithological units.
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.
The water immersion method was used for direct core measurements; all 231 of the latest measurements have
been done using sealed core, the previous 97 measurements were not wrapped. AMC’s observation of the core
indicates that observable porosity was not likely to be high for most of the core at the deposit.

Discuss assumptions for bulk density
estimates used in the evaluation process of
the different materials.
The average bulk density values for at Gabanintha are:
Domain
Oxidation State
Bulk Density
10 (high grade)
Oxide
3.39
10 (high grade)
Transition
3.71
10 (high grade)
Fresh
3.67
2-8 (low grade)
Oxide
2.13
2-8 (low grade)
Transition
2.20
2-8 (low grade)
Fresh
2.62
Alluvial
Oxide
2.63
(waste)
Oxide
2.02
(waste)
Fresh
2.45
All values are in t/m3.
Regressions used to determine bulk density based on iron content are as follows:

Oxide: BD = (0.0344 x Fe2O3%) + 0.9707

Transition: BD = (0.0472 x Fe2O3%) + 0.3701

Fresh: BD = (0.0325 x Fe2O3%) + 1.4716
The final bulk density used for reporting of the Gabanintha Mineral Resource is based on the regression as it
provides a more reliable local estimated bulk density.
Classification The basis for the classification of the Mineral
Resources into varying confidence
categories.
Classification for the Gabanintha Mineral Resource estimate is based upon continuity of geology, mineralisation
and grade, consideration of drillhole and density data spacing and quality, variography and estimation statistics
(number of samples used and estimation pass).
The current classification is considered valid for the global resource and applicable for the nominated grade
cut-offs.
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).
At Gabanintha, the central portion of the deposit is well drilled for a vanadium deposit, having a drillhole
spacing from a nominal 80 m to 100 m x 25 m to 30 m in northing and easting. The lower confidence areas of
the deposit have drillhole spacings ranging up to 500 m x 25 m to 30 m in northing and easting directions.
In general, the estimate has been classified as Measured Mineral Resource in an area restricted to the fresh
portion of the high-grade domain where the drillhole spacings are less than 80 to 100m in northing. Indicated
Mineral Resource material is generally restricted to the oxide high grade and oxide and fresh low grade in the
same area of relatively closely spaced drilling. Inferred Mineral Resource has been restricted to any other
material within the interpreted mineralisation wireframe volumes.
The background waste domain estimate has not been classified, due to very low possibility of economic
extraction and limited data.

Whether the result appropriately reflects the
Competent Person’s view of the deposit.
Geologica Pty Ltd and Trepanier Pty Ltd believe that the classification appropriately reflects their confidence in
the grade estimates and robustness of the interpretations.
Audits or
reviews
The results of any audits or reviews of
Mineral Resource estimates.
The current Mineral Resource estimate has not been audited.
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 resource classification represents the relative confidence in the resource estimate as determined by the
Competent Persons. Issues contributing to or detracting from that confidence are discussed above.
No quantitative approach has been conducted to determine the relative accuracy of the resource
estimate.
The Ordinary Kriged estimate is considered to be a global estimate with no further adjustments for Selective
Mining Unit (SMU) dimensions. Accurate mining scenarios are yet to be determined by mining studies.
No production data is available for comparison to the estimate.
The local accuracy of the resource is adequate for the expected use of the model in the mining studies.
Further investigation into bulk density determination and infill drilling will be required to further raise the level of
resource classification.
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 levels of confidence and accuracy relate to the global estimates of grade and tonnes for the deposit.
These statements of relative accuracy and
confidence of the estimate should be
compared with production data, where
available.
There has been no production from the Gabanintha deposit to date.
