Barrambie Gold Exploration Target

Highlights:

·      Maiden assessment completed on gold exploration potential at Barrambie using historical data from previous explorers;

·      Focus since Barrambie acquisition in 2003 has been on the titanium and vanadium deposit with gold potential not previously examined;

·      Barrambie Greenstone Belt ("BGB") historically produced 27,000 gold ounces at 27.8g/t;

·      Camp-scale gold potential with significant structural corridors identified;

·      Recent Neometals grab and rock chip sample assays range from 5.1g/t to 44g/t Au and are consistent with historical mined grades;

·      Exploration Target along the 40km strike of BGB within Neometals tenure is between 8Mt at an average grade of 1.3g/t Au and 10.5Mt at an average grade of 2.3g/t Au, for an implied 335,000 ounces to 775,000 ounces gold; and

·      Exploration Target considers a drill dataset across ten prospects, observed mineralogical characteristics, various geometries, dimensions and styles of known mineralisation and current understanding of structural and lithological controls on the location of mineralisation.

 

Sustainable process technology developer, Neometals Ltd (ASX: NMT & AIM: NMT) ("Neometals" or "the Company"), is pleased to provide an update on the potential gold endowment at the Company's 100% owned Barrambie Project ("Barrambie"), in Western Australia.

Barrambie is not only one of the world's highest-grade titanium deposits1 but is also highly prospective for gold mineralisation, with minimal gold exploration occurring since the 1970s. Neometals' ~706 km2 of tenure encompasses approximately 40km of strike of the BGB, the majority of which remains under-explored for gold (see Figure 1).

Figure 1 - Location of the Barrambie Project with respect to major Greenstone Belts of the Yilgarn.

A new geological model has been developed for the broader Yilgarn greenstone belt that contains the BGB ("GSB"), and reflects camp-scale gold prospectivity, that is, a multi-deposit portfolio of mineralisation of various dimensions and styles, such as those commonly found in the Yilgarn, including at the proximal of Gum Creek GSB, Meekatharra-Mount Magnet GSB and Sandstone GSB (see Figure 1 & Figure 2).

The model is framed around well-defined structural corridors and stratigraphic controls and is informed by substantial historical datasets, new structural interpretation of reprocessed geophysics, field observations and recent sampling conducted by Neometals (April 2024 see Appendix 3), which returned grades consistent with historic mined grades, including:

BGR03                    - 5.1 g/t Au

BGR15                    - 5.9 g/t Au

BGR05                    - 44.0 g/t Au

BGR43                    - 5.5 g/t Au

BGR06                    -17.3 g/t Au;


                                                                                                                                                                   


The historic dataset of over 1,500 drillholes (see Appendix 1 & 2) includes multiple, high-grade intersections including2:

Hole B194             - 4m at 6.1 g/t Au from 25

Hole I084               - 10m at 9.1 g/t Au from 10m

Hole BR064           - 6m at 11.8 g/t Au from 18m

Hole SG131           - 11m at 15.9 g/t Au from 69m

Hole I043               - 8m at 21.8 g/t Au from 8m



An Exploration Target has been calculated along the 40km strike of BGB within Neometals' tenure from between 8Mt, at an average grade of 1.3g/t Au, and 10.5Mt at an average grade of 2.3g/t Au, for an implied 335,000 ounces to 775,000 ounces gold.

Neometals Managing Director, Chris Reed, says:

"The excellent work of our technical team in compiling, validating and analysing historic exploration data has proven we have underestimated the gold potential of perhaps the only remaining greenstone terrain in the Yilgarn with no exploration effort in the last 20 years. It presents a rare opportunity to uncover a substantial gold camp, and we will explore the most effective strategy and corporate structure to capitalise on the gold potential. We will continue with our divestment strategy in relation to the titanium/vanadium resources."

Cautionary Statement

The Competent Person cautions that certain Exploration Results3 contained within this release have been extracted from historic DMIRS WAMEX4 annual reports by the previous historical operators. Further exploration and evaluation may affect confidence in these results under the JORC 2012 standards. Nothing has come to the attention of Neometals or its Competent Person that cause them to question the accuracy or reliability of the previously reported drill results and work.

The source reports (DMIRS WAMEX) are identified in the JORC Table 1 (Appendix 4) for all historical exploration reports used to quantify the potential gold endowment at Barrambie. These can be freely accessed by the public at https://geoview.dmp.wa.gov.au/GeoView using the unique A-number for each report.

The Company has undertaken desktop evaluation of the work completed. However, it has not comprehensively validated the results and therefore is not to be regarded as reporting, adopting, or endorsing these results.

The April 2024 grab/rock chips results (Appendix 3) included in this report were completed as a first pass validation of the historical grades compiled to date.

Background

The original Barrambie mining lease was granted in 1990 and Neometals has owned 100% of Barrambie since 2003, through its 100% owned subsidiary Australian Titanium Pty Ltd ("Australian Titanium"). Barrambie is located 750 kilometres north-east of Perth (see Figure 1).

The Company's historic and recent focus on vanadiferous titanomagnetite ("VTM") exploration has resulted in a lack of systematic, modern gold exploration along the Barrambie Greenstone Belt.

In January 2024, Neometals initiated a detailed search of the DMIRS WAMEX database that identified and acquired 111 historic reports relating to gold exploration. Data from the reports were compiled with existing digital data and a new gold exploration database developed. The database includes surface geochemical sampling and drill hole data. Surface maps and historical workings were also geo-registered and incorporated with the digital data to produce geological and numeric models.

The drillhole database compiled from publicly available data comprises AC, RAB, RC5 and some diamond drill holes but no diamond core or drill samples remain. Over 2,000 drill holes were compiled, 1,547 of which have gold assays and only 10% of these have been drilled to depths greater than 60m (see Figure 5 and Appendices 1 & 2). The historic drilling is spread across 10 prospects, however, most drilling is clustered around the two main gold centres, Ironclad and Barrambie Ranges, leaving much of Barrambie under-drilled and significant strike lengths totally untested by drilling.

   Exploration Report database.

Substantial historic surface geochemistry was also acquired. However, many gaps in the data leave the majority of the prospective greenstones ineffectively covered.

Existing geophysics data was reprocessed to highlight the potential structures associated with the known historical gold occurrences. This reprocessed data was then reinterpreted with a series of conjugate structural corridors being identified as being significant.

Comparison of the structural interpretation with the surface geochemical data and drilling data sets has revealed many data gaps and hence areas requiring follow-up exploration.

Exploration Target

The Exploration Target along the 40km strike of the BGB within Neometals tenure is between 8Mt at an average grade of 1.3g/t Au and 10.5Mt, at an average grade of 2.3g/t Au, for an implied 335k ounces to 775k ounces gold.

The Competent Person cautions that the potential quantity and grade of the Exploration Target is conceptual in nature, that there has been insufficient exploration to estimate a Mineral Resource and that it is uncertain if further exploration will result in the estimation of a Mineral Resource.

The Competent Person has relied on, and is basing this Exploration Target on, a combination of data listed below and detailed in this report and appendices:

·      geological setting of Barrambie within the under-explored BGB;

·      historic mining data which demonstrates the existence of high tenor gold mineralisation along the length of the greenstone belt;

·      historic drill data, albeit restricted in extent and at least partially ineffective, demonstrates continuity of Au mineralisation in multiple (10) locations;

·      historic surface geochemical data, albeit incomplete coverage, demonstrates Au anomalism along the length of the greenstone belt;

·      observed and recorded geological descriptions demonstrates Au mineralisation of various styles (shear/vein and stockwork) and lithological hosts (mafic intrusive and sediment);

·      recent grab and rock chip sampling (April 2024) which validates the tenor of gold mineralisation at the Barrambie Ranges and Sugarstone centres and demonstrate the potential of new, un-drilled, structures;

·      reprocessed geophysics and new structural interpretation showing multiple structural corridors and potential structural settings; and,

·      camp-scale geological/exploration concept.

The camp-scale concept describes exploration potential similar to that found in other greenstones belts of the Yilgarn, whereby multiple deposits of various magnitudes (in terms of contained Au ounces) contribute to a total endowment for Barrambie, simplified in Figure 3. Examples of camp-scale gold endowment within the Yilgarn include producing and advanced projects at historic gold mining centres at Gum Creek GSB, Meekatharra-Mount Magnet GSB and Sandstone GSB (see Figure 2).

The Exploration Target is based around a similar number of currently known prospects and their dimensions within top 200m below surface, noting the future targets are likely to include additional new prospects and depth extensions.

Neometals used the information outlined in this announcement to guide interpretations of drilled prospects and generate volumes with the assistance of implicit modelling software. For these deposits, assumptions of potential extensions to mineralisation were applied to derive the Exploration Target tonnage range. The quantity and quality of the drill assay dataset contained with the generated solids are insufficient to provide reliable grade estimates of future mineralisation. Hence assumptions of future grade ranges have been made.

Figure 4 - Barrambie Project tenure, simplified geology and historic production centers.

Geological Setting

The Project is situated within the Archaean BGB, which is a narrow, north-northwest trending greenstone belt in the northern Yilgarn Craton (see Figure 1, Figure 2 & Figure 4). The linear BGB is about 60 km long (40 km of which is contained in the Barrambie tenements) and attains a maximum width of about 4 km. It is flanked by banded gneiss and granitoids. The large layered, mafic intrusive Barrambie Igneous Complex (which hosts the Ti-V deposit) has intruded into and is conformable with the general trend of the enclosing Greenstone Belt. From aeromagnetic data and regional geological mapping, it appears that this layered sill complex extends over a distance of at least 25 km and varies in width from 500m to 1,700m.

The sill is comprised of anorthositic magnetite-bearing gabbros that intrude a sequence of metasediments, banded iron formation, metabasalts and metamorphosed felsic volcanics of the BGB. The metasediment unit forms the hanging-wall to the layered sill complex.

Exposure is poor due to deep weathering, masking by laterite, widespread cover of transported regolith (wind-blown and water-borne sandy and silty clay), laterite scree and colluvium. Where remnant laterite profiles occur on low hills, there is ferricrete capping over a strongly weathered material that extends down to depths of 70m. This factor had led to ineffective historical exploration.

Gold occurrences are generally associated with cross-cutting faults particularly proximal to gabbro contacts with the mafic metasediments to the east, but also with granites on the western side of the GSB (see Figure 4).  


Historic Gold Mining

Gold was discovered at Barrambie in 1905 during the construction of the Rabbit Proof Fence. Subsequent prospecting opened four main gold centres in the Barrambie area (see Figure 4):

·      Barrambie Centre (including the Barrambie Ranges historical underground gold mines)

·      Scheelite Centre6 (including the Dohertys gold mine)

·      Sugarstone Centre (including historic gold mines Ironclad, Sugarstone and Mystery)

·      Errolls Centre6 (including the Legacy gold mine)

Underground mining occurred predominantly in the first half of the 20th century with minor production extending through to 1985. The total production historically reported to the Mines Department from the four mining centres totalled 27,294 ounces of gold from 34,233 long tons of treated ore, at an average grade of 24.8g/t Au (Table 2).

 

______________________________

6 The Scheelite Centre & Errolls mining centre is not on Neometals tenements.

Mines Department reports note that gold mineralisation was structurally controlled with various styles present:

·      In north-south shear-zones at Barrambie Ranges, Sugarstone and Errolls;

·      Stockwork of quartz veins at Sugarstone and Barrambie centers. Mineralisation is associated with shears striking 120° and dipping steeply to the east, as well as shears striking 050-060° with flat to moderately northwest or southeast dips;

·      Infilled quartz vein stockworks within shear zones of the vanadium-titanium Barrambie Sill (at Sugarstone and Barrambie centers); and,

·      Infilled quartz-filled ferruginous saddle reef (or drag-fold) structures (Scheelite / Dohertys).

Historic Drilling data

Data for over 57,000 metres of drilling (not necessarily focused on gold targets) from over 2,000 drill holes has been compiled. Drilling data compiled from historic reports is summarised in Table 3 & Table 4 and Figure 5 and Appendix 1 & 2.

Data was acquired from historic WAMEX reports in digital and non-digital formats. RC and diamond drilling is restricted to more advanced gold prospects, such as Barrambie Ranges, Sugarstone-Mystery, Kismet, and Errolls.

Its significant to note that the majority of this drilling is less than 60m deep. It is also significant that the Project lacks the broad cover of RAB/AC drilling when compared to other greenstone belts.

The Competent Person cautions that the historical drill intercepts may not have been reported in accordance with the JORC Code or its precedents and considers these to be indicative of, but not absolute measures of, the presence and tenor of mineralisation.

Historic Surface Geochemical Data

All surface geochemical data were compiled and plotted from digital and non-digital sources (see Figure 6 and Table 5). Data consists of AUGER, BLEG, GRAB, LAG, ROCK, SOIL and STREAM sampling.

While surface geochemical coverage appears expansive, the Competent Person considers the main structures, particularly in the Barrambie Ranges and Ironclad/Sugarstone centres, to be under-surveyed. Similarly, field observations identify paleochannels west and east of the Barrambie VTM trend and historic soil sampling is considered ineffectual. The existing geochemical coverage is reduced by ~20% when historic sampling over paleochannels is removed.

Historical soils programs were restricted to historical tenement boundaries and not optimally located for potential gold structures.

Examples of Current Gold Prospects

The Mystery and Lupton's East prospects (at the Sugarstone mining center) have a strike length of 180m x 120m wide and is unconstrained along strike and down dip, plus with potential for parallel loads. Mystery was mined from 1908 to 1912 to a depth of 67m. It had five levels and Mines Department records indicate that it produced 4,428t for 3,413oz at an average grade of 23.6g/t au. Best drilling result is SG131 - 11m @ 15.9g/t Au from 69m (WAMEX report: A22584).

The Ironclad prospect (Sugarstone mining center) has a strike length of 600m x 50m wide and is interpreted as a series of stacked pods of mineralisation plunging to the northwest. Ironclad was a shallow underground mine completed in 1910 which Mines Department records indicate produced 22t for 10oz, at an average grade of 14.1g/t Au.

Best drilling result I043 - 8m @ 21.78g/t Au from 8m (WAMEX report: A37144) although it remains under-drilled below depths of 20m. Deeper intercepts requiring follow-up include (WAMEX report: A48813):

·      ICRC006 8m @ 5.11g/t Au from 88m;

·      ICRC004 9m @ 2.56g/t Au from 76m, and;

·      ICRC002 6m @ 2.55g/t Au from 74m.

Sugarstone was mined in 1909 from two separate lodes: one with a 30m long open pit to the west side and a second underground mine that went down 30 metres to the east of the pit.

Lost Chance prospect (Sugarstone mining center) has a strike length of 153m and is open along strike and down dip. Best drilling result BR064 - 6m @ 11.8g/t Au from 18m (WAMEX report: A16272).

Barrambie Ranges prospect (at the Barrambie mining center) is a shear hosted quartz vein in felsic volcanics east of the Barrambie Mining Lease M57/173-I. It remains poorly drilled along strike with best intercept of 4m at 6.06g/t (hole B194) yet to be followed-up.

The extent of historical workings suggest the northern area is less extensively mined underground. Mines Department records indicate production of 15,101oz at an average grade of 29.2g/t Au to a depth 100m from surface over 3 levels. Rock chips taken in April 2024 (see section below) support the grade and tenure of mineralisation reported to have been mined at Barrambie Ranges:

·      BGR05 - 44.0 g/t Au grab sample from the mullock dump of the Golden Hill shaft. This is indicative of the high grades mined underground;

·      BGR06 - 17.3 g/t Au an important sample as it is taken from in situ outcropping sheared basalt with no obvious quartz veining as would be expected for these grades. This sample shows that mineralisation extends beyond the quartz veining into the broader, host-shear zone.

Geophysics Reprocessing and Interpretation, Neometals 2024

In April 2024 Neometals had the existing geophysical datasets reprocessed. These were of good quality but had originally been processed to highlight the Barrambie VTM style of mineralisation. They were reprocessed to highlight the potential structures associated with the existing historical gold occurrences.

Once reprocessed, a consultant structural geologist completed a reinterpretation of the dataset. Note this interpretation is a first-pass undertaking and requires follow-up investigation and comparison with other datasets to increase the reliability of the location of interpreted features.

While gold mineralisation favours locally north-south oriented contacts/structures, the consultant identified a series of conjugate structural corridors with north, northwest and northeast trends (Figure 7). These features may represent long-lived structures and potential zones of reactivation and fluid flow during orogenesis, and thus are of interest for continued exploration, particularly in locations where the various corridors intersect.

Comparison of the structural interpretation with the surface geochemical data and inground drilling data sets shows how under explored the tenement package remains in terms of gold exploration.

Surface Sampling, Neometals 2024

In April 2024, grab and rock chip sampling was completed over several prospects, historical workings and structural targets to verify historic data and test under-explored trends (Figure 8). In total, 43 samples were collected with the descriptions and assay results reported in Appendix 3.

Significant assays include:

·      BGR01            - 2.4 g/t Au;

·      BGR02            - 3.67 g/t Au;

·      BGR03            - 5.1 g/t Au;

·      BGR05            - 44.0 g/t Au;

·      BGR06            - 17.3 g/t Au;

·      BGR15            - 5.9 g/t Au, and;

·      BGR43            - 5.5 g/t Au.

These rock chips successfully validate the tenor of gold mineralisation at the Barrambie Ranges and Sugarstone centres. BGR06 which returned 17.3 g/t Au from in situ un-veined, basalt-hosted shear, is of importance as it indicates the exploration potential of the broader shear zone. 

Rock chips BGR01 to BGR03 also show the potential of new, parallel, north westerly structures south of the Barrambie Ranges and Sugarstone centres where outcropping quartz veins and a shallow working occur which have never been followed-up with drilling or appropriate surface geochemical sampling.

Recommendations

The potential quantity and grade of the Exploration Target is conceptual in nature and will require a systematic exploration effort over number of years to verify and convert to a Mineral Resource. Initial exploration in the next term of the licence will focus on verification and extension of the historic data, including:

·      twin-hole drilling to verify the location and tenor of gold mineralisation identified in historic data;

·      extension of the surface geochemistry sampling to ensure key structural and lithological positions have appropriate coverage;

·      analysis for gold and pathfinder elements associated with large scale, orogenic gold mineralisation; and

·      follow-up drill testing of priority targets.

The Competent Person cautions that the potential quantity and grade of the Exploration Target is conceptual in nature, that there has been insufficient exploration to estimate a Mineral Resource, and that it is uncertain if further exploration will result in the estimation of a Mineral Resource.

The Competent Person further cautions that exploration data relied on for this Exploration Target are historic and have not or may not have been previously reported under the JORC Code or any of its precedents and considers that these are indicative and not absolute measures of the presence of gold mineralisation.

About Neometals

Neometals facilitates sustainable critical material supply chains and reduces the environmental burden of traditional mining in the global transition to a circular economy.

The Company is commercialising a portfolio of sustainable processing solutions that recycle and recover critical materials from high-value waste streams.

·      Neometals' core focus is its patented, Lithium-ion Battery ("LiB") Recycling technology (50% NMT), being commercialised in a 50:50 incorporated JV (Primobius GmbH) with 150-year-old German plant builder, SMS group GmbH. Primobius is supplying Mercedes-Benz a 2,500tpa recycling plant and operates its own LiB Disposal Service in Germany. Primobius' first 21,000tpa commercial plant will be offered to Stelco under an existing technology licence for North America.

Neometals is developing two advanced battery materials technologies for commercialisation under low-risk, low-capex technology licensing business models:

·      Lithium Chemicals (70% NMT) - Patented ELi™ electrolysis process, co-owned 30% by Mineral Resources Ltd, to produce battery quality lithium hydroxide from brine and/or hard-rock feedstocks at lowest quartile operating costs. Pilot scale test work and Engineering Cost Study update planned for completion in DecQ 2024; and

·      Vanadium Recovery (100% NMT) - Patent pending hydrometallurgical process to produce high-purity vanadium pentoxide from steelmaking by-product ("Slag") at lowest-quartile operating cost and carbon footprint.

Sampling techniques

Australian Titanium

Sampling activities include 43 grab and rock chip samples collected by Australian Titanium between 16-18 April 2024. Samples consisted of 1-3kg of mullock spoil or in situ outcrop sampled using a handheld geo pick hammer. Samples were collected in numbered calico bags and dispatched to Intertek Genalysis and assayed by fifty-gram fire assay with ICP-MS finish (FA50/MS) for Au, Pd and Pt.


Historical Drill Data (Prior to Australian Titanium)

Limited details about historical sampling methods not carried out by NEOMETALS were included in the WAMEX reports. Historical sampling referenced has been carried out by Samson Exploration NL, Regional Resources NL, Black Swan Gold Mines Ltd, Acclaim Exploration NL, Golden West Resources Ltd, Great Australian Resources NL, St Barbara Mines Limited, and Classic Minerals Ltd. Sampling included soil sampling, reverse circulation (RC) drilling, diamond drilling (DD), rotary air blast (RAB) drilling, aircore (AC) drilling, and unknown (UK) drilling.

 

RAB/AC sampling:

·      Samson Exploration 1987 (A21923, A22002, A22584, A22837, A23205, A23650, A23662, and A24458). Used spear sampling of 2m to 6m composite samples which were submitted to an appropriate lab for gold determination by Aqua Regia, such as Minlab.

·      Acclaim Exploration NL 1996 (Acclaim, A49171, A52165), One metre sample piles were sampled with a scoop as four metre composites of average weight 2.5kg. Samples were then transported to Perth and assayed; those above 0.2g/t Au were resampled at one metre intervals using the scoop and calico bags. Assayed at Genalysis by Aqua Regia Digest with unknown finish.

·      Dominion Mining Ltd 1992 (Dominion, A35163), drilled 92 RAB holes for 2,107m taking bottom of hole samples and 18 additional samples at the discretion of the geologist logging the holes. All samples were analysed for Au, As, Cu, Pb, Zn and Ni by Genalysis in Perth.

·      Samson Exploration NL 1993 (Samson, A40046). Holes were sampled at 1m intervals and 5m composite samples were sent to Australian Assay Laboratory to be assayed using Fire Assay, aqua regia digest, and carbon rod finish with 1ppb lower detection limit. 30g charges of 250g pulps were used for repeat assays.

·      Samson 1995 (A44301) One metre intervals were sampled and four metre composites collected. Anomalous composite samples (generally greater than 0.25ppm Au) were resampled at one metre and assayed at Minlabs Perth using aqua regia digest and AAS analysis for gold, arsenic and copper. A total of 1531 4m composite samples were collected with a further 119 one metre resamples taken.

·      Tindals Gold Mines NL 1995 (Tindals, A47011). Samples were laid out in 1m piles and 4m composite samples were collected. Samples were assayed at Minlabs Perth using aqua regia digest and AAS analysis for Au(ppb), V(ppm) and Cu(ppm).

·      Newcrest Mining Limited 1996 (Newcrest, A47114). 4m composite samples were taken for all holes and sent to Genalysis Laboratory Services for low level Au B/ETA (1ppb) and As and Cu B/AAS (ppm) analysis.

·      Great Australian Resources 1985 (GAR, A16272) and 1986 (A17137). Holes were sampled at 2m intervals using an unknown method. Samples were assayed for gold at Pilbara Labs using AAS and Aqua Regia digest. Samples with massive titano-martite were also assayed for Fe, V, Ti, Cr, Ni, Pt and Pd by fire assay.

·      St Barbara Mines Limited 1997 (St Barbara, A52148), 2000 (A61495), and 2001 (A62800). 6m composite samples were taken by unknown method. Samples were sent to SBML laboratory at Bluebird and assayed for gold by 50g Fire Assay with AAS finish. Samples that assayed >= 0.1ppm Au were re-assayed at 1m intervals.

RC sampling:

·      Miralga Mining NL 1986 (Miralga, A22658). Samples were collected at 1 metre intervals and riffle split to 2 kg. The samples were sent to ALS Perth for gold determination by Au50 Fire Assay analysis which has a 0.01ppm detection limit.

·      Samson 1987 - as for Aircore.

·      Black Swan Gold Mines Ltd 1992 (BSGM, A37144). Samples weighing around 1kg collected every metre from a mechanical splitter attached to the rig.

·      Acclaim 1996 (A52165) and 1997 (A48813). 1m samples were collected using a cyclone and splitter.

·      Golden West Resources 2008 (GWR, A78133). Samples were collected in 1m intervals using a cone splitter attached to the cyclone, residues were collected in plastic bags.

DD sampling:

·      Samson 1987 - RC pre-collars submitted at 1m intervals for Au (AAS) and the core was selectively sampled and intervals were cut into quarters. One quarter was sent for Au assay by Fire Assay and the remaining core kept.

 

Samson Exploration drilled several holes of unknown type in 1988 (A26799). No sampling information was available for these holes in the WAMEX report.

 

The Competent Person considers these methods of sampling to be appropriate for this style of exploration and consistent with industry practise at the time.

Drill sample recovery

Historical Drill Data (Prior to Australian Titanium)

Limited sample recovery and condition information has been found in the historical reports to date.

Logging

Historical Drill Data (Prior to Australian Titanium)

In some cases, original coordinates were only provided in unknown local grids. In these cases, MGA coordinates for holes were derived by georeferencing maps contained in the WAMEX reports and digitising the collars and it is expected that the accuracy of hole collar coordinates is within a few metres - roughly equivalent to GPS accuracy. Historic tenement boundaries and landmarks visible on aerial photography were used to georeference the maps. Minor corrections were then made where drill pads were still visible on aerial photography.

 

For reports that only contained handwritten logs, hole dips and azimuths were based on planned hole details, compass readings, or averages of survey tool measurements. These measurements are considered less reliable than modern downhole survey using north-seeking gyro.

 

·      Miralga 1986 consist of handwritten drill logs included as an appendix and are consistent with logging procedures of the time with a Hole ID, Co-ordinates, Rock description, a summary description, sample number, and logged metre interval with an end of hole depth recorded.

·      Samson 1987 consist of handwritten drill logs included as an appendix and are consistent with logging procedures of the time with a Hole ID, Co-ordinates, Rock description, a summary description, sample number, and logged metre interval with an end of hole depth recorded.

·      Acclaim 1997, Chip Logging: A representative selection of sample of each metre was logged using a binocular microscope onto a graphical log at 1 :200 scale. Special notes were made of the sample quality and approximate water depth. Original drill logs are consistent with logging procedures of the time with a Hole ID, Co-ordinates, Rock description, a summary description, sample number, and logged metre interval with an end of hole depth recorded.

·      Dominion 1991, 1992 and 1993 consist of handwritten drill logs included as an appendix and are consistent with RAB logging procedures of the time.

·      BSGM 1992 consist of handwritten drill logs included as an appendix and are consistent with RC and AC logging procedures of the time.

·      Samson 1993 and 1995 consist of handwritten drill and are consistent with RAB logging procedures of the time.

·      Tindals 1995 consist of handwritten drill logs and are consistent with RAB logging procedures of the time.

·      Newcrest 1996 consist of handwritten drill logs included as an appendix and are consistent with RAB logging procedures of the time with a Hole ID, Co-ordinates, rock description, a summary description, sample number, and logged metre interval with an end of hole depth recorded.

·      Acclaim 1996 consist of handwritten drill logs are consistent with RAB logging procedures of the time.

·      GWR 2008 included digital logs and are consistent with logging procedures of the time. Downhole survey data were generated by handheld compass, though the holes are all vertical, so this is not considered problematic.

·      GAR 1985 and 1986 (consist of handwritten drill logs and are consistent with RAB logging procedures of the time.

·      St Barbara 1997, 2000, and 2001 consist of handwritten drill logs and are consistent with RAB logging procedures of the time.

·      Samson 1988. No logging information was located for these holes. Hole collar coordinates were derived by georeferencing maps, and other hole details and assays were derived from cross sections in the report.

Sub-sampling techniques and sample preparation

 

 

 

Australian Titanium

 

Rock chip samples were collected in numbered calico bags and dispatched to the Intertek Genalysis for fifty-gram fire assay with ICP-MS finish (FA50/MS) for Au, Pd and Pt.

 

Historical Drill Data (Prior to Australian Titanium)

Limited details about historical sub-sampling was located.

·      Miralga 1986 samples were collected at 1 metre down hole intervals prior to being riffled on site to an assay sample weight of approximately 2kg. The sample residues for each metre were bagged, numbered, and left in rows at the drill site. Samples were dispatched to Australian Assay Laboratories in Perth for gold assay by 50g fire assay with 0.1ppm detection limit.

·      Samson 1987 reported samples were collected at one-metre intervals by spearing. Samples were dispatched to Minlab for gold determination by Aqua Regia, with a detection limit of 0.05ppm. Approximately 5% of the coarse rejects were submitted to Resource Development Laboratories of Perth for cross-checking by Fire Assay.

·      Acclaim 1997 reported that samples were collected at one-metre intervals by cyclone and splitter. Green bags caught the drill spoil passed through the cyclone for each metre. The resulting sample was tipped through the 87.5:12.5 multiple splitter. The sample residues were collected in numbered plastic UV bags and put in rows of 20, the 12.5 split was collected in numbered calico bags and weighed to ensure the sample weight did not exceed 3.3kg. If the weight exceeded this, it was re-split through a single stage splitter. Samples were dispatched to Ultratrace laboratories in Belmont Perth. Samples were dried in the calico bags then pulverised in a LM5 disc Mill. A 50g charge was then assayed for Au, Pt, and Pd by Aqua Regia digest with ICP-OES finish. A selection of mineralised samples from each hole were submitted to Genalysis for screen Fire Assay.

·      Dominion 1991 to 1993. End of hole samples were taken and dispatched to Genalysis Laboratory Services Pty Ltd. Samples were analysed for Au by Aqua Regia with AAS finish (B/ETA), and As, Cu, Sb, Bi, Mo, Pb, Zn and Ni by Aqua Regia digest with AAS finish (B/AAS)

·      BSGM 1992 holes were sampled every metre. No details on sampling methodology were included in the report. Samples were assayed for gold by Fire Assay at an unknown laboratory.

·      Samson 1993. Cuttings were collected at 1m intervals and laid out in lines with five-metre composites collected. Samples were sent to Australian Assay Laboratory and assayed using Fire recovery, Aqua Regia Digest, and Carbon Rod finish with a detection limit of 1ppb Au. 30g of 250g pulps were used for repeat assays.

·      Samson 1995. Cuttings were collected at 1m intervals and laid out in lines with four-metre composites collected. Samples were dispatched to Minlabs in Perth and assayed for Au, As, and Cu by Aqua Regia digest with AAS finish. Composite results >0.25ppm Au were resampled on a one-metre basis and assayed using the same method.

·      Tindals 1995. Cuttings were collected at 1m intervals and laid out in lines with four-metre composites collected. Samples were dispatched to Minlabs in Perth for Aqua Regia assay with AAS finish for gold (ppb), vanadium (ppm) and copper (ppm).

·      Newcrest 1996. Cuttings were collected at 1m intervals and laid out in lines with four-metre composites collected. Samples were dispatched to Genalysis Laboratory Services Pty Ltd and assayed for gold by Aqua Regia digest with AAS finish (B/ETA - 1ppb detection limit), and As and Cu by Aqua Regia digest with AAS finish (B/AAS - 5ppm and 1ppm detection limit respectively).

·      Acclaim 1996 to 1997. Samples were laid out in one-metre piles next to the hole with a pin marker placed in the first metre with the hole number. Samples were collected using an aluminium scoop for four-metre composites for an average 2.5kg sample. Samples were packed in poly-woven bags and taken to Key Transport Meekatharra for transport to Perth. Composite assay results > 0.2g/t Au were resampled at one-metre intervals using scoop and calico bags. Samples were sent to Genalysis Perth for Au analysis by Aqua Regia with a 1ppb detection limit.

·      GWR 2008. Samples were collected in 1m intervals using a cone splitter attached to the rig cyclone, residues were collected in plastic bags. Samples were dispatched to SGS laboratory for analysis of Au and As. Au was analysed by method FAA505 and As by method AAS21R.

·      GAR 1985 and 1986. Holes were sampled at 2m intervals using an unknown method. Samples were assayed for gold at Pilbara Labs using AAS and Aqua Regia digest. Samples with massive titano-martite were also assayed for Fe, V, Ti, Cr, Ni, Pt, and Pd by fire assay.

·      Samson drilled several holes of unknown type in 1988. No sampling information was available for these holes in the WAMEX report.

 

The Competent Person considers these methods of sub-sampling and assay to be appropriate for this style of exploration and consistent with industry practise at the time.

Quality of assay data and laboratory tests

Australian Titanium

To assure sample quality met the standards required by the Company and the mineralisation being sampled, the commercial lab's procedures and equipment were inspected and assessed for (among other things) maintenance, cleanliness, and appropriateness for the task. Company history and personnel experience were also assessed.

One CRM was included in the batch of samples submitted for rock chip analysis to Intertek Genalysis for assay. The lab also performed lab duplicate checks and inserted CRMs into the batch as part of their routine QAQC checks. The company analysed the performance of these duplicates and CRMs as results became available to ensure issues were detected and meaningful corrective actions implemented.

 

Historical Drill Data (Prior to Australian Titanium)

All historical samples are assumed to have been prepared and assayed by then industry standard techniques and methods.

Limited historical QAQC data were available in the WAMEX reports. Industry standard best practice is assumed in regard to QAQC

·      Miralga 1986 utilised Australian Assay Laboratories Group. Reports indicate the lab carried out repeats of primary samples however there is no indication of standards or blanks being used.

·      Samson 1987 samples were dispatched to Minlab for gold determination. Approximately 5% of the coarse rejects were submitted to Resource Development Laboratories of Perth for cross-checking by fire assay.

·      Acclaim 1997. Samples were dispatched to Ultratrace laboratories in Belmont Perth and subjected to a 50g aqua regia digest for Au, Pt and Pd using ICP-OES method. Detection levels are 1ppb, 5ppb and 2ppb respectively. Routine lab checking consisted of a random 6% of samples being analysed in duplicate. No details on any standard or blank samples for these Aqua Regia assays were in the WAMEX report. A selection of mineralised samples from each hole were also submitted to Genalysis for screen Fire Assay as validation of the Aqua Regia assays at Ultratrace. Standards and lab checks were included in the WAMEX report for the Fire assays.

·      Dominion 1991, 1992 and 1993. Samples were dispatched to Genalysis Laboratory Services Pty Ltd, reported assay results show the use of blanks, standards, and regular Au repeats.

·      BSGM 1992. Assay by Fire Assay. Unclear which lab was used. Sample result sheets show standards and duplicates were included in the assay methodology.

·      Samson 1993 and 1995. Samples were dispatched to Minlabs in Perth and assayed by Aqua Regia digest with AAS finish analysis for gold, arsenic, and copper. 1ppb detection limit for Au. Duplicates were completed for selected samples. No standards or blanks were recorded in the WAMEX reports.

·      Tindals 1995. Samples were dispatched to Minlabs in Perth for Aqua regia assay with AAS analysis for gold (ppb), vanadium (ppm) and copper (ppm). Reported assay results shows the use of regular Au repeats for QAQC by the lab. No standard or blank samples were recorded.

·      Newcrest 1996. Samples were dispatched to Genalysis Laboratory Services Pty Ltd for low level Au B/ETA (1ppb) and As and Cu B/ASS (ppm) analysis. Assay reports show no evidence of QAQC.

·      Acclaim 1996 and 1997. Samples were sent to Genalysis Perth for Aqua Regia analysis Au with a 1ppb detection limit.  Samples from the Cove prospect were also analysed for Au (1ppb), Cu (1ppm), Zn(1ppm), Ag (0.5ppm), Ni (2ppm) and Co (0.5ppm). Check assays included assaying 4% of a random selection of duplicate assays for all elements and well as up to 6% of selected gold repeats. No blanks were used. Some standards were inserted into batches.

·      GWR 2008. Samples were dispatched to SGS laboratory for analysis of Au and As. Au was analysed by Fire Assay method FAA505 and As by method AAS21R. Check assays include a selection of lab gold repeats.

·      GAR 1985 and 1986. Reports show lab duplicates were completed for selected samples. No record of standards or blanks was included in the reports.

·      Samson 1988 Selected samples were assayed in duplicate. No standards or blanks were reported.

·      St Barbara 1997, 2000, and 2001. Two standards were inserted into each lab batch and one in six samples were randomly selected for duplicate assay. Samples that assayed >0.5g/t Au were re-assayed in duplicate.

The Competent Person considers that the quality of the historical assay data is sufficient to provide an indication but absolute measure of the tenor of mineralisation sampled.

 

Verification of sampling and assaying

Australian Titanium

Geological data files were checked by the supervising geologist to ensure integrity of logs and metadata prior to submission to the database manager and upload to the hosted database. Assay files were received from the lab by the data base administrator, reviewed, and uploaded to the hosted database. The database hosting software includes automated error checking to flag any incorrect codes or numerical data outside of expected ranges.

After import into the database, an export was created and all data underwent a final check by the Senior Geologist and database manager.

Significant results were reviewed by multiple company geologists with reference to geological logs.

 

Historical data (drill data prior to Australian Titanium)

Historical data was compiled by experienced geologists from existing digital data sets downloaded from WAMEX or digitised from non-digital reports. Digitised datasets were visually validated in both two and three dimensions. Once validated complete datasets were compiled and uploaded to the hosted database.  The database hosting software includes automated error checking to flag any incorrect codes or numerical data outside of expected ranges.

 

Outside of any details included in the historical reports any details about data entry, verification, and storage protocols remains unknown for historical operators.

Location of data points

Australian Titanium

 

Samples were located in the field using hand- held GPS (accuracy 5m) in the UTM zone 50J coordinate system (Equivalent to MGA94 zone 50 projection).

 

Historical Drill Data (Prior to Australian Titanium)

Historical collars are recorded as being located by DGPS, GPS, compass, hip and chain measurement, or unknown methods. The original coordinates were recorded in local grid, AMG66, AMG84, or MGA94 coordinate systems. Coordinates were converted to MGA94 zone 50 using an automatic transformation in QGIS where possible. Where unknown local grids were used, maps from WAMEX reports were georeferenced and collars were digitised from the maps. In some cases, minor corrections to collar locations were used based on visibility of historic drill pads on aerial photography and satellite images. Little information has been provided in terms of downhole survey methods. Historical reports indicate a mix of compass, north-seeking gyro, Eastman single shot, and multi shot downhole cameras being used.

Data spacing and distribution

Historical Drill Data (Prior to Australian Titanium)

Based on the stages of exploration advancement for each of the project areas covered within the historical reports data spacing and distribution is considered appropriate for their style, stage, and level of understanding at the time. However, by current standards most of the drill data prior to 1990 are considered suboptimal.

The Competent Person considers that the spacing of the data is sufficient to provide an indication but absolute measure of the presence and location of mineralisation sampled and is suitable for geological targeting.

Orientation of data in relation to geological structure

Historical Drill Data (Prior to Australian Titanium)

Based on drill hole orientations and the regional aeromagnetics it appears that previous explorers attempted to drill holes perpendicular to the interpreted strike of the structures. The presence of historical workings would have aided them in orientating the drilling appropriately. A review of the historic data has determined that the orientation of drill holes was appropriate for the level of understanding at the time.

Sample security

Australian Titanium

Chain-of-custody protocols included supervision by Company employees of the samples while on site and transportation of samples to the lab. 

 

Historical Drill Data (Prior to Australian Titanium)

Sample security measures are unknown and generally not referenced in the reports.

Audits or reviews

No independent audits or reviews of sampling techniques and data were conducted.

Exploration done by other parties

The Company has owned and been exploring Barrambie for approximately 25 years.

The information below is based on annual technical reports submitted to DMIRS and available through the online WAMEX portal: Each report is identified by its unique A-number (e.g. Miralga Mining NL 1986 report A22658). The annual technical reports contain detailed context about the work completed and results achieved, including digital data for more recent reports.

Gold at Barrambie was discovered in 1905 during the construction of the Rabbit Proof Fence. Subsequent prospecting opened four main gold centres in the Barrambie area, namely:

1.    Barrambie Centre (including the Barrambie Gold Mine)

2.    Scheelite Centre* (including the Dohertys Gold Mine)

3.    Sugarstone Centre (including Sugarstone Gold Mine, Mystery Gold Mine)

4.    Errolls Centre* (including the Legacy Gold Mine)

The total production from the 4 mining centres mentioned above totalled 27,294 ounces of gold from 34,233 long tons of treated ore at an average grade of 24.8g/t Au.

·      Miralga 1986 focused exploration around the Legacy mine which was discovered in 1905. Surrounding the Legacy mine is the Three Star mine and the Inheritance mine, with reported combined production of 6,011.84 ounces of gold. Miralga completed 15 RC holes targeting the historic workings looking for strike and down dip extensions of the structures mined.

·      Samson 1987 completed soil sampling, costeaning, and drilling of 380 RAB holes, 152 RC holes and 2 diamond holes. Rock chips were taken from the old workings. Geological maps were produced at 1:10,000 scale. Samson defined three historic estimates of gold mineralisation:

Ironclad: 134,000t @ 3.2g/t Au (Sjerp, 1989)

Errolls: 28,000t @ 4.1g/t Au (Sjerp, 1989)

Dohertys: 6,500t @ 21.3g/t Au (Tomich, 1989)

The Competent Person cautions that these estimates were not estimated or reported in accordance with the JORC Code or any of its precedents and do not comprise Mineral Resource estimates but are indications of the presence of mineralisation.

·      Acclaim 1996 explored from the Errolls prospect south to the Barrambie Mining Lease, including the Sugarstone/Mystery and Ironclad prospects. Acclaim completed 13 RC holes for 1,421m to test the depth and strike of the Ironclad prospect and also completed geochemistry over the Floodway East prospect, following up on historic RAB drilling. Acclaim drilled 110 RAB holes for 5,928m to test Au anomalies from previous soil samples. They also completed 538 soil samples across the tenement to detect gold anomalism.

·      Dominion 1991 to 1993:

Exploration an area northeast of the Ironclad prospect consisted of 94 vertical RAB holes targeting the greenstone granite contact.

At Errolls North exploration consisted of lag sampling and 41 vertical RAB holes targeting Archean bedrock for bottom of hole Au and multielement analysis.

·      BSGM 1992 explored the Barrambie Range to feed the company's Whistler Gold operation, 50km to the east. Drilling focused on identifying mineralisation in the top 20m of the Ironclad prospect, comprising 125, 20m deep RC holes and further drilling at Errolls and Dohertys, which are off NEOMETALS tenure.

·      Samson:

In 1993, exploration included soil sampling, ground mag and RAB drilling. A total of 83 RAB holes were drilled targeting a shear structure

In 1995, work comprised 120 RAB holes testing several targets generated from 1993 ground magnetics and RAB geochemical anomalies.

·      Tindals 1995 exploration comprised 63 RAB holes drilled on the Barrambie Greenstone Belt assaying for As, As and Cu.

·      Newcrest 1996 explored the Errolls joint venture project where 63 RAB holes were drilled in the reporting period.

·      Acclaim 1996 121 RAB holes were drilled following up on Au in soil and rock-chip anomalies and 25 RC holes drilled testing Au mineralisation discovered at the Woodies and Silver Lining Prospects.

·      GWR 2008 drilled into the Dohertys prospect for 6 holes with the assay results reported later. Drilling intersected the Dohertys quartz vein and associated pyrite mineralisation.

·      Samson 1996 explored the Dohertys gold mine and Barrambie Ranges and completed aerial photography, gridding, sampling and mapping, stream sediment samplings, RAB drilling, RC drilling, diamond drilling, underground exploration, metallurgical sampling and dump sampling at Dohertys mine.

·      GAR 1985 and 1986 drilled 114 RAB holes for a total of 5,479m to test for gold potential at the Barrambie and Sugarstone mining centres and to test the gold potential of titano-martite bearing rocks.

·      St Barbara 1997, 2000 and 2001 explored the Kismet, Sugarstone, and Ironstone prospects and drilled 41 AC holes for 1,708m, and 15 RAB holes for 621m at the Kismet prospect to test granitoid contacts and old workings. 25 RAB holes for 868m were drilled to the east of Ironclad to test granitoid contacts.

Geology

The Barrambie gold project occurs within the Archaean Barrambie Greenstone Belt, which is a narrow, NNW-SSE trending greenstone belt in the northern Yilgarn Craton. The linear greenstone belt is about 60 km long and attains a maximum width of about 4 km. It is flanked by banded gneiss and granitoids. The Barrambie Sill is comprised of anorthositic magnetite-bearing gabbros that intrude a sequence of metasediments, banded iron formation, metabasalts and metamorphosed felsic volcanics of the Barrambie Greenstone Belt. The metasediment unit forms the hanging-wall to the layered sill complex.

All of the rocks of the Eastern Goldfields Superterrane have been subjected to the same post 2720 Ma structural history, comprising the D1 to D6 of Blewett and Czarnota (2010). The layered sequence is folded into an upright isoclinal anticline with attendant minor folds plunging to the northwest at 30 degrees. A Strong schistosity has developed as an axial plane fabric and is parallel or sub-parallel to the bedding.

Early shears trend from 345° to 360° with later faults trending 070° to 090°. Later second order faults trend 060°. Fault displacements range from a few metres to 400 metres.

Historically gold mineralisation was reported to occur mainly within the preserved eastern limb of the anticline and that the western limb was interpreted to have been consumed by intruding granites.

Historically it has been reported that the gold mineralisation occurs mainly within the preserved eastern limb for a strike length of 35km.

The mineralisation is structurally controlled. It occurs:

•     In N-S shear-zones (Barrambie Ranges, Sugarstone-Mystery, Kismet-Errolls).

•     Shear zones off a N-S strike will have mineralisation associated with a stockwork of quartz veins (Ironclad, Silver Lining, Old Mill). Orientation of the shear will dictate the dips of the shears. Shears that strike 120° tend to dip steeply to the east. Shears that strike 050-060° dip flatly to moderately northwest or southeast.

•     Infilled quartz vein stockworks within shear zones of the vanadium-titanium Barrambie Sill (White Dingo, Cove, Lost Chance).

•     Infilled quartz-filled ferruginous saddle reef (or drag-fold) structures (Scheelite Gold Mine, Dohertys).

Drill hole Information

All drill summary data material to the understanding of the exploration results has been included in the above announcement to which this table is attached.

Data aggregation methods

Intercepts tabulated in Appendix 2 are based on a minimum intercept of 10 gram*meters, lower cut off of 0.6g/t Au and a maximum internal dilution of 1m. The historic results reported consist of grade widths greater than 10ppm. No top assay cut was applied.

Relationship between mineralisation widths and intercept lengths

All holes were drilled perpendicular to the interpreted orientation of known, mineralised structures. Intercepts reported use down-hole lengths.

Diagrams

Representative geological and drill location plans and cross sections are included in the above announcement to which this table is attached.

Balanced reporting

It is not practical to report all historical exploration results from the Barrambie gold project. Selected historical intercepts have been re-reported by Neometals to highlight the prospectivity of the region. Full drillhole details can be found in the publicly available historical annual reports listed in this table.
