Neometals Ltd (ASX: NMT) (“Neometals”) is pleased to announce it has commenced pilot‐scale beneficiation test work as it advances development plans for Barrambie Titanium Deposit in WA, one of the world’s highest‐grade titanium deposits.
The Company’s project engineers, Sedgman Ltd, have updated the Pre‐feasibility Study (“PFS”) with optimisation test work results using the Neomet Process to produce Titanium Hydrolysate (TiO2.2H2O). The associated engineering study indicates the Neomet Process can be integrated with existing titanium pigment plants at minimal cost and modification. The advantages of the revised combined process are reduced operating cost, easier operations, higher purity final products and improved environmental footprint.
The original PFS, (see ASX announcement 25 August 2015) indicated potential operating costs of US$572/t titanium dioxide pigment. The current median price for high quality titanium dioxide pigment is US$2,950 per tonne on a CIF basis to USA (source: Industrial Minerals, 7 September 2017).
The revised Neomet Process will undergo pilot trials in late 2017. Neometals plans to licence the Neomet Process to titanium industry partners conditional on the entry into a long‐term, take‐or‐ pay offtake agreement for Barrambie titanium concentrates.

In parallel with the pilot evaluation of titanium hydrolysate production the Company will evaluate a fast‐track start‐up of Barrambie as a direct shipping operation. The ore would undergo toll‐ concentration a titaniferous magnetite concentrate in China for supply as feedstock to Chinese titanium pigment producers. On the 7[th] August 2017, the Chinese government announced the permanent closure of 89 ore processing companies in Sichuan province, constraining ilmenite production and limiting supply.
Drilling Results
In June and July twenty (20) holes were drilled within the TiO2 starter pit area to collect samples for metallurgical test work. Holes were drilled using diamond drilling techniques producing PQ core sample. Core was geologically logged on site, and shipped to Perth for cutting and quarter core sampling. Sampling was conducted on 1m intervals downhole for the first 40 metres only of each hole to correspond with the starter pit depth. Sampling of remainder of the core will commence this month.

A further twenty‐one (21) Resource Extension‐holes were drilled across three (3) traverses to test strike extensions of the Barrambie deposit as well as a structural repetition of the mineralised unit to the west of Barrambie (Virginia Hills). Drill traverses were located at Barrambie North, Ballanhoe Hills and Virginia Hills (see Figure 4 of Appendix A).
Resource extension‐holes were drilled using the reverse circulation (RC) technique by Challenge Drilling with samples collected on a per metre basis using face sampling hammers. The 1 metre composite samples were reduced in size using a cone splitter to produce one sample of 3 to 4 kg weight for each metre for assaying. It is estimated that greater than 95% of samples reported to the splitter device dry.

==> picture [86 x 70] intentionally omitted <==
Geological logging of both RC and diamond core was completed in sufficient detail to support reporting of exploration results. Logging was both qualitative and quantitative; full descriptions were recorded on standard logging forms of lithology, alteration, and oxidation as well as percentage estimates of alteration minerals, and veining.
Sample preparation and analysis was conducted by Intertek. Whole rock analysis of a standard iron ore suite was conducted by lithium borate fusion and ICP finish. The metallurgical drilling and resource extension drilling and assay details are set out at Table 3 and 4 of Appendix A: Supporting Information.

Metallurgical Pilot Test work
The Company has commenced the pilot scale beneficiation test work at Nagrom Metallurgical laboratories in Perth. The concentrate that will be produced will be supplied to Chinese titanium producers and for the pilot scale test work of the Neomet Process at the Company’s facility in Montreal, Canada.
Results of the beneficiation test work are expected in the December Quarter and hydrometallurgical test work is expected to commence late in the December Quarter. Both are key outputs for the commercialisation of the project.

The ferrovanadium titanium (Ti‐V‐Fe) deposit occurs within the Archaean Barrambie Greenstone Belt, 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. The Barrambie Sill extends over a distance of at least 25 km approximately half of which is covered by Neometal’s tenements where is varies in width from 500 m to 1700 m.
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 Barrambie Greenstone Belt. The metasediment unit forms the hanging‐wall to the layered sill complex.

JORC Table 1, Section 1, Sampling Techniques, and Data
| Criteria | Commentary |
|---|---|
| Sampling techniques | The Barrambie resource extension drilling comprises 21 reverse circulation (RC) holes sampled on 1 m intervals. Drill cuttings were collected in a cyclone, passed through a cone splitter to create a sample 3 to 4 kg in weight for assaying. Metallurgical drilling comprises 20 PQ core holes. Core was ¼ cut for assayingin 1metre lengths. |
| Drilling techniques | Resource extension drilling was conducted by reverse circulation (RC) technique. Metallurgical drilling was conducted by PQ coring technique. |
| Drill sample recovery | A qualitative logging code was used to record recovery for the recent RC and DD drilling. Recoveryof samples is considered to begood. |
| Logging | Geological logging of core and rock chips was carried out recording lithology, major minerals, oxidation, colour, texture, mineralisation, water and recovery. The logging was carried out in sufficient detail to meet the requirements of resource estimation and miningstudies. |
| Sub‐sampling techniques and samplepreparation |
All samples were dried, crushed to approximately 2mm, split and pulverised. |
| Quality of assay data and laboratorytests |
No field QAQC data was conducted by Neometals. Intertek Genalysis conducted their own internalQAQC,with no issues beingreported. |
| Verification of sampling and assaying |
Data was recorded in the field on paper logs and transferred to individual .xls files prior to merging with project database. No twin holes were drilled and no verification of significant intersections by independent laboratories has been undertaken. |
| Location of data points | Drill collar and azimuth were pegged in the field using GDA94 system byindependent surveyors. |
| Data spacing and distribution | Extension drill holes were spaced approximately on 30 metres centres across strike on three unrelated traverses. Metallurgical holes were spaced at 50m intervals alongthe strike of the Barrambie TiO2deposit. |
| Orientation of data in relation to geological structure |
Extension holes were drilled across strike to achieve unbiased sampling of the known mineralised zone. Metallurgical holes were drilled within plane of the Barrambie mineralisation. |
| Sample security | Samples were stored onsite and transported to the laboratory on a regular basis byNeometals employees. |
| Audits or reviews | No audits or reviews of sampling techniques and data have been conducted. |
JORC Table 1, Section 2, Reporting of Exploration Results
| Criteria | **Commentary ** |
|---|---|
| Mineral tenement and land tenure status |
The Barrambie mineralisation is within 100% owned granted mining lease M57/173 in the Eastern Murchison Goldfields. No known impediments exist to operate in the area. |
| Exploration done by other parties |
No relevant exploration has been completed by other parties to acknowledge or appraise at this time. |
| Geology | The ferrovanadium titanium (Ti‐V‐Fe) deposit 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 longand attains a maximum width of |
==> picture [204 x 58] intentionally omitted <==
==> picture [86 x 70] intentionally omitted <==
| about 4 km. It is flanked by banded gneiss and granitoids. The mineralisation is hosted within a large layered, mafic intrusive complex (the Barrambie Igneous Complex), which 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 into tenements to the north and south of M57/173. The layered sill varies in width from 500 m to 1700 m. 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 Barrambie Greenstone Belt. 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 70 m. Ti‐V‐Fe mineralisation occurs as bands of cumulate aggregations of vanadiferous magnetite (martite)‐ilmenite (leucoxene) in massive and disseminated layers and lenses. Within the tenement the layered deposit has been divided into five sections established at major fault offsets. Cross faults have displacements that range from a few metres to 400 m. The water table occurs at about 35 m below the surface (when measured where the lateriteprofile has been stripped). |
|
|---|---|
| Drill hole Information | See Tables and Figures in bodyof announcement. |
| Data aggregation methods | For the metallurgical drilling within the Barrambie high grade deposit, all assays for the portion of the hole assayed to date (0 to 40m) have been aggregated. Assays for the remainder of the holes (40 to 71m) are pending. For resource extension drilling, intervals that satisfy 2m at 5% TiO2have been reported. |
| Relationship between mineralisation widths and intercept lengths |
Resource extension holes have been drilled at an angle of 60 degrees from the horizontal toward grid west to achieve an approximate perpendicular intersection angle. Metallurgical holes were drilled entirely within the plane of the ore hence do not reflect true width of the orebody. |
| Diagrams | See body of announcement for Project geology, drill hole locations, schematicgeologyand drill cross sections. |
| Balanced reporting | All results have been reported. |
| Other substantive exploration data |
See ASX announcement 6 December 2013 for further information regarding the Barrambie deposit. With respect to the recent exploration being reported here, no other data is considered material or meaningful for these. |
| Further work | No further exploration work is planned for the immediate future in the Barrambie area. |
