Background
Australian tungsten developer, Tungsten Mining NL (ASX: TGN) (“TGN” or “the Company”) is pleased to report on the latest results from drilling at the Mt Mulgine Project. In the June Quarter, the Company completed 50 reverse circulation drill holes totalling 6,187 metres testing five targets around the Mulgine Hill deposit (Figure 1).
The objective of the drilling was to test potential high-grade tungsten-molybdenum mineralisation identified by historic drilling and a large coincident molybdenum-tungsten soil anomaly adjacent to the Mulgine Hill deposit. Drilling intersected significant tungstenmolybdenum mineralisation to the north, east and west of the Mulgine Hill deposit. Five holes were also drilled to investigate tungsten-molybdenum mineralisation beneath the Mulgine Hill deposit and these holes intersected zones of high-grade tungstenmolybdenum mineralisation. This announcement reports on assay results received by the Company from this drilling.
Tungsten Mining’s chairman Gary Lyons commented, “ We are pleased to have finalised and completed interpretation from the drill program testing targets adjacent to the Mulgine Hill deposit. These results have defined significant zones of molybdenum and tungsten mineralisation which may represent alternate development pathways. We are excited to explore these opportunities.”

Mulgine Hill East
In 2018, the Company conducted sterilisation drilling across a possible waste landform site at Mulgine Hill East and intersected significant zones of molybdenum-tungsten mineralisation over 620 metres of strike. Mineralisation was associated with strongly altered and quartz-veined mafic schists and greisen similar to that found at Mulgine Hill.
In the June 2023 quarter, the Company drilled 14 RC holes for 1834 metres to infill stronger zones of mineralisation to 80 metre by 40 metre drill spacing. Holes intersected molybdenum - tungsten mineralisation parallel to the Mulgine Granite contact over 520 metres of strike (Figure 2 and 3). Better intersections for molybdenum included 11 metres at 3300 ppm Mo from 56 metres and 5 metres at 3400 ppm Mo from 72 metres in MMC552. Tungsten mineralisation included zones up to 10 metres at 0.18% WO3 from 33 metres in MMC542 and 7 metres at 0.22% WO3 from 119 metres in MMC555 . Better intersections are listed in Tables 1 and 2 for molybdenum and tungsten respectively. For a complete list of intersections refer to Appendix 1 and 2.

Mulgine Hill North
In the June 2023 quarter, the Company drilled 11 RC holes for 1530 metres to test extensions to high-grade tungsten mineralisation at Mulgine Hill and anomalous molybdenum intersected by shallow historical RAB drilling. Drilling intersected two styles of mineralisation as follows:
-
Molybdenum (± tungsten) mineralisation hosted by quartz-veined mafics in the hangingwall to the Upper Greisen unit of Mulgine Hill.
-
Tungsten mineralisation hosted by the Upper Greisen that are extensions to Mulgine Hill mineralisation and which form continuous zone to the north and west of Mulgine Hill.
Drilling identified broad zones of molybdenum mineralization over 300 metres of strike including 16 metres at 4600 ppm Mo from 20 metres in MMC569 and 21 metres at 1700 ppm Mo from 34 metres in MMC564 (Figures 4 and 5).
Strike extensions to Mulgine Hill tungsten mineralisation included zones up to 10 metres at 0.14% WO3 from 45 metres in MMC562 and 10 metres at 0.25% WO3 from 118 metres in MMC563 . Best intersections are listed in Tables 3 and 4 for molybdenum and tungsten respectively. For a complete list of intersections refer to Appendix 1 and 2.

Mulgine Hill Footwall
During the June 2023 quarter the Company drilled five holes for 476 metres beneath the Main Zone at Mulgine Hill to investigate high-grade tungsten-molybdenum mineralisation intersected by drilling into the Mulgine Granite (Figure 7). Drilling at Mulgine Hill typically extended 10 to 20 metres beneath the Main Zone resulting in the Mulgine Granite is not being adequately drill tested. This implies that there is considerable potential for high-grade tungsten-molybdenum mineralisation immediately beneath the Mulgine Hill Mineral Resource.
All five holes intersected significant zones of tungsten-molybdenum mineralisation beneath the 2019 Mineral Resource estimate. Better intersections included 14 metres at 0.12% WO3 and 4400 ppm Mo from 57 metres in MMC583 and 20 metres at 0.07% WO3 and 1600 ppm Mo from 68 metres in MMC584 (Figure 8). Best intersections are listed in Tables 6 and 7 for molybdenum and tungsten respectively. For a complete list of intersections refer to Appendix 1 and 2.

Northern Soil Anomaly
During the June 2023 quarter the Company drilled 11 scout RC holes for 1117 metres to evaluate a large (1.6 km by 0.5 km) coincident molybdenum-tungsten soil anomaly northeast of the Mulgine Hill deposit (Figure 9). Drilling intersected fine to medium grained mafic/ultramafic units intruded by granitic dykes. Drilling was broad spaced with two holes intersecting significant molybdenum and/or tungsten mineralisation. The hole MMC549 intersected a 25 metre wide zone of anomalous molybdenum associated with quartz veined mafics adjacent to a granitic dyke. Preliminary 5m composite samples returned 10 metres at 500 ppm Mo from 25 metres and 5 metres at 2800 ppm Mo from 40 metres. The second hole MMC545, intersected tungsten and molybdenum mineralisation 175 metres north of Mulgine Hill. This mineralisation is associated with the Mulgine Granite contact indicating potential to extend mineralisation further north of the current drilling at Mulgine Hill.
Best intersections are listed in Tables 8 and 9 for molybdenum and tungsten respectively. For a complete list of intersections refer to Appendix 1 and 2.

About Tungsten Mining
Australian tungsten developer, Tungsten Mining NL is an Australian based resources company listed on the Australian Securities Exchange. The Company’s prime focus is the exploration and development of tungsten projects in Australia.
Tungsten (chemical symbol W), occurs naturally on Earth, not in its pure form but as a constituent of other minerals, only two of which support commercial extraction and processing - wolframite ((Fe, Mn) WO4) and scheelite (CaWO4).
Tungsten has the highest melting point of all elements except carbon – around 3400°C giving it excellent high temperature mechanical properties and the lowest expansion coefficient of all metals. Tungsten is a metal of considerable strategic importance, essential to modern industrial development (across aerospace and defence, electronics, automotive, extractive and construction sectors) with uses in cemented carbides, high-speed steels and super alloys, tungsten mill products and chemicals.
Through exploration and acquisition, the Company has established a globally significant tungsten resource inventory in its portfolio of advanced mineral projects across Australia. This provides the platform for the Company to become a major player within the global primary tungsten market through the development of lowcost tungsten concentrate production.

Appendix 3 - JORC Code Reporting Criteria
Section 1: Sampling Techniques and Data
| Criteria | JORC Code explanation Commentary |
|---|---|
| Sampling techniques | Nature and quality of sampling (e.g. cut channels, random chips, or specific specialised industry standard measurement tools appropriate to the minerals under investigation, such as down hole gamma sondes, or handheld XRF instruments, etc). These examples should not be taken as limiting the broad meaning of sampling. Mulgine Trench and Mulgine Hill are sampled using Reverse Circulation (RC) and Diamond Drilling (DD) over multiple drilling campaigns. The latest drilling campaign was completed by Tungsten Mining utilising RC drilling. A total of 50 Tungsten Mining RC (6187m) drillholes were drilled in the latest campaign and the majority of the holes were drilled at approximately 60⁰ - 90⁰. perpendicular to stratigraphy and mineralisation. |
| Include reference to measures taken to ensure sample representivity and the appropriate calibration of any measurement tools or systems used TGN drillhole collar locations were picked up by TGN personnel using a Hemisphere R120 DGPS receiver with sub- metre accuracy. Downhole surveying was measured by the drill contractors using a Champ North Seeking solid state gyroscopic system in the drill rods. Accuracy is ±0.75° for azimuth and ±0.15° for inclination. Certified standards were inserted into the sample sequences in according to TGN QAQC procedures. Duplicate samples were collected to check repeatability of sampling and variability or nugget effect for mineralisation. Results from this QAQC sampling were considered good. |
|
| Aspects of the determination of mineralisation that are Material to the Public Report. In cases where ‘industry standard’ work has been done this would be relatively simple (e.g. ‘reverse circulation drilling was used to obtain 1 m samples from which 3 kg was pulverised to produce a 30 g charge for fire assay’). In other cases more explanation may be required, such as where there is coarse gold that has inherent sampling problems. Unusual commodities or mineralisation types (e.g. submarine nodules) may warrant disclosure of detailed information The RC drilling crew collected 1 metre intervals from the cyclone and the sample was split using a cone splitter to produce two representative 2 – 4 kilogram samples in calico bags. The cone splitter was cleaned by hosing with pressurised air to eliminate sample contamination. One of the calico samples is for analysis and the second duplicate sample is retained as a reference sample for possible reanalysing / QAQC activities. The bulk reject material was collected at 1 m intervals from the cyclone and placed on the ground for geological logging. The cone splitter was cleaned by hosing with pressurised air to eliminate sample contamination. Two samples were collected; one is used for analysis and the other is retained as a reference or for possible re-analysing / QAQC activities. Samples from the current drilling programme were submitted to Bureau Veritas Minerals Pty Ltd of Canningvale, WA, for a standard XRF Tungsten Suite and 40 gram fire assay for gold analysis. A second suite of elements including silver and molybdenum were analysed by Laser Ablation ICP-MS. |

| 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). TGN completed 50 RC drillholes with depths ranging from 60 to 180 m, averaging 123 m. RC drilling used a face-sampling hammer that produced a nominal 140 mm diameter hole. TGN RC holes were surveyed in-rods at 30 m intervals using a Champ North Seeking gyroscopic probe. |
| Drill sample recovery |
Method of recording and assessing core and chip sample recoveries and results assessed RC and diamond recovery was visually assessed, recorded on drill logs and considered to be acceptable. |
| Measures taken to maximise sample recovery and ensure representative nature of the samples RC samples collected by TGN were visually checked for recovery, moisture and contamination. A cyclone and cone splitter was used to provide a uniform sample and these were routinely cleaned. The drill contractor blew out the hole at the beginning of each drill rod to remove excess water and maintain dry samples. |
|
| Whether a relationship exists between sample recovery and grade and whether sample bias may have occurred due to preferential loss/gain of fine/coarse material. Ground conditions for RC drilling were good and drilling returned consistent size samples. 96% of RC samples were dry and contamination would be minimal. Wet samples are noted down on sample sheets. No significant bias is expected, and any potential bias is not considered material at this stage. |

|---|---|
| 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. TGN uses specially designed drill logs for tungsten and molybdenum mineralisation to capture the geological data. During logging, part of the RC sample is washed, logged and placed into chip trays. The washed chip trays are stored in sea containers on site. All drill data is digitally captured and stored in a central database. |
| Whether logging is qualitative or quantitative in nature. Core (or costean, channel, etc) photography. RC chip logging included records of lithology, mineralogy, textures, oxidation state and colour. Key minerals associated with tungsten mineralisation and veining are recorded. |
|
| The total length and percentage of the relevant intersections logged All TGN drill holes were logged in full. |
|
| Sub-sampling techniques and sample preparation |
If core, whether cut or sawn and whether quarter, half or all core taken. No drill core collected during the current drill program. |
| If non-core, whether riffled, tube sampled, rotary split, etc and whether sampled wet or dry. TGN RC samples were collected on the rig by a cyclone. Material was split by a cone splitter immediately beneath the cyclone to produce two 3 - 5 kg samples. |
|
| For all sample types, the nature, quality and appropriateness of the sample preparation technique. Samples from the current drilling programme were submitted to Bureau Veritas Minerals Pty Ltd of Canning Vale, WA and dried, split if over 2.5 kg and pulverised in robotic vibrating disc pulveriser. |
|
| Quality control procedures adopted for all sub-sampling stages to maximise representivity of samples. TGN’s QAQC procedures included the insertion of field duplicates and commercial standards. Duplicates and standards were inserted at intervals of one in 25. Geological logging and UV lamping was used to ensure duplicate samples were from mineralised intervals. |
|
| 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. TGN inserted 1 in 25 RC field duplicates taken from 1 m cone split samples at the rig. Repeatability in RC duplicate samples was found to be excellent for tungsten and molybdenum. TGN have drilled PQ diamond holes and RC hole have twined other RC and diamond drilling at Mulgine Trench and MulgineHill. These holes intersected similar grade and thickness of WO3, Mo, Au and Ag mineralisation at target depths. Individual high grade zones did demonstrate the particulate or nuggetty nature of mineralisation present. |
|
| Whether sample sizes are appropriate to the grain size of the material being sampled. Assays from duplicate samples repeated well with no systematic bias for tungsten and molybdenum. The larger sample size of approximately 40 kg per metre collected by RC drilling is considered more appropriate than small diameter diamond holes and therefore sample sizes are considered to be acceptable to accurately represent the tungsten, molybdenum, silver and gold mineralisation present at Mt Mulgine. |

| 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. Tungsten Mining assays samples for a tungsten suite by XRF. XRF has proven to be a very accurate analytical technique for a wide range of base metals, trace elements and major constituents found in rocks and mineral materials. Glass fusion XRF is utilised for assaying, since it provides good accuracy and precision; it is suitable for analysis from very low levels up to very high levels. Gold was assayed by 40g charge lead collection fire assay with silver used as secondary collector. Fire assay is regarded as the preferred method for quantitative gold analysis. Molybdenum and silver plus 6 additional elements were assayed by Fused Bead Laser Ablation ICP-MS. The XRF disk is laser ablated and the gas formed is introduced to the Mass Spectrometer, providing an ideal platform for analysis. The Fused Bead Laser Ablation ICP-MS technique is total digestion of the sample achieved through the fusion process, so quantifiable elemental data is produced at detection limits that are equal if not better than acid digest techniques. |
| 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. A handheld magnetic susceptibility meter (KT-10) was used to measure magnetic susceptibility for every sample. Data is stored in the database. |
|
| 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. Field QAQC procedures for TGN sampling included the insertion of commercial standards and duplicates at the rate of one in 25 samples. Assay results have demonstrated acceptable levels of accuracy and precision. |
|
| Verification of sampling and assaying |
The verification of significant intersections by either independent or alternative company personnel. No independent personnel have verified intersections in drilling. TGN personnel have conducted a review of all assaying by visual inspection of standards, duplicates, UV and molybdenum estimates for RC drilling against the drill database. |
| The use of twinned holes. TGN drilled PQ diamond holes and RC holes that twinned existing RC and diamond drilling at Mulgine Trench and Mulgine Hill. Twin holes intersected similar widths and grades for mineralisation. Individual high grade intervals were however found to be variable or nuggety. |
|
| Documentation of primary data, data entry procedures, data verification, data storage (physical and electronic) protocols. Logging conducted by TGN takes place at the drilling site. Ruggedised computers are used to record the logging for RC samples. A set of standard Excel templates are used to capture the data. Data was validated on-site by the supervising geologist before being sent to Perth office. It was then loaded into Micromine and validated for logging codes, missing intervals, overlapping intervals, hole location and downhole surveying. Validated data is then loaded into a relational database for storage. |
|
| Discuss any adjustment to assay data. No adjustments were made, other than for values below the assay detection limit which have been entered as half of the detection limit. |
|
| 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. TGN drillhole collar locations were picked up by TGN personnel using a Hemisphere R120 DGPS receiver with sub- metre accuracy. Downhole surveying was measured by the drill contractors using a Champ North Seeking solid state gyroscopic system in the drill rods. Accuracy is ±0.75° for azimuth and ±0.15° for inclination. |
| Specification of the grid system used. Geocentric Datum of Australia 1994 (GDA94) - Zone 50. |
|
| Quality and adequacy of topographic control. High resolution aerial photography and digital elevation survey was flown by Geoimage Pty Ltd on 18 February 2018 with expected height accuracy of +/- 0.5 m. |

|---|---|
| Data spacing and distribution |
Data spacing for reporting of Exploration Results. Drill spacing varies from an 80 metre by 80 metre pattern over Mulgine Hill East, Mulgine Hill West and Mulgine Hill North. Drilling at Mulgine Hill was on 40 metre to 80 metre sections and the northern soil anomaly was tested by 240 metre spaced sections with 80 metre to 160 metre spaced holes. |
| 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 drill spacing at Mulgine Hill East, Mulgine Hill West and Mulgine Hill North is considered sufficient to determine target size. |
|
| Whether sample compositing has been applied. For non-mineralised intervals 1 metre samples collected from the cyclone were composited into 5 metre composite samples for RC drilling. Where composite samples have anomalous tungsten and/or molybdenum, the 1 m or 2 m cone split samples will be submitted for analysis. |
|
| 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 orientation of drilling was designed to intersect mineralisation as close as possible to perpendicular to the dominant vein geometry and mineralised stratigraphy. • Holes drilled at Mulgine Hill East and Mulgine Hill West are perpendicular to mineralisation. • Holes at Mulgine Hill North are drilled at 75⁰ to mineralisation for molybdenum zones and 45⁰ - 70⁰ to mineralisation for tungsten zones. • Holes at Northern Soil Anomaly are drilled 45⁰ - 75⁰ to stratigraphy. • The geometry of mineralisation at Mulgine Hill beneath the Main Zone is currently unknown. |
| 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. Structural logging of diamond core and structural data collected during geological mapping has confirmed that drill orientation did not introduce any bias regarding the orientation of mineralised veining. |
|
| Sample security | The measures taken to ensure sample security. Samples collected by TGN were securely sealed and stored on site and delivered by courier to the laboratory in Perth. Sample submissions forms used to track samples were emailed directly to the laboratory. |
| Audits or reviews | The results of any audits or reviews of sampling techniques and data. Internal Company audits for both historical and current Company drilling are carried out to ensure drilling and sampling techniques are consistent with industry standards, consistency of data is validated by Tungsten Mining while loading into the database. Any data which fails the database constraints and cannot be loaded is returned for validation. Global consistency is audited by plotting sections using the database and reconciling assays. During drilling the Company inserts standards, duplicates and blanks into the sample stream. These QAQC samples are periodically reviewed and any issues addressed. Tungsten Mining also conducted a thorough review of historical data that included checking of assay results, twinning of holes and checking drilling against historical reports. Any errors identified were corrected in the database. For TGN drilling, assay results are visually compared against UV estimates for tungsten and visual estimates for molybdenum. |

| Mineral tenement and land tenure status |
Type, reference name/number, location and ownership including agreements or material issues with third parties such as joint ventures, partnerships, overriding royalties, native title interests, historical sites, wilderness or national park and environmental settings. The prospects are located on Mining Lease M59/425-I and M59/386-I covering an area of approximately 9.4 km2and 8.4 km2respectively. TGN has 100% of the mineral rights for tungsten and molybdenum and to all by-products from the mining of tungsten and molybdenum. The current registered holder of the tenement is Minjar Gold Pty Ltd. The normal Western Australian state royalties apply. The Federal Court has determined that Native Title does not exist over the area of M59/425-I in relation to Badamia claim (Federal Court # WAD6123/1998). M59/425-I and M59/386-I are located on former pastoral lease ‘Warriedar Station’ which has been purchased by the State Government and now forms part of the Karara Rangeland Park. Other operating mines are also located within the Park boundary. |
| The security of the tenure held at the time of reporting along with any known impediments to obtaining a licence to operate in the area. The tenements are in good standing at the time of reporting. Mid-West Tungsten Pty Ltd, a wholly owned subsidiary of Tungsten Mining NL, holds a consent caveat over tenement M59/425-I and M59/386-I. |

| Exploration done by other parties |
Acknowledgment and appraisal of exploration by other parties. Tungsten Drilling Drilling initially focused on tungsten mineralisation with Minefields and ANZECO drilling NQ/BQ diamond drillholes in the 1970s and 1980s. Gold Drilling In 1993, focus then turned onto gold exploration and multiple phases of dominantly RC drilling and minor diamond drilling were completed by numerous companies to present. TGN have conducted a thorough review of all drilling and sampling procedures. |

| Geology | Deposit type, geological setting and style of mineralisation. Tungsten-molybdenum mineralisation at Mt Mulgine is associated with the Mulgine Granite - a high-level leucogranite forming a 2km stock intruding the Mulgine anticline. The intrusion is associated with intense hydrothermal alteration with late stage fluids containing tungsten, molybdenum, gold, silver, bismuth and fluorite. The Mulgine Hill Deposit occurs along the northern margin of the Mulgine Granite. The main mineralised zone (Main Zone) is associated with the Upper Greisen/Mafic Schist contact. Tungsten mineralization at Mulgine Hill occurs as scheelite hosted by quartz and greisen veins in the Mafic Schist unit (phlogopite-quartz-pyrite schist) and as scheelite in quartz veins or as disseminated scheelite within the greisen (quartz-muscovite rock). Overlying the main zone are multiple less continuous mineralized zones hosted by the greisen. In addition, molybdenum – tungsten mineralization is present beneath the Main Zone associated with quartz veined greisenised granite in the Mulgine Granite. Recent drilling by Tungsten Mining has identified significant tungsten-molybdenum mineralisation associated with the Mulgine Granite contact to the east and south of Mulgine Hill. Tungsten Mining drilling at Mulgine Hill East identified broad zones of shallow southerly dipping molybdenum – tungsten mineralisation associated with potassic alteration and quartz veining in mafic units. Alteration and veining is similar to that at Mulgine Hill. At Mulgine Hill North and West, the current drilling program intersected similar zones of tungsten mineralization on strike extensions of the Upper Greisen/Mafic Schist contact. At Mulgine Hill North, in the hangingwall to the Upper Greisen molybdenum mineralization is associated with quartz-veined mafic units. |
| Drill hole Information |
A summary of all information material to the understanding of the exploration results including a tabulation of the following information for all Material drill holes: • easting and northing of the drill hole collar • elevation or RL (Reduced Level – elevation above sea level in metres) of the drill hole collar • dip and azimuth of the hole • down hole length and interception depth • hole length. Collar data for drilling is included in Appendix A. |
| Data aggregation methods |
In reporting Exploration Results, weighting averaging techniques, maximum and/or minimum grade truncations (e.g. cutting of high grades) and cut-off grades are usually Material and should be stated. For prospect that are dominantly tungsten, intersections are reported for all intervals greater than 3m at 0.05% WO3using a lower cut-off grade 0.05% WO3, no top cut grade and up to 2m of internal waste. For prospects where there is significant molybdenum present (>500 ppm Mo), intersections were also reported using a lower cut-off grade 500 ppm Mo. No top cut and up to 2m of internal waste was used. |
| Where aggregate intercepts incorporate short lengths of high grade results and longer lengths of low grade results, the procedure used for such aggregation should be stated and some typical examples of such aggregations should be shown in detail. For reporting of tungsten intersections, all assays >1.0% WO3 are reported beneath the relevant intersection. Interval zones of waste up to 2m wide are included in intersections provided the adjacent zone and waste are >0.05% WO3. For reporting of molybdenum intersections, all assays 10,000 ppm (>1.0% Mo) are reported beneath the relevant intersection. Interval zones of waste up to 2m wide are included in intersections provided the adjacent zone and waste are >500 ppm Mo. |

Other substantive exploration data
Other exploration data, if meaningful and material, should be reported including (but not limited to): geological observations; geophysical survey results; geochemical survey results; bulk samples – size and method of treatment; metallurgical test results; bulk density, groundwater, geotechnical and rock characteristics; potential deleterious or contaminating substances.
Mulgine Hill
Mineralogical and metallurgical studies on the Hill deposit showed scheelite was well liberated below 0.3mm and gave high recoveries using x-ray ore sorting, gravity separation tables and flotation. X-ray Ore sorting to remove gangue material prior to milling, gravity treatment and flotation has the potential to reduce the processing plant footprint, capital and operating costs.
Cleaning of the final concentrate to achieve the required grade was achieved using flotation at ambient temperature. Evidence gathered to date shows that no metallurgical problems are expected to affect the overall viability of the project.
These results reinforce the metallurgical test work completed in the 1970s and 1980s that showed that the ore as represented by the samples tested was readily concentrated to a 65% WO3 concentrate at an estimated recovery of 80%.
Mulgine Hill East
The mineralisation intersected in the current drilling program, is representative of the mineralisation tested in prior testwork.
Testwork demonstrated ore amenability to sulphide flotation to concentrate the molybdenum and copper minerals. No further work has been completed to produce a saleable molybdenum or copper concentrate from this material.
