ASX ANNOUNCEMENT
Infill drilling continues to demonstrate major polymetallic mineralisation at the Mulgine Trench deposit
Highlights
-
Drilling continues to intersect substantial thicknesses of tungsten mineralisation within a 160 to 260 metre wide zone at Mulgine Trench. Drilling has defined mineralised envelopes of:
-
266m at 0.11% WO3 and 215 ppm Mo from 2 metres in MMC445
-
252m at 0.11% WO3 and 475 ppm Mo from surface (0 metres) in MMC481
-
232m at 0.13% WO3 and 400 ppm Mo from 38 metres in MMC482
-
Drilling continued to intersect stronger molybdenum mineralisation associated within the 50m to 120m wide Lower Tungsten-Molybdenum Domain within the larger tungsten envelope. Better intersections include:
o52m at 0.21% WO3, 1010 ppm Mo from 192 metres in MMC482o64m at 0.12% WO3, 610 ppm Mo from 8 metres in MMC487 -
Upon completion of drilling, an updated Mineral Resource estimate is planned to be completed in April 2020.
Commentary
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.
On 19 December 2019, the Company announced the updated Mulgine Trench Mineral Resource estimate resulting in a major increase in contained tungsten and molybdenum and highlighting the significance of accessory minerals gold (850,000 ounces) and silver (35 million ounces) (refer ASX announcement 19 December 2019, “Major Mineral Resource Estimate Upgrade for Mulgine Trench Deposit”).
Since completion of reverse circulation (RC) drillholes used for the 2019 Mineral Resource estimate, Tungsten Mining has drilled an additional 145 RC holes for 27,128 metres . This announcement reports the latest assay results received by the Company from 22 January to 21 February 2020, representing 26 RC holes for 5,554 metres .
The Company is pleased to report that the latest assay results - subsequent to the Mineral Resource estimate released in December 2019, continue to be outstanding and demonstate intersections greater that 200 metres in true width.
Tungsten Mining’s CEO Craig Ferrier commented, “There is increasing confidence that the polymetallic mineralisation is remarkably consistent throughout the Trench deposit. In addition, the very substantial widths of mineralisation intersected in the initial phase of drilling are not only being confirmed but are now extending to a 260 metre wide zone. As this exciting phase of exploration comes to an end, we are looking forward to determining the scale of this significant tungsten poly-metallic resource compared to other world class tungsten deposits”.

Discussion of latest assay results
In July 2019, the Company commenced a phased drilling program as part of the Mt Mulgine Project PFS with the objective of upgrading the dominantly Inferred Mulgine Trench Mineral Resource estimate to a dominantly Indicated status.
Latest assay results from the 26 holes being reported here continue to intersect multiple tungsten-molybdenum intersections within a 160 to 260 metre envelope. Better holes that demonstrate the significance of mineralisation include MMC445, MMC481 and MMC482. These holes intersected multiple zones with minor internal waste forming overall mineralised envelopes of 266 metres at 0.11% WO3 and 215 ppm Mo from 2 metres, 252 metres at 0.11% WO3 and 475 ppm Mo from surface (0 metres) and 232 metres at 0.13% WO3 and 400 ppm Mo from 62 metres respectively. All three holes were drilled perpendicular to mineralisation and intervals represent true thicknesses (Figure 1).
Of the 5,554 metres from the 26 holes being reported, 3,728 metres fell within an intersection greater than 3 metres at 0.05% WO3 that, in aggregate terms, averaged 0.12% WO3, 310 ppm Mo, 0.15 ppm Au and 6 ppm Ag. This is consistent with the grade predicted by the 2019 Mineral Resource for blocks greater than 0.05% WO3.
Lower Tungsten-Molybdenum domain : in addition, the drilling continues to intersect significant polymetallic mineralisation associated with a lower Tungsten-Molybdenum domain that forms a 50 to 120 metre thick zone (Table 3 and Figure 2). Better holes from this zone include 52 metres at 0.21% WO3, 1,010 ppm Mo from 192 metres in MMC482 and 64 metres at 0.12% WO3, 610 ppm Mo from 8 metres in MMC487. Again, holes were drilled perpendicular to mineralisation and intervals represent true thicknesses.
A list of better holes from the latest assay results received with substantial zones of tungsten mineralisation from the 0.05% WO3 envelope displaying the bulk tonnage nature of Mulgine Trench is presented in Table 2. Better holes from the lower Tungsten-Molybdenum domain at a 200 ppm Mo lower cut-off are presented in Table 3. Better gold intersections greater than 0.10 ppm Au are reported in Table 4. A complete list of intersections greater than 3 metres at 0.05% WO3, 3 metres at 200 ppm Mo and 10 metres at 0.10 ppm Au are listed in Appendix 1, 2 and 3 respectively.
Mulgine Trench Mineral Resource
Resource consultants, Optiro Pty Ltd (Optiro) were engaged to update the Mulgine Trench Mineral Resource with results from the resource definition drilling commenced in July 2019. The update incorporated the drilling results from first 123 reverse circulation (RC) holes received to 22 November 2019. The revised Mineral Resource estimate for Mulgine Trench as of 19 December 2019 above a 0.05% WO3 reporting cut-off grade is as follows:

| Total | 207 | 0.11 | 230,000 | 272 | 56,000 | 0.13 | 850,000 | 5 | 35 |
Refer ASX Announcement 19 December 2019, “Major Mineral Resource Estimate Update for Mulgine Trench Deposit”. Note: Totals may differ from sum of individual numbers as numbers have been rounded in accordance with the Australian JORC code 2012 guidance on Mineral Resource reporting.
At a 0.05% WO3 cut-off grade and compared against the previous Mineral Resource estimate, drilling completed by the Company to 22 November 2019 resulted in a 189% increase in tonnes and an increase in contained metal of 97% in tungsten and 211% for molybdenum. In addition, gold and silver (accessory minerals) grades were estimated into the block model and this defined 850,000 ounces of gold and 35 million ounces of silver .
The extent of recovery of these accessory minerals is presently uncertain. Metallurgical test work to confirm recoveries for all minerals is in progress as part of the PFS programme and will be reported as the relevant information becomes available.

Figure 3. Location of Mulgine Hill and Mulgine Trench Mineral Resources.
The Mt Mulgine Project is located in the Murchison Region of Western Australia, approximately 350km north northeast of Perth. The Company owns 100% of the tungsten and molybdenum rights on a group of tenements that have been the subject of significant previous evaluation for tungsten and molybdenum. The Company also has the rights to all by-products from the mining of tungsten and molybdenum. Near surface Mineral Resources have been delineated at the Mulgine Trench and Mulgine Hill deposits, which have been the subject of ongoing evaluation by the Company (Figure 3).
Tungsten-molybdenum mineralisation at Mt Mulgine is associated with the Mulgine Granite - a high-level leucogranite forming a 2km stock that intrudes the Mulgine anticline (Figure 3). The granite intrudes a greenstone sequence composed of micaceous schists, amphibolite and talc-chlorite schist which were formerly metasediments, mafic and ultramafic rocks respectively. Tungsten-molybdenum mineralisation at Mulgine Trench is associated with altered and quartz veined mafic and ultramafic units that form a 160 metre to 260 metre thick zone over 1.4 kilometres of strike and dips shallowly towards the northwest.
The RC phase of resource definition RC drilling was completed on 21 February and it is anticipated a small number of diamond tails will be completed by the end of February. An updated Mineral Resource estimate using all new drilling data is planned to be prepared in April 2020. This updated block model will be used for pit optimisation and engineering studies as part of the PFS.

The information in this report that relates to Exploration Results and Data Quality is based on, and fairly represents, information and supporting documentation prepared by Peter Bleakley, who is a Member of the Australasian Institute of Mining and Metallurgy. Mr Bleakley is not a full-time employee of the company. Mr Bleakley is a consultant to the mining industry. Mr Bleakley has sufficient experience that is relevant to the style of mineralisation and type of deposit under consideration and to the activity being undertaken to qualify as a Competent Person as defined in the 2012 Edition of the ‘Australasian Code for Reporting of Exploration Results, Mineral Resources and Ore Reserves’. Mr Bleakley consents to the inclusion in the report of the matters based on his information in the form and context in which it appears.
The information in this report that relates to the Mulgine Trench Mineral Resource is extracted from the report titled ‘Major Mineral Resource Estimate Update for Mulgine Trench Deposit’ released to the ASX on 19 December 2019, available to view at www.tungstenmining.com. Tungsten Mining have drilled an additional 145 RC holes into the Mulgine Trench Mineral Resource. Interpretation of all new data is proceeding and a revised estimate is planned for release in April 2020. Other than the aforementioned review, the Company confirms that it is not aware of any new information or data that materially affects the information included in the ASX announcement and that all material assumptions and technical parameters underpinning the estimates in original ASX announcements continue to apply and have not materially changed. The Company confirms that the form and context in which the Competent Person's findings are presented have not been materially modified from the original ASX announcements.
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 4 - 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. During August 2016, TGN drilled 9 RC holes for 476 metres and one large diameter (PQ) diamond hole for 31.6 metres at Mulgine Trench to test tungsten mineralisation adjacent to and beneath the Bobby McGee pit In September 2018, TGN drilled 4 PQ diamond holes (528.2 m) into the Trench deposit to collect metallurgical samples and twin RC and diamond holes. From 12 July 2019 to present, the Company has drilled 279 RC holes for 47,809 metres. At the time of writing, Tungsten Mining had received results from 233 of the 279 RC holes and results reported in this announcement relate to 26 of these holes. |
| 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 a licenced surveyor using a Topcon GNSS with manufacturer’s specifications of +/- 10mm N,E and +/15mm Z. 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 tungsten mineralisation. Blanks were inserted into the sample stream behind high- grade samples to test contamination. 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 Given the style of mineralisation present at Mulgine Trench, Tungsten Mining ran an orientation survey to determine the acceptability of 2m sampling intervals. From this orientation work, it was concluded there was no discernible evidence that increasing the downhole sample interval from one to two metres materially impacts either accuracy or precision of the assay results. RC holes MMC265 – MMC291 and MMC301 – MMC309 were sampled at 1 m intervals from the cyclone and split using a cone splitter immediately beneath the cyclone to produce two representative 3 - 5 kg 1m-samples in calico bags. For all remaining holes, samples were split using a cone splitter to produce two representative 3 - 5 kg 2m-samples in calico bags. 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 Canning Vale, 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 279 RC drillholes with depths ranging from 6 to 310 m, averaging 171 m. RC drilling used a face-sampling hammer that produced a nominal 140 mm diameter hole. TGN have also completed 5 diamond PQ holes with depths ranging from 31.6 to 237 m, averaging 125 m. TGN diamond and RC holes were surveyed in-rods at 20 - 30 m intervals using a 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. All RC samples were dry and contamination would be minimal. 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 mineralisation to capture the geological data. During logging, part of the RC sample is washed, logged and placed into chip trays. During the 2019/2020 drilling programme, a second set of partially sieved material is stored in chip trays for mineral identification by a near-IR spectral scanner (PANalytical TerraSpec Halo). The washed chip trays are stored in sea containers on site and Halo chip trays stored at TGN’s Gnangara warehouse. 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. PQ metallurgical core was cut in half and then quartered. 1 metre samples of quarter core for PQ holes were submitted to Nagrom for XRF analysis. |
| 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, blanks and commercial standards. Duplicates, blanks and standards were inserted at intervals of one in 25. Geological logging and UV lamping was used to ensure duplicate and blank 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 or 2 m cone split samples at the rig. Repeatability in RC duplicate samples was found to be acceptable. Four PQ diamond holes and six RC hole have twined other RC and diamond drilling at Mulgine Trench. 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. |

| Criteria | JORC Code explanation Commentary |
|---|---|
| Whether sample sizes are appropriate to the grain size of the material being sampled. Assays from duplicate samples showed a low - moderate scatter (R20.82) for tungsten with no systematic bias. This is consistent with the style of mineralisation present, coarse grained scheelite associated with quartz veining. Molybdenum and silver results from duplicate samples showed good correlation with an R2of 0.94 and 0.92 respectively. Gold results from duplicate samples showed a higher degree of scatter with an R2of 0.63. This is interpreted to be related to the nugget effect or particulate nature of gold mineralisation at Mulgine Trench. 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 Mulgine Trench |
|
| 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. For Phase 1 drilling, a suite of 40 elements including tungsten, molybdenum and silver 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. Phase 2 holes (including results currently being reported ) were assayed for the tungsten suite by XRF, gold by fire assay and a reduced suite of elements including molybdenum and silver by Fused Bead Laser Ablation ICP-MS. |
| 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. A near-IR spectral scanner (PANalytical TerraSpec Halo) was utilised for mineral identification to assist in defining geometallurgical domains in the Phase 1 2019 drilling programme. Partially sieved material was collected, stored in chiptrays and scanned. |
|
| 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 blanks, 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 UV core photography and UV estimates for RC drilling against the drill database. |
| The use of twinned holes. TGN drilled four PQ diamond holes and 7 RC holes that twinned existing RC and diamond drilling at Mulgine Trench. Twin holes intersected similar widths and grades for mineralisation. High grade zones 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. Diamond logging is onto paper drill logs and data entered in Perth. 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. Holes drilled by TGN were picked up by a licenced surveyor using a Topcon GNSS with manufacturer’s specifications of +/- 10mm N,E and +/15mm Z. Downhole surveying of TGN holes was measured by the drill contractors using a 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 has been closed to a 40 metre by 40 metre pattern over areas of interest. Strike extensions are tested by 160 metres spaced section with 40 to 80 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 Trench was sufficient to define an Inferred Mineral Resource reported in December 2019. TGN have drilled an additional 145 holes into Mulgine Trench since this estimate. |
|
| Whether sample compositing has been applied. For non-mineralised intervals 1 m samples collected from the cyclone were composited into 5 m and later 6 m composite samples for RC drilling. Where composite samples have anomalous tungsten and/or molybdenum, the 1 m or 2 m cone split samples have been 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 perpendicular to the dominant vein geometry and mineralised stratigraphy. Holes drilled at -60 degree towards the southeast intersect dominant vein sets and stratigraphy at 90 degrees. |
| 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 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. |

Section 2: Reporting of Exploration Results
| Criteria | JORC Code explanation Commentary |
|---|---|
| Mineral tenement and land tenure status |
Type, reference name/number, location and ownership including agreements or material issues with third parties such as joint ventures, partnerships, overriding royalties, native title interests, historical sites, wilderness or national park and environmental settings. The Mulgine Trench prospect is located on Mining Lease M59/425-I covering an area of approximately 9.4 km2. 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 is 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. |
|
| 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 77 NQ/BQ diamond drillholes (8,703 m DD, 1,871 m pre-collars) in the 1970s and 1980s. In 2014, Minjar Ltd drilled 27 RC exploration hole (1,680 m) northwest of the Bobby McGee and 160 RC holes (5,712 m) for grade control in the Bobby McGee pit. Hazelwood Resources Ltd assayed these holes for their standard XRF tungsten suite. Gold Drilling In 1993, focus then turned onto gold exploration and multiple phases of dominantly RC drilling and minor diamond drilling was completed by numerous companies to present. A total of 342 RC holes (19,429 m) and 3 diamond holes (828 m) have been drilled to evaluate gold at Mulgine Trench. During mining, an additional 279 RC grade control holes (8,982 m) were drilled at the Camp and Highland Chief pits. Exploration drilling consisting of 422 RAB (11,374 m) holes was drilled across the Trench Deposit and strike extensions. TGN have conducted a thorough review of all drilling and sampling procedures. |

| Geology | Deposit type, geological setting and style of mineralisation. Mulgine Trench Stratigraphy for the Mulgine Trench deposit consists of a hangingwall amphibolites, the main mineralised horizon and footwall greisen of the Mulgine Granite. The mineralised horizon is a 160 to 260 metre thick zone that is delineated over 1.4 kilometres of strike and dips shallowly (25 – 40 degrees) towards the northwest. Tungsten and molybdenum mineralisation dominantly occurs as scheelite and molybdenite in foliation parallel veins or adjacent to vein margins or as coatings on fractures or disseminated in greisen units/veins. |
| 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. To highlight the extent of mineralisation present at Mulgine Trench, the 0.05% WO3mineralised envelope is reported in Table 1 that includes minor zones of internal waste (<10m) relative to the entire mineralised package. WO3and Mo grades are reported separately for intersections. Intersections were reported using a lower cut-off grade of 0.05% WO3. WO3and Mo grades are reported separately for intersections. No top cut and up to 2m of internal waste were included. A second set of intersections were reported using a lower cut- off grade of 200 ppm Mo. Again WO3and Mo grades are reported separately for intersections. No top cut and up to 2m of internal waste were included. A third set of intersections were reported using a lower cut-off grade of 0.10 ppm Au. WO3, Mo and Ag grades are reported separately for these intersections. Only intersections greater than 10m at 0.10 ppm Au were reported. No top cut and up to 2m of internal waste were included. |
| 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. |
|
| The assumptions used for any reporting of metal equivalent values should be clearly stated. Not applicable, no metal equivalents were quoted. |
|
| Relationship between mineralisation widths and intercept lengths |
These relationships are particularly important in the reporting of Exploration Results. If the geometry of the mineralisation with respect to the drill hole angle is known, its nature should be reported. If it is not known and only the down hole lengths are reported, there should be a clear statement to this effect (e.g. ‘down hole length, true width not known’). Inclined holes will intersect mineralisation at between 80° - 90°. True thickness will be between 90 to 100% of the intersection thickness for inclined holes. |
| Diagrams | Appropriate maps and sections (with scales) and tabulations of intercepts should be included for any significant discovery being reported These should include, but not be limited to a plan view of drill hole collar locations and appropriate sectional views. Refer to diagrams in the body of text. |
