Specialty metals explorer and developer Pan Asia Metals Limited (ASX: PAM) (‘PAM’ or ‘the Company’) is pleased to report that laboratory assays have been received for the drilling program at the Khao Soon Tungsten Project (KSTP) located in southern Thailand.
Pan Asia Metals’ Managing Director Paul Lock said: “We are pleased that the laboratory assays have returned strong results with a large number of intersections at greater than 0.5%, WO3 including 7.5m at 1.22% WO3. These are peer group leading results. At Than Pho West the results are in line with or better than the Exploration Target model, with the grades and geometries shaping up as open cut targets with the mineralisation being open at depth.
Further to our results it is pleasing to see the general buoyancy in the APT market, which is the reference price for tungsten. Fastmarkets MB recently reported that the APT price was $25,000-25,500 per tonne, the highest level since 2019. According to commentators the market is up due to tightness in the scrap and raw materials market and the demand side of the market is faced with the prospect that several large Chinese and Russian mines are reaching the end of their respective lives.
We believe Khao Soon will be one of the few new tungsten projects with the potential to work in the current price environment.”
Overview
KSTP is one of PAM’s key assets and a significant historical high-grade producer. Modern exploration has discovered potentially world-class, district scale tungsten mineralisation across numerous prospects. Previous diamond drilling by PAM has intersected robust widths and grades associated with strong surface anomalies, from which Exploration Targets have been estimated. The current drilling program seeks to test the Exploration Targets, with the ultimate aim of estimating Inferred Mineral Resources.
Target 2 and Than Pho West Assay Results are Very Encouraging
PAM has received assay results for holes KSDD024 to KSDD037 from the Target 2 (T2) and Than Pho West (TPW) prospects. The results support and generally enhance the previously reported spot hand-held XRF analysis on drill core and PAM notes a general increase in tungsten trioxide (WO3) concentrations.
Information on the drillholes and intersections of WO3 are included in Tables 1 and 2, respectively. Drillhole plans and cross sections are provided in this report.
Further details of the current and previous drilling programs can be found in Appendix 1, being JORC Table 1. Readers are also advised to refer to the following ASX announcements:

Target 2
Target 2 is defined by a large high tenor, tungsten in soil anomaly about 450m long and 150m wide (see Figure 1). Shallow drilling by previous explorers intersected tungsten mineralised laterite on the western side of the soil anomaly. Based upon the results of previous drilling and the large tungsten in soil anomaly, an Exploration Target of 6-12Mt @ 0.1-0.3% WO3 was estimated for Target 2, with details reported on October 8, 2020 in ASX announcement ‘Technical Reports for PAM Projects’. Readers are advised that in reference to the Exploration Target, the potential quantity and grade 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 drilling program at Target 2 had three main objectives:
Test an Induced Polarisation anomaly Test the large WO3 in soil anomaly Evaluate the Exploration Target defined at Target 2
Figure 1: Khao Soon Tungsten Project – T2 collar plan and geochemistry
A total of nine (9) holes have been drilled for an aggregate of 773.3m. Drilling results have confirmed robust near surface WO3 grades exist beneath much of the tungsten in soil anomaly which are generally in-line with the grades stated for the Exploration Target (see Figure 2).
Results for holes (KSDD023) drilled to test a deep Induced Polarisation and holes (KSDD030-031) drilled to test laterite hosted WO3 mineralisation west of the soil anomaly, have tended to downgrade these targets, although further drilling is required due to the wide spaced nature of previous and current drillholes at these targets.
Additional drilling is planned at Target 2 and will test the soil anomaly along strike to the northeast and southwest where it remains open. Further holes are also planned to test the mineralised zone down dip. The estimation of a Mineral Resource is contingent upon the results of future drilling.

Than Pho West (TPW)
The TPW prospect is defined by a large plus 1km long WO3 soil anomaly supported by rock-chips and subsequent drilling (see Figure 3). PAM has previously completed seven (7) widely spaced diamond core holes at TPW and defined near surface tungsten mineralisation over substantial widths.
Figure 3: Khao Soon Tungsten Project – TPW collar plan and geochemistry
Based upon the initial seven (7) drill holes an Exploration Target of 4-8Mt @ 0.2-0.4% WO3 was estimated, with details reported on October 8, 2020 in ASX announcement ‘PAM Projects – ‘Technical Reports’. Readers are advised that in reference to the Exploration Target, the potential quantity and grade 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 drilling program at TPW was designed as infill and extensional drilling to test the Exploration Target. Should the program be successful it may allow a Mineral Resource to be estimated. In the current program PAM has completed ten (10) holes at TPW (KSDD032-041) for a total of 828.2m. Results have been received for holes KSDD032 to KSDD037. Results for the remaining four holes are expected in the near term.
Drillholes KSDD032 and 033 were drilled as infill holes on a previously drilled section (see Figure 4). Both holes intersected wide zones with robust WO3 grades, averaging around 0.47% WO3 which is generally in-line or above those of previous drilling and the Exploration Target grade ranges. The mineralized zone as interpreted on this cross section attains a maximum true width of almost 60m, and extends at least 150m down dip and remains open.
Figure 4: Khao Soon Tungsten Project – TPW Cross Section CX938425
Drillholes KSDD034, 035 and 036 were drilled on the same section about 120m north of KSDD032/033 cross section (see Figure 5). These three holes have delineated a thick zone of tungsten mineralisation dipping about 35 degrees to the east and extending at least 200m down dip, where the zone remains open down dip of hole KSDD036, which intersected 27.5m @ 0.38% WO3 from 79.2m.
Figure 5: Khao Soon Tungsten Project – TPW Cross Section CX938530
This represents the deepest intersection at TPW to date. At its widest the true thickness of the mineralized zone on this section is interpreted to be approximately 63m.
The thickness and grade of the mineralized zone on this section is in line with the Exploration Target model.
Drillhole KSDD037 was drilled on a cross section about 120m south of the KSDD032/033 cross section (see Figure 6). KSDD037 intersected a 52m wide zone (true width), averaging 0.11% WO3 which remains open down dip. The thickness of this zone is in line with the Exploration Target model.
Figure 6: Khao Soon Tungsten Project – TPW Cross Section CX938300
Drillhole KSDD038 was drilled up-dip of KSDD037. PAM has no grade information from this hole due to a malfunction in the hand-held XRF. Laboratory assays for KSDD038 and subsequent holes 039, 040 and 041 are expected in the near term. PAM has also purchased a replacement hand-held XRF which should be delivered within three weeks.
Importantly most of the core intersections through the mineralized zones at TPW are PQ diameter. This larger diameter (85mm) core maximizes core recovery, compared to previous HQ diameter core (61mm), where recovery was variable in some of the mineralized zones. The PQ core also provides additional material for metallurgical test work.
The results support previous work, confirming a thick, shallow dipping mineralized zone with typical grades averaging between 0.2-0.5% WO3. These results serve to confirm and locally enhance the Exploration Target model.
Drilling at TPW is being undertaken at sufficient spacing that should enable a Mineral Resource estimate to be reported, subject to the success of the program and other factors that contribute to a Mineral Resource. Further drilling is planned at the TPW prospect and will seek to extend the mineralized zone along strike and down dip, along with local infill drilling.
PAM also has two other prospects where Exploration Targets have been estimated, Rabbit and Than Pho Ridge (see Figure 7). Further drilling is planned at these prospects to test the Exploration Targets with the aim of potentially delineating Mineral Resources. A large soil anomaly with robust WO3 grades occurs at the Last Hill prospect. This prospect will also be the focus of future drill testing.

Working Towards Inaugural Inferred Mineral Resource Estimates
As further laboratory results from the drilling program at Khao Soon are received they will be used to enhance geological interpretations and grade modelling with a view to updating the Exploration Target. At some prospects it is anticipated that PAM may be able to report an inaugural Inferred Mineral Resource estimate, subject to ongoing success.
Drilling at TPW is being undertaken at sufficient spacing that should enable a Mineral Resource estimate to be reported, subject to the success of the program and other factors that contribute to a Mineral Resource. Further drilling is planned at the TPW prospect and will seek to extend the mineralized zone along strike and down dip, along with local infill drilling.
PAM also has two other prospects where Exploration Targets have been estimated. The Rabbit and Than Pho Ridge prospects have a combined Exploration Target estimate of:
5 to 9 Million tonnes at between 0.2 and 0.4% WO3.
Details of the Exploration Targets were reported on October 8, 2020 in ASX announcement ‘Technical Reports for PAM Projects’. Readers are advised that in reference to the Exploration Target, the potential quantity and grade 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
Further drilling is planned at these prospects and will seek to test the Exploration Targets, with the aim of potentially delineating Mineral Resources.
A large soil anomaly with robust WO3 grades occurs at the Last Hill prospect. This will also be the focus of future drill testing.
Several other prospects at Khao Soon also require follow-up work, including drilling.
The Company looks forward to keeping Shareholders and the market updated on the drilling progress and results obtained from the planned drilling programs and other exploration at Khao Soon.

APPENDIX 1 - JORC Code, 2012 Edition – Table 1
Section 1 Sampling Techniques and Data
(Criteria in this section apply to all succeeding sections.)
Criteria
JORC Code explanation
Commentary
Sampling techniques
Nature and quality of sampling (eg 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. Include reference to measures taken to ensure sample representivity and the appropriate calibration of any measurement tools or systems used. 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 (eg ‘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 (eg submarine nodules) may warrant disclosure of detailed information. Samples are derived from diamond drilling conducted by Pan Asia (PAM) in late 2020, Pan Asia drill core is cut in half with one half being the sub-sample. These methods are considered appropriate. Routine analysis of a W Certified Reference Material (CRM) or ‘standards’ are inserted during XRF or laboratory analysis. Duplicates are also used as are internal laboratory QA/QC data reported.
Tungsten mineralization is hosted in laterite and weathered fault breccia transitioning into fresh rock. Broad zones are delineated above a lower cut-off of 0.05% WO3.
Drill core is cut in half or ¼ to collect mostly 0.5-1.5m individual sample lengths. Crushing to -2mm of the whole sample, then riffle or rotary cone splitting and pulverization of 0.5-1kg, from which a 100g sample was extracted for dispatch assay.
Drilling techniques
Drill type (eg core, reverse circulation, open-hole hammer, rotary air blast, auger, Bangka, sonic, etc) and details (eg core diameter, triple or standard tube, depth of diamond tails, face-sampling bit or other type, whether core is oriented and if so, by what method, etc). Diamond drilling was conducted using HQ, HQ triple tube or PQ/PQ triple tube. The core was not oriented.Drill sample recovery
Method of recording and assessing core and chip sample recoveries and results assessed. Measures taken to maximise sample recovery and ensure representative nature of the 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. Diamond core recovery is recorded for every drill run by measuring recovered solid core length and dividing that over the actual drilled length for that run expressed as %. Average core recoveries through the reported mineralised zones in each hole from 71%-92% and average about 80% HQ and PQ diameter, triple tube drilling is used to assist with maximising sample recovery especially in the weathered zone. Sample recovery of the mineralised zones excludes zones where no core and therefore no sample or assays are recorded. For diamond core drilling scatterplots of grade v recovery indicate that high W grades slightly concentrate with recoveries of less than 65%, potentially indicating some bias. However, lower to moderate W grades broadly occur across the broad range of recoveries.
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. Whether logging is qualitative or quantitative in nature. Core (or costean, channel, etc) photography.The total length and percentage of the relevant intersections logged. Core is geologically logged with salient features recorded to sufficient detail for the results being reported. Logging was qualitative. Colour, grain size, weathering, lithology type and salient comments are recorded. For drill core each tray is photographed wet and dry. Some cut core photos are also recorded. 100% of every hole is geologically logged For the diamond core logged intervals are around 30% of the total core drilled.
Sub-sampling techniques and sample preparation
If core, whether cut or sawn and whether quarter, half or all core taken. If non-core, whether riffled, tube sampled, rotary split, etc and whether sampled wet or dry.For all sample types, the nature, quality and appropriateness of the sample preparation technique.
Quality control procedures adopted for all sub-sampling stages to maximise representivity of samples.
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.
Whether sample sizes are appropriate to the grain size of the material being sampled.
Half or quarter core samples are cut with a large knife or broad chisel +/- hammer (when core soft enough) or cut with a diamond saw if too hard to hand-cut. The remaining half or 3/4 is retained in the core tray. The bagged sample is crushed to 100% passing -6mm or 80% passing 2mm. A 0.5-1kg sub-sample is then riffle or rotary spilt. The entire sample is then pulverized to 75% passing 75microns. For drill core samples 25-50% of the drilled interval is collected for sampling, and around 30-50% of this sample is pulverized to produce the pulp for assay. The methods described are considered appropriate and duplicate ¼ core samples show this. For the Pan Asia diamond drilling field duplicate/second-half or ¼ core sampling has been undertaken The sample/sub-sample sizes are considered appropriate for material being sampled. The pulverized sub-sample is also considered appropriate.
Quality of assay data and laboratory tests
The nature, quality and appropriateness of the assaying and laboratory procedures used and whether the technique is considered partial or total.
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.
Nature of quality control procedures adopted (eg standards, blanks, duplicates, external laboratory checks) and whether acceptable levels of accuracy (i.e lack of bias) and precision have been established.
For the PAM drilling, core samples were prepared by ALS in Vientiane, Laos and a 100g assay pulp sent to ALS in Brisbane for analysis. A lithium borate digestion digestion (ALS method ) was employed with analysis by ICP-MS (ALS method ME-MS85). Samples >1%W were analysed by XRF with sodium peroxide digestion (ALS method XRF-15b). These techniques employed are appropriate for tungsten analysis and are considered to be a total analysis technique.
For the PAM diamond drilling program certified W standards as pulps, a coarse blank and ¼ core duplicates were inserted at regular intervals into the appropriate sample stream. External laboratory checks have not been used. The QA/QC procedures indicate acceptable levels of accuracy and precision.
Verification of sampling and assaying
The verification of significant intersections by either independent or alternative company personnel.
The use of twinned holes. Documentation of primary data, data entry procedures, data verification, data storage (physical and electronic) protocols.
Discuss any adjustment to assay data. For the Pan Asia core drilling significant intersections have been verified by alternate company personnel, being the Chief Geologist and Exploration Geologist. Twinned holes not used. Primary data includes GPS co-ordinates, paper geological logs and sample data records. The hard copy records are checked against Excel spreadsheet files derived from digital data import or manual data entry. Adjustment of the data includes the conversion of W reported in lab analysis to WO3, by multiplying W by 1.261.
Location of data points
Accuracy and quality of surveys used to locate drill holes (collar and down-hole surveys), trenches, mine workings and other locations used in Mineral Resource estimation. Specification of the grid system used.Quality and adequacy of topographic control. Drill holes are surveyed by handheld GPS, accurate to about 2-5m in east and north.
The grid system used is WGS84, Zone 47. Northings and eastings are reported in meters. The topographic control used is Thailand national data. This is reported at 10m contour intervals. This data was checked against Google Earth elevations and those derived from GPS. The data is considered adequate for the purpose reported.
Data spacing and distribution
Data spacing for reporting of Exploration Results. 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. Whether sample compositing has been applied. Drillholes are typically being reported on sections from 70-125m apart, drill spacing on section is typically 60-80m
Sample compositing by way of weighted average grades at various cut-offs are being reported.
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. If the relationship between the drilling orientation and the orientation of key mineralised structures is considered to have introduced a sampling bias, this should be assessed and reported if material. The PAM diamond core drilling was mostly undertaken normal to the strike of possible of the mineralized zone, and in many cases normal or near normal to the dip of interpreted mineralized structures. No known relationship is known to existSample security
The measures taken to ensure sample security. The drill core is transported to the secure PAM processing facility. Core and samples are stored securely. Samples are delivered by reputable courier to Laos and then assay pulps delivered to Australia by reputable courier engaged by ALS.Audits or reviews
The results of any audits or reviews of sampling techniques and data. The sampling techniques for the PAM diamond drilling have been less formally assessed, aside from checks of assay accuracy/precision which provide acceptable comparisons. The sub-sampling and sample preparation techniques employed are industry standard. However audits or reviews have not been undertaken.

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 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 held as Special Prospecting Licences by Thai Mineral Venture Co. Limited, a 100% owned subsidiary of Pan Asia Metals under Special Prospecting Licence (TSPL) 1/2555 and TSPL 1/2562. They are located in the Nakhon Si Thammarat Province in southern Thailand. All of the areas subject to the SPL’s are accessible for exploration and potential devleopmeent.
The tenure is granted for 5 years from the date of issue. PAM is unaware of any impediments to obtaining a licence to operate in the area aside from the normal provisions that operate in Thailand, such as regulatory approvals in association with securing agreements with relevant landholders.
Exploration done by other parties
Acknowledgment and appraisal of exploration by other parties. TGF is the only company recorded to have done exploration, prior to PAM. PAM is reliant on the TGF data, having conducted appropriate due diligence and QA-QC studies. The TGF work has been conducted to an acceptable level.
Geology
Deposit type, geological setting and style of mineralisation. The deposit type is described as tungsten hosted in laterite and weathered to fresh breccia, probably associated with faulted hydrothermal breccia. The mineralization is located in the Main Range Province of the South East Asian Tin Tungsten Belt. Granitoid magmatism due to subduction and collision of microplates during the Early Triassic to Oligocene has generated some world-class tin - tungsten deposits in the region.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. If the exclusion of this information is justified on the basis that the information is not Material and this exclusion does not detract from the understanding of the report, the Competent Person should clearly explain why this is the case. Provided in textData aggregation methods
In reporting Exploration Results, weighting averaging techniques, maximum and/or minimum grade truncations (eg cutting of high grades) and cut-off grades are usually Material and should be stated. 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. The assumptions used for any reporting of metal equivalent values should be clearly stated. Bulk intersections are reported at > 0.05%WO3, and may rarely, allow for internal diliution of < 0.05%WO3.over 2m down hole. No top cut has been applied.Higher grade zones within the bulk lower grade zones are reported, at > 0.3% WO3 and allow for internal dilution of <0.3% WO3 up to 2m wide. Some higher cut-off grade zones are reported where material, generally >0.8% WO3. Some lower grade to anomalous WO3 zones are also reported where material.
Metal equivalents are not reported.
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 (eg ‘down hole length, true width not known’). For Pan Asia drill core, the results reported for most holes can be considered near to very near to true thickness. Mineralised zones are shallow dipping at 25-35 degrees, most holes are drilled normal to strike and normal to near normal to dip.
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. See attached report and Figures.Balanced reporting
Where comprehensive reporting of all Exploration Results is not practicable, representative reporting of both low and high grades and/or widths should be practiced to avoid misleading reporting of Exploration Results. All material drill results are reported.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. The surface areas containing and surrounding the reported drilling results have been mapped and soil sampling and rock-chip sampling has taken place. Results from these programs indicate extensive development of a ferruginous latertic zones and weatherd breccia zones at surface. These generally occur in association with large W in soil anomalies.Further work
The nature and scale of planned further work (eg tests for lateral extensions or depth extensions or large-scale step-out drilling). Diagrams clearly highlighting the areas of possible extensions, including the main geological interpretations and future drilling areas, provided this information is not commercially sensitive. The mineralization has generally been intersected in widely spaced holes in close proximity to surface. Infill drilling is planned as well as extensional drilling at depth. A metallurgical evaluation is also planned for the variety of oxidized and fresh mineralization intersected.
