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 final four holes of a drilling program conducted at the Than Pho West prospect (TPW) within the Khao Soon Tungsten Project (KSTP) in southern Thailand. This brings an end to the Priority One drilling program at Khao Soon which saw the completion of nineteen (19) holes for a total of 1601.5m.
Pan Asia Metals Managing Director Paul Lock said: “We are pleased to see the final assays for this phase of drilling come through and reinforce previous drilling results and the Exploration Target model. We are particularly pleased with the way the Than Pho West prospect is shaping up, drilling has confirmed a thick, shallow dipping mineralized zone with true widths up 63m supported by numerous very high grade intersections over good widths. In a low cost environment such as SE Asia, and in close proximity to advanced industrial centres, the Khao Soon Tungsten Project is shaping up to be a peer group leader both in grade and size.”
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 Mineral Resources.
PAM has received assay results for holes KSDD038 to KSDD041 from the TPW prospect. The results support and generally enhance the previously reported spot hand-held XRF analysis of drill core and PAM notes a general increase in tungsten trioxide (WO3) concentrations.

Than Pho West (TPW)
The TPW prospect is defined by a large plus 1km long WO3 in soil anomaly supported by rockchips and subsequent drilling (see Figure 1). PAM had previously completed seven (7) widely spaced diamond core holes at TPW and defined near surface tungsten mineralisation over substantial widths.

==> picture [55 x 55] intentionally omitted <==
Based upon the initial 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. Further drilling is planned.
Drillholes KSDD032 and 033 were drilled as infill holes on a previously drilled section (see Figure 2). Both holes intersected wide zones with robust WO3 grades, averaging around 0.47%WO3, which is generally 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, extends at least 150m down dip and remains open.

==> picture [55 x 55] intentionally omitted <==
Drillholes KSDD034, 035 and 036 were drilled on the same section about 120m north of KSDD032/033 cross section (see Figure 1). 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. This represents the deepest intersection at TPW to date. At it’s widest the true thickness of the mineralized zone on this section is interpreted to be approximately 63m (see Figure 3). The thickness and grade of the mineralized zone on this section is in-line with the Exploration Target model.

==> picture [55 x 55] intentionally omitted <==
Drillholes KSDD037 and 038 were drilled on a cross section about 120m south of the KSDD032/033 cross section (see Figure 1). 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. Drillhole KSDD038 was drilled up-dip of KSDD037 (see Figure 4).
==> picture [426 x 362] intentionally omitted <==
Figure 4: Khao Soon Tungsten Project – TPW Cross Section 938300mN
Results for KSDD038 correspond with the broad lower grade zone intersected down-dip in hole KSDD037. The 10m wide zone @ 0.39% WO3 in KSDD038 corresponds with a highergrade zone at the base of the KSDD037 intersection. Hole KSDD038 was extended to 170m to test an Induced Polarisation “chargeability” anomaly possibly related to mineralisation. The target area was found to contain unmineralized pyritic siltstone.

==> picture [55 x 55] intentionally omitted <==
Hole KSDD039 was drilled down-dip of KSDD004. Results for KSDD039 indicate the 46.5m wide zone with an average grade of 0.32% WO3. This zone confirms the down-dip extension of mineralisation in hole KSDD004 which returned similar WO3 grades (see Figure 5). The mineralized zone in KSDD039 remains open down dip.

==> picture [55 x 55] intentionally omitted <==
Hole KSDD040 was drilled toward the northern of TPW on a previously undrilled section. The results indicate a strong zone of mineralisation, with an intersection of 20.1m @ 0.74% WO3 from 47.9m. Lower grades were also intersected from surface (see Figure 6).
==> picture [426 x 362] intentionally omitted <==

7
==> picture [55 x 55] intentionally omitted <==
Hole KSDD041 was drilled on a previously undrilled sections about 90m south of KSDD040. KSDD041 intersected 15.1m @ 0.10% WO3 from 35.9m (see Figure 7). It is worth noting that on this section the surface soil anomaly seems to reduce in WO3 grade and size, potentially indicating some local control to mineralisation.
==> picture [426 x 362] intentionally omitted <==
Figure 7: Khao Soon Tungsten Project – TPW Cross Section 938760mN
Importantly most of the core intersections through the mineralized zones at TPW are PQ diameter. This larger diameter (85mm) core maximizes core recovery and 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 at TPW.
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.

Target 2
Target 2 is defined by a large high tenor, tungsten in soil anomaly about 450m long and 150m wide (see Figure 8).
==> picture [426 x 503] intentionally omitted <==

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
9
==> picture [55 x 55] intentionally omitted <==
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 ‘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 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.
A total of nine (9) holes (KSDD023-031) have been drilled for an aggregate of 773.3m. Results from the drilling program 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 9). The mineralised zone is interpreted to dip about 25 degrees to the south-east.

Figure 9: Khao Soon Tungsten Project – T2 Cross Section KSDD023-025-026

==> picture [55 x 55] intentionally omitted <==
Results for holes (KSDD023), drilled to test a deep Induced Polarisation chargeability anomaly, and holes (KSDD031-031) drilled to test laterite hosted WO3 mineralisation west of the soil anomaly have tended to downgrade these targets. Although further drilling is required at Target 2 the results of the recent drilling would appear to downgrade the Exploration Target.
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.
At the Khao Soon project PAM has two other prospects where Exploration Targets have been estimated, Rabbit and Than Pho Ridge. 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.

==> picture [55 x 55] intentionally omitted <==
The Rabbit prospect is located approximately 3 km north of the T2 prospect and is defined by a 1.3 km long zone of strongly elevated tungsten in soil geochemistry and rock-chips (see Figure 10). Smaller satellite prospects also exist to the north and east of the main trend.

==> picture [55 x 55] intentionally omitted <==
The Than Pho Ridge prospect is located approximately 500m east of Than Pho West. (see Figure 1) The prospect area is defined by a 1.3 km long soil geochemistry and rock chip anomaly, in association with old workings and the occurrence of weathered tungsten rich breccia. PAM has conducted broad-spaced diamond drilling on three sections along strike. The drilling intersected relatively narrow and moderately west-dipping zones of weathered tungsten-rich breccia (See Figure 12).

Forward Planning
The new results 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. Further drilling is planned at several prospects.
The Company looks forward to keeping Shareholders and the market updated on the drilling progress and results obtained from the ongoing drilling program at Khao Soon.
