Drilling Extends Gold Mineralisation at Van Uden by a
Further 1.8km to 4.3km in Total
Early Signs from Laterite Drilling Indicate Potential Additional
Mineralisation to Support Near Term Heap Leach Opportunity
Highlights
TG Metals Limited (TG Metals or the Company) (ASX:TG6) is pleased to provide results from
drilling at the Van Uden Gold Project (Van Uden or the Project).
These results, from five reverse circulation (RC) reconnaissance holes drilled along strike of
the Van Uden gold deposit (Figure 1), were designed to test the potential for resource
extensions in large step out holes. Pleasingly, the holes intersected gold mineralisation and
prove the fertile Van Uden shear continues along a strike of at least a further 1.8km for a total
of at least 4.3km. Result highlights include:
• TGGR052 - 6m @ 5.57 g/t Au from 84.0m including 3m @ 10.69 g/t Au from 84.0m
• TGGR148 - 6m @ 0.72 g/t Au from 27.0m
• TGGR149 - 5m @ 0.79 g/t Au from 30.0m
■ Recent reconnaissance drilling has extended the strike of known gold
mineralisation at the Van Uden Project by a further 1.8km south of the
existing MRE1
■ Results support potential material future resource extension to the south
■ Drilling identified shallow gold mineralisation – including 6m @ 5.57 g/t Au
■ Diamond drilling testing the depth extensions of the Van Uden resource
have been submitted for analysis
■ Laterite drilling targeting extensions of the current resource is underway
with initial results confirming the presence of favourable pisolitic laterite
from surface
■ The current laterite resource of 17,700 ounces1 supports the near term
cashflow opportunity from the heap leach operation at Van Uden, driven by
>90% heap leach recoveries
■ Growth in the laterite resource will have a positive economic impact on the
proposed Laterite Heap Leach Operation
■ Heap Leach study results expected by end of June

TG Metals CEO, Mr. David Selfe stated;
“Final assay results from RC drilling at Van Uden continue to show strong high grade gold
mineralisation within the current MRE and we have now also proven a continuous strike length
of 4.3km, extending south of the historic Tasman pit and demonstrate the resource growth
potential of the Van Uden shear.
We are also excited that there are early positive indications from the auger drilling to extend
the laterite gold resource, with pisolitic laterite sighted from surface. This is an important
outcome as we progress the Heap Leach opportunity for the Company. The Heap Leach is
expected to provide material revenue opportunity for the Company as we continue to progress
the larger production opportunity at Van Uden.”

Van Uden Drilling
The purpose of this reported drilling was to expand on the current Van Uden mineral resource
estimate (MRE) via infill and test positions along strike for extensions to the Van Uden
mineralisation to the south. The drilling successfully intercepted the gold mineralisation on a
flat fault structure at the contact between the metasediments and the basalt. This is the same
structure identified as a core part of the Van Uden Gold Deposit and MRE. The Van Uden
shear is interpreted to become much steeper to the east and this will require further drill
testing. This drilling confirms the extension of the Van Uden mineralisation to 1800m south of
the current MRE. Figure 1 shows the drilling locations, with a cross section insert.
The Van Uden shear mineralisation was intersected in drillhole TGGR147, at the southern
most tenement boundary. The shear position is not well defined in this area as sand dune
cover is extensive, obliterating surface geochemistry. This result indicates the location of the
mineralised shear, with follow-up exploration drilling being planned.
Drillhole TGGR052 is located near the historic Tasman open pit and was drilled to test
continuity of high-grade gold mineralisation. The drillhole successfully intercepted 6m @ 5.57
g/t Au from 84m downhole, including 3m @ 10.69 g/t Au at the top of the intercept. This
intercept is not currently included in the Van Uden MRE.
The full significant assay results above 0.3g/t Au are provided in Table 2.
Four diamond drill core holes within the main Van Uden resource area have assays pending.
The purpose of this drilling was to capture geotechnical information for inclusion into mine
designs and to provide core sample of fresh gold bearing material. The geotechnical logging
has been completed and the core cut for assaying. Assays are expected in July for this drilling.
Laterite Drilling Progress
As reported in ASX announcement dated 28 May 2026, a program of auger drilling testing
extensions to mineralised surface laterite outside of the current Van Uden MRE, is ongoing
and progressing well. The aim of this program is to identify new and additional laterite hosted
gold gold mineralisation for follow up resource drilling. Within the current Van Uden global
resource, 1,053,000 tonnes of mineralised laterite is identified, at a grade of 0.52 g/t Au,
totaling 17,700 ounces (see Table 3 for full MRE). This material is amenable to Heap Leach
processing on site, with detailed metallurgical testwork of these processes well advanced
(ASX announcement 14 May 2026). First samples from the program, with logging confirming
the presence of pisolitic laterite, have been sent to the analytical laboratory and results are
expected in July.

Drilling Program Details
The RC drilling for this report was conducted with two drill rigs, both truck mounted. A
Schramm X300 and a Schramm T660 drill rig. The smaller Schramm X300 rig completed the
shallow drilling, less than 90m depth in the oxidised to semi-oxidised regolith and the deeper
holes were completed with the larger Schramm T660 rig. A total of 5 drillholes with assays
returned, are included in this report for 558m of RC drilling. The reported RC drillhole dips are
all -60o
and at an azimuth of 250o
to align with the previous historical grid. Also included are
the diamond drill core tails and holes drilled for geotechnical logging. These holes have
variable azimuths and dips, all diamond drillholes were downhole surveyed. See Table 1 for
drill collar information.
The reported drilling has one drillhole within the current MRE and four others are deemed
exploration holes to the south of the current MRE. The drill collars of drillholes have collar
coordinates from DGPS field surveying using the MGA2020 Zone 50 grid and datum to align
with DMPE requirements for government data submission. See Figure 1 for drill collar
locations.
The reported assays are from individual 1m samples in the known mineralised shear zone 4m
composites taken outside of these zones. Both sample interval batches were assayed using
the Photon assay technique. As experienced previously, some drillholes recorded multiple
gold mineralised intercepts downhole, refer to Table 2.
Follow-up Work
The current auger laterite drilling program will be followed up with a resource drill-out.
Diamond drill core drilling assays expected in July.
Approvals being sort for RC Drilling along strike north and south of the Van Uden MRE.
Workstreams for the laterite heap leach study are continuing.

Van Uden Gold Project Description
The Project is located on the Forrestania Greenstone Belt, Figure 2, 90km east-northeast of
Hyden and 120km south of Southern Cross. It is 90km to the Marvel Loch (producing), 140km
to Edna May (care & maintenance) gold processing Plants and 75km to Cosmic Boy and
100km to Lake Johnston processing plants under conversion to gold. The Project lies 12.5km
to the south west of the Mt Holland lithium mine and is 130km north west from the Company’s
established Burmeister lithium deposit at the Lake Johnston Project.
The Van Uden gold MRE has 56% in the Indicated category allowing progression to mining
and processing studies in the near term. The surface Laterite is the current focus for heap
leach technology. The updated MRE below in Table 3 shows the current resource status:
Table 3: MRE – Van Uden Gold Deposit
NOTES: The Mineral Resources statement conforms to the Australasian Code for Reporting of Exploration
Results, Mineral Resources and Ore Reserves (JORC Code) 2012 Edition. All tonnages are dry metric tonnes.
The laterite portion of the mineralisation has been reported at a cut-off grade of 0.10 g/t Au by area within a
A$6,000/oz Au optimised pit shell. All other material types are reported at a cut-off grade of 0.30 g/t Au by area
within a A$6,000/oz Au optimised pit shell based on mining parameters and operating costs typical for Australian
open pit extraction deposits of a similar scale and geology.
Minor discrepancies may occur due to rounding of appropriate significant figures. The resources comply with the
Reasonable Prospects for Eventual Economic Extraction (RPEEE), a key principle in mineral resource reporting
that requires the competent person to demonstrate that a mineral deposit has the potential to be economically
extracted in the future.

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.
• All holes were sampled at 1 m intervals using an on-board Ox
Cyclone Sampling system with fixed cone splitter engineered for
the rig. Samples outside of the known gold mineralised zones are
composited to 4m samples and assayed prior to the 1m intervals
being submitted for assay. 4m composite samples are not reported.
• Two samples (Original + Duplicate) were collected each metre,
representing 12.5 % of total cyclone discharge per split.
• Certified reference materials (CRMs) were inserted every 20
samples, and coarse blanks every 40 samples. All samples were
dry.
• Samples were transported to Laboratory: SGS Australia Pty Ltd,
Kalgoorlie WA (17 Stockyard Way) for PhotonAssay™ PAAU02,
two-cycle analysis on 500g of crushed material.
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).
• Reverse-circulation (RC) drilling was completed using two rigs for
these reported results, selected to match depth requirements and
operational efficiency
• Impact Drilling – RIG 02
o Rig: Schramm T660 (8×8 MAN carrier)
o Year: 2006 (rebuilt 2021)
o Capability: High-capacity deep RC drilling
o Depth capacity: >500 m (4.5″ RC)

mounted controls, onboard dust collection and suppression.
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.
• Sample recovery was visually assessed and recorded by comparing
the two splitter outputs each metre.
• All samples were dry with negligible loss.
• Given the dry conditions and fixed splitter configuration, no material
bias is expected.
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.
• RC drill cuttings of the metre intervals were sieved, washed and
placed into a chip tray for geological logging and for future
reference. Clay intervals in regolith were not sieved, however any
remnant rock/hard material were sieved and washed for
identification.
• TG Metals Limited geological logging system:
o Recognises fresh rock vs regolith.
o Is both qualitative and quantitative.
o Industry and geological standards were followed recording
every detail observed.
o Every interval (m) drilled was logged.
o 20m interval Chip trays were labelled and used to store a
small representative sample for future reference.
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.
• Samples were split at the rig using a fixed cone splitter, producing
two by 12.5 % sub-samples per metre.

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.
• Mineralisation is interpreted as shear- and vein-hosted along local
contacts; drilling orientations are appropriate for testing mineralised
zones and introduce no material bias at this scale.

Sample
security
• The measures taken to ensure sample security. • Samples were bagged and sealed in calico bags inside polyweave
sacks, cable-tied and labelled at the rig.
• Chain of custody was maintained by TG Metals personnel, who
personally transported samples directly from site to SGS Kalgoorlie
Laboratory for registration and analysis.
Audits or
reviews
• The results of any audits or reviews of sampling techniques and data. • No external audits specific to this program.
• Internal QAQC checks identified no material issues.

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.
• All drilling is within in Mining Leases 77/477, M77/478 and
M77/523. The tenements are currently held by TG Gold Pty Ltd
(80%) and Barto Gold Mining Pty Ltd (20%). Ownership: TG Gold
Pty Ltd is a 100% subsidiary of TG Metals Limited (ASX: TG6).
• The tenements are in good standing and unaffected by heritage or
environmental encumbrances.
Exploration
done by other
parties
• Acknowledgment and appraisal of exploration by other parties. • Dieman, Laterite and Tasman Pits were previously mined and
drilled by earlier operators as part of historic gold extraction.
• Historic data have been reviewed where available.
Geology • Deposit type, geological setting and style of mineralisation. • Orogenic, shear- and vein-hosted gold mineralisation occurs within
the Forrestania greenstone belt along the sediment–mafic contact,
which is mapped as the Van Uden Shear.
Host rocks are amphibolite-facies metasediments and mafic
volcanic units showing local quartz veining and minor schistose
alteration. Gold mineralisation is structurally controlled and
consistent with regional orogenic systems of the Western
Australian Yilgarn Craton.

Criteria JORC Code explanation Commentary
• Most gold mineralisation is formed withing the sediments, however
where the mafic/sediment contact undulates, the gold
mineralisation is known to occur within the mafic rocks.
