SOIL ASSAY RESULTS EXTEND GOLD TARGETS TO
OVER 6 KM AT VAN UDEN
Highlights
■ Highly anomalous gold in soil results have more than doubled the strike
of gold mineralisation at the Van Uden Gold Project to 6.5 kilometres
■ Results define targets to materially extend existing resources along
strike
■ Analysis confirms new soil anomalies have been poorly tested by
shallow historical drilling
■ Preparations for drilling at Van Uden complete
TG Metals Limited (TG Metals or the Company) (ASX:TG6) is pleased to provide new gold
assay results from historical soils sampling at the Van Uden Gold Project (Van Uden).
The results confirm highly anomalous gold in soils on-trend to the north and south of the
existing Van Uden mineral resource, within the project’s granted mining leases. Additional
anomalies have been generated on the footwall and hanging wall of this mineralised trend,
identified as the Van Uden Shear Zone. The assay results have increased the mineralised
strike at Van Uden to approximately 6.5 kilometres, with the current MRE occupying a strike
of 2.5 kilometres.
Historical drilling shows the gold soil anomalies have been poorly tested. Much of the historical
drilling1 to the north and south of the Van Uden deposit is shallow RAB (rotary air blast) drilling.
Previous isolated gold intercepts in RC (reverse circulation) drilling were not followed up and
presents a compelling opportunity for the Company to expand the defined gold mineralisation
of the Van Uden deposit.
Figure 1 shows the Van Uden deposit and the soil sampling coverage, with the new anomalies
and historical drill holes displaying maximum gold values assayed.
TG Metals CEO, Mr. David Selfe stated;
“Van Uden is shaping up as a very large gold system. The potential to expand the existing
gold resource along strike and down dip is enormous. With over 6 kilometres of strike now
defined, we look forward to adding to this already substantial resource, which covers only 2.5
kilometres of strike, drilled to a relatively shallow depth averaging about 80 metres to the north
and 120 metres in the south. This new data has given us another key strategic target to be
incorporated into our drilling plans, which kicks off this month and will continue through the
remainder of 2025.”

Soil Sampling and Historical Drilling
Soil sampling was conducted over the entire Mining Leases area as shown in Figure 1. This
broad spaced grid of 200m x 200m soils was collected by Kidman Resources in 2019 and
originally analysed for Lithium and associated elements. No gold assays were performed at
that time. The pattern was selected to give whole of tenement coverage for Lithium
exploration, see Figure 2. A closer spaced 200m x 100m pattern was infilled closer to the Van
Uden shear. Recently, TG Metals assayed the soil pulps with 50g fire assay for gold and the
results show that the Van Uden Shear has a lot more potential outside the known defined
resource. Significant results above 10ppb Au are listed in Table A.
The closer spaced soil samples assayed for gold clearly define the Van Uden shear and
correlate well with the known Van Uden deposit gold mineralisation. This is sufficient for drill
planning to test these anomalies, both north and south of the Van Uden gold deposit, for
continuation of the Van Uden gold mineralisation.
Whilst the gold in soil anomaly dissipates to the south, it is believed that this area of the tenure
is influenced by transported soils which would impede the effectiveness of soil sampling for
gold in this area. Even so, this represents 6.5 kilometres of continuous strike gold in soil
anomaly from the northern tip of the granted Mining Leases towards the south. It is a
substantial drilling target considering only 2.5 kilometres has been effectively tested with RC
drilling that has defined the Van Uden resource.
Historical drilling for gold was concentrated along the Van Uden gold deposit, Indicated and
Inferred Mineral Resource of 6.35Mt at 1.1g/t Au for 227,140 oz gold (ASX release 5 June
2025, refer to Table B), with shallow and wide spaced drilling to the north and south which
hasn’t effectively tested the remainder of the Van Uden shear. Figure 1 includes the historical
drillhole collars with maximum assays gold value. These drillholes were re-stated in the
acquisition announcement (ASX: 6 March 2025). Most of the drilling showing no gold values
was shallow RAB drilling which failed to reach target depth and was too wide spaced to test
the mineralised Van Uden Shear.
Gold Anomalies
The main gold in soil anomaly of significance is located on the Van Uden Shear. The shear is
on the contact between mafics on the west and meta-sediments on the east. The shear
variably dips to the east, trending steeper in the south and flatter in the north. The area has
been well mapped in the past, with the newly defined gold in soil anomalies following the Van
Uden Shear and defining the western margin. Sampling was conducted over the known Van
Uden gold deposit, and the tenor of these assays correlate highly with the soil assays to the
north and south, indicating that the potential gold mineralisation is similar to the known Van
Uden deposit. These gold anomalies are high tenor along the 6.5km length of the shear tested.
To the west of the Van Uden Shear, gold anomalies around circular magnetic features are
also apparent. Further investigation is required to determine if these anomalous features are
indicative of below surface gold mineralisation. They are of significance as there is peak gold
in soil assay clusters above 30 ppb Au.

Follow-up Work
Programmes of Work (POWs) have been lodged for drilling on the Van Uden deposit
extensions as well as for the Gold City prospect. Infill soil sampling at Gold City has also been
planned.
Drilling preparations for within the Tasman pit are complete with surveying of the drill collar
locations occurring in the past few days. The drilling contract has been awarded and drilling
will commence upon mobilisation of a suitable drill rig, estimated to be around 17th September.
Van Uden Gold Project Description
The Project is located on the Forrestania Greenstone Belt, Figure 3, 90km east-northeast of
Hyden and 120km south of Southern Cross. It is close to the Marvel Loch (producing) and
Westonia - Edna May (care & maintenance) gold processing Plants and is 130km from the
Company’s established Burmeister lithium deposit at the Lake Johnston Project.
Van Uden Gold consists of an Indicated and Inferred Mineral Resource as per Table B below
on four granted mining leases, four granted exploration licences, one exploration licence
application and two miscellaneous licences (for haul roads). The Project lies to the west of the
Mt Holland lithium mine, south of the operating Marvel Loch gold Plant, and southeast of the
Edna May gold Plant.

Table B: MRE – Van Uden Gold Deposit
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. It has been reported
at a cut-off grade of 0.35 g/t Au by area within a A$5,000/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 qualified person to demonstrate that a mineral deposit has the
potential to be economically extracted in the future.
By applying the appropriate RPEEE the JORC 2012-compliant MRE will facilitate a smooth transition to the
anticipated update to the JORC Code expected by the end of 2025.

Section 1 Sampling Techniques and Data
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.
Soil samples were collected by spade (at approx. 20cm) and sieved in the
field to pass 2mm sieve to obtain up to 1kg of sample. The sample was
placed in a pre-numbered calico bag and dispatched to Australian
Laboratory Services Pty Ltd (ALS) located in Perth WA, for low detection
level gold analysis by fire assay.
•
Include reference to measures taken to ensure sample representivity
and the appropriate calibration of any measurement tools or systems
used.
Soil sampling was conducted on a 200m x 200m over all 4 Mine leases
and tightened to 200m x 100m over the Van Uden Shear. The patter was
oriented E-W. TG Metals Limited inserted gold standard and sample
duplicate every 50 samples. ALS standards and laboratory replicates were
reported and used by TG Metals Limited for QA/QC reporting.
•
Aspects of the determination of mineralisation that are Material to the
Public Report.
No mineralisation was observed in the soil samples results and
determination of anomalism was based on ALS assay results. All samples
for assay were submitted to aa Certified Laboratory – Australian
Laboratory Services Pty Ltd.
•
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 samples dispatched to ALS for Au by fire assay and Inductively Coupled
Plasma Atomic Emission Spectrometry (ICP-AES) were homogenised and
pulverized. 50g of sample was mixed with flux composed of PbO and
SiO2 and variable amounts of borax, soda ash and other reagents. The
flux and sample mix were then heated at high temperature (>1,000°C) to
decompose rock lattices and allow gold within the sample to be collected
into a lead button. The button was placed in a porous cupel and heated
again in an oxidising environment to convert lead to lead oxide that is
absorbed into the cupel, leaving the precious metals behind as a doré bead
or prill. The gold content of the prill is then determined/measured by ICPAES analytical technique.

Industry gold standards were inserted by ALS. Laboratory replicates were
measured and reported. TG Metals sample duplicates and gold standard
were inserted at the 50th sample interval
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.
The sieved field sample of +1kg was appropriate for the grain size of the
surface material.
•
The nature, quality and appropriateness of the assaying and laboratory
procedures used and whether the technique is considered partial or
total.
All samples dispatched to ALS were analysed for gold by fire assay using
ICP-AES. Samples were homogenised and pulverised from which 50g of
sample was mixed with flux composed of PbO and SiO2 with variable
amounts of borax, soda ash and other reagents. The flux and sample were
mixed, then heated at high temperature (>1,000°C) to decompose rock
lattices and allow gold within the sample to be collected into a lead button.
The button was placed in a porous cupel and heated again in an oxidising
environment to convert lead to lead oxide that is absorbed into the cupel,
leaving the precious metals behind as a doré bead or prill. The gold
content of the prill is then determined by ICP-AES. This analytical method
was chosen to detect low level gold as advised by ALS.
