Background

Australian tungsten developer, Tungsten Mining NL (ASX: TGN) (“TGN” or “the Company”) is pleased to report on the results from drilling at the Hatches Creek Project. Between the 31 August to 6 October 2024, the Company completed 65 reverse circulation drill holes totalling 6,803 metres, testing five targets at the Hatches Creek Project (Figure 1).

The objective of the drilling was to test extensions to and confirm continuity of tungsten mineralisation identified by previous reverse circulation (RC) drilling programs completed by the GWR Group Limited (ASX: GWR) (GWR) in 2016 to 2019.[1]

The recent drilling tested five targets and intersected significant tungsten mineralisation at all five targets. Drilling at Hit or Miss, Treasure and Green Diamond also intersected broad zones of highly anomalous copper mineralisation.

Refer to GWR ASX announcements between 2016 and 2019 for GWR’s drilling results.[1]

Hit or Miss

In 2016 to 2019, GWR conducted drilling which intersected significant tungsten-copper mineralisation associated with multiple mineralised structures over a width of 250 metres and strike length of 240 metres. Mineralisation was open to the north and south. Historic workings extend 160 metres north and 130 metres south of GWRs drill holes.

Mineralisation at Hit or Miss is associated with a series of parallel north to northwest striking quartz lodes that dip steeply towards the west. Quartz lodes are hosted by dominantly felsic volcanic rocks and are accompanied by widespread copper mineralisation.

In the September 2024 quarter, the Company drilled 35 RC holes for 3,487 metres to test strike extensions to known mineralisation at Hit or Miss (Figure 2). Drilling intersected significant tungsten mineralisation on the southern (Figure 3), northern and eastern (Figure 4) strike extensions. Better intersections included the following:

  • 7 metres at 0.38% WO3 from 25 metres in HCRC067, 5 metres at 0.44% WO3 from 12 metre in HCRC079 and 6 metres at 0.32% WO3 from 76 metres in HCRC076 associated with the southern strike extension,

  • 17 metres at 0.43% WO3 from 1 metre in HCRC078 and 5 metres at 0.94% WO3 from 34 metres in HCRC077 associated with the eastern strike extension,

  • 14 metres at 0.12% WO3 from 28 metres in HCRC092 and 20 metres at 0.09% WO3 from 2 metres and 6 metres at 0.11% WO3 from 25 metres in HCRC097 associated with the northern strike extension

Treasure

In 2016 and 2017, GWR drilled 12 RC holes at Treasure intersecting significant tungsten mineralisation over 350 metres of strike. Mineralisation in the southern half of the prospect is associated with multiple north striking quartz lodes within a 30 to 50 metre wide zone. Tungsten mineralisation in the southern zone is also accompanied by low grade copper mineralisation. Tungsten mineralisation in the northern half of the prospect is associated with a single high-grade zone dipping steeply towards the west. Mineralisation is hosted by felsic volcanic units.

In the September 2024 quarter the Company drilled 12 RC holes for 1,242 metres to confirm continuity of tungsten mineralisation present at Treasure (Figure 5). Drilling intersected significant tungsten mineralisation at target depths (Figure 6) and confirmed continuity of mineralised structures over 350 metres of strike. Intersections included the following:

  • 5 metres at 2.05 % WO3 from 71 metres in HCRC085,

  • 7 metres at 1.39% WO3 from 88 metres in HCRC086,

  • 15 metres at 0.44% WO3 from 103 metres in HCRC110,

  • 9 metres at 0.67% WO3 from 131 metres in HCRC083

Green Diamond

In 2017, GWR drilled one RC hole at Green Diamond intersecting multiple zones of tungsten mineralisation in a 100 metre-wide corridor. Better intersections included 4 metres at 0.42% WO3 from 0 metre, 4 metres at 0.37% WO3 from 59 metres and 6 metres at 0.90% WO3 from 90 metres. Mineralisation is associated with multiple east-west striking quartz lodes hosted by fine grained sediments that dip steeply towards the south (60 – 70°) and are targeted by historic working over a strike length of 450 metres.

In September/October 2024, the Company drilled 7 RC holes (HCRC115 – HCRC119, HCRC151 – HCRC152) for 834 metres to test strike extension at Green Diamond (Figure 7). Drilling intersected significant mineralisation over 300 metres of strike that is open to the west, east and down dip . Three styles of mineralisation are present:

The first style of mineralisation is narrow high-grade zones hosted by fine grained sediments dipping steeply towards the south (Figure 9). Intersections from this style of mineralisation included the following:

  • 4 metres at 1.45 % WO3 and 0.16% Cu from 54 metres in HCRC152,

  • 4 metres at 1.13% WO3 and 0.02% Cu from 80 metres in HCRC116,

  • 2 metres at 1.84% WO3 and 0.62% Cu from 44 metres in HCRC115,

  • 4 metres at 0.54% WO3 and 0.01% Cu from 93 metres in HCRC151.

The second style is broad zones of low to medium grade tungsten-copper mineralisation associated with the Pedlar Gabbro/sediment contact with a shallower (25 - 40°) southerly dip (Figure 8). Intersections from this style of mineralisation included the following:

  • 37 metres at 0.14 % WO3 and 0.30% Cu from 0 metre including 19 metres at 0.20% WO3 and 0.34% Cu from 15 metre in HCRC116,

  • 26 metres at 0.12% WO3 and 0.21% Cu from 0 metre in HCRC151,

  • 19 metres at 0.11% WO3 and 0.40% Cu from 0 metre in HCRC152,

  • 20 metres at 0.10% WO3 and 0.31% Cu from 0 metre in HCRC117.

The third style is a single intersection of high-grade copper mineralisation associated fine grained sediment that assayed 5 metres at 3.86% Cu from 68 metres including 3 metres at 6.30% Cu (>1.0% Cu) from 68 metres in HCRC116. The geometry of this zone is unknown.

Better tungsten intersections are listed in Table 3. For a complete list of intersections refer to Appendix 1.

Black Diamond

In 2017, GWR drilled three RC hole at Black Diamond to test the Main Lode, Number 3 Lode and South Lode hosted by fine grained sediments. Drilling intersected significant tungsten mineralisation at target depths including 11 metres at 0.44% WO3 from 29 metre, 16 metres at 0.18% WO3 from 5 metre, and 2 metres at 0.95% WO3 from 60 metre. Mineralisation is associated with multiple east-northeast striking quartz lodes that dip steeply towards the south (60 – 80°) and are targeted by historic working over a strike length of 250 metres.

In October 2024 the Company drilled 5 RC holes (HCRC154 – HCRC158) for 580 metres to test strike extension at Black Diamond (Figure 7). Drilling intersected fine-grained sediments and two 10 - 20 metre thick mafic intrusive units that dip shallowly towards the south. Stronger tungsten mineralisation was intersected in sediments adjacent to or within the mafic units (Figure 9) over a strike length of 200 metres. Mineralisation remains open to the west, east and down dip . Better intersections included the following:

  • 14 metres at 0.14% WO3 from 0 metre in HCRC154,

  • 3 metres at 0.81% WO3 from 104 metres in HCRC155,

  • 6 metres at 0.36% WO3 from 23 metres in HCRC157,

  • 4 metres at 0.59% WO3 from 50 metres in HCRC158.

Bonanza

In 2017, GWR drilled one RC hole at Bonanza to test the Main Lode that is associated with east-northeast strike quartz veins hosted by fine grained sediments. Drilling intersected significant tungsten mineralisation at target depths including 6 metres at 0.42 % WO3 from 32 metres and 6 metres at 0.49 % WO3 from 41 metres associated with the Main Lode. A second parallel structure was intersected assaying 5 metres at 0.10 % WO3 from 6 metres. GWR drilling did not test multiple parallel structures south of the Main Lode defined by historic working that targeted quartz lodes dipping steeply towards the south (60 – 80°). Historic workings are present over 230 metres of strike.

In September/October 2024, the Company drilled 6 RC holes (HCRC087 – HCRC090, HCRC150, HCRC153) for 660 metres to test strike extensions at Bonanza (Figure 7). Drilling intersected multiple mineralised structures over 160 metres of strike that dip steeply towards the south (Figure 10) and are open to the west, east and down dip . Better intersections included the following:

  • 5 metres at 1.51% WO3 from 109 metres in HCRC089,

  • 8 metres at 0.82% WO3 from 32 metre in HCRC087,

  • 6 metres at 0.81% WO3 from 19 metres in HCRC088,

  • 6 metres at 0.60% WO3 from 49 metre in HCRC088.

Soil Geochemistry

In June 2024, the Company collected 171 soil samples across the Green Diamond, Black Diamond and Bonanza workings that are present on Wolfram Hill. Sampling defined a number of strong coincident tungsten-copper-molybdenum-bismuth soil anomalies demonstrating excellent potential to define new mineralised zones (Figure 11). Targets are as follows:

  • 650-metre long soil anomalies associated with the Pedlar Gabro/Sediment contact where drilling at Green Diamond intersected up to 37 metres at 0.14 % WO3 and 0.30% Cu from 0 metre in HCRC116. This mineralisation was not targeted by historic workings and is open to the west, east and down dip.

  • 700-metre long strong soil anomalies associated with the Bonanza-Black Diamond trend. Mineralisation in drilling at Bonanza/Black Diamond is open to the west, east and down dip.

  • A third 300-metre-long strong soil anomalies between Green Diamond and Black Diamond.

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 2 - 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.
The latest drilling campaign completed by Tungsten Mining NL
(“TGN”) was sampled using Reverse Circulation (RC) drilling
conducted from 31 August to 6 October 2024.
A total of 65 RC drillholes (6803m) were drilled in the latest
campaign and the majority of the holes were drilled at
approximately 35⁰ - 60⁰ to stratigraphy and mineralisation.
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 Leica GS18 RTK survey equipment with
specifications of +/- 20mm N,E and Z. .
Downhole surveying was measured by the drill contractors.
DDH1 used a Axis North Seeking Multi-Shot gyroscopic system
in the drill rods. Accuracy is ±0.75° for azimuth and ±0.15° for
inclination.
Remote Drilling Services used a DeviGyro RG40 gyroscopic
system in the drill rods. Accuracy is ±0.5° for azimuth and ±0.1°
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 mineralisation. 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
The RC drilling crew collected 1 metre intervals from the
cyclone and the sample was split using a cone splitter to
produce two representative 2 – 4 kilogram samples in calico
bags.
The cone splitter was cleaned by hosing with pressurised air to
eliminate sample contamination. One of the calico samples is
for analysis and the second duplicate sample is retained as a
reference sample for possible reanalysing / QAQC activities.
The bulk reject material was collected at 1 m intervals from the
cyclone and placed on the ground for geological logging.
Samples from the current drilling programme were submitted
to Nagrom the Mineral Processors, Kelmscott, WA, for a
standard XRF Tungsten Suite.
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 65 RC drillholes with depths ranging from 6 to
185 m, averaging 105 m. RC drilling used a face-sampling
hammer that produced a nominal 140 mm diameter hole.
TGN RC holes were surveyed in-rods at 30 m intervals by the
drill contractors. DDH1 used a Axis North Seeking Multi-Shot
gyroscopic system. Remote Drilling Services used a DeviGyro
RG40 gyroscopic system in the drill rods
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 were 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 of 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.
Criteria JORC Code explanation
Commentary
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. The washed chip trays are stored in sea containers on
site.
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.
No drill core collected during the current drill program.
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 2 - 4 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 Nagrom the Mineral Processors, Kelmscott, WA and dried,
split if over 2.5 kg and pulverised to 80% passing 75µm.
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 and
standards were inserted at intervals of one in 25 and blanks at
intervals of one in 50. Geological logging was used to ensure
duplicate 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 cone
split samples at the rig. Repeatability in RC duplicate samples
was found to be excellent with an R2of 0.97 for tungsten and
0.98 for copper.
Whether sample sizes are appropriate to the grain size
of the material being sampled.
Assays from duplicate samples repeated well with no
systematic bias for tungsten and copper.
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, and copper mineralisation present at Hatches Creek.
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.
TGN 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.
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 13 holes at Hit or Miss.
Data is stored in the database.
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 commercial standards, blanks 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 standards, blanks and duplicates for RC
drilling against the drill database.
Criteria JORC Code explanation
Commentary
The use of twinned holes.
TGN re-drilled and were within 5 metres of three failed RC
holes. Twin holes intersected similar widths and grades for
mineralisation. Individual high-grade intervals 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.
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.
TGN drillhole collar locations were picked up by a licenced
surveyor using a Leica GS18 RTK survey equipment with
specifications of +/- 20mm N,E and Z. ..
Downhole surveying was measured by the drill contractors.
DDH1 used a Axis North Seeking Multi-Shot gyroscopic system
in the drill rods.
Remote Drilling Services used a DeviGyro RG40 gyroscopic
system.
Specification of the grid system used.
Geocentric Datum of Australia 1994 (GDA94) - Zone 53.
Quality and adequacy of topographic control.
High resolution aerial photography and digital elevation survey
was flown by Ausurv Surveyors Pty Ltd in 2015 with expected
height accuracy of +/- 0.2 m.
Data spacing and
distribution
Data spacing for reporting of Exploration Results.
Drill spacing varies from a 40 to 80 metre section spacing with
a 40 metre hole spacing.
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 present is considered sufficient to
determine target size.
Whether sample compositing has been applied.
Only 1 metre drill samples were collected, and no sample
compositing was undertaken.
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 as close as possible to perpendicular to the
strike of the dominant vein geometry and mineralised
stratigraphy. Given the steep nature to quartz lodes (dips of
50⁰ to 90⁰), drilling intersected mineralised structures at 40⁰ -
75⁰.
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 data collected during geological mapping has
confirmed that drill orientation did not introduce any bias
regarding the dominant orientation of mineralised veining. A
second relatively minor east-west strike vein set sub-paralleled
drill azimuths at Hit of Miss.
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.

Geology

Tungsten mineralisation at Hatches Creek is associated with quartz veins in shear zones within a variety of Proterozoic host rocks forming part of the Davenport Province.

Hit or Miss

The Hit or Miss deposit lies in a sequence of interbedded siltstones, sandstones, quartzite and felsic volcanic rocks striking at about 070° and dipping at 55–60° to the south.

Most of the mineralised structures lie in the porphyritic felsic volcanics which overlie the sedimentary sequence. Quartz reefs form three dominant trends as follows:

  • On the western side of Hit or Miss quartz reefs dip at 75–80° toward the west (280°)

  • On the eastern side of Hit or Miss quartz reefs dip at 65–75° toward the west northwest (300– 310°)

  • Crosscutting the Hit or Miss deposit are several roughly east-west striking quartz reefs that dip steeply (85°) towards the north (350°).

Treasure

At Treasure, tungsten mineralisation forms continuous lodes which can be traced from the north to south of the prospect. The lodes occupy shears hosted by felsic to intermediate volcanic rocks and strike within 20° of north and dip steeply towards the west.

The high-grade northern (Treasure) and southern (Hidden Treasure) sections of Treasure are separated by relatively weak mineralisation associated with a quartzite unit (20 – 30 metre thick) in the central portion of the prospect. Wolframite is the dominate tungsten mineral, with no scheelite recognised, and only traces of copper, bismuth, and lead.

Green Diamond

Green Diamond
Deposit type, geological setting and style of The Green Diamond group consists of an almost continuous line
mineralisation. of historic workings extending over 450 metres. Mineralisation
is hosted by massive well-sorted quartz sandstone which dips
steeply towards the south. Mineralisation is parallel to the
bedding with individual lodes commonly bifurcating and
variable geometry.
The Green Diamond Main Lode is more heavily mineralised
than the adjoining lodes. The Main Lode consists of a series of
quartz veins and splays within a 1 -2 metre shear that dip at 45-
60° towards the south. Wolfram is the dominant tungsten
mineral accompanied by varying amounts of scheelite and
copper.
Concentrates from Green Diamond assayed as high as 7.63% Bi
and 2.03% Cu derived chiefly from azurite, malachite, and
bismutite. Bismuthinite, cuprite, and native copper have also
been identified in the oxidized zone. Bornite, chalcocite,
covellite pyrite, bismuthinite, and chalcopyrite are present
when fresh.
TGN drilling in 2024 intersected narrow high-grade zones
associated with mineralisation target by historic working.
Drilling also intersected a second style of mineralisation
associated with the Pedlar Gabbro/sediment contact. This
style consisted of broad zones of low to medium grade
tungsten-copper mineralisation hosted by weathered mafics
and sediments that dip shallowly (25 - 40°) towards the south.

Black Diamond

The Black Diamond group consists of three lodes and several parallel quartz reefs that outcrop over about 250 metres. The Main Lode is the most important producing the most wolframite. The lodes are hosted by sandstone, quartzite, greywacke, and siltstone, strike at about 060° and dip to the south at 60-80°. Tungsten is associated with dominantly wolframite and minor amounts of scheelite, bismutite, and malachite. Drilling intersected fine-grained sediments and two 10 - 20 metre thick mafic intrusive units that dip shallowly towards the

south. Stronger tungsten mineralisation was intersected in sediments adjacent to or within the mafic units over a strike length of 200 metres.

Bonanza

The Bonanza Group is situated about 100 metres south-west of the Black Diamond Mine and about 50 – 100 metres north of the western end of the Green Diamond Group.

The group extends over 230 metres in a north-north-easterly direction and consists of a number of lodes striking at about 060°, of which the Bonanza Lode is the most important. Mineralisation is hosted by quartz sandstone and greywacke and is dominantly wolframite with minor scheelite, copper and bismuth minerals.

maximum
and/or
minimum
grade
truncations (e.g. cutting of high grades) and cut-off
grades are usually Material and should be stated.
All intersections greater than 2m at 0.05% WO3using a lower
cut-off grade 0.05% WO3, no top cut grade and up to 2m of
internal waste are reported in Appendix 1.
High-grade intervals of better than 1m at 0.50% WO3are also
reported in Appendix 1.
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’).

Hit or Miss - holes will intersect mineralisation at
between 35° - 55° and true thickness will be
between 65 to 75% of the intersection thickness.

Treasure - holes will intersect mineralisation at 25°
to 50° and true thickness will be approximately 60%
to 70% of the intersection thickness.

Green Diamond - holes will intersect tungsten
mineralisation at 60⁰ - 90⁰ and true thickness will be
approximately 70% to 100% of the intersection
thickness.

Black Diamond - holes will intersect tungsten
mineralisation at 40⁰ - 65⁰ and true thickness will be
approximately 60% to 80% of the intersection
thickness.
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.
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 Intersections greater than 2m at 0.05 WO3for the current
drill program are reported and holes with no significant
mineralisation are documented in Appendix 1.

Criteria JORC Code explanation Commentary Other substantive Metallurgical studies to date have demonstrated the exploration data amenability of ore from Hatches Creek to gravity separation and magnetic separation, effective at concentrating the material to 50% WO3.

Gravity testwork has predominantly comprised table testwork, at a series of size fractions and jigging testwork, to assess and evaluate coarse concentration of this material.

Testwork has largely been positive, with further work underway to establish liberation thresholds and evaluate the optimum size range in which this material should be concentrated.

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.

Recent dense media separation testwork has also proved effective at concentrating material at coarse particles size distributions. Magnetic separation has also proven effective at recovering wolframite, a para-magnetic tungsten mineral, however further work is underway to improve selectivity in this process and subsequent concentration.

Testwork has also demonstrated the efficacy of ore sorting when applied to material from Hatches Creek. Given the nature of the mineralisation, the wolframite / scheelite is generally isolated to specific rock types and ore bearing material is quite easily distinguished from non-ore bearing material resulting in significant rejection of barren material and high overall tungsten recoveries.

Collectively, ore sorting, in conjunction with gravity and magnetic separation has underpinned flowsheet development, and testwork has centred upon bulk testing and optimisation of these processes.
