Viking Mines Limited (ASX: VKA, OTC: VKALF) ("Viking" or "the Company") is pleased to
report a major step forward in metallurgical testwork at the Linka Tungsten Project in Nevada,
USA.
Follow-up testwork focussed on both refinement of the gravity stage and first pass
rougher/cleaner flotation stage undertaken on a larger 10 kg sample has delivered an excellent
outcome with a combined gravity-plus-flotation concentrate grading 62.5% WO₃ at 59.8%
recovery - a step-change improvement from the 56.4% WO₃ at 46.0% recovery reported
previously.1
Commenting on the significance of these results, Viking Mines Managing Director & CEO
Julian Woodcock said:
“These results are yet another significant step forward for the Linka Project. The combined gravity
and cleaner flotation circuit is now delivering a world-class 62.5% WO3 concentrate at 59.8%
recovery - a meaningful uplift in recovery from the 46.0% reported in March, while maintaining a
premium concentrate grade.
“Just as importantly, continued refinement of the gravity stage has pushed our standalone gravity
concentrate to 66.6% WO3. With the result attained from a larger 10 kg sample, this repeatability
at scale gives us confidence in the flowsheet we are developing.
“The flowsheet itself remains deliberately simple using simple proven technologies, we avoid the
chemical complexity and high capital intensity that holds back many critical minerals projects. This
keeps Linka on a fast-track development path in a tier-one US jurisdiction.
“These results feed directly into the conceptual processing study underway with Mineral
Technologies as we de-risk the processing pathway ahead of our maiden drilling programme. With
APT pricing at all-time highs and the tungsten market in structural deficit, the strategic value of a
US-based, low-CAPEX scheelite producer continues to grow.”
LINKA GRAVITY CLEANER AND ROUGHER FLOTATION TESTWORK
Follow-up testwork on a 10 kg subset of the Linka Pit sample LKMET0004 has built on the
previously reported gravity-only results,1
with the addition of a first-pass rougher/cleaner flotation
circuit on the gravity tails (Figure 2). Key findings are summarised below:
• Premium saleable concentrate achieved, grading 62.5% WO₃ at 59.8% recovery - a step-
change improvement from the previously reported 56.4% WO₃ at 46.0% recovery.1
• Attained via combined gravity concentrate (66.6% WO₃ at 42.7% recovery) plus flotation
concentrate (54.3% WO₃ at 17.1% recovery) from a 1.2% sample feed grade.
• Refinements to the gravity separation method delivered a standalone gravity concentrate
(Figure 1), grading 66.6% WO₃ (from1
63.6% WO₃), with recovery confirmed at 42.7% (from1
42.4%).
• Rougher and cleaner flotation stages achieved a 54.3% WO₃ concentrate grade at
17.1% recovery, providing the basis for combining with the gravity concentrate.
• Initial observations from the flotation cleaning stages indicate further opportunity for
improvement and refinement via modifying reagent dosage to maximise final flotation
concentrate recovery and grade.

ASX:VKA, OTC:VKALF | vikingmines.com
RECOVERY STEP-UP FROM COMBINED CIRCUIT
The addition of cleaner flotation on the gravity tails lifts total recovery to 59.8% at a combined
premium concentrate grade of 62.5% WO3, comfortably above the >50% WO₃ saleable threshold
for scheelite concentrate. This is a meaningful step up from the 46.0% recovery at 56.4% WO₃
(gravity plus middlings) attained in the phase 2 testwork.1
Optimisation of the flotation reagent regime is now underway, with the objective of further lifting
flotation recovery while holding the combined concentrate grade above the >50% WO₃ saleable
threshold. With further work targeted at the cleaner stages, additional recovery upside is
expected. Updates will be reported to the market as the testwork is completed.
A VALIDATED, LOW-CAPEX PROCESSING PATHWAY
The ongoing metallurgical testwork program validates the "Rapid-Start" model that prioritises
low-cost physical separation over complex chemical processing. Refinement of the gravity circuit
on a 10 kg sample lifted the standalone gravity concentrate grade to 66.6% WO3. The ability to
produce a premium scheelite product through gravity alone - replicated at five-fold larger scale -
is a significant competitive advantage, enabling a simplified, modular plant design that can be
permitted and built in shorter timeframes compared to traditional on-site established facilities.
These results are being incorporated into the conceptual processing study underway with Mineral
Technologies to refine CAPEX estimates and plant design.

STRATEGIC POSITIONING IN THE US SUPPLY CHAIN
With global APT prices at US$3,050/mtu, the ability to produce high-grade concentrates via a
low-CAPEX model in Nevada establishes Linka as an increasingly strategic asset. As the US
Department of War and domestic manufacturers seek to secure "NATO-grade" tungsten supply
outside of traditional channels, Viking is positioning as a primary onshore solution.
NEXT STEPS
With the gravity and rougher/cleaner flotation operating conditions now established, the
metallurgical programme is moving into optimisation and variability testing across the four bulk
samples previously collected from the Linka Project area3
. Key next steps include:
• Flotation Reagent Optimisation: refinement of the rougher/cleaner flotation regime
to maximise flotation recovery while holding combined concentrate grade above the
>50% WO₃ saleable threshold.
• Variability Testing: application of the optimised gravity and flotation conditions to the
remaining bulk samples (Conquest, Hillside and Stockpile) to confirm flowsheet
performance across the project area.
• Comminution Testing: detailed comminution test suite on fresh samples to define
crushing and grinding energy requirements and ore abrasion properties, feeding into
plant design and OPEX estimations.
• Gravity Enhancements: Ongoing gravity separation tests at coarser grind sizes.
• Ore Sorting: Testing of a recently collected ~40kg sample by ore sorting technology.
• Modular Blueprint: finalising the conceptual processing study underway with Mineral
Technologies.
• Geological Understanding: 3D geology model completion using recently digitised
mapping and drillhole data.
• Maiden Drilling: with drill permitting now approved, the maiden drill programme at
Linka remains on track for the June 2026 quarter.

APPENDIX 1 – JORC CODE, 2012 EDITION – TABLE 1
JORC Table 1, 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
downhole gamma sondes, or handheld XRF instruments,
etc.). These examples should not be taken as limiting the
broad meaning of sampling.
Metallurgical Sample
Collection of loose rocks on surface from each of the 4 sample locations using an ultraviolet light (254nm wavelength) to
identify mineralised material to identify mineralised material. Samples collected were bagged in to calico and polyweave
bags and subsequently broken into smaller pieces to aid transportation to the metallurgical laboratory and facilitate
processing by the metallurgical laboratory.
Include reference to measures taken to ensure sample
representivity and the appropriate calibration of any
measurement tools or systems used.
Metallurgical Sample
Samples are deemed representative of the target mineralisation being sampled as they were identified using an ultraviolet
light which confirmed scheelite bearing mineralisation was sourced. It is unknown if the samples are representative of the
original insitu material due to rocks being collected from loose material on surface and not being insitu.
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
Metallurgical Sample
Loose rocks collected form surface and delivered to the metallurgical laboratory in 26 individually numbered calico bags.
Samples which corresponded to the parent (composite) sample were prepared by the laboratory by combining contents
from the designated bags, stage crushing to <3.35 mm, passing through a riffle splitter multiple times and blending to
homogenise. This blended sample was further processed through the riffle splitter to generate a representative sub-sample.
This sub-sample was then pulverised to minimum P80 <75 µm prior to being submitted for assay. This sub-sample is
considered accurate with sample mineralogy not expected to have caused sampling issues.
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.).
Not applicable, no drilling being reported.
Drill sample
recovery
Method of recording and assessing core and chip sample
recoveries and results assessed.
Not applicable, no drilling being reported.

grade and whether sample bias may have occurred due to
preferential loss/gain of fine/coarse material.
Not applicable, no drilling being reported.
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.
Not applicable, no drilling being reported.

Metallurgical Sample
The sample preparation, blending and sub-sampling techniques are appropriate for this material’s mineralogical makeup.
Quality control procedures adopted for all subsampling
stages to maximise representivity of samples.
Metallurgical Sample
No QAQC samples were utilised by Viking. The metallurgical laboratory inserted blanks and standards which contained WO3
grades similar to the assayed samples WO3 head grades.
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.
Metallurgical Sample
Insitu material has not been sampled. No duplicates taken. On completion of the metallurgical testwork programme, the
metallurgical balance will be used to verify the head grade assays.
Whether sample sizes are appropriate to the grain size of the
material being sampled.
The Competent Person considers the current methods and processes described as appropriate for this style of
mineralisation due to the grade of mineralisation being reported. Sample size of the metallurgical sample is appropriate
both due the grades being grade of the mineralisation and the large samples collected.
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.
Metallurgical Sample
The assaying technique utilised a lithium metaborate/lithium tetraborate (50/50) fusion melt followed by nitric acid
dissolution with the resulting solution analysed by an ICP OES/MS. This technique is considered to be 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.
No data has been reported of this type.
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.
Metallurgical Sample
No QAQC samples were utilised by Viking. The metallurgical laboratory inserted blanks and standards which contained WO3
grades similar to the Viking’s assayed samples WO3 head grades. This achieved acceptable levels of accuracy and removed
bias.

Linka Mine: The area was staked in 1941 by Steve Linka of Austin, NV. In 1943-44, the mine produced 2,420
tons of ore averaging 0.69% WOз. Consolidated Uranium Mines purchased the property in 1953, sunk a
vertical shaft to 210 feet and drove approximately 1,000 feet of drifts and cross-cuts on the 150’ level.
Additional production included; 4,000 tons of ore averaging 0.98% WOз between 1951 and 1956 and 60,000
tons averaging 0.40% WOз between 1955 and 1956. The mine closed when the Government buying program
ended. Mine workings include a 100’ X 50’ open-pit 25 feet deep, a 210’ shaft with approximately 1,500 feet of
drifts and cross-cuts. Shrinkage stopes extend from the 150’ level to the surface (Stager and Tingley, 1988).
In 1951, the Linka Mine was optioned to Hugh Chesser, Reno, NV. Hugh Chesser estimates shipments to
Metals Reserve Corporation during WWII totalled 2,673 tons averaging 0.72 percent WOз.

Criteria JORC Code explanation Commentary
Cache Creek Exploration held the properties in the early 1970’s and conducted geological and geophysical
programs. Duval Corporation optioned the properties in the mid-1970’s, did geological studies but no drilling.
Min-Ex drilled the property in 1977-78, with a total of 73 drillholes recorded (eight DDH and 64 wide-spread
percussion drillholes). Note: Not all drillhole locations have been established, with 69 holes digitised and 1
hole estimated (total 70) and three percussion holes with unknown location. Exploration activity completed by
Minex included drilling, surface and underground geological mapping and sampling, minor geophysical
magnetic survey with 10,400 linear feet collected (inconclusive results), 6,500ft of bulldozer trenching and
mapping.
Stager and Tingley, 1988 estimate total production at the Linka mine at 25,670 units WOз (1943-56).
Linka-Conquest Mine: The mine was discovered in 1941 but did not start production until 1943 when Gale
Peer sunk a two-compartment inclined shaft to 130 feet. Workings off the shaft were at the 50 and 100 foot
levels. During WW II mined and shipped 390 tons of ore averaging 2.7% WOз. Additional shipments after the
War averaged over 1.0% WOз, but the tonnage is unknown. Last work on the 100’ level exposed a zone 40’
long, 12’ to 20’ wide, open to the northeast with a grade of <0.4% WOз. Stager and Tingley, 1988, estimate
total production at 5,208 units WOз (1944-56).
Stager and Tingley, 1988 estimate total production at the Conquest mine to be 5,208 units WOз (1944-56)
Geology Deposit type, geological setting and style of mineralisation
Linka Project: The area is underlain primarily by sedimentary rocks; it includes an outcrop of massive
limestone of Ordovician age (Upper Plate) overlain in thrust contact by chert and shale of Ordovician Vinini
Formation (Lower Plate). The limestone is intruded locally by granitic rocks of Jurassic age, and the tungsten
deposits occur in the limestone along the granite contact (Stager and Tingley, 1988)
Linka-Conquest Mine - Granite intrusive rocks (Jg) and aplite dikes intrude cherts, shales and limy members of
the Vinini Formation (Ov) in the Upper Plate of the Roberts Mountain Thrust. Scheelite-bearing skarn formed at
the contact.
Miocene age Bates Mountains tuff (Tbm) covers any extension of the mineralization to the northeast.
Linka Mine – Scheelite occurs in lenses and tabular masses of skarn at the contact between Ordovician
Antelope Valley Limestone (Lower Plate of the Roberts Mountain Thrust) and granitic intrusive rocks. The
contact zone is cut by igneous dykes and high-angle faults. Exposures are poor. Granite rocks west of the
contact zone are covered by post-mineral volcanic rock and sediments of Big Smokey Valley.
Antelope Valley limestone east of the contact zone is nearly vertical. The contact zone is about 40 feet wide.
Drilling in the 1970’s shows that, at depth, the contact zone may flatten to the east, then steepen.
Scheelite, with traces of chalcopyrite and molybdenite are the only ore minerals recognized.
Linka-Hillside - The Hillside incline shaft is about half way between the Conquest and Linka Mines. The shaft is
inclined at ~47° and is approximately 100 feet deep. In 1978, when the area was visited by Richard Jones and
Harold Bonham, geologists at the Nevada Bureau of Mines and Geology, there were no drifts or cross-cuts off
the shaft. Here the rocks are more thinly bedded and contain more hornfels then sediments at the Linka shaft.
Lenses of scheelite-bearing skarn in the Hanson Creek Fm are at the surface and a lens of mineralized skarn
within the Antelope Valley Limestone occurs in the shaft (Stager and Tingley, 1988).
