NEW ZEALAND - GRANITE CREEK - 16.63% WO3 CHANNEL
SAMPLE CONFIRMING HIGH-GRADE TUNGSTEN SYSTEM
First-pass sampling confirms high-grade scheelite mineralisation in bedrock at the Granite Creek tungsten
target, including a channel sample across the true width of an exposed quartz-scheelite vein.
- High-grade channel result: Channel sampling returns 0.41 m at 16.63% WO₃ (A1419) from an in-
situ quartz vein containing visible scheelite. The channel was collected perpendicular to the vein
and is considered to represent true width at the sample location.
- Repeatable high grades across the target: Nine of the 25 Granite Creek samples returned high-
grade tungsten results between 0.67% and 16.63% WO₃, including six samples above 1% WO₃
and three above 2% WO₃, confirming the high-grade tungsten mineralisation identified by
historical exploration.
- Multiple high-grade bedrock occurrences over 600m: Outcropping quartz veins returned high-
grade tungsten including 2.21% WO₃ (A1440), 1.61% WO₃ (A1412), 0.90% WO₃ (A1417) and 0.67%
WO₃ (A1402).
- Mineralised footwall: A separate adjoining 0.20 m footwall was sampled returning 3,820 ppm W
(A1420) indicating elevated tungsten extends into the altered wall rock immediately adjacent
to the high-grade vein.
- Scale potential: Scheelite-bearing float occurs in drainages on both flanks of the Barrytown
ridge. Historical sampling at Little Granite Creek to the north, returned up to 26.6% WO3,
supporting potential for a mineralised system that extends beyond the Granite Creek target.
- A critical metal in structural deficit: With tungsten near multi-year highs (~10x its long-run
average), China controlling ~80% of supply and tightening exports, a new high-grade tungsten
system in a stable Western jurisdiction like New Zealand is scarce and strategically valuable.
- Advanced drill targets: Historical and modern datasets substantially de-risk targeting. Next steps
include follow-up mapping and an exploration permit application before drill testing.
Critical Resources Limited (‘Critical Resources’ or the ‘Company’, ASX:CRR) is pleased to report final tungsten
assay results (Appendix A) from first-pass mapping and sampling at the Granite Creek Tungsten target (Granite
Creek) within the Croesus Project (Croesus) near Barrytown on the West Coast of New Zealand’s South Island.
The program confirmed high-grade scheelite mineralisation associated with quartz veining and greisen
alteration within and adjacent to the Barrytown Granite. The standout result was returned from channel
sample A1419, which assayed 0.41 m at 16.63% WO₃ from an in-situ quartz-scheelite vein. Modern sampling
identified multiple mineralised bedrock and float occurrences over at least 600 m of the Granite Creek target
area, supporting the interpretation of a broader quartz-vein and greisen-hosted tungsten system rather than
an isolated occurrence.

Granite Creek also benefits from detailed historical mapping and sampling that has already defined
numerous mineralised veins, greisen zones and scheelite occurrences. The current program has partially
validated this historical dataset and provides an advanced framework for focused drill-target definition.
Scheelite (calcium tungstate) is one of the two principal tungsten minerals worldwide and is readily identified
in the field by its distinctive blue-white fluorescence under ultraviolet light (Figure 1). Scheelite is generally
amenable to conventional gravity and flotation processing, although metallurgical performance at Granite
Creek is yet to be tested.
The Company’s immediate priority is to integrate the historical and modern datasets, complete targeted
confirmation work and prepare a subsequent exploration permit application over the priority Granite Creek
target area. Subject to permit grant, access and environmental approvals, this provides a clear pathway
toward initial drill testing.
Critical Resources Managing Director, Tim Wither, commented: ‘These are strong, repeatable tungsten
grades. The 0.41 metre channel assayed 16.63% WO₃ across the full width of an in-situ quartz-scheelite vein
— a true-width result, not a selected high-grade chip. And it is not a one-off: nine of our 25 samples
returned high-grade tungsten, including six above 1% WO₃, and three above 2% WO₃, over more than 600
metres of the target.
‘High-grade scheelite float on both flanks of the Barrytown Granite ridge points to a system extending well
beyond the immediate target. The timing is significant — tungsten has risen roughly tenfold off its long-run
average, China controls around 80% of global supply and is tightening exports, and the market is short of
secure supply from stable Western jurisdictions.
‘This first-pass sampling has validated key parts of a substantial historical dataset, letting us move directly
to focused target confirmation and an exploration permit application, ahead of maiden drill testing.’

GRANITE CREEK TUNGSTEN RESULTS
The first-pass program comprised geological mapping and channel, rock and float sampling of quartz veins,
greisen alteration and altered granite within the Granite Creek target area. The strongest result was returned
from channel sample A1419, which assayed 0.41 m at 16.63% WO₃ from an in-situ quartz-scheelite vein. The
channel was collected perpendicular to the vein and represents the true vein width at the sample location.
A separate adjoining 0.20 m footwall sample, A1420, returned 3,820 ppm W, indicating that elevated
tungsten extends beyond the quartz vein into the immediately adjacent altered granite.
Additional significant in-situ results include:
• A1440: 2.21% WO₃ from scheelite-bearing quartz;
• A1412: 1.61% WO₃ from granite vein selvage containing possible scheelite;
• A1417: 0.90% WO₃ from a 0.15 m quartz vein in granite;
• A1402: 0.67% WO₃ from a 0.05 m quartz vein containing visible scheelite;
• A1418: 3,430 ppm W from greisen-altered granite with quartz veinlets; and
• A1408: 2,920 ppm W from quartz-vein and granite-selvage material.

ASX:CRR
Significant float samples from Granite Creek results include:
• A1411: 8.01% WO₃ from scheelite-bearing quartz;
• A1409: 1.85% WO₃ from quartz containing sulphides and scheelite;
• A1416: 1.41% WO₃ from quartz containing scheelite and possible tourmaline; and
• A1407: 0.83% WO₃ from quartz and pegmatitic material.
Modern sampling identified multiple mineralised bedrock and float occurrences over at least 600 m of the
Granite Creek target area. The distribution of results supports the interpretation of a broader quartz-vein and
greisen-hosted tungsten system rather than a single isolated high-grade occurrence.
High-grade scheelite-bearing float has now been recorded in drainages on both flanks of the Barrytown
Granite ridge — at Granite Creek in the current program and at Little Granite Creek, where historical sampling
returned tungsten grades of up to 26.6% WO3 (ASX:CRR announcement 6 August 2025).
High-grade float in separate catchments draining opposite sides of the ridge indicates that scheelite is shed
from a broad area of the granite and its margins, supporting potential for a mineralised system that extends
well beyond the immediate Granite Creek target. Float is transported material and is not in-situ; reported
grades are selective and are not representative of average grade.
HISTORICAL DATA PROVIDES AN ADVANCED TARGET FRAMEWORK
Granite Creek has been subject to detailed historical geological mapping and sampling that identified
numerous quartz veins, greisen alteration zones and scheelite-bearing occurrences associated with the
Barrytown Granite. Historical selective sampling undertaken by Mineral Resources NZ Limited in 1988
reportedly returned grades of up to 42.6% WO₃ from scheelite-rich quartz and greisen material. Historical
float samples from Granite Creek and Little Granite Creek also reportedly returned 26.6% WO₃ and 19.9%
WO₃ (refer announcement 8 April 2026).
These historical samples were selective and are not representative of average grade, mineralised width or
continuity. However, the mapped locations, geological observations and assay results provide a detailed
framework for modern exploration.
The current Critical Resources program has partially validated the historical interpretation by confirming:
• 0.41 m at 16.63% WO₃ from a channel sample across an in-situ quartz-scheelite vein;
• multiple additional in-situ samples returning between 0.67% and 2.21% WO₃;
• elevated tungsten within altered granite adjoining the high-grade vein; and
• mineralised bedrock and float occurrences extending over at least 600 m.
The combined historical and modern datasets substantially reduce the requirement for broad first-pass
exploration. Remaining work can focus on confirming the geometry and continuity of priority veins,
completing targeted channel sampling and defining targets for initial drill testing.
The historical exploration results are from Mineral Resources NZ Ltd (1988; MR1530) and by AMOCO Minerals
NZ Ltd (1981-82)(MR1367), CanAlaska Ventures Ltd (2006)(MR4367), Lime and Marble Ltd (1971)(MR1282).
The results are considered suitable for target generation and reconnaissance assessment. The historical
results are considered material to the Company because they define priority targets for the recently
completed field program, support the geological exploration basis for the permit, and represent the most
systematic sampling dataset available for the Granite Creek and Little Granite Creek tungsten system. During

the completed field program, the team confirmed greisen alteration at Granite Creek documented by
Mineral Resources NZ Ltd in 1988. The historical reports document available information and has been

TUNGSTEN — A CRITICAL METAL IN STRUCTURAL DEFICIT
Tungsten is one of the hardest and densest metals known and has few effective substitutes in its primary
applications. It is essential to cemented-carbide cutting and drilling tools, defence applications including
armour-piercing munitions, aerospace alloys, and electronics and semiconductor manufacturing. Tungsten
is listed as a critical mineral by New Zealand, Australia, the United States and the European Union.
Global supply is highly concentrated. China accounts for approximately 80% of world tungsten mine
production and a similar share of downstream processing. Since 2023 China has progressively tightened
control of tungsten exports, adding ammonium paratungstate (APT) and other tungsten products to its
export-control list in February 2025 and, in December 2025, restricting authorised tungsten exports to a small
number of licensed companies for 2026–27. These measures have removed a large share of traditional
Western supply.
The result has been a sharp tightening of the Western market. APT — the key tungsten benchmark — was
assessed at around US$3,000–3,200 per metric tonne unit (mtu) CIF Rotterdam in early June 2026, multi-year
highs and roughly ten times its long-run average of approximately US$300/mtu (Fastmarkets; Shanghai
Metals Market). High-grade tungsten deposits in stable Western jurisdictions are rare, and new mines typically
take five to seven years to permit and build. With limited new supply outside China and Canaccord Genuity
forecasting tungsten demand to grow 47% to 2035, market analysts expect the market to remain in structural
deficit. This environment places a clear premium on new, secure tungsten supply in stable Western
jurisdictions such as New Zealand.

tenfold since its long-run average. Source: Fastmarkets (APT 88.5% WO₃, CIF Rotterdam/Baltimore May 2026).

ALIGNMENT WITH NEW ZEALAND’S CRITICAL MINERALS STRATEGY
Tungsten is included on New Zealand’s Critical Minerals List and is identified by the New Zealand
Government as a mineral with potential for domestic production. The Government’s Minerals Strategy to
2040 supports the responsible development of domestic mineral opportunities, increased economic value
and more resilient critical-mineral supply chains.
The high-grade Granite Creek results align with these objectives by confirming a prospective domestic
tungsten target within the Barrytown Granite. Detailed historical exploration, now partly validated by modern
mapping and assay results, provides an advanced foundation for progressing the target towards drilling.
Subject to the grant of a subsequent exploration permit and the required access and environmental
approvals, Granite Creek provides a clear opportunity to contribute to the development of New Zealand’s
critical-minerals sector and secure international tungsten supply chains.
ESTABLISHED WEST COAST MINING REGION
The Croesus Project lies within an established and expanding West Coast minerals province. At Barrytown,
Tāiko Critical Minerals (NZX:TCM) is advancing its consented Barrytown Mineral Project for ilmenite, garnet,
zircon and rare earth elements.
The Croesus Project lies on the southwestern flank of the Reefton Goldfield, a historic field that has reportedly
produced approximately two million ounces of gold from orogenic quartz-vein systems hosted in Greenland
Group rocks. The region also hosts Rua Gold Inc’s (TSX: RUA) Reefton Project and Endura Mining’s Snowy River
Project, approximately 20 km from Croesus, currently under construction.
The region has a long history of gold and coal mining, established road, rail and port infrastructure, a skilled
local workforce, and strong community and government support for responsible resource development —
reflected in the New Zealand Government’s goal of doubling national mineral exports to NZ$3 billion by 2035.
This established mining setting supports the pathway to access, permitting and development at Granite
Creek.
NEXT STEPS – PATHWAY TO DRILLING
The Company will now focus on integrating the detailed historical dataset with the new mapping and assay
results to finalise priority drill targets at Granite Creek. Planned work includes:
- targeted geological and structural mapping of the principal quartz-scheelite veins and greisen zones;
- additional channel sampling where required to confirm grade distribution and vein geometry;
- integration of historical maps, sample locations and modern results into a consolidated geological
model;
- definition of priority drill targets; and the preparation of an exploration permit application over the priority
Granite Creek target area.
The Company is targeting lodgement of an exploration permit application over the Granite Creek target in
the second half of 2026, with maiden drill testing to follow subject to permit grant and the required access
and environmental approvals.

The extensive historical dataset, now partly validated by modern sampling, means broad first-pass regional
exploration is not required before progressing toward drilling. Subject to the grant of a subsequent
exploration permit and the required access and environmental approvals, Granite Creek has a clear
pathway to initial drill testing.
NEXT STEPS – NEW ZEALAND PORTFOLIO
Following field work at Lammerlaw and Croesus, the Company’s near-term focus across the New Zealand
portfolio includes:
- Cap Burn / Rock and Pillar: First-pass RC drilling has confirmed structurally controlled gold mineralisation
in the TZ4 schist beneath the Cap Burn Fault, consistent with Santana Minerals (ASX:SMI) Rise and Shine
discovery model. The down-plunge extension below the TZ4-TZ3 boundary remains open and is the
primary target for a follow-up RC drill program now being designed. Soil-geochemistry mapping is
ongoing along the Cap Burn Fault and into the adjacent Rock and Pillar permit to assess strike continuity
of the mineralised corridor ahead of drilling (refer ASX:CRR announcement 25 March 2026).
- Silver Peaks / Tokomairiro: Desktop review and targeting advancing; land access discussions ongoing.

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.
• Include reference to
measures taken to ensure
sample representivity and

Material to the Public Report.
• A total of 25 samples were collected from the Granite Creek tungsten
target during April 2026, comprising 14 selective in-situ rock samples,
nine float samples, one continuous channel sample and one
adjoining footwall channel sample. Sampling targeted exposed
quartz veins, greisen-altered granite, vein selvages and mineralised
float containing visible or suspected scheelite.
• Channel sample A1419 was collected continuously across the full
exposed 0.41 m width of an in-situ quartz-scheelite vein. The channel
was oriented perpendicular to the vein and is considered to be the
true width at the sample location.
• A1420 was collected separately across 0.20 m of the immediate
footwall adjoining A1419 and has not been combined with the vein
sample. Other rock and float samples were selectively collected
during reconnaissance exploration and are not representative of
average grade, mineralised width or continuity. Float samples are ex-
