CROESUS SAMPLING CONFIRMS GOLD-ANTIMONY SYSTEM,
WITH ASSAYS UP TO 13.3 G/T GOLD – NEW ZEALAND
First-pass reconnaissance sampling confirms high-grade gold-antimony mineralised material associated
with historical workings at the Croesus Project in the Reefton Goldfield, New Zealand, with in-situ bedrock
anomalism supporting follow-up targeting along the Croesus-Minerva trend.
- First-pass reconnaissance sampling at the Croesus Project in New Zealand has returned gold
grades up to 13.3 g/t Au (A1479) and antimony up to 6,990 ppm (0.7%) Sb (A1482), confirming
high-grade gold-antimony mineralisation across the Croesus-Minerva trend.
- The strongest gold results were returned from ex-situ historic ore-spillage material interpreted to
be related to historical mining, ore handling, ore-bin losses or haulage-route spillage. These
samples provide important exploration vectors but are not representative of in-situ grade, width
or continuity.
- In-situ bedrock sampling returned up to 1.58 g/t Au (A1483) from quartz-carbonate stockwork in
altered Greenland Group rocks, supporting follow-up exploration for structurally controlled
bedrock gold-antimony mineralisation along the Croesus-Minerva trend.
- The results support the Company’s exploration model for Croesus of a structurally controlled
gold-antimony system hosted in the Reefton region’s Greenland Group metasedimentary rocks.
- The Croesus Project sits at the southern end of New Zealand’s Reefton Goldfield, which 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.
- First-pass sampling at the Granite Creek tungsten target is complete; assays remain pending.
Critical Resources Limited (‘Critical Resources’ or the ‘Company’, ASX:CRR) is pleased to report first-pass
reconnaissance rock-chip, float and historic workings results from the Croesus Project, located on the
southwestern flank of the Reefton Goldfield on the West Coast of New Zealand’s South Island.
The Croesus Project forms part of the Company’s broader New Zealand gold and critical minerals portfolio.
The project hosts two distinct and spatially associated mineral systems: structurally controlled gold-antimony
lode mineralisation hosted in Greenland Group metasedimentary rocks, and greisen-hosted tungsten
mineralisation associated with the Barrytown Granite.
The current announcement reports results from the Croesus gold-antimony area only. Tungsten assays from
the Granite Creek / Barrytown Granite target are pending and will be reported separately once received.
The new results are significant because the highest-grade gold and antimony assays are clustered around
historical workings and interpreted ore-handling areas, while in-situ bedrock sampling has also returned
anomalous gold from quartz-vein and quartz-carbonate stockwork material (Figure 1). The results provide field

support for the Company’s exploration model and define clear targets for systematic follow-up work across
the Croesus gold-antimony trend.

and returned 1.58 g/t Au and 21 ppm Sb. Geological hammer shown for scale.
CROESUS GOLD-ANTIMONY SAMPLING RESULTS
The first-pass reconnaissance program at Croesus included selective rock, float and historic ore-spillage
sampling around historical workings, interpreted haulage routes and mineralised quartz-vein occurrences.
A total of 21 Croesus samples targeting gold-antimony mineralisation are reported in this announcement,
comprising 6 rock samples, 8 float samples and 7 historic ore-spillage samples. Sampling was reconnaissance
in nature and targeted visible veining, sulphides, iron staining, altered Greenland Group rocks and historically
disturbed material.
The strongest gold result was returned from sample A1479, a historic ore-spillage sample described as quartz
with sulphides and stibnite, which assayed 13.3 g/t Au and 2,240 ppm Sb. Additional significant results include
sample A1473, which returned 8.13 g/t Au from quartz with pyrite; sample A1476, which returned 2.56 g/t Au
and 242 ppm Sb from quartz with sulphides, pyrite and possible galena; and sample A1482, which returned
1.61 g/t Au and 6,990 ppm Sb from quartz containing chalcopyrite, stibnite and pyrite.
In-situ bedrock sample A1483 returned 1.58 g/t Au from quartz-carbonate stockwork in heavily altered
Greenland Group rocks. This result is considered important because it confirms gold anomalism in bedrock,
rather than solely in transported, float or historic ore-spillage material.

GEOLOGICAL INTERPRETATION
Taken together, the results validate the Company’s exploration model for Croesus in four steps. First, historical
mining at Croesus extracted high-grade gold from quartz-sulphide lodes hosted in Greenland Group rocks.
Second, the high-grade gold-antimony ore-spillage samples confirm that high-grade mineralised material
was present within the historical mining system. Third, the in-situ result from quartz-carbonate stockwork
(sample A1483, 1.58 g/t Au) confirms that gold mineralisation remains in bedrock, not only in transported or
ore-handling material. Fourth, this defines a clear vector for follow-up work: mapping and sampling to locate
the source structures along the Croesus-Minerva trend.
The Croesus results support the interpretation of a structurally controlled gold-antimony system associated
with quartz-sulphide veining and altered Greenland Group metasedimentary rocks. The association of gold
with stibnite-bearing and sulphide-rich quartz is consistent with the Company’s exploration model for the
Croesus-Minerva gold-antimony trend. The presence of anomalous gold in in-situ quartz-carbonate stockwork
provides a priority focus for follow-up mapping and sampling to identify source structures and test continuity
along strike.
The high-grade historic ore-spillage samples are interpreted to represent material derived from historical
mining and ore handling around the Croesus workings. While these samples are not representative of in-situ
grade or width, they are important because they confirm the presence of high-grade gold-antimony
mineralised material within the historical mining system and provide practical vectors for follow-up
exploration.
The in-situ result from A1483 provides direct support for bedrock-hosted mineralisation within altered
Greenland Group rocks. This supports the next phase of work targeting structurally controlled quartz-sulphide
veining and stockwork development along the Croesus-Minerva trend.
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.
ANTIMONY – A CRITICAL MINERAL
Antimony prices have increased substantially over the past two years due to supply constraints and export
controls. Antimony is a designated critical mineral in Australia, the United States and the European Union,
and is listed as a priority resource under Australia’s Critical Minerals Strategy 2025–2030. Global supply has
tightened after China introduced antimony export controls in September 2024. The New Zealand
Government has separately identified gold and antimony in the Reefton Goldfield as a focus of its critical
minerals work.
GRANITE CREEK TUNGSTEN TARGET
Tungsten was added to China’s export control list in February 2025 and, like antimony, is a designated critical
mineral in Australia, the United States and the European Union. The Company notes that sample assays from
the separate Granite Creek / Barrytown Granite target are pending. As a result, tungsten results from Granite
Creek are not included in this Croesus gold-antimony focused announcement. Granite Creek remains a
separate high-priority tungsten target associated with greisen alteration and quartz veining within the
Barrytown Granite. The Company will report the Granite Creek tungsten results separately once assays have
been received, validated and reviewed.

NEXT STEPS
The Company will advance the Croesus gold-antimony target through a focused program of follow-up
fieldwork. Priority activities will include:
- detailed geological and structural mapping of quartz-sulphide vein systems;
- systematic in-situ rock-chip and channel sampling where safe exposures are available;
- mapping and sampling around historical workings, ore-bin sites and interpreted haulage routes to vector
toward potential source structures;
- integration of Au, Sb, As and associated pathfinder geochemistry with mapped structures and historical
workings; and
- ranking of targets for potential trenching or drilling, subject to access, permitting and environmental
approvals.
Figure 3 – Location Map of Croesus Prospecting Permit in the Reefton Goldfield region, with legacy sampling.
Critical Resources Managing Director, Tim Wither, commented: ‘These results confirm the presence of a
gold-antimony system at Croesus and, importantly, demonstrate that mineralisation is present in bedrock
as well as historical mine material.
‘Antimony is a designated critical mineral in Australia, the United States and the European Union, and the
gold-antimony association we are seeing at Croesus sits squarely within the focus the New Zealand
Government has placed on the Reefton Goldfield. That gives the project relevance beyond gold alone.

‘The highest-grade samples come from historical ore-spillage material, which is not representative of in-situ
grade or width, but it confirms the system and points us toward the source. Our focus now is to map and
sample the source structures along the Croesus–Minerva trend and rank targets for drilling. We also expect
tungsten assays from the Granite Creek target shortly; these were submitted under a separate analytical
method.’

NEXT STEPS – NEW ZEALAND PORTFOLIO
Following fieldwork at Lammerlaw and Croesus, the Company’s near-term focus across the New Zealand
portfolio (Figure 4) includes:
- Croesus: First-pass field work completed over both the Granite Creek tungsten target and the Croesus-
Minerva trend. Assay results for the Granite Creek tungsten target are pending, with follow-up mapping
being planned to define the broader systems, subject to weather access.
- 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.
