HALLS PEAK PROJECT UPDATE - MULTI COMMODITY AND
CRITICAL MINERALS DISCOVERY PIPELINE
Major Gold–Antimony–Silver System Emerging at Amoco, Exceptional Silver at the Gibsons
Project, and land-access progressing at the Mayview Antimony Prospect.
- Petrographic analyses of maiden drill samples from Amoco confirm an affinity with a late‑stage
shallow orogenic Gold-Antimony-Silver bearing system overprinting earlier VHMS mineralisation,
analogous with the mineralisation style observed at Larvotto Resources’ (ASX:LVR) Hillgrove
deposits.
- Outcrop and float sampling at Amoco show high‑grade Au–Sb–Ag mineralisation potential,
including up to 17.9 g/t Au, 0.7% Sb and 53.2 g/t Ag.
- Maiden drilling at Amoco intersected numerous black shale units, that have the potential to host
additional multi‑commodities similar to the high‑grade silver‑bearing lodes at the Company’s
nearby Gibsons base metals Project, significantly expanding the exploration footprint.
- Critical Resources’ Gibsons Project hosts up to nine silver‑bearing lodes, including multiple zone
greater than 900g/t Ag, three lodes include exceptionally high‑grade silver, as previously
reported :
• 1.15m @ 3,780 g/t Ag (121.5 oz) (DDHA6)
• 1.6m @ 1,900 g/t Ag (61.1 oz) (PMR027)
• 2.0m @ 1,085 g/t Ag (34.88 oz) (CRRDD_14)
• 12.45m @ 331.63 g/t Ag (10.66 oz), incl.1.24m @ 1,750 g/t Ag (56.3 oz) (CRR21DD_01)
- Land‑access negotiations are progressing at the Mayview Antimony Prospect, located
immediately adjacent to Larvotto Resources Hillgrove Antimony‑Gold Operations. High‑grade
antimony and gold sample results up to 52.3% Sb and 2.71 g/t Au.
Critical Resources Limited (‘Critical Resources’ or the ‘Company’, ASX:CRR) is pleased to provide an update
from completed petrographic analyses of samples that confirm an affinity with a large, structurally controlled
orogenic gold–antimony–silver-bearing system at Amoco, complementing the extensive high‑grade silver
mineralisation modelled at Gibsons. This work advances the Company’s strategy to build a district-scale,
multi-commodity precious and critical minerals discovery pipeline within the New England Fold Belt, NSW.
AMOCO PETROLOGY STUDY
The Amoco gold-antimony project is located in the fertile New England fold belt ~19km southeast of Larvotto
Resources Limited’s (ASX:LRV) Hillgrove Antimony-Gold operations and ~14km east of Koonenberry Gold’s
(ASX:KNB) Enmore Gold Project along regional controlling structural trends. Petrographic analysis of ten drill
samples from the maiden drill program at Amoco has confirmed that the Project hosts a late stage

ASX:CRR
shallow-level orogenic lode system that was superimposed on the earlier volcanic-hosted massive sulphide
(VHMS) system.
Most drill samples consist of quartz-rich hydrothermal breccias and vein infill, with strong replacement textures
indicating multiple pulses of mineralising fluids. These fluids introduced sulphides, silica and carbonate, forming
zones containing up to ~20% sulphide minerals. Alteration includes quartz–sericite–pyrite assemblages with
local adularia, typical of epithermal–mesothermal conditions.
Halls peak area hosts two significant mineral systems:
• A Zinc-Lead-Silver-Copper-Gold volcanic hosted massive sulphide (VHMS) system.
• A fault controlled large orogenic system that hosts late stage fluids that introduced gold and antimony
in areas. Similar to the mineralisation style of the Hillgrove Antimony-Gold deposit (Larvotto Resources)
and the Enmore Gold field (Koonenberry Gold).
The observed characteristics of mineralised samples from Amoco drill samples are consistent with the style of
mineralisation being of hydrothermal ‘lode’ type, occurring as hydrothermal breccia and vein infill, as well as
portion of the intense replacement of immediate host rock (e.g. in breccia fragments).
The presence of arsenopyrite, quartz textures and occurrence of carbonate (calcite) in some samples infers
an affinity of the mineralisation style with that of a relatively shallow level orogenic gold system. The 2026
petrographic report strongly recommended further drilling of the areas of surface high grade gold, antimony,
silver and arsenopyrites to further understand the controls on high grade mineralisation. Samples of outcrop
and float mineralisation (Figure 1) at Amoco have returned up to 17.9 g/t Au, 0.7% Sb and 53.2 g/t Ag.

Table 1 – Previously reported mineralised rock sample highlights – Au, Sb and Ag analyses from Amoco.
Petrographic studies of the Amoco high grade Au-Sb mineralisation (Ashley 2024) noted ‘high values of Au,
As and Sb, and relatively low base metals (and Ag), together with mineralogy and quartz textures, are
considered to be consistent with an orogenic gold mineralised system. These characteristics contrast
significantly with the geological and geochemical setting of the Halls Peak massive sulphide system to the
west, and provide some analogy with the Hillgrove Au-Sb-As-W deposit.’
Recent re-interpretation of aeromagnetic survey (ASX:CRR announcement 20 March 2025) has outlined a
network of major fault structures (Figure 1). Modelling of the legacy and recent assay data supports the
geological interpretation of mineralised NE/SW structures, which are interpreted as key conduits for

hydrothermal activity, analogous to the nearby Hillgrove operations and gold mineralisation at the
Koonenberry Gold’s Enmore Gold Project.
Together, the petrographic results indicate that Amoco is a substantial, district-scale orogenic system with the
right mineral chemistry, alteration, and fluid signatures for potential higher-grade gold-antimony
mineralisation near surface and at depth. The combination of deeper arsenopyrite-bearing zones, broad
alteration envelopes and strong pathfinder responses provides a clear technical foundation for ongoing
targeting within the Amoco corridor.

structures (black dashed lines) with Gibson Base Metals Project.
GIBSONS PROJECT
The Company’s Gibson Project has an Inferred Mineral Resource of 840,000 tonnes @ 3.7% Zn, 1.5% Pb, 0.44%
Cu, 30 g/t Ag and 0.1 g/t Au (JORC 2012) (refer to ASX:CRR announcement 30 June 2023). The Gibson MRE
was defined from 47 drillholes (6,921m) across multiple campaigns and demonstrates the mineralised lodes
extend both laterally and vertically beyond current drilling density. Importantly, the resource remains open
along strike and at depth, and many of the highest-grade silver results reported during the December 2024
review sit outside or adjacent to the current resource wireframes — providing clear pathways for near-term
expansion.

ASX:CRR
Drilling at Gibsons confirms exceptional silver potential with multiple stacked silver-rich lodes, with extremely
high-grade silver reported across several horizons. More than 130 drill samples exceed 100 g/t Ag, with ten
samples over 940 g/t Ag, including standout intercepts of 3,780 g/t Ag, 1,900 g/t Ag and 1,750 g/t Ag. These
exceptional silver grades span multiple drilling campaigns across the Gibson Mineral Resource Estimate
envelope, confirming the presence of up to nine mineralised horizons, three of which contain consistently
ultra-high-grade silver (>900 g/t Ag).
Up to nine mineralised horizons have been modelled at Gibsons, three of which consistently carry silver
grades >900 g/t Ag. The lowest of these lodes hosts silver not in base-metal sulphides but as tetrahedrite
disseminated within intensely altered black shale—providing a parallel, structurally distinct silver system that
expands the exploration footprint. Near-surface high-silver intervals may also reflect supergene enrichment,
offering potential for shallow ounces. Highlighted high-grade silver intersections from Gibsons included in the
table below (refer to ASX:CRR announcement 4 December 2024):

Table 2 - Significant Silver values from Halls Peak drill campaigns. Note: CRR21DD_04 reached the assay
overlimit and was not retested.
The geological setting at Gibsons — multiple stacked lodes, strong structural control, black-shale enrichment,
and vertical mineral continuity — mirrors other large-scale lode-style silver and polymetallic systems. Gibsons
hosts two distinct silver mineralisation styles:
1. Massive sulphide–hosted silver associated with Zn–Pb–Cu lodes, responsible for many thicker
high-grade intervals.
2. Black shale–hosted silver, with silver occurring as tetrahedrite disseminated through intensely altered
shale. The standout PMR027 interval (1.6m @ 1,900 g/t Ag) with minimal base metals confirms this
second, high-grade structural system.
The Gibson Project geological understanding supports a broader exploration model that includes both
massive sulphide lodes and structurally prepared shale corridors. Future drilling will target down-dip extensions
of the three high-grade silver lodes, untested shale horizons, and step-outs designed to grow both metal
tonnage and grade. Together with Amoco, Gibsons and Mayview forms a critical part of a unified
district-scale multi-mineral (precious, base and critical) portfolio at Halls Peak.

MAYVIEW ANTIMONY PROSPECT
The Mayview Homestead Antimony Prospect lies adjacent to Larvotto Resources’ Hillgrove Antimony–Gold
Project (Figure 2). Field mapping confirmed antimony–gold mineralisation in historic surface and underground
workings, supported by standout rock-chip assays including 52.3% Sb, 38.3% Sb, 15.35% Sb & 2.71 g/t Au,
12.45% Sb & 2.18 g/t Au, and 11.2% Sb & 1.13 g/t Au.
Engagement with landholders is ongoing, with the Company aiming to complete a low-impact
soil-geochemistry survey over the ~270 m of mapped workings once access is secured. Early indications
suggest Mayview may form part of the southeastern extension of the Hillgrove-style orogenic Sb–Au system.
Figure 2 – Mayview Antimony Prospect with recent surface rock samples.
NEXT STEPS
The Company’s next phase of work across the Halls Peak Project will focus on advancing each prospect
through targeted, high-impact exploration programs that build on the strong technical foundations now
established.
At Amoco, the new petrographic results will be integrated into the structural and geological model to refine
priority targets aimed at testing the interpreted gold–antimony zones along strike and at depth. Permitting
activities and land-access agreements are ongoing to support the next stage of drilling.
At Mayview, the Company continues to engage constructively with landowners, with the intent to undertake
a low-impact soil-geochemistry survey across the historic antimony workings once access is secured.

(Criteria in this section apply to all succeeding sections.)
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 the
appropriate calibration of any
measurement tools or systems used.
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 (eg
submarine nodules) may warrant
disclosure of detailed information.
• Petrographic samples were selected by a qualified geologist
from Reverse circulation (RC) drill chips that were sampled in
1 metre down hole intervals as described below. Some
samples of large chips collected when compressed air was
utilised to dislodge down hole blockages.
• Samples personally delivered by hand to Paul Ashley
Petrographic and Geological Services, Armidale, N.S.W.
• The samples were submitted to Thin Section Australia Pty Ltd
in Brisbane, who prepared polished thin sections (PTS) from
each sample. The resulting PTS were examined
microscopically in transmitted and reflected light. Magnetic
susceptibility was measured on each sample and
photomicrographs taken of mineralogical and textural
features. A few samples were tested with dilute HCl to check
carbonate speciation
• The purpose of the petrographic examination was to
characterise the style of primary mineralisation in the
samples, hydrothermal alteration and infill, and the nature of
the original rocks.
• Reverse circulation (RC) samples were collected by a cone
splitter for one metre sample intervals. Reverse circulation
drilling was used to obtain 1 m samples from a nominal 3 - 5
kg weight was supplied to ALS for sample preparation
• Field duplicates were collected. Certified duplicates and
blanks were included in sample batch dispatched to ALS.
• To ensure industry standards, RC drill samples were
dispatched to ALS Minerals (Brisbane) and prepared and
analysed by the following methods.
RC samples were analysed by ME-ICP61 for 34 elements and gold by
Au-AA25
Drilling
techniques
Drill type (eg core, reverse circulation,
open-hole hammer, rotary air blast, auger,
Bangka, sonic, etc.) and details (eg 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.).

representivity of samples.
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.
Petrographic samples were selected by a qualified geologist from
logged RC samples.
RC samples were split using a rig-mounted cone splitter on 1m
intervals to obtain a sample for assay, of approximate weight 3 – 5kg.
RC drilling is an established method designed to minimise drilling-
induced contamination of samples, aimed to deliver a representative
sample of the interval being drilled.
Sample moisture was monitored, and water is blown out at each rod
change prior to resuming drilling. Hole terminated if sample is wet.
If the site location was deemed to have possible transported material,
either the soil sample was not taken, or taken from a different site.
The sample sizes are standard industry practice sample sizes collected
under standard industry conditions and by standard methods that are
considered appropriate for the medium being sampled, the
laboratory techniques employed and the type and style of
mineralisation which might be encountered at this project.
Sample sizes are considered appropriate for the style of mineralisation
sought.

applied and their derivation, etc.
Nature of quality control procedures
adopted (eg standards, blanks,
duplicates, external laboratory checks)
and whether acceptable levels of
accuracy (i.e. lack of bias) and precision
have been established.
• Petrographic samples were selected by a qualified geologist from
logged RC samples.
• RC samples were analysed by ALS Brisbane by ME-ICP61 for 34
elements via four acid digest and ICP-AES, gold by Au-AA25,
overlimit samples were analysed by Mn-OG62.
• The techniques and practices are appropriate for the sample
type and style of mineralisation.
• Individual field soil samples are stored in numbered, sealed plastic
sample bags for transport and at the laboratory.
• No geophysical tools were used to determine any element
concentrations.
• Reference standards and blanks were inserted in sample batch
