Multiple Gold-Antimony Exploration Targets at Halls Peak
Following Geophysical Survey Interpretation
Highlights
• Identification of Untested Structural Corridors: The geophysical survey has revealed previously
unrecognized structural corridors with the potential to host significant gold-antimony mineralisation,
unlocking new exploration opportunities.
• Magnetic Data Confirms Deep-Seated Fault Systems: Advanced filtering techniques have identified
deep-rooted fault systems, which are critical for fluid flow and ore deposition, enhancing the
geological model of the Gibsons Prospect area within the Halls Peak project.
• Potential for Multiple Mineralisation Styles: The reinterpretation suggests that the Gibsons Prospect in
the Halls Peak Project may host both Hillgrove-style gold-antimony mineralisation in addition to the
mineralisation associated with base metal systems, increasing the project's potential.
• Refined Exploration Focus Based on New Geophysical Data: The latest data allows for a more targeted
exploration approach, prioritizing structural intersections and magnetic anomalies indicative of
mineralisation.
• Multi-prospect project: These new key findings together with recent sampling and geophysical findings
received across the Halls Peak project, provides numerous additional targets at the Mayview, Gibsons
and the Amico Grid prospects
• Significant Antimony Mineralisation from Drilling: Previous drilling has confirmed substantial antimony
mineralisation, 20,400 g/t Sb over 1.15m (DDHA6), 10,000 g/t Sb over 1.24m (CRR21DD_01), elevated
antimony values in at least 11 drill holes, with multiple samples exceeding 500 g/t Sb.
• High-Grade Silver Intercepts: Further analysis of past drilling has also revealed exceptionally high-grade
silver mineralisation at the Gibsons Project within Halls Peak, as detailed in the December 4, 2024,
announcement: 3,780 g/t Ag (121.5 oz/t) over 1.15m (DDHA6), 1,900 g/t Ag over 1.38m (PMR027), 1,750
g/t Ag over 1.6m (PMR027), More than 130 drill core samples assayed over 100 g/t Ag, 10 samples
exceeded 940 g/t Ag (30 oz/t).
Critical Resources Limited (ASX: CRR) is pleased to announce the results of a comprehensive
geophysical review and airborne magnetic interpretation over the Halls Peak Project, covering
exploration licences EL 4474, 7679, and 9293 in the New England area, NSW. The study, conducted
by Eureka Consulting Pty Ltd, has identified significant structural features that are highly
prospective for gold-antimony mineralisation, aligning with a Hillgrove-style system.
The reinterpretation of aeromagnetic data has highlighted structural complexities that provide
ideal conditions for gold-antimony mineralisation. These systems are believed to have been
superimposed onto the existing Permian sedimentary package, which hosts high-grade Zn-Pb-CuAg-Au mineralisation, as evidenced by previously discovered massive sulphide lodes. This finding
significantly expands the exploration potential at the Gibsons Prospect area within Halls Peak by
introducing a secondary mineralisation style beyond the established base metal systems.

The airborne survey, originally acquired using a helicopter-borne VTEM and magnetic data
acquisition systems by Geotech Limited, was initially designed to target massive base metal
sulphide mineralisation. The new geophysical interpretation has unveiled fault structures that could
act as key conduits for gold-antimony deposition, reinforcing the project’s potential to host a
structurally controlled mineral system comparable to Larvotto Resources Limited’s (ASX: LRV)
Hillgrove Antimony-Gold operations.

Identification of Major Fault Structures and New Gold-Antimony Targets
The aeromagnetic survey has outlined a network of major fault structures interpreted as key
conduits for hydrothermal activity responsible for Hillgrove-style gold-antimony mineralisation.
These faults, trending NE-SW and NW-SE, align with historical mineralized trends and known goldantimony occurrences, closely resembling the structural framework at the Hillgrove deposit.
The reinterpretation has refined the location and orientation of previously known faults while
identifying secondary and splay faults. Cross-cutting relationships between major and minor faults
suggest zones of increased deformation and fluid interaction, prime areas for gold-antimony vein
systems. Advanced filtering techniques (First Vertical Derivative, Tilt Derivative, and Edge
Detection) have also identified magnetic discontinuities indicative of deeply rooted structures,
potentially associated with major lithological contacts or intrusive events influencing
mineralisation.
Up to 36 high-priority exploration targets have emerged within faulted zones that likely served as
mineralising conduits. Structural intersections, known to host gold-antimony mineralisation in similar
settings, display intense magnetic variations, suggesting alteration zones. Additionally,
underexplored fault blocks with magnetic anomalies indicative of hydrothermal activity have
been identified for ground-truthing, geochemical sampling, and potential drill testing. Some faults
extend beyond previously mapped limits, expanding the prospective ground at Halls Peak and
warranting further structural mapping and surface sampling.

Enhanced Geological Understanding of the Gold-Antimony System at Halls Peak
Recent geological and geophysical studies at Halls Peak have significantly advanced the
understanding of its gold-antimony mineralisation. Reprocessed aeromagnetic data and structural
interpretations suggest that the mineralisation is strongly controlled by deformation events, with
key fault structures playing a crucial role in metal deposition. Additionally, the recognition of an
alternative mineralisation style highlights the potential for late-stage Hillgrove-style gold-antimony
systems, further expanding the exploration model for the area.
Improved Structural Interpretation
•
Reprocessed aeromagnetic data has provided a clearer geological framework, enhancing
the understanding of mineralisation at Halls Peak.
•
The Hillgrove-style gold-antimony system is now recognized as being strongly structurally
controlled, with mineralisation linked to key deformation events.
•
The alignment of historically mapped gold-silver-antimony occurrences within interpreted
fault zones further validates the aeromagnetic interpretation.
Page 5 of 17
Recognition of Alternative Mineralisation Style
A key development in recent studies is the recognition of a different style of mineralisation,
indicating the potential for late-stage Hillgrove-style gold-antimony systems. These systems are
thought to have been superimposed onto the Permian sedimentary package that hosts highgrade Zn-Pb-Cu-Ag-Au mineralisation, as evidenced by massive sulfide lodes already discovered.
The proposed system comprises large orogenic gold-antimony fault vein and quartz stockworkbreccia mineralisation, believed to have formed within deep-seated fault structures extending for
hundreds of meters.
Interpreted Structures Coincident with Anomalous Au and Sb Discovered in the Amoco Grid
Geochemical data for gold rock chip samples have been overlayed on the interpreted structures.
This has provided a number of focused targets to be examined and sampled on the ground
where Amoco gold anomaly data plots on major structures. These intersections could potentially
host gold clustering, along structures, and especially when structures intersect. The Amoco Grid
hosts highly anomalous rock chip and soil samples, over a length of over 1,000 metres from east to
west, with elevated gold mineralisation at 17.9g/t, 12.9 g/t and 10.4 g/t, antimony at 0.53% and
silver at 80g/t (refer to ASX Release November 8 2024).

significant gold-antimony-silver system within structurally controlled mineralized corridors.
Gibson’s Prospect MRE
Critical Resources Limited had completed a maiden JORC (2012) compliant Mineral Resource
Estimate (MRE) for the Halls Peak Project in New South Wales following a series of successful drilling
programs. The 47 diamond core drill holes, completed over four separate campaigns, totaled
6,921 meters and confirmed the presence of multiple stacked lodes containing both base metals
(zinc, lead, copper) and precious metals (silver, gold). The drilling has expanded the scale of
known mineralization both laterally and vertically, reinforcing the large-scale potential of the Halls
Peak System. The Inferred Mineral Resource is estimated at 840,000 tonnes grading 3.7% zinc, 1.5%
lead, 0.44% copper, 30 grams per tonne silver, and 0.1 grams per tonne gold at a 2.0% zinc cut-off
grade. Importantly, mineralization remains open along strike and at depth, presenting a clear
opportunity for further resource expansion through follow-up drilling.
Pathway for Future Exploration
Based on these findings, a well-structured systematic exploration program is planned to confirm
and advance the newly defined targets.
•
Geochemical Sampling & Surface Mapping:
o
Detailed fieldwork will be undertaken to validate aeromagnetic anomalies and structural
intersections.
o
Soil and rock chip sampling will be conducted along key fault traces to detect pathfinder
elements indicative of gold-antimony mineralisation.
•
Ground Geophysics (Magnetics & Induced Polarization - IP):
o
High-resolution ground magnetic surveys over select targets to refine the structural
model.
o
IP surveys to detect chargeability anomalies associated with sulphide-rich quartz veins.
•
Drill Target Definition & Initial Drilling Program:
o
Once geochemical and geophysical validation is completed, high-priority targets will be
identified for drill-testing.
o
The focus will be on major structural intersections where multiple fault systems converge.

Commentary
•
The heliborne geophysical survey was
undertaken by contractors Geotech Ltd.
(Perth, WA and Aurora, Canada). The
survey used a helicopter with a magnetic
sensor attached to the suspended EM
transmitter loop cable of the VTEM time
domain EM system. The VTEM survey data
used north-south oriented flight lines with
a line separation of 100 metres and a
magnetometer sensor height of nominal
92 metres above terrain. This height is
determined by the physical suspension of
the caesium sensor along the helicoptersuspended EM system (to support the
transmitter loop and receiver located at
70 metres above terrain). The 22 metre
height difference of the EM system to the
magnetometer sensor is an offset
designed to reduce the transmitted EM
signal
inducing
noise
into
the
magnetometer. Data was reprocessed
by Eureka Consulting Pty Ltd to enhance
structural interpretations and identify
mineralisation controls. Advanced filtering
techniques (First Vertical Derivative, Tilt
Derivative,
Edge
Detection)
were
applied.
