Overview
Chalice Mining Limited (“Chalice” or “the Company”, ASX: CHN) has refined its gold-copper exploration strategy in the West Yilgarn and is pleased to advise that reconnaissance exploration across its ~4,600km[2] Barrabarra Project in WA has identified two significant new gold targets and extensive areas of newly recognised greenstone belt geology.
The Recherche West and Warspite gold targets have been identified from regional soil geochemical surveys undertaken over prominent magnetic and structural trends identified from the Company’s high quality geophysical and geological datasets.
Chalice has conducted a significant multi-year, multi-commodity reconnaissance exploration program in the area since 2021 as part of its broader strategic focus on unlocking the mineral potential of the West Yilgarn Province beyond the tier-1 Gonneville deposit. The newly identified areas are almost entirely undrilled, highlighting the gold-copper prospectivity of the region.

Chalice Mining CEO and Managing Director, Alex Dorsch, said: “The discovery of the Gonneville deposit effectively unlocked a new mineral province along the western margin of the Yilgarn Craton – one that is still at an early stage in its discovery history. Building on the Gonneville discovery, Chalice’s exploration team has made solid progress in identifying new areas with strong discovery potential.
“This work has culminated in delineation of two new very large gold targets, one of which is hosted within an unrecognised greenstone belt, and another in the Koolanooka greenstone belt, both of which are planned for drilling later this year.
“We intend to systematically explore these targets to see if we can make further breakthrough discoveries. Given the size of the deposits found to date in the West Yilgarn – Gonneville with >17Moz PGE-Au and Boddington with >40Moz of gold – we believe this low-cost exploration is clearly worth pursuing in parallel with ongoing Pre-Feasibility work on the Gonneville Project.”
West Yilgarn Province
Chalice’s ~10,000km[2] West Yilgarn licence holding was predominantly staked in early 2020 following the greenfield Gonneville PGE-Ni-Cu-Co discovery by Chalice’s geologists. The licence holding has been subsequently expanded over time through new staking and earn-in agreements.
The entire licence holding was effectively unexplored pre-Chalice, providing an exceptional opportunity for new greenfield discoveries.
Province-scale greenfield exploration activities commenced in 2021, with the Company systematically acquiring project-wide geophysical surveys (airborne electromagnetics, ultra-detailed aeromagnetics, Falcon airborne gravity), conducting in-field geological reconnaissance and completing large surface geochemical surveys, primarily targeting magmatic Ni-Cu-Co-PGE sulphide, orogenic Au-Cu and intrusive-related/hydrothermal Au-Cu mineral systems.
The work completed by Chalice to date has highlighted >40 greenfield targets across the Province.
Barrabarra exploration results
A significant outcome of recent regional targeting at ~4,600km[2] Barrabarra Project is a project-wide interpreted geology map which shows extensive areas of unrecognised greenstone belt geology within granite-gneiss basement (Figure 1).
The Company has utilised a proprietary database to better direct its targeting along interpreted crustal scale structures which are a known first-order control on the localisation of ore deposits.
The regional geological setting at Barrabarra is comparable with other greenstone belts in the South West and Youanmi terranes of the Yilgarn which host significant gold and copper deposits, such as Boddington (~40Moz Au) – owned by Newmont Corporation (ASX: NEM).
The region is also transected by prominent first order regional structures and secondary splays which are typically prospective for orogenic gold and/or hydrothermal copper-gold.
The Company has undertaken regional ~1km spaced soil sampling over discrete magnetic anomalies and gravity highs interpreted to be ultramafic-mafic intrusions, and subsequently expanded the search space to screen regional and second order structures and structurally complex greenstone belts with ~1km x 100m spaced soil geochemical lines infilled to ~400m x 100-50m for target definition.
The Project contains abundant lateritic soils which have been the preferred sample media for surface geochemical programs to facilitate low-cost on-ground exploration.
Sampling to date has generated over 11 magmatic Ni-Cu-PGE soil anomalies and two new highpriority gold targets – Recherche West and Warspite.

Recherche West Target
The Recherche West Target is a new ~15km long Au plus Ag-As pathfinder trend, which has been identified on 400m x 100-50m spaced soil sample grid, over a prominent east-west trend of complex aeromagnetic anomalies associated with a poorly exposed greenstone belt succession comprising metasediments, ultramafic-mafic intrusions and intermittent banded iron formation (BIF) (Figure 2).
The gold anomaly is coherent at 5-10ppb Au level with a peak result of 235ppb Au. The gold anomalism is coincident with Ag and As, which are typical pathfinders for orogenic gold mineralisation.
==> picture [483 x 342] intentionally omitted <==
Figure 2. Recherche West interpreted geology, aeromagnetics and Au-in-soil contour anomalies
A program of extensional soil geochemical sampling (400m x 100m) is planned to be undertaken over Recherche West to extend coverage along the eastern and southern parts of the current survey area, which remains open.
An initial ~6,000m AC drill program at Recherche West is expected to commence in Q4 after the cropping season, with drilling designed to test beneath peak soil Au+/-Ag-As anomalism on multi-km spaced lines.
Subject to results, provision will be made for additional drill coverage along this ~15km long target area.
Warspite Target
The Warspite Target is a new ~2km long NNW trending gold anomaly at the 10ppb Au level with a peak of 75ppb Au, which has been identified on 400m x 100m spaced soil sample grid, over areas of the Koolanooka greenstone belt not previously sampled.
ASX:CHN
The Koolanooka greenstone belt consists of metabasalt/gabbro, ultramafic, metasediments and BIF bounded by granite-gneiss basement (Figure 3).
==> picture [483 x 342] intentionally omitted <==
Figure 3. Warspite and Suliven Targets, interpreted geology over aeromagnetics.
An analysis of the entire soil database shows background gold level of ~2ppb, so the Warspite anomaly is highly anomalous at ~5x background. The anomaly is associated with coincident Bi, Te and Pd which are metals commonly associated with hydrothermal alteration.
The anomaly is entirely covered by lateritic soils which appear to be residual and infill sampling is warranted to better define lines for initial AC drill testing.
Gold mineralisation has been intersected in the area in shallow 1990’s RAB drilling by Equinox/BHP to the north of Warspite at the Suliven Prospect. The best result from this program was 8m @ 2.68g/t Au from 32m. Drilling was testing a discrete, smaller scale 10ppb gold-in-soil geochemical anomaly. Gold mineralisation is associated with ~5-10% quartz-carbonate veining in saprolite after metabasalt.
Ground-truthing has identified metabasalt/gabbro subcrop located west of the Warspite anomaly showing that the underlying geology is likely to be a mafic/sediment succession and hence similar geology to that hosting the Sulliven Prospect.
The main magnetic anomalies in the region are associated with BIF which show broad scale folding along NNW trending fold axes. The Warspite anomaly appears to be aligned parallel to the regional axial planar foliation which is potentially a favourable structural setting for orogenic gold mineralisation.
A drone aeromagnetic survey (25m spaced flight lines) was undertaken at Warspite to better understand the prospect scale structural setting. The anomaly appears to be aligned parallel to a magnetic anomaly interpreted as BIF, although the main anomalism is associated with a discrete jog or break at the southern end, which is interpreted as a fault (Figure 4) and a highly prospective structural setting.

Figure 4. Warspite Au-in-soil anomalism over magnetics
Additionally, the gold anomaly appears to have been terminated to the north by an interpreted east-west trending cross-fault, and therefore the localisation of the gold anomaly between intersecting structures further highlights a potentially prospective setting for orogenic gold mineralisation.
A program of infill soil sampling (100m x 50m) is scheduled to be commence over Warspite shortly to better define peak areas of Au plus pathfinder anomalism. An initial ~1,000m AC drill program at Warpsite is expected to commence in Q4 after cropping season, with drilling designed to test beneath peak soil Au-Bi, Te, Pd anomalism on ~400m spaced lines.
Forward plan
AC drill programs are scheduled for Q4 CY24 at Barrabarra after cropping activities, with timing subject to heritage clearance, statutory government approvals and landholder consents. Barrabarra is located mostly over broad-acre farmland and the Company has been very successful with obtaining access to undertake its regional exploration programs.
Exploration across the West Yilgarn is continuing in parallel with the Gonneville Project Pre-Feasibility Study, which is evaluating a staged, high-grade development scenario, with ongoing critical path workstreams including metallurgical testwork, flowsheet development, geo-met domaining and regulatory approvals.
This announcement has been authorised for release by the Disclosure Committee.
