Chalice is a globally recognised name in minerals exploration, led by an experienced and proven team. Our major greenfield discovery in early 2020, Gonneville, is on track to become a major new PGM-Ni-Cu-Co mine in ~2030. The transformational discovery defined a new exploration search space, the West Yilgarn Magmatic Province in Western Australia. Chalice secured large exploration licence holdings across the province as first-mover, and has continued to explore systematically since 2021 and enter into new exploration joint ventures in search of new mineral deposits.
The western part of the Yilgarn craton is considered one of the most exciting critical minerals provinces globally, given it is largely unexplored but is considered highly prospective for:
Orthomagmatic Ni-Cu+/-PGM sulphide deposits (i.e. Chalice’s ~17Moz 3E (PGM+Au), ~960kt Ni, 540kt Cu, 96kt Co Gonneville Resource);
Intrusion-related/orogenic gold-copper deposits (i.e. the ~40Moz Boddington gold mine – owned by Newmont Corporation (ASX: NEM)); and
Lithium-Caesium-Tantalum pegmatite deposits (i.e. the ~2.5Mt Li Greenbushes lithium mine – owned by Tianqi Lithium Corporation/IGO Limited JV (ASX: IGO (51%) and Albemarle Corporation (NYSE: ALB) (49%)).
In addition to the potential of the West Yilgarn, Chalice has acquired several other exploration projects across Western Australia, South Australia, the Northern Territory and New Zealand, targeting both Iron-Oxide-Copper-Gold (IOCG) and orogenic gold mineral systems.
Chalice also holds several strategic investments and royalties, including a A$5 million contingent payment due upon the achievement of commercial production at the Nyanzaga Project in Tanzania (owned by Perseus Mining (ASX: PRU), where first production is expected in early CY27.
Chalice Mining Project Portfolio
Western Australia
Goomalling Copper Project (earn-in to 70% + 100% owned)
The Project is located in the central Wheatbelt of WA between the towns of Kauring and Yerecoin.
Soil sampling in early 2026 identified a ~2.5km long, coherent copper-molybdenum-silver soil anomaly at the new Deep Blue Target, ~10km north of Goomalling.
Strong coincident magnetic and gravity anomalies indicate the presence of a large-scale hydrothermal system with skarn-style affinities extending over >2km.
Rock chip sampling identified highly anomalous Cu-REE results dominated by the high-value and highly strategic magnet rare earths Neodymium (Nd), Praseodymium (Pr), Dysprosium (Dy) and Terbium (Tb).
Initial RC drilling at Deep Blue confirmed a mineralised system over 1.2km of strike. High-grade REE rock chips unexplained from first pass drilling – possibly associated with ENE trending structures not yet tested.
Northern Territory
Warrego North Copper-Gold Project (100% owned + earn-in to 70%)
The Warrego North Project is located in the Tennant Creek Mineral Field in the Northern Territory, a highly endowed copper-gold province known for high-grade ironstone-hosted deposits.
Located along strike from the historic Warrego Mine, which produced high-grade copper-gold mineralisation (~6.75Mt @ ~6.6 g/t Au and ~1.9% Cu).
Targeting Tennant Creek-style iron oxide copper-gold (IOCG) mineralisation associated with ironstones.
Prospective geology defined by structural interpretation and coincident magnetic and gravity anomalies.
South Australia
Callabonna Copper-Gold Project (earn-in to 51-65%)
The Callabonna Project comprises two exploration licences located east of Lake Frome in northern South Australia, within a frontier region prospective for iron oxide copper-gold (IOCG) mineralisation.
Earn-in joint venture with Red Metal Limited (EL6204 100% Red Metal; EL6318 51% Red Metal / 49% Variscan Mines).
Located within the broader Gawler Craton, along strike from major IOCG deposits including Olympic Dam and Prominent Hill.
Targeting basement-hosted IOCG mineralisation associated with coincident gravity and magnetic anomalies.
Limited historical drilling has intersected hydrothermal brecciation and alteration indicative of a mineralised system.
Western Australia
Barrabarra Gold-Copper Project (100% owned + earn-in to 80%)
The Barrabarra Gold-Copper Project covers an area of ~3,600km² and is located east of Geraldton, within the highly prospective West Yilgarn Au-Cu and Ni-Cu-PGE Province.
The Project was staked following Chalice’s discovery of the Gonneville Deposit in early 2020.
New geological interpretation has revealed extensive areas of interpreted Archaean greenstone belt geology, transected by prominent regional-scale structures.
Almost entirely unexplored targeting gold-copper systems, such as Boddington (~40Moz Au).
New Zealand
Otago Gold-Antimony Project (100% owned)
The Otago Project comprises ~600km² of prospecting permits across the Otago region of the South Island of New Zealand, within one of the southern hemisphere’s most historically endowed gold provinces.
Targeting orogenic gold-antimony systems analogous to the Macraes deposit (>5Moz Au produced; >10Moz total endowment) and the Bendigo-Ophir district (~2.9Moz Au resource), both hosted within the Otago Schist belt.
Antimony is a designated critical mineral across Australia, the US, the EU and Canada, with supply heavily concentrated in China and Russia, underpinning strong strategic demand for new sources from stable jurisdictions.
Initial rock chip sampling has returned encouraging As-Sb-W pathfinder anomalism along a priority structural corridor, consistent with an oxidised orogenic gold system. A soil sampling programme across the corridor is planned as the next phase of work.
Western Australia
Kings Nickel-Copper-PGM Project (100% owned + earn-in to 75%)
The Kings Project covers an area of ~1,600km² and is located north-east of Perth, in the highly prospective West Yilgarn Ni-Cu-PGE Province.
The Kings Project was staked following Chalice’s discovery of the Gonneville Deposit in early 2020.
Hardtack target is a new ~7km x 700m, north-south trending gold-in-soil anomaly, positioned on the regionally significant suture zone between the South West and Youanmi terranes.
Drilling defined widespread gold anomalism in all holes, including 1m @ 6.61g/t Au from 128m in drill hole BRC002, as well as broader zones of sub-1g/t Au.
Western Australia
Julimar Nickel-Copper-PGM Project (100% owned)
The Julimar Exploration Project covers an area of ~350km² and is located north-east of Perth, within the highly prospective West Yilgarn Ni-Cu-PGE Province.
The Project is an exploration licence holding surrounding the major critical minerals discovery – the Gonneville PGM-Nickel-Copper-Cobalt Project – and includes areas of farmland and State Forest.
The Project is centred on the >30km long Julimar Complex, a newly recognised intrusive geological belt that is prospective for magmatic sulphide mineralisation.
Several encouraging zones of sulphide mineralisation have been intersected over ~10km of Julimar Complex strike length to date.
Western Australia
Voyager Gold Project (100% owned)
The Voyager Project comprises a large landholding within the South West Yilgarn, an emerging gold province considered prospective for large-scale gold mineralisation.
Targeting structurally controlled gold systems associated with regional-scale shear zones, including the Yandina and Narembeen shear corridors.
The region hosts several emerging gold deposits, including Katanning (~3Moz), Tampia (~700koz) and Griffins Find (~90koz), demonstrating the potential for significant gold systems.
Exploration is focused on identifying large-scale, underexplored structural corridors beneath shallow cover, where historical datasets are limited.
