Promising early-stage gold results in the West Yilgarn

First-pass shallow drilling highlights a new large-scale gold target at the Kings Project and confirms proof-of-concept for gold within the Barrabarra Project

Highlights

  • « First-pass Reverse Circulation (RC) / diamond drilling at the Hardtack Target (~5km SE of Bolgart in WA within the Kings Project) has intersected anomalous gold mineralisation along the regionally significant suture of the South West and Youanmi terranes, including 1m @ 6.6g/t Au :

  • « RC drilling was designed to test ground EM plates prospective for Ni-Cu-PGE mineralisation, and unexpectedly intersected orogenic gold mineralisation.

  • « The target will now be refined with wide-spaced Aircore (AC) drilling along a newly identified ~7km long gold-in-soil anomaly.

  • « First-pass, shallow AC drilling at the ~3,600km[2] Barrabarra Project (~85km E of Geraldton in WA) has intersected prospective greenstone geology and anomalous gold/copper at two greenfield target areas previously mapped as barren granite/gneiss:

  • « Warspite Target (~2km long gold-plus-pathfinder soil anomaly) – significant intersections of gold/copper mineralisation were returned in bedrock (including 8m @ 1.2g/t Au from 20m to EOH ), with several holes ending in mineralisation – a potential association with parallel WNW striking structures, which remain open, will now be investigated.

  • « Curtido Target (>1.5km long gold-plus-pathfinder soil anomaly at the eastern end of the ~15km long Recherche West gold-in-soil trend) – several significant intersections of gold mineralisation were returned in bedrock, which remain open to the south and east .

  • « The Recherche West gold-in-soil trend remains poorly tested elsewhere and is a high priority for further reconnaissance AC drilling.

  • « 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 (~30Moz Au, 1.3Mt Cu) , owned by Newmont Corporation (ASX: NEM).

  • « The results to date are an encouraging indication of fertile belts for orogenic gold or hydrothermal gold-copper mineral systems, in a completely untested part of the Yilgarn Craton .

  • « Additional soil sampling and AC drilling is planned to further define/refine these and additional targets across the West Yilgarn, prior to potential follow-up RC/diamond drilling.

Overview

Chalice Mining Limited (“Chalice” or “the Company”, ASX: CHN) is pleased to report encouraging results from ongoing early-stage gold-copper exploration activities across the West Yilgarn Province (Province) in Western Australia.

Chalice continues to explore its ~8,000km[2] West Yilgarn licence holding, with a focus on discovering large-scale gold-copper mineral deposits, comparable to those found at Boddington (~30Moz Au, 1.3Mt Cu) and Deflector (>1.7Moz Au).

The entire licence holding was effectively unexplored pre-Chalice, providing an exceptional opportunity for new greenfield discoveries within the highly endowed Yilgarn Craton.

Chalice has completed a total of 8,850m of first-pass reconnaissance aircore (AC) drilling at the Barrabarra Project. In addition, ~3,000m of RC/diamond drilling has been completed at the Kings Project.

The results from these drilling and sampling campaigns – including the definition of prospective greenstone geology hosting gold-copper intersections in bedrock – are considered highly encouraging and provide proof-of-concept for Chalice’s systematic exploration strategy across the Province.

Gold-copper focused exploration in the Province remains at an early stage, with targeting for goldcopper systems continuing, drawing upon all available datasets including high-quality airborne magnetics, gravity and EM survey data acquired by Chalice from 2021 to 2023 following the discovery of the tier-1 scale Gonneville PGE-Ni-Cu-Co deposit.

The work aims to progressively reduce and refine the exploration search-space, defining areas through a systematic methodology of remote dataset interrogation, on-ground mapping and regolith classification, soil sampling (using the best possible analytical techniques and detection limits), followed by shallow drilling of priority target areas to test the source of any anomalism defined.

The early-stage, proof-of-concept results demonstrate the overall prospectivity of the Province, and Chalice remains highly leveraged to exploration success in this vastly under-explored region, particularly when compared to more mature regions of Western Australia, including the Eastern Goldfields or Youanmi Terranes.

The work completed by Chalice to date has highlighted >40 untested greenfield targets across the Province which warrant further exploration.

Kings Project

The ~1,600km[2] Kings Project is located ~80km north-east of Perth in WA. The Kings Project includes the ~30km[2] Bolgart JV (E70/5151), where Chalice is earning a 70% interest.

Chalice has completed several years of exploration in the region targeting magmatic Ni-Cu-PGE deposits, however the region has seen very limited systematic exploration for orogenic or intrusion related gold systems.

The newly defined Hardtack Target, ~5km south-east of Bolgart, is centred on 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 (Figure 1).

Figure 1. Hardtack Target RC/diamond drilling and gold-in-soil contours over regional magnetics.

Chalice completed a 13-hole, 2,300m RC/diamond drilling campaign, which targeted a series of MLEM plates with conductance from 300 to 3,000 Siemens. These plates had a N-S orientation, consistent with the regional strike, and were coincident with magnetic and gravity features considered prospective for Ni-Cu-PGE magmatic sulphide mineralisation.

While the drilling successfully defined zones of heavily disseminated to massive iron sulphides (pyrrhotite>pyrite), no significant nickel or copper intercepts were returned.

However, the drilling did define 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. These anomalous results coincide with a newly defined, coherent gold-in-soil anomaly (≥5ppb Au level, >5x background), suggesting that the soil anomalism is related to a bedrock source.

The target area is located ~4km south-east of historical gold workings at the Blackboy Hill mine (c. 1897).

Given the large-scale potential of the new target and the promising indications from wide-spaced drill holes to date, further AC drilling is planned to test the source of the gold anomalism as a priority. Further RC/diamond drilling will be dependent on the results from AC drilling.

Barrabarra Project

The 100% owned, ~3,600km[2] Barrabarra Project is located ~85km east of Geraldton in WA. It is essentially a completely unexplored part of the Yilgarn Craton, with only 37 RC, 405 AC and 26 RAB drill holes across an expansive area (420 of which have now been drilled by Chalice).

Chalice’s exploration to date has identified several thousand square kilometres of greenstone geology, incorrectly mapped previously as barren granite/gneiss terrane (Figure 2).

Warspite Target

The Warspite Target is a ~2km long NNW trending gold anomaly at the 10ppb Au level (~5x background) with a peak of 75ppb Au, which has been identified on a 400m x 100m spaced soil sample grid, over areas of the Koolanooka greenstone belt not previously sampled.

The Koolanooka greenstone belt consists of meta-basalt, gabbro, ultramafic, metasediments and BIF bounded by granite-gneiss basement (Figure 5).

Anomalous gold and copper was intersected in several holes from very shallow depths, with significant results in bedrock including:

  • « 8m @ 1.21g/t Au from 20m to end-of-hole (EOH), incl. 3m @ 2.24g/t Au from 24m (BBAC136);

  • « 1m @ 0.16g/t Au from 22m to EOH (BBAC289).

Orientation of the anomalous results may indicate mineralisation associated with WNW trending structures, which requires further on-ground validation. While the initial shallow results are low-level, they are encouraging given the holes ended in mineralisation. Further on-ground validation work is currently underway and follow-up drilling will be scoped based on this work.

Recherche West Trend

The Recherche West Trend is a ~15km long Au plus Ag-As pathfinder trend, which was originally identified on a 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 6).

==> picture [483 x 342] intentionally omitted <==

Figure 6. Curtido-Tauco Targets AC drilling and gold-in-soil contours over regional magnetics.

The main gold anomaly at the Curtido target, which forms part of the broader Recherche West Trend, is coherent at 5-10ppb Au level (~5-10x background) with a peak result of 235ppb Au. The gold anomalism is coincident with Ag and As, which are typical pathfinders for orogenic gold mineralisation.

Anomalous gold was intersected in several holes, with significant results including:

  • « 4m @ 0.42g/t Au from 32m (BBAC346);

  • « 6m @ 0.40g/t Au from 43m, incl. 1m @ 1.27g/t Au from 43m (BBAC242).

While initial shallow results are low-level, they are encouraging and warrant further work. This is the first ever bedrock gold mineralisation intersected in this area and provides an encouraging proof-ofconcept of prospectivity for gold mineralisation in this newly identified greenstone belt.

Further soil sampling around the Curtido Target area is planned, as well as between the Curtido and adjacent Tauco Target, where low-level gold anomalism was also intersected in the recent AC drilling. Further AC drilling will be dependent on soil sampling demonstrating anomaly footprints of scale.

About the West Yilgarn Province

Chalice’s ~8,000km[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.

==> picture [483 x 349] intentionally omitted <==

Figure 7. Chalice portfolio of exploration projects in the West Yilgarn.

The entire licence holding was effectively unexplored pre-Chalice (owing to the lack of outcropping basement geology and prevalence of large-scale farming activities), 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 orogenic Au-Cu, intrusiverelated/hydrothermal Au-Cu and magmatic Ni-Cu-Co-PGE sulphide mineral systems.

The work completed by Chalice to date has highlighted >40 greenfield targets across the Province.
