Yandal Resources Limited
Chairmans report
30 June 2025
Dear Yandal Shareholders,
As I reflect on the financial year 2025, I am pleased to recount several significant developments and express our
gratitude to those who have contributed to our progress.
As I commented last year, our commitment to technically focused and systematic exploration has yielded
impressive results and set a strong foundation for our future programs. Our strategy of deliberately exploring for
significant discoveries has seen material success at Siona within New England Granite and the emerging Arrakis
prospect within the Caladan target area; together with Flushing Meadows these now form the core focus of your
Company. These exploration successes are a credit to all associated with Yandal and highlight the quality work
your Company is undertaking.
In financial year 2025, we completed some 12,500 metres of air core drilling, 13,500 metres of reverse circulation
drilling and circa 2,400 metres of diamond drilling, with more underway or yet to come. These drilling programs
have, and continue to, significantly advance exploration, generating new gold discoveries and multiple
structural targets that require further work and drilling programs.
To our team, your hard work has been instrumental in driving our exploration forward. Your perseverance and
commitment to technical excellence, safety, and the well-being of one another in every facet of your roles are
very much appreciated by your Board. Under Managing Director Chris Oorschot, our exploration teams have
flourished and rewarded our faith in their expertise and commitment to the strategy. These continued high
standards enable us to realise our goals, remain safe without harm, and reflect the values of your Company of
integrity, commitment and pride.
Importantly, we consider that during this financial year, Yandal has further strengthened our relationship with the
Kultju people, who are the Traditional Owners of the lands in which we work, and I acknowledge and thank them
for their assistance and support in our activities.
I would like to take this opportunity to thank Mr. Tim Kennedy, who stepped down from the Board in May of this
year. Tim was a long-serving Board and Executive team member. He has been a key driver in the strategic
direction of the Company, and on behalf of the Board and team at Yandal, I thank Mr. Kennedy for his
dedicated service and work for your Company.
Finally, our valued shareholders, your ongoing support and confidence in our strategy and work programs are
very much appreciated. We are committed to delivering shareholder value and maintaining the highest
standards of transparency and accountability, together with ensuring shareholder funds are allocated optimally
to progress our exploration strategy.
I take this opportunity to thank my colleagues on the Board, together with our Company Secretary, Mr. Greg
Fitzgerald, and specialist advisor, Mr. Ed Eshuys, for their dedicated service and guidance to our staff and
Company.
Yandal remains focused on developing our suite of assets within the prospective Yandal belt and now have a
very positive outlook as to the prospectivity of the work we have completed in FY25. The exploration activity of
this year will drive our endeavours into next year as we work to grow shareholder value through exploration
success.
I look forward to sharing with you further as we continue to build on our achievements to date.
Kind regards,
Gregory Evans
Chair, Board of Directors

Review of operations
The loss for the Company after providing for income tax amounted to $8,208,150 (30 June 2024: $5,247,117).
The following is a summary of the activities of the Company for the period ended 30 June 2025. It is recommended
that this Annual Report be read in conjunction with any public announcements made by the Company during the
period.
In accordance with the continuous disclosure requirements, readers are referred to the announcements lodged
with the Australian Securities Exchange regarding the activities of the Company.
REVIEW OF OPERATIONS
Yandal Resources maintains a portfolio of gold exploration projects in the highly prospective Yandal and
Norseman-Wiluna Greenstone Belts of Western Australia (Figure 1). Over the last twelve months, exploration has
focused primarily on early-stage, large-scale target areas within the Ironstone Well-Barwidgee (IWB) Gold Project,
with minor activities also completed across the Mt. McClure and Gordons Gold Projects. The Company has
remained focused on its strategy of identifying and testing early-stage but large-scale gold targets.
Exploration activities increased significantly during the year following the Siona gold discovery, hosted within the
New England Granite, in October 2024. This was followed by the identification of mineralised structure within the
Caladan target area in January 2025, defining the Arrakis Prospect. Both target areas have been prioritised within
the exploration schedule and have seen rapid progress during the year.
A strategic review of non-core exploration assets, including the Gordons Gold Project and Mt McClure Gold Project,
was completed in early 2025. After the end of June, a Tenement Sale Agreement was executed with Horizon
Minerals Ltd (ASX: HRZ) for the sale of the Gordons Gold Project, for a total consideration of $2.81 million in cash
and HRZ shares.

IRONSTONE WELL-BARWIDGEE GOLD PROJECT
The 100% owned IWB Gold Project covers approximately 401km² of highly prospective and under-explored tenure
located between the Jundee and Bronzewing mines in the northern Yandal Greenstone Belt of Western Australia
(Figure 2).
Yandal has an established Mineral Resource of 268,000oz of gold at Flushing Meadows and considers there to be
strong potential to make new, large-scale discoveries within its extensive tenement holding. (Refer to the ASX
announcement of 4 November 2020 for details of the Flushing Meadows Resource).
The project area encompasses several large-scale geological settings, where analysis completed by the YRL
exploration team has identified new conceptual targets that have significant discovery potential, including the
New England Granite (NEG), Caladan, and Irulan target areas (See Figure 2). The IWB Project also includes several
advanced prospects, where limited historic and YRL drilling has returned robust gold intercepts, indicating the
potential for large-scale discoveries. Both the early-stage and more advanced prospects are the focus of ongoing
exploration.
During the year, exploration across these target areas has resulted in several significant exploration successes,
including the Siona discovery hosted within the New England Granite, and the delineation of a more than 2.2km
long mineralised structure within the core of the Caladan target area, designated the Arrakis Prospect. These results
demonstrate a maturing exploration strategy that aims to uncover significant new discoveries in the under-explored
Yandal Greenstone Belt.

Yandal Resources Limited
Directors' report
30 June 2025
Caladan Target Area
In June 2024, a series of new high-priority targets were identified based on detailed gravity data collected by
Yandal and a comprehensive analysis of open file data. Most notable was the identification of the Irulan and
Caladan target areas, which show broad similarities to several world-class gold camps (see ASX Release 11th of
June 2024):
●
The interpreted Caladan Fold displays similarities to the broader structural setting of the Boomerang Anticline
that hosts the Golden Mile Deposit and the folded mafic sequence of the Timmins-Porcupine gold district in
Canada.
●
The interpreted Irulan Dolerite Complex resembles the litho-structural setting of the Jundee deposits but on a
smaller scale.
Across the Caladan and Irulan Targets, several low-level in-situ saprolite anomalies were identified within shallow
historical drilling, including a continuous 3km long northwest striking anomaly within the core of the interpreted
Caladan Fold designated CAL-01 (now the Arrakis Prospect). Significantly, this broad-spaced drilling was shallow
and only tested upper saprolite clays, a portion of the regolith profile prone to gold depletion across the Yandal
Greenstone Belt. This underscored the attractive interpreted structural setting and untested nature of this large
target area, emphasising the need for more effective exploration.
A single line of air-core drilling commenced in October across the core of the Caladan target area, testing the
central part of the CAL-01 anomaly.
2024 Caladan AC Results
Results from the Caladan AC drilling program in early January (see ASX release dated 15 January 2025) relating to
the 2024 AC drilling program across the Caladan target area included seventeen holes for 1,688m of drilling,
variably spaced (80m to 200m) along a single northeast-trending (towards 045°) drilling line. Results from the 2024
AC drilling program across the Caladan fold returned a cluster of significant intercepts, all within or proximal to the
in-situ regolith Au anomaly CAL-01 (See Figure3), including:
●
11m @ 1.7 g/t Au from 97m to end-of-hole in 24IWBAC063, including
●
3m @ 3.5 g/t Au from 102m
●
2m @ 1.2 g/t Au from 74m in 24IWBAC013
●
4m @ 0.5 g/t Au from 88m in 24IWBAC016
●
3m @ 0.2 g/t Au from 81m in 24IWBAC015
The significant intercept in 24IWBAC0063 is located on the northeast margin of the CAL-01 regolith anomaly. This
result, combined with the adjacent intercepts, demonstrates a potential correlation between the shallow CAL-01
regolith Au anomaly and a primary mineralisation source. The new prospect was subsequently named Arrakis.
The 11m @ 1.7g/t intercept within 24IWBAC063 is hosted within an interpreted sheared dolerite, displaying strong
sericite alteration, up to 3% veining and 5-10% fine disseminated sulphides as a combination of both pyrite and
arsenopyrite. The Arrakis Prospect is overlain by 10-14m of transported cover.
In addition to the significant intercept, the air-core drilling also confirmed gravity highs to coincide with fractionated
dolerites, separated by a sequence dominated by variably altered intermediate (andesite) volcaniclastics and
sediments.

Defining the Arrakis Prospect
In April 2025, assay results from a small RC drilling program across the Arrakis Prospect within the Caladan target
area were reported. Four RC holes (700m total) were drilled along the single line that transects the core of the
Caladan Fold (see Figures 4 and 5). Significant intercepts included:
●
11m @ 0.5 g/t Au from 168m in 25AKSL003
- Including 3m @ 1.2 g/t Au from 174m
●
5m @ 1.3 g/t Au from 243m in 25IWBRC0037*1
- Including 2m @ 2.7 g/t Au from 246m
*1 RC hole 25IWBRC0037 only partially tested the targeted shear zone.
Several new structures were also identified in the depleted upper regolith, including:
●
9m @ 0.4 g/t Au from 54m in 25IWBRC0037
- Including 1m @ 1.8 g/t Au from 61m
●
8m @ 0.4g/t Au from 105m in 25IWBRC0037
The deeper RC drilling results demonstrated early evidence of mineralisation continuity into fresh rock and a subvertical geometry. Results also highlight the potential for multiple mineralised structures within the interpreted mafic
host. These results paved the way for the larger-scale air-core program across the Caladan target area that
commenced in June.
2025 Caladan Air-Core Drilling
In early June, the large-scale Caladan AC program commenced. The program saw drilling completed across ten
lines, with a total of 132 holes for 13,458m of drilling completed after June 30. The aircore program tested a
significant expanse of the Caladan target area, including 6.4km of strike (See Figure 6).
Results from the air-core drilling reported post-June 30 (see ASX releases dated 10 July 2025, 31 July 2025 & 18 August
2025) delivered numerous significant intercepts including :
●
11m @ 2.1 g/t Au from 90m in 25IWBAC023, including
- 7m @ 3.1 g/t Au from 92m.
●
12m @ 1.1g/t Au from 45m in 25IWBAC032.
●
12m @ 0.5 g/t Au from 70m to EOH in 25IWBAC032.
●
11m @ 1.4 g/t Au from 71m in 25IWBAC044, including
- 6m @ 2.3 g/t Au from 72m.
●
22m @ 0.5g/t Au from 75m in 25IWBAC099, including
- 7m @ 1.2 g/t Au from 75m.
●
5m @ 0.7 g/t Au from 112m to EOH in 25IWBAC052.
These results demonstrate that the mineralised structure intercepted in AC drilling completed in late 2024 (see ASX
release 15 January 2025 & Figure 3) is potentially continuous along more than 2,200m of strike and remains open
to the northwest and southeast, see Figure 6. Across all intercepts, mineralisation is hosted within sheared and
altered dolerite.
The Arrakis Prospect
The Arrakis prospect hosted within the core of the Caladan target area represents a significant discovery
opportunity. Heading into the 2025/26 financial year, Yandal Resources aims to advance the Prospect further with
further RC drilling and infill air-core drilling.

Irulan Target Area
A 52-hole ~3,300m air-core program was completed across the northern half of the Irulan target area in late 2024,
and results were received in early 2025. Results demonstrate several anomalies and trends within the upper regolith
profile (see Figure 4). The average drill hole depth was 63m across the program, and the base-of-transported cover
varied between 2m and 12m. The depth of weathering shallowed towards the southeast.
Results include several low-level gold anomalies from the upper regolith profile. Recent drilling across the Arrakis
Prospect demonstrates the potential of depletion within the upper part of the regolith profile and the need to
investigate even low-level regolith anomalies and mineralisation.
The weathering profile across the southern half of the Irulan target (including the Rosewall Prospect) is shallow. Aircore drilling is unlikely to provide a sufficient test within this eroded regolith setting. RC drilling will be scheduled to
test this portion of the Irulan target in late 2025 or early 2026.
New England Granite
The NEG target area comprises a 4.2km long, 2km wide granitoid, covered by 6-20m of transported cover and
exhibits strong regolith gold anomalism in shallow historical drilling proximal to the intrusive contact (Figure 2 and
Figure 7).
RC drilling targeting structures observed in two 400m deep diamond holes, 24YRLEIS0001 and 24YRLEIS0002, resulted
in the Siona discovery in October 2024. After this discovery, several additional structural settings across the NEG
have been identified as significant targets for future exploration (See ASX release dated 21 May 2025).
Siona Discovery
Following the completion of the updated targeting model at NEG, an RC program comprising 2,400m of drilling for
twelve holes designed to test structural targets proximal to the eastern intrusive margin was initiated. Two holes,
24IWBRC0039 and 24IWBRC0044, intercepted significant mineralisation and defined an emerging gold discovery
named the Siona Prospect. These results were reported to the ASX on 21 October 2024.
Follow-up RC drilling commenced across Siona in early November, and by late December, fourteen holes for
2,900m had been completed, testing the main northwest striking Siona trend (see ASX release dated 25 November
2024). This drilling highlighted mineralisation continuity over more than 450m along strike and demonstrated a range
of mineralisation styles with intercepts including:
●
107*2 @ 1.0 g/t Au from 96m to end-of-hole in 24IWBRC0039 (ETW of 30-40m)
- Original intercept extended from 78m @ 1.2g/t after re-entry
●
80m*2 @ 1.0g/t Au from 67m in 24IWBRC0047(ETW of 30-40m)
●
17m*2 @ 4.9g/t Au from 85m in 24IWBRC0050 (ETW of 8-10m)
●
14m*2 @ 1.8/t Au from 63m in 24IWBRC0044 (ETW of 10-12m)
●
35m*2 @ 1.0g/t Au from 122m in 24IWBRC0046 (ETW of 28-32m)
●

Yandal Resources Limited
Directors' report
30 June 2025
Siona Diamond Drilling
Four new diamond holes and two diamond tails were drilled across Siona (see Figure 3), with significant results
including:
●
16.3m @ 0.5 g/t Au from 322.2m in 25IWBRD0003
●
29.1m @ 0.4g/t Au from 282.9m in 25IWBRD0010
●
6.4m @ 1.5 g/t Au from 103.5m in 25IWBDD0009, including
- 0.3m @ 3.6g/t Au from 105.8m
- 0.4m @ 12.7g/t Au from 108.3m
- 0.4m @ 6.2g/t Au from 109.5m
The diamond drilling results confirmed wide, low-grade gold mineralisation continuity at depth. Geological analysis
suggests continuous higher-grade mineralisation occurs within the broader low-grade mineralisation, with the
plunge direction controlled through the interaction of the deformed intrusive margin and oblique cross-cutting
shear zones.
Refining Structural Targets
The completion of diamond drilling has allowed a detailed set of geological observations to be made and
analysed. The most significant observation made by Yandal Resources is that mineralisation develops wherever
deformation occurs, both proximal and distal to the host intrusive margin. This observation has been reinforced by
the recently completed RC exploration drilling program at the Salusa Prospect on the southeast corner of the New
England Granite (see ASX release 15 April 2025), including:
●
2m @ 9.4g/t Au from 33m in 25IWBRC0019, and
●
14m @ 0.8g/t Au from 82m in 25IWBRC0019
The geological observations highlights the suitability of the granodiorite in acting as a host for gold mineralisation.
It allows the development of a simple set of targeting criteria to prioritise structural targets derived from geophysics.
With the receipt of all diamond drilling results, the targeting criteria for the New England Granite have been revised
to include:
●
Targeting structures that interact with the intrusive margin with observable offsets (lateral or vertical);
●
Prioritise northwest-trending features and northeast-striking conjugate structures of a similar relative age within
the intrusive away from the intrusive margin;
●
Prioritise structures that are oblique to the granodiorite margin.
In addition to the above, the concept of gold mineralisation occurring deep into the intrusive away from the
