Yandal Resources Ltd (ASX: YRL, “Yandal Resources” or the “Company”) is pleased to report that
all assay results from the large-scale Caladan air-core (AC) drilling program that commenced in
early June have been received (see Tables 2 and 3). Fire assay results from the final 14 AC holes
have been received and reported within this release. The AC program included 136 holes across
ten lines, for a total of 13,933m of drilling, testing the Caladan target area over 6.4km of strike
(See Figure 1). Lines are 800m spaced with two 400m spaced lines along strike to the north and
south of previous drilling completed across the Arrakis Prospect earlier this year.
In addition to the above, RC drilling is now complete across the Arrakis Prospect, with seven RC
holes totalling 1,374m drilled, testing below significant air-core intercepts across the 2.2km extent
of the recently identified mineralised structure (see figures 1 and 2). All samples have been
dispatched to the lab, with results expected throughout October.
The Company is also pleased to report that the first of two heritage surveys across the Arrakis
prospect is complete, clearing 200 metre spaced lines across the full extent of the mineralised
structure. The second heritage survey is scheduled for the end of September.
The Caladan target area, including the Arrakis Prospect (within E 53/1843, E 53/2304, E 53/2192
and E 53/1882), is part of the broader Ironstone Well-Barwidgee Gold Project (see Figure 3),
located 60km south of the Jundee mining complex (ASX: NST), and 18km north of the recent
Siona discovery, within the Yandal Greenstone Belt.
Caladan Air-Core Results Overview
Air-core results from the final 14 holes of the Caladan air-core program have been received. All
results and drilling details are provided in Tables 2 and 3, and are plotted in Figures 1 and 2. The
completed program included 136 air-core holes for 13,933m of drilling, with the average hole
depth of 102m. Air-core drilling was completed across ten 400 metre or 800m spaced lines over
6.4km of the Caladan fold. Significant intercepts from the final 14 air-core holes that include
25IWBAC115-116, 25IWBAC125-132 and 25IWBAC146-149 are listed in Table 3 and are highlighted
in Figure 1.
Results from air-core drilling have demonstrated several mineralised and anomalous gold trends.
The most significant being the interpreted 2.2km long mineralised structure that defines the Arrakis
Prospect, with intercepts including:
o 11m @ 2.1 g/t Au*1 from 90m in 25IWBAC023, including
7m @ 3.1 g/t Au from 92m.
yandalresources.com.au | ASX:YRL
2
o 12m @ 1.1g/t Au*1 from 45m in 25IWBAC032.
o 12m @ 0.5 g/t Au*1 from 70m to EOH in 25IWBAC032.
o 11m @ 1.4 g/t Au*1 from 71m in 25IWBAC044, including
6m @ 2.3 g/t Au from 72m.
o 22m @ 0.5g/t Au*1 from 75m in 25IWBAC099, including
7m @ 1.2 g/t Au from 75m.
o 5m @ 0.7 g/t Au*1 from 112m to EOH in 25IWBAC052.
*1: Previously released air-core drilling results see ASX releases dated 10 July 2025, 31 July 2025 & 18 August 2025.
These significant intercepts occur within a broader envelope defined by gold anomalies within
the air-core drilling that is approximately 200m wide and striking over 3.2km (air-core anomalies
are defined as either a 1m sample >0.1 g/t Au at the bottom-of-hole or 4m @ 0.1 g/t Au or better
within the completely or partially weathered rock within an individual air-core hole).
Partially weathered to weathered mineralisation observed within air-core drilling is associated
with a broad zone of deformation and alteration hosted on the northeast margin of a 500m wide
dolerite sequence (includes basalt, dolerite and gabbro).
Arrakis RC Drilling
A seven-hole RC program including 1,374m of drilling is now complete across the Arrakis Prospect
(see Table 4). The RC drilling program has tested the fresh rock positions below recent air-core
intercepts (Figures 1 and 2) to confirm mineralisation continuity within fresh rock and define the
geometry of the host structures. RC drilling has successfully intercepted broad zones of shearing
and alteration in all holes. This includes a wide range of alteration assemblages and deformation
textures. Further geological observations will be provided once results are received over the next
3-6 weeks.
Heritage Surveys
The first follow-up line clearing survey has been completed across the Arrakis Prospect (see
Figures 1 and 2). This survey sought to clear 200m spaced drill lines across the Arrakis Prospect.
Authorisation to clear the survey lines is expected once the survey report is received in 4-6 weeks.
A second heritage survey is scheduled for late September or October. This survey aims to clear
closer spaced lines (up to 80m spaced) across the Arrakis Prospect and broader Caladan target
area.

Next Steps
Further air-core and RC drilling is scheduled across the Arrakis Prospect and broader Caladan
target area after RC drilling results are received. This will include air-core drilling to the northwest
and southeast of the currently defined Arrakis structure, and infill air-core drilling of parallel
regolith anomalies (see Figure 1) within the Caladan target area. Further RC drilling will focus on
infilling the currently defined extents of the Arrakis Prospect subject to future drilling results.
Looking Ahead
The Company maintains a robust cash position and a very active exploration schedule for
the second half of 2025. Notable near-term activities and news flow include;
1.
Results from RC drilling across the Arrakis prospect are anticipated in the next 3-6 weeks;
2.
A second heritage survey to clear closer spaced lines across the Caladan target area,
including the Arrakis Prospect, is scheduled for late September or October.
3.
First results from AC drilling across the New England Granite target area are anticipated
in the coming weeks.
4.
Completion and settlement of the Gordons Gold Project Tenement Sale Agreement
for a total consideration of A$2.81m in cash and Horizon Minerals (ASX: HRZ) Shares in
the coming months.

ASX Announcement 17 September 2025
Yandal Resources has completed multiple lines of air-core (AC) drilling across the core of the
Caladan target area. The drilling utilised an 85mm air-core blade reaming down to an average
down-hole depth of 103m. Hole depths vary between 41m to 209m. All air-core holes were
drilled to fresh rock or until blade refusal. Holes were drilled at an angle of -60° to the southwest.
Groundwater was often encountered during the process of drilling; in the limited number of
times where excessive water was encountered holes were close to the target depth.
Yandal Resources (YRL) air-core drilling samples were collected via a rig-mounted hydraulically
operated cyclone and splitter. One split was collecte
