HIGH-PRIORITY DRILL TARGETS FINALISED AT BALERION
PROSPECT AHEAD OF IMMINENT DRILLING
HIGHLIGHTS
• Drilling approval received; contractors secured for rapid mobilisation
• Peak View Prospect renamed to the Balerion Prospect following
advancement to drill-ready targets
• 12-hole targeted drill program finalised at the Balerion Prospect within
the Peak View Project, NSW
• Drill targets defined from integrated multi-element soil geochemistry and
induced polarisation (“IP”) survey results, with gravity and magnetic data
used to further refine targeting and structural interpretation
• Drill program designed to test undrilled targets and extensions to known
high-grade mineralisation
Exultant Mining Limited (ASX: 10X) (“Exultant” or “the Company”) is pleased to announce that it has
received drilling approval from the NSW Resources Regulator and has finalised a targeted 12-hole RC
drill program at the Balerion Prospect, formerly referred to as the Peak View Prospect, within its Peak
View Project in New South Wales.
The program has been finalised following the Company’s recent soil geochemistry program, which
defined a 900m-long coincident Cu-Pb-Zn-Ag-Au soil anomaly, and subsequent geophysical work, which
identified multiple high-priority IP (Fig. 1) and gravity anomalies and materially improved structural
understanding across the prospect.1, 2
Following final target ranking and drillhole design, the Company has renamed the Peak View Prospect
to the Balerion Prospect. The Peak View Project name remains unchanged.
Comment from Executive Chairman, Brett Grosvenor:
“Finalising this drill program is an important step in advancing Balerion toward first-pass drill testing of
targets generated from our recent geochemical and geophysical work.
The holes have been designed to test the strongest and most coherent anomalies defined from the integration
of soil geochemistry and IP, with gravity, magnetic and historical drilling data providing further support in
several areas.
With the drilling approval received, contractors secured and ready to mobilise, we are very close to
commencement of drilling and unlocking the secrets of Balerion. This is exactly what we have been working
towards and this will become a pivotal point for 10X and our shareholders”

NEXT STEPS
Earthworks and drilling contractors have already been secured to prepare access and drill sites, and to
carry out the planned drill program.
With approval now in place, the Company intends to:
• Complete earthworks and drill pad preparation
• Mobilise the drilling contractor to site
• Commence drilling of the priority targets
• Integrate drilling results with the existing geochemical,IP, gravity and magnetic datasets to refine
the broader geological model

PLANNED DRILLHOLES
The Balerion drill program has been designed to test targets generated through the integration of surface
geochemistry and IP geophysics, with gravity and magnetic datasets providing additional support in a
number of areas. The Company notes that this same exploration approach - combining geochemistry
and IP to define drill targets - helped lead to the discovery of the Woodlawn deposit in the 1970s.3
This
reference is provided as regional and methodological context only and is not necessarily indicative of
mineralisation at Balerion.
The location of the planned drillholes are shown in Figure 2 and their respective targets are:
• PVRC_A – Testing a strong coincident chargeability and resistivity high beneath the widest part
(200m) of the Cu-Pb-Zn-Ag-Au soil anomaly
• PVRC_B – Targeting a resistivity low anomaly down-dip of a coincident chargeability-resistivity
high beneath the widest part (200m) of the multi-element soil anomaly
• PVRC_C – Targeting a coincident chargeability-resistivity high beneath the multi-element soil
anomaly (Fig. 2)
• PVRC_D – Targeting a resistivity low anomaly down-dip of a coincident chargeability-resistivity
high beneath the soil anomaly (Fig. 2)
• PVRC_E – Testing a western coincident chargeability-resistivity-gravity high (Fig. 3)
• PVRC_F – Targeting a coincident magnetic low, weak chargeability response and gravity low
anomaly down-dip of PVD001/PVD002
• PVRC_G – Targeting a resistivity low anomaly down-dip of PVD001/PVD002
• PVRC_H – Targeting a resistivity low anomaly down-dip of PVI006 (4.4m @ 342.7g/t Ag, 4% Pb,
1.1% Cu, 0.74g/t Au & 0.84% Zn from 48.7m4
)
• PVRC_I – Targeting a coincident magnetic low, weak chargeability response and gravity low
anomaly down-dip of PVI006
• PVRC_J – Targeting a coincident chargeability-gravity high proximal to the Peak View Thrust Fault
• PVRC_K – Targeting a coincident chargeability-gravity high
• PVRC_L – Targeting a resistivity low anomaly down-dip from high-grade massive sulphides
intersected in PVI008 (0.8m @ 22% Zn, 11.6% Pb, 1.2% Cu, 155g/t Ag, 0.5g/t Au from 152.6m4
)
(Fig. 4)
These holes are designed to test a combination of undrilled anomalies, structurally favourable positions
and down-dip extensions to known mineralisation. Collectively, the program represents the first
systematic drill test of targets generated from the Company’s integrated geochemical and geophysical
datasets.

INTERPRETATION AND TARGETING RATIONALE
The Balerion drill program has been designed to test targets generated from the integration of the
Company’s 900m-long Cu-Pb-Zn-Ag-Au soil anomaly with recently completed IP and gravity surveys,
supported by reprocessed magnetic data and historical drilling. This integrated approach has materially
improved the Company’s understanding of the structural and stratigraphic controls at the prospect and
underpins the ranking of the planned drillholes.
Coincident chargeability-resistivity highs
Several of the highest-priority targets are defined by coincident chargeability highs and resistivity highs
beneath the broadest part of the multi-element soil anomaly. The Company interprets these anomalies
as potential VMS feeder or “pipe” positions within the footwall, where disseminated sulphides
developed within a silicic alteration zone may generate a combined chargeability-high and resistivity-
high response. In a VMS setting, this type of response may be associated with copper-rich sulphides

(Fig. 5); however, the source, geometry and mineral content of the anomalies remain untested and will
require drilling to confirm.
Resistivity-low targets down-dip of known sulphides
A second important target style comprises resistivity-low anomalies located down-dip of, and along the
same prospective horizon as, high-grade massive and semi-massive sulphides previously intersected in
historical drilling, including PVI006 (4.4m @ 342.7g/t Ag, 4.0% Pb, 1.1% Cu, 0.74g/t Au and 0.84% Zn
from 48.7m4
) and PVI008 (0.8m @ 22.0% Zn, 11.6% Pb, 1.21% Cu, 155g/t Ag and 0.50g/t Au from
152.6m4
). The Company considers these resistivity-low anomalies may represent thicker accumulations
of more conductive sulphides directly down-dip of the known massive sulphide intersections.
Importantly, the massive sulphide interval in PVI008 sits outside the mapped resistivity-low anomaly
and therefore does not appear to account for the conductive response. This is considered encouraging,
particularly given the 1.2% Cu intersection in PVI008, as it suggests the targeted resistivity-low zone
may reflect a separate and potentially thicker sulphide accumulation immediately down-dip.
Structural and density targets
Additional targets, including coincident chargeability-gravity anomalies proximal to the Peak View
Thrust, are being tested because they occur within a structurally favourable setting adjacent to the
interpreted southern continuation of the Narongo Fault and at the intersection of transverse structures
considered prospective for sulphide accumulation and/or Fe-rich alteration.
The Company cautions that these interpretations are conceptual only. Drilling is required to determine
whether the anomalies are caused by VMS-related sulphides, alteration, lithological contrasts,
structural effects, or a combination of these factors.

and the coincident chargeability-
resistivity anomaly at the Balerion Prospect. The comparison is illustrative only and drilling is required
to confirm the geological source of the anomaly.

Section 1 Sampling Techniques and Data
Criteria JORC Code Explanation Commentary
Sampling
techniques
• Nature and quality of sampling (e.g. cut
channels, random chips, or specific specialised
industry standard measurement tools
appropriate to the minerals under investigation,
such as down hole gamma sondes, or handheld
XRF instruments, etc). These examples should
not be taken as limiting the broad meaning of
sampling.
• Include reference to measures taken to ensure
sample representivity and the appropriate
calibration of any measurement tools or systems
used.
• Aspects of the determination of mineralisation
that are Material to the Public Report. In cases
where ‘industry standard’ work has been done
this would be relatively simple (e.g. ‘reverse
circulation drilling was used to obtain 1 m
samples from which 3 kg was pulverised to
produce a 30 g charge for fire assay’). In other
cases more explanation may be required, such
as where there is coarse gold that has inherent
sampling problems. Unusual commodities or
mineralisation types (e.g. submarine nodules)
may warrant disclosure of detailed information.
Geophysics
• The geophysical program comprised an induced polarisation (IP) survey
and a ground gravity survey completed over the Peak View Prospect. The
IP survey was designed as a time-domain dipole-dipole survey with 50m
receiver dipole length and 50m transmitter dipole length.
• Survey parameters included up to n=16 levels, signal dependent, with a
2 second cycle (0.125 Hz).
• The planned survey comprised four east-west oriented lines of
approximately 1,550m each, spaced 200m apart, for total planned
coverage of approximately 6.6 line km.
• The gravity survey was designed on a nominal 100m x 100m station grid
over the prospect area, for approximately 136 stations, with provision for
additional 50m infill stations over areas of interest if required.
Rock Chip Sampling
• Rock Chips are broken from outcrop or float using a steel Estwing geological
hammer, the entire sample (nominal 0.5kg) is pulverised to produce a 30g
charge for fire assay (Au-AA23) to analyse for Au and 0.25g is used for multi-
element analysis (ME-MS61), where it uses a four acid digestion to dissolve
nearly all minerals. It’s then measured using a mass spectrometer and
optical emission spectrometer.
• Sample locations are marked using handheld GPS
• Sampling is conducted by Company personnel

• Lithology, alteration and mineralogy are logged in the field and entered into
a spreadsheet by a company geologist
Historic sampling
• Historic sampling includes:
o Stream sediment sampling by multiple explorers (WMC 1971,
Delta Gold 1993).
o Soil sampling campaigns by WMC at Peak View Prospect.
o Drilling by WMC during 1978-82 period (14 holes), Denehurst in
1995-96 (2 holes) and Ironbark Zinc during 2010-2012 (11
holes) at Peak View Prospect with 1,170 samples analysed for
Cu, Pb, Zn, As, Ag. Some of the samples were assayed for Au.
• Analytical methods included AAS and fire assay; however, QAQC
protocols from 1975-1995 are not consistently documented in available
reports.
• Rock chips collected by Peak View Exploration were pulverized to produce
a 25g charge for aqua regia digestion with a MS analytical finish to analyze
for 52 elements (AR25/MS52)
Drilling
Techniques
• Drill type (e.g. core, reverse circulation, open-
hole hammer, rotary air blast, auger, Bangka,
sonic, etc) and details (e.g. core diameter, triple
or standard tube, depth of diamond tails, face-
sampling bit or other type, whether core is
oriented and if so, by what method, etc).
• 27 drill holes completed historically between 1975-2012, comprising:
o WMC 1978 – 1982: 14 diamond drillholes for total of 1,852
metres with an average of 132 m.
o Denehurst 1995-96: 2 diamond drillholes for total of 291 m.
o Ironbark Zinc 2010-2012: 11 diamond drill holes for total of
1,710 m.
• Hole orientations generally –60° toward local grid west.
• Diamond holes were NQ/HQ Size.
• Drilling unit was track mounted.
• Core orientation methods not documented in available reports.

Drill Sample
Recovery
• Method of recording and assessing core and
chip sample recoveries and results assessed.
• Measures taken to maximise sample recovery
and ensure representative nature of the
samples.
• Whether a relationship exists between sample
recovery and grade and whether sample bias
may have occurred due to preferential loss/gain
of fine/coarse material.
• Recovery records are limited or inconsistently reported in historic drilling
programs.
• No systematic recording of core recovery or sample quality documented for
early programs (1975-1995).
• Potential sample bias due to preferential loss in broken ground zones
cannot be assessed from available data.
Logging
• Whether core and chip samples have been
geologically and geotechnically logged to a level
of detail to support appropriate Mineral Resource
estimation, mining studies and metallurgical
studies.
• Whether logging is qualitative or quantitative in
nature. Core (or costean, channel, etc)
photography.
• The total length and percentage of the relevant
intersections logged.
• Historic core has been geologically logged to varying standards depending
on the operator and time period.
• Logging generally qualitative in nature, focusing on lithology, alteration,
and mineralisation.
• Core photography not systematically undertaken in early programs.
• Detailed structural logging limited, though some programs noted shear-
foliation oriented N-S with steep dip.
• Most intersections appear to have been logged, though detail level varies
significantly between operators.
