MULTIPLE HIGH-PRIORITY DRILL TARGETS
AT PEAK VIEW PROSPECT
HIGHLIGHTS
• IP survey defines four priority target zones, including a strong
undrilled chargeability-resistivity anomaly open to the south
• Untested western chargeability anomaly coincides with a 1.1km
gravity high adjacent to the Peak View Thrust (Fig. 1)
• Magnetic and gravity data highlight transverse structures interpreted
to control mineralisation
• Peak View Thrust interpreted as the southern continuation of the
fertile Narongo Fault, which hosts the Captains Flat VMS deposit and
>30 mineral occurrences along strike
• Maiden drilling campaign to commence in coming weeks
Exultant Mining Limited (ASX: 10X) (“Exultant” or “the Company”) is pleased to report results
from recently completed induced polarisation (“IP”) and ground gravity surveys at the Peak View
Prospect, located within the broader Peak View Project in New South Wales.
Both surveys were designed to test the 900m-long multi-element Cu–Pb–Zn–Ag–Au soil anomaly
previously defined by the Company’s soil sampling program1
. The dipole–dipole IP survey
comprised four east–west oriented lines, each 1.6km in length and spaced 200m apart with 50m
electrode spacing (Fig. 2). The ground gravity survey comprised 136 stations collected on a 100m
x 100m grid.
The newly acquired IP and gravity datasets, together with reprocessed and inverted historic
airborne magnetic-radiometric data, have materially improved the Company’s understanding of
the structural architecture at Peak View and defined multiple high-priority drill targets.
Comment from Executive Chairman, Brett Grosvenor:
“These results represent a major step forward in advancing Peak View toward drilling in the coming
weeks. The geophysical surveys have defined multiple compelling anomalies and, importantly, provide
context for historical drilling results within a broader structural framework.
At a macro scale, this framework is highly comparable to that observed at major VMS deposits such as
Woodlawn and Captains Flat, the latter of which lies along the same geological structure.
We are highly encouraged by the strong coincident chargeability and resistivity response, which defines
a compelling drill target and underpins our confidence in a potential new discovery at Peak View.

PEAK VIEW PROSPECT - GEOPHYSICAL RESULTS
Induced Polarisation Results
The IP survey has defined four significant areas of interest at Peak View:
1. Western chargeability anomaly
A ~700m-long moderate chargeability (>10msec) anomaly with local coincident resistivity highs
has been defined to the west of historical drilling (Fig. 3). This anomaly has never been drill tested
and represents a newly recognised target zone not previously identified by earlier explorers.
Importantly, high-grade mineralisation intersected in historical drilling is associated with a
relatively weak chargeability response (around 8msec), while the stronger, western chargeable
anomaly exceeds 12msec. The anomaly appears to strengthen to the north, where it remains
open.
2. Coincident chargeability and resistivity high beneath main soil anomaly
A strong coincident chargeability high and resistivity high, with values up to 18msec and 4,900Ωm,
respectively, has been identified beneath the widest part of the 900m-long multi-element soil
anomaly. Significantly, this anomaly has never been tested by historical drilling and remains open
to the south. PVI010 was drilled within 40m of the anomaly and returned 1.3m @ 3.4% Zn, 1.4%
Pb, 21g/t Ag & 0.14% Cu from 106.1m3
(Fig. 4).

3. Resistivity low anomaly down-dip of known massive sulphides
A previously untested resistivity low, interpreted as a conductive anomaly, has been identified
down-dip of massive sulphides intersected in historical drilling (Fig. 5). This target provides an
important down-dip follow-up opportunity relative to known high-grade mineralisation.
4. Chargeability anomaly on sediment–granite contact
A discrete chargeability high has been identified on the contact between sediments and granite to
the east. This target represents an additional, previously untested position within the broader
Peak View mineralised system.

Ground Gravity Results
The ground gravity survey has defined a 1.1km-long gravity high anomaly that is spatially
coincident with the western ~700m-long chargeability anomaly (Fig. 1 & 6) and its associated local
resistivity highs. The coincidence of these responses materially upgrades this target corridor and
suggests potential for sulphide accumulation and/or dense alteration within a structurally
favourable setting.
The survey has also defined a ~1km-long gravity low anomaly that appears to coincide with the
area targeted by much of the historical drilling. This contrast highlights that significant parts of the
broader system, including the newly recognised gravity high corridor, remain effectively untested
by earlier exploration.
TECHNICAL DISCUSSION
To provide further context for the IP and gravity results, the Company has reprocessed and
inverted historic airborne magnetic-radiometric data acquired by Denehurst in 19942
. This work
has materially improved structural interpretation across the prospect area and delineated several
NW–SE trending transverse structures that intersect the Peak View Prospect. This structural
architecture is comparable with that recognised at nearby VMS deposits such as Captains Flat and
Woodlawn, where subtle cross-structures are interpreted to play an important role in localising
mineralisation.
At Peak View, these transverse structures appear to be influencing both the geophysical and
geochemical anomaly patterns (Fig. 6). Notably, the multi-element surface geochemical anomaly
broadens markedly where one of these structures intersects the prospect, broadly coincident with
a strong chargeability and resistivity high defined by the IP survey (Fig. 3 & 4). This southern
anomaly is interpreted to lie within the footwall and may reflect an accumulation of disseminated
sulphides within an envelope of silicic alteration, producing the combined chargeability-high and
resistivity-high response. In a VMS setting, this type of response may be consistent with a footwall
feeder zone, which is commonly associated with copper-rich sulphides, although the source of the
anomaly remains untested and will require drilling to confirm.
In addition to the NW–SE transverse structures, a major NNW-striking mapped thrust fault, locally
termed the Peak View Thrust, forms the contact between the Yalmy Group to the east and the
Jerangle Metamorphic Complex to the west. This structure is interpreted to represent the
southern continuation of the Narongo Fault, a major regional mineralising conduit that hosts the
Captains Flat VMS deposit and more than 30 recorded mineral occurrences between Captains Flat
and the Peak View Prospect (Fig. 7), highlighting the apparent fertility of this structural corridor.
Significantly, the 1.1km-long gravity high with coincident IP chargeability is located directly
adjacent to the Peak View Thrust and is intersected by several transverse structures, defining a
compelling untested structural target. The combined chargeability and density response may
reflect either a dense accumulation of disseminated sulphides or disseminated sulphides
developed within an iron-rich alteration system, although the anomaly remains untested.
Importantly, the Company’s surface geochemical sampling did not extend sufficiently west to fully
test the Peak View Thrust corridor.

A third key feature is the low resistivity anomaly identified directly down-dip of, and along the
same prospective horizon as one of the best historical drill intercept at the prospect, PVI006 (4.4m
@ 342.7g/t Ag, 4.0% Pb, 1.1% Cu, 0.74g/t Au and 0.84% Zn from 48.7m3
) (Fig. 5). This anomaly
may indicate a thicker accumulation of more conductive sulphides along the same horizon that
hosts massive sulphide mineralisation intersected in historical drilling. By contrast, the ~1km-long
gravity low appears to coincide with a unit of coarse- to fine-grained rhyolite, suggesting
lithological density contrast may explain at least part of that response. The combination of
favourable structural architecture, strong surface geochemical anomalism and multiple untested
geophysical anomalies materially upgrades the prospectivity of Peak View and supports priority
drill testing.

Appendix A: Peak View JORC Code, 2012 Table
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.
Subsampling
techniques and
sample
preparation
• If core, whether cut or sawn and whether
quarter, half or all core taken.
• If non-core, whether riffled, tube sampled, rotary
split, etc and whether sampled wet or dry.
• For all sample types, the nature, quality and
appropriateness of the sample preparation
technique.
• Quality control procedures adopted for all sub-
sampling stages to maximise representivity of
samples.
• Measures taken to ensure that the sampling is
representative of the insitu material collected,
• Core sampling methods are not consistently documented across all historic
programs.
• RC samples collected at 0.66 m intervals in most programs; Diamond
drilling samples collected at 0.1 m intervals.
• Sample preparation procedures varied between operators and time
periods.
• No documented field duplicate or second-half sampling programs.
• Quality control procedures for sub-sampling are not systematically
documented for early programs.
• Rock Chips are broken from outcrop or float using a steel Estwing geological
hammer, the entire sample (nominal 0.5kg) is pulverised t
