New Gold Discovery Confirmed with Further Drilling Assays
Final assays from the Mascotte drilling program, Mt Carrington, deliver gold up to 9.7g/t Au and
broad mineralisation, confirming a new gold-silver system outside the current Mineral Resource
High Grade and Broad Intercepts
• Final assays have been received from all diamond-cored holes in the maiden eight-hole diamond
drilling program at the Mascotte Prospect (1,841m across holes MSDD001 to MSDD008).
• Gold intercepts confirm continuity of the discovery announced in the first hole:
o 40m @ 1.0g/t Au from 151m, including 9m @ 2.7g/t Au (first hole, MSDD001)i
.
o 57m at 0.3g/t Au from 81m (uncut), including 8m @ 1.3g/t Au from 129m including,
o 1m @ 8.1g/t Au from 131m (MSDD002),
o 1m @ 9.7g/t Au from 167m, including (MSDD007).
• 1m @ 18.7% Pb, 8.7% Zn and 43g/t Ag (MSDD003) confirm the potential for high-grade base-
metal and silver mineralisation.
Discovery Open at Depth and Along Strike
• Results confirm a coherent gold-silver epithermal mineralised system over the 1.3km Mascotte
trend that remains open along strike to the northeast and southwest, and at depth.
Results sit outside the existing 1.2Moz AuEq (115Moz AgEq) Mineral Resourceii
• All drill holes are outside the current Mt Carrington Mineral Resource and provide an opportunity
to increase the existing Mineral Resource with a new discovery.
Ongoing Drilling Planned
• Emu: drilling preparations are underway at the Emu Prospect to target copper-gold mineralisation
near the largest historical producing copper mine in the Mt Carrington district.
• Mascotte: ground geophysics and the planning of follow-up drilling to target the higher-grade gold
and base-metal/silver zones identified across the campaign.

Legacy Minerals Holdings Limited (ASX: LGM, “LGM”, “the Company” or “Legacy Minerals”) is pleased
to provide the results of its completed maiden diamond drilling campaign at the Mascotte Prospect,
part of the Mt Carrington Project in NSW (EL6273, EL9616, EL9727, ALA75).
Management Comment Legacy Minerals CEO & Managing Director, Christopher Byrne, said:
"The receipt of final assays from our maiden diamond drilling at Mascotte has confirmed what the first
hole suggested, which is that we have made a new gold-silver discovery. The implications are
significant as these results show a coherent epithermal system extending over the 1.3km Mascotte
trend and sitting entirely outside the existing 1.2Moz AuEq (115Moz AgEq) Mineral Resource Estimate
at Mt Carringtonii
.
The breadth and grade of these results are highly encouraging. Further gold intercepts, including 3
metres at 3.3g/t gold (with 1 metre at 9.7g/t) in MSDD007 and 8 metres at 1.3g/t gold in MSDD002,
together with a high-grade lead-zinc-silver breccia in MSDD003, demonstrate both the gold and
polymetallic potential of this system. Because every hole lies outside the current Resource Estimate,
these results present a clear opportunity to increase the Mineral Resource estimation.
Importantly, the mineralisation remains open along strike and at depth. With all assays now received,
we are advancing ground geophysics and planning follow-up drilling at Mascotte to target the higher-
grade gold and base-metal/silver zones these results have defined. Drilling is now occurring at the Emu
Prospect for copper-gold near the district's largest historical copper producer. It is an exciting period
of activity ahead for the Company across the Mt Carrington Project."

Mascotte Campaign Overview
The maiden program comprised eight diamond drill holes (MSDD001–MSDD008) for 1,840.95m,
drilled to test the potential for epithermal gold-silver mineralisation beneath and along the 1.3km line
of historical Mascotte workings. All holes intersected variably thick zones of very fine-grained sulphide
mineralisation hosted within veins and breccias in association with hematite and sericite/adularia
alteration, consistent with the style of mineralisation observed at the Mt Carrington epithermal
deposits 5km to the north.
The first hole, MSDD001, reported on 19 March 2026 returned the broadest gold zone of the campaign
(40m at 1.0g/t Au from 151m, including 9m at 2.7g/t Au). Assays have now been received for the
remaining seven holesi

Drill Hole Summaries
MSDD002 confirmed continuity of gold mineralisation west of MSDD001, returning 8m at 1.3g/t Au
from 129m (including 1m at 8.1g/t Au), with additional narrower gold intervals up-hole. MSDD007,
drilled along the trend, returned the highest-grade gold of the campaign at 3m at 3.3g/t Au from 167m,
including 1m at 9.7g/t Au.
MSDD003 intersected a high-grade, base-metal and silver breccia of 2m at 9.4% Pb, 4.7% Zn and
22.8g/t Ag from 180m (including 1m at 18.7% Pb, 8.7% Zn and 43g/t Ag), consistent with the semi-
massive galena-sphalerite breccia logged in core. MSDD006 and MSDD008 returned broader, lower-
grade zinc-lead-silver zones (including 6m at 0.8% Zn in MSDD008), extending the mineralised
footprint to the west and south.
MSDD004, which was a shallower 100m hole targeting a potential parallel vein trend, and MSDD005
returned only minor, narrow mineralisation. Full results for all holes are tabulated in Appendix 2.
Prospect Overview
The Mascotte Prospect is defined by an area of significant historical workings extending over
approximately 1.3km of strike, with several potential parallel mineralised structures historically mined
for silver and gold, with elevated copper and zinc noted in surface sampling and drilling. Historical
drilling intersected strongly elevated silver, with a best historical intersection of 18.3m at 237g/t Ag,
including 9.1m at 394g/t Ag from 3m (PDMS005A)3F
iv
. The completed campaign confirms that the
system is gold-bearing at depth, while the high-grade lead-zinc-silver mineralisation in MSDD003
supports the presence of silver-rich, polymetallic structures adjacent to the gold zones.
The prospect lies adjacent to an increased-conductivity lineament identified in Mobile-MT data, of
similar character to features at the White Rock, Mt Carrington and the Silver King trend, supporting
the interpretation of a major hydrothermal fluid pathway and the potential scale and depth extent of
mineralisation.

Next Steps
With the maiden campaign completed and all assays received, the Company will integrate the results
with geological, geochemical and geophysical data to refine future drill targeting. Planned activities
include ground geophysics over the Mascotte trend and planning of a follow-up drill program focused
on the higher-grade gold and base-metal and silver zones identified, together with continued
advancement of approvals and site preparation across the broader Mt Carrington, White Rock and
Emu prospects.

Appendix 3 – JORC Code (2012) Table 1
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.
Core size analysed was HQ core (diameter:
63.5mm) to end of hole (EOH). LGM used a
reputable drilling contractor, Tier 1 Drilling,
with a suitable rig. Diamond drill core provides
a high-quality sample that is logged for
lithological, structural, geotechnical, and other
attributes. Sub-sampling of the core is carried
out as per industry best practice.
Sampling Techniques Include reference to measures taken to ensure
sample representivity and the appropriate
calibration of any measurement tools or
systems used.
Downhole surveys of dip and azimuth are
conducted using a single shot camera every
30m, and using a downhole Gyro when
required, to detect deviations of the hole from
the planned dip and azimuth. The drill‐hole
collar locations are recorded using a hand‐held
GPS, which has an accuracy of +/‐ 5m. All drill‐
hole collars may be surveyed to a greater
degree of accuracy using a certified surveyor at
a later date. An Olympus Vanta pXRF is used to
spot analyse the drill core onsite. Readings are
taken to help identify minerals and alteration
with field calibration of the pXRF instrument
using standards periodically performed. The
handheld pXRF results are only used for
preliminary assessment of element
compositions, prior to the receipt of assay
results from the certified laboratory. The drill
core was orientated using suitable core
orientation tool by the drilling contractor with
LGM staff supervision. These orientations are
extended onto the remainder of the core and
meter marks for logging. The visible structural
features (veins, bedding, foliation, faults) are
measured against the core orientation marks.
The drill core was cut in half, and assayed at a
certified assay laboratory, ALS Laboratories.
Core is prepared for analysis by cutting along
the longitudinal line and then samples are
numbered as per the pre-designed cut-sheet.
The core is selectively sampled down the drill
string at 1m nominal intervals across the
mineralised zones, unless selected geological or
mineralisation boundaries. A certified sample
standard is inserted a minimum 1:50 samples.
Standards may also be added according to
geology. Where core was incompetent due to
being transported cover or weathered rock,
representative samples were collected along
the axis of the core.
Sampling Techniques 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
Drill sampling: The drill core was cut by LGM
staff. Samples were transported to ALS
Laboratory in Brisbane for assaying. Samples
are crushed to 6mm and then pulverized to
85% passing 75 microns. A 50g split of the
sample was fire assayed for gold. The lower
detection limit for gold is 0.002 ppm, which is
believed to be an appropriate detection level.
All other elements including copper and base
metals (total 48 element suite) are analysed

may warrant disclosure of detailed information.
using a 4-acid acid digest and an ICP finish (ALS
code: ME-MS61 + Au-AA21). Assay standards,
blanks and duplicates were analysed as part of
the standard laboratory analytical procedures.
Company standards were also introduced into
the sampling stream at a ratio minimum of 1
standard for every 50 samples. Sample length:
Core is sampled in 0.2m to 2m sample interval
lengths except for minor changes due to
geological or mineralisation boundaries. Pulps
are retained by LGM for potential follow-up
analysis.
Drilling techniques Drill type (e.g., core, reverse circulation, open‐
hole hammer, rotary air blast, auger, Bangka,
sonic, etc) and details (e.g., core diametre,
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).
Diamond drilling using industry standard
techniques. PQ core (diameter: 85mm) to fresh
rock followed by HQ core (diameter: 63.5mm)
to end of hole (EOH).
Drill sample recovery Method of recording and assessing core and
chip sample recoveries and results assessed.
Core is measured and marked after each drill
run using wooden blocks calibrating depth.
Adjusting rig procedures as necessary including,
drilling rate, run length and fluid pressure to
maintain sample integrity.
Drill sample recovery Measures taken to maximise sample recovery
and ensure representative nature of the
samples.
Core is measured and marked after each drill
run using wooden blocks calibrating depth.
Drill sample recovery 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.
To date, no sample recovery issues have been
identified that would impact on potential
sample bias.
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.
Systematic geological and geotechnical logging
was undertaken. Data collection where
appropriate includes; Nature and extent of
lithologies; Relationship between lithologies:
Amount and mode of occurrence of ore
minerals; Location, extent and nature of
structures such as bedding, cleavage, veins,
faults etc. Structural data (alpha & beta) are
recorded for orientated core; Geotechnical data
is collected as required including recovery,
RQD, fracture frequency, qualitative IRS,
microfractures, veinlets and number of defect
sets. For some geotechnical holes the
orientation, nature of defects and defect fill
may be recorded; Representative bulk density
by Archimedes principle may be taken;
Magnetic susceptibility recorded at 1m
intervals for some holes as an orientation and
alteration characterisation tool.
Logging Whether logging is qualitative or quantitative in
nature. Core (or costean, channel, etc)
photography.
Logging records lithology, mineralogy,
mineralisation, veins, structures, weathering,
colour and other noticeable features. This is
generally qualitative except for % of sulphides
and vein mineral content. Core trays are
photographed in wet form.
Logging The total length and percentage of the relevant
intersections logged.
All drill holes are geologically logged in full.
Sub‐sampling
techniques and
sample preparation
If core, whether cut or sawn and whether

Core is being cut using a conventional
automatic core saw with core holding support.
All samples are collected from the same side of

procedure meets industry standards where
approximately 50% of the total sample taken
from the diamond core is submitted. All
mineralised intervals and surrounding wall rock
were submitted for assay. Sample weights are
recorded by the lab. Samples are delivered by
Legacy Minerals Holdings personnel to ALS
Minerals Laboratory, Brisbane, QLD. Sample
preparation will comprise of an industry
standard of drying, jaw crushing and pulverising
to -75 microns (85% passing) (ALS code PUL-
23). Pulverisers are washed with QAQC tests
undertaken (PUL-QC). Samples are dried,
crushed and pulverized to produce a
homogenous representative sub‐sample for
analysis.
Sub‐sampling
techniques and
sample preparation
Quality control procedures adopted for all
subsampling stages to maximise representivity
of samples.
Quality control procedures include submission
of Certified Reference Materials (standards)
and duplicates with each sample batch. QAQC
results are routinely reviewed to identify and
resolve any issues. All sub-sampling of the
prepared core is completed by the laboratory.
No sub-sampling is completed by LGM.
Sub‐sampling
techniques and
sample preparation
Measures taken to ensure that the sampling is
representative of the in-situ material collected,
including for instance results for field
duplicate/second‐half sampling.
The remaining half-core is stored and allows
assay values to be viewed against the geology;
and, where required, further samples may be
submitted for quality assurance. Quarter core
resampling may be completed in zones where
appropriate.
Sub‐sampling
techniques and
sample preparation
Whether sample sizes are appropriate to the
grain size of the material being sampled.
The sample sizes are appropriate to correctly
represent the mineralization based on style of
mineralisation.
Quality of assay data
and laboratory tests
The nature, quality and appropriateness of the
assaying and laboratory procedures used and
whether the technique is considered partial or
total.
All samples were analysed by ALS Global.
Samples were crushed to 6mm and then
pulverized to 85% passing 75 microns. Gold is
determined using a 50g charge. The resultant
prill is dissolved in aqua regia with gold
determined by flame AAS. The lower detection
limit for gold is 0.002 ppm, which is believed to
be an appropriate detection level. All other
elements are analysed using a 4-acid acid digest
and an ICP finish (ALS code: ME-MS61 + Au-
AA22).
Quality of assay data
and laboratory tests
For geophysical tools, spectrometres, handheld
XRF instruments, etc, the parametres used in
determining the analysis including instrument
make and model, reading times, calibrations
factors applied and their derivation, etc.
No geophysical tools were used to determine
any reported element concentrations.
Quality of assay data
and laboratory tests
Nature of quality control procedures adopted
(e.g., standards, blanks, duplicates, external
laboratory checks) and whether acceptable
levels of accuracy (i.e., lack of bias) and
precision have been established.
Laboratory QAQC involves the use of internal
lab standards using certified reference material
(CRMs), blanks and pulp duplicates as part of
in‐house procedures. The Company also
submits a suite of CRMs and blanks where

appropriate and selects appropriate samples
for duplicates. CRM’s are inserted
approximately every 50 samples. Sample
preparation checks for fineness are performed
by the laboratory to ensure the grind size of
85% passing 75μm is being attained.
Verification of
sampling and assaying
The verification of significant intersections by
either independent or alternative company
personnel.
Significant intersections are verified by the
Company’s technical staff.
Verification of
sampling and assaying
The use of twinned holes. No twinned holes were completed in the
current drill programme.
Verification of
sampling and assaying
Documentation of primary data, data entry
procedures, data verification, data storage
(physical and electronic) protocols.
Primary data is captured onto a laptop through
excel and using Mx Deposit software and
includes geological logging, sample data and
QA/QC information. This data, together with
the assay data, is stored both locally and
entered into the LGM central online database
which is managed by external consultants. All
primary assay data is received from the
laboratory as electronic data files which are
imported into sampling database with
verification procedures in place. QAQC analysis
is undertaken for each laboratory report
Verification of
sampling and assaying
Discuss any adjustment to assay data. No adjustments or calibrations will be made to
any primary assay data collected for the
purpose of reporting assay grades and
mineralised intervals.
Location of data
points
Accuracy and quality of surveys used to locate
drill holes (collar and down‐hole surveys),
trenches, mine workings and other locations
used in Mineral Resource estimation.
A handheld GPS was used to pick up collars
with an accuracy of +/- 5m. Downhole surveys
are conducted using a downhole Imdex Omni
North Seeking Gyro tool during drilling to
record and monitor deviations of the hole from
the planned dip and azimuth.
