Management comment – Legacy Minerals CEO & Managing Director Christopher Byrne said:
“The latest results have delivered shallow and high-grade hits up to 468g/t Ag, 22% Zn+Pb and 3.8g/t Au
from wide-spaced reconnaissance drill testing.
“This is encouraging as we’re confirming multiple vein trends with strong mineralisation that until now had
never before been drill tested. The success at these targets further highlights the potential of the large
anomalous areas that remain undrilled and the potential of the Bauloora system that remains open in all
directions.
“An exciting takeaway is the success rate of intercepting mineralisation on the Bauloora Project. Out of four
previously undrilled prospects, three have returned promising results. The single hole into the fourth
prospect, Marry Bugg, delivered over a 200m zone of alteration that provides further encouragement to
the size of the mineral system at Bauloora and is supported by the widespread surface soil and rock chip
anomalism.
“We have another drilling campaign planned at Bauloora for later this year, and we look forward to
providing further updates on the Project over the coming months.”

Legacy Minerals Holdings Limited (ASX: LGM, “Legacy Minerals” or “the Company”) is pleased to
provide an update on the drilling completed at the Bauloora Project (EL8995 and EL9464) in the
Lachlan Fold Belt, NSW.
Daimond Drilling Results
On the Bauloora Project, eight diamond holes have been completed for a total of 1,437.1 metres.
These tested four prospects defined by a combination of anomalous soil and rock chip geochemistry
and geophysical signatures. The diamond drill holes have confirmed epithermal-style veins beneath
elevated gold, silver, and pathfinder rock chip and soil geochemical results and mapped veins.

0.6% Cu from 107.9m. BK001 intersected alteration and anomalous gold from start of hole to
approximately 140m. Strong alteration was associated with the two main epithermal vein zones
intersected between approximately 28-37m and 102-108m. A number of anomalous zones were
intercepted including 2.7m at 0.23g/t Au, 8.64g/t Ag, 1.62% Zn and 0.95% Pb from 105.3m.
At the Bauloora East Prospect, a single diamond drill hole was completed to 150.5m. This drill hole
tested the southernmost extent of the large 1,500m x 150m zone of elevated gold, base-metals and
other pathfinder elements defined in soil sampling. Rock chip sampling has returned gold and silver
grades up to 8.52g/t Au. Better intercepts reported include 1m at 10g/t Ag, 4.86% Zn and 1.73% Pb
from 111.5m.

About the Bauloora Project
Legacy Minerals’ Bauloora Project is located in the Lachlan Fold Belt of New South Wales which is host
to world-class copper-gold orebodies including the Cadia-Ridgeway, Northparkes, and Cowal Mines.
In 2023, Newmont Exploration Pty Ltd entered into a Farm-In and Joint Venture on the Project iii. It
covers a large hydrothermal alteration zone 27km2 in size, within which is an anomalous gold zone
currently mapped to 15km2. Rock chip and soil samples collected by the Company from the Project
area have highlighted several priority areas of anomalous precious metal values with highly
anomalous values of epithermal pathfinders iv. The drilling of the first of these targets resulted in the
discovery of the Bluecap Prospect returning 13m at 1.66g/t Au, 6.68g/t Ag, 0.14% Cu and 4.23% Pb+Zn
from 57miv.

Extensive epithermal alteration exists on the Project, including widespread zones of high-level
chalcedonic veins, clay alteration and local sinter formations. The Project has seen very limited
exploration drilling and the Company believes the results from work to date support the assessment
that there is potential for the discovery of a low-sulphidation epithermal-style gold-silver deposit at
the Bauloora Project.

Appendix 2 – JORC Code, 2021 Edition Table 1
Section 1 Sampling Techniques and Data
Criteria
JORC Code Explanation
Commentary
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 was PQ core (diameter: 85mm) to
fresh rock and HQ core (diameter: 63.5mm) to
end of hole (EOH). LGM used a reputable drilling
contractor, Ophir Drilling, with a suitable rig.
Diamond drill core provide a high-quality sample
that is logged for lithological, structural,
geotechnical, and other attributes. Subsampling of the core is carried out as per
industry best practice.
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.
Sampling
Techniques
Include reference to measures taken to ensure
sample representivity and the appropriate
calibration of any measurement tools or systems
used.
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.

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 1m 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.
The drill core was cut by LGM staff. Samples
were transported to ALS Laboratory in Orange
for assaying. Samples are crushed to 6mm and
then pulverized to 85% passing 75 microns. A
50g split of the sample was fired 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 using a 4-acid acid digest and an
ICP finish (ALS code: ME-MS61 + Au-AA21 + HgMS42).
Assay standards, blanks and duplicates were
analysed as part of the standard laboratory
analytical procedures. Company standards were
introduced into the sampling 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).
Method of recording and assessing core and chip
sample recoveries and results assessed.
Drill sample
recovery
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.
Diamond drilling using industry standard
techniques. HQ core (diameter: 63.5mm) to end
of hole (EOH).
Core recoveries were recorded during drilling
and reconciled during the core processing and
geological logging.
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.
To date, minimal sample recovery issues have
been identified that would impact on potential
sample bias in the competent fresh rocks that
host the mineralised intervals.
Systematic geological and geotechnical logging
was undertaken. Data collection where
appropriate includes:
• Nature and extent of lithologies.
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.
• 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 ulk density by Archimedes
principle may be taken.
Whether logging is qualitative or quantitative in
nature. Core (or costean, channel, etc)
photography.
The total length and percentage of the relevant
intersections logged.
• Magnetic susceptibility recorded at 1m
intervals for some holes as an orientation and
alteration characterisation tool.
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.
All drill holes are geologically logged in full.
Core was cut using a conventional automatic
core saw with core holding support. All samples
are collected from the same side of drill core.
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.
Sub‐sampling
techniques and
sample
preparation
For all sample types, the nature, quality and
appropriateness of the sample preparation
technique.
Quality control procedures adopted for all
subsampling stages to maximise representivity of
samples.
Measures taken to ensure that the sampling is
representative of the in situ material collected,
A half-core sample is submitted for assay
analysis. Where core was incompetent due to
being transported cover, weathered rock, or
soft rock due to faulting, representative samples
were collected along the axis of the core. This
information is recorded in the cut-sheet and
loaded into database.
Not applicable as results are for core drilling.
Drill core is cut in half along the length and the
total half core submitted as the sample. This
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 were delivered by Legacy Minerals
Holdings personnel to ALS Minerals Laboratory,
Orange NSW. 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.
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.
No sub-sampling is completed by LGM. All subsampling of the prepared core is completed by
the laboratory.
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.
The sample sizes are appropriate to correctly
represent the mineralization based on style of
mineralisation.
All samples were analysed by ALS Global.
Samples are 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 (total 48 element suite) are analysed
using a 4-acid acid digest and an ICP finish (ALS
code: ME-MS61 + Au-AA21 + Hg-MS42) and
undergo spectral analysis (TRSPEC-20).
No geophysical tools or other handheld XRF
instruments were used to determine grade.
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.
The use of twinned holes.
No twinned holes were completed in the
current drill programme.

Primary data is captured onto a laptop through
excel and using Datashed 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
No adjustments or calibrations will be made to
any primary assay data collected for the
purpose of reporting assay grades and
