•
•
•
•
Results return from rock samples collected during geological mapping at Rockley reported
anomalous gold and copper values associated with quartz veined and brecciated Ordovician
mafic-ultramafic rocks
Significant results from the rock chip assays include:
o 1.20% Cu, 0.20g/t Au, 21.3g/t Ag, 8ppm Bi
o 0.50% Cu, 60ppb Au, 10ppm Mo, 9.7ppm Ag, 394ppm Pb, 479ppm As
o 0.24% Cu, 0.25g/t Au, 69.3g/t Ag, 1710ppm Sb, 201ppm As
o 0.40g/t Au, 801ppm Cu, 4ppm Bi, 40ppm Li
These results build on the limited historical sampling that returned a best sample of:
o 4.26% Cu, 90g/t Ag, 0.1g/t Au, 2,100ppm As, 5ppm Mo1
These results have defined an anomalous area of copper mineralisation that is ~3 km2 in size
(Crystal Hill Target Area)
The potential of the Crystal Hill Target Area is untested with no systematic porphyry exploration
and only limited shallow (<14m depth) reconnaissance drilling conducted over 25 years ago
Third party prospectivity recognition of the Rockley Project2
o Assessed by Geological Survey of NSW in collaboration with Kenex Pty Ltd to be one of
the most prospective areas for porphyry related Cu-Au in the Rockley-Gulgong Volcanics
Follow up aerial magnetic and radiometric survey is to be completed next month
Management Comment
Legacy Minerals Managing Director, Christopher Byrne said:
“These new rock chip sample assay results support Legacy Minerals’ belief that the Rockley Project
has the potential to host a significant copper gold mineralisation similar to the nearby Racecourse
porphyry copper deposit.
These latest results, across a large 3km2 area, confirm widespread oxide copper mineralisation
including anomalous porphyry pathfinder elements. Fundamental to the prospectivity is that Rockley
is hosted in the same age volcanic rocks as the Cadia-Ridgeway, Racecourse, and Boda deposits.
Our ground has had very limited exploration for porphyry related Cu-Au systems and the
independent prospectivity ranking completed through the Geological Survey of NSW is further
encouragement for the potential of this area.
Incredibly there has not been a single drill hole deeper than 14m in our main target area. Legacy
Minerals plans to be the first company to truly test this area thoroughly.”

Rockley Project Background
The Rockley Project is situated within the highly prospective Ordovician Macquarie Arc volcanics
which hosts the world-class Cadia Valley, North Parkes, and Cowal Cu and Au orebodies. Recent
assessment by Kenex Pty Ltd, in collaboration with the Geological Survey of NSW (GSNSW), found
the Rockley Project area to be the most prospective ground for porphyry-related Cu-Au
mineralisation in the Rockley-Gulgong Volcanics. The tenement is also considered highly prospective
for shear zone hosted gold. The project is located less than 15km from the Racecourse Porphyry Cu
deposit owned by Xtract Resources (AIM: XTR). Historically, limited exploration for porphyry-related
Cu-Au mineralisation has been completed within the tenement despite the numerous historical
gold, copper and lead/zinc mines across the tenement.
Major elements of a porphyry copper gold related system that are present at Rockley include (Ford
et al., 2019):
•
•
•
•
•
•
Oxidised and K-enriched magma present
Benambran contraction fault absent
Reactivity contrast present
Fault bend-jog-splay present
Aeromagnetic reduce-to-pole (RTP) high present which could suggest porphyry-proximal
magnetite enrichment at depth
High Au-Cu-Ag-Zn occurrence density present
Exploration Activity
In 2019, a collaboration between Kenex Pty Ltd and the GSNSW assessed the prospectivity of the
east-Lachlan Orogen for porphyry Cu-Au mineralisation potential. Through this work, the Rockley
Project was identified in multiple areas as being the most prospective area in the entire RockleyGulgong Ordovician volcanics. As such the Rockley project was applied for and extended to include
the prospective Gilmandyke area of the project.

Throughout 2021, historical geochemical and geophysical datasets were compiled and integrated
including regional gravity, magnetics, radiometrics and ASTER data. This data compilation work and
digitisation resulted in a clear exploration strategy for LGM to apply a porphyry copper-gold
exploration model to the Rockley Project.
The initial reconnaissance field mapping and rock chip sampling program was completed in January
2022. This work identified quartz vein, malachite and azurite bearing rocks associated with basalt
and faulting (Figure 2 and Figure 3). The setting is analogous to the Racecourse Deposit, 15km to
the southeast hosted within Rockley-Gulgong volcanics. Historically gossanous rubble assayed
above the Racecourse Deposit up to 0.56% Cu, 220ppm Pb, 420ppm Zn and 7ppm Ag. At Racecourse,
a significant drill intercept of 920m @ 0.3% Cu from 110m including a higher grade of 156m @ 0.48%
Cu from 504m was recently reported3.
The Company took a total of 40 rock chip samples were taken across the northern Rockley Project
area (Figure 1). The area has extensive copper and gold mineralisation as well as important
pathfinder metal assemblages typical of porphyry copper gold systems (K-radiometric high, elevated
Li (up to 40ppm), Bi (up to 8ppm), Be (up to 2.5ppm) and Mo (up to 10ppm)). Notably rock chip 2899
reported 10ppm Mo, 4,950ppm Cu, 60ppb Au, 9.7ppm Ag, 479ppm As, and 394ppm Pb. These
results are suggestive of a porphyry style geochemical signature (Figure 7). Sample 2913 (Figure 4)
was taken within an elevated zone (500m x 200m) of basaltic volcanics which reported Li (2040ppm) and may be suggestive of the higher levels of a porphyry system.

The Company’s work indicates that a major copper-gold mineralised source may be present within
its Rockley Project area where there has been no previous drilling, systematic geochemical
sampling or detailed geophysical surveying.
Importantly, the presence of epithermal-style quartz replacement of bladed carbonate (Figure 6)
may suggest that the high-levels of a hydrothermal system are preserved and there is potential for
preserved porphyry mineralisation at depth.

0.54% Cu, 89ppm Pb, 2,160ppm Zn
Figure 6: Quartz vein presence of quartz replacement of
bladed carbonate (Rockley Quartz Prospect)
Key features identified at the Rockley Project include:
1. The presence of copper oxides (malachite and azurite) and copper sulphides (chalcopyrite)
in rock chips from outcrop and as float near historic workings occur over an area at least
1.5km2 with assays up to 1.2% copper, 0.4g/t gold and 69.3g/t silver with associated
anomalous molybdenum (up to 10ppm), lithium (40ppm), beryllium (2.1ppm) arsenic
(2310) and antimony (1710ppm).
2. The vein textures and pathfinder metal assemblages are suggestive of the outer zones of
porphyry copper-gold mineralisation (Figure 5 and Figure 6).
3. Higher grade copper assays occur in focussed zones associated with 3rd order faults of the
parent Native Dog Fault. These fault zones may have potentially tapped a mineralised
intrusion at depth (Figure 1).
4. The coincidence of an area of extensive copper oxide bearing rocks with several potassium
highs, evident in the radiometric data coincident within the regionally aeromagnetic high
Rockley-Gulgong volcanic unit, may be suggestive of porphyry-proximal magnetite bearing
potassic alteration zones at depth.
The primary porphyry target area occurs in the northern part of the Rockley Project and comprises
a number of intriguing zones of elevated and depressed magnetic and radiometric potassium
responses within Ordovician volcanics. A highly prospective target zone of approximately 1.5km2
has never been drill tested.

Geochemical Exploration for Porphyry Copper Gold Deposits
Fundamental to the exploration process of porphyry copper-gold deposits is to understand the
nature and distribution of pathfinder elements, metal zonation, and alteration mineral
assemblage. These zones form around deposits providing indications to the level of the porphyry
system and vectors to the higher-grade mineralised core (Figure 7).
The zones vary from distal (outer) zones commonly characterised by chlorite-albite-epidote
(propylitic) alteration with pathfinder elements such as arsenic- antimony-lithium-bismuthtellurium-silver. Proximal (middle to inner) zones are characterised by K feldspar-biotitemagnetite-actinolite (potassic) alteration and the pathfinder metals molybdenum-gold-coppertungsten-tin.

porphyry copper-gold mineral system and the relative location of Rockley4,5,6.
Next Steps at the Rockley Project
Following on from the encouraging copper, gold, and pathfinder element assays the Company plans
to systematically explore the Rockley Project with:
• airborne magnetic and radiometric survey will to be flown in late April, with results and
interpretation expected in early May
• a large-scale soil geochemistry program expected to commence in late May, with results and
interpretation received in June

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.
Include reference to measures taken to ensure
sample representivity and the appropriate
calibration of any measurement tools or
systems used.
Rock Chip Samples
Rock chip and grab samples were taken from numerous
locations throughout the prospect areas.
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.
Drill type (e.g., core, reverse circulation, open‐hole
hammer, rotary air blast, auger, Bangka, sonic,

dry.
For all sample types, the nature, quality and
appropriateness of the sample preparation
technique.
Not Applicable.
Rock Chip Samples
The purpose of the rock chip samples was to establish the
tenor of any mineralisation visible in outcrop. Therefore, the
samples are biased towards mineralised samples. This is

The Harden Project is comprised of two granted
Exploration Licenses: EL8809 and EL9257. Both
licenses are owned 100% by Legacy Minerals Pty Ltd
(a fully owned subsidiary of Legacy Minerals
Holdings Limited). There are no royalties or
encumbrances over the tenement areas.
The security of the tenure held at the time of
reporting along with any known impediments to
obtaining a licence to operate in the area.
Acknowledgment and appraisal of exploration
by other parties.
The tenements are in good standing with no known
impediments.
Deposit type, geological setting and style of
mineralisation
Exploration is focussed on the discovery of porphyry
copper-gold mineralisation and shear hosted
mineralisation within Ordovician Volcanics.
A summary of all information material to the
understanding of the exploration results
including tabulation of the following
information for all Material drill holes:
• Easting and northing of the drill hole collar
•Elevation or RL (Reduced Level – elevation
above sea level in metres) of the drill hole collar
• Dip and azimuth of the hole
• Down hole length and interception depth
• Hole length
If the exclusion of this information is justified on the basis
that the information is not Material and this exclusion does
not detract from the understanding of the report, the
Competent Person should clearly explain why this is the case.
In reporting Exploration Results, weighting
averaging techniques, maximum and/or
minimum grade truncations (e.g., cutting of high
grades) and cut‐off grades are usually Material
and should be stated.
Where aggregated intercepts incorporate short
lengths of high-grade results and longer lengths
of low-grade results, the procedure used for such
aggregation should be stated and some typical
examples of such aggregations should be shown
in detail.
The assumptions used for any reporting of
metal equivalent values should be clearly
stated.
