Large Low Sulphidation System Highlighted by GA-IP Survey
New areas of interest identified sub-parallel to known gold veining at Bauloora Project
“Au-Ag mineralisation, scale, alteration and preservation”
•
The Company has completed a large 81km, 50m line spaced gradient array induced
polarisation (GA-IP) survey at the Bauloora Project.
•
The GA-IP encompassed the northern section of a 4km by 2km zone of elevated gold-in-rock
chip samples (>0.1g/t Au).
•
Interpretation of the results by GeoDiscovery Group and the Company has highlighted
numerous prospective areas.
•
These targets may represent disseminated sulphides (chargeable) or quartz veins and/or
silica alteration (resistive).
•
These areas are defined by significant chargeable and resistive targets (Figure 1) that, in
places, directly correlate to the known mineralisation at the Mee Mar Prospect (quartzcarbonate-adularia veins) and Bauloora East Prospect (carbonate base-metal veins) giving
encouragement to newly defined highly prospective areas along strike and sub-parallel.
•
Results indicate chargeable and resistivity targets are open along strike and to the east.
•
Newly identified chargeable features coincide with historical shallow reverse circulation (RC)
drilling that intercepted up to 3m at 1.13g/t Au, 15.8g/t Ag, 34ppm Hg and 7.2% Pb+Zn from
69m1.
Management Comment
Legacy Minerals Managing Director, Christopher Byrne said:
“Our recently completed GA-IP survey has contributed significantly to our interpreted prospectivity
at the Bauloora Project. The survey forms part of our approach to systematically explore and drill
the Project and we are excited to see the early fruits of this work.
The GA-IP survey focused on the northern section of an 8km2 anomalous gold zone, and the findings
of this survey are highly significant for Legacy Minerals. The survey results support a correlation of
identified target areas with historical gold in drill intersections. The important implication of this
correlation with gold mineralisation, is that the survey has defined similar chargeability and
resistivity responses over a 2km strike length that has seen virtually no drilling.
Importantly, what we see in the Bauloora Project is all the right ingredients for a significant lowsulphidation epithermal discovery: extensive gold and silver mineralisation, scale, alteration and
system preservation.”

Results and Implications
The GA-IP survey has defined a large area which exhibits elevated and anomalous chargeability and
resistivity responses over a 2km strike length. Zones of elevated chargeability and resistivity are
found proximal to interpreted and known veins and mineralisation within the Bethungra and
Cowcumbala Volcanics (Figures 2 - 6).
Results returned from the GA-IP survey indicate correlation between chargeability and observed
clay alteration in the Bethungra volcanics, as well as with historical Mee Mar prospecting pits
(Figures 4 & 5) and mapped veining that has strong gold, silver and base-metal intersections
reported in historic drill holes (e.g. HB4: 3m at 1.13g/t Au, 15.8g/t Ag and 7.2% Pb+Zn from 69m).
Chargeable anomalies within the Bethungra rhyolites and dacites that have been identified in the
central and western parts of survey area are of significant interest as they present a contrast to the
interpreted resistive bedrock lithology.
Resistive anomalies have also been shown to occur with known veining and surface gold
mineralisation at Bauloora North (Figures 2 & 3), the Mee Mar vein and at Bauloora East (Figure 6).
Resistive anomalies may represent quartz veining and/or zones of silica alteration associated with
gold and silver mineralisation. These resistive targets may represent the response of an extensive
low-sulphidation quartz-carbonate vein system.
Target areas of interest extend along strike (north and south) and to the east of the current survey.
The Company is currently assessing plans to extend the survey to these areas in the future. The
limited drilling at the Bauloora project and the anomalies defined through the GA-IP survey have
highlighted the untested prospectivity. Significantly, the Company interprets high levels of the low
sulphidation system to be preserved due to the presence of sinter related lithology, and diagnostic
vein textures and geochemistry. This Project therefore, represents an excellent opportunity for a
shallow high-grade gold and silver discovery to be made.

Gradient Array Induced Polarisation
Gradient array is an efficient way to map horizontal variations in subsurface resistivity and
chargeability. Resistive highs may represent zones of silica alteration and quartz veining that may
be associated with gold and silver. Chargeability highs potentially represent zones of disseminated
sulphides such as pyrite or arsenopyrite that may be associated with mineralisation.
GA-IP is often used as a first pass to highlight general regions of chargeable or resistive response,
then dipole-dipole (DP-DP) or pole-dipole (P-DP) surveys are commonly completed to provide
additional depth penetration to target drill holes. No depth information is acquired with gradient
array set-up however the significant benefit is its ability to cover a large area of ground quickly and
cost effectively.
Legacy Minerals retained Fender Geophysics Pty Ltd to complete a total of 81km of surveying over
the Company’s Bauloora Project. This was to forward the Companies systematic exploration
strategy at the project and build upon the results of the ground magnetic survey. The survey covered
the majority of the known Mee Mar strike length and prospects including Bauloora East and
Bauloora North within the northern portion of the gold anomalous zone.
The GA-IP data received is of good quality and data interpretation remains ongoing. The data was
acquired in 4 blocks as shown in Figure 8. Each data block measures 1km x 1km with potential
electrodes located 2km apart (500m to the east and west of each data block). Some survey stations
overlap between blocks has been incorporated in the design to allow for data continuity. Stations
were acquired at 25m intervals along on E-W lines 50m apart.

A number of readings were taken and the final field data was assessed in the software program TQIP
(by Scientific Computing and Applications). IP decays were compiled and inspected for each reading
in Geosoft. Sub-standard (i.e., non-monotonically decreasing, negative or excessively erratic) decays
were rejected and multiple readings averaged. A representative chargeability decay was calculated
for all suitable decays.
A number of fences are located in the region and may affect the results. Around 5% of points were
rejected (mostly the spuriously high but repeatable IP decays occurring near marked fences). The
fences have been plotted from points supplied by Fender Geophysics. Anomalies proximal to culture
are treated with caution.
Drilling Completed – Mt Felstead
Ten RC holes have been completed at the Mt Felstead Project with intersections of vein-hosted
base-metal mineralisation up to 10m down-hole width2 including zones of semi-massive sulphides.
All holes have been dispatched and assay results are pending with results expected within 8 weeks.
The holes ranged from 120 to 220 metres depth and the interpreted position of the mineralised
structure was intercepted in nine of the ten holes.
Host rocks were variably silicified rhyodacite tuffs, with sericite alteration noted in association with
shearing and chlorite alteration increasing in intensity adjacent to quartz-carbonate veins. Sulphides
were observed to occur with quartz-carbonate veining. These veins consisted primarily of finegrained yellow sphalerite and fine grained “sooty” galena with minor chalcopyrite and disseminated
pyrite interpreted to be of a similar mineralisation style to that historical mined at Mt Felstead
(Figure 7).
The drilling tested down dip of known mineralisation and along a 650m strike of historically mined
mineralisation and anomalous soil geochemistry1. The Mt Felstead Prospect exhibits carbonate base
metal epithermal-style gold-silver mineralisation which historically reported bonanza Ag and highgrade Au with historic face sampling assays up to 3,701g/t Ag, 6.9g/t Au, 55% Pb+Zn, and 6.4% Cu
(20cm face grab sample) 1. The Company looks forward to updating the market on the results once
they return.

Next Steps at the Bauloora Project
The significance of the results from the GA-IP survey, when combined with known anomalism and
alteration, has increased the prospectivity at the Bauloora Project. The Company is now prioritising
follow-up work to define further drill targets at the project including:
• large soil geochemistry program; and
• ground truthing GA-IP and reconnaissance rock chip sampling.
The Company will be completing down hole electromagnetic (DHEM) surveying at the Mt Felstead
Mine prospect with three initial holes be surveyed in early April. If results are encouraging and the
survey technique is deemed appropriate for helping target Mt Felstead style of mineralisation the
DHEM surveys will be expanded to the remaining RC holes.
The Company has planned and budgeted for ~5,000m of RC drilling across the Bauloora Project. To
date the company has completed 1,541m of drilling at Mt Felstead.

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.
Gradient Array Induced Polarisation survey (GA-IP) method is often used
to determine the location of disseminated sulphides. Rocks containing
sulphide minerals can be more readily charged than barren ground. An
external current is applied, and charge separation can occur on sulphide
grain boundaries. When the transmitted current is switched off the
decay of the current can be measured. Gradient array is an efficient way
to map horizontal variations in subsurface resistivity and chargeability,
but it is poor at resolving depth of anomaly.
The IP survey was completed by Fender Geophysics. The oversight of
the survey and auditing (QAQC) and processing of data acquired was
conducted by the Fender Geophysics team and GeoDiscovery Group Pty
Ltd.
The GA-IP survey array used a GDD Tx 4 5kVA transmitter and a Scintrex
IPR12 8-Channel receiver. The receiver dipole length was 25m and the
transmitter dipole length 2000m. The time domain was 2s or 0.125Hz.

• Manual recording of station location, current output, primary voltage,
resistivity and chargeability
• Between 2 and 13 fold stacking for each reading, with visual
inspection of individual decay stacks
• Minimum of 3 readings per station, thus verifying repeatability of the
recorded values

These relationships are particularly important in
the reporting of exploration results. If the
geometry of the mineralisation with respect to
the drill hole angle is known, its nature should

appropriate sectional views.
Where comprehensive reporting of all
