OzAurum Resources Ltd ( ASX: OZM or OzAurum or the Company ) is pleased to announce additional Aircore (AC) drilling results from 75 holes for 5,447 metres (m) of drilling at its Mulgabbie North Project situated two kilometres from the Northern Star Resources (ASX: NST ) Carosue Dam Operations.

Highlights

  • AC holes that intersected significant gold mineralisation from 1m samples of previously released drill holes include:

  • 1m @ 162.5 g/t gold (Au) from 27m - MNOAC 120

  • 1m @ 31 g/t Au from 34m - MNOAC 130

  • 1m @ 15.35 g/t Au from 48m - MNOAC 020

  • AC holes that intersected significant gold mineralisation from 4m composite samples include:

  • 4m @ 10.2 g/t Au from 24m - MNOAC 144

  • 4m @ 2.15 g/t from 20m - MNOAC 144

  • 4m @ 1.49 g/t from 32m - MNOAC 134

Mulgabbie North AC Drilling Results

The 75 AC holes drilled for 5,447m form part of OzAurum’s initial 30,000m AC drilling campaign which began in February this year that has been completed with a total of 434 holes drilled for 30,992m. Results are currently pending for 229 aircore holes. The aircore drilling program has now been extended by 15,000m to undertake infill drilling at Mulgabbie North and complete an initial 4 wide spaced lines at the southern area of E28/2477 at Mulgabbie (see figure 1).

A new significant area, 1km long and up to 150m wide, of widespread gold mineralisation has been intersected by AC drilling situated along and west of the Relief Shear at Mulgabbie North.

One metre gold results have been received for previously released AC holes MNOAC 009 – 130 (see OZM ASX releases 15 March 2021 and 29 March 2021). Significant one metre intercepts include; 1m @ 162.5 g/t Au from 27m (MNOAC120), 1m @ 31 g/t Au from 34m (MNOAC130) and 1m @ 15.35 g/t Au from 48m (MNOAC 020). A number of 1m samples have results that are greater than 1 g/t Au, please see table 3.

Significant new 4m composite AC drilling results from holes MNOAC 131-205 include 4m @ 10.2 g/t Au from 24m, 4m @ 2.15 g/t Au from 20m (MNOAC 144) along with 4m @ 1.49 g/t Au from 32m (MNOAC134) all situated west of the relief shear. Numerous other anomalous gold results can be found in table 2 of this release. The results have provided the Company with exciting new targets that will be followed-up with future RC drilling.

The current interpretation is that high grade gold mineralisation intersected in hole MNOAC 120 (27-28m) is tertiary paleochannel hosted gold mineralisation. Future work will involve the ongoing interpretation of the base of this highly mineralised paleochannel position specifically locating the centre of the base of the mineralised channel facies. This new style of mineralisation will be specifically targeted via future vertical AC drill holes. An approx. 1kg sample of this high-grade interval from MNOAC 120 (27-28m) was panned using a panning dish to determine visible gold present and resulted a long tail of fine gold being observed - see photograph 1.

Another exciting aspect of the completed AC drill program at Mulgabbie North is the number of aircore holes drilled at the northern area of the project have intersected sericite, +- hematite alteration with associated pyrite and in some cases arsenopyrite + pyrite mineralisation at the end of hole sample. Gold mineralisation at Mulgabbie North typically is associated with pyrite and or arsenopyrite mineralisation. The assay results for these holes are still outstanding and we are eagerly awaiting the results of these aircore holes.

Widespread gold mineralisation at this new 1km long zone is currently open to the north. In addition, the new gold zone is co-incident with OZM gold auger calcrete geochemistry anomalies, and a gravity low trough similar to the Northern Star Carouse Dam corridor of riches in which their operating gold mines are situated, including production of about 1.5 million ounces to date.

Another important aspect of this drilling program is a 40-80m wide zone of hematite alteration being intersected in the bottom of the AC holes (as announced on 15 March 2021) now defining a trend striking NW for approximately 2.5 kms, and situated 150m west of the Relief Shear. Hematite alteration is the characteristic alteration of the adjacent Northern Star’s Karari and Whirling Dervish Gold Mines. The hematite alteration observed is indicating oxidised fluids from an intrusive complex suggesting proximity to the mineralising centre- likely to be within OzAurum’s 100% owned Mulgabbie North tenure.

Aircore drilling is now being undertaken on the southern area of E28/2477 where holes are being drilled at 1km x 80m spacing. This area is the interpreted position of the southern extension of the Relief Shear. Transported cover up to 40m thick has prevent effective exploration of this area. There is no historic drilling in this area. Early visual signs of bottom of hole chips is encouraging with sericite altered volcaniclastic rocks being intersected with pyrite mineralisation. This drilling is expected to take up to a month to complete. Please refer to figure 1 for the location of this area.

The Mulgabbie North infill AC drilling program will be undertaken on a 100m x 40m drill spacing extending existing drill lines to the west. Of particular interest in this area is MNOAC 115 that intersected 3m @ 2.28 g/t from 71m and a number of other holes that have intersected anomalous gold mineralisation. All holes are being drilled to top of fresh rock using the AC blade bit drilling to refusal, and utilising the aircore hammer where required. This is a critical drilling technique to discover gold mineralisation in fresh rock. Historic Freeport RAB holes drilled in 1984-1988 in the same area failed to reach the top of fresh rock in the highly prospective intermediate-felsic lithology due to transported cover and the shallow water table.

OzAurum’s Chief Executive Officer, Andrew Pumphrey, said:

“The Company is excited about the continued high-grade AC intercepts being received from our largescale drilling campaign. This is a new widespread zone of gold mineralisation situated west of the Relief Shear which provides even greater confidence in the Project. In particular, we are excited by the potential of this area where the host rocks are intermediate-felsic volcaniclastic units - very similar to the Northern Star Carosue Dam Karari and Whirling Dervish Gold Mines. In addition, a new 40-80m wide zone of Hematite alteration extending for 2.5km intersected for the first time in AC holes is very promising since this is a key signature of the adjacent Northern Star Carosue Dam Karari and Whirling Dervish Gold Mines that have so far produced about 1.5 million ounces of gold. Lastly, this area is under transported cover that has prevented previous effective exploration and now represents a significant exploration opportunity for the Company.”

In the coming months as drilling results become available the company will be providing the market with regular updates. Laboratory assay results are currently taking up to 8 weeks from time of delivery causing delays in results being released to the market.

JORC Code, 2012 Edition – Table 1 Report

Section 1 Sampling Techniques and Data

(Criteria in this section apply to all succeeding sections.)

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.
The Mulgabbie North Project 75 AC holes
(MN0AC 131 - 205 5447m), azimuth 225°
dipping -60°.
The RC samples are collected from the drill rig
cyclone in a green plastic bag in 1m intervals
and are laid out in rows of either 20, 30 or 40
samples. A 2-4kg representative sample is
split via the rig mounted cone splitter and
placed on top of the green plastic for that
metre interval.
Diamond drilling completed using one metre
sampling lengths, core half cut adjacent to
bottom of hole orientation line.
Aircore samples are laid out in rows of 10.
Include reference to measures taken to
ensure sample representivity and the
appropriate calibration of any
measurement tools or systems used.
All sampling is undertaken using OzAurum
Resources sampling procedures and QAQC
in line with industry best practise which
includes certified standards and blanks every
30 samples.
The RC drill rig provides a sample at the end
of each metre of drilling. A 2-4 kg sample is
collected from the drill rig via a cone splitter
which is representative of that metre.
PQ diamond core was half cut to produce a 2-
4 kg sample for analysis.
Aircore 4m composite samples weighing
between 2-4 kg are collected from four one
metre samples via a sample scoop with even
quantities of each 1m sample collected to form
the composite sample. At the EOH if the
composite interval is less than 4m then that
will be sample interval.
Aspects of the determination of
mineralisation that are Material to the
Public Report.
Historic hole collars have been recovered
where possible and surveyed by a licenced
surveyor using a DGPS (0.01 m).
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
The RC one metre sample intervals were
collected with a 2-4 kg representative sample
despatched to the laboratory for gold analysis.
The diamond half core sample intervals were
typically a 2-4 kg representative sample
despatched to the laboratory for gold analysis.

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 AC composite and one metre sample
intervals were collected with a 2-4 kg
representative sample despatched to the
laboratory for gold analysis.
All analysis was by 50g fire assay with AAS
finish with the exception of cases where visible
gold has been observed or a fire assay grade
has exceeded 100 g/t or coarse gold is
suspected then a screen fire assay (Au-
SCR22AA) has been undertaken on those
samples and those results reported instead of
the fire assay result.
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).
The RC drilling was undertaken using a face
sampling percussion hammer using 137mm
drill bits.
The diamond drilling was undertaken using
PQ3 (triple tube) and NQ3 (standard tube)
techniques.
The AC drilling was undertaken using a 75m
blade bit and face sampling percussion
hammer using 78mm drill bits.
Drill sample
recovery
Method of recording and assessing core
and chip sample recoveries and results
assessed.
Each metre of RC sample is checked, and an
estimate of sample recovery is made. For this
program, greater than 80% of samples had a
recovery of 70% or higher. Sample weights
reported by laboratory can also give an
indication of recoveries.
Drill core was measured and compared to
drilled intervals and recorded as a percentage
recovery. Recovery in oxidised rock can be
reasonable whereas recovery in fresh rock is
excellent.
Each metre of AC sample is checked, and an
estimate of sample recovery is made. For this
program, greater than 80% of samples had a
recovery of 70% or higher. Sample weights
reported by laboratory can also give an
indication of recoveries.
Measures taken to maximise sample
recovery and ensure representative
nature of the samples.
Drillers’ experience is important. Steady
drilling, using modern well maintained drilling
equipment, regular cleaning of cyclone and
splitter, pausing the drilling at each metre to
allow sample to pass through drill string and
reducing sample loss. Using a RC rig
equipped
with
auxiliary
and
booster
compressors is critical to maintaining good RC
sample recovery.

recoveries through the use of appropriate
drilling equipment techniques and drilling
fluids
suited
to
the
particular
ground
conditions.
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.
RC sample recoveries from the mineralised
zones are generally high although some of the
weathered material is lost in drilling (dust) and
some natural voids do exist. No sample was
lost from 2-4 kg split from cyclone that was
submitted for analysis, some loss of sample
occurred from large green bags and some
bias may have occurred to that sample as
water was flowing from sample bag – this
sample has not been analysed and therefore
will not affect results reported in this release.
The core sample recovery in the transitional
and fresh rock zones is very high and no
significant bias is expected. Recoveries in
oxidised rock were lower.
AC sample recoveries from the are generally
high although some of the weathered material
is lost in drilling (dust).
Although no exhaustive studies have been
undertaken, no significant bias is expected,
and any potential bias is not considered
material
at
this
stage
of
resource
development.
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.
Each RC metre drilled underwent detailed
logging through the entire hole with record
kept of colour, lithology, degree of oxidation,
and type and intensity of alteration veining and
sulphide content.
Diamond core metres underwent detailed
logging through the entire hole with record
kept of colour, lithology, degree of oxidation,
and type and intensity of alteration, veining
and sulphide content. Structural, density and
geotechnical data is also collected on drill
core.
Each AC hole drilled underwent general
logging through the entire hole with record
kept of colour, lithology, degree of oxidation,
and type and intensity of alteration veining and
sulphide content.
Whether logging is qualitative or
quantitative in nature. Core (or costean,
channel, etc) photography.
All logging is qualitative in nature and included
records of lithology, oxidation state and colour
with estimates of intensity of mineralisation,
alteration and veining.
Wet and dry photographs were completed on
the core.

The total length and percentage of the
relevant intersections logged.
All drill holes were geologically logged in full
(100%).
Sub-sampling
techniques and
sample
preparation
If core, whether cut or sawn and
whether quarter, half or all core taken.
Core was half cut with a diamond saw with the
same half always sampled and the other half
retained in core trays.
In some instances, oxidised and non-
competent clay zones are carefully split in half
using sampling wedge and sampled as half
core.
If non-core, whether riffled, tube
sampled, rotary split, etc and whether
sampled wet or dry.
All RC sub-samples are collected via a cone
splitter system mounted on the drill rig. An
estimated 30% of samples were moist to wet
in nature that passed through the cyclone –
splitter system.
For all sample types, the nature, quality
and appropriateness of the sample
preparation technique.
All samples were analysed via a 50 gram fire
assay. Following that analysis in cases where
visible gold has been observed or a fire assay
grade has exceeded 100 g/t or coarse gold is
suspected then a screen fire assay (Au-
SCR22AA) has been undertaken on those
samples and those results reported instead of
the fire assay result.
Sample
preparation
and
analysis
were
completed by ALS in Kalgoorlie. When
received, samples are processed by code
PREP-31 - logged in tracking system and bar
code attached, wet samples dried through
ovens, fine crushing to better than 70%
passing 2mm, split sample using riffle splitter,
split of up to 1000g pulverised to >85%
sample passing 75um.
Quality control procedures adopted for
all sub-sampling stages to maximise
representivity of samples.
All sampling equipment and sample bags are
kept clean at all times.
The RC drill rig mounted cone splitter is
adjusted to ensure that the 1m split sample
weighs on average between 2-4kg. The cone
splitter is cleaned using an air nozzle after
every drill rod – 6m.
OzAurum Resources sampling procedures
and QAQC is used to maximise representivity
of samples.
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.
For drill core, the entire core is sampled at one
metre intervals to ensure that samples are
representative of the entire in-situ rock being
tested. The laboratory ensures that the entire
sample submitted is crushed and split

appropriately to provide a representative sub-
sample.
No duplicate samples are taken from the core
Whether sample sizes are appropriate to
the grain size of the material being
sampled.
The sample sizes (0.5 kg to 4 kg) are
considered appropriate for the style of
mineralisation at Mulgabbie North.
Half cut PQ diamond core samples over 1m
length (normally at the end of hole) were up to
4kg.
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.
The nature, quality and appropriateness of the
assaying and laboratory procedures are
industry standard for Archaean mesothermal
lode gold deposits. The fire assay technique
will result in a total assay result. In cases
where visible gold has been observed or a fire
assay grade has exceeded 100 g/t or coarse
gold is suspected then a screen fire assay
(Au-SCR22AA) has been undertaken on
those samples and reported instead of the fire
assay result.
For geophysical tools, spectrometers,
handheld XRF instruments, etc, the
parameters used in determining the
analysis including instrument make and
model, reading times, calibrations
factors applied and their derivation, etc.
None of these tools are used
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.
Certified Reference Materials (standards) are
purchased from an independent supplier of
such materials. Blanks are made up from
samples previously collected from other drill
programs at Mulgabbie North that have
analysed as less than detection Au values.
A standard sample followed by a blank sample
are inserted every 30thsample. A duplicate
sample is taken every 30 samples.

The verification of significant
intersections by either independent or
alternative company personnel.
At least two different company personnel
visually verified intersections in the collected
drill chips. At least two different company
personnel visually verified intersections in the
diamond core. A representative sample of
each metre is collected and stored for further
verification if needed. Drill core or core photos
are used to verify drill intersections in diamond

CRITERIA JORC CODE EXPLANATION COMMENTARY
Data spacing and
distribution
Data spacing for reporting of Exploration
Results.
Drilling at Mulgabbie North is at:
20m line x 10m hole
20m line x 20m hole
40m line x 20m hole
The holes reported in this release were on
20m spaced lines that are 20m apart along the
lines.
Whether the data spacing, and
distribution is sufficient to establish the
degree of geological and grade
continuity appropriate for the Mineral
Resource and Ore Reserve estimation
procedure(s) and classifications applied.
The data spacing and distribution is sufficient
to demonstrate spatial and grade continuity of
the mineralised domains to support the
current MRE classifications as Measured,
Indicated and Inferred according to JORC
(2012 Edition) reporting criteria.
Whether sample compositing has been
applied.
No sample compositing has been applied in
the field within the mineralised zones.
Orientation of
data in relation to
geological
structure
Whether the orientation of sampling
achieves unbiased sampling of possible
structures and the extent to which this is
known, considering the deposit type.
Diamond drill holes and RC holes were
orientated 225°/-60° which is perpendicular to
the shear zone hosting gold mineralisation
and perpendicular to geology contacts.
If the relationship between the drilling
orientation and the orientation of key
mineralised structures is considered to
have introduced a sampling bias, this
should be assessed and reported if
material.
It is not believed that drilling orientation has
introduced a sampling bias as the dominant
mineralised shear zone at Mulgabbie North
hosting mineralisation strikes at 315° and dips
70°NE.
Sample security The measures taken to ensure sample
security.
Chain of custody is managed by OZM. Field
samples are stored overnight onsite at site
office + camp facility (if not delivered to
laboratory) with staff in residence who are
employees of OzAurum.
Field samples are delivered to the assay
laboratory in Kalgoorlie by OZM personnel
once the hole is completed. Whilst in storage
at the laboratory, they are kept in a locked
yard. ALS Geochemistry Webtrieve is used
online to track the progress of batches of
samples through the laboratory.
Sample pulps and coarse rejects are stored at
ALS for a period of time and then returned to
OZM.

Data
aggregation
methods
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.
All one metre diamond drill results are
reported in Appendix 1 Section 2 of JORC
table 1. Holes include up to 2m of internal
dilution - host unit was intersected in the
2m diluted section with significant
alteration. A bottom cut off grade of 0.1 g/t
was used, and no top cut grade was
applied.
The procedure applied to the aggregate
intercepts quoted is length weighted
average (sum product of interval x
corresponding interval assay grade),
divided by sum of interval lengths and
rounded by one decimal place.
No metal equivalent values have been
reported.
Where aggregate intercepts
incorporate short lengths of high
grade results and longer lengths of

These relationships are particularly
important in the reporting of
Exploration Results.
These drill holes are designed to drill
perpendicular to the Relief Shear that
strikes at 315°.

reported. 315˚ and is moderately dipping to the
east at -75°.
The true width of mineralisation at the
Mulgabbie North is reasonably well known
from existing drilling and all drilling is
designed to intersect the Relief Shear
mineralised envelope at 90° or
perpendicular to the strike of the Relief
Shear. The -60° planned dip of all drill
holes results in the true width being 70%
of the downhole intersection. For
example, a downhole intersection of 10m
has a true width of 7m.
If it is not known and only the down
hole lengths are reported, there
should be a clear statement to this
effect (e.g. ‘down hole length, true
width not known’).
Diagrams Appropriate maps and sections (with
scales) and tabulations of intercepts
should be included for any
significant discovery being reported
These should include, but not be
limited to a plan view of drill hole
collar locations and appropriate
sectional views.
(NOTE: Any map, section, diagram,
or other graphic or photo must be of
high enough resolution to clearly be
viewed, copied and read without
distortion or loss of focus).
Please refer to the body of the report.
Balanced
reporting
Where comprehensive reporting of
all Exploration Results is not
practicable, representative reporting
of both low and high grades and/or
widths should be practiced to avoid
misleading reporting of Exploration
Results.
Please refer to table 1 in the body of the
report.
Other
substantive
exploration
data
Other exploration data, if meaningful
and material, should be reported
including (but not limited to):
geological observations;
geophysical survey results;
geochemical survey results; bulk
samples – size and method of
treatment; metallurgical test results;
bulk density, groundwater,
geotechnical and rock
characteristics; potential deleterious
or contaminating substances.
The diamond holes were also utilised for
bulk density measurements.
