ASX Announcement

8 March 2021

Outstanding Intercept of 4m at 10.26g/t Gold within 10m at 4.6 g/t Gold in Maiden RC Drill Program

OzAurum Resources Ltd ( ASX: OZM or OzAurum or the Company ) is pleased to announce the first Reverse Circulation (RC) drilling results from nine holes for 1929 meters (m) of drilling at its Mulgabbie North Project situated two kilometres from the Northern Star Resources (ASX: NST ) Carosue Dam Operations.

Highlights

  • High grade gold mineralisation intersected, open along strike and at depth.

  • Currently 31 RC holes totalling 6,327m and 137 Aircore holes totalling 9,781m already completed with remaining assays pending.

  • Drilling ongoing to reach target stage 1 50,000m campaign.

  • Strong cash position with A$12m raised at IPO in February 2021.

  • All nine RC holes intersected significant gold mineralisation, including:

    • 4m @ 10.26 g/t gold (Au) – Including 1m @ 14.60 g/t Au (within 10m @ 4.6 g/t Au from 48m)

    • 8m @ 3.41 g/t Au – Including 1m @ 7.50 g/t Au, 1m @ 7.18 g/t Au and 1m @ 5.88 g/t Au (from 135m)

    • 7m @ 2.90 g/t Au – Including 2m @ 6.39 g/t Au (from 184m)

    • 7m @ 2.44 g/t Au – Including 1m @ 5.24 g/t Au (from 81m)

    • 6m @ 2.34 g/t Au (within 20m @ 1.25 g/t Au from 156m)

    • 1m @ 5.77 g/t Au (from 253m)

  • Wide zones of Hematite alteration intersected in some deeper holes- a key signature of the adjacent Northern Star Karari and Whirling Dervish Gold Mines.

Mulgabbie North RC Drilling Results

The first nine holes drilled for 1929m are just the beginning of OzAurum’s initial 20,000m RC drilling campaign. All nine RC drill holes have intersected significant gold mineralisation in a highly altered intermediate/felsic volcaniclastic unit that is interpreted to be a stratigraphic equivalent to an Upper Black Flag unit. The key characteristic of this particular Upper Black Flag unit is the presence of fuchsite altered clasts within the mineralised clastic unit.

Gold Mineralisation at Mulgabbie North Ben Prospect is currently open at depth and along strike. Of particular interest is hole MNORC 011 that intersected 2m @ 6.39 g/t at 184 m downhole depth. This is an exciting target for future deep drilling.

Another important aspect of this drilling program was the intersection of wide zones of hematite alteration in some RC holes, which is the first time that this alteration style has been intersected at Mulgabbie North. Hematite alteration is the characteristic alteration of the adjacent Northern Star’s Karari and Whirling Dervish Gold Mines. The hematite alteration observed at the Ben Prospect 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.

The planned RC drilling at Mulgabbie North will test strike and depth extensions of gold mineralisation at the James and Ben Prospects that are situated on the Relief Shear. Gold mineralisation at these prospects is hosted in the intermediate – felsic volcaniclastic units that is similar to Northern Star’s Karari and Whirling Dervish Gold Mines. The planned RC drilling program at Mulgabbie North will scope out the extent of known mineralisation aimed at making a significant gold discovery.

Utilising best practice RC drilling, sampling and assays protocols will allow for a potential future JORC 2012 compliant resource to be estimated with confidence at Mulgabbie North. Systematic RC drilling is being undertaken on a 20m x 20m spacing and a limited number of historic + 33 year old RC drill hole positions will be redrilled to meet JORC 2012 requirements.

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

“The Company is thrilled that we have been able to generate these high-grade intercepts so early on in our large-scale drilling campaign. In particular, we are excited by the potential of this area where the host rocks are intermediate-felsic volcaniclastic units- very similar to the Karari and Whirling Dervish Gold Mines. In addition, the wide zones of Hematite alteration intersected for the first time in some deeper holes is very promising since this is a key signature of the adjacent Northern Star Karari and Whirling Dervish Gold Mines. Lastly, this area is under transported cover that has prevented previous effective exploration.”

In the coming months as drilling results become available the company will be providing the market with regular updates.

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.
Using professional and competent core
drilling contractor minimises issues with
sample 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 largegreen bags and

11

CRITERIA JORC CODE EXPLANATION COMMENTARY
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

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

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

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.
Evaluation of the OzAurum submitted
standards and blanks analysis results
indicates that assaying is accurate and
without significant drift.
Verification of
sampling and
assaying
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 core samples.
The use of twinned holes. The spatial location and assaying accuracy of
historical drilling was confirmed with RC and
DD twinned holes.

hole surveys), trenches, mine
workings and other locations used in
Mineral Resource estimation.
Initial hole collars surveyed by licenced
surveyor DGPS (0.01m). Diamond drill line
by surveyed back sight and foresight pegs.
Dip was checked with clinometer on drill mast
at set up on hole. RC holes are surveyed by
down hole surveys at 30m intervals using
single shot “Reflex Camera +/- 0.10 by drill
contractor.
Diamond holes are surveyed by down hole
surveys at 30m intervals using single shot
“Reflex Camera +/- 0.10 by drill contractor.
All holes are surveyed for deviation at end of
hole by gyroscope method by drilling
contractor using a hired Reflex gyro. This is
normally inside rods but may be open hole
for RC drilling.
Final hole collar locations surveyed by
licenced surveyor (Minecomp Pty Ltd) DGPS
(0.01m).
Specification of the grid system used. The grid system used is Geocentric Datum of
Australia 1994 (GDA94).
Quality and adequacy of topographic
control.

CRITERIA JORC CODE EXPLANATION COMMENTARY
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 Geocehmistry 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.
Audits or
reviews
The results of any audits or reviews
of sampling techniques and data
No audits or reviews have been undertaken.

Geology Deposit type, geological setting and
style of mineralisation.
The Mulgabbie North Au deposit is an
Archaean mesothermal Au deposit.
The Mulgabbie North local geology
consists of a sequence of ultramafic,
mafic felsic –intermediate volcanic and
volcaniclastic rocks, with interflow
carbonaceous sediments found on the
lithological boundaries. Archean dolerite
intrusions are conformable within the
sequence. The metamorphic grade of
rocks at Mulgabbie North is lower
greenschist facies.
The alteration assemblage associated
with Better Au grades consists of quartz
carbonate and sericite. Pyrite and
arsenopyrite mineralisation is associated
with elevated Au grades at Mulgabbie
North.
Mulgabbie North gold mineralisation is
found within the Relief Shear that occurs
on a lithological contact between
mafic/ultramafic volcanic/intrusives and
Intermediate/felsic volcanic volcanclastics.
This contact represents a major trans
lithospheric structure situated on the
eastern margin of the Carosue Dam
basin.

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
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.
Relationship
between
mineralisation
widths and
intercept
lengths
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°.
The dominant mineralisation geometries
seen at the Mulgabbie North gold project
are;
1. Shear zone hosted mineralisation on
the lithogical contact which strikes
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%
If the geometry of the mineralisation
with respect to the drill hole angle is
known, its nature should be
reported.
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’).

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
