ASX Announcement

24 September 2021

New Gold Zone Defined at Mulgabbie’s Alicia Prospect

OzAurum Resources Ltd ( ASX: OZM or OzAurum or the Company ) is pleased to announce further results from the Company’s large-scale 20,000 metre (m) Reverse Circulation (RC) drilling campaign, which has so far identified significant wide zones of gold mineralisation. The current RC results include two holes for 400m of drilling at the Alicia Prospect within the Mulgabbie North Project, located North East of Kalgoorlie.

Highlights

  • Significant new primary gold mineralisation intersected over a wide zone at the Alicia Prospect situated 1km south east of current RC drilling

  • Gold mineralisation is open along strike and at depth

  • RC holes that intersected significant gold mineralisation include:

  • 33m @ 1.24 g/t gold (Au) – (from 93m) including 8m @ 3.29 g/t Au MNORC 109

  • 23m @ 0.92 g/t Au – (from 89m) MNORC 109

  • 6m @ 1.45 g/t Au – (from 83m) MNORC 110

  • New wide zone of primary gold mineralisation extends over 80m of strike along the Relief Shear

  • MNORC 109 + 110 situated 40m grid north and south of historic Gutnick Resources NL RC hole PINC 3 that intersected 24m @ 1.60 g/t from 68m including 1m @ 18.90 g/t Au

  • Host rocks, alteration and mineralisation are identical to Mulgabbie North RC drilling currently situated 1km to the north

  • Drill results confirm the magnitude and continuity of mineralisation over the Relief Shear, including potential for mineralisation at the Alicia Prospect to link with previously intersected gold mineralisation at the Ben Prospect also along the Relief Shear - 1km to the north

  • Planned RC drilling to commence in the coming weeks to scope out the extent of this new mineralisation discovery

  • 12,000m Aircore (AC) program to commence on the 28[th] September to test the 1km gap along strike to the north

Mulgabbie North RC Drilling Results

The current RC results include two holes that were drilled for 400m - 1km south of concurrent RC drilling at the Mulgabbie North Project. The drilling is a continuation of OzAurum’s 20,000m RC drilling campaign that commenced in February this year. To date, a total of 124 RC holes have been drilled at Mulgabbie North for 18,461m.

This RC drill campaign has identified further significant gold mineralisation at the Alicia Prospect within the Mulgabbie North Project. These are the first two holes that have been drilled at the Alicia Prospect by the Company, with both holes intersecting wide zones of gold mineralisation. RC holes MNORC 109 intersected 33m @ 1.24 g/t Au from 93m including 8m @ 3.29 g/t Au and from 135m 6m @ 1.45 g/t Au also MNORC 110 intersected 23m @ 0.92 g/t Au from 89m.

The Alicia Prospect is situated 1km south of concurrent RC drilling at the Ben Prospect. The RC holes at the Alicia Prospect are located 80m apart along strike, both intersecting wide zones of gold mineralisation hosted in altered intermediate-felsic volcaniclastic rocks with pyrite and arsenopyrite mineralisation. This mineralisation is analogous to mineralisation at the Ben Prospect - located 1km to the north. This new gold mineralisation identified is also related to the Relief Shear, similar to the Ben Prospect.

RC drilling at the Alicia Prospect was first undertaken by Gutnick Resources in 1998 and 1999 with only 6 RC holes drilled in the area. Gutnick RC hole PINC3 intersected 24m @ 1.60 g/t Au including 1m @ 18.90 g/t Au . OzAurum RC hole MNORC 109 is situated 40m grid north of PINC3 and MNORC 110 is situated 40m grid south of PINC3.

These 3 RC holes MNORC 109, PINC3 and MNORC 110 have defined a continuous thick zone of gold mineralisation over 80m of strike. This new zone is currently open at depth and along strike at the Alicia Prospect.

The recently completed OzAurum drone magnetometer survey at Mulgabbie North has identified a large demagnetised zone coinciding with the location of these recent RC holes MNORC 109 + 110 and extending into current RC drilling at Mulgabbie North.

The location of RC holes MNORC 109 + 110 at the Alicia Prospect are also situated within a large gravity low trough - very similar to the gravity low trough that hosts the Northern Star (ASX: NST) Carosue Dam corridor of riches that operating gold mines Karari and Whirling Dervish are located.

The current RC drilling at Mulgabbie North has defined primary gold mineralisation for over 1km of strike and we are confident that extensional RC drilling completed will further extend this strike. Also, we believe future RC drilling will identify new primary gold mineralisation related to geochemical gold anomalies and recent AC saprolite hosted gold mineralisation.

These excellent RC results, combined with recently announced aircore (AC) results defining new zones of mineralisation now extending for 2.8 km in strike (see ASX announcement on 2nd September 2021), further highlight the potential of Mulgabbie North to be a significant gold project.

RC drilling at Mulgabbie North has also discovered wide zones of weak to moderate hematite alteration in some RC holes. Specifically, the hematite alteration indicates oxidised fluids from an intrusive complex suggesting proximity to the mineralising centre - likely to be within OzAurum’s 100% owned Mulgabbie North tenure.

Upcoming RC and AC drilling and Planned Exploration Activities:

Follow up RC drilling at Mulgabbie North at the Alicia Prospect will commence in the coming weeks, along with ongoing RC drill testing of AC saprolite gold anomalies and extensions to the Ben and James Prospects.

A 12,000m AC drill program is planned to commence on 28[th] of September to test the drilling gap between the Alicia and Ben Prospects.

Utilising best practice RC drilling, sampling and assay protocols will allow for a potential future JORC 2012 compliant resource to be estimated with confidence at Mulgabbie North.

ASX | 24 September 2021

Due to the current high demand on assay laboratories, the Company is experiencing long delays with receiving assay results, with up to a 10 week turnaround time.

RC drilling is being undertaken on a three week on three week off campaign basis due to long delays in receiving assay results from the assay laboratory.

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

The new wide zones of gold mineralisation intercepted at the Alicia Prospect,1km to the south of current RC drilling at Mulgabbie North, highlights the sheer magnitude of gold mineralisation over the project area. These results, together with previously announced widespread gold mineralisation, further demonstrate the potential of Mulgabbie North to develop into a significant gold project. Additional RC drilling is due to commence in the coming weeks to further test this exciting target at the Alicia Prospect which also coincides with a large zone of demagnetisation and a coincident gravity low trough extending through the Mulgabbie North Project. Aircore drilling will also commence later this month to test the 1.0km gap in drilling between the Alicia and Ben Prospects along the Relief Shear. This is an exciting time for OzAurum, and we believe we are on the right path to making a significant gold discovery.”

The Company will continue to provide regular market updates on exploration activities and report on drilling results as soon as they become available.

instruments, etc). These
examples should not be taken as
limiting the broad meaning of
sampling.
The Mulgabbie North Deposit 2 RC holes
(MNORC 109 - 110 200m), azimuth 220°
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 on average 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 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

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

Measures taken to maximise
sample recovery and ensure
representative nature of the
samples.
Driller’s experience is important. Steady

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,

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.

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 lithological contact which
strikes 315˚ and is moderately
dipping to the east at -75°.
The true width of mineralisation at the

known from existing drilling and all
drilling is designed to intersect the
Relief Shear mineralised envelope at
90° orperpendicular to the strike of
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.

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.

(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

Balanced
reporting
Where comprehensive reporting
of all Exploration Results is not
practicable, representative
reporting of both low and high

practiced to avoid misleading
reporting of Exploration Results.
Please refer to table 1 in the body of
