ASX Announcement

29 March 2021

Widespread High-Grade Gold Aircore Results

OzAurum Resources Ltd ( ASX: OZM or OzAurum or the Company ) is pleased to announce additional Aircore (AC) drilling results from 102 holes for 7,284 meters (m) of drilling at its Mulgabbie North Project situated two kilometres from the Northern Star Resources (ASX: NST) Carosue Dam Operations – about 1.5 million ounces gold production to date.

Highlights

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

  • 8m @ 4.28 g/t gold (Au) from 24m - MNOAC 120

  • 4m @ 2.05 g/t Au from 24m - MNOAC 100

  • 4m @ 1.96 g/t Au from 28m - MNOAC 083

  • 8m @ 1.52 g/t Au from 36m - MNOAC 083

  • 4m @ 1.24 g/t from 44m - MNOAC 096

  • 3m @ 1.34 g/t from 72m - MNOAC 115

  • New 400m long, and up to 150 wide, gold zone intersected west of current Mulgabbie North RC drilling on the Relief Shear with widespread gold mineralisation.

  • New gold zone potentially represents the near surface footprint of significant primary gold mineralisation.

  • Multiple zones defined by numerous AC drill holes intersected significant gold mineralisation at end of hole (EOH), with RC drilling starting immediately to test these zones.

  • The 40-80m wide zone of Hematite alteration at Mulgabbie North intersected in the bottom of hole AC samples currently extend for 1.2 km along strike, and 150m west of current RC drilling on the Relief Shear. Hematite is a key signature of the adjacent Northern Star Carosue Dam Karari and Whirling Dervish Gold Mines- where about 1.5 million ounces gold have been produced to date.

Mulgabbie North AC Drilling Results

The 102 AC holes drilled for 7,284m form part of OzAurum’s initial 30,000m AC drilling campaign which began in February this year.

A new 400m long, and up to 150m wide, of widespread gold mineralisation has been intersected by AC drilling situated west of RC drilling currently also underway at Mulgabbie North that has so far identified highly prospective intermediate-felsic volcaniclastic host- similar to the adjacent Northern Star Carosue Dam Karari and Whirling Dervish Gold Mines that have produced about 1.5 million ounces of gold. Numerous AC holes have intersected 4m composite results of greater than 1 g/t Au including; 4m @ 1.96 g/t Au from 28m (MNOAC083), 8m @ 1.52 g/t Au from 36m (MNOAC083) and 4m @ 1.24 g/t Au from 44m (MNOAC 096).

A significant AC drilling result of 8m @ 4.28 g/t Au from 24m (MNOAC 120) was also intersected along with 3m @ 1.34 g/t Au from 72m (MNOAC096) situated 350m west of the relief shear. These are exciting new targets that will be followed-up in future RC drilling.

Widespread gold mineralisation at this new 400m long zone is currently open at depth. 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 defining a trend striking NW for approximately 1.2 kms, and situated 150m west of the current Mulgabbie North RC drilling. Hematite alteration is the characteristic alteration of the adjacent Northern Star’s Karari and Whirling Dervish Gold Mines that have produced about 1.5 million ounces of gold to date (as announced on 15 March 2021). 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.

The AC drilling program is being undertaken on a 100m x 40m and 200m x 80m drill spacing. 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 additional high-grade AC intercepts so early on in our large-scale drilling campaign. This is a new widespread zone of gold mineralisation situated west of our current RC drilling at Mulgabbie North 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 1.2km 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.”

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 Deposit – Ben Prospect
102 AC holes (MN0AC 031 - 132 7284m),
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

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

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

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.

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

eastern margin of the Carosue Dam
basin.

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

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.
