ASX RELEASE

Koongie Park Project: Copper mineralisation discovered at Cosmo prospect, sulphides intersected at Onedin.

Highlights

  • First nine holes of 13-hole reverse circulation (RC) drilling program over 2,418m confirms discovery of significant near-surface copper mineralisation at Cosmo prospect, south-west of the Onedin deposit, within the Koongie Park Project, Western Australia.

  • Assay highlights as follows:

  • ACORC22006 – 9m @ 0.51% Cu, 0.48% Zn and 5g/t Ag from 73m including

3m @ 0.75% Cu, 0.41% Zn and 7g/t Ag from 75m

  • ACORC22007 – 21m @ 0.41% Cu, 1.99% Zn and 2g/t Ag from 106m including

5m @ 0.74% Cu, 2.79% Zn and 4g/t Ag from 115m

  • ACORC22015 – 6m @ 0.61% Cu, 0.88% Zn and 3g/t Ag from 127m and

  • ACORC22016 – 14m @ 0.48% Cu, 0.74% Zn and 5g/t Ag from 154m

  • Cosmo is situated 500m south-west of the main Onedin deposit area but has been largely unexplored. Further drilling planned for this prospect later in 2022.

  • Diamond drilling at the downhole electromagnetic (EM) conductor targets near Onedin has identified a significant zone of sulphide mineralisation at depth that creates potential for an underground development option, subject to further drilling.

AuKing Mining Limited (ASX:AKN) has confirmed significant intersections of near-surface copper, zinc and silver mineralisation at its Cosmo prospect, south-west of the Onedin deposit, at its flagship Koongie Park Copper/Zinc Project in Western Australia’s Halls Creek region.

The first nine holes of the company’s 13-hole RC program over 2,418m at Cosmo discovered mineralisation across different areas of the prospect, creating the potential to establish a significant additional near-surface deposit area that is only 500m to the south-west of the Onedin deposit.

AuKing’s drilling program was focused on certain magnetic anomalies identified in previous magnetic surveying at Cosmo ( see Figure 1 below ).

Despite the proximity to Onedin, the Cosmo area has largely been untested by exploration and drilling activities previously.

AuKing chief executive officer, Mr Paul Williams, said: “The discovery at Cosmo, while still at very early stages of an unexplored system, was very encouraging especially due to its proximity to the existing Onedin deposit and its potential to add more resource tonnes to Koongie Park, which hosts a JORC compliant mineral resources of 8.9Mt million tonnes (Mt)[1] .”

Further drilling is now planned at Cosmo before the end of 2022.

Future Cosmo Activities

Based on the results from these initial drillholes at Cosmo, AuKing is planning a further significant RC drilling program be undertaken later this year. The intention of this program is to gain a better understanding of the geology at Cosmo and focus on the areas of the prospect where the mineralisation is likely concentrated. There are also plans to carry out downhole EM surveys of certain drillholes at Cosmo to further identify mineralized zones at this prospect.

Sulphides at Onedin

Diamond drilling continues to be carried out on certain DHEM conductor sources that were identified by the company’s downhole geophysics activities nearby both Onedin and Sandiego earlier this year. Drilling has now been completed at the two Onedin holes and significant visible disseminated sulphide mineralisation has been detected across a wide zone, which will now be the subject of assaying. AuKing now awaits the results of assays from these intervals over the coming weeks.

This announcement has been authorised by Paul Williams, CEO, AuKing Mining Limited.

About AuKing Mining

AuKing Mining’s (ASX:AKN) flagship Koongie Park Copper Zinc Project in Western Australia’s Halls Creek Region hosts an estimated JORC resource of 8.9 million tonnes and is neighboured by several significant mining and development operations including Nicholson’s Gold Mine, Panton PGM Project, and Savannah Nickel Mine. AuKing has secured a 75% ownership of the Koongie Park Project, acquiring this interest under the terms of the Joint Venture with Astral Resources (ASX:AAR). Prior to that, Astral held full ownership of the project since 2003. The tenure holding comprises an area of more than 500km[2] covering over 40km of the base metals prospective Koongie Park Formation. Koongie Park has already been the subject of significant exploration drilling and analysis since the 1970’s, often in line with movements in commodity prices. Since its discovery Koongie Park has been the subject of over 300 RC and diamond drill holes consisting of more than 60,000m of drilling in total. The predominant focus of drilling has been at the Sandiego and Onedin deposits, the latter of which offers the potential to establish an open pit mine.

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.
• Include reference to measures taken to ensure sample
representivity and the appropriate calibration of any measurement
tools or systems used.
• Aspects of the determination of mineralisation that are Material to
the Public Report.
• 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
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.

Reverse Circulation (RC) drilling at Cosmo was used to obtain
individual 1 m samples, which were reduced in size to produce a
sample of approximately 1–2 kg in weight, The samples were
ticketed prior to dispatch to the analytical laboratory and then
pulverised to produce a pulp sample for fire assay and base metal
analyses.

The RC drilling results reviewed in the accompanying release were
obtained entirely by RC drilling with the sample return reporting
to a cyclone and cone splitter. Sampling has been done on a single
metre by metre basis.
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).

No previous drilling has been undertaken at the Cosmo Prospect.
RC drilling using a face sampling hammer was undertaken to
obtain samples for the programme under review.

The Competent Person considers the RC drilling technique to be

Analytical work on the samples from the RC sampling programme
reviewed in this release has been undertaken by Bureau Veritas
Minerals Pty Ltd (BV), Canning Vale, Perth, WA.

RC samples are pulverised to a nominal 90% passing 75µm.

A multi-element suite is assayed for using a mixed acid digest on
a 0.15gm charge that involves the use of nitric, perchloric and
hydrofluoric acids in the attack. Dissolution is then achieved using
hydrochloric acid. The use of hydrofluoric acid ensures the
breakdown of silicate minerals. Although the digest approaches

total dissolution of the sample there can be undissolved material
encountered. Analyses are performed via ICP-OES to a range of
detection limits.

The following elements are currently being analysed for
(detection limits in parentheses, as ppm unless otherwise
indicated): Ag (0.5); Al (0.01%); As (1); Ba (1); Be (0.5); Bi (0.1); Ca
(0.01%); Cd (0.5); Ce (0.1); Co (1); Cr (10); Cu (1); Fe (0.01%); Ga

Te (0.2); Th (0.1); Ti (50); V (5); Y (0.1); Zn (2) and Zr (1).

The balance of the pulp sample is stored pending additional
analytical work being required.

Routine Au analyses by 40gm charge fire assay are also
undertaken at BV’s Canning Vale laboratory.

The laboratory includes a number of blanks and internal CRMs on
an approximately 1 in 25 basis as internal QAQC checks. These
results are also reported.

The results seen to date indicate that there are no concerns with
the quality of analyses reported.

The Competent Person considers that the level of QAQC being
applied gives confidence in the accuracy and precision of the
results being received form BV.
Verification of
sampling and
assaying
• The verification of significant intersections by either independent
or alternative company personnel.
• The use of twinned holes.
• Documentation of primary data, data entry procedures, data
verification, data storage (physical and electronic) protocols.
• Discuss any adjustment to assay data.

The grade of significant intersections has been verified by other
senior geological personnel associated with the project.

Twinned drilling has not yet been undertaken.

The drilling database is currently managed by Newexco
Exploration, a Perth based exploration consultancy group. All
drilling data resides on their NXDB database management system.
Newexco is responsible for uploading all analytical and other
drilling data and producing audited downloaded data for use in
various miningsoftwarepackages. The NXDB system has stringent
data entry validation routines.

AKN is proposing to undertake check analytical work on a number
of key mineralised intersections at a second commercial
laboratory in due course.

No adjustments have been made to any of the received analytical
data.
Location of data
points
• Accuracy and quality of surveys used to locate drill holes (collar and
down-hole surveys), trenches, mine workings and other locations
used in Mineral Resource estimation.
• Specification of the grid system used.
• Quality and adequacy of topographic control.

Early (pre-AKN) exploration work at Cosmo by previous workers
utilised a regional grid. Detailed survey work has previously cross-
referenced the local grid to the Zone 52 MGA coordinate system
and GDA 2020 coordinate systems.

A digital elevation model gives adequate control in respect of
elevation data.

Proposed drill hole locations were set out for the current
programme using GDA 2020 co-ordinates.

A DGPS survey of drill hole collars will be completed at the
conclusion of the current drill programme.

Set-up collar azimuths and inclinations have been established
using a compass and clinometer.

The current RC drillholes have been surveyed by north-seeking
gyroscopic method.
Data spacing
and distribution
• Data spacing for reporting of Exploration Results.
• 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.
• Whether sample compositing has been applied.
• Drillhole spacing at Cosmo is very broad in line with the
exploratory nature of the drilling, approximately 100-200m.
• The current drilling programme at Cosmo represents an initial test
of a number of magnetic features. The data spacing is not
sufficient to allow a Mineral Resource classification to be applied.
• All intervals reported are length weighted composites.
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.
• If the relationshipbetween the drillingorientation and the

The orientation of the current (and previous) drillholes at Cosmo
is orthogonal to the perceived strike of mineralisation and limits
the amount of geological bias in drill sampling as much as
orientation of key mineralised structures is considered to have

possible.
Sample security
• The measures taken to ensure sample security.

All samples were placed in large poly-weave bags for road
transportation to the analytical laboratory in Perth by a local
transportation service.

The Competent Person considers the security of sample data
through the sampling and analytical processes to be adequate to
support the public release of drill results.
Audits or
reviews
• The results of any audits or reviews of sampling techniques and
data.

No audits or reviews have yet been carried out for the current drill
sampling programme other than internal check reviews.

The Competent Person considers that an adequate level of QAQC
is currently being undertaken.

The Cosmo prospect (previously Onedin South) is located within M80/277, the
Onedin mining lease. The prospect is located 17km southwest of Halls Creek
township, close to the Great Northern Highway and 1km southwest of AKN’s
Onedin Project.

The tenement is in good standing and part of AKN’s Koongie Park joint venture with
Astral Resources (ASX: AAR).

AKN’s joint venture with AAR in respect of the group of tenures called ‘Koongie
Park’ commenced in June 2021. The primary mineral assets, the Onedin and
Sandiego copper-zinc-gold-silver deposits lie within the granted mining leases
M80/277 and M80/276 respectively. These tenures expire in 2031.

Both mining licences M80/277 and M80/276 were granted in 1989 and therefore
prior to the Native Title Act 1993 (“NTA”). The Koongie-Elvire Native Title Claim WC
1999/040 was also registered aftergrant of the mininglicences and theyare not
subject to the future act provisions under the NTA.
Exploration done by
other parties
• Acknowledgment and appraisal of
exploration by other parties.

Numerous companies have explored within the tenement area, primarily focusing
on the discovery of a significant stratabound lead-zinc system with volcanogenic
affinities.

All exploration is considered to have been completed to a reasonable standard by
experienced companies in a professional manner. Most exploration work has been
appropriate but there are minor issues with inadequate historic documentation.

The Koongie Park project area has been explored for base and precious metals on
an intermittent basis since 1972.

1972–1977 - Kennecott pegged tenements over known copper-lead-zinc-silver
gossans as part of its Gordon Downs 3 project. Work included geological and
structural mapping, rock chip and soil sampling, diamond and percussion drilling.
This work outlined significant base metal mineralisation hosted by chert, banded
iron formations and carbonate-rich assemblages at Onedin, Sandiego, Hanging Tree
and Gosford.

1972–1977 - Kennecott pegged tenements over known copper-lead-zinc-silver
gossans as part of its Gordon Downs 3 project. Work included geological and
structural mapping, rock chip and soil sampling, diamond and percussion drilling.
This work outlined significant base metal mineralisation hosted by chert, banded
iron formations and carbonate-rich assemblages at Onedin, Sandiego, Hanging Tree
and Gosford. Drilling immediately followed at these four prospects, with 29 RC
holes with diamond tails, with the most significant deposit defined from this work
at Sandiego.

1978–1979 - Newmont continued testing the known mineralisation, using
extensive trenching, percussion and diamond drilling, detailed geophysics including
ground magnetic surveys and low-level aeromagnetic surveys, which failed to
locate significant extensions of the mineralisation in the known prospects.

1980 - North Broken Hill concentrated on testing the supergene enriched zone at
the base at the Sandiego prospect.

1983–1988 - Asarco Australia Ltd carried out RAB drilling in the Mimosa sub-
member, along strike of the known mineralisation, locating several significant
geochemical anomalies,although not of sufficientgrade to support a Mineral

Resource estimate. The drilling was to fixed depth and only the bottom of the hole was sampled.

  • Asarco also completed limited work on the supergene gold and base metal potential at Sandiego. This work indicated a resource at Sandiego of 0.33 Mt of supergene ore at 6.7% Cu and 288 g/t Ag and 4.3 Mt of primary ore grading 0.5% Cu, 0.8% Pb, 7.9% Zn and 31 g/t Ag.

  • 1988–1989 - BP Minerals and RTZ Mining went into a joint venture (JV) with Asarco and continued testing the gold potential by re-assaying split core samples for gold, which did not identify any significant base metal mineralisation. RTZ Mining sold the property to AAR in 1989.

  • 1989–1994 - Billiton Australia and AAR identified extensions of known mineralisation at Onedin. Billiton carried out a broad-based exploration programme including limited RC and diamond drilling. A grade-tonnage estimate for the Onedin prospect was prepared, for 1 Mt @ 11% Zn, 1% Cu and 1% Pb.

  • 1995–2002 - Lachlan Resources and AAR concentrated on identifying shallow resources at Sandiego and Onedin with percussion and diamond drilling programmes. Two polygonal Mineral Resources were estimated for Sandiego in 1996 and 1997.

  • AAR was sole tenure holder of the properties between 2002 and 2020. AAR drilled 245 RC and diamond drillholes encompassing 50,417 m, focusing on Mineral Resource, metallurgical and geotechnical drilling at the Sandiego and Onedin base metal deposits. Since 2011, AAR has focused on gold exploration, with little exploration for base metals occurring on the property. AAR reported Mineral Resources for Onedin in 2006, 2008 and 2009.

  • The Competent Person considers the historical work undertaken incrementally over time has built up a useful understanding of the geological characteristics of the deposit, and all historical work provides useful information.

  • AKN’s Joint Venture Agreement with AAR commenced in June 2021 and AKN assumed management and control of the exploration activities on the property. Drilling commenced in June 2022. New results reported above and supported by this Table are based on work solely undertaken by AKN.

Geology
• Deposit type, geological setting, and style
of mineralisation.

The Cosmo base metal occurrence within the M80/277 tenement area is hosted by
metamorphosed volcanics and volcaniclastic sediments of the Koongie Park
Formation (KPF).

Rocks of the Koongie Park property are assigned to the Lamboo Province, of
Palaeoproterozoic age (1910–1805 Ma), which formed within the northeast
trending Halls Creek Orogen.

The KPF hosts several other base metal occurrences and two significant nearby
base metal deposits, Onedin and Sandiego. The mineralisation at the newly
recognised Cosmo Prospect displays a similar suite of metals to that at nearby
Onedin (Cu/Zn +/- Pb/Ag/Au)

The massive Cu-Zn dominated sulphide deposits of Koongie Park have been
traditionally classified as volcanogenic massive sulphide (VMS) deposits. A PhD
study concluded in 2002 proposed that the best model for the base metal
occurrence is as a sub-horizontal basin floor replacement VMS. CSA Global concurs
and considers the weight of evidence supports their interpretation as VMS
deposits. Thus, the deposits are interpreted to have been formed around the time
of deposition of the host volcanic and sedimentary strata in which they are bound
and generally in bedding parallel lenses. Hydrothermal fluids associated with
volcanic activity are interpreted to have been the source of the metals and other
constituents of the mineralisation.
Drill hole Information
• A summary of all information material to
the understanding of the exploration
results including a tabulation of the
following information for all Material drill
holes:
o easting and northing of the drill hole
collar
o elevation or RL (Reduced Level –
elevation above sea level in metres) of
the drill hole collar
o dip and azimuth of the hole
o down hole length and interception
depth
o hole length.

All requisite drill hole information is included in Appendix A of this report.

The reported intersections are listed in the body of this report.
• If the exclusion of this information is
justified on the basis that the information
is not Material and this exclusion does not
detract from the understanding of the
report, the Competent Person should
clearlyexplain whythis is the case.
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.
• 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.

Intersection calculations are weighted by sample length.

The Cosmo samples are RC chips with a constant sample length of 1m.

Reported intersections are primarily based on a cut-off grade of 0.20% Cu with
selected higher-grade intervals shown at a 0.5% Cu cut-off grade. Selected
intervals at a 2% Zn cut-off grade are also reported.

A maximum of 2m of sub-grade (below cut-off) material is incorporated into
the reported composited intersections

No top cutting of data or grades was undertaken in the reporting of these
results.

Appropriate rounding of results has been applied.
Relationship between
mineralisation widths
and intercept lengths
• 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 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’).

The orientation of the drillholes is generally orthogonal to the strike of
mineralisation and limits the amount of bias in drill sampling as much as
possible.

The Competent Person considers the orientation of drillholes with respect to
the attitude of the lithologies and/or structures hosting mineralisation will be
sufficient to support the reporting of a Mineral Resource estimate in due
course.
Diagrams
• Appropriate maps and sections (with
scales) and tabulations of intercepts should
be included for any significant discovery

collar locations and appropriate sectional
views.
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.
• All significant results received to date are reported in this release.
• All results reported by AKN are considered to be accurate and reflective of the
mineralised system being drill tested.
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.
• This report relates to the results of RC drilling undertaken at the Cosmo
Prospect in May-June 2022.
• AKN believes that the results and data provided herein add further meaning
and understanding to the geological lithologies and structure being tested at
Cosmo.
Further work
• The nature and scale of planned further
work (e.g., tests for lateral extensions or
depth extensions or large-scale step-out
drilling).
• Diagrams clearly highlighting the areas of
possible extensions, including the main
geological interpretations and future
drilling areas, provided this information is
not commerciallysensitive.

AKN’s future exploration at Cosmo will involve a further RC drilling program to
be undertaken later this year. The intention of this program will be to gain a
better understanding of the geology at Cosmo and focus on the areas of the
prospect where the mineralisation is likely concentrated.

There are also plans to carry out downhole EM surveys of certain drillholes at
Cosmo to further identify mineralized zones at this prospect.
