- 7,500m combined RC and diamond drill program ~ 50% complete. Drilling to continue into late November, with ongoing assays reported until the end of year.
September 2021 Quarterly Activities Report 19 October 2021
The activities of AuKing Mining Limited ( “AKN ” and “ the Company ”) during the three month period to 30 September 2021 are highlighted as follows:
1. Commencement of drilling at Koongie Park
Koongie Park drilling program
AKN commenced its drilling program at the Koongie Park copper/zinc project in later July 2021 and made excellent progress during the September Quarter. Approximately 3,500m of a combined reverse circulation (RC) and diamond drilling have been drilled. The initial focus of drilling was to secure suitable water bore sites for both the Onedin and Sandiego deposit areas. This was followed by the drilling of several RC drill holes and the current focus is now on the deeper diamond drilling operations that are operating on a 24-hour basis. (See photo below of diamond drilling activities at Sandiego).
==> picture [464 x 234] intentionally omitted <==
The program is expected to continue for another two months into late November/early December, depending on weather conditions. The ongoing drilling program will provide a steady flow of information for the remainder of CY2021.
The drilling program has the following objectives:
-
Infill drilling at the highly prospective Onedin and Sandiego deposits to improve geological interpretation and resource confidence;
-
Test potential mineralised extensions, especially at depth;
-
Obtain fresh samples for further metallurgical testwork – especially from the near-surface oxide and transition ores at Onedin;
-
Enhance confidence and geological understanding of the extensive amount of previous drilling and exploration data;
-
Obtain other technical data including geotechnical information and density data; and

- Equip most drill holes for follow-up downhole geophysics to assist in identifying possible off-hole conductors for future drill hole targeting.
Initial results overview
Significant Results can be seen below with full results included in the ASX Announcement ‘AuKing intersects 124m of 1.03% Cu at Koongie Park’ of 4 October 2021.

Hole AOWB003
124m @ 1.03% Cu, 1.08% Zn, 1.54% Pb & 50g/t Ag from 8m including: 23m @ 0.72% Cu, 1.24% Zn, 0.96% Pb & 1g/t Ag from 25m

Figure 2 – Onedin Cross-section 20040N (hole AOWB003)
This hole was drilled as a proposed water bore hole using RC drilling but was sampled due to its proximity to previously intersected mineralised zones. The results show a 124m continuous near-surface, high-grade zone of > 1% grade copper, lead and zinc mineralisation. Other key features include:
- High grade zones of silver mineralisation;
Page 4
September 2021 Quarterly Activities Report 19 October 2021
-
High-grade zone of molybdenum (Mo) towards the lower end of the hole, despite limited evidence of Mo being assayed from previous activities at Onedin. This result will require further assessment and consideration; and
-
Hole was terminated at 132m for water bore purposes, but assays indicate significant mineralisation at the end of hole. As a result, existing drill hole AORC005 will be extended by a further 170m in order to attempt to intersect an extension of the mineralisation at further depth.

Figure 4 – Onedin Cross-section 19990N (hole AORC002)
Similar to AORC001, this hole was also directed towards infilling the existing drilling pattern and closing off mineralisation on the eastern edge of the Onedin deposit. As was the case with AORC001, the results for this hole demonstrated that the zone is still significantly mineralised and thereby not closed off. Furthermore, AKN will extend this drillhole by a further 60m with the diamond drilling rig over the coming weeks to test the mineralization at depth.

deposit. However, the continuous mineralised zone on the eastern edge demonstrates that this previously defined eastern edge at Onedin remains open and will require further investigation and drilling.

Figure 6 – Onedin Cross-section 20070N (hole AORC004)
Being located in the upper-central zone of known mineralisation at Onedin, hole AORC004 was designed mostly for infill drilling and resource definition purposes. Identifying a

continuous near-surface zone of mineralisation of more than 120m was beyond expectations but completes the objectives for this hole. The hole also confirms the significant zone of Mo that was intersected at the nearby water bore hole AOWB003.
Initial results summary
The results from AKN’s first five drill holes have exceeded expectations. Highlights include:
-
Substantial continuously-mineralised intersections of more than 120m with two holes and nearly 100m in a third;
-
All holes indicating near-surface mineralization, with one hole assaying minerals from surface;
-
High grades of copper, zinc, lead and silver identified across all holes;
-
A high-grade zone of molybdenum identified in holes AORC004/AOWB003 at 120m; and
-
The eastern edge of the Onedin deposit (based on earlier drilling) is still in mineralization and by no means closed off.
These results provide important information that will be incorporated into AKN’s existing understanding of the Onedin resource. With further drilling scheduled for Onedin over the coming months, AKN expects to provide additional information that will be complementary to the results reported above.
2. Significant cobalt intersections identified at Koongie Park
In the course of the preparatory work associated with the proposed metallurgical testwork program, AKN recognised significant zones of cobalt mineralisation that were intersected by drilling carried out more than 10 years ago. All of the identified cobalt intersections are found in previously reported drill holes at the Sandiego deposit. It should be noted however, that no drill holes prior to 2009/2010 were assayed for cobalt, leaving a significant number of those previous holes open to being re-assayed to identify the extent of cobalt present in the mineralisation. Significant intervals include:
Hole SRCD059
19.9m @ 1.3% Cu, 19.9% Zn, 0.17g/t Au, 129g/t Ag & 0.09% Co from 168.1m including 2.9m @ 3.42% Cu, 15.61% Zn, 0.4g/t Au, 200g/t Ag and 0.33% Co from 168.1m
Hole SRCD063
6.0m @ 3.68% Cu, 0.50g/t Au, 10g/t Ag & 0.10% Co from 291m
Hole SRCD064
14.52m @ 7.33% Cu, 0.8g/t Au & 0.34% Co from 393.73m including 9.6m @ 9.7% Cu, 1.10g/t Au & 0.49% Co from 394.5m and 3.0m @ 11.64% Cu, 1.08g/t Au & 0.96% Co from 399m

Hole SRC061
73m @ 4.8% Cu, 7.3% Zn, 2.1% Pb, 70g/t Ag & 0.06% Co from 101m including 17m @ 8.8% Cu, 1.7% Zn, 4.1% Pb, 198g/t Ag, 0.18g/t Au and 0.25% Co from 101m and 7m @ 5.75% Cu, 0.65g/t Au, 11.95% Zn, 36g/t Ag & 0.13% Co from 134m
Hole SRC062
19m @ 0.77% Cu, 5.64% Zn, 62g/t Ag & 0.11% Co from 130m
[See AAR ASX release 23 July 2010 (Holes SRC060, 061 and 062) and release 30 August 2010 (Holes SRCD059, SRCD063 and SRCD064)]
Previously unreported cobalt intersections from older AAR drill holes identified during the recent analysis by AKN include:
Hole SRCD028A
9m @ 4.19% Cu, 0.38g/t Au, 50g/t Ag & 0.13% Co from 270m
Hole SRCD030
16m @ 4.10% Cu, 1.71g/t Au, 12.04% Zn, 118g/t Ag & 0.11% Co from 208m including 2m @ 2.70% Cu, 0.65g/t Au, 3.60% Zn, 53g/t Ag & 0.31% Co from 219m and 3m @ 1.51% Cu, 1.19g/t Au, 9.53% Zn, 461g/t Ag & 0.28% Co from 232m
Hole SRCD031
35m @ 7.82% Cu, 2.15% Pb, 12.12% Zn, 139g/t Ag & 0.12% Co from 100m including 21m @ 12.40% Cu, 1.35% Pb, 6.80% Zn, 119g/t Ag & 0.18% Co from 100m and 21m @ 7.87% Cu & 0.10% Co from 148m
A close spatial correlation is noted between the high-grade copper mineralisation and the associated cobalt assays, suggesting a genetic relationship. Although a number of the highergrade cobalt intersections are located within the transitional zone, there is no suggestion that the cobalt concentration reflects any kind of supergene enrichment. The true distribution of cobalt in the Sandiego mineralised zone remains unclear due to the absence of cobalt assays in much of the early drilling. Drill collar details (historic cobalt intersections at Sandiego) are included in Appendix 3 and the JORC Table 1 for those results is attached to this Report.
The existence of significant grades of cobalt mineralisation at Sandiego has added a further dimension to the scope of a potential future mining operation at this deposit. This is now possible as a result of the contemporary focus on a high cobalt price and the application of this mineral in the “battery metals” sector – something that was not the case when the above drilling results were originally published. Previous feasibility studies also focussed only on the development of an underground mine at Sandiego. In the event of AKN confirming a significant presence of cobalt within the mineralisation that is nearer to surface, the possible introduction of an open pit operation at Sandiego can be considered.
Page 10
September 2021 Quarterly Activities Report 19 October 2021
AKN intends to factor into its future drilling plans at Koongie Park provision to assess the extent of the near-surface mineralisation (including cobalt) at Sandiego.

3. Koongie Park Summary
Koongie Park copper/zinc project overview
Koongie Park is situated in north-eastern Western Australia in the highly mineralised Halls Creek region. The Koongie Park project comprises 10 licences (two mining and eight
Page 11
September 2021 Quarterly Activities Report 19 October 2021
exploration) covering an area of over 500km[2] . The asset has existing JORC 2012 resources of 6.8Mt at 1.3% Cu, 4.1% Zn, 0.3g/t Au and 26g/t Ag* .
[* See full resources table in Appendix 2 of this Release and CSA Global Independent Report, AKN Prospectus dated 9 March 2021 ]
Koongie Park remains significantly under explored at depth and along strike and highly prospective for further VMS base metal mineralisation discoveries in the tenement package. The Company has identified multiple drill targets to expand on the existing known resources at both the Sandiego and Onedin deposits. Both deposits remain open at depth and to the south.
Koongie Park Earn-in
In February 2021, AKN entered into an earn-in and joint venture agreement (“JVA”) with Anglo Australian Resources NL (ASX: AAR) providing AKN with the right to earn up to a 75% interest in the Koongie Park project by completing exploration expenditure of $3m over a 3- year period. This expenditure is in addition to the $1m already paid by AKN to secure an initial 25% interest in the JV. The JVA commenced on 15 June 2021 upon AKN’s re-quotation on the ASX.
4. New Licence Application – Tanami Region, WA (“Blondie”)
During the Quarter, AKN lodged an application to the WA DMIRS for the grant of a 20km[2] exploration licence in the Tanami region on the WA/NT border, approximately 190km southeast of Halls Creek and 50kms north of the former Coyote gold mine. The prospect is called “Blondie” and comprises a broad, irregular zone of anomalous copper geochemistry covering an area of approximately 1 km x 1 km. The anomaly coincides with an area of patchy outcrop/subcrop of suspected Stubbins Formation of the Paleo-Proterozoic Tanami Group. Previous exploration in the region has been mostly focussed on identifying gold occurrences.
Steps will be taken by the Company to secure grant of this new exploration licence in the near future, prior to establishing an initial exploration program for the area.
5. ASX Compliance and Disclosures
Exploration Activities (ASX LR 5.3.1)
AKN conducted significant exploration activities during the Quarter with both RC and diamond drilling contractors engaged throughout the period. Total exploration expenditure for the June Quarter was $1,296,000.
Mine Production Activities (ASX LR 5.3.2)
There were no mine production or development activities conducted during the Quarter.
Comparison of Expenditure (ASX LR 5.3.4)
AKN successfully re-listed on the ASX on 15 June 2021. Set out below is a comparison of actual expenditure since reinstatement to ASX Official Quotation against the Proposed Use
Page 12
September 2021 Quarterly Activities Report 19 October 2021
of Funds as set out in the Company’s Prospectus dated 9 March 2021, together with an explanation of any material variances.
| Use of Funds | Estimate for first 2 years after ASX Re-listing |
Actual expenditure post reinstatement on 15 June 2021 |
|---|---|---|
| Initial Koongie Park payment | $900,000 | $900,000 |
| Drilling, metallurgical testwork and other exploration |
$2,250,000 | $1,467,471 |
| Admin costs and other expenses | $900,000 | $482,932 |
| Employment and Consultant costs | $800,000 | $247,561 |
| Repayment of Tighe Loan | $150,000 | $150,000 |
| Brokerage fees associated with public offer |
$600,000 | $600,402 |
| Public offer costs (excl brokerage) | $400,000 | $496,421 |
| Total Expenditure | $6,000,000 | $4,344,788 |
AKN is significantly exceeding its initial project budget expenditure associated with exploration activities at Koongie Park due to several factors, including the following:
-
(a) (as advised previously), due to AKN raising an additional $1M in subscriptions under the 9 March 2021 prospectus, a more aggressive approach was taken towards the size and scope of the current drilling program;
-
(b) There is extensive demand for exploration contractors (drilling, excavation and assaying in particular) in the WA resources sector – resulting in very tight availability for these firms and the necessity to accept commercial terms in order to have work undertaken;
-
(c) Similarly, demand for experienced geological and exploration personnel is very high - due not only to the busy WA resources sector, but also limitations on personnel being able to access WA due to ongoing border and travel restrictions. This demand has created a very competitive market for these personnel and impacted commercial rates accordingly; and
-
(d) Halls Creek, while situated on the National Highway, is still remote from the perspective of securing and transporting consumables for exploration activities – adding costs that were not initially contemplated in the program budget process.

| Exploration | • Acknowledgment and appraisal of exploration by other parties. | The Koongie Park project area has been explored for base and precious |

| parties | pegged tenements over known copper-lead-zinc 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. During 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. In 1980, North Broken Hill | ||
| concentrated on testing the supergene enriched zone at the base at | ||
| Sandiego. In 1983–1988, Asarco Australia Ltd carried out rotary air blast | ||
| (RAB) drilling in the Mimosa sub-member, along strike of the known | ||
| mineralisation, locating several significant geochemical anomalies, | ||
| although not of sufficient grade 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. | ||
| Limited testing was undertaken for gold in the sulphide deposits. In | ||
| 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. In 1989– | ||
| 1994, Billiton Australia and AAR identified extensions of known | ||
| mineralisation at Onedin. Billiton carried out a broad-based exploration | ||
| program 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. | ||
| In 1995–2002, Lachlan Resources and AAR concentrated on identifying | ||
| shallow resources at Sandiego and Onedin with percussion and diamond | ||

| Geology | • Deposit type, geological setting and style of mineralisation. | Rocks of the Koongie Park property are assigned to the Lamboo |
| Province, of Palaeoproterozoic age (1910–1805 Ma), which formed | ||
| within the northwest trending Halls Creek Orogen. The Central Zone of | ||
| the Lamboo Province comprises turbiditic metasedimentary and mafic | ||
| volcanic and volcaniclastic rocks of the Tickalara Metamorphics, | ||
| deposited by 1865 Ma. These rocks were intruded by tonalitic sheets and | ||
| deformed and metamorphosed between 1865–1856 Ma and 1850– 1845 | ||
| Ma. A younger succession of rocks comprising the sedimentary rocks | ||
| and mafic and felsic volcanic rocks of the Koongie Park Formation (KPF) | ||
| were deposited in a possible rifted arc setting at around 1843 Ma. | ||
| Layered mafic–ultramafic bodies were intruded into the Central Zone at | ||
| 1856 Ma, 1845 Ma and 1830 Ma. Large volumes of granite and gabbro | ||
| of the Sally Downs Supersuite intruded the Central Zone during the Halls | ||
| Creek Orogeny at 1835–1805 Ma. Researchers interpret the Central | ||
| Zone to be an arc-like domain developed on a continental fragment. The | ||
| KPF within the Koongie Park property is broadly characterised as | ||
| metamorphosed low-grade composed of mafic and felsic volcanic and | ||
| associated sedimentary facies including sandstone, mudstone, | ||
| carbonate, chert and ironstone intruded by rhyolitic to rhyodacitic sills, | ||
| dolerite bodies and basalt dykes. The KPF hosts numerous base metal | ||
| occurrences and two significant base metal deposits. The upper unit of | ||
| the KPF composes felsic volcanic units, carbonate, ironstone, chert, | ||
| mudstone, quartz-bearing volcaniclastic beds and lithic sandstone. | ||
| Currently known base metal prospects are concentrated in the upper | ||
| KPF at Koongie Park (i.e. the trend which includes Sandiego and Onedin | ||
| deposits). Both the Sandiego and Onedin deposits are situated within the | ||
| limbs of intensely folded, higher order, double-plunging anticlinal | ||
| structures that have been interpreted from magnetic images. The axial | ||
| planes of the fold structures appear to be upright to south-southeast | ||
| dipping. They trend northeast, sub-parallel to the regional transcurrent | ||
| and anastomosingfault systems that dominate the Halls Creek Orogen. |

| The massive 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 is | ||
| interpreted to have been the source of the metals and other constituents | ||
| of the mineralisation. The mineralogy of the primary mineralisation at | ||
| Sandiego is pyrite-sphalerite-pyrrhotite-chalcopyrite ± galena which is | ||
| largely hosted in the magnetite-rich exhalative suite of rocks where it | ||
| occurs as a massive conformable wedge-shaped lens 200 m in length | ||
| with a maximum thickness of 75 m. Weak to moderate sulphide vein and | ||
| stringer mineralisation occur at the base of the exhalite package in the | ||
| underlying tuffs. Mineralisation is relatively rare in the carbonate zone but | ||
| may extend into the talc-chlorite schists. Overall, there is poor spatial | ||
| correlation between copper and zinc mineralisation at Sandiego. | ||
| Moreover, discrete zinc-rich and copper-rich zones have been identified | ||
| from core logging and assay results in the vertical dimension (Elliott et | ||
| al., 2006). Supergene mineralisation at Sandiego is poorly developed | ||
| although a supergene copper Mineral Resource is reported. The KPF | ||
| exhibits a deep weathered profile at Sandiego, resulting in three | ||
| weathering domains – oxidised zone at surface, primary zone at depth, | ||
| and the transition zone in between. Each zone has very different mineral | ||
| assemblages and consequently very different metallurgical properties. | ||
| Supergene mineralisation at Sandiego is well developed although the | ||
| bulk of the deposit located in the transition and primary zones. Significant | ||
| supergene enrichment of copper has occurred with a range of secondary | ||
| copper minerals present: malachite, chrysocolla, bornite, covellite, | ||
| chalcocite, cuprite, digenite and native copper. Localised occurrences of | ||
| secondary zinc are also present in the form of smithsonite; however, zinc | ||
| is generally depleted in the oxide zone. | ||
