ASX RELEASE
AuKing significantly increases resources at Koongie Park Project.
Maiden mineral resource estimate reported for Emull Prospect.
Highlights
-
Independent maiden JORC 2012 Inferred and Indicated Mineral Resource Estimate (MRE) for the Emull deposit - 10.8Mt @ 0.28% Cu, 0.44% Zn, 0.1% Pb and 5.4g/t Ag (CuEq 0.51%)
-
Combined with the existing Koongie Park resource estimate of 8.9Mt @ 1.01% Cu, 3.67% Zn, 0.16g/t Au, 32g/t Ag and 0.77% Pb[1] , total metal content now comprises:
-
120,100 tonnes of copper; 373,400 tonnes of zinc; 46,000 ounces of gold; 11 million ounces of silver and 78,700 tonnes of lead.
Auking Mining Limited (ASX:AKN) has significantly increased the overall mineral resources at its flagship Koongie Park Copper/Zinc Project in Western Australia’s Halls Creek region, reporting a maiden mineral resource estimate for the Emull deposit.
AuKing’s total MRE now stands at 19.7 million tonnes (Mt) after a further 10.8Mt were added to the company’s existing 8.9Mt resources at the Sandiego and Onedin deposits to the east. Total metal content now comprises 120,100 tonnes of copper; 373,400 tonnes of zinc; 46,000 ounces of gold; 11 million ounces of silver and 78,700 tonnes of lead.
AuKing chief executive officer, Mr Paul Williams, said the release of Emull’s maiden MRE followed a successful drilling program conducted throughout the year and increases the potential of further significant additional copper resources from planned drilling in 2023.
“We knew that the copper mineralisation at Emull had the potential to offer significant additional tonnes to the Koongie Park resource base, Mr Williams said.
“Emull’s resource tonnes are complementary to Sandiego and Onedin deposits which together provide strong mining development options for Koongie Park.”

Emull Resource Estimate
Emull’s MRE has been classified as an Indicated and Inferred resource and was based upon 99 drill holes totalling 11,051m, comprising 88 historic reverse circulation (RC) drill holes by Northern Star Resources (ASX:NST) between 2003 and 2012 for 9,141m, and 11 RC holes by AuKing during 2022 for 1,910m. Follow-up extensional resource drilling both to the north-west and the south-west will be a key feature of proposed drilling in early 2023 and support an upgrading of the resource classification.
The Emull deposit extends to a depth of 280 vertical metres and is currently modelled with a strike length of approximately 600m, with mineralisation still open at depth and along strike to the northwest. The Emull Mineral Resource is reported at a 0.25% copper equivalent grade and summarised below.

All Mineral Resources figures reported in the table above represent estimates at November 2022. Mineral Resource estimates are not precise calculations, being dependent on the interpretation of limited information on the location, shape and continuity of the occurrence and on the available sampling results. The totals contained in the above table have been rounded to reflect the relative uncertainty of the estimate. Rounding may cause some computational discrepancies.
Mineral Resources are reported in accordance with the Australasian Code for Reporting of Exploration Results, Mineral Resources and Ore Reserves (The Joint Ore Reserves Committee Code – JORC 2012 Edition).
Copper equivalent grades are estimated based on LME closing prices on 25th November 2022 and calculated with the formula: *CuEq =100 x [(Cu% x 8,005) + (Zn% x 2,906) + (Pb% x 2,107) + (Ag g/t x (21.6/31.1035)) ] / (8,005).

About the Emull Prospect Area
The Emull Exploration Licence (E80/4957) is located within the overall Koongie Park tenure package about 19.5km south-west of the Sandiego deposit, and 44kms south-west of the Halls Creek township, along the Great Northern Highway.
The licence forms part of the existing Koongie Park Joint Venture between AuKing and Astral Resources NL, of which AuKing owns an 80% interest.
Since the early 1970’s, several companies have explored within the Emull tenement area, primarily focusing on the potential for a significant stratabound lead-zinc system with volcanogenic affinities. North Star Resources commenced exploration work in the area in E80/2612 in 2003-2004 for a number of target styles including polymetallic mineralisation as seen at Emull, Au mineralisation as identified at the nearby Nicholson’s gold mine and possible PGM mineralisation. North Star undertook extensive drilling in the area with Emull being a strategic focus and concluded exploration activities in the area in 2012 following their Paulsens gold acquisition.

Emull Resource Block Model
A new 3D block model for the Emull deposit was developed by AuKing as part of the resource estimation process. The block model highlights copper mineralisation above 0.2% with the clear potential to expand the deposit along strike and at depth.
==> picture [488 x 226] intentionally omitted <==
Figure 2. Emull Prospect Block Model – looking North
Future Emull Exploration
Having established the maiden MRE for Emull, the focus of future activities at the deposit will be to significantly increase the resource estimate by pursuing copper mineralisation along the magnetic features that exist to the north-west and south-west of the main deposit area. As indicated in Figure 4 below, these targets extend for more than 3kms and are highly prospective areas based on previous soil sampling and historic drilling.
AuKing plans to commence this extensional drilling at Emull after completion of the northern wet season in late March/early April 2023.
Mineral Resource Estimate – ASX Listing Rule 5.8.1
Geology and Geological Interpretation
The Emull base metal deposit occurs in Koongie Park Formation, part of the Palaeoproterozoic Lamboo Province, within the northeast trending Halls Creek Orogen. The deposit is hosted by altered and contact metamorphosed calc-silicate rocks, which have been intruded by and partially assimilated by the Emull gabbro. Thin, semi-massive and disseminated mineralisation is confined to several discontinuous but apparently stratabound lenses, dominated by sphalerite, with subordinate chalcopyrite and galena. The largest lens has a strike length of 500m and a maximum plan width of 50m.
The genesis of mineralisation at Emull is not certain, although models based on an origin as a volcanic hosted massive sulphide (VHMS) deposit partially assimilated during intrusion of gabbro, or as a skarn developed during intrusion of gabbro into carbonate units within the Koongie Park Formation, have been proposed.

Drilling Techniques
Drilling conducted by North Star and AuKing included RC drilling with 5.5 inch hammer and diamond core of HQ and NQ diameter with standard and/or triple tube.
Sampling Techniques
For both historic and recent drilling, mineralisation was sampled with the following techniques: RC drilling - 1m samples of pulverised chips, sampled by a rig mounted cone splitter, with approximately 3kg collected in individual calico bags.
Historical core was sampled at 0.3 to 1.2m intervals, cut in half using a core saw.
Sample Analysis Method
For AuKing drilling, samples were sent to Jinning Testing and Inspection Laboratory in Canning Vale, WA for analysis. A multi-element analytical suite is assayed for using a mixed acid digest on a 20g 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.

==> picture [35 x 32] intentionally omitted <==
The following elements were analysed for (detection limits in parentheses, as ppm unless otherwise indicated): Ag (1); Al (0.01%); As (2); Ba (1); Be (0.5); Bi (5); Ca (0.01%); Cd (1); Ce (5); Co (1); Cr (2); Cu (1); Fe (0.01%); Ga (10); K (0.01%); La (2); Li (1); Mg (0.01%); Mn (1); Mo (2); Na (0.005%); Ni (1); P (20); Pb (2); S (20); Sb (5); Sc (1); Sn (5); Sr (1); Ta (10); Te (10); Th (10); Ti (5); V (1); W (5); Y (1); Zn (1) and Zr (1).
Estimation Methodology
The block model was created and estimated in Surpac using Ordinary Kriging (OK) grade interpolation. The mineralisation was constrained by mineralisation envelopes prepared using a nominal 0.1% copper cut-off grade for disseminated sulphide mineralisation. A minimum down-hole length of 3m was adopted for the interpretation.
Samples were composited to 1m based on an analysis of sample lengths inside the wireframes. Top cuts were applied to some of the zinc and silver composite data after review of the composite statistics.
The block dimensions used in the model were 10m EW by 5m NS by 5m vertical with sub-cells of 2.5m by 1.25m by 1.25m. This was selected as the optimal block size as a result of kriging neighbourhood analysis (KNA).
The block model was created and estimated in Surpac using OK grade interpolation using parameters derived from modelled variograms in up to three passes. Linear grade estimation was deemed suitable for the Emull Mineral Resource due to the geological control on mineralisation.
A bulk density of 2.7t/m[3] was assigned to the fresh material, a value of 2.4t/m[3] was assigned to transition and 2.0t/m3 was assigned to oxide, based on known values from similar geological terrains.
Mineral Resource Classification
The Mineral Resource was classified as Indicated and Inferred Mineral Resource based on data quality, sample spacing, and lode continuity. The Indicated Mineral Resource was defined within areas of close spaced drilling of less than 25m by 20m, and where the continuity and predictability of the mineralised units was reasonable. The Inferred Mineral Resource was assigned to areas where drill hole spacing was greater than 25m by 20m and less than 80m by 80m; where small, isolated pods of mineralisation occur outside the main mineralised zones, and to geologically complex zones.
Cut-Off Grades
A copper equivalent grade (“CuEq”) was calculated based on London Metal Exchange (“LME”) closing prices as at 25th November, 2022. The CuEq formula is shown below: CuEq =100 x [(Cu% x 8,005) + (Zn% x 2,906) + (Pb% x 2,107) + (Ag g/t x (21.6/31.1035))] / (8,005). The Statement of Mineral Resources has been constrained by the mineralisation solids and reported above a copper equivalent cut-off grade of 0.25% under the assumption of an open pit mining method.
Mining and Metallurgical Methods
It is assumed the Emull material can be extracted with open pit mining methods and either toll treating or could be processed as part of a multi deposit operation along with AKN’s Onedin and Sandiego deposits. Metallurgical testwork has not yet been conducted at Emull, although it is anticipated that similar results could be obtained to the geologically similar Onedin and Sandiego

deposits at the project. It is anticipated separate concentrates for copper and zinc could be generated from Emull, however further studies are required.

JORC Code, 2012 Edition – Emull Mineral Resource Estimate Section 1 Sampling Techniques and Data
| Criteria | **JORC Code explanation ** | Commentary |
|---|---|---|
| Sampling techniques |
• Nature and quality of sampling (eg 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 (eg ‘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 (eg submarine nodules) may warrant disclosure of detailed information. |
• Historical drilling methods include aircore, RC and diamond cored drilling. • Aircore, percussion and RC drilling returns a sample of broken rock collected in a bag at site at the time of drilling. Drill core from diamond drilling technique was later cut by a core saw. • AKN utilised Reverse Circulation (“RC”) drilling at Emull to obtain individual 1m samples, which were reduced in size to produce a sample of approximately 1 to 2kg in weight. The samples were ticketed prior to dispatch to the analytical laboratory, 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 connected to a cyclone and cone splitter. Sampling has been done on a single metre by metre basis. |
| Drilling techniques |
• Drill type (eg core, reverse circulation, open-hole hammer, rotary air blast, auger, Bangka, sonic, etc) and details (eg 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). |
• Historical drilling included RC drilling with 5.5 inch hammer and diamond core of HQ and NQ diameter with standard and/or triple tube. • AKN drilling included RC drilling with 5.5 inch hammer. |
| Drill sample recovery |
• Method of recording and assessing core and chip sample recoveries and results assessed. • Measures taken to maximise sample recovery and ensure representative nature of the samples. • 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. |
• AKN RC recovery levels are high hence the relationship between recovery and grade is not an issue. • No relationship between sample recovery and grade has been yet observed and no sample bias is believed to have occurred. |
| 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. • Whether logging is qualitative or quantitative in nature. Core (or costean, channel, etc) photography. • The total length and percentage of the relevant intersections logged. |
• Geological logging of historic drill holes was reviewed by AKN using historic statutory reports and databases compiled by previous operators. • Geological logging data collected to date is sufficiently detailed to support a Mineral Resource at Emull. • For AKN drilling, RC chips were logged for quantitative and qualitative attributes with chips stored in chip trays for future reference. All drill holes were logged in full. |
| Sub- sampling |
• If core, whether cut or sawn and whether quarter, halfor allcore taken. |
• For historical and AKN drilling, mineralisation has been sampled with |
| Criteria | **JORC Code explanation ** | Commentary |
|---|---|---|
| techniques and sample preparation |
• If non-core, whether riffled, tube sampled, rotary split, etc and whether sampled wet or dry. • For all sample types, the nature, quality and appropriateness of the sample preparation technique. • Quality control procedures adopted for all sub-sampling stages to maximise representivity of samples. • Measures taken to ensure that the sampling is representative of the in situ material collected, including for instance results for field duplicate/second-half sampling. • Whether sample sizes are appropriate to the grain size of the material being sampled. |
the following techniques: RC drilling - 1m samples of pulverised chips, sampled by a rig mounted cone splitter, with approximately 1 to 2kg collected in individual calico bags. • Historical core was sampled at 0.3 to 1.2m intervals, cut in half using a core sore. • Based on the distribution of mineralisation the sample size is considered adequate for representative sampling. |
| 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. • 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. • Nature of quality control procedures adopted (eg standards, blanks, duplicates, external laboratory checks) and whether acceptable levels of accuracy (ie lack of bias) and precision have been established. |
• AKN samples were prepared and analysed by Jinning Testing and Inspection Laboratory, Canning Vale, Perth, WA. • RC samples are pulverised to a nominal 85% passing 75µm. • A multi-element analytical suite is assayed for using a mixed acid digest on a 0.2g charge that involves the use of nitric, perchloric and hydrofluoric acids in the attack.

• The Emull prospect is located within E80/4957. The Exploration Licence is located 44km southwest of Halls Creek, near the Great Northern Highway. • 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 after grant of the mining licences and they are not subject to the future act provisions under the NTA. |
| Exploration done by other parties |
• Acknowledgment and appraisal of exploration by other parties. |
• Several companies have explored within the Emull tenement area, primarily focusing on the potential for a significant stratabound lead-zinc system with volcanogenic affinities since the early 1970s. • The gossan outcrop capping the mineralization was discovered in the late 1960s by the local pastoralist. • From 1971 onwards a number of groups, including Pickands Mather International, North Broken Hill (NBH) were active in the area and undertook percussion and diamond drilling of the gossanous horizon at Emull. • In 1977 Shell entered into a JV with North Broken Hill to explore the nearby |

Shell withdrew from the JV in 1978 and NBH allowed the claims to lapse. • During or prior to Shell’s tenure over Emull, a resource estimate of 4.7Mt @ 4.5% Zn, 0.33% Cu, 0.2% Pb & 19g/t Ag was reported in the Independent Geologists Report by RSA Global in the Prospectus of Northern Star Resources (NST) dated 6 November 2003. • West Coast Holdings applied for 12 mineral claims in early 1981 which were later surrendered and incorporated into E80/377. West Coast referred to the prospect as the Lamboo Prospect. M80/271 was subsequently applied for and approved in March 1989. West Coast undertook shallow RAB and percussion drilling, primarily in a search for supergene enriched zones but were unsuccessful and dropped the tenement in or around 1991. • S.A. Macdonald applied for E80/1459 across the Emull prospect area in 1991. Only limited work, including hand auger drilling, general prospecting and panning and loaming were carried out. Macdonald’s tenure ceased in or around 1996. • NST commenced exploration work in the area in E80/2612 in 2003-2004 for several target styles including polymetallic mineralisation as seen at Emull, Au mineralisation as identified at nearby Nicholson’s Prospect and possible PGM mineralisation. NST undertook extensive drilling in the area, comprising 228 drill holes (RC and air core) across the tenure area and. more specifically, 88 drill holes (RC and air core) across the Emull deposit area. NST concluded exploration activities in the area in 2012. • 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 Emull base metal occurrence within the E80/4957 tenement area is hosted by altered and contact metamorphosed calc-silicate rocks, which have been intruded by and partially assimilated by the Emull gabbro. • Thin, semi-massive and disseminated mineralisation is confined to several |

|---|---|---|
| discontinuous but apparently stratabound lenses, dominated by sphalerite, with subordinate chalcopyrite and galena. The largest lens has a strike length of 500m and a maximum plan width of 50m. • The genesis of mineralisation at Emull is not certain, although models based on an origin as a volcanic hosted massive sulphide (“VHMS”) deposit partially assimilated during intrusion of gabbro, or as a skarn developed during intrusion of gabbro into carbonate units within the Koongie Park Formation, have been proposed. • Rocks of the Koongie Park property are assigned to the Lamboo Province, of Palaeoproterozoic age (1,910–1,805 Ma), which formed within the northeast trending Halls Creek Orogen. • The KPF hosts several other base metal occurrences and two significant base metal deposits, Onedin and Sandiego. • 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 is interpreted to have been the source of the metals and other constituents of the mineralisation. |

hole spacing in this portion of the deposit and classified as Inferred Mineral Resource. Extrapolation was generally half drill hole spacing between drill holes. • This is a maiden Mineral Resource estimate for the Emull deposit. • Copper, silver, lead and zinc are considered to be the economic or potentially economic metals. Additional studies are required to confirm this. Further metallurgical test work is required to assess potential deleterious elements. • The parent block dimensions used were 10m EW by 5m NS by 5m vertical with sub-cells of 2.5m by 1.25m by 1.25m. The parent block size dimension was selected on the results obtained from Kriging Neighbourhood Analysis that suggested this was the optimal block size for the Emull dataset. • An orientated ‘ellipsoid’ search was used to select data and adjusted to account for the variations in lode orientations, however all other parameters were taken from the variography. Three passes were used. The first pass had a range of 50m, with a minimum of 8 samples. For the second pass, the range was 100m, with a minimum of 6 samples. For the third pass, the range was extended to 200m, with a minimum of 2 samples. A maximum of 20 samples was used for all three passes. • No assumptions were made on selective mining units. • Correlations exist between copper and the the remaining elements. Silver and lead had a strong positive correlation. • The deposit mineralisation was constrained by a cut-off grade of 0.1% copper for mineralisation.

It is always necessary as part of the process of determining reasonable prospects for eventual economic extraction to consider the potential environmental impacts of the mining and processing operation. While at this stage the determination of potential environmental impacts, particularly for a greenfields project, may not always be well advanced, the status of early consideration of these potential environmental impacts should be reported.

| Classification | • The basis for the classification of the Mineral Resources into varying confidence categories. • Whether appropriate account has been taken of all relevant factors (ie relative confidence in tonnage/grade estimations, reliability of input data, confidence in continuity of geology and metal values, quality, quantity and distribution of the data). • Whether the result appropriately reflects the Competent Person’s view of the deposit. |
• The Mineral Resource estimate is reported here in compliance with the 2012 Edition of the ‘Australasian Code for Reporting of Exploration Results, Mineral Resources and Ore Reserves’ by the Joint Ore Reserves Committee (JORC). The Mineral Resource was classified as Indicated and Inferred Mineral Resource based on data quality, sample spacing, and lode continuity. The Indicated Mineral Resource was defined within areas of close spaced drilling of less than 25m by 20m, and where the continuity and predictability of the mineralised units was reasonable. The Inferred Mineral Resource was assigned to areas where drill hole spacing was greater than 25m by 20m and less than 80m by 80m; where small, isolated pods of mineralisation occur outside the main mineralised zones, and to geologically complex zones. • The input data is comprehensive in its coverage of the mineralisation and does not favour or misrepresent in-situ mineralisation. The definition of mineralised zones is based on high level geological understanding producing a robust model of mineralised domains. This model has been confirmed by recent infill drilling conducted by AKN, which supported the interpretation. Validation of the block model shows good correlation of the input data to the estimated grades. • The Mineral Resource estimate appropriately reflects the view of the Competent Person. |
