- Visible gold observed in holes VDD009 & VDD014
Viking Mines Limited (ASX: VKA) (“ Viking ” or “ the Company ”) is pleased to announce high-grade results from the 18 hole 3,924m diamond drilling programme on the Company’s flagship First Hit Project ( “First Hit“ or “ the Project ”), 50km west of Menzies in the WA Goldfields.
Holes VDD013 and VDD015 (Figure 1) of the maiden diamond programme were designed to achieve two objectives – firstly to test continuity and style of mineralisation of the Evans lode occurring at depth below the deepest limits of the historic mine workings and secondly, to obtain key geological information to be used for further targeting of extensions.
Importantly, both objectives were achieved, with drilling successfully intersecting significant, high-grade mineralisation at depth, with VDD015 delivering 7.06m at 5.93g/t Au , (including 0.5m at 71.64 g/t Au - Figure 2) and VDD013 delivering 5.0m at 3.67g/t Au (including 1.0m at 11.16g/t Au - Figure 3). Key geological information obtained includes structural data (providing information on the orientation of shearing, veining, mineralisation and lithological contacts) and alteration data to characterise the mineralogy associated with the gold bearing mineralisation. Notably mineralisation is open down plunge from hole VDD013 with no drilling to the south.
Holes VDD009 and VDD014 (Figure 1) were drilled to test continuity and style of mineralisation occurring at depth below the limits of mining to the 300m RL on the northern stopes mined from the Kylie lode. Both holes were successful in identifying continuation of both grade and structure and with visible gold observed after the receipt of assay results (Figure 4 & Figure 5). The Company also obtained the same key geological information on structural data and alteration associated with gold bearing mineralisation, all of which will be used for further targeting of extensions.
The Company is buoyed by the result of step-out hole VDD016, where the core showed multiple pieces of visible gold and assaying returned a high-grade intersection of 1.0m at 13.52 g/t Au from 57.0m (Figure 6). This close-to-surface intersection is located 165m

north of the current high-grade shoot at First Hit and provides Viking with an exciting target, which has the potential to represent and form a second high-grade shoot (Figure 1).
The results of the diamond drill programme have provided the Company with a stronger understanding of the mineralisation and geology at First Hit. Planning for the next major drill programme has commenced and Viking will utilise key data from the recent drill campaign to establish a detailed programme which will focus on targeting extensions below the Kylie and Owens lodes and follow-up drilling at hole VDD016.
All gold and multielement analysis results have been received for the samples submitted to the laboratory and only the pXRF data remains outstanding.
Commenting on the high-grade intersections at depth and excellent step out result Viking Mines Managing Director & CEO Julian Woodcock said “The latest set of highgrade results are highly encouraging and provide the Company with critical information on the mineralisation and geology of First Hit. Importantly, we are hitting high-grade gold at depth, observing visible gold in numerous holes and what really excites us is the high-grade, near-surface intersection from our step-out hole, 165m away from the First Hit shoot. This is now a completely new target and we are very eager to further explore and see if there is any replication of the historically-mined gold shoots.
“The Company is well-funded to continue aggressively drilling at First Hit and have already commenced planning for our next major drill programme, which will focus on testing both the known extensions to the mine below the Kylie and Owens lodes as well as the new potential shoot to the North.”
DIAMOND DRILLING RESULTS – EXTENDING FIRST HIT
Drillholes VDD015, VDD013, VDD014 & VDD009 have all demonstrated the potential for mineralisation to extend beyond the current defined limits (Figure 1) with the presence of gold bearing quartz veins encountered in all 4 holes.
VDD015
Very high-grade assay results exceeding 40 gram-metres have been returned associated with 3 narrow quartz veins and visible gold. Key features are summarised below:
-
3 distinct mineralised intervals (Figure 2) related to narrow quartz veins occurring in a broader mineralised zone:
-
7.06m at 5.93g/t Au from 296.94m including:

STEP OUT DRILLING IDENTIFIES NEW TARGET
Four step out holes were drilled as part of the drilling programme (VDD016 to VDD019 - Figure 1) with a gold bearing quartz vein intercepted in hole VDD016[1] .
No significant assays were received in holes VDD017 to VDD019, however low-grade gold halo values have been observed in all 3 drillholes indicating potential continuation of the gold bearing structure.
VDD016
A high-grade assay results is associated with a 1m sample containing a 20cm quartz vein with visible gold. Key features are summarised below.
-
1.0m at 13.52g/t Au from 57m downhole
-
Located 165m north of existing workings (Figure 7)
-
Vein intercepted ~50m below surface and ~60m east of the First Hit boxcut
-
Historical drillhole BFHN010 drilled 45m north intercepted 2.09g/t from 76m downhole from a re-split 4m composite sample
-
This is an important observation as the sampling method is not optimal for narrow vein high grade gold deposits and has the potential to ineffectively sample the rock for gold

ABOUT VIKING MINES
Viking Mines is a gold focussed company with the First Hit Project located 150km NW of Kalgoorlie in Western Australia being the primary asset under exploration.
Viking have an aggressive exploration strategy to explore for high grade gold occurrences and discover ounces along fertile gold structures. The historically mined, First Hit gold mine is the focus of Vikings activity to deliver on this strategy. Rapid advancement and exploration are occurring to explore, discover and develop gold ounces at the Project. The strategy will generate shareholder value through the discovery of new gold resources.
First Hit Project, Western Australia
The First Hit Project is centred around the historic high-grade First Hit gold mine situated along the prospective Ida and Zuleika
==> picture [302 x 305] intentionally omitted <==
Shear zones in the Eastern Goldfields of Western Australia. The Project incorporates ~28km[2] of tenements with 6 active Mining and Prospecting licences and 1 Exploration licence under application. At the core of this landholding is a 6.4km[2] group of contiguous tenements which host the historic First Hit gold mine.
Prior to closure of the First Hit gold mine by Barra Resources in 2002 and at a time of depressed gold prices of US$ 320/oz, the First Hit mine produced ~30koz ounces of gold at an average grade of ~7.7g/t Au. No modern exploration activity has been conducted in the past 18 years and creates a significant opportunity for Viking. The Company is focused on delivering exploration programmes to test near mine extensions and regional targets around the First Hit Project with the objective of defining fertile structures and discovering gold ounces.
Examples of the high-grade nature of the mineralisation previously drilled at First Hit include:
-
4.9m at 64.8g/t Au from 62.1m (FHU045)[1]
-
3m at 77.6g/t Au from 224.0m (BFH030)[ 1]
-
4m at 26.1g/t Au from 58.0m (BFH005)[ 1]
The Project area is well serviced by infrastructure and is located 50km west of the sealed Goldfields highway and the township of Menzies. The nearest operating Gold Processing Plant is the Davyhurst Mill 50km to the south, owned and operated by Ora Banda Mining (ASX:OBM). The nearest operating gold mine is the Riverina open pit, located 8km south of the First Hit gold mine, owned by OBM.
The Company also has projects located in Ghana. Viking is currently undergoing legal proceedings to secure costs and interest associated with the sale of the Akoase project in Ghana.

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 downhole gamma sondes, or handheld XRF instruments, etc.). These examples should not be taken as limiting the broad meaning of sampling. |
Historical Surface Geochemistry Several companies have undertaken surface exploration through the history of the tenement including Riverina Gold, Croesus Gold, WMC, Barminco and Barra Gold. A total of 24,289 samples have been collected, however CSA Global has limited information on these surveys apart from WMC and Barminco, as described below. WMC mining completed several phases of soil geochemistry between 1990 and 1992 with 2,836 samples collected. This included: • Stream sediment geochemistry from active streams from contemporary lags within stream beds. • 2 kg pan concentrate samples collected from trap sites in active drainage channels. • Soil samples collected from 5-15 cm depth or 15-30 cm depth depending on soil thickness and passed through -10#, +36#, - 80# or 120# meshes. • Surface soil sampling was sieved through a 6 mm mesh. Barminco Pty Ltd undertook 2 geochemical soil geochemistry programs on the northern part of M30/99 between 1995 and 2000. The first soil survey completed was designed to test areas of residual soil and outcrop, whereas the second soil survey tested areas covered by shallow transported cover. In areas of residual soil and outcrop –80 mesh soil samples were collected on a 50 m x 50 m spaced grid and analysed for gold and arsenic. In areas of transported cover, a preliminary 100 m x 400 m spaced auger soil sampling program was undertaken. The details of the sampling methods and horizons tested for the -80# mesh soil sampling and auger sampling are not described. WMC collected ironstone float rock chip samples (number unknown) across the tenements. Barminco completed undertook rock chip sampling between 1996 and 2002, though the number of samples collected is unknown. Rock chips are described as being collected also taken in areas with cover, laterite development and recent drainage areas for pathfinder and mapping purposes. Historical Surface Drilling WMC completed 13 RC drill holes and one diamond drill hole during their tenure between 1990 and 1992. No descriptions of the nature of the sampling are available. Barminco completed core and diamond drilling of holes up to 346 metres below surface over the First Hit Project area mineralisation. 21 RC holes were completed north and south along strike from the deposit testing for repeats of the First Hit mineralisation. Percussion samples were split at the drill sites and a 2-5 kg sample was taken for processing and analysis. Probable waste zones were sampled by compositing over 2-4 metres and individual samples were retested if the composites were anomalous. Diamond drill core from was split length ways and half was used for initial analysis whilst the remaining half was used for reference material (kept used for metallurgical testing as required). Historical Underground Ore Control and Definition: Underground resource definition drilling using drill core provided solid core samples for analysis. During mining operations face channels and production drill holes were used to assist with ore definition and control. Whole core was sampled from UG drill core. Historical Underground Face Sampling As drives advanced Barminco geologists/technicians carried out rock chip sampling across the exposed drive face. Not all drive advance faces were mapped or sampled. The samplingwas treated similarlyto a drill hole although typicallyundertaken as a |

| ‘channel’ rock chip sample along a pre-determined line at right angles to the dip of the vein structures/mineralisation. The face was mapped and significant geological features recorded. The sample line attitude (dip), sample number, sample length, and sample lithology recorded. In addition, the assay result for gold (Au) were recorded following receipt. Summary of VKA 2021 Exploration Drilling and Sampling Diamond drill core sampling was undertaken utilising half core designated by CSA Global personnel which was marked up with a cutting line and sent to Dynamics G-Ex contractor in Kalgoorlie, where half core was sampled. Core that was not sampled was sent to the VKA facility in Perth for storage and subsequently all cut core is stored in Perth at a VKA facility Aircore samples were collected at the drill rig during the drilling process. Samples were collected from drill spoils by a scoop over 2m composites with a 1m end of hole bedrock sample taken for each hole. The samples collected were between ~0.5 and ~3kg and submitted to MinAnalytical laboratories for analytical work. Additionally, handheld XRF analysis was undertaken on some but not all aircore samples (described below) The Competent Person considers these samplingmethods appropriate for this style of mineralisation. |
||
| Include reference to measures taken to ensure sample representivity and the appropriate calibration of any measurement tools or systems used. |
Historical Information The entire RC sample was collected and sampled at the drill rig; samples from diamond drilling were subsampled in a core handling facility. Diamond and RC field duplicates were taken on selected intervals within the interpreted mineralised horizons to measure representativity of sample splits. Historical Underground Face Sampling No information is provided in available reports to ascertain the representivity of the face sampling, though some face maps show both selective and mark ups for sampling lines across the lode. No information has been located relating to QAQC procedures such as duplicate sampling, certified standards or laboratory repeats or standards. Summary of VKA2021 Exploration Drill Sampling Diamond drill core is cut and sampled along designated cut lines in areas of geological and interpreted mineralisation to provide representative sampling. The position of the cut line on the diamond core is chosen to ensure that the selected sample is representative. Aircore sample recovery was monitored for excessive sample loss and recorded to ensure sample representivity. The Competent Person considers these samplingmethods appropriate for this style of mineralisation. |
|
| 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 |
Historical Sample Preparation Sample preparation for RC and diamond drilling consisted of coarse crushing a maximum of 3 kg of the submitted sample, pulverising to >85% passing 75 microns and homogenising the pulp for all sample types. 50 g sample sizes were chosen for analysis of gold, with fire assay fusion and detection by atomic absorption spectrometry (AAS). Historical Underground Face Sampling Available reports indicate gold distribution is often erratic and visible Au noted in many face samples. It is not known what steps were taken to address the issue of ‘nuggety’ Au and sample bias. Face sampling appears to have been both selective and along sampling lines on face maps. Summary of VKA 2021 Exploration Drill Sampling Diamond drilling was drilling HQ core (63.5mm) to provide a larger core diameter for better representivity of sampling given the potential for coarse gold. Between 20cm and 1m (generally 1m) of half core is being sampled by Dynamics G-Ex contractor in Kalgoorlie. The assay methodology is described below. Diamond core analysis: Fie assay analysis was employed where intervals of interest were interpreted to be lower grade and/or away from the historical workings. For fire assay between 0.5kg and 6kg of half core sample is pulverised to produce a 50g charge for fire assay. All pulp samples are analysed by Laboratory portable XRF. Selected samples to characterise host rocks and alteration are digested bya 4-Acid digest and analysed for 60 elements usinga ICP-OES/MS finish. |

| Photon Assay: Samples were analysed at MinAnalytical in Perth where samples were interpreted to be possibly high grade such as core near zones of historical mineralisation. The analytical method used was a 500 g Photon Assay, a non-destructive method for gold only. Aircore sample analysis: Aircore drilling was used to obtain 2m composite and individual 1m end of hole samples from which 3 kg was pulverised to produce a 50 g charge for fire assay. Selected drill samples were analysed pXRF in the field and in Minanalytical Laboratory. Selected samples to characterise host rocks and alteration are digested by a 4-Acid digest and analysed for 60 elements using a ICP-OES/MS finish.

Historical Drilling Drillhole data over the First Hit Project area comprised 295 holes, consisting of 187 RC, 3 surface diamond holes, 55 RAB holes, and 50 UG DDH holes, with an additional 504 UG face channel samples (collected as horizontal channels across the ore drive headings). RC samples were collected using a face-sampling, 4.5-inch diameter bit via the inner return tube to a sample splitter. Surface diamond core drilling utilised an NQ2 size (50.6 mm) drill bit. The core diameter for underground drilling could not be obtained from available reports however from the corephotos the core size appears to be NQ.

Historical Information No documentation regarding the measurement of drill core or RC recoveries could be found in the various reports and tables in the available data. The following comment is extracted from the 2001 First Hit Mine Ore Resource and Mining Report: “Sample recoveries throughout the drilling programs has been excellent (majority greater than 80%) with no major problems encountered” CSA Global briefly reviewed historical drill core stored on site (holes un-labelled) and core photographs of underground drill holes (FHU001, FHU019, FHU041, FHU044, FHU045, FHU046, FHU052, FHU055) and noted that core was in good condition with long intervals of unbroken core and no evidence of poor recoveries. CSA Global through examining core photos is satisfied that core recoveries were adequate though better documentation by the original project owners in this regard would have been more conclusive. |

| Summary of VKA 2021 Exploration Drilling Recoveries of diamond drill core were measured by using the drillers blocks as a guide and determining the actual length of core vs the measurement between drillers blocks. Within the fresh zone drill recoveries were greater than 90%. In the oxide zone core was only retrieved in competent rock which typically coincided with the fresh rock interface. Aircore drilling recoveries were visually estimated and recorded as part of geological logging process. The Competent Person considers the recovery measurement methods appropriate for this style of mineralisation. |
||
| Measures taken to maximise sample recovery and ensure representative nature of the samples. |
Historical Information Sampling techniques were chosen as appropriate for ground conditions to maximise sample recovery. There is no additional record of measures in place to maximise recovery. Summary of VKA 2021 Exploration Drilling Drilling was undertaken with a HQ assembly to maximise core size and therefore recovery and triple tube was utilised to ensure core could be recovered, near surface, notwithstanding that the targets were wholly within fresh rock where recovery was greater than 90%. Aircore drilling sample recovery was monitored to ensure representivity of the samples. Drilling used standard drilling equipment and procedures that are suitable to maximise sample recovery and the representative nature of the samples. The Competent Person considers these sampling techniques and measures to ensure representivity appropriate for this style of mineralisation. |
|
| 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. |
Historical Information Insufficient information on sample recovery is available to establish whether a relationship between sample recovery and grade exists. Summary of VKA 2021 Exploration Drilling The high recovery achieved from current diamond drilling indicates there is unlikely to be bias in recovery/ analytical results. Aircore drilling used standard drilling equipment and procedures that are suitable to maximise sample recovery and the representative nature of the samples. The relationship between sample recovery and grade is not a significant factor in determining anomalism in aircore drilling. The Competent Person considers there to be limited bias related to the recovery/samplingat the First Hit mineralisation. |
|
| 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. |
Historical Information All RC and diamond drillholes were geologically logged to an industry standard appropriate for the mineralisation present at the project. All RC drill chip samples were geologically logged at 1 m intervals from surface to the end of each drillhole. Diamond core was photographed, and RC chips were retained in chip trays for future reference. Ausdrill completed three, NQ2 diamond drill holes at the First Hit deposit for geotechnical assessment prior to mining. The holes were designed in consultation with Golder Associates Pty Ltd and were targeted into the mineralised zones and continued on average 30 m into the footwall to assess the likely ground conditions for the decline and ore accesses. Approximately 70 metres of core was drilled for each hole allowing the hanging wall, the ore zone and the footwall zone to be assessed. Golders Associates Pty Ltd were commissioned to undertake the geotechnical assessment. The Competent Person considers that the level of detail is sufficient for geotechnical studies. Historical Underground Face Sampling The underground face samples were used to guide mine development. Due to the lack of information regarding the quality of the face samples these should be regarded as qualitative only and can only be used to provide an indicative guide as the presence or otherwise of mineralisation. Summary of VKA 2021 Exploration Drilling Diamond drill core is logged to a geological detail suitable for a mineral resource estimate ensuring all lithology, alteration and interpreted mineralisation is recorded and drillingcontinues through the footwall wherepossible. Geotechnical loggingis recorded in |

Aircore sample logging of rock chips samples from drill cuttings are undertaken as a first pass indication of potential gold and multi- element anomalism. Samples of rock chips from drill cuttings were logged by the geologist in the field, for parameters including, depth, colour, grain size, weathering, lithology, alteration, and the presence of minerals potentially related to mineralisation including quartz and pyrite. The Competent Person considers the loggingmethods appropriate for this style of mineralisation. |

| Whether logging is qualitative or quantitative in nature. Core (or costean, channel, etc.) photography. |
Historical Information Lithological logging is qualitative in nature. Logged intervals were compared to the quantitative geochemical analyses to validate the logging. The Competent Person considers that the availability of qualitative and quantitative logging has appropriately informed the geological modelling, including weathering and oxidation, water table level and rock type. Historical Underground Face Sampling The logging of the underground face samples is qualitative only. Summary of VKA 2021 Exploration Drilling Logging of aircore and diamond drilling is qualitative in nature. All drill core and aircore samples are photographed. Aircore samples were photographed on the ground and rock chips in chip trays. The Competent Person considers the loggingmethods appropriate for this style of mineralisation. |

Historical Underground Face Sampling The underground face sampling hardcopy plans indicate in the majority of cases the face was sketch mapped and the ‘channel’ geologically logged with the sample length or interval recorded. Summary of VKA Exploration Drilling All diamond and aircore drilling were geologically logged with detailed logging in areas of interest. The Competent Person considers the loggingmethods appropriate for this style of mineralisation. |

Historical Information Diamond core was cut into two halves using a diamond core saw for surface drilling. One of the halves was placed into a numbered calico bag, which was tied and placed in a plastic/poly-weave bags for assaying. Underground DDH samples were whole core sampled. Summary of VKA 2021 Exploration Drilling Diamond core was cut into two halves using a diamond core saw for surface drilling. One half of the core is used in the assay process. This work was undertaken by a trained contractor group (Dynamics G-Ex) The Competent Person considers the samplingmethods appropriate for this style of mineralisation. |

Historical Information RC samples were collected via a splitter to yield sub samples of approximately 3 kg from a 1 m downhole sample length. Expected waste zones were initially sampled as 2 m or 4 m composites and later resampled at 1 m intervals if anomalous assay results were returned. Re-sampling was undertaken using the spear sampling method Summary of VKA 2021 Exploration Drilling AC samples were collected from drill spoils by a scoop over 2m composites with a 1m end of hole sample taken for each hole. The samples collected at a weight of between ~0.5 and ~3kg No sub-sampling or further sample preparation for samples derived from AC drillingis beingreported. Most of the samples were dry. |

| Quality control procedures adopted for all subsampling stages to maximise representivity of samples. |
Historical Information CSA Global were unable to establish QAQC processes involving the use of CRM, including blanks and standards. The following is described from the First Hit Mine Ore Resources and Mining Report, 2001 and indicates duplicates were used to inform the resource model. “Several samples were often submitted for each positive assay. These were taken on site and submitted to the same laboratory under a different sample number and then assayed using the same technique. An average of these results for each interval has been used within the ore resource calculations”. CSA Global does not consider the above process to be suitable as a form of QAQC. The lack of CRMs is not industry practice. CSA Global recommends the application of industry standard QAQC to all future drilling programs. Historical Underground Face Sampling CSA Global were unable to establish QAQC processes involving the use of CRM, including blanks and standards. Summary of VKA 2021 Exploration Drilling No sub sampling has been applied to the current drill programmes for either the diamond drilling or Aircore drilling. The Competent Person considers the current methods of samplingas described as appropriate for this style of mineralisation. |
|
| 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. |
Historical Information See comments above regarding the use of duplicates by Barminco. Several samples were often submitted for each positive assay. These were taken on site and submitted to the same laboratory under a different sample number and then assayed using the same technique. An average of these results for each interval has been used within the ore resource calculations. Historical Underground Face Sampling CSA Global were unable to establish representivity of the face samples or the use of field duplicates or assaying of sample splits. Summary of VKA 2021 Exploration Drilling CSA Global have applied industry standard QAQC procedures for sampling processes to diamond drilling and aircore drilling programs. Diamond drilling At this stage no further sub-sampling methods have been applied. No duplicate/second half sampling was undertaken which may also be revised depending on all assay results received. Aircore drilling No field duplicates were collected as the current sampling is considered appropriate for determining anomalism rather than exact results. The Competent Person considers the current methods andprocesses described as appropriate for this style of mineralisation. |
|
| Whether sample sizes are appropriate to the grain size of the material being sampled. |
Historical Information The First Hit Project mineralisation and targets within the associated tenements are expected to be coarse grained and nuggety gold. Further exploration will need to consider the grain size of gold and distribution of particles. No previous petrology reports were found, and future work will include petrological studies in the early stage of exploration. Historical Underground Face Sampling No information is available re sample size. The mineralisation is known to include nuggety visible Au. Summary of VKA 2021 Exploration Drilling The mineralisation at the First Hit project is historically recorded as containing coarse gold. As such the diamond drilling program is utilising HQ core as the appropriate core size to maximise the potential to intersect any course gold if present. All host rocks are fine grained and HQ core size is appropriate for the grain size. The Aircore drilling is aiming to detect gold anomalism and the sample sizes are considered appropriate to the grain size of the material being sampled given the style of mineralisation being targeted. The Competent Person considers the current methods andprocesses described as appropriate for this style of mineralisation. |

| 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. |
Historical Information 7,865 samples were prepared for Fire Assay and tested by Kalgoorlie Assay Laboratory. There are incomplete records for the remaining 2,150 samples. Fire Assay is considered a total digest and whilst generally appropriate for the type of mineralisation, cyanide bottle roll leach test work may be recommended for exploration should coarse gold be encountered in future exploration. Historical Underground Face Sampling No information is available with respect to the quality of the face samples. Summary of VKA 2021 Exploration Drilling All samples were analysed by MinAnalytical laboratory in Perth. The analytical technique for the diamond drill core samples for Au concentrations consists of the Fire Assay method (50g charge) for lower gold grade samples and 500g Photon assay for high grade gold samples. The 500g Photon assay technique is more appropriate for higher grade nuggety samples due to the higher sample charge compared to the fire assay method. All core samples are analysed by a Laboratory portable XRF and selected samples by 4 acid digest with a ICP-OES/MS finish to characterise host lithologies and alteration. Fire assay technique is considered a total technique. The four-acid digest ICP-OES/MS technique is considered total for most rock types except for rocks containing very resistant minerals such as spinel. The Photon assay technique is considered a total technique. The analytical techniques for the aircore samples include: Fire Assay method (50g charge) for gold, four acid digest with ICP-MS/OES finish for 60 elements, and pXRF method for 34 elements. The analytical technique for Au is considered total with the rest being mostly partial. The Competent Person considers the current methods andprocesses described as appropriate for this style of mineralisation. |
| 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. |
Historical Information No non-destructive tools or devices are recorded as being used. Summary of VKA 2021 Exploration Drilling A pXRF survey has been completed in the field using a handheld instrument by Bruker, the S1 Titan 800 model. The measurements were completed in three ranges (Exploration Mode) with 20 counts per range. Autocalibration measurements were used for reading checks and adjustments. A Olympus Vanta portable XRF is used for diamond core and aircore sample pulps on hand pressed cups. Autocalibration measurements are used for reading checks and adjustment. The Competent Person considers the current methods andprocesses described as appropriate for this style of mineralisation. |
|
| Nature of quality control procedures adopted (e.g. standards, blanks, duplicates, external laboratory checks) and whether acceptable levels of accuracy (i.e. lack of bias) and precision have been established. |
Historical Information CSA Global has not been able to obtain the original assay certificates for exploration and resource drilling on the First Hit Project tenements. As recorded in the QC procedure section duplicates were used as a way of informing the resource model. For future exploration it is recommended that standard CRMS, blanks and duplicates be used for QAQC. Underground Face Sampling No information is available with respect to QAQC procedures. Summary of VKA 2021 Exploration Drilling The QAQC procedures for the diamond drill core samples for fire assay consists of the analyses of a certified standard and blank for every 20 samples. One QAQC fire assay standard failed and the 8 samples either side of failed std have been reanalysed, including a new standard. The QAQC procedures for the aircore drilling program consists of the analyses of a certified standards (every 20 samples) and blanks (every 40 samples). The QAQC for Photon analysis averaged approximately 1 every 5 samples. There was one failure, however the failed Std repeated, indicatingthere was apotential mixed standard. |

| All Viking QAQC protocols were met, and analysis results passed required hurdles to ensure acceptable levels of accuracy and precision attained for exploration purposes. One high grade Photon STD failed, however on the balance of the program the QAQC was of a satisfactory quality. The Competent Person considers the QAQC described as appropriate for this style of mineralisation. |
||
| Verification of sampling and assaying |
The verification of significant intersections by either independent or alternative company personnel. |
Historical Information Due to the samples being sampled and collected 20 years ago, independent verification is difficult and has not been undertaken. CSA Global recommend unpacking the remaining drill core on site and reviewing the geology, alteration, structure and mineralisation. Underground Face Sampling No independent verification has been undertaken so far, however the hardcopy plan data is being entered into a database, which will facilitate checking of assay data presented on the face sampling plans against that recorded in Barminco and Barra Resources reports. Summary of VKA 2021 Exploration Drilling CSA Global are contracted to Viking Mines Limited and internal checking processes including regular checks of structure and veins by alternative personnel for relevance to historical mineralised mined areas and historical drill intersections. The returned laboratory assay results have been reviewed and where returned standards are outside two standard deviations from the expected value the batch of samples have been re-analysed. The Competent Person considers theprocess described as appropriate. |
| The use of twinned holes. | Historical Information No twin drilling has been undertaken; however, significant reported underground development and sampling has verified the information provided by the surface drilling. Some twinning of drill holes for exploration purposes is recommended by CSA Global. Summary of VKA 2021 Exploration Drilling There were no twinned holes drilled in the current diamond drill program, however the drill holes completed for the diamond drilling program are located within areas proximal to the drilling completed as part of the previous operator's resource drilling. There are no twin holes for the aircore program. The Competent Person considers theprocess described as appropriate. |
|
| Documentation of primary data, data entry procedures, data verification, data storage (physical and electronic) protocols. |
Historical Information The data entry, storage and documentation of primary data was completed in Microsoft Access databases and assembled by CSA Global into a central database for future purposes. The majority of the data reviewed by CSA Global has been summarised from primary sources. Underground Face Sampling No independent verification has been undertaken so far, however the hardcopy plan data is being entered into a database, which will facilitate checking of assay data presented on the face sampling plans against that recorded in Barminco and Barra Resources reports. The face sampling data is presented as a series of Tables in Barra Resources report –‘Final Mine Report, 2002’ and submitted to DMIRS. Summary of VKA 2021 Exploration Drilling Diamond Drilling: Primary logging data were entered into a protected spreadsheet which was then uploaded into relational data base. Aircore Drilling: Primary data for drill cuttings, including sample number, depth, colour, grain size, weathering, lithology, alteration, and the presence of minerals potentially related to mineralisation including quartz and pyrite, were collected in the field and entered into a protected spreadsheet which was then uploaded into relational database. The Competent Person considers theprocess described as appropriate. |

| Down hole surveying of drill holes were undertaken on the majority of holes whilst being drilled. This has enabled only dip readings to be collected as the instrument was used within the drill string. Several programs of downhole surveying using a single shot Eastman camera have been completed for all available holes in the First Hit area and have been incorporated into the database. Where downhole surveys were unavailable due to the collapse of the hole, survey estimates at regular intervals have been applied. These are based on the deviation of the surrounding drill holes. Drill holes greater than 100 m in depth deviated consistently in the azimuth to the southwest (against rotation). The dip angle in most cases steepened and in some of the deeper holes this was quite dramatic. Drill string stabilizers were tried at various times in an attempt to help alleviate this problem, but no consistent results were achieved. Historical Underground Face Sampling The location of face sampled was recorded by mine surveyors. The face samples were used to guide mine development. It is unknown the extent the face sample data was used in Mineral Resource estimates. Summary of VKA 2021Exploration Drilling–Surveys Diamond drilling. The collar positions were surveyed using a differential GPS with an accuracy of +/-0.5m. The downhole azimuth and dip were surveyed using a Reflex Easy Gyro tool with an accuracy of +/- 1 degree for the azimuth and +/-0.1 degrees for the dip. Aircore drill hole collar positions were located by hand-held GPS during drilling. Expected accuracy is +/- 5m for northing and easting. There are no down hole surveys and drill holes are vertical. These are not part of a resource estimate. Additionally, Specialist remote sensing operators Sensorem (sensorem.com.au) were engaged to undertake a high-resolution survey using the Wingtra Hovermap® drone systems. The purpose of these surveys is to provide a Digital Terrain Model (DTM) across the contiguous tenure, high resolution images and 3D LiDAR scans of the underground workings. These surveys will provide datasets to support the regional AC programme with geological interpretation The Competent Person considers theprocesses for diamond collar,underground and aircore collar locations as appropriate. |
||
| Specification of the grid system used. | Historical Information Topographic data for the mine drilling were captured in MGA Zone 51 grid. A local grid has been established at First Hit, which is orthogonal to the known mineralised trend of the area (020 degrees). The grid orientation is at 290 degrees magnetic which is optimal for this deposit. The conversion from local to AMG 84 grid is presented in the table below. Summary of VKA 2021 Exploration Drilling The GDA94 Zone 51 datum is used as the coordinate system. |
|
| Quality and adequacy of topographic control. | Historical topographic Information Historical survey work for the First Hit Mine was conducted via differential global positioning system (DGPS) and is appropriate as an industry standard method. A topographic surface used for coding the block model was built from a system using a detailed drone survey. The Competent Person considers that the surface is suitable for future exploration activities. Summary of VKA 2021 Exploration Drilling The DTM and collar locations for the diamond drilling were located by differential GPS. Topographic control on Aircore drill holes is from DTM and hand-held GPS. Accuracy +/- 5m. The Competent Person considers theprocesses for diamond collar and aircore collar locations as appropriate. |

| Diamond drilling is completed on an irregular pattern targeting specific targets in and around the existing mine workings. Aircore drilling was conducted on fence lines 200-400m apart with 50 m hole spacing. The Competent Person considers the data spacingfor diamond drillingand aircore drillingappropriate for reportingexploration 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. |
Historical Information Existing drilling on the periphery of historically mined areas is suitable for defining additional drill targets laterally, down dip and in the near surface environment. Summary of VKA 2021 Exploration Drilling The diamond drilling is considered appropriate for exploration drilling for this type of deposit and no resources are currently being estimated. The AC sample spacing is considered suitable for first pass testing of exploration targets for gold mineralisation in the Yilgarn Craton of WA. |
|
| Whether sample compositing has been applied. | Historical Information Sample composting was applied in initial exploration drilling at the First Hit Project and always followed up by detailed sampling at 1 m interval, or less for core drilling. Summary of VKA 2021 Exploration Drilling No sample compositing has been applied for diamond drill core samples. Two-metre sample compositing has been applied for all but the end of hole Aircore drill samples. The Competent Person considers the sampling for the diamond drill core appropriate and the compositing of the aircore samples to be appropriate for This stage of exploration. |
|
| 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. |
Historical Information The regular spaced drilling on consistent sections, and the orientations orthogonal to the strike of the lodes, has provided consistent support to intersections of mineralisation to eliminate any bias or influence of hole angles on grades. Summary of VKA 2021 Exploration Drilling Diamond drilling is predominately orthogonal to the strike of the deposit, with one hole drilled oblique to the mineralisation to intersect several additional lithological units. The variable dip of the veins means the drill hole will intersect the veins at different core angles. understanding the geometry of the vein system is managed through incorporating as much of the underground mapping and historical drilling as possible. Additionally, all diamond holes are oriented to understand and measure the variability of structures and mineralisation. Aircore drill fences were oriented across the known geological structures in the area. No drill hole orientation has been applied. The drill hole spacing, and orientation is considered appropriate for first pass testing of exploration targets for gold mineralisation in the Yilgarn Craton of WA. The Competent Person considers theprocesses for diamond collar and aircore collar orientations as appropriate. |
| If the relationship between the drilling orientation and the orientation of key mineralised structures is considered to have introduced a sampling bias, this should be assessed and reported if material. |
Historical Information No relationship has been noted between drillhole orientation and mineralisation. Summary of the VKA 2021 Exploration Drilling At this stage in the exploration process, neither the diamond drilling nor aircore drilling is considered by the Competent Person to have introduced a samplingbias. |
|
| Sample security | The measures taken to ensure sample security. | Historical Information The competent person is unaware of measures taken to ensure sample security during past exploration. Chain of custody procedures are recommended for future exploration. Summary of VKA 2021 Exploration Drilling Diamond core and AC Samples were collected and stored byCSA Globalpersonnel near the campfacilities in theproject area. |

| Exploration done by other parties |
Acknowledgment and appraisal of exploration by other parties. | The Red Dirt tenements have been actively explored and mined since 1886 with the arrival of prospecting parties during the initial Western Australia gold rush. Arthur and Tom Evans founded the First Hit gold mine in 1938. Tom and Arthur worked the mine until Tom sold his share to Riverina station owner Bill Skathorpe in late 1953. Arthur and Bill worked the mine until Bill's death in 1954. George Vujcich Senior bought the mine from Arthur and Bill's estate in late 1955. George and then his son George operated the mine intermittently over a 40-year period. Barminco purchased the First Hit tenement from George's daughter in late 1996. Regional exploration activities were undertaken by Western Mining Corporation (WMC) and Consolidated Gold Operations prior to 1996 including geochemical sampling, lag sampling and auger programs. The programs covered the various regolith features with a purpose of defining broad geochemical anomalies. From 1996 to 2002 exploration and development was undertaken by Barra Resource or Barminco. Barminco Pty Ltd undertook geochemical soil geochemistry on the northern part of M30/99 between 1995 and 2000. Various combinations of multielement geochemistry were completed historically, ranging from gold-only assays to 42 element geochemistry. The following extract from the Barra Resources mine closure and production report provides an insight to the exploration and discovery of the First Hit deposit: “Barminco Pty Ltd acquired the First Hit tenement in August 1996, with the objective of exploring for and developing moderate sized high grade gold deposits. Because of Barminco’s mining and exploration activities at Two Boys, Karonie, Jenny Wren, Gordon Sirdar and Bacchus Gift mines the period between August 1996 and June 2000 saw only intermittent work at First Hit. Twenty RC drill holes were completed demonstrating the potential for high-grade underground resources. The First Hit deposit was effectively discovered in June 2000 with drill hole BFH 025 which returned 3 zones of mineralisation including 5m @ 60 g/t, 7m @ 9.0 g/t and 2m @ 3.7 g/t”. Barra Resources subsequently completed a 20 m x 25 m drill out to 240 m in depth, combined with a detailed feasibility study, culminating in the commencement of mining operations in August 2001. Barra Resources also completed RC drill programs at three prospects within the First Hit Project leases, referred to as First Hit North, First Hit South and Clarkes Well. Minor gold mineralisation was intersected in a small number of holes, but no further exploration was completed. The leases have since been owned byseveral companies andprivate operators without much additional exploration. |
| Geology | Deposit type, geological setting and style of mineralisation | Regional Geology The area of interest lies on the 1:100,000 Riverina geological sheet 3038 (Wyche, 1999). The Mt Ida greenstone belt is a north- striking belt of predominantly metamorphosed (upper greenschist-amphibolite facies) mafic and ultramafic rocks that form the western boundary of the Eastern Goldfields geological terrane. The major structure in this belt is the Mt Ida Fault, a deep mantle tapping crustal suture that trends N-S and dips to the east. It marks the western boundary of the Kalgoorlie Terrane (~2.7 Ga) of the Eastern Goldfields Province against the Barlee Terrane (~3.0 Ga) of the Southern Cross Province to the west. To the east the belt is bounded by the Ballard Fault, a continuation of the strike extensive Zuleika Shear. The Mt Ida belt is widely mineralised, predominantly with discordant vein gold deposits. Associated element anomalism typically includes copper and arsenic but neither have been identified in economic concentrations. There is some nickel sulphide mineralisation associated with the komatiite component of the supracrustal rocks and the area includes a locally significant beryl deposit sporadically mined for emeralds. In the Riverina area the outcrop position of the Ida Fault is equivocal, and it is best regarded as a corridor of related structures with an axis central to the belt. The Riverina and First Hit Project area dominantly comprises metabasalts and metadolerites of tholeiitic parentage with lesser metagabbros and komatiites. Small post-tectonic granitoids intrude the sequence with locally higher-grade metamorphic conditions. Structurally, the dominant features are north-striking, east-dipping reverse faults and associated anastomosing strain zones. A conjugate set of late brittle structures striking NE and NW is also evident. The mineralisation exploited to date has typically been narrow mesothermal anastomosing veins. These frequently have strike and dipdimensions able to sustain small high-grade miningoperations. |

| Local Geology The local geology of the First Hit Project area comprises north striking ultramafics, komatiites and peridotites with some sediments in the eastern part of the block. To the west there is a metabasalt unit including a prominent gabbro and further west again more peridotite with amphibolite. The general strike trend drifts to the north-northwest then back to north. The sequence includes a small felsic intrusive west of the Emerald workings and a zone of felsic schists within the eastern ultramafics. Felsic intrusives occur in the northwest corner. The local strike fabric trends north then north-northeast. The First Hit mineralisation occurs as a quartz lode varying to 4 m in thickness dipping at 70º to the east. The lode is hosted in biotite- carbonate schist within metabasalt and plunges to the south at around 50º. Numerous shafts, prospecting pits and costeans exist on the tenements and recorded production for the First Hit and First Hit North areas in the period 1930-1974 was ~7478 oz Au from 6091 tonnes mined. The First Hit North workings are 130 m further to the north-northeast. References Wyche, S.1(1995). Geology of the Mulline and Riverina 1:100,000 Sheets.

| 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: • easting and northing of the drill hole collar • elevation or RL (Reduced Level – elevation above sea level in metres) of the drill hole collar • dip and azimuth of the hole • down hole length and interception depth • hole length. 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 clearly explain why this is the case. |
A summary of the relevant drillhole information has been included in the body of the report. |
| Data aggregation methods |
In reporting Exploration Results, weighting averaging techniques, maximum and/or minimum grade truncations (eg 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. |
No top cuts have been applied to the reporting of the assay results. Intersection lengths and grades for all holes are reported as down-hole length-weighted averages of geologically selected intervals. |
| 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 (eg ‘down _hole length, true width not known’). _ |
The drilling programs at the First Hit deposit reported herein are variably oblique to the true width of the deposit. All drill holes are reported as down hole widths as the true width cannot be determined. |

CSA Global undertook Principal Component Analysis on the geochemical data generated from air core programs across the tenement. Principal component analysis (PCA) simplifies the complexity of geochemical data while retaining trends and patterns. It does this by transforming the data into fewer dimensions, which act as summaries of features. A PCA plot shows clusters of samples based on their similarity. CSA Global and Viking Mines have utilised the historical geochemistry described in Section One to provide guidance in interpreting anomalism in prospects where anomalism has been defined in 2021 aircore geochemistry.

3D modelling of the regional geology and structure at the tenement scale is in progress. The evaluation of all geochemical data is being evaluated to design additional exploration activities on the exploration tenements which may include geochemistry, RC and diamond drilling. Drill programme planning to immediately follow up on the step out hole VDD016 to test for new shoot potential, including additional systematic step out traverses to the north along the Frist Hit structural trend Programme design to test the depth extensions of the First Hit mineralisation. In addition, assessment of the effectiveness of historical RC drilling in light of recent observation on poor sampling practices (4m composites) for narrow vein high-grade gold targets will commence. Incorporation of assay data into a regional structural model to define new targets for follow up and to provide support for the 4 target areas identified from the Air-Coreprogramme. |
