ASX ANNOUNCEMENT
VIKING RECEIVES HIGH-GRADE RESULTS IN FIRST ASSAYS FROM 72-HOLE RC DRILLING PROGRAMME
-
Reverse Circulation (RC) drilling programme completed with 72 holes for 6,723 metres drilled over 4 target areas
-
First assay results received for 7 holes, delivering high-grade, near-surface intercepts, with key results including:
o VKRC0023: 2m at 9.67g/t Au from 26m
-
VKRC0066: 2m at 4.26g/t Au from 75m
-
First set of results support the potential for an additional mineralised shoot 720m north of the historic, high-grade First Hit Gold Mine
-
All samples shipped to the laboratory over 7 consignments
-
Gold nuggets and gold in quartz associated with historic workings at Jana’s Reward target found, with additional hole planned and drilled to test below old workings
Viking Mines Limited (ASX: VKA) (“ Viking ” or “ the Company ”) is pleased to report completion of its 72 hole, 6,723m RC Drilling Programme at the flagship First Hit Project ( “First Hit“ or “ the Project ”), 50km west of Menzies in the WA Goldfields.
Viking is also pleased to announce the first set of assay results have been received for 7 of the 72 holes completed (~10% of the programme). These first results are from the First Hit North target area and, importantly, confirm the presence of high-grade gold mineralisation 720m north of the historic high grade First Hit gold mine.
Hole VKRC0023 returned 2m at 9.67g/t Au from 26m downhole and hole VKRC0066 returned 2m at 4.26g/t Au from 75m (located 40m to the south and 40m downdip of hole VKRC0023). Whilst many results are still pending and interpretation is required, the first set of results support the potential for a mineralised shoot 720m north of the historic First Hit gold mine (Figure 1). Additional assays received also confirmed the presence of gold 220m north of the historic First Hit mine workings with 2 additional potential shoot positions now identified outside of the limits of the First Hit mine workings.
In total, the 72 hole, 6,723m drill programme tested 4 targets, with visible gold identified in 5 drillholes to date[1&2] . Included in this total are 7 additional holes for 724m that were planned and completed to test additional areas at the First Hit North and Jana’s Reward targets which were identified as drilling progressed.
The additional holes were planned based on the visible gold seen at First Hit North. The visible gold gave the exploration team the confidence for an additional drill traverse testing 300m north of the planned limits of drilling (Figure 2). Additionally, based on gold nuggets and gold in quartz (Figure 3 & Figure 4) identified in historic workings at Jana’s Reward, the Company planned and drilled one hole to 70m. Assay results for these holes are pending.
Commenting on the completion of the RC drilling programme and receipt of highgrade results from the first set of assays, Viking Mines Managing Director & CEO Julian Woodcock said , “The first set of assay results from our extensive 72-hole, 6,723m

drill programme highlight the excellent potential of our First Hit Project to host multiple mineralised high-grade shoots.”
“Viking has been consistently executing an exploration strategy focused on identifying narrow-vein, high-grade shoots and holes VKRC0023 and VKRC0066 provide the Company with exposure to previously undiscovered mineralisation.”
“We are still in the early stages of exploring First Hit and we are buoyed by the results we have received throughout 2021. Importantly, with over 90% of drillhole assay results from this programme still to be returned, these results will provide critical information to direct future exploration plans around these exciting new prospects.”
ASSAY RESULTS
First Hit North
Assay results have been received for 735 samples (exc. QAQC) at the time of this release.
This represents only 7 drillholes (26%) of the 27 holes completed at the First Hit North target (Figure 1 & Figure 2) and <10% of the 72 holes drilled in total across the 4 target areas. The results include all the samples for the 5 drillholes where visible gold has been observed at the expected target intervals[1&2] . Significant results received to date are:
720m North of the First Hit historic mine workings (Figure 1 & Figure 2):
-
VKRC0023: 2m at 9.67g/t Au from 26m
-
VKRC0066: 2m at 4.26g/t Au from 75m
These results confirm the presence of high-grade gold and the potential for a newly discovered high-grade shoot 720m North of the historic First Hit mine. Importantly, these results also support the observation of visible gold at the target intervals.
220m North of the First Hit historic mine workings (Figure 1 & Figure 2):
-
VKRC0008: 1m at 4.56g/t Au from 64m
-
VKRC0009: 1m at 2.55g/t Au from 98m
These results confirm the continuity of the First Hit structure from the historic workings and compare with the variable nature of the mineralisation as previously observed at First Hit.
Further assessment of the samples received is required, including additional Photon assay analysis on the remaining portion of the high-grade samples to determine the variability due to the relatively coarse nature of the gold seen in the RC chips. This will determine if there is a significant nugget effect occurring. A nugget effect is where repeat assays have a much higher or lower grade due to the nuggety nature of the mineralisation which is common with high-grade narrow vein deposits.
The frequency and occurrence of high-grade gold identified 720m North of the historic First Hit mine workings demonstrates the potential for a high-grade shoot to be defined with further drilling. At 80m drill spacing, a single high-grade result leaves sufficient untested strike length either side of the intercept to host a mineralised shoot up to 160m in length (distance to the adjoining drill sections). The planning of additional holes in the field (VKRC0066 & VKRC0067) to reduce the drill spacing and the subsequent intersection of gold in hole VKRC0066 confirms the continuity of a potential shoot. On receipt of the remaining assays for First Hit North, follow up drill programmes will be assessed.

RC PROGRAMME STATUS
Drilling Summary
The planned RC drill programme to test multiple targets at the First Hit Project has been completed and the drilling crew has demobilised off site. Additional holes were planned in the field based on observations made whilst drilling advanced. On completion, the programme has totalled 72 holes for 6,723 metres (Table 1).
Table 1; First Hit Project targets tested as part of the 2021 RC drill programme with number of holes and metres drilled detailed
| Prospect | No Holes | Metres |
|---|---|---|
| First Hit North | 30 | 2,437 |
| First Hit North additional traverse | 6 | 654 |
| First Hit South | 14 | 1,669 |

| Jana’s Reward | 11 | 990 |
| Jana’s Reward additional hole testingold workings | 1 | 70 |
| TOTAL | 72 | 6,723 |
The planned RC programme took 44 drilling days to complete, at an average of 153 metres per drilling day against a budget of 38 drilling days at 180m per day. Two breakdowns during the programme and other technical issues pushed out the completion date by 4 weeks from mid-November to mid-December.
Additional Drilling
Jana’s Reward – Whilst undertaking drilling at the Jana’s reward prospect, shallow historic prospectors workings were identified in the NW corner of the target area. The workings are focussed on a ~1m wide E-W quartz vein which dips to the south at approximately 40[o] and has been mined near surface. Surface prospecting near the old workings discovered 11 nuggets totalling ~1g of gold nuggets (Figure 3) and gold in quartz (Figure 4), confirming the presence of coarse gold.
With the confirmation of coarse gold and the perpendicular orientation of the veins to the First Hit mineralisation, the Company planned and drilled one hole to 70m depth which was drilled towards the NNE.
The objective of this drillhole was to test the mineralisation for:
-
a) Continuity to depth from surface
-
b) Obtain a sample for analysis
-
c) Confirm the dip and orientation
Drilling was completed as planned and all 3 objectives met. A 1m quartz vein was intercepted at 49m downhole associated with silica alteration and sulphide mineralisation from 47m to 51m. The intercept of the vein supports the interpretation and modelling based on the surface observations of the old workings and confirms the vein continues to a vertical depth of ~33m and remains open.

First Hit North – Drill targeting has been successful in confirming that the First Hit structure extends North from the First Hit Mine up to 720 metres along strike with the discovery of visible gold in hole VKRC0023[1] and the high-grade assay of 2m at 9.67g/t Au.
Based on the visible gold observed and the potential for additional shoots to exist on the First Hit structure, the company decided to extend the drill programme out a further 300m beyond the original planned limits of drilling to test for the continuity of the structure (Figure 2).
ASX:VKA | vikingmines.com

A section line traverse was designed across the First Hit structure location and to test a coincident gravity low, magnetic high (Figure 5) and contact between basalt and ultramafic host rocks. A total of 6 holes for 654m was planned and subsequently drilled as a heel-totoe traverse. Drilling identified a thicker weathering (regolith) profile which could explain the gravity low. Multiple rock types were encountered and zones of shearing which could indicate the potential continuity of the structure. Samples have been shipped to the laboratory and results will be required to determine if gold bearing mineralisation extends to >1.1km North from the historic First Hit mine (Figure 2).
Lab Turnaround and Results Forecast
All samples from drilling have been collected and despatched from site to the Intertek laboratory in Kalgoorlie. A total of 7 consignments have been delivered to the laboratory with the first delivery occurring on 15 October 2021 and the last delivery on 20 December 2021. The laboratory has been experiencing increasing delays in part due to COVID vaccine mandates impacting staff availability. Based on the current turnaround times being experienced and the timing of the delivery of samples to the laboratory, it is expected that all results will be received by late in the March quarter FY22 (subject to no further delays by the lab).
NEXT STEPS
Following completion of the field activities component of the drill programme, the following activities are underway on the project:
-
Loading of all drilling data and verification in 3D software as assays are returned
-
Commencement of 3D modelling of the mineralised structures observed in drilling
-
Photon assay technique to be applied on identified mineralised zones to determine if any coarse gold is present which could increase the variability of grade observed in the assay results (Photon assay techniques vs fire assay)
-
Selection of key samples for multielement analysis to assist in geological interpretation of host rock types and potential vectoring to high grade mineralisation and targeting

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 [257 x 70] intentionally omitted <==
==> 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 byshallow 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 sampling was treated similarly to a drill hole although typically undertaken 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 Current VKA 2021 RC Exploration Drilling and Sampling RC samples are collected at the drill rig during the drilling process. Samples are collected from a cone splitter by placing a calico bag across the two sample apertures as well as a bucket under the splitter to collect the reject. Samples are collected every metre drilled with the reject being dumped on the ground and the two calicoes being placed on top. Each of the calico sample bags are between 2 and 3kg in weight with one being collected for assay at Intertek laboratories in Kalgoorlie for 50g fire assay analysis. 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. |

| 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 Current VKA 2021 RC Exploration Drilling and Sampling RC sample analysis: RC drilling was used to obtain a 1m composite sample from which 2-3kg is pulverised to produce a 50g charge for fire assay. Selective 1m samples are collected for multi-element analysis. The Competent Person considers these samplingand analytical methods appropriate for this style of mineralisation. |

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.

| Drill sample recovery |
Method of recording and assessing core and chip sample recoveries and results assessed. |
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 Current VKA 2021 RC Exploration Drilling and Sampling RC drilling recoveries are visually estimated and recorded as part of geological logging process. The Competent Person considers the recoverymeasurement 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 Current VKA 2021 RC Exploration Drilling and Sampling RC drilling sample recovery is 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 Current VKA 2021 RC Exploration Drilling RC 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 there to be a potential sampling bias related to the recovery/sampling at the First Hit mineralisation with RC drilling, however the method is suitable for exploration drilling. |
||
| 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.

| 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 Current VKA 2021 RC Exploration Drilling and Sampling RC 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, rock fabric and the presence of minerals potentially related to mineralisation including quartz and sulphides.

Historical Information 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 Current VKA 2021 RC Exploration Drilling and Sampling Duplicate sub sampling has been applied to the current RC drill programmes (see details below). Selective panning for gold to assist with targeting was also undertaken. 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 Current VKA 2021 RC Exploration Drilling and Sampling Field duplicates were collected from the cone splitter for every metre drilled. The second sample was selected as a duplicate on an ad-hoc basis either by trying to obtain a roughly 1:25 sample ratio or if the geologist identified a particular sample to be used as a duplicate.

| Criteria | JORC Code explanation | Commentary | |
| 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 Current VKA 2021 RC Exploration Drilling and Sampling–Surveys The collar positions have been surveyed using a differential GPS with an accuracy of +/-0.5m once drilling of the planned programme was completed. The downhole azimuth and dip were surveyed using a Reflex Easy Gyro tool or an Axis Mining Technology Champ Gyro tool with an accuracy of +/- 1 degree for the azimuth and +/-0.1 degrees for the dip. The Competent Person considers the survey processes 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 Current VKA 2021 Grid datum 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.

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 Current VKA 2021 RC Exploration Drilling and Sampling The spacingof the RC drillingis considered appropriate for this type of deposit and no resources are currentlybeingestimated. |

| 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 Current VKA 2021 RC Exploration Drilling and Sampling No sample compositing has been applied for RC drill samples. The Competent Person considers the samplingto 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 Current VKA 2021 RC Exploration Drilling and Sampling RC drilling is predominately orthogonal to the strike of the structural trends and mineral system. Understanding the geometry of the mineralised trends is managed through incorporating as much of the underground mapping and historical drilling as possible as well as regional data sets. Additionally, all RC holes are oriented to understand and measure the variability of structures and mineralisation. The Competent Person considers theprocesses for 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 Current VKA 2021 RC Exploration Drilling and Sampling At this stage of exploration, RC drilling is considered by the Competent Person not to have introduced a sampling bias. However, as drilling continues, this will need to be reviewed as coarse gold has been observed in core and RC drilling which may require further review. |

| 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 Current VKA 2021 RC Exploration Drilling and Sampling Samples derived from the RC drilling were collected and stored by site personnel at a designated lay-down area on site. These samples were transported to Intertek laboratories in Kalgoorlie by site personnel or Pitbull transport. The Competent Person considers theprocesses for sample securityas appropriate. |

| 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 Resources 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. |

| Criteria | JORC Code explanation | Commentary | |
| 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 dip dimensions able to sustain small high-grade mining operations. 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.

| Further assessment of RC samples received is required, including additional testwork on the remaining samples to determine the variability due to the relatively coarse nature of the gold seen in the RC chips. Additional assaying will be completed on the samples to see if there is a significant nugget effect. Execution of the 2021 RC drill programme consisting of 72 holes for 6,723m has been completed, however results are still being obtained and interpreted. This drill programme involved testing around 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. Three other target areas were also tested including First Hit South, Twin Peaks, and Jana’s Reward. 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 and be tested through the completion of the 2021 RC drilling programme. 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. |
