Lode interpretation models demonstrate the potential for remaining unmined mineralisation at the historical First Hit underground (UG) mine.
-
Diamond Drill (DD) programme planning has progressed, and the rig is due onsite the week commencing 15[th] February 2021.
Viking’s CEO Julian Woodcock commented: “With the ongoing 3D review of the historical data collected from the First Hit mine, we have identified further high-grade drilling intercepts outside of the recorded mined areas. These results reaffirm the potential offered by this mineralised system and I am eagerly anticipating getting the drill programme underway and obtaining the first drill core from this high-grade gold project in more than 18 years.”
ANNOUNCEMENT DETAILS
Viking Mines Limited (ASX: VKA) (“Viking” or “the Company”) is pleased to announce that through the ongoing collation of data and digitising of historical mining records, further high-grade historical drilling intercepts have been identified, outside of the known limits of the historical mining area. In addition, several intercepts have been identified outside of the currently defined limits of mineralisation indicating that the fertile structures continue to the North and South.
DATA REVIEW
Lode Interpretation
All drilling and UG face sampling data are being assessed in 3D, to produce an updated interpretation of the mineralisation at First Hit. Through this assessment, Viking has determined 3 main gold bearing lodes that characterise the majority of the mineralisation.

Kylie Lode – Separately identified as the Evans and Kylie Lodes near surface and merge to form the Kylie lode at depth (Figure 1).
-
Owens Lode – Forms in the footwall (FW) to the Kylie Lode as a splay from the main structure (Figure 2). A ‘cross-lode’ connects the two at the 310 RL and has been mined in a different orientation indicating potential for other orientations of mineralisation.
-
Ida Splay (Lode) – Forms in the hanging wall (HW) to the Kylie lode as a splay from the main structure (Figure 3).
Plans of the 390, 310 and 230 levels are shown on the long sections to illustrate the lode positions and interactions relative to one another and what areas have been mined and the potential for remaining mineralisation.
Underground Mine Workings
An initial 3D model of the underground mine workings at First Hit has been compiled by CSA Global and the Company to assist with drill programme planning and to minimise the risk of drilling into mining voids. The model was created by reviewing and digitising all the available historical data obtained from old mine records and the publicly available First Hit Final Mine Report 2002 (issued by Barra Resources to the Department of Mines, Industry, Regulation and Safety - DMIRS). The extents of these workings have been plotted on long sections below for each of the lodes encountered at First Hit.

Drilling Data
All drilling data that pierces these lode models are plotted on the long sections as gram metre intervals. Overlaying the UG mined workings has identified areas at First Hit where mineralisation has not been mined. Values previously reported by the Company in ASX release dated 26[th] November 2020 are shown on the long sections alongside newly identified intercepts which are outside of limits of the known workings. Evidence of the structure continuing to the north and south is also present outside the mineralised position of the lodes and shown in the figures. All the intercepts reported are listed in Appendix 1.
NEXT STEPS
Ongoing geological review of the historical data is underway, with the objective of:
-
Refining the impending phase 1 DD programme.
-
Assessing the potential of the unmined portions of the First Hit mine.
-
Determining areas of mineralisation which are not closed off and lack sufficient drilling.
-
Identifying key geological structures which will influence controls to mineralisation.
-
Determining any association between rock type and alteration with mineralisation.
Additional data related to the historically mined workings has not yet been fully captured. Assessment and acquisition of these data is ongoing and will continue to inform the geological model. When combined with the results of the impending drill programme these data will help determine the best areas to focus future phases of drilling and predict the potential for additional mineralised shoots. Data currently being captured are:
-
Detailed geological information and assay data off face mapping sheets historically collected at ~3m intervals throughout the mine.
-
Underground survey data of ore mined in the backs (roof) of underground drives.
Viking is also in the process of trying to source additional key datasets and maps of the UG development which were completed by the mine geologists as the mine was developed. This information will further provide valuable insights to help gain a greater understanding of the mineralisation at First Hit and will assist in planning future exploration activity.
This announcement has been authorised for release by the Board of the Company.

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 is 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 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)
-
3m at 77.6g/t Au from 224.0m (BFH030)
-
4m at 26.1g/t Au from 58.0m (BFH005)
The Project area is well serviced by infrastructure and is located 50km west of the sealed Goldfields highway and the township of Menzies. It is within 100km radius of 4 operating Gold Processing Plants, the nearest being the Davyhurst Mill 50km to the south, owned and operated by Ora Banda Mining (ASX:OBM). The nearest operating gold mine, owned by OBM is the Riverina open pit, located 8km south of the First Hit gold mine.
The Company also has projects located in Ghana and Mongolia. Viking is currently undergoing legal proceedings to secure an outstanding payment of US$ 5 million, associated with the sale of the Akoase project in Ghana.

| Sampling techniques |
Nature and quality of sampling (e.g. cut channels, random chips, or specific specialised industry standard measurement tools appropriate to the minerals under investigation, such as downhole gamma sondes, or handheld XRF instruments, etc.). These examples should not be taken as limiting the broad meaning of sampling. |
Surface Geochemistry 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. 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 with percussion and core drilling of holes up to 346 metres deep below surface has been undertaken over time over the First Hit Project area mineralisation. And 21 RC holes 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. Core from drilling 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). 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. |
| Include reference to measures taken to ensure sample representivity and the appropriate calibration of any measurement tools or systems used. |
The entire RC sample was extracted prior to subsampling at surface next to the 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. |

The breakdown in drilling method yielding each sample type is included in the table below. Sample preparation 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). |

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. |
| Measures taken to maximise sample recovery and ensure representative nature of the samples. |
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. |
|
| 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. |
Insufficient information on sample recovery is available to establish whether a relationship between sample recovery and grade exists. |
|
| 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. |
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 hangingwall, 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 the reporting. |
| Whether logging is qualitative or quantitative in nature. Core (or costean, channel, etc.) photography. |
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. |

| The total length and percentage of the relevant intersections logged. |
The total length of all drilling was geologically logged. | |
| Subsampling techniques and sample preparation |
If core, whether cut or sawn and whether quarter, half or all core taken. |
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. |
| If non-core, whether riffled, tube sampled, rotary split, etc. and whether sampled wet or dry. |
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-samplingwas undertaken usingthe spear samplingmethod |
|
| For all sample types, the nature, quality and appropriateness of the sample preparation technique. |
The Competent Person considers these methods appropriate for this style of mineralisation. |
|
| Quality control procedures adopted for all subsampling stages to maximise representivity of samples. |
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. |
|
| 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. _ |
Barminco Pty Ltd 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. |
|
| Whether sample sizes are appropriate to the grain size of the material being sampled. |
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. |
|
| Quality of assay data and laboratory tests |
The nature, quality and appropriateness of the assaying and laboratory procedures used and whether the technique is consideredpartial or total. |
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. |
| 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. |
No non-destructive tools or devices are recorded as being used. | |
| 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. |
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. |
|
| Verification of sampling and assaying |
The verification of significant intersections by either independent or alternative company personnel. |
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. |
| The use of twinned holes. | 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. |

| Documentation of primary data, data entry procedures, data verification, data storage (physical and electronic) protocols. |
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. |
|
| Discuss any adjustment to assay data. |
No adjustments or calibrations have been made to any assay data. | |
| Location of data points |
Accuracy and quality of surveys used to locate drillholes (collar and downhole surveys), trenches, mine workings and other locations used in Mineral Resource estimation. |
All drill hole collars were surveyed by differential global positioning system (DGPS) or by the mine operations survey equipment. The following extract from the 2001 First Hit Mine Ore Resource and Mining report states the following: Down hole surveying of drill holes was 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 helpalleviate thisproblem, but no consistent results were achieved. |
| Specification of the grid system used. |
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. |
|
| Quality and adequacy of topographic control. |
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. |
|
| Data spacing and distribution |
Data spacing for reporting of Exploration Results. |
The majority of the data on the tenements is surface geochemistry which are adequate for defining anomalies for future exploration. |
| 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. |
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. |
|
| Whether sample compositing has been applied. |
Sample composting was applied in initial exploration drilling at the First Hit Project and always followed upbydetailed samplingat 1 m interval, or less for core drilling. |
|
| 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. |
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. |
| 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. |
No relationship has been noted between drillhole orientation and mineralisation. |

Red Dirt Mining are not aware of any material 3rd party interests or royalties. Native Title, Historical sites and Wilderness Archaeological and ethnographic studies were undertaken for M30/99 prior to further development in 2001. These studies involved an examination of the existing ethnographic data base pertaining to the mining area and an examination of known ethnographic site distribution. The studies concluded that it was unlikely that the developments will impact any sites of Aboriginal significance. This information was submitted to the Department of Aboriginal Affairs. A recent search of the Department of Aboriginal Affairs (DAA) Heritage Inquiry System indicates there are no registered Aboriginal Heritage Sites identified within any tenement covered under this MCP (DAA 2019).

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, rangingfromgold-onlyassays to 42 elementgeochemistry. |

| 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 by several companies and private 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 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.

| 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 Appendix 1 in this 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. |
All drilling exploration assay results are reported as weighted averages. |
| 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. |
| Diagrams | Appropriate maps and sections (with scales) and tabulations of intercepts should be included for any significant discovery being reported These should include, but not be limited to a plan view |
All appropriate maps and plans are included in the body of the report. |

| Balanced reporting |
Where comprehensive reporting of all Exploration Results is not practicable, representative reporting of both low and high grades and/or widths should be practiced to avoid misleading reporting of Exploration Results. |
The assay intervals reported in Appendix 1 contain both the high grade and low-grade assay intervals. |
| Other substantive exploration data |
Other exploration data, if meaningful and material, should be reported including (but not limited to): geological observations; geophysical survey results; geochemical survey results; bulk samples – size and method of treatment; metallurgical test results; bulk density, groundwater, geotechnical and rock characteristics; potential deleterious or contaminating substances |
All information considered by the competent person to be of a material nature has been included in the body of the report. |
| Further work | The nature and scale of planned further work (eg tests for lateral extensions or depth extensions or large-scale step-out drilling). Diagrams clearly highlighting the areas of possible extensions, including the main geological interpretations and future drilling areas, provided this information is not commercially sensitive. |
Exploration programs are currently being designed to test the up dip, lateral and down dip extensions of the mineralisation at the First Hit deposit. Regional multielement geochemical programs are being designed to supplement the existing geochemistry, however, advances in geochemical analysis mean that that lower level detection limits can be obtained for more elements than in previous geochemical surveys. Previous geophysical data is being obtained with a view to reprocessing the data. |
