Osborne JV Exploration Update

Artemis Resources Limited ("Artemis" or the "Company") (ASX:ARV, AIM:ARV, Frankfurt: ATY, US OTCQB: ARTTF) is pleased to provide an update on the maiden drill program at the Osborne Nickel Prospect, a joint venture project owned 100% by Artemis with GreenTech Metals Ltd (ASX:GRE) ("GreenTech"), the project manager,  earning up to 51%.

Artemis and its JV partner and Project Manager GreenTech announced on 30 June 2022 that it had commenced the first reverse circulation ("RC") drill hole designed to test the shallowest portion of the Osborne nickel sulphide target. The drill program to test the Osborne nickel target consisted of two holes for a total 598.5m, including 198.5m core drilling. Drilling successfully intersected the modelled electromagnetic (EM) conductor in the first RC drill hole with sulphides visually observed in RC chips over a 7m interval from 173m depth.  In consultation with technical consultant Newexco, a decision was taken by GreenTech to utilise the second RC drill hole as a pre-collar for a diamond drill 'tail'. The diamond drill core provided greater detail of the host rocks and the nature of the sulphide mineralisation associated with this conductive horizon.

RC samples from the first drill hole were sent to the ALS laboratory in Perth for multi-element analysis. Although the nickel and copper potential of the sulphides was initially confirmed by handheld pXRF analyser, no significant nickel or copper results were reported in the laboratory analyses. Similarly, no significant nickel or copper mineralisation was identified in the drill chips and core from the second drill hole using a pXRF analyser. Following a review of all the drilling and geophysical data, Newexco has recommended that further geophysical interpretation be undertaken prior to any follow-up drill programs at Osborne.

JORC Code, 2012 Edition - Table 1 report template

Section 1 Sampling Techniques and Data

(Criteria in this section apply to all succeeding sections.)

Criteria	JORC Code explanation	Commentary
Sampling techniques	· Nature and quality of sampling (eg cut channels, random chips, or specific specialised industry standard measurement tools appropriate to the minerals under investigation, such as down hole gamma sondes, or handheld XRF instruments, etc). These examples should not be taken as limiting the broad meaning of sampling. · Include reference to measures taken to ensure sample representivity and the appropriate calibration of any measurement tools or systems used. · Aspects of the determination of mineralisation that are Material to the Public Report. · In cases where 'industry standard' work has been done this would be relatively simple (eg 'reverse circulation drilling was used to obtain 1 m samples from which 3 kg was pulverised to produce a 30 g charge for fire assay'). In other cases more explanation may be required, such as where there is coarse gold that has inherent sampling problems. Unusual commodities or mineralisation types (eg submarine nodules) may warrant disclosure of detailed information.	· Samples were collected at one metre intervals in calico bags from a cyclone and cone splitter attached to a Reverse Circulation (RC) drill rig. The remainder of the sample (reject) was collected in green mining bags. · Samples assessed as prospective for nickel mineralisation were taken in pre-numbered calico bags as single-metre consecutive interval. A typical composite sample weighs between 2 and 3kg. · A Bruker S1 Titan portable XRF was used to determine prospective intervals. · Certified Reference Materials (CRM) and blank material were alternatively inserted approximately every 25 samples. · Samples were analysed by ALS Global in Perth using a 4-acid digest with MEICP-61 finish for 34 elements.
Drilling techniques	· Drill type (eg core, reverse circulation, open-hole hammer, rotary air blast, auger, Bangka, sonic, etc) and details (eg core diameter, triple or standard tube, depth of diamond tails, face-sampling bit or other type, whether core is oriented and if so, by what method, etc).	· Two Reverse Circulation (RC) drill holes, the second with a NQ diamond core tail added, were completed on tenements E47/3719 using a face sampling percussion hammer with 140mm bits. Equipment used was a Austex ED250 drill rig fitted with a Sullair Compressor on board booster and auxiliary unit fitted with an Atlas Copco Y1260 compressor. · Holes were drilled at dip angles of -68° and -75° and (magnetic) azimuth angles of 199° and 192° in order to orthogonally intercept the modelled EM plates
Drill sample recovery	· Method of recording and assessing core and chip sample recoveries and results assessed. · Measures taken to maximise sample recovery and ensure representative nature of the samples. · Whether a relationship exists between sample recovery and grade and whether sample bias may have occurred due to preferential loss/gain of fine/coarse material.	· The geologist visually assessed and recorded drill sample recoveries during the program, and these were overall very good. · RC holes were collared with a well-fitting stuff box to ensure material loss to the outside return was minimised. Drilling was undertaken using an auxiliary compressor and booster to keep the hole dry and lift the sample to the sampling equipment. Drill cyclone and splitter were cleaned as required and after each hole to minimise down hole or cross-hole contamination. · There were issues with air circulation which resulted in intervals of the holes being drilled and returning wet samples. · No relationship between sample recovery and grade has been undertaken.
Logging	· Whether core and chip samples have been geologically and geotechnically logged to a level of detail to support appropriate Mineral Resource estimation, mining studies and metallurgical studies. · Whether logging is qualitative or quantitative in nature. Core (or costean, channel, etc) photography. · The total length and percentage of the relevant intersections logged.	· All drill holes have been geologically logged for lithology, weathering, alteration, mineralisation and other features of the samples using sieved rock chips from the reject material. · Data was entered in an appropriate database and is of detail suitable for incorporation (if required) into a mineral resource estimation. · All drill holes were logged in full.
Sub-sampling techniques and sample preparation	· If core, whether cut or sawn and whether quarter, half or all core taken. · If non-core, whether riffled, tube sampled, rotary split, etc and whether sampled wet or dry. · For all sample types, the nature, quality and appropriateness of the sample preparation technique. · Quality control procedures adopted for all sub-sampling stages to maximise representivity of samples. · Measures taken to ensure that the sampling is representative of the in situ material collected, including for instance results for field duplicate/second-half sampling. · Whether sample sizes are appropriate to the grain size of the material being sampled.	· The sample preparation technique carried out in the field is considered industry best standard practice and was completed by the geological consultant. · RC samples are collected via a cone splitter. Geological logging of RC chips is completed at site with representative chips being stored in drill chip trays. · Consecutive single metre sample splits were collected and placed into a pre-numbered calico bag. · The samples were then sent to ALS Global for sample preparation and analysis. Where they will be sorted, dried and pulverised (up to 3kg) to achieve 85% passing 75μm to produce a homogenous representative for analysis. · Individual samples were assayed for a suite of 34 elements including nickel related analytes as per the laboratory's procedure for a 4-acid digestion followed by Inductively Coupled Atomic Emission Spectral analysis. · The sample sizes are considered to be appropriate to correctly represent base metal sulphide mineralisation and associated geology based on the style of mineralisation (massive and disseminated sulphides), the thickness and consistency of the intersections and the sampling methodology. · The NQ core from the second drill hole was not split, sampled or assayed as field analysis using a Pxrf revealed no mineralisation that warranted the laboratory analysis of core samples.
Quality of assay data and laboratory tests	· The nature, quality and appropriateness of the assaying and laboratory procedures used and whether the technique is considered partial or total. · For geophysical tools, spectrometers, handheld XRF instruments, etc, the parameters used in determining the analysis including instrument make and model, reading times, calibrations factors applied and their derivation, etc. · Nature of quality control procedures adopted (eg standards, blanks, duplicates, external laboratory checks) and whether acceptable levels of accuracy (ie lack of bias) and precision have been established.	· Assaying was completed by a commercial registered laboratory with standards and duplicates reported in the sample batch. In addition, nickel Certified Reference Materials (CRM) were inserted into the batch by the geological consultant at a rate of 1:50 samples. · No geophysical tools were used to determine any reported element concentration. · Select intervals were measured/estimated on a metre basis using a Bruker S1 Titan portable XRF with a reading time of 60 seconds per sample.
Verification of sampling and assaying	· The verification of significant intersections by either independent or alternative company personnel. · The use of twinned holes. · Documentation of primary data, data entry procedures, data verification, data storage (physical and electronic) protocols. · Discuss any adjustment to assay data.	· Assay, sample ID and logging data are matched and validated using filters in the drill database. · Assay results are provided by the laboratory to GreenTech in a csv file format and then validated and entered into the database managed by an external contractor. · Primary geological and sampling data were recorded on hard copy and digitally and were subsequently transferred to a digital database where it was validated by experienced database personnel assisted by the geological consultant. · There has been no validation and cross checking of laboratory performance at this stage. · Twinned holes have not been used in this program.
Location of data points	· Accuracy and quality of surveys used to locate drill holes (collar and down-hole surveys), trenches, mine workings and other locations used in Mineral Resource estimation. · Specification of the grid system used. · Quality and adequacy of topographic control.	· Drill hole collars were initially located and pegged using a handheld GPS with an expected accuracy of +/-3m for easting, northing and elevation. · The rig was aligned using compass and gyro · All drill holes were surveyed using a north seeking gyro and downhole records taken every 5m at the completion of each hole by the drill contractor. · The grid system used is GDA94, MGA zone 50.
Data spacing and distribution	· Data spacing for reporting of Exploration 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. · Whether sample compositing has been applied.	· Drill holes were completed at a select geophysical target on tenement E47/3719 · The spacing and distribution of holes is not relevant to this drilling program which is at the exploration stage rather than definition drilling. · The drilling to date at the Project is not sufficient to establish the degree of geological and grade continuity to support the definition of Mineral Resource and Reserves and the classifications applied under the 2012 JORC code. · The RC portions of the drill holes were sampled at 1 metre intervals down hole.
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. · 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.	· The drill holes were planned to intersect the modelled geophysical target zones at a near perpendicular orientation. However, the orientation of key structures may be locally variable and any relationship to mineralisation has yet to be identified. · No orientation-based sampling bias has been identified in the data to date.
Sample security	· The measures taken to ensure sample security.	· All samples collected during the program were transported by Newexco the geological consultant to an independent third-party commercial transport contractor who delivered the samples to ALS Global laboratory in Perth for submission and analysis. · Sample security was not considered a significant risk to the project, however only employees of Newexco were involved in the sampling and sample custody in a remote area. No specific measures were taken o ensure sample security beyond the normal chain of custody for sample submission.
Audits or reviews	· The results of any audits or reviews of sampling techniques and data.	· No formal audits or reviews have been conducted on sampling technique and data to date.

 

 

Section 2 Reporting of Exploration Results

(Criteria listed in the preceding section also apply to this section.)

Criteria	JORC Code explanation	Commentary
Mineral tenement and land tenure status	· Type, reference name/number, location and ownership including agreements or material issues with third parties such as joint ventures, partnerships, overriding royalties, native title interests, historical sites, wilderness or national park and environmental settings. · The security of the tenure held at the time of reporting along with any known impediments to obtaining a licence to operate in the area.	· GreenTech Metals Ltd, is the operating entity of a Joint Venture with Artemis Resources Ltd who holds E47/3719. · The tenement is in good standing with no known impediments.
Exploration done by other parties	· Acknowledgment and appraisal of exploration by other parties.	· The region has a long history of mining (Radio Hill) and exploration and has been explored for nickel and gold. Andover is currently the focus of a few companies following the success of Azure Minerals. · Prior to Greentech's involvement there has been limited work over the prospect, with historic exploration being restricted to airborne geophysics, ground geophysics and ground truthing by Legend Mining and Fox Resources · Historical exploration results and data quality have been considered during the planning of this drill program.
Geology	· Deposit type, geological setting and style of mineralisation.	· The Osborne prospect is interpreted to be located on the southern margin of the Andover Mafic intrusive Complex. · The prospect is overlain by strongly altered schistose and crystalline ultramafic intrusive rocks; probably mostly pyroxenites and peridotite. There is minor dolerite (?) and gabbro layers within this sequence.
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: o easting and northing of the drill hole collar o elevation or RL (Reduced Level - elevation above sea level in metres) of the drill hole collar o dip and azimuth of the hole o down hole length and interception depth o 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.	· Drill hole collar locations are shown in the maps and tables included in the body of the ASX release. · Two Reverse Circulation (RC) drill holes, the second with an added NQ diamond core tail of 199.5m have been completed during the current nickel exploration program for a total of 599.5 metres. The drill and sample programs were conducted in July 2022.
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 data aggregation methods were used.
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').	· No significant mineralisation was encountered. Drill holes were planned as perpendicular as possible to intersect the target EM plates so downhole lengths are usually interpreted to be near true width.
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 of drill hole collar locations and appropriate sectional views.	· Refer to figures and tables in the body of the ASX release.
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.	· No significant mineralisation was encountered
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.	· Ground Fixed Loop Electromagnetic survey data from 2007 has been used to assist targeting drillholes o  Loop Size: 550 x 500m o  Line Separation: 100m o  Station spacing 50m o  System: CRONE 3D PEM o  Current/Frequency: 20A, 5 Hz.
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.	· No further work is planned as the drill target is considered to have been adequately tested.
