Lithium Bearing Pegmatites Identified at West Pilbara Joint Venture Project
Highlights:
· Lithium bearing pegmatites identified within Osborne Joint Venture (Artemis 49% interest).
· Significant assays:
o 1.8% Li2O from Sample No 23GT11-041
o 1.7% Li2O from Sample No 23GT11-042
o 1.58% Li2O from Sample No 23GT11-039
· Mineralised trend identified extends within JV tenure.
· Field activities are currently underway in the search for lithium bearing pegmatites and dykes on Artemis tenements.
· Artemis tenements E47/1746 and E47/1797 adjoins the JV project.
· Review of the company's historic geochemical soils sampling data indicates elevated lithium and lithium pathfinder elements within the company's 100% held tenure.
Artemis Resources Limited is pleased to advise that lithium pegmatites have been identified on the Osborne Joint Venture (Greentech Metals Ltd 51% / Artemis Resources 49%).
As announced by GreenTech Metals Limited (ASX: GRE) in the ASX release of 7 July 2023[1] , GreenTech announced that the Kobe Lithium Prospect extends into the Joint Venture exploration licence E47/3719. The mineralised trend defined to date within JV tenure is shown in Figure 1 below. High tenor lithium assays received within the project area include:
· 1.8% Li2O from Sample No 23GT11-041
· 1.7% Li2O from Sample No 23GT11-042
· 1.58% Li2O from Sample No 23GT11-039
Further work is planned on the Joint Venture tenement with sampling and mapping aimed at identifying the full extent of the mineralised pegmatite zone and the consistency of the lithium minerology and grade. Preparations have commenced to enable a maiden drilling program as soon as all approvals are received.

Artemis West Pilbara exploration
As part of the Company's West Pilbara exploration review and field work, Artemis has also commenced a review and assessment of lithium prospectivity in its 100% owned tenure. Artemis currently controls approximately 144 km2 in the West Pilbara adjacent to the lithium find.
Artemis has commenced a review of its extensive soils database and commissioned a third-party consultant to process detailed satellite spectral data.
A review of the company's historic regional exploration soils database indicates elevated lithium and lithium pathfinder elements on Artemis tenements E47/1746 and E47/1797.
The soils data is comprised of three different analytical methods being conventional Aqua Regia, Ionic Leach and Ultrafine Fraction (UFF) collected between 2018 and 2023. A total of 4,534 samples were reviewed (Figure 2) and levelled against each other using percentile comparison against each data set and then plotting the +95th percentile of each to develop Lithium and pathway element trends (Figures 3 and 4).
Figure 2: Geochemical data sets used for Lithium prospectivity review.
Figure 3: Plot of levelled +95th percentile Lithium soils data with circled anomalous trends
Figure 4: Plot of 95th Percentile Rubidium soils data with circled anomalous trends
The data has defined seven distinct lithium cluster anomalies within E47/1797 and E47/1746 with elevated Lithium above the 95th percentile. Two of these anomalies also correspond with two broad rubidium anomalies and will form part of the initial reconnaissance programs in identifying potential lithium bearing pegmatites.
First pass field reconnaissance programmes have commenced investigating the source of the lithium soil anomalies with rock chip samples collected for lithium analysis. Results from the initial rock chip samples are expected in August.
Artemis holds a 9.67% interest in GreenTech Metals Limited (ASX: GRE).

· 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. |
· The soil samples were taken on north-south orientated lines spaced 160 m apart with individual samples taken on a nominal 80 m sample spacing along the lines. |
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. |
· Surface soil sampling on a grid basis. The grid was designed to sample across the interpreted zones at a high angle. |
Sample security |
· The measures taken to ensure sample security. |
· Chain of Custody for soil samples is maintained by Artemis personnel and contractors. Soil samples were collected and stored in seal top polyethylene sample bags which were then stored in numbered storage boxes. These boxes were then transported by Artemis personnel to Bishops Transport in Karratha, who subsequently transported the samples to LabWest in Perth, Wester Australia. Sample submission documents listing the batch number and sample number series accompany the samples at each stage. Samples are checked by LabWest to confirm receipt of all samples and check the condition of the sample Batch. |
Audits or reviews |
· The results of any audits or reviews of sampling techniques and data. |
· No Audits have been completed. |
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. |
· The Greater Carlow Project is in Exploration Licence E47/1797, held by KML No2, a 100% owned subsidiary of Artemis Resources. · E47/1797 is within the Ngarluma Native Title Determination Area. The tenure is subject to an agreement allowing mining activities including exploration. · There are no historical cultural sites or environment protected areas that would prevent the Company from exploring the licence. |
Exploration done by other parties |
· Acknowledgment and appraisal of exploration by other parties. |
· The most significant work to have been completed historically in the Greater Carlow area was completed by Open Pit Mining Limited between 1985 and 1987, and subsequently Legend Mining NL between 1995 and 2008. · Work completed by Open Pit consisted of geological mapping, geophysical surveying (IP), and RC drilling and sampling. · Work completed by Legend Mining Ltd consisted of geological mapping and further RC drilling. · Legend also completed an airborne ATEM survey over the project area, with follow up ground-based FLTEM surveying. Re-processing of this data was completed by Artemis and was critical in developing drill targets for the completed RC drilling. · Compilation and assessment of historic drilling and mapping data completed by both Open Pit and Legend has indicated that this data is compares well with data collected to date by Artemis. Validation and compilation of historic data is ongoing. · All exploration and analysis techniques conducted by both Open Pit and Legend are considered to have been appropriate for the style of deposit. |
Geology |
· Deposit type, geological setting and style of mineralisation. |
· Gold mineralisation is associated with shears and breccias associated with the Regal Thrust within greenstones sequences of the Roebourne and Regal Complexes. · The greenstone package includes mafic to ultramafic volcanic rocks along with sedimentary units including chert. · The greenstones are intruded by the Andover Intrusive Complex, consisting of a series of gabbro and pyroxenite intrusions. · Sulphide mineralisation consisting of chalcopyrite, cobaltite, pyrrhotite, pentlandite and pyrite appear to localise in varying quantities near some of these intrusions, particularly when associated with an earlier shear or splay associated with the Regal Thrust. |
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. |
· No drilling undertaken as part of this program. |
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 or intercept calculations are included in this release. |
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 drilling undertaken as part of this program. |
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. |
· Representative plans are provided in this 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 report is considered balanced and provided in context. · Further exploration including geophysical surveys, mapping, sampling, and other exploration activities are required to fully understand the results in greater detail. |
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. |
· Historical data collected by Artemis Resources was used to choose the sites for the Ultrafine soils program. · Europa Gravity and Marillion EM targets announced 14 November 2022. · Titan identified as potential gold exploration target from 2018 ionic soils program announced 5 November 2018. |
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. |
· The Company plans to complete mapping, geochemical sampling including rock and Ultrafine soil sampling and geophysical surveys to further investigate the potential for the Greater Carlow project to host additional mineralisation including gold, copper, cobalt, and nickel. |
