SignIficant new LITHIUM pegmatite discoverY on 100% owned Artemis resources tenement
ROCK CHIP ASSAYS RETURN PEAK OF 1.82% Li2O
MINERALISATION CONFIRMED AS SPODUMENE
FURTHER EXPLORATION PROGRAMS UNDERWAY
_______________________________________________________________________________
Highlights:
· Ground reconnaissance sampling from 100% owned Artemis Resources tenement E47/1746 delivers positive assay results including:
o 23AR01-17 - 1.82% Li2O
o 23AR01-16 - 1.62% Li2O
o 23AR01-15 - 0.78% Li2O
· Mineralisation confirmed by XRD (x-ray diffraction) as being Spodumene
· Further reconnaissance and follow-up sampling to be undertaken across E47/1746
Artemis Resources Limited ('Artemis' or the 'Company') (ASX/AIM: ARV) is pleased to provide this update to shareholders on its recent ground reconnaissance program which has resulted in a significant lithium pegmatite discovery at the Mt Marie Lithium Prospect.
Executive Director George Ventouras commented "These rock chip results are a vote of confidence in the new technical team and the methodologies they've employed to explore for lithium bearing pegmatites on our 100% owned tenements. Importantly for the Company and the region, this discovery is further evidence of a potential corridor of lithium mineralisation extending beyond 40km in the west Pilbara region, where Artemis' tenements are located.
We are further encouraged by the geological structure of the pegmatites which appear to be coarse grained and feature large spodumene crystals and may parallel the Azure Minerals Andover discovery. We are excited by this development and looking forward to undertaking further work on our 100% owned tenement package".
Mt Marie Lithium Prospect
A small program of ground reconnaissance was undertaken towards the end of 2023 and targeted several key areas as identified by the new technical team. Our ground team was deployed and through the use of new on-ground techniques, the team was able to target and test various pegmatites.
Figure 1. Artemis Resources West Pilbara tenements
In total, 24 new target areas in the northern and central sector of tenement E47/1746 have been identified and the Company will continue to systematically explore these to determine which are host to lithium bearing pegmatites.
Figure 2 Mt Marie Lithium Prospect
Aerial surveying via the use of drones has commenced to fully map these areas and to assist with follow up sampling plans and will be completed shortly. Following this, further rock chip sampling will be undertaken across the tenement.
Figure 3. Pegmatite outcrop at Mt Marie Lithium Prospect
The initial rock chip assays have delivered encouraging results and include the following;
· 23AR01-17 - 1.82% Li2O
· 23AR01-16 - 1.62% Li2O
· 23AR01-15 - 0.78% Li2O
· 23AR01-21 - 0.65% Li2O
· 23AR01-22 - 0.50% Li2O
Two of the rock chip samples were tested for mineralogy type at Curtin University. This analysis has confirmed that the host mineral for the lithium is spodumene. The spodumene crystals are large (figure 5) and do not exhibit deformity to the extent of other nearby discoveries. These samples and their subsequent structure would appear to parallel the geological fingerprint of the pegmatites at the Andover project of Azure Minerals where they have reported an exploration target of 100-240mt @ 1.00-1.5% Li2O1. Azure Minerals is currently subject to a takeover proposal via a joint bid with SQM and Hancock Prospecting2.
The lithium bearing pegmatite at the Mt Marie prospect occurs along a mirrored or similar NE structural trend to pegmatites discovered by Azure Minerals some 20km to the east.

There is no reported previous exploration for lithium bearing pegmatites on the tenements. · No other exploration companies generated data was used in this release. · Regional RTP aeromagnetics and geology from Geological Survey of WA. · The area was previously explored by Fox Resources Ltd and was focussed on nickel and gold exploration. |
Geology | · Deposit type, geological setting and style of mineralisation. | · The lithium bearing pegmatite zone trends NE-SW and is hosted in proximity to the contact between the Regal and the Clearville Formations. · The lithium pegmatites appear as coarse crystalline with primary feldspar quartz composition. Further mapping is being undertaken to understand the surface characteristics. |
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. | · Not applicable as no drilling has been undertaken |
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. | · Not applicable |
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'). | · Not applicable as surface sampling is reconnaissance in nature. |
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. | · All the appropriate maps are provided in the body of this announcement. |
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. | · This announcement discusses the findings of recent reconnaissance sampling and associated assays. |
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 the meaningful exploration data has been included in the body of this announcement.
|
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. | · Artemis Resources plans to conduct further ground reconnaissance and sampling in the short term to determine the surface extent both laterally and along strike and also the economic potential of the prospect.
