OSBORNE LITHIUM JV INFILL ASSAYS RETURN 1.82% Li(2)O
KOBE LITHIUM TREND CONSISTENT OVER ~7.5km TOTAL LENGTH
HERITAGE SURVEY COMPLETED
DRILLING PLANNED FOR Q4 2023
Highlights:
· Further rock chip samples from Osborne JV (GRE:51%, ARV:49%) peak at
1.82% Li(2)O
· Kobe trend consistently returning high grade rock chips over 7.5km
length, ~ 1.5km within the Osborne JV tenement
· Total lithium bearing pegmatite trends in Osborne JV now ~5.5km of
strike length
· Osborne JV heritage survey completed, preparations for drilling
programs to commence in Q4
Artemis Resources Limited ('Artemis' or the 'Company') (ASX/AIM: ARV) is
pleased to provide an update on the lithium exploration program being
conducted at the Osborne Joint Venture (JV) tenement (GRE:51%, ARV:49%),
located within the Karratha region of Western Australia.
Executive Chairman Guy Robertson commented "Given the level of activity in the
region and the success of Azure Minerals Ltd project to the east of our
tenements, we are pleased with the continued success of the Osborne JV in
returning high levels of Li(2)O in the rock chip assays. We look forward to a
successful maiden drilling program being undertaken by our joint venture
partner Greentech Metals".

Kobe Trend - Rock Chips
Recent infill ground reconnaissance undertaken by the Company's JV partner
(Greentech Metals Ltd, ASX:GRE) on the Osborne tenement, has resulted in a
number of high grade rock chip results peaking at 1.82% Li(2)O (as per the
Greentech Metals, Ltd, ASX Announcement dated 30 October 2023) at the Kobe
trend. Multiple assays reported above 1% Li(2)O suggests that the Kobe trend
has the potential to be a consistent mineralised system over the length of
strike, including 1.5km of strike within the Osborne JV tenure. Significant
results include:
o 1.82% Li(2)O, 45ppm Ta(2)O5 and 80 ppm Nb(2)O(5) (sample 23GT20-509)
o 1.41% Li(2)O, 131ppm Ta(2)O5 and 74 ppm Nb(2)O(5) (sample 23GT20-531)
o 1.27% Li(2)O, 88ppm Ta(2)O5 and 76 ppm Nb(2)O(5) (sample 23GT20-505)

Drilling
A diamond drill rig will be mobilised to the Osborne JV location shortly to
commence drill testing of the pegmatites in the southern portion of the
tenement. The initial drill hole will be stratigraphic in nature and will take
advantage of previous heritage cleared drill sites for its location. The hole
is designed to investigate the mineralogy, lithium grade, dip and thickness as
well as other attributes of the southern pegmatite zone at depth. This
information will be used to refine the planned follow-on drill program which
will be focused on both Kobe and Osborne zones and may involve both RC and
diamond drilling.
Heritage Survey
The Ngarluma Aboriginal Corporation (NAC) has completed the initial heritage
surveys over selected portions of the Kobe and Southern pegmatite zones which
will allow RC and Diamond drilling to be undertaken in these areas. It is
anticipated that the heritage survey report will be made available during the
current quarter and in time to allow the follow-on drill program to get
underway. The initial clearances focused on areas with good strike continuity,
higher surface grades and wider pegmatite packages. Additional clearances are
planned.
This announcement was approved for release by the Board.

· The pegmatites are steeply dipping and up to 20m wide.
· The project area is underlain by the Archean Pilbara Craton,
specifically the West Pilbara Superterrane (WPST) of Hickman (2016). The
3280-3070 Ma WPST comprises numerous tectonostratigraphic packages (Sholl,
Regal and Karratha Terranes and the Whundo and Nickol River Basins) and
igneous complexes that have been variously affected by several tectonic
events. The easterly to east-north easterly trending Sholl Shear Zone (SSZ) is
a boundary for the regional rock packages. Metamorphic grade is higher to the
north of the SSZ, suggesting the present-day surface shows a slightly deeper
crustal level on the north side.
