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

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.
