As requested by the ASX, Artemis Resources Limited ('Artemis' or
the 'Company') (ASX/AIM: ARV) wishes to provide a revision to the
above announcement, as originally released on 29 November 2023.
The addendum to the release is to provide further information
contained within the JORC table with particular reference to the
diamond drilling sampling and collection methodology. The revised
JORC table below provides a more detailed analysis of sampling and
drilling techniques, sample preparation and logging.
This announcement has been approved for release by the
Board.

About Artemis Resources
Artemis Resources (ASX/AIM: ARV; FRA: ATY; US: ARTTF) Artemis
Resources Limited is a gold, copper and lithium focused resources
company with three major projects in Western Australia; the Greater
Carlow Castle gold-copper-cobalt project in the West Pilbara; the
Paterson Central project in the Paterson Province (located adjacent
to Greatland Gold / Newcrest's recent gold-copper discovery at
Havieron; and the Osborne JV (Artemis 49%; GreenTech Metals
(ASX:GRE) 51%) in the West Pilbara.
Artemis also owns the Radio Hill processing plant, the only
processing plant in the West Pilbara region, 35km from
Karratha.

have been variously affected by several tectonic
events. The easterly to east-north easterly trending
