Greater Carlow Project
Crosscut Copper-Gold Zone - Broad High-Grade Intercepts
Artemis Resources Limited is pleased to provide an update on activities at the
Crosscut Zone (Figure 2) at its 100%-owned Greater Carlow Project, located in
the Pilbara Region of Western Australia.
The Crosscut Zone has been interpreted to be a series of north-south striking,
high-grade repeating en echelon structures constrained by northwest striking
bounding structures. These northwest structures appear to be later in the
mineralising history of Carlow and may continue north and south, not
necessarily terminating against the Eastern Zone of the Carlow Main Lode
(Figures 2 and 3).
Highlights
· Major Copper-Gold Zone emerging at the Greater Carlow Project with
excellent first results from Crosscut Zone drilling campaign comprising 28
Reverse Circulation ("RC") drill holes for 5,494m and one diamond drill tail
for 135m.
· Diamond drill hole 22CCRD008 intersected massive sulphides, Figure 1,
returned:
· 16.6m @ 2.73% Cu, 1.19g/t Au, 0.049% Co from 255.8m

o Including 1.0m @ 2.70% Cu, 0.92g/t Au, 0.04% Co from 136m
· Drilling at Crosscut has now defined a significant, near-surface
mineralised system that Company geologists believe have the potential to
extend further to the north and south, significantly increasing the footprint
of the Carlow Area.
· Results for 7 drill holes at Crosscut and 5 at Carlow West are
pending. These additional holes will be released when assays are received.

Alastair Clayton, Executive Director commented: "The aim of this program was
to continue to test and follow trends of mineralisation and test the
structural model at Crosscut. The assays that have returned to date support
our geological observations, and we believe that the exploration team has
delivered what could be a game changing result for the future of the Greater
Carlow Project.
We very much look forward to reporting the 12 holes still pending and more
importantly adding our 2022 drill results to the upcoming Greater Carlow New
Resource Model."

A diamond hole was drilled in response to the high-grade intersection in
ARC344 which returned 22m @ 2.23g/t Au, 1.39% Cu, 0.457% Co from 247m. (ASX
Announcement 19(th) Nov 2021 "High-Grade Gold and Copper Intercepts from the
Carlow Crosscut Zone")
Best intersection in the diamond core was 16.6m @ 2.73% Cu, 1.19g/t Au, 0.049%

Mineralisation style encountered in hole 22CCRD008 is quartz-carbonate
breccias and veining with sporadic agglomerations of sulphides and massive
sulphide infills. This includes visible sulphides comprising of chalcopyrite,
pyrrhotite and pyrite.
Geometry of the mineralised lodes are shown in Figure 4 with core photos of
the mineralisation shown in Figure 5 and 6.

Figure 4: Section 9,960mE showing significant intersections for hole
22CCRD008. High grade intersections for ARC344 included for comparisons. Hole
ARC392 drilled updip from the massive sulphide occurrence hit mineralisation
ca110m above the massive sulphide intersection.
Structural information from the core suggests that the mineralisation does
strike N-S locally, with vein sets typically dipping steeply to near
vertically east. These are controlled by NW trending lineaments.
Mineralisation trend in the Crosscut zone seems to indicate that the plunge of
mineralisation is moderate to steep to the south.
Mineralisation can be seen at the end of hole (EOH) and drilling did not
proceed as the drillers had a lack of drill rods to continue. Mineralisation
at EOH in core can be seen in Figure 7.

Six holes to the north (ARC 363 to 365 and ARC395 to 397) were drilled based
on extending the mineralisation to the north from the high-grade intersections
encountered in holes ARC366 and ARC367 which returned grades of 8m @ 2.35% Cu,
5.01g/t Au, 0.400% Co from 80m and 8m @ 0.98% Cu, 0.96g/t Au, 0.020% Co from
167m, respectively as shown in Figure 8.
Holes ARC363, 364 and 365 encountered massive basalts and returned no
significant results.

Logging of holes ARC395, 396 and 367 showed that the NE holes encountered a
major fault zone and intersected pelites and black shales. Hole ARC395 showed
presence of sulphides associated with fuchsite with silicification and
sericite alteration as shown in Figure 9, 10 and 11. Assays for these holes
are pending. Please refer to Figure 3 for hole collar position.

Two additional holes, ARC387 and ARC389 drilled on section 9,920mN Loc (40m to
the south) had intersected mineralisation near the proposed pierce points.
These holes are shown in Figure 12 with RC chips with sulphides shown in
Figure 13.

An additional hole ARC403 had intersected sulphides consistent with those in
the high-grade zones to the south, meaning that the mineralised envelops had
'stepped' over to the west, in true en echelon form. Figure 14 shows the
sulphides that have been intersected in hole ARC403.
Refer to Figure 3 for drill collar location.

Figure 14: RC drill chips - Sulphide occurrence in ARC403 comprising pyrite
and pyrrhotite. Assays results are pending. Each chip compartment is 25mm
wide.
It appears that the Crosscut Zone is copper-rich, with zones of higher-grade
Au.
It is common for mineralised structures to anastomose downdip and they also
tend to stagger or step sideways within the confined margins of the NW zones.
There is now growing confidence in the interpretation, and it is now believed
that the mineralisation in Crosscut plunges moderate to steeply to the
southeast, towards Carlow East Main Zone.
Additional drilling required to extend the Crosscut Zone to the north.
Planning is in progress to determine the interaction with the Carlow East
Zone, located to the south of Crosscut.
Additional work at Crosscut
· Test the area to the north of the Crosscut Zone where the interpreted
structures trend as shown in Figure 15.
· Include surface mapping to trace out NW structures over the ridges
and the northern part of the tenement. Follow up with drilling.
· Chase out mineralisation to the south and the interaction between the
Crosscut Zones and Carlow East Main Zone.
· Test the new corridor to the west, which has been drilled and
required further follow up.
· Plan additional diamond drilling which can be used for metallurgical
test work.

Figure 15: Showing the location of the holes to test the mineralisation to the
north. ARC403 encountered sulphides but assays are pending. Interpretation of
the magnetics have identified similar NW structures to the west and NW along
strike. The area north of the cataclasite ridge is considered prospective for
mineralisation.
Recent drilling and exploration have identified several targets that require
follow up work including mapping and drilling. From the interpretations and
work completed to date, there is a high chance that Carlow will continue to
grow through further discoveries and creating shareholder value through
exploration success.
