Diamond drilling scheduled for spring season of 2024 after

(Aboriginal Heritage Impact Permit) as well as the rainy
winter season.

Plans include drilling two or three deeper angled diamond
drill holes beneath RC drill holes completed by Catalina in
2022
➢ RC drilling intersected multiple stacked gold (“Au”)
and silver (“Ag”) lenses at Rock Lodge. The
deepest hole, SRLRC05 intersected 4 separate
mineralised zones from 75m to 99m downhole
(including 2m @ 2.13 g/t Au and another 2m @
2.12 g/t Au).
➢ At the end of SRLRC05 at 102m, the rocks were
still showing signs of pervasive hydrothermal
alteration. This hole suggests multiple mineralized
zones are to be expected in future drilling
programs.
➢ West of SRLRC05, Catalina’s drilling intersected
mineralisation in SRLRC02 (8m @ 1.08 g/t Au
including 3m @ 2.12 g/t Au).
➢ Intersections from Catalina’s SRLRC02 to
SRLRC05 in conjunction with the historical drilling
(including MYRC01) constitute a very wide (60m)
mineralised envelope.

Catalina Resources (“Catalina” or “the Company”) is pleased to
announce scheduling of diamond drilling at the Rock Lodge Project
in the spring of 2024. The Company has received the necessary
approvals from the NSW Resource Regulator for the planned
exploration.

Catalina advises that the NSW Resources Regulator (Regulator) has revoked the
Suspension Notice issued in mid-2022, in relation EL 9155 as the Company has complied
with the stipulated considerations in engaging third-party consultants to review its systems
and processes and to complete an ecological review; reporting to the Regulator on the
outcomes of the reviews and it’s intended response; and in obtaining an AHIP.
The Regulator has further advised that it is satisfied that the terms of the Enforceable
Undertaking in this connection have been completed.
In addition, Catalina has applied for and been granted a new Assessable Prospecting
Operation Application (APO 001743), replacing the previous Activity Approval which will
ensure the findings and recommendations from the reviews and the AHIP are taken into
consideration in conducting any future works on EL 9155.
The Company has also agreed to a settlement to its indemnity claim on the contractor
involved with the alleged breaches in this regard.
Next Steps
Catalina has engaged a consultant archaeologist to arrange the salvage and relocation of
the artifacts in accordance with the AHIP which is expected to be done over coming weeks.
Following the completion of these works and after the rainy winter season, Catalina plans
to drill two or three deeper angled diamond drill holes beneath previously drilled RC holes
in the spring of 2024. Additionally, diamond drilling will enable the collection of orientated
structural data, including dips and strikes of mineralised veins, necessary for future drill hole
planning and calculations of the true widths of mineralisation. Planning for one of these
diamond holes is illustrated in Figure 1.
Down Hole Electro Magnetic (DHEM) surveys may also be employed, searching for off-hole
conductors, which may represent wider massive sulphide mineralisation than what has
already been found in the RC drilling.

proposed diamond hole. It illustrates the wide zone (approx. 60m) of polymetallic
mineralisation intersected in all drilling, from SRLRC02 to MYRC001.
Background
The Rock Lodge Project exhibits high-grade polymetallic mineralisation associated with
structurally controlled epigenetic massive sulphide veins, Figure 1 and 2. Diamond holes
drilled in 1985 intersected up to 8m of massive sulphide with recorded grades up to 4.28g/t
Au, 35g/t Ag, 0.79% Cu and 13.5% zinc. Diamond hole SGDH08 intersected 12m @ 1.2 g/t
Au, 9.8 g/t Ag and 0.2% Cu. The mineralisation is associated with massive and
disseminated pyrite‐arsenopyrite‐chalcopyrite‐sphalerite sulphides and quartz, within host
phyllites and sandstone. This is exposed on the surface as a distinct gossan and ironstone.

The grades intercepted during historical drilling show the area to be highly mineralised and
the mineral assemblages are synonymous with other major mineral deposits within the
Canberra to Cooma region of the Ordovician Lachlan Fold Belt.
Areas of old workings coincide with an IP chargeability anomaly caused by the pyrite
alteration halo. Rock chip samples of gossanous material and quartz veins collected by
Shree returned a best result of 7.3g/t Au with 6,049ppm As and 446ppm Bi. RC drilling
tested those extensive and continuous IP anomalies that are also coincident with very
anomalous soil and rock chip geochemistry.

RC drilling campaign by the Company completed in April 2022 at the Rock Lodge prospect
in the Lachlan Fold Belt Project, NSW intersected significant mineralisation. The Rock
Lodge Project (EL 9155) covers an area of 163 km² and is located 35 km south of Cooma.
It is prospective for orogenic, Intrusion Related Gold Systems (IRGS) and skarn related gold
mineralisation.
RC drilling completed in April 2022 tested prioritised drill targets consisting of extensive and
continuous IP anomalies that are coincident with very anomalous soil and rock chip
geochemistry.
Catalina’s drilling intersected a wide zone of stacked vertical lenses of polymetallic
mineralisation at Rock Lodge. For example, RC hole SRLRC05 intersected four (4)
significant mineralised zones over a width of 24m, from 75m to 99m (including 2m @
2.13 g/t Au and another 2m @ 2.12 g/t Au), illustrated in Table 1. At the end of hole at
102m, rocks were still pervasively hydrothermally altered (pyrite, silica, sericite) suggesting
that additional downhole zones may have been intersected if excessive water flows had not
stopped drilling. West of SRLRC05, Catalina’s drilling has intersected mineralisation in
SRLRC02 (8m @ 1.08 g/t Au including 3m @ 2.12 g/t Au).
As suggested by the range in elements present, the mineralisation signature suggest a high
temperature fluid may have been responsible. Apart from Au and Ag, the mineralisation
includes varying amounts of Bi, As, Cu, Sb, Pb, Cd and Zn. Table 1 tabulates the significant
intersections received from Catalina’s RC drilling.

The intersections from Catalina’s drill holes SRLRC02 to SRLRC05 and also the historical
drilling, including MYRC01, constitute a very wide (60m) mineralised envelope of stacked
vertical lenses of significant polymetallic sulphide at Rock Lodge. Two hundred meters to
the north, IP anomalies and similar anomalous rock chip geochemical signatures (Figure
3), suggest the mineralisation envelope may be continuous at least to this area. As the
envelope is open in all directions further drilling focusing on the continuity, depth and lateral
extent of the stacked veins represents a high priority drill target for Catalina Resources.

IRGS Models.
The gold, bismuth and copper mineralisation at Rock Lodge is interpreted to have an affinity
with the Intrusion Related Gold System (IRGS) style of mineralisation. There is potential at
depth for bulk tonnage gold mineralisation associated with an intrusion. Characteristic
features of IRGS mineralisation include sheeted veins containing gold with elevated
bismuth, arsenic, silver, copper, lead, zinc and tin. The systems are commonly
geochemically zoned around a central intrusion. They can also have elevated sulphide

which can be detected with induced polarisation (resistivity lows). Many of these features
are present at Rock Lodge.
The multiple veins at Rock Lodge may represent the upper zone of a mineralised system
above an intrusion at depth, with bulk tonnage potential (Figure 4). Planned drilling will
initially target the shallow veins but pending results deeper drilling is planned to test for an
interpreted source intrusion at depth. Several Silurian and Devonian aged intrusions have
been mapped in the Rock Lodge area by the NSW Geological Survey.
