Further High-Grade Intercepts Determined
HIGHLIGHTS
· Drilling results from current drilling program highlight high-grade
intercepts of 113.1 m @ 1.32% Cu and 0.41 g/t Au from 8.1 m, including 54.6 m
@ 1.84% Cu and 0.74 g/t Au from 60.4 m.
· Conditional approval issued by the National Water Resources Board on
water abstraction in preparation for MCB Project's operational requirements.
· Feasibility Update study and FEED Program on schedule.
_______________________________________________________________________________
Celsius Resources Limited ("Celsius" or the "Company") (ASX, AIM: CLA) and its
Philippines affiliate company Makilala Mining Company, Inc. ("MMCI") is
pleased to announce results from the drilling program which commenced in June
this year 1 . The drilling program is focused on geo-technical and
hydro-geological drilling and additional metallurgical test work. Results from
the metallurgical testwork drilling has intercepted further high-grade
mineralisation where predicted, including some further extensions to the
previously interpreted high grade mineralisation.
The detailed assay results are shown in the tables below, and as stated by
Peter Hume, our Country Technical Director, "This recent drill hole was
completed to provide Ausenco and its mineral processing team with sufficient
high-quality material from the MCB deposit so that further testwork can be
completed to reaffirm the process plant design. With these new higher-grade
intercepts, we have further confidence that our mine plan, development and
operating strategy will deliver the best value for the Project, our investors,
shareholders and the community".
The Philippines National Water Resources Board has issued a Conditional Water
Permit for the next twelve months, which covers the start of our construction
of the Maalinao-Caigutan-Biyog Copper-Gold Project ("MCB Project").
The feasibility study update continues on schedule and the Company recently
received the interim study report from Ausenco 2 . The report confirmed the
work that has been progressed since June, which pointed to enhancements in the
site layout, underground mine design, process plant design and materials
handling, which are likely to result in improved operating costs and an
overall improvement in project economics. When combined with updated commodity
price forecasts, the feasibility study financial model is expected to show an
overall improvement in the project's valuation. When the studies have been
completed, an updated JORC Mineral Resource Estimate, Mining Reserve statement
and Feasibility Study can be published. In parallel, the Front-End Engineering
Design ("FEED") study is advancing detailed engineering, ESG initiatives,
sustainability, environmental stewardship, and social responsibility to
support lasting value and meet to stakeholder expectations. The current scope
of work is expected to be completed in December.

Drilling Results
The recently completed metallurgical test hole returned results that were
higher than anticipated when compared to the resource model, confirming the
presence of consistent high-grade copper mineralisation. The hole intersected
a continuous interval of 113.1 metres from 8.1 metres downhole, grading 1.32%
Cu and 0.41 g/t Au, including a higher-grade zone of 54.6 metres from 60.4
metres grading 1.84% Cu and 0.74 g/t Au. These results provide strong support
for the robustness of mineralisation within the targeted zone and will be
incorporated into future metallurgical test work and resource evaluation.

As noted in the Company's ASX/AIM announcement of 7 August 2025, Celsius and
MMCI continue active discussions with a number of parties with regards to
potential financing for the MCB Copper-Gold project.
Maharlika Investment Corporation ("MIC") have provided initial financing from
the First OLSA bridging loan and continues to express investment interest in
in the MCB project 4 . Discussions with all interested investment parties,
including MIC and Kiri Industries Limited are continuing, although there is no
guarantee that discussions will lead to any definitive agreement 5 .
The Company is focused on completion of the updated Feasibility Study and FEED
program whilst securing the best possible financing solution for MCB project
and the best possible value for Celsius shareholders. We continue to deliver
on our commitments to The Philippines Government and our highly supportive
Balatoc community, with whom we are confidently advancing the MCB project.
Ancillary Permitting Update
The Philippine National Water Resources Board ("NWRB") 6 has issued a
Conditional Water Permit authorising MMCI to commence water use activities in
support of the MCB Project's development, subject to compliance with specific
conditions. In accordance with the Water Code of the Philippines (PD 1067) and
its Implementing Rules and Regulations, MMCI is required to install measuring
devices and submit quarterly utilisation reports to the NWRB. These reports
enable the NWRB to verify actual water withdrawals, assess the sustainability
of the source, and ensure that project water use does not impair existing
rights or deprive surrounding communities of their water needs. The issuance
of a permanent water permit is contingent on satisfactory compliance with
these monitoring and reporting requirements.
The Company remains committed to working diligently to meeting all regulatory
requirements while safeguarding local water resources to secure full permit
conversion.
MCB COPPER-GOLD PROJECT
The MCB Copper-Gold Project (MCB) is located in the Cordillera Administrative
Region in the Philippines, approximately 320km north of Manila (Figure 1). It
is the flagship project within the Makilala portfolio which also contains
other key prospects in the pipeline for permit renewal/extension.
An updated JORC compliant Mineral Resource Estimate was announced for the MCB
Project on 12 December 2022, comprising 338 million tonnes @ 0.47% copper and
0.12 g/t gold, for a total of 1.6 million tonnes of contained copper and 1.3
million ounces of gold, of which 249 million tonnes @ 0.44% copper and 0.11
g/t gold is classified as Indicated, 42 million tonnes @ 0.52% copper and 0.11
g/t gold is classified as Inferred, and 47 million tonnes @ 0.59% copper and
0.19 g/t gold is classified as Measured.
A Study for the MCB Project was announced by CLA on 1 December 2021, which
identified the potential for the development of a copper-gold operation with a
25-year mine life. The Study was based on an underground mining operation and
processing facility to produce a saleable copper-gold concentrate.
Highlights from that Study include a Post tax NPV (8%) of US$464m and IRR of
31%, assuming a copper price of US$4.00/lb and gold price of US$1,695/oz.
Initial capital expenditure is estimated to be US$253m with a payback period
of approximately 2.7 years. The designed mine production is matched to a
2.28Mtpa processing plant which will treat ore with an estimated average grade
of 1.14% copper and 0.54g/t gold for the first 10 years of planned production
with a C1 7 cash costs at just US$0.73/lb copper, net of gold credits.
Please note that as at the date of this announcement there are studies ongoing
to update the Feasibility Study for the Project and to complete the Front-end
Engineering and Design. These studies are scheduled for completion before
December 2025 8 .

· The relative quality and detail associated with the drilling information is
considered to be of a high standard. This has enabled the author to
establish a high level of confidence associated with the historical drilling
information.
Geology · Deposit type, geological setting and style of mineralisation. · The geological setting for the MCB copper-gold mineralisation is typical
of a porphyry copper + gold + moly deposit as commonly defined in many
academic papers (Hedenquist and Lowernstern, 1994; Sillitoe, R. H., 2010.
Corbett and Leach, 1997). The mineralisation and associated alteration exist
across the contact between the genetically related intrusive body (tonalite)
and the surrounding host rock material. In most cases the surrounding host
rock is a mafic volcanic, however, in some instances the older (not
genetically related to copper-gold mineralisation) intrusive bodies also exist
in contact with the younger intrusive resulting in broad sections of
mineralisation and alteration within a series of intrusive bodies.
· There is also evidence at MCB for epithermal vein deposit types which
exist within close proximity to the large-scale porphyry copper-gold
mineralisation. At this stage only the deposit type that is identified from
the drilling information for MCB is a porphyry copper-gold style.
· Basalt lava flows make up the majority of the host rocks in the tenement
area, which is part of the oldest exposed unit, Basement Complex. This
Cretaceous-Paleogene Metavolcanics has been intruded by quartz diorite
complex, which in Kalinga, ranges in composition from gabbro to tonalite.
· A later stage Tonalite intrusion exists throughout the project area and
is interpreted to be genetically related to the copper-gold mineralisation at
MCB deposit.
· A dacite flow and dacitic pyroclastic blankets the older basalt host rock
and tonalitic intrusive rocks.
· There are four types of ore mineralisation that were emphasized in the
project:
o Type 1 - Early high-grade porphyry Cu-Au mineralisation, hosted both in
tonalite and basalt.
o Type 2 - Mix of high-grade porphyry Cu-Au (Type 1) and high-sulphidation
mineralisation (Type 4). Hosted in basalt and tonalites, but with strong Type
1 mineralisation that was partially overprinted by ore Type 4.
o Type 3 - Medium grade porphyry-copper
o Type 4 - High-sulphidation epithermal mineralisation
