Celsius Resources Limited ("Celsius" or the "Company") (ASX, AIM: CLA) is pleased to provide the following summary of the Company's activities for the quarter ended 30 September 2025.

Projects

Maalinao-Caigutan-Biyog Copper-Gold Project ("MCB Project" OR THE "PROJECT"), Philippines

Makilala Mining Company, Inc. ("MMCI"), the Celsius Resources affiliate company in the Philippines, is actively progressing the FEED and updating the MCB Project's Feasibility Study to advance early development works[1].

The FEED program remains on track, with the current scope of work progressing steadily towards its targeted completion in December. Parallel to this, the Feasibility Study update is being actively informed by ongoing field work at the Project site, ensuring that the latest site investigations are integrated into the evolving development strategy. Ausenco has issued an Interim Study Report to the Company which outlined key enhancements in several technical areas. Notable improvements were identified in the site layout, underground mine design, process plant configuration, and materials handling systems. These refinements are expected to yield more efficient operating costs and contribute to a stronger overall economic profile for the Project. Updated commodity forecasts are also anticipated to positively impact the financial model.

In parallel, the Geotechnical and Hydrogeological Drilling campaign is well advanced towards producing a comprehensive surface and subsurface data and model that will enhance the underground mine plan, refine the process plant layout, and improve surface infrastructure design. The results will play a critical role in guiding updates to the Feasibility Study.

During the quarter, one hole from the current drilling program was a metallurgical test hole that delivered better-than-expected results compared to the resource model, confirming consistent high-grade copper mineralisation. Significant assay results contain 113.1m @ 1.32% Cu and 0.41g/t Au from 8.1m, including 54.6m @ 1.84% Cu and 0.74m g/t Au from 60.4m. These findings reconfirmed the mineralisation of the target zone and will inform upcoming test work and resource assessment.[2]

These results reinforce the expectation that the Project will deliver optimal value to stakeholders, including investors, shareholders, and the community.

SOCIAL DEVELOPMENT

As part of the Company's commitment under the Social Development and Management Program ("SDMP"), several key initiatives were also implemented to build the capacities of the host community and support community development:

Stakeholder Engagement

Monthly meetings of the joint Barangay Balatoc-Council of Elders were consistently facilitated, serving as a vital platform for presenting technical, environmental and social updates and addressing project-related concerns. These gatherings fostered transparency, open communication, and a stronger sense of partnership between the Company and the community.

Community-Based Skills Training

A total of 130 host community members completed various skills training implemented by the Company in partnership with the Technical Education and Skills Development Authority ("TESDA") and local service providers. These training courses were designed to equip participants with practical, in-demand competencies that enhance employability, strengthen livelihood opportunities and promote financial self-reliance within the community. The programs covered a range of technical and vocational disciplines aligned with local economic opportunities, enabling training graduates to pursue jobs, start small businesses, or contribute to ongoing infrastructure projects[4]. The financial literacy and management trainings will help participants effectively manage income, savings and small enterprises.

As part of the practical application component, trainees contributed to actual construction and maintenance tasks, including electrical-related masonry work at local schools and churches. These outputs served dual purposes: reinforcing the trainees' learning through real-world practice and directly improving community facilities. The initiative reflects a strategic approach to workforce development, empowering individuals with marketable skills while simultaneously addressing local development priorities.

Educational Assistance and Scholarship

Educational assistance and scholarship was extended to a total of 254 beneficiaries from Barangay Balatoc, reflecting a strong commitment to uplifting the community through access to higher education and professional advancement. Of these, 202 were college students pursuing undergraduate degrees across various fields, while 30 were enrolled in graduate school programs, furthering their academic specialisation and research capabilities. Additionally, 22 beneficiaries received support for their licensure examination review where three reviewees passed their licensure exams in Medical Technology, Criminology, and Social Work-marking a significant milestone in their professional journeys and contributing to the pool of qualified practitioners in the region.

Furthermore, full scholarships were awarded to two students pursuing degrees in Mining Engineering. This targeted support not only eases the financial burden of their studies but also aligns with the strategic goal of developing local expertise in the mining sector. By investing in future professionals, the program helps ensure that the community can actively participate in and benefit from industry-related opportunities.

ENVIRONMENTAL MANAGEMENT

Several key plans and program documents were developed and submitted to the national government in line with the MCB Project's Environmental Compliance Certificate ("ECC"). These include the Information, Education, and Communications Plan, Hazardous Chemicals Management Plan, Carbon Sink Program, and the Biodiversity Management Plan.

Also, a comprehensive internal gap assessment was carried to strengthen the Company's Environmental Management System  ensuring readiness for ISO 14001 certification. A series of employee awareness sessions on Environmental Management Systems were actively sustained. These sessions focused on harmonising procedures across teams, fostering a culture of environmental responsibility and reinforcing consistent, effective practices throughout the organisation.

ANCILLARY PERMITS

Water Permit

The Philippine National Water Resources Board ("NWRB") has granted a conditional water permit, authorising the initiation of water usage activities-an essential step in preparing for the project's operational requirements. This approval is subject to strict adherence to the conditions stipulated under the Water Code of the Philippines[5].

As part of its compliance obligations, MMCI is required to install calibrated water measuring devices and submit quarterly utilisation reports to the NWRB. These reports serve as a basis for the NWRB to validate actual water withdrawals, evaluate the long-term sustainability of the water source, and ensure that project-related water use does not infringe upon existing water rights or compromise the needs of surrounding communities. The transition from a conditional to a permanent water permit will depend on MMCI's continued and satisfactory compliance with these monitoring and reporting requirements.

Tree-Cutting Permit

Preparatory activities are currently in progress to fulfill the documentary requirements for the Tree Cutting Permit application.  This permit is an essential regulatory step for initiating site development. This process is being carried out along the finalisation of the optimised mine design and layout, which will identify specific zones where tree removal may be necessary to accommodate project infrastructure.

Construction Permit

A draft Memorandum of Agreement and Implementation Plan has been developed, aimed at streamlining the construction permitting process in line with the Project schedule. Forthcoming consultations with the Local Government Unit of Pasil will help refine the provisions of the agreement and facilitate its formalisation.

FUNDING SUPPORT

To support these ongoing activities, the Company has made a third drawdown of funds from the Maharlika Investment Corporation's ("MIC") First OLSA bridging loan. As at the date of this report, MMCI had drawn US$6 million of the US$10 million First OLSA to fund MMCI MCB Project related activities[6].

Celsius and MMCI have been actively engaging with investors to explore funding options for the MCB Project. MIC has continued to express interest in participating through an equity investment in the MCB Project. A non-binding Memorandum of Undertaking was signed with Kiri Industries, signaling potential investment collaboration. Discussions with prospective investors remain ongoing, with a focus on structuring both debt and equity financing solutions. The Company is confident that a comprehensive financing package for the Project can be achieved in the next quarter.

BOTILAO COPPER-GOLD PROSPECT

MMCI has formally submitted its Exploration, Environmental, and Community Development Programs as part of the requirements for the first renewal of its exploration permit. The Exploration Work Program outlines planned geological activities and resource evaluation strategies, while the Environmental Program details mitigation measures during exploration activities including monitoring protocols, and compliance with national environmental regulations. The Community Development Program highlights initiatives aimed at assisting the host community with its community development needs and strengthen community relations.

The renewal of the exploration permit is ongoing and MMCI expects that the first renewal will be finalised by December 2025. Expenditure on this project is being carefully managed to focus on essential activities that sustain meaningful engagement with the community, local government units, and regulatory agencies, thereby maintaining project momentum and stakeholder confidence as the Company prioritizes the MCB Project.

Opuwo Cobalt Project, Namibia

As disclosed previously to the market, the Company has opened its data room to parties interested in acquiring the Company's Opuwo Cobalt project in Namibia ("Opuwo"). Several parties have expressed interest in acquiring the Project and are continuing with their due diligence. As of the date of this report, no binding agreement has been reached and, although discussions are continuing, there can be no certainty that any binding agreement will be reached or the timing of any such agreement.

The Opuwo tenement permit EL4346 is due for renewal. The Company has lodged the necessary documentation to have the permit renewed with the Ministry of Mines. The tenement remains active until such time that it is renewed by the Ministry of Mines and the Company is continuing discussions on the renewal process with the Namibian authorities.

SAGAY Copper-Gold Project, Philippines

Tambuli Mining Company, Inc. ("TMCI"), a wholly owned Philippine subsidiary of Celsius in the Negros Islands, is actively engaging with the Department of Environment and Natural Resources-Environmental Management Bureau on the evaluation and approval of its Environmental Impact Statement ("EIS") for the Sagay Copper-Gold Project ("Sagay Project").

The EIS serves as the foundation for securing an Environmental Compliance Certificate ("ECC"), as mandated by the Philippine Mining Act of 1995[7]. This certification ensures that the development plans and engineering designs submitted under the Declaration of Mining Project Feasibility ("DMPF") are technically viable, environmentally responsible, and socially acceptable. Expenditure on the Sagay Project is being carefully managed to focus on essential activities that sustain meaningful engagement with the community, local government units, and regulatory agencies, thereby maintaining project momentum and stakeholder confidence as the Company prioritizes activities at the MCB Project.
