It is a preliminary technical and economic study based on low-level technical and economic assessments that are not sufficient to support the estimation of Ore Reserves or to provide assurance of an economic development case at this stage. Further exploration, evaluation, engineering, metallurgical, environmental, permitting, approvals, funding, offtake and commercial work is required before Critica will be in a position to assess whether it is possible to estimate any Ore Reserves or assess whether Critica may be able to provide any assurance of an economic development case. The Company has concluded that it has a reasonable basis for disclosing the production target and forecast financial information, based on the material assumptions, modifying factors and technical information summarised in its ASX announcement dated 29 September 2026. However, there is no certainty that the assumptions will be correct or that the outcomes indicated by the Scoping Study will be achieved. Investors should not make investment decisions based solely on the results of the Scoping Study. Production target and Mineral Resources No Ore Reserve has been declared for the Mt Lindsay Project. The Scoping Study production target is based solely on part of the Main and No.2 deposits within the updated JORC 2012 Mineral Resource Estimate (refer ASX Announcement “Critica Updates Mt Lindsay Tin-Tungsten Mineral Resources to JORC 2012”, 14 September 2026. The production target comprises approximately 10.9 Mt of scheduled run-of-mine material, of which approximately 92% is derived from Indicated Mineral Resources and approximately 8% is derived from Inferred Mineral Resources, after applying mining modifying factors. There is a low level of geological confidence associated with Inferred Mineral Resources and there is no certainty that further exploration work will result in the determination of Indicated Mineral Resources or that the production target itself will be realised. The Inferred Mineral Resources underpin approximately 8% of the production target and are predominantly scheduled in later years of the mine plan, with only limited inferred material scheduled in earlier years. The Company has concluded that the Inferred component is not a determining factor in the viability of the development scenario and that the Scoping Study does not depend on Inferred Mineral Resources. Funding The Scoping Study estimates pre-production capital of approximately A$244.5 million, before taking into account sustaining capital or any additional funding requirements that may arise in connection with working capital, financing or other development requirements. Critica has not secured any of the funding required to develop the Project. The pre-production capital requirement is substantial relative to the Company’s current market capitalisation and existing financial resources, and the Company would need to obtain substantial additional external funding to develop the Project. There are risks that the Company will not be able to raise that amount of funding when needed, or at all. Any future funding may include (without limitation) one or a combination of debt, equity, strategic partner, offtake-linked, joint venture, partial sale or other commercial arrangements. If equity funding is required, existing shareholders may be diluted or their interests may otherwise be affected. Assumptions and accuracy The Scoping Study outcomes, production target and forecast financial information are based on the material assumptions and modifying factors set out in the Company’s ASX announcement dated 29 September 2026, including mine design, processing, metallurgical recoveries, capital and operating costs, commodity prices, exchange rates, approvals and funding. Capital and operating cost estimates carry an overall accuracy range of approximately -25% to +50%. Base Case processing recoveries of 75% tin, 85% WO₃ and 98% magnetite are modestly above recoveries demonstrated or estimated in individual historical testwork programs and have not all been demonstrated simultaneously in a single integrated locked-cycle test program. They remain subject to further metallurgical validation, variability testing and optimisation. Given the uncertainties involved, investors should not make investment decisions based solely on the results of the Scoping Study. critica.limited ASX: CRI October 2026 5 critica.limited ASX: CRI October 2026 C R I T I C A The Critica Investment Case Two strategic projects.
