Cautionary Statement – JORC Code (2012)

The Costa Fuego Copper-Gold Project is currently at the Pre-Feasibility Study ("PFS") stage. The production targets and forecast financial information contained in this report are based on technical and economic assessments that are preliminary in nature. While the PFS incorporates Measured, Indicated, and Inferred Mineral Resources, there is a lower level of geological confidence associated with Inferred Mineral Resources, and no certainty that further exploration or development will result in the conversion of Inferred Mineral Resources to Indicated or Measured categories.

The PFS is not a definitive study and is based on a number of assumptions, including commodity prices, capital and operating costs, metallurgical recoveries, permitting, and other factors, which are subject to change. The outcomes of the PFS should not be used as the basis for a final investment decision. Further work, including additional drilling, metallurgical testing, and detailed engineering, is required before the Company can make a decision to proceed to development.

Of the Mineral Resources scheduled for extraction in the PFS production plan, more than 99% are classified as Indicated, with the remaining <1% as Inferred. The Company has concluded that it has reasonable grounds for disclosing a production target which includes a small amount of Inferred Mineral Resources, as permitted under the JORC Code. 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 viability of the development scenario envisaged in the PFS does not depend on the inclusion of Inferred Mineral Resources. However, it is reasonably expected that the majority of Inferred Mineral Resources could be upgraded to Measured or Indicated Mineral Resource with continued drilling.

The Mineral Resources underpinning the production target in the PFS have been prepared by a competent person in accordance with the requirements of the JORC 2012. For full details on the Mineral Resource estimate, please refer to the ASX announcement of 27 March 2025.

To achieve the outcomes indicated in the PFS, including reaching Definitive Feasibility Study ("DFS"), mine construction and production stages, funding in the order of US$1.27 Billion will be required, including pre-production and working capital and assumed financing charges. Investors should note that that there is no certainty that Hot Chili will be able to raise that amount of funding when needed. One of the key assumptions is that the funding for the Project will be available when required and on acceptable terms. It is also possible that such funding may only be available on terms that may be dilutive to, or otherwise affect the value of, Hot Chili's existing shares. It is also possible that Hot Chili could pursue other value realisation strategies such as debt financing, a sale or partial sale of its interest in the Costa Fuego Copper Project and/or Huasco Water, sale of further royalties and/or streaming rights, sale of non-committed offtake rights, and sale of non-core assets.

The Company cautions that there is no certainty that the results or estimates contained in the PFS will be realised.

This Report contains forward-looking statements. Hot Chili has concluded that it has a reasonable basis for providing these forward-looking statements and believes it has a reasonable basis to expect it will be able to fund development of the Costa Fuego Copper Project. However, a number of factors could cause actual results or expectations to differ materially from the results expressed or implied in the forward-looking statements. Given the uncertainties involved, investors should not make any investment decisions based solely of the results of the PFS.

The Company is planning to commence diamond drilling planned for phase two to extend higher grade centres at depth.  Regulatory application for phase-two drilling access has been submitted and is progressing.

Baseline studies for a second Environmental Impact Assessment ("EIA") are ongoing to ensure timely integration of La Verde into Costa Fuego's potential future mine plan.

District-Scale Porphyry Cluster Potential Emerging at La Verde

Regional exploration activities reported during the quarter have identified multiple look-alike magnetic features adjacent to La Verde highlight potential for a broader district-scale porphyry system.

The integration of a 3D magnetic inversion model from ground magnetic data shows a spatial correlation between the mineralised tonalitic porphyry intrusion and a NNE-SSW trending weakly magnetic anomaly over La Verde. This magnetic anomaly sits within a localised circular magnetic-low feature. This relationship has been used to identify three additional circular magnetic-low features (lookalike targets) adjacent to La Verde, all of which are well-positioned at the intersection point of major regional structures (Figure 3).

In addition to the geophysical data, the Company has also completed 3D geochemical probability modelling using an extensive regional soil geochemistry programme (Figure 4).

This work has outlined three priority porphyry targets as outlined in Figure 3, with two of these porphyry targets concealed under shallow gravel cover (blind exploration opportunity).  Regulatory applications for access clearing are being progressed across these new target areas adjacent to La Verde.

Projects Registered for Priority Status by Chilean Ministry of Economy

On 30 April 2025, Hot Chili announced that its Costa Fuego Copper-Gold Project and Huasco Water Project in Chile had been officially registered with the Chilean Ministry of Economy's Office for Sustainable Project Management (GPS Division).

This registration grants the projects priority status as strategic investments, allowing them to benefit from streamlined administrative processes. Both projects met the government's criteria for sustainability-focused development and will now be subject to coordinated oversight aimed at expediting permitting and approvals. This includes the management of Hot Chili's second maritime concession application for Huasco Water and the upcoming EIA submissions for both projects.

Appointment of New Chair and Project Director

Hot Chili Limited announced on 7 May 2025 the appointment of Mr Stuart Mathews as Non-Executive Chair and Mr Alberto Cerda as Project Director, adding considerable strength to its leadership team heading into a pivotal stage of growth.

Mr Mathews brings over 32 years of international mining experience, including holding senior executive roles at Gold Fields where he oversaw operations delivering over one million ounces of gold annually and led the development of five mining projects from exploration to production.

Mr Cerda, a Chilean mining engineer with more than 40 years of experience, has held senior roles across major global mining companies including BHP, Barrick, and Glencore. He has directed numerous large-scale projects in Chile and abroad, most recently leading the Norte Abierto JV for Newmont and Barrick.

The combined expertise of the two new appointments will be instrumental in guiding Hot Chili through the final investment phase toward becoming a mid-tier copper-gold producer.
