CORRECTION – Hot Chili Announces PFS for Huasco Water & MOU for Seawater Supply to Costa Fuego

Hot Chili Limited (ASX: HCH) (TSXV: HCH) (OTCQX: HHLKF) (“Hot Chili” or the “Company”) is providing corrections to yesterday's news release announcing the Preliminary Feasibility Study (“PFS”) for Huasco Water, an 80% owned entity that controls strategic water rights in the Huasco Valley of Chile. The minor corrections are with respect to certain figures that did not align with the correct version that was previously announced on the Australian Stock Exchange.

Highlights

Strong EconomicsforaLarge,Multi-User,WaterBusiness

— Stage 11 Water Supply Preliminary Feasibility Study (PFS) for 500L/s of Potential Seawater Supply: Post-tax Net Present Value (NPV8%) of US$122 million and Internal Rate of Return (IRR) of 19%. Construction capital cost for seawater supply estimated at US$151 million with a 4.5-year payback

— Stage 2 Water Supply PFS for 1,300 L/s of Potential Desalinated Water Supply: Post-tax NPV8% of US$977 million and IRR of 19%. Construction capital cost for desalinated water supply estimated at US$1.4 billion with a 4- year payback. Stage 2 financial outcomes include Stage 1 capital and operating cashflows

— Stage 3 Conceptual Study for Expansion to 2,300 L/s of Potential Desalinated Water Supply

Stage 1-Multi-DecadeSeawater SupplytoCostaFuego

— 20 Year Seawater Supply with Foundation Off-taker: Memorandum of Understanding (MOU) executed for water supply of up to 500 L/s to Hot Chili's Costa Fuego Copper-Gold Project (Costa Fuego)

— Long Lead-times Permits Secured: Granted maritime water concession to extract seawater, permit for coastal land access, Stage 1 pipeline easements and connection to the electrical grid secured

— Near-Term Development Decision Tied to Costa Fuego: First water supply planned for end of decade

Stage2and3-Regional,DesalinatedWaterSupplyOpportunity

— Large Catchment of Potential Off-takers: Over 4,000 L/s of desalinated water demand identified, including six undeveloped mining projects without secured access to desalinated water supply. No offtake agreements have been secured for stage 2 or 3 and discussions with potential customers are ongoing.

— Staged Growth Approach: Establishment of seawater supply infrastructure toward the end of the decade, followed by the commencement of initial desalinated water supply shortly thereafter, and subsequent staged expansion. The staged approach enables long term scalable water supply to support mining, community, and agriculture in the Huasco Valley region with potential to extend well beyond the initial project horizons

First-MoverAdvantage

— Only Active Maritime License: HW Aguas para El Huasco SpA (“Huasco Water”), a joint venture between Hot Chili (80% interest) and Compañia Minera Del Pacifico “”CMP” (20% interest), is the only company with permitted access to supply seawater in the Huasco Valley region following a ten-year regulatory approval process

— Desalination Permitting Advancing: Over a year advanced on regulatory applications to enable the supply of desalinated water from the existing maritime concession and a second maritime concession application by Huasco Water

— Long Permitting Timelines Continue: No regulatory changes have been made to Chile's maritime permitting process since Huasco Water was granted its concession. Hot Chili maintains a competitive advantage as the first mover in the area for a water distribution business.

— Environmental Impact Assessment (EIA) Advanced: Stage 1 seawater supply is included within the Costa Fuego EIA, baseline studies complete.

Customer Base

Huasco Water is the only company with permitted access to supply industrial scale seawater to the Huasco Valley region.Huasco Water is also advanced in its permitting application to enable its existing maritime concession to be upgraded to provide desalinated water.

The current maritime concession regulatory process in Chile is long, as evidenced by Hot Chili's 10-year lead time to secure its maritime concession. This combined with the current regulatory environment, restricting the use of continental water in the AtacamaregionofChile, placesHuascoWater's waterassetsasakeyenabler for industrial scale water supply to the Huasco Valley region.

Watersupply networksaretypically boundbyareas of influencerelatedtowatertransmission distancefrom intake. This distance has been determined by Huasco Water's independent consulting experts as an area defined by 75km north and 75km south of Huasco Waters permitted water intake location.Potential alternativefar-field watersupplynetworks fromthenorth (Copiapo)orsouth(LaSerena) havebeenassessed anddeterminedtobeeconomicallychallenged(fromtheperspectiveofcapitalandoperatingcost)toprovide water supply to the Huasco Valley region.

All parties identified in the water demand table for stage 2 and 3 require desalinated water supply in order to develop their projects and are engaged in ongoing discussions with HuascoWaterconcerningpotential water supply solutions.

All project development timeframes have been sourced from publicly available information and from direct discussion with each potential customer to determine a schedule of potential water supply. MOU's to study and negotiate off-take arrangements for 165 L/s of desalinated water demand for stage 2 have been executed with private parties (Agrosuper and Nutram) in the Huasco Valley already and further MOU's are expected to be executed in cooperation with other potential off-takers.

Rising global demand for copper is translating to rising long-term consensus price for copper.The Huasco Valley region represents one of the largest groupings of major undeveloped copper projects in the world and is attracting significant capital investment.

There are currently no other alternatives to industrial scale water supply for the Huasco Valley region over the next ten years given current regulatory timeframes. Given global copper supply and demand fundamentals, it is expected that the majority of these projects will advance into production should copper incentive price be sufficient and water supply be available within the coming ten-year period.

Huasco Water's approach to developing a regional multi-user water network to reduce environmental and social impacts and drive commercial and community synergies is aligned with the Chilean government's approach to addressing water scarcity in the Atacama region.

Whileapproximately4,000L/sofpotentialdesalinateddemandhasbeenidentifiedfromundevelopedmineral resource projects intheHuasco Valley area of influence, only 1,300 L/s in stage 2 and 2,300 L/s of demand in stage 3 have been forecast.

Huasco Water has determined that these projects, their forecast demand and timing are considered reasonable grounds for forecasts as determined by independent water industry expert reports (PFS engineering report) commissioned by Huasco Water and taking into consideration direct discussions with potential customers.

Basis for Financial Forecasts

The basis for forecasting the tariff (or price) that customers pay for water supply is as follows:

Ourindependentwaterindustryexpert report(PFS engineering report) outlined engineering designs for water transmission for Stage 1, Stage 2 and Stage 3 and designs werecosted for construction and operation. Capital and operating costs formed the basis of the tariff estimation, with the fixed tariff established to service capital cost repayment and the variable tariff established to service operating costs to supply. Capital and operating cashflows and discount rate are combined to estimate the levelised cost of water for each stage and client.

For the Huasco Water PFS financial model, the capital and operating cashflows require a margin to make a minimum return on capital investment. The combination of cost and margin produce a tariff that is specific to each client and represents the price of water supply to the location of their demand. The tariff is estimated to a value that will produce a target IRRforHuasco Water.ForahigherorlowerIRRtarget,ahigherorlower tariff is estimated that achieves target IRR and provides a sensitivity range of water price for the financial model forecast.

AreasonablerangeofIRR valueswasdefinedfromconsultationwithindependent waterindustryexpertsas being from 12% to 19% and these returns form the basis of the range of tariffs presented in Table 1.

Waterprices areestimatedusingthisapproach insteadof amarket based,long-term priceforecastasthere is no existing market for water supply in the Huasco Valley region.

Given potential earnings forecasts are for periods of more than two-years, financial forecasts have been supported by independent water industry expert reports and are considered by the Company as being objectively verifiable sources of information.

The Company has formed the view that there is a reasonable basis to believe that requisite future funding for developmentoftheHuascoWaterProjectwillbeavailable whenrequired.The WaterStudyPFSdemonstrates that the Project has robust technical and economic fundamentals for Stage 1, having regard for an MOU executed with Hot Chili Limited with tariff costs already incorporated in the Water Study PFS as of the date thereof.

The Company has received significant interest in Huasco Water from both Chilean and international water investment groups in additionto severalneighbouring minedevelopers, agriculturalgroups, community groups and government to support the reasonable prospects for funding of Stage 2. Stage 3 remains at a conceptual level of study.

The Company notes that it's approach to potentially outsourcing its water infrastructure aims to provide capital costsavingsandprojectfinance optionality.ThereisanincreasingtrendinChilean miningtowardsoutsourcing of water supply to the industrial infrastructure sector.

Hot Chili notes other transactions for funding of water infrastructure projects such as that reported in Chile on 29 August 20241that Chilean power generation company Colbún has formed a strategic alliance with Desala Petorca,aseawaterdesalinationprojectinRegion Vdesignedtobeamulti-clientsupplier ofdesalinatedwater. Colbúnhascommittedinvestmenttocontinuewiththedevelopmentphaseandhastakencontrol oftheproject's investment vehicle. Icafal, one of the largest construction companies in Chile, has joined as a minority partner.

Petorca will supply water to Los Andes Copper's Vizcachitas copper project under a 2022 letter of intent, in which the developer agreed to become an anchor client for the desalination project's development.

This follows earlier newsthat copper mining major AntofogastaMinerals announced2on 5 June 2024 that they had sold their water assets and water rights to the Centinella copper mine for US$600 million to a consortium (Transelec and Almar Water), which will also Finance, Build, Own, Operate (BOO) and sell seawater for the Centinella mine expansion.

Hot Chili's approach to monetising it's water assets through potential sell down of it's 80% interest in Huasco Water to potential Chilean or international water infrastructure investment groups aims to assist in financing of the Company's Costa Fuego project while also facilitating funding of Huasco Water's potential regional water supply business. The Company is in ongoing discussions with several potential Chilean and international water infrastructure investment groups in this regard.

IdentifiedRisks

ThePFS processidentifiedthefollowingrisks:

Demand Risks

— Forecast demand of water from the identified customer base may not be realised as assumed within the PFS

— Timing of demand of water from the identified customer base may not be realised as assumed within the PFS

EnvironmentalandRegulatoryRisks

— Potential delays in obtaining environmental and sectoral permits.

— Community opposition due to perceived environmental impacts of the water intake or desalination system.

— Regulatory changes affecting maritime concessions or brine discharge standards.

Technical Risks

— Challenges in aligning designs produced by different consulting firms (ILF/Wood).

— Topographical and hydraulic uncertainties, particularly in high-altitude areas.

Financial Risks

— Volatility in investment and operational costs.

— Reliance on securing new client contracts to validate project expansions.

Operational Risks

— Challenges in operations due to complex geography or adverse climatic conditions.

— Exposure to natural hazards, such as earthquakes and tsunamis, impacting marine infrastructure.

Risk Mitigation Strategies

ThePFS processidentifiedthefollowingriskmitigationstrategies:

Demand Risks

— Financing and construction are contingent upon contractual offtake agreements

— Stage 1 supply will underpin the establishment of the Huasco Water business, in advance of contractual supply from Stage 2 customers

DesignIntegration

— Continuous technical coordination between consulting firms to ensure seamless integration of project designs.

Layout and Hydraulic Validation

— Technical validation of the proposed layout and hydraulic requirements during Stage 3.

Regulatory Compliance

— Early initiation of the modification process for the existing maritime concession.

Environmental Approvals

— Phased submission of Environmental Impact Studies Costa Fuego scheduled for 2026, followed by Huasco Water Stage 2.

Contractual Stability

— Execution of Water Purchase Agreement contracts with firm commitments to underpin expected demand projections.

Second sea water concession to mitigate upgrade of existing concession or change of use to brine discharge

— North and south route assessments to mitigate the risk of easements being agreed across the southern route which is preferred on the basis of cost of delivery.

— Below ground pipe costing for Stage 1/2/3 to improve likelihood of approvals.

Strategic Opportunities

ThePFS processidentifiedthefollowingstrategic opportunities:

Pioneering Initiative

— The project benefits from an existing maritime concession, significantly reducing lead times and regulatory challenges.

Multi-Client Integration

— In Stages 2 and 3, the project enables the integration of industrial, community, and agro-industrial water demands, establishing a consolidated multi-client solution.

Economies of Scale

— By replacing multiple individual water intake and desalination systems, the project achieves cost efficiencies.

Sustainability Potential

— The system offers the feasibility of integrating renewable energy sources for pumping operations, contributing to a reduced carbon footprint.

Community Opportunity & Regional Water Security

— The project enhances water security across the region, delivering a positive impact on local communities.
