Hot Chili Limited (ASX: HCH) (TSXV:HCH) (OTCQX: HHLKF) ("Hot Chili" or "Company") is pleased to announcefurther consolidation of the Cortadera copper-gold discovery in Chile.
The Company has succeeded in securing several new prospective mining rights at a recently held, government-run, public auction for the Huasco region of Chile. The new mining rights are located alongside mining rights of the recently announced (25 th November 2022) transaction with Antofagasta Minerals S.A. (AMSA).
Together, these new landholdings consolidate the western extension of Cortadera and allow Hot Chili to test a potentially much larger copper porphyry cluster.
Hot Chili has now secured four new large porphyry targets adjacent to the existing Cortadera resource (Cuerpo 1, 2 and 3), and added significant prospective strike length across two mineralised trends:
· Las Canas trend (+1.8km, N-S) - Three large porphyry targets including the Cuerpo 4 porphyry target (700m in strike length by 300m in width and drill confirmed, see announcement dated 25 th November 2022 for details of AMSA transaction)
· Cortadera trend (+1.1km, NW-SE) – One large porphyry target located directly along-strike from Cortadera on the Serrano fault, an important mineralising fault corridor connecting the Cortadera and Productora copper-gold deposits
The new landholding successfully acquired at auction contains the Cortadera trend extension and comprises seven mining rights covering 757 hectares. Three mining rights (Falla Maipo 2, 3, 4) were acquired for US$110,000 and the remaining four mining rights (CF 6, 7, 8, 9) were successfully awarded following forfeiture of overlapping third party mining rights.
Figures on the following pages outline the location of the new mining rights in relation to Cortadera.
Drilling across the western extension to Cortadera is planned to commence as soon as possible.
This recent strategic consolidation of the Cortadera porphyry deposit area has the potential to deliver another significant leg of resource growth to the Costa Fuego copper hub.
Further updates and announcements are expected in the lead-up to drill commencement.

Hot Chili Limited (ASX: HCH) (TSXV:HCH) (OTCQX: HHLKF) ("Hot Chili" or "Company") is pleased to provide details of a material transaction with Chilean copper major Antofagasta Minerals S.A. (AMSA).
Hot Chili has executed an Option Agreement enabling Hot Chili to acquire a 100% interest in AMSA's mining rights adjoining the western margin of Hot Chili's Cortadera copper-gold porphyry discovery, the centre-piece of the Company's Costa Fuego senior copper development in Chile.
This strategic option agreement consolidates the highly prospective AMSA mining rights, containing near-surface drill intersections of copper-gold porphyry mineralisation, with Hot Chili's contiguous Cortadera project.
Cortadera has been the growth engine for Hot Chili since the Company executed a transaction to acquire the project in 2019.
Cortadera's current Indicated resource of 471Mt grading 0.46% CuEq for 1.7Mt copper and 1.8Moz gold and Inferred resource of 108Mt grading 0.35% CuEq for an additional 0.3Mt copper and 0.3Moz gold (ASX announcement dated 31 st March 2022) is contained within three porphyry centres, trending NW-SE, over a strike extent of 2.3km.
The option enables the consolidation of Cortadera and near doubles the prospective strike length of the discovery, increasing the near term, material resource growth potential for Hot Chili.
AMSA's five mining rights cover 517 hectares and contain a large outcropping mineralised porphyry (Cuerpo 4 - 700m in strike length by 300m in width) with similar dimensions to Cortadera's main porphyry (Cuerpo 3) as well as other identified porphyry targets, trending N-S, over a prospective strike extent of approximately 1.8km.
In 2005, AMSA intersected significant copper-gold-molybdenum mineralisation at Cuerpo 4, with five shallow Reverse Circulation (RC) drill holes totalling 1,056m (Drilling data and associated drilling intersections not previously publicly reported, AMSA internal report, see JORC Code Table 1 in this announcement for further details).
Four of AMSA's five drill holes recorded wide intersections of mineralisation, including COR-03 which recorded 128m grading 0.5% CuEq (0.4% Cu & 0.1g/t Au) from 28m downhole depth, including 16m grading 1.3% CuEq (1% Cu & 0.5g/t Au) from 28m.
The historical drilling across Cuerpo 4 clearly demonstrates open pit resource growth potential, given the shallow nature of copper-gold-molybdenum mineralisation, and near-surface, copper-gold enrichment.
Next Steps – Rapid Resource Definition
A first-pass drilling programme comprising 16 holes for 6,000m is expected to start as soon as possible.
Drilling will test Cuerpo 4 and two other targets within AMSA's landholding using RC and Diamond (DD) drilling. Hot Chili and AMSA have agreed on the detail and staging of the planned drilling programme after a collaborative and detailed geological review by both companies' technical teams.
Drilling is also planned across Hot Chili's Cortadera North target, where earlier exploration drilling targeting a large surface molybdenum anomaly in 2020 intersected wide zones of silver mineralisation. This work vectored towards a sizeable copper-gold porphyry target (Cuerpo 4) on AMSA's adjacent mining right.
Hot Chili then ceased all exploration activities at Cortadera North until an agreement could be entered into with AMSA to enable Hot Chili to acquire the adjacent landholding.
Revision to Costa Fuego Growth and Development Timetable
The transaction provides the next step in Hot Chili's long term growth strategy. The AMSA mining rights provide relatively low cost and highly accretive resource growth potential due to their proximity to the Company's Cortadera open pit resource base.
Hot Chili's next resource update, which was proposed to be delivered in late 2022, is now expected to be finalised in H2 2023 to include the proposed drilling on the AMSA mining rights.
The combined Pre-feasibility Study (PFS) for Costa Fuego, studying targeted annual production rates of up to 100kt Cu and up to 70koz Au for a +20 year life of mine, will be paused until the Company can assess the impact of resource growth potential at Cortadera. The Company's decision to pivot the PFS ensures that future expenditure relating to the PFS can be optimised for infrastructure location and a potentially larger scale copper operation.
Only critical PFS workstreams will be continued to secure long-lead time items (environmental and social) and key value additions (metallurgical) to ensure Costa Fuego remains on-track to potentially be delivered into production in 2028.
A Preliminary Economic Assessment( PEA) of the combined Costa Fuego project at the current 20Mtpa sulphide concentrator study scale is now planned to be delivered in H1 2023.
Hot Chili aims to ensure that Costa Fuego's "clean and green" attributes, including low elevation/coastal location, proximity to existing infrastructure, access to renewable power, use of seawater for processing and a central processing strategy, can be leveraged with this consolidation and growth opportunity.
Costa Fuego remains one of a few front-runner, large copper development projects in the world that can be advanced to production in a timely manner due to Hot Chili's consolidation, development and permitting efforts over the last decade.
Recent positive developments in Chile's constitutional process and taxation review have reaffirmed Chile's stable and attractive standing as a top global mining investment jurisdiction.
Option Agreement to Acquire 100% Interest in AMSA's Cortadera Mining Rights
Under an Option Agreement (Option) between Frontera SpA ("Frontera" - 100% subsidiary of Hot Chili) and Antofagasta Minerals SA (AMSA), Frontera has the option to acquire a 100% interest in the AMSA mining rights adjoining Cortadera within a two-year period on the following terms:
· Completion of 6,000m of drilling of any type, and
· Upon completion of the 6,000m drill commitment, Payment of a US$1.5 million Option exercise price to acquire the AMSA's mining rights, and
· Following exercise of the Option, AMSA has the right to buy-back a 55% interest in the AMSA mining rights within 120 days of exercise of the Option, by repaying 55% of the Option exercise price and paying five times the exploration expenditure incurred during the option period.
This transaction represents a strategic consolidation of the Cortadera porphyry deposit area and has the potential to deliver relatively low-cost, organic resource growth to the Costa Fuego copper hub.
Hot Chili plans to commence systematic exploration and resource definition drilling across this new landholding addition at Cortadera as soon as possible.
The Directors thank AMSA for their commitment to work with Hot Chili and to enable the continued consolidation of a globally significant, emerging copper hub for the Vallenar region of Chile.
This announcement is authorised by the Board of Directors for release to ASX and TSX.

For Cortadera and Productora, significant intersections are calculated above a nominal cut-off grade of 0.2% Cu. Where appropriate, significant intersections may contain up to 30m down-hole distance of internal dilution (less than 0.2% Cu). Significant intersections are separated where internal dilution is greater than 30m down-hole distance. The selection of 0.2% Cu for significant intersection cut-off grade is aligned with marginal economic cut-off grade for bulk tonnage polymetallic copper deposits of similar grade in Chile and elsewhere in the world. Down-hole significant intersection widths are estimated to be at or around true-widths of mineralisation.

The Measured Resource comprises 730,000 tonnes of lake clay at a grade of 25.8% alumina (aluminium oxide, Al2O3) for a contained 189,000 tonnes of alumina (Table A). It is part of a much larger resource that includes Indicated and Inferred Resources within a unique deposit of high-grade alumina hosted in extremely fine-grained evaporite and clay minerals in the top two metres of two small dry salt lakes in the Lake Hope playa system (West Lake and East Lake, Figure 3 and ASX Release March 21st 2023).
The Measured Resource will underpin a maiden Probable or Proven Reserve Statement for an initial mine life of at least 15 years at the proposed benchmark production rate of 10,000 tonnes per annum of High Purity Alumina. The Reserve Statement is subject to further mining, metallurgical test work and economic studies that are part of the ongoing PFS (ASX Release October 9th 2024).
The larger resource underpins a potentially much longer mine life of at least 25 years, as reported in the Scoping Study on Lake Hope. The study showed that the project had very robust economics, with an after-tax Net Present Value (NPV8) of A$1.3 billion and one of the lowest operating costs per tonne of HPA globally (ASX Release November 9th, 2023). Impact confirms that all material assumptions underpinning the production target and forecast financial information in the Scoping Study continue to apply.
Figure 1. Location of Lake Hope Project E63/2086
The Mineral Resource estimate is shown in Table A and is reported in accordance with the requirements of the JORC Code 2012 by resource consultants H and S Consultants Pty Ltd (HSC) of Brisbane, Queensland. All details relevant to the Resource Estimate are given below and in the JORC Tables 1, 2 and 3 at the end of this report. Drill hole information and assay data have been reported previously (ASX Release 19th June 2023).
Table A. Lake Hope Alumina Mineral Resources.
About 60% of the Measured Resource lies within West Lake, over which Impact recently pegged a Mining Lease Application (ASX Release August 12th, 2024). When required, further low-cost push-tube sampling of the lake can significantly increase the size of the measured resource (Figure 2).
Figure 2. Lake Hope showing the push tube sampling method used to drill out the resource and an example of the lake clay from the push tube showing excellent sample recovery.
The alumina block grade distribution for the resources is shown in Figure 2. The grade increases towards the centre of the lakes, offering an opportunity for preferential mining of the higher-grade material in the early stages of any future mine development. Initial geometallurgical studies examining the variability of the mineral assemblages across the lakes have also been completed, and these are being incorporated into the mining schedules being prepared for the PFS.
Figure 2. Percentage (%) Alumina Block Grade Distribution for the Lake Hope Mineral Resources (Drill hole collars are shown as circles.)
The new Mineral Resource Estimate will be incorporated, as per the JORC 2012 Code, into the Pre- Feasibility Study for Lake Hope, which is nearing completion. Final reports from the engineering and design studies, mining schedules, and mining cost estimates, as well as from other contractors and consultants, are awaited. Some of these are expected in mid-December, and accordingly, the PFS is expected to be completed in Q1 2025.
Early Access to the CRC-P Research and Development Grant Funding
Impact recently announced that, in collaboration with CPC Engineering and the Mineral Recovery Research Centre (MRRC) at Edith Cowan University, it had been awarded a $2.87 million grant to commercialise its innovative process for producing High-Purity Alumina from Lake Hope (ASX Release October 22nd, 2024).
The grant is provided under the Federal Government’s Cooperative Research Centres Projects (CRC-P) program and is part of a more extensive research and development project designed to
provide Impact with the relevant information required to complete a Definitive Feasibility Study. A vital component of the grant funding will be to construct a pilot plant, which is an essential milestone for 2025, and this will provide consistent HPA samples for off-take and qualification trials.
