PERTH, Dec. 18, 2024 - Hot Chili Ltd. (ASX: HCH) (TSXV: HCH) (OTCQX: HHLKF) ("Hot Chili" or the "Company") is pleased to confirm a significant copper-gold discovery, located approximately 30km south of the Company's Costa Fuego Copper-Gold Project's ("Costa Fuego" or "the Project") planned central processing hub in the coastal range of the Atacama region, Chile.
Assay results for the first two drill holes of a 4,000m drill programme being undertaken across the recently secured La Verde porphyry copper-gold target have returned a wide drilling intersection of 202m grading 0.6% Cu, 0.3g/t Au from 70m depth within a broader intersection of 308m grading 0.5% Cu and 0.3g/t Au from 46m depth to end of hole.
La Verde is part of Hot Chili's recent consolidation of the Domeyko landholding where the Company earlier executed the La Verde Option Agreement (see announcement dated 11th November 2024), which for the first time consolidated and provided access to drill test a large potential porphyry copper target footprint.
The historical La Verde open pit mine was previously exploited by private interests for shallow porphyry copper-style oxide mineralisation with limited drill testing outside the central lease or to depth.
A total of twelve RC drill holes for approximately 3,150m are complete with results returned for the first two Reverse Circulation (RC) holes of the first-pass drill programme. The first two drill holes (DKP001 and DKP002) were designed to (1) validate historic drilling intercepts, and (2) test the interpreted northern extension of the porphyry from the previously exploited open pit, respectively.
Drill hole DKP001 was successful in validating the most notable copper intercept from historic exploration drill results, returning a broad significant intersection containing multiple higher-grade zones:
DKP001 returned 174m grading 0.4% Cu, 0.1g/t Au from 36m depth
- including 10m grading 0.6% Cu, 0.1g/t Au from 72m, and
- including 26m grading 0.5% Cu, 0.1g/t Au from 96m, and
- including 22m grading 0.6% Cu, 0.2g/t Au from 144m
Drill hole DKP002 was located approximately 120m southeast of DKP001, with assay results returning a drill intersection, that exceeded the Company's expectations and suggests potential for a higher- grade copper-gold zone within the La Verde porphyry:
A total of 308m grading 0.5% Cu, 0.3 g/t Au from 46m depth
- including 202m grading 0.6% Cu, 0.3 g/t Au from 70m depth,
- which includes 100m grading 0.7% Cu, 0.3 g/t Au from 118m depth
These consistent higher-grade results confirm the extension of the porphyry system almost 400m to the north-east of the open pit, a significant step out considering the existing pit measures approximately 200m x 400m. The higher-grade mineralisation is also located immediately beneath a gravel cover sequence which obscures the ultimate extent of the porphyry system. Oxide mineralisation is associated with copper clays and chalcocite up to approximately 80m vertical depth from surface with the primary sulphide mineralisation associated with chalcopyrite and pyrite.
Mineralisation appears to be open in all directions and where the system remains under cover.
Assay results are pending for ten RC drill holes, for which visual logging confirmed porphyry-style mineralisation associated with A- and B-type porphyry veining. Preliminary geological modelling indicates a +1% A + B vein footprint of ~850 m by ~700 m (refer to Figure 3a), based on detailed surface mapping and downhole logging.
The La Verde footprint is comparable to the +1% A + B vein footprint at Cuerpo 3 (1,000m by 750m) at the Company's Cortadera porphyry copper-gold deposit, located 30km to the north (refer to Figure 3b). Cuerpo 3 is the largest of Cortadera's three porphyries, a cornerstone to Costa Fuego's Indicated mineral resource base of 798Mt grading 0.45% CuEq for 3.6Mt Cu and 3.0Moz Au1 and Inferred2 mineral resource of 203Mt grading 0.31% CuEq for 0.5Mt Cu and 0.4Moz Au.
The Company is particularly pleased with the high gold to copper ratio returned in drill hole DKP002 with additional results pending.
Hot Chili has expanded the first-pass RC drill programme with an additional 2,000m planned, now expected to be complete in late January 2025.
Hot Chili has a strong balance sheet with A$25.7 million in cash (as of 30 September 2024) and continues to advance two key development milestones planned for release in the first quarter of 2025 - Costa Fuego PFS and Water Supply Business Case Study PFS.
The Company looks forward to providing further updates as additional drill results are returned and exploration drilling activities progress at La Verde.

| Notes to Table 1: Significant intercepts for La Verde 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. |

Mineral Resource Statement
Costa Fuego Combined Mineral Resource (Effective Date 26th February 2024)
| 1 Mineral Resources are reported on a 100% Basis - combining Mineral Resource estimates for the Cortadera, Productora, Alice and San Antonio deposits. All figures are rounded, reported to appropriate significant figures and reported in accordance with the Joint Ore Reserves Committee Code (2012) and NI 43-101. Mineral Resource estimation practices are in accordance with CIM Estimation of Mineral Resource and Mineral Reserve Best Practice Guidelines (November 29, 2019) and reported in accordance CIM Definition Standards for Mineral Resources and Mineral Reserves (May 10, 2014) that are incorporated by reference into NI 43-101. |
| 2 The Productora deposit is 100% owned by Chilean incorporated company Sociedad Minera El Aguila SpA (SMEA). SMEA is a joint venture (JV) company - 80% owned by Sociedad Minera El Corazón SpA (a 100% subsidiary of Hot Chili Limited), and 20% owned by Compañía Minera del Pacífico S.A (CMP). |
| 3 The Cortadera deposit is controlled by a Chilean incorporated company Sociedad Minera La Frontera SpA (Frontera). Frontera is a subsidiary company - 100% owned by Sociedad Minera El Corazón SpA, which is a 100% subsidiary of Hot Chili Limited. |
| 4 The San Antonio deposit is controlled through Frontera (100% owned by Sociedad Minera El Corazón SpA, which is a 100% subsidiary of Hot Chili Limited) and Frontera has an Option Agreement to earn a 100% interest. |
| 5 The Mineral Resource Estimates (MRE) in the tables above form coherent bodies of mineralisation that are considered amenable to a combination of open pit and underground extraction methods based on the following parameters: Base Case Metal Prices: Copper US$ 3.00/lb, Gold US$ 1,700/oz, Molybdenum US$ 14/lb, and Silver US$20/oz. |
| 6 All MRE were assessed for Reasonable Prospects of Eventual Economic Extraction (RPEEE) using both Open Pit and Block Cave Extraction mining methods at Cortadera and Open Pit mining methods at the Productora, Alice and San Antonio deposits. |
| 7 Metallurgical recovery averages for each deposit consider Indicated + Inferred material and are weighted to combine sulphide flotation and oxide leaching performance. Process recoveries: Cortadera - Weighted recoveries of 82% Cu, 55% Au, 81% Mo and 36% Ag. CuEq(%) = Cu(%) + 0.55 x Au(g/t) + 0.00046 x Mo(ppm) + 0.0043 x Ag(g/t) |
| San Antonio - Weighted recoveries of 85% Cu, 66% Au, 80% Mo and 63% Ag. CuEq(%) = Cu(%) + 0.64 x Au(g/t) + 0.00044 x Mo(ppm) + 0.0072 x Ag(g/t) Alice - Weighted recoveries of 81% Cu, 47% Au, 52% Mo and 37% Ag. CuEq(%) = Cu(%) + 0.48 x Au(g/t) + 0.00030 x Mo(ppm) + 0.0044 x Ag(g/t) Productora - Weighted recoveries of 84% Cu, 47% Au, 48% Mo and 18% Ag. CuEq(%) = Cu(%) + 0.46 x Au(g/t) + 0.00026 x Mo(ppm) + 0.0021 x Ag(g/t) Costa Fuego - Recoveries of 83% Cu, 53% Au, 71% Mo and 26% Ag. CuEq(%) = Cu(%) + 0.53 x Au(g/t) + 0.00040 x Mo(ppm) + 0.0030 x Ag(g/t) |
| 8 Copper Equivalent (CuEq) grades are calculated based on the formula: CuEq% = ((Cu% × Cu price 1% per tonne × Cu_recovery) + (Mo ppm × Mo price per g/t × Mo_recovery) + (Au ppm |
| × Au price per g/t × Au_recovery) + (Ag ppm × Ag price per g/t × Ag_recovery)) / (Cu price 1% per tonne × Cu recovery). The base case cut-off grade for Mineral Resources considered amenable to open pit extraction methods at the Cortadera, Productora, Alice and San Antonio deposits is 0.20% CuEq, while the cut-off grade for Mineral Resources considered amenable to underground extraction methods at the Cortadera deposit is 0.27% CuEq. It is the Company's opinion that all the elements included in the CuEq calculation have a reasonable potential to be recovered and sold. |
| 9 Mineral Resources are not Mineral Reserves and do not have demonstrated economic viability. The MRE include Inferred Mineral Resources that are considered too speculative geologically to have economic considerations applied to them that would enable them to be categorised as Mineral Reserves. It is reasonably expected that the majority of Inferred mineral resources could be upgraded to Measured or Indicated Mineral Resources with continued exploration. |
| 10 The effective date of the MRE is February 26th, 2024. The MRE were previously reported in Hot Chili's ASX announcement released February 26th, 2024 "Hot Chili Indicated Resource at Costa Fuego Copper-Gold Project Increases to 798 Mt" (Resource Announcement). Hot Chili confirms it is not aware of any new information or data that materially affects the information included in the Resource Announcement and all material assumptions and technical parameters stated for the MRE in the Resource Announcement continue to apply and have not materially changed. |
| 11 Hot Chili Limited is not aware of political, environmental, or other risks that could materially affect the potential development of the Mineral Resources other than as disclosed in this Report. A detailed list of Costa Fuego Project risks is included in Chapter 25.12 of the Technical Report "Costa Fuego Copper Project - NI 43-101 Technical Report Mineral Resource Estimate Update" dated April 8th, 2024. |
