SUMMARY OF OPERATIONAL ACTIVITIES

Major High-Grade Extensions Continue at La Verde

Phase two diamond drilling continued during the quarter at the Company’s La Verde copper-gold (Cu-Au) porphyry discovery in Chile (La Verde). Drilling focused on continuing to expand the mineralised discovery footprint

Results were stronger than anticipated, with the depth extent doubling to 800 m from surface – significantly expanding the high-grade core laterally and up to surface.

A standout significant intersection of 725 m grading 0.42% CuEq¹ from 18 m depth has been recorded in diamond drill hole DKD039, which was collared on the western extent of La Verde’s discovery footprint (Figure 1), and intersected multiple wide zones of +0.6% CuEq¹ mineralisation from near surface (Figure 2 and 3).

As the most significant result to date at La Verde, importantly, DKD039 achieved two key objectives:

Further extended near-surface higher-grade mineralisation by approximately 60 m to the west – recording 22 m grading 0.71% CuEq¹ from 42 m depth within a wider intersection of 48 m grading 0.55% CuEq (0.50% Cu, 0.03 g/t Au) from 18 m depth, located immediately beneath shallow gravel cover, and
Confirmed a significant 200 m down-dip extension of La Verde’s high-grade core – recording 61 m grading 1.03% CuEq¹ (0.90% Cu, 0.18 g/t Au, 1.81g/t Ag) from 671 m in association with high Cu/Au, A+B vein abundances >5% and massive and disseminated chalcopyrite (Figure 2).

Continued expansion and integration of La Verde’s high-grade core into Costa Fuego’s resource base and mining inventory is a priority this year.

Higher-Grade Cu-Au Starter Pit Emerging

Diamond drilling at La Verde has continued to test the shallow up-dip potential of La Verde’s high-grade core, with significant intersections returned from drill holes DKD035, DKD036, DKD037 and DKD038.

A 450 m x 400 m higher-grade, near-surface copper-gold zone has been defined by thirteen significant intersection +0.6% CuEq at La Verde (Figure 4), including most recently:

DKD036 recorded 150 m grading 0.52% CuEq (0.37% Cu, 0.21 g/t Au) from 30 m depth
- Including 38 m grading 0.70% CuEq (0.55% Cu, 0.21 g/t Au) from 117 m, and
DKD035 recorded 220 m grading 0.47% CuEq (0.37% Cu, 0.14 g/t Au) from 38 m depth
- Including 68 m grading 0.64% CuEq (0.52% Cu, 0.15 g/t Au) from 187 m

Similar to previous near-surface drill intersections, these latest significant results commence immediately beneath shallow gravel cover, indicating the potential for simple, cost-effective overburden removal in a future open pit development.

These results have the potential to contribute to a higher-grade starter pit for the Costa Fuego mine schedule, significantly reducing payback and positively impacting key financial metrics of Hot Chili’s March 2025 Pre-Feasibility Study.

Confirming Bulk Tonnage Continuity

Further assay results reported during the quarter continue to confirm continuity of bulk tonnage mineralisation at La Verde, including:

DKD037 recorded 184 m grading 0.42% CuEq¹ (0.32% Cu, 0.12 g/t Au) from 105 m depth
- including 22 m grading 0.60% CuEq (0.48% Cu, 0.15 g/t Au) from 203 m
DKD038 recorded 221 m grading 0.37% CuEq¹ (0.29% Cu, 0.11 g/t Au) from 48 m depth
- including 45 m grading 0.51% CuEq (0.37% Cu, 0.19 g/t Au) from 53 m

Drill hole DKD037 was designed to target a gap between two higher-grade zones, with assay results now confirming expansion and continuity of mineralisation across this zone (Figure 2). The significant intersection from DKD038 also commences immediately beneath shallow gravel cover (Figure 3).

La Verde Footprint Expands Further

During the quarter the diamond drill rig also completed four diamond drill tails, extending the mineralisation footprint reached by the RC drilling in Phase 1, which ended in mineralisation.

Assay results from diamond drill tail DKP009D extended La Verde’s Cu-Au mineralisation footprint along the eastern flank of the discovery in the north (Figures 1 and 3). The drill hole was a 200 m diamond tail to earlier RC drill hole DKP009 and reported 68 m grading 0.42% CuEq (0.33% Cu, 0.11 g/t Au) from 354 m depth, extending mineralisation downhole of DKP009.

Similarly, diamond drill tail DKP012D extended the mineralisation footprint along the northern flank of the discovery. The drill hole was a 284 m diamond tail to earlier RC drill hole DKP012 and reported 132 m grading 0.36% CuEq (0.26% Cu, 0.05 g/t Au) from 306 m depth extending mineralisation downhole of DKP012. Several higher-grade zones were intercepted in the tail, confirming the system is still open and mineralised to the north and will be followed up with additional drilling along the interpreted NNE-trending structural corridor (Figure 2 and 4).

DKP006D and DKP021D extended the mineralisation along the eastern flank of the discovery in the south, with DKD021D recording an additional 54 m grading 0.42% CuEq (0.34% Cu, 0.11 g/t Au) from 593 m depth, including 19 m grading 0.66% CuEq (0.51% Cu, 0.21 g/t Au) from 593 m depth.

Including the new diamond tail extensions:

DKP009D now records 388 m grading 0.41% CuEq (0.32% Cu, 0.12 g/t Au) from 34 m
DKP012D now records 394 m grading 0.46% CuEq (0.35% Cu, 0.11g/t Au) from 44 m
DKP021D now records 194 m grading 0.32% CuEq (0.26% Cu, 0.06 g/t Au) from 284 m
DKP006D now records 110 m grading 0.39% CuEq (0.27% Cu, 0.15 g/t Au) from 76 m

Diamond drilling has been instrumental in development of an early “4D litho-structural model” by the Company, with the interpretation of multiple intrusive phases optimising drill target design. Hot Chili geologists are applying the same targeting strategies that proved successful at the Company’s nearby Cortadera Cu-Au porphyry Resource and anticipate these methods will continue to drive growth at La Verde.

¹Copper Equivalent (CuEq) reported for the drill hole intersections were calculated using the following 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 Metal Prices applied in the calculation were: Cu=4.50 USD/lb, Au=3,150 USD/oz, Mo=20 USD/lb, and Ag=30 USD/oz. The entirety of the intersection is assumed as fresh. The recovery and copper equivalent formula for La Verde uses Cortadera as a proxy, which is considered reasonable given both the similar mineralisation style and amenability testwork completed thus far at La Verde – Recoveries of 83% Cu, 56% Au, 83% Mo and 37% Ag. CuEq (%) = Cu(%) + 0.69 x Au(g/t) + 0.00044 x Mo(ppm) + 0.0043 x Ag(g/t).

Development Studies Progressing

Global engineering firm Ausenco – with offices in Chile and Australia – has been appointed as the lead engineering group to progress the Feasibility Study for the Costa Fuego project. The appointment follows a review of major engineering groups in Chile, with Ausenco’s impressive execution of engineering, procurement, construction and ramp-up of the nearby, similar-scale, coastal project Mantoverde, a key factor in the decision.

¹See Page 23 of this announcement for detail on the US$3.50 Cu and US$6.00 Cu conceptual open pit shells (Exploration Targets). Any potential tonnage and grade of the Exploration Target shown is conceptual in nature. There has been insufficient exploration to estimate a Mineral Resource within the target area, and it is uncertain if further exploration will result in the estimation of a Mineral Resource.

²Copper Equivalent (CuEq) reported for the drill hole intersections were calculated using the following 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 Metal Prices applied in the calculation were: Cu=4.50 USD/lb, Au=3,150 USD/oz, Mo=20 USD/lb, and Ag=30 USD/oz. The entirety of the intersection is assumed as fresh. The recovery and copper equivalent formula for La Verde uses Cortadera as a proxy, which is considered reasonable given both the similar mineralisation style and amenability testwork completed thus far at La Verde – Recoveries of 83% Cu, 56% Au, 83% Mo and 37% Ag. CuEq (%) = Cu(%) + 0.69 x Au(g/t) + 0.00044 x Mo(ppm) + 0.0043 x Ag(g/t).

Notes to Table 1: Significant intercepts for La Verde are reported above a nominal cut-off grade of 0.20% Cu. Reported intersections may include internal dilution (intervals below 0.20% Cu), including zones exceeding 30 m downhole width, where the overall weighted average grade of the intersection remains above the cut-off grade. Significant intersections are separated where zones of internal dilution result in discrete intervals that do not meet the reporting criteria. The selection of a 0.20% Cu cut-off grade is aligned with a marginal economic cut-off for bulk tonnage polymetallic copper deposits of comparable grade in Chile and globally. Significant intersection widths (interval) have been rounded to the nearest metre.

Qualifying Statements

The scientific and technical information relating to the Company’s Costa Fuego project in this report has been derived from or is based on the Costa Fuego Copper project pre-feasibility study (the “Costa Fuego PFS” or 2025 PFS), which has been prepared in accordance with Canadian regulatory requirements set out in National Instrument 43-101 – Standards of Disclosure for Mineral Projects (“NI 43-101”) and Joint Ore Reserves Committee of the Australasian Code for Reporting of Exploration Results, Mineral Resources and Ore Reserves prepared by the Joint Ore Reserves Committee of the Australasian Institute of Mining and Metallurgy, Australian Institute of Geoscientists and Minerals Council of Australia (the “JORC Code”) and reviewed and approved by the “Qualified Persons” as defined under NI 43-101 and “Competent Persons” as defined under the JORC Code, as set out below. The 2025 PFS was compiled by the Qualified Persons and Competent Persons listed below based on information available up to the effective date of the PFS. Additional details of responsibilities are provided at page 48 of presentation “Costa Fuego Preliminary Feasibility Study March 2025” released on March 27, 2025.

Conceptual Open Pit Shells

Conceptual open pit shells represent Exploration Targets as defined in the 2012 Edition of the ‘Australasian Code for Reporting of Exploration Results, Mineral Resources and Ore Reserves’ (JORC Code). They are based on completed exploration activities reported in the announcement released 19 May 2025 (‘Hot Chili Announces Latest Drill Results for La Verde, Doubling Porphyry Discovery Footprint’).

The conceptual open pit shells were generated using copper (Cu) prices of US$3.50/lb Cu and US$6.00/lb Cu on a series of nested Cu grade shells. Other input parameters informing the conceptual open-pit shells (pit slope angles, mining cost, processing cost, etc.) were derived from values reported in the March 2025 Costa Fuego Pre-feasibility Study and are considered appropriate for the style of mineralisation encountered at the La Verde Cu-Au porphyry discovery.

Any potential quantity and grade of the Exploration Target shown is conceptual in nature. There has been insufficient exploration to estimate a Mineral Resource within the target area, and it is uncertain if further exploration will result in the estimation of a Mineral Resource.

Further exploration activities are detailed in this announcement and include (but may not necessarily be limited to) a program of diamond drill holes aiming to extend the mineralised footprint at La Verde. Drilling commenced on 22 September 2025, with the length of the program dependent on a number of considerations including (but not limited to) the results of the exploration activities and regulatory applications and approvals.

Mineral Resource Statement

Costa Fuego Combined Mineral Resource (Effective Date 26 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 (29 November 2019) and reported in accordance CIM Definition Standards for Mineral Resources and Mineral Reserves (10 May 2014) that are incorporated by reference into NI 43-101.

2 Mineral Resources are inclusive of the Mineral Reserve

3 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), and 20% owned by Compañía Minera del Pacífico S.A (CMP).

4 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.

5 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 is party to an Option Agreement pursuant to which it can earn a 100% interest in the property.

6 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.

7 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.

8 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)

9 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.

10 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.

11 The effective date of the MRE is 26 February 2024. The MRE was previously reported in the 2024 PEA. Hot Chili Limited confirms it is not aware of any new information or data that materially affects the information included in the 2024 PEA and all material assumptions and technical parameters stated for the MRE in the 2024 PEA continue to apply and have not materially changed.

12 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 the 2025 PFS. A detailed list of Costa Fuego Project risks is included in Chapter 25 of the 2025 PFS Technical Report titled “Costa Fuego Copper Project NI43-101 Technical Report Preliminary Feasibility Study” and dated 9 May 2025 (effective 27 March 2025), is available on SEDAR+ (www.sedarplus.ca) and the Company’s website (www.hotchili.net.au).

Ore Reserve Statement

Costa Fuego Combined Ore Reserve (Effective Date 27 March 2025)

1 Mineral Reserves are reported on a 100% Basis – combining Mineral Reserve estimates for the Cortadera, Productora, Alice and San Antonio deposits, and have an effective date of 27 March 2025.

2 An Ore Reserve (declared in accordance with JORC Code 2012) was previously reported at Productora, a component of Costa Fuego, on 2nd March 2016 on the ASX. The Company was not subject to the requirements of NI 43-101 at that time.

3 Mineral Reserve estimation practices are in accordance with CIM Estimation of Mineral Resource and Mineral Reserve Best Practice Guidelines (29 November 2019) and reported in accordance CIM Definition Standards for Mineral Resources and Mineral Reserves (10 May 2014) that are incorporated by reference into NI 43-101. Mineral Reserve estimates are in accordance with the JORC Code. References to “Mineral Reserves” mean “Ore Reserves” as defined in the JORC Code and references to “Proven Mineral Reserves” mean “Proved Ore Reserves” as defined in the JORC Code.

4 The Mineral Reserve reported above was not additive to the Mineral Resource. The Mineral Reserve is based on the 26 February 2024 Mineral Resource.

5 Tonnages and grades are rounded to two significant figures. 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. As each number is rounded individually, the table may show apparent inconsistencies between the sum of rounded components and the corresponding rounded total.

6 Mineral Reserves are reported using long-term metal prices of US$4.30/lb Cu, US$2,280/oz Au, US$27/oz Ag, US$20/lb Mo.

7 The Mineral Reserve tonnages and grades are estimated and reported as delivered to plant (the point where material is delivered to the processing facility) and is therefore inclusive of ore loss and dilution.

8 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), and 20% owned by Compañía Minera del Pacífico S.A (CMP).

9 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.

10 The San Antonio deposit is controlled through Frontera (100% owned by Sociedad Minera El Corazón SpA, which is a 100% subsidiary of Hot Chili) and Frontera is party to an Option Agreement pursuant to which it can earn a 100% interest in the property.

11 The Mineral Reserve Estimate as of 27 March 2025 for Costa Fuego was prepared by Anton von Wielligh, Fellow with the AUSIMM (FAUSIMM). Mr. von Wielligh fulfils the requirements to be a “Qualified Person” within the meaning of NI 43-101 and is the Competent Person under JORC for the Mineral Reserve.

12 Hot Chili Limited is not aware of political, environmental, or other risks that could materially affect the potential development of the Mineral Reserves other than as disclosed in the 2025 PFS. A detailed list of Costa Fuego Project risks is included in Chapter 25 of the 2025 PFS Technical Report titled “Costa Fuego Copper Project NI43-101 Technical Report Preliminary Feasibility Study” and dated 9 May 2025 (effective 27 March 2025), is available on SEDAR+ (www.sedarplus.ca) and the Company’s website (www.hotchili.net.au).
