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 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 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.

SUMMARY OF OPERATIONAL ACTIVITIES

Higher-Grade Starter Pit Firming as a Standout Feature of La

Verde

The Company's ongoing focus on shallow infill and step-out drilling

across the up-dip extension of La Verde's high-grade core, continued

to deliver more outstanding results from Reverse Circulation (RC) drill

holes DKP053, DKP054, DKP056, and DKP058 (Figure 1 and Figure

2) during the quarter.

Numerous drilling intersections returned across the up-dip portion of

La Verde's high-grade core, all contain broad zones of higher-grade

(+0.7% CuEq) mineralisation from shallow depths. Importantly, assay

results are pending for nearby up-dip drillhole DKP052 (Figure 3),

results expected soon (see announcement dated 5 May 2026).

These ongoing shallow RC drill results further expand the footprint of

near-surface, higher-grade mineralisation and continue to strengthen

the scale and continuity of a significant, near-surface, enrichment

zone - capable of delivering a higher-grade starter pit opportunity for

Costa Fuego (Figure 4).

Expansion Drilling Delivering Continued Success

Diamond (DD) drilling assay results for step-out holes DKD044,

DKD049 and DKP028D also confirmed additional bulk tonnage

extensions and delivered further expansion of La Verde's high-grade

core (Figures 2 and 3) during the quarter.

Assay results from DKD044 returned a significant intersection of 391

m grading 0.51% CuEq (0.42% Cu, 0.11g/t Au) from surface, (Figure

1), including several higher-grade intervals, confirming broad and

continuous high-grade copper-gold mineralisation on the western side

of the high-grade core

DD hole DKD049 was designed as a 175 m step-out from DKD039 -

which recorded the highest-grade and widest drilling intersection to

date at La Verde (725 m grading 0.42% CuEq (0.36% Cu, 0.07 g/t Au

from 18m depth). Results from DKD049 confirm a significant

expansion of La Verde's eastern flank at depth.

DKP028D successfully extended a previous RC drillhole (which ended

in mineralisation), recording a further 200m down-hole of

mineralisation across La Verde's western flank.

Advancing Toward Maiden Mineral Resource and Pre-Feasibility

Study (PFS) Integration

Hydrogeological, geotechnical, metallurgical, mine engineering and

environmental workstreams are all advancing well toward full

integration of La Verde into the Company's Costa Fuego production

hub. Additional mineralogical analysis activities were also carried out

during the quarter, including Terraspec data collection and drill core

scanning using LithologyIQ's hyperspectral instrument.

A maiden Mineral Resource Estimate (MRE) for La Verde is expected

to be released later this year followed by a revised PFS for Costa

Fuego and then finally culminating in the formal submission of an

Environmental Impact Assessment for Costa Fuego in Q2CY 2027.

The Company expects that La Verde's rapid integration will be

transformative for Costa Fuego's financial metrics and global

standing, already ranked amongst the world's top five by-scale1,

independent copper developments, not controlled by a major

mining company.

Additional ISO Accredited Assay Laboratory Engaged

During the quarter, delivery of assay results increased to over 10

weeks in some cases. Hot Chili took proactive measures and engaged

the services of an additional ISO accredited laboratory in the region, to

ensure reporting of outstanding assay results is fast tracked, and

assay turnaround times are accelerated. Improved turnaround times

have been noted from both laboratories since the addition of a second

laboratory.

Project Development Advances

Hot Chili has established a dedicated project development team, led

by experienced project director Mr David Bayona, to advance the

Costa Fuego Project through its critical development phase. Under a

single governance framework, the team is overseeing delivery of the

Environmental Impact Assessment (EIA) and the revised Pre-

Feasibility Study (PFS) programs, coordinating engineering,

permitting, social performance, infrastructure, technical studies,

project controls, key service providers, and third-party stakeholders.

This organisational transition marks an important step in Hot Chili's

evolution from an exploration-focused company to a project

development and delivery organisation, strengthening readiness for

permitting, financing, detailed engineering and project execution. The

integrated structure improves decision-making, maintains alignment

across workstreams and enhances schedule discipline, positioning

Costa Fuego for successful execution.

Environmental Impact Assessment (EIA) On-Track

The Costa Fuego Environmental Impact Assessment (EIA) continues

to advance, supported by a comprehensive schedule that enables

weekly and monthly monitoring of progress, critical path activities, and

milestones across all environmental workstreams.

A key strategic decision adopted during the quarter was the

separation of the environmental permitting process into two

independent EIAs:

• EIA 1A - Huasco Water seawater intake, pumping and

distribution system

• EIA 1B - Costa Fuego Development Project.

This approach provides greater clarity for regulators, establishes

independent areas of influence for environmental assessment,

reduces duplication of baseline and impact evaluation work, and

aligns the seawater supply system with the development of the mining

project.

Key workstreams advanced during the quarter included environmental

baseline studies, community and stakeholder engagement, indigenous

engagement program, and preparation of the formal EIA

documentation.

Revised Pre-Feasibility (PFS2)

In May 2026, Hot Chili commenced workstreams toward delivery of a

significant revision of its 2025 Pre-Feasibility Study (PFS), aiming to

incorporate the La Verde Cu-Au discovery into the Costa Fuego

development strategy. The study remains on track and is being

progressed in parallel with the Environmental Impact Assessment (EIA

1B) program under a common project governance framework.

The revised study is assessing development options to improve

project economics, reduce execution risk and simplify project

delivery. Key areas of assessment include the integration of La Verde

and the potential development of a large open-pit mining scenario at

Cortadera as an alternative to the previously defined open-pit and

underground block cave operation for the later years of Costa Fuego's

mine plan.

Results from the study will support selection of the preferred

development pathway for Costa Fuego and provide greater clarity on

project scope, mining strategy, infrastructure requirements and project

economics.
