The newly discovered nickel system, known as the "Umburana System", is located approximately 20 kilometers from the Company's existing Caraíba processing facilities. The system was discovered using new detailed field mapping and soil geochemistry collected during the Company's 2021 and 2022 exploration programs in conjunction with the Company's airborne electromagnetic ("AEM") survey. First-pass drilling comprised of 48 drill holes initially testing where ultramafic rocks have been mapped at surface. The ongoing program has identified large intervals of disseminated and interstitial nickel sulphides as well as zones of high-grade semi-massive (containing approximately 30% to 60% sulphides) and massive sulphides (containing approximately 60% to 80% sulphides), with massive sulphide intercepts up to 1.5 meters in thickness grading up to 6.59% nickel (7.11% NiEq). Nickel mineralization outcrops at surface, is evident in trenches and remains open down-plunge. Maximum depth of drilling to date is approximately 300 meters below surface. There are four exploration drill rigs currently operating on the system.

Commenting on the discovery, David Strang, Chief Executive Officer, said "This is a significant and pivotal moment for the Company and, more broadly, for the region. To think that copper in the Curaçá Valley was first documented in the late 1700s and we are just now discovering nickel sulphide mineralization not far from where copper has been mined for over 40 years is truly remarkable. As a Company, we have been working to better understand the potential for nickel occurrences since first observed within the Vermelhos Mine in 2018. With newly compiled datasets, dedicated resources focused exclusively on understanding and finding nickel and a complete re-look of several historic datasets this past year, our efforts and persistence have paid off. We believe today's results confirm the Curaçá Valley's potential to be a globally significant magmatic sulphide district for both copper and nickel."

Mike Richard, the Company's Chief Geological Officer, added "From my perspective, this is the most significant development in the Curaçá Valley's regional exploration program to date. I am incredibly proud of our exploration team for their contributions to making our first nickel discovery and believe we are at the early stages of unlocking significant value for the Company. These zones are the first targets we have drill tested in what is an emerging new exploration frontier, and based upon results to date, we have good geological evidence to support the "key" signatures for nickel potential that we expect will vastly enhance our nickel exploration program in the months and years ahead."

TECHNICAL DISCUSSION

The first significant documented occurrence of nickel sulphides in the Curaçá Valley was made by the Company during the Vermelhos Mine development, and later in discrete zones of copper-nickel massive sulphides within the Siriema Deposit in late 2018 and 2019, respectively. Detailed geologic mapping, comprehensive multi-element soil geochemistry and re-interpretation of the Company's available geophysical datasets throughout 2021 and the first-half of 2022 has resulted in the discovery of a new nickel system featuring favourable geology with coincident geochemical and geophysical anomalies. To date, detailed exploration has focused on two target areas located at the interpreted northeast and southwest boundary of a five-kilometer system each characterized by multiple expressions of outcropping nickel mineralization in the form of gossans, geochemical and geophysical anomalies - all associated with mafic-ultramafic intrusions. Please refer to Figure 3 for a plan view map of the Umburana System.

Initial drill-testing at the northeast and southwest boundaries of the currently known system has identified nickel sulphide mineralization ranging from disseminated and interstitial nickel sulphides (containing less than 10% sulphides) extending over 50 meters in thickness to patchy net-textured sulphides (containing approximately 10% to 30% sulphides) with localized centimeter up to 1.5 meter thick massive-sulphide lenses (containing approximately 60% to 80% sulphides) grading up to 6.59% nickel (7.11% NiEq). Mineralization within these zones is hosted by pyroxenite and peridotite ultramafic rocks. Sulphide minerals are mainly pyrrhotite, pentlandite (loop-textured where massive sulphide, see Figure 1) with lesser pyrite and chalcopyrite. Loop-textured pentlandite is an important geologic indicator commonly observed in magmatic nickel sulphide deposits. The full extent of the system is unknown at this time. Mineralization remains open down-dip and along strike. Exploration work remains ongoing.

No metallurgical testwork has been completed to date. Metallurgical samples from select drillhole composites within the Umburana System are currently being collected for preliminary testwork including detailed mineralogy as well as laboratory flotation tests. Where applicable, nickel equivalent ("NiEq") in this press release has been calculated using the following formula: NiEq = Ni + (Cu x $3.50/$9.80) + (Co x $25.50/$9.80). No adjustment for metallurgical recoveries has been made when calculating NiEq.

VB Zone

At the northeast extent of the Umburana System nickel-bearing ultramafic rocks have been identified over 1.4 kilometers north-south and up to 200 meters east-west using surface mapping supported by soil geochemistry and 20 trenches. To date, 24 holes with assay results have been received. Mineralization within the VB Zone is primarily comprised of disseminated, and patchy net-textured nickel sulphide mineralization with zones of high- grade massive sulphide mineralization featuring localized thickening of up to 1.5 meters grading up to 6.59% nickel (7.11% NiEq). Within the VB Zone, higher-grade mineralization appears to be focused at the base of a pyroxenite intrusion. Mineralization occurs predominantly within orthopyroxenites ranging from isotropic to locally banded.

Within the central high-grade portion of the VB Zone, results are highlighted by two holes, VB-05 and VB-17, both located on the same section, which intercepted high-grade massive sulphides of up to 1.5 meters grading up to 7.11% NiEq within broader mineralized intervals ranging between approximately 17 and 20 meters grading between 0.75% NiEq to 1.37% NiEq. Please see "VB Zone Intercepts" table below for complete results.

The deepest drilling to date within the VB Zone is highlighted by hole VB-25 that intercepted high-grade massive sulphide of up to 1.4 meters grading up to 5.30% NiEq, approximately 290 meters below surface. When combined with surface trenching and previously highlighted intercepts in hole VB-05 and hole VB-17, high-grade nickel sulphide mineralization can be traced from surface to over 300 meters down-dip. Additional exploration work to understand the relationship between these high-grade massive sulphide intercepts and other intercepts of high-grade nickel mineralization identified throughout the VB Zone remains ongoing.

There are currently three drill rigs active within the VB Zone. Please see Figures 4 and 5 for additional details on drill hole locations and intercepts.

LZ Zone

At the southwest extent of the Umburana System, located approximately 20 kilometers from the Company's Caraíba milling operations and approximately 3.2 kilometers southwest of the VB Zone, nickel-bearing ultramafic rocks have been identified over 500 meters in strike- length and approximately 50 meters in apparent thickness using surface mapping supported by geochemistry, AEM response and eight trenches. To date, 24 holes with assay results have been received. Mineralization within the LZ Zone is primarily comprised of disseminated nickel sulphide mineralization with intercalated intervals of interstitial and net-textured sulphides (see Figure 2). Within the 500-meter identified strike length of the LZ Zone, a zone of higher- grade mineralization has been identified within the footwall of the mafic-ultramafic intrusion associated with a peridotite layer.

Results within the footwall of the LZ Zone are highlighted by two holes, LZ-03 and LZ-07, both located on the same section, which intercepted broad mineralized intervals between 18 and 24 meters grading between 0.97% NiEq to 1.14% NiEq. South along strike, hole LZ-06, drilled approximately 50 meters from holes LZ-03 and LZ-07, intercepted 22.5 meters grading 1.02% NiEq. When combined with surface trenching, higher-grade mineralization within the footwall of the LZ Zone can be traced from surface approximately 190 meters down-dip. Please see "LZ Zone Intercepts" table below for complete results.

The deepest drilling to date within the LZ Zone is highlighted by hole LZ-24 that intercepted broad mineralization over approximately 46 meters grading 0.27% NiEq from approximately 185 meters downhole. At the bottom of this broader mineralized intercept, an extension of the high-grade peridotite layer of the footwall zone, approximately 200 meters below surface, was intercepted over 5.7 meters grading 1.08% NiEq indicating the footwall zone remains open along strike to the north and to depth. Hole LZ-24 is located approximately 50 meters north of the higher-grade mineralization identified in the footwall highlighted by holes LZ-03 and LZ-07, and approximately 100 meters north of the footwall intercept in hole LZ-06. Exploration drilling to understand the relationship between these higher-grade intercepts remains ongoing, and there is currently 1 drill rig working within the LZ Zone. In parallel, exploration efforts at the LZ Zone continue to use systematic geological mapping, trenching, ground electromagnetic ("EM") surveys and borehole EM surveys.

Please see Figure 6 and 7 for additional details on drill hole locations and intercepts.

NOTE ON NI 43-101 COMPLIANT TECHNICAL REPORT(S)

The conversion of drill results presented in this press release into NI 43-101 compliant mineral resources and mineral reserves all require additional work and analysis that remains ongoing. To date, there has been insufficient exploration and accompanying analysis to define a mineral resource and it is uncertain if further exploration will result in this nickel system being delineated as a mineral resource. Accordingly, the results herein may not be included in future NI 43-101 compliant mineral resources or mineral reserves depending on the results of this additional work and analysis, and other technical and/or economic reasons.

QUALITY ASSURANCE & QUALITY CONTROL

In support of its ongoing Umburana System exploration program, the Company is currently drilling on surface using third-party contracted core drill rigs. During the period from January 2022 through September 2022, third-party drill rigs were operated by Major Drilling do Brasil Ltda., and Layne Christensen Co. both of whom are independent of the Company. Drill core is logged, photographed and split in half using a diamond core saw at the secure core logging and storage facilities of Mineração Caraíba S.A. ("MCSA"). Half of the drill core is retained on site and the other half core is used for analysis, with samples collected on one- meter sample intervals unless an interval crosses a geological contact. All sample preparation is performed in MCSA's secure on-site laboratory. Total nickel and copper is determined using a nitric-hydrochloric acid digestion and Atomic Absorption Spectrometry and/or Titration at the on-site laboratory. All sample results during the period have been monitored through a QA/QC program that includes the insertion of certified standards, blanks, and pulp and reject duplicate samples. Check-assays for nickel and copper were submitted to ALS Brasil Ltda's facility located in Vespasiano, Minas Gerais, Brazil, at a rate of approximately 5%. ALS Brasil Ltda is a subsidiary of ALS Limited and is independent of the Company.

CAUTIONARY NOTES REGARDING MINERAL RESOURCE AND MINERAL RESERVE ESTIMATES

In accordance with applicable Canadian securities regulatory requirements, all mineral reserve and mineral resource estimates of the Company disclosed or incorporated by reference in this press release have been prepared in accordance with NI 43-101 and are classified in accordance with the Canadian Institute of Mining, Metallurgy and Petroleum ("CIM") Definition Standards for Mineral Resources and Mineral Reserves, adopted by the CIM Council on May 10, 2014 (the "CIM Standards"). NI 43-101 is a rule developed by the Canadian Securities Administrators that establishes standards for all public disclosure an issuer makes of scientific and technical information concerning mineral projects. NI 43-101 differs significantly from the disclosure requirements of the Securities and Exchange Commission (the "SEC") generally applicable to U.S. companies. For example, the terms "mineral reserve", "proven mineral reserve", "probable mineral reserve", "mineral resource", "measured mineral resource", "indicated mineral resource" and "inferred mineral resource" are defined in NI 43-101. These definitions differ from the definitions in the disclosure requirements promulgated by the SEC. Accordingly, information contained in this press release may not be comparable to similar information made public by U.S. companies reporting pursuant to SEC disclosure requirements.

Mineral resources which are not mineral reserves do not have demonstrated economic viability. Pursuant to the CIM Standards, mineral resources have a higher degree of uncertainty than mineral reserves as to their existence as well as their economic and legal feasibility. Inferred mineral resources, when compared with measured or indicated mineral resources, have the least certainty as to their existence, and it cannot be assumed that all or any part of an inferred mineral resource will be upgraded to an indicated or measured mineral resource as a result of continued exploration. Pursuant to NI 43-101, inferred mineral resources may not form the basis of any economic analysis. Accordingly, readers are cautioned not to assume that all or any part of a mineral resource exists, will ever be converted into a mineral reserve, or is or will ever be economically or legally mineable or recovered.

Further Consolidation of Cortadera

(NewsDirect)

Cortadera Porphyry Footprint Continues to Expand

· Hot Chili has succeeded in securing several new prospective mining rights, adjacent to mining rights in the recently announced transaction with Antofagasta Minerals S.A. (AMSA)

** Copper Equivalent (CuEq) reported for the drillhole 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=3.00 USD/lb, Au=1,700 USD/oz, Mo=14 USD/lb, and Ag=20 USD/oz. The entirety of the intersection is assumed as fresh. The recovery and copper equivalent formula for Cortadera – Recoveries of 83% Cu, 56% Au, 83% Mo and 37% Ag. CuEq(%) = Cu(%) + 0.56 x Au(g/t) + 0.00046 x Mo(ppm) + 0.0043 x Ag(g/t)

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.

Figure 1. Location of new mining rights(AMSA) relating to Cortadera, Productora, San Antonio, Valentina and nearby coastal range infrastructure of Hot Chili's combined Costa Fuego copper-gold project, located 600km north of Santiago in Chile.

* Copper Equivalent (CuEq) reported for the resource 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 CuEq calculation were: Cu=3.00 USD/lb, Au=1,700 USD/oz, Mo=14 USD/lb, and Ag=20 USD/oz. Metallurgical recovery averages for each deposit consider Indicated + Inferred material and are weighted to combine sulphide flotation and oxide leaching performance. The recovery and copper equivalent formula for each deposit is:

Cortadera and San Antonio – Weighted recoveries of 82% Cu, 55% Au, 82% Mo and 37% Ag.

CuEq(%) = Cu(%) + 0.56 x Au(g/t) + 0.00046 x Mo(ppm) + 0.0043 x Ag(g/t)

Productora – Weighted recoveries of 84% Cu, 47% Au, 47% Mo and 0% Ag (not reported)

CuEq(%) = Cu(%) + 0.46 x Au(g/t) + 0.00026 x Mo(ppm)

Costa Fuego – Weighted recoveries of 83% Cu, 53% Au, 69% Mo and 23% Ag

CuEq(%) = Cu(%) + 0.52 x Au(g/t) + 0.00039 x Mo(ppm) + 0.0027 x Ag(g/t)

** Reported on a 100% Basis - combining Mineral Resource Estimates for the Cortadera, Productora and San Antonio deposits. Figures are rounded, reported to appropriate significant figures, and reported in accordance with the JORC Code, CIM and NI 43-101. Metal rounded to nearest thousand, or if less, to the nearest hundred.

Total Resource reported at +0.21% CuEq for open pit and +0.30% CuEq for underground.
