New copper (Cu) and silver (Ag) intersections from resource up-grade drilling of the high-grade San Antonio resource, part of the Company’s low-altitude, Costa Fuego senior copper development in Chile

· Highlights include:

o 21m grading 1.6% CuEq (1.6% Cu, 3.2g/t Ag) from 74m depth downhole

o 13m grading 1.3% CuEq (1.3% Cu, 3.2g/t Ag) from 133m depth downhole

including 2m grading 3.7% CuEq (3.5% Cu, 7.6g/t Ag)

o 7m grading 1.6% CuEq* (1.5% Cu, 4.8g/t Ag) from 11m depth downhole

including 2m grading 4.0% CuEq (3.9% Cu, 12.9g/t Ag)

o 4m grading 1.7% CuEq (1.7% Cu, 3.9g/t Ag) from 170m depth downhole

o 4m grading 1.6% CuEq (1.4% Cu, 6.4g/t Ag) from 115m depth downhole

· New results positively impact existing Inferred resource (4.2Mt grading 1.2% CuEq), which is set to be upgraded to Indicated classification in next Costa Fuego resource update, expected later this year

· Final drill results from the Valentina high grade copper-silver deposit expected shortly, regulatory application for follow-up drill programme being prepared

· Drilling continuing at Santiago Z porphyry exploration target - five drill holes complete, results pending

* Copper Equivalent (CuEq) reported for the drill holes at San Antonio used 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). 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. Average fresh rock metallurgical recoveries were Cu=88%, Au=72%, Mo=88%, and Ag=69%.

Hot Chili Limited (ASX: HCH) (TSXV: HCH) (OTCQX: HHLKF) (“Hot Chili” or “Company”) is pleased to announce new drill results from resource upgrade drilling across the high-grade San Antonio copper deposit, part of the Company’s Costa Fuego, coastal range, copper-gold hub in Chile.

Importantly, several drill holes recorded higher grades than estimated in the current San Antonio Inferred resource model.

The new drill results will upgrade the classification of the existing resource at San Antonio from Inferred to Indicated – allowing the resource to be included in open pit reserve estimates for the Costa Fuego Pre-feasibility Study (PFS).

A total of thirteen Reverse Circulation (RC) drill holes for 2,012m were complete across the San Antonio resource window to test extensional potential, as well as in-fill areas of lower geological confidence. Seven RC drill holes recoded significant intersections. In addition, three diamond holes for 495m were completed for metallurgical testwork purposes.

The current resource at San Antonio ((Inferred resource of 4.2Mt grading 1.2% CuEq (1.1% Cu, 2.1g/t Ag) for 48kt Cu and 287koz Ag, reported March 2022) extends from surface over a strike length of approximately 1km, and is amenable to open pit mining with relatively low strip-ratio.

Drilling undertaken across San Antonio, and its neighbouring high grade deposit Valentina, have provided significant encouragement for the addition of two potential high grade, front-end, open pit, ore sources for the combined Costa Fuego coastal copper super-hub.

SAPMET003 mineralisation in altered sandstone containing ~5% sulphides (pyrite and chalcopyrite) from 140m downhole which graded 3.7% CuEq (3.5% Cu, 7.6g/t Ag)

Expanded Drill Programme Planned for Valentina

Recent drill results from San Antonio’s neighbouring deposit Valentina recorded a number of outstanding shallow result, including 3m grading 12.1% CuEq (11.8% Cu & 52.6g/t Ag) within a broader drilling intersection of 12m grading 4.6% CuEq (4.5% Cu & 16.5g/t Ag) from 25m depth down-hole (VALMET0002 as reported on 24th August 2022).

High grade copper-silver mineralisation at Valentina is defined over 300m and is open along strike and at depth.

Importantly, these new high grade drill result recorded in VALMET002, which lie 120m south of the historical Valentina underground mine, remains open and untested to the south below a shallow cover sequence of gravels.

A regulatory clearing application is being prepared to facilitate follow-up drilling at Valentina, which will expand resource drill definition across this potentially high-impact future resource addition to Costa Fuego.

The Company looks forward to releasing final drill results from Valentina shortly as well as an update on first-pass drilling activities across the Santiago Z porphyry exploration target.

This announcement is authorised by the Board of Directors for release to ASX.

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 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. Refer to Announcement “Hot Chili Delivers Next Level of Growth” (31st March 2022) for JORC Table 1 information related to the Costa Fuego Mineral Resource estimates.

* 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). 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. For Cortadera and San Antonio (Inferred + Indicated), the average metallurgical recoveries were Cu=83%, Au=56%, Mo=82%, and Ag=37%. For Productora (Inferred + Indicated), the average metallurgical recoveries were Cu=83%, Au=43% and Mo=42%. For Costa Fuego (Inferred + Indicated), the average Metallurgical Recoveries were Cu=83%, Au=51%, Mo=67% and Ag=23%.

Significant intercepts are calculated above a nominal cut-off grade of 0.5% Cu, with a minimum estimated true thickness of 1.5m. These parameters are aligned with marginal economic cut-off grades for narrow, high-grade polymetallic copper deposits of similar grade in Chile and elsewhere in the world. Down-hole significant intercept widths are estimated to be at or around 70 per cent of true-widths of mineralisation

* Copper Equivalent (CuEq) reported for the drill holes at San Antonio used Costa Fuego averages (as no metallurgical testwork has been completed) 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). 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. Average fresh rock metallurgical recoveries were Cu=83%, Au=56%, Mo=82%, and Ag=37%.
