Next Phase of Copper-Gold Growth Begins
Drilling Underway Across Major Extension to Cortadera
Hot Chili Limited (ASX: HCH) (TSXV:HCH) (OTCQX: HHLKF) (“Hot Chili” or “Company”) is pleased to
announce that drilling has commenced across the recently secured western extension to the Cortadera
copper-gold discovery, the centrepiece of the Company’s low -altitude, Costa Fuego senior copper
development in Chile.
One diamond drill rig (oper ating on a double -shift basis) and one reverse circulation drill rig (operating on a
single-shift basis) are in operation, testing the potential for Cortadera to host a much larger copper porphyry
cluster than currently defined.
The initial programme, comprising approximately 10,000m of drilling, will test four porphyry targets (including
three targets on the recently optioned AMSA landholding) added to Cortadera through successful consolidation
efforts announced in late November 2022.
Importantly, Hot Chili has more than doubled the prospective strike length of the discovery from 2.3km to 5.2km
(as outlined in figure 3), increasing the near term, material resource growth potential for Hot Chili.
Cortadera’s current Indicated resource of 471Mt grading 0.46% CuEq for 1.7Mt copper and 1.8Moz gold and
Inferred resource of 108Mt grading 0.35% CuEq for an additional 0.3Mt copper and 0.3Moz gold (ASX
announcement dated 31st March 2022) is contained within three porphyry centres.
Both drill rigs are currently drilling Cortadera’s potential fourth porphyry (Cuerpo 4), where previous historical
drilling had intersected encouraging shallow copper-gold porphyry mineralisation, including COR-03 which
recorded 128m grading 0.5% CuEq (0.4% Cu & 0.1g/t Au) from 28m downhole depth, including 16m grading
1.3% CuEq (1% Cu & 0.5g/t Au) from 28m (as announced to ASX and TSXV on 28th November 2022).

The Company is well funded to complete its planned drilling and deliver its next set of key growth and
development milestones for Costa Fuego this year, including: a Preliminary Economic Assessment (PEA) in
H1; and a resource upgrade in H2.
This next growth phase provides an opportunity to optimise and potentially up-scale Costa Fuego’s future
annual metal production rates, currently being studied at up to 100kt Cu and up to 70koz Au for a +20-year life
of mine.
The Company plans to deliver Costa Fuego’s Pre-feasibility Study (PFS) in H1 2024 and remains on-track as
one of only a few near-term production projects in the world capable of producing +100 ktpa Cu in the next five
years, while also boasting low capital intensity and strong ESG credentials.
The Directors look forward to an exciting period of news flow and results from drilling activities at Cortadera
this year.
This announcement is authorised by the Board of Directors for release to ASX and TSX.

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 nea rest thousand, or if less, to the nearest
hundred.
Total Resource reported at +0.21% CuEq for open pit and +0.30% CuEq for underground.

magnetics image – blue is low, red is high) signature of the Cortadera deposit window in relation to A+B vein contours
and late stage porphyry dykes. Subtle de-magnetised anomalies along the main mineralising trends (Las Canas and
Cortadera) are of particular interest given the magnetic signatures of Cortadera’s three porphyry centres. See
