Cortadera Delivers Another Outstanding Intersection: 876m at 0.5% CuEq including 206m at 0.9% CuEq
Highlights
- Hot Chili has recorded another exceptional result at the Cortadera copper-gold porphyry discovery off the back of a major resource upgrade to its Costa Fuego copper hub in Chile
- An outstanding intersection of 876m1 grading 0.5% CuEq (0.4% copper (Cu), 0.1g/t gold (Au)) from 246m depth down-hole,including 206m2 grading 0.9% CuEq (0.7% Cu, 0.3g/t Au) from 414m depth was returned from drillhole CORMET006 (1excluding 18m unsampled and 2excluding 4m unsampled due to geotechnical test work)
- New drill result demonstrates strong continuity of high-grade resources (+0.6% Cu) at Cortadera ahead of the Costa Fuego Pre-Feasibility Study (PFS), forecast for release in Q3 2022
- CORMET006 is the first of five – development study diamond drill holes, already completed at Cortadera for hydrological and geotechnical modelling, a sixth diamond drill hole is planned
- The remaining four diamond drill holes already completed have visually recorded wide, strongly mineralised, intersections with assay results pending
- Three drill rigs in operation with an exploration update and first drill results from Productora expected shortly
* Copper Equivalent (CuEq) reported for the drill holes 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. Average Metallurgical Recoveries were: Cu=83%, Au=56%, Mo=82%, and Ag=37%.
Hot Chili Limited (ASX: HCH) (TSXV: HCH) (OTCQX: HHLKF) (“Hot Chili” or “Company”) is pleased to announce continuing strong results from its Cortadera porphyry discovery, the centrepiece of the company’s low-altitude, Costa Fuego senior copper development in Chile.
Five development study Diamond Drill (DD) holes, of a six-hole programme, have been completed at Cortadera this year in preparation of the Costa Fuego PFS, forecast for completion in Q3 2022.
Assay results returned from the first (CORMET006) of these five diamond drill holes have delivered an outstanding intersection of 876m1 grading 0.5% CuEq (0.4% copper (Cu), 0.1g/t gold (Au)) from 246m depth down-hole, including 206m2 grading 0.9% CuEq (0.7% Cu, 0.3g/t Au) from 414m depth (1excluding 18m unsampled and 2 excluding 4m unsampled due to geotechnical test work).
This latest significant drilling intersection from the main porphyry (Cuerpo 3) at Cortadera provides further confidence in the recently announced resource upgrade for Costa Fuego (see announcement dated 31st March 2022).
Costa Fuego’s High Grade (+0.6% CuEq) Indicated resources have grown by 53% and now account for over one third of contained copper and gold (previously 20%). High Grade Indicated resources stand at 156Mt grading 0.79% CuEq for 1.0Mt Cu, 0.85Moz Au, 2.9Moz Ag & 24kt Mo.
A significant component of the recently announced resource upgrade was driven by the definition of a large high grade core extending over 1 km vertically at Cuerpo 3.
Results from CORMET006 have confirmed the estimation of the Cuerpo 3 high grade core is robust, while also providing critical hydrological and geotechnical testwork for mining studies.
Two DD rigs are in operation (development drilling) and one Reverse Circulation (RC) drill rig is undertaking exploration drilling at Productora, located 14km from Cortadera.
The Company looks forward to pending assay results from remaining development study DD holes completed at Cortadera, having all visually recorded wide intersections of strong mineralisation.
Assay results being returned from exploration drilling at Productora are also expected to be released shortly.

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.

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%.

2 excluding 4m unsampled due to geotechnical test work
Significant intercepts are calculated above a nominal cut-off grade of 0.2% Cu. Where appropriate, significant intersections may contain up to 30m down-hole distance of internal dilution (less than 0.2% Cu). Significant intersections are separated where internal dilution is greater than 30m down-hole distance. The selection of 0.2% Cu for significant intersection cut-off grade is aligned with marginal economic cut-off grade for bulk tonnage 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 true-widths of mineralisation

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 Metallurgical Recoveries used were: Cu=83%, Au=56%, Mo=82%, and Ag=37%
