High Grade Copper-Gold Core Growing Rapidly at Cortadera
Results Expected Shortly
Hot Chili Limited (ASX code HCH) (“Hot Chili” or “Company”) is pleased to announce that diamond drilling is providing strong encouragement for continued growth of the high grade copper-gold core at the Company’s Cortadera discovery in Chile.
Strongly mineralised porphyry has been observed over a broad 220m zone in recently completed drill hole CRP0016D.
CRP0016D – a 350m diamond tail – was designed to test the potential for a significant up-dip extension to the southern flank of the high grade copper-gold core.
Results from CRP0016D are being prioritised for analysis and are expected to be reported within the coming fortnight.
Diamond drill hole CRP0042D recorded approximately 330m of mineralised porphyry. The hole was terminated early (in mineralisation) owing to significant deviation from its intended target and will be re-entered for a wedge hole at a later date.
Hot Chili has just commenced its third diamond drill hole (CRP0043D), designed to test a major up-dip extension to the northern flank of the high grade copper-gold core.
Resource workstreams remain on-track for delivering first resource estimates at Cortadera and then San Antonio in late July.
The Company will carefully assess the potential implications of these new drill holes on the forthcoming resource estimate for Cortadera. The maiden resource estimate, currently in preparation, incorporates all previous drilling.
The current drilling programme is initially focussed on growth of high grade copper and gold within the 2.3km discovery zone and aims to facilitate a second resource estimate for Cortadera.

The Company looks forward to releasing drilling results from CRP0016D and CRP0042D once all assays are received.
This announcement is authorised by the Board of Directors for release to ASX.

Note the location of the inset plan area for Cuerpo3 associated with the following figures. Note the HCH drilling intersection (Red) and historical drilling intersections (white).
Figure 2 Plan view of Cuerpo 3 – the Main porphyry of the four porphyry centres discovered to date at Cortadera. Note the growing extent of the modelled higher grade copper zone (majenta wireframe – +0.4% Cu) and the location of open boundaries for growth of the bulk copper envelope at Cortadera (yellow wireframe – +0.1% Cu).

Figure 4 Type Section A displaying HCH DD extensional drill results and recent 3D modelling of copper distribution at Cortadera. The section lies in the centre of Cuerpo 3. Note the location of hole CRP0016D in relation to the modelled high grade zone.
Figure 5 Type Section B displaying HCH DD drill results and recent 3D modelling of copper distribution at Cortadera. The section lies along the southeastern extent of Cuerpo 3 and displays the recently abandoned diamond hole CRP0042D which ended in mineralised porphyry. Note the location of where CRP0042D was meant to extend. This hole deviated significantly in its azimuth and is planned to be re-entered and navi/wedge drilled at a later date.
Cortadera is a privately-owned, major copper-gold porphyry discovery located 600km north of Santiago along the Chilean coastal range, where historical world-class discovery drill results were only publicly released by Hot Chili in February 2019.
Importantly, Cortadera lies 14km from the Company’s large-scale Productora copper development and adjacent to the high grade El Fuego satellite copper projects, as displayed in Figure 1 below.

On 22 February 2019, Hot Chili announced the execution of a formal Option Agreement to acquire a 100% interest in Cortadera. In early April, the Company commenced a confirmation drilling programme comprising 17 holes.
The drilling has confirmed and extended areas of surface enrichment and wide, higher-grade, copper-gold sulphide mineralisation at depth, which had not previously been closed off by 23,000m of historical diamond drilling.
Hot Chili’s recent drill holes at Cuerpo 3 (the largest of the four porphyries discovered to date) include some of the worlds’ stand-out copper-gold porphyry drill results reported in recent time. The Cuerpo 3 porphyry remains open to the north, south and at depth. Significant intersections include:
- 972m grading 0.5% copper and 0.2g/t gold from surface (including 412m grading 0.7% copper and 0.3g/t gold)
- 750m grading 0.6% copper and 0.2g/t gold from 204m down-hole depth (including 188m grading 0.9% copper and 0.4g/t gold)
- 848m grading 0.4% copper and 0.2g/t gold from 112m down-hole depth (including 184m grading 0.7% copper and 0.3g/t gold)
- 864m grading 0.4% copper and 0.1g/t gold from 62m down-hole depth (including 348m grading 0.6% copper and 0.2g/t gold),
- 649m grading 0.4% copper and 0.1g/t gold from 328m down-hole depth (including 440m grading 0.5% copper and 0.2g/t gold),
- 596m grading 0.5% copper and 0.2g/t gold from 328m down-hole depth (including 184m grading 0.7% copper and 0.3g/t gold), and
- 542m grading 0.5% copper and 0.2g/t gold from 422m down-hole depth, (including 218m grading 0.7% copper and 0.2g/t gold)

Source- Regulus Resources (TSXV. REG) November 2019 Corporate Presentation (slide 10) as per SNL financial, SNL search criteria include: >450 m interval, primarily copper interval & reported after Jan 1, 2018. Only longest reported interval considered. Results ordered by down-hole width of drill intersection and addition of CRP0029D and CRP0040D result.
Cortadera is shaping up as a globally significant standalone copper-gold project which can utilise the Productora project resources, and leverage from a central processing and combined infrastructure approach along the coastline of Chile.
The Company’s recent discovery and definition of a higher grade bulk tonnage underground development opportunity in combination with shallow, high grade bulk tonnage open pit sources – places Cortadera in a unique position amongst potential large-scale global copper-gold developments.
