610m at 0.5% CuEq including 138m at 0.8% CuEq

ASX Announcement

Friday 1st October 2021
Highlights
  • Hot Chili has recorded another strong extensional result at the Cortadera copper-gold porphyry discovery in Chile, further expanding the high grade resource (+0.7% CuEq) across the northern flank (North Flank) of the main porphyry (Cuerpo 3)
  • CRP0134D returned an extensive intersection of 610m grading 0.5% CuEq (0.4% copper (Cu), 0.1g/t gold (Au)) from 216m depth down-hole, including 138m grading 0.8% CuEq (0.6% Cu, 0.1g/t Au) from 634m depth
  • Results from CRP0134D and those recently reported from CRP0124D (362m grading 0.6% CuEq, including 82m grading 1.0% CuEq) have extended the North Flank by approximately 170m
  • The Northern Flank of Cuerpo 3 remains open with another 80m step-out diamond drill hole underway (CRP0155D, currently at 490m depth and in mineralisation)
  • Results pending for five drill holes from Cuerpo 2 which have visually recorded wide intersections of mineralisation from surface
  • Three drill rigs in operation, 4,946m of assay results pending from 20 drill holes, assay turnaround currently 44 days

* 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=1,550 USD/oz, Mo=12 USD/lb, and Ag=18 USD/oz.  Average Metallurgical Recoveries used were: Cu=83%, Au=56%, Mo=82%, and Ag=37%

Hot Chili Limited (ASX: HCH) (OTCQB: HHLKF) (“Hot Chili” or “Company”) is pleased to announce that recent drill results from its Cortadera copper-gold discovery in Chile continue to demonstrate strong resource growth.

Hot Chili’s Resource Development Manager Kirsty Sheerin said the expansion of the main porphyry was very pleasing ahead of the Company’s plans to up-grade the maiden 451Mt Cortadera resource.

“The North Flank of the high grade core to the main porphyry has continued to be a significant resource addition.

“We have added approximately 170m of width to Cuerpo 3 and hope to extend several other open flanks to the high grade core by year-end.

“We are also continuing to see positive shallow intersections in the current RC drilling program at Cuerpo 2.

“The next resource upgrade at Cortadera will provide a strong basis for the first combined open pit and block cave mining reserve estimate at our growing Costa Fuego copper-gold development.”

Cuerpo 3 North Flank Confirmed as Extensive High Grade Addition

Continued strong results have been reported from extensional resource drilling across the North Flank to the high grade core of the main porphyry (Cuerpo 3) at Cortadera.

CRP0134D returned an extensive intersection of 610m grading 0.5% CuEq (0.4% copper (Cu), 0.1g/t gold (Au)) from 216m depth down-hole, including 138m grading 0.8% CuEq (0.6% Cu, 0.1g/t Au) from 634m depth.

Importantly, the high grade results in CRP0134D were recorded at approximately the same vertical depth and lateral to CRP0124D, which recorded 82m grading 1.0% CuEq (0.7% Cu and 0.3g/t Au) within a broader intersection of 362m grading 0.6% CuEq (0.5% Cu, 0.2g/t Au) from 634m depth.

This recent drilling has demonstrated strong continuity of high grade (+0.7% CuEq) mineralisation and extended the North Flank by approximately 170m. 

A follow-up hole (CRP0155D) is currently underway to extend the North Flank by a further 80m.  CRP0155D is currently at 490m depth and is in mineralisation.

Figures 2 to 6 display the location of these new significant drilling intersections at Cortadera.

Expansion of Shallow Resources at Cortadera

Initial results have been returned for 5 shallow Reverse Circulation (RC) drill holes at Cuerpo 2. The results have extended the boundary of the resource across the southern, eastern and north eastern flanks of Cuerpo 2.

 In addition, CRP0139 was drilled in an up-dip position over the Cuerpo 2 resource and has recorded a 42m intersection grading 0.5% CuEq (0.4% Cu, 0.3g/t Au) from 180m depth to end-of-hole, within a broader 222m zone grading 0.3% CuEq (0.2% Cu, 0.1g/t Au) from surface. The result of CRP0139 has shown an upgrade in both copper and gold from the maiden resource model in this area.

Assay results are pending for a further five drill holes which have recorded wide zones of oxide and sulphide mineralisation from surface.  Additional RC drilling is continuing in this area to determine the potential for this shallow mineralisation to extend further.

Momentum Building Ahead of Canadian TSXV Dual-Listing

Hot Chili is currently the only major copper-gold developer in the America’s that is not listed in Canada. 

The Company’s low-altitude Costa Fuego copper-gold development in Chile is expected to compare favourably to leading copper-gold developers in Canada, which currently trade at many multiples of Hot Chili’s market capitalisation.

The Company plans to continue building momentum with its activities and newsflow ahead of its dual listing on the TSXV in Q4 this year, with several updates expected from ongoing drilling, exploration and development workstreams.

Hot Chili is operating five shifts of drilling per day with three drill rigs at Cortadera.  In addition, a fourth drill rig is being sourced to commence drill testing several large-scale growth targets (Productora Central and Santiago Z – See ASX announcement dated 17th September).

Following its dual listing in Canada, Hot Chili aims to release a major resource upgrade from Cortadera followed by the completion of a combined Pre-feasibility study.  These two major milestones will lay the foundation for the Company’s transformation into a major copper-gold producer in the coming years.

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

Table 1 New Significant DD & RC Drill Results at Cortadera

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.
CuEq % = Cu grade (%) + (0.5083x Au grade(g/t)) +0.0039x Ag grade(g/t)) + 0.0004x Mo grade(ppm))
