LOCATION, Jan. 23, 2024 /CNW/ - Hot Chili Ltd. (ASX: HCH) (TSXV: HCH) (OTCQX: HHLKF) ("Hot Chili" or the "Company") is pleased to announce the commencement of the next phase of the Company's 30,000m resource growth focused drill programme for the Costa Fuego Copper-Gold Project ("Costa Fuego" or "the Project"), located in the coastal range of the Atacama Region, Chile.
A total of 47 Reverse Circulation (RC) drill holes for 11,500m have been completed since the Company's resource growth focused drill programme commenced in late July 2023.
Drilling aims to test multiple resource growth opportunities, which may allow Hot Chili to consider an up-lift in the Pre-feasibility study scale for Costa Fuego.
The first phase of drilling in H2 2023 focused on resource extensional potential at Cortadera and first-pass drilling across new satellite targets. In addition, several RC pre-collars were drilled in preparation for the second phase of diamond drill testing in 2024 adjacent to the Company's two principal mineral resources: Cortadera; and Productora.
The second phase of drilling commenced on 12th January with one diamond drill rig operating on a 24-hour basis (double-shift). A programme of 10 diamond (DD) drill holes for approximately 5,000m is initially planned. The initial diamond drill programme comprises:
- Five DD holes planned to test four large-scale targets at Cortadera (refer to Figures 2 and 3). The first DD hole is currently testing a large co-incident conductivity and chargeability geophysical anomaly located north of Cortadera.
- A further five DD holes are planned to test three large-scale targets adjacent to Productora (refer to Figures 2 and 4)
The Company looks forward to providing further updates as DD drilling advances across these targets over the coming months.
Assay results have been received for first-pass drilling undertaken in late 2023 across three new satellite targets within the Costa Fuego landholding: Marsellesa, Cordillera and Corroteo.
Both Marsellesa and Cordillera are located approximately 10km southwest of Costa Fuego's planned central processing hub at Productora, and Corroteo is located approximately 5km southeast of Cortadera (refer to Figures 1 and 2).
A total of 4 RC drill holes for 1,244m were completed across the historical Marsellesa open pit copper mine footprint (refer to Figure 5). Significant intersections were recorded in each of the four drill holes:
- 25m grading 0.4% Copper (Cu) from surface including 10m grading 0.8% Cu from 7m depth
- 16m grading 0.5% Cu from 197m depth downhole including 6m grading 1.1% Cu from 198m depth
- 19m grading 0.5% Cu from 195m depth downhole including 2m grading 2.2% Cu from 195m depth
- 8m grading 0.8% Cu from 1m depth downhole including 4m grading 1.0% Cu from 4m depth
Higher grade copper drilling intersections are associated with both copper oxide (Cu bearing limonite, brochantite and chrysocolla) and copper sulphide (chalcopyrite) mineralisation localised within moderately east-dipping manto horizons (refer to Figure 5). Follow-up work is being planned to further assess mineralisation continuity across the 500m of prospective strike length.
The Marsellesa mine area is laterally extensive, measuring 400m in length and 200m in width, with historical open pit and underground mine workings exposing multiple zones of shallowly-dipping, strata-bound (manto-style), copper mineralisation.
A total of 6 RC drill holes for 1,450m were completed across the historical Cordillera copper mine footprint, located approximately 1km west of Marsellesa (refer to Figure 6). Significant intersections recorded, include:
- 93m grading 0.3% Cu from surface including 14m grading 0.4% Cu from surface
- 53m grading 0.3% Cu from 19m depth including 10m grading 0.4% Cu from 44m depth
- 184m grading 0.2% Cu from surface including 14m grading 0.3% Cu from 42m depth
Wide RC drilling intersections returned at Cordillera relate to broad zones of oxide (Cu bearing limonite with very minor cuprite) and sulphide (chalcopyrite, molybdenite) porphyry copper mineralisation confirmed below and surrounding the small surface mine workings.
Porphyry copper mineralisation with well-developed stockwork and sheeted A and B style porphyry veining is exposed in the Cordillera open pit mine workings, and porphyry outcrop has been mapped across an area measuring 300m in length and 200m in width.
A total of 8 RC drill holes for 2,324m was completed across the greenfield Corroteo exploration target located 5km southeast of Cortadera (refer to Figure 7). No significant intersections were recorded.
Wide spaced RC drilling has tested approximately 1.8km strike extent of the large-scale Corroteo alteration footprint. Significant pyrite mineralisation was encountered in drilling toward the northern extent of the target area extending under a wide alluvial gravel plain. Final drilling directed under this alluvial cover confirmed the presence of tonalitic porphyry.
Hot Chili's exploration team is currently assessing the new drill results on each of these satellite exploration targets in preparation for potential follow-up drilling and exploration work programmes.
The Company is in the final stages of completing an upgrade to its mineral resource for Costa Fuego based on all drilling completed since February 2022. The resource upgrade is expected to be released in Q1 2024.
The Company also looks forward to providing further updates on development study and water supply concept study advances this quarter.

| Notes to Table 1: Significant intercepts are calculated above a nominal cut-off grade of 0.1% Cu. Where appropriate, significant intersections may contain up to 30m down-hole distance of internal dilution (less than 0.1% Cu). Significant intersections are separated where internal dilution is greater than 30m down-hole distance. The selection of 0.1% Cu for intersection cut-off grade above is selected on the basis of exploration significance and is not meant to represent potential 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. |

Costa Fuego Combined Mineral Resource (Effective Date 31st March 2022)
| 1 Mineral Resources are reported on a 100% Basis - combining Mineral Resource estimates for the Cortadera, Productora and San Antonio deposits. All figures are rounded, reported to appropriate significant figures, and reported in accordance with the Joint Ore Reserves Committee Code (2012) and the Canadian Institute of Mining, Metallurgy and Petroleum (CIM) Standards on Mineral Resources and Reserves, Definitions and Guidelines prepared by the CIM Standing Committee on Reserve Definition, as required by National Instrument 43-101. |
| 2 The Productora deposit is 100% owned by Chilean incorporated company Sociedad Minera El Aguila SpA (SMEA). SMEA is a joint venture (JV) company - 80% owned by Sociedad Minera El Corazón Limitada (a 100% subsidiary of Hot Chili Ltd.), and 20% owned by CMP (Compañía Minera del Pacífico S.A (CMP)). |
| 3. The Cortadera deposit is controlled by a Chilean incorporated company Sociedad Minera La Frontera SpA (Frontera). Frontera is a subsidiary company - 100% owned by Sociedad Minera El Corazón Limitada, which is a 100% subsidiary of Hot Chili Ltd.. |
| 4 The San Antonio deposit is controlled through Frontera (100% owned by Sociedad Minera El Corazón Limitada, which is a 100% subsidiary of Hot Chili Ltd.) and has an Option Agreement with a private party to earn a 100% interest. |
| 5 The Mineral Resource estimates in the tables above form coherent bodies of mineralisation that are considered amenable to a combination of open pit and underground extraction methods based on the following parameters: Base Case Metal Prices: Copper US$ 3.00/lb, Gold US$ 1,700/oz, Molybdenum US$ 14/lb, and Silver US$20/oz. |
| 6 Metallurgical recovery averages for each deposit consider Indicated + Inferred material and are weighted to combine sulphide flotation and oxide leaching performance. Process recoveries: 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 - 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). |
| 7 Resource Copper Equivalent (CuEq) grades are calculated based on the 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 base case cut-off grade for mineral resources considered amenable to open pit extraction methods at the Cortadera, Productora and San Antonio deposits is 0.21% CuEq while the cut-off grade for mineral resources considered amenable to underground extraction methods at the Cortadera deposit is 0.3% CuEq. |
| 8 Mineral resources are not mineral reserves and do not have demonstrated economic viability. These Mineral Resource estimates include Inferred Mineral Resources that are considered too speculative geologically to have economic considerations applied to them that would enable them to be categorised as Mineral Reserves. It is reasonably expected that the majority of Inferred mineral resources could be upgraded to Measured or Indicated Mineral Resources with continued exploration. |
| 9 The effective date of the estimate of Mineral Resources is March 31st, 2022. Refer to ASX Announcement "Hot Chili Delivers Next Level of Growth" ("Resource Announcement") for JORC Code Table 1 information related to the Costa Fuego Resource Estimate (MRE) by Competent Person Elizabeth Haren, constituting the MREs of Cortadera, Productora and San Antonio (which combine to form Costa Fuego). Hot Chili confirms it is not aware of any new information or data that materially affects the information included in the Resource Announcement and all material assumptions and technical parameters stated for the Mineral Resource Estimates in the Resource Announcement continue to apply and have not materially changed. |
| 10 Hot Chili Ltd. is not aware of political, environmental or other risks that could materially affect the potential development of the Mineral Resources. |
