Hot Chili Announces Latest Drill Results for La Verde, Doubling Porphyry Discovery Footprint

Rhea-AI Summary

Hot Chili Limited (HHLKF) has reported significant expansion in its La Verde copper-gold discovery in Chile. The latest phase-one drilling results have doubled the discovery footprint to 1,000m by 750m, extending up to 400m vertical depth. Key findings include multiple higher-grade centers with notable intersections such as 389m grading 0.4% Cu and 0.1 g/t Au from 4m depth. The discovery, located 30km south of the Company's Costa Fuego Cu-Au Project, remains open laterally and at depth. Three distinct higher-grade centres have been identified: North-East, South-East, and South-West, with all zones remaining open for expansion. The Company is advancing regulatory applications for phase-two drilling, which will include both RC and diamond drilling to extend higher-grade centres at depth.

Positive

Potential for Significant Open Pit Mine Life Addition for Costa Fuego Cu-Au Hub

Further Development Study Updates Expected for Costa Fuego and Huasco Water

PERTH, Australia, May 20, 2025 /PRNewswire/ - Hot Chili Limited (ASX: HCH) (TSXV: HCH) (OTCQX: HHLKF) ("Hot Chili" or the "Company") is pleased to report a third round of strong assay results from its La Verde copper-gold (Cu-Au) discovery, located approximately 30km south of the Company's Costa Fuego Cu-Au Project ("Costa Fuego" or "the Project") planned central processing hub at low elevation in the coastal range of the Atacama region, Chile.

The Company concluded a phase-one drilling campaign across the La Verde Cu-Au porphyry discovery on 10 April 2025, with a total of 31 RC drill holes (9,600 m) completed to date.  Following a period of delayed laboratory turnaround time, final assay results have been received and compiled.

Initial assay results from the first 12 RC drill holes at La Verde confirmed a 400 m by 550 m discovery footprint, extending from near-surface to approximately 300 m vertical depth (refer to announcement dated 11 February 2025).

Recently returned assay results have now more than doubled the initial discovery footprint, resulting in an extensive +0.2% Cu mineralisation footprint of 1,000 m by 750 m extending up to 400 m vertical depth (Figures 2 and 5) and remaining open laterally and at depth.  

Importantly, multiple distinct higher-grade centres have been confirmed from near surface (Figures 2, 3 and 5).  Assessment of each of these higher-grade centres indicates:

1.  North-East (NE) Higher-Grade Centre

• Located approximately 180 m to the north-east of the historical shallow copper oxide open pit
• Higher-grade Cu-Au zone defined in six RC drill holes
• Current dimensions: 180 m strike by 280 m width by 320 m in vertical extent
• Remains open along strike to the north-east (beneath shallow gravel cover) and at depth

2.  South-east (SE) Higher-Grade Centre

• Located approximately 70 m to the south-east of the historical shallow copper oxide open pit
• High-grade Cu-Au zone defined by nine RC drill holes
• Current dimensions: 320 m strike by 340 m width by 400 m in vertical extent
• Remains open to the west beneath the open pit, to the east (beneath shallow gravel cover), and at depth

3.  South-west (SW) Higher-Grade Centre

• Located 310 m to the south of the historic open pit
• High grade Cu-Au zone defined by two RC drill holes
• Current dimensions: 90 m strike by 120 m width by 260 m in vertical extent
• Remains open to the south (beneath shallow gravel cover) and at depth

The extent of mineralisation beneath the existing La Verde open pit remains untested at this stage, due to limitations of RC drilling through clay altered structures. 

The Company is reviewing multi-element assay results to enhance understanding of the La Verde discovery, validate geological interpretations, and guide four-dimensional modelling and future drilling plans.

Three-dimensional magnetic inversion modelling has revealed a NNE-SSE trending weak magnetic anomaly aligned with the tonalitic porphyry intrusion (Figure 4). This relationship is guiding the evaluation of regional geophysical and geochemical assessments to identify extensions of the La Verde system and new porphyry targets within the broader magnetic destruction zone (Figure 6).

Regulatory applications for further drill access at La Verde are advancing, with phase-two drilling (RC and diamond drilling) planned to commence once approvals are received.

The Company looks forward to providing further updates, including advancements in exploration understanding of La Verde's growth potential, as well as various development study activities related to the current Pre-Feasibility Study optimisation phase for its Costa Fuego and Huasco Water projects.

Notes to Table 1: Significant intercepts for La Verde 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.

For previously released significant intercepts see announcement dated 18th December 2024 and 11th February 2025.
