Hot Chili Limited (ASX: HCH) (TSXV:HCH) (OTCQX: HHLKF) ("Hot Chili" or the "Company") is pleased to announce encouraging drill results that confirm the potential for further resource growth at the Cortadera copper-gold resource, the centrepiece of the Company’s low-altitude, Costa Fuego copper- gold project in Chile.
Highlights
CRP0201D (390m depth downhole, located below Cuerpo 1 resource extent) intersecting 2% chalcopyrite-pyrite sulphide mineralisation and porphyry B-veining within strongly biotite altered hornfels, assay results pending.
Cortadera’s Mineral Resource comprises three porphyry centres, which extend from surface over a strike extent of 2.3km. Cortadera’s two eastern porphyries have been defined to vertical depths up to 1.3km, however, drilling across the western-most porphyry (Cuerpo 1) had previously not intersected higher grade mineralisation (+0.3% CuEq) below 220m depth prior to 2023’s drill programme.
New drill results now confirm that higher grade mineralisation (+0.3% CuEq) extends and remains open at depth below Cuerpo 1 ahead of a planned Mineral Resource update for the second half of 2023.
New Results Confirm Extension to Mineralisation at Cuerpo 1
In 2022, the Company recorded an end-of-hole drill result (CORMET001, 6m grading 0.6% Cu from 354m depth) from a development study geotechnical drill hole (see Announcement released 29th April 2022) located below the Mineral Resource envelope for Cuerpo 1.
Over the past two months, the Company has extended diamond drill hole CORMET001, and completed a further five drill holes below Cuerpo 1. Initial assay results confirm a significant extension to mineralisation below the current Mineral Resource, intersecting mineralised porphyry (early- and intra-mineral) up to 300m below the Indicated Mineral Resource for Cuerpo 1.
Complete results have been received for three of six holes completed, and only partial results for two diamond holes (CRP0201D and CRP0202D) and one reverse circulation RC hole (CRP0203). Significant intersections recorded to date include:
1Partial result reported, currently awaiting assays for remaining intervals.
2Note that this intersection includes an interval from 336m to 350m previously reported in April 2022.
The Company looks forward to the return of the remaining drillholes from this program in the coming weeks.
Drilling CRP0201D from the Cortadera core yard, targeting Cuerpo 1 extension at depth February 2023 (results pending)
First-Pass Drilling Completed Across Western Cortadera (AMSA Landholding)
A first-pass drill programme, comprising sixteen RC drill holes for 4,116m, is complete across three porphyry targets within the recently secured AMSA landholding (see announcement dated 13th January 2023). These holes are located along the western extent of the Cortadera copper-gold Mineral Resource and results for fifteen of the sixteen holes are pending.
Drilling was primarily shallow (less than 300m depth) and focussed on defining the extent of Cortadera’s fourth porphyry (Cuerpo 4).
The Company confirmed significant copper mineralization associated with Cuerpo 4 in February with first results from diamond hole LCD001 (see announcement dated 23rd February 2023), which recorded 120m grading 0.5% CuEq* (0.4% Cu, 0.2g/t Au from 22m depth down-hole to end of hole. Importantly, this wide intersection also included 38m grading 1.0% CuEq* (0.8% Cu, 0.4g/t Au) from 22m depth, or 18m grading 1.3% CuEq* (1.0% Cu, 0.5g/t Au) from 32m depth.
Once all assay results have been received and reviewed, the Company and Antofagasta Minerals (AMSA) will plan a second-pass drill programme to follow-up the initial results of this programme as part of the 6,000m drill commitment to the option agreement (see announcement dated 28th November 2022).
The Company looks forward to receiving further results in the coming weeks.

Hot Chili Limited (ASX: HCH) (TSXV:HCH) (OTCQX: HHLKF) ("Hot Chili" or "Company") is pleased to announcefurther consolidation of the Cortadera copper-gold discovery in Chile.
The Company has succeeded in securing several new prospective mining rights at a recently held, government-run, public auction for the Huasco region of Chile. The new mining rights are located alongside mining rights of the recently announced (25 th November 2022) transaction with Antofagasta Minerals S.A. (AMSA).
Together, these new landholdings consolidate the western extension of Cortadera and allow Hot Chili to test a potentially much larger copper porphyry cluster.
Hot Chili has now secured four new large porphyry targets adjacent to the existing Cortadera resource (Cuerpo 1, 2 and 3), and added significant prospective strike length across two mineralised trends:
· Las Canas trend (+1.8km, N-S) - Three large porphyry targets including the Cuerpo 4 porphyry target (700m in strike length by 300m in width and drill confirmed, see announcement dated 25 th November 2022 for details of AMSA transaction)
· Cortadera trend (+1.1km, NW-SE) – One large porphyry target located directly along-strike from Cortadera on the Serrano fault, an important mineralising fault corridor connecting the Cortadera and Productora copper-gold deposits
The new landholding successfully acquired at auction contains the Cortadera trend extension and comprises seven mining rights covering 757 hectares. Three mining rights (Falla Maipo 2, 3, 4) were acquired for US$110,000 and the remaining four mining rights (CF 6, 7, 8, 9) were successfully awarded following forfeiture of overlapping third party mining rights.
Figures on the following pages outline the location of the new mining rights in relation to Cortadera.
Drilling across the western extension to Cortadera is planned to commence as soon as possible.
This recent strategic consolidation of the Cortadera porphyry deposit area has the potential to deliver another significant leg of resource growth to the Costa Fuego copper hub.
Further updates and announcements are expected in the lead-up to drill commencement.

Hot Chili Limited (ASX: HCH) (TSXV:HCH) (OTCQX: HHLKF) ("Hot Chili" or "Company") is pleased to provide details of a material transaction with Chilean copper major Antofagasta Minerals S.A. (AMSA).
Hot Chili has executed an Option Agreement enabling Hot Chili to acquire a 100% interest in AMSA's mining rights adjoining the western margin of Hot Chili's Cortadera copper-gold porphyry discovery, the centre-piece of the Company's Costa Fuego senior copper development in Chile.
This strategic option agreement consolidates the highly prospective AMSA mining rights, containing near-surface drill intersections of copper-gold porphyry mineralisation, with Hot Chili's contiguous Cortadera project.
Cortadera has been the growth engine for Hot Chili since the Company executed a transaction to acquire the project in 2019.
Cortadera's current Indicated resource of 471Mt grading 0.46% CuEq for 1.7Mt copper and 1.8Moz gold and Inferred resource of 108Mt grading 0.35% CuEq for an additional 0.3Mt copper and 0.3Moz gold (ASX announcement dated 31 st March 2022) is contained within three porphyry centres, trending NW-SE, over a strike extent of 2.3km.
The option enables the consolidation of Cortadera and near doubles the prospective strike length of the discovery, increasing the near term, material resource growth potential for Hot Chili.
AMSA's five mining rights cover 517 hectares and contain a large outcropping mineralised porphyry (Cuerpo 4 - 700m in strike length by 300m in width) with similar dimensions to Cortadera's main porphyry (Cuerpo 3) as well as other identified porphyry targets, trending N-S, over a prospective strike extent of approximately 1.8km.
In 2005, AMSA intersected significant copper-gold-molybdenum mineralisation at Cuerpo 4, with five shallow Reverse Circulation (RC) drill holes totalling 1,056m (Drilling data and associated drilling intersections not previously publicly reported, AMSA internal report, see JORC Code Table 1 in this announcement for further details).
Four of AMSA's five drill holes recorded wide intersections of mineralisation, including COR-03 which recorded 128m grading 0.5% CuEq (0.4% Cu & 0.1g/t Au) from 28m downhole depth, including 16m grading 1.3% CuEq (1% Cu & 0.5g/t Au) from 28m.
The historical drilling across Cuerpo 4 clearly demonstrates open pit resource growth potential, given the shallow nature of copper-gold-molybdenum mineralisation, and near-surface, copper-gold enrichment.
Next Steps – Rapid Resource Definition
A first-pass drilling programme comprising 16 holes for 6,000m is expected to start as soon as possible.
Drilling will test Cuerpo 4 and two other targets within AMSA's landholding using RC and Diamond (DD) drilling. Hot Chili and AMSA have agreed on the detail and staging of the planned drilling programme after a collaborative and detailed geological review by both companies' technical teams.
Drilling is also planned across Hot Chili's Cortadera North target, where earlier exploration drilling targeting a large surface molybdenum anomaly in 2020 intersected wide zones of silver mineralisation. This work vectored towards a sizeable copper-gold porphyry target (Cuerpo 4) on AMSA's adjacent mining right.
Hot Chili then ceased all exploration activities at Cortadera North until an agreement could be entered into with AMSA to enable Hot Chili to acquire the adjacent landholding.
Revision to Costa Fuego Growth and Development Timetable
The transaction provides the next step in Hot Chili's long term growth strategy. The AMSA mining rights provide relatively low cost and highly accretive resource growth potential due to their proximity to the Company's Cortadera open pit resource base.
Hot Chili's next resource update, which was proposed to be delivered in late 2022, is now expected to be finalised in H2 2023 to include the proposed drilling on the AMSA mining rights.
The combined Pre-feasibility Study (PFS) for Costa Fuego, studying targeted annual production rates of up to 100kt Cu and up to 70koz Au for a +20 year life of mine, will be paused until the Company can assess the impact of resource growth potential at Cortadera. The Company's decision to pivot the PFS ensures that future expenditure relating to the PFS can be optimised for infrastructure location and a potentially larger scale copper operation.
Only critical PFS workstreams will be continued to secure long-lead time items (environmental and social) and key value additions (metallurgical) to ensure Costa Fuego remains on-track to potentially be delivered into production in 2028.
A Preliminary Economic Assessment( PEA) of the combined Costa Fuego project at the current 20Mtpa sulphide concentrator study scale is now planned to be delivered in H1 2023.
Hot Chili aims to ensure that Costa Fuego's "clean and green" attributes, including low elevation/coastal location, proximity to existing infrastructure, access to renewable power, use of seawater for processing and a central processing strategy, can be leveraged with this consolidation and growth opportunity.
Costa Fuego remains one of a few front-runner, large copper development projects in the world that can be advanced to production in a timely manner due to Hot Chili's consolidation, development and permitting efforts over the last decade.
Recent positive developments in Chile's constitutional process and taxation review have reaffirmed Chile's stable and attractive standing as a top global mining investment jurisdiction.
Option Agreement to Acquire 100% Interest in AMSA's Cortadera Mining Rights
Under an Option Agreement (Option) between Frontera SpA ("Frontera" - 100% subsidiary of Hot Chili) and Antofagasta Minerals SA (AMSA), Frontera has the option to acquire a 100% interest in the AMSA mining rights adjoining Cortadera within a two-year period on the following terms:
· Completion of 6,000m of drilling of any type, and
· Upon completion of the 6,000m drill commitment, Payment of a US$1.5 million Option exercise price to acquire the AMSA's mining rights, and
· Following exercise of the Option, AMSA has the right to buy-back a 55% interest in the AMSA mining rights within 120 days of exercise of the Option, by repaying 55% of the Option exercise price and paying five times the exploration expenditure incurred during the option period.
This transaction represents a strategic consolidation of the Cortadera porphyry deposit area and has the potential to deliver relatively low-cost, organic resource growth to the Costa Fuego copper hub.
Hot Chili plans to commence systematic exploration and resource definition drilling across this new landholding addition at Cortadera as soon as possible.
The Directors thank AMSA for their commitment to work with Hot Chili and to enable the continued consolidation of a globally significant, emerging copper hub for the Vallenar region of Chile.
This announcement is authorised by the Board of Directors for release to ASX and TSX.
* Copper Equivalent (CuEq) reported for the resource 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 × Cu_recovery).

For Cortadera and Productora, significant intersections 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 intersection widths are estimated to be at or around true-widths of mineralisation.

Osisko Metals’ high-quality polymetallic assets present a compelling investment opportunity amid a rapidly expanding critical and base metals market, as North America continues to strengthen its domestic supply.
Osisko Metals (TSXV:OM) is an exploration and development company focusing on two base metal assets in Canada – Gaspé Copper and Pine Point – targeting copper and zinc, both critical minerals necessary for the global transition to clean energy. These assets are past-producing, brownfield projects of significant potential for future production.
The Gaspé Copper project in Québec has a rapid development plan to begin mining the indicated resource of 495 million tons (Mt) of ore grading 0.37 percent copper equivalent. As the gap between available copper supply and growing demand widens, Osisko Metals is well-positioned to help create and strengthen a domestic supply chain for the North American market.
The company’s Pine Point zinc-lead project in the Northwest Territories contains an indicated mineral resource estimate of 49.5 million tons at 4.2 percent zinc and 1.5 percent lead, in addition to significant inferred resources. Zinc is a necessary mineral for the clean energy transition and has important applications throughout the manufacturing industry. This widespread use of this mineral has analysts cautioning about a looming supply shortage.
A preliminary economic assessment (PEA) completed in 2022 indicates the Pine Point project has the potential to become a world-class, high-grade zinc asset, with an after-tax net present value (NPV) of C$602 million and internal rate of return (IRR) of 25 percent.
In February 2023, Osisko Metals announced a C$100-million investment agreement with Appian Natural Resources Fund III for a joint venture on the Pine Point project. The agreement includes C$75.3 million of funding for the project and up to C$24.7 million in cash payments to Osisko Metals.
Led by a management team with a wide range of expertise throughout the natural resources industry and experience in geology, exploration, corporate finance and corporate administration, Osisko Metals is well-poised to become a world-class supplier of base metals.
The Gaspé Copper project in Québec is among the most significant copper development projects in eastern North America. Osisko Metals completed the100-percent acquisition of Gaspé Copper in July 2023 and has since commenced drilling at the property. Québec has a well-known reputation as one of the most mining-friendly jurisdictions in North America, with a long history of copper production.
The Pine Point asset in the Northwest Territories has the infrastructure in place to help the company move the project toward development. The project has an existing hydroelectric power substation on site, rail access within 60 kilometers, and paved access roads to the site.
