LCD0001 (56m depth) grading 1.0% Cu, 0.7g/t Au, 4.6g/t Ag. Tonalitic porphyry with sericite-chlorite alteration and 2% A-B porphyry vein abundance. Confirmation drill hole across new fourth porphyry at Cortadera
Highlights First assay results returned from stage-one drilling across the recently consolidated western extension to the Company's Cortadera copper-gold porphyry resource in Chile New assay results confirm a fourth porphyry at Cortadera, returning a wide diamond drill intersection from shallow depth, similar in tenor to historical twin drill hole results recorded by Antofagasta Minerals SA in 2005 (see announcement dated 26th November 2022): o 120m grading 0.5% CuEq* (0.4% Cu, 0.2g/t Au) from 22m depth down-hole to end of hole; including 38m grading 1.0% CuEq* (0.8% Cu, 0.4g/t Au) from 22m depth; or including 18m grading 1.3% CuEq* (1.0% Cu, 0.5g/t Au) from 32m depth Wide intercept of mineralised porphyry intersected below Cortadera's Cuerpo 1 porphyry confirming significant resource expansion potential; assay results pending Drill programme expanded to test five new targets across Cortadera's larger porphyry cluster footprint with ten drill holes complete and a further fifteen drill holes remaining in stage-one Fully funded with cash balance of approximately A$10 million * Copper Equivalent (CuEq) reported for the drillhole intersections 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). The Metal Prices applied in the calculation were: Cu=3.00 USD/lb, Au=1,700 USD/oz, Mo=14 USD/lb, and Ag=20 USD/oz. The entirety of the intersection is assumed as fresh. The recovery and copper equivalent formula for Cortadera – Recoveries of 83% Cu, 56% Au, 83% Mo and 37% Ag. CuEq(%) = Cu(%) + 0.56 x Au(g/t) + 0.00046 x Mo(ppm) + 0.0043 x Ag(g/t) |
Hot Chili Limited (ASX: HCH) (TSXV:HCH) (OTCQX: HHLKF) (“Hot Chili” or“Company”) is pleased to announce first drill results from the recently secured western extension to the Cortadera copper-gold resource, the centrepiece of the Company's low-altitude, Costa Fuego copper-gold project in Chile.
New assay results have recorded a significant drill intersection of shallow copper-gold porphyry mineralisation, confirming the presence of a fourth porphyry (Cuerpo 4) at Cortadera.
Diamond drill hole LD0001 was drilled as a confirmatory twin hole to historical1 AMSA drill hole COR-03 that intersected 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 depth (as announced on 28th November 2022).
LCD0001 has successfully returned a similar result to AMSA's hole, intersecting 120m grading 0.5% CuEq* (0.4% Cu, 0.2g/t Au from 22m depth down-hole to end of hole. Importantly, the 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.
Sulphide mineralisation (chalcopyrite-pyrite) is primarily hosted within an early and intra-mineral stage tonalitic porphyry with sericite-chlorite-biotite alteration and 2 to 7% A-B porphyry vein abundance (typical of higher grade sulphide porphyry mineralisation at the Cortadera resource). Results for a further eight Reverse Circulation (RC) drill holes at Cuerpo 4 are pending.
The Company is also pleased to confirm potential for a significant depth extension to the current Mineral Resource (resource) below Cuerpo 1 at Cortadera.
Cuerpo 1 Resource Growth Potential Expanding
Diamond drill hole CORMET001 was completed to a depth of 350m in April 2022 and confirmed significant mineralisation below the defined limits of the Cuerpo 1 resource, with the hole ending in 6m grading 0.6% copper in mineralised porphyry (as announced 29th April 2022).
CORMET001 has now been extended to 611m depth and has recorded a 70m intersection of visually identified sulphides in mineralised porphyry between 350m and 420m depth down hole. Visually identified sulphide mineralisation comprised 1 to 3% chalcopyrite as disseminations and in association with pyrite and 2 to 10% A-B porphyry veining within early-stage and intra-mineral host porphyry.
Assay results are pending for CORMET001 and a further four drill holes have been added to drill test below the highest grade sulphide zone of Cuerpo 1, which remains open at depth for resource expansion.
First-Pass Drill Programme Expanded and Advancing
Five new porphyry targets are being tested as part of Hot Chili's first-pass 6,000m drill programme for 2023 following the inclusion of additional targets at Cortadera North and Cuerpo 1. These additional targets are located within Hot Chili's 100% landholdings and add to Cortadera's larger porphyry cluster potential.
Since drilling commenced on 11th January, a total of 10 drill holes for 3,300m have been completed and a further 15 drill holes for 2,700m remain.
A second-pass 4,000m drill programme is planned to commence following review of the first-pass programme drill results.
The current status of the drill programme is outlined on the below figures and as follows:
1. Cuerpo 4 (AMSA Option Agreement for 100% ownership)
9 drill holes complete (results pending for 8 drill holes), 2 drill holes planned
2. Target 2 (AMSA Option Agreement for 100% ownership)
1 drill hole planned
3. Target 3 (AMSA Option Agreement for 100% ownership)
3 drill holes planned
4. Cuerpo 1 Depth Extension (100% Hot Chili ownership)
1 drill hole complete (assay results pending), 4 drill holes planned (2 holes underway)
5. Cortadera North (100% Hot Chili ownership)
5 drill holes planned
Further assay results are expected over the coming weeks.
The Directors look forward to an exciting period of results from drilling activities at Cortadera this year.

Notes:
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.
CORMET001 has now been extended to 611m depth (from 350m depth) and has recorded a 70m intersection of visual sulphides in mineralised porphyry between 350m and 420m depth down hole. Visual sulphide mineralisation comprised 1 to 3% chalcopyrite as disseminations and in association with pyrite and 2 to 10% A-B veining within early-stage and intra-mineral host porphyry.
* Copper Equivalent (CuEq) reported for the drillhole intersections 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). The Metal Prices applied in the calculation were: Cu=3.00 USD/lb, Au=1,700 USD/oz, Mo=14 USD/lb, and Ag=20 USD/oz. The entirety of the intersection is assumed as fresh. The recovery and copper equivalent formula for Cortadera is: – Recoveries of 83% Cu, 56% Au, 83% Mo and 37% Ag. CuEq(%) = Cu(%) + 0.56 x Au(g/t) + 0.00046 x Mo(ppm) + 0.0043 x Ag(g/t)

About Hot Chili
Hot Chili Ltd (ASX/TSXV: HCH, OTCQX: HHLKF) aims to build shareholder value through the acquisition, exploration and development of high-quality copper assets in a low elevation and accessible region of northern Chile. With substantial mineral resources already defined, the Company's Costa Fuego Copper Hub is well positioned to benefit from the looming structural shortfall in copper production due to its size, quality and low economic hurdle location with an indicated resource of 2.8Mt Cu, 2.6Moz Au and 67kt of Mo (in 725Mt) and inferred resource of 0.6 Mt Cu, 1.2 Moz Au and 13kt Mo (in 202Mt). Costa Fuego is rated by S&P Global Market Intelligence one of the top 10“low risk” undeveloped copper projects globally. Hot Chili has materially de-risked the potential future development of Costa Fuego, securing seawater extraction rights, surface rights for mining activities, easement corridors for water and power pipelines, and electrical connection to the national power grid as well as entering into a LOI with the nearby port of Las Losas. Costa Fuego has exceptional ESG credentials due to the abundance of existing infrastructure, amenability of ore processing using seawater, potential to operate Costa Fuego on a 100% renewable power mix, minimal community impact and ability to drive growth in an economically deprived area. Hot Chili's growth trajectory continues with the recent announcement of further consolidation contiguous with the bulk of its resources. This new, low-cost, acquisition contains near surface copper-gold porphyry mineralization intersected in historic drilling that has yet to be followed up.
The Company commenced an initial 10,000m drill program in January 2023 to test highly prospective copper-gold porphyry targets along strike of the existing porphyry cluster. Hot Chili recently obtained secondary listings on the TSXV and OTCQX to better align with the exchanges of its global copper peer group. The Company aims to narrow the relative valuation gap with its North American listed peers, particularly as the general market starts to appreciate the medium term structural deficit in copper – the critical commodity – and the copper price required to incentivize new production.
