Pampa Metals Options Copper-Gold Project Along San Juan Porphyry Belt. Historical Unaudited Intervals Include 413.5m from 167 @ 0.47% Cu and 0.52 g/t Au (0.87% CuEq)*

VANCOUVER, November 30, 2023 - Pampa Metals Corp. ("PMC" or the "Company") (CSE:PM)(FSE:FIRA)(OTCQX:PMMCF) is pleased to announce that on November 30, 2023 it entered into an option and joint venture agreement with Compañia Minera Piuquenes S.A (a Panamanian entity) to acquire an 80% interest in the Piuquenes porphyry copper-gold project located in the San Juan province, Argentina. Proximal to the globally significant El Pachón (Glencore) and Altar (Aldebaran Resources) Projects, the Piuquenes porphyry copper-gold project has been privately held since its discovery.

Piuquenes Porphyry Copper-Gold Project

The Piuquenes porphyry copper-gold project was first drilled in the 1990's when Inmet Mining Corp. (IMC, subsequently acquired by First Quantum in 2013) completed 8 diamond drill holes for a total of 1,894.2m. Significant intersections of copper and gold, included:
• 413.5 m (167-580.5 m) @ 0.47% Cu and 0.52 g/t Au (0.87% CuEq)*;
• 67.5 m (207-274.5 m) @ 0.63% Cu and 0.51 g/t Au (1.02% CuEq)*; and
• 158 m (3-161 m) @ 0.32% Cu and 0.6 g/t Au (0.78% CuEq)*.

In 2016, Anglo American Argentina (AAA) drilled a single diamond borehole of 920.2 m total length, crossing the mineral intersections discovered by IMC. Climatic events prevented the assaying of the recovered drill core, with only visual observations of a 508 m (362-870 m) interval of copper mineralization described prior to AAA's withdrawal from the project.

Following completion of its Due Diligence, Pampa Metals considers the project to be highly prospective and drill-ready, owing to a solid technical foundation, including well-preserved historic drill cores and 3D modelling, and anticipates commencing follow-up drilling in January 2024.

As part of its Due Diligence, Pampa Metals has re-logged and assayed the AAA Diamond Drill Hole with results expected from ALS Mendoza in early December. The Company has also reviewed the IMC diamond drill core and observed visual mineralization, without yet completing QA/QC. The Company awaits the imminent assay and QA/QC results of the AAA PIU-16 920m diamond drill hole, prior to finalizing its drill program planning.

Commenting on the transaction, Joseph van den Elsen, President and CEO, stated:

"Pampa Metals is pleased to announce this company making transaction and the acquisition of a flagship project, privately held since its discovery. Pampa considers the historical drill intercepts to be highly encouraging and indicative of the Piuquenes Project's potential to host a significant near-surface, high-grade porphyry copper-gold deposit in a world class location. Our Executive Team remains in Argentina working with stakeholders and finalizing plans to initiate a follow-up diamond drilling program in January 2024."

Project Location and Exploration History: Piuquenes porphyry copper-gold deposit

The Piuquenes Project consists of nine mining titles that cover an area of ~1,880 ha in the San Juan Province of Argentina, adjacent (to the north) with the Altar copper-gold porphyry project (Aldebaran Resources Inc.) and approximately 190 km west of the city of San Juan. Other large porphyry copper projects in the San Juan Miocene porphyry belt include, El Pachón (Glencore), approximately 30 km to the south, the operating Los Pelambres copper mine (60% Antofagasta plc) in Chile, and Los Azules (McEwen Mining) 50 km to the northeast.

The first evidence of copper oxides at Piuquenes was reported in 1970 by Compañia MInera Aguilar S A, who subsequently completed the first exploration program between 1973-1975. Between 1995 and 1997, Inmet Mining Corp. (IMC) completed a heli-magnetic/radiometric survey, surface geology, rock and soil geochemistry, ground magnetics, PD-IP and eight diamond drillholes (DDH-P1A to DDH-P8A) for a total of 1,894.2m. Subsequently, in 2015-2016, Anglo American Argentina (AAA) completed detailed 1:2,500 geology and geochemistry, 17.8 km of gDAS24 deep 3D PD-IP/NSMT and a 920.2 m diamond drill hole (PUI16-DDH01).

Since its discovery, the Piuquenes Copper-Gold porphyry has remained privately held.

Follow-Up drilling

Pampa Metals has designed a diamond drill program to be completed across two drilling seasons which will be reviewed and finalised upon the imminent receipt of the assay and QA/QC results of the AAA PIU16-DDH01 920m diamond drill hole.

Phase 1 consists of a ~2,500 diamond drill program designed to test the depth and lateral extension of known mineralisation, to be completed between January - April 2024 (indicative) with assays results expected progressively between March and May 2024 (indicative).

Phase 2 consists of a six-month drill program designed to significantly expand the mineralised envelope and scheduled to commence in October 2024 (indicative).

Commercial Terms - Option & Joint Venture Agreement

On 30 November 2023 the Company entered into an Option & Joint Venture Agreement with Compañia Minera Piuquenes S.A (a Panamanian entity) comprised of option payments, work commitments and an option exercise price for the acquisition of an 80% direct interest in the Piuquenes project.
