Sable Announces Moxico-Funded Exploration Program and 3,500m Drill Program at the El Fierro Project, San Juan, Argentina

VANCOUVER, British Columbia, Sept. 29, 2026 (GLOBE NEWSWIRE) -- Sable Resources Ltd. ("Sable" or the "Company") (TSXV:SAE | OTCQB:SBLRF) is pleased to announce that its partner, Moxico Resources plc ("Moxico"), has approved funding for the upcoming spring-summer exploration season at the El Fierro Project in San Juan Province, Argentina.

The approved exploration program includes regional geological reconnaissance and target generation across underexplored areas of the El Fierro property, a Spartan Magnetotelluric ("MT") geophysical survey to be conducted by Quantec Geoscience, and 3,500 metres of diamond drilling at the Pyros porphyry Cu-Au-Mo system.

Regional exploration will focus particularly on the southwestern portion of Sable's large El Fierro land package, where extensive areas have received limited detailed exploration to date. The objective of this work is to evaluate additional prospective areas and generate new targets outside the currently known Pyros mineralized system.

The planned MT geophysical survey will cover the entire Pyros porphyry system with a vertical penetration of up to 2km and will be integrated with existing geological, geochemical, and geophysical datasets to help refine the new drill phase. MT has become an essential tool for porphyry exploration with conductivity anomalies showing strong correlation with Cu-Au-Mo mineralization in many Andean porphyry systems such as Altar, Valeriano, Piuquenes, and many other examples around the world.

Regional field exploration and the MT geophysical survey is planned to commence in November 2026, with drilling anticipated to commence during the second week of January 2027.

Dr. Ruben Padilla, President and CEO of Sable, stated, “We are pleased that Moxico has approved the next phase of exploration at El Fierro. The program provides a good balance between advancing the Pyros porphyry system through an additional 3,500 metres of drilling and continuing systematic exploration across the land package. To date, most drilling at Pyros has focused on the central portion of the known porphyry footprint. The upcoming drill program is designed to extend the known ring-shaped Cu-Au-Mo mineralization, expand the high-grade breccia zones intersected in previous drilling, and begin testing the undrilled southern and western extensions of the system. We consider the southern area particularly important, as the main sericite-chlorite mineralizing event may be better preserved in this part of the system.”

ABOUT THE EL FIERRO PROJECT

El Fierro Project is located 250 km northwest of San Juan city, and 110 km south of the world-class Vicuna district which contains the Josemaria, Filo del Sol, and Lunahuasi deposits. El Fierro is a large (10 km x 10 km) Miocene magmatic–hydrothermal system surrounding the Pyros Cu-Au-Mo porphyry centre; Pyros was discovered by Sable during the 2021-2022 drilling campaign. Sable drilled 13 holes at Pyros in 2022, discovering a large, multiphase Miocene-age stock hosted within Permian granitic rocks. Multiple holes intercepted significant intervals of Cu-Mo-Au mineralization. On February 27, 2025, the Company entered into an agreement with Moxico Resources, which grants Moxico an option to earn up to a 51% interest in the El Fierro Project by completing a series of exploration expenditures and payments over five years, with the option to earn up to 70% by completing a feasibility study.
