Sable Reports Drill Results Extending the Pyros Cu–Au–Mo Porphyry System, San Juan, Argentina VANCOUVER, British Columbia, April 13, 2026 (GLOBE NEWSWIRE) -- Sable Resources Ltd. ("Sable" or the "Company") (TSXV: SAE | OTCQB: SBLRF) is pleased to report positive results from its most recent drill program at the El Fierro Project’s Pyros porphyry system, located in San Juan Province, Argentina. The drill program was undertaken between November 2025 and January 2026 and consisted of 11 drill holes totaling 3,466 metres. The program was fully funded by Moxico Resources plc (“Moxico”) under the Moxico earn-in agreement (see news release dated February 27, 2025). Results from the drill program continue to define a large, continuous Miocene Cu–Au–Mo porphyry system hosted within Permian granites and diorite intrusions. Drilling to-date and the resulting integrated interpretation now outlines a mineralized footprint of approximately 720 m by 580 m, centered on an early mineral, strongly altered, barren-to-low-grade porphyry stock (Figure 1). Interpretation of the drill data, combined with surface mapping, geophysics, and geochemistry, has significantly improved the understanding of the geometry of the system. Mineralization follows a coherent pattern, particularly along its western margin, and remains open to the south and to the north beneath sub-cropping Permian host granite. Strong molybdenum and copper soil anomalies, porphyry-style veining, and remnants of advanced argillic alteration indicate potential for further extension of the mineralized system (Figure 3). Dr. Ruben Padilla, President and CEO of Sable Resources Ltd., commented, “Based upon these and prior results, mineralization at Pyros follows a well-defined ring-shaped geometry, which has now been confirmed by multiple drill holes. This drilling has significantly improved our understanding of the system, which is evolving into a large and coherent mineralized porphyry system with defined higher-grade zones that remain open for expansion. “Pyros represents one of the most recent significant porphyry discoveries in San Juan Province. It is located only 120km south of the Vicuña district, in one of the most prospective emerging mining jurisdictions in the Americas. Sable’s partner Moxico is encouraged by the results and quality of the systematic work completed by the Sable team. Our future drilling will focus on expanding the known high-grade zones, and the broader surface anomaly and untested targets to the south of the current drill area.” Figure 1.

Drilling Highlights FZ-DH-25-92 Hole FZ-DH-25-92 was originally drilled in April 2025 to the depth of 401m ending in mineralization and then extended during the most recent campaign to a depth of 597m. The hole extension intercepted 79.5m of additional mineralization from 401 to 480.5m.
