SABLE REPORTS DRILL RESULTS EXTENDING THE PYROS CU-AU-MO PORPHYRY SYSTEM, SAN JUAN, ARGENTINA

Sable Resources Ltd. has released 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 totalling 3,466 metres. The program was fully financed by Moxico Resources PLC under the Moxico earn-in agreement (see news release dated Feb. 27, 2025).

Results from the drill program continue to define a large, continuous Miocene copper-gold-molybdenum 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, centred on an early mineral, strongly altered, barren-to-low-grade porphyry stock.

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 subcropping 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.

Dr. Ruben Padilla, president and chief executive officer of Sable Resources, 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 120 kilometres south of the Vicuna 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."

FZ-DH-25-92

Hole FZ-DH-25-92 was originally drilled in April, 2025, to the depth of 401 m ending in mineralization and then extended during the most recent campaign to a depth of 597 m.

Geological description

The Cu-Au-Mo mineralization intercepted by most of the drill holes reported in this news release follows a ring geometry elongated in a north-northeast direction. Within the ring, mineralization is hosted within different phases of Miocene diorite intrusions as well as within the Permian granite host. Varying mineral and alteration assemblages are observed within the mineralized ring, including chalcopyrite, molybdenite and sericite filling dissolution cavities, chalcopyrite and molybdenite disseminated or within veinlets in potassic altered diorites, and chalcopyrite cementing magmatic-hydrothermal breccias. The mineralized ring appears to surround a weakly mineralized high-temperature biotite-albite altered diorite core.

Upside potential

The current drilling defines a large and continuous mineralized system that remains open in multiple directions. Future work will focus on expanding higher-grade zones associated with magmatic-hydrothermal breccias and testing undrilled targets to the south, where geochemical and alteration signatures indicate strong potential for additional mineralization.

Sample preparation and quality assurance/quality control

Sample preparation for projects in Argentina is carried out by ALS Minerals at its facility located in Mendoza, with analyses carried out at its laboratory in Lima, Peru. Sample preparation includes drying in an oven at a maximum temperature of 60 C, fine crushing of the sample to at least 70 per cent passing less than two millimetres, sample splitting using a riffle splitter and pulverizing a 250-gram split to at least 85 per cent passing 75 microns (code PREP-31). The samples contained in this news release were analyzed by methods Au-AA24 (fire assay fusion and atomic absorption spectrometry finish) and ME-MS61 (four-acid digestion with mass spectrometry finish); the latter one includes 48 elements (Al, Ag, As, Ba, Be, Bi, Ca, Cd, Ce, Co, Cr, Cs, Cu, Fe, Ga, Ge, Hf, In, K, La, Li, Mg, Mn, Mo, Na, Nb, Ni, P, Pb, Rb, Re, S, Sb, Sc, Se, Sn, Sr, Ta, Te, Th, Ti, Tl, U, V, W, Y, Zn and Zr). Both digestion methods dissolve most minerals, but not all elements are quantitatively extracted in some sample matrices. ALS additionally collects a subsample from the coarse reject to be analyzed by Terraspec; spectral data are sent to Aisiris Australia to be processed and interpreted.

Control samples (standards, blanks, and duplicates) are inserted systematically, and their results are evaluated according to the company protocols.

About the El Fierro project

El Fierro project is located 250 km northwest of San Juan city, 120 km north of Sable's Don Julio project and 110 km south of the world-class Filo del Sol porphyry system. El Fierro is a large (10 km by 10 km) Miocene magmatic-hydrothermal system surrounding the Pyros Cu-Au-Mo porphyry centre; Pyros was discovered by Sable during the 2021-2022 drilling program. 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 Feb. 27, 2025, the company signed a letter agreement with Moxico Resources, which grants Moxico an option to earn up to 51 per cent of the El Fierro project by completing a series of investments and payments during five years.
