Sable Announces Upcoming Drill Program at the Pyros Cu-Au-Mo Porphyry System and Provides an Exploration Update on the Cerro Negro Project, San Juan, Argentina
VANCOUVER, British Columbia, Sept. 22, 2025 (GLOBE NEWSWIRE) -- Sable Resources Ltd. ("Sable" or the "Company") (TSXV:SAE | OTCQB:SBLRF) is pleased to announce a new drilling campaign at its El Fierro project, specifically targeting the recent Pyros Cu-Au-Mo porphyry discovery, as outlined in previous press releases. The upcoming campaign will consist of 3,500m of core drilling, extendable to 5,000m, based upon results (Figure 1). The Company will soon commence camp preparation, aiming to initiate drilling in late October.
Dr. Ruben Padilla, President and CEO of Sable, commented, “Sable’s successful drilling campaign at the Pyros porphyry target earlier this year, led to the discovery of two blind Cu-Au-Mo mineralized breccias along with additional mineralized zones. This next drill campaign will focus on extending these discoveries both along strike and at depth, while also testing, for the first time, the northern portion of the porphyry system, located 1.8 km north of the area drilled to date.”
This 3,500m drilling campaign will be funded by Moxico Resources plc (“Moxico”). Sable and Moxico entered into a Letter Agreement on February 27, 2025 (the “Letter Agreement”) that, in part, granted Moxico with the option to earn up to 51% of the El Fierro project by completing 20,000m of drilling over five years, with a minimum of 1,600m in the first year (see press release of February 27, 2025). To date, Moxico has completed 1,441m of the 1,600m. In consideration for Moxico advancing the 3,500m drilling campaign earlier than required under the Letter Agreement, Moxico and Sable have entered into an amendment to the Letter Agreement reducing the 20,000m of drilling over five years to 10,000m of drilling over five years. All other terms of the Letter Agreement remain unchanged.

Cerro Negro Property (San Juan) Update
Sable has been advancing exploration work at the Cerro Negro property since 2023. The property represents an innovative play in generative exploration, targeting porphyry-style mineralization located below Quaternary gravels of Argentina’s Pre-Cordillera, within an area of excellent access and infrastructure. The area enjoys the advantage of being workable year-round. In 2023, Sable targeted a regional magnetic anomaly coincident with outcropping Miocene intrusions. Initial work discovered a chargeability anomaly and significant Au-Ag-Cu-Mo anomalies reflected in MMI samples placed along the IP lines.
Sable’s 2025 ‘fall-winter’ (April to October in the Southern Cone) program at Cerro Negro was the first to be financed by Moxico. The program included completion of 48 km of new IP lines and an additional 660 MMI samples in gravel cover, looking for geochemical anomalies above or around the geophysical features. Geochemical analyses are pending and the final interpretation of the IP data is underway.
SAMPLE PREPARATION AND QA/QC
Sample preparation for projects in Argentina is carried out by ALS Minerals, at its facility located in Mendoza with analyses carried out at their 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% passing less than 2 mm, sample splitting using a riffle splitter, and pulverizing a 250 g split to at least 85% 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, 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 is sent to AISIRIS Australia to be processed and interpreted.
Control samples (standards, blanks, and duplicates) are inserted systematically, and their results 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 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 signed a letter agreement with Moxico, which grants Moxico an option to earn up to 51% of the El Fierro Project by completing the following within a five- year period: (1) 20,000 metres of drilling, with a minimum of 1,600 metres in the first year; (2) payment of US$1,540,000 worth of property option payments; and (3) payment of US$600,000 to Sable in annual amounts of US$150,000 commencing in year two.
