Sable Samples Up to 1.36% Cu at new “Zorro North” Target within the Zorro Project, San Juan, Argentina

13:00 Uhr  |  GlobeNewswire

VANCOUVER, Feb. 25, 2026 - Sable Resources Ltd. ("Sable" or the "Company") (TSXV: SAE | OTCQB: SBLRF) is pleased to report the discovery of a new copper-mineralized zone, named Zorro North, located approximately 1.5 km northwest of the previously defined Zorro Cu target, at the Zorro Project in San Juan Province, Argentina (Figure 1). Sable's previously released results from the Zorro Cu and Zorro Veins targets returned values up to 4.38% Cu, 140 g/t Au, and 584 g/t Ag (see Sable's news release dated January 22, 2026).

Zorro North - Geological Description

Mineralization at the new Zorro North target consists of finely disseminated chalcopyrite hosted within Permian granite, locally filling miarolitic cavities. Chip sampling in outcrop returned values up 1.36% Cu, 12.7 g/t Ag, and 0.13 g/t Au (Figures 2 and 3 and Table 1). Importantly:

  • Mineralization is not vein-controlled
  • No strong structural control has yet been identified
  • Copper appears broadly distributed within a granitic cupola

The mineralized granite is exposed beneath partially eroded Quaternary gravels and is interpreted to form part of a large cupola zone extending for more than 2 km2. Surface mapping and sampling outline exposed mineralization over an area measuring at least 700 m by 550 m, remaining open to the east, north and south. Of the 19 samples collected at Zorro North, 13 returned values greater than 0.1% Cu, with consistent Ag values and sporadic Au (Table 1). Sable geologists are currently increasing sample density and expanding map coverage to define the limits and continuity of mineralization.

Dr. Ruben Padilla, President and CEO of Sable, commented, "Initial rock sampling at Zorro North reveals another large-scale, strong, and at-surface Cu anomaly, in a cupula-type setting. Zorro North represents a significant expansion of the mineralized footprint outlined at Zorro Cu and within the overall project area, and highlights the broader copper potential of the property, where multiple mineralization styles, including intrusion-related copper mineralization, hydrothermal breccias, and polymetallic high-grade Au-Ag veins, have already been identified. The property benefits from excellent access and infrastructure, as well as a lower elevation, enabling year-round exploration work. Sable continues to advance Zorro as an internally generated, high-priority project, with the objective of rapidly defining drill targets."

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 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 with spectral data 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 ZORRO PROJECT

The Zorro Project has recently been consolidated by Sable through the signing of an option agreement and ground staking, covering a total of 5,236 hectares. The project is located on the Frontal Cordillera of San Juan, directly north of the Minsud/South32 Chita Valley Project, which includes two copper and polymetallic deposits: the Chinchillones deposit1 containing indicated resources of 188 Mt @ 0.41% CuEq (0.25% Cu, 0.11 g/t Au, 10.6 g/t Ag, 36 ppm Mo, 0.16% Zn) and inferred resources of 573 Mt @ 0.36% CuEq (0.22% Cu, 0.09 g/t Au, 9.0 g/t Ag, 93 ppm Mo, 0.11% Zn); and the Chita South Porphyry Deposit1 containing indicated resources of 33.1 Mt @ 0.43% Cu and inferred resources of 8.6 Mt @ 0.40% Cu. Sable's Don Julio Project, which includes four active porphyry targets (Gringa, Morro, Punta Cana, and Tocota), is located 21km west of Zorro.

The potential of the Zorro Project was recognized through Sable's regional target generation work. The project contains a number of historical mineral occurrences and workings surrounding a large magnetic anomaly measuring about 7km by 4km, which appears to be caused by a diorite stock that intrudes Carboniferous sediments and Permo-Triassic granites.
