Sable Samples up to 4.38% Cu, 140 g/t Au, and 584 g/t Ag in Preliminary Sampling Program at the Zorro Project, San Juan, Argentina

VANCOUVER, British Columbia, Jan. 22, 2026 (GLOBE NEWSWIRE) -- Sable Resources Ltd. ("Sable" or the "Company") (TSXV:SAE | OTCQB:SBLRF) is pleased to announce that it has received results for 55 out of a total of 98 rock samples collected during a preliminary review of its recently acquired Zorro Project in San Juan, Argentina (see Sable’s news release dated January 15, 2026).

This initial review was focused on some of the historic artisanal mining occurrences located around the 7km by 4km Zorro magnetic anomaly. Sample results returned highly encouraging values of Cu, Ag and Au (with associated Pb, and Zn), within three distinct areas of the property. Notably, however, most of the Zorro property remains completely unexplored.

Of the 55 sample results received, 19 samples returned values higher than 0.1% Cu with maximum values of 4.38% Cu; 19 samples returned values greater than 1 g/t Au with maximum values of 140.5 g/t Au; 19 samples returned values greater than 10 g/t Ag reaching maximum values of 584 g/t Ag. In addition, 18 samples returned values over 0.1% Pb.

The observed mineralization styles, and apparent geochemical/alteration associations and zoning define three separate, aerially significant target areas (Figure 1):

Zorro Copper

The Zorro Copper target area is well defined within a zone of approximately 650m by 500m. Sampling returned multiple values grading >0.1% Cu, and up to 4.38% Cu (Figure 2 and Table 1). Observed mineralization consists of sheeted quartz-carbonate veins and veinlets containing chalcopyrite, hematite and magnetite, hosted within Permian granite (Figure 3). In addition to Cu, sampling returned significant Ag values, up to 114 g/t Ag. Silver appears broadly correlative with Cu, with 73% of the Zorro Copper samples returning greater than 5 g/t Ag. Furthermore, and importantly, Au values, although less consistent, ranged from <0.1 g/t up to 15.3 g/t Au, with six samples returning >0.1g/t Au (Figure 2 and Table 1). Typical of Intrusion-Related mineralization, Bi, Te, and W are anomalous, and in this case, generally correlative with Au values. Sable’s next steps will include detailed mapping and sampling of this large-scale, outcropping Cu (Ag, Au) system.

Zorro Veins

Located northeast of the Zorro Copper zone, the Zorro Veins zone comprises a series of quartz-carbonate-pyrite veins that have been historically exploited in artisanal mine workings. Sable’s sampling program returned high-grade values up to 140 g/t Au and 584 g/t Ag, including 7 samples that returned >5g/t Au (Figure 1, Table 1). The sulphide mineralogy of the veins includes galena (one sample reported >20% Pb), sphalerite, local chalcopyrite and arsenopyrite. Sable’s geology team considers the vein system to be of intermediate-sulphidation epithermal nature. Sable will conduct detailed mapping and further sampling of the veins to define their distribution, continuity, grade, and depth potential, as well as to ascertain their significance as geochemical vectors to non-outcropping mineralization in the vicinity.

Zorro Bx

The Zorro Bx zone outcrops 900 metres east of the Zorro Copper target. It represents a high-level magmatic-hydrothermal breccia, containing clasts of sedimentary country rock with quartz-sericite-pyrite cement. Samples collected from the breccia returned well defined epithermal pathfinder element anomalies, including for As, Ba, Mn, Sb, with lesser anomalies for Mo, and Pb. Additional geological and alteration mapping, sampling and geophysical surveys will be used to study the Zorro Bx zone, and to determine its possible transition to Cu and/or Au-Ag mineralization at depth.

Dr. Ruben Padilla, President and CEO of Sable, commented, “We are highly encouraged by this set of initial results. The widespread nature and variability of mineralization and alteration observed at the Zorro Project speaks to its potential to host bulk-tonnage Cu (Ag, Au) deposits (e.g. Zorro Copper) and high-grade Au-Ag (Pb, Zn) deposits (e.g. Zorro Veins). In addition, geochemical and alteration anomalies such as at Zorro Bx can occur peripheral to or above significant porphyry-style Cu or epithermal Au-Ag occurrences. The Zorro Copper zone provides us with a clear fast-track diamond drill target, given the size and strong Cu-Ag-rich signature of outcropping mineralization. Sable’s geology team is advancing detailed surface work at all the above outlined targets, in parallel with widespread prospecting in other areas of this under-explored property. Our work will be greatly facilitated by the ease of access and all-weather altitude (2,600masl) of the project area, which will allow us to advance exploration year round.”

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 been recently consolidated by Sable through signing of an option agreement and ground staking, with a total 5,236-hectare land package. 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.

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 of about 7km by 4km that seems to be caused by a diorite stock which intrudes Carboniferous sediments and Permo-Triassic granites.
