Sable expands Cu-Au footprint at Zorro, San Juan, Argentina

VANCOUVER, British Columbia, July 06, 2026 (GLOBE NEWSWIRE) -- Sable Resources Ltd. ("Sable" or the "Company") (TSXV: SAE | OTCQB: SBLRF) is pleased to report the results of a soil geochemistry survey completed at its Zorro Project in San Juan Province, Argentina. Following up on initial results of geological mapping, structural analysis, systematic rock sampling, and a recently reported IP survey (see press releases dated February 25, April 20, and June 29), the Company has completed a 1,719 sample soil geochemistry program covering the central part of the Zorro claims, including all of the previously described copper and gold+/-silver targets (Figure 1). The soil survey revealed two contrasting yet spatially related mineralized domains within the Zorro target: 1) a Cu-Ag (Au-Bi-W) domain that covers the western half of the soil survey area; and 2) a Au-Ag-Zn (As-Pb) domain that covers the eastern half of the survey area.

The soil geochemical results confirm and significantly extend the footprint of the Zorro Copper and Zorro North targets, described in previous press releases, and highlight a significant new gold anomaly, hereinafter known as Zorro Gold (Figure 3). Highlights The western portion of the Zorro intrusive complex, dominated by outcropping granite to granodiorite, presents a geochemical signature represented by Cu-Ag-Bi-W (±Au) anomalism, characteristic of intrusive-related mineral systems. Two important western area anomalies have been defined: Zorro Copper confirmed by the new soil data.

This rock chip + soil anomaly extends for some 800m by 500m (Figures 1 and 2); and Zorro North where soil geochemical data has significantly extended the footprint of this target to include an area of > 2,000m by 1,000m (Figure 2). Significant parts of this anomaly are covered by unconsolidated gravels. The eastern half of the intrusive complex, of contrasting dioritic composition, presents a geochemical signature dominated by Au-Ag-As-Zn and Pb, apparently related to quartz veins and veinlets with intrusive-related characteristics: The new Zorro Gold anomaly extends for 1,600m by 1,000m and encompasses the area where previous rock sampling reported multiple plus-gram-per-tonne gold values, including samples associated with quartz-sulfide veins and veinlets returning 7 g/t, 13.3 g/t, 34.7 g/t, and 140 g/t Au (Figure 3).

In addition to the above, the magmatic hydrothermal Zorro Breccia zone (reported previously) presents erratic Ag-Mo-Zn-As geochemical signature that may represent leakage from a mineralized source at depth. Upcoming Drill Program Final preparations are underway for a diamond drill program in the second half of July. The objective of this maiden drill campaign is to test the targets identified to date: 1 - Zorro Copper : Drilling will test the strike and depth continuity of the main Cu (Ag-Au) mineralized structural corridors, which host chalcopyrite veins and veinlets. 2 - Zorro North: Drilling will evaluate the vertical continuity, geometry, and grade potential of the potassic-altered granitic intrusive phase characterized by chalcopyrite mineralization contained within miarolitic cavities. 3 - Zorro Breccia: Drilling will test for vertical metal zonation, following surface pathfinder element anomalies within the breccia’s upper cupola toward potential higher grade mineralized zones at depth. 4 - IP Anomaly: Drilling will investigate the source and geological significance of the newly identified conductivity and chargeability anomaly. 5 - Zorro Gold: Drilling may be initiated pending the results of a recently initiated, expanded rock sampling and mapping program on this important new target.

Dr. Ruben Padilla, President and CEO of Sable, commented, “This update reflects the systematic approach that characterizes Sable’s exploration work. Since recognizing the potential of the Zorro project area in December 2025, each stage of exploration has contributed new information that continues to strengthen our confidence in the geological model and the district-scale copper and gold potential of the project. The soil survey has confirmed and expanded the footprint of known targets while identifying new areas of interest, including a significant gold anomaly and a previously unrecognized copper target.

Together with the recently completed geophysical surveys, these results provide a strong framework for our maiden drill program and reinforces our belief that the Zorro Project hosts a large intrusive-related mineral system with multiple mineralized centres.” Figure 1 .

Discussion of Soil Sample Results The soil geochemical results outline two contrasting but spatially related mineralized domains within the Zorro Project: a Cu-Ag (Au-Bi-W), intrusive-centered domain in the west and an Au-Ag-Zn (As-Pb) domain located to the east, along the margin of the intrusive complex. In terms of copper, Zorro North highlights a large anomaly measuring approximately 1,100m by 900m, with a core of > 98th-percentile samples surrounded by a larger envelope of > 93rd-percentile samples. A significant new find is a large Cu anomaly measuring approximately 1,200m by 500m with a NW orientation (Figure 2), located directly east of Zorro North, which may represent an extension of the same style of mineralization in previously unexplored areas.

This new anomaly will see immediate prospecting and sampling. Notably, significant parts of the extended Zorro North anomaly remain open as they are covered by Quaternary gravels (Figure 2). The Zorro Copper target is also clearly reflected on the soil grid with an apparent footprint that is smaller than the observed outcropping mineralization, but showing a possible extension over 600m to the north as revealed by scattered high Cu values in soils interspersed with anomalous rock samples.

Gold is highly anomalous in many rock samples from both Zorro Copper and Zorro North, and this association is reflected by coincident, irregular Au-in-soil anomalies observed at these two targets. However, a new, large, high-grade, and much more consistent gold-in-soil anomaly, Zorro Gold, has been outlined to the southeast of Zorro North. Located on the eastern margin of the main magnetic anomaly (Figures 1 and 3), the estimated size of the Zorro Gold anomaly is 1,600m by 1,000m.

Zorro Gold contains historic artisanal mines where Sable’s previously reported rock chip samples returned values up to 140 g/t Au, and 259 g/t Ag (Figure 3). The discrete veins mined in the artisanal workings also contain pyrite, sphalerite, galena, and arsenopyrite. Accordingly, both rock and the soil samples from Zorro Gold returned strong anomalies of Au, Ag, and Zn with localized As, Pb, and minor Cu.

The size and consistency of the Zorro Gold soil anomaly suggest that more than a few discrete structures may be present. Additional prospecting, mapping, and rock chip sampling are presently underway. Based upon initial rock sampling results at Zorro Copper and Zorro North, significant silver is associated with copper mineralization, and this observation is reflected in recent soil results.

A very strong >98th percentile Ag soil anomaly matches the known mineralization at Zorro North, and a smaller Ag anomaly coincides with Zorro Copper. In addition, a third anomalous Ag zone coincides with the new Zorro gold anomaly and extends to the north in a more scattered fashion. With respect to lead and zinc, these elements display very similar behavior, each forming an anomalous zone around Zorro North and, in general, a possible peripheral halo around all of the Zorro targets.

Both elements accompany gold in the new Zorro Gold zone, and both extend farther north, forming an elongated north-south trend approximately 2,200m long by at least 500m wide. Most of this area remains unexplored to date and thus becomes a high-priority reconnaissance target. Notably, additional strong Pb and Zn anomalies are noted over the Zorro Breccia target.

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. QUALIFIED PERSON Luis Arteaga M.Sc.

ABOUT THE ZORRO PROJECT Sable has recently consolidated the 8,460 ha Zorro Project through the signing of option agreements and the staking of open ground.

The Zorro Project is located in the Frontal Cordillera of San Juan province, directly north of Minsud/South32’s Chita Valley Project, which includes two copper and polymetallic deposits: the Chinchillones deposit 1 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 Deposit 1 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 21 km west of the Zorro Project. The potential of the Zorro Project was recognized through Sable’s regional target generation program.

The project contains a number of mineral occurrences with associated historical workings, spatially surrounding a strong magnetic anomaly measuring some 7 km by 4 km, which appears to be sourced to a diorite stock that intrudes Carboniferous sediments and Permo-Triassic granites typical of the Argentine Frontal Cordillera in the San Juan region.
