Sable identifies 2.6 km chargeability-conductivity anomaly at Zorro, Argentina

VANCOUVER, British Columbia, June 29, 2026 (GLOBE NEWSWIRE) -- Sable Resources Ltd. ("Sable" or the "Company") (TSXV: SAE | OTCQB: SBLRF) is pleased to report the results of a recently completed Induced Polarization (IP) survey conducted at its Zorro Project in San Juan, Argentina. The Company completed 17.8 km of IP distributed along four east-west-oriented lines covering the main Zorro airborne magnetic anomaly and the known target areas (Zorro Copper, Zorro North, and Zorro Breccia, Figure 1). The survey successfully identified a strong, coherent chargeability-conductivity anomaly extending for at least 2.6 km along the eastern margin of the main magnetic anomaly (Figure 2).

The newly identified geophysical feature represents a significant target within the Zorro district and will be tested during the Company's inaugural drill program, planned to commence in mid-July. Highlights 17.8 km IP survey completed over the central portion of the Zorro district. Strong chargeability and conductivity anomalies were outlined close to the eastern limit of the magnetic diorite stock, near its contact with Paleozoic siliciclastic host rocks.

The IP anomaly is consistently exceeding 50mV/V on all four lines extending for at least 2.6 km in strike length. The southern portion of the anomaly is spatially associated with the Zorro Breccia target. Chargeability and conductivity match with each other and show a vertical and deeply rooted geometry, remaining open to depths >800 m.

This geometry suggests association with mineralized intrusions or breccias. The geophysical anomalies are open to the south, projecting towards the recently optioned "El Acero" property and towards the large polymetallic breccia system of Chinchillones within the Minsud/South32 Chita Valley project.  Dr. Ruben Padilla, President and CEO of Sable, commented, "The new IP data adds an important layer of information to our ongoing drill target definition work and further strengthens our confidence in the scale and exploration potential of the Zorro intrusive-related mineral system. The size, continuity, and depth extent of this feature make it a compelling target and an important component of our upcoming inaugural drill program." Figure 1 .

Discussion of the Induced Polarization Survey Quantec Geosciences was engaged by Sable to conduct a 17.8 km Induced Polarization survey across the main Zorro magnetic anomaly and the known, outcropping mineralized zones, distributed over four E-W-oriented lines (6,200N, 6,800N, 7,400N, and 8,800N).

Oblique view of the Zorro project, looking north, showing the RTP magnetic anomaly in the background and vertical chargeability sections along the four surveyed lines with well-developed highs on the east, and with the locations of the known targets for reference. The survey revealed shallow chargeability and conductivity anomalies for Zorro North and Zorro Copper as expected for outcropping sulphide mineralization in an intrusive cupola setting.

However, the most interesting result of the IP survey is the discovery of a strong and consistent chargeability/conductivity anomaly located along the eastern margin of the main magnetic anomaly. The IP anomaly trends approximately NNE and is recorded across all four IP lines where it consistently exceeds 50mV/V over a distance of at least 2.6 km (Figure 2). Both the chargeability and conductivity IP anomalies are steeply dipping to subvertical and remain open at depths approaching 800m.

Along the southern-most IP line (6,200N), the Zorro Breccia target is spatially located on the western margin of the IP anomaly, suggesting a connection between the outcropping breccia and a much larger mineralized intrusion or breccia system at depth (Figure 3). The consistent spatial coincidence between breccias, intrusions, and rock sample Cu-Au anomalies identified by Sable to date, suggests that the IP features may be related to mineralization and the larger scale magmatic-hydrothermal system observed at the Zorro Project.

The close spatial relationship suggests that these features are likely associated. 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.

Zorro 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 Zorro. 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.
