Sable Provides 2023-2024 Field Season Exploration Update for Don Julio Project in San Juan, Argentina

VANCOUVER, April 02, 2024 - Sable Resources Ltd. ("Sable" or the "Company") (TSXV:SAE | OTCQB:SBLRF) is pleased to provide an update on the just completed 2023-2024 field season at the Don Julio Project in San Juan, Argentina ("Don Julio" or the "Project"). All exploration expenditures at Don Julio are fully funded under the Earn-In Agreement between the Company and a subsidiary of South32 Ltd. ("South32"), signed in 2021.

Highlights

• US$1.2M invested this season for surface fieldwork at Don Julio.
• 507 rock samples were collected during the season (Figure 1) with all samples having been received and analyzed for gold, multi-elements, and spectral signature.
• 628 soil samples were collected over the Tocota target with results showing good coincidence of Cu with the outcropping mineralization and interesting anomalies of Mo, Bi, As, and Te located NW of the porphyry zone and at higher elevation. These pathfinder anomalies suggest extension of the known mineralization towards the NW at depth. The soil anomalies and the observed porphyry mineralization coincide with a very strong, vertical magnetic anomaly.
• Detailed structural mapping has defined the main structures within the Project and target zones with favourable structural preparation.
• A 21 km IP survey was conducted along the main Chita valley obtaining two new chargeability anomalies.
• Colorado, a new drilling target has been generated after combining new geophysical data with historical field observations.
• The Poposa target where the Company drilled holes DJ-DH-22-01, 02, and 03 in 2022 has been expanded to include the Morro zone where new interesting surface observations suggest the presence of a porphyry system at depth.
• Geological mapping has covered some existent gaps, and the geology team has reviewed WorldView3 anomalies generated in the last field season (2022/2023). All targets are drill ready for next season and the Company is advancing on the workplan and budget with a subsidiary of South32 in accordance with the terms of the Earn-In Agreement.

Dr. Ruben Padilla, Sable's President, and CEO, commented, "We are very pleased with the work completed this season at Don Julio. Our focus this year on field work has allowed us to better understand the geology and mineral potential of Don Julio. With a cluster of four potential Miocene porphyry centers in an area of ~7 x 6 km including La Gringa, Morro-Poposa, Tocota, and Punta Cana, we're now moving forward with defining the 2024/2025 budget and objectives for our next drilling campaign."

vs rock sampling from previous seasons (yellow).

Rock sampling and mapping this season was focused outside of the known lithocap, on the eastern portion of the Project, which has been historically less explored. Detailed mapping and rock sampling at the Tocota target revealed the association of the mineralized veinlets with a diorite intrusion which shows a strong magnetic anomaly. The soil sampling confirmed the possibility of additional concealed mineralization to the NW underneath rocks with strong pathfinder anomalies such as Mo, As, Sb, Te, Bi, S (Figure 2).

The IP lines acquired along the main Chita valley revealed two new chargeability anomalies: Gringa NE, and Colorado. While Gringa NE is an interesting low-angle IP feature dipping to the East; Colorado is a very strong, vertical, dome-shaped IP anomaly covered by Quaternary gravels at 4,100 m.a.s.l. The Colorado IP anomaly seems to be connected with the previously known Colorado breccia; a magmatic hydrothermal breccia outcropping at 4,900 m.a.s.l. which contains mineralized porphyry fragments and is strongly affected by advanced argillic alteration, and that has returned values up to 3.9% Cu and 13 g/t Au (Figure 3). The new Colorado chargeability anomaly is located 3.2km east of the nearest drill hole, considerably extending the size of the hydrothermal system. The lower elevation of the geophysical feature (4,100) would allow drilling in a much better position.

The Poposa target where the Company drilled three holes in 2022 (DJ-DH-22-01, 02, 03) has been integrated with the Morro zone where historical hole ATW-05 was drilled vertically into a large diatreme breccia system which contains fragments of biotite altered rocks; also, at Morro multiple hydrothermal breccias with fragments of porphyry veinlets were found outcropping in proximity to the mentioned diatreme. The combination of these new and historical observations indicates the presence of a porphyry system that has not been tested yet and will be an integral part of our next drilling campaign (Figure 1).

ABOUT THE DON JULIO PROJECT

The Don Julio project comprises 69,350 hectares in the Cordillera Frontal in San Juan, Argentina. It includes the Don Julio cluster that contains numerous targets of porphyry (La Gringa, Poposa, Amarillo, Punta Cana, Tocota, Colorado); intermediate sulfidation (Lodo, San Gabriel, Colorado); skarn (Fermin); and the regional properties that include the Los Pumas project as well as extensive unexplored ground. Since 2018, Sable has conducted systematic surface work including mapping; rock sampling; talus sampling; GroundMag; UAV-Mag; and induced polarization. Sable performed a first drilling campaign in 2018-2019 with 3,101m drilled in 11 holes, a second campaign in 2021- 2022 comprising 4,294m in 9 holes, and a third campaign in 2022-2023. In 2021, Sable signed an Earn-In agreement with a subsidiary of South32 to jointly explore the Don Julio project.

SAMPLE PREPARATION AND QA/QC

Sample preparation for projects in Argentina is carried out by ALS Chemex Argentina, a subsidiary of ALS Minerals, at its facility located in Mendoza, Argentina. Analyses are 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 press 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. Control samples (standards, blanks, and duplicates) are inserted systematically, and their results evaluated according to the Company protocols.
