“The discovery of these two blind mineralized copper-gold-molybdenum breccias, separated by 500m, represents a significant milestone in our effort to understand the mineral potential of the Pyros porphyry system. Our initial drilling campaign that was completed in May 2022 was concentrated along an E-W drill fence that explored what we believed was the centre of the system, however, today's results confirm that our first phase drilling was mainly done over an early, low-grade porphyry phase. The new mineralized drill intercepts are genetically related to breccias and intermineral porphyry phases located at the margins of the low-grade centre. The newly discovered mineralized intercepts are open in the north-south direction as well as to depth, and may be part of a larger, well-mineralized porphyry breccia complex. Now that we better understand the geometry and ore controls of the system, it will allow us to expand our exploration efforts along the almost 4km of phyllic alteration that remain undrilled”, stated Dr. Ruben Padilla, President and CEO of Sable, who added, “We appreciate the financial support of our new partner Moxico who fully funded this drilling campaign and we look forward to starting the next drilling program in Q4 2025.”

Location of the drill section presented in Figure 4 with respect to the footprint of the Pyros system showing the extension of the sericitic alteration, magnetic anomaly and molybdenum highest anomalies from 2022 soil sampling. The map clearly shows the potential to extend the intercepted Cu-Au-Mo mineralization along strike.

Hole Descriptions

Four holes were drilled in this campaign: FZ-DH-25-68; FZ-DH-25-76; FZ-DH-25-91 and FZ-DH-25-92. In order to optimize resources, three of the holes were drilled as extensions of previous holes drilled in 2022. The goal of this drilling campaign was to test down-dip continuity of reported anomalous intervals and to achieve an understanding of local ore controls. These new drilling results show that the most significant copper – gold – molybdenum mineralization is located at both margins of a low-grade diorite porphyry intrusion. Results have been received for three of the holes mentioned above while results from hole 91 are still pending.

FZ-DH-25-92

Hole FZ-DH-25-92 was drilled subvertically between holes FZ-DH-22-68 and FZ-DH-22-72 from the 2022 drilling campaign. Both of these holes showed encouraging alteration and Cu-Au mineralization in their upper parts, with individual values up to 0.54% Cu and 0.32 g/t Au. The objective of hole 92 was to investigate the vertical extent of such alteration and anomalous grades. The hole encountered consistent Cu-Au-Mo mineralization in granitic host rock, diorite dykes, and local hydrothermal breccia from the top of bedrock to around 116m depth. A second mineralized zone starts around 291m depth to the end of hole, with the strongest mineralization centred on a 53-m magmatic-hydrothermal breccia which is intensely mineralized towards its lower contact; below the breccia, continuous mineralization was observed in granite and potassic-altered diorite. The hole ended in diorite with 0.19% Cu and 568 ppm Mo, with the mineralization remaining open to depth. The interval separating the two copper-mineralized zones averages 172 ppm Mo over 157.15m.

FZ-DH-25-68

Hole FZ-DH-25-68 was drilled from west to east as an extension to FZ-DH-22-68 from 350 to 767m. After crossing the low-grade porphyry, the hole intersected a blind magmatic-hydrothermal breccia over an interval of at least 50m (not true width). The breccia has granite fragments, with a cement of magnetite-chlorite close to its upper contact transitioning to sericite, quartz, tourmaline, and chalcopyrite towards the lower contact. The geometry and size of the breccia is yet to be defined with future drilling.

FZ-DH-25-76

Hole FZ-DH-25-76 was drilled from east to west as an extension of FZ-DH-22-76 with the objective of intersecting the Cu-Mo mineralization observed in hole FZ-DH-22-78 at deeper levels. The hole intersected 110m of disseminated chalcopyrite and molybdenite in granite host rock, with individual assays up to 0.77% Cu and 529 ppm Mo.

Note how the main mineralized zones from 2022 and 2025 are located on both margins of a low-grade early porphyry intrusion. Grades <0.1% Cu and 50ppm Mo have been removed to highlight the reported intercepts.

Including	365.0	414.0	49.0	0.22	0.11	108

True width of the mineralization is unknown at this point. Although not included in the table above, the rhenium content of the mineralization encountered in hole FZ-DH-25-92 is significant, averaging 382.95m @ 0.22 g/t Re and with individual values up to 5.23 g/t Re. Rhenium is a critical metal due to its importance in the aerospace and petrochemical industries; Rhenium is a byproduct of molybdenum concentrates which, in turn, are a byproduct of Cu-Mo or Cu-Au-Mo porphyry deposits. Re grades observed in hole 92 are comparable to many of the largest porphyry deposits in Chile, US, and Canada for which Re data are available¹.

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 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. ALS additionally collects a subsample from the coarse reject to be analyzed by Terraspec; spectral data is 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 EL FIERRO PROJECT

El Fierro Project is located 250 km northwest of San Juan city, 120 km north of Sable’s Don Julio Project, and 110 km south of the world-class Filo del Sol porphyry system. El Fierro is a large (10 km x 10 km) Miocene magmatic–hydrothermal system surrounding the Pyros Cu-Au-Mo porphyry centre; Pyros was discovered by Sable during the 2021-2022 drilling campaign. Sable drilled 13 holes at Pyros in 2022, discovering a large, multiphase Miocene-age stock hosted within Permian granitic rocks. Multiple holes intercepted significant intervals of Cu-Mo-Au mineralization. On February 27, 2025, the Company signed a letter agreement with Moxico, which grants Moxico an option to earn up to 51% of the El Fierro Project by completing the following within a five- year period: (1) 20,000 metres of drilling, with a minimum of 1,600 metres in the first year; (2) payment of US$1,540,000 worth of property option payments; and (3) payment of US$600,000 to Sable in annual amounts of US$150,000 commencing in year two.
