Sable Reports Drill Results Extending the Pyros Cu–Au–Mo

Porphyry System, San Juan, Argentina

VANCOUVER, CANADA – April 13, 2026 – Sable Resources Ltd. ("Sable" or the "Company") (TSXV:

SAE | OTCQB: SBLRF) is pleased to report positive results from its most recent drill program at the

El Fierro Project ’s Pyros porphyry system , located in San Juan Province, Argentina. The drill

program was undertaken between November 2025 and January 2026 and consisted of 11 drill holes

totaling 3,466 metres. The program was fully funded by Moxico Resources plc (“Moxico”) under the

Moxico earn-in agreement (see news release dated February 27, 2025).

Results from the drill program continue to define a large, continuous Miocene Cu–Au–Mo porphyry

system hosted within Permian granites and diorite intrusions. Drilling to-date and the resulting

integrated interpretation now outline s a mineralized footprint of approximately 720 m by 580 m,

centered on an early mineral, strongly altered, barren-to-low-grade porphyry stock (Figure 1).

Interpretation of the drill data, combined with surface mapping, geophysics, and geochemistry, has

significantly improved the understanding of the geometry of the system. Mineralization follows a

coherent pattern, particularly along its western margin, and remains open to the south and to the

north beneath sub-cropping Permian host granite. Strong molybdenum and copper soil anomalies,

porphyry-style veining, and remnants of advanced argillic alteration indicate potential for further

extension of the mineralized system (Figure 3).

Dr. Ruben Padilla, President and CEO of Sable Resources Ltd., commented,

“Based upon these and prior results, mineralization at Pyros follows a well -defined ring -shaped

geometry, which has now been confirmed by multiple drill holes. This drilling has significantly

improved our understanding of the system, which is evolving into a large and coherent mineralized

porphyry system with defined higher-grade zones that remain open for expansion.

“Pyros represents one of the most recent significant porphyry discoveries in San Juan Province. It is

located only 120km south of the Vicuña district, in one of the most prospective emerging mining

jurisdictions in the Americas. Sable’s partner Moxico is encouraged by the results and quality of the

systematic work completed by the Sable team. Our future drilling will focus on expanding the known

high-grade zones, and the broader surface anomaly and untested targets to the south of the current

drill area.”

Drilling Highlights

FZ-DH-25-92

Hole FZ-DH-25-92 was originally drilled in April 2025 to the depth of 401m ending in mineralization and

then extended during the most recent campaign to a depth of 597m. The hole extension intercepted 79.5m

of additional mineralization from 401 to 480.5m. Combining the previously released intervals of hole 92

with the new results and expressing them as CuEq, we have:

Geological Description

The Cu-Au-Mo mineralization intercep ted by most of the drill holes reported in this news release

follows a ring geometry elongated in a NNE direction. Within the ring, mineralization is hosted

within different phases of Miocene diorite intrusions as well as within the Permian granite host.

Varying mineral and alteration assemblages are observed within the mineralized ring including

chalcopyrite, molybdenite, and sericite filling dissolution cavities, chalcopyrite and molybdenite

disseminated or within veinlets in potassic altered diorites, and chalcopyrite cementing magmatic -

hydrothermal breccias. The mineralized ring appears to surround a weakly mineralized high -

temperature biotite-albite altered diorite core.

Figure 2. 3D modelling of the Cu-Au-Mo mineralized zone at Pyros. (A) shows a plan view that

illustrates the two mineralized corridors with most of the recent drilling concentrated on the

western margin. (B) shows an EW cross section along the main drilling fence showing the currently

known geometry of the high-grade breccias intercepted on both flanks of the system.

Upside Potential

The current drilling defines a large and continuous mineralized system that remains open in multiple

directions (Figure 2). Future work will focus on expanding higher -grade zones associated with

magmatic-hydrothermal breccias and testing undrilled targets to the south, where geochemical and

alteration signatures indicate strong potential for additional mineralization (Figure 3).

True width of the mineralization is unknown at this point. Copper Equivalent has been calculated

using prices of US$4.00 per pound of Cu, US$3,000 per ounce of Au, and US$22.00 per pound of Mo.

Given that no current or historical metallurgical studies are available, recoveries of 90% for all

metals have been assumed based on comparisons with similar projects in South America and

Canada.

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

-7-

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 program. 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 Resources, which grants Moxico an option

to earn up to 51% of the El Fierro Project by completing a series of investments and payments during

five years.
