Sable Announces Upcoming Drill Program at the Pyros Cu-Au-Mo

Porphyry System and Provides an Exploration Update on the

Cerro Negro Project, San Juan, Argentina

VANCOUVER, CANADA – September 22, 2025 - Sable Resources Ltd. ("Sable" or the "Company")

(TSXV:SAE | OTCQB:SBLRF) is pleased to announce a new drilling campaign at its El Fierro project,

specifically targeting the recent Pyros Cu-Au-Mo porphyry discovery, as outlined in previous press

releases. The upcoming campaign will consist of 3,500m of core drilling, extendable to 5,000m,

based upon results (Figure 1 ). The Company will soon commence camp preparation, aiming to

initiate drilling in late October.

Dr. Ruben Padilla, President and CEO of Sable, commented, “Sable’s successful drilling campaign at

the Pyros porphyry target earlier this year, led to the discovery of two blind Cu -Au-Mo mineralized

breccias along with additional mineralized zones. This n ext drill campaign will focus on extending

these discoveries both along strike and at depth, while also testing, for the first time, the northern

portion of the porphyry system, located 1.8 km north of the area drilled to date.”

This 3,500m drilling campaign will be funded by Moxico Resources plc (“Moxico”). Sable and Moxico

entered into a Letter Agreement on February 27, 2025 (the “Letter Agreement”) that, in part, granted

Moxico with the option to earn up to 51% of the El Fierro project by completing 20,000m of drilling

over five years, with a minimum of 1,600m in the first year (see press release of February 27, 2025).

To date, Moxico has completed 1,441m of the 1,600m. In consideration for Moxico advancing the

3,500m drilling campaign earlier than required under the Letter Agreement, Moxico and Sable have

entered into an amendment to the Letter Agreement reducing the 20,000m of drilling over five years

to 10,000m of drilling over five years. All other terms of the Letter Agreement remain unchanged.

Pyros, June 2025 Drilling Results

Three holes drilled in the Pyros Central Zone (Figure 1), between February and April of this year ,

returned very significant Cu, Au, and Mo intercepts, as summarized below.

FZ-DH-25-92

• 20.0m of 0.58% Cu, 0.3 g/t Au, 0.13% Mo from 320.0 to 340.0m

Within a broader intercept of:

109.6m of 0.23% Cu, 0.15 g/t Au, 589 ppm Mo from 291.4 to 401.0m

• 116.2m of 0.24% Cu, 0.14 g/t Au, 197 ppm Mo from 18.0 to 134.2m

FZ-DH-25-68

• 6.9m of 1.01% Cu, 0.35 g/t Au, 258 ppm Mo from 676.8 to 683.7m

Within a broader intercept of:

48.1m of 0.31% Cu, 0.094 g/t Au, 82.5 ppm Mo from 645.6 to 693.7m

FZ-DH-25-76

• 49.0m of 0.22% Cu, 0.11 g/t Au, 108 ppm Mo from 365.0 to 414.0m

Within a broader intercept of:

110.0m of 0.17% Cu, 0.07 g/t Au, 113 ppm Mo from 322.0 to 432.0m

breccia corridors and testing the northern part of the system.

Cerro Negro Property (San Juan) Update

Sable has been advancing exploration work at the Cerro Negro property since 2023. The property

represents an innovative play in generative exploration, targeting porphyry -style mineralization

located below Quaternary gravels of Argentina’s Pre-Cordillera, within an area of excellent access

and infrastructure. The area enjoys the advantage of being workable year -round. In 2023, Sable

targeted a regional magnetic anomaly coincident with outcropping Miocene intrusions. Initial work

discovered a chargeability anomaly and significant Au -Ag-Cu-Mo anomalies reflected in MMI

samples placed along the IP lines.

Sable’s 2025 ‘fall-winter’ (April to October in the Southern Cone) program at Cerro Negro was the

first to be financed by Moxico . The program included completion of 48 km of new IP lines and an

additional 660 MMI samples in gravel cover, looking for geochemical anomalies above or around the

geophysical features. Geochemical analyses are pending and the final interpretation of the IP data is

underway.

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%

-3-

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.
