ATEX Announces Additional High-Grade

Assays from the B2B Zone Significantly

Increasing Size of Previously Announced

Interval

New results from ATXD26B deliver improved size and grade of

186 meters of 2.13% CuEq including 88 Meters of 2.70% CuEq

with results for 400 meters still pending

Toronto, Ontario--(Newsfile Corp. - January 13, 2026) -

ATEX Resources Inc. (TSXV: ATX) (OTCQB:

ATXRF)

("

ATEX

" or the "

Company

") is pleased to announce a second set of assay results for Phase

VI drill hole ATXD26B, the second hole from the current campaign at the Valeriano Copper-Gold Project

("

Valeriano

" or the "

Project

") located in Atacama Region, Chile. Drilling commenced in September

with six rigs operational on site and has already achieved over half of the 25,000 meters guided for

Phase VI. As noted in prior releases, while the drill program is advancing ahead of schedule, assay

laboratory turnaround times continue to be longer than expected due to elevated seasonal demand

across the industry.

"The continuation of drill results from ATXD26B has improved both the thickness and grades of the

B2B breccia, reinforcing the continuity and growth potential of this high-grade zone,"

commented Ben

Pullinger, President and CEO of ATEX.

"The robustness of this high-grade system continues to be

shown through repeated intersections of consistent, high-grade mineralization, underscoring its

potential to support further resource growth. We now see a zone with approximate dimensions of 400

meters of strike, up to 200 meters in horizontal width and a vertical extent of 500 to 600 meters. We

see potential to further add high-grade tonnes in the porphyry and other breccia targets at Valeriano.

Our focus in 2026 is to aggressively advance these targets."

Highlights include:

ATXD26B

, targeting the

B2B Zone

reported an additional 224 meters of assays, resulting in an

intercept of

88 metres (

) of 2.70% copper equivalent (

(1.32% Cu, 0.72 g/t Au) and

448m

(0.93% Cu, 0.51 g/t Au).

Increase of 34m including 8% higher CuEq grade

224m of 1.52% CuEq (1.02% Cu, 0.49 g/t Au).

Quality Control & Quality Assurance

Drill holes are collared with a PQ drill bit, reduced to HQ and, sequentially, to NQ as the drill holes

progressed deeper. Drill core produced by the drill rigs was extracted from the core tubes by the drill

contractor under the supervision of ATEX employees, marked for consistent orientation and placed in

core boxes with appropriate depth markers added. Full core boxes were then sealed before being

transported by ATEX personnel to the Valeriano field camp. Core at the field camp is processed, quick

logged, checked for recovery, photographed, and marked for specific gravity, geotechnical studies and

for assays. From camp, the core is transferred to a secure core-cutting facility in Vallenar, operated by

IMG, a third-party consultant. Here, the core trays are weighed before being cut using a diamond saw

under ATEX personnel oversight. ATEX geologists working at this facility double-check the selected

two-metre sample intervals, placing the samples in seal bags and ensuring that the same side of the

core is consistently sampled. Reference numbers are assigned to each sample and each sample is

weighed. The core trays with the remaining half-core are weighed and photographed. Additionally, core

logs are updated, and specific gravity and geotechnical samples are collected. The remaining core is

stored in racks at the Company's secure facility in Vallenar.

From Vallenar samples are sent to an ALS preparation facility in Copiapo. ALS is an accredited

laboratory which is independent of the Company. The prepared samples were sent to the ALS assay

laboratories in either Santiago, Chile or Lima, Peru for gold (Au-AA24), copper (Cu-AA62), molybdenum

(Mo-AA62) and silver (Ag-AA62) assays as well as and multi-element ICP (ME-MS61) analysis. No data

quality problems were indicated by the QA/QC program.

About ATEX

ATEX is exploring the Valeriano Copper-Gold Project which is located within the emerging copper gold

porphyry mineral belt linking the prolific El Indio High-Sulphidation Belt to the south with the Maricunga

Gold Porphyry Belt to the north, located in the Atacama Region, Chile. This emerging belt, informally

referred to as the Link Belt, hosts several copper gold porphyry deposits at various stages of

development including, Filo del Sol (Lundin Mining/BHP), Josemaria (Lundin Mining/BHP), Lunahausi

(NGEx Minerals), La Fortuna (Teck Resources/Newmont) and El Encierro (Antofagasta/Barrick).

Valeriano hosts a large, high-grade, copper-gold porphyry Mineral Resource: an Indicated Resource of

475 Mt at 0.88% CuEq (0.58% Cu, 0.25 g/t Au, 1.39 g/t Ag and 70.4 g/t Mo) at a cutoff grade of 0.35%

Cu, and an Inferred resource of 1,511 Mt at 0.75% CuEq (0.50% Cu, 0.20 g/t Au, 1.16 g/t Ag and 70.6

g/t Mo) at a cut-off grade of 0.35% Cu, as reported on September 23, 2025.
