ATEX Expands High-Grade Early Porphyry at

Valeriano Intersects 112 Metres of 1.42% CuEq

Within a Longer Interval of 852 M Grading

0.82% CuEq

Current drilling leads to updated interpretation of early

porphyry units highlighting potential for significant

expansion of high-grade system.

Toronto, Ontario--(Newsfile Corp. - February 22, 2024) -

ATEX Resources Inc. (TSXV: ATX)

("

ATEX

"

or the "

Company

") is pleased to announce complete assay results for drill holes ATXD16A and

ATXD17A, the second and third holes from its Phase IV drill campaign at the Valeriano Copper-Gold

Project ("

Valeriano

" or the "

Project

") located in Atacama Region, Chile

Highlights include

:

ATXD16A extends the high-grade porphyry ~100 meters to the southeast, with 852m

grading 0.82% CuEq (0.60% Cu, 0.28 g/t Au, 0.98 g/t Ag and 72 g/t Mo), including:

594m grading 0.92% CuEq (0.67% Cu, 0.32 g/t Au, 1.13 g/t Ag and 71 g/t Mo) within

Early Porphyry ("EP")

from 1,168m downhole.

and 112m of 1.42% CuEq (1.01% Cu, 0.57 g/t Au, 2.06 g/t Ag and 46 g/t Mo) from

1,616m downhole.

Merging the results from ATXD16A

(daughter hole) with the upper part of VAL16 (historical

hole) forms a

longer continuous interval of 1,226 metres grading 0.72% CuEq (0.52% Cu,

0.25 g/t Au, 0.91 g/t Ag and 68 g/t Mo

) starting at 576 metres downhole in VAL16 (Table 1).

ATXD17A intersected 924 metres grading 0.61% CuEq

(0.45% Cu, 0.17 g/t Au, 0.88 g/t Ag

and 99 g/t Mo) from 1,052 metres downhole including 98 m of 0.79% CuEq (0.56% Cu, 0.28 g/t Au

0.90 g/t Ag and 103 g/t Mo) related to EP mineralization.

Integrating the assay results and logging data from the first three holes of Phase IV with

geophysical data sets has led to the evolution of the EP model, indicating the potential for

a larger EP target within a NNW trending corridor (Figure 2).

Additionally, ATXD25 (currently drilling from the west (Figures 1&2)) has intersected EP at

1,550 metres downhole and approximately 200 metres west of the EP intersected in

ATXD11B (1,342.5m of 0.70% CuEq

(0.46% Cu, 0.31 g/t Au, 43 g/t Mo)

See Company news

dated March 30, 2023),

within the Western Trend. This adds further support to the evolving

concept of the NNW trending EP corridor.

ATEX currently has three rigs actively drilling on the project with holes ATXD26 and

ATXD17B are currently underway with the aim of testing for continuity of mineralized

porphyry between the currently modelled EP trends (Figure 2).

"These results are among the most exciting delivered to date by the Valeriano Project," stated Raymond

Jannas, President and CEO of ATEX. "We have delivered one of the highest grade and longest intervals

on the project in ATXD16A, which combined with the other holes from Phase IV, specifically ATXD25,

has highlighted the potential for a NNW trending EP corridor that likely hosts a larger EP target than

originally anticipated. This NNW conceptual trend remains open along strike and we are actively drilling

to infill gaps and expand the high-grade EP system."

formula stated below

Copper Equivalent (CuEq) is calculated using the formula CuEq % = Cu % + (6,481.488523 * Au g/t /10,000) +(94.6503085864* Ag g/t /10,000) +

(4.2328042328 * Mo g/t /10,000)

Results and Interpretation (Figure 2)

The results released today combined with existing and historical results indicate the potential for a larger

EP target within a NNW trending corridor. All EP and high-grade mineralization intersected by drilling to

date, falls within a corridor (Figure 2) with rough dimensions measuring 1.2 kilometres by 0.55

kilometres.

In addition, ATXD16A intersected EP in the gap between the Central and Eastern Trends confirming that

the two might be connected. The highest-grade interval intersected in hole ATXD17A was 0.79% CuEq

(0.56% Cu, 0.28 g/t Au 0.90 g/t Ag and 103 g/t Mo) over 98 metres (Table 1) and occurred directly

above the projected EP contact and within the gap between the Central and Western Trends.

Additionally, this intersection

occurs within the southern contact of conceptual NNW EP corridor. This

adds further support to potential for EP below this intersection. Lastly the intersection of EP within

potassic alteration in ATXD25, 200 metres to the west of the EP intersected in ATXD11B (1,342.5m of

0.70%

(2)

CuEq (0.46% Cu, 0.31 g/t Au, 43 g/t Mo) , and along the projection of the NNW trending

corridor is a significant development for the project, opening up a large EP target area to the west of

previous drilling. This NNW corridor is currently open along strike in both directions.

The most continuous high-grade intervals intersected on the Valeriano project to date have all been

within EP along what are believed to be discrete NE trending bodies. Drilling is currently underway to

target the gaps between these porphyry trends. Confirming the continuity of the EP within the gaps would

significantly increase the EP target size within the current mineralized footprint.

At the end of ATXD16A and ATXD17A, ATEX has completed approximately 6,500 metres of drilling in

Phase IV.

formula stated below

Copper Equivalent (CuEq) is calculated using the formula CuEq % = Cu % + (6,481.488523 * Au g/t /10,000) + (94.6503085864* Ag g/t /10,000) +

QAQC

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 La Serena. 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 and 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.
