ATEX Intersects 0.70% CuEq over 964m in a

200m Step-Out Along the Recently Discovered

High-Grade Western Porphyry Trend

Toronto, Ontario--(Newsfile Corp. - June 5, 2023) -

ATEX Resources Inc. (TSXV: ATX)

("

ATEX

" or the

"

Company

") is pleased to announce complete assay results for drill holes ATXD-22A and ATXD-23

from its Phase III drill campaign at the Valeriano Copper-Gold Project ("

Valeriano

" or the "

Project

")

located in Atacama Region, Chile.

Highlights include

:

ATXD-23 successfully extended the high-grade trend discovered in ATXD-11B,

intersecting 964 metres of 0.70% Copper Equivalent ("CuEq") (0.48% Cu, 0.24 g/t Au and

78 ppm Mo) (Figures 1, 2A & 2B) starting at 782 metres and including

:

602 metres of 0.80% CuEq (0.50% Cu, 0.37 g/t Au and 11 ppm Mo) from 1,130 metres,

and

120 metres of 0.90% CuEq (0.45% Cu, 0.54 g/t Au and 3ppm Mo) starting at 1,612

metres.

Additionally, ATXD-23 intersected 192 metres of 0.56% CuEq (0.24% Cu, 0.40 Au and

4ppm Mo) from 1,858 metres to the bottom of the hole, ending in mineralization.

The newly discovered Western Porphyry Trend now has a strike length of

approximately 700 metres and remains open. The Phase IV program will include

holes testing further extensions of this high-grade discovery

.

ATXD-22A (daughter hole), targeting the Eastern Porphyry Trend, intersected 546 metres of

0.45% CuEq (0.32% Cu, 0.08 g/t Au and 173 ppm Mo) from 921.4 meters downhole.

This mineralization continues from hole ATXD-22 (mother hole) grading 0.44% CuEq over

292 metres from 630 to 922 metres (0.31% Cu, 0.01 g/t Au and108 ppm Mo) (See March 30

release) above the kickoff point for ATXD-22A.

The final two holes of the program, ATXD-24 and ATXD-22B reached depths of 1,842.4 metres

and 1,615.05 metres respectively, with ATXD-24 paused in early porphyry within the Central Trend

and ATXD-22B in potassic altered, mineralized rock milled breccia "RMB" approaching the

Central Trend extension.

Both holes were paused due to earlier-than-expected adverse weather conditions.

Samples for the partial holes ATXD-24 and ATXD-22B have been sent to the lab with results

expected by late June or early July.

"We are incredibly happy and proud of how well our team and partners were able to execute throughout

this campaign," stated Raymond Jannas, President, and CEO of ATEX. "The Phase III program has

delivered on, and exceeded, its stated objectives, expanding the mineralized footprint, confirming

continuity along the Central High-Grade Trend, and testing new targets.

This has led to the discovery of a

new high-grade porphyry trend, the Western Trend where ATXD-11B, the highest-grade hole of the

Phase III was drilled. The overall size of the system has grown to 1,000 metres long by 1,000 metres

wide with a vertical extent of 1,000 metres. Within this footprint we have confirmed two high-grade

porphyry trends and have demonstrated their continuity with multiple drill intersections in both. We are

looking forward to completing a full review of these results and integrating them into our plans for Phase

IV, where we intend to continue demonstrating the enormous potential of the Valeriano Porphyry system.

We are also working towards an updated mineral resource estimate incorporating drilling up to and

including Phase III. We expect to update investors on this in the coming months."

The CuEq grade was calculated using a copper price of $2.60/lb, gold price of $1,450/oz and molybdenum price of $11.00/lb (all prices in US$).

Metal recoveries are not considered.

CuEq is calculated using the following formula - CuEq% = ((Cu%/100 * Cu $/tonne) + (Au g/t * Au $/gr.) +

(Mo%/100 * Mo $/tonne)) / Cu $/tonne.

2

Intervals are composited at a 0.40% CuEq cut-off and unless otherwise stated a maximum of 10 metres of internal dilution.

All intervals are reported as core lengths as the true lengths of the intervals are unknown at this time.

*

ATXD-22 Was initially reported by the Company on March 30, 2023.

**

ATXD-22A continues from mineralized interval in ATXD-22 from 630 metres to 922 metres.

Results

The intervals reported in ATXD-23 (Table 1) are interrupted by a 112-metre interval of intermineral

porphyry ("IMP") from 1,746 to 1,858 metres downhole. This interval of IMP grades 0.24% CuEq (0.11%

Cu, 0.16 g/t Au and 2 ppm Mo). ATXD-23 was drilled at a sub vertical angle (-83 degrees) and drilled

along the intermineral porphyry before exiting back into the early porphyry. Phase IV drill plans for the

Western Trend will include drill holes with intersection angles planned to drill across the target geology

and better test the width of the trend.

ATXD-22A (Daughter hole) commenced at a depth of 921.4 metres and was drilled southeast to test the

northern extension of the Eastern Trend. It was targeted to intersect this trend approximately 400 metres

north of VAL-16 (1,045 metres of 0.54% CuEq (0.39% Cu, 0.17 g/t Au & 54 ppm Mo)). The hole

commenced in mineralized RMB from its start point at 921 metres downhole in ATXD-22. Mineralization

and alteration in the hole decreased as the hole intersected a series of faults that ultimately cut-off

mineralization.

ATXD-24 was drilled to the southeast across the eastern contact of the Western trend and towards the

Central Trend. The hole intersected chalcopyrite bearing, mineralized RMB and a series of intermineral

porphyries starting from a depth of 580 metres to a depth of 1,350 metres. Several chalcopyrite bearing

hydrothermal breccia units were observed from 1,350 metres to 1,525 metres downhole. Strong

potassic alteration with intense stockwork and veining was intersected within the early porphyry from

1,525 metres to where the hole was paused at 1,842.4 metres. Assay results from ATXD-24 are

expected in late June or early July.

ATXD-22B (daughter hole), targeting the Central High-Grade Trend extension, commenced at a depth of

444 metres downhole from ATXD-22(mother hole). The hole intersected chalcopyrite bearing argillic

altered RMB from 595 metres to a depth of 1,100 metres. From 1,100 metres, to where the hole was

paused due to weather conditions, potassic altered chalcopyrite bearing RMB was intersected, including

zones of veining with visible chalcopyrite and bornite mineralization. The hole has been left in a condition

to be re-entered and completed, as an option in Phase IV, and results are expected by late June or early

July.

The Phase III campaign commenced in October 2022 and has been completed in late May 2023.

In total

12,513 metres of drilling were completed in eight drill holes including four holes from surface, and four

daughter holes drilled from existing holes. A summary of results for phase III is presented in Table 2.

There are two holes still to be reported from Phase III, ATXD-24 and ATXD-22B which are expected to

be announced in late June or early July.

Phase III achieved a series of execution records for the project including completing the deepest hole to

date at a depth of 2,190.5 metres (ATXD-11B) as well as achieving a 100% completion rate on drill

holes. Additionally, the utilization of directional drilling in Phase III resulted in a saving of ~3,000 metres

of drilling from surface. Phase IV, which will follow up on the success achieved in Phase III, is expected to

commence in October 2023.

Outlook

Final assay results for the remaining holes of the Phase III drill program are expected by the end of June

or early July. The Company intends to use these the Phase III results and data to update the copper-gold

mineral resource statement for the Valeriano Project and file an updated NI-43 101 compliant technical

report. Additionally, metallurgical test work using core from the Phase III program is being undertaken by

Atex in conjunction with Libertas Metallurgy and Base Met Labs of Kamloops BC.

This work is expected

to be completed in Q3.

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 the 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.

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. 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 (Filo Mining),

Josemaria (Lundin Mining), Los Helados (NGEX Minerals/JX Nippon), La Fortuna (Teck

Resources/Newmont) and El Encierro (Antofagasta/Barrick Gold).

Valeriano hosts a large copper gold porphyry deposit overlain by a near surface oxidized epithermal

gold deposit. In 2022, ATEX completed the Company's first limited drill test of the copper gold porphyry

system that is now being followed up with campaign of directional drilling to extend the high-grade trend,

test new targets and expand the mineralized envelope.
