ATEX Completes Phase V Program Ending in
High-Grade B2B Mineralization - Strategic
Objectives Achieved with Resource Update
Expected in 2H 2025
Phase VI to Target New High-Grade Breccia and Regional
Targets
Toronto, Ontario--(Newsfile Corp. - July 30, 2025) -
ATEX Resources Inc.
(
TSXV: ATX
) ("
ATEX
" or
the "
Company
") is pleased to announce assay results for ATXD25C, ATXD27B and ATXD28,
representing the final three drill holes in the Phase V drill program, concluding the most successful
campaign at the Valeriano Copper-Gold Project ("
Valeriano
" or the "
Project
"), located in the Atacama
Region, Chile. ATEX plans to begin its Phase VI drill program as early as September with more details
to be provided closer to program commencement.
"The results from our Phase V drill program represent the best we've ever seen at Valeriano,
delivering exceptional copper and gold grades and confirming the scale and continuity of the system,"
Ben Pullinger, President and CEO, commented.
"These results not only validate and improve our
geological model but also set a strong foundation for the upcoming Phase VI program, which is
currently in progress with an expected start in September allowing for an extended drill season and
increased metres completion. A key priority will be defining the geometry and understanding the
structural controls of the high-grade breccias, while also stepping out to test new, high-potential targets
supported by our evolving geological model. We plan to release an updated Mineral Resource
Estimate later this year which will encompass drilling from Phase IV (totaling ~12,000m) and Phase V
(totaling ~16,600m) which delivered stronger results than the previous drill campaigns. The update will
also incorporate improved metallurgical recoveries as outlined in our second metallurgical program
i
.
ATEX is well positioned to build on the Phase V momentum and unlock further upside as we continue
to advance and de-risk the project."
Highlights include:
ATXD25C
, testing a potential link between the B2B breccia and the high-grade bornite zone in
hole ATXD25A, intersected
138 metres (
"
m
"
) of 0.75% copper equivalent (
"
CuEq
"
)
(0.58%
Cu, 0.19 g/t Au, 0.9 g/t Ag, 67 g/t Mo) starting at 1,394m downhole and
8m of 2.26% CuEq
(1.69% Cu, 0.80 g/t Au, 5.0 g/t Ag and 30 g/t Mo) starting at 1,558m downhole.
The hole ended in the B2B Zone,
intersecting grades of over 2% CuEq and will be
followed up in Phase VI.
ATXD27B
, targeting the B2B Zone from the northwest, intersected
34m grading 0.95% CuEq
(0.69% Cu, 0.35 g/t Au, 1.1 g/t Ag, 55 g/t Mo) within a broader interval of
458m of 0.65% CuEq
(0.50% Cu, 0.14 g/t Au, 0.8 g/t Ag, 130 g/t Mo) from 1,174m downhole.
The hole was
paused in well mineralized wall rock
and will be completed as part of the
Phase VI program.
ATXD28A
, testing Early Porphyry as part of the infill program, intersected
96m of 0.93% CuEq
(0.68% Cu, 0.29 g/t Au, 1.5 g/t Ag, 107 g/t Mo) from 1,106m downhole, and
172m of
0.89% CuEq
(0.68% Cu, 0.24 g/t Au, 1.4 g/t Ag and 78 g/t Mo) from 1,228m downhole. Both intervals are
included within a broader interval of
516m of 0.79% CuEq
(0.59% Cu, 0.23 g/t Au, 1.3 g/t Ag and
85 g/t Mo) starting at 970m downhole.
The hole demonstrated
another extensive well-mineralized interval
that reaffirms the
continuity and connectivity of the Valeriano Porphyry system.
ATEX is also pleased to announce it has received an additional CAD$9.75 million in total
proceeds from the exercise of the remaining 7.5 million common share purchase warrants
("Warrants") which expired in July 2025, priced at CAD$1.30, further strengthening the Company's
balance sheet.
These Warrants have been exercised by long-term core ATEX
shareholders
.
Phase V Achieves Stated Objectives:
Strategic goals were successfully met
including to:
Delineate the high-grade B2B breccia zone located atop the Valeriano Porphyry;
Extend the high-grade porphyry trend which remains open; and
Test the broader porphyry footprint through infill and step-out drilling with limits still unknown.
16,600 metres of diamond drilling completed,
saving 9,200 metres
by utilizing
innovative
directional drilling technology
.
Confirmed and significantly expanded the high-grade B2B Zone, from a single intercept
at the end of Phase IV to a strike length of approximately 500m supported by
multiple
significant high-grade intercepts at the end of Phase V.
Traced the B2B Zone approximately 200m closer to surface,
now at a depth of roughly
400m
below the valley floor
.
Defined a
core of over 2% CuEq mineralization within the B2B Zone that remains open for
expansion
that will be a
priority target in the Phase VI program
.
Analysis of data and geological information collected through the B2B discovery has generated
multiple other B2B-style targets to be tested
in future exploration programs.
The
high-grade porphyry trend grading over 0.8% CuEq
, within the Valeriano Porphyry was
extended by over 200m to approximately 1 kilometre where it still remains open
to the
north-northwest and to the southeast.
Outlook - Phase VI Drill Program to Commence Shortly with Updated MRE in 2H 2025
Phase VI program planning underway and expected to commence in September
.
Four strategic objectives
in Phase VI will include:
1
.
Focus on further delineation and growth of the high-grade B2B Zone;
2
.
Explore for and test other high-grade breccia targets to the north, and new regional targets;
3
.
Continue expanding the Valeriano Porphyry system where system limits are still unknown;
and
4
.
Continue project derisking through ongoing baseline environmental studies and monitoring,
early stage engineering studies, including hydrogeology and geotechnical scopes and
advancing permitting for future drill campaigns.
Updated Mineral Resource Estimate ("MRE") expected in the second half of 2025.

Phase V Drill Results - Final Three Assays
A discussion of holes ATXD27B, ATXD25C, and ATXD28A is provided below along with an overview of
completed drill holes, as well as those being drilled up until the Phase V demobilization.
B2B Zone Exploration
ATXD27B
(paused at 1,632m) is the second daughter hole from ATXD27. The hole was
suspended in mineralized wall rock and was targeting the B2B Zone 150m to the northeast of the
high-grade breccia intersected in ATXD26 and ATXD23A. The hole will be completed as part of
Phase VI.
34m of 0.95% CuEq
(0.69% Cu, 0.35 g/t Au, 1.1 g/t Ag, 55 g/t Mo) from 1,540m downhole
is associated with Rock Milled Breccia ("RMB") and chalcopyrite mineralization.
The broader interval of
458m of 0.65% CuEq
(0.50% Cu, 0.14 g/t Au, 0.8 g/t Ag, 130 g/t
Mo) intersected mineralized wall rock from 1,174m to 1,322m, chalcopyrite mineralized RMB
to 1,590m, followed by well-mineralized wall rock to the end of the hole, demonstrating strong
mineralization in the host rock.
The drill hole will be completed as part of the Phase VI program.
ATXD25C
(paused at 1,566m) is a daughter hole from ATXD25A designed to test the potential
link between the B2B breccia and the high-grade bornite zone intersected in ATXD25A.
230m of 0.68% CuEq
(0.52% Cu, 0.16 g/t Au, 0.9 g/t Ag, 99 g/t Mo) from 1,302m downhole
intersected chalcopyrite-mineralized RMB, consistent with the northern trend of the system.
At the bottom of the hole,
8m of 2.26% CuEq
(1.69% Cu, 0.80 g/t Au, 5.0 g/t Ag, 30 g/t)
intersected RMB mineralized with chalcopyrite and enargite in faulted zone.
Valeriano Porphyry Exploration
ATXD28A
(paused at 1,918m) is a daughter hole from ATXD28 and is designed to test Early
Porphyry mineralization on nominal 150m centres as part of the infill program.
96m of 0.93% CuEq
(0.68% Cu, 0.29 g/t Au, 1.5 g/t Ag, 107 g/t Mo) from 1,106m
downhole, and
172m of 0.89% CuEq
(0.68% Cu, 0.24 g/t Au, 1.4 g/t Ag, 78 g/t Mo) from
1,228m downhole intersected chalcopyrite-mineralized RMB above mineralized Intermineral
Porphyry.
Both intervals described above fall within a broader interval
of 516m of 0.79% CuEq
(0.59% Cu,0.23 g/t Au, 1.3 g/t Ag, 85 g/t Mo) of RMB from 970m to 1,400m downhole,
followed by chalcopyrite-mineralized Intermineral Porphyry.
The presence of RMB and Intermineral Porphyry supports the interpretation of a mineralized
system in this unexplored portion of the Project.
Phase V - The Largest and Most Successful Exploration Program at Valeriano to Date
The Program completed approximately 16,600 metres of directional diamond drilling compared to
approximately 12,000m achieved in Phase IV, an increase of about 4,600m. Using directional drilling
techniques, ATEX has saved approximately 9,200m of drilling compared to conventional drilling
methods enhancing the overall effectiveness of the program.
The recently completed drill program deployed five rigs, an increase from the three utilized during Phase
IV. Phase V confirmed and significantly expanded the high-grade B2B Zone, which was previously
identified from a single intercept in the final hole of Phase IV. The B2B Zone now extends over a strike
length of roughly 500m and has been delineated approximately 200m closer to surface, with its upper
contact positioned at a depth of 400m below the valley floor. Additionally, the high-grade porphyry trend,
defined by intervals grading greater than 0.8% CuEq within the Valeriano Porphyry, was extended by
more than 200m and now spans approximately one kilometre in length. This mineralized corridor
remains open along strike to the north-northwest and southeast.
Nine holes were completed in Phase V (ATXD16B, 22C, 23A, 23B, 25A, 25B, 27A, 28, and 28A) and
four partial holes (ATXD22D, 25C, 27B, and 29A) will be completed as part of the Phase VI program.
ATEX's exploration objectives for Phase V were focused on three priorities:
1
.
B2B Breccia Zone
- a high-grade breccia body with copper-gold mineralization, situated
approximately 600 metres above the high-grade porphyry corridor. This zone is currently being
delineated for geometry and scale.
2
.
High-Grade Porphyry Trend
- a continuous high-grade (0.8% CuEq) trend of bornite and
chalcopyrite-bearing mineralization within the Porphyry footprint measuring approximately 1,000m
along strike, and remains open to the north-northwest.
3
.
Broader Porphyry Footprint
- testing the large mineralized system encompassing both Early
and Inter-mineral porphyry phases, tested through infill and step-out drilling with limits still not
known.
The Phase V drill campaign yielded the most significant intercepts in ATEX's exploration history,
providing a robust foundation for targeted follow-up drilling in the upcoming Phase VI program. Standout
drill holes included the following (additional details provided in Table 2):
ATXD23A (February 24, 2025)
- Delivered a record-breaking intercept of
152m at 2.12% CuEq
(1.52% Cu, 0.75 g/t Au, 0.8 g/t Ag, 41 g/t Mo) within a broader interval of
342m of 1.52% CuEq
(1.05% Cu, 0.47 g/t Au, 1.2 g/t Ag, 272 g/t Mo)
, representing a 130m extension to the high-grade
breccia mineralization intersected in ATXD26
ii
.
ATXD25A (April 22, 2025)
- Intersected
16m of 6.36% CuEq
(3.04% Cu, 4.82 g/t Au, 21.1 g/t
Ag, 5 g/t Mo), within a broader interval of
30m of 4.40% CuEq
(2.21% Cu, 3.17 g/t Au, 15.1 g/t
Ag, 3 g/t Mo)
within a broader interval of 108m of 1.69% CuEq
(0.87% Cu, 1.18 g/t Au, 5.5 g/t
Ag and 9 g/t Mo), the highest-grade and northernmost intersection encountered in mineralized
porphyry, extending the high-grade trend by 200m to a length of approximately 1,000m and
remaining open to the north.
ATXD28 (June 2, 2025)
- A broad intercept of
1,090m at 0.81% CuEq
(0.56% Cu, 0.32 g/t Au,
1.8 g/t Ag, 57 g/t Mo) highlighted another significant and continuous well-mineralized interval.
ATXD29A (June 9, 2025)
- Targeting the high-grade B2B Zone, intersected
36m grading 3.05%
CuEq
(2.10% Cu, 1.02 g/t Au, 6.2 g/t Ag, 542 g/t Mo) within an interval of
126m of 2.04% CuEq
(1.47% Cu, 0.67 g/t Au, 3.7 g/t Ag, 252 g/t Mo) within a broader interval of
536m of 1.04% CuEq
(0.75% Cu, 0.28 g/t Au, 1.7 g/t Ag, 225 g/t Mo), confirming consistency and continuity of
mineralization with a grade over 2.0% CuEq.

Outlook - Phase VI Planning Underway
Following the record setting results achieved in Phase V on the Valeriano Project, Phase VI is
anticipated to commence in September. This program will aim to focus on further delineation and growth
of the high-grade B2B Zone; explore for and test other high-grade breccia targets to the north, and new
regional targets; continue expanding the Valeriano Porphyry system where system limits are still
unknown; and continue project derisking through ongoing baseline environmental studies and
monitoring, early stage engineering studies, including hydrogeology and geotechnical scopes and
advancing permitting for future drill campaigns (see Figure 1). Additional information will be provided
closer to commencement of the drilling campaign.
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 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.
