ATEX Intersects 30 Metres of 4.40% CuEq in
Highest-Grade Porphyry Intersection at
Valeriano to Date
Extends High-Grade Porphyry Trend 200 Metres Along Strike
to the North and Trend Remains Open
Toronto, Ontario--(Newsfile Corp. - March 18, 2025) -
ATEX Resources Inc. (TSXV: ATX) (
"
ATEX
" or
the "
Company
") is pleased to provide an update on its Phase V program at the Valeriano Copper Gold
Project ("
Valeriano
" or the "
Project
"), located in the Atacama Region, Chile. The Company currently
has five diamond drill rigs operating, five holes completed and another five in progress. To date 9,675
metres of drilling has been completed in Phase V. ATEX is also pleased to announce the appointment
of Dr. Christine Rainaud as Exploration Director. Dr. Rainaud brings decades of senior mineral
exploration experience to the ATEX team, where she will play a key role in advancing exploration at the
Valeriano Project.
Highlights include:
Partial assays including
a high-grade intersection in ATXD25A of 30 metres ("m") grading
4.40% copper equivalent ("CuEq")
(2.21% Cu, 3.17 g/t Au, 15.1 g/t Ag and 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) from
1,892m downhole with results above and below this interval pending.
ATXD25A continued drilling from a depth of 1,454m, where it was paused at the end of
Phase IV, targeting the northern extension of the high-grade porphyry trend.
This represents the highest-grade and northernmost intersection within mineralized porphyry
to date, extending
the previously identified high-grade trend by 200m to a length of
~1,000m where it remains open.
A new high-grade, bornite bearing enrichment zone
was intersected with the hole
completed at 2,232m downhole,
achieving a new record hole length at Valeriano
and
ending in high grade mineralized porphyry.This intersection is 1,000m below the B2B zone
representing
a new exploration target that will be tested 200m up-dip in hole
ATXD25B.
The complete results for ATXD16B significantly increase the length of previously
reported intersections
i
to 232m of 1.00% CuEq
(0.75% Cu, 0.31 g/t Au, 1.2 g/t Ag and 88 g/t
Mo)
within a broader interval of 780m of 0.76% CuEq
(0.56% Cu, 0.23 g/t Au, 0.9 g/t Ag and
90 g/t Mo) from 1,044m downhole.
ATXD16B
extended the high-grade porphyry trend by approximately 120m to the southeast
where it remains open
.
ATXD23A intersected 152m of 2.12% CuEq
(1.52% Cu, 0.75 g/t Au, 4.9 g/t Ag, 161 g/t Mo)
within a broader interval of 342m of 1.52% CuEq
(1.05% Cu, 0.47 g/t Au, 3.0 g/t Ag, 326 g/t
Mo) from 1,226m downhole.
The complete results for ATXD23A have significantly increased the total mineralized
intersection to 1,220m of 0.91% CuEq
(0.66% Cu, 0.28 g/t Au, 1.9 g/t Ag, 130 g/t Mo)
from 822m downhole.
Two rigs
are currently dedicated to
defining the high-grade breccia B2B zone
with
two
others
focused on
infill drilling within the higher-grade Valeriano Porphyry
units. A
fifth rig
is drilling ATXD25B
, a follow-up hole to ATXD25A.
Dr. Christine Rainaud joins ATEX as the new Exploration Director, with over 25 years of
international exploration experience, most recently with BHP and formerly with Santiago
Metals, PanAust, Gold Fields, SRK and First Quantum Minerals.
"Valeriano keeps getting better with every hole in the Phase V program to date intersecting significant
high-grade mineralization and setting new records for the Project"
stated Ben Pullinger, President, and
CEO of ATEX.
"Hole 25A has successfully extended the high-grade porphyry trend to approximately
1,000m, where it remains open. With both the B2B zone and the Valeriano Porphyry delivering the
best drill results ever in Phase V, the Project continues to demonstrate its potential as an
internationally significant new copper-gold deposit. I am also excited to have Christine join our team;
her demonstrated expertise and leadership experience will be a valuable asset to our Company. I
also want to thank Dr. Owen Hatton for his contributions to the Valeriano Project, and I wish him all the
best in his future endeavors".
Dr. Christine Rainaud Joins ATEX as Exploration Director
Effective as of March 10, 2025, ATEX appointed Dr. Christine Rainaud as Exploration Director,
succeeding Dr. Owen Hatton who is stepping down from the role for personal reasons. Dr. Rainaud is a
senior geologist with a PhD in Economic Geology and over 25 years of international experience in
minerals exploration in both South America and Africa; most recently as Chile Exploration Manager with
BHP, and formerly with Santiago Metals, PanAust, Gold Fields, SRK and First Quantum Minerals. Her
experience includes managing projects from the exploration stage through to feasibility, multidisciplinary
team management, integration of high standards in safety, environment, inclusion, and team and culture
diversity. Dr. Hatton will continue to work with the team to ensure a smooth transition and operational
continuity and will work closely with Dr. Rainaud during the remainder of the Phase V program.
Phase V Update - Five Holes Completed, Five Holes Actively Drilling
To date, 9,675m have been drilled in the Phase V program with five holes completed including
ATXD23A, ATXD23B, ATXD16B, ATXD27A and ATXD25A and an additional five holes actively
drilling. Additional details on these holes are provided in the subsequent sections. Using directional
drilling techniques and drilling daughter holes, ATEX has saved approximately 7,000m of drilling,
compared to conventional drilling, resulting in a much more effective and efficient program. Daily drill
production continues to increase month on month, placing ATEX on track to achieve its targeted metres
for the overall Phase V program. Current and subsequent drill holes will continue to target infill, extension
(Figure 1 & 2), and high-grade breccia targets (Figure 1, 2 & 3).

B2B Exploration
ATXD27A (167°/-43°,
completed
at 2,148m) is a daughter hole from ATXD27 that was paused at
944 meters at the end of Phase IV. The target for ATXD27A was the northern extension of the
breccia corridor, 140m to the north of where the target was intersected in ATXD23A, and in an
area never tested before. ATXD27A drilled through host rock and from 1,043m to 1,397m and
entered a zone of alteration like that seen in drill holes ATXD23A and ATXD26. The hole ended in
early porphyry with chalcopyrite-bornite mineralization after intersecting the contact at 2,048m.
ATXD23B (140°/-50°,
completed
at 1,999m) is a daughter hole from ATXD23A stepping out
100m above ATXD23A, and is approximately 100m along strike, to the north, of ATXD26. The drill
hole targeted up-dip extensions, toward surface, of high-grade mineralization intersected in
ATXD23A. From 1,723m to 1,897m, this hole intersected a zone of alteration and mineralization
like that intersected 100m above in ATXD23A.
ATXD27B (149°/-73°,
ongoing
at 764m) is the second daughter hole from ATXD27. The hole is
currently drilling in mineralized host rock and will be targeting the B2B zone 150m to the northeast
of the high-grade breccia intersected in ATXD26 and ATXD23A.
ATXD29 (173°/-89°,
ongoing
at 223m) is a parent hole above the B2B zone. The hole is targeting
up-dip potential of the high-grade B2B zone, approximately 100m above the high-grade
intersections in ATXD26 and ATXD23A.
Valeriano Porphyry Exploration
ATXD25A (102°/-47°,
completed
at 2,232m) continued from where it was paused at the end of
Phase IV at a depth of 1,454m, targeting the northernmost extensions of the known mineralized
footprint. ATXD25A is a daughter hole to the north of ATXD25 (862.2m of 0.62% CuEq (0.42%
Cu, 0.27 g/t Au, 1.72 g/t Ag and 26 g/t Mo), including 114m of 0.88% CuEq (0.54% Cu, 0.48 g/t
Au, 2.95 g/t Ag and 6 g/t Mo), within a broader interval of 350.2m grading 0.75% CuEq (0.45% Cu,
0.42 g/t Au, 2.60 g/t Ag and 3 g/t Mo))
ii
and intersected the targeted mineralized porphyry at
1,771m to its final depth of 2,232m. A bornite bearing hydrothermal breccia zone was intersected
from 1,892m to 1,902m, and the hole was completed at 2,232m downhole achieving a new record
hole length at Valeriano. As this deeper hydrothermal breccia is directly below intersections in the
B2B breccias, it could possibly be a feeder zone to these intersections.
ATXD22C (257°/-74°,
ongoing
at 1,793m) is a daughter hole from ATXD22, designed to infill drill
and increase the confidence level of the Inferred Mineral Resource, drilling at nominal 150m
centres on previously defined high-grade zones within the existing porphyry footprint. The hole
intersected mineralized porphyry at 1,375m downhole, early porphyry from 1,580m to 1,666m, and
is continuing in mineralized porphyry. The hole will continue to an approximate depth of 2,000m.
ATXD25B (092°/-47°,
ongoing
at 1,542m) is a daughter hole from ATXD25 and a follow-up to
ATXD25A. The hole is designed to test mineralized intersections approximately 200m up-dip. The
drill hole is currently in host rock.
ATXD28 (293°/-76°,
ongoing
at 1,622m) is a parent hole from the same platform as ATXD19 and
is being drilled from surface. The hole is designed to infill drill on previously defined high-grade
zones within the existing porphyry footprint to increase confidence in the Inferred Mineral Resource,
drilling at nominal 150 metre centres. The drill hole intersected early porphyry from 1,246m to
1,276m and is currently drilling in mineralized porphyry.
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 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.
