CopperEx Identifies Second Parallel Gold
Trend Adjacent to the 7-Kilometer-Long ADLP
Trend Returning 22 meters @ 0.59 g/t Gold at
Sorpresa with Gold Mineralization over 4.9
Kilometers
Vancouver, British Columbia--(Newsfile Corp. - February 28, 2024) - CopperEx Resources Corp.
(TSXV: CUEX) (the "Company" or "CopperEx") provides results from the recently completed surface
trenching (and rock chip sampling) program centered on the Sorpresa Trend within the
Franja del Oro
gold target which now consists of at least two parallel gold trends (Agua de la Piedra "ADLP" and
Sorpresa) which is defined by approximately 15 kilometers of discontinuously outcropping, gold-bearing
clastic sedimentary rocks located in the northwest portion of the 23 by 13-kilometer (20,800 hectare)
Exploradora Norte Project located in Northern Chile (Figure 1).

CopperEx's Trenching program defined gold and arsenic anomalism over 4.9 kilometers in the
Sorpresa Trend which is part of the Companies broader Franja del Oro gold target.
Gold mineralization in the Sorpresa Trend is oxidized and exposed at surface and has not
previously been drilled.
The Sorpresa Trend will be tested by 3 holes drilled as part of an upcoming drill campaign focused
on the Franja del Oro gold target.
Dave Prins, President & CEO of CopperEx
stated, "
The results from the surface trenching along the
Sorpresa Trend significantly increase the Franja del Oro target potential to host a large bulk tonnage
oxidized gold resource.
This work has established that the Franja del Oro target contains multiple
north-south trending parallel zones of gold mineralization with inadequately tested depth potential.
We
are scheduled to commence drilling this extremely compelling surface gold target, "Franja de Oro", in
the very near future.
"
2023/2024 Trenching Program
A total of 463 surface rock geochemical samples were collected from 12 trenches and outboard surface
rock sampling along the Sorpresa Trend (Figure 2; Tables 1-4).
The objective of the trenching campaign
was to test the gold grade and continuity of the Sorpresa Trend and to delineate the extent of gold and
arsenic geochemical anomalism.
The Sorpresa Trend trenching campaign tested the potential of mid Jurassic fossiliferous limestones,
calcareous sandstones, and siltstones and associated stocks and dikes (dacite, diorite and quartz
diorite) to host bulk tonnage oxide gold mineralization.
The sedimentary rocks at Sorpresa are folded
into a series of anticlinal and synclinal geometries that have north-south trending axes. Gold
mineralization is associated with advanced argillic alteration, iron oxides including jarosite and goethite,
black and white calcite stockwork veinlets (distal) and quartz and barite veinlets (proximal) and locally
vuggy silica.
Trench sampling and surface rock sample results at Sorpresa returned anomalous gold and arsenic
geochemistry over a total distance of 4.9 kilometers and identified significant mineralized intercepts in
trenches ST-01-E, ST-01-W, ST-03 and ST-04 (Figures 2-4; Tables 1-2).
The variability in gold grades
across the trenches suggests that the zone may be offset vertically and laterally across the trend.
This
apparent offset may explain the variability in gold and arsenic values (north-south) because of the
juxtaposition of different erosional levels of the system (Figure 2)
Previous Drilling and Trenching at Franja del Oro (ADLP and Sorpresa Trends)
Historic drilling in this area by Aur Resources / Arizona Star returned the following results
(1)
:
AP-01: 65m @ 1.59gpt (from surface)
AP-02:
60m @ 2.02gpt (starting at 59m)
AP-10:
24m @ 1.22gpt (starting at 94m)
The historical drill results are from the adjacent north-south trending ADLP Zone located approximately
1,300 meters west of the Sorpresa Trend.
These results demonstrate that surface gold mineralization
exposed at surface within at Franja del Oro (e.g., ADLP and Sorpresa) has the potential for significant
depth continuity with robust grades.
In addition, CopperEx conducted trenching and sampling in 2023 at the northern extent of the Sorpresa
Trend and obtained:
43.4m @ 0.98gpt Au including 22.0 meters @ 1.40 g/t Au and 12.0 meters @ 1.72 g/t Au

QA/QC Methods and Procedures.
All rock samples have been sent to AAA CHILE Ltd. ("AAA") in Santiago Chile, for preparation and
analysis. AAA meets all requirements of International Standards ISO/IEC 17025:2005 and ISO
9001:2015 for analytical procedures.
Trench samples were collected on 2.5 meter centers, and sample
mid-points were marked with metal tags (including sample identification) and assigned a GPS location.
Samples were analyzed using AAA's Fire Assay Fusion method (Au-AA24) with an AA finish for gold
and by a 48-element four acid digest ICP-AES analysis (MS61) with additional analysis for Ore Grade
Elements (ME-OG62) and Ore Grade Cu (Cu-OG62). Results are be reported in parts per million (ppm)
and converted to percent (%), or grams per tonne (g/t) where applicable. In addition to AAA Laboratory
quality assurance- quality control (QA/QC) protocols, CopperEx implements an internal QA/QC program
that includes inserting fine and coarse blank samples (3.3%), inserting OREAS series standards (total
2.3%, including of OREAS 153, OREAS 501b, OREAS 523, OREAS 606, OREAS 607, OREAS 608
and OREAS 620) and duplicate samples in the field and laboratory (2.0%), obtaining a total of 7.7%
laboratory control.
All scientific and technical information in this news release has been approved by
Daniel MacNeil,
PGeo,
Technical Advisor to the Company. Mr. MacNeil is a qualified person for the purposes of NI 43-
101.
Some of the drilling and trench results disclosed in this news release relates to historical results on the
Exploradora Norte Property. CopperEx has not undertaken any independent investigation of the historic
sampling, nor has it independently analyzed the results of the historical exploration work to verify the
results. CopperEx considers these historical drill results relevant as the Company is using this data as a
guide to plan exploration programs. The Company's current and future exploration work includes
verification of the historical data through drilling.
