CopperEx Resources 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, Feb 28, 2024 - CopperEx Resources Corporation (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 Au3,4

About CopperEx Resources Corp.

CopperEx is a copper and gold focused exploration company with three porphyry and porphyry related gold and copper projects located in Chile and Peru in established mineral belts near producing mines. The Company's Flagship Property, Exploradora Norte, located in Northern Chile, has multiple high quality drill ready targets. At Exploradora Norte, CopperEx has the option to earn 65% and a Preferred Option for an additional 35% with no attached royalty.

In addition to the Exploradora Norte property, CopperEx owns 100% of its Kio Buggy (Northern Chile) and La Rica (Apurimac province Peru) properties, also with no attached royalties. The CopperEx Exploradora Norte property is immediately adjacent to the north and east of the Codelco Exploradora property which hosts a resource estimated by Codelco to contain 190-280 Mt @ 0.40% Cu.(2)

The Company's priority is to drill the advanced exploration Franja Del Oro Target at Exploradora Norte and includes the Sorpresa and Agua de la Piedra (ADLP) sub sectors, and the surrounding favorable host rocks which remain significantly underexplored.


Exploradora Norte Advanced Exploration Targets.

- The Franja del Oro target contains sediment hosted gold mineralization with associated replacement textures and alteration consistent with epithermal gold deposits that form distal to a porphyry copper-gold system (Figure 2). Gold mineralization at Franja del Oro is widespread, with values up to 3.97 ppm Au at ADLP3,4 (Trench AT-04; Figure 3) and values up to 4.57 ppm Au at Sorpresa3,4 (Au-Creek-Trench; Figure 4). The Franja del Oro target hosts multiple parallel, north trending stratigraphically and structurally controlled mineralized zones (Figure 2). CopperEx has conducted extensive exploration along 4-kilometer-long north-south trending segments of the high priority Sorpresa and Agua de la Piedra ("ADLP") zones to assess surface gold grades and continuity (along strike) and to define individual drill targets (Figures 2-4). CopperEx has identified gold mineralization over approximately 7 kilometers on the ADLP system (surface rock geochemical results). CopperEx leveraged the correlation between gold and arsenic to expand the geochemical footprint of the Franja del Oro target using Portable XRF technology to approximately 15 kilometers (and remains open).

- Peuco - Porphyry Copper Gold target: Geochemical and geophysical anomalies spatially associated with tourmaline breccia bodies with values up to 1.69 ppm Au3,4 (Figure 2). Copper rock surface samples range from laboratory below detection to 1,021 ppm3,4. Breccias consist of potassically altered porphyry clasts in quartz-tourmaline matrix associated with peripheral polymetallic veins and skarn alteration.

- Florencia Copper Gold target - Centered on a NW-SE trending structural corridor extending to the Exploradora porphyry Cu deposit (Codelco) ~5 km to the NW. IP Geophysical features (resistivity and chargeability) suggest the potential for porphyry style copper-gold mineralization at depth. Epithermal style quartz veins and breccia, alteration, and geochemical anomalism exist at surface (up to 1.02 ppm Au & 1,320 ppm Cu3,4; see Figure 2).
