CopperEx Resources Corp. (TSX-V: CUEX) announces results from a 7,902-meter surface trenching program at the Company’s flagship Exploradora Norte Project. A total of 29 trenches and 28 test pits were excavated at the Agua de la Piedra (6,650 meters ) and Sorpresa (1,252 meters) prospects at Franja del Oro Target, part of a 15-kilometer-long gold enrichment trend that represents one of several| gold-copper enriched magmatic hydrothermal centers on the 20,800-hectare Exploradora Norte Project, located in the Eocene-Oligocene porphyry-epithermal belt in Northern Chile (Figure 1, Tables 1 and 2).

Dave Prins, President & CEO of CopperEx stated, “The results of the trenching campaign at Exploradora Norte more accurately define the distribution of gold mineralization at ADLP and Sorpresa which will be used to guide upcoming diamond drilling designed to expand the gold mineralized footprint defined by CopperEx’s highly successfully inaugural RC drilling program completed earlier this year.”

Highlights:

• CopperEx completed 7,902 meters of Trenching at Sorpresa and ADLP as part of a larger investigation into the 15 x 3-kilometer Franja del Oro target located on the northwestern quadrant of the Exploradora Norte Property.
• The distribution of favorable host rocks, alteration and geochemical anomalism at surface supports continued drilling within and external to the high-priority ADLP and Sorpresa zones

CopperEx has an Option Agreement for the 20,800-hectare Exploradora Norte property, to earn a 65% ownership interest, with a preferred option to earn an additional 35%. The property is located along the prolific West Fissure fault system in northern Chile, north of El Salvador and south of Escondida at 3,400 meters above sea level in the Chilean pre-cordillera. The property has a year-round operating climate with good access.

Trenching Program

The surface trenching program was designed to follow up the CopperEx highly successful inaugural 2024 RC drill program at the Franja del Oro target which focused on the ADLP and Sorpresa zones which are parallel altered and gold mineralized zones that form a trend measuring 15 kilometers by 3 kilometers (Figure 1, Tables 1-3). Surface trenching was undertaken with a Hyundai Robex 330 excavator. The campaign was extended as several of the initial trenches yielded open ended gold zones. The program commenced June 14^th 2024, and ending on August 31^st 2024

The objectives of the trenching were to 1) map the surface expression of Sorpresa and ADLP gold mineralization, 2) define and geochemically characterize alteration features north of ADLP and Sorpresa at the Oreganito zone and, 3) place all three zones in a 3-dimensional geological framework to establish depth to gold mineralization from surface. A total of 807 samples were collected in 29 trenches and 28 test pits. The average sample length is 2.5 meters (along the trench). Geochemical results for the 2024 trenching are shown on Figure 1 and Tables 1 and 2.

Sorpresa Zone (Franja del Oro Target)

Table 1. Trenching intercepts from the Sorpresa Zone, Franja del Oro Target, Exploradora Norte Project, Chile¹.

A total of 7 trenches and 3 test pits were excavated at Sorpresa to delineate the surface expression of gold mineralization and related alteration of favorable host rocks (Figure 2). Significant gold mineralization was intersected in trenches ST-10 and ST-13 (Table 1; Figures 1 and 2). The results of the latest trenching campaign will be used to plan follow up diamond drilling. Trenching at Sorpresa Zone further delineated, grade and continuity of the zone of mid Jurassic fossiliferous limestones, calcareous sandstones, and siltstones and associated stocks and dikes (dacite, diorite and quartz diorite) that contain vein and disseminated oxide gold mineralization. The sedimentary rocks at Sorpresa are folded into a series of anticlinal and synclinal fold geometries that have north-south trending axes. Gold mineralization is associated with clay and silica alteration, iron oxides including jarosite and goethite, black and white calcite stockwork veinlets (distal) and quartz and barite veinlets (proximal) and focused in decalcified limestones and limey sandstones within the Jurassic host rocks.

ADLP Zone (Franja del Oro Target)

Table 2. Trench intercepts from the ADLP Zone, Franja del Oro Target, Exploradora Norte Project, Chile¹.

A total of 22 trenches and 25 test pits were excavated at ADLP to define the surface trace of gold mineralization and to test alteration in favorable host rocks previously mapped at surface (Figure 1 and Table 2). Significant gold mineralization was intersected in trenches AT-19 EAST, AT-20,AT-21 and AT-25 (Table 2, Figures 1 and Table 2). The Agua de la Piedra Target is centered on mid Jurassic Montandon and Asientos formation bedded fossiliferous limestones, calcareous sandstones and siltstones (locally bituminous) which are unconformably overlain by Paleocene volcanics (Cerro Nevado sequence) and intruded by small stocks and dikes related to the Eocene Quebrada Oreganito diorites. ADLP is prospective for carbonate replacement gold mineralization, disseminated and structurally controlled gold mineralization associated with volcanic rocks, and breccias (basal flows) at or near the angular unconformity with Jurassic sedimentary host rocks. In addition, ADLP has the potential for high grade vertical feeder structures (epithermal) which cut the sedimentary and volcanic rocks and has the potential for porphyry mineralization at depth.

Oreganito Zone (Franja del Oro Target)

The Oreganito Zone is located immediately North of ADLP across the Oreganito Fault Zone. Favorable host rocks and alteration at Surface. No significant mineralization was obtained from trenching in the Organito Zone. Gold mineralization at Franja del Oro is influenced by elevation and the despite the lack of anomalous geochemistry at surface the system may be mineralized at depth.

Geological, Lithological, Alteration and Numerical Models

CopperEx has now incorporated all historic data including the recently completed surface trenching program designed to follow up the Company’s highly successful inaugural 2024 RC drill program at the Franja del Oro target, generating geological, lithological, alteration and geochemical models for the ADLP and Sorpresa targets. These models have now been used in the design of the Phase II diamond drill program.

Quality Control and Quality Assurance

Samples (807) and control samples (59) from the 2024 Trenching program have been sent to Andes Analytical Assay Spa. (“AAA”) in Santiago Chile, for preparation and analysis. AAA meets all requirements of International Standards ISO 17025:2017 that includes ISO 9001 requirements for analytical procedures. Samples were analyzed using AAA’s Fire Assay Fusion method (AEF_AAS_1E42) with an EAA finish for gold and by a 43-element four acid digest ICP-MS-OP analysis (ICP_AES_HF43m), and ICP_AR01_MS_OP01 for mercury determination, with additional analysis for Ore Grade Au (AEF_GRV_1E4) and Ore Grade Cu (4A_HF_AAS_1E18SL).

Results are 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 (2.73%), inserting OREAS series standards (total 2.60%, including OREAS 153a, OREAS 523, OREAS 601c, OREAS 620, OREAS 502C) and duplicate samples in the field and laboratory (1.98%), obtaining a total of 7.31% CopperEx QAQC control.

Exploradora Norte Advanced Exploration Targets.

• The Franja del Oro Target contains sediment and volcanics hosted gold mineralization with associated replacement textures and alteration consistent with epithermal gold deposits that form distal to a porphyry copper-gold system. The Franja del Oro target hosts multiple parallel, north trending stratigraphically and structurally controlled mineralized zones. 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, continuity (along strike) and to define individual drill targets. CopperEx has identified gold mineralization over approximately 7 kilometers along the ADLP system (surface rock geochemical results). CopperEx leveraged the strong 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. 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.
