Vancouver, British Columbia--(Newsfile Corp. - May 30, 2024) - CopperEx Resources Corp. (TSXV: CUEX) (the "Company" or "CopperEx") announces results from a 1,279-meter reverse circulation ("RC") drill program at the Company's flagship Exploradora Norte Project. The eight drill holes were completed in the Agua de la Piedra ("ADLP") and Sorpresa zones of the Franja del Oro Target, part of15-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.

Dave Prins, President & CEO of CopperEx stated, "The inaugural RC drilling program at Franja del Oro demonstrates the robust gold grades and continuity at ADLP and importantly demonstrates that the newly identified surface gold mineralization at Sorpresa extends to depth and along strike. These results represent a significant step forward for the project and for CopperEx and once again highlight the gold endowment and economic potential of the Exploradora Norte Project. We are extremely pleased to have completed and published the results of the inaugural drill campaign, a little over three months since listing on the TSXV."

John Robins, Technical Advisor to CopperEx stated, "Exploration drilling at Exploradora Norte cut long runs of robust, gold mineralization in the near surface environment at the Sorpresa and ADLP zones which confirms our confidence in the upside exploration potential of Franja del Oro Target. Data from this round of drilling will be used to enhance the lithological, structural and alteration modeling at Franja del Oro which will be leveraged to vector toward additional gold mineralization in the next drill campaign."

Zoom Webinar

CopperEx Corp. will host a webinar to discuss the Company's recent results from the inaugural drill program at the Exploradora Norte Project. The webinar will take place on Thursday, May 30th at 11:00am PST/2:00pm EST.

Zoom Registration Link:

Management will be available to answer questions following the presentation. A replay of the webinar will be posted on our website by May 31^st at .

Highlights:

• Cut gold mineralization with associated pathfinder elements (arsenic and antimony) and intense alteration in all eight holes at ADLP and Sorpresa, a testament to the endowment and quality of the Franja del Oro exploration target (see results below).

• The 2024 RC drill program has successfully confirmed the gold grades and continuity at ADLP and has expanded the newly identified surface gold mineralization at Sorpresa along strike and at depth. These results represent a significant step forward for the 15 by 3-kilometer Franja del Oro Target and enhances its potential to host a large, high quality bulk minable gold deposit.

• Drilling at ADLP demonstrates that gold mineralization at Franja del Oro has a spatial association with porphyritic intrusions which are locally gold mineralized. In addition, quartz vein mineral assemblages consistent with the distal porphyry copper gold setting (e.g., A-RC-03; see below) suggest there is potential at Franja del Oro for a bulk tonnage porphyry target at depth.

• Completed eight drill holes totaling 1,279 meters of reverse circulation ("RC") drilling out of the planned 1,250 drill program within a 3-week timeframe from commencement of drilling. (See the Company's press release dated April 04, 2024).

• 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.

Drill Program Summary and Economic Geology

The highly successful 2024 RC drill program at Franja del Oro was designed to test the gold grade and continuity of key near-surface gold mineralized segments of the parallel Sorpresa (1,200 meters-long) and ADLP (850 meters-long) zones, which are part of the greater Franja del Oro Target that measures 15 kilometers by 3 kilometers and is defined by discontinuously exposed gold mineralization, alteration, brittle faults favorable (reactive) host rocks and pathfinder element geochemistry (arsenic and antimony). New RC drilling at Franja del Oro cut gold mineralization in every hole, substantially increasing the Company's confidence in the potential of the Sorpresa and ADLP zones and the greater gold endowed target area. These exciting results warrant follow up drilling which will focus on expanding the footprint of known mineralization and modeling the geological architecture at Sorpresa and ADLP to vector toward additional gold mineralization.

The distribution of gold mineralization (Figure 1A-E) intercepted by CopperEx in the Sorpresa and ADLP zones at the Franja del Oro Target is controlled by planar fabrics including geological contacts, damage zones (faults) and by the position of chemically reactive host rocks (carbonate-bearing sandstones). Alteration minerals associated with gold include silica, iron oxide, sericite, and clay together with the presence of open space quartz vein textures and locally breccias suggest that the gold mineralization is related to the epithermal clan of mineral deposits. Gold mineralization at Franja del Oro (ADLP) has a spatial association to porphyritic intrusions (holes A-RC-01, A-RC-04 and A-RC-05; Figure 1A) which are locally gold mineralized and contain quartz vein mineral assemblages including quartz + pyrite and quartz + magnetite which increase in intensity with depth (e.g., A-RC-03; Figure 1D). These observations are significant to the upside gold (and possibly copper) upside exploration potential at Franja del Oro because they suggest that the epithermal gold mineralization at Franja del Oro that is exposed at surface may be related to a gold (and copper) bearing porphyry at depth.

Overall Exploradora Norte and Franja del Oro Plan

Figure 2: Exploradora Norte - Property map including key target areas and surface and trench rock geochemistry⁵.

Sorpresa Zone (Franja del Oro Target)
A total of 3 RC holes (487 meters) have been drilled at the Sorpresa Zone to test the depth extent, 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. The results from the drill program are shown below.

Figure 3. Geological cross-section (B-B¹) showing the location of S-RC-02 (ADLP Zone) and historical drilling^1,2.

ADLP Zone (Franja del Oro Target)
A total of 5 holes (792 meters) were drilled at ADLP. 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.

Relevance of Oxide Deposit Gold Grades

To provide additional context regarding gold grades intercepted by CopperEx within the inaugural drill program, and how these may contribute to the projects economic potential, it's worth noting that the Kinross 2023 annual report indicates a heap leach grade of 0.22 gpt⁴ for the Fort Knox mine, the Kinross Round Mountain mine has a heap leach grade of 0.39 gpt⁴, and the Kinross Bald Mountain mine indicating a grade of 0.42 gpt⁴. Both the Fort Knox and Round mountain mines operate joint heap leach and mill operations, while the Bald Mountain mine is a standalone heap leach operation⁴.

Quality Control and Quality Assurance

Samples from the 2024 RC drilling 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 17025:2017that 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 (2.65%), inserting OREAS series standards (total 3.12%, including OREAS 153a, OREAS 523, OREAS 601c, OREAS 620) and duplicate samples in the field and laboratory (1.55%), obtaining a total of 7.32% CopperEx QAQC control.

The Company's priority is to advance exploration of the Franja del Oro Target at Exploradora Norte which 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 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.
