CORDOBA MINERALS ANNOUNCES REVISIONS TO THE EXPLORATION PROGRAM AT THE PERSEVERANCE COPPER PROJECT IN ARIZONA

Cordoba Minerals Corp. is revising its proposed 2026 exploration program at the Perseverance copper project in Arizona. The Perseverance project is a 51:49 joint venture with Bell Copper Corp.

The 2026 exploration program, originally announced on June 8, 2026, contemplated deepening three existing drill holes to test a chargeability anomaly interpreted as potential blind supergene chalcocite blanket beneath a leached cap. The three holes were originally stopped in hematite, goethite-rich, leached cap rocks beneath a young, 20-million-year-old basalt flow covering Proterozoic and Laramide basement rocks. In Arizona this is indicative for the potential for copper-rich chalcocite mineralization replacing pyrite and chalcopyrite below the leached cap rock.

Field checks subsequently found that the collars of the three earlier holes were not viable for re-entry. While another location on private land owned by the joint venture were considered, relocating the drill pad to this location was not considered viable.

As a result, in order to test the chargeability anomaly, drill testing will need to be conducted from Arizona State land. This will require a longer permitting lead time, meaning drill testing of the anomaly is now targeted for the second half of 2027. A revised exploration program and budget will be established once the proposed drill locations on Arizona State land have been confirmed.

Cordoba's Interim chief executive officer, Quentin Markin, commented: "We are disappointed that we will not be able to accelerate the testing of the anomaly using the existing drill holes. Nevertheless, the prospectivity for supergene copper enrichment below the leach cap remains. The team will now be working to determine the best drill locations on State land in order to conduct this drill test later in 2027."

The Perseverance copper project is located in Arizona's Copper Triangle, a Tier 1 jurisdiction with major copper deposits and mines. The project is located 50 miles north-northwest of Freeport McMoRan's Bagdad copper mine, approximately 19 miles southeast of Kingman, Ariz., and 150 miles northwest of Phoenix, with a land package comprising more than 19,000 acres.
