COYOTE COPPER MINES INC. BEGINS EXPLORATION WORK ON NEW SULPHIDE COPPER ZONE

Coyote Copper Mines Inc. has begun work on a newly discovered zone, with exposed copper sulphide mineralization and magmatic breccias within the Copper Triangle of Arizona. Channel samples are being cut with a diamond saw and dispatched to American Assayers Laboratories in Sparks, Nev., for analysis.

As outlined in Coyote Copper's April 9, 2026, press release, the corporation has initiated a multidisciplinary exploration program across the project area.

Current program components:

• Hyperspectral and satellite surveys;
• Drone magnetic surveys;
• Magnetotelluric and 3-D induced polarization geophysical surveys;
• Relogging of historical drill core;
• Soil sampling;
• Mapping, logging and chip sampling;
• Channel sampling;
• Drill permitting.

Recent field efforts have led to the identification of a new mineralized zone, which includes a breccia pipe referred to as the Maher breccia. The broader zone remains under active evaluation, with current project mapping indicating a strike length of more than four kilometres and a width exceeding 600 metres.

Dan Weir commented: "The 96 historical drill holes and the historical resource at the Copper Springs project were largely focused on oxide and transition zone copper mineralization. Finding sulphide copper and molybdenum mineralization at surface, rather than at depths of roughly 1,200 m like the Resolution deposit, is a game changer for us. This new zone has already attracted the attention of larger companies."
