Toronto, Ontario--(Newsfile Corp. - April 16, 2026) - Coyote Copper Mines Inc. (TSXV: CCMM) (the "Corporation") is pleased to announce that it 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, Nevada for Analysis.

As outlined in CCMM's April 9, 2026 press release, the Corporation has now initiated a multi-disciplinary exploration program across the project area.

Current program components

• Hyperspectral and satellite surveys
• Drone magnetic surveys
• MT and 3D IP 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 4 km and a width exceeding 600 m.

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."

CCMM's project area covers more than 58 km². Current mapping indicates the new zone extends for over 4 km and is more than 600 m wide.
