Coyote Copper Mines Inc. Announces Completion of Its Initial Geophysical Interpretation Revealing a Potential Large-Scale Donut Anomaly Consistent with Major Porphyry Systems

Coyote Copper Mines Inc. (TSXV: CCMM) has completed initial interpretation of its integrated geophysical and hyperspectral survey over the Copper Springs and Gibson claims in Arizona. The results reveal a large-scale, “donut-shaped” anomaly—a classic porphyry signature—defined by a central magnetic low ringed by chargeability highs and resistivity lows. Critically, the anomaly’s scale exceeds the typical 2–3 km diameter associated with major global porphyry deposits. The surveys included drone magnetics (650 line‑km), controlled-source EM, magnetotellurics, and 3D IP, combined with hyperspectral satellite imaging that mapped a propylitic halo around a potassic core. CEO Dan Weir emphasized that the feature is much larger than the donut shapes normally sought by major mining companies. Mineralization appears to start at or near surface, unlike the adjacent Resolution deposit where ore begins 1,200 m deep.

This news meaningfully advances the exploration thesis for Coyote Copper. While the company had previously released high‑grade rock-chip results (up to 22.41% Cu) and identified surface sulphide mineralization over a 4 km strike, the geophysical interpretation provides the first coherent picture of a system that could be far larger than initially suspected. The donut‑shaped anomaly is a textbook indicator of a mineralized porphyry core and, if confirmed by drilling, could define a resource that competes with world‑class deposits in the district. The fact that the anomaly is described as larger than typical 2–3 km systems is likely to capture market attention and raise the company’s profile. However, the interpretation is still purely geophysical; no drill data corroborates the target. Therefore, while the news is genuinely new, unexpected in its scale, and likely to be market‑moving, it remains an early‑stage milestone rather than a definitive resource confirmation.

Coyote Copper Mines Inc. is a junior exploration company that completed a qualifying transaction (reverse takeover) and began trading on the TSX Venture Exchange on April 13, 2026. Its flagship asset is the Copper Springs / Gibson project in the Arizona Copper Triangle, covering 58 km² (over 14,000 acres) via 693 BLM mining claims. The project sits adjacent to major operations, including Rio Tinto/BHP’s Resolution Copper, and lies within a region that has produced >37 billion lb of copper with an estimated >94 billion lb of unmined resources. The property contains more than 100 historic drill holes and a non‑43‑101 compliant historic oxide resource. Modern exploration is targeting both supergene oxide/transition zones and primary sulphide porphyry mineralization that surfaces at much shallower depths than nearby deposits.
