Coyote Copper Mines Inc. Is Advancing Not Only Its New Zone but Also Focusing on Historical Areas of Its 58 Square Kilometer Arizona Copper Project

Toronto, Ontario–(Newsfile Corp. – April 30, 2026) – Coyote Copper Mines Inc. (TSXV: CCMM) (the “Corporation”)

In CCMM’S press release dated April 16, 2026 it was announced that CCMM had begun work on its newly discovered sulphide copper zone. The Company also wants to emphasize the historical work and zones, which will be a big part of its exploration programs going forward, including drilling.

Using modern exploration techniques like Drone Magnetic Surveys, MT and 3D IP geophysics surveys as well as having geologists on the ground reassessing and mapping the older historical areas will help the company optimize its drilling program.

Dan Weir, CEO, commented, “We are very excited about the new zone we are exploring, but we don’t want to discount the current and potential value of the some of the other areas within the 58 km² of our Arizona project.”

40 Samples were collected and analyzed as part of the August 2025 site visit. The sampling was focused on the Gibson Structural Corridor (GSC) and the Santa Ana Stock (SAS). Sampling was completed by the Michael Feinstein and Mineoro staff. Samples are marked with spray paint, measured, described, and coordinates recorded from a Garmin handheld GPS. Sampling method utilizes a 2-man team with hammer and chisel, in which, a breaker and catcher work together to collect a volumetrically representative continuous chip sample across the marked interval. Samples are collected in 8 mil poly bags and sealed with zip-tie and numbered tag immediately after collection. Sample sites are labeled and photographed; a hand-sample is retained for reference inventory.

10 samples were taken across the Gibson Structural Corridor (GSC) in August 2025. Bedrock sampling was located in areas of observed copper oxide mineralization and across structural zones. Historic sorting piles in the West Gibson area were sampled to characterize the historic mineralization.

A total of 10 samples were collected. Copper values ranged from 0.091% to 22.41% with an average value of 6.688% Cu. Silver values ranged from below detection to 69.3 g/t with an average value of 15.6 g/t Ag.

The 4 samples from the West Gibson zone show very high copper grades ranging from 10 to 22%. These were select grab samples, collected from historic ore piles, to characterize the mineralization. Qtz+chalcopyrite veining, massive Chalcopyrite and associated hematite are observed in relation to a set of thin, mineralized porphyrytic dike sets which is parallel to the primary Gibson mine structure. The Silver content of 10.6 to 69.3 ppm is notable.

A total of 30 samples were cut across 41m of outcrop in Santa Ana Canyon and into the Santa Ana tunnel. Primary hypogene mineralization is observed in association with strong, potassic alteration, and this is expressed as a stock-work of type-A and type-B veins with a surface exposure of 120 x 40 m x 20m (L x W x D). Copper values ranged from 0.0881% to 1.379% with an average value of 0.3564% Cu. Molybdenum values ranged from 0.0006% to 0.1233% with an average value of 0.00851 Mo. Silver values ranged from below detection to 2.2 g/t with an average value of 0.75 g/t Ag.

Sampling completed during the August 2025 site visit was overseen by Michael Feinstein, QP, and carried out in an un-biased, representative nature. All samples were collected under Mineoro protocols and QA/QC procedures, securely stored, and maintained through submission to American Assayers Lab, an ISO-9001 certified facility. Samples undergo preparation (dry, crush, pulverize), four-acid digestion, and ICP-MS analysis for 51 elements. Samples returning more than 10,000 ppm copper were re-assay by ore grade methods.

Over-limit samples were re-analyzed by OG62 methods which involves a 4-acid digestion and analysis using ore-grade calibrations. All samples were collected under Mineoro protocols and QA/QC procedures, securely stored, and maintained through submission to American Assayers Lab, an ISO-9001 certified facility. Quality Control samples were inserted every 20 samples (5%). All certified reference standards were supplied by Analytical Solutions Ltd., of Toronto, Ontario. Certified reference standards returned values within 1% of certified values for Cu, Mo, and Ag; the results are deemed to be valid. American Assay Laboratories is independent of the issuer.

Since 1974, the Pinto Valley project has produced 4.7 billion pounds of copper and nearly 22.5 million pounds of molybdenum (Table 18). At its current rate of production, proven and probable ore reserves as of December 31, 2020 (407 million tons, averaging 0.31% copper and 0.007% molybdenum) will sustain operations until 2039 (Capstone Mining Corporation, 2021).

Dan Weir, CEO, commented, “CCMM’s projects have multiple zones with similar geology found throughout the Copper Triangle. We are targeting to have the same or larger resources and similar or larger grades than Pinto Valley and/or other mines in the area.”

Please note, the potential quantity and grade is conceptual in nature, that there has been insufficient exploration to define a mineral resource and that it is uncertain if further exploration will result in the target being delineated as a mineral resource.
