Coyote Copper Mines expands Copper Springs by 2,000 acres

Toronto, Ontario--(Newsfile Corp. - August 5, 2026) - Coyote Copper Mines Inc. (TSXV: CCMM) ("CCMM" or the "Corporation") is pleased to report the results of its Phase 1 and Phase 2 soil geochemistry program at the Copper Springs Project, located in Arizona's prolific Copper Triangle. The program has delivered exceptionally strong copper ("Cu") and molybdenum("Mo") anomalies, validating the large-scale 3D spectral IP inversion of CSEM-MT geophysical "donut" features announced on May 12, 2026.

In response to these results, CCMM has staked an additional 2,000 acres, increasing its total land position to 774 BLM mining claims. This encompasses approximately 16,000 acres (6,475 hectares or 65km 2 ) of prime copper lands in Arizona.

CEO Dan Weir commented: " Both the copper and the molybdenum values were consistently much higher than we expected, outlining large anomalous zones. The soil samples also show the incredible potential of the Central Zone, which includes Santa Ana, the Maher zone, as well as indicating a significant footprint at Gibson and the areas surrounding the deep 3D spectral IP inversion of CSEM-MT "Donut" shape anomaly. The soil samples appear to validate the geophysics data, and together they suggest two large, porphyry copper systems: Central Zone and the Northwestern Area just north of the Gibson Mine. "

Dan Weir also adds: "Unlike the adjacent Resolution Mine where mineralization begins at ~1,200 m depth, the Central Zone Targets are exposed at surface - evidenced by the mapping and channel sampling programs underway. This significantly reduces drilling costs, time to discovery and capital intensity of early exploration and is a rare advantage in a Tier-1 porphyry district. This alignment across geochemistry, geophysics, and geology significantly reduces exploration risk. The deep "donut" geophysics responses, large magnetic low, soil anomalies and preliminary geologic results in the Northwestern Area suggest the target is below the Pinal Schists, implying a preserved porphyry system at moderate depth closer to the property boundary with Resolution in the western half of the property. "

Important points to note in this press release:

The soil samples, both Copper and Molybdenum, values were higher than expected.

The soil samples validate the Geophysics previously press released on May 12, 2026.

We staked an additional 2,000 acres to the southeast due to the soil sample results.

Coyote Copper is starting additional soil sampling, drone mag, and geophysics programs, focusing on the Northeast, and Southeast parts of the project.

Program Summary

Soil Sampling - Figures 1, 2 and 3 :

1,606 soil samples collected (Phase 1 & 2): Program conducted January-April 2026

880 additional samples planned for Phase 3: 431 completed to date and delivered to Skyline Laboratories in Tucson, AZ

Remaining soils to be completed by the end of August

Sampling covers the Central Zone (Santa Ana-Maher), Gibson, and areas surrounding the large geophysical donut anomaly

Soil sampling is being done at 200m spacing: Infill sampling at 100m and 50m spacing is being carried out as appropriate

Soil sampling provides a practical tool for prioritizing follow-up field geologic mapping/sampling.

Copper soil anomalies form broad, coherent kilometre-scale clusters rather than isolated highs. These clusters coincide with mapped alteration zones and the geophysical donut feature, indicating:

In the Central Zone:

A multi-kilometre porphyry - style hydrothermal footprint

Circular area of strong copper fertility across three kilometres

Near-surface mineralization consistent with the upper levels of a porphyry system

In the Northwest area:

Evidence of propyllitic alteration in the Pinal Schists

Evidence of copper - moly veins and specularite veining in the Pinal Schists

2.5 Kilometre - long oval magnetic low

The presence of >1,000 ppm Cu in soils across several zones is highly significant in porphyry exploration, especially in areas with limited outcrop.

The Central Zone exhibits a 3 km-diameter copper anomaly (values exceeding 500 ppm Cu) that contains two discrete 1 km-diameter molybdenum anomalies (values exceeding 15 ppm Mo). New targets have been identified, and follow-up sampling programs are being planned.

Molybdenum anomalies are widespread and locally intense. Elevated Mo values (>10 ppm) are particularly important because Mo is:

A diagnostic indicator of porphyry copper systems

Typically associated with the deeper, more mineralized portions of porphyry intrusions

A strong predictor of system size and fertility

The combination of strong Cu and Mo anomalies across multiple zones materially strengthens the interpretation of a large, porphyry system - refer to Figures 1 (Cu in soils) and 2 (Mo in soils), and Figure 3 (additional soil sampling)

Copper concentrations across the 1,606 soil samples ranged from 2.6 ppm to 2,660 ppm (0.266%). A well-defined circular copper anomaly (3 by 3km) is centered on Santa Ana Zone, and which coincides with a shallow chargeability feature identified in historic geophysical data, and is related to a shallow donut outlined in the recent 3D spectral IP inversion of CSEM-MT.

Molybdenum values ranged from below detection limits to 59 ppm, averaging 3.24 ppm. Elevated concentrations occur in several other zones which correspond to surface mineralization.

The Central Zone Molybdenum-in-soils anomaly extends approximately 2 km × 1 km and corresponds to a Cu-Mo stockwork hosted in porphyry intrusives, Pinal Schist, and Madera Diorite. The vein assemblage is dominated by Type-J, Type-K, Type-L (quartz veins with chalcopyrite blebs), and BMQ (banded molybdenite-quartz) veins, is part of a well-developed Cu-Mo porphyry-related hydrothermal system.

In surface environments, copper is readily oxidized and mobilized, frequently producing supergene enrichment, whereas molybdenum remains relatively immobile under chemical weathering. Consequently, porphyry copper systems commonly display a molybdenum core enclosed by a copper halo in their geochemical footprint.

Claim Staking

The recent claim acquisition is strategically important, as it covers the projected extensions of several significant copper and molybdenum soil anomalies. It secures the southeastern continuation of the Santa Ana mineralized corridor, as well as the southeastern extensions of the Gibson target areas - refer to Figure 4 (Claim staking)

Geology and Surface Mapping Program

Mapping, Structural Analysis, and Channel Sampling are being carried out in the new Central Zone, where strong quartz-chalcopyrite millimeter to centimetric vein stockwork mineralization outcrops over 350m of exposure.

Data Compilation, Synthesis and Interpretation

The May 12, 2026, geophysical news release outlined a multi-kilometre donut-shaped magnetic low surrounded by 3D spectral IP inversion of CSEM-MT anomalies - a classic signature of magnetite-destructive phyllic alteration and sulphide-rich shells.

The soil geochemistry now directly confirms this geometry.

Independent datasets all outline the same porphyry-scale footprint:

Drone Magnetics - refer to Figure 5 : Large, coherent magnetic low at centre

3D Induced Polarization ("IP") Survey: Shallow chargeability high on two historic lines

Controlled Source Electromagnetics ("CSEM") and Magneto-telluric ("MT") surveys: Deep conductivity contrasts creating the Geophysical Donut geometry - refer to Figures 6, 7 and 8

Hyperspectral Imaging: Lower temperature Propylitic halo surrounding a Potassic core

Potassic alteration forms in the inner core of a porphyry system, where temperatures are highest and fluids are K-rich: It is the most economically important alteration type because it commonly hosts chalcopyrite ± bornite Cu mineralization as seen in Central Zone

Propylitic alteration forms the outer, cooler halo of the porphyry system: It is widespread and typically surrounds phyllic and potassic zones

Extremely important for vectoring towards Cu-Mo mineralization

Was identified in the Pinal Schists in the Northwestern Area

Geological Mapping confirms a multi-kilometric hydrothermal system: Multi-generation breccias, phyllic / propylitic alteration, multiple intrusive phases, pyrite-chalcopyrite mineralization

These features are consistent with the upper and lateral portions of a porphyry system, and their distribution corresponds to the geophysical footprint of the Northwestern Area, at depth, and the shallow Central Area

Why the Geophycial Donut Matters

The "Donut" anomaly - similar to features used by BHP in global porphyry targeting - indicates:

Large Alteration System = Large Tonnage Potential: The scale of the donut exceeds the 2-3 km diameter commonly referenced in BHP's work in Chile and Serbia

Multi-Phase Porphyry Architecture Magnetic lows, chargeability highs, conductivity contrasts, and hyperspectral halos all match the expected geometry of a large porphyry centre

Near-Surface Targets - unlike the adjacent Resolution Mine (mineralization begins at ~1,200 m depth): Central Zone targets begin at or near surface, reducing drilling cost and accelerating discovery

When multiple geophysical and geological datasets align on the same geometry, the probability of a significant mineralized system increases substantially.

Technical Parameters

Soil samples were collected by Mineoro contractors under the guidance of the QP and in accordance with Mineoro protocols. The B and C soil horizons were sampled and screened to pass 60 mesh. Screened samples of approximately 400 grams are placed in pre-labeled cloth bags and sealed immediately upon collection to maintain sample integrity and security. Samples are subsequently submitted under secure chain-of-custody procedures to the laboratory for analysis. Quality control measures included the systematic insertion of certified reference standards and field duplicates at a rate of approximately 5%.

Geochemical analyses were performed by independent commercial laboratories holding ISO/IEC 17025:2017 accreditation. Multi-element analysis via aqua regia digestion (ALS Code ME-MS41) was selected for partial-extraction targeting sulphide and volatile mineralization, while 4-acid digest multi-element analysis (American Assay Laboratories 52-element suite) was utilized for near-total matrix breakdown. Both laboratories maintain comprehensive internal Quality Assurance/Quality Control (QA/QC) programs incorporating certified reference materials (CRMs), analytical blanks, and duplicate split analyses within each analytical batch to ensure verifiable data precision and accuracy

Appendix

Zonge International completed the field work for the CSEM/SIP

Zonge International Acquired CSEM/SIP and broadband MT data on the Copper Springs Project on a 3D grid. Vector stations of Ex, Ey were planned and setup at 59 stations. Roughly half of the stations measured Hx, Hy magnetic fields. 14 transmitter dipoles are planned to be read from 7 transmitter locations.

The transmitted signal was a 100-percent duty-cycle square wave. Initial base frequencies were 0.125, 1, 8, and 64 Hz. Total read time was approximately 2 hours per transmitter dipole.

All MT data was acquired from 0.01-1,024Hz, the data was collected before and after the CSEM/SIP reads. All data was acquired at 4096 samples per second.

A distant remote reference site was deployed. The remote site was deployed away from powerlines, pipelines, and other cultural electromagnetic sources to the extent possible. A location to the SE of the grid was chosen.

ZONGE surveyed the station locations and wire path using Garmin 64s Handheld GPS.

All acquired field data was checked through a QA/QC review and processed daily using the Zonge CSEM and MT Processing workflow. The data was processed in two large batches. One about halfway through the project and once at the end.

Instrumentation consisted of ZONGE broadband ZEN receivers. Magnetic field data was acquired with ZONGE ANT-4 low frequency broadband induction feedback coils. There will be spare receivers on site if possible. The receiver electrodes will consist of rusted steel plates.

The source for the CSEM/SIP data was a Zonge GGT-10, 10 KVA transmitter system. Multiple systems were utilized to minimize delays between transmitter reads If 90% of the source-receiver combinations and 90% of the MT soundings were successfully acquired without equipment failure or operator error.

Zonge Engineering - Drone Magnetic Survey

Zonge covered an area of 33 km2, with lines-oriented east-west at 50-meter line spacing. The approximate total coverage is 650 line-km.

Magnetic data was acquired using a Drone-based magnetometer system. The magnetic system comprises a Geometrics MagArrow cesium vapor total-field scalar magnetometer. The platform is a battery-operated DJI Matrice 300 RTK quadcopter. The magnetometer will be attached to the drone using 3-meter suspension cables. GPS positions and total field intensity data are recorded continuously at a sample rate of 1000 Hz and reduced to 10 Hz during post-processing. Drone speed will be set between 8 and 9 m/s, depending on the terrain. The 10 Hz data sampling interval, acquired at a speed of 9 m/s, yields approximately 1 m data points along flight lines. Flight altitude will be 50m AGL. The line locations are subject to change based on flight logistics, terrain, ground access, and the UAV's line of visual sight.

Flight paths were planned using Universal Ground Control Station terrain following software and uploaded to the UAV prior to each flight. Elevation data for flight altitude control will be sampled from USGS LiDAR terrain data.

High winds or sudden gusts of wind can cause a pendulum motion in the tow cable, which could set the sensor out of proper orientation. The Geometrics MagArrow has two Micro-Fabricated Atomic Magnetometer (MFAM) sensors ensuring that when one sensor is in its dead zone the other is at its optimum orientation. This avoids reading dropouts during the survey. The MagArrow has a 5nT heading error, which will be compensated for by flying a calibration flight. Data was compensated using software developed by Geometrics.

A base magnetometer recorded continuously at a fixed ground location to allow for diurnal corrections.

Deep Blue Geophysics - Interpretation of Zonge's Data

Deep Blue Geophysics LLC (Deep Blue) completed specialized Data Quality Assurance/Quality Control (QAQC) and advanced 3D inversion services, for CCMM. This project focused on the integration of broadband Controlled-Source Electromagnetic (CSEM) and Magnetotelluric (MT) data collected by Zonge at the Copper Springs site.

Deep Blue performed a rigorous audit of all Zonge deliverables to ensure the highest data integrity before modeling. This included:

CSEM Analysis: Inspection of response data for each transmitter-receiver pair to ensure signal quality.

MT Analysis: Systematic review of MT response data for each receiver station to identify and mitigate environmental noise or artifacts.

Joint 3D Spectral IP Inversion Deep Blue employed proprietary DeepBlueEM3D platform to conduct a sophisticated 3D Spectral IP inversion, providing a 3D model of resistivity and chargeability. This workflow integrates the CSEM and MT data to provide a unified subsurface model.

Integrated Dataset: Zonge CSEM and MT data was collected at approximately 59 receiver stations using 7 transmitter dipoles

Modeling Parameters: Inversions utilized a frequency range of 0.125 Hz to 1000 Hz to resolve spectral IP (resistivity amplitude and phase).

Staged Modeling Workflow: 1. Stand-alone 3D inversion of MT data. 2. Stand-alone 3D inversion of CSEM data. 3. Joint 3D inversion of the combined MT-CSEM dataset.

Objective: Interpretation & Drill Targeting Following the inversion process, Deep Blue collaborated with Coyote Copper Mines to interpret the 3D volumes. This phase ensures that geophysical anomalies are cross-referenced with geological context to provide prioritized recommendations for future drill-hole locations.
