Mobile MT Geophysical Survey Outlines Expanded Potential at

Red Canyon’s Kendal Copper Project

Vancouver, British Columbia, August 20, 2025: Red Canyon Resources Ltd. (“Red Canyon”

or the “Company”) (CSE: REDC | OTCQB: REDRF), is pleased to announce that final processing

has been completed and inversion models have been received from Expert Geophysics Surveys

Inc. related to a 258 line-kilometre mobile magnetotelluric ( “Mobile MT ”) heliborne survey

completed in July 2025. This survey covered the entirety of Red Canyon's Kendal property located

in west-central British Columbia. The Company is focused on impactful, value-added exploration

to discover copper and copper-gold deposits in established mineral belts in North America.

Company Highlights:

• Mobile MT is a leading geophysical technology, which aids in the identification of geologic

features, structures, alteration halos and contrasting lithologies in the subsurface. In

addition, potential mineralization from near -surface to deeper than one kilometre from

surface can often be inferred based on specific electromagnetic (EM) geophysical

signatures.

• Final processing and inversion modelling on the recently completed Mobile MT survey at

Kendal identified a 4 km by 3 km, SW to NE trending series of elevated conductive rocks.

Modelling by the Company shows multiple areas of elevated conductivity correspond with

known areas of alteration and mineralization at Kendal.

• Comparative studies of EM geophysical results over calc -alkaline porphyry copper

deposits in BC and others worldwide often show associated conductive and resistive

zones like those identified at Kendal.

• Vectoring studies to identify the core areas of the Kendal porphyry system have been a

priority for Red Canyon. Expanded field studies including detailed vein density/alteration

mapping, lithogeochemistry, in addition to the Mobile MT geophysics, are being finalized

prior to planned drilling this fall.

Wendell Zerb, the Chairman and CEO of the Company, commented: "New Mobile MT results at

Kendal suggest that the copper porphyry system is of larger scale than we previously mapped or

modeled. Areas with elevated conductivity correspond well with know n areas of

pyrite/chalcopyrite mineral ization and additional areas of elevated conductivity with adjacent

resistivity highs are of particular interest. The expanded size potential outlined by the Mobile MT

geophysics makes Kendal comparable in scope to some of the larger scale porphyry copper

systems globally and we believe Kendal could host multiple porphyry centres. Our fall drilling will

focus on the most advanced target at Kendal Ridge, which we believe corresponds with one of

these high potential porphyry centres."

Kendal Project

Kendal c omprises eight 100%-owned mineral claims tota lling 3,582 hectares located in west -

central British Columbia approximately 25 km northeast of the city of Terrace, a regional

infrastructure hub with a well -serviced airport. Infrastructure is excellent with four intersecting

highways, hydroelectric power, rail corridors and port facilities approximately 120 km to the west

at Prince Rupert. The main project area has direct logging road access, 8 km east from Highway

16. The project area lies within the traditional territory of the Kitselas First Nation.

survey.

In the fourth quarter of 2024, a first ever five-hole drill program at the Company’s Kendal project

confirmed the discovery of a new porphyry copper system. All drill holes intersected significant

porphyry-style alteration, multi -generational vein sets and highly anomalous copper and

molybdenum mineralization (see news release dated January 13th, 2025). To prepare for 2025

drilling, t he Company has completed vectoring studies including alteration and vein density

mapping, new lithogeochemical sampling and project wide Mobile MT geophysics.

Mobile MT - Expert Geophysics Surveys Inc.

Expert Geophysics Surveys Inc (“Expert”) completed 258 line-kilometres of Mobile MT on NNW

to SSE lines , at 200 metre spacing, spanning the entire Kendal project area (Figure 1) in July

2025.

The final data processing, colour imaging and mapping have been completed. Red Canyon has

reviewed the data and interpreted results with Expert and with independent 3rd party geophysicists

and geoscientists familiar with this type of survey.

Final survey results defined through processing and inversion modelling , identified a 4 km by 3

km, SW to NE trending series of conductors and resistors at Kendal. Importantly, modelling

suggests multiple conductive zones correspond with know n areas of alteration/mineralizatio n.

New areas with similar conductive signatures suggest the Kendal mineral footprint has

significantly expanded.

The 2024 diamond drill ing program at Kendal encountered an extensive mineralized alteration

footprint indicating a porphyry system with a massive amount of associated fluid flow. This large

alteration footprint and corresponding multiple generations of hydrothermal veins provides

confidence regarding the scale of the hydrothermal system.

New results from the Mobile MT further establishes confidence regarding the scale of the

hydrothermal system at Kendal and its potential to host multiple higher-grade mineralized centres.

Furthermore, work-to-date, provides strong evidence that areas of the Kendal system are eroded

to the level of the primary potassic alteration zone of the porphyry system. This suggests vectoring

to higher grade centres is likely lateral versus significantly at depth from areas previously drill

tested. Mobile MT sections including Line 1220 (Figure 4) show areas of elevated conductivity

and resistivity at, or relatively close to surface.

target areas.

In Q2 of 2025, Red Canyon completed an expanded rock sampling program, collecting 231

samples. Work within the Kendal Ridge area (Figures 2, 3, 4, 5) outlined the strongest reported

porphyry-style veining and mineralogy at Kendal to-date. The Kendal Ridge area is the focus for

the planned 2025 drill program.

Mobile MT has outlined new areas of interest to the NE within the project area (Figures 2, 3 and

6). Section 1400 shows a continuous trend of elevated conductivity similar in scope to other known

areas of interest. In addition, airborne magnetics show a series of complex magn etic highs and

lows coincident with new EM signatures. Outcrop exposure and thus geochemical sampling in

this area is limited although historic stream sediment samples in drainages cutting the area have

elevated geochemistry with values up to 465 ppm copper. Red Canyon plans to conduct additional

geochemical sampling in the area later this year.

Comparable MT signatures for other copper porphyry mineral systems

Copper porphyry systems typically convey a wide range of EM related signatures depending upon

the many variables that define any particular mineral system. For instance, porphyry systems with

intact lithocaps versus systems with exposed mineral cores can manifest either elevated

conductive or resistive EM anomalies. A summary stud y outlined in Figure 7 concluded BC

porphyry copper deposits have a variety of signatures: most calc-alkaline systems (like Kendal)

are associated with conductors given that these mineral systems typically have large associated

pyritic or phyllic alteration zones. Within these systems the po tassic core often manifests as a

resistive target.
