Metallis Kicks Off 2025 Exploration Season at Greyhound Property, Idaho

METALLIS KICKS OFF 2025 EXPLORATION

SEASON AT GREYHOUND PROPERTY, IDAHO

VANCOUVER, BC

,

July 8, 2025

/CNW/ -

Metallis Resources Inc.

(TSX-V: MTS) (OTCQB:

MTLFF) (the "Company" or "Metallis") is pleased to announce the commencement of the company's

2025 exploration program with the first ever geophysical survey at its Greyhound Property (the

"Property") in central

Idaho

. The high-resolution drone magnetic survey (the "Survey") will identify

and refine targets in advance of the Company's planned summer 2025 drill program. A total of 298

line-kilometres will be flown over the entire property with the resulting data expected to further

delineate structural controls associated with known mineralization. The Property hosts multiple high-

grade silver-gold-antimony prospects within the historic Stibnite Mining District, a prolific region in

Idaho

known for antimony production. Mineralization at Greyhound is associated with a 3.5 km-long

shear zone featuring multiple historic adits and which remains untested by modern drilling or

geophysics.

Dave Dupre

, VP of Exploration for Metallis, commented "We're very excited to kick off the 2025

exploration season with the first ever geophysical survey at the historic Greyhound Property. Building

on 125 years of previous prospecting and historic mining, this marks a major milestone in advancing

the Property through the application of modern exploration techniques. With three priority drill targets

already outlined and several other zones under evaluation, the survey will help us better understand

the structural architecture that controls the mineralization. This work will both significantly expand our

knowledge across untested parts of the Property and aid in refining the existing drill targets." Dupre

added "With antimony prices remaining highly elevated and precious metals hovering near all-time

highs, the timing is ideal to aggressively advance this highly prospective asset."

About the Survey

The drone magnetic survey is being conducted by Pioneer Exploration Consultants Ltd., a global

leader in UAV-based geophysical services. The survey, totaling 298 line-km, will consist of high-

resolution magnetic data collected at

25 m

line spacing flown perpendicular to the known mineralized

shear zone (See map below). Results from recently completed rock geophysical testing

demonstrates that the mineralized material displays anomalous magnetic susceptibility values helping

distinguish different rock types and mineralized zones (See Metallis News Release dated

February

13, 2025

). Key objectives of the Survey include:

Identifying cross-cutting structures or faults

that may host new high-grade shoots and

support future drill targeting;

Tracing the Greyhound shear zone

beneath overburden to identify magnetically destructive

alteration patterns associated with mineralization;

Exploring previously untested terrain

for parallel shear zones, similar to those observed at

the Birdie and Akita showings.

The results will also be used to guide any future Induced Polarization surveys along with a drill

program planned for summer 2025.

About the Greyhound Property

In

February 2024

, the Company optioned the Property which is located in

Custer County, Idaho

,

approximately 42 km northwest of the town of

Stanley

and 35 km south of Perpetua Resources'

Stibnite Mine. The Property was the center of an active silver mining camp in the early 1900's and at

one point contained a smelter and two active mines situated along the 3.5 km Greyhound shear.

The Greyhound targets are hosted by prominent shear zones with polymetallic quartz - sulphide

veins containing elevated concentrations of Au, Ag, Sb, Pb and Zn. They are comparable to

numerous mines in

North Idaho's

Silver Valley

along Interstate 90. This famous district is one of the

most prolific silver districts in the world. The total quantities produced are impressive: over a billion

ounces of silver, 3 million tons of zinc, and 8 million tons of lead totaling over

$6 billion

in value,

ranking the

Silver Valley

among the top ten mining districts in world history.
