/CNW/ -

Metallis Resources Inc.

(TSXV: MTS) (OTCQB:

MTLFF) (the "Company" or "Metallis") is pleased to announce it has signed a drilling contract with

Foraco Drilling Ltd., a leading global drilling services provider, to carry out the upcoming inaugural

drill program (the "Program") at the Company's optioned Greyhound Property, located in the historic

Stibnite Mining District of central

Idaho, USA

. The Company has filed the required Notice of Mining

Exploration Activity with respect to the patented claims, allowing the Program to begin in August.

The Program is designed to test high-grade silver-gold-antimony targets (Metallis Resources news

release –

) within a 3.5 km-long mineralized shear zone. The area hosts several

historic mining adits but has never been drill tested using modern exploration methods.

Metallis CEO,

Fiore Aliperti

, commented: "Today marks a significant milestone for Metallis.

Meticulous planning and preparation took a number of months, and now we're ready to drill test this

very exciting precious metals and critical minerals target. The Greyhound Property sits in the heart

of

Idaho's

historic Stibnite Mining District, both the historical results and our surface exploration to

date has already delivered exceptional results, the geo-political support has never been stronger,

and it's the Property's maiden drilling campaign." He went on to add "With Foraco's proven expertise

and our permits now secured, we're positioned to unlock significant value for our shareholders. This

inaugural drill program represents a key milestone within our strategic vision of advancing high-

quality assets in mining-friendly jurisdictions with strong commodity fundamentals. The timing couldn't

be better, with silver and gold at record highs along with growing recognition of antimony as a critical

mineral essential for certain defense technologies, metals manufacturing and in the semiconductor

industry."

Key Highlights:

Drill contract signed with Foraco Drilling, a globally recognized drilling contractor;

Approximately

2,000 m

About the Greyhound Property

I n

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.
