METALLIS SECURES DRILLING CONTRACT FOR MAIDEN PROGRAM AT GREYHOUND PROPERTY, IDAHO

VANCOUVER, BC, July 15, 2025 /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 – May 21, 2025) 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 planned drill program to test a robust structural corridor with confirmed high-grade mineralization at surface and underground;
• Program targets 3.5 km-long mineralized shear zone with multiple historic mining adits; and
• First-ever drilling campaign on the Property.

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.
