Metallis Completes Successful Inaugural Drill Campaign at Greyhound, Idaho

Exploration Programs

METALLIS COMPLETES SUCCESSFUL

INAUGURAL DRILL CAMPAIGN AT

GREYHOUND, IDAHO

VANCOUVER, BC

,

Nov. 6, 2025

/CNW/ - Metallis Resources Inc. (TSX-V: MTS; OTCQB: MTLFF)

("Metallis" or the "Company") announces the completion of its 2025 diamond drilling program (the

"Program") at the Greyhound Property ("Greyhound" or the "Property") in central

Idaho, USA

. The

Program consisted of eleven diamond drill holes (See Table 1) totaling 1,605 meters ("m"), targeting

three previously identified prospects: Bulldog, 1350 and Birdie (See Map 1). This was the first drill

campaign ever conducted on the Property. The Company reports drilling intersected zones of quartz-

sulphide veining with visible mineralization. All samples have been submitted for analysis, with results

now being received. Following analysis and interpretation, initial results are expected to be released

in the coming weeks.

Dave Dupre

(Metallis V.P. Exploration) commented, "Greyhound's first drill program has been a

major success, delivering a meaningful improvement in our understanding of the mineralized

structures across all three tested targets. The visual results are encouraging, particularly the

continuity of the shear zones and the presence of polymetallic sulphides. We look forward to

receiving all the assay data which will allow us to quantify these observations and refine our

exploration model. These results will be key in guiding our geological team as we plan future drill

campaigns at Greyhound."

Bulldog target

At the Bulldog target, four holes totaling

484 m

were drilled from two pads centered on a 12-meter-

wide silver-gold-antimony shear zone where surface samples previously returned up to 4.9% Sb and

3,360 g/t Ag in grab samples (Metallis News Release,

October 30, 2025

). Drilling encountered semi-

massive sulphides hosted in quartz-sulphide veins containing pyrite, arsenopyrite, and trace

sphalerite, galena, and stibnite. Drill cuttings were also sampled at this location and will be

interpreted in conjunction with the drill core assays.

1350' Target

Three drill holes totaling

660 m

have yielded compelling results, revealing significant

sulphide

mineralization

across substantial lengths in each hole. Specifically, our drill holes

strategically

targeted several zones near the Lower Rufus

adit

, where historical channel sampling

*

revealed

impressive results along a 36.9-meter length, returning 1.85 g/t Au and an astonishing 785 g/t Ag*

(

News Release,

October 30, 2025

). Encouragingly, our mineralized shear zone has now

been traced over

60 m

vertically and

70 m

horizontally. With three definitive intercepts, we are

gaining a clearer understanding of the morphology of this promising mineralized shear zone.

Birdie Target

Four drill holes were completed at the Birdie target totaling approximately

462 m

. Two scissored drill

holes were drilled underneath the Upper Birdie portal. Two more holes were drilled off another pad,

50 m

southeast of the Lower Birdie. Notably, two trench cuts spaced

70 m

apart, along with historic

adits, have highlighted a substantial shear zone featuring quartz sulfide veins measuring

1m

to

3 m

in

total width.

Analytical Techniques

Core samples taken for assay are halved with a diamond saw with one half being sent to ALS Labs

(a laboratory independent from the Company) and the other half being retained on site for future

reference. All the samples are analyzed using the ME-MS61 methodology (Four acid Super Trace

Analysis). In addition, all samples are fire assayed (ME-GRA21) with 30-gram sample and a

gravimetric finish. Known standards and blanks are inserted into the stream of samples on a regular

basis. Additionally, all cores are photographed with a high-resolution camera for future viewing.

Assay results are expected throughout November and

December 2025

and will be reported as they

are received, interpreted, and verified that QA/QC has been met.

Acknowledgements

Metallis would like to sincerely thank its exploration team and all contractors (See Image 1) involved

in the successful execution of the 2025 Greyhound drill program. With their professionalism,

expertise, and dedication, the Company was able to complete the first-ever drill campaign at

Greyhound safely, on time, and within budget. In particular, we acknowledge the contributions of

Foraco Drilling, Brian Brewer Exploration, and the many subcontractors and individuals who worked

tirelessly to support field operations throughout the season. Their collective efforts were essential in

delivering a smooth and efficient program.

About Greyhound Property

I n

February 2024

, the Company optioned the Property which is 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 gold, silver, antimony (a critical mineral), lead and zinc.

They are comparable to numerous mines in

North Idaho's

Silver Valley

. 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, ranking the

Silver Valley

among the top ten mining districts in world history (Bennett, E.H., 2006).
