Metallis Reports Strong Progress from Mid-Season Drilling at Greyhound, Idaho

METALLIS REPORTS STRONG PROGRESS

FROM MID-SEASON DRILLING AT

GREYHOUND, IDAHO

VANCOUVER, BC

,

Oct. 9, 2025

/CNW/ - Metallis Resources Inc. (TSXV: MTS) (OTCQB: MTLFF)

(the "Company" or "Metallis") is pleased to provide an update on its 2025 diamond drilling campaign

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

Idaho, USA

.

To date, seven drill holes have been completed, totaling 1,143 meters, with drilling now advancing to

the final target area at Birdie (See Map 1). The Property hosts numerous historical workings and

offers significant untapped exploration potential, with this year marking the first-ever drill testing of

these targets.

The Greyhound is characterized by extensive shear zones that contain polymetallic quartz-sulfide

veins hosting silver, gold, and antimony mineralization associated with sphalerite, galena, and

stibnite. This multi-metal profile enhances the strategic importance of Property, as antimony

contributes roughly 20% of the in-situ value alongside silver and gold. Following recent supply

disruptions and export restrictions from

China

, antimony's role as a critical mineral has further

underscored the potential value of the project. Importantly, the Greyhound can be advanced based

on strong silver-gold fundamentals while retaining significant strategic supply potential from

antimony.

Dave Dupre

, VP of Exploration commented, "This year's drill program has delivered consistently

encouraging results as the team works to complete as much as possible before the end of the

season. To date, 1,143 metres have been drilled across seven holes targeting the Bulldog and the

1350' zones. The drill has now mobilized to the Birdie target where an additional four holes are

planned. We are highly encouraged by what we have seen so far and are excited to be just starting

exploration on the exciting Greyhound Property."

1350' Target

Drilling at the 1350' has expanded a high-grade silver-gold-antimony zone identified from historic

mining. The drill holes targeted several zones near the Lower Rufus adit where historical channel

sampling

†

along a 36.9 m length of this adit returned 1.85 g/t Au and 785 g/t Ag (10.6 g/t AuEq*).

The 2025 drill plan involved intercepting the shear zone above and below the adit as well as the zone

70 m

along strike to the south.

Three drill holes totalling

659.8 m

from a single pad have intercepted strong sulphide mineralization

over substantial lengths in each hole. Shear zones have varied from

7m

to

25m

(with unknown true

width) and contained sulphides such as arsenopyrite, pyrite, galena, sphalerite and stibnite, all

correlative to silver mineralization (See Image 1). The mineralized shear zone has now been traced

over

100 m

vertically and 70 meters horizontally. With 3 definitive intercepts, the team is now better

able to constrain the morphology of the mineralized shear zone.

Bulldog target

At the Bulldog target, four holes totaling 483.6 metres were drilled from two pads centered on a 12

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

3,360 g/t Ag. Drilling has confirmed semi-massive sulphide zones hosted in quartz-sulphide veins

containing pyrite, arsenopyrite, and trace sphalerite, galena, and stibnite.

Structural analysis revealed east-dipping geometries not previously identified, while post-mineral

dykes in holes GH25-01 and GH25-04 (See Image 3) may have locally offset mineralization. Multiple

mineralized veins were encountered across several holes, suggesting the system is more laterally

extensive than initially interpreted.

Birdie Target

Four drill holes are planned at the Birdie target totaling approximately

500 m

(See Image 5). The drill

is currently collared at the Upper Birdie where two scissored drill holes are planned underneath the

upper portal. Two more holes are planned off another pad,

50 m

southeast at the lower Birdie (See

Map 1). The Birdie target is located on a parallel trend to the main Greyhound shear. The results of

drilling are expected to increase our understanding of parallel shear zones.

Significant gold and silver have been found at the Birdie target, where two trench cuts located

70 m

apart as well as historic adits both revealed a sizeable shear zone with quartz sulfide veins of 1-

3 m

total width. An 80 cm float rock from the Upper Birdie cut yielded 4,900 g/t Ag with other samples

nearby returning up to 67.0 g/t AuEq*. A 50 cm quartz sulphide vein sampled from Lower Birdie cut

returned 18.15 g/t Au. These findings emphasize the Birdie as a gold rich zone and highlight the

exceptional gold values that were historically overlooked.

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 gold, silver, antimony (a critical mineral), lead and zinc.

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.
