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.
