Metallis Resources Enters Option to Acquire Past-Producing Greyhound Silver/GOLD MINE IN Idaho, USA

Mergers & Acquisitions Property Options & Staking

METALLIS RESOURCES ENTERS OPTION TO

ACQUIRE PAST-PRODUCING GREYHOUND

SILVER/GOLD MINE IN IDAHO, USA

VANCOUVER, BC

,

Feb. 27, 2024

/CNW/ -

Metallis Resources Inc.

(TSXV: MTS) (OTCQB:

MTLFF) (the "Company" or "Metallis") is pleased to announce that it has entered into an option

agreement (the "Agreement") with Greyhound Mining & Milling, Inc., (the "Optionor"), to acquire a

100% interest in the Greyhound Property (the "Property"), located in the mining friendly state of

Idaho, USA

. The Property encompasses the past producing, Greyhound and Bulldog high-grade

silver/gold mines along with multiple historic workings. The Agreement is subject to customary

regulatory approvals.

Fiore Aliperti

, President, and CEO of Metallis stated

,

"Although we are seeing an overall change for

the better in investor sentiment, it's important to recognize the current market conditions and

understand the cost and dilution implications of large-scale exploration in the Golden Triangle at this

time. As the market continues to find its feet, it's critical for Metallis to add value in alternative ways,

despite the fact that our principal project remains the Kirkham Property. With that in mind, we

started the process in 2023 to look at possible acquisitions and the group that owned the Greyhound

stood out. It is important that if we are to add a second project to the MTS portfolio, not only does

the project need to show economic potential, the optionor needs to hold the same values as us.

These include putting the project, the Company, and the investors first."

He went on to add, "This option agreement demonstrates the confidence both parties have in this

high-quality resource asset as it favours long term success with low upfront costs. Metallis can

efficiently put funds into the ground, with resources and services more accessible than operating in a

remote access location. The Agreement for staged compensation over a 10-year period is

structured to reward both parties as the project advances through the stages of exploration and

development."

About the Property:

The 124 hectare Greyhound Property encompasses two past producing silver/gold mines

(Greyhound and Bulldog) in central

Idaho

. The claims outlined in the Agreement comprise 12

patented mining claims and 3 patented mill site claims with 1 patented pending mining claim and 8

patented pending mill site claims. The Property is road accessible via paved and gravel road and is

located 41 km from

Stanley

and 225 km from

Boise

, the state capital.

The Property is hosted in granites and granodiorites of the

Idaho

batholith and contains a 3.6 km

long mineralized shear zone highlighted by two past producing mines as well as multiple historic

surface workings. This shear zone, measuring up to

12 m

across, contains multiple quartz-sulphide

veins. Other parallel mineralized shears have been identified on the Property, but sill require

evaluation.

Ongoing compilation of historic assays by the Metallis geological team has suggested a robust

system that demonstrates consistent mineralization at multiple historic workings including the two

most developed underground operations at the Greyhound and the Bulldog mine.

In 1979 a 2,663kg bulk sample was taken from the lower Rufus Adit at the Greyhound Mine.

This sample returned a grade* of

: 2.39g/t Au, 1953 g/t Ag, 3% Pb and 2% Zn

and exemplifies

the high-grade nature of this target.

In 1991, channel sampling across the mineralized vein in the Rufus Adit, taken at systematic

intervals, returned an arithmetic average grade* for "ore-shoot 1350" of:

1.85 g/t Au, 785 g/t

Ag over a length of

36.88m

.

In 1999 a grade summary was prepared by Robert Longe to assess grade potential along the

Greyhound shear. His work on the Rufus Adit demonstrated average grades* for well

documented "ore-shoots" to be

684 g/t Ag and 0.85 g/t Au including 3% Zn and 1%

Pb

.

The similarity of values and

conservative approach does lend confidence to these values. They are presented for

completeness.

Property History

Initial exploration in the late 1800's led to multiple claims being staked along the Greyhound shear as

prospectors and miners discovered the high-grade silver mineralization at surface on Greyhound

Ridge. Five adits were driven into the mountain from 1896 to 1910 as local miners commenced small

scale mining at the Greyhound and the Bulldog with multiple other pits and shafts being sunk across

the Republican, the Buckhorn and the

Idaho

prospects. These prospects, along with the Greyhound

and the Bulldog, provided high grade silver/gold/lead mineralization to a smelter built on site, until

mining ceased with the decline of metal prices in 1910.

Since then, the Property has been privately owned with patented mining claims dating back to 1921.

It has seen little activity except for a period of minor production on a trial basis in 1979 when the

Lower Rufus Adit (Greyhound Mine) was driven

309 m

along the mineralized shear zone. It was

further extended to

458 m

in 1991. Several minor underground and surface sampling programs have

been completed, although the Property has never been explored by any modern techniques. Good

quality concentrates are reported to have been produced from the Greyhound mine.

Next Steps

The Greyhound Property provides large upside potential due to a lack of modern exploration being

performed over the Property's entire history. In the last 45 years, the Property has been held by a

family-owned business as part of a larger asset portfolio. This has left a well-endowed property off

the market, during a period where geological methodologies and approaches have changed, and

exploration technologies have evolved. This allows Metallis to leverage its exploration experience to

unlock the mineralized potential through geological mapping, drone arial surveys, geophysical

surveys, and diamond drilling.

Continued compilation of historic reports will help the team determine the true grade and tonnage

potential outside of the historic workings. To date, approximately

600 m

of horizontal workings have

been documented across the

3,600 m

shear zone leaving significant underexplored strike length left

for further testing. The last ore shoot encountered in the Lower Rufus Adit returned some of the best

grades on the Property that are comparable to many of the operating mines in the state. A further

3,000 meters of untested ground remains across multiple high-grade silver/gold surface showings

and pits. The system also remains open to depth as mineralization has been demonstrated over 500

vertical meters from the Rufus Adit to mineralization on top of Greyhound Ridge.

This region has recently seen exploration success where historic silver camps have been able to

outline sources at depth and this will be factored into the team's exploration programs. During initial

exploration, the team will be assessing the Property for source intrusions or disseminated

mineralization. The Property's location, within the

Great Falls

tectonic zone and the

Central Idaho

batholith also lends itself to the potential for porphyry mineralization due to mapped Tertiary aged

intrusions on the Property.

Agreement Terms:

US$670,000

, which commence on the date of signing
