Drill Results

METALLIS ANNOUNCES IMPRESSIVE

SILVER/GOLD ASSAY RESULTS FROM

PHASE TWO PROGRAM AT GREYHOUND

PROPERTY, IDAHO

VANCOUVER, BC

,

Dec. 5, 2024

/CNW/ -

Metallis Resources Inc.

(TSXV: MTS) (OTCQB:

MTLFF) (the "Company" or "Metallis") is pleased to announce impressive silver and gold results from

the Company's second field exploration program (the "Program") completed at the Company's

Greyhound Property (the "Property"). The Greyhound Property is a high-grade silver/gold/antimony

project within the historic Stibnite (antimony mineral) Mining Camp, located in central

Idaho, USA

.

The Program included 129 soil samples, 61 geological mapping points and 44 rock samples, that

have delivered multiple high-grade silver and gold assays further refining the mineralized zones.

These results will enable the Company to optimize the scheduled drilling planned for early 2025.

Antimony assays are still pending and will be released once available.

Fiore Aliperti

, Metallis' CEO and President, commented, "Results from our second field program at

the Greyhound are incredibly encouraging and a testament to the work our technical team have been

delivering. The soil sampling, geological mapping, and rock sampling are helping us to refine our drill

targets and lay the foundations for an impactful 2025 exploration campaign. The continued

development of the Greyhound Project is a key focus for Metallis, and we are optimistic about the

potential this underexplored asset holds." He went on to add, "Additionally, attending the 2024 Idaho

Mining Conference was a fantastic opportunity to deepen our connections and relationships within

Idaho's

ever-growing mining and exploration community, along with other stakeholders including

government representatives. The knowledge gained and relationships established will undoubtedly

play a pivotal role as we continue to advance the Property. We were thrilled to meet these key

stakeholders and look forward to leveraging these connections as we move this project forward."

Key updates:

A total of 44 rock samples were collected, with results up to 4590 g/t Ag and an impressive

silver grade that averaged 504 g/t Ag across all samples.

Remarkable gold assays up to 18.15 g/t validate the underappreciated gold benefit at this

historic silver mine.

The Company recently attended the 2024 Idaho Mining Conference and engaged with drilling

companies, social governance professionals, government officials and multiple technical experts

to aid the advancement of the Greyhound project; and

Soil sampling defined several large multi-element soil anomalies that envelope all of the

promising prospects. Together with geological mapping and rock sampling has prioritized the

Birdie, the Bulldog and the 1350' zone as the initial focus for drill targeting.

Rock sampling results

Rock sampling was completed at known showings to help validate the structures that contain

elevated silver, gold and antimony and further refine the mineralized zones. A total of 44 rock

samples returned significant silver assays and impressively gold grades (See Map 1 Below) that

point to high-grade gold potential which appears to have been overlooked historically. Sampling was

focused on The Birdie, The Bulldog and the Akita. Two grab samples and two concentrate samples

taken historically from underground at the high-grade 1350' zone were delivered by the property

owner and sampled during this program, although those assays are pending.

The Bulldog provides one of the most developed targets on the property with sampling from this

program returning very elevated assays from a specific high-grade vein. This 10 to 20 cm vein

outcrops at surface for

13m

and returned silver assays up to 3360 g/t with an average silver grade

of 1624 g/t. This vein occurs within a wide shear zone that returned strong grades from the previous

chip-sampling program. Gold grades from 0.14 to 1.09 g/t were also present along with base metals

grades averaging from 1% to 5%. See table below of the 4 rock samples from this vein.

Rock Samples From High-Grade Vein At Bulldog (CNW Group/Metallis Resources Inc.)

At the Birdie target where two trench cuts are located

70 m

along strike from each other, significant

gold and silver results were also returned. At the Upper Birdie, the highest silver grades from this

program returned a significant 4900 g/t Ag from an 80 cm angular boulder dug up from the historic

trenching. Gold grades were also substantial at the Upper Birdie (See Map 2 Below) with the 7

samples averaging 3.0 g/t Au. At the lower Birdie, a rock sample taken from a 50 cm quartz sulphide

vein returned 18.15 g/t Au and 6 out of 7 samples were above 1.8 g/t Au. These elevated gold

results from the Birdie highlight the substantial gold grades at this target.

Rock grab sampling around the newly discovered Akita showing also highlights a new zone

200 m

to

the north of the Akita. Two samples returned 5.0 and 7.3 g/t Au Eq* and are located in the northern

part of a newly established soil anomaly. At the Ridge Cut, two more grab samples from the spoils

pile returned 1280 and 1740 g/t Ag respectively. Further work at the 1350' surface trench returned 2

grab samples of 5.5 and 8.6 g/t Au Eq*.

Soil sampling results

Soil sampling during this program was focused on extending coverage and further defining known

targets including the Birdie, Bulldog, and Akita. A total of 129 soils were collected across 8 selected

lines (See Map 3 below) taken perpendicular to the strike of the Greyhound Shear. Results

demonstrated strong anomalies in silver, zinc, lead and gold. A new extension to the Akita soil

anomaly,

300 m

east of the mapped Greyhound shear, further validates the strength of the

mineralization around Akita (a new discovery this year) and demonstrates the potential of other

parallel, underexplored shears. Zinc soil anomalies provide the best pathfinder element for identifying

silver mineralization and highlight a

600 m

long by

200 m

wide anomaly around the Birdie and the

1350' zone. At the Akita, a

300 m

long by

200 m

wide zinc anomaly has been outlined and, at the

Bulldog, the highest silver grade soil samples were returned.

policymakers, government officials and other regulatory professionals from across

Idaho

. Metallis

introduced the Company to a very receptive audience amongst the key players and stakeholders in

Idaho's

expanding mining and exploration community. Significant connections were made with local

drilling companies, social governance professionals, and various

Idaho

geological experts. These

connections will be critical in the development of Greyhound through the stages of exploration, with

the goal of establishing an economic mineral deposit.

Qualified Person

David Dupre

, P.Geo, Vice President - Exploration and the Qualified Person, as defined by National

Instrument 43-101, has reviewed, and approved the technical information contained in this release.

QAQC

All the rock samples were kept under the control of Metallis staff until they were delivered directly to

the ALS sample preparation facility in

Twin Falls, Idaho

. Analyses were then completed by ALS

Laboratories Ltd. in

Vancouver

, an independent certified laboratory. Blanks and standards have

been added to the samples stream by ALS along with internal QAQC protocol. All the samples were

initially analyzed by the Ultra Trace technique. Results that returned values greater than a pre-

determined threshold were then analyzed by element – specific methods as noted below.

ME-MS 41: Ultra Trace Aqua Regia ICP-MS.

ME-GRA21: Au, Ag 30g Fire Assay – Gravity Finish

Pb-OC46: Ore Grade Pb – Aqua Regia

Zn-OC46: Ore Grade Zn – Aqua Regia

Sb-ICP08: Sb – KCl/HCl digestion ICP-MS

As-OC46: Ore Grade As – Aqua Regia

Soil samples were collected predominantly of B horizon at predetermined locations across the

property. Once at the lab, samples were dried and crushed to 80 mesh (prep 41) before analysis by

the Ultra Trace technique. Gold Analysis was completed by aqua regia digestion with a 25g aliquot

(AuME–TL43).

Reference Information:

A grab sample is taken from a rock outcrop that is being assessed for the presence of valuable

elements. While taking the grab sample, the best-looking rock is chosen. Grab samples are by

definition selective. Grab samples are solely designed to show the presence or absence of

mineralization and are not intended to provide nor should be construed as a representative

indication of grade or mineralization at the Project.

Chip sampling involves taking contiguous rock chip samples along a line to define the width and

grade of a zone. Commonly, these are taken perpendicular to the strike of the mineralized zones

About the Greyhound Property

The Company acquired the Greyhound Property located in

Custer County, Idaho

, approximately 42

km northwest of the town of

Stanley

, in

February 2024

. The Company entered into an option to earn

a 100% interest in Greyhound with staged payments and exploration expenditures over a ten-year

period of US

$670,000

and US

$10,000,000

, respectively. Full terms are disclosed in the annual and

quarterly financial statements filed in 2024 and in a press release from the signing of the agreement

on

February 27, 2024

. This 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 a 3.6 km

mineralized shear zone. Since 1910, the property has seen limited exploration and only minor

development when the Greyhound Mine was reactivated and mined sporadically from 1980-1991.

The last remaining ore from this period was shipped to a smelter in 2000 and the property remains

substantially underexplored.
