NEWS RELEASE

PORTOFINO REPORTS AIRBORNE SURVEY RESULTS-

ALLISON LAKE NORTH LITHIUM PROJECT

Vancouver, B.C., September 15, 202 2. PORTOFINO RESOURCES INC. (TSX -V: POR) (OTCQB:

PFFOF) (FSE: POTA) (“Portofino” or the “Company”) is pleased to announce that it has received

results from a property wide high -resolution helicopter-borne magnetometer ("mag")

geophysical survey completed by Prospectair Geosurveys, on the Allison Lake North property

(the “Property”) . The survey comprised 406 line-kilometers of high-resolution mag with GPS

controlled 50 -meter line separations . The objective of the survey was to identify structural

weaknesses, geological contacts and possible fractionation directions in the Allison Batholith

that could potentially contain lithium bearing pegmatites.

The resultant total magnetic intensity field was very settled in absolute terms with increasing

intensity towards the eastern portion of the Prope rty (Figure 1). This may represent

fractionation west ward from a barren biotite -rich granite to a more peraluminous fertile

granitic melt. Low amplitudes in the southwestern portion of the Property may reflect

metasediments of the Birch -Uchi greenstone bel t. According to Breaks et al., 2003 1,

fractionation and crystallization or rare elements (Li- Cs-Ta) occur mainly at the outer edges of

the parental granite or those rocks in contact.

Portofino’s CEO, David Tafel comments; “Results of the airborne survey will be instrumental in

guiding an upcoming 3rd phase channel and grab sampling program where our previous

sampling returned values that included up to 412 ppm Lithium and 1040 ppm Rubidium. The

Allison Lake area has attracted a significant number of exploration groups due to its excellent

prospects. We are fortunate to be positioned in the heart of this fully staked, multi-company,

battery mineral exploration region.”

Preliminary interpretation of the survey results will aid in the next phase of ground prospecting

and mapping to those areas of high merit whe n combined with Portofino’s previous sampling

and mapping efforts.

interpretation of Portofino’s Allison Lake North property.

The resultant magnetic features reflect a possible fractionation zonation that has been

mirrored by the Company’s 2021 sampling and mapping program and efforts by Green

Technology Metals within the Allison Lake Batholith (Figure 2).

About The Allison Lake North Property

The Allison Lake North Property comprises 7 claims (113 cells) totaling 2,286 hectares (ha) and

is located 1 00 kilometers (“km”) east of the town of Red Lake in northwestern Ontario.

Numerous lithium deposits have been delineated in northwestern Ontario and host significant

reserves of lithium oxide- Li2O. The Property is accessible by well- established logging roads and

a hydro -electric power line transects the claim group. The Property contains significant

attributes that are key to the formation of lithium -bearing pegmatite dykes. It is positioned

along the contact between the Allison Lake pegm atite granite bat holith and the Jubilee Lake

metasedimentary rocks of the Uchi Subprovince in northwestern Ontario. This important

contact is now fully staked and subject to active exploration by multiple companies.

About Portofino Resources Inc.

Portofino is a Vancouver- based Canadian company focused on exploring and developing

mineral resource projects in the Americas. Portofino has an opportunity to earn a majority

interest in multiple lithium projects in Salta, Argentina and up to 100% of the Yergo Lit hium

property in Catamarca. The properties are situated in the heart of the world- renown Argentine

Lithium Triangle and in close pro ximity to multiple world -class lithium projects. The Company

also has the right to earn 100% interest in three northwestern Ontario, Canada lithium projects:

Allison Lake North, Greenheart Lake and McNamara Lake.

Portofino’s South of Otter and Bruce Lake projects are in the historic gold mining district of Red

Lake, Ontario, Canada proximal to the Dixie gold project discovere d by Great Bear Resources

and now owned by Kinross Gold Corp. In addition, Portofino holds three other northwestern

Ontario gold pr ojects; the Gold Creek property located immediately south of the historic

Shebandowan mine, as well as the Sapawe West and M elema West properties located in the

rapidly developing Atikokan gold mining camp.
