NEWS RELEASE

PORTOFINO REPORTS GEOLOGICAL TEAM MOBILIZED TO

ALLISON LAKE NORTH LITHIUM PROJECT

Vancouver, B.C., October 03, 2022. PORTOFINO RESOURCES INC. (TSX -V: POR) (OTCQB: PFFOF) (FSE:

POTA) (“Portofino” or the “Company”) is pleased to announce that its geological team has mobilized to

the Allison Lake North property to follow-up on the Company’s 2021 channel and grab sampling

programs that reported encouraging values of up to 412 ppm lithium and 1040 ppm rubidium.

Recently completed high-resolution magnetic heli -borne survey results (NR-Sept 15, 2022) combined

with Portofino’s previous sampling and mapping efforts will be instrumental in guiding this phase of

ground prospecting , sampling and identification of mineralization typically associated with lithium -

bearing pegmatites. Exploration efforts will focus on the outer edges of the Allison Lake Batholith where

it comes in contact with the Jubilee Lake metasediments. Metasediments make excellent hosts for rare-

element pegmatites containing Lithium, Cesium and Tantalum minerals (“LCT”).

The Company’s geological crew led by Emerald Geological Services (EGS) is encouraged by what has

been encountered in the field thus far this month. Grey pegmatites in contact with metasediments have

been discovered containing key indicator minerals of garnet and tourmaline typical of LCT -pegmatites

(Figure 1).

Portofino’s previous sampling programs in 2021 returned anomalous rare-element results within the LCT

Goldilocks Zone, a fractionation corridor outlined by Green Technology Metals (Figure 2) believed to be

a zone ideal for the location of Li -mineralization such as the SJ Pegmatite . The SJ Pegmatite discovered

in 1964 by Stan Johnson lies only 1.5 k ilometres east of Portofino ’s southern claim group. This

occurrence represents the largest known pegmatite outcrop in the Jubilee Lake metasediments and

within the LCT Goldilocks Zone covering an exposed area of 30 x 35 m etres. Sampling of th e SJ

Pegmatite by the Ontario Geological Survey (“OGS”) in 2003 returned highly anomalous Li (140 ppm), Cs

(47 ppm), Ta (173 ppm), Nb (462 ppm) and Rb (1227 ppm).

Portofino’s CEO, David Tafel comments; “The high-resolution magnetic survey completed this summer

outlined priority prospecting and sampling areas to focus on this fall. Over the past week our team has

uncovered and sampled additional pegmatite outcrops and we are looking forward to seeing the lab

assay results from this sampling. New claims that we added following last year’s field season are also

being explored by Portofino for the first time and we are excited about the newly discovered prospects of

this ground.”

About The Allison Lake North Property

The Allison Lake North Property comprises 7 claims totaling 2,286 hectares and is located 100 kilometres

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 pegmatite granite batholith 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 Lithium property in Catamarca. The

properties are situated in the heart of the world -renown Argentine Lithium Triangle and in close

proximity to multiple world-class lithium projects. The Company also has the right to earn 100% interest

in three nort hwestern 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 discovered by Great Bear Resources and now owned

by Kinross Gold Corp. In addition, Portofino holds three other northwestern Ontario gold projects; the

Gold Creek property located immediately south of the historic Shebandowan mine, as well as the

Sapawe W est and Melema West properties located in the rapidly developing Atikokan gold mining

camp.
