NEWS RELEASE

PORTOFINO MOBILIZES GEOLOGICAL CREW TO THE ALLISON LAKE NORTH LITHIUM PROPERTY

Vancouver, B.C., June 23, 2021. PORTOFINO RESOURCES INC. (TSX-V: POR) (OTCQB: PFFOF) (FSE:

POTA) (“Portofino” or the “Company”) is pleased to announce it has mobilized a geological crew

to the Allison Lake North lithium and rare elements (“Property”). The Property comprises 1,618

hectares (ha) and is located 100 kilometers (“km”) east of the town of Red Lake in northwestern

Ontario. The Property is accessible by well -established logging roads and a hydro -electric power

line transects the claim group. The geological crew has commenced mapping and sampling on the

property.

David Tafel, CEO of Portofino Resources states; “Securing strategic national supplies of

critical metals such as lithium and rare elements is being prioritized by Canadian and U .S.

governments. The Allison Lake region has been identified by the Ontario Geological Survey as

an important new exploration target area for lithium and rare -element mineralization and

we are excited to have “boots on the ground” and our exploration program underway.”

The Allison Lake North Property

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 pegmatit e granite

batholith and the Jubilee Lake metasedimentary rocks of t he Uchi Subprovince in northwestern

Ontario (Figure 1).

The 2003 Ontario Geological Survey (“ Breaks”) report described the Allison Lake batholith as the

largest known peraluminous granitic body in northwestern Ontario. Breaks concluded that, “the

Allison Lake batholith represents an important new exploration target for rare -element

mineralization and is the larg est such granite thus far documented in Ontario. This area has high

potential for further discoveries of rare-element mineralization”.

Based upon samples analyzed and included in the Breaks report, the outer rim of the Allison Lake

batholith possesses anomalously high concentrations of rare elements including lithium (“Li”).

Northwestern Ontario is host to several well-known Li and rare earth elements deposits that have

delineated resources and preliminary economic assessment studies (Figure 2). Of note is the PAK

Li deposit along the ‘Electric Avenue’ which contains one of North America's highest -grade, large

tonnage hard-rock Li resources. The PAK deposit has a mineral reserve in the proven and probable

categories of 5.77 MT averaging 2.06% Li 2O. The Spark Deposit, located 2.5km northwest of the

PAK, was winner of the “2019 Discovery of the Year Award”. Frontier Lithium recently announced

drill results from the Spark Deposit with hole PL-048-21 reporting 340 metres of 1.68% Li2O (TSX-

V: FL news - June 1, 2021).

Also notable in northwestern Ontario is the Separation Rapids lithium deposit owned by Avalon

Advanced Materials which has an estimated resource of 9.4Mt grading 1.35% Li 2O; the Georgia

Lake pegmatite deposit owned by Rock Tech Lithium with an estimated resource of 13.3 Mt

grading 1.09% Li2O; two deposits owned by Infinite Ore containing historical resources of 2M

tons grading 1.09% Li2O and 750,000 tons grading 1.38 % Li2O and the Seymour Lake lithium

deposit owned by Ardiden Ltd. and having an estimated resource of 4.8 Mt grading 1.24% Li2O.
