NEWS RELEASE

PORTOFINO RESOURCES EXPANDS LITHIUM FOCUS; ACQUIRES

ALLISON LAKE NORTH PROPERTY, EAST OF RED LAKE, ONTARIO

Vancouver, B.C., April 20, 2021. PORTOFINO RESOURCES INC. (TSX-V: POR) (OTCQB: PFFOF) (FSE: POTA)

(“Portofino” or the “Company”) is pleased to announce it has executed an agreement to acquire the

Allison Lake North Lithium and Rare Elements Property. The Property comprises 4 claims (80 cells) totaling

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 Allison Lake North Property adds to our Lithium property portfolio and is a highly strategic acquisition

for our Company ” states David Tafel, CEO of Portofino Resources. “Canadian and U.S. government

initiatives are increasingly focused on securing strategic national supplies of critical minerals, such as

lithium and rare elements, that are used in products such as EV batteries, mobile phones, solar panels,

wind turbines and broad military applications. Based on the geological and strategic geographic setting

of this property, we see a real potential to expand sources for these minerals in Northern Ontario.”

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 ). All

mineral claims that comprise this important contact are fully staked.

The Allison Lake batholith is a strongly evolved peraluminous granitic body that contains highly

anomalous rare -element mineralization along it’s outer rim. The SJ Pegmatite , located 6 km to the

southeast, is the largest pegmatite thus far discovered in the Jubilee Group metasediments occurring

alongside the western (granite) contact of the Allison Lake bat holith. The outcrop exposure measure s

35mx30m suggesting substantial width. This pegmatite is believed to be a n external dyke to the Allison

Lake batholith supporting evidence of outwards fractionation and rare earth volatile enrichment from the

fertile peraluminous granitic parent.

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

known peraluminous granitic body in northwestern Onta rio. Breaks concluded that , “The Allison Lake

batholith represents an important new exploration target for rare -element mineralization and is the

largest such granite thus far documented in Ontario. This area has high potential for further discoveries of

rare-element mineralization that occur in exocontact, metasedimentary-hosted pegmatites or as internal

pegmatites within the parent granite.”

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

batholith possess es anomalously high concentrations of rare elements including lithium(“Li”) of

190ppm, beryllium (“Be “), visible as beryl crystals, cesium (“Cs”) of 90ppm, niobium (‘Nb”) in the form

of visible ferro-columbite and rubidium (“Rb”) of 587ppm. The elemental distribution of these rare earth

elements within the batholith occurs within 1,500m of its western contact with the metasedimentary

rocks. Again, this provides evidence of fractionation and rare -earth element enrichment outwards from

the peralumi nous Allison Lake parent batholith. The Allison Lake North property is strategically

positioned along this 1,500m wide fractionation corridor.

Northwestern Ontario is host to several well -known lithium and rare -element earth deposits that have

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

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

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

of 5.77 MT averaging 2.06% Li2O. The Spark Deposit, located 2.5km northwest of the PAK, was winner of

the “2019 Discovery of the Year Award”. The Spark Deposit has a mineral resource estimate of 3.2 MT

averaging 1.59% Li 2O (indicated) and 12.2 MT averaging 1.36% Li 2O (inferred). Frontier Lithium recently

completed a Preliminary Economic Assessment that outlines life of project revenue of $8.5 billion over

26-year total project life, and a chemical plant producing 23,174 tonnes of battery -quality lithium

hydroxide monohydrate (LiOH-H2O) per year (FL: TSX.V news dated February 16th 2021).

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

Materials (avalonadvancedmaterials.com) which has an estimated resource of 9.4Mt grading 1.35% Li2O;

the Georgia Lake pegmatite deposit owned by Rock Tech Lithium (rocktechlithium.com) with an estimated

resource of 13.3 Mt grading 1.09% Li2O;, two deposits owned by Infinite Ore (infiniteore.com) 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. (ardiden.com.au ) and having an estimated resource of 4.8Mt

grading 1.24% Li2O.

Property Agreement Terms

The Company has the right to acquire a 100% interest in the Property by making payments to the

Optionors over the next three years totalling $78,000 in cash and issuing 800,000 Portofino common

shares. The Optionors will retain a 1.5% net smelter returns royalty on the Property.
