NEWS RELEASE

PORTOFINO DISCOVERS NEW SULPHIDE MINERALIZATION ZONE, SOUTH OF

OTTER PROJECT, RED LAKE, ONTARIO

Vancouver, B.C., June 23, 2020. PORTOFINO RESOURCES INC. (POR: TSX-V) (POTA: FSE) (“Portofino” or

the “Company”) is pleased to announce the successful completion of its recent field program on the South

of Otter project near Red Lake, O ntario. The Company conducted prospecting and geological mapping

along strong conductors identified in both the Company’s winter electromagnetic (“EM”) ground survey,

and by Gold Corp’s interpretation of 2001 airborne magnetic data. A total of 32 samples were collected

to test various styles of mineralization, lithologies, and alteration.

The geological crew discovered significant semi-massive to massive sulphide mineralization along a newly

identified, 1.6-kilometer-long fault zone , which exists along the contact of felsic volcanic and mafic

intrusive rock units. This newly defined zone is located ~500 meters south of previously identified gold

soil sample anomalies and EM conductors. A total of 12 samples were collected along this (deformation)

zone to test the presence of Au, Ag, Cu, and Zn mineralization . Typical precious mineral host rocks

containing massive sphalerite, chalcopyrite, and arsenopyrite were identified along this fault zone.

Further prospecting and geological mapping on the margins of th is fault zone identified quartz -sericite

alteration in the volcanic wallrock . This alteration is highly significant, as many gold deposits in Ontario

are either directly hosted in this mineralization or exist in close relationship to this type of alteration and

a fault zone. Other projects containing this type of mineralization along similar deformation zones include

the Great Bear Resources (“GBR”) Dixie project and the Uchi Lake gold mine.

The 5,120 hectare (South of Otter) property is contained within the Birch -Uchi-Confederation Lakes

greenstone belt which hosts the world-renowned Red Lake gold deposits and includes the Dixie project

currently being drilled by Great Bear Resources Ltd. GBR continues to report exciting drill results with

mineralized intersections commonly returning bonanza gold grades in association with coarse visible gold

grains. Portofino’s property is located approximately 9 km east of GBR’s claims.

The Portofino property contains excellent targets for both Red Lake-style gold mineralization as well as

gold bearing base metal prospects. Historical work on the claims included prospecting, sampling, limited

drilling, and airborne magnetic geophysical surveys.
