PORTOFINO IDENTIFIES ADDITIONAL GOLD MINERALIZATION AT SOUTH OF OTTER

PROJECT, RED LAKE PROPERTY

Vancouver, B.C., September 15, 2020. PORTOFINO RESOURCES INC. (POR: TSX -V) (POTA: FSE)

(“Portofino” or the “Company”) is pleased to report it has received assay results from the recent overburden

trenching campaign on the Company’s South of Otter property (the “Property”). The trenching was completed

on three prospective sites; the Cliff Zone, the Yellow Jacket Trench and the Silver Lining Trench. A total of 22

samples were submitted for fire assay to Activation Laboratories and 5 selective chip and channel samples

returned anomalous values for gold (base metal analyses are still pending).

Trenching was conducted at the Cliff Zone, the site of the Company’s initial gold discovery of high-grade gold

mineralization of 16 grams per tonne gold (“g/t Au”) (Portofino news - August 26th 2020) in a quartz vein

located 200 meters (“m”) southeast of Goldcorp’s 2002 drill hole (SF02-08). Bedrock exposed by trenching of

the Cliff Zone contained 2 (+25cm wide) quartz veins and a broader carbonate plus pyrite alteration zone

along the diorite and porphyry contact. Gold-bearing channel samples ranged from 137 ppb Au to 1,090

ppb Au. ( 0.137 to 1.09 g/t Au ). The 1 .09 g/t Au grade was returned from a 0.58m channel sample of

mineralized vein.

The Yellow Jacket trench was intended to expose mineralized bedrock associated with the 2001 Goldcorp

gold soil anomaly, located 650m to the south along a geophysically -interpreted structural break. Chip

samples across a width of 0.35m of a rusty intermediate volcanic unit returned a highly anomalous grade

of 372 ppb Au (0.373 g/t Au). A second , highly anomalous chip sample of a quartz feldspar porphyry

showed 220 ppb Au (0.220 g/t Au) over a sample width of 0.50m. A full list of the sample and assay results

is shown in Table 1.

Portofino’s CEO, David Tafel comments; “The gold values found in the Cliff Zone and new gold

mineralized showing in the Yellow Jacket trench continue to indicate the existence of wide-spread gold

mineralization within the South of Otter property. Our project has a limited amount of surface exposure

but with results to date and pending int erpretation of our recent airborne magnetic survey, we are

confident our technical team can continue to develop additional gold targets to be pursued by drilling

in the very near term.”

About the South of Otter Property

The 5,363 hectares Property is contained within the Birch -Uchi-Confederation Lakes greenstone belt

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

currently being drilled by Great Bear Resources Ltd. (“GBR”). GBR has reported over the past 2 years

company-building drill results with mineralized intersections commonly returning bonanza gold grades in

association with coarse visible gold grains. Portofino’s South of Otter Property is situated approximately

8 km east of GBR’s claims. In addition, GBR announced (September 9, 2020) the discovery of another

significant gold target called the “Sob el” in the Red Lake gold camp, located approximately 10 km

northeast of, and in the same greenstone belt as, the South of Otter.

The 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.
