NEWS RELEASE

PORTOFINO TO COMMENCE GEOPHYSICAL SURVEY

HOMBRE MUERTO SALAR-ARGENTINA

Vancouver, B.C., Feb 26, 2019. PORTOFINO RESOURCES INC. (POR: TSX-V) (POT: FSE) (“Portofino” or the

“Company”) is pleased to announce the selection of a geophysical team that has been engaged to

complete surveys at the Company’s Hombre Muerto West Project (the “Project” or the “Property” ),

located on the western side of the Salar del Hombre Muerto in the Catamarca Province of Argentina. The

geophysical survey work is intended to follow up on encouraging Lithium (and Potassium) results achieved

during last year’s near -surface brine sampling program ( see News Release - July 10, 2018) . The

geophysical program will help to define the extent of brines in the sub-surface at the Property, which will

in turn be used to define targets for planned exploration drilling. The geophysical team is expected to

mobilize to site in early March.

The Company’s 2018 exploration program at the Hombre Muerto West Project comprised the collection

of 18 near-surface brine samples that were submitted for geochemical analysis at the Alex Stewart

Analytical Laboratory in Argentina. The best result from the 2018 brine sampling program was a sample

that returned values of 1,031mg/L lithium (Li), 9,511 mg/L potassium (K) and 1,716 mg/L magnesium (Mg).

The overall average of the eighteen analyses was 384.4 mg/L Li and 3,848.2 mg/L K. (News Release - July

10, 2018).

The Company also reports that it has engaged an experienced Argentine group (comprised of geologists,

biologists, archeologist, and naturalists) to commence an Environmental Impact Study (“EIS”) for the

Hombre Muerto West Project . The study is required by the provincial government and will include

discussions of the geological and hydrogeological characteristics of the Project area , the flora and fauna

of the region, sites of historical value, climate, proposed work p lans and proposed impact mitigation

measures. The results of the 2018 near -surface brine sampling program will also be submitted to the

provincial mining authorities as part of the EIS and to support other permit applications which are now

underway.
