NEWS RELEASE

PORTOFINO UPDATES LITHIUM PROJECTS STATUS IN CATAMARCA, ARGENTINA;

FRANKFURT STOCK EXCHANGE LISTING

Vancouver, B.C., October 17, 2017. PORTOFINO RESOURCES INC. (POR: TSX-V) (POT: FSE) (“Portofino”

or the “Company”) announces that it intends to amend a Letter Agreement announced on March 29,

2017 to acquire an 85% interest in two lithium brine salar projects in Catamarca, Argentina. Further to

discussions with the concession owner and its due diligence, the Company is finalizing details to an

amended agreement and intends to advance to a definitive agreement with one of the two projects

originally announced. The Company will proceed with Project (#2) which is approximately 3,900 hectares

in size. It is located 10 kilometres (“km”) from the Chile border and situated between Neo Lithium Corp’s

3Q project to the south-west and the Antofalla salar currently being developed by Albermarle

Corporation to the northeast.

Historical exploration work commissioned by the concession owner in 2012, included geological

mapping, sampling of surface waters, auger sampling of brines, and compilation of the distribution of

lithium (“Li”) and potassium (“K”) grades within the basins. A number of surface water and auger brine

samples were analyzed and results averaged 274 mg/l of Li and 7,521 mg/l K. Catamarca province,

located within the prolific “Lithium Triangle” produces more lithium than any other province in

Argentina.

The Company and its Qualified Professionals have not verified the historical sample collection

methodology or analytical results, but believe the results are relevant. Future work by Portofino,

including a surface water and auger brine sampling program is required to verify the historical results.

To earn its interest, Portofino has agreed with the concession owner to make a series of escalating cash,

shares, and expenditures over a 4-year period. The financial terms are expected to be similar to the

previously agreed schedule.

The Company is also making progress on a definitive agreement pursuant to its news release of

September 7, 2017, whereby the Company announced a 100% earn-in option on the Del Condor and

Pucara projects located within the Salar del Hombre Muerto, where FMC Lithium is currently producing

lithium carbonate and Galaxy Resources is developing its Sal de Vida project. In addition, the Company is

in advanced discussions with other lithium brine concession owners within the Catamarca, Argentine

lithium triangle region.

Frankfurt stock exchange listing

Centurion also announces that it has obtained a listing on the Frankfurt stock exchange and the Company

has commenced trading under the symbol (“POT”).
