NEWS RELEASE

PORTOFINO REPORTS SAMPLING RESULTS-RIO GRANDE SALAR, ARGENTINA

Vancouver, B.C., September 18, 2018. PORTOFINO RESOURCES INC. (POR: TSX-V) (POT: FSE) (“Portofino”

or the “Company”) is pleased to announce results from its 2018 exploration/evaluation program on the

Rio Grande Sur lithium brine project in Catamarca, Argentina . The exploration program included

geological mapping and pit and auger sampling of near-surface saline brines to depths down to 1 meter.

In total, 13 sample sites were tested within the project concessions with samples returning values of up

to 216 mg/L lithium (Li), and up to 4,185 mg/L potassium (K). All brine s amples were analyzed by Alex

Stewart Analytical Laboratory in Mendoza, Argentina.

The Company’s Rio Grande Sur concessions cover one of the primary water sources for the main Rio

Grande salar brines located immediately to the north. The results of the 2018 sampling program indicate

that there are locations where Li is being concentrated (up to 216mg/L) on the Property. Of interest to

the Company is the presence of Li in spring -sourced surface waters, which indicates that this area may

also be a key source of Li for the salar.

The Rio Grande Sur project comprises 3 mineral concessions totaling approximately 8,500 hectares and

consolidates the southern extension of the Rio Grande salar in Catamarca. The property is adjacent to the

Rio Grande concessions held by LSC Lithium Corp. (“LSC”) wherein LSC has reported an initial Mineral

Resource estimate*.

David Tafel, Portofino’s CEO stated: “The initial due diligence sampling program has been successful in

identifying specific areas within the concession to focus the next stage of our exploration which will

involve generating drill targets to test the project at depth.”
