JUN-2019 TSX-V : POR 13 Project II: Catamarca Province, Argentina

• Portofino can acquire up to an 85% interest in Project II, a lithium brine property, which is located approximately 10 km from the Chile border, 27 km east of Wealth Minerals’ Laguna Verde project and 65 km northeast of Neo Lithium Corp’s 3Q project, encompassing a 3,950 ha claim block. • Historical exploration work commissioned in 2012 by the vendor included geological mapping, sampling of surface waters, auger sampling of brines, and compilation of the distribution of Lithium and Potassium grades within the basin. Surface water and auger brine samples were analyzed and results averaged 274 mg/l of Lithium. June 2017 APEX Geoscience undertook a comparative surface sampling program that validated the results received in 2012.
