PORTOFINO RESOURCES RIO GRANDE SUR CLAIMS

LSC – Rio Grande Salar

• Portofino has the right to acquire up to a 100% interest in the Rio Grande claims. The concession area comprises approximately 8,500 ha, 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") and EnirgiGroup Corp. ("Enirgi")

• LSC has reported an initial Mineral Resource estimate* within its concessions which included a total of 2,190,000 tonnes of lithium carbonate (Li2CO3) equivalent in the Inferred Mineral Resource category with the top 50 meters (“m”) of the deposit amounting to 1,375,435 tonnes grading at 338mg/l Li and the lower 50m to 100m amounting to 814,582 tonnes grading at 410mg/l Li.

*LSC Lithium Corp. “Technical Report on the Salar de Rio Grande Project, Salta Province, Argentina” dated March 28, 2018 and authored by Hains Engineering Company Limited.

PORTOFINO RESOURCES PROJECT II CLAIMS

Wealth Minerals – Laguna Verde

• 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. As a result, Portofino intends to move forward with a definitive agreement on the property and to initiate a formal exploration program.
