Portofino Reports Issuance of Environmental Resolution Enabling Drilling and Exploration- Yergo Lithium Project, Argentina

Vancouver, British Columbia--(Newsfile Corp. - August 23, 2022) - PORTOFINO RESOURCES INC. (TSXV: POR) (OTCQB: PFFOF) (FSE: POTA) ("Portofino" or the "Company") is pleased to announce that an official Resolution (the "Resolution") from the Minister of Water, Energy and Environment of Catamarca province has been issued. The Resolution includes reference to an underlying report that details commercial activity guidelines within the southern part of the province and authorizes exploration and drilling at the Yergo Lithium Project (the "Project"). The Resolution issuance has been deemed to be the Mining Ministry's last requirement pursuant to approval of Portofino's planned exploration and drilling programs.

David Tafel, CEO of Portofino, commented: "Portofino has established rigid procedures within its planned exploration program to achieve the highest standards of environmental sustainability. In addition, and as previously confirmed by the Mining Ministry, the issuance of the Resolution was the final requirement needed for the Ministry to grant a drilling permit for the Project. We can now expect the Mining Minister's office to advance our permit application without further delay."

The drilling permit application proposes to implement an inaugural 4-hole drill program. A previously completed geophysical survey and surface geochemical sampling program identified two large, lithium-bearing sub-basins within the Yergo Project (April 06-2021). The survey and sampling results confirm the presence of lithium-rich brines and the potential volume of the brines within the Project.

The 2,932 hectares Yergo Project encapsulates the Aparejos Salar and is located in the southern part of Argentina's world-renowned "Lithium Triangle". The project is situated 15 kilometers southeast of Neo Lithium Corp's 3Q Project. (In January 2022, Zijin Mining Group Co. completed a $960 million takeover of Neo Lithium Corp.)
