NEWS RELEASE

PORTOFINO CLOSES ACQUISITION OF THE DRILL-READY

YERGO LITHIUM PROJECT BY WAY OF OPTION BUYOUT

Vancouver, B.C., September 26, 2023. PORTOFINO RESOURCES INC. (TSX-V: POR) (OTCQB: PFFOF) (FSE:

POTA) (“Portofino” or the “Company”) announces that further to its August 14-2023 news, it has closed

the buyout of the original Yergo Project Option agreements (Yergo Binding Letter Agreement - February

15, 2019, and the Binding Letter Agreement Addendum May 12, 2021).

Portofino now controls 100% of the mineral rights and concession ownership for the 2,932-hectare Yergo

Lithium Project (the “Project”) (see Figure 1 and 2) . This enables Portofino to advanc e its previously

submitted drill permit application and proceed thereafter with an initial, planned 4-hole drill program.

David Tafel, CEO of Portofino, commented: “We are very happy to finalize this transaction, as it secures

100% ownership of the Yergo Lithium Project concessions. Our team is looking forward to working with

the Ministry of Mining in Catamarca to expedite the drill permit application with a goal of initiating a

drill program this fall. Additionally, I would like to thank all involved in completing this transaction.”

Portofino’s exploration team believes the formation of lithium-bearing brines of both the Yergo Lithium

Project and Zijin’s 3Q Project may be related. H istoric volcanic activity located between the projects

may have been responsible for the generation of the Lithium-bearing solutions that are deposited in

the salar basins.

Figure 2: Yergo Lithium Project, Controlling 100% of the Aparejos Salar

Yergo Lithium Project, Catamarca Argentina:

The Project is 2,932 hectares in size , controlling the entire Aparejos Salar, located approximately 9

kilometers from the Salar Tres Quebradas (the “3Q Project”), previously developed by NeoLithium Corp.,

and acquired by Zijin Mining for C$960 million in 2022 (see: Zijin – 3Q Project)

Portofino previously completed and reported results of a geophysical survey identifying 2 large, aquifers

within the project measuring approximately 2.3km x 1km and 1.8km x 2.5km (POR News Release 06-APR-

2021). The Company’s surface sampling programs returned values up to 373 mg/l Lithium and 7,160 mg/l

Potassium with notably low Magnesium to Lithium ratios in the order of 1.51. This preliminary exploration

has advanced the project to a drill -ready stage. Portofino’s technical team has identified 4 priority drill

targets and a drilling contract has been finalized.
