Vancouver, British Columbia--(Newsfile Corp. - June 29, 2021) - PORTOFINO RESOURCES INC. (TSXV: POR) (OTCQB: PFFOF) (FSE: POTA) ("Portofino" or the "Company") is pleased to provide an update to the Company's June 23rd news release announcing the mobilization of our geological crew to the Allison Lake North lithium and rare elements property ("Property"). Portofino's geologists have encountered several granitic pegmatite outcrops in recently logged areas of the property enabling the team to immediately initiate a channel sampling program across these exposures (Photo 1). The Allison Lake granitic pegmatites are known to be enriched in lithium and other rare elements as established by the 2003 Ontario Geological Survey ("Breaks") report.

Channel sampling is the best way to take representative samples over broad zones where the mineral grain size can be large, and the pegmatites found on the Property can contain mineral grains measuring several centimetres. In addition, field identification of such minerals as beryl (Beryllium-silicate) and tourmaline (Boron-silicate), which can be intimately associated with economic rare element mineralization, support Portofino's objective of finding an economic deposit containing these important elements.

The Company's website contains additional exploration pictures that can be viewed at: Allison Lake North Property Sampling. Channel samples and selected grab samples will be submitted to an accredited laboratory for chemical and mineral analyses. The results will be released when available.

The Allison Lake North Property

The Property comprises 1,618 hectares (ha) and is located 100 kilometers ("km") east of the town of Red Lake in northwestern Ontario. It is accessible by well-established logging roads and a hydro-electric power line transects the claim group. The Property contains significant attributes that are key to the formation of lithium-bearing pegmatite dykes. It is positioned along the contact between the Allison Lake pegmatite granite batholith and the Jubilee Lake metasedimentary rocks of the Uchi Subprovince in northwestern Ontario.

The 2003 Ontario Geological Survey (Breaks) report described the Allison Lake batholith as the largest known peraluminous granitic body in northwestern Ontario. Breaks concluded that "the Allison Lake batholith represents an important new exploration target for rare-element mineralization and is the largest such granite thus far documented in Ontario. This area has high potential for further discoveries of rare-element mineralization."

Northwestern Ontario is host to several well-known Lithium and rare earth elements deposits that have delineated resources and preliminary economic assessment studies (Figure 1).
