Portofino mobilizes crew to Allison Lake North lithium property near Red Lake

PORTOFINO RESOURCES INC. has mobilized a geological crew to the Allison Lake North lithium and rare elements.  The Property comprises 1,618 hectares (ha) and is located 100 kilometers (“km”) east of the town of Red Lake in northwestern Ontario.  The Property is accessible by well-established logging roads and a hydro-electric power line transects the claim group. The geological crew has commenced mapping and sampling on the property.

David Tafel, CEO of Portofino Resources states; “Securing strategic national supplies of critical metals such as lithium and rare elements is being prioritized by Canadian and U.S. governments. The Allison Lake region has been identified by the Ontario Geological Survey as an important new exploration target area for lithium and rare-element mineralization and we are excited to have “boots on the ground” and our exploration program underway.”

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 (Figure 1).

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”.

Based upon samples analyzed and included in the Breaks report, the outer rim of the Allison Lake batholith possesses anomalously high concentrations of rare elements including lithium (“Li”). 

Northwestern Ontario is host to several well-known Li and rare earth elements deposits that have delineated resources and preliminary economic assessment studies (Figure 2).  Of note is the PAK Li deposit along the ‘Electric Avenue’ which contains one of North America's highest-grade, large tonnage hard-rock Li resources. The PAK deposit has a mineral reserve in the proven and probable categories of 5.77 MT averaging 2.06% Li2O. The Spark Deposit, located 2.5km northwest of the PAK, was winner of the “2019 Discovery of the Year Award”. Frontier Lithium recently announced drill results from the Spark Deposit with hole PL-048-21 reporting 340 metres of 1.68% Li2O (TSX-V: FL news - June 1, 2021).
