Portofino Resources Inc. announced that it has received results from a property wide high-resolution helicopter-borne magnetometer ("mag") geophysical survey completed by Prospectair Geosurveys, on the Allison Lake North property (the "Property"). The survey comprised 406 line-kilometers of high-resolution mag with GPS controlled 50-meter line separations. The objective of the survey was to identify structural weaknesses, geological contacts and possible fractionation directions in the Allison Batholith that could potentially contain lithium bearing pegmatites.

The resultant total magnetic intensity field was very settled in absolute terms with increasing intensity towards the eastern portion of the Property (Figure 1). This may represent fractionation westward from a barren biotite-rich granite to a more peraluminous fertile granitic melt. Low amplitudes in the southwestern portion of the Property may reflect metasediments of the Birch-Uchi greenstone belt.

According to Breaks et al., 2003, fractionation and crystallization or rare elements (Li-Cs-Ta) occur mainly at the outer edges of the parental granite or those rocks in contact. Preliminary interpretation of the survey results will aid in the next phase of ground prospecting and mapping to those areas of high merit when combined with Portofino's previous sampling and mapping efforts.
