lithium brine project in Catamarca, Argentina. A total of 18 sample sites were tested within the project

concessions and the highest-grade sample returned 1,031mg/L lithium (Li), 9,511 mg/L potassium (K) and

1,716 mg/L magnesium (Mg). The overall average of the eighteen analyses is 384.4 mg/L Li and 3,848.2

mg/L K. The average magnesium ratio relative to lithium is 1.99.

The exploration program included geological mapping and near-surface auger and pit sampling of saline

brines to depths of 1 to 1.5 meters.

“We are very encouraged with the multiple high-grade lithium results and the relatively low magnesium-

lithium ratios from this sampling program . The outstanding success of this initial work program gives

credence to our next phases of exploration activity which are anticipated to include geophysical surveying

and drilling” stated David Tafel, Portofino’s CEO.

The Company further reports that additional exploration results are anticipated shortly for similar

programs conducted on its Rio Grande and Project II properties.
