Platinex Files Technical Report for Norton Lake Property

TORONTO, ONTARIO--(Marketwire - May 20, 2011) - Platinex Inc. (TSX VENTURE:PTX), announced the filing of a qualifying report covering its Norton Lake property.

Platinex's Norton Lake property comprises 56 claim units for 907 hectares. The property is located within two kilometres of the Norton Lake Ni-Cu-PGE deposit. The Norton Lake property is on strike with the rocks hosting the Norton Lake deposit and two anomalies on the property exhibit a similar magnetic signature to the deposit. Platinex intends to further investigate the magnetic anomalies.

James Trusler, Platinex's President & CEO commented, "While Platinex's current exploration focus is on its Shining Tree Gold Property, our six PGE properties represent tremendous long term value for the Company's shareholders. Our objective with the PGE properties, including the Norton Lake project, is to finance the development of the properties through farm out agreements and the filing of the qualifying reports is part of that overall process."
