New Opportunity * New Horizon

1. Platinex Inc. TSX-V: PTX New Opportunity * New Horizon Prepared on 06/01/07

2. Platinex Inc. TSX-V: PTX • Platinex Highlights • Explore for Multi-Million oz PGE deposits (e.g. Bushveld) • Control 4,889 Ha of claims and leases over Big Trout Lake (BTL) layered intrusions in Northern Ontario • BTL Complex: • 500 m thickness of ultramafics; • identified 17 chromitite layers • PGE Intercepted: • 8.3 g/t PGE over 2.3 m in previous drilling • 310 intercepts over 1 gm Pt+Pd+Au • Six Drill Ready PGE Targets and chromium deposits have been identified - 7,225 m drilling planned

3. Platinex Inc. TSX-V: PTX • Platinex Highlights • Chromium drill program to substantiate previous results which includes conceptual model of 1.725 billion tonnes of 8.4% Cr2O3. • Metallurgical tests to evaluate characteristics of chromite, test recovery and processing techniques and conduct preliminary pilot studies. • Preliminary ore valuation of chromite deposits. Possibly 2-4 g PGE in chromite; relationship between chromite and PGE mineralization. • 17,000 feet of core drilled by INCO to be relogged and sampled for PGE for the first time at a total probable cost of $200,000 ( a cost saving of $1.3 million • High hit potential in the former INCO drill fences as both Merensky Reef equivalent and Main Sulphide Zone equivalent stratigraphy will be tested for the first time for PGE.

5. First Nations Issues Platinex has had a long and frustrating relationship with Kitchenuhmaykoosib Inninuwug (KI) – but has contract with local trapper and originally had consent of chief to proceed with exploration. KI blockaded Platinex, saboutaged airstrip, and pillaged campsite last Feb forcing a termination of a drill program - police and Ontario refused to enforce law. To gain access Platinex took KI to court. Judge in July refused Platinex's injunction but upheld KI injunction charging KI to immediately enter consultation with Platinex and Ontario (Based on irreversible harm to culture etc.) After months of court cases Judge has restored Platinex possession of claims and leases and proclaimed the Memorandum of Understanding and Consultation Protocol covering the first 24 holes of an 80 hole program. Judge will remain in the background to ensure that the parties agree and accommodate to enable Platinex to explore the property Platinex, KI and Ontario now in more cooperative consultation to establish agreement on further drilling while the current program is being conducted.
