RPT Uranium Corp. Sibley Basin Project Update

VANCOUVER, BRITISH COLUMBIA--(Marketwire - Sept. 27, 2007) - Dr. Hikmet Akin, president of RPT Uranium Corp. (TSX VENTURE:RPT), the largest land holder in the Sibley basin northeast of Thunder Bay, Ontario, is pleased to give the following summary of recent exploration activities on the company's 90,000 hectare (222,000 acre) uranium property.

A summer diamond drilling program has been carried out on the Split Rapids Zone where uranium occurs in veins and fractures in an adjacent to a 900 metre length of Archean iron formation. The Archean rocks are believed to lie a short distance below the unconformity at the base the Sibley sediments, which have been removed by erosion at that point. Thirty-three holes were drilled, totalling 3,827 metres. Seventeen mineralized zones were sampled; no assays have been received to date.

A program of power stripping is under way on a group of uranium occurrences located by prospecting on the Malborne Lake claim group. Stripping is complete on the Frazer Creek showing, where radioactivity has been found over an area measuring 80 metres by 90 metres. The main Frazer Creek showing consists of almost continuous radioactivity over a 40 metre by 30 metre area, which is open to the east where it disappears under heavy overburden and wet swamp. Mineralization is associated with hematized breccia zones and hematite-coated fractures in and adjacent to north-south faults and fractures. The host rock is an Archean greywacke-type metasediment. No assays have yet been received from samples collected during the stripping.

Stripping is continuing on other zones north of the Frazer Creek showing. Prospecting around Malborne Lake has located 14 separate radioactive occurrences over a 4 kilometre length. They define a trend that is roughly parallel to prominent topographic features believed to reflect Proterozoic age faults.

The company has contracted with Fugro Airborne Surveys for a radiometric-magnetic-EM survey over the Malborne Lake claims and the recently staked 24,000-hectare Dorion claim block. Most of the area to be surveyed is underlain by Archean rocks from which the Sibley sedimentary cover has been removed by erosion. The survey is expected to commence within the next 20-30 days.

Diamond drilling will resume once all assay results from the 2007 drilling and stripping programs have been received and compiled.
