RX Continues To Hit High Grade Gold and Silver Veins at Drumlummon Mine

August 5, 2008

Toronto, Canada - RX Exploration Inc. (“the Company”) is pleased to release further assay results from its underground diamond drill program at the Drumlummon Mine at Marysville, Montana. The drilling intersected the newly discovered Charly Vein, as well as other numerous and parallel high grade gold and silver veins in this “bonanza”- type epithermal deposit.

Following are significant intersections (length/grade gold multiples greater than 1) which were all drilled from the 400 foot level of the mine. There are numerous other lower grade sections in the same holes. True widths of the intersections have not yet been determined. The Company is awaiting a large number of assays.

DDH’s 08 – 9, 10 and 13 were drilled from Drill Station 2 while DDH’s 08 – 27, 28 and 29 were drilled from Drill Station 3, 200 feet north of Drill Station 2, to test the strike extension of the multiple vein structures encountered at Drill Station 2.

This structure continues to be are open at both ends along strike as well as at depth. The underground drill has been moved to Drill Station 4 where 9 holes are planned to test the south extension of the Charly Vein to a strike length of 650 feet. Drill Station 5 will be set up to test the Christmas Vein. The Drumlummon ceased production in 1950 when the mill was totally destroyed by fire. Historical records indicate that a significant portion of the Christmas Vein on the 800 foot level was ready for production at the time of the fire. Resource estimates have been presented by prior operators which are not in compliance with the current requirements found in National Instrument 43-101 and accordingly cannot be reported at this time. Mike Gunsinger, Director of Underground Operations, stated that “the Charly Vein and the Christmas Vein line up pretty well and the drilling at Drill Stations 4 and 5 are intended to determine if indeed the two veins come togeth er”.

Tom Gignoux is the consulting geologist supervising the drilling at the Drumlummon Mine. He is a qualified person within the meaning of National Instrument 43-101 and is responsible for the technical information contained in this news release. The core from the drill holes have been under his supervision from the time they were brought out of the mine. They are currently in secured containers on the Drumlummon property. Assays were performed by Robert W. Prather, Anaytical Chemist, of Norris Lab, Norris Montana, using the fire-assay method. Rejects of higher grade assays are being sent by Mr. Gignoux to Swastika Labs, Swastika, Ontario for check assays.
