TORONTO, ONTARIO--(MARKET WIRE)--Mar 4, 2008 -- RX Exploration Inc. ("the Company")(CNQ: RXEX) is pleased to announce that it expects to begin this week its 20,000 foot underground diamond drill program at the Drumlummon Mine at Marysville, Montana, one of the larger former producers of gold and silver in the Western United States. The Drumlummon is of the "bonanza"- type epithermal deposits which are very young and low temperature in origin and which can produce high grades over large widths. Drilling will be conducted from recently rehabilitated sections of the 400 foot level of the mine. Resource estimates have been presented by prior operators which are not in compliance with the current requirements found in National Instrument 43-101. The intent of this drill program, and follow-up drill programs as required, is to establish mineral resources on a NI 43-101 compliant basis with respect to the substantial undeveloped sections within the Drumlummon Mine and extensions thereof, leading to a preliminary feasibility study.

The Company is also pleased to report that its website www.rxexploration.com is now operational. Persons desiring to receive copies on the Company's press releases when issued are invited to provide their e-mail particulars through the website. The Company intends to provide drill results on a regular basis over the course of the program.

The Company will be exhibiting at booth number 2533 (Gossan Resources booth) at the Prospectors and Developers Association convention in Toronto on Tuesday and Wednesday of this week.
