RX Exploration Recommences Underground Test Mining Operations at Drumlummon Mine

RX Exploration Inc. (TSX-V: RXE) (OTCQX: RXEXF) ("RX Exploration” or the "Company”) is pleased to announce that with the completion of the new Gunsinger Decline, test mining operations have recommenced last week on both the Empire and the Charly Veins at the company’s 100%-owned Drumlummon Mine in Montana.

In addition, as part of its ongoing program to streamline mining efficiencies and costs, the Company’s wholly-owned Montana subsidiary, Drumlummon Gold Corp, has taken over all underground operations at the Drumlummon Mine from mining contractor, New Millennium Mining & Contracting LLC effective April 16, 2011. RX extends their thanks to New Millennium and their crews for their contribution over the past two years in the successful re-opening of the Drumlummon.

Drumlummon Gold Corp has assembled an experienced mining crew, complete with mine supervisors, safety managers, mine rescue capabilities sufficient to support two rescue teams, as well as maintenance and construction support crews.

"It is gratifying to see how quickly we were able to transition from contractor-driven development mode to the resumption of actual test mining with our own forces” commented Murray Nye, President of RX Exploration. "I am looking forward to the resumption of milling operations with its attendant cash flow, especially given the higher gold and silver prices presently available”.

RX Exploration has completed major modifications to the ventilation system and upgraded the haulage roads. Initial cross-cuts were driven to provide access to the 600 level of the Empire Vein and to the 570 level of the Charly vein.

Excavation of gold/silver vein material started this week with a program of silling-out both the Empire and the Charly veins in preparation for stope development. The excavated material is being stockpiled on surface and will be trucked for processing to one of the two local gold/silver mills that are providing toll milling services. Milling is expected to start by June 1, 2011, and should proceed on a continuous basis thereafter.

Simultaneously, development headings are being driven to gain access to the D Block south pillar on both the 400 and 500 foot level. As operations are ramped up, the Company intends to develop the 450 level as well. Drifting along mineralized vein material on these levels in the D Block zone will also confirm previously released diamond drill results (see RX News releases dated March 15, 2011 and March 30, 2011).

RX Exploration plans to ramp-up this test-mining program to reach a rate of 500 tons per day by the end of August.

Detailed sampling and assaying of the exposed faces during the silling-out program combined with actual metal recoveries from the milling program will provide additional information as to the grades, continuity and metallurgical recoveries of gold and silver values in the vein systems. An aggressive underground core drilling program continues with two contracted electric-hydraulic rigs testing the Empire and Charly veins below the 600 level and a company-owned, air powered drill testing the north end of the Drumlummon vein both above and below the 600 level.
