Winnipeg, Canada – RX Exploration Inc. (CNSX: RXE) (the “Company” or “RX”) is successfully advancing the exploration of the Drumlummon Mine, Marysville, Montana (the “Drumlummon”) on several fronts including underground exploration drifting and development, underground diamond drilling, and bulk metallurgical testing.

Drumlummon Exploration Drifting & Development

Charly Vein - The Company has now drifted in mineralization on the Charly Vein over a strike length of 186.2 metres (611 feet) on the 500 level of which a total of 14.9 metres (49 feet) at the two extremities are considered marginal grade. For planning purposes, the central 171.3 metres (562 feet) delineates the strike length of the Charly vein at this depth. The main internal exploration ramp is currently being driven to the 550 level to enable exploration drilling of the Xmas and Charly veins to depth.

A raise was established from 96 to 112 feet south of the Charly Vein North and South intersection (“Charly N-S”).  Sub-drifts were driven at the 470 level to the north and south from this raise.  Generally, the south sub-drift was found to have marginal grade/width, however high grade gold and silver values were encountered in the north sub-drift. The weighted average of channel samples across 13 consecutive faces of the north sub-drift was 75.87 grams per tonne (g/t) or 2.213 ounces per ton (“opt”) gold (“Au”) and 822.79 g/t or 23.998 opt silver (“Ag”) over an average true width of 2.2 metres (7.2 feet). The average includes a high of 449.49 g/t or 13.11 opt Au and 2036.23 g/t or 59.39 opt Ag over a true width of 1.5 meters (5 feet).

D-Block - Headings were driven from the main internal exploration ramp to intersect the D-block (114.3 metres or 375 feet west of the Charly) on the 450 level and on the 500 level.  A by-pass drift around a caved area on the old 500 level was driven to provide ventilation and a second escape-way to the 400 level from the lower levels for exploration drillers, geologists and development miners working below.

A total of 805.6 metres (2,643 feet) in development headings has been driven below the 400 level as of June 30, 2010. The accompanying chart summarizes the development headings and distances of each to June 30, 2010.

Underground Drill Stations

Previously, a 150 foot cross cut was driven east into the hanging wall of the Charly Vein on the 500 level to establish an underground diamond drilling station at the intersection of Charly N-S. A second cross-cut located 200 feet to the north was driven 45 feet east to establish a second drill station.

The ramp has been continued in a southerly direction at a -15 degrees slope towards the 550 foot level, where it is planned to establish a third drill station in the hanging wall from which drill holes will be able to test the Xmas vein.  Future plans call for the continuation of the ramp back to the north towards the 600 level to facilitate the establishment of hanging wall drill stations to enable further exploration of the Charly Vein at depth. Cross-cuts from the ramp to the Charly Vein will provide access to enable drifting along the vein itself on the 550 level and extraction of this material.

Bulk Metallurgical Test Program

Bulk testing of mineralized material from the Drumlummon (the “Feedstock”) continues at the milling facility in Philipsburg, MT (the “Mill”). The purpose of this program is to optimize metallurgical recoveries and fully develop the metallurgical flow sheet.

From June 16 to June 30, 2010, a total of 1,926.9 tons of Feedstock was milled bringing the total tonnage processed at the Mill to 4,453.94 tons up to June 30, 2010. The average daily throughput during the June 16-30 period was 175 tons per day (“tpd”). Concentrates from the bulk metallurgical testing program at the Mill were delivered to smelter brokers and refiners, yielding settlement quantities totaling 1,206 oz Au and 33,717 oz Ag. Net smelter return cash value of this quantity at prevailing prices is calculated to total US $1,985,100 of which US $1,766,063 is attributable to concentrate produced during the month of June.

Mill feedstock was derived from a blend of development headings on the Charly Vein and from lower grade gob backfill and sloughed wall rock mucked from old stopes above the 400 level of the Drumlummon vein.  Recoveries to date (based on settlement metal quantities) are calculated to be 88.43% for gold and 86.92% for silver. Minor variations in the mill flow sheet are being considered in order to further optimize mill recoveries for different ore types.

Quality Control/Quality Assurance (QC/QA)

Underground face samples, AX core and mill samples are fire assayed at the Company’s in-house laboratory.  All drill core is logged, photographed, and cut in half with a diamond saw.  One half is bagged and sent for assay, while the other half is archived and stored on site. N sized core samples are sent to an outside lab for assaying. Duplicates of 25% of the N core samples and selected duplicate samples from the in-house lab are sent to ALS Chemex Lab, Elko, NV for verification assaying. For QC/QA purposes standards, blanks, and repeats are randomly inserted into the sample stream.
