CAD$1.2 Million Exploration Program Planned to Commence in July

Trading Symbol RCR: TSXV

TORONTO, July 7 /CNW/ - Rockcliff Resources Inc. ("Rockcliff") (RCR: Tier 1 TSXV) is pleased to announce that a National Instrument (NI) 43-101 Technical Report has been completed for its Gold Dust Property located in central Manitoba west of Rockcliff's Snow Lake Project. The report was completed by Karen J. Ferreira, M.Sc., P.Geo. of Winnipeg, Manitoba. The entire report dated May 15, 2010 and titled "Technical Report on the Gold Dust Property, North-Central Manitoba, Canada" can be viewed at In addition to the Gold Dust Property which presently hosts two gold deposits including the former producing Century Gold Mine, the Snow Lake Project covers over 600km(2) and includes four historical VMS deposits rich in copper, zinc, silver and gold as well as other untested VMS and precious metal targets. The Snow Lake Project is strategically located within the Flin Flon greenstone belt, one of the most prolific and the largest Paleoproterozoic VMS district in the world.

Ferreira concluded the Gold Dust property is prospective for gold and holds potential for the discovery of quartz-vein-hosted gold mineralization associated with the Elbow Lake Shear Zone. The Elbow Lake Shear Zone is a prominent 20 km long, protracted deformation corridor which provided a favourable conduit for prolonged movement of gold bearing mineralized fluids that were the source of vein-type gold mineralization on the property. The property hosts the former producing Century Gold Mine, the "C" Zone Deposit and eight known historical gold showings as well as several other unnamed showings and drill core intersections with significant gold assays up to 340 g/t gold. The Century Deposit hosts an historical resource of 311,000 tonnes grading 5.6 g/t gold. The "C" Zone Deposit has an unpublished historical resource of 42,000 tonnes grading 2.8g/t gold. Although the historical estimates of grade and tonnage given in this news release are viewed as relevant based on the information and methods used at the time, they do not satisfy the requirements set out by NI43-101 and must be considered only as historical resources. Neither Rockcliff nor Ferreira has carried out sufficient work to classify the historical estimates under current mineral resource or mineral reserve terminology. The historical estimates are not meant to be interpreted as current estimates as defined in sections 1.2 and 1.3 of NI43-101 and should not be relied upon.

Rockcliff proposes and Ferreira recommends a two-phase exploration program totalling ~CAD$1.2 Million. The program includes 810 line kilometres of airborne geophysics covering the entire Gold Dust property, linecutting and an Induced Polarization (I.P.) Survey and up to 5,000m of diamond drilling. These recommendations are planned to commence in July with initial ground prospecting/mapping, airborne geophysics and surface geophysics to be completed by the third quarter of 2010.

The information in this news release has been reviewed and approved by Karen J. Ferreira, M.Sc., P.Geo, a Qualified Person in accordance with the Canadian regulatory requirements as set out in NI43-101.

Presently, Rockcliff is preparing to commence exploration at the Tower Property. Please refer to the Company's news release dated June 9, 2010 and titled "Rockcliff Plans Summer Exploration at the Tower Property" for additional information.
