Silver Results

Trading Symbol RCR: TSXV

TORONTO, Aug. 18 /CNW/ - Rockcliff Resources Inc. (RCR: Tier 1 TSXV) is pleased to announce that initial prospecting and rock grab sampling at the Gold Dust Property has confirmed the presence of widespread gold and silver values on the property. Prospecting and sampling at Gold Dust will continue into the late summer and fall exploration season. High grade surface grab samples up to 60.8 g/t gold and 154.4 g/t silver have been identified in sulphide rich quartz veins hosted by altered mafic volcanic and quartz feldspar porphyry rocks.

Rockcliff's President and CEO commented, "The Gold Dust Property is a district scale property with significant and widespread high grade gold and silver values. It is a bona fide gold play in the heart of a world class VMS camp and is located west of HudBay's Lalor Deposit where exceptional gold results continue to be intersected. Our initial high grade results will now allow us to increase our gold exploration efforts over the coming months on this exciting gold property."

A total of 172 rock grab samples were collected at Gold Dust under the current program. A general geology map outlining the location of the historical showings presently being sampled can be viewed at www.rockcliffresources.com. At Gold Dust, gold is generally associated with sulphide-hosted quartz veins within fault splays bounded by sheared mafic volcanic and quartz feldspar porphyry rocks adjacent to a major regional shear zone (Elbow Lake Shear Zone). The Bow Vein samples (66 in total) were collected over a 100m strike of the vein. The Bow Vein has been traced historically a distance of approximately 300m and remains open along strike and at depth.

The Gold Dust property presently hosts 2 gold deposits (Century and C Zone) associated with gold horizons which have been traced collectively a distance of over 20 km. Rockcliff is earning a 100% interest in the Gold Dust Property which forms part of its Snow Lake Project located in central Manitoba (please see Rockcliff's news release dated November 24, 2009 for additional information).

Ken Lapierre P.Geo., President and CEO of Rockcliff Resources Inc., a Qualified Person in accordance with Canadian regulatory requirements as set out in NI 43-101, is responsible for the information in this press release.

QA-QC Statement

Ken Lapierre P.Geo., President and CEO of Rockcliff, is responsible for verification and quality assurance of Rockcliff's exploration data and analytical results. Samples are packaged and shipped directly from Rockcliff's field office to TSL Laboratories (TSL), Saskatoon, Saskatchewan. TSL is a Canadian assay laboratory and is accredited under ISO/IEC 17025. Each sample is dried, crushed to 70% passing 10 mesh and a 250g pulp is pulverized to 95% passing 150 mesh for assaying. A 0.5g cut is taken from each pulp for base metal analyses and leached in a multi acid (total) digestion and then analyzed for copper, lead, zinc and silver by atomic absorption. Gold concentrations are determined by fire assay using a 30g charge followed by an atomic absorption finish. Samples greater than upper detection limit (3000 ppb) are reanalyzed using fire assay gravimetric using a 1 AT charge. Rockcliff inserted certified blanks and standards in the sample stream to ensure lab integrity.
