TORONTO, May 11 /CNW Telbec/ - Rockcliff Resources Inc. (RCR: TSXV) is pleased to announce that a recently completed 1700 line kilometre
airborne VTEM survey on its Snow Lake Project has successfully
identified significant geophysical anomalies worthy of follow-up
exploration. The anomalies are interpreted to be VMS hosted targets
and were identified at the Tower, Dickstone Copper and Dickstone North
properties. Geological ground proofing followed by surface gridding
and ground geophysics will determine the priority sequence for future
drill target evaluation. The Snow Lake Project is centered within the
prolific Flin Flon greenstone belt, one of the most prolific VMS
districts and the largest Paleoproterozoic VMS district in the world.
All VMS mines in the Flin Flon and Snow Lake camps are hosted in
juvenile arc rocks.


At the Tower property, six geophysical anomalies were identified in the
survey. One of the anomalies corresponded to the high grade copper
Tower VMS Deposit. All six anomalies are associated with a 12 km long
geological trend now interpreted as a potential "VMS-rich corridor".
The VMS anomalies range from 400m to 1500m long and are located along
the edge or centered on magnetic highs. Rockcliff is earning a 70%
interest in the Tower property from Pure Nickel Inc. (NIC: TSE).


At the Dickstone Copper property, three geophysical anomalies were
identified in the survey. One of the anomalies corresponded to the
former producing Dickstone copper-zinc mine. All three anomalies are
associated with the favourable "mine trend geology" (juvenile arc
rocks) which strikes across the property for a distance of seven km.
The VMS anomalies range from 200 to 300m long and are located along the
edge or centered on magnetic highs. Rockcliff is earning a 100%
interest from Xstrata Copper Canada, a division of Xstrata Canada
Corporation (Xstrata).


At the Dickstone North property, two geophysical anomalies were
identified in the survey. Both anomalies are associated with juvenile
arc rocks. The VMS anomalies range from 200 to 400m long. One anomaly
is located along the edge of a magnetic high while the other anomaly is
located on a magnetic high. Rockcliff owns 100% of the Dickstone North
Property. The property lies immediately north of the Dickstone
copper-zinc mine.


The airborne VTEM survey utilized Geotech's versatile time-domain
electromagnetic (VTEM) and high sensitivity, cesium vapour magnetometer
systems over the properties. The VTEM system has excellent depth
penetration and high spatial resolution capabilities along with
superior resistivity discrimination for detection of weaker anomalies.
