Trading Symbol RCR: TSXV

TORONTO, Sept. 15, 2011 /CNW/ - Rockcliff Resources Inc. (RCR: TSXV) is pleased to announce that its 3,000m diamond drill program on its Snow Lake Project in Manitoba has been increased to 4000m and prospecting and trenching has identified visible gold and extended the WK gold zone on its Black Gold property in Kirkland Lake, Ontario.

Snow Lake Project Drill Program:

At the Rail Property, two holes have been completed testing deep geophysical targets along strike of the Rail Copper Deposit, an NI 43-101 compliant resource (Indicated Resource of 822,000T grading 3.04% copper, 0.90% zinc, 0.66g/t gold, 9.25g/t silver.  Mineral resources are not mineral reserves and do not have demonstrated economic viability).  Drill samples have been sent to the assay lab and will be announced when available.  A third hole is presently in progress south of the Rail Deposit testing an off-hole conductor measuring 400m long by 250m high.  The nearest hole (RL10-56) to the conductor intersected 4.1m grading 5.1% copper, 0.6g/t gold, 0.2% zinc and 7.3g/t silver.

Drilling at the Tower property will commence shortly.  Two untested geophysical conductors (T-3 and T-1B) located proximal to the Tower Deposit are planned to be tested.  The T-3 conductor is located 800m west of the Tower Deposit.   It has a strike length of over 1 km and has very similar geophysical characteristics to the nearby Tower Deposit.  The Tower Deposit has intersected pervasive copper mineralization over a strike length of 700m and to a vertical depth of over 400m.  The deposit remains open in all directions and has intersected high grade VMS mineralization including 8.2m grading 7.6% copper, 2.0g/t gold, 1.7% zinc and 35.4g/t silver (hole 8) and 4.9m grading 6.1% copper, 1.6g/t gold, 2.0% zinc and 35.9g/t silver (hole 21) as reported in the Press Releases dated March 1 and May 17, 2011.

Black Gold Property Trench Program:

Trenching of the original WK Gold Zone on the Black Gold Property has uncovered visible gold and disseminated pyrite within a shear zone hosted quartz stockwork system.  Exploration has outlined the zone to a known strike length of approximately 75m with widths ranging between 2 and 8m wide.  The zone is located along the western limit of an Induced Polarization (IP) anomaly striking for over 300m.  The remainder of the anomaly is covered by deeper overburden.  Over 40 samples of the mineralized zone have been sent for assay and will be announced when available.  Prospecting and geological surveys are presently in progress on underexplored areas of the property.

Rockcliff has the exclusive right to earn a 70% interest in the Tower Property from Pure Nickel Inc. (NIC: TSX).  Rockcliff must pay $150,000 in incremental payments over four years and will be required to incur aggregate exploration expenditures totalling $4,000,000 over four years.  Please refer to the Press Release dated February 28, 2008 for further details.

Rockcliff has the exclusive right to earn a 100% interest in the Rail Property from Hudson Bay Exploration and Development Company Limited (HBED), a wholly owned subsidiary of HudBay Minerals Inc. (HBM: TSX). If Rockcliff earns its interest in the Rail Property, HBED will receive a 2% Net Smelter Return Royalty in the property. If Rockcliff earns a 100% interest in the Rail Property, HBED then has a right to acquire up to a 65% interest in the Rail Property. Please refer to the Press Release dated March 23, 2007 for further details.
