TORONTO, June 2, 2011 /CNW Telbec/ - Rockcliff Resources Inc. (RCR: TSXV) is pleased to announce that a recently completed surface DPEM geophysical survey over the high grade Tower Copper Deposit has identified potential extensions of the deposit and a new "priority one" massive sulphide anomaly adjacent to the deposit. The Tower Deposit is a high grade copper deposit within a newly defined twelve km long VMS corridor located within the property. Rockcliff's next drill program at Tower will target the deposit and its extensions and the adjacent massive sulphide anomaly.

The DPEM survey outlined the Tower Deposit as having a north-south strike length of approximately 700m, a steep easterly dip and a steep northerly plunge to significant depths of at least 700m vertical. Rockcliff's recently completed drill program tested the deposit to a vertical depth of 300m. Potential extensions north and south of the deposit were also identified in the survey.

The DPEM survey also discovered the T-3 massive sulphide anomaly along the flanks of a magnetic high and located approximately 800m west of the Tower Deposit. The T-3 massive sulphide anomaly mirrors the Tower Deposit in size, conductance and is north-south striking and east dipping. The T-3 anomaly has never been drill tested and has significant potential to host VMS mineralization similar to that of the Tower Deposit.

The DPEM report has been posted on Rockcliff's website at www.rockcliffresources.com.

To earn a 70% interest in the property, Rockcliff must pay $150,000 in incremental payments to Pure Nickel Inc. (NIC: TSE) over four years and will be required to incur aggregate exploration expenditures totalling $4,000,000 over four years; $2,000,000 over two years to earn a 50% working interest and a further $2,000,000 to earn a further 20% working interest.
