Rockcliff Options Tower VMS Property From Pure Nickel

SUDBURY, ONTARIO--(Marketwire - Feb. 21, 2008) - Rockcliff Resources Inc. ("Rockcliff")(TSX VENTURE:RCR)(Tier 1) is pleased to announce that it has signed an option and joint venture agreement to earn a 70% interest in the Tower VMS Property from Pure Nickel Inc. ("Pure Nickel") (TSX:NIC). The property is located within the southern extension of the prolific Thompson Nickel Belt, Manitoba and is strategically located approximately 45 kilometres from the Company's 1600 km2 Snow Lake VMS Project which is located in the Flin Flon Greenstone Belt. The property is highly prospective for nickel mineralization and also hosts the Tower VMS Zone, a multi-zoned system rich in copper, zinc, gold and silver. The zone was tested and discovered in 2000 by eight drill holes. To date, the zone has a minimum strike length of 600 metres, a vertical depth of 400 metres and is open in all directions. Down hole geophysics has identified the Tower Zone as an extensive sheet of sulphides that continues to a depth of at least 700 metres vertical. It also identified several strong off-hole conductors worthy of follow-up drilling.

Rockcliff's 2008 exploration plans are to initiate a program of diamond drilling and geophysics to determine the size of the Tower VMS Zone and to determine the potential of the off-hole conductors proximal to the Tower Zone.

Highlights of the historical drill holes on the property are listed below.

To earn a 70% interest, 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; $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. Pure Nickel will be allowed to acquire 1.25 million warrants of Rockcliff at $1.50 per share for a period of two years. An underlying 2% NSR is controlled by Xstrata Nickel on the property of which half can be purchased for $1,000,000. In the first year of the option, Rockcliff must pay $30,000 in cash to Pure Nickel and drill a minimum of 2,000 metres.

Ken Lapierre, President and CEO of Rockcliff commented, "We are delighted and honoured that Pure Nickel has given us the opportunity to advance the Tower VMS Property. The Tower VMS Zone is a very large, pervasive, underexplored target that is open in all directions and was only ever tested by eight drill holes. We will aggressively drill this target in 2008 and feel that the potential to identify a deposit rich in copper, zinc, gold and silver is excellent."
