Rockcliff Intersects VMS Mineralization at Snow Lake VMS Project

Second Phase 15,000m Drill Program Planned

SUDBURY, ONTARIO--(Marketwire - May 7, 2008) - Rockcliff Resources Inc. (TSX VENTURE:RCR) (Tier 1) is pleased to announce that a minimum drill program totalling 15,000m is planned on the Snow Lake VMS Project located in central Manitoba. Drilling will commence once winter breakup is complete. The Company's first phase drill program has now been completed in which 38 drill holes totalling 8,300m tested VMS (copper, zinc, gold and silver) mineralization on three properties at the Snow Lake VMS Project. Twenty-seven holes were completed at the Rail Property, seven holes at the Kof Property and four holes at the Sylvia Property. A total of 33 drill holes intersected significant VMS mineralization. All VMS zones intersected in the drilling are open along strike and at depth and are worthy of additional drilling. Significant drill results of the Phase 1 drill program can be viewed on the Company's website at www.rockcliffresources.com. The project is located within the Flin Flon Greenstone Belt, one of the most prolific and the largest Paleoproterozoic VMS district in the world.

Highlights from the final holes of the Phase 1 program at the Kof Property (K08-03 to 07) and from the Sylvia Property (SY08-03) are tabulated below including:



Sylvia Property
---------------
- 2.21m grading 2.68% copper and 403 ppb gold.

Kof Property
------------
- 5.49m grading 1.59% copper, 0.07% zinc and 409ppb gold including
1.07m grading 3.41% copper, 0.09% zinc and 540ppb gold and

- 3.60m grading 1.66% copper, 0.04% zinc and 80ppb gold.


The lengths reported are drill intersected core lengths and do not represent true widths. VMS mineralization on both properties strike approximately north-south and dip to the east. All drill holes were drilled from east to west.

Rockcliff's second phase of drilling will initially focus on the Lon and Rail Properties and on identifying the source of several untested high priority targets identified from the recently completed airborne survey by Geotech Ltd of Aurora, Ontario. Rockcliff recently raised approximately $4.2 million for its 2008 exploration program at the Snow Lake VMS Project. Please refer to the news release dated May 1, 2008 for further details.

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

QA-QC STATEMENT

Peter Wood, P.Eng., P.Geo., VP Exploration of Rockcliff, a Qualified Person under the definition of National Instrument 43-101, is responsible for the technical information in this press release and is responsible for verification and quality assurance of Rockcliff's exploration data and analytical results. Samples of half core 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 bagged core 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. Assay results are also sent directly to Rockcliff's independent QC consultant who monitors the lab's performance on an ongoing basis and ensures the quality of the results.
