Rockcliff Hits Wide Mineralized Horizon with Multiple Zones of VMS Mineralization on the Kof Property at Snow Lake, Manitoba

SUDBURY, ONTARIO--(Marketwire - March 25, 2008) - Rockcliff Resources Inc. (TSX VENTURE:RCR)(Tier 1) is pleased to announce that initial drilling has intersected a wide mineralized horizon hosting multiple VMS zones rich in copper, gold and silver at the Kof Property on its Snow Lake VMS Project located in central Manitoba. Drilling intersected a 15.24m wide zone grading 1.84% copper, 0.30g/t gold and 7.6 g/t silver with additional higher grade zones of up to 1.52m grading 3.26% copper, 2.26g/t gold and 14.0g/t silver. The VMS mineralization has been intersected across a strike length of 150m and to a vertical depth of 200m and is open in all directions. The VMS mineralization is associated with juvenile arc rocks, the same type of rocks that hosts all of the mined VMS deposits in the Flin Flon and Snow Lake camps. The Snow Lake Project is located within the Flin Flon greenstone belt, one of the most prolific and the largest Paleoproterozoic VMS district in the world.

Seven surface drill holes totaling 1,651m have been completed on the Kof Property. Highlights from the first two holes are tabulated below including:



- 15.24m grading 1.84% copper, 0.30g/t gold and 7.6g/t silver including
4.58m grading 2.39% copper, 0.35g/t gold and 7.2g/t silver including
1.52m grading 2.83% copper, 0.28g/t gold and 7.9g/t silver; and
- 6.10m grading 1.49% copper, 0.91g/t gold and 7.8g/t silver including
1.52m grading 3.26% copper, 2.26g/t gold and 14.0g/t silver.


Significant assay results from drill holes K08-01 to K08-02 have been received from the analytical laboratory and are tabulated below along with drill hole information. The results from K08-03 to K08-07 will be reported once Rockcliff receives them from the laboratory. The lengths reported are drill intersected core lengths and do not represent true widths.

The Kof Property contains several wide zones of VMS mineralization consisting of stringers and massive sulphides lenses of pyrite, pyrrhotite and chalcopyrite. The multiple zones are associated with an extensive, underexplored, conductive horizon within a pervasive, highly altered, juvenile arc rock package. The zones remain open along strike and at depth and are within and proximal to the historical Kof Deposit. Additional drilling will be required to expand the historical limits of the Kof Deposit and to determine the extent of additional zones identified to date in Rockcliff's drilling.

Rockcliff has the exclusive right to earn a 100% interest in the Kof 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 Kof Property, HBED will receive a 2% Net Smelter Return Royalty. If Rockcliff earns a 100% interest in the Kof Property, HBED then has the right to acquire up to a 65% interest in the Kof Property.

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 news 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.
