08:51 EDT Thursday, March 22, 2007

SUDBURY, ONTARIO--(CCNMatthews - March 22, 2007) - Rockcliff Resources Inc. (TSX VENTURE:RCR) is pleased to announce that surface boreholes at the Zinc Zone continues to intersect massive sulphides rich in zinc and silver. Rockcliff's Zinc Zone is located within its 100% owned Shihan VMS Property located in central Ontario. Drilling continues to determine the overall dimensions of the Zinc Zone.

Highlights of drill intersections from the Zinc Zone are tabulated below, including:

- 4.25 metres grading 7.43% zinc and 3.76 opt silver including 1.8 metres grading 14.50% zinc and 3.65 opt silver

- 3.50 metres grading 6.01% zinc and 6.53 opt silver including 1.50 metres grading 13.01% zinc and 6.83 opt silver

- 5.15 metres grading 7.31% zinc and 2.95 opt silver including 2.10 metres grading 11.56% zinc and 4.05 opt silver

- 2.5 metres grading 17.63% zinc and 4.29 opt silver including 1.75 metres grading 23.73% zinc and 3.59 opt silver

To date, 22 boreholes have been completed with assay results returned from the first seven boreholes (RS07-01 to RS07-07). Results from boreholes RS07-01 and 02 were reported in Rockcliff's news release dated February 27, 2007. Drilling has identified the Zinc Zone across a strike length of 150 metres and to a maximum vertical depth of 110 metres. The Zinc Zone remains open along strike and to depth.

Highlights of significant Rockcliff borehole assay results are tabulated below. The lengths reported are drill intersected core lengths and do not represent true widths.

Additional assay results from completed boreholes (RS07-08 to 22) will be released to the public once the Company receives the results from the assay lab.

The Rockcliff boreholes being reported today are confirmatory in nature and are exploring the general vicinity where boreholes completed in 1980 by Westfield Minerals Ltd. outlined a near surface historical resource of 67,132 tonnes grading 12% zinc and 280 g/t silver. A 43-101 report on the Shihan property by CCIC Inc. dated November 14, 2006 concluded that the historical resource was not compliant with National Instrument 43-101and as such should not be relied upon. However, the historical estimate was determined to be relevant to the Company's interest in the property and was most likely reliable based on the information and methods used at the time. They recommended significant additional drilling of the Zinc Zone and along its potential strike and depth extensions to determine the scope of the mineralization.

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 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 Accurassay Laboratories in Thunder Bay, Ontario. Accurassay is a Canadian assay lab accredited by the Standard Council of Canada to ISO/IEC 17025 guidelines for precious metal and base metal analyses and meets all of the requirements outlined for NI 43-101.

Each bagged core sample is dried if necessary, crushed and pulverized to 90% minus 150 mesh and a 250-gram pulp is then prepared for assaying. A 10 g cut is taken from each pulp for base metal and ICP analyses and leached in a multi acid (total) digest and then analyzed for a variety of metals (including copper, lead, silver and zinc) by ICP-AES. Ore grade assays (greater than 5000ppm) are then determined by atomic absorption. Gold concentrations are determined by fire assay using a 1 assay-ton charge followed by an atomic absorption finish. Rockcliff inserted certified blanks and standards in the sample stream to ensure lab integrity.

Ken Lapierre P.Geo., of Rockcliff, a qualified person under the definition of National Instrument 43-101, has reviewed and approved the contents of this news release.
