Rockcliff Resources Inc.: Final Shihan Drill Results Completed

SUDBURY, ONTARIO--(Marketwire - June 7, 2007) - Rockcliff Resources Inc. (TSX VENTURE:RCR) is pleased to announce that the final drill results from its first phase drill program have been received on its 100% owned Shihan VMS Project. The final results were from additional mineralized areas in hangingwall and footwall rocks located proximal to the Zinc Zone. The Zinc Zone remains the Company's main focus at the Shihan VMS Project. It is a single lens of semi-massive to massive sulphides with a strike length of at least 150 metres and has been drill tested to 150 metres vertical depth. The zone remains open to depth. Exploration plans for 2007 include a second phase of diamond drilling at the Zinc Zone and on numerous untested VMS geophysical targets throughout the project area.

The gold and silver results were intersected in the hangingwall and footwall rocks proximal to the main Zinc Zone. The assay results are tabulated below including:

- 4.50 metres grading 1.11 opt silver and 0.06 opt gold

- 2.30 metres grading 22.13 opt silver and 0.04 opt gold

- 1.00 metres grading 22.31 opt silver and 0.04 opt gold

- 3.35 metres grading 10.70 opt silver and 0.005 opt gold

- 0.60 metres grading 16.51 opt silver and 0.03 opt gold

- 0.50 metres grading 0.53 opt silver and 0.21 opt gold

- 1.15 metres grading 0.35 opt silver and 0.14 opt gold

Highlights of the gold and silver results from Rockcliff's first phase drill program are tabulated below. Previously reported drill results from the main Zinc Zone can be viewed on the company website at Drill lengths reported below are drill intersected core lengths and do not represent true widths.

Thirty (30) drill holes totaling 2,984.5 metres were completed in Phase 1. All gold and silver zones are associated with strongly altered felsic rocks and /or shear zones cross cutting the felsic rocks. The main Zinc Zone is interpreted as a single lens of semi-massive to massive sulphides located along a 2 km long favorable felsic horizon. The zone has a surface strike length of 150 metres and has been drill tested to a maximum vertical depth of approximately 150 metres. The zone remains open at depth.


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 laboratory 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 250g pulp is then prepared for assaying. A 10g 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.
