Rockcliff Hits More High Grade Copper Mineralization at Snow Lake

8.01m Grading 3.11% Copper Including 2.75m Grading 5.16% Copper

Rail Zone Open in all Directions

Trading Symbol RCR: TSXV

TORONTO, Dec. 8 /CNW/ - Rockcliff Resources Inc. (RCR: TSXV) is pleased to announce that drilling on the Rail Zone has intersected additional high grade copper mineralization on its Snow Lake VMS Project located in central Manitoba. Hole RL09-45 intersected 8.01m of stringer sulphides grading 3.11% copper, 0.30g/t gold and 5.1g/t silver including 2.75m grading 5.16% copper, 0.59g/t gold and 8.0g/t silver. The hole was drilled in an area south of the historic Rail VMS Deposit where recent down hole geophysics on previously drilled copper rich holes detected a large untested conductor south of and on strike to the Rail Zone. Drilling has now increased the Rail Zone mineralization (copper, gold, zinc and silver) to approximately 700m of strike length and up to approximately 450m deep. The Rail Zone remains open in all directions and is hosted within juvenile arc rocks of the Snow Lake camp. All VMS mines within the camp are hosted in juvenile arc rocks of the Flin Flon greenstone belt. Drilling will continue on the Rail Zone early in the New Year.

Highlights from previous holes (RL07-01 to RL09-38) completed by Rockcliff on the Rail Zone at the Rail Property can be viewed on the Company's website at www.rockcliffresources.com. Highlights from the recent drill holes RL09-39 to RL09-46 are tabulated below including:

    
    -   1.48m grading 2.58% copper, 1.50g/t gold, 2.67% zinc and 10.5g/t
        silver (RL09-40);

    -   2.28m grading 3.37% copper, 0.79g/t gold, 1.31% zinc and 12.5g/t
        silver including 1.11m grading 6.12% copper, 1.78g/t gold, 2.09% zinc
        and 22.6g/t silver (RL09-41);

    -   4.05m grading 2.29% copper, 0.38g/t gold, 0.15% zinc and 5.1g/t
        silver including 1.83m grading 2.89% copper, 0.53g/t gold, 0.09% zinc
        and 6.2g/t silver (RL09-44);

    -   10.12m grading 2.61% copper, 0.51g/t gold, 0.08% zinc and 4.4g/t
        silver including 8.01m grading 3.11% copper, 0.30g/t gold, 0.08% zinc
        and 5.1g/t silver including 2.75m grading 5.16% copper, 0.59g/t gold,
        0.10% zinc and 8.0g/t silver (RL09-45).
    

Ken Lapierre, President and CEO of Rockcliff commented, "Drilling on the Rail Zone has consistently returned excellent copper and copper-gold results. Our goal at Rail is to determine the zone's extent and then complete a NI 43-101 resource estimate. With an additional four VMS deposits, a former gold producer and numerous untested VTEM and ZTEM airborne targets as part of our Company's Snow Lake Project, we remain very optimistic of realizing our ultimate goal of becoming mine finders in this camp".

To date, a total of 4062.5m in fourteen surface drill holes (RL09-33 to RL09-46) have been completed and reported in this drill phase on the Rail Property. The Rail Zone intersected in holes 33, 34, 35, 44, 45 and 46 was copper rich and drilled south of the historic Rail Deposit.

The Rail Zone intersected in drill holes 36, 37, 38, 39, 40, 41, 42, and 43 was copper-gold rich and drilled north of the historic Rail Deposit. The Rail Zone has been drilled to a present strike length of 685m and to depths of up to 450m and remains open in all directions. The zone consists of stringers and massive sulphide lenses of pyrite, pyrrhotite, chalcopyrite (copper-rich) and sphalerite (zinc-rich) hosted within a favourable 5km long trend of prospective juvenile arc rocks located on the property. An expansion of the surface grid north of the present drilling will begin shortly once ground conditions are frozen. This will allow additional geophysics and drilling to be completed in an untested area north of the Company's northern most holes which intersected mineralization up to 4.74m grading 9.02% copper, 3.46g/t gold, 1.62% zinc and 36.5g/t silver (RL09-37; please refer to press release dated November 10, 2009).

Drilling on the Rail Zone is planned to continue after the Christmas break in the New Year. Additional drilling in 2010 on the Snow Lake Project will include areas with VMS and gold potential and will be reported once drill targets are finalized.

Significant assay results from drill holes RL09-39 to RL09-46 are tabulated below along with drill hole information. The lengths reported are drill intersected core lengths and do not represent true widths.

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.
