Rockcliff Continues to Hit High Grade Copper-Gold at Rail Zone - 3.62m Grading 5.05% Copper, 1.76g/t Gold, 2.77% Zinc and 19.4 g/t Silver - Second Drill Rig to be Added to Snow Lake Project

	    Trading Symbol RCR: TSXV

	    TORONTO, Feb. 16 /CNW/ - Rockcliff Resources Inc. (RCR: TSXV) is pleased
to announce that drilling on the Rail Zone continues to intersect high grade
copper-gold mineralization. The Rail property is part of Rockcliff's Snow Lake
Project located in central Manitoba. Hole RL10-50 intersected 3.62m of massive
sulphides grading 5.05% copper, 1.76g/t gold, 2.77% zinc and 19.4g/t silver
including 1.52m grading 8.01% copper, 2.45g/t gold, 2.61% zinc and 31.2g/t
silver. The hole was drilled in an area 30m north of the recent high grade
intersections (see release dated November 10, 2009) which included 4.74m
grading 9.02% copper, 3.46g/t gold, 1.62% zinc and 36.5g/t silver. Drilling
has now increased the Rail Zone to approximately 715m 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 is continuing on the Rail Zone and results will be reported to
the public when available.
	    Highlights from previous holes (RL07-01 to RL09-46) and additional maps
completed by Rockcliff on the Rail Zone can be viewed on the Company's website
at www.rockcliffresources.com. Highlights from the recent drill holes RL10-47
to RL10-50 are tabulated below including:

	    <<
	    -   0.46m grading 11.65% copper, 5.01g/t gold, 1.87% zinc and 49.7g/t
	        silver (RL10-47);

	    -   4.42m grading 1.46% copper, 0.28g/t gold, 1.32% zinc and 6.4g/t
	        silver including
	        1.34m grading 3.37% copper, 0.55g/t gold, 2.32% zinc and 13.5g/t
	        silver (RL10-48);

	    -   2.91m grading 1.97% copper, 2.91g/t gold, 1.22% zinc and 11.7g/t
	        silver including
	        1.01m grading 3.63% copper, 6.04g/t gold, 2.62% zinc and 18.7g/t
	        silver (RL10-49);

	    -   3.62m grading 5.05% copper, 1.76g/t gold, 2.77% zinc and 19.4g/t
	        silver including
	        2.10m grading 7.35% copper, 2.79g/t gold, 2.57% zinc and 28.6g/t
	        silver including
	        1.52m grading 8.01% copper, 2.45g/t gold, 2.61% zinc and 31.2g/t
	        silver (RL10-50).

	    Ken Lapierre, President and CEO of Rockcliff commented, "Near surface
drilling continues to intersect high grade massive sulphides representing a
continuation of the Rail Zone towards the north. Rockcliff is completing a
DPEM geophysical survey in an untested area north of the present results which
will assist in identifying any extensions to the zone of massive sulphides.
One of the two drill rigs will be dedicated to the Rail Zone for the
foreseeable future".
	    The second drill rig will focus on targets including DPEM & BHPEM
anomalies (Reed), an untested borehole anomaly (Freebeth) and untested, buried
ZTEM targets (Tramping and/or Squall). Rockcliff's properties, within its Snow
Lake Project, are situated within the Flin Flon greenstone belt, one of the
most prolific and the largest Proterozoic VMS District in the world.
	    Significant assay results from drill holes RL10-47 to RL10-50 are
tabulated below along with drill hole information. The lengths reported are
drill intersected core lengths and do not represent true widths.

	    Holes 47 to 50 are the furthest north holes that have intersected the
Rail Zone and extend the zone by an additional 30m of strike. The Rail Zone in
this area continues to be hosted by a single, massive sulphide lens rich in
copper, gold, zinc and silver and remains open along strike (715m) and at
depth (450m). An extension of the surface grid north of the high grade results
and a DPEM geophysical survey has been completed. Preliminary DPEM results
will be reported to the public when available.
	    Rockcliff has the exclusive right to earn a 100% interest in the Rail
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 Rail Property, HBED will receive a 2% Net Smelter Return
Royalty. If Rockcliff earns a 100% interest in the Rail Property, HBED then
has the right to acquire up to a 65% interest in the Rail Property. Please

	    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.
