Rockland Minerals Corp. (The "Company" or "Rockland"), (TSX VENTURE:RL) reports
that a technical report interpreting the data from a helicopter-borne
Time-Domain Electromagnetic and Magnetic survey (TDEM) on its 100% optioned
Retty Lake Cu-Ni-PGE property near Schefferville, Quebec is now available for
download on the Company's website: www.rocklandminerals.ca.
The report by Geophysique Camille St-Hilaire Inc. provides new, high-resolution
geophysical data, which has helped the Company outline numerous exploration
targets: http://www.rocklandminerals.ca/Presentation.php.
The Retty Lake property is on-trend with four known adjacent
copper-nickel-platinum group metals (PGM) lenses known as the "Blue Lake
Deposits" originally outlined by Hollinger North Shore Exploration in the
1950's. The Blue Lake Cu-Ni-Pt-Pd deposits were formed at or near the basal zone
of a fertile ultramafic peridotite sill, where it was intruded above sulfur-rich
metasediments. This favourable horizon runs through the Rockland property in a
northwest trajectory. Quebec government and academic publications state specific
grades and tonnages (non 43-101 compliant) for 4 main massive sulfide lenses at
Blue Lake. In general, each of the 4 massive sulfide lens is reported to contain
about 1 Mt of mineralized material averaging approximately 0.5% Ni, slightly
less than 1% Cu, and just under 1 g/t combined Pt+Pd. While believed to be
accurate, these estimates were made too early to be in accordance with National
Instrument 43-101 standards and should not be relied upon by investors. Rockland
is looking to discover additional lenses on the Retty Lake property.
The NW Retty Lake area is the number one priority prospect area for Rockland.
Within the NW Retty Lake area three zones stand out in compilations of previous
work since the 1950's: namely, Lac Retty Ouest, Lost Lake and Nancy Lake South.
Select surface sampling compiled from the Quebec government literature and
published in Rockland's qualifying technical report (2010) includes the
following anomalous metal values in surface rock samples collected from
peridotite outcrops and boulders:

The complete historical compilation of interesting Cu-Ni-Pt-Pd values from Retty
Lake sampling with bibliography and maps can be found in the Retty Lake 43-101
Technical Report on the Company's website.
The Company is currently planning its next exploration on Retty Lake and will
release program details soon.
President, Rav Mlait, states: "The price of copper, platinum and palladium are
very strong which should bode well for Rockland as we continue to uncover the
mineral potential at Retty Lake."
The survey was flown in August 2010 by Geo Data Solutions, Inc. of Laval, Quebec
over the Rockland Retty Lake claims, consisting of a North block and a South
block, for a total of 1,767 line-kilometres. Rockland is earning a 100% interest
in the property from E.D. Black. The property consists of 210 mineral claims in
the Labrador Trough.
