Rockland Minerals Releases Technical Report on Retty Lake Airborne Survey

VANCOUVER, BRITISH COLUMBIA--(Marketwire - March 15, 2011) - 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 Géophysique 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. Québec 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 Québec 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, Québec 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.
