VANCOUVER, BRITISH COLUMBIA--(Marketwired - April 23, 2013) - Rockland Minerals Corp. (TSX VENTURE:RL) (the "Company") is pleased to announce receipt of a new Technical Report which outlines significant Cu-Ni-PGM discovery potential on the Blue Lake Project, Labrador Trough, Québec. The independent report details the 2012 Blue Lake drill program, provides new historical context, and presents several positive conclusions on the expansion of Cu-Ni-PGM mineralization at Blue Lake and surrounding areas. A web version of the Blue Lake Technical Report can be downloaded from the company's website at rocklandminerals.ca.
The new Technical Report (IOS Services Géoscientifiques Inc. 2013), states that mineralized intervals tested in the "middle sill" ultramafic unit during the drilling campaign confirmed the location and continuity of the massive sulphide ore intersections described in previous work at Blue Lake from the 1950's to the 1980's. Rockland's 2012 drilling replicated the significant assay values for copper, nickel, platinum and palladium in the massive sulphide bands and lenses used to calculate the Blue Lake historical (pre-National Instrument 43-101) resource in 1989. In several cases, careful core recovery increased thicknesses of known mineralized intervals. Broad intervals of disseminated sulphide mineralisation not systematically sampled during previous drilling campaigns were documented by Rockland Minerals, and these contribute significantly to the overall near-surface bulk potential at Blue Lake.
The report introduces a conservative, recovery-based, copper-equivalent value ("CuEq") for the Blue Lake massive sulphides to better help see the shapes of the Blue Lake mineralized bodies. Using this CuEq criteria, at 60% Ni recovery typical of these pyrrhotitic nickel ores, the non-43-101 Blue Lake 1989 historical massive sulphide resource is greater than 4 MT at a grade of greater than 2.2% CuEq. All the Blue Lake massive sulphides included in the historic resource contain approximately 0.2 g/t Pt and 0.8 g/t Pd, with richer grades in thin Pt-Pd-rich shear zones around the fringes of the massive sulphide lenses. These Pt-Pd rich zones were observed and tested in 1987, when a 350 meter underground bulk sample adit was driven into the Blue #1 massive sulfide lens. Elsewhere in the district, Rockland's claims cover two additional zones, within 4 kilometres on either side of Blue Lake, which hold excellent down-dip expansion potential. These zones, Starr Lake to the west, and Berry Lake to the east, both have historic massive sulphide drill intercepts greater than 1-metre thick with Blue Lake-style Cu-Ni-PGM values in excess of 2% CuEq, with the same tenor of Pt-Pd values.
George F. Sanders, P.Geo, Director and Qualified Person responsible for the technical content of this News Release, states: "Rockland found all the old drill locations in the field, and our 2012 drill results now verify the excellent quality of the historical Blue Lake resource data. Higher Pd values in the new CuEq equation drew the resource modeler to spot several holes at the edges of known sulfide bodies at Blue Lake #2-6, and Centre #2 zones. Results from these holes confirm potential to expand the Cu-Ni-PGM resources at Blue Lake."
