Rockland Drills "Net-Texture" Sulfides in Ultramafic Rocks at Retty Lake Cu-Ni-PGE, Quebec

Marketwired
Rockland Minerals Corp. (TSX VENTURE: RL) (the "Company") has
intersected several zones of disseminated sulfides within the
targeted middle peridotite sill being drilled on the Retty Lake
Cu-Ni-Pt-Pd Property. In diamond drill hole number 849-05, drilled
near the "Lac Retty Ouest" showing, Rockland geologists have
observed very encouraging "net-textured" disseminated pyrrhotite
and visible chalcopyrite (copper mineral) within a 14-meter basal
zone of cumulate-texture ultramafic peridotite. Rockland is
currently half way through a planned 1,500 meter program, which
commenced on May 15th, 2011. After all drilling is complete,
assaying of the mineralized core will begin.
Hole 849-03 encountered 60 meters of disseminated pyrrhotite
with visible chalcopyrite -- in coarse cumulate- textured
peridotite -- at the Lost Lake showing. All of the drilling so far
has intersected zones of layered massive sulfide and cross-cutting
sulfide, within black shales. These metamorphosed sediments at
Retty Lake are intruded by mafic gabbros and ultramafic
peridotites, in a setting very similar to the southern Raglan
Cu-Ni-PGE mineralized belt in Quebec's Ungava region to the
north.
Upon completion of the drill program Rockland plans to transport
the Retty core to the IOS Services Geoscientifiques Inc. processing
facility where Rockland's geotechs will split and select
mineralized segments for assaying. Assay results will be made
available as completed.
George F. Sanders, P.Geo, a director of the Company, and
Qualified Person under National Instrument 43-101 responsible for
the technical content of this news release, states: "Our Retty Lake
drilling program is progressing very well. The 'net textured'
disseminated sulfides within the lower portion of the middle
peridotite sill are guides to discovery of more massive sulfide
lenses, similar to the adjacent Blue Lake Cu-Ni-PGE cluster. We
have chosen to transport the drill core offsite for more precise
logging, sawing and sampling. This is the first drilling in this
area since the 1960's, and Rockland intends to process it
thoroughly, to unlock the Cu-Ni-PGE potential of these deposits.
Sample shipments and assaying will be expedited, and results will
be released as soon as possible."
The Retty Lake property is on-trend with four adjacent
copper-nickel-platinum group metal (PGM) lenses known as the "Blue
Lake Deposits" -- originally outlined by Hollinger North Shore
Exploration (Iron Ore Company of Canada) in the 1950's. Evidently,
the Blue Lake Cu-Ni-Pt-Pd deposits were formed at or near the basal
zone of the ("Middle") ultramafic peridotite, where the sill
intrudes sulfur-rich metasediments. This favourable stratabound
horizon runs for some ten kilometers or more, throughout the
Rockland property, in a northwest-southeast trajectory. Rockland is
looking forward to discovery of additional base metal - precious
deposits within its Retty Lake property. Rockland is earning a 100%
interest in the property from E.D. Black, Geologist.
We seek Safe Harbor.
