Rockland Retty Lake Cu-Ni-PGE Drilling Complete

VANCOUVER, BRITISH COLUMBIA--(Marketwire - June 22, 2011) - Rockland Minerals Corp. (TSX VENTURE:RL) (the "Company") has completed its 1,500 meter diamond drilling program on the Retty Lake Cu-Ni-Pt-Pd Property located near Schefferville, Quebec. A total of 10 holes were drilled to explore for zones of disseminated and massive sulfide within the targeted middle peridotite sill in the NW Retty Lake area. The core is being shipped off site to a core processing facility to be saw cut and sampled.

Initial logging of the core has revealed widespread disseminated sulfide mineralization with visible chalcopyrite (copper mineral) within the lower portion of the middle peridotite sill. In several instances, favourable "net-texture" sulfides were observed to be crystallized within cumulate-texture peridotite. Two drill holes found an unexpected rock type in place of the middle peridotite horizon. Instead of the ultramafic peridotite, there was a melanocratic gabbro, which indicates assimilation of the wall rock by the peridotite intrusion. This typically happens adjacent to feeder dykes, and suggests they may be nearby, although they have never been described at Retty Lake. Mineralization was also drilled in the upper sill, in addition to the widespread disseminated mineralization found in the middle sill. This confirms the presence of "stacked" mineralization at Retty Lake.

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: "We see highly encouraging disseminated sulfide textures in hand samples of the drill core from the Retty Lake Project, and we're only in the beginning stages of unlocking the copper-nickel-platinum-palladium potential of this district. Because this is the first drill core to come from this area since the 1950's, we plan on doing a careful, thorough job of sawing, splitting and sampling the core."

Photographs of Retty Lake drill core textures and a brief geological write-up have been posted on Rockland's website at

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.
