Manicouagan Minerals Confirms and Expands Copper-Silver Mineralization at Lac Maugue

TORONTO, ONTARIO--(CCNMatthews - Sept. 11, 2007) -

Attention Business Editors:

Manicouagan Minerals Inc. (TSX VENTURE:MAM)announced today encouraging assay results from field-work completed in July and August of 2006 on the Lac Maugue Copper/Silver property in the Dunphy-Romanet Lakes area of the central Labrador Trough region of central Quebec. The property is located approximately 160 kilometres northwest of the
all services town of Schefferville, Quebec.

Recent work completed by MPH Consulting Limited on behalf of Manicouagan Minerals has confirmed the existence of significant copper-silver mineralization in bedrock trench 93-5. (Trench 93-5 was originally sampled in 1993-94, for Outokumpu Mines Ltd.) Field-work completed this summer has also outlined several new copper-silver and lead-zinc occurrences and extensions to known zones of mineralization.

Detailed airborne geophysical (AEM, magnetics) surveys by Fugro Airborne Services in August 2006 indicate that the mineralization in the area of the Lac Maugue showings has an associated discernable magnetic signature, which has an overall strike length in excess of three kilometres.

New channel samples of dolostone/siltstone mineralized with chalcopyrite, bornite and malachite from bedrock trench 2006-1 located 97 metres northwest of trench 93-5 along the Lac Maugue copper-silver zone averaged 132 g/t
silver, 0.86% copper over 4.85 metres. Included in this channel sample was a 1.0 metre section that assayed 237 g/t silver, 1.50% copper.

The field crew discovered numerous additional copper-mineralized boulders in the boulder field 800 metres northwest of trench 93-5. The bedrock source of this material is under drift cover but is postulated to be very close to the boulder field.

The probable extension to the southeast of the Lac Maugue mineralized stratigraphy was discovered on the east shore of Lac Maugue, some two kilometres south of trench 93-5. One sample taken from this zone contains anomalous copper, lead and zinc concentrations and further sampling/prospecting will be conducted in this area.

Lead-zinc mineralization was also discovered in dolomitic bedrock at the south end of Lac Maugue. Selected grab samples from a 0.5 to 1.5 metre dolostone layer with galena, sphalerite, quartz veining and breccia matrix
averaged 53 g/t silver, 5.91% lead and 3.58% zinc. Approximately 1.2 kilometres northwest of these samples, additional dolostone boulders with visible lead-zinc mineralization were discovered by the field crew along the
lakeshore. A selected grab sample from a 1.5 x 1.0 x 1.0 metre subangular dolostone boulder with quartz veining and sphalerite-galena assayed 90 g/t silver, 10.65% lead, 7.53% zinc.

As noted above, the recently completed detailed airborne geophysical (AEM, magnetics) surveys by Fugro Airborne Services indicate that the mineralization in the area of the Lac Maugue showings has an associated discernable magnetic signature which has an overall strike length in excess of three kilometres. There are also areas of enhanced conductivity offset from and adjacent to the zone of increased magnetic susceptibility. This may reflect an oxidation-reduction boundary that may control mineral deposition, a common feature of sedimentary hosted copper mineralization and as such it constitutes a focus for future exploration at Lac Maugue.

A sketch showing the location of the project and related mining claims, the regional geology as well as detailed geology and sampling of the Lac Maugue showing area can be found with the copy of this press release posted on
the Company's website at Details of sample results shown on the sketch are also included in the attached table.

Fieldwork on the project is ongoing. The AEM survey, which initially focused on Lac Maugue, was completed in late August and preliminary field data are being compiled and processed to identify prospective geophysical targets.
A number of high priority geophysical targets proximal to known showings or mineralized boulders have already been identified and helicopter supported ground crews are currently in the field completing prospecting and sampling of
these targets initially in order to select those targets that will require further work. It is anticipated that some targets will require detailed ground geophysics as a prelude to drilling in 2007.

Joseph Baylis, President and Chief Executive Officer of Manicouagan Minerals noted that the "Lac Maugue project has progressed rapidly since it was acquired in July of this year and these initial results are certainly
encouraging." He further noted that the Company "is determined to aggressively develop its portfolio of exploration projects and will move quickly to advance projects like Lac Maugue to the drill stage."


The Lac Maugue Copper/Silver property consists of 88 claims acquired from the Labrador Silver Syndicate ("LSS"). Manicouagan Minerals can acquire a 100% interest in the property subject to a 3 percent Net Smelter Return (NSR)
royalty of which 2/3 of the 3% NSR may be bought out for $2,000,000. The NSR applies to the Lac Maugue property as well as any other claims acquired by Manicouagan Minerals or the LSS within ten kilometres of the outer boundary of the existing 88 claims forming the Lac Maugue property. (See MAM Press Releases dated June 27 and July 31, 2006.)

A portion of the property secures an area where prospecting and trenching on behalf of Outokumpu Mines Ltd. in 1993-94 over a largely overburden covered area with underlying bedrock consisting of magnetite rich argillite, dolomite and sandy dolomite encountered significant copper-silver mineralization in outcrop and boulders. One 3.19-metre section in bedrock trench 93-5, sampled in 1993, assayed 0.61% copper and 135 g/t silver including a 0.5 metre section which assayed 1.26% copper and 267 g/t silver. Prospecting work some 800 metres northwest of, and along trend with, the above area in the early 1990's on behalf of Outokumpu Mines Ltd. reportedly discovered mineralized boulders that assayed up to 2.32% copper and 82.5 g/t silver. These results pre-date 43-101 requirements. The bedrock source of this material has not yet been discovered.

Occurrences of copper, silver, lead, zinc, gold and other metals are widespread throughout the central Labrador Trough and the Dunphy-Romanet Lake region has known metal associations (uranium, copper, gold) and a geological
environment which is indicative of potential for iron oxide copper-gold type deposits in addition to the sediment-hosted copper-silver mineralization found at Lac Maugue.

In view of the geological environment and the potential for large tonnage sedimentary-hosted deposits, Manicouagan Minerals earlier this year acquired an additional 470 claims covering approximately 22,560 hectares by way of map
designation to secure selected areas of geological interest which are considered to have potential to host sedimentary hosted copper-silver deposits similar to the occurrences at Lac Maugue. The majority of these claims lie within the ten kilometre Area of Interest created by the agreement with the LSS. Following the registration and acceptance of these claims by the Province of Quebec, Manicouagan Minerals will grant the LSS a 1% NSR royalty in the portion of the 470 map designated claims falling outside of the ten kilometre area of interest.

More recently, Manicouagan Minerals has map designated an additional 46 claims. Sixteen of these claims are shown on the sketch that can be found with the copy of this press release posted on the Company's website. The remaining thirty claims have been map designated to protect the presumed eastward extension of the Lac Maugue stratigraphy.

Exploration programs at Lac Maugue are being carried out under the supervision of Rod Thomas, Vice President - Exploration of the Company. Mr. Thomas, a professional geologist, has reviewed and verified the technical content of this press release on behalf of Manicouagan Minerals and qualifies under the definition of "Qualified Person" set out in National Instrument 43-101.
