Matachewan Consolidated Mines, Limited Announces Sale of Mine Property to Northgate Minerals Corporation
May 20, 2011 (Marketwire Canada) --
TORONTO, ONTARIO --

Matachewan Consolidated Mines, Limited
("MCM") (TSX VENTURE:MCM.A) announces the sale effective May 12, 2011,
to Northgate Minerals Corporation ("Northgate") (TSX:NGX)(NYSE Amex:NXG)
of its former producing gold property located in
the Matachewan Gold Camp, 50 miles southeast of Timmins,
Ontario.
The property consists of 24 mining leases in Powell and Cairo
townships, Larder Lake Mining Division, Ontario, which prior
to the sale had been optioned to Northgate as the company
builds the Young-Davidson gold mine.

Terms of the sale include cash of $216,500, retention of
the royalty of ore mined and processed from the property,
and Northgate assuming liability for a note payable on
the property of $383,434.

The base royalty is $1.00 U.S. per ton of ore mined and
processed from the property. An additional royalty will be
paid when the price of gold exceeds $270 U.S. per ounce.
This will amount to 5% of the increase per ounce recovered
above the base rate of $270 U.S. per ounce.
The royalty relates to the current reserves of approximately
600,000 tonnes on the 24 Powell and Cairo mining leases,
subject to this agreement.

These tonnes form part of an open pit containing 6.2 million
tonnes of ore and will be mined once Young-Davidson
commences production in 2012.
In addition, underground exploration activity within these
mining leases will commence shortly as Northgate explores
outside of its current reserve envelope.

Northgate is currently building the Young-Davidson mine,
which is scheduled to commence production in late Q1 2012.

Young-Davidson is forecasting an initial 15-year mine-life and
is projecting average annual production of 180,000 ounces of
gold at a cash cost of $400 per ounce.

Matachewan is a Canadian publicly-traded junior resource company
that has oil and gas investments in Western Canada.
