Attention Business Editors:

Wallbridge and Champion Bear enter into Option and Joint Venture Agreement in respect of Champion Bear's Parkin Property

     TORONTO and CALGARY, April 28 /CNW/ - Wallbridge Mining Company Limited
(TSX: WM, FWB: WC7) and Champion Bear Resources Ltd. (TSXV: CBA) are pleased
to announce that they have entered into an option and joint venture agreement
in respect of Champion Bear's Parkin Property, which encompasses approximately
1,200 hectares and covers 6.5 kilometres of strike length along the Parkin
Offset dyke. Under the terms of the agreement, Wallbridge has the right to
acquire a 50% interest in the property by making a $100,000 cash payment to
Champion Bear, issuing Champion Bear 263,158 common shares of Wallbridge and
incurring exploration expenditures on the property in the amount of $2,000,000
on or before April 24, 2010. If Wallbridge exercises its option, a joint
venture will be formed between Wallbridge and Champion Bear whereby each will
hold a 50% interest in the property. Initially, Wallbridge will be the
operator of the joint venture. Wallbridge may then increase its interest in
the property to 75% by completing a definitive feasibility study on a deposit
which is in whole or in part on the property and funding Champion Bear's
portion of development expenditures as a loan against Champion Bear's portion
of the proceeds of production.
     After earning pursuant to the agreement with Champion Bear, Wallbridge
will control a total of 9.4 kilometres along the dyke. This is the first time
that this package of claims has been held as a single unit and will enable a
comprehensive exploration program to be carried out. This is particularly
vital for the purpose of carrying out deeper penetrating geophysical surveys
between drill holes. The total property encompasses 2,150 hectares covering
9.4 kilometres of strike length of the dyke and includes:
     -  Wallbridge's Parkin Property (98.5% Wallbridge, 1.5% Xstrata Nickel),
        which hosts the Parkin Resource (43-101 Indicated Resources of
        290,928 tons @ 0.70% Cu, 0.65% Ni, 0.03% Co, 0.62 g/t Pt,
        0.80 g/t Pd, 0.23 g/t Au and 6.3 g/t Ag; resource calculated in 2002
        by A. Soever of Watts, Griffis and McOuat)
     -  Wallbridge's 100% owned Milnet Property, which hosts the past
        producing Milnet Mine (Produced 157,130 tons @ 1.54% Ni, 1.49% Cu,
        2.25 g/t Pt, 2.98 g/t and 0.33 g/t Au)
     -  Wallbridge's Champion Bear JV Property, which hosts the Brady Showing
        and several other targets on the Northern Block.
     Commenting on the agreement with Champion Bear, Alar Soever, President of
Wallbridge stated, "Offset dykes are very attractive exploration targets in
Sudbury as demonstrated by recently announced mine development projects at
Totten and Copper Cliff. This acquisition will allow the exploration of a
large mineralized section of the Parkin Offset to depth".
     "The opportunity to partner with Wallbridge on this highly prospective
property is a very positive milestone for Champion Bear", commented Richard
Kantor, Chairman and President of Champion Bear.
