Wallbridge Mining Extends Record Date for Special Warrant Dividend and
Spin-out of BC Properties into New Company, Miocene Metals Limited

TORONTO, April 19 /CNW/ - Wallbridge Mining Company Limited ("Wallbridge" or the "Company") (TSX: WM) today announced that the Company has extended the Record Date of its previously announced Special Warrant Dividend from April 23, 2010 to the close of business April 30, 2010 in order to give Wallbridge investors more time to ensure that they are registered shareholders.

This one week extension will ensure that all holders of existing warrants who wish to exercise have sufficient time to complete their exercise before the record date.

Wallbridge proposes to distribute to its shareholders a dividend consisting of special warrants exchangeable into common shares of Miocene Metals Limited ("Miocene Metals").

Miocene Metals is a new company created to acquire all of Wallbridge's British Columbia porphyry copper-gold-molybdenum properties. The transaction is modeled after Wallbridge's successful spin-out of its Minnesota properties into Duluth Metals Limited in 2005. That transaction, which saw Wallbridge shareholders and Wallbridge receive 21.8 million shares of Duluth Metals Limited, hasgenerated in excess of $40 million dollars of value for Wallbridge and Wallbridge shareholders.

As a stand alone entity Miocene Metals will more easily be able to finance advancement of these properties and will present to our shareholders a direct investment in an entire belt of Miocene-age intrusions with incredible potential, which has seen relatively little or no systematic exploration."

Under the terms of the plan, shareholders of Wallbridge will receive a dividend-in-kind of one special warrant of Miocene Metals for every 6 common shares of Wallbridge held as of the close of business April 30, 2010. Following this transaction, Miocene Metals will acquire from Wallbridge all of its BC properties in exchange for Miocene Metals common shares.

Miocene Metals will then complete a liquidity event which will be either (i) a significant financing of not less than $3,000,000 and the listing of the common shares of Miocene Metals on a Canadian or US stock exchange or (ii) a "reverse take-over" with a company listed on a Canadian or US stock exchange or (iii) the completion by Miocene Metals of an IPO and the listing of its shares on a Canadian or US stock exchange.

In the event that Miocene Metals does not complete one of the liquidity events by October 31, 2011,the special warrants will expire and Miocene Metals will continue to be a subsidiary of Wallbridge.

Immediate plans for Miocene Metals will be to complete a private placement financing, a joint venture with Wallbridge which will see Wallbridge fund an initial exploration program on the properties using its existing BC Flow Through funding, and to then to complete one of the liquidity events together with a further financing, which will allow for an aggressive exploration program on the properties.

Following this transaction, Miocene Metals will hold seven properties covering 1322.01 hectares of ground that is highly prospective for porphyry copper, gold and molybdenum mineralization in southwestern BC. The properties, including Rogers Creek, Mount Barr, Sunshine, Custer Ridge, Shulaps, Whitecross and MacKenzie (see Wallbridge BC Properties Showing Cascade Magmatic Arc on Wallbridge website at www.wallbridgemining.com), were staked or acquired through option agreements and cover Miocene-aged granodioritic to quartz-monzonitic felsic intrusions. These intrusions are part of the Cascade Magmatic Arc, which is geologically similar to the Miocene-aged Chilean porphyry belt, which hosts giant deposits such as Chuquicamata, El Teniente and Escondida.The seven properties range from grassroots stage, with known mineral showings and anomalous stream sediment and grab sample results, to properties that are almost drill-ready and have returned economic chip and grab sample values and drill intersections over widths of 10's of metres.

The summer 2010 program will be tailored to determine whether individual properties will advance to the next stage of exploration and will include first and second stage drilling as appropriate. It is anticipated that field work will commence by early May after consultation with local First Nations and other stake holders.

The Qualified Person responsible for the technical content of this press release is Bruce Jago, PhD. P.Geo, Vice-President, Exploration of Wallbridge Mining Company Limited.
