today jointly announce that New Gold has formally commenced its
previously announced take-over bid (the “Offer”) to acquire all of the
outstanding common shares of Rainy River at a price of $3.83 per
share. The Offer represents a premium of 67% to the volume weighted
average price of Rainy River shares on the Toronto Stock Exchange for
the 20 trading days ended May 30, 2013, the last trading day prior to
announcement of New Gold’s intention to make the Offer.

Pursuant to the Offer, Rainy River shareholders will be entitled to
receive, at their option, either $3.83 in cash or 0.5 of a New Gold
share, in each case subject to pro ration, for each Rainy River share
they own. The maximum amount of cash payable by New Gold under the
Offer will be approximately $198 million and the maximum number of
shares issuable by New Gold will be approximately 25.8 million, based
on the number of Rainy River shares outstanding on May 30, 2013 on a
fully-diluted basis as such term is defined in the Offer. The Offer is
subject to customary conditions, including that a minimum of 66 2/3% of
the outstanding Rainy River shares are tendered to the Offer. The Offer
values the fully-diluted in-the-money share capital of Rainy River, net
of Rainy River’s current cash balance, at approximately $310 million.

The Offer is open for acceptance until 5:00 p.m. (Toronto time) on July
24, 2013, unless the Offer is extended or withdrawn.

The board of directors of Rainy River, on the unanimous recommendation
of its Special Committee, has unanimously approved New Gold’s
acquisition of Rainy River pursuant to the Offer and has unanimously
recommended that Rainy River shareholders tender their shares to the
Offer. The recommendation of the Rainy River board is supported by
