New Gold Agrees to Acquire Rainy River Resources Growing Gold Reserves by Over 40 Percent per Share

• Asset located in great mining jurisdiction, near infrastructure

• Significant and immediate premium of 42% to current share price and 67% to 20-day volume weighted average share price
• Flexibility to elect form of consideration in either cash or highly liquid New Gold shares
• Opportunity to gain exposure to New Gold's current operating cash flow and attractive growth portfolio
• Access to New Gold's strong balance sheet and current and future operating cash flow to develop the Rainy River project
• Ability to partner with New Gold's experienced management and operating teams

On April 10, 2013, Rainy River announced the results of a Feasibility Study for the project, with 4.0 million ounces in Proven and Probable gold reserves and 6.2 million ounces in Measured and Indicated gold resources, inclusive of reserves. The Feasibility Study contemplates a 21,000 tonne per day processing rate from a combination of open pit, underground and stockpiled ore. The project has the potential to produce over 225,000 ounces of gold annually, at below industry average cash costs⁽¹⁾, for an initial mine life of 16 years. The Feasibility Study also highlights the potential to process higher grade ounces in the project's early years, while stockpiling lower grades for processing towards the end of the mine life. This should help drive higher production and lower costs at the beginning of the mine life, enhancing both cash flow and the overall economics of the project.

Rainy River's Board of Directors and management team have entered into lock-up agreements with New Gold agreeing to tender their shares, including shares issuable on the exercise of stock options, and support the transaction.

The Agreement between New Gold and Rainy River provides for, among other things, a non-solicitation covenant on the part of Rainy River subject to customary "fiduciary out" provisions, a right in favour of New Gold to match any superior proposal and a payment to New Gold of a termination fee of approximately $14 million in certain circumstances, including if Rainy River accepts a superior proposal.

The Offer is expected to commence during the week of June 10, 2013 upon the mailing of New Gold's takeover bid circular and related documents, which will include full details of the Offer. Rainy River's directors' circular, which will set out the unanimous recommendation of the board of Rainy River that shareholders accept the Offer, will also be mailed. The Offer will be open for acceptance for a period of not less than 35 days from the date of mailing of the takeover bid circular and will be conditional upon, among other things, there being deposited under the Offer, and not withdrawn at the expiry time, shares representing not less than 66 2/3% of the Rainy River shares on a fully diluted basis. In addition, the Offer will be subject to certain customary conditions, including receipt of relevant regulatory approvals and the absence of a material adverse change with respect to Rainy River.

New Gold's financial advisor is RBC Capital Markets and its legal advisors are Cassels Brock & Blackwell LLP in Canada and Paul, Weiss, Rifkind, Wharton & Garrison LLP in the United States.

Rainy River's financial advisor is BMO Capital Markets and its legal advisors are Bull, Housser & Tupper LLP and Davies Ward Phillips & Vineberg LLP. CIBC World Markets provided a fairness opinion to Rainy River's Special Committee.

Cautionary Note to U.S. Readers Concerning Estimates of Measured, Indicated and Inferred Mineral Resources

Information concerning the properties and operations discussed in this news release has been prepared in accordance with Canadian standards under applicable Canadian securities laws, and may not be comparable to similar information for United States companies. The terms "Mineral Resource", "Measured Mineral Resource", "Indicated Mineral Resource" and "Inferred Mineral Resource" used in this news release are Canadian mining terms as defined in accordance with NI 43-101 under guidelines set out in the Canadian Institute of Mining, Metallurgy and Petroleum ("CIM") Standards on Mineral Resources and Mineral Reserves adopted by the CIM Council on November 27, 2010. While the terms "Mineral Resource", "Measured Mineral Resource" and "Indicated Mineral Resource" are recognized and required by Canadian regulations, they are not defined terms under standards of the United States Securities and Exchange Commission. Under United States standards, mineralization may not be classified as a "reserve" unless the determination has been made that the mineralization could be economically and legally produced or extracted at the time the reserve calculation is made. As such, certain information contained in this news release concerning descriptions of mineralization and resources under Canadian standards is not comparable to similar information made public by United States companies subject to the reporting and disclosure requirements of the United States Securities and Exchange Commission. An "Inferred Mineral Resource" has a great amount of uncertainty as to its existence and as to its economic and legal feasibility. It cannot be assumed that all or any part of an "Inferred Mineral Resource" will ever be upgraded to a higher category. Under Canadian rules, estimates of Inferred Mineral Resources may not form the basis of feasibility or other economic studies. Readers are cautioned not to assume that all or any part of Measured or Indicated Resources will ever be converted into Mineral Reserves. Readers are also cautioned not to assume that all or any part of an "Inferred Mineral Resource" exists, or is economically or legally mineable. In addition, the definitions of "Proven Mineral Reserves" and "Probable Mineral Reserves" under CIM standards differ in certain respects from the standards of the United States Securities and Exchange Commission.

Rainy River Mineral Reserves

Open pit mineral reserves have been estimated using a cut-off grade of 0.30 g/t gold-equivalent, and underground reserves have been estimated using a cut-off grade of 3.5 g/t gold-equivalent. Open pit reserves have been estimated using a dilution of 9.7% at 0.22 g/t Au and 1.31 g/t Ag, and underground reserves have been estimated using a CAF dilution of 9% at 0.61 g/t Au and 4.16 g/t Ag and LH dilution of 10% at 1.56 g/t Au and 1.28 g/t Ag. Open Pit Reserves have been estimated using a mine recovery of 95%, and Underground reserves have been estimated using a mine recovery of 95%. Additional details regarding the Mineral Reserve estimate and related Feasibility Study are provided in the May 23, 2013 NI 43-101 Technical Report available on SEDAR.


Rainy River Mineral Resources

Mineral resources are not mineral reserves and do not have demonstrated economic viability. Mineral resources are reported relative to conceptual open pit shells. On average, the conceptual open pit extends to an elevation of 500 metres below surface. Material above this elevation offers reasonable prospects for economic extraction from an open pit because drilling results suggest that the zone of gold mineralization is broader than currently modeled and that new drilling information should positively impact future mineral resources. Material below this elevation is potentially mineable by underground mining methods. Mineral resources that are potentially mineable by open pit methods are reported at a cut-off grade of 0.35 g/t gold; underground mineral resources are reported at a cut-off grade of 2.5 g/t gold. All mineral resources are based on a gold price of US$1,100 per ounce, a silver price of US$22.50 per ounce, a foreign exchange rate of 1.10 Canadian dollars to 1.0 US dollar. Metallurgical recoveries include 88% for gold in open pit resources and 90% for gold in underground resources, with a silver recovery of 75% in both cases.

All figures are rounded to reflect the relative accuracy of the estimate. Figures may not add due to rounding. Additional details on the Mineral Resource estimate are provided in the Rainy River news release dated October 10, 2012.  Mineral Resources were estimated by SRK Consulting (Canada) Inc. ("SRK") and are reported in accordance with Canadian Securities Administrators National Instrument 43-101.


(1) TOTAL CASH COSTS

"Total cash costs" per ounce figures are calculated in accordance with a standard developed by The Gold Institute, which was a worldwide association of suppliers of gold and gold products and included leading North American gold producers. The Gold Institute ceased operations in 2002, but the standard is widely accepted as the standard of reporting cash costs of production in North America. Adoption of the standard is voluntary and the cost measures presented may not be comparable to other similarly titled measures of other companies. Each of New Gold and Rainy River reports total cash costs on a sales basis. Total cash costs include mine site operating costs such as mining, processing, administration, royalties and production taxes, but are exclusive of amortization, reclamation, capital and exploration costs. Total cash costs are reduced by any by-product revenue and is then divided by ounces sold to arrive at the total by-product cash cost of sales. The measure, along with sales, is considered to be a key indicator of a company's ability to generate operating earnings and cash flow from its mining operations. This data is furnished to provide additional information and is a non-IFRS measure. Total cash costs presented do not have a standardized meaning prescribed by IFRS and may not be comparable to similar measures presented by other mining companies. It should not be considered in isolation as a substitute for measures of performance prepared in accordance with IFRS and is not necessarily indicative of operating costs presented under IFRS. A reconciliation is provided in the respective MD&A and accompanying the quarterly financial statements of each of Rainy River and New Gold.
