VANCOUVER, Sept. 19, 2011 /CNW/ - New Gold Inc. ("New Gold") (TSX:NGD)(NYSE AMEX:NGD) today announces an updated National Instrument 43-101 compliant mineral resource estimate for the Blackwater Project in central British Columbia.

• Indicated gold resource: 165 million tonnes at an average grade of 1.01 g/t containing 5.4 million ounces of gold
• Inferred gold resource: 39 million tonnes at an average grade of 0.94 g/t containing 1.2 million ounces of gold

The updated mineral resource estimate incorporates drill results from both the 100%-owned southern portion of the project and the 75%-owned northern portion, where Silver Quest Resources Ltd. owns the remaining 25%. The resource estimates by property are summarized in the table below:

New Gold's share of Indicated resources increased by 3.0 million ounces to 4.8 million ounces when compared to the initial March 2011 resource estimate for the deposit. This increase was a result of continued drilling which led to approximately 1.0 million ounces of Inferred resources from the March 2011 estimate being upgraded leaving New Gold's share of Inferred resources at 1.0 million ounces compared to 2.0 million ounces in March 2011. 

"We are thrilled to be able to provide this update on Blackwater which further supports the great potential we see for this asset," stated Randall Oliphant, Executive Chairman. "For our exploration team to have already added over 50% to our gold resources at Blackwater is an excellent start. We intend to aggressively progress this asset for the benefit of our shareholders."

The updated estimate incorporates drilling completed through July 2011. New Gold continues to actively drill the deposit which remains open in all directions and at depth. The table below summarizes the mineral resource estimate for the deposit at selected cut-off grades:

 "We are extremely pleased with the updated resource as we have added meaningfully to the gold resource both in size and quality in a short period of time," stated Mark Petersen, Vice President, Exploration. "While this is a great first step, we are equally excited about the continued potential of Blackwater both around and below the current resource as well as on the greater Blackwater property. We look forward to additional strong results through the remainder of 2011 and into the future."

The updated mineral resource estimate adds an additional 71 core holes (24,660 metres) to the initial March 2011 resource estimate, bringing the total number of core holes used for the estimate to 148 (49,223 metres). Grade estimation was carried out by the inverse distance cubed method using 5 metre downhole drill composites. Gold grades were capped prior to compositing at 11 g/t within a low grade outer grade shell domain and at 17 g/t within an inner higher grade domain based on a 0.5 g/t grade shell. All silver grades were capped at 50 g/t. Classified blocks were constrained by an optimized pit shell using a gold price of $1,200 per ounce. Block dimensions were 10 by 10 by 10 metres. Density values assigned to the principal lithologies are based on 7,705 bulk density measurements of drill core.

The resource estimate and other scientific and technical information contained in this news release were prepared by Mr. Ronald Simpson, P. Geo, President of Geosim Services Inc., an independent "Qualified Person" under National Instrument 43-101 Standards of Disclosure for Mineral Projects ("NI 43-101"). The NI 43-101 technical report in respect of the mineral resource estimate disclosed herein will be filed on SEDAR within 45 days of the date of this news release. Mark Petersen, New Gold Vice President, Exploration, Certified Professional Geologist and "Qualified Person" under NI 43-101 has reviewed and approved the contents of this news release.

New Gold continues to actively drill the Blackwater deposit and looks forward to providing further updates on the company's exploration efforts over the coming months.

Cautionary Note To U.S. Readers Concerning Estimates Of Measured, Indicated And Inferred Mineral Resources

Information concerning the properties and operations of New Gold 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 press 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 December 11, 2005. While the terms "Mineral Resource", "Measured Mineral Resource", "Indicated Mineral Resource" and "Inferred 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 press 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.
