3) Cerro San Pedro mineral resources include measured, indicated and a portion of inferred resources that are contained within a “Mineral Resource Pit” based on metal prices of $900/oz gold, $15.00/oz silver, $1.00/lb zinc and $0.75/lb lead at lower cut-offs of 0.1 g/t Au for oxide mineralization and 0.4 g/t AuEq for sulphide mineralization. Inferred resources also include potentially economic mineralization extending outside the limits of the “Mineral Resource Pit” which is delimited by lower cut-off grade shells of 0.1 g/t Au for oxide mineralization and 0.4 g/t AuEq for sulphide mineralization. |
|
4) El Morro mineral reserve and resources tonnes and grade are reported on a 100% basis; contained metals are reported on a 30% basis to reflect New Gold’s 30% ownership interest in the project.
El Morro mineral reserves and resources have been reported based on a lower grade cut-off of 0.3% copper-equivalent (“EqCu”) where
EqCu(%) = Cu(%) + 0.592 x Au (g/t) and Cu(%) = percent copper, Au(g/t) = grams per tonne gold, and 0.592 represents a constant based on metal prices of $1.25/lb copper and $500/oz gold and average metal recoveries for the deposit.

CAUTIONARY NOTE REGARDING FORWARD-LOOKING STATEMENTS
Certain information contained in this press release, including any information relating to New Gold's future financial or operating performance, may be deemed "forward looking". All statements in this press release, other than statements of historical fact, that address events or developments that New Gold expects to occur, are "forward-looking statements". Forward-looking statements are statements that are not historical facts and are generally, but not always, identified by the words "expects", "does not expect", "plans", "anticipates", "does not anticipate", "believes", "intends", "estimates", "projects", "potential", "scheduled", "forecast", "budget" and similar expressions, or that events or conditions "will", "would", "may", "could", "should" or "might" occur. All such forward looking statements are subject to important risk factors and uncertainties, many of which are beyond New Gold's ability to control or predict. Forward-looking statements are necessarily based on estimates and assumptions that are inherently subject to known and unknown risks, uncertainties and other factors that may cause New Gold's actual results, level of activity, performance or achievements to be materially different from those expressed or implied by such forward-looking statements. Such factors include, without limitation: the results of the preliminary economic assessment assessing the viability of a new process facility at Amapari; New Gold's operations are subject to significant capital requirements; fluctuations in the international currency markets and in the rates of exchange of the currencies of Canada, the United States, Australia, Brazil, Mexico and Chile; price volatility in the spot and forward markets for commodities; impact of any hedging activities, including margin limits and margin calls; discrepancies between actual and estimated production, between actual and estimated reserves and resources and between actual and estimated metallurgical recoveries; changes in national and local government legislation in Canada, the United States, Australia, Brazil, Mexico and Chile or any other country in which New Gold currently or may in the future carry on business; taxation; controls, regulations and political or economic developments in the countries in which New Gold does or may carry on business; the speculative nature of mineral exploration and development, including the risks of obtaining necessary licenses and permits; diminishing quantities or grades of reserves; competition; loss of key employees; additional funding requirements; actual results of current exploration or reclamation activities; changes in project parameters as plans continue to be refined; accidents; labour disputes; defective title to mineral claims or property or contests over claims to mineral properties. In addition, there are risks and hazards associated with the business of mineral exploration, development and mining, including environmental hazards, industrial accidents, unusual or unexpected formations, pressures, cave-ins, flooding and gold bullion losses (and the risk of inadequate insurance or inability to obtain insurance, to cover these risks) as well as "Risks and Uncertainties" included in New Gold's MD&A filed on November 12, 2008, and available at www.sedar.com. Forward-looking statements are not guarantees of future performance, and actual results and future events could materially differ from those anticipated in such statements. All of the forward-looking statements contained in this press release are qualified by these cautionary statements. New Gold expressly disclaims any intention or obligation to update or revise any forward-looking statements, whether as a result of new information, events or otherwise, except in accordance with applicable securities laws.
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.
CIM STANDARDS DEFINITIONS
The estimated mineral resources and mineral reserves for the New Afton Project, the Cerro San Pedro Mine and the El Morro Project have been calculated in accordance with the Canadian Institute of Mining, Metallurgy and Petroleum ("CIM") ? Definitions Adopted by CIM Council on December 11, 2005 (the "CIM Standards") which were adopted by the Canadian Securities Administrators' National Instrument 43-101 Standards of Disclosure for Mineral Projects ("NI 43-101"). The following definitions are reproduced from the CIM Standards:
The term "Mineral Resource" means a concentration or occurrence of natural, solid, inorganic or fossilized organic material in or on the Earth's crust in such form and quantity and of such grade or quality that it has reasonable prospects for economic extraction. The location, quantity, grade, geological characteristics and continuity of a Mineral Resource are known, estimated or interpreted from specific geological evidence and knowledge. Mineral Resources are sub-divided, in order of increasing geological confidence, into Inferred, Indicated and Measured categories.
The term "Inferred Mineral Resource" means that part of a Mineral Resource for which quantity and grade or quality can be estimated on the basis of geological evidence and limited sampling and reasonably assumed, but not verified, geological and grade continuity. The estimate is based on limited information and sampling gathered through appropriate techniques from locations such as outcrops, trenches, pits, workings and drill holes.
The term "Indicated Mineral Resource" means that part of a Mineral Resource for which quantity, grade or quality, densities, shape and physical characteristics, can be estimated with a level of confidence sufficient to allow the appropriate application of technical and economic parameters, to support mine planning and evaluation of the economic viability of the deposit. The estimate is based on detailed and reliable exploration and testing information gathered through appropriate techniques from locations such as outcrops, trenches, pits, workings and drill holes that are spaced closely enough for geological and grade continuity to be reasonably assumed.
The term "Measured Mineral Resource" means that part of a Mineral Resource for which quantity, grade or quality, densities, shape, physical characteristics are so well established that they can be estimated with confidence sufficient to allow the appropriate application of technical and economic parameters, to support production planning and evaluation of the economic viability of the deposit. The estimate is based on detailed and reliable exploration, sampling and testing information gathered through appropriate techniques from locations such as outcrops, trenches, pits, workings and drill holes that are spaced closely enough to confirm both geological and grade continuity.
The term "Mineral Reserve" means the economically mineable part of a Measured or Indicated Mineral Resource demonstrated by at least a Preliminary Feasibility Study. This study must include adequate information on mining, processing, metallurgical, economic and other relevant factors that demonstrate, at the time of reporting, that economic extraction can be justified. A Mineral Reserve includes diluting materials and allowances for losses that may occur when the material is mined.
The term "Probable Mineral Reserve" means the economically mineable part of an Indicated Mineral Resource and, in some circumstances, a Measured Mineral Resource demonstrated by at least a Preliminary Feasibility Study. This study must include adequate information on mining, processing, metallurgical, economic and other relevant factors that demonstrate, at the time of reporting, that economic extraction can be justified.
The term "Proven Mineral Reserve" means the economically mineable part of a Measured Mineral Resource demonstrated by at least a Preliminary Feasibility Study. This study must include adequate information on mining, processing, metallurgical, economic and other relevant factors that demonstrate, at the time of reporting, that economic extraction is justified.
JORC CODE DEFINITIONS
The estimated mineral resources and ore reserves for the Amapari Mine and the Peak Mines have been calculated in accordance with the current (1999) version of the Australasian Code for Reporting of Mineral Resources and Ore Reserves (the "JORC Code"), the Australian worldwide standards. The JORC Code has been accepted for current disclosure rules in Canada under NI 43-101. The following definitions are reproduced from the JORC Code:
The term "Mineral Resource" means a concentration or occurrence of material of intrinsic economic interest in or on the Earth's crust in such form and quantity that there are reasonable prospects for eventual economic extraction. The location, quantity, grade, geological characteristics and continuity of a Mineral Resource are known, estimated or interpreted from specific geological evidence and knowledge. Mineral Resources are sub-divided, in order of increasing geological confidence, into Inferred, Indicated and Measured categories.
The term "Inferred Mineral Resource" means that part of a Mineral Resource for which tonnage, grade and mineral content can be estimated with a low level of confidence. It is inferred from geological evidence and assumed but not verified geological and/or grade continuity. It is based on information gathered through appropriate techniques from locations such as outcrops, trenches, pits, workings and drill holes which may be limited or of uncertain quality and reliability.
The term "Indicated Mineral Resource" means that part of a Mineral Resource for which tonnage, densities, shape, physical characteristics, grade and mineral content can be estimated with a reasonable level of confidence. It is based on exploration, sampling and testing information gathered through appropriate techniques from locations such as outcrops, trenches, pits, workings and drill holes. The locations are too widely or inappropriately spaced to confirm geological and/or grade continuity but are spaced closely enough for continuity to be assumed.
The term "Measured Mineral Resource" means that part of a Mineral Resource for which tonnage, densities, shape, physical characteristics, grade and mineral content can be estimated with a high level of confidence. It is based on detailed and reliable exploration, sampling and testing information gathered through appropriate techniques from locations such as outcrops, trenches, pits, workings and drill holes. The locations are spaced closely enough to confirm geological and/or grade continuity.
The term "Ore Reserve" means the economically mineable part of a Measured or Indicated Mineral Resource. It includes diluting materials and allowances for losses which may occur when the material is mined. Appropriate assessments, which may include feasibility studies, have been carried out, and include consideration of and modification by realistically assumed mining, metallurgical, economic, marketing, legal, environmental, social and governmental factors. These assessments demonstrate at the time of reporting that extraction could reasonably be justified. Ore Reserves are sub-divided in order of increasing confidence into Probable Ore Reserves and Proved Ore Reserves.
The term "Probable Ore Reserve" means the economically mineable part of an Indicated, and in some circumstances Measured Mineral Resource. It includes diluting materials and allowances for losses which may occur when the material is mined. Appropriate assessments, which may include feasibility studies, have been carried out, and include consideration of and modification by realistically assumed mining, metallurgical, economic, marketing, legal, environmental, social and governmental factors. These assessments demonstrate at the time of reporting that extraction could reasonably be justified.
The term "Proved Ore Reserve" means the economically mineable part of a Measured Mineral Resource. It includes diluting materials and allowances for losses which may occur when the material is mined. Appropriate assessments, which may include feasibility studies, have been carried out, and include consideration of and modification by realistically assumed mining, metallurgical, economic, marketing, legal, environmental, social and governmental factors. These assessments demonstrate at the time of reporting that extraction could reasonably be justified.
The foregoing definitions of Mineral Resources and Ore Reserves as set forth in the JORC Code have been reconciled to the definitions set forth in the CIM Standards. If the Mineral Resources and Ore Reserves for the Amapari Mine and the Peak Mines were estimated in accordance with the definitions in the CIM Standards, there would be no substantive difference in such Mineral Resources and Ore Reserves.
