Mineral Reserve and Resource Estimate
Mineral Resource
The Rainy River mineral resource, effective November 2, 2013, is reported in relation to a conceptual open pit shell at a gold cut-off of 0.30 grams per tonne for open pit resources and a gold cut-off value of 2.5 grams per tonne for underground resources. Globally, the deposit contains Measured and Indicated mineral resources suitable for direct processing, from mine to mill, of 106 million tonnes at 1.54 grams per tonne gold and 2.88 grams per tonne silver, representing 5.2 million ounces of gold and 9.8 million ounces of silver. In addition, the open pit Measured and Indicated mineral resources suitable for stockpiling and future processing total 71 million tonnes at 0.43 grams per tonne gold and 2.09 grams per tonne silver, representing 1.0 million ounces of gold and 4.8 million ounces of silver. A table summarizing the mineral resource, including key assumptions, is included at the conclusion of this news release in the section entitled Technical Information.
This mineral resource estimate has been completed by SRK Consulting (Canada) Inc. ("SRK") in conformity with generally accepted CIM "Estimation of Mineral Resource and Mineral Reserves Best Practices" guidelines and is reported in accordance with Canadian Securities Administrators' NI 43-101 (as defined at the conclusion of this release). The mineral resource estimate is based upon a geologic block model that incorporates 382,182 individual assays from over 742,000 metres of core from 1,656 drill holes. Assay data density is sufficient to classify the mineral resource at the Measured and Indicated confidence levels as necessary to support the estimation of a mineral reserve. SRK has conducted a series of routine verifications to ensure the reliability of the quality assurance/quality control for the drill assay data supporting the Rainy River mineral resource. Through SRK's independent review, it has been concluded that the field samples and assaying procedures meet industry best practices and that assay grades can be reasonably reproduced, indicating that the primary assay laboratories are sufficiently reliable for the resource estimation used in the Feasibility Study.
Mineral Reserve
A proposed mining production schedule was developed through the design of a combined open pit and underground mine within the mineral resource model. The Rainy River mineral reserve, which represents the portion of Measured and Indicated mineral resources included in the production schedule, has been diluted using an average of 4.0% additional tonnes containing 0.21 grams per tonne gold and 1.19 grams per tonne silver for the open pit and an average of 11.7% for the underground stoping, which includes dilution from both overbreak and backfill dilution. Including the development ore, the total underground dilution averages 8.3%. The open pit mineral reserve estimate has been completed by BBA Inc. and the underground mineral reserve estimate has been completed by AMC Mining Consultants (Canada) Ltd. The Rainy River mineral reserve is summarized in the following table.

Notes: |
1. Open pit mineral reserves have been estimated using an optimized pit shell based on metal prices of $800 per ounce gold and $25 per ounce silver, a foreign exchange rate of CAD $1.05 to USD $1.00, gold recovery of 89.9% (non-CAP Zone) and 74.3% (CAP Zone) and a silver recovery of 67.1% (non-CAP Zone) and 69.5% (CAP Zone). The cut-off grade is based on a gold price of $1,200. Underground reserves have been estimated from mining shapes generated using a cut-off grade of 3.5 g/t gold-equivalent. Development material from stope access drives above a cut-off grade of 1.5 g/t gold-equivalent is also assumed to be sent to the mill for processing. Underground breakeven cut-off grade is calculated at 2.75 g/t gold-equivalent based on metal prices of $1,300 per ounce gold and $22 per ounce silver, a foreign exchange rate of CAD $1.05 to USD $1.00, gold recovery of 95% and a silver recovery of 75%. 2. Open pit reserves have been estimated using a dilution of 4% at 0.21 g/t Au and 1.19 g/t Ag, and Underground reserves have been estimated using an overall dilution of 8.3%, inclusive of both rock and backfill dilution. Open pit and underground reserves have been estimated using a mining recovery of 95% and 96.5%, respectively. 3. Open pit direct processing material is defined as mineralization likely to be mined and processed directly and above a variable cut-off grade ranging from 0.3-0.7 Au g/t. 4. Stockpile material includes all material within designed open pit between variable cut-offs described above in Note 3, as well as material within the CAP zone (code 500) that is suitable for stockpiling and future processing. 5. Mineral Reserves for the open pit are derived from the resource model effective November 2, 2013. Models for the underground reserves were derived from the August 2013 and September 2013 models for the main ODM zone and Intrepid Zone, respectively. Models were prepared by Dorota El-Rassi, P.Eng. (APEO #100012348) and Glen Cole, P.Geo. (APGO #1416), of SRK, both independent "Qualified Persons" as that term is defined in Canadian National Instrument 43-101. Rainy River's exploration program in Richardson Township is being supervised by Mark A. Petersen, (AIPG Certified Professional Geologist #10563), Vice President, Exploration for New Gold and a "Qualified Person" as defined in Canadian National Instrument 43-101. New Gold continues to implement a rigorous QA/QC program to ensure best practices in drill core sampling, analysis and data management. 6. Qualified persons - The open pit portion of the mineral reserve statement was prepared under the supervision of Patrice Live (OIQ #38991) of BBA, and the underground portion of the mineral reserve statement was prepared by Colm Keogh, P.Eng. (APEGBC #37433) of AMC Mining Consultants (Canada) Ltd., both independent "Qualified Persons" as that term is defined in Canadian National Instrument 43-101. 7. The mineral reserve estimate may be materially affected by environmental, permitting, legal, title, taxation, sociopolitical, marketing, and other relevant issues. |
Mining Operations and Metallurgy
Conventional open pit mining has been chosen as the primary method to mine the Rainy River deposit given the proximity of mineralization to the surface. Deeper, higher grade portions of the deposit will be mined from underground. The open pit mining production schedule incorporates an elevated cut-off grade strategy during the first nine years of mining to increase the mill feed grade. Material below the elevated cut-off grade will be stockpiled for processing during the later years of the Project life. In addition, upon the start of production from the open pit, the development of the underground mine would commence with initial production from underground expected in 2018. The targeted mill throughput of 21,000 tpd will initially be sourced exclusively from the open pit and then, once in full production, the underground mine will contribute 1,500 tpd of ore, with the balance of the 19,500 tpd coming from the open pit.
Open Pit Operations
At full capacity, open pit mining operations would be carried out with an equipment fleet comprising: three 216 millimetre blast hole drills, one 29 cubic metre and two 26 cubic metre hydraulic shovels, one 18 cubic metre wheel loader and 22 - 220 tonne haul trucks. A 10 metre bench height has been selected for mining. The open pit mine would provide process plant feed starting at a nominal rate of 21,000 tpd, or 7.7 million tonnes per year, declining to 19,500 tpd, or 7.1 million tonnes per year, once the underground mine reaches its full production. Total annual mining of ore, waste and overburden would peak at 69 million tonnes. The operational stripping ratio, excluding waste and overburden stripping during the development phase, is 3.5:1.0.
Underground Operations
The underground mine will be accessed via a four kilometre decline from a surface portal located to the east of the open pit. The underground design supports the ultimate extraction of 1,500 tpd of ore by longitudinal longhole open stoping. The underground mineralization occurs in sub-vertical horizons varying in width from approximately three metres to 20 metres, with the weighted average width across the various zones being approximately eight metres. The various areas of underground mineralization provide for flexibility in the production schedule to recover higher grade material earlier in the mine life. Longitudinal longhole open stoping in each zone will proceed in a retreating pattern from the strike extent of ore to a common access point on all levels. Mining is scheduled to proceed upwards from the lowest level of the zone, or from an adopted sill elevation, with backfill providing the working platform for each successive lift. On average, stopes eight metres in width, 20 metres in length and 20 metres in height have been used for mine planning. At full capacity, ore handling from underground workings to surface will be accomplished through a fleet of four 7 cubic metre loaders and six 45 tonne haul trucks.
Metallurgy
The metallurgical evaluation was supported by an extensive grinding and extraction test program. Comminution tests were conducted on drill hole composites selected via geometallurgical methodology to ensure representative process plant feed, from both the open pit and underground, as well as to investigate the impact of variability in hardness on the crushing and grinding circuit design. The composites were derived from over 170 exploration drill holes and 13 dedicated large bore HQ/PQ drill holes. Mineralogical and diagnostic leach tests were conducted on approximately 120 composite samples. The test work determined the base flowsheet as well as the optimum leaching parameters. An additional 275 variability leach tests were then conducted on specific geometallurgically selected drill core composite samples to investigate the impact of the selected leaching parameters on the various ore zones throughout the deposit. Estimated process plant feed grade, recoveries and metal production from commercial production forward are summarized below.

Mineral Processing
The 21,000 tpd process plant would use conventional crushing, grinding, leaching, carbon-in-pulp ("CIP") and gold recovery technology to produce gold-silver doré. The overall design utilizes a simple and conventional flowsheet.
Run-of-mine material will be crushed to 165 millimetres in the gyratory crusher and subsequently conveyed and ground in the SAG mill in closed circuit with a scalping screen and a pebble crusher. Undersize from the scalping screen will be combined with the ball mill discharge and pumped to a cyclone cluster. The underflow from the cyclone cluster will feed the ball mill. A portion of the ball mill discharge will be treated by a gravity circuit. The cyclone overflow will be thickened in a pre-leach thickener and pumped to the cyanide leaching circuit, which is designed for approximately 30 hours retention time. The discharge from the leach circuit will flow by gravity to a CIP circuit where the leached gold will be adsorbed onto carbon. Loaded carbon will be sent to the carbon stripping circuit where the gold and silver will be recovered as sludge in electrowinning cells then filtered, dried and smelted into doré bars.
The tailings from the CIP circuit will be sent to the cyanide destruction circuit and then discharged into the tailings storage facility.
Key process equipment would consist of:
- A 1,371 x 1,950 millimetre (54" x 75") gyratory crusher
- A SAG/ball mill/crusher grinding circuit:
- One 11.0 x 6.1 metre diameter (36' x 20') 15-Megawatt SAG mill
- One 7.9 x 12.3 metre diameter (26' x 40.5') 15-Megawatt Ball mill
- One 448-Kilowatt pebble crusher
- One 45 metre diameter pre-leach thickener
- Whole ore leaching and CIP circuit:
- Eight leach tanks of 18 metre diameter
- Seven 360 cubic metre capacity CIP tanks
- One 45 metre diameter pre-detox thickener
Project Capital Costs
The Project is located 50 kilometres northwest of Fort Frances, a town with a population of approximately 8,000 people, in northwestern Ontario. The Project benefits from its proximity to existing infrastructure. Hydroelectric power will be sourced through the construction of a new 17 kilometre transmission line that will connect the Project to a pre-existing 230 kV line that currently links Fort Frances and Kenora, Ontario, a small city with a population of approximately 15,000 people, located to the north of the Project.
The Rainy River project site is easily accessible by a network of all-weather roads that branch off the well-maintained Trans-Canada Highways 11 and 71. Access roads are serviced, allowing year-round access. The Canadian National Railway is located 21 km to the south of the Project and runs east-west.
During the initial development stage, the direct on-site personnel requirement peaks at approximately 450 people. As a result of the Project's proximity to various towns, no camp facilities are envisioned during the construction or operational phase. The underground mine is scheduled to be developed once the open pit begins production. Development capital costs related to the underground mine are included in the sustaining capital estimate.
The total estimated development capital cost for the Project is $885 million inclusive of a $70 million contingency. The estimated development capital cost is based on the fourth quarter 2013 capital environment. The development capital cost equates to $260 per recoverable gold ounce over the current reserve life of the Project. Total sustaining capital over the life of the Project is estimated to be $348 million, which includes $105 million related to the development of the underground mine. In total, the sustaining capital, including the development of the underground, is equivalent to an annual average of $102 per recoverable gold ounce over the current life of the Project.

Project Operating Costs
Rainy River's combined open pit and underground operation delivers strong gold head grades which, when combined with the Project's proximity to infrastructure and silver by-product revenue, results in Rainy River's estimated total cash costs(1) and all-in sustaining costs(2) being well below today's industry average.
After the start of commercial production, the Project's mining costs are projected to be C$2.04 per tonne of material for the open pit and C$90.10 per tonne of material for the underground. Costs per tonne milled over the life-of-mine are summarized below.

- Every $50 million change in development capital costs, where all other assumptions are held constant, results in a $46 million change in pre-tax NPV and 1.3% change in pre-tax IRR
Tax Considerations
Part of New Gold's growth strategy, including the successful acquisition of Rainy River Resources in 2013, has been to build its business in jurisdictions where it already has an established presence. One of the many benefits of this approach is that it enables the company to manage its business in a tax-efficient manner. In the case of Rainy River, New Gold plans to implement tax planning strategies that would allow it to realize tax synergies by utilizing a portion of the tax attributes that have been, and will continue to be, generated in the corporate entity holding the company's portfolio of Canadian assets. Currently, the company's primary objective is to maximize the cash flow generation of its New Afton Mine in Kamloops, British Columbia, with any remaining tax attributes planned to be used to maximize Rainy River's future after-tax cash flow. As New Gold's focus in such allocation will be maximizing the company's overall profitability rather than that of any one operation or project, this will remain a dynamic process.
At the end of 2012, on a combined basis, the New Gold corporate entity had over $900 million in Canadian Exploration Expenditures, Canadian Development Expenditures and Class 41 capital cost allowance as well as over $100 million in net operating losses. These totals exclude those attributes specifically related to the Blackwater project. In addition, the company's annual corporate administration expenses are approximately $30 million and its annual interest expenses are $52 million, both of which can be combined with the above noted attributes to shelter taxable profits from one or both of New Afton and Rainy River going forward. New Gold intends to implement tax planning strategies that would allow it the flexibility to access the existing tax attributes of Rainy River Resources and utilize them in a manner which would maximize New Gold's overall profitability.
For purposes of calculating the base case Rainy River after-tax economics, the company has assumed the Ontario Provincial and Federal taxes noted below as well as the distribution of the above-noted tax attributes as between Rainy River, New Afton and New Gold's other operations in a manner that first maximizes New Afton's life-of-mine cash flow generation based on the current New Afton mine plan.
- 10% Ontario provincial income tax on taxable income
- 10% Ontario mining taxes on mining income
- 2.7% Ontario corporate minimum tax
- 15% federal income taxes on taxable income
These assumptions result in the below after-tax economics for the Project.

2014 Feasibility Study Key Parameters
The results of the 2014 Rainy River Feasibility Study, including life-of-mine capital costs, average annual production and costs and project economics, are all consistent with those developed by New Gold in connection with its acquisition of Rainy River Resources in 2013. Additional detail on the key Project parameters, including changes in certain assumptions since Rainy River Resources' May 2013 study, is provided below:
Life-of-mine capital costs
- Increase in development capital costs primarily attributable to New Gold's plan to purchase, rather than lease, equipment and more conservative assumptions on labour productivity and rates
- Decrease in sustaining capital costs primarily attributable to above-noted plan to purchase equipment and reclassification of certain overburden and waste stripping costs from sustaining capital to operating costs
- In Canadian dollar terms, the total life-of-mine capital costs, including development and sustaining capital for both the open pit and underground, have increased by 8% when compared to the May 2013 study, which has been offset by an 8% depreciation in the Canadian dollar from US$/C$0.99 at the time of the 2013 study results announcement to US$/C$0.91 today
Production
- Increased underground mineral reserves, from inclusion of Intrepid zone, and updated mine planning has resulted in contribution from higher grade underground now reaching 1,500 tpd rate
- Life-of-mine total underground gold production increased by 148,000 ounces
- Life-of-mine total open pit gold production decreased by 391,000 ounces due to more conservative approach of using 10 x 10 x 10 metre blocks for modelling rather than the 5 x 5 x 5 metre blocks used previously
Operating Costs
- Minimal 5% increase in open pit mining cost per tonne mined, despite above-noted overburden and waste stripping costs being reclassified as mine operating costs
- Increase in underground mining cost per tonne resulting from updated mine planning and more conservative assumptions on productivity and rates
- Increase in processing costs due to increased electricity rate assumption of C$0.065 per kilowatt hour
- Lower all-in sustaining costs(2) during the first nine years as a result of the decrease in sustaining capital more than offsetting the increase in operating costs
Environment, Permitting and Corporate Social Responsibility
New Gold is an active member of the local community with offices in both Emo and Thunder Bay, Ontario that offer residents easily accessible locations to learn about the Rainy River project. The company has engaged the local communities, as well as local First Nations and Métis community members in its Project planning activities.
Environmental aspects have figured prominently in the development of the layouts and designs for the Rainy River project. Among other aspects, this includes consideration of the implications of design alternatives from an environmental management perspective, with a particular focus on mineral waste management, as well as the siting and location of facilities and infrastructure. From an environmental perspective, the Rainy River project is unique in that there are no lakes located within, or adjacent to, the Project. Based on multiple years of aquatics baseline investigations, with the exception of some limited baitfish harvesting, the area streams do not support a significant commercial or recreational fishery. There is considerable environmental baseline information currently available regarding the site and the surrounding area, compiled through extensive field investigations conducted over a four-year period. This information is being augmented as appropriate to support the progressing engineering design.
New Gold plans to operate the Project in accordance with the International Cyanide Management Code.
The Rainy River project is being reviewed through a coordinated Federal Environmental Assessment ("EA") - Provincial Individual EA process. During the second and third quarters of 2013, the draft EA report was reviewed by local First Nations and Métis groups, Federal and Provincial regulatory agencies and other stakeholders. All comments received were addressed and a final EA report was submitted on December 3, 2013 for Federal conformity review. On December 12, 2013, the company was informed that the final EA report had successfully passed the Federal conformity review step. This milestone enables the company to move forward with the next step in the review process as planned. Consistent with the Project schedule, the final EA report is being issued to the Federal and Provincial agencies, the local First Nations and Métis groups and other stakeholders in the coming days to complete the second consultation engagement.
The objective of final reclamation for the Rainy River project is to return the site to a productive condition on completion of mining activities. A conceptual closure plan consistent with regulatory requirements was part of the draft EA report issued for review in 2013 and is also included in the final EA report. Consistent with the Ontario Mining Act requirements, the formal Mine Closure Plan document will be submitted later in 2014 for proposed filing concurrent with the decision on the Provincial Individual EA. As much as possible, reclamation will be completed progressively during operations, consistent with industry best practices.
Once in full operation, Rainy River is expected to create approximately 600 permanent jobs. The construction work force would be approximately 450 people. New Gold is committed to maximizing local employment and contracting opportunities. The company plans to work collaboratively with community partners to prepare local workers and establish programs for specific training where necessary.

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 news release are Canadian mining terms as defined in accordance with National Instrument 43-101 ("NI 43-101") under guidelines set out in the Canadian Institute of Mining, Metallurgy and Petroleum ("CIM") Definition Standards for Mineral Resources and Mineral Reserves adopted by the CIM Council on November 27, 2010. While the terms "Mineral Resource", "Measured Mineral Resource", "Indicated Mineral Resource" and "Inferred Mineral Resource" are recognized and required by Canadian securities 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 pre-feasibility 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 Definition Standards differ in certain respects from the standards of the United States Securities and Exchange Commission.

Notes: |
1. Mineral resources are reported in relation to conceptual pit shells and are inclusive of the Intrepid zone. Vertical limit of -150m msl. 2. Open pit mineral resources are reported at a cut-off grade of 0.30 gpt gold, underground mineral resources are reported at a cut-off grade of 2.5 gpt gold based on a gold price of $1,400 per ounce, a silver price of $24.00 per ounce, a foreign exchange rate of C$1.10 to US$1.00, gold recovery of 88% for open pit resources and 90% for underground resources with silver recovery at 75%. 3. Direct processing material is defined as mineralization above a cut-off of 0.45 g/t gold and likely to be mined and processed directly. 4. Stockpile material includes all material within conceptual pit shells in the gold grade range 0.30 - 0.45 gpt as well as all material within the CAP zone that is suitable for stockpiling and future processing based on average metallurgical recoveries of 88% gold and 75% silver. 5. Qualified Persons - The mineral resource statement was prepared by Dorota El-Rassi, P. Eng. (APEO #100012348) and Glen Cole (APGO #1416) from SRK, both independent "Qualified Persons" as that term is defined in National Instrument 43-101. 6. Mineral resources are inclusive of mineral reserves. Mineral resources that are not mineral reserves do not have demonstrated economic viability. 7. The mineral resource estimate may be materially affected by environmental, permitting, legal, title, taxation, sociopolitical, marketing and other relevant issues. |
Non-GAAP Measures
(1) TOTAL CASH COSTS
"Total cash costs" per ounce figures are non-GAAP measures which are calculated in accordance with a standard developed by The Gold Institute, a worldwide association of suppliers of gold and gold products and included leading North American gold producers that ceased operations in 2002. Adoption of the standard is voluntary and the cost measures presented may not be comparable to other similarly titled measures of other companies. New Gold 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-GAAP measure. Total cash costs presented do not have a standardized meaning under GAAP 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 GAAP and is not necessarily indicative of operating costs presented under GAAP.
(2) ALL-IN SUSTAINING COSTS
Consistent with guidance announced in 2013 from the World Gold Council, an association of various gold mining companies from around the world of which New Gold is a member, New Gold defines "all-in sustaining costs" per ounce as the sum of total cash costs, sustaining capital expenditures, corporate general & administrative costs, capitalized and expensed exploration that is sustaining in nature and environmental reclamation costs, all divided by the ounces sold to arrive at a per ounce figure. New Gold believes this non-GAAP measure provides further transparency into costs associated with producing gold and will assist analysts, investors and other stakeholders of the company in assessing the Rainy River project's expected operating performance, ability to generate free cash flow and its overall value. This data is furnished to provide additional information and is a non-GAAP measure. All-in sustaining costs presented do not have a standardized meaning under GAAP and may not be comparable to similar measures presented by other mining companies. It should not be considered in isolation or as a substitute for measures of performance prepared in accordance with GAAP and is not necessarily indicative of operating costs presented under GAAP.
