Full Description of Material Change


FEASIBILITY STUDY BACKGROUND


The FS was carried out by a team which included, and was coordinated by, Hatch Ltd. ("Hatch") which completed the processing and surface infrastructure engineering components of the study. Mine planning and reserves were completed by AMC Consultants Pty. Ltd. ("AMC"), and Scott Wilson Roscoe Postle Associates Inc. ("Scott Wilson RPA") completed the geology and resource sections. Environmental services and permitting were completed by Rescan Environmental Services Ltd. ("Rescan"). The Tailings disposal analysis was completed by Vector Engineering Inc. (“Vector”).  The groundwater modeling was carried out by Piteau Associates Engineering Ltd. (“Piteau”).  The purpose of the FS was to determine the potential for, and the technical and economic parameters of, developing the New Afton Project into a new bulk underground mining operation.


The New Afton FS was co-ordinated by Mr. John Shillabeer. P.Eng., of Hatch (who is a Qualified Person under National Instrument 43-101), and the technical content of the news release was reviewed and approved by him.  A NI 43-101 compliant Technical Report (“The Technical Report”), summarizing the FS, will be filed on SEDAR as soon as possible.  It should be noted that the capital cost estimate, operating cost estimate, and economic analysis described are subject to important qualifications, assumptions and exclusions, all of which will be set out in the Technical Report.  To fully understand the cost estimates and economic analysis the Technical Report should be read in its entirety.


PROJECT SUMMARY


The New Afton Project is host to a Cu-Au porphyry, which is among the highest grade in the world of this deposit type.  It is the site of a former open pit Cu-Au operation (the Afton Mine) which operated from 1978 to 1987, producing approximately 500 million pounds of Cu, 500,000 ounces of Au, and 3 million ounces of Ag.  In 1999 New Gold acquired the mineral rights through staking.  An exploration program from 2000–2003 outlined an extensive body of high grade Cu-Au porphyry style mineralization, which a 2004 Scoping Study indicated had the potential to become a new underground mine.  A 2005 underground exploration program completed more than 2 kilometers of tunneling, which provided access to complete infill drilling and conduct geotechnical analysis.  The data gained from this work was used to undertake the FS, which commenced at the end of 2005.

The FS has confirmed that the New Afton Project is economically and technically feasible as an underground block cave mine.  Access will be by ramp from surface.  The initial construction period will be approximately 2 years in order to reach commercial production in the second half of 2009.  Upon start-up, production will be at an annualized rate of 1.6 million tonnes per year for 2 years.  During this time ore will be trucked to surface and processed on site to produce a concentrate, which will be transported by rail, either to smelters in Eastern Canada, or to Vancouver and then by ship to smelters in Asia.  Once the ramp-up period is complete the full production rate will be 4 million tonnes per year, making it one of Canada’s largest underground metals mines (based on ore production rate).  From that time onward, ore will be crushed underground before being transported to surface by conveyor.  For the entire mine life, tailings will be deposited in a new facility, constructed from cycloned tailings.  Water will be supplied initially from the Afton open pit, and thereafter from Kamloops Lake to the north.


The mine plan is based around 3 cave blocks.  Mining will commence from the central block (block 2), as this will allow time to remove water from, and stabilize accumulated rock debris at the bottom of, the Afton pit.  The eastern and western blocks 1 and 3 will be mined simultaneously.


In order to be in a position to expedite development, Cementation Canada Inc., who has been appointed as the underground mining contractor, is currently mobilizing to site, and is scheduled to commence underground work at the beginning of April.  In addition, the Company has commenced the process of ordering the longest lead-time item, which is the 11,000 tonne per day SAG Mill, by committing to the principal components by making required cash payments.


PROJECT ANALYSIS


The FS uses the 3-year trailing (2/1/04 to 1/1/07) average LME spot metal prices and exchange rates for the economic analysis, which are Cu US$2.01/lb; Au US$487/oz; and Ag US$8.54/oz, and a CDN:US$ exchange rate of 0.82 (and is based on constant dollars without escalation).

MINERAL RESOURCE ESTIMATE


All Mineral Resources were estimated by Qualified Person (under National Instrument 43-101)  David Rennie of Scott Wilson RPA.  The Measured and Indicated resource, which was used as the basis for estimating the reserve, was released on September 21, 2006. This estimate was made by Ordinary Kriging, and used the information from drilling completed at the project since 2000.  This included 90 surface holes, totalling 42,450 metres (m), drilled during the period 2000 to 2003, and 65 underground holes, totalling 25,805m, completed from the exploration decline in 2005.  In estimating the resource, the following metal prices were used - Copper (Cu) US$1.20/lb; Gold (Au) US$450/oz; and Silver (Ag) US$5.25/oz.

   

Mineralization, in the Measured and Indicated categories, occurs over a length of approximately 1000m, to a depth of approximately 800m below surface, with the bulk of it contained within a Main Zone trending southwest, and which averages approximately 100m in



- 6 -



 

width and 350m in height.  In places, the width and height of mineralization can reach in excess of, respectively, 150m and 500m.  Smaller amounts of mineralization are present in parallel lenses (“Hanging Wall Lenses”) to the south of the Hanging Wall Fault .  


This resource estimate has been constrained within mineralogical and geological boundaries.  Mineralization occurs within a structural corridor outlined by the well-defined Hanging Wall Fault (to the south), and the less well-defined Footwall Fault (to the north).  In places the Hanging Wall Fault truncates the mineralization.  The boundaries of the mineralization are generally clearly defined between the higher grades of the resource and distinctly lower grades of the surrounding rocks.  This lower grade enveloping mineralization was not included within the resource estimate, as it was considered unlikely that it would become economic at any currently reasonable metal price assumptions.  Three zones of mineralization were noted  – 1) Hypogene (primary mineralization), with chalcopyrite and lesser bornite being the dominant Cu-bearing minerals; 2) Mesogene, where chalcocite is the dominant Cu-bearing mineral with lesser chalcopyrite; and 3) Supergene, where native Cu, and minor chalcocite, is present.  Hypogene comprises approximately 52% of the total resource tonnage, Mesogene 39%, and Supergene 9%.

Subsequently (on March 20, 2007) the Company released an Inferred resource for mineralization outlined vertically below the Main Zone resource described previously.  This mineralization is called the C Zone.  This Inferred resource was estimated from the results of 11 underground diamond drill holes and 1 surface hole.  The mineralization is all Hypogene, or primary, with chalcopyrite being the dominant Cu-bearing mineral.  The drill density was sufficient only to place the resource in the Inferred category.  Additional infill drilling will be required to increase the confidence level in the resource and upgrade it to the Indicated and/or Measured categories.

The C Zone mineralization is contained within 2 separate blocks (east and west) which cover a combined total strike length of approximately 700 metres (m), and each of which has a maximum vertical extent of more than 300m.  The lower limit of the mineralization is constrained by available information, and it remains open at depth.  Additional drilling below the resource is required to determine the true extent of the C Zone.  The Company is currently assessing potential options to conduct this work.  Relative to the Main Zone, the C Zone has higher gold grades, but lower copper grades.


Of the 2 blocks, the western one is the more significant with greater widths and higher grades.  The eastern block is separated from the Main Zone, while the western block is, in places, contiguous with the Main Zone.


MINERAL RESERVE ESTIMATE


Reserves were estimated by Qualified Person (under National Instrument 43-101) Mike Thomas MAusIMM(CP) of AMC, and utilized the Measured and Indicated resource model described above.  The starting point for estimating the reserve was an analysis of the mineralization contained within the resource model (excluding the C Zone), which AMC broke down into the following components – East Block, West Block, and Pit Protection Pillar in the Main Zone, and the Hanging Wall Lenses - as illustrated in attached plan view of resource block model (Figure 2).  To this breakdown, AMC applied knowledge gained from all geotechnical data, in addition to geological interpretations of faults and other structures.  In estimating the reserves, the following metal prices were used - Copper (Cu) US$1.45/lb; and Gold (Au) US$475/oz.


As the Hanging Wall Lenses are lower grade, isolated from the Main Zone and would require separate underground infrastructure, they were not considered in the FS.  The Main Zone was split into the east and west blocks by an area of lower grade mineralization that was not included in the reserve.  A decision was made to leave a pillar under the west area of the pit (Pit Protection Pillar), as the mineralization was slightly lower grade than the bulk of the main zone and, because of its higher elevation, could not easily be recovered within the same block cave panel as the East Block (Block 1).  This pillar was not considered in the reserve estimation.




- 8 -



 

AMC determined that the Main Zone mineralization could be mined as three cave areas, Block 1 (B1) and Block 2 (B2), separated by a low-grade pillar would have the same cave base, whilst Block 3 (B3) would have its base at a lower elevation.


To enable a single cut-off parameter to be used when selecting the economic parts of the resource to be mined, AMC estimated the theoretical value (Value) received for concentrate produced from each tonne of resource, assuming that the concentrate is sold at the mine gate. All costs and losses incurred in the off-site transportation and processing of concentrate being the responsibility of the buyer.


The block caving method requires the orebody to be undercut enabling the ore to collapse and fragment (cave) into underlying drawpoints where it is extracted.  The shape and size of the area to be undercut (the footprint) was determined by comparing a nominated cost of establishing each drawpoint (CDN$300,000) with the total recoverable value of the overlying column of ore, after deducting mining, processing and all other site costs. The footprint was designed to encompass those drawpoints with a positive net value and, where necessary, a number of sub-economic drawpoints to ensure that the undercut area was large enough to cave, (determined by geotechnical investigations as being an area with a minimum span in any direction of approximately 95m).  


As a result of establishing the most suitable block cave footprints, some areas of remnant mineralization remain beneath the cave outlines, and were, therefore, not included in the reserve.  


To determine the heights of the caved ore columns, AMC used two separate simulation programs (Cave-Sim, and PC-BC). on the block model, analyzing individual columns with a base area of 13m x 13m. These programs model the progressive mixing of various mineralized and unmineralized materials within the cave as the orebody is mined.  Once the value of the ore being extracted from the drawpoint reached less than CDN$15 per tonne the programs determined the cave column had been drawn to its maximum economic height (at the metal prices used in the reserve calculation) and the drawpoint was closed.


The mineral reserve estimate is summarized below and results from mixing of measured and indicated resources with dilution from low-grade and barren material from within the cave outline and from the overlying material entering from above.  The reserve also takes account of mineralized material that would be uneconomic to recover at the metal prices used for the reserve estimation and would remain in the cave.  The net effect is a dilution of approximately 15% of the original mineral resource within the cave outlines.

Although a large volume of mineralization encompassed by the projected footprint has a Measured Resource classification, a Probable Reserve classification has been assigned because of the uncertainty in predicting the material movement within the cave and the absence of any historical information to provide a reconciliation of actual versus forecast grades to provide more detailed guidance.  Also, a large quantity of indicated resource and unclassified material mixes with the measured resource within the cave. As it is not possible to mine the measured resource separately from this material, the effect is to lower the classification of the total reserve. This is not unusual practice when completing reserve estimates for block cave mines.


METALLURGY


The processing facilities have been designed to treat 4.0 million tonnes per year and recover copper, gold and silver values. A conventional crushing, grinding, gravity concentration and flotation circuit has been designed utilizing standard unit processes and equipment.  The process design criteria have been based on a combination of testwork results, experience from similar operations and industry practice.


A concentrate containing Cu, Au, and Ag will be produced on site at the New Afton Project.  The metallurgical characteristics of the various ore types (Supergene, Mesogene and Hypogene) are summarized in Table 10 below.


Penalty elements (Arsenic and Mercury) are associated with the Mesogene and Supergene mineralization which are located within the eastern block (#1).  The Hypogene ore of the central and western blocks (#’s 2 and 3) do not contain any meaningful quantities of these penalty elements.  The mine plan is designed to have Block 1 mined simultaneously with Block 3 such that the blend of the various ore types reduces the concentration of penalty elements.


With the FS now complete, the Company will engage in more detailed discussions with smelters in order to secure off-take arrangements for the concentrate.

INFRASTRUCTURE


The surface infrastructure and facilities will be located in a relatively flat area to the west of the Afton open pit and will be connected by a 2 km road to an existing junction on the Trans-Canada Highway. There will be three major buildings and a number of smaller structures. Power will be supplied by a 300m connection to the BC Hydro 138 kV grid located to the north of the Trans-Canada Highway.


The mill will initially utilize water stored on site in the Afton and Pothook open pits, which will last approximately two years. Fresh water will initially be pumped from Kamloops Lake via an existing pump station and pipeline for potable use and then as process make up water once on-site sources are depleted.


Water and tailings management have been designed to achieve zero discharge from the site. The existing Afton pit and future cave provide a sink for groundwater run off and seepage collection.

PERMITTING


Earlier this year New Gold submitted the formal Mines Permit application.  The application was made under the Mines Act (BC), and is for the approval of both the Mine Plan and Reclamation Program. The Mines Act review and approval process is administered through the multi-agency South-Central Mine Development Review Committee ("SCMDRC") which is responsible for coordinating the permitting requirements of its member agencies. The application is currently being reviewed by these agencies. In addition, presentations have been made to the local First Nations, and to the public. At the conclusion of this review period, the SCMDRC will prepare a recommendation report which will be submitted to the Chief Inspector of Mines for a permit decision. Additional permits which are required as project construction moves forward will be applied for as necessary.


The permit application process is continuing well.  Currently, the Company is addressing the questions which have been put forward by various parties, including relevant government agencies.  In addition, the Government of B.C. is conducting its required consultations with the local First Nations communities (Kamloops Indian Band and Skeetchestn Indian Band).


CAPITAL COSTS


The capital costs for the development of the project can be broken down into three distinct phases as shown in Table 11: Pre-Production (approximately 24 months), Expansion to 4.0 mtpa production (approximately 24 months) and sustaining for the remainder of the mine  life.

MINERAL AND SURFACE TENURE


New Gold holds the mineral rights to an area totaling 903 hectares, which surrounds the New Afton mineralization as a Mining Lease (Tenure # 546063).  The lease is for a 30 year renewable term, and represents the most secure form of mineral tenure in British Columbia.  In addition, New Gold holds 100% of the mineral rights as mineral claims in an area totaling approximately 4,462 hectares immediately to the north of the mining lease.  Approximately 10 km to the southeast, the Company holds 100% of the mineral rights as mineral claims in the Ajax Property covering an area totaling approximately 6,078 hectares, which surrounds the past-producing Ajax open pit mine.


Earlier this year (January 9, 2007) New Gold announced it had signed a Letter of Intent (“LOI”) with Teck Cominco Limited (“Teck”) to acquire surface rights to more than 4,000 acres of land, encompassing the New Afton Project.  This land is located within the Company’s mining lease and mineral claims.  It encompasses all of the land south of the Trans-Canada Highway which covers the site for the proposed development of the New Afton Project into an underground mine.  Additionally, it includes a large area of land north of the Trans-Canada Highway to Kamloops Lake.  The majority of the land is fee simple, meaning that, upon completion of the acquisition, New Gold will own the land outright.  The remainder (which overlies the location of most of the surface facilities for the proposed New Afton mine development) is Crown land currently held by a Teck subsidiary as a grazing lease.  Upon completion of the acquisition, this leased land will be held by New Gold.

To complete this acquisition New Gold will pay Teck CDN$10 million upon closing, with an additional CDN$6 million to be paid (with applicable interest) any time within 2 years of closing.  Teck will also be granted a 2% Net Smelter Return over the New Afton Copper-Gold Project, which New Gold has the option to repurchase for CDN$12 million.  Completion of the transaction described in the LOI is subject to definitive documentation, receipt of any necessary regulatory approvals and customary conditions of closing.  New Gold and Teck have agreed to work towards this as expeditiously as possible.  

 

PROJECT FINANCING


On August 16, 2006, New Gold announced that Barclays Capital (“Barclays”) had been appointed as lead arranger for the debt portion of any project financing to develop the New Afton Project into a mine.  With the completion of the FS, the Company is now focused on exploring all avenues to secure the financing required to develop the project into a new underground mine, including continuing its discussions with Barclays.

OPPORTUNITIES


Potential opportunities which have the potential to improve the New Afton project economics include the following.  The Company will continue to examine ways in which the project can potentially be improved, optimized and increased in size.


C Zone Resource – conversion of the Inferred Resource through additional drilling to Measured and/or Indicated classification, which could add additional life, and/or operating flexibility to the operation.


Earlier Ramp Up to 4 Million Tonnes per Year (Mt/y) – the project schedule provides 2 years of lower mill throughput (1.6 Mt/y).  If cave initiation and and early operations are sufficiently successful, this ramp up period may be reduced which would bring forward the production rates and revenue associated with the 4 Mt/y levels.


Optimize Cave Draw Schedule – there is scope to further optimize the cave draw schedule to mine higher grade material earlier.


Addition of Sub-Level Caving – the resource narrows below the cave outline.  Extraction of these resources using sub-level caving after completion of the overlying block cave extraction may be possible, depending on metal price assumptions.
