SUMMARY

AMEC Americas Ltd (AMEC) was commissioned by Mountain Province Diamonds Inc. (MPV) to provide an independent Qualified Persons Review and Technical Report (the Report) of the Gahcho Kué Kimberlite Project (the Project), located in the
Northwest Territories, Canada.

The Project is a joint venture between De Beers Canada Inc. (De Beers), and MPV. De Beers holds 51% of the Project and is the operator.

For the purposes of this Report, the name Gahcho Kué Joint Venture (GKJV) is used for the joint venture vehicle.

This report describes an updated Mineral Resource estimate on the Project that incorporates information from geological and diamond revenue data updates that were completed for the Project since the previous Technical Report in 2003. AMEC
understands that MPV will be using the Report in support of a press release dated 26 May 2009, entitled Mountain Province Diamonds Announces Updated Mineral Resource Estimate for Gahcho Kué Diamond Project.

Revised Mineral Resource estimates at 1.0 mm bottom cut-off for the Tuzo, 5034, and Hearne kimberlites are disclosed in this Report.

1.1

Property Setting

The Project is located at the informally-named Kennady Lake, approximately 300 km east-northeast of Yellowknife in the District of Mackenzie, Northwest Territories (NWT), Canada. The property lies on the edge of the continuous permafrost zone in an
area known as the barren lands.  This terrain is characterized by low heath and tundra, with occasional knolls, bedrock outcrops, and localized surface depressions interspersed with lakes. Topographic elevations within the property range
between 400 masl to 450 masl. The climate in the Gahcho Kué area is classified as sub-arctic, as the site is located immediately north of the tree line.  Winters are long and cold, and summers are short and generally cool.  The dominant flora
is scrub birch-Labrador tea tundra and scrub birchcloudberry. Fauna includes red fox, arctic fox, sic sic (small spotted squirrel), grizzly bear, wolf and caribou (during annual migration), ptarmigan, abundant migratory bird life in summer,
and clouds of mosquitoes and black flies during the height of the summer months (mid-June to mid-August).

Access to the Project is via float-equipped airplanes landing on the lake during the ice-free summer season and conventional or ski-equipped airplanes landing on an ice airstrip during the winter. In the shoulder seasons access is either direct
using a helicopter or via a 1,000 foot long airstrip marked out on a relatively flat esker, approximately 26 km north of the Gahcho Kué camp. A helicopter transports people and goods between the esker and camp during these periods. Flight
time from Yellowknife is about 1 hour and 20 minutes by Twin Otter. During the 1999, 2001, 2002, and 2006 winters, a permitted 120 km winter ice road was constructed connecting the Property with the main Tibbit-Contwoyto winter ice road, which
supported shipments of fuel, heavy equipment, and construction materials.

1.2

Tenure and Agreements

The Project falls within four mining leases of 21-year tenure held. The mining leases are 100% owned by De Beers Canada Inc. (De Beers Canada), which holds them on behalf of the GKJV. The participating interest of each of the GKJV parties is
governed by the 2002 joint venture agreement, which is registered against the mineral leases.

Interest in the project is governed by the updated and expanded JV agreement effective 1 January 2002 when De Beers Canada agreed to fund all ongoing exploration, development and other project costs, after earning a 51% interest in the property by
completion of a desktop study on 4 August 2000. MPV had subsequently acquired all the shares of minority partner Camphor Ventures in 2007 and now holds 49% of the property.

Leases are maintained by annual payments to the Department of Indian and Northern Affairs at C$1 per acre, increasing to C$2 per acre upon renewal to a second 21-year term. The total area under the lease is 4,189.72 ha (10,353 acres).

Mining tenure held by De Beers on behalf of the GKJV is valid and sufficient to support Mineral Resources. De Beers has taken appropriate steps to insure extension of the leases, which will remain valid until 15 July 2023 because of expenditures on
the property to date. Surface rights have not yet been acquired, but this is not viewed by AMEC as a significant obstacle to further development of the Project. Those rights can be obtained by application to the Crown.

At this time, all of the permits required for exploration are in force. During those periods when exploration was active, the work was conducted under the appropriate permits.

Permits required for exploitation were identified, and the process for obtaining those permits was defined.

1.3

Previous Work

There is no recorded exploration prior to 1992 for diamonds, base, or precious metals in the area covered by the Property.  Exploration conducted on behalf of MPV by Canamera Geological Ltd. during 1995 resulted in the discovery of the 5034
kimberlite.

De Beers became the operator of the property via a joint-venture agreement in 1997. Additional kimberlites, including Tesla, Hearne, and Tuzo, were discovered the same year.

Inferred and Indicated Mineral Resources were disclosed for the first time using CIM definitions in 2003 with a supporting Technical Report filed on SEDAR (System for Electronic Document Analysis and Retrieval) on July 17, 2003.  Information
contained in the July 2003 Technical Report is superseded by this Report, and should not be relied upon. Since 2003, there have been material changes to scientific and technical information, including additional diamond and geotechnical drilling,
conceptual open pit and underground design work, supplementary metallurgical testing, and optimization studies as discussed in this Report.

1.4

Geology and Mineralization

The Gahcho Kué kimberlite cluster occurs in the southeast Slave Craton.

Several kimberlite bodies were discovered and delineated by drilling. The 5034, Hearne North, Hearne South, and Tuzo pipes have the most attractive grades and tonnages delineated to date. Of the larger kimberlites on the property, the 5034
kimberlite is interpreted as forming an irregular hypabyssal root zone, Hearne and Tesla as transitional diatreme to root zones and Tuzo as the deeper part of a diatreme zone (Tesla is not included in the Gahcho Kué Mineral Resource because
of its small size (0.4 ha) and relatively low-grade).

The 5034, Hearne, and Tuzo kimberlites have contrasting pipe shapes.  The West Lobe, Centre Lobe, and eastern portion of the North-East Lobe of the 5034 kimberlite sub-crop below lake-bottom sediments; the northern portion of the 5034 North-East
Lobe (referred to as the North Lobe) is a blind lobe overlain by approximately 80 m of in-situ country rock. The 5034 pipe is dominantly infilled with hypabyssal kimberlite (HK). Hearne South is a roughly circular pipe and smaller than Hearne North,
which is a narrow elongated pipe. Hearne South is infilled predominantly with tuffisitic kimberlite breccia (TK); Hearne North is infilled with approximately equal amounts of HK and TK. Tuzo is characterized by smooth, steep-sided pipe walls and is
predominantly infilled with TK with HK at depth.

In most cases, the top of the kimberlites occur between 380 and 390 masl. Except for the 5034 North Lobe, which intrudes 70 to 80 m below a peninsula, the kimberlites subcrop at the bottom of Kennady Lake, covered by 10 to 15 m of water and between
5 to 15 m of glacial lake sediments. The kimberlites are surrounded laterally by granite and granite-gneiss country rock.

The geological understanding of the deposit setting, lithologies, and kimberlite type distributions is adequate to support Mineral Resource estimation. Understanding of diamond distributions within each kimberlite type is sufficient to support
Mineral Resource estimation.

The style of mineralization is sufficiently understood to support Mineral Resource estimation.

1.5

Drilling and Sampling

The property was the subject of several drilling campaigns since the initial work by Canamera Geological Ltd. in January 1995. In 1995 small diameter core drilling (47.6 mm NQ core) by Canamera Geological Ltd. discovered the 5034 kimberlite during
drilling of geophysical anomalies at the head of a kimberlitic indicator mineral dispersion train.

Since then small-diameter NQ core drilling was used extensively to test geophysical and kimberlite indicator mineral dispersion-train targets peripheral to the 5034 cluster (Tuzo and Hearne were discovered in 1997), as well as to delineate the shape
of the kimberlite bodies and to provide data (including micro-diamonds) for geological and Mineral Resource modelling.

Large diameter core (LDC) drilling was used to collect small mini-bulk samples from 5034. In 1996 Canamera Geological Ltd. obtained PQ-sized core samples (85 mm diameter), and in 2007 GKJV obtained 149 mm diameter LDC samples.  The LDC samples
provide additional information (macro-diamonds) regarding the diamond content of the pipes.

Large diameter reverse circulation (RC) drilling (LDD) was used to collect kimberlite mini-bulk samples by GKJV.  LDD programs have included smaller scale 140 mm (5.5 -inch) diameter drillholes in 1998 and 1999, 311 mm (12.25 -inch) drill holes in
1999, to the largest employed, the 610 mm (24-inch) diameter drill holes in the 2001, 2002, and 2008 mini-bulk sampling programs. The LDD mini-bulk sample programs were obtained macro-diamonds for grade and revenue estimation.

5034

Canamera Geological Ltds. 1995 and 1996 drilling of the 5034 kimberlite comprised 69 NQ core holes to obtain geological and pipe volume data and 43 PQ core holes to obtain macro-diamonds for a preliminary estimate of diamond grade. An
additional 11 NQ core holes and 17 RC holes of various sizes were drilled by GKJV between 1998 and 2002. Mini-bulk sampling conducted between 1998 and 2002 to determine diamond grade and revenue has included 140 mm (5.5 -inch) diameter drill holes
in 1998, 311 mm (12.25 -inch) diameter drill holes in 1999, and 610 mm (24-inch) diameter holes that were drilled in 2001 and 2002. The 1998 and 1999 drilling focused on the 5034 West, Centre and East lobes; in 2001 the East Lobe and the west neck
of the Centre Lobe were drilled; in 2002 work focused on the narrow corridor drilled previously in 1999 through the West and Centre lobes. There was one delineation NQ core hole drilled by GKJV at 5034 in 2003.

In 2004, 13 core holes drilled into the 5034 kimberlite as part of pit geotechnical, hydrogeology, and ore dressing studies (ODS). In 2005, a single core hole for hydrogeology studies drilled through the East Lobe of 5034, and two core holes were
drilled at the North Lobe of 5034 to provide additional geological data.  A substantial core program followed this in 2006 that comprised 11 HQ core holes for pit geotechnical, pipe volume delineation, and geological investigations.  The last
campaign of core drilling was conducted in 2007 with five HQ core holes being drilled to provide geological data from the 5034 East Lobe and 5 LDC holes (149 mm, 5.875 -inch) drilled into the 5034 North Lobe to obtain a small parcel of
macro-diamonds for comparative purposes.

Hearne

A total of 25 core holes were drilled in and around the Hearne kimberlite by GKJV during 1997-2003:

- 17 in Hearne North
- 6 in Hearne South (1 that intersected both pipes)
- 2 of which did not intersect kimberlite.

| | ------------------------------------------------------------------------------------------------------------------



In 1998, 19 LDD holes (140 mm diameter) were drilled into the Hearne kimberlite to test the diamond grade:

- 16 were located at Hearne North
- 1 in Hearne South
- 2 holes intersected only granite.

In 1999, 8 LDD (311 mm diameter) holes were drilled into Hearne North and 2 into Hearne South to obtain macro-diamonds for initial revenue estimation.  In 2001, 3 LDD (610 mm diameter) holes were drilled into the northern half of Hearne North, and 5
more LDD (610 mm diameter) holes tested Hearne North in 2002, to increase the parcel of macro-diamonds available for revenue estimation.

In 2004, 14 NQ core holes were drilled into the Hearne kimberlite as part of pit geotechnical and ODS programs. In 2005 a single core hole was drilled for hydrogeological studies, and in 2006 a single core hole was drilled to support pit
geotechnical studies.

Tuzo

Between 1997 and 1999, 8 NQ core holes were drilled into Tuzo. All of these were angle holes collared outside the kimberlite body and drilled into, and sometimes through, the kimberlite. In 2002, 7 vertical HQ core holes were drilled into the pipe.
LDD mini-bulk sample drilling took place in 1998 and 1999.  Drilling to a maximum depth of 166 m, 17 LDD holes (140 mm diameter) were completed in 1998, and an additional 11 LDD holes (311 mm diameter) were completed in 1999 to a maximum depth of
300 m.

In 2004, 2 HQ core holes were drilled at Tuzo as part of a pit geotechnical study. This was followed by an 11-hole HQ core program in 2006 to provide pipe delineation and geological data. In 2007, a grid of 27 HQ core holes was completed to provide
additional geological and pipe volume delineation data. The final resource drilling at Tuzo was an LDD mini-bulk sample program conducted in 2008 with 9 holes (610 mm) completed to provide additional macro-diamonds for diamond revenue estimation.

Comments

Exploration programs completed to date are appropriate to the style of mineralization and adequate to support Mineral Resource estimation.  Drill hole types and orientations are appropriate for the type of mineralization. Small-diameter core holes
defined the limits of the kimberlite bodies.  Large-diameter core and reverse circulation drilling provided mini-bulk samples of kimberlite material for macro-diamond extraction. Micro-diamonds extracted from the small-diameter cores drilled to
define the limits of the deposit. Three diamond breakage studies indicate that breakage was about 1015% that is typical for this type of drilling program. The diamond parcels obtained in 20072008 were not evaluated for diamond breakage.

Sampling and sample lengths are appropriate for the type of mineralization.  Core sample lengths were somewhat variable during the early years of the project. Later in the project, core sample lengths were standardized at 12 m. These standardized
samples provide most of the data used for the Mineral Resource estimates reported here.

Core and cuttings logging meets and typically significantly exceeds industry practices. Core is quick-logged on site, and the kimberlite intersections are transported to De Beers core logging facility in Sudbury, Ontario where experienced
geologists log kimberlite type, mineral and inclusion types and concentrations, and structures. Geotechnical work to date is appropriate for the stage of the project and type of mining planned. Geotechnical logging of exploration core is a routine
procedure performed by geologists trained in the logging methods required. A number of core holes were drilled specifically to obtain geotechnical data. Collar and downhole surveys were performed using industry-standard methods and instruments.

Analytical and diamond recovery procedures are adequate to support Mineral Resource estimation. Macro-diamond and micro-diamond extractions were performed using procedures standard to the industry. Micro-diamonds were recovered from core using
either caustic fusion or acid dissolution procedures. Both are standard to the industry, although caustic fusion is the most common procedure. Macro-diamonds are extracted using small-scale diamond recovery plants. Geochemical samples were analyzed
using standard procedures and instrumentation. Density determinations were performed using standard procedures, and the number of density data is adequate to support Mineral Resource estimation.  Most of the density data were obtained using a water
immersion procedure standard to the industry. Some of the data were obtained using geophysical methods, and some were obtained by water displacement methods.  Quality control during drilling, sampling, and sample analysis is adequate and reflects
industry best practices. Quality control of diamond extractions consists of spikes using marked diamonds and tailings audits of a portion of the samples.

Sample and diamond security throughout the exploration process is excellent and consists of rigorous chain-of-custody procedures, multiple locks requiring at least two persons to open critical areas or containers, cameras in all plants and
processing areas, and dedicated security personnel at all plants and processing areas. Shipping of diamonds and diamond concentrates conforms to requirements of Kimberley Process chain-of-custody procedures.

1.6

Data Verification

Independent data verifications were undertaken on a number of occasions between 1999 and 2008:

- 1999, 2004, 2007  independent consultants made site visits to review quality assurance/quality control (QA/QC)
- 1999  external consultant audit of the 1999 evaluation program
- 2000  geology (petrological) peer review

| | ------------------------------------------------------------------------------------------------------------------



- 2004  geotechnical and hydrogeology consultants QA/QC site visit, internal and external Mineral Resource evaluation data base audits, geology (petrological) peer review, Gemcom®three-dimensional (3D) model peer review
- 2007  internal and external petrological peer reviews; external verification of macro-diamond resource evaluation data set
- 2008  external review of 2003 Technical Report resource estimation and density (rock density) models.

Resource evaluation data base verification included:

- audits of drill collar locations and lengths
- down-hole survey data
- geological logs
- bulk density data
- macro-diamond data.

Data storage and verification procedures are adequate to support the geological interpretations and thus Mineral Resource estimation.  Data are stored digitally using appropriate database management software (Microsoft Access®), are
being migrated into a diamond sampling workflow-based repository running on a SQL server located in Toronto, and are backed up periodically to insure against loss of data due to failure of a single computer or hard drive. Original data are properly
stored as paper and/or digital files with appropriate backups. Most paper files were scanned and are stored digitally. The project database undergoes periodic internal verification as well as periodic audits by external reviewers.

1.7

Metallurgical Testwork

Metallurgical testwork is appropriate for the stage of the project and is adequate to support Mineral Resource estimation.  Mini-bulk samples were processed using scaled-down equipment that allows collection of some of the processing parameters.
Other parameters were obtained from core specifically drilled for that purpose.

1.8

Mineral Resource Statement

Large diameter reverse-flood drilling (LDD) provided samples of kimberlite for grade and diamond value modelling. Macro-diamonds from the LDD were used to estimate local grades on 5034 West and Centre Lobes and Hearne Pipe. Grade estimations for
these pipes were completed using variography and kriging methods. Diamonds from this drilling were also used to confirm diamond size and value data for all lobes and pipes.

Micro-diamonds from drill core were used to create local estimates of grade for the 5034 NorthEast Lobe and Tuzo Pipe. Micro-diamonds are stones (less than 0.5 mm) recovered from the
dissolution of drill core using a caustic fusion process.  These results were kriged into local blocks (25 m x 25 m x 12 m) and then converted to carats per hundred tonnes above a commercial bottom cut-off using a model of grade with size developed
from micro and macro diamonds.

| | ------------------------------------------------------------------------------------------------------------------



Density modelling was completed using dry densities.  Density was estimated per Lobe for 5034 West and Centre, locally into mining blocks for the 5034 North-East Lobe and Tuzo, and by rock type for Hearne Pipe.

Industry-standard techniques were used to ensure appropriate calculation and reporting of the diamond resources at a +1 mm lower cut-off. The Mineral Resources were adjusted for the expected main treatment plant response by reducing recoveries in
the lower size classes.

AMEC had access to two sources of diamond valuations. One valuation was from the Diamond Trading Company (DTC).  WWW Diamond Consultants International (WWW) performed the second for MPV.

In this Report, AMEC has relied on both valuations and the QPs believe that it is appropriate to rely on both sources.  WWW are recognized international leaders in this field and are the valuers to the Federal Government of Canada for the Canadian
diamond mines in the Northwest Territories.  The DTC is the internal qualified group that performs valuations for DeBeers operations, the recognized originator of the methods in use by all valuators, and the rough diamond distribution arm of the De
Beers Family of Companies. In addition they are the world's largest supplier of rough diamonds, handling nearly half of the world's supply by value.

To assess reasonable prospects for economic extraction to support declaration of a Mineral Resource, diamond valuations from the De Beers Group (project operator) and WWW were analysed, and average mid-2008 pricing with a 20% increase was applied to
the resource blocks. It is common practice in the industry to assume a higher long-term commodity price when determining a cut-off grade for Mineral Resources than the long-term commodity price used for mineral reserves or financial analysis.

Most of the Mineral Resources were shown to be amenable to open-pit mining. The relatively small amount of remaining material lying outside of the resource pit shell was, at least conceptually, shown to have reasonable prospects of economic
extraction using underground mining methods.  Further study is required to determine economic viability of the material amenable to underground mining methods. Average diamond pricing was only used to assess reasonable prospects of economic
extraction to support declaration of Mineral Resources.

Table 1-1 summarizes the Mineral Resource estimate. The Qualified Person for the estimate is Ken Brisebois, P.Eng., an AMEC employee.  In this case, AMEC has elected to report the resources at a zero cut-off grade, deeming that the kimberlite
contacts can be considered to be the potentially mineable boundaries. AMEC cautions that Mineral Resources are not Mineral Reserves and do not have demonstrated economic viability.

Recommendations

The scientific and technical data on the Gahcho Kué project is
of sufficient quality and level of detail to support a feasibility study, if a
decision is made by the GKJV to proceed to a feasibility study. AMEC recommends
that the GKJV monitor market conditions to determine when such a decision would
be appropriate.

RELIANCE ON OTHER EXPERTS

The QPs, authors of this Report, state that they are Qualified Persons for those areas as identified in the appropriate QP Certificate of Qualified Person attached to this Report. The authors have relied upon information derived from the
following reports pertaining to mineral rights, surface rights, and permitting issues.

3.1

Mineral Tenure

AMEC QPs have not independently verified the legal status or ownership of the Project area, the mineral tenure, or underlying property agreements.  AMEC has relied upon internal company documents from De Beers Canada for information on the mineral
tenure, surface rights, and property agreements in Section 4.3 and 4.4 of the Report as follows:

- De Beers, 2009: Gahcho Kue Leases: unpublished Excel®spreadsheet mineral tenure summary
- De Beers, 2009: Database and Drill Core Review, Tenure and Report List: unpublished email series to AMEC, dated 5 January, 2009.

The portion of Section 4.4 of this Report that pertains to the 2002 joint venture agreement was reviewed by Faskin Martineau, Barristers and Solicitors, legal counsel to De Beers Canada and was found to accurately reflect the participating interests
of the joint venture partners as of the effective date of this Report (20 April 2009).

3.2

Diamond Valuations

AMEC has relied on WWW International Diamond Consultants (WWW) for diamond valuation. WWW are recognized international leaders in this field, and are the valuers to the Federal Government of Canada for the Canadian diamond mines in the Northwest
Territories.  This information was used in support of Section 17 through the following document:

- WWW International Diamond Consultants Ltd., 2008: Valuation of Diamonds from the Gahcho Kue Diamond Project, September 2008, unpublished report prepared for Mountain Province Diamond Inc., November 14, 2008.

AMEC has also relied on De Beers for diamond valuation in support of Section 17 through the following documents:

- Ferreira, J.J. (2008): Mineral Resource Estimation for Gahcho Kué 5034 North And East Lobes. De Beers Canada Inc.
- Ferreira, J.J. (2009): Mineral Resource Assessment Based on Micro-diamond sampling for the Tuzo Kimberlite, Gahcho Kué. De Beers Canada Inc.

ProjectNI 43-101 Technical ReportNorthwest Territories, Canada
| | ------------------------------------------------------------------------------------------------------------------



The QPs believe it is appropriate to rely on De Beers valuations, as The Diamond Trading Company is the rough diamond distribution arm of the De Beers Family of Companies and is the world's largest supplier of rough diamonds, handling nearly half of
the world's supply by value.

3.3

Diamond Modelling and Prices

AMEC has relied on Mr. Martinus Oosterveld for comparison of the De Beers and WWW diamond valuations, and for modelling of the diamonds and their distribution in support of Section 17 through the following document:

- Oosterveld, M., 2009 (for AMEC): Comparison of De Beers and WWW International Diamond Valuations, unpublished memorandum, November 14, 2008.

|4.0 | PROPERTY DESCRIPTION AND LOCATION
|--- | ---------------------------------
|    |                                  
|4.1 | Location                         

The Gahcho Kué Project is located at the informally-named Kennady Lake, approximately 300 km east-northeast of Yellowknife in the District of Mackenzie, Northwest Territories, Canada, at the approximate latitude 63.26.16N and longitude
109.12.05W (NAD83 Zone 12 coordinates 7035620N, 589735E.

The Project is located 150 km southsoutheast of the Diavik and Ekati diamond mines operated by Dia Met Minerals Ltd. and BHP Diamonds Inc. at Lac de Gras, and 80 km eastsoutheast of the De Beers Snap Lake mine.

The Gahcho Kué Project consists Hearne North and South; 5034 West, Central and NorthEast; 5034 South Pipe; 5034 North Pipe; Wallace; Dunn Sheet and Tesla diamondiferous kimberlite pipes, sheets and dykes.  Except for the northernmost part of
5034, the main kimberlite pipes all lie beneath Kennady Lake.  Only the 5034, Hearne, and Tuzo pipes are adequately explored to allow estimation of Mineral Resources. A number of other kimberlite occurrences including Dunn Sheet and Wallace were
explored, but currently have insufficient data to support Mineral Resource estimation.

4.2

Tenure History

The Gahcho Kué Project was part of a larger group of mining claims, known as the AK Property, which currently consists of four remaining mining leases (Figure 4-1 and Table 4-1). The AK Property was initially staked in 1992 by Inukshuk
Capital Corp., and optioned to Mountain Province Mining, Inc. (now Mountain Province Diamonds, Inc  MPV) later the same year.

On staking, the project covered about 520,000 ha, and included the AK and CJ claims. The CJ claims substantially lapsed in November 2001, and the remaining CJ claims lapsed on August 17, 2002, leaving only the AK claims as current.

Additional partners in the AK Property included Camphor Ventures Inc. (Camphor Ventures), and 444965 B.C. Ltd, a subsidiary company of Glenmore Highlands Inc. (Glenmore Highlands). At the time, Glenmore Highlands was a controlling shareholder of
Mountain Province Mining Inc. as defined under the Securities Act of British Columbia.  The Glenmore Highlands subsidiary amalgamated with MPV in 1997, and Camphor Ventures interest in the AK Property was acquired by MPV during 2007.

In 1997, Monopros (now De Beers Canada) joint ventured the property.  The currently applicable agreements between the partners are summarized in Section 4.4.

4.3

Mineral Tenure

The Gahcho Kué Project comprises four mining leases, 4199, 4341, 4200, and 4201, covering a total area of 10,353 hectares (Figure 4-1 and Table 4-1). The mining leases are 100% owned by De Beers Canada Inc. who holds them on behalf of the
GKJV. The participating interest of each of the GK joint venture parties is governed by the 2002 joint venture agreement, which is registered against the mineral leases (see Section 4.4) .

Annual lease payments, payable to the Receiver General Canada (Northwest Territories, c/o Mining Recorders Office), comprise $1.00 per acre for the duration of the 21-year lease period (note that fees are payable on acres, not hectares, in the
NWT and Nunavut).  Payments increase to $2.00 per acre if a second 21-year term is granted after application to the Northwest Territories Mining Recorder for the extension.  Payments for the leases for 2007 totalled $10,353, and a similar
amount is expected for each succeeding year.

All mining leases were legally surveyed by licensed surveyors.

AMEC has reviewed lease documents provided, at cost, by the Northwest Territories Mining Recorders office. Those documents indicate that all of the leases are valid at the effective date of this report and that the expiry dates for the leases are as
presented in Table 4-1. AMEC concludes that the leases are valid until the expiry dates in Table 4-1.

Immediately to the south, and continguous with the Project mining leases are three sliver claims, mining leases 4732, 4730 and 4731 (Figure 4-1).  The leases have a total area of 11.52 acres, and are held in the names of De Beers Canada
Inc. (55.5%), Mountain Province Diamonds Inc. (24.5%) and GGL Diamond Corp. (20%).

4.4

Agreements

The Monopros Ltd. Joint Venture Agreement, dated 6 March 1997, was entered into between Monopros Ltd. (Monopros; a wholly-owned Canadian subsidiary of De Beers Consolidated Mines and now known as De Beers Canada Inc.), MPV, and Camphor Ventures. The
parties amended the Monopros Ltd. Joint Venture Agreement in 2000, as a result of agreements reached at a meeting on 8 March 2000.

An updated and expanded JV Agreement between De Beers and MPV became effective on 1 January 2002, was signed 24 October 2002, and is still current. This agreement provides that De Beers Canada could earn up to a 55% interest in the project by
funding and completing a positive definitive feasibility study. The agreement also provides that De Beers Canada could earn up to a 60% interest in the project by funding development and construction of a commercial-scale mine.

MPV acquired Camphor Ventures interest in the joint venture in 2007.

Surface Rights

Crown lands are lands owned by the federal or provincial governments. Authority for control of these public lands rests with the Crown, hence their name. Crown land and Commissioners land are both types of public lands. The Federal Government
manages and administers Crown land in Canada.  In the Northwest Territories, Indian and Northern Affairs Canada (INAC) is responsible for the majority of Crown land. Commissioners land is managed and administered by the Government of the
Northwest Territories, and specifically, by the Department of Municipal and Community Affairs (MACA).

Administration of Crown lands, including minerals for the Northwest Territories and Nunavut, is based on the Territorial Lands Act (TLA) and its regulations. The Regulations under the TLA that deal with mineral tenure, leasing and royalties are the
Northwest Territories and Nunavut Mining Regulations (NTNMRs), formerly known as the Canada Mining Regulations (CMRs). Under the current NTNMRs, a party may prospect for minerals and stake mineral claims on any Crown lands covered under the TLA,
including lands in and around the area of the Mackenzie Valley.

A surface lease is required under the Territorial Lands Act if a project will require the use of Crown land anywhere in the NWT for longer than two years. A surface lease does not convey ownership to the minerals on or under the leased property.
Those minerals require a mineral lease (refer to Section 4.3) . The first step to acquire a surface lease is to submit an application for use of Crown land.  For activities taking place in the Mackenzie Valley on Crown land, applications are made to
the Mackenzie Valley Land and Water Board. The Mackenzie Valley, as defined in the Mackenzie Valley Resource Management Act, includes all of the Northwest Territories, with the exception of the Inuvialuit Settlement Region and the Wood Buffalo
National Park.

The Gahcho Kué Project is operated under a Class A Land Use Permit (permit number MV2008C0022, expiry date 22 April 2014) and a Class B Water License (permit number MV2003L2-0005, expiry date 22 April 2014).

Surface rights for construction of a diamond mine, including plant, access roads, airstrip, and accommodation have not been granted.  Development of such infrastructure will require the approval of a submitted Environmental Impact Review (EIR),
discussed in Section 4.7 of this Report.

The MVEIRB initiated the EA on 4 January 2006. On 12 June 2006,
the MVEIRB concluded that the proposed Project would likely cause significant
public concern and ordered that the GKJV conduct an Environmental Impact Review
(EIR) for the proposed development pursuant to the Act. The MVEIRB issued its
Reasons for Decision and Report of Environmental Assessment for the De Beers Gahcho Kué Diamond Mine, Kennady Lake, NWT on 28 June 2006.

On 28 July 2006, GKJV requested that the NWT Supreme Court
conduct a judicial review on the MVEIRBs decision. The Supreme Court heard the
application on 22 November 2006 and upheld the MVEIRBs decision for an EIR
process on 2 April 2007. The MVEIRB notified potential parties and the public of
the continuation of the EIR process on 20 April 2007.

In May 2007, the MVEIRB released the draft Terms of Reference
for the Environmental Impact Statement (EIS) and appointed the Gahcho Kué
Environmental Impact Review Panel (the



|Project No.: 161325 May 2009 | Page 4-9 |

| | ------------------------------------------------------------------------------------------------------------------



Gahcho Kué Panel).
The Gahcho Kué Panel is an independent body consisting of seven members. It is responsible for assessing the potential impacts of the proposed Project. A final Terms of Reference for the EIS was released on 5
October 2007.

EIS preparation is currently on hold, and may be filed during the latter part of 2009. When the GKVJ files the EIS, the Gahcho Kué Panel will assess the proposed Project using the EIS and other relevant information. The Gahcho Kué
Panel will conduct a conformity check of the EIS to determine if the Terms of Reference were met. It will then initiate a technical review; issue and process information requests; review the public registry; conduct technical and public hearings if
necessary; and prepare a Report of the Gahcho Kué Panel.

The Gahcho Kué Panels report will make a recommendation whether the Minister of Indian and Northern Affairs should approve the proposed development and if so under what conditions (with or without mitigation or remedial measures or a
follow up program) or whether the proposed development should be rejected. The Minister will then distribute the Gahcho Kué Panels report to every responsible minister for consideration.  Upon consideration, the ministers may issue a
decision on whether the proposed development will proceed to permitting, and if so, under what conditions.

Should the Gahcho Kué Panel recommend approval at the completion of the environmental impact review process, the Project will enter a second licensing phase. GKJV will then make applications for the many licenses, permits, and authorizations
that fall under federal and territorial jurisdictions (see Table 4-2). The Project will require permits for long-term land tenure through a land lease.  GKJV will return to the MVLWB to re-activate the application for the Class A Land
Use Permit and the Class A Water License.

4.7.3

Rehabilitation

GKJV estimates that rehabilitation costs associated with dismantling the current camp infrastructure, remediation of waste and drill cutting containment bunds, and areas that were subject to exploration and drilling programs, are approximately
$12 M.

The Gahcho Kué Project occurs at the informally-named Kennady Lake (NTS map sheet 75N/6), 20 km north of tree line with no permanent road access. Access to the Project is by float-equipped planes during summer months and ski- or
wheel-equipped planes in winter. During winter, larger aircraft such as the Dash-7 and Super Hercules L100 Transport can operate from an artificially-thickened ice landing strip on Kennady Lake.

Helicopter pads are located within the base camp to support drilling and logistical operations. During the short shoulder seasons, access to the property is via a 1,000 ft long runway established on an esker at Kirk Lake Camp located
approximately 26 km north of Gahcho Kué; Passengers and supplies are transferred to the site by helicopter.

During winter, a permitted 120 km winter ice road connecting the Project with the main Tibbit Lake to Contwoyto Lake winter road is built, if required, by Nuna Logistics. The winter ice road supports shipment of fuel, heavy equipment, construction
materials and bulk samples.  The main winter ice road connects Yellowknife to the Lupin, Ekati, and Diavik mines from February to April each year to the extent that weather allows. The road is operated under a Licence of Occupation by the Joint
Venture Partners who operate the Ekati and Diavik mines.

5.2

Climate

As the Gahcho Kué Project is located 230 km south of the Arctic Circle, the climate is extreme and semi-arid. Temperatures range from -45°C to +25°C over a twelve-month period. Winter normally lasts from November to May and has
average temperatures of about -20°C. Summer temperatures prevail from early July to mid-September, and average about 18°C. Freeze-up and ice break-up occur in November and June, respectively.  Table 5-1 summarizes key climate data reported
from site. Activities are possible on-site year-round.

Daylight hours range from near zero in mid winter (Winter Solstice) to effectively 24 hours (Summer Solstice). The spring and fall equinox occur in March and September respectively, marking the period when length of daylight and darkness are
equal.

      Kennady Lake near the southeast edge of the postulated future limits of
      the 5034 pit. Living quarters are a mixture of four-person soft-shell
      cabins and skid-mounted dorm units, clustered with other detached
      buildings, including kitchen and dining room; recreation building; office
      building; core storage; mens and womens dry; waterless toilet system;
      fuel storage; shops; and warehouses. The camp is currently on
      care-and-maintenance.

The Gahcho Kué project lies on the edge of the continuous permafrost zone in an area known as the barren lands, which are characterized by heath and tundra, with occasional knolls, bedrock outcrops, and localized surface
depressions interspersed with lakes.

Thin, discontinuous covers of organic and mineral soil and glacial till deposits overlie bedrock, which occurs typically within a few metres of surface. Some small stands of stunted spruce occur in the area.

There are myriad lakes in the area. Kennady Lake, under which the kimberlite pipes lie, is a local headwater lake with a minimal catchment area, very pure water, and relatively low potential for aquatic life.

Flora and Fauna

Baseline studies of fisheries and aquatic resources of the Gahcho Kué/Kennady Lake area were conducted between 1996 and 2007.  These included bathymetric surveys, shoreline, shoal, and tributary habitat assessments, sediment toxicity
sampling, and limnology surveys, as well as studies to characterize the periphyton, phytoplankton, zooplankton, benthic invertebrates, and fish communities in the Kennady Lake area.

Systematic wildlife field studies were conducted for the Gahcho Kué project from 1999 to 2007. Habitat in the Gahcho Kué area represents a transition between the taiga coniferous forest and the treeless landscape of the tundra. Fauna
includes red fox, arctic fox, sic sic, grizzly bear, wolf and caribou (during annual migration), ptarmigan, abundant migratory bird life in summer, and clouds of mosquitoes and black flies during the height of the summer months (mid-June to
mid-August).

Vegetation in the area is characteristic of low arctic tundra. Shrubs of willow
and birch occur in drainages, and in some areas may reach over 2 m in height.
Heath tundra covers most upland

areas. Conifer stands occur in patchy distribution north of the tree line in
lowland, sheltered areas, and riparian habitats, and are found as far north as
Kirk Lake.

5.6

Seismicity

A seismic hazard evaluation of the Project area was performed to determine the potential effects of seismic loading on the dykes and plant facilities. No major earthquake is known to have occurred in the past century in the vicinity of the Project.
The largest in magnitude, and the closest-known earthquake event, occurred more than 1,000 km west of the site. There was no significant seismic activity recorded within 500 km radius of the site.

HISTORY

There is no recorded exploration prior to 1992 for diamonds, base or precious metals in the area covered by the AK Property claims.

Inukshuk Capital Corp. (Inukshuk) staked the property in 1992, and Mountain Province Mining Inc. (MPV) joint ventured into the area later that year. Exploration by Mountain Province Mining Inc., as operator, and Canamera Geological Ltd. (Canamera),
during 19921993 consisted of an airborne geophysical survey and sediment sampling. The 5034 kimberlite was discovered in 1995 in the southern portion of the AK Property.

In 1997, following a due diligence assessment, Monopros Ltd. (now De Beers Canada Inc.) entered into a joint venture in the project. Three additional kimberlites were discovered during the 1997 exploration period: Tesla in May 1997 and Tuzo and
Hearne in August 1997. Tesla, Tuzo, Hearne, and 5034 form the main Gahcho Kué kimberlite cluster. The Kelvin and Faraday kimberlites, located about 7 km to 12 km northeast of the Gahcho Kué cluster, and the Dunn Sheet anomaly, 250 m
west of the 5034 and Tuzo kimberlites, and Wallace, 200 m south of 5034, were subsequently identified and outlined as a series of narrow kimberlite dykes and stringers.

Exploration and development work undertaken during 19972008 has included:

- sediment sampling, including glacial till, sediment and outcrop sampling
- geological mapping
- airborne electromagnetic (EM) and ground geophysical surveys
- core drilling, including large diameter core mini-bulk sampling
- reverse circulation drilling, including mini-bulk and bulk sampling programs utilizing reverse- flood air-lift assist large diameter drill rigs
- geotechnical, hydrogeology and civil engineering drilling
- micro- and macro-diamond sample processing and analysis
- diamond valuation and diamond breakage analysis
- bulk density determinations
- ore dressing studies
- construction of geological and micro-diamond grade models and Mineral Resource block models
- construction of density, geotechnical, and volume models
- conceptual mine plans
- conceptual process plant design.

A first-time Mineral Resource estimate was completed in 2003 to support a conceptual desktop study of the potential of these pipes.  The study included Inferred Mineral Resources, considered too speculative geologically to have economic
considerations applied to them. The study evaluated a conceptual open pit mining operation, using conventional truck and shovel equipment. A diamond recovery plant with a diamond recovery efficiency of not less than 98% by weight of free diamonds
larger than the bottom cut-off size of 1.5 mm was designed, using established De Beers diamond value management principles. The study indicated that the net present value and internal rate of return were likely to be positive and supported
continuing exploration and evaluation work.

Information in this Report supersedes the 2003 Technical Report. The new information is a combination of additional diamond and geotechnical drilling completed since 2003, conceptual open pit and underground design work, supplementary
metallurgical testing and optimization studies.

From 2003 to 2008, a number of additional desktop studies were completed that consider aspects of conceptual mining studies.  These have comprised conceptual mining and processing considerations, evaluation of different potential input factors and
assumptions, and alternatives to and variations and iterations within such plans, including:

- changes to Mineral Resource estimation methodologies and strategies
- changes to dilution and reconciliation strategies
- changes to diamond prices
- changes in allocations of planned drilling, or drilling locations
- changes to deposit sequencing
- changes to production rates
- changes in mining equipment strategies
- alternate pit configurations, including laybacks or pit wall slope changes
- changes to geotechnical or hydrological assumptions
- changes in short-term production
- proposed mill design throughput reviews and potential mill modifications
- process flowsheet development and flowsheet modifications
- stockpile throughput, allocations, and planned depletion rates
- review of different cash flow scenarios
- changes to allocations of capital expenditures to different years within conceptual mine plans
- modifications to sustaining capital and operating cost assumptions within conceptual mine plans

|7.1 | Regional Geology  

The Gahcho Kué kimberlite cluster occurs in the southeast Slave Craton, a small Achaean nucleus within the North American Craton (Figure 7-1), which contains rocks ranging in age from 4.05 Ga to 2.55 Ga (Bleeker et al., 1999). The oldest
rocks of the Slave Craton are small remnants of felsic granites and gneisses (2.8 Ga to 3.2 Ga; Beals, 1994), and the Acasta Gneisses (3.6 to 4.0 Ga; Bowring et al., 1989) located in the western part of the craton. Several supracrustal series
(metasedimentary rocks with less common metavolcanic rocks) crop out in the central and eastern parts of the Slave Craton, forming the Yellowknife Supergroup (circa 2.7 Ga). The Yellowknife Supergroup is intruded by an extensive series of pre- to
post-deformational (2.69 to 2.60 Ga) felsic plutons.

The eastern portions of the Slave Craton are Late Achaean island-arc complexes (magmatic arcs and accretionary prisms) accreted to the margin of an older continental fragment to the west (Griffin et al., 1999).

Several swarms of Early-Mid Proterozoic (2.0 -2.3 Ga; see LeCheminant et al., 1995) basaltic dykes occur in the Lac de Gras area. A suggest source for the Lac de Gras dyke swarm is beneath the Kilohigok Basin. The northnorthwest trending
Mackenzie dyke swarm (1.27 Ga; LeCheminant and Heaman, 1989) extends over 2,300 km from a focus, interpreted as a plume head (Fahrig, 1987), and located west of Victoria Island.

The kimberlite intrusions are of Cambrian age (approximately 540 Ma).

|      | Basement lithologies mapped from limited areas of outcrop in a 16 km2area surrounding the Gahcho Kué cluster include granite, granitic gneiss, minor granodiorite, and diorite that have undergone regional
amphibolite-facies metamorphism retrograded to greenschist facies (Baker, 1998). The most common rock type, granite, varies from a medium-coarse grained, equigranular facies to highly foliated granitic gneiss.

|      | Two distinct northwest to northnorthwest-trending, linear, magnetic highs in the eastern quadrant are interpreted to be part of the regional Mackenzie diabase dyke swarm. Two east northeast-trending diabase dykes were
identified from linear aerial photo-features occurring south of Kennady Lake and proximal to the Tesla kimberlite. These dykes can be traced in outcrop but do not have strong magnetic expression. They are considered to belong to the Mallay dyke
swarm by Baker (1998) and to predate the interpreted Mackenzie dykes.

|      | The Gahcho Kué area was glaciated repeatedly during the Pleistocene Epoch, most recently by the Laurentian ice sheet. The Laurentian ice sheet began to recede 18,000 years ago, and the ice front retreated past the Gahcho
Kué project area between 9,000 and 9,500 years ago (Dyke and Prest, 1987). However, there is no stratigraphic evidence that represents deposits from previous glaciations; the Quaternary geology of the Gahcho Kué area appears to be
related only to the last glacial event, the Wisconsinian glaciation (Hardy, 1997). Glacial-related sedimentation is quite thin, with only scarce patches of till blanket and large fluvioglacial outwash fans (Hardy, 1997).

|      | Till veneer, till blanket, and outwash sediments characterize the Quaternary deposits in the Gahcho Kué area. The areas of till blanket contain abundant mud boils and no bedrock exposure. Areas of level sands and reworked
till are classified as outwash sediments. Till veneer and till blanket cover most of the area except for small areas to the east of the campsite; outwash sediments occur west of Kennady Lake. Outwash sediments and a large esker that extends along a
portion of the southern edge of the mapped area dominate the area south of Kennady Lake.

|      | The stratigraphic record overlying the till is younger than the last glaciation and is composed mainly of pro-glacial sediments (glaciofluvial and glaciolacustrine deposits). As the Gahcho Kué area occurs over a relatively
flat terrain, many swamps, ponds, and peat deposits are present (Hardy, 1997).

|      | Granitegneiss terrane intruded by a series of dykes (Figure 7-2) characterizes the Gahcho Kué area. There are several granitic intrusions surrounded predominantly by gneisses; the gneisses display a clear structural
pattern of being metamorphosed by the granitic intrusions. Along the eastern edge of the area, a marked geological boundary is interpreted to represent contact with meta-sediments that extend eastwards. The central portion is a structurally complex
zone of folding and possible shears.

There are several groups of demagnetized lineaments with weak, negative magnetic expression; these demagnetized lineaments could be dykes or demagnetized country rock resulting from dyke intrusion or faulting. They are grouped as:

- a regular, pervasive northeast-trending set
- a regular, pervasive northwest-trending set
- an eastwest-trending set in the south of the area.

The 5034, Hearne, Tuzo, and Tesla kimberlites all occur at the eastern edge of
an interpreted south-closing fold-nose that has developed a radial fold-nose
cleavage. The apparent south-closing

fold is interpreted to open to the
northnortheast; the dip direction is not known. The core of the fold is
composed of granite and minor granodiorite. Northeast-trending axial-planar foliation associated with the
fold is developed in gneiss.

|      | Tuffisitic kimberlite (TK) is olive green to light brown in colour. These rocks are relatively soft and can swell on contact with water because of the presence of hygroscopic clay minerals. The TK drill cores are characterized by
matrix-supported magmaclastic breccia textures. Common fresh, typically pink-coloured, granitoid xenoliths vary in abundance from 30% to 95% and are as large as 5 m. Xenocrysts of country rock are common and are often shard-like in shape. TK
contains two generations of olivine present as macrocrysts and phenocrysts, which are completely pseudomorphed by serpentine. Pelletal lapilli are common; these typically consist of thin selvages of kimberlite, which rim most of the olivines,
xenoliths and xenocrysts. Altered groundmass minerals can be identified within the selvages. The matrix between the pelletal lapilli consists of common serpentine and clays. Primary carbonate is not present. In thin section, microlites, which
include clinopyroxene, are common. Mantle xenoliths are extremely difficult to identify within the core due to alteration.

|      | Rocks classified as transitional tuffisitic kimberlite (TKt) are broadly similar to TK but are more competent and darker in colour. The TKt rocks have a uniform olivine distribution but the breccia matrix displays inhomogeneous
textures dominated by magmaclastic textures or pelletal lapilli. In thin section, clinopyroxene microlites are present; however, they are slightly coarser grained than those within the TK rocks. These TK-like areas are closely intermixed with less
common small patches that possess magmatic textures. Country-rock xenoliths are less common in TKt than in TK and show greater reaction to the host kimberlite. Xenoliths often have a green colour and are more difficult to distinguish within the
kimberlite matrix. Olivine macrocrysts and phenocrysts are completely altered to serpentine.

|      | Rocks classified as transitional hypabyssal kimberlite (HKt) are broadly similar to the HK rocks but are characterized by inhomogeneous textures dominated by a magmatic groundmass with less common patches of magmaclastic
kimberlite. These rocks are dark in colour and competent. The granitoid xenoliths show a degree of reaction with the host kimberlite that is intermediate between HK and TKt and are typically dark green to black in colour. Olivine macrocrysts and
phenocrysts are completely pseudomorphed by serpentine. Groundmass minerals include phlogopite, spinel, carbonate, serpentine and perovskite.

clinopyroxene is common within the groundmass and is much coarser grained than
the microlites present within TK and TKt rocks. Such clinopyroxene is absent
within HK.

|      | Hypabyssal kimberlite (HK) is mainly fresh, competent, black to dark green, and characterized by uniform macrocrystic textures. The rocks are composed of two generations of olivine consisting of anhedral, medium-grained, often
fresh, olivine macrocrysts, and smaller subhedral to euhedral olivine phenocrysts. The well-crystallised groundmass consists of monticellite, phlogopite, spinel, primary carbonate, serpentine, and perovskite. Mantle xenocrysts, in addition to
olivine macrocrysts, include rare garnet and clinopyroxene. Ilmenite is not present. Rare mantle xenoliths consist of garnet lherzolites and eclogites. Country-rock xenoliths are predominantly granitoids exhibiting extensive reaction to the host
kimberlite, and these xenoliths range in colour from black to white. In areas where significant digestion of granitic country rock xenoliths has occurred, the groundmass is characterised by common phlogopite and/or clinopyroxene reflected in a
patchy colouration of the rocks.

|      | Brecciated contact zones are characterized by fractured country rocks that do not contain any kimberlitic component. The variable fragment sizes and shapes range between 0.5 mm to 15 cm. In general, the brecciated zones can be
subdivided into two main groups: massive brecciated zones (MBZ) and pulverized brecciated zones (PBZ).

MBZ consists of coarser fragments typically greater than 2 cm in diameter. These zones are often associated with pre-existing joints. The fragments within these zones are typically loose and have not been cemented.  The distribution and extent of
these broken zones is highly variable and generally increases in intensity as the pipe contact is approached. However, at a distance from the pipe contact, there are contacts without brecciated zones directly adjacent to contacts with brecciated
zones. This apparent haphazard distribution of the brecciated zones may be related to the interconnectedness of the country rock joints. The broken country-rock fragments can often be fitted back together, with no evidence of particle movement.

PBZ consists of a mixture of larger particles 2 cm to 15 cm in diameter with a matrix composed of finely pulverized country rock < 2 mm in diameter. These breccias are typically cemented. The PBZ can be either clast or matrix supported, and there
is often evidence of particle movement.  The proportion of fine pulverized material present within these zones is highly variable.  Often the larger fragments contain smooth edges and show slight alteration or bleaching along the margins. The PBZ
zones are not as common as the MBZ. These breccia zones are interpreted by GKJV to be related to pre-conditioning processes in the early emplacement of the kimberlite. Once the kimberlite has breached the surface, it is thought that the subsequent
explosion and violent degassing of the magma column likely incorporated the weak brecciated zones into the pipe.  Large xenoliths of this material are present within the Tuzo pipe.

Chemically-altered Contact Zones

These are characterized by typically minor (< 5 cm) zones of alteration along joint surfaces without significant disaggregation.  The intensity of this alteration is variable; however, this decreases in intensity with increasing distance from the
pipe contact.  Chemically-altered contact zones are most often developed in areas around HK. These zones can also contain brecciated country rock.  The altered zones typically are pale yellow in contrast to the pink granitoids. These areas can be
porous due to the removal of quartz.

Chemically-altered and Disaggregated Contact Zones

These zones are considerably weaker and more extensive than the chemically-altered contact zones where present. These areas are characterized by typically extensive chemical alteration that, in extreme cases, can result in extensive disaggregation
of the country rock. These zones are also characterized by minor brecciation, but without evidence of transport or cementation. This type of contact zone is most extensively developed in areas around

    HK and, in particular, within the granite cap
over the 5034 North lobe. The most extensive zones are present over the thicker intersections of kimberlite. The altered zones consist of a brittle core that appears bleached (particularly along joints). Feldspars are typically orange in appearance
and in thin section appear sericitized. Chlorite and dolomite can be present along joint surfaces.

|      | These zones are only associated with hot contacts related to HK, and are typically less than 50 cm wide. Weakest adjacent to the kimberlite, the country rock displays less reaction to the intruding kimberlite with increasing
distance from the contact.

|      | Country-rock xenoliths within the Gahcho Kué kimberlite pipes are dominated by granitoid xenoliths with lesser diabase, gneiss, and rare volcanic rocks. No sedimentary-rock xenoliths are present. Xenolith contents of the
kimberlites are variable, particularly in the TK units. For logging purposes, the following terms are used to indicate xenolith abundance:

|      | The main Gahcho Kué kimberlite cluster comprises four pipes; the Hearne, 5034, Tuzo, and Tesla bodies. The Hearne pipe, most of the 5034 pipe, and the Tuzo and Tesla pipes occur under Kennady Lake (see Figure 2-2), which
has an average depth of 8 m. The kimberlites may represent the oldest known occurrences of kimberlite on the Slave Craton. The 5034 kimberlite was RbSr isotopically dated (phlogopite) as Middle Cambrian (542.2±2.6 Ma: Heaman et al.
2003). Hetman et al. (2004) suggest similar ages for the Tuzo, Tesla and Hearne kimberlites based on Ar40Ar39 dates on phlogopite that are 542±6, 531±6 and 534±11 Ma, respectively.

|      | The pipes are steep-sided and were formed by the intrusion of several distinct phases of kimberlite in which the textures vary from HK to diatreme-facies TK. TK displays many diagnostic features including: abundant unaltered
country rock xenoliths, pelletal lapilli, serpentinized olivines and a matrix composed of microlitic phlogopite
and serpentine without carbonate.
    HK contains common fresh olivine set in a groundmass composed of monticellite,

phlogopite, perovskite, serpentine and carbonate. A number of separate
phases of



kimberlite display a magmatic textural gradation from TK to
HK, which are characterized by a decrease in the proportion of pelletal lapilli
and country rock xenoliths, and an increase in groundmass crystallinity,
proportion of fresh olivine, and the degree of xenolith digestion (Hetman et al.
2004). Characteristics of each pipe are summarized in Table 7-1.

|      | Two bodies comprise the Hearne kimberlite, Hearne South
      and Hearne North (Figure 7-4). The bodies have smooth, steep-sided walls,
      and cover an area of about 1.5 ha. Hearne South is a roughly circular
      pipe, whereas Hearne North is a narrow, elongate pipe trending
      northsouth. The pipes may join at depth. The width of country rock
      between the two bodies varies from a minimum of approximately 20 m at the
      sub-crop to approximately 70 m at depth. Hearne North measures a maximum
      of 250 m x 50 m northsouth. Hearne South has a dimension of about 80 m x
      90 m at surface. Hearne South is dominantly infilled with TK, and Hearne
      North is infilled with approximately equal amounts of HK and TK.

|      | The present pipe geological model for Hearne South
      extends to 225 masl; there is no drill information below this level. At
      Hearne North, the pipe narrows to less than 10 m wide in the centre of the
      body at approximately 130 m below lake-surface. There is also evidence at
      the north and south ends of the body that the pipe extends below 115
      masl.

- 5034 South Pipe (that occurs along an interpreted dyke, the Southwest Corridor, that is also modelled incorporating the Wallace and TKBBB drill core intersections)
- 5034 main West Lobe
- 5034 main Centre Lobe
- 5034 main North-East Lobe (i.e. East Lobe and North Lobe)
- 5034 North Pipe.

The main part of the 5034 occurrence that reaches the surface occurs under Kennady Lake and can be divided into three lobes: West, Centre, and East. These three lobes are joined at the surface, but separate at depth.  The Centre and East Lobes are
modelled separately at shallow depth, but rejoin at greater depth producing what appears to be a window of granite within the kimberlite. The East and North Lobes are joined at depth, geologically continuous, and are collectively referred to as the
North-East Lobe.  The surface measurements of the three lobes of the 5034 main pipe are approximately as follows:

- West Lobe  125 m x 45 m
- Centre Lobe  125 m x 80 m
- East Lobe  85 m x 65 m.

The northern portion of the 5034 North-East lobe, the North Lobe, is blind, and occurs under 60 m to 90 m of country-rock cap. Approximately half of this northern lobe lies below the lake bed and half beneath the main peninsula. The blind northern
portion of the 5034 North-East Lobe measures 240 m long and varies from approximately 20 to 50 m wide, averaging 30 m wide. A combined internal geology model is developed for the 5034 North-East Lobes. There are four major kimberlite types, three of
which occur across both lobes (refer to Figure 7-6).
The modelled 5034 kimberlite occurrence includes two small satellite intrusions, the 5034 South Pipe and the 5034 North Pipe, which are modelled separately from the main 5034 body due to very limited information on these bodies.
Some areas of the 5034 pipe contacts remain poorly defined; the current 5034 kimberlite model incorporates the South Pipe along an interpreted dyke informally termed the Southwest Corridor, extending southwest from the West Lobe (refer
to Figure 7-6). The 5034 South Pipe extends as deep as 305 masl, the maximum depth of the available information. The 5034 South Pipe and the 5034 West Lobe appear to be connected by a complex breccia (TKBBB). Interpretation of drilling
data suggests connectivity between the western Wallace kimberlite occurrence, the 5034 South Pipe and the main West Lobe along the main trend of the 5034 deposit. The modelled Southwest Corridor extension of the 5034 kimberlite measures
as much as 330 m long and varies from approximately 5 m to 40 m in width.
Based on petrographic observations and whole-rock geochemical data, a systematic arrangement of lithofacies types was recognized. HK textured kimberlites are located in deeper levels of the pipe, followed by transitional textured kimberlites (HKt
and TKt) until fragmental textured kimberlites (TK) dominate in the uppermost portions of the pipe. TK and TKt textured kimberlite are present in the West and North-East Lobes. The Centre Lobe is dominated by HK.
Four main textural kimberlite units are identified in the 5034 North Lobe: TK, TKt, HKt, and HK (Kryvoshlyk, 2006). The spatial distribution of those rock varieties creates an antiformal structure located approximately in the geographical centre of
the lobe. The most important rock types in the North Lobe are HK and HKt, which
are present in the deeper levels of the lobe and

comprise the saddle of the antiform. TK and TKt rock types are mainly present in the shallow levels of the flanks in
the North and South of the antiform and are overlying the HK units. A specific
unit, the so called Orange Marker, is identified in thin sections throughout
the North Lobe. A selected suite of kimberlite rocks from the East and North
Lobe were examined, and the samples were concluded to show well developed
petrological similarities suggesting a close genetic relationship of the two
lobes (Kryvoshlyk, 2007).

Kryvoshlyk (2008) showed that the North-East and West Lobes have an overall layered internal structure, comprising gradual kimberlite textural  changes from coherent HK at depth to fragmental TK at shallower levels. Transitional rocks in between
these end member coherent or fragmental rocks are either called HKt or TKt, depending on their textural association. In contrast to the layered structure of most lobes, the Centre Lobe is composed exclusively of HK, which could not be subdivided
with available petrological or geochemical data despite the variable diamond counts in this Lobe.  The HK found in all four lobes is geochemically and petrologically similar, suggesting a close genetic relationship between all four lobes.

Kryvoshlyk (2008) concluded that the quality of the geological model is strongly dependent on the data density (drill core and reference samples) and on sample collection protocols. The highest data density is present in North-East Lobe, which
results in a relatively high-confidence model. The West and Centre Lobes have a lower data density (both with respect to drill density and number of reference samples) and rather poor sample control (difficulties connecting micro-diamond and heavy
mineral samples with geology).  It is therefore not possible to produce a high-confidence geological model for West Lobe or to explain the diamond data variability in Centre Lobe without additional data. The Centre Lobe is composed almost entirely
of HK, and minor HKt.  With the dataset available in 2008, the HK rock types are petrographically and geochemically indistinguishable; thus Kryvoshlyk (2008) recommended that they be modelled as one unit. The West Lobe is to some extent similar to
the North-East Lobe in that the sequence HKHKtTKt is present, and these rocks are petrologically similar. The West Lobe is divided into three petrological units, a Main Lower HK unit, a Main Upper HKt unit, and a Secondary Upper TKt
unit; however, significant uncertainty is associated with the contacts between those units, and the resource model considers the pipe to be undifferentiated kimberlite.

Tuzo Kimberlite

Seghedi and Maicher (2007) presented new petrographical, geochemical and micro-diamond data for Tuzo pipe with the purpose of developing a 3D internal geological model. The 2007 study refined the previous internal geology model (Hetman et al., 2003
and Hetman et al. 2004) and reassessed the diamond distribution model. The overall surface area of the Tuzo pipe is about 1.2 ha, which is covered by as much as 25 m of water of and glacial overburden. The kimberlite body comprises various
fragmental and coherent kimberlites, and it contains abundant inclusions of the surrounding granitic country rock. The 2007 drill program improved the definition of the shape of the pipe, which is unusual as it widens towards depth from 125 m in
diameter near the surface to about 225 m diameter at 300 m depth (Figure 7-7).

Seghedi and Maicher (2007) reported that the internal geology of Tuzo is very complex. Abundant country rock xenoliths, ranging from a few mm diameter up to blocks several tens of meters in size, are hosted within the pipe. The highest degree of
dilution is concentrated along a belt-like zone at about 120 to 200 m depth and under the roof of the widening pipe.  The distribution of lithologies follows, very generally, a trend from top to bottom: TK, TK-TKt, and TKt as well as HKt+TKt, HKt,
and HK.  On a more detailed scale, however, the different lithologies occur as several metre to tens of metre thick intercalated sections, and HK as well as HKt are found at all levels within the pipe, although they are more abundant at depth.
Contacts in between the kimberlite rock types are mostly gradual. The lithological units show limited horizontal extent. Instead, they appear steeply to sub-vertically oriented, which gives

the Gemcom® internal geology model a rugged shape.
Volcanological evidence for mixing and mingling processes combined with the general facies architecture strongly suggest the occurrence of multiple eruptive events that modified the
pipe infill extensively.

Seghedi and Maicher (2007) stated that the geochemical signature of the lithologies is strongly influenced by the variable but generally high degree of country-rock contamination. Fragmental kimberlite units are geochemically and petrologically very
similar, suggesting a close genetic relationship. However, the coherent kimberlite types HK and HKt are slightly discordant to the geochemical trend defined by the fragmental kimberlites, and are possibly related to a separate batch of magma.  The
HK and HKt units also have higher diamond counts.  The diamond distribution in the pipe is difficult to interpret (Seghedi and Maicher, 2007).  Volumetrically significant lithologies with elevated diamond counts are found in the coherent HK and HKt
units at depth.  The fragmental lithologies in contrast have lower stone counts, which seem to correlate inversely with country-rock dilution.

In its shallow levels the pipe contains a zone that is characterized by a higher diamond grade and lower dilution compared to the surrounding fragmental rock units. This High Grade zone was originally identified in 1998 from large diameter drilling
(LDD) data due to a zone of higher macro-diamond grade (Williamson and Hetman, 1998). Subsequent logging and re-logging of existing core suggested minor petrographic differences between the High Grade zone and the adjacent low-grade area, but also
considerable textural inhomogeneities within the High Grade zone itself (Podolsky et al., 2002; Hetman et al., 2004; Scott Smith Petrology Inc., 2005; Mineral Services, 2007; Seghedi and Maicher, 2007; Webb, 2007).

In the geological model developed by Seghedi and Maicher (2007) the TKt_1 and TK-TKt_1 model codes form a low dilution zone that includes the pre-2007 high-grade unit. The High Grade zone shows considerable internal inhomogeneities and a high
similarity to neighbouring fragmental units (TK and TK-TKt_2) with respect to many petrographical parameters as well as its mineralogy, whole rock chemistry and micro-diamond (stone counts and size frequency distribution) data. Differences are the
generally lower degree of dilution and a higher-grade with a coarser stone distribution.

A limited groundmass-spinel study suggests that most samples from the TK-TKt_1 High Grade Zone model code and the adjacent fragmental kimberlites overlap and show no significant chemical difference. Two of the analysed High Grade zone samples are
chemically similar to an HKt sample from greater depth suggesting that the High Grade zone is a relatively undiluted feeder conduit through the surrounding tephra of the TK and TK-TKt_2 units.

While the grade differences can be explained by the lower degree of dilution in the High Grade zone, the coarser stone distribution is likely a signature of the original tephra jet, which, in turn, leads to the conclusion that the coherent magmas at
depth (> 300 m) have also the potential for a favourable coarse stone distribution.

Gostlin (2008) developed a Gemcom® solid model that delineates the High Grade zone based on grade data.  The High Grade zone is almost entirely contained within the northeastern portion of the pipe, in the TK-TKt_1 unit, but is
smaller than the TK-TKt_1 unit.

AMEC is of the opinion that the geological setting and local geology are adequately known to support Mineral Resource estimation and mine planning.

5034 South could benefit from additional drilling to better define the limits of the body, whereas 5034 West could benefit from additional drilling to better define internal geology.

All bodies remain open at depth.

8.0

DEPOSIT TYPES

The composite geological model of the Gahcho Kué kimberlite pipes (Figure 8-1), as well as the shape and infill of the individual kimberlite pipes, is similar to that of the kimberlites located in the Kimberley area of South Africa. They are,
however, different from many other Canadian kimberlites such as those found at Fort à la Corne, Attawapiskat, and Lac de Gras (Field and Scott Smith, 1999). In general, the other Canadian deposits comprise the upper levels of the pipes. The
Fort à la Corne pipes are preserved as craters with kimberlite pyroclastic aprons around the craters.  The Lac de Gras pipes are preserved as diatremes below the surficial craters and above the root zones.  Gahcho Kué pipes preserve
minor pyroclastic kimberlite attributed to the diatreme, but largely contain root-zone materials.

Hetman et al (2003) interpreted the Gahcho Kué pipes to be similar root-to-diatreme transition zones to those described by Clement (1982) and Clement and Reid (1989).  According to Hetman et al (2003), the variations in pipe morphologies and
infill displayed by the Gahcho Kué kimberlites reflect varying depths of diatreme development and are not a function of different depths of erosion for each of the pipes according to Hetman et al (2003).

With respect to emplacement, Hetman et al (2003) stated that the observed gradational TK to HK textures at Gahcho Kué are consistent with the interpretation by Clement (1982) and Clement and Reid (1989) in which the degassing of an intrusive
magma column produces the diatreme zone, with the underlying transition diatreme root zone representing a frozen degassing front, as discussed by Field and Scott Smith (1999).

Kryvoshlyk (2008) considered that the diamond distribution in the 5034 NorthEast Lobe appears to follow the layered character of the kimberlite overall. Maximum concentrations of diamonds are often located close to the Orange
Marker  a specific petrological layer generally found between the two units comprising the majority of the pipe infill: the Upper HKt and the Lower HK units. Kryvoshlyk (2008) further maintained that the diamond count maxima specifically
in the East Lobe appear to create a lens-like body at a depth of 85 to 131 m towards its flanks and 107 m to 211 m in its centre.

Seghedi and Maicher (2007) reported that overall, the diamond distribution at Tuzo appears to be unrelated to spatial or depth levels, but is more related to the abundance of dilution in an area. This in turn confirms the geological observations and
geochemical data. The pre-2007 established Tuzo high-grade unit could not be confirmed as separate using the micro-diamond data obtained from the 2007 drill program. However, the 2008 LDD program confirmed that higher macro-diamond grades occur in
this zone, and the High Grade zone was re-incorporated into the 2007 resource model. The Seghedi and Maicher (2007) investigation demonstrated that the Tuzo pipe is geologically much more complex than previously thought.

|    |                  
|9.1 | Hearne Kimberlite

Five different phases of TK were recognized within the Hearne kimberlite. Each TK phase can be geologically distinguished using features such as varying proportions of garnets, magmaclasts, autolith-like bodies, xenoliths, and clay minerals. The
names of the different TK units are based primarily on their location within the two pipes.  The greenbrown, partly-altered TK units are easily distinguished from the fresh black HK in both core and reverse circulation drill cuttings.
Different phases of kimberlite within the black HK units are very difficult to distinguish from one another. The total HK was sub-divided into three units based primarily on macro-diamond grade with some support from geological differences and
spatial positions in the pipe.

9.1.1

Hearne North

A major TK unit in Hearne North is the HNTKN that occupies the upper northern part of the main pipe. This TK contains <15% of granite xenoliths but does contain autolith-like bodies and magmaclasts.  The TK grades with depth into transitional
textures grading towards HK. The transition zone was termed HNTKNt. This unit was geologically modelled using the upper limit of HK and the lower limit of TK textures logged in both core and reverse circulation holes. Below the transition zone is
HK, some of which appears to be of the same phase of kimberlite as the overlying TK and TKt. The internal contact separating the TKN and TKNt is sub-parallel to the contact with the underlying HK. Both internal contacts dip at approximately 50°
to the north. The HK immediately underlying the HNTKNt is thought to be part of the same phase and was termed HNHKN. This interpretation is supported by the similarity in macro-diamond grade between the textural varieties of kimberlite. These three
textural units (HNTKN, HNTKNt, and HNHKN) represent the transition from the diatreme to the root zone within a single phase of kimberlite.

Two smaller TK units, which are unrelated to those discussed above, are present in Hearne North. HNTKG2 is located near the surface at the southern end of the pipe. This unit also seems to grade into an underlying HK, termed HNHKG2.  One of the main
features that distinguish the two smaller TK units from the main HNTKN is the presence of fresh garnets in the former.  The HNTKSD is interpreted to be a completely different, and probably earlier, phase of kimberlite partly because the HNTKN and
HNTKG2 exhibit gradational changes to HK at shallower levels in the pipe than the HNTKSD.

Although the HNHKN, discussed above, is interpreted as being related to the HNTKN, other HK units appear to be unrelated. Geologically, the latter HK units seem to contain more garnets than the HNHKN. There also appears to be sharper contacts rather
than gradational changes between these and the overlying TK units.  The volumetrically largest of these HK units, HNHKG, is correlated with the low-grade areas within the HK found in many of the large diameter holes. The HNHKG2 is nearly
indistinguishable from the HNHKG in core.

|      | Based on geological interpretations from limited core drilling, this body appears to be composed mainly of uniform diatreme-facies TK, containing as much as 50% granite xenoliths. The TK unit was named HSTKM. A separate
transitional HK/TK was proposed and named HSTKW. The macro-diamond grades in both of the above units are similar.

Kryvoshlyk (2008) reported that the diamond distribution in the 5034 North Lobe appears to follow the layered character of the kimberlite overall.  Maximum concentrations of diamonds appear often located close to the Orange Marker 
a specific petrological layer generally found between the two units comprising the majority of the pipe infill  the upper HKt and the lower HK units. Diamond count maxima in the East Lobe appear to create a lens-like body at a depth of 85 m to
131 m towards its flanks and 107 m to 211 m in its centre.

Limited diamond and geological data for the Centre and West lobes did not allow Kryvoshlyk (2008) to produce high-confidence 3D models. The Centre Lobe macro-diamond distribution is highly variable and was found to be poorly supported by petrology,
even between relatively closely-spaced drill holes. The Centre Lobe micro-diamond distribution showed the presence of high-grade zones, which did not correlate with petrological changes. The resource model considers the West Lobe to be
undifferentiated kimberlite and the Centre Lobe to be composed entirely of undifferentiated HK.

Kryvoshlyk (2008) concluded that the generation of the transitional kimberlite rock textures at 5034 is still poorly understood.  If the transitional rock types are in-situ differentiates of HK magma, Kryvoshlyk (2008) maintains that they should
play only a minor role in understanding the diamond distribution.

9.3

Tuzo Kimberlite

Seghedi and Maicher (2007) reported that the kimberlite units of the Tuzo kimberlite pipe are characterized by a large variation of diamond counts in both micro as well as macro grain size classes.  One of the aims of the 2007 drill program was to
better delineate the pre-2007 established high-grade and low-grade units. The diamond distribution in the pipe is difficult to interpret according to Seghedi and Maicher (2007). Volumetrically significant lithologies with elevated diamond counts are
found in the coherent HK and HKt units at depth. The fragmental lithologies in contrast have the lower stone counts, which seem to correlate negatively with country rock dilution.  Seghedi and Maicher (2007) maintained that overall, the diamond
distribution appears to be unrelated to spatial or depth levels, but more correlated with the abundance of dilution in an area.  This in turn confirms the geological observations and geochemical data.

A previous interpretation of the emplacement mechanism of the Tuzo pipe by Hetman et al (2004) proposed that the pipe is a transition zone representing a frozen degassing front of a single phase of intrusive kimberlite.  Seghedi and
Maicher (2007) concluded that the emplacement of the Tuzo pipe was a process extended over a period of time with repeated eruptions of variable magnitude and nature, with resedimentation and recycling of volcaniclastic material being evident.

Micro-diamond stone counts per sample were found by Seghedi and Maicher (2007) to be highly variable, both within and in between geological units. The abundance of xenoliths within a sample correlated negatively with total stone counts, and thus the
highly variable degree of country-rock dilution is thought to contribute to the large range of counts. According to Seghedi and Maicher (2007), the pre-2007 high-grade unit could not be confirmed with micro-diamond data obtained from the 2007 core
program. The pre-2007 high grade unit was found to have, on average, a lower degree of dilution than the surrounding lower grade unit.  For the high grade unit, no criterion was found by Seghedi and Maicher (2007) to consistently discriminate the
unit.

It was concluded by Seghedi and Maicher (2007) that:

- The kimberlite units of the Tuzo kimberlite pipe are characterized by a large variation of diamond counts in both micro as well as macro grain size classes.
- Distinctive differences in the absolute value of diamond stone counts of fragmental versus coherent units, which appears partly related to their degree of dilution, but also to possibly different batches of magma.
- The stone counts are strongly affected by the degree of dilution. However, no distinctive separation of or internal homogeneity within a unit is found by eliminating the dilution. Outliers occur in country rock xenolith rich breccia zones.
- A distinct correlation of stone ratios is not found for any of the lithologies. (Ratios of diamond grain size classes are expected to be constant within a unit, irrespective of various effects that alter the absolute numbers of stones, including the
degree of dilution. Thus, individual batches of magma that have sampled different areas of the mantle for diamonds are expected to have different stone size ratios).
- Geochemically some of the element vs. micro-diamond data plots indicates a subtle correlation of the major model codes distinguished in Tuzo kimberlites, although extensive scatter prevents the definition of a distinct criterion.
- For the pre-2007 high-grade unit, there was no criterion to consistently discriminate this unit, or even confirm its existence as a separate unit.

Stiefenhofer (2008b) reported an investigation to attempt to clarify the apparent existence of a high-grade unit in the Tuzo pipe, and commented on the validity of retaining this unit in the geological model.  The investigation focused on a review
of observations by past workers, reappraisal of new geochemical data generated in 2007, the methods used to calculate crustal
dilution, distribution of granite dilution within the pipe, distribution of diamond grade within the pipe, and lastly consideration of the potential role that volcanic processes may have played in the generation of the high-grade feature.

Stiefenhofer (2008b) concluded that geological evidence for the existence of a High Grade zone was circumstantial at best.  Stiefenhofer (2008b) stated that ultimately however, it appears that the High Grade zone was derived from magma with similar
rare earth element (REE) chemistry compared to the remaining fragmental units.

It should be noted that the 2008 RC drilling mini-bulk sampling program did confirm the high macro-diamond grade zone delineated by the 1999 RC drilling mini-bulk sampling program (see Sections 12.3 and 17.2.1) .

The possibility of a temporary obstruction during the course of the eruption and emplacement of the Tuzo pipe was considered by Stiefenhofer (2008b) to be the most likely explanation for the High Grade zone. He speculated that the introduction of
the granite raft, combined with the additional smaller blocks and fragments of granite, proved to be too voluminous for the volcano to eject at once. The feeder was forced to deviate around this obstruction, and the eruption continued. The 3D
orientation of this zone of granite debris (defined largely by unit TKTKt_2) suggested to Stiefenhofer (2008b) that the new vent position was located along the eastern wall of the pipe. It is possible that the proximal position to the vent may have
locally influenced the diamond stone size and grade, thereby defining the High Grade zone.

Tappe (2009) reported on a preliminary groundmass spinel chemistry study to support the evaluation of a reconciliation of a high-grade unit with the 2007 Tuzo geological model. Tappe stated the data suggested that the High Grade zone of unit
TK-TKt_1 and the low-grade unit TK-TKt_2 are derived from a common magma batch and that the difference in diamond grade is primarily a function of country rock dilution. The analyzed low-grade units contain multiple spinel populations, some of which
are not observed in the High Grade zone. This suggests that mixing of different magma batches occurred.  According to Tappe, there appears to be an affinity of the TKt_1 model code, which is part of the high-grade material close to the surface, to
HKt material at greater depths.

Other Kimberlites

GKJV has intersected a number of additional kimberlites by drilling into geophysical anomalies. These are generally of very small size with little to no grade and include Tesla, Dunn, Faraday, Kelvin, 5034 South, North Pipe, and Wallace. No
additional work is planned for these pipes at this time.

9.5

Comment

The kimberlite geology and mineralization within the Hearne, 5034, and Tuzo pipes is in general quite well understood, and is adequate to support Mineral Resource estimation.

The 5034 West and Centre Lobes require additional drill-based data to fully understand the complexity of the geology within these lobes.

The Tuzo pipe, between 12161 masl, and the Hearne pipe, between 217121 masl, are currently classified as Inferred Mineral Resources.  To support higher-confidence Mineral Resource classifications, additional drilling would be required in
this area.

All pipes are open at depth, and would require further drilling below 121 masl. The area below 121 masl may have some potential for additional diamond mineralization at Gahcho Kué.

EXPLORATION

Exploration activities on the Gahcho Kué Project have included geological mapping, geochemical sampling, and drilling by multiple operators. Exploration activities and results are discussed in the following subsections.

Activities were conducted either by De Beers personnel on behalf of, and as directed by, the GKJV, or by consultants and contractors appointed by the GKJV and supervised by De Beers as Project operator.

10.1

Survey

The Gahcho Kué site was surveyed by GKJV in 1998 using the North American Datum (NAD) 27 coordinate system, with elevations recorded in Height Above Ellipsoid (HAE)1.

All pre-2004 drill hole collars at Gahcho Kué were surveyed using UTM NAD 27 Zone 12. Pre-existing survey control for the Base Station at the site references a First Order Geodetic Monument located near the Hoarfrost River.  This coordinate
was established by global positioning system (GPS) survey between 1996 and 1998 by GKJV. A surface grid tied to the UTM system was established during 19971998 over each of the kimberlites.  Several permanent reference points within each grid
were established on land using a Trimble 4800 series GPS. These reference points were re-occupied by GKJV in 1998 with a Trimble 4800 series GPS, which confirmed the accuracy of the original locations (Hodgkinson, 1998).

From November 2003 to January 2004, GPS determination of Canadian Active Control Network (CACS) NAD 83 coordinate values with elevations in masl for the GPS Base Station at Gahcho Kué was performed using two independent methods (Hewlko,
2004). The first method involved the processing of CACS data and satellite data collected at the base station in November 2003 and January 2004.  The resulting six positions agreed within 3 cm in the northing direction, 3 cm in the easting
direction, and 9 cm in elevation. The second method of determining the position of the base station was to process the data observed at the base station by single point positioning. The six positions agreed within 0.6 m in the Northing, 1.1 m in the
Easting and 1.7 m in the Elevation. All drill hole collars surveyed for the 2004  2008 drilling programs utilized Real Time GPS CACS NAD 83 coordinates.

Unless otherwise noted, drawings and coordinates are based on the NAD83 coordinate system, with elevations in masl, and are all referenced to the CACS benchmark located in Yellowknife.  The following shifts were used to convert the NAD27 HAE system
to CACS NAD83 masl:

- Northing Shift:
+221.619 m
- Easting Shift:
-64.211 m
- Elevation Shift: +16.917 m.

__________________________
1 The term above mean sea level (amsl) refers to the elevation (on the ground) or altitude (in the air) of any object, relative to the average sea level datum. As sea level can vary depending on air pressure, an alternative can be used, where base
height measurements are referenced to an ellipsoid of the entire earth. HAE is the base reference for all GPS instruments.

The shifts noted above differ from the theoretical shift between NAD27 HAE and NAD83 masl because of the enhanced survey accuracy achieved by tying into a CACS benchmark.

10.2

Geological Mapping

A 16 square kilometre area near Kennady Lake was selected in 1998 for geological mapping at 1:2000 scale) using airphoto bases. The purpose of the mapping project was to document the bedrock geology, structural geology, surficial geology (overburden
type), and drainage patterns within the area.

10.3

Exploration Programs

No work was conducted by the original claim staking company, Inukshuk. Exploration between 1992 and 1996 was conducted by Canamera Geological Ltd. (Canamera) as the operator for MPV and its predecessor company Mountain Province Mining.  From 1997,
the GKJV was responsible for all exploration, with De Beers as operator performing the work as directed.

10.3.1

Canamera Geological Ltd.

Canamera Geological Ltd. acted as the operator for Mountain Province Mining Inc. prior to the joint venture with Monopros Ltd. (De Beers).  Exploration work carried out by Canamera between 1992 and 1994 comprised 993 reconnaissance and follow-up
glacial-till samples and an airborne electromagnetic survey.  From 1995 to 1996, additional exploration included bedrock and surficial mapping, airborne and ground geophysical surveys, and collection of 1,842 sediment samples.

In January 1995, the AK5034 (5034) kimberlite was discovered, and from 1995 to 1996 it was tested by 68 exploration and delineation NQ core holes.  In addition to the core drilling, geotechnical investigations of the kimberlite were completed by
Canamera and Bruce Geotechnical Consultants Inc. Data collected included core recovery, rock quality designation, lithological information and alteration, point load tests, preliminary determinations of rock mass types, strength ratings, and
preliminary determinations of slope requirements for rock mass types.

In 1996, a 105.2 t mini-bulk sample of the 5034 kimberlite was obtained by PQ core drilling of 43 holes for macro-diamond recovery. Material from NQ delineation holes completed in 1996 contributed an additional 10.2 t to the mini-bulk sample.

|       | Initial exploration by the joint venture in 1997 comprised a low-level airborne magnetic and five- frequency electromagnetic (EM) survey over the AK property. Geophysical anomalies generated from the surveys were followed by 2,211
sediment samples, 652 m of NQ core in five holes and 85.35 m of reverse circulation drilling in four holes. A total of eight targets were identified in the AK Property from this work, and included the discovery of three additional kimberlites: Tesla
in May 1997 and Tuzo and Hearne in August 1997. Delineation drilling on the four kimberlites (including 5034) comprised 9 NQ diamond holes for 2658.89 m.

Petrography, Mineralogy and Other Studies

Detailed petrography and mineralogy is an integral part of GKJVs exploration process. Reports include Caro and Kopylova (2004), Hetman et al. (2004), Kryvoshlyk (2007), Seller (2008), and Kryvoshlyk (2008).

Details of methodologies are discussed in Webb et al. (2006), Field and Ferreira (2006), Seghedi and Maicher (2007), Stiefenhofer (2007), and Kryvoshlyk (2008).  Methods include abundant use of thin sections and polished slabs, detailed mineral
counts, and whole-rock geochemistry.

Hydrology and Geotechnical

Golder Associates (Eichenberg, 1999) trained GKJV personnel in the geotechnical aspects of core logging, and in 1999 a geotechnical study was performed by Golder Associates (Eichenberg, 1999). The Laubscher rock mass classification system was used
to assess the geotechnical data.  Geotechnical units identified were based on fracture frequency, rock strength, and joint conditions, in country rock and in kimberlite.  The following work was performed:

- core orientation, fracture frequency, rock strength and joint conditions were measured
- rock mass rating and rock mass strength for each unit were calculated.

Point load testing of kimberlite and country-rock xenoliths from the Tuzo 2002 HQ core specimens was performed (Charlebois; 2003).  The aim of this exercise was to obtain fresh point-load strength index data for comparison against possible future
rock-strength classification by ore dressing studies (ODS).

Geotechnical and geohydrology consultants were employed on site during the 2004 drilling program for detailed logging. A standard geotechnical logging template developed by SRK was used to record field drill hole data, including geotechnical logs,
field geological log, density sample results and down-hole survey measurements. A site-specific geotechnical discontinuity atlas was produced. SRK supervised a geotechnical drilling program in the area of proposed open-pit mining, comprising
geotechnical logging and an assessment of geological structures, rock strength, and hydrogeology for pit design and slope optimization.

Hydrology and geothermal drilling programs were also completed in 2004, supervised by HCI Hydrologic Consultants, Colorado USA. Work comprised hydro-structural drilling of faults and potential lake dewatering dykes.  Hydrological data for
hydrological modelling were tied into environmental baseline studies. Packer testing was undertaken at 3 m and 912 m, for a total of 141 test intervals.  Sub-permafrost sampling was undertaken, as was 5034 proposed pit water sampling, where 12
airlift tests at 30 m intervals were completed. To collect geothermal data for modelling to tie into environmental baseline studies, thermistors were installed at a depth of 250 m.

Comment

Exploration to date at Gahcho Kué is consistent with industry-standard practices and is appropriate for the type of mineralization. Exploration is adequate to support Mineral Resource estimation.

DRILLING

Drilling completed to date on and surrounding the Gahcho Kué kimberlite cluster totals 504 drill holes (96,493 m). An additional 50 drill holes were completed on exploration targets located away from the Gahcho Kué cluster.  A summary
of drilling completed on the Gahcho Kué Project is provided in Table 11-1. Drill hole locations are presented in Figure 11-1. Core holes included PQ (85 mm), HQ (63.5 mm) and NQ (47.6 mm) core sizes, and 76 mm tricone drilling for overburden.
RC drill diameters included 140 mm, 149 mm, 324 mm, 334 mm and 610 mm sizes.

Exploration drilling programs were performed during 19952003 around the Gahcho Kué kimberlite cluster to test geophysical anomalies, discover kimberlites, define pipe boundaries and morphology, delineate internal geology and provide
large diameter reverse circulation drill (LDD) mini-bulk samples for value and grade evaluation purposes.

Other exploration holes targeted surrounding geophysical and mineral indicator train anomalies that resulted in the discovery of several smaller satellite pipes, none of which has received more than first-pass drill evaluation following
disappointing micro-diamond grades.

Drilling between 2004 and 2008 comprised LDD and large diameter core (LDC) mini-bulk sample, programs, core drilling to provide information to support advanced evaluation geology, Mineral Resource estimation and ore dressing studies, civil
engineering, geotechnical, hydrological, and geothermal core drilling programs. These drill programs also provided core that was used to inform and support environmental baseline studies.

The following sub-sections briefly discuss the drilling programs on a program-by-program basis.

|       | Canamera conducted the earliest drilling and discovered the 5034 kimberlite. Drilling in 1995 included 39 delineation NQ core holes (6,522 m). During 2006, 43 PQ holes (11,630.18 m) and 33 NQ core holes (9,334.64 m) were drilled
at 5034. Drilling was to provide core for mini-bulk sampling (PQ holes). The NQ exploration holes tested source areas for kimberlite indicator mineral trains and geophysical anomalies in addition to delineation of the 5034 kimberlite.

|       | The Dunn anomaly was delineated as a circa 850 m long, 50 m wide, northeast to north-northeast trending conductive linear feature, located about 250 m west of the 5034 and Tuzo kimberlites. The three inclined core holes were
drilled over a strike distance of about 425 m. These holes intersected a zone of kimberlite sheets and stringers intruded among diabase and altered granite up to about 35 m wide. Individual kimberlite sheets were up to about 1.7 m thick, and the
diabase ranged in thickness from 1.7 m to 21 m.

A total of 43 holes (1,424 m) were located at proposed lake dewatering containment dykes for design, including structural, hydrological and geothermal data:

- 30 m shoreline thermistors: 24 drill holes (754 m)
- lake sediment and lake bedrock drilling: 19 drill holes (670 m).

Recovery of 11 t of kimberlite from 18 holes (2,482 m) for characterization of metallurgical properties for process plant design was required.  About 13.5 t of material was shipped to external laboratories, comprising 889 m of kimberlite from 5034,
and 915 m of kimberlite from Hearne. This drilling overlapped with Mineral Resource delineation, density, rock strength, acid rock drainage (ARD) programs. A total of 30 holes (325 m) was designed to test areas that could support the proposed plant
and waste dump locations to aid in conceptual mine design:

- 20 m thermistors: 6 drill holes (123 m)
- 30 m thermistor: 1 hole (32 m)
- Probe: 23 drill holes (about 170 m).

The 2005 hydrogeology drilling program entailed drilling of two HQ-size regional holes and two HQ core holes in the proposed Hearne and 5034Tuzo pit areas for environmental baseline studies.  Two additional holes were abandoned.  A total of
1,780 m were completed. Installation of Westbay piezometer instrumentation took place in the four holes drilled to target depths (1,670 m of the 1,780 m total drilled), with packer testing, pressure profiling and formation water sampling being
conducted.

The 2006 advanced evaluation core drilling program was based on a combination of 31 HQ drill holes (9,218 m) sited for Mineral Resource estimation purposes, and geotechnical data collection:

- Mineral Resource delineation 5034: 3 HQ core holes: 720.35 m
- Mineral Resource delineation Tuzo: 9 HQ core holes: 2,186.41 m
- pilot holes 5034 North lobe: 4 HQ core holes: 1,453.67 m
- pilot holes Tuzo: 2 HQ core holes: 702 m
- pit geotechnical 5034: 6 HQ core holes: 1,558.70 m
- pit geotechnical Tuzo: 5 HQ core holes: 1,681.85 m
- pit geotechnical Hearne: 1 HQ core hole: 250 m.

During 2007, a comprehensive core program of 27 HQ drill holes (8,574.26 m) was performed at the Tuzo kimberlite.  The work plan encompassed 8,400 m of core drilling designed to update data relating to kimberlite geology and volume, internal
dilution, density, and local grade (based on micro-diamonds). As part of this program, six 400 m deep holes were completed, and one 300 m deep hole was abandoned at 177 m, and re-drilled.

|       | Core drilling was extended in 2007 to include testing of the geological
continuity between the 5034 North and East Lobes, with five HQ core holes
(1,486.58 m). As a result of the drilling, data were obtained to support changes
to volume, internal geology, density and local grade (based on micro-diamonds).Macroscopic and thin section examination of 5034 East Lobe core confirmed geological continuity with the 5034 North Lobe.

GKJV (1998  2002)

There were four RC drilling mini-bulk and LDD bulk sampling programs conducted by GKJV between 1997 and 2002.  A 72 hole, 140 mm diameter, reverse circulation drilling program (7,197 m) was carried out in 19971998 at the Hearne, 5034, Tuzo and
Tesla kimberlites to confirm grades predicted by micro-diamond results obtained from core drilling. The drilling is summarized in Table 11-2. This was followed in 1999 by a 44 hole (10,451.20 m) LDD RC bulk sampling program.  The drilling method
employed was reverse-flood air-assist using mainly 311 mm diameter tricone bits, with 343 mm diameter tricone bits and one 371 mm diameter tricone bit also used in the 5034 kimberlite (Grenon et. al., 1999).  Program details are summarized in Table
11-3.

Evaluation bulk sampling in 2001 used a reverse-flood air-lift drilling method employing nominal 610 mm diameter tricone bits (Podolsky, 2001).  The East and Centre lobes of the 5034 kimberlite and the northern portion of the Hearne North kimberlite
were bulk sampled by nine holes (1,399.83 m), see Table 11-4. A total of 968.5 t of kimberlite was collected from the 5034 and Hearne North kimberlites.

The same drill method and drill size was used in the 2002 bulk sampling (Rikhotso, Williamson and Podolsky, 2002).  Thirteen holes (2,207.37 m) were drilled, comprising seven holes at 5034, in the West and Centre lobes, and six holes at Hearne
North, see Table 11-5.

___________________________________
2 The Recovery +1.0 mm% refers to the fact that during RC
drilling, a 1.0 mm screen was used at the drill rig to collect +1.0 mm material
(i.e. "Head Feed"). The -1.0 mm (refererred to as "underflow") is not collected
for processing and is disposed of in the field. The Recovery +1.0 mm % thus
refers to the +1.0 mm fraction Head Feed mass collected and processed, expressed
against the caliper mass. The caliper mass is the total mass measured down hole,
and thus includes the 1.0 mm fraction. Recovery +1.0 mm % is therefore the head
feed mass processsed, expressed as the percentage of the caliper mass.

The interval bulk sampled was 1,919 m (1,045 m at 5034, 874 m
at Hearne). A bulk sample mass of 1,028 kg (wet) was recovered at the drill at a
nominal bottom screen cut-off of 1.58 mm. Based on caliper measurements, a total
sample mass of 1,502 t was extracted.

In the winter of 2006 there was an unsuccessful LDD program
attempted at the 5034 North Lobe and at Tuzo. As a result of an unseasonably
warm winter that reduced the winter road availability, and difficult
geotechnical overburden conditions at the 5034 North Lobe, no casings were set,
and there was no recovery of kimberlite bulk samples. As a result, nine 610 mm
LDD holes (1,390.94 m), were drilled in 2008 to provide mini-bulk samples of the
Tuzo kimberlite (Table 11-6). A total of 1,234.14 m of kimberlite was
intersected, with a total sample mass, based on caliper measurements, of 956.2 t
at a nominal bottom screen cut-off of +1.5 mm. Total macro-diamond recovery was
1,713.2 carats.

**Drilling Contractors**

Drilling contractors used in the Gahcho Kué exploration and
delineation drilling programs are summarized in Table 11-7.

**11.4**

**Core and Cuttings
Logging**

GKJV field core logs recorded major kimberlite phases and
country rock intervals, total core recovery (TCR), rock quality designation
(RQD), intact rock strength classification (Brown, 1981), number of natural
fractures, number of mechanical fractures, and the nature of infill material.
Kimberlite intersections were logged by the consulting and project petrologists.

Typically for GKJV 1998 LDD drill holes, a drill log was
maintained for each borehole in which the hole number, depth, basic geology,
granite inclusion content, and details of samples taken were recorded
(Poniatowski and Hetman 1998). In addition, drill rig time-and-motion
operations, start and end dates, rate of penetration, and drill tool usage was
recorded. All LDD drill holes were caliper measured. A geological reference
sample was collected every 3 m.

Head-feed granulometry samples were collected on site, and
underflow samples were collected for micro-diamond investigation. A project
petrologist logged the RC drill chips.

The 1999, 2002, and 2003 LDD programs differed from the 1998
program only in that drill rig performance was recorded by noting depth, rate of
penetration, revolutions per minute, torque, pull-down and pull-back hydraulic
pressures, total weight on bit, and water usage. Geological reference samples
were collected on 1 m intervals. Head-feed granulometry samples were collected
and processed on-site with visual observations of sub-samples for chip shape,
relative hardness, and competency.

Collar
Surveys

During 1997 to 1998, drill hole collar positions were tied into
the UTM ground grid using a Trimble® 4800 series GPS. The LDD hole
collar locations for holes drilled in 1999 were established by measuring from
the grid (Williams, 1999). A contractor independently surveyed about 50% of the
collar positions (Valeriote, 1999).

In 2000, drill hole collar locations were determined using a
Trimble® PROXRS GPS that was post-processed (pseudo range).

The 2001 program LDD hole collars were located using Real Time
Kinematics GPS with the Leica® system 500 tied in to a local GPS
reference station; collars were re-surveyed after hole completion.

During the 2002 program, LDD hole locations were determined
using a Trimble® 5700 series system GPS in real time kinematics mode
tied in to a local base station receiver (Rikhotso, Williamson and Podolsky
2002). Hole collars were also re-surveyed after completion.

In 2003 core hole locations were determined using a Trimble® GeoXT GPS-enabled with a Wide Area Augmentation System (WAAS).  Locations were verified using a Garmin® 12XL handheld GPS.

Contractors (Sub-Arctic Surveys Ltd.; Hewlko, 2004) surveyed 2004 drill hole collars in CACS NAD 83 coordinate values with elevations in metres above sea level (masl). Hole collars were resurveyed upon hole completion. Sub-Arctic Surveys Ltd. are a
licensed survey firm in the Northwest Territories and have performed surveys for most of the exploration groups operating in arctic Canada.

11.6

Downhole Surveys

Single-shot downhole orientation surveys were performed on selected 19971998 core holes utilizing a Pajari® tool. Inclinations can be relied upon, but because this tool can be affected by magnetite in the rock (resulting from
serpentinization of olivine in kimberlite), azimuth data must be used with caution.

In 2001, inclined core holes were acid-tube surveyed, and the Hearne kimberlite delineation hole was down-hole surveyed by Reflex® tool. A Wellnav® gyroscopic survey was conducted on selected 2002 core holes (Rikhotso,
Williamson and Podolsky, 2002). In addition, one 2002 program three LDD hole cluster was Wellnav® gyroscope surveyed.

During the 20042008 programs, single-shot down-hole surveys were conducted along core holes typically every 21 m using a Reflex® EZ-Shot survey tool; tighter-spaced surveying was performed along upper parts of selected
holes, and less frequently for vertical holes.  Data noted on survey tickets were recorded.

Maxibor® downhole directional optical survey of selected core holes was conducted in 2006 as a QA/QC check of Reflex® EZ-Shot survey tool surveys.

11.7

Downhole Geophysics

Geophysical logging of 27 NQ core holes and 44 large-diameter holes was undertaken from December 1998 to April 1999, and included the following in-situ physical property measurements (Wallace, 1999):

- caliper (actual volume)
- density (mass calculations)
- magnetic susceptibility
- electrical conductivity
- natural gamma
- sonic velocity
- neutron activation.

The borehole physical rock property survey collected insitu (wet) bulk density data in each of the mini-bulk sample holes at a 5.0 cm sample spacing. The density probe contained a source of gamma radiation and a gamma ray detector. Calibration of
density probes is accomplished by correlating the counts per second (cps) returned by the instrument in large blocks of concrete or other material of known density. The correlation then allows cps to be converted to grams per cubic centimetre
(g/cm3).  These data were compared to data from nearby core holes determined by standard methods and found to be inaccurate; thus, these data were not used for Mineral Resource estimation.

11.8

Comment

LDD and LDC holes are well distributed aerially and vertically in each of the three main deposits  Hearne, 5034, and Tuzo. The results are believed by AMEC to be representative of the deposits.  The number of stones and total carat weight is
adequate to support diamond valuation and Mineral Resource estimation. Recovery of LDD cuttings was considered to be good but difficult to quantify because material smaller than the bottom screen size is lost during the screening process, and the
mass of the recovered sample (larger than the bottom screen size) is not an accurate indicator of recovery. Diamond breakage is a common problem with reverse circulation drilling, and this is discussed in Section 12.5.

5034 South, a relatively small pipe, could benefit from additional drilling to better define the limits of the body, whereas 5034 West and 5034 Centre could benefit from additional drilling to better define internal geology. All bodies remain open
at depth.

The amount of exploration drilling is consistent with known mineralogical, geochemical, and geophysical anomalies.  Core and cuttings logging is consistent with and typically exceeds industry-standard practices.  Collar surveys were performed using
industry-standard instruments and procedures. Downhole surveys were performed using industry-standard tools, but magnetic tools such as the Pajari®are not appropriate for these types of rocks because of the presence of magnetite in
kimberlite which may adversely affect the azimuth measurements. The other downhole tools are appropriate, and observed deviations are reasonable considering the rock types encountered. In general, deviations were minor, and AMEC believes that the
deviation surveys are adequate to support Mineral Resource estimation.

Geophysical surveys were appropriate for this type of deposit.

|12.1 | Small Diameter Core Sampling (Exploration, Delineation, and Geotechnical Drilling)

Exploration core drilling was performed from 1994 to 2003 to test geophysical and kimberlite indicator mineral anomalies and to delineate the kimberlite bodies discovered. These programs provided micro-diamonds for initial grade estimation.

Geology and Mineral Resource core drilling was conducted through 2007 to produce and improve geology and Mineral Resource models.  Pilot-hole core drilling in 2002, 2006, and 2007 was used for planning purposes in advance of proposed large diameter
RC mini-bulk sample drilling.

Ore dressing study (ODS), geotechnical, geohydrology, geothermal and civil engineering core drilling programs were conducted from 2004 to 2007 to support mine planning, engineering design, and to provide supporting environmental baseline data.

Core samples were utilized for:

- geology studies  slab and thin section analyses; petrology studies; whole rock chemistry; heavy mineral analysis; internal dilution estimation
- Mineral Resource estimation  density determinations; micro-diamond estimation
- geotechnical studies  slope stability analysis; rock-strength point-load and uniaxial compressive strength tests; concrete aggregate suitability; weathering and slake testing
- process plant design  ODS
- environmental baseline  acid rock drainage (ARD).

Prior to 2006-2007, micro-diamond samples were collected on variable sample lengths and avoided xenoliths in the sample. This effectively biased the overall grade higher than would be the case if the samples included the xenoliths which dilute the
material. Density samples were similarly collected on irregular intervals based on lithology.

A new micro-diamond, petrography and whole rock chemistry (WRC) core sampling methodology and quantitative geological data collection scheme was implemented in 2006 (Field and Ferreira, 2006; Kurzslaukis and Webb, 2006).  The new methodology allows
petrographic and WRC data to be related to micro-diamond data derived from samples that are collected according to a controlled consistent method and that have associated measured dilution data.  More reliable and realistic grade and waste control
models can be developed from these datasets, which reduces the risk and increases the confidence in subsequent Mineral Resource models based on the data.

The key sampling aspect is having a defined sample point located in the centre of a future mine bench. Hence the bench height, which is 12 m, controls the sample interval length. The mid-bench

sample point comprises both a
petrography and WRC
sample.The micro-diamond sample is taken directly adjacent to the centrally located petrography and WRC samples. In addition, the entire core is line-scanned in 1 m
intersections for waste control > 1 cm, and the micro-diamond intersections have independent, more detailed waste control scans. In summary, this line-scan methodology results in the quantification of the modal abundance of xenoliths exceeding 1

|       | The purpose of the 2007 summer large diameter core (LDC) program was to bring the 5034 North Lobe to Indicated status for revenue in order to improve confidence in the resource model for that unit. Data collection included
recording categorized real-time drill rig operations, time-and-motion activities, and geological logging. The core was processed, by lithological unit, through the Grand Prairie bulk sample plant for macro-diamond recovery. Sample intervals were
defined by lithological units and are variable in length. The main goal of this drilling program was to obtain a parcel of macro-diamonds to validate the diamond size distribution estimated using micro-diamonds. The parcel was compared on a
qualitative basis to macro stones in the East Lobe but the parcel was considered too small for diamond valuation purposes.

12.3.2

GKJV 1999 LDD Hole 311 mm RC Bulk Sampling Method and Approach

Williams (1999) reported the aims of the 1999 Gahcho Kué evaluation program were to conduct
a LDD RC bulk sampling exercise to define a global resource and partially delineate the pipes to 250 m depth. About 1,000 carats were required from each of the three highest-grade pipes (5034, Hearne and Tuzo) for diamond valuation.
The drilling objectives were to maximize sample recovery, and therefore diamond recovery, and to minimize diamond breakage by maximizing drill chip size.

Summary sample collection parameters were:

- 18 to 24 m
  sample interval relative to a 29 m sample datum below lake level
- 1.33 to 1.52 mm
  square mesh wire screen cloth at drill site; only oversize was collected
- wet samples
  weighed at drill scale
- security tags
  attached at drill site.

A nominal 1.4 mm screen aperture size with tolerances between 1.35 mm to 1.52 mm (Grenon et al., 1999) was employed at the drill site; only the oversize was collected.

Data collection included recording categorized real-time drill rig operations, time-and-motion activities, geological logging, head-feed granulometry, caliper and geophysical down-hole surveys.

GKJV 2001 LDD Hole 610 mm RC Bulk Sampling Method and Approach



GKJV decided to
employ 610 mm (24-inch) diameter RC drilling to recover mini-bulk samples in
2001. Summary sample collection parameters were:

- 6 to 12 m sample
  interval relative to a 29 m sample datum below lake level
- wet sample
  weighed at drill scale
- security tags
  attached at drill site
- the bottom
  screen cut-off at the drill rig was 1.58 mm and a nominal 1.5 mm bottom screen
  cut-off was employed during sample processing; only the oversize was
  collected.

Data collection included recording categorized
real-time drill rig operations, time-and-motion activities, geological logging,
head-feed granulometry and caliper logging.

|       | Small diameter core sampling has varied somewhat during the course of the program. Early in the program, samples were of variable length, and the procedure was to avoid contamination (crustal xenoliths) when sampling. This
produced micro-diamond grades that, while accurate for kimberlite, were biased high when dilution is incorporated. Procedures were changed in the 2006-2007 program to provide a constant sample length (12 m) and rigid sampling procedures. A
micro-diamond sample must incorporate all dilution. The changes to the protocol were justified, and AMEC believes that the changes have produced much better micro-diamond, lithological, and bulk density data.

Mini-bulk sampling procedures utilized for large diameter core (LDC) and large diameter RC (LDD) drilling are consistent with industry-standard procedures. The use of different bottom screen sizes has complicated interpretation of
the results, but this not viewed by AMEC as a significant issue. It has resulted in the need for additional data manipulation that can be avoided if a common screen size is utilized.

Density Data

12.4.1

Methodology



Density data were collected throughout the project. Canamera Geological and GKJV collected density data in the 1995-1996 and 1997-1998 programs. These data were based on water displacement methods and utilized core samples (Hira,
et al, 1998). These data were wet densities and were superseded by more recently collected data. In 1999, geophysical tools were used to collect density data. The data were found to be unusable for Mineral Resource estimation by Grieco (2008) and
have not been used. In 2002, GKJV again utilized core, but performed the density measurements by measuring the average length and diameter of the core, calculating volume, and determining the mass of the sample on a digital balance (Rikhotso,
Williamson and Podolsky, 2002). These data represent wet densities. Density determinations in the 2004 drill program utilized core; however, the method of determination was a coated immersion method followed by drying of the sample and reweighing.
This procedure provided both wet and dry density and is an industry-standard procedure (Waldegger, 2004a; Waldegger, 2005a).



A total of 104 density determinations were performed in 2005. Core samples 10 to 15 cm in length were selected at approximately 6 m intervals within kimberlite and 12 m intervals within country rock. Each sample was selected to be most representative of the local geology recovered in the core. Samples were collected
immediately at the drill site and wrapped in plastic to prevent moisture loss. In-situ (wet) and dry bulk density values were determined for each sample.



A total of 887 density determinations were performed in 2006 using the De Beers MRM protocol sampling methodology based Field and Ferreira (2006) and Kurszlaukis and Webb (2006). Core, 10 to 15 cm in length, was selected at 6 m
intervals within kimberlite and 12 m intervals within country rock. Each sample was selected to be most representative of the local geology recovered in the core. Samples were collected immediately at the drill site and wrapped in plastic to prevent
moisture loss. In-situ (wet) and dry bulk density values were determined for each sample collected using a standard, coated immersion method discussed in Waldegger (2004).

A total of 773 density determinations were performed in 2007
using procedures discussed above.

|       | Density values obtained in the early stages of the Gahcho Kué Project were largely wet densities. Those data were largely superseded by more recent dry density data, but were used, when no dry density data were available,
to estimate the dry density. The methodology used to estimate those densities is discussed in Grieco (2008).

There were 30 micro-diamond samples processed at the SGS Lakefield Research Laboratories, Ontario in 2002:

- 13 samples from the 5034 kimberlite
- 11 samples from the Hearne kimberlite
- 6 samples from the Tuzo kimberlite.

The diamonds and processed sample residues recovered at SGS Lakefield Research laboratories in 2002 were audited at the De Beers Kimberley Micro Diamond Laboratory in Kimberley, South Africa.

GKJV 2003 Micro-Diamonds

Micro-diamond samples were recovered from GKJVexploration core holes drilled in 2003 at the Kelvin and Faraday kimberlites, located about 7 to 12 km northeast of the Gahcho Kué kimberlite cluster.

GKJV 2004 Micro-Diamonds

There were a total of 32 micro-diamond samples collected from three core holes in 2004:

- MPV-04-234C (5034 East Lobe)  11 samples
- MPV-04-149C (5034 South)  15 samples
- MPV-04-121C (Hearne bridge zone between Hearne North and South Pipes)  6 samples.

Five micro-diamond samples from one 2002 Tuzo core hole, MPV-02-111C, were processed and audited in 2004. The micro-diamond samples selected were from between 93.5 to 300 m depth. The micro-diamond results were used to remodel grade and size
frequency distributions within the main Tuzo TK unit, to determine potential grade upside at depth.

The 5034 East Lobe samples collected in 2004 were processed in 2006.

GKJV 2005 Micro-Diamonds

Micro-diamond samples were collected from one 2005 hydrogeology core hole  MPV-05-239C (5034 North Lobe)  15 samples.

The 2005 micro-diamond samples were processed at the Saskatchewan Research Council (SRC) in 20062007 and incorporated in the 2008 grade model for the 5034 North-East Lobe (Ferreira, 2008).

GKJV 2006 Micro-Diamonds

In summary, 219 micro-diamond samples were collected along kimberlite intersections from 16 core holes drilled at the 5034 and Tuzo kimberlites during the 2006 Advanced Exploration program:

- 5034  9-holes: 174 samples
- Tuzo  7-holes: 45 samples.

The 2006 micro-diamond samples were processed over 2006-2007 and are incorporated in the 2008 5034 North-East Lobe and Tuzo grade model updates (Ferreira, 2008 and 2009).

GKJV 2007 Micro-Diamonds

A total of 472 micro-diamond samples were collected along kimberlite intersections from 32 core holes drilled at the Tuzo and 5034 East Lobe kimberlites during the 2007 Advanced Exploration program:

- Tuzo  27-holes: 364 samples
- 5034 East Lobe  5 holes: 108 samples.

The samples were processed over 20072008 and are incorporated in the 2008 5034 NorthEast Lobe and Tuzo resource grade model updates (Ferreira, 2008 and 2009).

Comment

The numbers of micro-diamond samples is appropriate for these deposits. Sample selection and lengths are appropriate. Table 12-1 summarizes the micro-diamond recovery programs by area and year.

12.5.2

Macro-Diamond Samples

The sample mass for all LDD holes was calculated from the density as determined by small diameter core holes and the diameter of the hole as determined by caliper measurements. Table 12-2 summarizes the macro-diamond recovery programs by area and
year.

Canamera Geological Ltd.  1996 Mini-Bulk Sample

In 1996 a 105.2 t mini-bulk sample of the 5034 kimberlite was obtained by PQ core drilling of 43 holes.  Material from 29 NQ delineation holes completed in 1996 contributed an additional 10.2 t to the mini-bulk sample.

Reportedly, a total of 252.4 carats were recovered from the 1996 Canamera Geological Ltd. PQ and NQ core mini-bulk sample of the 5034 kimberlite, averaging 0.065 carats/stone (Clement et al., 1996). Monopros Ltd. dispatched the Canamera 5034
diamonds to South Africa in April 1997 for valuation. Diamonds >0.07 carat were screened into sieve classes and individually valued at Harry Oppenheimer House in Kimberley, South Africa.  There were 784 stones weighing 164.61 carats valued at
$5,646.57 (about $34/carat).

1998 GKJV  140 mm (5.5 -inch) RC Mini-Bulk Sample Program

The 1998 GKJV 140 mm (5.5 -inch) diameter RC drilling program provided a mini-bulk sample of 222 t of kimberlite (calipered mass) from the Hearne, 5034, Tuzo, and Tesla kimberlites. Total program drilling was 72 holes for 7,197 m.

1999 GKJV  311 mm (12.25 -inch) RC Mini-Bulk Sample Program

There were 1,820.3 t of kimberlite, measured by caliper, removed from the 5034, Hearne, Tuzo, and Tesla bodies from 43 boreholes (Grenon et al., 1999).

Diamond breakage was of concern, as diamonds are believed to were broken during drilling, and from the relatively rapid ascent up the steel drill string and out of the recovery drop-out box. Significant diamond breakage (defined where > 5% of the
original diamond is lost due to fresh breakage) was variably reported for the different kimberlite varieties recognised in 1999:

- 5034  between about 17% to 64%: average of 43%
- Hearne  between about 22% to 47%: average 41% in HK and average 27% in TK.

Tuzo  between about 17% to 28%: average of 24%.The averages presented above represent the intervals where significant breakage was noted, not the amount of observed breakage.

2001 GKJV  610 mm (24-inch) RC Mini-Bulk Sample Program

The 2001 GKJV 610 mm (24-inch) LDD RC bulk sampling program recovered 968.5 t of kimberlite measured by caliper from seven LDD holes drilled in the 5034 and Hearne North kimberlites. The total interval of kimberlite sampled was 1,240 m. The bottom
screen cut-off at the drill rig was 1.58 mm.

The bulk sampling produced 19,842 stones, weighing 1,656.7 carats (0.083 carats/stone). A total of 5,337 diamonds from the 5034 and Hearne North kimberlites
were examined for

diamond breakage at the GSPS in Johannesburg, South Africa (SA) in 2001.
Of this, 3,240 stones were from the 5034 East Lobe (HK3 and HK5 units, 2000 model units) and 2,097 stones were from the Hearne HNTKN and HNTKNt units (Kelly, 2002).

For 5034, the diamond breakage levels ranged between 5% and 12% for an average of 7%. The breakage results for Hearne diamonds displayed low levels (between 4% and 9% for an average of 6%).

2002 GKJV  610 mm (24-inch) RC Mini-Bulk Sample Program

The 2002 GKJV 610 mm (24-inch) LDD mini-bulk sampling program achieved 11 holes:

| |  | 5034 West and Centre lobes  2 x 3-hole clusters     
| |  | -----------------------------------------------------
| |  | Hearne North  1 x 3-hole cluster, 2 x single holes).

A total caliper mass of 1,502.6 t was surveyed. The total interval of kimberlite sampled was 1,919 m.

The 2002 LDD mini-bulk sampling produced 24,705 stones weighing 2,386.0 carats (0.096 carats/stone). The 24,705 diamonds recovered from the Hearne and 5034 kimberlites from the 2002 mini-bulk sampling program were examined for fresh breakage by the
Harry Oppenheimer House Geology team, Kimberley, SA (Kelly, 2003).  The average 2002 LDD 610 mm LDD RC bulk sampling program diamond breakage levels were:

| |  | Hearne kimberlite  10%, ranging from 9% to 15%  
| |  | -------------------------------------------------
| |  | 5034 kimberlite  14%, ranging between 8% and 26%
| |  | Centre Lobe  averaged 24%

2007 GKJV Large Diameter Core (LDC) Mini-Bulk Sample

A LDC program to recover a targeted 100 carat macro-diamond parcel was conducted in the summer of 2007 at the 5034 North Lobe.  The nominal LDC diameter was 5.875-inches (149 mm). The summer of 2007 LDC program replaced the planned 2008 8-hole, 610
mm (24-inch) diameter LDD RC bulk sampling winter program when the geological
continuity of the 5034 North and East lobes was confirmed in the winter of 2007
(Sections 11.3.5 and 12.5.7).

There were five holes drilled totalling 1,341 m, for a recovered kimberlite core intersection of 638 m that produced 30.355 t of core processed.  There were also kimberlite chips from hammer drilling of kimberlite intersections recovered from
overburden casing operations totalling 57 m of which 45.4 m, 3.083 t was processed.

Summary macro-diamond results from the 2007 GKJV, 5034 North Lobe LDC program
are:

- Grand total of 103.775 carats recovered at an overall grade of 3.10 carats per ton (cpt) (including all incidental stones recovered at +1.0 mm), from 33.438 t of hammered cuttings and core).

In addition, there were 17.961 carats recovered, including incidental stones from 8.274 t of coarse core cuttings processed from two holes.

2008 GKJV  610 mm (24-inch) RC Mini-Bulk Sample Program

An LDD program to recover a targeted 1,500 carat macro diamond parcel was conducted in the winter of 2008 at the Tuzo pipe. The nominal LDD diameter was 24-inches (610 mm).

There were 9 holes drilled totalling 1,341 m for a kimberlite intersection of 1,234.14 m, that produced 956.2 t of measured mass and 565.3 t processed. In summary:

|
|
|

- a grand total of 1,713.2 carats were recovered including incidentals (20,968
stones)
- a total of 1,441.8 carats were recovered at a strict cut-off of 1.5 mm.

Comment

Macro-diamond sample numbers and the number of recovered stones are adequate to provide a reliable estimate of the numbers of stones and the value that can be expected from the various kimberlite units in the Gahcho Kué Project. Sample
lengths are appropriate and the methodology used to calculate the tonnages is consistent with industry best practices.

Diamond breakage studies have not been completed for the diamonds recovered from the 2007 LDC and 2008 LDD programs. AMEC recommends that those studies be completed.

|       | Kimberlite core with corresponding country rock contact
      zones were shipped to Yellowknife, Vancouver, Toronto, or Sudbury for
      detailed logging by project petrologists. Core was kept intact during
      collection at the drill sites and packed into labelled core boxes with
      depth markers placed between each drilled core run. Geotechnical logging
      was conducted at the drill sites. After detailed petrological logging was
      completed off-site, project petrologists selected samples for geology
      studies including slab and thin section analyses, petrological
      investigations, whole- rock chemistry, heavy-mineral analysis, and
      internal-dilution estimation.

logging of 5034 North Lobe LDD core determined geology units that were utilized for sample processing intervals. Sample processing was conducted at the De Beers plant in Grande Prairie, Alberta at 1.0 mm bottom cut-off, with a
primary crush at -12.0 mm, and secondary crush of the -12 +6.0 mm fraction at -6.0+1.0 mm (Skinner, 2007).

During 2008, the drilled Tuzo kimberlite intersection totalled 1,234.1 m in RC samples, and produced about 956.2 t as measured by caliper. A nominal 1.5 mm bottom screen cut-off was employed during sample processing that was
conducted at the De Beers Grande Prairie plant (Thomson, 2008). Drill holes were processed by individual bulk samples collected at 12 m bench intervals.

Mini-bulk sample preparation procedures are typical of the industry and are adequate to support Mineral Resource estimation.

13.3.1

Micro-Diamond Samples

Micro-diamond samples were processed at De Beers Kimberley South Africa micro-diamond laboratory (De Beers Kimberley), SGS Lakefield Research Laboratories (SGS) and at the Saskatchewan Research Council (SRC) Geoanalytical
Laboratories. Selected micro-diamond and residue samples recovered at SGS and SRC have undergone audits at the De Beers Kimberley Micro-diamond Laboratory as part of routine quality assurance and quality control (QA/QC) measures.

The following discussion of micro-diamond processing is based on a visit by AMEC to the Saskatchewan Research Council micro-Diamond recovery facility in Saskatoon, Saskatchewan. Figure 13-1 is a generic micro-diamond recovery flow
sheet.

Sample Receiving and Preparation

Kimberlite samples are received by the laboratory, sorted, and assigned laboratory sample numbers. The samples are logged into the laboratory information system (LIMS) and are dried for 1216 hours at 60oC. The
samples are crushed, if necessary, to about -1/2 inch and split into 8 kg aliquots. The samples are removed from the oven and allowed to cool.

Caustic Fusion
Processing

The caustic fusion process begins with
placing 75 kg of virgin caustic (NaOH) in an approximately 40 l furnace pot.
The 8 kg sample is then loaded on top of the caustic. Bright yellow synthetic
diamonds, 150-212 μm in diameter are loaded on top of the kimberlite sample as a
spike.

The temperature is then ramped up to
550o C, and the sample is held at that temperature for 40 hours.
After 40 hours, the pots are removed from the kilns and allowed to cool. The
molten sample is then poured through a 75 μm screen. (These screens are
single-use screens that are discarded after use.) Micro diamonds and insoluble
minerals remain on top of the screen. Insoluble minerals are typically ilmenite
and chromite. The pot is then thoroughly soaked with water to remove any
remaining caustic and trapped diamonds and the water is again poured through the
screen.

Because not all of the material
dissolves, additional steps are required to clean ilmenite, chromite, and other
materials from the concentrate. Samples are sent to the wet lab where acid is
added to neutralize the solution. The residue is then rinsed and treated with
acid to dissolve readily soluble materials from the residue.

The sample is transferred to a
zirconium crucible along with an additional bright yellow synthetic tracer
diamonds and fused with sodium peroxide to remove any remaining minerals other
than diamond from the sample. The sample is allowed to completely cool, and the
liquid is decanted from the beaker. The remaining residue is then wet screened
to divide the recovered diamonds into micro-diamond size classes. Stones are
stored in plastic vials containing methanol.

Sample Picking, Weighing, and
Data Recordation

Samples are then sent to the
observation room where they are hand picked by trained observers. Spikes are
recovered first. After spike recovery is deemed complete, diamonds are picked
from the residue and individually weighed. The weight of each stone in each size
class is recorded. (In GKJVs case, stones smaller than 300 μm are not
individually weighed, but the total parcel in each size class is weighed.)

Stones are weighed on ultra-micro
balances capable of accurately weighing 75 μg. Data are recorded on paper that
is then manually entered into a spreadsheet by trained clerical personnel.

Comments

The laboratory is ISO 17025 accredited
for micro-diamond work.

The laboratory reportedly has an
average recovery efficiency of 98% based on spike recovery. Less than 70%
recovery results in the laboratory absorbing the cost of the analysis and

Quality control (QC) consists of:

| |  | every sample is picked by a designated observer, and the residue is
  repacked by a senior observer to insure that no diamonds were missed. The
  senior observer then signs off on the sample

| |  | new observers are introduced to the process by picking tracer diamonds for
  two to three weeks. They are supervised very closely for as long as four
  months. After that, normal QC procedures apply.

Due to the number of container
transfers (7), screenings (2), and general handling of the samples, there is a
very large risk of losing stones. It was obvious that the laboratory personnel
are acutely aware of this and that numerous procedures are in place to minimize
the possibility of lost stones.

In AMECs opinion, the procedures are
appropriate.

Sample processing during 1999 was by
gravity feed from the sample bag through a scrubber fitted with 12.5 mm square
aperture a trommel screen, all +12.5 mm material was crushed to 10 mm and fed
back into the scrubber. All -12.5 mm to 1.6 mm material was fed via a dropout
  box onto a 1.6 mm square aperture poly-panel pre-preparation screen, where
  this DMS feed was washed. Following preparation, the sample was gravity fed into the mixing box from where the FeSi/sample mix was pumped through a 200 mm
diameter cyclone with a 46 mm spigot.

13.4.2

20012008 Grande Prairie Dense Media Separation (DMS) Circuit

A purpose-built 5 t/h (200 mm cyclone) DMS plant, with an integral scrubber, trommel screen, crusher, preparation screen and concentrate recovery system was installed at De Beers processing facility in Grande Prairie,
Alberta and used in 2001.

The sample material was gravity fed from the 2-ton sample bag into a 2-ton feed bin; from the feed bin the sample was fed onto a 9 m long feed-belt; feed speed was controlled by a gate in the front of the conveyor feed tray. From
the conveyor, the material was gravity-fed into the scrubber, with the assistance of the crusher pump water. After scrubbing, the sample was discharged through a 14 mm trommel screen into a 4/3 Warman pump. This material was fed via the 4/3 Warman
pump through a drop-out box onto the prep screen on the DMS unit. Material over 14 mm in size fell from the trommel screen lip into a 6 x 4 Masco jaw crusher, set to a 10 mm closed-gap setting. This crushed product was gravity fed into a 3/2 Warman
pump and returned to the scrubber. In this way the circulating +14 mm oversize material remained in closed circuit until reduced to below 14 mm in size. Due to the minimal amount of +14 mm material present in the samples, the jaw crusher could not
be choke-fed during production; however, most of the oversize material preferentially, remained inside the scrubber during feeding. This material was choke-fed through the crusher when the scrubber was reversed during clean-out at the end of
treatment of each sample.

During processing, fines (-1.5 mm material) are removed on the preparation screen, while the sample material is split into high- and low-density components in the cyclone. Sample concentrate reports to pails within a concentrate
cage, and tails are collected in a per- numbered sample bag and stored on a per-sample basis. The single deck prep screen is fitted with 1.6 mm square aperture poly-panel screen panels and a set of spray bars. After washing on the prep screen, the
sample material is gravity fed into the DMS mixing box, where the sample material is mixed with the dense medium (270D grade ferrosilicon (FeSi) and water mix). This mixture is pump-fed at a pressure of ~98 Kpa into a 200 mm DMS cyclone with a 46 mm
spigot. Lights (sample tailings) from the cyclone are drained and washed across the lower deck of a double deck product screen to recover FeSi and discharged to a bulk-sample bag for weighing and storage. Spigot product from the cyclone (DMS
concentrate) is similarly washed across the upper deck of the double deck product screen (1 mm square poly-panel) and gravity fed to a 20 litre concentrate pail, located within a secure cage.

DMS concentrates are collected into a pail within a cage that is secured by two padlocks and two single-use security seals. The pail is sealed while inside the glove-box equipped concentrate cage, before being removed from the
cage and weighed. These concentrate drums were all sealed with uniquely numbered security seals and were then stored in a locked transport container prior to shipment.

A video camera was installed inside the
transport container (which was also alarmed), and two cameras overlooked the
treatment plant concentrate cage. Two seals, as well as two padlocks, seal both
the cage and transport container. The plant supervisor and the operator each
held a key to one of these padlocks; consequently neither the cage nor the
concentrate container could be opened without both the plant supervisor and the
operator being in attendance.

Prior to export, concentrate pails were
drained of water, weighed, and boxed within a palletized wooden crate, which was
firmly screwed together and then strapped using metal bands. Uniquely numbered,
tamper-evident seals were strategically placed on these straps to detect
unauthorized opening the crates. Sample shipments were made on a regular basis.
Shipments would be collected from the Grande Prairie premises by a Brinks Inc.
armoured vehicle and driven with an armed escort, to the Edmonton airport, where
they were air-freighted to Johannesburg via London.

Following DMS concentration, an overall
concentrate percentage yield (concentrate mass divided by sample mass calculated
from caliper measurements of hole diameter) was recorded. An overall sample
recovery was calculated by dividing the headfeed sample mass by the sample mass
calculated from caliper measurements of the hole diameter. All samples were
subjected to similar processing, except for clay-rich samples, where small clay
balls could still be found in the tailings following treatment. Such samples
were re-processed.

Other measurements recorded during
processing include: moisture content and representative screening analysis of
the tailings material. The treatment plants operational parameters were
recorded. This included measurement of operational time-and-motion information
with discrimination of operational activities and downtime. Medium density was
recorded regularly as was the operating-medium pressure at the cyclone. Testing
with density tracers was routinely undertaken, and the density cut-point and
probable error (Ep) were determined.

Various measures were implemented to
prevent sample contamination. The plant was cleaned after every sample. This
involved a thorough cleaning of the scrubber, feed bin, pumps, screens, etc. A
more thorough clean-out and a clean-up procedure was followed between processing
material from the different kimberlite pipes.

In an attempt to avoid contamination,
the scrubber was reversed and pressure-washed. Spillage was collected from
beneath the plant and re-introduced into the process stream. All screens were
hosed and unblinded between samples. The cyclone-feed pump would be stopped and
restarted, to dislodge any trapped grains. The plant was operated without load
for 15 minutes between samples in order to flush out any entrained material, in
an attempt to prevent contamination between samples.

Macro-diamond sample preparation and
recovery was performed using industry-standard procedures. The resultant diamond
populations are adequate for Mineral Resource estimation and mine planning.

|       | A surface grid tied to the Universal Transverse Mercator (UTM) system was established in the winters of 1997 and 1998 over each of the kimberlites. Several permanent reference points in each grid were established on land using the
Trimble 4800 series global positioning system (GPS). These reference points were re-occupied later that year, again with a Trimble 4800 series GPS, which confirmed the accuracy of the original locations (Hodgkinson, 1998).

|       | The coordinate grid established in 1997-1998 was re-established from previously laid-out permanent markers using a Trimble 4800 Series GPS system. The LDD hole collar locations were all established by measuring from the grid

query builder function. Hole collar
survey, drilling (core and large diameter), geological and geotechnical logging,
sample collection and consignment information were captured. The system has an
open structure in that remotely-entered field data were copied onto a Microsoft
SQL server central database in Johannesburg, South Africa.

The Mineral Resource Sampling Database
(MinSAMP) model is a generic, advanced diamond sampling workflow-based
repository capable of storing all sample-related data. The current Gahcho Kué
Project MinSAMP model stores 20072008 collar survey, drilling (core and large
diameter drilling), geological and geotechnical logging, sample collection and
consignment, sample processing and plant configuration, diamond sorting and
consignment data. The model consists of several groups of tables and views named
according to the workflow process or type of data they contain. The MinSAMP
database is currently running on a Microsoft SQL®server located in
the De Beers Toronto office. Databases from pre-2007 drilling programs are being
migrated into MinSAMP.

All DBCKPU petrological data, such as
geology logs, line scan, photographs, whole-rock chemistry, micro-diamonds,
maps, cross sections, consignment, tables and scorecards, and general
communications, are currently saved on a central server at De Beers Toronto
office. These data are being migrated into MinSAMP for GKJV.

The Gahcho Kué kimberlites are modeled
in three dimensions (3D) using Gemcom® software. Waldegger (2005b)
reported that the first 3D model was completed in 1998 and that subsequent
iterations were completed in 1999, and 2002. The current Gemcom®
model iteration of the Hearne kimberlite was completed in 2005. The 5034 and
Tuzo kimberlite Gemcom® models were completed in 20072008. All the
final interpreted data from drilling and mapping used in both the country rock
and kimberlite modeling are stored in an Access®database.

The database was internally audited
during April to July 2004. Line verification was undertaken on collar location,
downhole survey data, geological logs and macro-diamond data. Drill hole folders
were compiled for the Gahcho Kué data room in conjunction with the audit. A
major restructuring of the Gemcom® project and associated database
was completed by the project resource geologist (Waldegger, 2005b).

Hard copy exploration and advanced
evaluation geologyMineral Resource estimate data including drilling program
reports and individual drill hole files were compiled. The hard copy drill hole
reports correspond to the drill holes in the Gemcom® database. The
hard copy reports are filed and indexed in the geology and resource data room at
the Gahcho Kué Project office in Yellowknife. The geology and resource data room
files are also digitally copied and stored in a project Electronic Data
Management System on a central server at De Beers Toronto office.

AMEC and its precursor MRDI, audited
the database in 1999, 2003, 2005, 2007, and 2008 and found no significant errors
or omissions.

AMEC believes that the database is
adequate to support Mineral Resource estimation. Routine backups, integrity
checks and audits minimize the likelihood of significant numbers of errors
finding their way into the database.

Sample
      Security

Security procedures were in place
during bulk and mini-bulk sampling drilling programs at the Gahcho Kué site,
during sample processing at the De Beers DMS facility in Grande Prairie; during
diamond recovery at the De Beers Group Exploration Macro-Diamond Laboratory
(GEMDL) in Johannesburg, RSA and at the Saskatchewan Research Council
Geoanalytical Laboratories.

The purpose of security procedures at
the Gahcho Kué site was to set out the security duties, transportation and
chain-of-custody processes around the handling, storage, documentation and
overall security for the bulk sampling programs. Independent security
contractors were employed at the Gahcho Kué site for the 2001, 2002, and 2008
large-diameter drill hole RC bulk sampling programs.

Mini-bulk samples collected during LDD
RC programs were secured in closed bags with uniquely numbered single-use
security seals at the Gahcho Kué site. The chain-of-custody was maintained
through a series of consignment document sign-offs and tracking of the sample
and security seal numbers from the initial collection of the sample, during
transportation and to the final processing stages. Field consignment records of
the bag and seal number, bag weight and condition were documented.

The mini-bulk samples were transported
directly from Gahcho Kué to Grande Prairie in vans that were padlocked and
affixed with uniquely numbered security tags via winter ice roads when possible,
or flown by commercial aircraft to Yellowknife and then transferred to closed
vans for shipment to Grande Prairie.

The De Beers Grande Prairie bulk sample
DMS processing warehouse is a locked facility, monitored by multi-camera video
surveillance by contracted security personnel. DMS concentrate is fed into a
pail within a locked cage. Once a sample is completed the pail is sealed using a
glove-box arrangement. Concentrate cages and storage areas are double sealed and
locked, requiring the presence of one senior GKJV person and one contracted
security personnel for access. Records are kept of visitors to the facility. DMS
concentrates are locked into sealed 20-litre containers, each of which has a
uniquely numbered, single-use seal affixed. These containers are stored inside a
class-three demountable vault until periodic shipments are made to Johannesburg
using a security contractor.

At the Saskatchewan Research Council
Geoanalytical Laboratory macro-diamond recovery facility, GKJV security staff
reviewed the security procedures and systems and made recommendations for
improved camera surveillance and hands-off macro-diamond sorting by glove box.
The recommendations were implemented.

The De Beers GEMDL facility in Johannesburg conforms to all the De Beers Diamond Control Teams requirements for the secure processing of diamondiferous material.  This involves access control, surveillance, hands-off processing and diamond
control in accordance with the South African Diamond Act No. 56/86.  AMEC believes that the security measures for the Gahcho Kué Project were adequate.

This work resulted in De Beers joining the project in 1997.

GKJV (19972004)

SRK Consulting conducted three quality assurance exercises during the 19981999 Monopros Ltd. geotechnical program (Eichenberg, 1999), covering:

| |  | hole collar locations and drill rig setup           
| |  | ----------------------------------------------------
| |  | core orientation (Pajari®tool and acid-test surveys)
| |  | geotechnical measurements.                          

A senior De Beers petrologist from the Kimberley, SA, De Beers Geology Division, peer reviewed De Beers Canada Kimberlite Petrology Unit (DBC-KPU) work on the Gahcho Kué project in behalf of GKJV in 2000. This involved inspection and
verification of the 1999 Gahcho Kué core, polished core specimens, and core thin-section samples described and logged by the DBC-KPU petrologists.

The De Beers MRM Group Resource Petrologist performed a peer review of the Gahcho Kué resource geology data with GKJV project petrologists and resource geologists during July 2004 at the Gahcho Kué Project workplace within AMEC
Vancouver, BC offices (Stiefenhofer, 2004).

A peer review of the 5034, Hearne, and Tuzo kimberlites three dimensional geology models constructed using Gemcom® modelling software, was conducted by the MRM Group Resource Modelling Manager, together with the project resource
geologist (Farrow, 2004). The output was an updated geology table and geology models reported to De Beers Mineral Resource Management (MRM) group standards to enable completion of the internal audit (Waldegger, 2005b).

The geology of the pipes within the Gahcho Kué kimberlite field was published repeatedly in peer-reviewed international journals (Hetman et al., 2004; Kurszlaukis and Lorenz, 2008; Rikhotso et al., 2003) and presented at international
conferences such as the Eighth Kimberlite Conference (Victoria, 2003), 2nd International Maar Conference (Hungary, 2004), and the International Kimberlite emplacement workshop (Saskatoon, 2006).

The De Beers Kimberlite Petrology Unit and its work on Gahcho Kué kimberlites in behalf of GKJV was repeatedly and successfully peer reviewed and audited during 2007.  De Beers internal auditors were Matthew Field and Dr. Johann
Stiefenhofer (Stiefenhofer, 2007). Prof. James White (Dunedin University, New Zealand) is an internationally-acknowledged specialist on maar-diatreme volcanism and peperites and was an external auditor (White, 2007).

Dr. Kurszlaukis has published general papers on the geology of kimberlite and carbonatite root zones in international peer-reviewed journals (Lorenz and Kurszlaukis, 1997, 2007; Kurszlaukis and Lorenz, 2008).

2005 Desktop Study Report Data Verification

An internal audit of the GKJV Gemcom® database was conducted during April to July 2004 (Pizzolato, 2004a and b).  Of the various data sets that exist in Gemcom®, the sets that underwent line verification against De
Beers evaluation database records were:

| |  | collar location      
| |  | ---------------------
| |  | down-hole survey data
| |  | geological logs      
| |  | macro-diamond data.  

Drill hole folders were compiled for the Gahcho Kué data room in conjunction with the De Beers Gemcom® internal audit.

It was stated in the 2005 Desktop Study Report that continual GKJV database integrity checks are embedded in:

| |  | prospecting samples database  project allocation, sample number, location; visual results, probe results                                                                                                                                      
| |  | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
| |  | sample consignments database  country of origin, consignment number, sample listing, sample location, laboratory, project allocation, sample type, number of samples, sample size, weight, shipment date, processing required, waybill number.
|
|
|
|
|

In addition, manual data reviews were performed on results received for:

| |  | micro-diamond samples (in database entry)  consignment number and sample listing; sample location, sample type                                                   
| |  | ------------------------------------------------------------------------------------------------------------------------------------------------------------------
| |  | macro-diamond samples (in Gemcom®entry)  consignment number and sample listing, sample location, sample type, sieve class totals for number of stones and carats.

The >0.07 carat diamonds received from Canamera in 1997, recovered from the 5034 kimberlite mini-bulk sample collected in 1996, were reconciled by Chinn (2003). The number of stones present and their carat weights were compared with the available
hard copy and electronic records. The <0.07 carat stones were not audited, and were sent to the KMDL, SA for storage. Chinn (2003) reported that the hard copy and electronic versions were not always in agreement with the >0.07 ct stones
received.

Brown (2004) reported the update to the Gemcom® geological and resource block models following the changes from the 2004 Advanced Exploration drilling program. As the changes to the geological model were only minor modifications to
the orebody envelopes, the Mineral Resource was updated using the 2003 Mineral Resource parameters (Gordon-Coker and Bush, 2003).

A strategic geotechnical and geohydrology mine planning review by GKJV, SRK, and HCI, and an independent geotechnical consultant from CSIRO Exploration and Mining, was held at SRKs Vancouver, BC offices between 30 September and 1 October 2004.
Recommendations for future work were made (Monthly Report Gahcho Kué Diamond Project October 2004):

| |  | additional pit geotechnical core holes at Tuzo (3-holes, about 750 m), 5034 North Lobe  Tuzo (1-hole, about 250 m), Hearne South gravity structure (1 hole, 250 m) were recommended for drilling in the winter of 20052006
| |  | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
| |  | additional deep geohydrology core holes for environmental baseline conductivity and water chemistry were recommended for the summer of 2005 (5 holes, about 2,000 m).                                                       

Subsequently, external peer review of representative 2004 pit geotechnical core intersections was carried out in Yellowknife, NWT by a consultant from CSIRO Exploration and Mining (Australia), during 4 to 5 October 2005 (Read, 2004).  Read (2004)
reported that pit-slope design recommended by SRK is consistent with the site geology and ongoing levels of conceptual mining studies.

|     | An external audit of the procedures of the 1999
      evaluation program at Kennady Lake was performed by a geologist and
      geostatistician from MRDI (now AMEC), during a site visit lasting six days
      from 10 to 16 February 1999. Recommendations for improvements were
      implemented (Williams, 1999). Similar audits were undertaken at the
      Monopros Ltd. Grande Prairie, Alberta, bulk sample processing plant and
      the Geological Sample Processing Services (GSPS) diamond recovery plant in
      Johannesburg.

The aim of this 10% external audit was to evaluate the suitability of the Gemcom® database for its use in Mineral Resource estimation in compliance with NI 43-101 regulations.  Shahkar (2005) concluded that although the overall 2%
database error was technically a high error rate, the majority of these errors could be remedied with more stringent database management practices and record keeping. The nature and generally small magnitude of the errors found led AMEC to conclude
that their overall impact on the Mineral Resource model would likely not be significant.

AMEC (2007)

During OctoberNovember 2007, a review of the 2007 project database was undertaken:

| |  | A review of the De Beers Gemcom®database was performed. Data were compared to original records to check for accuracy of transcription. AMEC compared approximately 10% of the data, including drill hole collar location, sample
intervals, diamond recoveries, density measurements and drill hole intercepts to original records. Less than 1% of these data were found to be in error, and AMEC therefore considered the 2007 database adequately accurate to support resource
estimation work.
| |  | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
| |  | AMEC reviewed the solid models present in the database for
three kimberlite bodies, 5034, Hearne and Tuzo. These models were reviewed in
section and plan views and compared with logged drill hole lithologies. The
Hearne and 5034 models were found to be generally adequate. The interpretation
for Tuzo was recommended for review.                                                                                                                                                          
| |  | A review of the diamond valuation methodology including size-frequency distribution determinations was performed. AMEC concluded that the valuation methodology was standard for De Beers and acceptable.                                                                                                                                                                                                                                                                                         
| |  | AMEC noted that all Mineral Resource estimation work was completed at Mineral Resource Management (MRM) in Johannesburg, South Africa using Isatis®software. This required all solids models and the underlying database to be
transferred from Gemcom®to Isatis®. Review of the two databases indicated that they were not always synchronized. Minor discrepancies between the two databases were noted and resolved.                                                                           
| |  | AMEC reviewed the resource calculation methodology, adjustments to stone size- frequency, valuation modelling for each kimberlite cluster, and inclusion of incidental diamonds in the 2003 Mineral Resource estimates for 5034 and Tuzo, and was of the
opinion that the grade and tonnage results reflect a conservative estimate of the economically viable diamond content of the Gahcho Kué kimberlite bodies.                                                                               

AMEC concluded that the 2003 Mineral Resource
estimate was conservative and, in general completed within industry best
practice guidelines

AMEC (2009)

As part of the review for this Report,
AMEC audited the 2004-2007 geological database, reviewed geological logging
procedures, reviewed petrological procedures used to determine final rock types,
reviewed the geological models for conformance with the drill information,
reviewed the resource estimation procedures and assumptions, and resource
classification. No significant errors or omissions were noted in the database.
Drill logging and petrological procedures meet and generally significantly
exceed industry-standard best practices. The geological models conform to the
geological data. Estimation practices and assumptions are reasonable. Resource
classification is reasonable. Many of these aspects of this review are discussed
in Section 17.

AMEC also visited the Saskatchewan
Research Councils micro-diamond recovery laboratory and reviewed the procedures
used to extract, classify, and weigh micro-diamonds. No issues of concern were
discovered during this review.

AMEC was supplied with a valuation from
the Diamond Trading Company (DTC). The QPs believe it is appropriate to rely on
De Beers valuations, as the DTC is the rough diamond distribution arm of the De
Beers Family of Companies and is the world's largest supplier of rough diamonds,
handling nearly half of the world's supply by value. The DTC is a centralized
group containing the only personnel within DeBeers that are qualified to perform
diamond valuations. All valuations utilized by the DeBeers operations as well as
evaluation groups are performed by the DTC. The DTC is the recognized originator
of the methods in use by all valuators.

A valuation was performed on behalf of
MPV by WWW Diamond Consultants International (WWW) of London, to obtain
valuations and perform price modelling, and this valuation was supplied by MPV
to AMEC. The QPs believe it is appropriate to rely on the WWW valuations, as WWW
are recognized international leaders in this field, and are the valuers to the
Federal Government of Canada for the Canadian diamond mines in the Northwest
Territories

Mr. Martinus Oosterveld assisted AMEC
by providing a comparison between the De Beers and WWW diamond value estimates.
Mr Oosterveld is regarded as one of the leading authorities in diamond resource
evaluation and diamond geostatistics. He has more than 30 years of experience in
diamond mine development, including nearly a decade as Ore Evaluation Consultant
to De Beers Consolidated Mines Limited and Anglo American plc, involved in
evaluating all of De Beers diamond properties worldwide, and an additional 15
years of experience as an independent diamond resource consultant based in South
Africa.

|14.6.1 | Diamond Valuations
|------ | ------------------
|       |                   

The Qualified Persons are not able to
apply quality control measures to the valuation process performed by either De
Beers or WWW International.

The reason for this is that diamond
valuation is, at best, only partially analytical (in the way that a gold assay
process can be termed analytical), as the diamonds are sieved and subjectively
classified by colour, clarity, etc. The dollar per carat determinations for
various stones, however, is ultimately governed by the valuators price-book.
This part of the process is proprietary, governed by a given valuators view of
the marketplace and can vary from valuator to valuator, particularly for larger
stones. Even in larger parcels, valuators must then model or extrapolate
values in the larger stone size classes where there may be few representatives.
The methodology for modelling is also proprietary.

These diamond valuation procedures do
not lend themselves to quality control measures that a qualified person could
apply as with a commercial assay laboratory. At every step, the QPs are relying
on the valuators opinions of the diamond market and their subjective view of
diamond values.

The Qualified Persons also rely on the
valuators models which are heavily dependent on their view of the diamond
market, their proprietary estimates of the likelihood of finding larger stones
in the deposit because of sample-size support, and the perceived value of those
larger stones.

The culmination of the process is the
average prices for given zones, lobes or pipes. The heavy dependence of the
process on economic market assessments, and the proprietary nature of the
valuators assumptions and methods, materially affects the quality of, and
confidence in, the Mineral Resource estimate. In this way, the valuations used
in the Mineral Resource assessments are markedly different than the concept of
analytical mineral assays in, for instance, a precious metal project. The
proprietary nature of the processes employed for valuations limit any
quantitative assessment of the added risk to the project. Other than reviewing
the De Beers data and the WWW report for transcription errors in the transfer
of the valuation figures into the database, no other data verification
procedures can be applied.

Diamond valuators are experts, but not
Qualified Persons, and and the Qualified Persons preparing the Mineral Resource
estimates and assessing the reasonable prospects for economic extraction have
had to completely rely on the De Beers and WWW diamond values provided.

There are no advanced-stage diamond
properties adjacent to the Gahcho Kué Project. Three currently-producing diamond
mines are located in the NWT, north of the Project: Ekati (BHPBilliton Ltd),
Diavik (Rio Tinto plc) and Snap Lake (De Beers).

|       | Preliminary data from both the ore dressing studies (ODS)
      and the LDD chip processing indicated that the kimberlite has a low DMS
      yield that should result in easy DMS operations and a relatively small
      recovery plant. The fines content presented in Table 16-2 is the total
      amount of fines produced during both drilling and scrubbing operations. As
      such, this is not considered representative of the fines that would be

|       | Information relating to the X-ray properties of diamonds
      was available from the evaluation programs and from the 2002 ODS. The ODS
      included magnetic susceptibility testing of the diamonds and gangue and
      the development of a luminescent profile of the gangue material. The
      recoverability of diamonds by X-ray sorting based on stones recovered
      during the evaluation programs, is summarized in Table 16-3. The number of
      stones larger than diamond sieve #12 was small, and the results were
      therefore biased toward the luminescence intensity (LI) values of the
      small stones. Generally, the large stones (>#12) showed good
      luminescence, while the smaller ones were more problematic. Recovery of
      small sizes would require very sensitive diamond sorting equipment, that
      is, the X-ray sorting equipment will need to be set at a lower than normal
      threshold setting.

Note: The 0.25 V is a threshold setting
on a X-ray machine. When a diamond luminesces, the light is converted to an
electrical signal, and if the signal is above 0.25 V the machine will eject the
diamond and surrounding particles to the concentrate chute.

Luminescence data obtained for the
gangue material show that high yields can be expected when X-ray recovery
technology is used to process DMS concentrate. Yields for the finer size
fractions are estimated to be in the order of 0.3%. Excessively high yields can
be expected for the coarser size fractions (+8 mm material.) The data also
showed that a yield in excess of 44% could be expected when processing material
from certain areas of the kimberlite pipes

All the diamonds have a magnetic
susceptibility less than 20 x 10-6 cm3 and could thus be
recovered using high intensity magnetic separation. Magnetic susceptibility
results showed that of the diamonds tested, 13% were diamagnetic and would not
be recovered in using high intensity magnetic separation; thus other methods are
required to recover those stones. With the use of an NdFeB magnet, gangue mass
reductions of up to 81.95% were measured.

| |  | DMS yields should be relatively low, potentially less than 1%, for both
  5034 and Hearne kimberlite bodies. The optimum split size based purely on the
  lowest calculated yield was found to be 8 mm. A split DMS was recommended for
  the conceptual Gahcho Kué process flowsheet.                                                                                                                                   
| |  | Co-thickening has benefit in terms of reagent consumption, water savings
  and generation of high-density slurry. A high density thickening unit with
  picket rakes would be necessary to assist with the compaction of the mud-bed
  to achieve higher-density slurry.                                                                                                                                                 
| |  | The results from the ore dressing study showed that the Gahcho Kué
  material is similar to other kimberlites processed in Southern Africa with
  respect to comminution and densimetric profiling.                                                                                                                                                                                                                      
| |  | Normal wear rates are expected for the processing of the Gahcho Kué
  material through standard diamond processing comminution devices such as cone
  and high pressure roll crushers. DMS yields can be classed as medium to low
  with less than 1% yield being obtained for both the 5034 and Hearne
  kimberlites.                                                                                                 
| |  | One problematic area that was identified by the ore dressing study was the
  large amount of luminescent material that reported to the DMS sinks fraction.
  This material was subsequently tested on a dual-wavelength X-ray machine to
  determine the probable yields that could be obtained from a production unit.
  Initial indications were that up to 90% of the luminescent gangue material
  could be rejected.
| |  | High flocculant consumption rates were obtained for treatment of slimes
  where the grit fraction had been removed. Flocculant consumption for
  co-thickened slurries were approximately half that of the slimes only
  fraction.

| | The conceptual recovery plant designed in 2006 was based on
grease recovery for -6 mm material and X-ray recovery for +6 mm material. To
remove non-diamond material, degreased -6 mm concentrate was proposed to be
chemically treated using hot molten caustic, and +6 mm X-ray concentrate to be
hand-sorted.

Additional conceptual studies and
metallurgical testwork are ongoing and include plant layout design and
considerations, recovery and thickener testwork, mass and water balance
considerations, and, potentially, dynamic simulation studies to determine the
plant capacity based on variations in operating rates of selected equipment and
surge capacities.

AMEC believes that the amount and types
of metallurgical testwork performed to date is appropriate for the project and
is adequate to support Mineral Resource estimation.

|17.1 | Introduction                                      

The following section summarizes the
Mineral Resource estimation techniques used to evaluate the Gahcho Kué
kimberlite bodies. Final results and resource classification for the April 2009
Gahcho Kué resource model are reported.

Section 17.1 presents a brief
introduction and overview. Section 17.2 discusses the Mineral Resource estimates
for the various pipes and lobes at Gahcho Kué. In each case there is a
summarized section on the geologic models as they relate to the Mineral Resource
estimation process. These summaries should not be seen as a comprehensive
geological discussion of the deposit areas. A more rigorous geologic treatment
can be found in Section 7.3. Following the geological model sub-section,
discussions of grade estimation for each sub-area appear sequentially. Section
17.3 summarizes the Mineral Resource classification and assumptions used to
support the reasonable expectation of economic extraction necessary for Mineral
Resource declaration. Section 17.4 presents Mineral Resource estimate
tabulations.

The databases were constructed and
maintained in the Gemcom® modelling system. Geological models were
constructed using Gemcom® modelling tools. Mineral Resource
estimations were carried out in both Gemcom® software and
Isatis®. Open-pit shells for use in resource declaration were
developed in Whittle®using the Lerchs-Grossman open-pit optimization
algorithm.

LDD was used to collect samples of
kimberlite for grade and diamond value modelling. Macro-diamonds4
from the LDD were used to estimate local grades on 5034 West and Centre Lobes
and Hearne Pipe. Grade estimations for these pipes were completed using
variography and kriging methods. Diamonds from this drilling were also used to
confirm diamond size and value data for all lobes and pipes.

Micro-diamonds5 from drill core were used to create
local estimates of grade for the 5034 North-East Lobe and Tuzo Pipe.
Micro-diamonds are stones (less than 0.5 mm) recovered from the dissolution of
drill core using a caustic fusion process.
    These results were used for

_______________________________________
4 Macro-diamonds for the purposes of this report are
those stones recovered from LDD samples by a treatment process that involves
crushing and screening.

5Traditionally, stones retained on a 0.5 mm
square-mesh screen after sieving are referred to as macro-diamonds, while stones
that pass through the sieve are referred to as micro-diamonds. For the purposes
of this report, micro-diamond results refer to stones recovered from diamond
drill core subjected to acid digestion or caustic fusion. Strictly speaking,
these results may contain both micro- and macro-diamonds. The micro-diamond
treatment process involves dissolving the kimberlite in an acidic or caustic
solution and recovering any diamonds released above a specified bottom cut-off
(usually 75 μm or 106 μm). The micro-diamond results can be used to estimate the
grade in carats per hundred tonnes (cpht) of a kimberlite above a given cut-off.
Estimates of grade using micro-diamonds must be adjusted to reflect a realistic
bottom cut-off (e.g., 1.5 mm), and may need adjustment to reflect differences in
liberation and recovery in a commercial treatment plant and the micro-diamond
treatment process.

these cases primarily due to the difficulty of obtaining adequate macro-diamond samples for the purposes of local resource block estimation. In these cases, the available macro-diamonds were used for valuation purposes and for calibration of
micro-diamonds models.

|       | The 5034 pipe is composed of four joined kimberlite bodies, referred to as lobes and two small satellite pipes (North and South pipes; see Figure 7-4). In plan view the West, Centre and East Lobes have irregular, but
roughly circular shapes of approximately 80 m diameter. The North Lobe is comprised of a 35 m wide dyke-like protrusion, which extends from the East Lobe 300 m to the northnortheast. The North Lobe lies under a cap of 70 m to 80 m of granite,
which is likely to be in-situ. In this report, the North and East Lobes were treated as one lobe, the North-East Lobe, for the purposes of Mineral Resource estimation.

|       | The North-East and West Lobes exhibit a layered internal structure with kimberlite gradually changing texture from coherent hypabyssal kimberlite (HK) at depth to a fragmental tuffisitic kimberlite (TK) at shallower levels (see
also Section 7.3). In contrast to the layered structure of most lobes, the Centre Lobe is composed exclusively of HK, which cannot be subdivided using petrological or geochemical means. The hypabyssal kimberlite found in all four lobes is
geochemically and petrologically very similar, suggesting a close genetic relationship of all four lobes.

Hearne

The Hearne kimberlite consists of two
pipes, North and South, and comprises a mix of HK and TK (Section 7.3). The
North pipe is elongate with an approximate near-surface 55 m width and 215 m
length. The South pipe is roughly circular with a near-surface diameter of 90 m.
Each TK kimberlite can be distinguished geologically based on garnet content,
magma clasts, autolith-like bodies, xenoliths, and clay minerals. The names of
the different TK units are based primarily on their location within the two
pipes. The HK kimberlites represent the transition from diatreme to root zone
and are differentiated largely on the basis of garnet content and grade.

Tuzo

Tuzo pipe covers 1.27 ha at surface,
measures approximately 115 m x 110 m in plan, and is overlain by lake-bottom
sediments, glacial overburden, and the waters of Kennady Lake. The pipe is
circular at surface, but widens at depth, resulting in an unusual inverted
conical shape.

For the purposes of Mineral Resource
estimation, one of the fragmental units (TKTKT1) was subdivided into a
high-grade and a lower grade portion using macro grade information from LDD
samples taken in 1999 and 2008.

The High-Grade zone was originally
identified in 1998 from LDD data due to a zone of higher macro-diamond grade.
Subsequent logging and re-logging of existing core suggested overall slight
petrographic differences between the High-Grade zone and the adjacent
Low-Grade area, but also considerable textural inhomogeneities within the
High-Grade zone itself. A possible scenario to explain these features is that
the High-Grade zone is a feeder conduit that has collapsed and mixed on a
grain-by-grain basis with the surrounding tephra of the TK unit.

Although not an ideal approach, it is
relatively common industry practice to isolate a high-grade zone in this manner
where it is recognized that to not do so would cause undue spreading of the
anomalous (high into low, low into high or both) grade during an interpolation.
In this case, the approach is preferable, particularly where the data available
are insufficient in number to risk potential over-projection of high-grade
samples.

Grade Estimation - 5034 West and Centre
    Lobes

Estimation
Approach

For the West and Centre Lobes of 5034,
local block estimates were created within a 3D block model using the
macro-diamonds recovered from LDD. Grade was first estimated locally in carats
per cubic metre (cpm3) and then converted to cpht by applying a
global density for each lobe (grade in cpht is obtained by dividing grade in
cpm3 by density and multiplying by 100).

Large Diameter Drilling Data (Macro-diamond Data)

The 1999 LDD holes were drilled using a drill bit diameter of 12.25" over 18 m lifts: the 2001 and 2002 drilling used a 24" drill bit diameter over 6 or 12 m lifts. Table 17-1 summarizes the holes located in the West and Centre Lobes, and Table 17-2
summarizes the sample statistics by lobe.

A number of other issues were considered prior to the grade estimation of 5034 W and C Lobes:

The effect of different sample-support sizes of the two LDD programs. Different sample support sizes (in this case 311 mm and 610 mm diameter LDD drill holes) tend to result in similar grade means but different grade variances;
the larger support size has a smaller variance. A technique to adjust the sample variance of the smaller diameter holes was considered in 2003 but was not applied due to inconsistent results. In this report, as in 2003, no adjustment was made for
different hole diameters.The effect of different sample lifts, namely 6 m, 12 m, and 18 m. The issue of different sample lifts was resolved by regularization, a process that calculates the grade per mining bench height by combining or sub-dividing samples
into common lengths and weight averaging the diamond content over the new interval. For Gahcho Kué, a bench height of
12 m was planned, and grade values were drill-hole length weighted according to the drill-hole intersection per bench to accommodate sample lengths that varied from less than
12  m to greater than 18 m.The impact of clustering of the 2002 drill holes. To test the effect of the clustered LDD samples on the Mineral Resource estimates, a de-clustering method was tested but not applied for two reasons. Only small differences were
found between global grades using de-clustered data and clustered data, and the semi-variograms indicated that the correlation between sample points was preferentially orientated in a vertical rather than horizontal direction.Assess the diamond recovery differences between campaigns. Results from different campaigns exhibited differences in recovery characteristics, which were related to reasonably well-understood drilling conditions.

| |  | The impact on the Mineral Resource of the inclusion of
incidental diamonds6. While the CIM recommends that this fraction (<
0.85 mm) be excluded from Mineral Resource work, the total impact of including
these diamonds for the Mineral Resource estimate was demonstrated to be less
than 1% (calculated at a +1 mm bottom cut-off) which is considered to be within
the error of the estimation methodology and therefore not significant.
Consequently, the small amount of incidentals were used in the estimations.

_______________________________________
6Incidental diamonds are defined as stones recovered
below the reported bottom cut-off of the sampling or production plant. In a
producing mine, incidental stones are usually recovered during production. When
estimating a Mineral Resource, the estimator must decide whether to estimate the
grade, diamond size distribution and average diamond value inclusive or
exclusive of incidental diamonds. The decision must consider the fact that the
amount of incidentals is dependant on the design and operation of the Main
Treatment Plant (MTP) and the shape and size of the diamonds.

Composite
Preparation

The adjusted sample macro data were
imported into Gemcom® where they were bench composited to 12 m
lengths while honouring geology. The cut-off for the minimum length of
composites to be used in the estimation was investigated by comparing the
average cpm3 value of composites at several cut-offs
to ensure there was no bias in the selection of composite length. The difference
in the average cpm3 value between all composites, and those where
bottom cut-offs were applied, is negligible. To maximize the use of available
grade information, a minimum length of 6 m was imposed.

Histograms and Univariate
Statistics

Histograms and probability plots of the
12 m bench composites were generated for each rock type containing macro data.
Summary statistics are shown in Table 17-3.

Variography

Grade variography was conducted on the
12 m bench composites for each Lobe in 5034. Experimental correlograms were
calculated and modelled using Sage2001®. Directional correlograms
were generated using a 20 m lag: the vertical correlogram is based on a 12 m lag
spacing. Greatest continuity is in the down-dip direction for all rock units.
For the 5034 pipe this equates to the vertical orientation of the holes.

Local Grade
Estimation

A 25 m x 25 m x 12 m block model
project was defined in Gemcom®. Ordinary block kriging was performed
for each by a kriging estimator using two passes. Search ellipses were
orientated in the direction of continuity as defined by the correlograms. In
Pass 1 for 5034, the search radii were 75 m x 75 m x 50 m in the X, Y and Z
directions respectively. In Pass 2, search radii were increased to allow all
blocks within the model to be assigned a grade. Validation of the Mineral
Resource estimate included a visual inspection, comparison of statistics and
analyses to detect spatial bias and excessive smoothing. Table 17-4 shows the
percent difference between the kriged and nearest-neighbour (NN) block estimates
are typically less than five percent for any given rock type.

Density Model

AMEC performed a thorough review of all
available density data for the 5034 Lobes and Hearne Pipe. The 2003 Mineral
Resource estimate applied an in-situ (wet) density rather than a standard dry
density due to the limited number of dry density measurements available. In this
update, dry density was used where available. Where too few dry measurements
were taken, available in-situ density measurements were converted to a dry
density. The average dry densities by lobe were calculated for the Centre and
West Lobes and applied to the Mineral Resource model (Table 17-5).

|       | De Beers and other companies have used micro-diamond sampling to estimate diamond grade in kimberlites for some time. In almost all cases the approach was to estimate grade globally or per litho-facies. For the North-East Lobe the
estimation of global grade using micro-diamonds was extended to allow the estimation of local block grades. This was achieved by combining models of stone density and diamond size distribution data and by estimating stone density rather than carat
grade locally. Calibration and consistency of the models was achieved using macro-diamonds.

|       | This method was considered particularly apt for the North Lobe which lies below 60 m of granite that has proved difficult to penetrate using large diameter drilling (the conventional approach to kimberlite grade estimation). In
addition, the inclined nature of the North Lobe limited the amount of sampling that could be achieved from vertical holes. The use of micro- diamond sampling provided a practical method of estimating grade.

Table 17-6 is a summary of the core
drill holes treated for micro-diamonds used in this analysis, showing summary
depts with recovered stones and carats from 5034 East and North Lobes.

In order to eliminate irregular
recoveries in the very small size classes and to facilitate better comparison it
was decided to work with stone counts and stone density above the De Beers
micro-diamond size class md6, which represents diamonds larger than 0.00003 cts.
Diamond density was expressed in terms of stones per 10 kg.

A further breakdown of micro-diamond
sampling results by lobe and litho-facies is shown in Table 17-7. One drill hole
intersected the North pipe, and with the results for these samples similar to HK
from North and East lobes, it was decided to include its samples in the
analysis.

Diamond Size Distribution
Modelling

Individual size distributions for
micro-diamond samples were plotted and compared with other samples from the same
litho-facies to observe sample variability and to eliminate possible outliers.
No samples were identified as outliers. In addition, samples were plotted and
combined by hole and litho-facies to compare drill hole results.

Sample diamond-size distributions were
compared by Lobe and lithofacies (North and East Lobe data were kept separate)
and by lithofacies for the North and East Lobes together. The plots showed that
the smaller TKT sample totals from the East and North Lobes were more variable
and the North Lobe TKT indicated a coarser diamond size distribution than the
other litho-facies, while TKT from East lobe indicated exactly the opposite.
Combining the two sets of TKT samples resulted in a size distribution similar to
the other lithofacies.

This final comparison by litho-facies
between North Lobe and East Lobe suggests that the litho-facies all have a
similar diamond size distribution. The observation of a similar diamond size
distribution for all the litho-facies in North and East lobes supports the idea
of geological continuity from the East to the North lobe.

Macro-diamond results were subsequently
plotted for the different litho-facies to ascertain if the suggestion of a
similar overall diamond size distribution was also evident on the basis of
macro-diamond sampling results. In this comparison the North Lobe LDC sampling
results were plotted, along with the LDD results for East Lobe.

These plots exhibit a similarity of
macro-diamond size distributions and further confirm the observed geological
continuity between the East Lobe and the North Lobe.

Size distribution modelling was
concluded by obtaining the (log-normal) statistical parameters from the sample
diamond size distributions. Diamond size distribution modelling was done
iteratively by creating a diamond parcel based on the modelled diamond size
distribution, with an iteration comprising two million samples, which were
combined to form the diamond parcel.

The results were plotted on one graph
showing the micro- and macro-diamond sampling results. The process was repeated
until both micro- and macro-diamond sample results were satisfactorily
replicated.

In view of the common diamond size
distribution for all litho-facies it was concluded that differences in diamond
content between litho-facies and between North and East Lobes would be
attributed to differences in diamond density (stone density) and that the
spatial variability of diamond density would have to be established in order to
estimate diamond content in resource blocks.

Diamond Density Distribution (Stones per 10 kg) Modelling

Micro-diamond samples were analysed per litho-facies to obtain diamond density (concentration) models required for grade modelling.

In view of the similarity in stone counts between the TK and TKT lithofacies, it was decided to group these samples for modelling. This also increased the number of samples available for the procedure.  Furthermore, GKJV concluded that North Lobe
and East Lobe HK samples could be combined, as was the case for North Lobe and East Lobe HKT samples and for all the TK and TKT samples from North Lobe and East Lobe.

Estimation of Global Diamond Content per Lithofacies

Global diamond content was estimated by creating a diamond parcel for the litho-facies under consideration. This diamond parcel was based on the modelled diamond size and diamond density distributions (see above).

The diamond parcel was generated by simulating two million samples using the model attributes for diamond size and diamond density. A Monte Carlo simulation was then used to construct a diamond parcel as follows:

| |  | a sample stone density is drawn at random from the modelled stone density distribution                         
| |  | ---------------------------------------------------------------------------------------------------------------
| |  | the stones in this sample are assigned a weight by randomly drawing from the modelled diamond size distribution
| |  | the stones and weights from each draw are accumulated                                                          
| |  | the simulation is repeated until the required number of samples was drawn resulting in a diamond parcel.     

The parcel stones were allocated to size classes and presented in the form of log-probability and grade-size7 curves.  Diamond data for the corresponding micro- and macro-diamond sample parcels were plotted with the simulated parcel
curves for comparison.

Global estimates of grade were prepared for units HK, HKT and combined TK and TKT based on the simulated parcels.

_______________________________________7One way to view micro-diamond data (and estimate a grade) is to plot the micro-diamond results for a given kimberlite facies on a grade-size graph. In such a graph, the average size of the micro-diamonds in a particular sieve size is
plotted on the X-axis, and the grade of the sieve class in stones per tonne is plotted on the Y-axis. If the data are plotted using a log-log scale, a polynomial can be fitted to the data points and the grade of the kimberlite above a
bottom cut-off calculated by measuring the area under the fitted curve. The relative position of the fitted curve on the plot is indicative of kimberlite grade, while the curvature of the fitted line reflects the diamond size distribution.

The grade estimates prepared this way
represent the total diamond content. This means that the estimates include
stones that would not usually be recovered after treatment in a conventional
production treatment plant. Such grades are therefore optimistic relative to
what will be achieved in a conventional treatment plant and therefore require
adjustment. The global grades for the two lobes combined are shown in Table
17-8.

Spatial Estimation of Stone
Density and Proportioning of the Global Diamond Content

A spatial model for micro-diamond stone
density was created to obtain a spatial model and local estimates for
macro-diamond grade in carats/100 t. Local estimates for stone density were
calculated by means of kriging. This process involved a spatial analysis per
litho-facies to obtain spatial structure for stone density, followed by the
kriging process.

Variograms were modelled for units HK
and HKT combined for the two lobes and kriged using the combined micro-diamond
sample stone densities. A range of 60 m and a nugget effect of around 50% of the
sill were used with a kriging neighbourhood of 75 m in all directions for HK and
HKT, applying ordinary kriging in all cases. For the sparser sampled TKs, a
unique kriging neighbourhood was used.

By using calculated block tonnages and
kriged block stone density the corresponding block stones were calculated and
accumulated to total stones for each litho-facies. To obtain block carat
estimates at a given bottom cut-off, the corresponding total carat estimate for
the unit (zone) was apportioned into resource blocks in the ratio of block
stones to total stones for the unit.

Table 17-9 is a summary of global
grades at +5 ds derived from block carat estimates per litho-facies and lobe,
after localizing zonal diamond content.

Bulk Density
Model

Spatial analyses were performed using
dry density per unit for the combined lobes. Bulk densities for blocks were
estimated using a kriging estimator. Table 17-10 shows reasonable comparisons
between estimated blocks and sample data.

Grade Estimation - Hearne

Estimation
Approach

For the Hearne Pipe, local block
estimates were created within the 3D block model using the LDD results.
Estimates were constructed for 12 m benches across the entire pipe.

| | Large Diameter Drill Data
(macro-diamond data)
Similar to the drilling on 5034 West
and Centre Lobes, the 1999 LDD holes were drilled using a drill bit diameter of
12.25" over 18 m lifts: the 2001 and 2002 drilling used a 24" drill bit diameter
over 6 m or 12 m lifts. Table 17-11 summarizes the holes located in the Hearne
pipe. There are no macro-diamond data for rock units HNTKG2 AND HS_UNDEF.

Other Considerations Impacting
Grade Determination

Hearne macro-diamonds are impacted by
the same considerations presented for the LDD data from 5034 West and Centre
Lobes (see section 17.2.2).

Composite
Preparation

Hearne composites were prepared in the
same manner as the composites for 5034 West and Centre Lobes (see Section
17.2.2).

Histograms and Univariate
Statistics

Histograms and probability plots of the
12 m bench composites were generated for each rock type containing macro data.
Table 17-12 summarizes the statistics by rock type.

There are limited data available to
analyze the Hearne rock types. HNTKN and HNTKNT exhibit higher grades and
illustrate normal distributions: HNHKG contains low grade material with a
positively skewed distribution. Remaining Hearne units do not have sufficient
data to make an informed comment.

Units with limited data are difficult to model and are grouped
with units with similar statistical behaviour, specifically grade. Four rock
groups were created for Hearne Pipe based on geology, location and grade:

| |  | high-grade tuffisitic (TK_HG)  HNTKN (200), HNTKNT (201), HNTKSD (205)
| |  | -----------------------------------------------------------------------

Variography

Grade variography was conducted on the 12 m bench composites
for each rock group as defined above. For the Hearne units, maximum continuity
is down dip following the interpreted dip direction of the rock units. Defined
correlogram models were imposed on rock units demonstrating limited structure
due to insufficient data. Experimental correlograms with limited data were
modelled with structures of a group with similar grade. The correlogram model
for Hearne TK_HG group was imposed on the Hearne HK_MG group with a slight
modification to the range in the Z direction. The model for Hearne HK_LG group
was imposed on the Hearne TK_MG group.

Local Grade Estimation

A 25 m x 25 m x 12 m block model project was defined in
Gemcom®. Ordinary block kriging was performed for each lobe, and the
kriged estimates were validated globally and locally by a NN model generated for
each lobe.

Ordinary block kriging was performed for each rock type with
the exception of HS_UNDEF. The kriged estimates were validated by a
nearest-neighbour (NN) model generated for each rock type. Soft boundaries
between rock types within the same rock group were imposed.

Solid models exist for two Hearne rock
units which have no macro data; HNTKG2 and HS_UNDEF. HNTKG2 sits just below the
overburden surface in the south of Hearne North. As a result of its position in
relation to Hearne South and its commonality in rock units (tuffisitic), HNTKG2
is estimated using HSTKM and HSTKW data and TK_MG estimation parameters.

Kriging was performed using two passes.
The Hearne search strategy follows the strategy of mining bench-by-bench due to
the slender north-south striking nature of the body. Search radii reaching the
north-south and east-west extents aimed to include all allowable composites
within a limited number of surrounding benches. Search radii are dependent on
rock type for both passes. In the second kriging pass, search radii were
increased to allow all blocks within the model to be assigned a grade.

Validation of the Mineral Resource
estimate included a visual inspection, comparison of statistics and analyses to
detect spatial bias and excessive smoothing. Table 17-13 and Table 17-14 show
the percent difference between the kriged and NN block estimates for rock type
and rock group.

Table 17-13 shows the percentage
difference between the kriged and NN block estimates are typically less than
five percent for any given rock type. Rock types with percent differences around
10% are those belonging to the HK_MG group (HNHKN AND HNHKG2). The difference in
the composite means of these rock types is close to 1.000 cpm3; hence
estimating using soft boundaries is the main reason for the percentage
differences observed. Table 17-14 shows the comparison of statistics for the
kriged and NN models by rock group. Percentage differences between the kriged
and NN means are generally less than 4%, illustrating no bias exists in the
estimate.

Initial estimation was completed
without the capping of potential outliers. Validation results showed this not to
be a problem for all units with the exception of HNHKG. Kriging estimation of
HNHKG was overestimating the composite mean by 10%. The locations of three
higher grade outliers were identified on the units boundary with rock units
with higher grades, and composites were capped to 3.0 cpm3. Both
kriged and NN estimation were re-run with improved results.

Bulk Density
Model

AMEC performed a thorough review of all
available density data for the 5034 Lobes and Hearne Pipe. The 2003 Mineral
Resource estimate applied an in-situ (wet) density rather than a standard dry
density due to the limited number of dry density measurements available. In this
update, dry density was used where available. Where too few dry measurements had
been taken, available in-situ density measurements were converted to a dry
density.

The average dry densities by lobe were
calculated and applied to the Mineral Resource model using the values in Table
17-5.

|17.2.5 | Grade Estimation  Tuzo
|------ | -----------------------
|       |                        

Estimation
Approach

As with 5034 North-East Lobe, the
estimation of global grade using micro-diamonds was extended to allow the
estimation of local block grades. This was achieved by combining models of stone
density and diamond size distribution data and by estimating stone density
locally. Calibration and consistency of the models was achieved using
macro-diamond data collected from large diameter percussion drilling in 1999.

The close-spaced drill grid (35 m) in
2007 had the advantage of providing a high quality geological data set that
included quantitative measures of dilution throughout the Tuzo body.

Estimation was carried out in three
stages; estimation of global diamond content per litho-facies, estimation of
block tonnage and finally local estimation of grade per mining block. A more
detailed discussion on the estimation approach can be found in Section 17.2.3.

A key difference at Tuzo is the need
for a dilution model on a local basis. Dilution was estimated in blocks so that
a more accurate tonnage calculation can be made in the model. Consequently,
grade estimates must be fully diluted. This is achieved through the use of the
2007 micro-diamond dataset.

Estimation of Global Diamond
Content per Litho-Facies

Diamond size was the first component of
diamond content to be modelled. Samples were combined and plotted on
log-probability plots to observe the size distribution per litho-facies and to
express the distribution of diamond size per litho-facies in terms of a
statistical distribution. Diamond stone density or diamond concentration was the
second component of diamond content to be modelled. Stone density was used to
estimate diamond concentration by zone per litho-facies and locally in resource
blocks. The statistical distribution of stone density was modelled per
litho-facies and expressed in terms of a statistical distribution. The
combination of stone density distribution and stone size distribution was used
to reproduce (simulate) a representative diamond parcel statistically for
comparison with observed samples.

Estimation of Block
Tonnage

A detailed set of dilution measurements
of drill core was prepared for every hole. The dilution measurements were used
in a spatial analysis to obtain an estimate of the percent dilution in each
resource block. Estimates for undiluted kimberlite density and granite density
were combined with the percentage block dilution to calculate a block tonnage.
Density estimates for kimberlite and granite were estimated locally. Block
volume was split into kimberlite and granite volume on the basis of the block
dilution estimate and converted into tonnages by means of the kimberlite and
granite density estimates. The two tonnage components were combined into a
single block tonnage and used with block volume to derive an overall block
density estimate.

Local Estimation of Grade

An estimate of stone density was made per mining block.  These local estimates and block tonnages were used to calculate block stones, which were accumulated to total stones per litho-facies. The individual estimates of stones per mining block and
the total stones per litho-facies were used with the global carats per litho-facies to calculate the carats in each mining block. The mining block carats were divided by the block tonnes (the total of kimberlite and granite tonnes) to give a grade
in carats per 100 tonnes (dry).

The estimation procedure involved the following steps (described in more detail below):

Sampling Data

A total of 367 samples of core were treated for micro-diamonds. The average sample weight was 8 kg comprising 2 m drill core sections and amounted to a total sample weight of 2,860 kg. The average dilution for the micro-diamond samples is 37%.

Table 17-15 shows a summary of micro-diamond recoveries broken down into the nine litho-facies units identified for the body.

Small numbers of samples were collected from units TK and EU with low likelihood of being used in advanced spatial analysis for diamond content.

Results from the 1999 and 2008 LDD programmes were incorporated into this study and used in combination with micro-diamonds to model diamond size distributions to ensure that the diamond size distribution is coherent over the entire diamond size
range.

Table 17-16 shows a summary of LDD
results broken down per litho-facies. No macro-diamond results were available
for unit HK. Diamond recovery took place at a bottom cut-off of 1.5 mm; all
stones are reported including those recovered below the bottom cut-off. Samples
were not weighed, but sample volume was derived from hole-diameter and used in
combination with density estimates to calculate an equivalent sample weight, as
shown.

Diamond Distribution
Modelling

A cumulative size distribution curve
was plotted for each micro-diamond sample to check for outliers with high sample
counts. None were found. Initially individual size distribution models were
fitted using micro- and macro-diamonds to model a distinct size distribution for
each litho-facies. Modelling was done by means of probability plots of
micro-diamond and macro-diamond results for each unit. In some cases the
grade-size curve was used to assist in determining an acceptable size
distribution model. After reviewing the resulting plots, it was decided that a
single distribution could reasonably be fitted to all rock types.

Initial parameters were established by
means of a graphical method, followed by an iterative process in which a
representative diamond parcel was simulated and plotted with the samples. This
procedure was performed with great care not to allow adverse influence of
sparsely populated size classes at the top end of the diamond size range. As a
check for consistency, recovery factors were added to the simulated parcel, and
the resulting truncated distribution was compared with the macro-diamond
results. As an additional check, the simulated parcel was plotted with
micro-diamond and macro-diamond results on a grade-size plot. These comparisons
were reasonable.

Diamond Density Distribution
Modelling

Sampled stone densities were modeled to
obtain a statistical distribution of stone density for each litho-facies unit.
Stone density statistics derived from micro-diamonds are shown in Table 17-17.
Table 17-17 shows that stone density (+md5) for unit HK is highest at 34
stones/8 kg, followed by TKT2 at 23, TKTKT1H at 23, TK at 16, TKTKT1L at 14 and
TK TKT2 at 11.

Histograms of stone density (diamond
concentration in stones/kg) were used to create stone density models for each
litho-facies where sufficient sampling was available. Due to the small number of
samples, no models were created for units EU and TK.

Estimation of Global Diamond
Content per Litho-Facies

The stone density models and diamond
size distribution models were used to generate a diamond parcel for each
litho-facies. A typical diamond parcel was generated for each litho-facies by
simulating two million samples, with stone density and stone size appropriately
drawn from the fitted.

Spatial Estimation of Stone
Density and Proportioning of the Global Diamond Content

Local diamond content was estimated on
the basis of the spatial distribution of stone density, using kriging.

Kriged estimates for stone density were
used to split diamond content into resource blocks to form local diamond content
estimates.

Stone density was analysed to determine
spatial structure for diluted stone density. The local estimation procedure
comprised kriging of stone densities, which were expressed as stones per 8 kg of
sample, and used in a geostatistical analysis to examine its spatial structure
in the body.

Validation of the kriged estimates was
acceptable on a global basis, with no overall bias introduced.

The kriged block estimates were used to
localize diamond content per litho-facies into resource blocks in terms of
carats/100 t for recovery of stones greater than 1.5 mm (+5 ds).

The estimated zonal carat total was
proportioned into the resource blocks in the zone on the basis of individual
block stones (+md5). The proportion of block stones (+md5) to the total stones (+md5) for the litho-facies was
applied to the total carats for the litho-facies to derive block carats at a
nominal 1.5 mm or 1.0 mm bottom cut-off expressed as grade in carats/100 t.

estimates and +5ds LDD sampling results. There are two comparison estimates
using macro-diamonds. One is the overall average (middle columns) and the other
is the declustered estimate from macro-diamonds (NN) in the right hand columns.
All results show reasonable comparison between estimated grade and LDD sampling
grades for all the units, except in the case of unit HK, where no macro-diamond
grade was available.

Dilution Estimates at
Tuzo

Granite dilution is significant at
Tuzo. To understand the distribution of granite locally, a 3D model of crustal
(granite) dilution was made using the 2007 core drilling (27 holes on a 35 m
grid) and the most recent geological model update. Ordinary kriging was employed
for estimation.

The major geological units were
retained for analysis and estimation. Where insufficient numbers of samples were
available to conduct confident statistical analysis, a zonal average was
assigned. All fragmental kimberlite units were also combined as one and compared
to the various individual units to determine the individual effect that each
unit has on the estimates. The analysis focused on the upper part of the Mineral
Resource, i.e., 408.92 to 60.92 masl. The granite raft at depth was excluded
from the dilution data set. Ordinary kriged estimates validated well against
sample data. An example validation plot is shown in Figure 17-1.

Bulk Density
Model

Equal lengths of core were selected to
determine density. A total of 679 samples were selected, and samples were logged
as either kimberlite or granite. Measurement of kimberlite and granite density,
combined with a block estimate of percentage dilution, enabled calculation of
the kimberlite and granite tonnage in each resource block.

Table 17-19 summarizes average density
resulting from the kriging process in the litho-facies units as defined in the
block model and gives comparisons with sample data.

Comment

Review of this approach showed that the
samples used to estimate kimberlite density contained variable amounts of
granite. The impact is an overestimation of kimberlite tonnes in a block and
carats in a given litho-facies; grade is not impacted. Investigation suggests
that final block densities are between 1% and 5% higher (depending on
litho-facies) when compared to an average of sample density. Further, if the
average of the lowest kimberlite densities in a litho-facies is substituted for
the average kimberlite density used, the likely real kimberlite density is
between 0% and 4% (lower) than that used.

Modifying Factors for Grade and Diamond Size
      Distributions

Introduction

Modifying factors are typically applied
to Mineral Resource grades to estimate the recovered grade of a Main Treatment
Plant (MTP). For conventional bulk sampling using macro-diamonds, these factors
accommodate differences in liberation and lock-up between the product obtained
from drilling (i.e. drill chips), and the final diamond recovery at the MTP.

Where the design of the MTP is known
(say during a feasibility study), process models may be used to indicate the
degree of crushing and recovery efficiency of free diamonds that can be obtained
for a given plant design. These process models can be used to estimate the
factors used to adjust the diamond size distribution, average diamond value and
resource grade. Where the final design of the MTP is unknown, then an assumption
may be made that the MTP will crush and recover diamonds from the kimberlite at
least as well as the LDD and bulk sample treatment processes.

Mineral resource grades based on
micro-diamonds typically estimate a total content grade and diamond size
distribution at a defined bottom cut-off. This grade and size distribution are
only valid if a similar process to that used to liberate and recover the
micro-diamonds is followed in the MTP i.e. the kimberlite is dissolved and all
stones recovered. Although such a process would maximize diamond recovery, a
conventional MTP typically employs crushing, screening, dense medium separation
and X-ray recovery and is not designed to release or recover all the stones in
the kimberlite but rather the majority of the intrinsic diamond value.

This means that the smaller (lower
value) stones may not be fully released or recovered. To avoid presenting a
misleading grade, the total content grade and size distribution is typically
adjusted to allow for conventional production.

Herein the diamond size distributions
were modelled to extraction and recovery processes of the bulk sampling and may
differ from the characteristics of a specific MTP. As such further adjustments
to the grade and average dollar per carat may be required when a final treatment
process is finalised.

Modifying Factors for 5034 West
Lobe, 5034 Centre Lobe, and Hearne Pipe

The grade of the 5034 West Lobe, 5034
Centre Lobe, and Hearne Pipe were estimated using macro-diamond data from bulk
samples collected at a bottom cut-off of 1.5 mm. Analyses completed on the LDD
results concluded that no adjustments were recommended to the grade estimates
based on the LDD results from 5034 West Lobe, 5034 Centre Lobe and Hearne Pipe.

The corresponding diamond size
distributions were estimated using micro-macro grade-size models where factors
were applied to the total content diamond size distributions to reflect
conventional MTP recovery (including incidentals) at a bottom cut-off of 1.5 mm.

Factors were also applied to bring the
total diamond size distribution to a grade of 1.0 mm. As no sampling was carried
out at this bottom cut-off, the difference in diamond content between the 1.5 mm
bottom cut-off and the 1.0 mm bottom cut-off was expressed as a ratio. This
ratio was then applied to the 1.5 mm grade estimates to arrive at a 1.0 mm grade
for each Mineral Resource estimate.

The resulting diamond size
distributions at the 1.0mm bottom cut-off (including any incidental diamonds)
are shown in Table 17-20.

Modifying Factors for the 5034
North-East Lobe

For the 5034 North-East Lobe a total
content grade and diamond size distribution was estimated at a bottom cut-off of
1.0 mm (2 ds). These estimates assume that the recovery process will recover all
the stones above the 2 ds. In reality, a conventional MTP employing crushing,
screening, dense medium separation and X-ray recovery is not designed to release
or recover all the stones in the kimberlite processed.

For this reason, factors were applied
to the total content grade and size distribution to allow for recovery in a
conventional treatment plant.

A single diamond size distribution was
estimated for the North-East Lobe. Table 17-21 shows the resulting diamond size
distribution.

The 1.5 mm factors were calculated by
comparing the 1999 and 2001 LDD results from the East Lobe with the estimated
total content size distribution for the combined North and East lobes. The two
stone size distributions were compared on a grade-size plot where the LDD
results were adjusted to match the total content size distribution. The ratio of
the LDD stone grade to the total content stone grade was calculated for 5 ds and
below. The ratio was set at 1.00 for 6 ds and above with the assumption that all
stones greater than 5 ds would be released and recovered. A similar process was
followed for the 1.0 mm factors, except the total content stone distribution was
compared to the 2007 LDD RC drill results. The core from this drilling was
crushed and treated through a bulk sample plant with a nominal bottom cut-off of
1.0 mm.

|       | For Tuzo Pipe a total content grade and diamond size distribution was estimated at a bottom cut-off of 1.0 mm (2 ds). These estimates assume that the recovery process will recover all the stones above the 2 ds. In reality, a
conventional treatment plant employing crushing, screening, dense medium separation and X-ray recovery is not designed to release or recover all the stones in the kimberlite processed. For this reason, factors were applied to the total content grade
and size distribution to allow for recovery in a conventional treatment plant.

|       | One size distribution was estimated for all of the units in Tuzo Pipe. The resulting diamond size distribution at the 1.0 mm bottom cut-off (including any incidental diamonds) is shown in Table 17-22. The 1.5 mm factors in were
calculated by comparing the 1999 and 2008 LDD results from Tuzo Pipe with the estimated total content size distributions for each rock unit. In each comparison the two stone size distributions were compared on a grade-size plot where the LDD results
were adjusted to match the total content size distribution. There were no bulk sample data for Tuzo at a bottom cut-off of 1.0 mm. For this reason, the 1.0 mm adjustment factors estimated for the North-East Lobe were used at Tuzo to create an
adjusted grade and size distribution at a bottom cut-off of 1.0 mm.

|       | This section is broken down into three sub-sections. Section 17.3.2 deals with the basic classification of the Mineral Resource models and the criteria that were used. Section 17.3.3 summarizes the assumptions and use of open-pit
shells (here completed with Whittle®software) to assess the reasonable prospects for economic extraction of the estimated Mineral Resource. Diamond pricing estimates are necessary to value the resource blocks in the
Whittle®runs, and these are also discussed.

|       | In classifying the Mineral Resource, qualitative levels of confidence in the geological model and the estimates made up of volume, grade, density, and average diamond value were assessed. The assessment also considered data
integrity, methodology and adherence to procedures.

|       | The risk for 5034 is the small size and irregular root zone nature of the body that may impact volume estimates and edge dilution. For the 5034 West and Centre Lobes, a lobe model was assumed in which
internal geological units were not estimated separately: this may result in more variable grades than anticipated from the current model. For the North-East Lobe the geological models and resulting volumes are based on an internal geological
model.

| | Simulation studies performed using LDD
sampling show that the number of samples and their location in the West and
Centre lobes is sufficient to define an Indicated Mineral Resource above 121
masl. No simulation studies were carried out for grade estimates in the
North-East Lobe, but the amount of sampling given the shape and size of the
North-East body is considered adequate for an Indicated Mineral Resource above
121 masl. The diamond parcel available for revenue estimation from 5034 is in
excess of 3,000 ct and is adequate for average price calculations.

The North Pipe of 5034 is defined as an
Inferred Mineral Resource. Limited sampling has resulted in a poorly defined
volume and geological model. Micro-diamond data were used to estimate a zonal
grade (overall average grade assigned to all blocks) for the pipe, and the
diamond size frequency distribution for revenue purposes. No macro-diamond data
are available for assortment analysis. For the purposes of estimating an average
diamond value, the North Pipe was assigned the assortment data used for the
North-East Lobe on the basis that the rocks in North Pipe are proximal to the
North-East Lobe and are texturally and geochemically similar.

The South Pipe of 5034 is defined as an
Inferred Mineral Resource. As with the North Pipe, there is limited sampling for
this pipe resulting in a defined volume and geological model of lower
confidence. Micro-diamond data were used to estimate a zonal grade for the pipe
and a diamond size-frequency distribution. No macro-diamond data are available
for assortment analysis. For the purposes of estimating an average diamond
value, the South Pipe was assigned the assortment data used for the West Lobe.
This is based on the proximity of the West Lobe to South Pipe. The South Pipe
lies on the same structural trend as the West Lobe and is joined to West Lobe by
a thin ribbon of brecciated kimberlite. Unlike the North Pipe, no whole rock
chemistry was carried out to confirm geological similarity between the South
Pipe and West Lobe. The West Lobe assortment is the lowest value assortment of
5034.

The volumes of the North and South Pipe
are relatively small when compared to the rest of 5034 (2.5 and 3.6 %
respectively of the 5034 volume and 0.9 and 1.3 % of the total Gahcho Kué
volume).

The risk in the Hearne Pipe is the
internal geological model which is complex. Simulation studies have shown that
sample data for grade are sufficient to define an Indicated Mineral Resource
above 217 masl. The number of samples falls off rapidly with depth. The
macro-diamond parcel is in excess of 2,700 ct, and is sufficient for both size
frequency distribution and assortment analysis.

Tuzo pipe is geologically complex and
carries significant amounts of dilution that is irregularly distributed
throughout the body. Based on the 2007 core drilling program and the LDD carried
out in 2008, an Indicated classification was applied for all parts of the
Mineral Resource above 121 masl.

Six of the 2007 Tuzo holes were drilled
to 400 m depth or approximately 100 m below the base of the current Indicated
Mineral Resource. All six holes remain in kimberlite, and the pipe remains open
at depth. Using these data the kimberlite was modelled for a further 50 m below
the Indicated level of 121 masl, and grades were estimated for mining blocks in
this zone in a similar way to the estimation of the Indicated Mineral Resource.
This 50 m section of the Tuzo model was classified as an Inferred Mineral
Resource. There is limited macro-diamond sampling (14.5 carats above 5 ds) below
121 masl, and therefore the assortment information from the uppermost 300 m was
used to estimate an average diamond value. This is considered reasonable for the
TKTKT2 unit which was macro-sampled above 121 masl.

The TKTKT2 unit comprises circa 56% of
the volume within the Inferred Mineral Resource at Tuzo. The remaining part is
made up of mostly HK (circa 43%) that has limited macro-diamond sampling (14.5
carats). The HK was shown to be texturally and geochemically different from the
fragmental (the TK rocks) above. There is a risk that the HK rocks will have a
different diamond assortment to the one assumed (lower or higher), with the
result that the average diamond value will differ from that estimated. It should
be noted that the Tuzo assortment has the lowest value assortment of Gahcho Kué
and is lower than the 5034 North-East Lobe assortment comprising mostly HK
rocks.

|       | Diamonds occur in very low concentrations, measured in
      parts per million for smaller-sized stones and parts per billion for
      larger stones (greater than 1 ct). Kimberlite samples vary in size
      depending on whether the intention is to assess the average grade, the
      diamond size distribution, or the average value of the pipe. The majority
      of diamond value is derived from the larger stones in the diamond size
      distribution. Even for large parcels of diamonds (10,000 ct or more) it is
      often difficult to obtain enough stones in the larger sieve classes to
      confidently estimate an average diamond value for that size class. As a
      result, it is usual in the diamond industry to model the diamond size
      distribution and/or the diamond value distribution8to reduce
      the effects of sample size on the estimation process. In estimating the
      average diamond value for each kimberlite source, both diamond size and
      diamond value were modelled.

8Assessing the average diamond value per carat for a
kimberlite requires knowledge of the diamond size distribution and the diamond
value distribution. The diamond size distribution is a measure of the carat
weight per size class. The diamond value distribution is the average value per
carat in each sieve class and requires knowledge of the diamond assortment. The
assortment distribution is more complex, requiring the carats in a given sieve
size to be sorted and valued according to price. Diamond value is a combination
of four parameters: size (ds), model (shape of stone), colour, and quality.

Diamond damage is not specifically
addressed in the calculation of dollars per carat. However, the larger part of
the parcels values is derived from the 2000, 2001, and 2008 LDD sampling in
which diamond damage was much reduced relative to the 1999 campaign.

5034 Lobes, North Pipe, and South
Pipe

Approximately 3,000 cts were valued
from the Centre, West, and East lobes over three drilling campaigns in 1999,
2000, and 2001. A further 115 cts were recovered from LDC drilling carried out
in 2007 at the northern end of the North-East Lobe. These data were not used for
valuation purposes but were used to help validate the diamond size distribution
estimated for the North-East Lobe. The two LDD programs of 2001 and 2002
constitute the majority of the diamond parcel available for revenue
analysis.

For the West and Centre lobes, the
combined micro-diamond and macro-diamond data were used to generate a diamond
size distribution per source. This approach was used to accommodate different
bottom cut-offs and different degrees of liberation in the macro-diamond bulk
sampling. The same micro-macro models were used to estimate a single factor per
source to move the 1.5 mm grade estimates to a 1 mm bottom cut-off (no bulk
sampling was performed at the 1.0 mm bottom cut-off).

Grade estimates for the West and Centre
lobes were made using bulk samples extracted from LDD. For the North-East Lobe a
total content grade and diamond size distribution was estimated using
micro-diamond samples at a bottom cut-off of 1.0 mm (2 ds). These estimates
assume that the recovery process will recover all the stones above the 2 ds. In
reality, a conventional MTP employing crushing, screening, dense medium
separation and X-ray recovery is not designed to release or recover all the
stones in the kimberlite processed. For this reason, adjustment factors were
applied to the total content grade and size distribution to allow for recovery
in a conventional treatment plant (see Section 17.2.6).

Comparison of the average diamond value
per sieve class for the West, Centre, and East lobes showed that the Centre and
East lobes had similar average diamond values per sieve class, while the West
Lobe showed slightly lower average values in the -13 +6 sieve sizes. For this
reason, two revenue distributions were prepared, one for the Centre and East
lobes, and one for the West Lobe.

For the Centre and East Lobe diamond
value model, the average diamond value per sieve class was adjusted for diamond
sieve9 classes +6, +15, +17, +19, +21, and +23. The same size classes
were adjusted in the West model. In making the adjustments a composite revenue
model was used as a guide. This model is based on data from kimberlite mines in
the De Beers Group that have similar dollar per carat per sieve class
values.

There are no macro bulk samples from
the North Lobe, the North Pipe, and the South Pipe. For the North Lobe and North
Pipe the value model is assumed to be similar to the Centre and East lobes. For
South Pipe value is assumed to be similar to West Lobe. Considerable geological
modelling was carried out for the East and North lobes that has demonstrated
connectivity and continuity of geology between these two lobes. For this reason,
the assumption of a similar assortment in the North Lobe to diamonds in the East
Lobe is considered reasonable. Limited work was carried out on the North and
South Pipes. The North Pipe lies 150 m north of the North Lobe. Whole-rock
chemistry analysis of samples from the North Pipe suggests similar rocks to
those in the North Lobe. For this reason assuming a similar value model to the
North-East Lobe is considered reasonable. The South Pipe lies approximately 200
m southwest of the West Lobe and lies on the same structural trend as the West
Lobe. The South Pipe is joined to the West Lobe by a thin ribbon of kimberlite.
No whole-rock chemistry was carried out to confirm geological similarity between
the South Pipe and the West Lobe. Although the geological association with West
Lobe is less certain than for North Pipe and North-East Lobe, the assignment of
the West Lobe value model is considered reasonable for an Inferred Mineral
Resource. The West Lobe model is the lowest value model of the 5034 Lobes.

Hearne Pipe

Grade estimates were made using macro
diamond samples extracted using LDD. A total of just over 2,900 cts was
recovered between 1998 and 2002 from the Hearne pipe. Analysis of the diamond
size distributions concluded that a single size distribution is adequate to
represent all the geological units present in Hearne. This is supported by the
grade-size plots generated from the micro- and macro-diamond data. The grade-size plots for the different units all tend to have the same
profile, indicating a similar diamond size frequency distribution.

_______________________________________
9LDD diamonds recovered during drilling campaigns
are discussed in terms of diamond sieve (ds) sizes. The sieve numbers are 23,
21, 19, 17, 15, 13, 12, 11, 9, 7, 5, 3, 2, and 1. Each sieve represents a
punched metal plate with round holes of a set diameter. The lowest number
represents the smallest opening and the largest number the widest opening. The
diameter of the holes for diamond sieve 1 is approximately 1 mm and the diameter
of the holes for diamond sieve 23 is approximately 10.3 mm. De Beers typically
uses these sieves for sizing the production from its mines and for revenue
analysis.

After examination of the diamond value
data by rock type and by year, it was concluded that there was no reason to
generate separate diamond revenue models per rock type. In modelling the value
distribution for Hearne, the average diamond value per sieve class was adjusted
for diamond sieve classes +5, +15, +17, +19, +21, and +23. As with pipe 5034,
the adjustments were made using a composite revenue model as a guide.

Tuzo Pipe

For Tuzo Pipe a total content grade
and diamond size distribution was estimated using micro-diamond samples at a
bottom cut-off of 1.0 mm (2 ds). These estimates assume that the recovery
process will recover all the stones above the 2 ds. In reality, a conventional
MTP plant employing crushing, screening, dense medium separation and X-ray
recovery is not designed to release or recover all the stones in the kimberlite
processed. For this reason, adjustment factors were applied to the total content
grade and size distribution to allow for recovery in a conventional treatment
plant.

For the Tuzo pipe, approximately 600
cts were recovered in the 1998 and 1999 LDD campaigns, and a further 1,600 cts
were recovered in 2008. The 2008 stones were recovered from two clusters of
holes drilled in the near-surface high-grade portion of the pipe. These bulk
samples were used to determine an average diamond value but were not used
directly to determine grade.

The bulk of the carats for value
modelling are taken from the high-grade zone of the pipe. Previous work based on
the 1998 and 1999 parcel of 600 cts indicated that the assortment was not
expected to differ within the fragmental rocks (these dominate the top 300 m of
kimberlite). One hole was drilled to 300 m depth away from the clustered holes
as a check on this assumption. Analysis of assortment data from this hole did
not indicate any change in assortment.

A single assortment profile was
modelled for the Tuzo diamond population. An adjustment was made to the average
diamond value per sieve class for diamond sieve classes +15, +17, +19, +21, and
+23. As with pipe 5034, the adjustments were made using a composite revenue
model as a guide.

Average Price (AP) Modelling 
WWW International Diamond Consultants

AMEC has assessed a comparative
valuation of the projects diamonds. The basis for the analyses was provided in
a 2008 confidential report authored by WWW for MPV. The report was then provided
to AMEC. Average pricing from this assessment could not be used directly from
the study because of its use of older (circa 2007) size distributions, older
interpretations of geologic units and certain assumptions in the methodology.
AMEC developed comparative estimates of average pricing using the WWW model work
coupled with the latest size

distributions and geologic models
generated in constructing the 2009 Resource Model. These results are shown in
Table 17-24 (column b). AMEC is of the opinion that the work, while yielding
some differences as compared to the De Beers valuations, is comparable overall,
and that it should be considered on an equal basis when developing suitable
average diamond pricing to assess reasonable prospects for economic
extraction.

In a report addressed to MPV dated 14
November 2008, WWW International Diamond Consultants Ltd. expressed the
following opinion, which they have consented may be quoted herein:

[WWWs price] models are based on
the diamond market as at 13th October 2008. Since then
diamond prices have fallen significantly and there is much uncertainty in the
market WWW is considering further reductions to its price book dependent upon
the results of upcoming tenders, and market sentiment. In the short term these
adjustments are likely to be more than 25 percent.

The problem at the moment is that
as the general liquidity crisis has spilled over into diamonds we are at a point
where for large swathes of rough diamonds there is effectively no market. In the
context of putting a value on a production which will take several years to
realise. WWW believes that it being sensibly conservative to use this October
price book. To base prices on the fluctuations over the past few weeks of
unprecedented economic turmoil in the world markets would be as meaningless as
not recognising any decline in prices at all.

However, even with the current
difficulties, WWW has not amended its longer-term view that the anticipated
shortage of supply will result in rising rough prices. Although the current
correction in prices was anticipated, the unexpected vehemence of general market
conditions means that the correction may be steeper and longer. Assuming a
return to some normality, WWWs view remains positive on long term prices, and
with the current general financial difficulties likely to defer or reduce future
production actually provides some additional support for this view. Inevitably
the time when the supply shortage will kick in will be pushed back as demand
takes time to recover but in the context of the time to put a mine into
production the basic economic scenarios still appear sound.

Use of Pit Shells to Delineate
the Mineral Resource

De Beers used Whittle®
software to establish open-pit shells within which the Mineral Resources were
declared. The De Beers work was checked by AMEC, and the software was found to
have been correctly used. The Whittle® runs use a set of reasonable
parameters to control their generation. The shells do not incorporate detailed
engineering design but use parameters that provide reasonable latitude for
necessary refinements. Table 17-25 shows input parameters used to generate the
pits.

The Whittle software varies the prices
according to a factor (revenue factor) and generates a breakeven pit for each
revenue factor. These pits should be considered conceptual. They incorporate
allowances for access roads (ramps). A detailed manual design will be required
to convert Mineral Resources to Mineral Reserves as part of pre-feasibility or
feasibility studies.

Figure 17-2 illustrates the response in
the contained Mineral Resource (shown here by carats) to the change in revenue
factor applied. Figure 17-3 shows the response in the resource tonnage against
the change in the revenue factor. 5034 and Hearne are relatively insensitive,
but Tuzo is quite sensitive at depth. Figure 17-4 shows a perspective view of
the selected pit used to declare Mineral Resources. This pit has a revenue
factor of 1.26 (applied to De Beers prices, column c in Table 17-24), and is
approximately equivalent to the pit that would be obtained if the prices shown
in column e of Table 17-24 were used).

Mining in kimberlites is not usually
selective because there is typically no secondary evaluation of block grade (no
blast hole sampling). On some operations there can be selectivity at the scale
of a geological unit (a basalt breccia for instance or a low-grade zone of
kimberlite). There are no such situations anticipated in 5034 or Hearne, but it
is likely that the large granite raft in Tuzo could be separated as waste.

Assessment of Reasonable
Prospects of Economic Extraction for Underground Mining

AMEC has assessed the prospects for
economic extraction of the remaining diamond-mineralized material that exists
below the pit shells discussed in the previous sub-section assuming underground
mining methods. The majority of the material occurs in the Hearne pipe and can
be seen in the perspective view in Figure 17-4.

Hearne to Tuzo is about 2 km)



Table 17-26 documents the cost and
revenue assumptions used in the analysis. The revenue portion is calculated
specifically for the material lying outside the resource pit shell discussed in
the previous sub-section. The underground mining costs are estimated from
existing operations in the NWT where sub-level open benching mining methods have
proven feasible. At a net revenue available to cover mining of C$102/t, the
estimated mining costs are met, with some additional margin to cover
development, thus supporting declaration of Mineral Resources.

Discussion

Should there be a decision to proceed
with development of the Gahcho Kue Project, completion of a feasibility study
and acquisition of the necessary permits would occur several years from present.
On this basis, and considering the opinion expressed by WWW, AMEC has taken a
long-term view of the prices that might be expected to support the reasonable
prospects for economic extraction that is necessary for the declaration of
Mineral Resources.

For the purposes of Mineral Resource
declaration and best current assessment of reasonable prospects for economic
extraction, AMEC has selected Mineral Resources within the Whittle®shells defined by a revenue factor greater than 1.0. The revenue factor
used (1.26) is approximately equivalent to taking the average of the price
comparisons (Table 17-24, column d) and adding 20% to reflect long-term
assumptions (column e). These pricing levels occur close to the WWW High
sensitivity cases. The price levels are also similar in nature to long-term
prices that could be derived under forward price escalation models that are
routinely applied by industry practitioners during resource evaluations. It is
common practice in the industry to allow for an upside view on long-term pricing
for the declaration of Mineral Resources in comparison to long-term price
assumptions used for Mineral Reserves or financial analyses.

Additional material lying outside of
the pit shell was shown to be potentially economic under the revenue and
underground mining cost assumptions and has also been included in the Mineral
Resource declaration.

Use of the pit shells and associated
sensitivities demonstrated that assumptions on pit slopes and pricing are, of
course, very important.

As usual under these conditions, there
is no guarantee that all declared Mineral Resources will eventually able to be
converted to Mineral Reserves.

17.4

Mineral
      Resource Statement

The estimation and classification of
the Mineral Resources conform to industry-best practices and meet the
requirements of CIM (2005). Table 17-27 summarizes the Indicated and Inferred
Mineral Resources for the 2009 resource model at the Gahcho Kué project. The
Qualified Person for the estimate is Ken Brisebois, P. Eng., an AMEC employee.
In this case, AMEC has elected to report the resources at a zero cut-off grade,
deeming that the kimberlite contacts can be considered to be the
potentially-mineable boundaries. AMEC cautions that Mineral Resources are not
Mineral Reserves and do not have demonstrated economic viability.

INTERPRETATION AND CONCLUSIONS

The Qualified Persons, as authors of this Report, have reviewed the data for the Project and are of the opinion that:

| |  | Mining tenure held by De Beers on behalf of the GKJV is valid and sufficient to support Mineral Resources. GKJV has taken appropriate steps to insure extension of the leases which will remain valid for several years. Surface rights have not, as yet,
been acquired, but this is not viewed by AMEC as a significant obstacle to further development of the Project. Those rights can be obtained by application to the Crown.

| |  | At this time, all of the permits required for exploration are in force. Permits required for exploitation were identified and the process for obtaining those permits defined.                                                                                                                                                                                                                                                                                                                                                                                                                                                                             
| |  | The geological understanding of the deposit setting, lithologies, and kimberlite type distributions is adequate to support Mineral Resource estimation. Understanding of diamond distributions within each kimberlite type is sufficient to support
Mineral Resource estimation.                                                                                                                                                                                                                                                                                                                                                                           
| |  | The style of mineralization is sufficiently understood to support Mineral Resource estimation.                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                             
| |  | Exploration programs completed to date are appropriate to the style of mineralization and adequate to support Mineral Resource estimation. Drill hole types and orientations are appropriate for the type of mineralization. Sampling and sample lengths
are appropriate for the type of mineralization. Core and cuttings logging meets and typically significantly exceeds industry best practices. Geotechnical work to date is appropriate for the stage of the project and type of mining planned. Collar and
downhole surveys were performed using industry-standard methods and instruments.                                                        
| |  | Analytical and diamond recovery procedures are sufficient to support Mineral Resource estimation. Macro and micro diamond extractions were performed using procedures standard to the industry. Geochemical samples were analyzed using standard
procedures and instrumentation. Density determination was performed using standard procedures, and the number of density data is adequate to support Mineral Resource estimation. Quality control during drilling, sampling, and sample analysis is
adequate and exceeds industry-standard practices. Quality control of diamond extractions consists of spikes using marked diamonds and tailings audits.
| |  | Sample and diamond security throughout the exploration process is excellent and consists of rigorous chain-of-custody procedures, multiple locks requiring at least two persons to open critical areas or containers, cameras in all plants and
processing areas, and dedicated security personnel at all plants and processing areas. Shipping of diamonds and diamond concentrates conforms to requirements of Kimberley Process chain-of-custody procedures.

| |  | Data storage and verification procedures are believed by the Qualified Persons to be adequate to support the geological interpretations and thus Mineral Resource estimation.
Data are stored digitally using appropriate database management software and is backed up periodically to insure against loss of data due to failure of a single computer or hard drive. Original data are properly stored as paper files and/or digital
files with appropriate backups. The project database undergoes periodic internal verification as well as periodic audits by external reviewers.
| |  | AMEC believes that sampling and data collection are adequate for proceeding into a feasibility-level assessment.                                                                                                                                                                                                                                                                                                                                                                                                                                                                      
| |  | Metallurgical testwork is appropriate for the stage of the project and is adequate to support Mineral Resource estimation. Bulk samples are processed using scaled-down equipment that allows collection of some of the processing parameters. Other
parameters were obtained from core specifically drilled for that purpose.                                                                                                                                                                                                                                                        
| |  | Estimations of Mineral Resources conform to industry-standard practices and meet the requirements of CIM (2005). De Beers (project operator), in undertaking the work, has applied industry-leading technologies. This is particularly the case with the
use of micro- diamonds in the estimation of 5034 North-East and Tuzo Mineral Resources.                                                                                                                                                                                                                                      
| |  | The refined micro-diamond estimation method developed and used for 5034 North-East and Tuzo is an important advance in technology allowing greater leverage of the total diamond content information that is contained in the micro-diamond data sets. It
should be recognized that the method is very complex and can be very susceptible to variability due to unrepresentative sampling. The operator should advance the research in terms of risk assessment on the key elements of the method.                                                                                   
| |  | The 2009 resource models reported herein are adequate for proceeding into feasibility- level project work.

RECOMMENDATIONS

The scientific and technical data on
the Gahcho Kué project is of sufficient quality and level of detail to support a
feasibility study, if a decision is made by the GKJV to proceed to a feasibility
study. AMEC recommends that the GKJV monitor market conditions to determine when
such a decision would be appropriate.
