Fort a la Corne Joint Venture: Orion South NI 43-101 Mineral Resource - Indicated: 84 million tonnes and 12 million carats - Inferred: 98 million tonnes and 13 million carats

    Stock Symbol: SGF: TSX

    SASKATOON, Sept. 10 /CNW/ - George H. Read, P. Geo., Senior Vice
President Exploration and Development, is pleased to announce the NI 43-101
compliant Mineral Resource estimate for the explored portion of the Orion
South Kimberlite ("OS"), which is located at the southern end of the Orion
Kimberlite Cluster within the Fort a la Corne Joint Venture ("FALC-JV": 60
percent Shore Gold Inc. ("Shore") and 40 percent Newmont Mining Corporation of
Canada Limited ("Newmont")). This resource estimate has been prepared by an
independent Qualified Person ("QP") from P&E Mining Consultants Inc. ("P&E").
The Mineral Resource estimate includes Indicated Resources of 84 million
tonnes at a grade of 13.83 carats per hundred tonnes ("cpht") and Inferred
Resources of 98 million tonnes at a grade of 12.83 cpht. Table 1 summarizes
the details of the NI 43-101 Mineral Resource as prepared by P&E. The lower
proportion of Indicated Resources of overall tonnes reported at OS, when
compared to the Star Kimberlite, is due to a significantly smaller underground
bulk sample when compared to the Star Kimberlite (23,468 tonnes from OS versus
75,436 tonnes from Star) and a smaller large diameter drilling (LDD) program
at OS (62 holes on OS versus 96 holes on Star).

    Table Notes

    (1) Mineral resources are accumulated within an optimized floating-cone
        pit shell.
    (2) Mineral resources which are not mineral reserves do not have
        demonstrated economic viability. The estimate of mineral resources
        may be materially affected by environmental, permitting, legal,
        title, taxation, socio-political, marketing or other relevant issues.
    (3) The quantity and grade of reported inferred resources in this
        estimate is conceptual in nature. There is no guarantee that all or
        any part of the mineral resource will be converted into a mineral
    (4) 1 millimetre bottom diamond size cut-off assumed.
    (5) Resources are reported at a C$4.94 cut-off.

    The OS Kimberlite is one of the largest diamond bearing kimberlites in
the world, with a surface area totalling some 403 hectares, situated within
the FALC-JV claims. The Mineral Resource estimate prepared by P&E includes
kimberlite volume, density and tonnage data collected during the surface
drilling programs comprising 149 core holes (15,517 metres of kimberlite), and
62 LDD holes (7,920 metres of kimberlite), diamond and tonnage data from
underground bulk sampling (23,468 dry tonnes, 2,346 carats and 15,248 stones)
and diamond and tonnage data from the mini-bulk samples recovered from the LDD
program on Orion South (62 holes, 9,580 processed tonnes, 1,039.67 carats and
10,356 stones). This resource estimate uses a 1.0 millimetre bottom diamond
size cut-off and considers all kimberlite above 20 metres above sea level or
to a depth of approximately 430 metres below surface.
    The Inner (vent proximal) and Outer (vent distal) Kimberlite Units of the
EJF and Pense are based on detailed kimberlite geology recorded from core
logging of the pattern drill program. Core logging information is combined
with whole rock geochemistry data, geophysical and density measurements to
identify the constituent kimberlite lithologies within OS and their
volcanological features that form the OS Kimberlite crater. The EJF and Pense
Inner Kimberlite Units represent coarser grained EJF and Pense Kimberlite that
occurs within the volcanic cinder cone and the EJF and Pense Outer Kimberlite
Unit include finer grained EJF and Pense Kimberlite that lies on and outside
the cinder cone. Underground bulk sampling and LDD have shown that higher
grades and larger diamonds are found within the EJF and Pense Inner Kimberlite
Units. The underground bulk sampling of the EJF is deemed representative of
the EJF Inner Kimberlite Unit.
    An essential component of the Mineral Resource estimate relies on the
reconciliation of the diamond grades from the underground samples with those
calculated for the LDD samples. The LDD sampling method underestimates the
true diamond grade and price due to limited sample size, diamond breakage,
diamond loss and dilution of LDD grade by overburden falling down LDD holes.
Detailed analysis of diamond results from LDD and underground bulk sampling
has been undertaken, and reconciled with kimberlite geology, defined by core
drilling, in order to define rigorously constrained factors that are applied
to diamond grade results from LDD.
    CIM standards and securities commission disclosure regulations require
that a resource can only be declared on a mineral deposit which has
"reasonable prospects of economic extraction". The reported mineral resource
for OS is constrained using an optimized floating-cone pit shell. The Mineral
Resources reported in Table 1 comprise the kimberlite that is constrained
within the floating-cone pit shell and exceeds the economic cut-off as
determined by the parameters in Table 2.

    Diamond prices used in this resource statement are based on a valuation
by WWW International Diamond Consultants Ltd. ("WWW") using their March 2008
price book. The High scenario modeled prices determined by WWW are used in the
Resource estimate and are detailed in Table 3. High scenario modeled prices
for the Star deposit were also used in the February 2009 resource estimate and
the August 2009 reserve estimate for the Star Kimberlite and the use of the
High scenario modeled prices in this OS resource estimate facilitates
    WWW estimates that diamond prices are presently approximately 10 to 15
percent lower than March 2008 levels. P&E have utilized the WWW diamond
valuations based on March 2008 prices and, although diamond prices have since
dropped by 10 to 15 percent, changes in the Canadian $/US $ exchange rate of
some 15 percent in favour of project economics have occurred since March 2008,
thereby supporting the use of the March 2008 High diamond price valuation.

    Kimberlite          Parcel Price  Model Price  Minimum Price  High Price
    Lithology   Carats   (US$/carat)   (US$/carat)  (US$/carat)   (US$/carat)
    EJF       1,400.38       $98           $121         $100          $166

    As a test of the sensitivity of the OS resource to market fluctuations,
the resource model was also run within the pit shell using the WWW Minimum and
Model price scenarios. The results suggest that the OS resource is relatively
insensitive to moderate diamond price fluctuations. The variations in tonnes,
grade and carats for the three WWW diamond price scenarios are listed in Table

               Inferred        98.0       12.8         12.6

    In addition to the Mineral Resource estimate determined by P&E, a further
90 to 100 million tonnes of the OS Kimberlite is designated a 'potential
mineral deposit' by Shore, as detailed core logging, whole rock geochemistry,
geophysical and density measurements confirm the geological continuity of
kimberlite material from the Inferred Resource into this part of the
kimberlite, which is contained within the 333 million tonnes originally
defined in the geological model for the OS Kimberlite (Shore News Release
October 21, 2008). The 90 to 100 million tonne potential mineral deposit is
conceptual in nature and is not a resource estimate. It is uncertain if
additional exploration work will lead to the kimberlite presently included in
the potential mineral deposit being upgraded to a resource category.
    Senior Vice President Exploration and Development, George Read, states:
"This NI 43-101 Mineral Resource estimate for the OS Kimberlite proves the
potential of the FALC-JV to contain diamondiferous kimberlites of substantial
value. Shore has recently shown that an economic diamond mine with the world's
largest diamond processing plant (40,000 tonnes per day) is feasible at the
Star Kimberlite (Shore News Release August 27, 2009) and any additional
resources estimated within the FALC-JV will significantly augment the
economics of a diamond mine."
    Shore commissioned the NI 43-101 Mineral Resource estimate and related
Technical Report for the Orion South property and, as such, the Technical
Report is the sole responsibility of Shore. Newmont did not participate in the
preparation, supervision or review of the work associated with this exercise
and takes no responsibility for the content or information included in the
Technical Report or this press release.
    Shore anticipates publication of the Technical Report as soon as it is
available, within the regulated 45 day period after this news release. Shore
is the operator of the FALC-JV, which is held by the Fort a La Corne Joint
Venture between Shore as the operator and 60 percent owner and Newmont as the
owner of a 40 percent interest.
