Star Diamond Project: Updated NI 43-101 Mineral Resource - 23 percent increase in indicated tonnes and carats

    Stock Symbol: SGF: TSX

    SASKATOON, Feb. 27 /CNW/ - George H. Read, P. Geo., Senior Vice President
Exploration and Development, is pleased to announce an updated NI 43-101
compliant Mineral Resource estimate for the explored portion of the Star
Kimberlite ("Star"), which supersedes the previously published resource
estimate. This updated resource estimate includes the diamond results of eight
additional large diameter drillholes: 5 holes on Star and 3 holes on Star
West, totaling 1,368 metres of drilling with 306 metres in kimberlite. This
updated resource estimate also incorporates additional diamonds recovered from
concentrate and tailings audits as well as the geology's influence on the
diamond distribution within Star. The updated 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
152 million tonnes at a grade of 14 carats per hundred tonnes ("cpht") and
Inferred Resources of 26 million tonnes at a grade of 12 cpht. This updated
resource estimate increases the indicated tonnage and contained carats for
Star by 23 percent when compared to the initial resource estimate published in
June 2008 (SGF News Release June 9, 2008 and Technical Report July 22, 2008,
which are available on and Tables 1 to 3
summarize the details of the updated NI 43-101 Mineral Resource as prepared by

    Table 1. Mineral Resource Estimate for the Star Kimberlite including the
Star Diamond Project (100% Shore) and Star West (60% Shore, 40% Newmont).
Reported Kimberlite Units: Cantuar, Pense, Early Joli Fou (EJF), Mid Joli Fou

    The EJF Inner and Outer Kimberlite Units 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
Star and their volcanological features that form the Star Kimberlite crater.
The EJF Inner represents coarser grained EJF kimberlite that occurs within the
volcanic cinder cone and the EJF Outer includes finer grained EJF kimberlite
that lies on and outside the cinder cone. Underground bulk sampling and large
diameter drilling ("LDD") have shown that higher grades and larger diamonds
are found within the EJF Inner Kimberlite Unit. The underground bulk sampling
of the EJF is deemed representative of the EJF Inner and also produced an
average grade of 17 cpht for the EJF, similar to the resource estimate for 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 Star is constrained using a floating-cone economic open pit shell. The
Mineral Resources reported in Tables 1, 2 and 3 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 4.

    Diamond values for this resource statement are based on the March 2008
High modeled prices determined by WWW International Diamond Consultants Ltd
("WWW") and are detailed in Table 5. The High modeled prices were also used in
the June 2008 resource estimate and the use of the High modeled prices in this
resource update facilitates comparison. The diamond prices used in this
resource update will be reassessed for use in the reserve estimate scheduled
for completion in late 2009.
    WWW states "It should be noted that current diamond prices have been
substantially reduced by the present world financial crisis with rough prices
falling from their peak in August 2008 by around 40%, dependent upon size and
quality. That said, and acknowledging the high degree of uncertainty around
the diamond market and other commodities, WWW's view of future supply demand
fundamentals is positive in relation to current prices. However, we do not see
prices returning to March 2008 levels for some considerable time."

    As a test of the sensitivity of the Star resource to market fluctuations,
the resource model was also run with the pit shell using the WWW Low and Model
price scenarios. The results suggest that the Star 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

    In addition to the Mineral Resource estimate determined by P&E, a further
60 to 70 million tonnes of the Star Kimberlite is designated a 'potential
mineral deposit', as detailed core logging, whole rock geochemistry,
geophysical and density measurements confirm the geological continuity from
the Inferred Resource into this part of the kimberlite, which is contained
within the 276 million tonnes originally defined in the geological model for
the Star Kimberlite (Shore News Release Oct 17, 2006). The 60 to 70 million
tonne potential mineral deposit is conceptual in nature and is not a resource
estimate. It is uncertain if additional exploration work would lead to the
kimberlite presently included in the potential mineral deposit being upgraded
to a resource category.
    The Star Kimberlite is one of the largest diamond bearing kimberlites in
the world, with a surface area totaling some 352 hectares situated within
claims of both the Star Diamond Project (100 percent Shore) and the adjacent
Fort a la Corne Joint Venture (FALC-JV: 60 percent Shore and 40 percent
Newmont Mining Corporation of Canada Limited ("Newmont"), referenced in this
news release as "Star West"). The Mineral Resource estimate prepared by P&E
includes kimberlite volume, density and tonnage data collected during the
surface and underground core drilling program comprising 285 surface core
holes (18,259 metres of kimberlite) and 211 underground core holes (15,933
metres of kimberlite), diamond and tonnage data from underground bulk sampling
(66,988.29 dry tonnes, 10,597.58 carats and 81,773 stones) and diamond and
tonnage data from the mini-bulk samples recovered from the extensive LDD
program on Star (97 holes, 11,495.01 processed tonnes, 1,416.69 carats and
15,987 stones). This resource estimate uses a 1.0 millimetre bottom diamond
size cut-off and considers all kimberlite above 71 metres above sea level or
to a depth of 350 metres below surface.
    Senior Vice President Exploration and Development, George Read, states:
"The publication of this updated NI 43-101 Mineral Resource estimate for the
Star Kimberlite is a significant milestone in the evolution of the Star
Diamond Project. This updated resource estimate has increased the carats
contained in the Indicated Resource by 23 percent and we believe that this
increase will have a significant effect on the future economics of the Star
Diamond Project. This updated resource estimate will be used in determining
the NI 43-101 compliant Mineral Reserve estimate for Star. The reserve
estimate will include a reasonable estimate of the operating cost and capital
of a potential mine at Star. We are on track to deliver the reserve estimate
on Star by late 2009."
    Shore commissioned the NI 43-101 Mineral Resource estimate and related
Technical Report for the Star and Star West properties 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

    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 exclusive owner of the Star Diamond Project. The Star West property 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.
