    Stock Symbol: SGF: TSX

    SASKATOON, Aug. 27 /CNW/ - George H. Read, P. Geo., Senior Vice President
Exploration and Development, is very pleased to announce the positive results
of the Pre-Feasibility Study ("PFS") on the Star Kimberlite, which includes
the 100 percent Shore Gold Inc. ("Shore") owned Star Diamond Project and Star
West, which is that portion of the Star Kimberlite that falls within the
adjacent Fort a la Corne Joint Venture (FALC-JV: 60 percent Shore and 40
percent Newmont Mining Corporation of Canada Limited ("Newmont")). The PFS was
led by P&E Mining Consultants Inc. ("P&E"), an independent and internationally
recognized geological and mining consulting firm. A number of other
independent consulting firms also provided their study results to Shore and
P&E for use in developing the PFS. All currency amounts are quoted in Canadian
Dollars, unless otherwise stated.
    President and CEO, Kenneth MacNeill, states: "Shore is very pleased with
the positive results of the Star PFS. These prefeasibility numbers confirm the
potential for a world class diamond mine in east central Saskatchewan and
provide every reason to move this Project to the Feasibility Stage. Shore
Management and Directors acknowledge the extensive and diligent work that has
been performed by Shore's technical team and associated consultants to reach
this most important milestone in the successful evaluation of the Star Diamond

    The Star Diamond Project PFS Highlights Include:

    -   Probable Mineral Reserves of 171 million tonnes at a weighted average
        grade of 12 carats per hundred tonnes ("cpht") containing 20 million
        carats at a weighted average price of $265 per carat (US$225);
    -   Total diamond production of 20 million carats over a 12 year total
        mine life;
    -   Robust project economics over a 12 year mine life due to proximity to
        infrastructure (hydroelectric power, paved highways, water and
    -   A pre-tax base case Net Present Value ("NPV") of $474 million (using
        a 7 percent discount rate) for an Internal Rate of Return ("IRR") of
        12 percent and an after-tax NPV of $291 million with an IRR of
        10 percent;
    -   Pre-production capital cost of $1,487 million with a total capital
        cost of $1,646 million (including direct and indirect costs) over the
        life of the mine and an initial capital payback period of 5.2 years;
    -   P&E recommendation that Shore advance the Star Diamond Project to a
        Feasibility Study based on the positive PFS.

    Senior Vice President Exploration and Development, George Read, states:
"The Star PFS and Reserve Estimate show that Star can be economically
developed as a stand-alone diamond mine. The determination of a resource
estimate on the neighbouring Orion South Kimberlite within the FALC-JV is
currently underway. A resource estimate on Orion South has the potential to
significantly augment the economics documented in this Star PFS. The NI 43-101
compliant Technical Report that summarizes the PFS and mineral reserve
estimate will be available on the Shore website and SEDAR within 45 days of this news release."

    Star Diamond Project Prefeasibility Study Results

    The Star Diamond Project PFS cash flow model is based on developing the
Star open pit, processing plant and infrastructure as a stand-alone project
and assumes the Project has a 4 year long pre-production development period
followed by a 12 year production period. The model assumes on-site
construction would start in Q4-2010 with ore production commencing in mid-2014
and ending in mid-2026. The financial evaluation in the PFS is done on a 100
percent basis and does not separate the cash flows of the joint venture

    Economic Analysis

    The cash flows utilize a 1 percent annual compound diamond price
escalation rate starting in year 2010. Pre-tax and after-tax results based on
1 percent annual diamond price escalation are shown in Table 2 for comparison.
Shore anticipates that diamond prices will increase at a rate faster than
costs due to long-term diamond supply/demand fundamentals.

    Economic risks were assessed using base case cash flow sensitivities to
recovered grade, diamond prices, $/US$ exchange rate, capital costs and
operating costs. Each of the sensitivity items were independently adjusted up
and down by 10 percent, 20 percent and 25 percent to project the impact on the
NPV at a 7 percent discount rate. The NPV of the Project after each
sensitivity item was adjusted by 75 percent, 80 percent, 90 percent, 110
percent, 120 percent and 125 percent of the base are presented in Table 3. The
sensitivity analysis shows that the Star Diamond Project is most sensitive to
$/$US exchange rate fluctuations.

    Mineral Reserve Estimate

    The Star Diamond Project Mineral Reserve Estimate (Table 4) was derived
from the Mineral Resource $/tonne block model. Utilizing operating costs for
mining, processing and G&A and engineered pit slopes, a pit optimization was
undertaken to derive a pit shell for design purposes. This five phase pit
design includes vehicle access ramps, conveyor ramps and berms. The pit design
surface is used to determine which mineralization contained within it from the
Resource model is to be converted to reserves by $/tonne value cut-off and the
inclusion of appropriate ore losses and dilution. All reserves estimated for
the Star Kimberlite are in the Probable category and no additional evaluation
is required prior to mining. These Probable reserves are estimated from the
Indicated resource category only. The pit design includes the mining of
approximately 26 million tonnes of kimberlite in the Inferred resource
category containing some 3 million carats; however, the financial model does
not recognize any revenue associated with the recovery of these additional
carats as insufficient exploration work was carried out to move these into the
reserve category. An additional 60 to 70 million tonnes of kimberlite in the
potential mineral deposit category also lie outside the current PFS pit
design, which defines the mineral reserves and resources in the Star
Kimberlite. The potential mineral deposit is conceptual in nature, is not a
resource estimate and it is uncertain if additional exploration work would
lead to the kimberlite presently included as potential mineralization being
upgraded to any resource category. This potential kimberlite mineral deposit
cannot be relied upon when considering any project economics.

    Table Notes

    1.  The Mineral Reserves have a 1 millimetre bottom screen size cut-off.
    2.  The above Mineral Reserve was defined with a process cost of $3.29/t
        and G&A cost of $1.65/t resulting in a cut-off of $4.94/t which is
        equivalent to 1.86 cpht.


    An In-Pit Crush and Convey system will be used to pre-strip the waste
materials and expose the kimberlite ore. Conventional hydraulic excavators and
haul trucks will be used to mine the ore and to remove associated overburden
and waste rock. The ore and waste rock will be separately sized in the pit and
then conveyed to the processing plant ore stockpile and to the waste
management area, respectively. The PFS assumes that the initial overburden
pre-stripping work will be done utilizing Shore's work force, with the
assistance of an earthmoving contractor(s), using conventional scrapers,
excavators, haul trucks and ancillary equipment.

    Processing Plant and Infrastructure

    The Star Diamond Project PFS assumes that the processing facility will be
located 1.2 kilometres north of the Star pit edge. The facility is designed to
treat 40,000 tonnes of kimberlite per day employing autogenous milling as the
primary diamond liberation method, followed by dense media separation and
x-ray with scavenging grease for final diamond recovery. Extensive ore
dressing investigations on drill core and pilot scale testing on underground
bulk samples, coupled with detailed computer simulations, show that autogenous
milling of the Star Kimberlite will result in efficient and low cost diamond
liberation, while reducing diamond breakage in the process.
    Electrical service will be provided to the site by a 16 kilometre
transmission line at 230 kilovolts, connecting to the existing provincial grid
to the southeast of the site and crossing the Saskatchewan River. Site road
access will be accomplished by utilizing the provincial grid road to the
northern boundary of the Fort a la Corne forest, and then upgrading the
existing forest roads to accommodate higher traffic flows. Other support
facilities include an administration/change house building, warehouse,
maintenance shops, fuel storage, water treatment facilities and processed
kimberlite containment areas.
    The total direct capital costs for the process plant and infrastructure
are estimated at $612.7 million, while indirect costs, including engineering,
procurement and construction management, freight, commissioning, vendor
support, first fills and owner's costs are estimated at $188.4 million. An
additional $178 million is estimated for contingency at 22.2% of direct and
indirect costs.

    Environment, Permitting and Closure

    The Environmental Impact Assessment (EIA) process was initiated in
November 2008 by Shore with the submission of a Project Proposal (now referred
to as an initial environmental evaluation) to the Saskatchewan Ministry of
Environment (MoE) and Federal agencies for a combined Star-Orion South Diamond
Project (the "Project") recognizing the distinct potential of a combined
mining and processing project. In response to Shore's Project Proposal, the
province, in conjunction with the Federal government, developed draft project
specific guidelines to outline the requirements of the EIA. These draft
guidelines were released for comment on July 11, 2009. Shore intends to
prepare the Environmental Impact statement (EIS) for submission as soon as
practical. The EIS will confirm the Project footprint, will identify potential
environmental issues, propose mitigative measures and provide an assessment of
the Project. The proposed mine layout is estimated to disturb approximately
3,000 to 4,000 hectares, or 2.3 to 3.0 percent of the FALC forest, and would,
among other impacts, result in changes to several small waterways, require
crossing of water courses, require construction and management of overburden
and processed kimberlite storage areas and require management of mine water.
    Shore currently has all necessary licences and permits for present
operations. The permits that will be required for the construction and
operation of the proposed mine will be applied for following Ministerial
approval upon conclusion of the EIA. The submissions for these applications
are expected to generally take up to 90 days for review and approval.
Additional permits will be required from the Federal government, including
authorization from the Department of Fisheries and Oceans to allow anticipated
changes to fish and fish habitat, permits from Natural Resources Canada for
the explosives storage site and authorizations from Environment Canada and
Transport Canada.
    Site reclamation and closure, including the removal of site facilities,
will be performed at the end of the life of mine in accordance with
Saskatchewan's Reclaimed Industrial Sites Act. The conceptual closure plan is
based on a target end land use of self-sustaining forest.

    Community Relations

    Community Open House meetings conducted by Shore in furtherance of the
Star Diamond Project were successfully launched in February, 2009 with local
communities showing overwhelming support for the Project. The Open House
meetings are part of the Environmental Impact Assessment process under way as
a result of the filing of the Project Proposal. A description of community
engagement activities will form part of the Environmental Impact Statement
which will be submitted to the Saskatchewan Ministry of Environment at the
conclusion of the Assessment. Development of a mine will bring substantial
economic development to the cities of Prince Albert, Melfort and other
communities in the surrounding district. The mine is expected to provide
direct employment for some 500 people annually over its 12 year operating

    Project Timeline

    The PFS assumes the following Project timelines:

    -   Feasibility Study completion by the end of February 2010;
    -   A production decision by March 31, 2010;
    -   Permitting activities to support a 2010 construction start;
    -   Processing plant commissioning within four years after construction
        permit approvals.

    Caution Regarding Forward-looking Statements

    This news release contains forward-looking statements as defined by
certain securities laws, including the "safe harbour" provisions of the
Ontario Securities Act and the United States Private Securities Litigation
Reform Act of 1995. The words "may," "could," "should," "would," "suspect,"
"outlook," "believe," "plan," "anticipate," "estimate," "expect," "intend,"
and words and expressions of similar import are intended to identify
forward-looking statements, and, in particular, statements regarding Shore's
future operations, future exploration and development activities or other
development plans containing forward-looking statements.
    These forward-looking statements are based on Shore's current beliefs as
well as assumptions made by and information currently available to it and
involve inherent risks and uncertainties, both general and specific. In making
the forward-looking statements contained in this news release, Shore has
utilized diamond valuations completed in March, 2008 and although diamond
prices have since dropped by 10 to 15 percent, changes in the Canadian $/US $
exchange rate have improved by approximately 15 percent, thereby supporting
the use of the March, 2008 high diamond price valuation. Risks exist that
forward-looking statements will not be achieved due to a number of factors
including, but not limited to, developments in world diamond markets, changes
in diamond prices, risks relating to fluctuations in the Canadian dollar and
other currencies relative to the US dollar, changes in exploration,
development or mining plans due to exploration results and changing budget
priorities of Shore or its joint venture partners, the effects of competition
in the markets in which Shore operates, the impact of changes in the laws and
regulations regulating mining exploration and development, judicial or
regulatory judgments and legal proceedings, operational and infrastructure
risks and the additional risks described in Shore's most recently filed Annual
Information Form, annual and interim MD&A. Shore's anticipation of and success
in managing the foregoing risks could cause actual results to differ
materially from what is anticipated in such forward-looking statements.
    The Project schedule includes an estimated 4 year long pre-production
period and a 12 year long mine production phase followed by mine closure.
These durations were developed based on currently projected time lines for
power distribution line design and construction; equipment and material
procurement, deliveries, assembly and commissioning; environmental assessment
and review; technical studies including a recommended feasibility study for
the Project; permitting and other factors. The assumed dates and timing of
milestone events such as the date for corporate approval to proceed with the
Project, the mid-2014 commencement of ore production, and the mid-2026
cessation of operations were based on available information, and the time
lines between the assumed dates are reasonable based on the envisaged Project.
There is a possibility the assumed dates such as the date for corporate
approval to proceed with the Project will shift forward into the future for a
multitude of reasons including, but not limited to, longer than originally
projected time lines for environmental assessment and public consultation, and
engineering, procurement, construction and commissioning.
    The cash flow model includes estimates of future federal, provincial and
local government taxes. Federal and provincial (Saskatchewan) corporate income
taxes payable on pre-tax cashflows were estimated based on future tax rates
substantively enacted as March 31, 2009. The value of future property and
school taxes were estimated based on the current understanding of the levels
of local government taxes paid by similar scale mines in Saskatchewan. Diamond
royalty payments were estimated based on an assumed diamond royalty structure
generally consistent with terms and royalty payments of diamond royalty
regimes already in place in the Northwest Territories and Ontario, Canada. The
Government of Saskatchewan is developing its diamond royalty regime and may
issue it for public review later this year but this may occur later than
anticipated. Depending on the details of the Government of Saskatchewan's
diamond royalty structure, it has the potential to affect the projected
economics of the Project. Additionally, both the base case and modified base
case cashflows utilize selected estimated deductions available to the Project
from unclaimed costs carried forward for tax purposes (e.g. tax pools)
including Canadian exploration expenses and Canadian development expenses.
    The estimated capital and operating costs (+/- 25 percent estimation)
were derived from first principles and supported by budget quotations and/or
cost information derived from relevant cost databases and/or contractor
quotations, and assumptions. The base case excludes capital contingencies. The
modified base case includes a $178 million plant and infrastructure
contingency but no mine contingency in consideration of the envisaged mining
methodology and identified opportunities for improvement, including potential
IPCC operation improvements and reduced overburden stripping costs and
utilizing ore stockpiling to enable the plant to process at its 14.6 Mpta ore
capacity instead of processing 14.2 Mtpa ore as currently proposed. In
concept, a plant feed rate of 14.6 Mtpa ore could reduce the operating life of
the mine by about 0.3 years and reduce the total estimated cost of
duration-dependent cost components, such as General and Administration costs,
over the operating mine life.
    The results of the PFS presented in this Technical Report are based on
developing the Star Diamond Project ("Project") as a standalone project and do
not assess the potential economic viability of the Orion South deposit.
    Although management considers the assumptions contained in
forward-looking statements to be reasonable based on information currently
available to it, those assumptions may prove to be incorrect. When making
decisions with respect to Shore, investors and others should not place undue
reliance on these statements and should carefully consider the foregoing
factors and other uncertainties and potential events. Unless required by
applicable securities law, Shore does not undertake to update any
forward-looking statement that may be made.
