Fort a la Corne Joint Venture: Orion South Kimberlite large diameter drilling diamond grade reconciliation



    Stock Symbol: SGF: TSX

    SASKATOON, May 6 /CNW/ - George H. Read, P. Geo., Senior Vice President
Exploration and Development, is pleased to announce the reconciliation of
diamond grade results for the large diameter drilling ("LDD") mini-bulk
sampling with the underground ("UG") bulk sampling of the Orion South ("OS")
Kimberlite 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")). Shore has developed this reconciliation of LDD to UG
results to account for diamond breakage and diamond loss that occurs when
sampling using LDD. The results for each principal kimberlite unit sampled by
the LDD mini-bulk sampling and UG bulk sampling methods are shown in Tables 1
and 2, respectively.

    Table Notes

    -   Kimberlite Units: EJF: Early Joli Fou and LJF: Late Joli Fou
    -   EJF Inner and Outer based on geology and discussed below
    -   No UG bulk sampling occurred within the Cantuar, EJF Outer or Viking
        kimberlite units within OS
    

    The OS Kimberlite is one of the largest diamond bearing kimberlites in
the world, with a surface area totaling some 403 hectares situated within
claims of the FALC-JV. A resource estimate has not yet been determined for the
OS Kimberlite but kimberlite tonnage estimates, which are conceptual in
nature, were published in the SGF News Release of October 21, 2008. A
combination of UG bulk sampling and LDD mini-bulk sampling is required to
rigorously evaluate such a large kimberlite, which is buried under some 100
metres of glacial overburden. The UG bulk samples provide accurate diamond
grade and size distribution data which are considered representative of the
EJF Inner area and for assessing the potential for future mining. However,
economic and logistical parameters prohibit the collection of UG bulk samples
across the entire kimberlite, hence, the necessity for the use of a
combination of UG sampling and LDD. While the large UG bulk samples are
representative of the diamond population (grade and price), it is Shore's
assertion that diamond loss and diamond breakage occur (particularly of the
large stones) in the case of the LDD mini-bulk samples. In addition, on-site
testing has shown that diamond breakage increases as kimberlite competency
(hardness) increases. Therefore, Shore believes both the diamond grade
("cpht") and average price ($/carat) are underestimated for the LDD mini-bulk
samples.
    Shore contends that the easiest method of diamond grade determination for
the LDD mini-bulk samples, which accounts for diamond breakage and loss, is
the use of the processed tonnes, as opposed to the theoretical tonnes
(calculated from callipered hole volumes and density measurements). This has
been confirmed to Shore's satisfaction by the LDD diamond grade reconciliation
with UG grade for the Star Kimberlite that was recently presented in SGF News
Release of April 21, 2009. A more detailed discussion of these methods is
available in the technical presentation "Large Diameter Drilling Grade
Adjustment Factors for Resource Estimation in FALC Kimberlites", which is
available on the Company website at: www.shoregold.com.
    The EJF Inner and Outer Kimberlite Units have been identified by Shore
based on detailed kimberlite geology recorded from core logging of the pattern
drill program and diamond size data derived from LDD. 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
Inner Kimberlite Unit represents coarser grained EJF kimberlite and the EJF
Outer Kimberlite Unit includes finer grained EJF kimberlite. UG bulk and LDD
mini-bulk samples have shown that higher grades and larger diamonds are found
within the EJF Inner Kimberlite Unit. The UG bulk sampling was carried out
entirely within the EJF Inner Kimberlite Unit and is deemed representative of
this unit. A map is available on the Shore website (www.shoregold.com) that
indicates the EJF Inner Kimberlite Unit, the extent of the UG and the drill
hole (core and LDD) positions in OS.
    Senior Vice President Exploration and Development, George Read, states:
"The positive reconciliation of the diamond grade results from UG bulk
sampling and LDD mini-bulk sampling at OS, particularly for the target EJF
Inner kimberlite unit, provide a robust dataset for the calculation of a
resource estimate on OS. The LDD and UG grade data both show that the EJF
Inner at OS has a similar grade (approximately 18 cpht) to the EJF Inner of
the adjacent Star Kimberlite. The plus 10 carat diamonds recovered from both
the OS EJF Inner and Pense kimberlite unit are evidence of the coarse diamond
size frequency distributions of these kimberlites. The resource estimate on OS
is anticipated to be available in mid 2009."

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
and short form prospectus, and Shore's anticipation of and success in managing
the foregoing risks.
