to prepare an independent mineral resource evaluation and Technical
Report for the Amisk Gold Project. This mineral resource evaluation is
based on historical drilling completed by Saskatchewan Mining
Development Corporation (“SMDC”) between 1983 and 1989 and Claude
between 1996 and 1998 as well as recent core drill holes drilled by the
Joint Venture during 2010. The entire database comprises 299 drill
holes (53,507 metres), of which 21 (5,657 metres) were drilled by the
Joint Venture in 2010. Resource evaluation was undertaken in

successful integration of our 2010 exploration with historic drilling
to generate this geological model and open pit resource estimate is the
culmination of an aggressive 12 month exploration program and is a
major milestone for the Amisk Gold Project and Claude Resources.
Moving forward at Amisk, we will focus on expansion of the open pit
resource, preliminary metallurgical, engineering and economic studies,
as well as an evaluation of the underground potential. Furthermore,
with the support of a continued strong gold price, strong working
capital, planned initiation of Phase II underground drilling at
in the first quarter 2011 and improving economics at our Seabee Gold
Project, Claude is well-positioned to capitalize on the current gold
market and execute on its strategy of discovering, developing and
producing gold in established belts proximal to existing
The Amisk Gold Deposit is hosted within a rhyolite flow-dome complex and
overlying pyroclastic tuffs of the Amisk Volcanic Assemblage,
Greenstone Belt. High grade gold and silver mineralization is hosted
within a series of moderately to shallowly-dipping, pyrite +/-
chalcopyrite-sphalerite-tetrahedrite-galena-bearing sulphide vein
systems. High grade vein systems are typically flanked by wide
intervals of low grade disseminated and stringer sulphide
mineralization within a broad sericite alteration envelope. A detailed
plan map and representative cross sections outlining the conceptual
open pit and resource model are presented on Claude’s website (www.clauderesources.com).
The breakdown of mineral resources for each modeled domain, using a
cut-off grade of 0.4 grams of gold equivalent per tonne for the Amisk
Gold Deposit are outlined in Table 2 below.

Footnotes to the Mineral Resource Statement:
Mineral resources for the Amisk Gold Deposit are reported at a cut-off
of 0.40 grams of gold equivalent per tonne using a price of U.S.
per ounce of gold and U.S.
$16per ounce of silver inside a conceptual
pit shell optimized using metallurgical and process recovery of
eight-seven percent, overall ore mining and processing costs of U.S.
$15per tonne and overall pit slope of fifty degrees. All figures are
rounded to reflect the relative accuracy of the estimates.
Mineral resources are not mineral reserves and do not have demonstrated
economic viability. There is no certainty that all or any part of the
mineral resource will be converted into mineral reserves. The resource
evaluation work was completed by a team of resource geologists under
Glen Cole, P.Geo., a full time employee of SRK. Mr.
Cole has sufficient experience, which is relevant to the style of
mineralization and type of deposit under consideration and to the
activities undertaken to qualify as a Qualified Person as defined by
National Instrument 43-101.
The mineral resources reported herein have been estimated in conformity
with generally accepted CIM “Estimation of Mineral Resource and Mineral
Reserves Best Practices” guidelines and are reported in accordance with
Canadian Securities Administrators’ National Instrument 43-101.
The construction of the Amisk mineral resource model was the product of
collaboration between Claude and SRK staff. The capture and validation
of historical exploration data was initiated in
compiled a digital database containing 299 boreholes (53,507 metres).
Rigorous quality control and validation procedures, inclusive of twin
holes and quartering of historic core, were completed by Claude
Resources. The database also includes recent drilling information on
the Amisk Gold Deposit to
December 31, 2010. SRK audited the procedure
and visited the site and is of the opinion the data are reliable for
the purpose of resource estimation.
SRK was engaged in
October 2010to complete an evaluation of mineral
resources reported herein. Mineral resources were estimated using a
geostatistical block modeling approach constrained by mineralization
wireframes. Block size was set at cubes five metres in size.
Underground excavations were removed from modeled blocks. Block gold
grade was estimated by ordinary kriging from sourced capped composite
data. Search neighbourhood and estimation parametres were adjusted
based on variography results. Two estimation runs were completed and
grade estimates verified using other estimators. The mineral resource
model was validated visually on section by section and elevation by
elevation basis. Quantile-quantile plots comparing resource block and
capped composite data show the usual smoothing effect of kriging
particularly at higher grades, but confirm that the block model is
representative of the informing data.
Analysis of the cumulative probability plots for individual resource
zones determined that capping of high-grade assays to limit their
influence during grade estimation was necessary. Probability analysis
was completed on individual resource domains with capping values
ranging from 95(th) to 99(th) percentile.
The resource reported herein includes an adjustment to account for
underground development related to a bulk sample completed by SMDC in
A Technical Report supporting the Mineral Resource Statement will be
filed on SEDAR (www.sedar.com) within 45 days.
The mineral resources for the Amisk Gold Project are sensitive to the
selection of cut-off grade. Table 3 presents the quantity and grade
estimates at a range of cut-off grades inside the conceptual pit shell
considered for reporting the Mineral Resource Statement. A cut-off
value of 0.4 grams of gold equivalent per tonne was selected based on
optimization results and benchmarking against similar deposits.

Note: The reader is cautioned that the figures in this table should not
be misconstrued with a Mineral Resource Statement. The figures are only
presented to show the sensitivity of the block model estimates to the
selection of cut-off grade.
A team of personnel from Claude and SRK was involved in the preparation
of the Mineral Resource Statement for the Amisk Gold Deposit, including
resource evaluation was reviewed by SRK, with Mr.
full time employee of SRK and independent from Claude assuming
professional responsibility. Mr. Cole has reviewed the content of this
for the Amisk Gold Project. The Company has implemented a rigorous
Quality Assurance and Quality Control program to ensure best practices
in sampling and analysis of drill core. Drill core was halved and
samples averaging 1.5 to 2.0 metres were submitted to TSL Laboratories
control procedures have been implemented including the use of blanks,
standards and duplicates. Core samples were analyzed by a 30 gram gold
fire assay with an atomic absorption, conventional gravimetric and/or
screen fire techniques.
