The Amisk Gold Property is a gold and silver exploration property located in the province of Saskatchewan 20 kilometres southwest of Flin Flon, Manitoba. The property hosts the Amisk Gold Deposit, the past-producing Monarch Mine as well as a large number of gold occurrences and prospects. At 13,900 hectares, this gold and silver exploration property one of the largest land positions in the prolific Flin-Flon mineral district. Claude owns a 65 percent interest while St. Eugene Mining owns the remaining 35 percent; Claude is the operator of the Joint Venture. The Flin Flon mining district where the Amisk Gold Project is located is home of Hud Bay Minerals. Hud Bay Minerals has several projects in the area such as the 777 Mine, Trout Lake Mine, a zinc plant and concentrator. Also the Konuto Lake Mine located near the Amisk Gold Project operated from 1998 to 2005. The Flin Flon mining district has state of the art infrastructure as well as a mining friendly community.

Fall Drill Program A total of 20 holes and 6,480 metres were drilled during the fall program. The remaining 6 holes are presented below. The program tested from surface to in excess of 600 metres depth and was designed to expand the limits of the Amisk Gold deposit as well as infill within the northern and eastern portion of the deposit.
Highlights of the drilling include 6.24 grams of gold per tonne and 23.5 grams of silver per tonne over 12.00 metres and 3.39 percent zinc and 0.91 percent lead over 1.81 metres in hole AL-11-318 and 1.95 grams of gold per tonne and 14.9 grams of silver per tonne over 18.95 metres in AL-11-319. Mineralization intercepted in the drilling is consistent with the current resource model and is associated with a sequence of quartz porphyritic, rhyolitic lapilli tuffs and basaltic tuffs and argillite hosting disseminations, stringers and semi-massive intervals of pyrite, sphalerite, galena, tetrahedrite, pyrrotite and chalcopyrite.
Drill hole AL-11-319 confirmed continuity of gold mineralization within the southeastern portion of the deposit as well as demonstrated the potential for expansion to the east and southeast. Four holes were completed evaluating the continuity of the system to depths in excess of 600 metres. Hole AL-11-318 intercepted significant mineralization at depth with intercepts of up to 71.74 metres at 0.60 grams of Au per tonne as well as a 1.81 metre interval of 3.39 percent zinc and 0.91 percent lead in the hangingwall, 250 metres west of the deposit.
"The 2011 Amisk drill program confirmed mineralization within the current resource model and to depths of up to 600 metres. There is potential for growth of the resource base at depth and to the southeast and east. The presence of significant grades of zinc and lead in the hangingwall will be the focus of follow-up drilling in 2012," stated Brian Skanderbeg, Vice President Exploration.

Note: Intervals noted are intercepted width not true width, have been calculated using a 0.3 g/tonne cut-off and are uncut. True width is variable between 60 and 100 percent of drilled width. They may include internal dilution intervals of up to 10 metres. NSI – No Significant Intercept Figure 1: Amisk Gold Project Plan Map Figure 2: Amisk Gold Property, Flin Flon Regional Location Map Positive Metallurgical Testwork at Amisk Gold Project The initial metallurgical testing indicates that gold and silver mineralization is amenable to conventional cyanide leaching. Results from testing on three composite samples from the Amisk Gold Deposit have returned an average of 89.4% recovery for gold, ranging from 85.2% to 91.7% and an average of 80.8% recovery for silver, ranging from 66.4% to 92.8%. Finer grinds resulted in higher recoveries for all metals, with peak recoveries for the medium grade composite of 91% for gold and 92.8% for silver. Details of the metallurgical results are presented in Table 1.
Based on the work done and described herein, Amisk ore should be treated by conventional SAG and ball mill grinding to achieve a final grind not finer than 80% passing 75 microns. Present mill sizing was done at 75 microns to correspond with maximum Au and Ag recoveries. Further economic studies and more tests should be done to optimize the grind required. It is suggested that this optimized grind will lie between 72 and 117 microns. The correct process to recover gold and silver is direct whole ore cyanidation with carbon-in-pulp technology used to recover the leached gold and silver values. Reagent consumption in cyanidation was reasonable. About 1 kg/t of NaCN (sodium cyanide) and 0.5 kg/t of lime will be required. Further cyanidation test work was recommended to identify optimum operating conditions.
In addition to cyanidation, flotation and gravity concentration were also evaluated. Rougher and scavenger flotation yielded gold and silver recoveries of 80.1% and 92.8% respectively in a pyrite concentrate containing 9.1% of the weight. The corresponding sulphur recovery was 99%. Flotation is not recommended as there are insufficient base metal values present to justify flotation. Gravity concentration was also not recommended.
In addition to metallurgical test work, SAGDesign Communition tests were completed on the three composite samples. Results demonstrated moderate ore grindability in the SAG mill and soft-to-moderate hardness in the ball mill. Testing for the three composite samples showed low variability, with an average SAG pinion energy requirement for a 1.7 mm product of 10.07 kWh/t and a Bond Work Index of 10.71 kWh/t.
The initial metallurgical and grinding mill engineering tests were conducted on 215 kg collected from half split core. Representative core intervals from eight drill holes were combined to create low, medium and high grade composites that assayed 0.50, 0.85 and 1.68 g/t gold and 7.4, 9.2 and 8.4 g/t silver. This mineralization is representative of the Amisk Gold Deposit and consists of trace to 10% disseminated pyrite and stringers with minor sphalerite, chalcopyrite, galena and tetrahedrite hosted in a sericitized quartz porphyry.
![]() Amisk Gold Project National Instrument 43-101 Claude and St. Eugene commissioned SRK Consulting (Canada) Inc. (“SRK”), 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 January 2011 on eight domains that comprise the Amisk Gold Deposit. The mineral resource statement reported herein is the culmination of that work. There is potential for expansion of the resource both along strike and at depth below the conceptual pit bottom. Highlights of the Amisk Mineral Resource estimate are presented in Table A.
Brian Skanderbeg, Claude’s Vice-President Exploration, stated that “The 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 Madsen 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 infrastructure.” 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 B below. 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.

Exploration Results Winter 2011 Program A total of 8 holes, 3,234 metres, were completed and assayed from the 2011 winter drill program. The program tested from surface to in excess of 600 metres depth and was designed to expand the limits of the Amisk Gold Deposit as well as infill within the northern portion of the deposit. "This latest drill program has intercepted the target stratigraphy and significant intercepts up to 400 metres southwest, to the north and at depth, below the conceptual pit outline," stated Brian Skanderbeg, Vice President Exploration.
