INDEPENDENT QUALIFICATION REPORTS (NI 43-101)

Since 40 years from now, Areva/BU Mines (formerly Cogema) and its subsidiaries Somaïr (Société des Mines de l’Aïr) and Cominak (Compagnie Minière d’Akouta), has been mining many uranium ore bodies in the Arlit region, right on the edge of the saharien desert, 800 kilometers North of Niamey capital. The Somair operations are quarries and the Cominak one is an underground mine. The mineralization is originated from a fluvio-deltaïque d’âge carbonnifère and is contained within a sub-horizontal gréso-argileuse formation. The orebody survey has been done with a vertical destructive borehole based on a progessively densified square grid. Electric and natural radioactivity caracteristics were continually mesasured with core samplers along the boreholes. Those measures were converted into uranium grades en fonction d’une droite de correspondance établie dans quelques sondages caréttès de calage.

The approach to create the mined orebody resource model was relatively standard (blocks were put on a regular grid filling geological solids with values interpolated from composites that had the same size and contained within the same geological solid). However, two other features were considered in order to create the model:

1. the distribution interpolation (with equal conditioning) of each block content instead of a distribution mean
2. la « remise à plat » des composites et des blocs avant interpolation à partir de leur dénivelé par rapport à la surface d’un horizon repère à la base de la minéralisation.

The resource estimate accuracy, particularly with the production levels and the uranium metal above the teneur de coupure depends on an elaborated control application system ot the mineral in the pit ores. The first step of this system was the construction of a small geostatistical resource model for each tir dans la tranche minière à partir des mesures radiométriques dans les trous de tir. We then report, using a GPS, the limit of each mineralized block based on the model, in order to orientate mining operations. This ore selection is also guided by a trieur that controls the exposed material radiometry with a manual core sampler. This last sampler (the most important one) is located at one end of the pit, which than decide the final destination of the load.

Audit of 5 MANAGEM mines in Morocco

Mining activity is one of the main activities for the ONA Group since 1928. MANAGEM mining group, a subsidiary of ONA Group, has a total of six mining companies in hydrometallurgy in Morocco, one company in West Africa and two other service companies. MANAGEM has since develop a good expertise in mining development, by mining its deposits in Morocco, than in Africa, and after by diversifying its knowledge in hydrometallurgy. At the end of 2003, beginning of 2004, MANAGEM mandated Geostat to audit five of its mines resources and reserves in order to update classification with the new International standards.

Evaluation of the Douay Project owned by La Société d’exploration minière Vior inc. - Open Pit Pre- feasibility Study – Phase 1

Géostat was hired to estimate the resources and the reserves of the Douay and Douay West properties, wholly owned by La Société d’exploration minière Vior inc. (Vior) in the Douay Township. For this study, Vior provided all the technical data (database in electronic format and a set of cross-sections on paper and files). Geostat’s qualified engineer and geologist visited the site in April 2005. At the time of this visit, core from previous campaigns and core drilled in 2005
were examined. Samples were taken for validation directly from the core boxes stored on the project site. The drilling sites were visited, and the sampling procedures inspected.

The resources and reserves reported in the document were compliant with current standards as outlined in National Instrument 43- 101. The study was completed at the pre-feasibility stage for the upper part of the Douay West gold deposit. The Douay and Douay West properties are located 50 km southwest of Matagami and 120 km north of Amos, in Abitibi. The Douay property is easily accessible via paved and gravel roads. The Douay and Douay West properties are located along the Casa Berardi - Douay – Cameron fault zone, the most important gold structures in the Northern Volcanic Zone of the Abitibi sub-province. All the rocks of the Douay project are metamorphosed to the greenschist facies. The Douay West mineralized zones are located 5 to 30 metres north of a graphitic fault zone. The zones are oriented approximately 120º (geographic north) with a dip of 60º to 80º towards the south. The mineralized zones have variable thicknesses, from a few centimetres to more than 30 metres. The vertical extensions (100 to 400 metres) are more important than lateral extensions (20 to 100 metres). The top part of the mineralized zone is expected to be mined by open pit. The deeper mineralization could be mined using a ramp or a shaft. The resources were estimated using such a scenario. Douay-West deposit: Open pit resources are limited between the topography and a vertical depth of 90 metres while material below 90 metres is considered a different cut-off is applied.

Costa Rica - Vannessa

Geostat has received a mandate from Vannessa Ventures Ltd from Calgary to review the resources estimation of the Crucitas gold deposit in Costa Rica. This project was drilled extensively by Placer Dome in the 1990’s. After receiving the approval of their Environmental Impact Statement in 2005, Vannessa is moving forward with the project, with the objective of developing a mine as soon as possible. PJ Lafleur from GSII visited the site in October 2005 to prepare to write a technical report according to National Policy 43-101 adopted in 2001.

Maroc / Morocco - Managem

Geostat has started its semi-annual follow up of audits of the mines in the Managem Group of ONA in Morocco initiated at the beginning of 2004 on an annual basis. PJ Lafleur from Geostat has visited the Akka gold mine (AGM) and the Imiter silver mine (SMI) in July 2005 to start the first semiannual selective follow up. Geostat is pleased to report that these gold and silver mines progressively and decisively apply Geostat’s recommendations based on the National Policy 43-101 adopted by the Canadian Stock Market in 2001 to facilitate the financing of exploration and mining companies. Canada is the main source of financing of this economic sector in the world.

Geostat prepares technical report for Ariane Gold

Ariane Gold hired Geostat to prepare a technical report for its properties in French Guiana. The company needed a NI43-101 conforming report for its stock exchange lis-ting application. As part of its assignment, Geostat visited the site located near the capital city of Cayenne. Check samples were taken to validate the existing ones. The resource estimates available prior to Ariane`s acquisition were not NI 43-101 compliant since they were not categorized. Hence, Geostat developed a new resource model and classified the resources appropriately. Geostat is proud to have cooperated with Ariane and wishes success to this newly formed company.

September

During the month of December 1995, We audited Inco's resource calculations of their Goro nickel deposit as part of the feasibility study undertaken by SNC-LAVALIN Inc. of Montreal, Quebec. An audit differs greatly from conventional resource modeling in that, rather than carrying out the calculations ourselves, we analyze the Client's data, procedures, calculations and results and submit our conclusions and recommendations. Goro is a lateritic nickel deposit located in the southern part of New Caledonia with economic nickel grades located in both the limonite and saprolite horizons of the orebody. Suggestions were made particularly with regard to the use of geostatistics. In general, the audit confirmed the resource model developed by Inco.
