(2) Areas have been calculated from concession coordinates provided in the arrêtés and concession applications. The Ségala Mining Permit contains the Ségala Main, Ségala NW Deposits, Dar Salam, Moralia, Kenieba (Sansanto) and NE Orpailleur Deposits. The Tabakoto Mining Permit contains the Tabakoto NE, NW, Dioulafoundou, Tabakoto South and Dabo Deposits, and the Kéniéba Exploration Permit contains the Djambaye II Deposit. The Tabakoto Mining Permit and the Ségala Mining Permit are held in the name of Ségala Mining Corporation S.A. (“Semico”). The two exploration permits, Toubikoto and Manianguiti, are also held in the name of Semico. The shares in Semico are distributed between Avion Resources (Mali) Ltd. (80%) and the Government of the République of Mali (20%). Avion Resources (Mali) Ltd. is a direct wholly-owned subsidiary of Endeavour. On January 8, 2010, Endeavour (then Avion) announced the acquisition of a 100% interest in the Kéniéba Concessions held by Great Quest. The Kéniéba Concessions are located adjacent to the south and west sides of the Tabakoto Mining Permit and comprise the Kéniéba (Sansanto), Kéniéba Est and Comifa Concessions totaling approximately 32 km 2 . Under the terms of the acquisition agreement, the Corporation has agreed to make future contingent payments of up to $2.1 million in the event that it produces more than 400,000 ounces of gold from the Kéniéba Concessions, payable upon realizing each additional 50,000 ounces of production. If production from the concessions exceeds 600,000 ounces, Endeavour would be required to make payments of up to a further $1.4 million to complete its obligations under this agreement. There are currently no material environmental liabilities associated with the Tabakoto Gold Mine. The Corporation completes a small amount of site rehabilitation annually and has recently completed a review of its asset retirement obligations. Accessibility, Climate, Local Resources, Infrastructure and Physiography The Tabakoto Gold Mine is located in the southwest corner of the Republic of Mali, a land-locked country in the northwest corner of Africa, bordered to the north by the Sahara Desert and by the countries Sénégal, Mauritania, Algeria, Burkina Faso, Niger, Cote D’Ivoire and Guinea. 0% 0%
Air access to the Tabakoto property is possible by charter aircraft from Bamako, 360 kilometres to the east, to Kéniéba. The flight from Bamako to Kéniéba is about an hour. Kéniéba is accessible via a new paved road that extends from Bamako to Dakar. Depending on conditions, the drive takes from five to six hours to complete. Endeavour operates daily road shuttles to and from Bamako for personnel and small freight. An all-weather laterite access road branches west from the Route Nationale, south of Tabakoto, for approximately 1.2 km to the Tabakoto mine and campsite. A variety of dirt and laterite roads crosscut the mine area to allow access to virtually all corners of the property. The climate in the Kéniéba District is tropical with only two seasons: (i) a rainy season from June to October and (ii) a dry season from November to May. The average temperature range in western Mali is between 18°C and 43°C. During the hottest portion of the summer months, temperatures vary between 25°C and 43°C. In the winter months of December and January, the temperature ranges between 18°C and 35°C. The wet season generally moderates the average temperature. Peak temperatures of 54°C have been noted. Local infrastructure is poor with few supplies or support services available in the Kéniéba area. Most equipment and supplies are imported from Europe to the port of Dakar in Sénégal and shipped by rail to Kayes then by truck to the property area, or directly by truck from Dakar. The state telephone company MaliTel and France’s Orange operate cellular telephone services in Kéniéba area. At the project site, a local cellular telephone network has been established with both wireless and LAN inter/intra-net systems. All mines in the region are still reliant on diesel generated electricity. In addition, water supply to the processing plant is primarily sourced from the Falémé River, and is supplemented by recycled water from the tailings dam and other sources. The Kéniéba District is at an elevation of 120 metres above sea level. Low rolling peneplained plateaus cut by moderately well-developed drainage systems cover most of the property. Rising above the plateaus in some areas are long ridges capped by hard ferruginous laterite crusts (cuirrasse) that extend for several kilometres. Immediately to the east of the property there is the prominent west facing Tambaoura escarpment formed by sandstone cliffs that rise to over 350 metres in elevation. The district of Kéniéba is largely vegetated by tall grass and wooded savannah. Abundant seasonal streams crisscross the area and flow southward into the Doundi River and then westward into the Falémé River that forms the Mali-Sénégal border. Land use consists of subsistence farming and grazing of domestic animals. Crops usually consist of maze, millet, rice, peanuts and melons History Local villagers have reported that the original Tabakoto deposit was located by villagers in the early 1950s. At that time, the site was apparently a small scale alluvial mining site. Chronological summaries of historical exploration activities in the Kéniéba district and on the Tabakoto, Ségala and Fogala-KoutilaDioulafoundou permits catalogue the extensive quantity of exploration work that has been completed over the properties. Between 2004 and 2007, there were no geological and drilling exploration reports focused on the Tabakoto deposit that served as precursor to current mine development. Avion reinitiated geological and drilling work in 2008 for the purpose of mine development and to discover new resources. 33
