Endeavour has been exploring in Mali since 2001. The Company has developed two principal land packages, one in Mali South and the other in Mali West which provide a comprehensive pipeline of projects and targets from early stage geochemical anomalies to National Instrument 43-101 compliant resources under feasibility study.
Mali South Land Package
In Mali South, Endeavour is working in joint venture partnership with Resolute Mining Ltd. on the Finkolo Gold Project on the Syama Gold Belt, as well as exploring several earlier stage properties on its own. A feasibility study was prepared by Resolute on the Tabakoroni deposit, which may provide satellite feed to the Syama Gold Mine (6 million ounces; Resolute Mining Limited, Denver Gold Forum, September 2010) which Resolute has put into production.
Mali West Land Package
In Mali West, Endeavour has over 500 kilometres that is contiguous with the Sadiola property of AngloGold Ashanti and IAMGOLD. The package covers the southern extension of the Mali West Shear Zone along strike of the 14 million ounce Sadiola Mine in the Kofi Formation as well as prospective ground to the west in the Keniebandi Formation. The most important gold deposits in Mali West (Sadiola, Yatela, Loulo and Tabakoto-Segala) all occur in rocks of the Kofi Formation in proximity to the eastern boundary of the Mali West Shear Zone.
In the Keniebandi Formation, Endeavour made a gold discovery at Diba in 2006. Diba is characterized by disseminated gold in a broad low grade (0.1 to 0.5 g/t) halo over 20 to 50 meters in thickness with narrow bonanza grade intercepts of 60-900 g/t over 1 to 2 meters. Mineralization is hosted in an arkosic sedimentary package which is open down dip to the east. A number of reconnaissance holes northwest of the main deposit intercepted wide zones of low-grade gold mineralization in a series of intrusive rocks.
The discovery at Diba and subsequent confirmation by diamond drilling of similar mineralization 10 kilometres to the south at Kobokotosou has provided sufficient results to drill targets at Keniebandi situated 30 kilometres south of Diba.
