The sections are oriented NE-SW and their numbers progress toward the south-
east. True widths are not known.
(i)= drilled from within the open pit.


The main mineralized body previously known below the open pit was located between sections -400 and -200. Only small lenses were known outside the main body. The 2005 and 2006 drilling allowed us to confirm both the continuity and the grade of the main body mineralization and defining new mineralized lenses in its peripheral zones. These results also confirm the particularly high grade nature of the auriferous mineralization at depth.

These drilling results below the Tulawaka Mine were provided to the partners by the project operator who supervised the program. The samples were analyzed at the SGS Laboratory in Tanzania, certified in accordance with international standards. This information was reviewed by Dominique Fournier, Ph.D., that acted as qualified person in accordance with NI 43-101.

The Tulawaka Project is a joint-venture between MDN Northern Mining (30%) and Pangea Goldfields (70%), a wholly owned indirect subsidiary of Barrick Gold Corporation and project operator through its own Tanzanian subsidiary Pangea Minerals Ltd. MDN Northern Mining is an exploration company of which its head office is located in Montreal, Canada. In Tanzania, as well as the 30% participating interest in the Tulawaka Gold Mine, MDN Northern Mining holds a controlling participation in 20 prospecting licenses located within a 50-kilometre radius from the mine.
