Canadian junior mining company MDN recently announced the implications of a MMI (Mobil Metal Ion) soil sampling program that was conducted in April 2009 on its Isambara project in Tanzania. The programme confirmed that the southern area of that property can be described as a series of parallel goldbearing structures extending over a strike length of 1.3 km and having significant lateral extensions. These structures have been only partially drill tested.
With these new encouraging data, a drill program will be undertaken during the dry season at the beginning of July in this southern area, while two other MMI soil sampling programs will be conducted in the central and northern areas of the property with a view to defining additional drilling targets.
The Isambara project is characterised by a soil anomaly with a strike length of five kilometres divided into the three mentioned areas. To date, the main focus has been on the southern area in terms of drilling and analysis due to the ease of conducting all the preliminary work there.
At the heart of the southern area are two structures which have been shown to contain the highest goldbearing values, although they have barely been tested below a vertical depth of 40 metres. Based on all the drilling data obtained to date for the Isambara project, the highest goldbearing values appear to be located below the vertical depth of 40 metres.
In the MMI survey, 528 soil samples were obtained, including 26 blank samples to check field and laboratory procedures. Samples were taken every 25 metres along 12 lines spaced 100 to 800 metres apart across the gold-bearing structures of the southern area. The samples were prepared in the SGS laboratories in Mwanza, Tanzania, and shipped to the SGS laboratory in Toronto for analysis of the gold and 45 other elements using the MMI procedure.
Located 28 kilometres north of the Tulawaka gold mine, the Isambara project is wholly owned by MDN and covers a surface area of 40 km2.
