Project Summary: Viyonza

Owner

Co-ownership with Tanzanian Royalty Exploration, with MDN able to earn up to a 65% interest.

Location

Located 160 km to the SW of Mwanza, the second largest city in Tanzania, and 18 km to the north of the Tulawaka mine (Barrick 70%, MDN 30%).

Area

The project consists of one prospecting license of 25.72 km² and two licenses whose renewals are pending totaling 77.12 km².

Geology and mineralization

The Viyonza showing was discovered by MDN in 2005 approximately 15 km to the north of the Tulawaka mine plant.  The original showing measured 400 m long by 300 m wide and was tested by drilling from 2005 to 2007.  The mineralization is associated with steeply-dipping sulphide-bearing quartz veins hosted by shear zones that cut gabbro and tuff near a granodiorite intrusion.  Visible gold occurs in holes NTDD-03 and NTDD-04.  400 metres from the main zone in Block A, holes NTRC-70 and NTRC-71 cut several mineralized zones one of which graded 11.6 g/t Au over 1.0 m.

• The Viyonza project is located in the Rwamagaza greenstone belt, host of the Tulawaka (> 748000 oz Au) and Buck Reef (± 1.8 million oz Au) mines.
• Two gold zones were discovered, one in block A and another in block D.
• Block A gold is associated with quartz veins and sulfides in an intensely-sheared gabbro intrusion an in surrounding volcanic tuff.
• Gold mineralization inside Block D is associated with quartz veins hosted by mafic tuff.
• Gold anomalies detected by several soil surveys are aligned along the northern contact of the volcanic rocks with the granites.  This contact transects the property for more than 6 km and joins the A and D blocks.
• The Viyonza property forms the western extremity of the gold anomaly that constitutes the 30-km-long Viyonza-Mnekezi lineament.  This lineament coincides with the northern contact of the volcanic belt with the granitic rocks.  The Tulawaka mine occurs in a similar geologic environment but along the southern contact of the belt.
