Montreal - Robex Resources Inc (TSX-V: RBX)is pleased to announce that it has just completed two IP geophysical surveys on March 6, on the Fandou and the Mamoudouya zones of the Wili-Wili property located in West Mali. A 6,000-meter RC drilling program will begin in mid-April 2007.
The IP resistivity geophysical surveys were carried out using 100-meter line spacing and covered a 1.1 km by 1.5 km area (linear distance of 18 km) over the Fandou zone and a 1.5 km by 3.0 km area (linear distance of 48 km) over the Mamoudouya zone.
Fandou Zone
The IP resistivity geophysical survey over Fandou (fig. 1) shows 4 well-developed resistivity axis oriented N0° in an area located between a very resistive homogenous zone oriented N15° to the west, and a very conductive homogenous zone oriented N0° to the east.
These 4 resistivity axis superimpose upon the Au and As anomaly discovered in June 2006 (see PR 13-06). Resistivity axis N° 1 coincides in the Northern part with the N° 1 trench that returned 2.29 g/t Au over 13 meters in January 2007 (see PR 01-07) and where 5 pits had returned grades between 3 and 12 g/t Au over 9 meters in June 2006 (see PR 13-06).

Mamoudouya Zone
The IP resistivity geophysical survey over Mamoudouya (fig. 2) shows well-structured resistivity axis oriented N15° with sub-axis oriented N0° to N45°, most probably linked with secondary faults oriented N45°. This ensemble of resistivity axis is framed on each side by two well-defined conductive zones, oriented N15°. Their directions coincide with major regional structures.
In 1992, The BRGM (Geological and Mining Research Bureau) of Mali intersected the following values in 6 trenches over the Mamoudouya zone, represented in figure 2 of the IP resistivity geophysical survey:

The results appear relatively high considering the fact that the BRGM trenches were almost always located outside the most promising resistivity axis zones (see fig. 2).
Moreover, a large placer has been identified at the southern limit of the figure 2 map. It is topographically lower than the target zone which is also located on a topographic corridor oriented N15°, inclined to the South, that is towards the placer. Note that South of the BRGM trenching limits, the Mamoudouya valley is covered by relatively thick surface deposits that may have blocked geochemical signals.

Projected drilling
A 6,000-meter RC drilling program will begin in mid-April 2007 over the Fandou and Mamoudouya targets. We foresee first drilling the two zones following East-West oriented lines spaced at 400 meters apart. Depending on the results obtained from the first drill holes subsequent drilling will be undertaken with a spacing of 200 meters between the lines, then eventually at 100 meters.
Important bulldozer work is currently in progress to facilitate access to this property, which is very difficult to access, particularly south of the Falémé River.
Robex Resources Inc TSX-V: RBX is a Canadian mining exploration and development company focusing on Mali, West Africa. Mali is currently the 4th most important gold producing country in Africa. Robex' permanent exploration office is located in Mali, and is operated by senior geologists with an extensive experience in West African mining exploration. The team works on projects the Company already owns and is always on the lookout for new projects with favourable geology and a high potential for the discovery of world-class gold deposits. This permanent presence in Mali has allowed Robex to become one of the most active exploration and development companies in West Africa. In 2005, Robex was the third most important mining company operating in Mali in terms of investment in exploration.
