Montreal - Robex Resources Inc. (TSX-V: RBX) is pleased to announce the results of the drilling program on its Wili-Wili property located in West Mali. The results of this first campaign on the Fandou prospect confirm the great gold potential of the Wili-Wili property.

The Fandou Zone located at the south-western extremity of Wili-Wili, on the border of the Wili-Wili West permit (fig.1), is characterized by a strong gold anomaly measuring 2.8 km by 600 meters. At the centre of this anomaly, in the northern section, pits samples returned strong gold grades. An east-west trench, cut in the Fandou Zone graded 13 metres at 2.29 g/t Au and two pits dug out on this trench returned interesting values.

Drilling results, Fandou Zone

The following table shows the most significant results obtained on Fandou. Grades inferior to 1 g/t Au were not considered.

The goal for this drilling program was to better define and to enlarge the known mineralized zone on surface and at depth.

Drilling was carried out on a 100-meter-line-spaced-grid with east-west lines. The holes were spaced 60 meters from one another and oriented 090°N or 270°N with a -50° angle.

The lithologies encountered in this drilling program were mostly sediments although intrusives were intersected frequently. The sediments are shales, silts and graywackes. The shales are often graphitic and occasionally slightly pyritic. Rock fragments show a medium to strong schistosity. Intervals of intrusive rocks were intersected in several holes. These intervals vary in width from one to twenty metres.

Mineralization on Fandou is strongly tied to a shear zone, clearly observed on surface and in drilling and to quartz stockwerks and apparently associated sub-vertical veins. The absence of alteration and the scarcity of metallic minerals associated with the mineralization make its identification complicated on the ground.

Immediately east of the mineralized zone, and on its entire length, an intrusive felsic facies, moderately coarse and strongly seriticized was identified. This facies is not significantly mineralized but the intensity of its alteration and its spatial relation with the mineralized zone suggest a link between the two.

This first drilling program on Fandou is very encouraging. Almost all the holes intersected gold mineralization. Drilling has defined a mineralized zone stretching over 700 metres from north to south (fig.1).

In hole WR 139, interval 92 – 114m intersected 4,20 g/t Au over 22 metres, that is 12 metres at 3.61 g/t between 92 – 104m, followed by 9 metres at 5.37 g/t, between 105 and 114m. Note that this hole ended in mineralization. We can hope that mineralization continues below 115 metres.

The holes located more south have not returned significant results. The highest grade was 0.789 g/t.

These results motivate Robex to continue, as soon as possible, with a second drilling program on Fandou. This drilling program will be initiated early in the next exploration campaign planned to start in October 2007.

An IP gradient resistivity of Mamoudouya (fig. 2) shows a very structured ensemble of resistivity axis oriented N15° with subs-axis oriented N0° to N45°, probably linked to secondary faults oriented N45°. This ensemble of axis is framed on each side by two very defined directive zones, oriented N15°. Their directions coincide with major regional structures.

In 1992, the French BRGM (Geological Research Mining Bureau) intersected interesting gold grades in 6 trenches on Mamoudouya (see fig 2, Resistivity Survey)./span>

The following table shows the most significant results obtained on Mamoudouya. Grades inferior to 1 g/t Au were not considered.

Robex drilled 17 holes on Mamoudouya. The goal was to test the mineralized showings identified during soil geochemistry. The holes were spaced 70 metres from one another and were oriented 110°N. They were divided between two targets located 400 metres from each other. Seven holes were drilled on the northern target and 10 on the southern target.

The main lithology encountered on the drilling zone is granitic, moderately to coarsely grained. It is generally gray however occasionally pink and locally green resulting from epidotization A few chloritized aplitic intervals, less than 10 meters thick, were intersected. Sediments were intersected east of the northern target and west of the southern one. These sediments were graywackes, silts and shales. The last hole of the northern target intersects a level of graphitic shale. Gold is clearly associated to quartz veins with a very limited extension and continuity. An important N010° shear zone located immediately east of the drilling zone, however outside the anomaly, seems to control mineralization.

Results of the first drilling program on Mamoudouya were below expectations. Robex will analyse these results to evaluate the relevance of a second program.

A 4245-metre RC drilling program was carried out on Wili-Wili from April 20 to May 25, 2007. The drill holes were divided between the Fandou and the Mamoudouya gold prospects (fig.1): 18 holes totalling 2019 metres were drilled on Fandou and 17 holes totalling 1614 metres were drilled on Mamoudouya. In addition, 6 holes totalling 612 metres were drilled south of Fandou. All the holes were drilled at -500, perpendicularly to the sub-vertical layers. Deviation tests were carried out at the end of the holes..

Samples from the RC drilling were collected at metric intervals. The samples were sent to the Analab Laboratory, located in Kayes, Mali. They were analyzed by fire assay in 3-meter composite sections weighing 1.5 to 3 kg. The detection threshold was established at 0.005 g/t Au.

The quality of the analysis was tested by adding blanks (sterile), standards, and by duplicating samples. The numbers for these samples were distributed at random. The 3-meter long composite samples contained 5% of blanks and 5% of standards. Metric re-analysis included 5% blanks, 5% standards and 5% duplicates
