Robex: First drilling program on Wili-Wili intersects 22 m at 4.20 g/t Au



    MONTREAL, June 13 /CNW Telbec/ - 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.

    Fandou Zone

    The Fandou Zone located at the south-western extremity of Wili-Wili, on
the border of the Wili-Wili West permit (fig.1 -
http://robexgold.com/?page=19433105/lang=9), 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 on this trench also returned interesting values.

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

    Description of the program and interpretation of the results

    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 degrees N or 270 degrees N with a -50 degrees 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 alterations and the scarcity of
metallic minerals associated to the mineralization make its identification
complicated on surface.
    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 relationship with the mineralized zone suggest
a link between the two.

    Conclusion on the Fandou drilling program

    This first drilling program on Fandou is very encouraging. Almost all of
the holes intersected gold mineralization. Drilling has defined a mineralized
zone stretching over 700 metres from north to south (fig.1 -
http://robexgold.com/?page=19433105/lang=9).
    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
probably expect that mineralization continues below 115 metres.
    The holes located more to the south have not returned significant results.
The highest grade was 0.789 g/t.
    These results motivate Robex to continue 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.

    Mamoudouya Zone

    An IP gradient resistivity of Mamoudouya (fig. 2 -
http://robexgold.com/?page=19433135/lang=9) shows a very structured ensemble
of resistivity axis oriented N15 degrees with subs-axis oriented N0 degrees to
N45 degrees, probably linked to secondary faults oriented N45 degrees. This
ensemble of axis is framed on each side by two very defined directive zones,
oriented N15 degrees. 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 -
http://robexgold.com/?page=19433135/lang=9, Resistivity Survey).

    Description of the program on Mamoudouya

    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 degrees 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 degrees 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.

    Details and methodology of the drilling program on Wili-Wili

    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 -
http://robexgold.com/?page=19433105/lang=9): 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 -50 degrees, 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.
