Vancouver, March 4, 2008: Gitennes Exploration Inc (TSX-GIT)
is pleased to report significant silver and gold intercepts from the ongoing
drilling programme at its 100%-owned Urumalqui project in north central
Per�.
Six new holes have been completed, with
results received for the first five, and drilling continues. All of the holes
reported here test the main Urumalqui Vein structure deeper at its southeastern
end. Drilling shows that while the vein is narrow on surface
(1
metre),
it thickens with depth. Significant vein intercepts from the current programme
include:

Silver equivalent is calculated using a ratio of
50:1. The Company has not undertaken metallurgical tests to determine the
recovery of gold and silver. Therefore the silver equivalents values stated here
assume a recovery of 100%.
Vein widths and the silver and gold grades
reported are comparable or higher than those from previous drill programmes. The
intercepts in the southeastern portion of the Urumalqui vein show that the
structure remains open at depth and along strike to the southeast. At depth the
Urumalqui vein maintains both continuity and grade and remains a relatively
simple quartz-andularia vein with only rare traces of sulphide minerals. These
deeper intersections have significantly increased the project�s resource
potential. The Urumalqui vein has now been traced by drilling over a strike
length of 1,400
metres and has been intersected to depths of over 200
metres below surface.
As reported previously by the company (November
20th, 2003), a mineralized gold halo surrounds the main Urumalqui
vein. Deeper drilling during this latest programme has found that the width and
strength of this �gold envelope� mineralization increases at depth, with
significantly higher silver grades than previously identified. Recently
completed holes URU08-39 and URU08-40 intersected the Urumalqui vein and its
envelope at deeper levels from surface than previously encountered by the
Company.

Gold and silver mineralization in the gold
envelope in holes URU08-39 and URU08-40 is accompanied by locally strong chlorite-pyrite alteration with zones of moderate silicification. The holes
ended in mineralization and the zone remains open in all directions. This zone
of alteration is first observed in hole URU08-39 at a depth of
144 metres
(hangingwall to the vein) and is more pervasive from 235 metres downwards, with
remarkably consistent low-grade gold and silver mineralization.
Company geologists suspect that the zone is
�evolving� at depth into a larger hydrothermal system that is not epithermal in
nature and pre-dates the veins that have been the target of our drilling to
date. It is interesting to note that a comparable style of gold mineralization
was encountered in drill holes (2004) from the Mariscala vein, located one
kilometre west. The intervening area has not been drilled.
Hole locations: Hole URU08-36
was collared 60
metres north-northwest of hole URU04-29
(2.2 metres @
149.29 g/t Ag) at an inclination of -45�. The vein was cut at a vertical depth
of 48.5
metres below surface. This hole, together with URU08-37
and URU08-38, was aimed at testing the continuity of the vein between hole
URU04-29, the most southeasterly hole drilled to date, and hole URU04-16 (1.4 metres @
296.4 g/t Ag), collared 250
metres to the northwest.
Hole URU08-37 was collared 80 metres west-southwest of hole
URU08-36 at an inclination of -55�. The vein was cut at a vertical depth of
157 metres
below surface. The hole was aimed at testing the continuity of the vein
progressively towards the northwest from hole URU04-29.
Hole URU08-38 was collared 45 metres closer towards the vein
than URU08-37 at an inclination of -55�. It aimed to cut the vein at a shallower
depth than URU08-37 in order to test the continuity of mineralization along the
plane of the vein. It cut the vein at a vertical depth of 78 metres below surface.
Hole URU08-39 was collared 189 metres west-southwest of hole
URU04-38 and aimed to cut the vein in between earlier holes URU04-30
(1.03 metres
@ 135 g/t Ag) and URU03-13 (2.83
metres @ 237.60 g/t Ag), spaced 100 metres apart. URU08-39 was
drilled at an azimuth of 023� and an inclination of -45�. The vein was cut at a
vertical depth of 207
metres below surface, the deepest vein intercept to
date.
Hole URU08-40 was collared 100 metres northwest of hole
URU08-39 and 30
metres behind hole URU03-13 (2.83 metres @ 237.60 g/t Ag) along
the same section. The aim was to
undercut hole URU03-13 to test the vein�s grade and thickness continuity at
depth. The hole was drilled at an inclination of -50�. The vein was intersected
at a vertical depth of 158 metres below surface.
Drilling at Urumalqui is under the supervision
of Alvaro Fernandez-Baca, P.Geo. Analytical services and fire assays are provided by ALS Chemex Laboratories in Lima. The technical information in this
release has been reviewed by J. Blackwell (P.Geo), a Qualified Person as defined

Analytical data from the gold envelope, an updated drill plan and a
longitudinal section has been posted to our website at
