GITENNES REPORTS COPPER AT TOTOROKO, STARTS DRILLING AT
URUMALQUI
Vancouver, January 30, 2008; Gitennes Exploration Inc
(TSX-GIT) is pleased to
update shareholders on its on-going copper, silver and gold exploration projects
situated in Peru.
At its 100%-owned TotoRoko
Project, located in southern Peru, the company completed 1000 metres of core
drilling in seven holes. The highlight was hole TR07-07 which
returned:

Hole TR07-07 was collared
on the north flank of Cerro Lomas Orjo in an area of highly altered and locally
well-mineralized volcanic rocks. The hole was located based upon the geology of
the zone; there is no induced polarization (IP) anomaly present. The entire hole
(133.3
metres)
was within variably altered and mineralized rocks, with the upper
63 metres being of interest. This interval, from 11.2
to 63.20
metres,
returned an average grade of 0.47%
copper.
Secondary copper mineralization occurs as both oxide (malachite and
chrysocolla) and sulphide (chalcocite and bornite). Within the highest grade
interval, massive chalcocite and disseminated bornite were observed.
Other results: Drill hole TR07-01 was collared to test the
Canta�a silver-gold vein
structure, 1,100 metres northwest of hole 7. The hole encountered an unexpected
wide zone of intense fracturing, silicification, alteration and quartz-carbonate
veining over a core length of 113
metres (true width estimated to be 60 metres). Traces of galena,
tetrahedrite and pyrite were noted in core, though grades are subeconomic. The
strength of the Canta�a
structure, which has been traced over a length of 800 metres, was an unexpected,
positive development. The Company�s geologists have recently returned to the
property and completed a series of soil geochemical sampling profiles (MMI -
Mobile Metal Ions) across the zone in order to further test this target which
coincides with a large, unexplained IP anomaly.
Drill holes TR07-02 to 06 were located on the principal
target, Cerro Totorcco, 1,190 metres west of hole 7. Drilling difficulties were encountered,
and only two of the five holes reached their intended target (a sheet-like IP
anomaly approximately 150 to 200
metres below surface). Drilling encountered thick zones of
highly silicified and fractured volcanic rocks as well as abundant intrusive
porphyry dykes, and the drill was unable to complete the holes as intended. The
two deepest holes, TR07-03 and 04, intersected a corridor of dense porphyry dyke
swarming. Thin screens of pyritic tuff and highly altered, copper-bearing rocks
are present, suggesting that the zone was present, but is now extensively
�diluted� by post-mineral dykes. Examples of the mineralization that was
encountered in Cerro Totorcco include:
Hole TR07-02: 10.5
metres (from 36.00 to 46.50 metres) with 0.40% Cu;
and
Hole TR07-06: 4.55
metres (from 24.40 to 28.95 metres) with 0.25% Cu.
Since completing the December drill programme, crews have
returned to TotoRoko to complete the MMI sampling and to scout additional drill
sites. Additional work is planned later in 2008, once the road access in the
region is assured. Current weather in this area of
Peru is
unusually rainy, a condition that may last into April.
Work at
TotoRoko is supervised by A. Fernandez-Baca (P.Geo). Analytical services are
provided by ALS Chemex in Lima, Peru, check analyses by CIMM Peru S.A.
Urumalqui
A Diamond drill programme is underway at the 100% owned
Urumalqui Property in northern Peru. Urumalqui is a low-sulphidation epithermal
vein prospect. The property was drilled twice previously (2003-early 2004) by
the Company, returning favourable intercepts of silver and gold mineralization.
The Company has undertaken an internal review of the
project. A Peruvian geologist with many years experience in this type of deposit
was engaged to help steer the exploration towards attaining enough technical
information to complete a resource estimate and undertake a preliminary economic
scoping study. The recommended programme of Diamond drilling (minimum
2,000
metres), underground sampling, and metallurgical testing
has been accepted and is now underway.
The initial objective at Urumalqui is to
block-out a 1,000-metre long segment of the main vein to a depth of
200 metres
below surface. Previous drilling, most of which is within 100 metres of surface, suggested
that a weighted average grade of 6.49 ounces per tonne silver and
1.68 g/t gold may be realized over an average vein width of 3.70 metres (based upon 17 holes
of 23 holes drilled, reported following).

It
is hoped that the new holes will extend the higher grade portions of the vein
further to the southeast and to depth, resulting in a significant improvement to
the project�s potential.
