VANCOUVER, March 1 /CNW/ - Gitennes Exploration Inc. (TSX-GIT) is pleased
to report on the results of recent chip sampling of zinc prospects on the
Tucumachay and Titimina Properties in central Peru. Zinc mineralization is
hosted in the same Pucara Group (Condorsinga Formation) limestone and dolomite
that host gold mineralization elsewhere on the property. Mineralization is
carbonate replacement type, occurring as pipes, lenses, mantos and veins
within zones of fractured, dolomitized limestone adjacent to a regional
contact. Barite is common, and "zebra-texture" banded barite-sphalerite mantos
are observed in the Korimachay-Ushcumachay prospects. Numerous old workings
and pits are present at most of the prospects, dating from pre-1980 small-
scale (less than 100,000 tons) mining.
On the Tucumachay Option, five prospects have been examined, none have
been previously drilled. All require detailed mapping and sampling.

The Saturno prospects are the only targets on the west flank of the
regional anticline. They are located along a set of steeply-plunging folds.
The western limb of one fold contains numerous pits, adits and showings over a
500 metre length, all confined to a 20 to 35-metre thick interval of dolomite.
Other showings are at a similar stratigraphic position, though repeated by
folding up to 200 metres further east. Mineralized lodes occur as pipes and
bedding-parallel replacements. These initial samples are from old pit walls
and surface showings, all samples are variably oxidized. The sample grading
17.98% zinc, 1.47% lead and 10.5 ounces per ton silver over 15 metres also
grades 0.65 g/t gold.
Pamela, Ushcumachay, and Korimachay are on the eastern limb of the
regional anticline and within a 2,500 metre-long panel of collapsed, faulted
and variably dolomitized limestone. Zebra-textured barite - sphalerite units
can be traced through distances of over 70 metres, accompanied by well-
developed sparry dolomite and units of disseminated sphalerite in dolomite.
All zones are variably oxidized, and several old dumps at Ushcumachay are
notable for large blocks of secondary, very high grade (more than 20%) zinc
mineralization. A 10 metre thick unit of dolomite breccia at Korimachay was
traced for several hundred metres, and where sampled, returned 7.86% zinc and
2.8 oz/t silver. A prominent igneous dyke and two remarkable stockwork zones
of manganese vein breccias that are up to 40 metres wide and 600 metres long
occur in this area; these features may be related to the mineralizing event.
Similarly, Delta Zinc is a zone of highly faulted and disrupted dolomite
and dolomite breccia that has numerous zones of discolouration and
mineralization over a minimum distance of 300 metres. Large blocks of oxidized
mineralization after sulphide were noted at one adit. Despite a strong sense
of fracture-control, mineralization occurs within a set interval of dolomites
(50 to 80 metres thick) that may be traced a further 1,000 metres north onto
the wholly-owned Titimina property where the Alpha and Beta Zinc prospects are
located.

At Alpha Zinc, a central fault hosts a 20 - 30 metre wide zone of heavy
smithsonite and hydrozincite that is flanked by bedding-parallel lenses of
sparry dolomite with remnants of oxidized sphalerite extending 10 to 30 metres
on either side. The Company previously announced (July 20, 2005) a chip sample
result at Alpha grading 20.59% zinc and 35.6 g/t silver (1 oz/Ton) across 26.8
metres. This sample was collected across the central fault, 50 metres west of
these current samples. Beta Zinc, located 300 metres south, comprises a series
of steep zones of massive sphalerite and galena in calcite veins.
Sampling and detailed mapping of all these targets is continuing. Further
work may result in some of these prospects being slated for drilling in the
upcoming third phase of drilling at the La Nariz and Encantada gold zones.
Work at Tucumachay and Titimina is under the supervision of James Foster

The Titimina Project is owned 100% by Gitennes.
The Tucumachay Project is held under option from Inmet Mining
Corporation. Gitennes may earn its 100% interest in the project by incurring
additional expenditures of (approximately) US$ 600,000 before December 31,
2008. Once Gitennes has completed 12,000 metres of drilling Inmet may earn-
back a 60% interest in Tucumachay by investing three times Gitennes' total
project-related expenses to that point.
