VANCOUVER, Jan. 30 /CNW/ - 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:
-------------------------------------------------------------------------
From....to (metres) Core length % Copper Silver (g/t)
(metres)
-------------------------------------------------------------------------
33.55 - 63.20 29.65 0.78% 5.1
-------------------------------------------------------------------------
Incl. 54.00 - 59.35 5.35 3.9% 22.1
-------------------------------------------------------------------------
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 Cantana 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 Cantana 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.
