VANCOUVER, July 30 /CNW/ - Gitennes Exploration Inc. (TSX-GIT) is pleased to report that on-going exploration at the Company's TotoRoko Property continues to return highly encouraging results. Highlights include:
- New zones of copper, gold and silver mineralization found;
- Cantana, a cross-cutting silver-gold structure, returning up to
1,230 g/t silver and 3.26 g/t gold;
- Lomas Orjo, a further extension of the zone of outcropping secondary
copper mineralization to the southeast;
- Multiple parallel zones of alteration, mineralization and brecciation
found, target width increases.
Mineralization at TotoRoko spatially associated with igneous intrusive rocks that occur along major faults related to the continent-scale Incapuquio (Peru) - West Fissure (Chile) fault. A 4,500-metre long, northwest-striking panel of strongly magnetic, metasomatized and altered Jurassic-age Guaneros Formation and younger intrusive rocks is host to stockwork and disseminated copper-silver-gold mineralization (oxidized after primary sulphide minerals).These panels are also cut obliquely by narrower silicified and barite-rich vein-like structures mineralized with gold and silver (Cantana). The relationship between the two differing styles of mineralization is not certain. However it is possible that they are both related to a highly evolved, concealed porphyry system at depth.
Exploration is focusing upon the south-eastern 2,200 metres of this mineralized panel where mineralization and alteration is strongest. Here, two areas of copper-bearing basaltic andesite flows, andesitic tuffs and breccias, and diorite intrusive rocks are being mapped and sampled. In this area, Cerro TotoRoko marks a 1,300-metre long by 200-metre wide zone in the northwest, and Lomas Orjo marks a 700-metre long by 400-metre wide zone to the southeast. Both zones show signs of strong shearing, argillic alteration, brecciation and strong fracturing.
New sampling results (chip-channel and grab) from mineralized outcrops at Lomas Orjo include:
-------------------------------- Length Cu % Ag g/t -------------------------------- 5 metres 1.5 9 -------------------------------- 18 metres 0.3 5 -------------------------------- 20 metres 0.2 2 -------------------------------- 23 metres 0.9 9 -------------------------------- 10 metres 0.8 14 -------------------------------- 25 metres 0.7 8 -------------------------------- 10 metres 0.9 12 -------------------------------- 7 metres 2.7 25 -------------------------------- 2 metres 1.9 31 -------------------------------- 2 metres 4.6 50 -------------------------------- 10 metres 3.1 33 -------------------------------- Grab 2.6 21 -------------------------------- Grab 1.9 18 -------------------------------- Grab 6.6 52 -------------------------------- Grab 2.3 26 -------------------------------- Grab 1.1 10 -------------------------------- Grab 1.4 14 -------------------------------- New sampling results of mineralized outcrops at Cerro TotoRoko include: -------------------------------- Length Cu % Ag g/t -------------------------------- 5 metres 3.4 32 -------------------------------- 10 metres 1.2 10 -------------------------------- 4 metres 0.9 21 --------------------------------
Analytical results for copper and silver are rounded-off. Gold is anomalous in both areas, with values ranging from "nil" to 0.4 g/t.
Gitennes has previously reported other sampling results from the TotoRoko area and from areas 300 metres south of Lomas Orjo in a news release dated April 16th, 2007.
The area between Cerro TotoRoko and Lomas Orjo is typically covered by a thick layer of soil and colluvium. Local outcrops show that it is locally strongly altered and fractured, but has not been sampled. A silicified structure, Cantana, was traced for 900 metres north from this area. Preliminary samples taken from the northern 400 metres of this feature returned high silver and anomalous gold values. The quartz-barite vein in this area is 2 to 3 metres wide and deeply oxidized.

Exploration activities continue at TotoRoko with on-going geological mapping and sampling, and ground geophysical surveys (induced polarization and magnetometer) will commence at month's end.
