GITENNES TOTOROKO PROPERTY � NEW
RESULTS POINT TO ADDITIONAL DRILLING
Vancouver, April 1,
2008: Gitennes Exploration Inc. (TSX-GIT) is pleased to advise that a
detailed report on its 100%-owned TotoRoko Property has been filed on SEDAR. The
report, title �TECHNICAL REPORT on the TOTOROKO PROJECT, Department of Arequipa,
Per�� was authored by Alvaro Fern�ndez-Baca, P.Geo. and James R. Foster, P.Geo.,
two experienced geologists in the employ of Gitennes.
Included within the report are the
results of a multi-element Mobile Metal Ion (�MMI�) survey completed over the
area of the Canta�a structure and the �Northern IP Anomaly�. In December 2007
Gitennes drilled one core hole on the Canta�a structure, aimed to test some
high-grade silver and gold results obtained from surface rock-chip sampling. The
hole encountered a wider-than-expected zone of argillic-altered, strongly
oxidised breccia that began at a down-hole depth of 28.50 metres. The main
Canta�a quartz structure was hit at a depth of 48.55 metres and continued, with
varying degrees of fracturing and brecciation, down to 99 metres (50.45 metres
of core length, or 35.7 metres true width). This deeper quartz-rich structure is
accompanied by moderate sericite alteration and locally heavy pyrite with minor
local chalcopyrite and other unidentified fine-grained metallic minerals. The
Canta�a structure contains evidence of multiple brecciation events evidenced by
cemented brecciated quartz clasts, such that it must have been the focus of
several hydrothermal pulses or repeated fault movements, or
both.
Despite the attractive-looking core,
the rocks returned low grades with the highest assay results coming from a
1.45-metre sample of vein material, with 0.75 g/t Au and 8.9 g/t Ag. Pyrite and
galena occur as minor minerals in this interval. All other samples taken from
the vein and from the fault zone yielded less than 60 ppb gold and less than 4.9
g/t silver. Copper numbers of up to 0.2 % copper are coincident with traces of
fine-grained sulphide minerals, as is zinc (up to 0.26% Zn) and lead (up to
0.19% Pb).
The Canta�a hole did not test the
Northern IP anomaly. Due to the poor development of soils in the area, the
presence of transported colluvium, and the dry desert-like conditions that
characterize the climate for most of the year, MMI was thought to be a more
effective soil geochemical technique than conventional soil sampling. MMI is a
technique pioneered in Australia that targets metals that are weakly bonded onto
the outer surfaces of soil, gravel and sand. The �soil samples� are not sieved
and analysed by conventional destructive processes, instead weak reagents are
used to take these surface ions into solution, which can then be analysed
..
A total of 182 MMI samples were
collected by Gitennes geologists in January 2008 along eight survey lines
oblique to stratigraphy but crossing the Canta�a structure. The aim of the survey was to identify
possible deep-sourced geochemical anomalies over the northern IP anomaly that
may not have been picked up by conventional soil geochemistry methods. A test
line parallel to the Lomas Orcco zone was completed in order to see the strength
of an MMI response associated to mineralization in this area (TR07-07 which
intersected 0.75% copper over a core length of 29.65 metres, including 5.35
metres at 3.90% copper).
Results show very strongly anomalous
copper (up to 28,400 ppb), silver (up to 2,120 ppb), gold (up to 56.3 ppb) and
lead (up to 37,100 ppb) values associated to the Canta�a structure and to
another north-south trending structure to the east, with copper responses
similar to those obtained on the Lomas Orcco test line. Sampling of outcrops in
this area revealed no significant copper values, and only minor copper was
encountered in drill hole TR07-01. It is possible that the MMI method may be
outlining a deep copper target. The eastern MMI copper anomaly is unexplained
and is not associated to any surface copper mineralization, but is centered upon
another north-trending lineament.
The writers of the Technical Report
note that the exploration done in 2006 focussed primarily on bedding-parallel
copper zones. Second priority targets were the structurally-controlled north
trending Canta�a and Lomas Orcco zones. The results from TR07-01 and TR07-07,
coupled with follow-up exploration such as the MMI survey, show that these
north-trending structures are equal to, or perhaps of greater exploration
significance, than the original primary target. They also noted that the 2007
geophysical survey was not optimally oriented (north-northeast) or spaced (at
200 metres apart) for these north-trending structures, with only three lines
obliquely crossing either the Canta�a or the Lomas Orcco structures. Closer
spaced lines oriented east-west are more suitable to test these targets.
Fern�ndez-Baca and Foster recommend
that future exploration at TotoRoko includes:
1. Additional IP surveys are done on
east-west survey lines over the north part of the Canta�a structure and adjacent
anomalous areas eastwards to the Lomas Orcco structure.
2. Expansion of the detailed mapping
area and additional petrographic studies of the alteration
zones.
3. Completing drill hole TR07-07 to
its target depth. Follow-up drill holes should also be completed in step-outs
towards the south of TR07-07 along the north-south structure defining the
mineralization.
4. Drilling three deep holes near the
Canta�a structure to test the MMI and the coincident chargeability anomaly.
5. Drilling two shallow holes in the
untested Jala Orcco zone.
Gitennes is pleased by the results
of the MMI programme at TotoRoko. Representatives of the Company are currently
re-visiting communities in the project area to explain our near-term plans,
which will include following the recommended exploration
programmes.
Exploration at TotoRoko has been
under the supervision of Alvaro Fernandez-Baca, P.Geo. and James Foster, P.Geo.
