Xtierra Reports High Grade Silver Intercepts in Drilling Immediately South of the Bilbao Deposit

27/06/2011 5:42pm

Marketwired Canada


Xtierra Inc. (TSX VENTURE:XAG) ("Xtierra" or the "Company"), is pleased to
report the completion of a program of eight diamond drill-holes, totalling 2,648
metres, in the southern part of the Bilbao project, Zacatecas, Mexico. The
programme investigated two types of silver-rich targets located immediately to
the south of the main polymetallic Bilbao deposit upon which Xtierra is
completing a feasibility study. The targets, all with high grade silver content,
comprised high angle hydrothermal veins and brecciated limestone horizons. Two
Holes (X-86C and X93)-tested geophysical anomalies (magnetic) located 50-70
metres further to the south.


Six separate mineralized veins and/or fault-fillings were identified. Four of
the mineralized fault structures trend NNW-SSE while another two veins strike
NNE-SSW; the former have strong base-metal values while the later contain silver
values of up to 664g/t silver and have been traced over a strike length of at
least 70m and remain open-ended. 


The holes were targeted to assist in determining the characteristics and
continuity of the high grade silver veins previously found in drill-hole X26 at
the southern margin of, and beneath, the main Bilbao deposit. The width of these
structures varies, with veins averaging about 1m true thickness and
fault-fillings up to 12m in thickness. The veins, which are comprised of
amethystine quartz with calcite, are closely related with the contact of the
limestone horizons with the main La Blanca granitic batholith. 


The NNW-SSE structures typically contain higher base-metal values with combined
zinc and lead values of 14.95% (4.85% lead and 10.10% zinc) including 0.31%
copper and 97.9g/t silver over 4.65m in DDH X86-B, 21.39% combined zinc and lead
(9.96% lead and 11.43% zinc) including 0.27% copper and 127.6g/t silver over
1.05m in DDH X86A, and in DDH X86B-1 there is an intersection of 12.10m with
average grades of 9.08% combined zinc and lead (4.17% lead, 4.91% zinc)
including 0.63% copper and 109.4g/t silver. Several other narrower intersections
have been recorded. Not all analyses have been received and these will be
reported when available. 


The three-dimensional morphology of the silver veins is not yet fully
understood. Although the intersections are high angle intercepts, insufficient
drilling has been completed on each vein structure to permit the precise
calculation of true width. The table appended below indicates intersected width
which is likely to be within 15% of true width.


Drilling has shown that the richer silver veins trend NNE-SSW, a direction which
accords with similar vein trends to the north of the Bilbao deposit, within the
La Blanca granite. Discovery of this zone of silver-rich veins beneath and in
addition to the main skarn-replacement zinc-silver-lead-copper mineral deposit
at Bilbao is expected to contribute to both tonnage and silver content of the
resource. However, additional drilling will be required before any new resource
estimate can be made.


Commenting on the preliminary drill results on the high grade silver zone,
Xtierra's CEO, Terence McKillen, said "The recognition of rich silver-bearing
vein structures at the Bilbao project is very encouraging and opens up the
potential for identifying additional resources, to the south of the main Bilbao
deposit. The existence of NNE-SSW striking vein structures containing grades of
over half a kilogram per tonne silver is a particularly exciting development.
This exploratory drilling program has been conducted as part of a Feasibility
Study pertaining to all aspects of the Bilbao project which is currently being
undertaken under the independent supervision of DRA Americas."


Analytical Method 

Samples from half-core were prepared at the Stewart Group laboratory in
Zacatecas and initially analyzed for 38 element content using ICP-MS
(inductively coupled plasma - mass spectrometry) by the Stewart Group (Eco-Tech
Laboratory) in Kamloops, British Columbia. Values exceeding the limits of
detection are automatically re-analyzed by Fire Assay or Atomic absorption
spectrometry (AAS) methods respectively. Standards and blanks were used
regularly for quality control.
