Marketwired Canada
Eurotin Inc. ("Eurotin" or the "Company") (TSX VENTURE:TIN), is pleased to
provide the following drill results and update on its Oropesa tin project,
located in SW Spain.
Drilling Highlights:
ORPD 128: 16.8m @ 1.09% Sn from 97.0m
ORPD 123: 13.5m @ 0.75% Sn from 191.0m
ORPD 129: 6.5m @ 0.86% Sn from 111.0m
ORPD 142: 25.2m @ 0.85% Sn from 85.7m
ORPD 142: 6.3m @ 1.85% Sn from 200.2m
Other Highlights:
-- The second of the four planned large diameter (PQ) drill holes has now
been completed. These drill cores will shortly be shipped to the
laboratories of SGS Mineral Services UK Ltd in Cornwall, UK for detailed
metallurgical testwork.
-- Sufficient holes have now been drilled to demonstrate good continuity of
the mineralized structures over 1200 metres of the known approx. 2000
metres of tin mineralization at Oropesa.
-- A modest, deep hole, drilling campaign will begin shortly to test for
the presence of additional high grade Primary Structures at depths of
between 250 and 750 metres.

Latest Developments at Oropesa
1. The Company will shortly commence an approx. 10km2 soil geochemistry
survey at Oropesa. The lines will be 250 metres apart and samples will
be taken on 50 metre spacings. Wherever tin anomalies are found, the
area will then be tested on spacings of 25 metres.
2. The Oropesa property is host to several regional geological structures.
Testwork, including drilling, has now commenced to determine which
structures were the conduits for tin mineralization from a deep granite
source.
Conclusion
Peter Miller, President & CEO, comments: "Geological interpretation of our
recent drill results has added further evidence to our belief that the Oropesa
deposit is part of a major new Tin District, probably the first to be discovered
in over 40 years. So while the development of an open pit mine here obviously
remains our first priority in providing value to our shareholders, we are also
keen to determine the district's tin potential."
Assay and QA/QC Methodology for Oropesa Drill Core
All core produced is taken daily from each drill site to the Company's secure
facility in Fuente Obejuna, where it is logged by the Company's geologists. This
process takes place under the supervision of Qualified Person Victor Guerrero
Merino, Euro.Geol.
The core, usually of around one metre length, which is chosen by the Company's
geologists for assaying, is then cut in half either at the Company's own
facilities at Fuente Obejuna or at ALS Chemex's sample preparation facility in
Seville in southern Spain.
At the ALS Chemex facility, the cut core is logged into the in house LIMS
tracking system, after which each sample is prepared using procedure code 'Prep
31'. This procedure involves the drying, weighing and fine crushing to 70%
passing -2mm. A 250g split of the crushed material is then pulverised to greater
than 85% passing 75 microns. Samples are then shipped by bonded courier to
Vancouver for analysis.
In Vancouver, ALS Chemex procedure ME-XRF10 is used for tin analysis and
ME-ICP61 for multi-element (33) analysis. The ME-XRF10 procedure uses 0.9g of
calcined sample pulp, which is mixed with 4.5g of lithium tetraborate and 4.5g
of lithium metaborate. This mixture is then fused at 1,100 degrees C to produce
a flat molten disc, which is subsequently analysed by XRF spectrometry. ALS
Chemex analyses its own standard samples and blanks, plus duplicates, within
each set of samples provided by the Company. The Company has recently introduced
its own blanks and standards as a further means of checking the accuracy of the
assay results. One in every 15 samples analysed by ALS Chemex is then sent to
SGS's laboratories in Cornwall, UK, for check assaying for tin. The Company
keeps all its sample pulps and rejects in locked steel containers at its secure
storage facility in Fuente Obejuna.
The Company recently completed a new check assay program using five certified
laboratories. The pulp sample composites used had varying tin grades; the
accuracy of the results obtained was within acceptable parameters.
Mr. Victor Guerrero Merino, an independent geological consultant and a Qualified
Person pursuant to NI 43-101, has reviewed and approved the technical
information in this news release on behalf of the Company.

estimates; whether mineral resources can be developed; title to mineral
properties; financing requirements, general market conditions, and the
uncertainty of access to additional capital; changes in the world-wide price of
mineral commodities; general economic conditions; and changes in laws, rules and
regulations applicable to the Company. In addition to being subject to a number
