TORONTO, ONTARIO--(Marketwire - Feb. 20, 2013) - Eurotin Inc. ("Eurotin" or the "Company") (TSX VENTURE:TIN), is pleased to provide the following update for its Oropesa tin project located in southern Spain, which includes an important new geological interpretation of its mineralized zones. The new interpretation was developed subsequent to the Company's first mineral resource estimate (prepared in accordance with National Instrument 43-101) discussed below.
The 2011/2012 Oropesa Drill Program
By the end of 2012, the Company had completed Phase 1 of its drill program of 211 core holes at Oropesa, totalling 45,466 metres. A summary of the drill results is shown below:
Phase 1: Averages of All Drill Intercepts - See Appendix for Full Details*
| Cutoff Grade | No. of Intercepts |
Av. Thickness (m) |
Total Length (m) |
Av. Tin Grade (%) |
|
| 0.20% Sn | 229 | 11.2 | 2,553.4 | 0.59 | % |
| 0.35% Sn | 191 | 5.9 | 1,016.3 | 0.97 | % |
| 0.50% Sn | 192 | 4.5 | 866.0 | 1.17 | % |
| * The above results exclude 5 holes which were drilled NNE 'down structure', including ORPC 2, which reported an intercept of 106.1m @ 1.73% Sn. |
Approximately 95% of the above intercepts occurred at vertical depths of less than 180 metres and represent tin mineralization that can potentially be mined through the use of low cost, open pit methods.
The Company reported its first resource on October 9, 2012 (the "2012 Resource Estimate"), as shown below:

Oropesa's Tin Deposits
In its October 9, 2012 press release, the Company revealed that it had not been possible to demonstrate continuity of mineralization between many of the high grade intercepts at Oropesa and therefore they had to be treated as isolated intercepts, which made a negligible contribution to both the tonnage and the tin content in the 2012 Resource Estimate.
A re-assessment of the geology at Oropesa was undertaken during the final quarter of 2012, which resulted in the following conclusions:
- Oropesa's style of tin mineralization is probably unique.
- The tin mineralization at Oropesa is typically found in recumbent folds - see Schematic 1.
To view Schematic 1 - Oropesa: Line 3 Cross Section, please visit the following link: http://media3.marketwire.com/docs/854432fig1.pdf.
- The best tin mineralization at Oropesa is usually found as large, crescent shaped structures at the closed end of the recumbent folds - See Schematic 2.
To view Schematic 2 - Oropesa: Cross Section Through a Typical Mineralized Structure, please visit the following link: http://media3.marketwire.com/docs/854432fig2.pdf.
- The tin mineralization so far found is almost exclusively hosted in the transition zone between coarse, feldspar rich, quartzites and pebble conglomerates.
- Tin mineralization is sometimes found in multiple, cross cutting (anastomosing) structures.
- The 1,500 metre long, WNW/ESE trending, zone of mineralization is cut by modest N/S faults, approximately once every 150-200 metres.
Tin mineralization, other than in metallurgically complex skarns, is typically found following a fault, or fracture system, down to its original granite tin source. As the schematics demonstrate, Oropesa's unusual mineralization zones are found in large, intensely folded, structures. These zones may represent part of a stacked sequence of structures continuing down to a hidden granite located at depth.
Not surprisingly, problems were often encountered in demonstrating continuity of high grade mineralization in the wireframe model used for the 2012 Resource Estimate. This was mainly due to: i) relatively wide drill spacings, ii) the irregular crescent shape of the mineralization, and iii) difficulties in interpreting the continuation of the tin bearing structures across oblique N/S faults.
Demonstrating continuity of mineralization is an essential pre-requisite for an accurate resource calculation. Based on the new interpretation, a new wireframe model is now close to completion, which demonstrates better continuity of the high grade drill intercepts, and has formed the basis for a proposed 30 hole infill drilling program.
2013's Exploration Targets
In addition to the comprehensive infill drilling program designed for 2013, the Company is also planning the following:
- A modest drill program to test for the eastern and western extensions of the known tin deposits at Oropesa.
- An as yet undetermined number of drill holes to test the tin anomalies encountered in the recently completed 6.75km2 (542 samples) soil sampling program.
- Three deep (+300 metres) holes to test for the presence of stacked deposits of 'Oropesa-style' tin mineralization at depth.
- Anomalous tin values have been located in stream sediment sampling over an area exceeding 25km2 around Oropesa. The Company intends follow up soil sampling programs in areas of potential tin promise.
Conclusion
Peter Miller, Eurotin's President & CEO comments: "The results of the successful 2011/12 drill program are shown below and clearly demonstrate the Oropesa district hosts a major tin mineralization event. Now that we understand its geology, a major and significant milestone has been achieved in our plans to develop a major, open pit, mining operation by mid-2016. The next step, planned for third quarter 2013, will be to prepare a new resource estimate, which should more accurately reflect Oropesa's unusual geological structures."

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°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.
