The highest tin grades are found in five distinct mineralised zones along a 1,500 metre long, continually mineralized structure. A further three new mineralized zones were found subsequent to the 2012 Resource Estimate; evidence for these three new zones is provided by the discovery drill intercepts 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:
1. Oropesa's style of tin mineralization is probably unique.2. The tin mineralization at Oropesa is typically found in recumbent folds - see Schematic 1.

3. 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.

4. The tin mineralization so far found is almost exclusively hosted in the transition zone between coarse, feldspar rich, quartzites and pebble conglomerates.5. Tin mineralization is sometimes found in multiple, cross cutting (anastomosing) structures.6. The 1,500 metre long, WNW/ESE trending, zone of mineralization is cut by modest N/S faults, approximately once every 150-200 metres.
