The SRK report has been prepared in accordance with National Instrument 43-101. The PEA is considered preliminary in nature. It includes inferred mineral resources that are considered too speculative to have the economic considerations applied that would enable classification as mineral reserves. There is no certainty that the conclusions within the PEA will be realized. Mineral resources that are not mineral reserves do not have demonstrated economic viability.
SRK has used two tin price profiles, one of $23,250/t and one of $27,000/t, both of which produced potentially economic results, with pre-tax IRRs respectively of 14.3% and 24.4%. In SRK’s opinion, given the expected tin deficit, a tin price of $27,000/t from 2016 onwards is a reasonable scenario to assume, which provided the following financial analysis:

The principal parameters for the Oropesa Project were as follows:
Mining & Processing Operating & Capital Costs (US$)

The currently envisaged Oropesa operation is expected to produce approximately 26,000 tonnes of tin metal from 8.6 million tonnes of mineralised material.
The Oropesa open pit mine plan was derived from the following resource, which was previously released by Eurotin on June 10, 2014:

(3) The Mineral Resource Estimate for the Oropesa deposit was constrained
within grade based solids and above a relative elevation of -200m.
(4) Mineral Resources for the Oropesa deposit have been classified according
to the “CIM Standards on Mineral Resources and Reserves: Definitions and
Guidelines (December 2005)” by Howard Baker (MAusIMM(CP)), an
independent Qualified Person as defined in NI 43-101.

SRK commented that in addition to the potential for new resources at depth and to the east within the known mineralised structures, the potential for mineralisation in near vertical feeder systems should be investigated further.
Metallurgy and Processing
SRK reviewed the metallurgical work undertaken by SGS Mineral Services UK Ltd (“SGS”) to date and concluded the following:
1. The mineralised material contains sulphides, which have to be removed
prior to tin recovery.
2. The principal tin mineral is cassiterite (SnO2). Approximately 4% of the
cassiterite is expected to be too fine grained to recover.
3. The unrecoverable tin sulphide mineral stannite (Cu2FeSnS4) is present
in amounts generally varying between 7% and 9% throughout the deposit.
4. Approximately 35% of the cassiterite is recoverable by conventional
gravity techniques and 80-90% of the remaining cassiterite is
recoverable by conventional flotation.
5. Both gravity and flotation concentrates will have an approximate grade
of 55% tin.
6. At the 0.41% Sn average grade anticipated for the Oropesa open pit, SRK
believes an approximate average tin recovery of 74.5% will be attained.
7. The capital cost of the processing plant is expected to be $55 million.
1. Mining is by open pit to a maximum depth of 200 metres limited by the
depth of the current drilling.
2. On completion of mining, the planned pit will be 1,350 metres long, 400
metres across at its widest point and 200 metres deep.
3. The PEA does not include any potential high grade mill feed from
4. A geotechnical investigation by SRK resulted in an average pit slope of
52 degrees and a life of mine waste: ore stripping ratio of 5.3:1.0.
5. For close grade control, the pit will be mined on 4 metre benches using
conventional truck and shovel techniques.
1. Oropesa is located in an area of southern Spain with a long history of
2. Local farming activity is mostly at a subsistence level with the
principal activity being the fattening up of black pigs during the
winter months using acorns from evergreen oak trees, which are found
throughout much of the Oropesa property.
3. There are no significant river systems near to Oropesa and the open pit
is not expected to be impacted by groundwater.
4. A full description of the environmental action required, plus the
permits needed, for a mining operation in the Region of Andalucia can be
found on pages 147-153 in the PEA.
Infrastructure and Other
1. Major power lines and commercial dams are located less than 8 km from
Oropesa. In addition, sufficient power and water supplies can be
obtained from the town of Penarroya, some 14km to the east of the
2. Oropesa is located approximately 3 km from a well maintained tarred
road, which provides direct access to the cities of Cordoba and Seville.
3. The Oropesa deposit is screened from nearby villages by two lines of
hills, the Sierra de Las Cabras and the Sierra La Grana.
4. There is a large skilled workforce locally available.
5. The long history of nearby mining is expected to be a beneficial factor
in the development of the Oropesa project.
Summary and Conclusion
David Danziger, interim CEO of Eurotin comments, “It is no secret in the mining industry that the tin supply deficit is likely to grow significantly in the near future, which makes our project ideally placed to take advantage of what we anticipate will be a prolonged period of elevated tin prices. This PEA is a major step forward for us in the commercial development of the Oropesa project. In addition, the limited drilling below 200 metres has meant the good drill intersections made there could not be included in either the resource or the PEA’s open pit design. These intersections convince us that Oropesa’s real future lies at depth beneath the 200 metre deep open pit used in the PEA.”
The complete technical report constituting the PEA will be filed within 45 days and will be available on SEDAR.
