LOMERO POYATOS

The Lomero-Poyatos deposit is located in the north-east part of the Spanish/Portuguese (Iberian) pyrite belt which extends about 230 km between Seville in the east (in southern

Pyrite is the predominant sulphide, but the sulphide minerals of greatest economic importance are sphalerite, chalcopyrite, tetrahedrite and galena. The massive sulphide and semi-massive sulphide zones at Lomero-Poyatos are significantly enriched in gold. In terms of gold content, the Lomero-Poyatos deposit has the highest gold grades in the IPB with values of 2.0 m at 14.1 g/t Au and 0.55 m at 16.84 g/t Au being returned from CMR/Newmont drill holes in 2007. There is copper-enrichment in the central part of the mine, with some zinc-lead-gold enrichment towards the eastern and western margins of the deposit. Spain) and the Atlantic coast near Lisbon in the west (in Portugal). The Lomero-Poyatos deposit is located on the northern margin of the pyrite belt.

The Iberian Pyrite Belt is the largest concentration of massive sulphides in the world.
