AMS Resource Statement for the FCR Toral Zn-Pb Project
The block model currently extends for a strike length of 3,300m and is still open to the east along strike and also at depth where it has not yet been closed off.
Rubiales MineFrom 1976-92, mined 12 million tonnes of ore and produced around 1.4 million tonnes of high grade (61% Zn) zinc concentrate and over 213,000 tonnes of high grade (70% Pb and 500g/t Ag) lead concentrate
Antonina MineMined between 1935-83, still with ore in situ
Las Medulas MineMined by the Romans for nearly 200 years, producing over 200 tonnes of alluvial gold. (74 AD, Mining Procurator reports on extraction and recovery - Pliny)
