Iska Iska Caldera Complex

Iska Iska was never discovered by historic prospecting due to surface leaching that removed all sulphide metals.

Historically a key supplier of tin to the USA, Bolivia continues to play a major role in global tin markets. The country has major opportunities in deeper porphyry-style tin systems and polymetallic deposits.
