July 16 (Reuters) - Santacruz Silver Mining ( SZSMF ) said

on Tuesday that an employee at the Tres Amigos mine in Bolivia

died after a small group of illegal miners unlawfully entered

the mine and used explosives.

The explosives were used at the level above the one where

company's employees were working and caused rockfall on them

below, Santacruz said in a statement.

Santacruz has launched an investigation and added it will

consider taking legal action against those responsible, once the

investigation is complete.

Tres Amigos mine, a part of the Caballo Blanco Group of

mines, has resumed operations after it was shut down following

the incident.
