DAKAR, May 20 (Reuters) - Ivanhoe Mines ( IVPAF ) has

suspended some mining operations at its Kakula underground

copper mine in the Democratic Republic of Congo after seismic

activity, it said on Tuesday.

The Canadian miner halted underground operations on Sunday

after a week of tremors. The company said that all employees

working underground were safely evacuated and the western

section of the mine was declared safe to resume operations.

The mine's two concentrators are operating at reduced

capacity, processing stockpiled ore. The adjacent Kamoa mine has

not been disrupted, Ivanhoe said.

The company is ramping up copper mining at the Kamoa-Kakula

complex. In Congo Ivanhoe also operates the Kipushi zinc-copper

mine.
