Semirara, a unit of Philippine conglomerate DMCI Holdings Inc, was forced to halt coal exports following a suspension imposed from July 17 after a landslide at Semirara’s Panian mine in central Philippines buried nine workers alive.

In a Sept. 17 letter to Semirara President Victor Consunji, a copy of which accompanied the firm’s disclosure to Manila’s stock exchange, Department of Energy OIC-Secretary Zenaida Monsada said Semirara has "substantially complied with the conditions…resulting in a marked improvement in the level of safety in its mining operations."
