This followed a 7.5 magnitude earthquake that struck the area on Monday, 26 February.
BNL executive managing director, Richmond Fenn, said the earthquake epicentre was located approximately 90km South West of the Porgera mine, close to the mine’s power generation plant at Hides.
“While the mine itself appears to have been unaffected by the quake, our primary power generating facility located some distance away in Hides has sustained damage, and is now offline,” Fenn said.
