Oceana Gold's copper and gold mine on the northern Philippines island of Luzon was left unscathed by typhoon Koppu, which has been downgraded to a tropical storm, but not before taking at least 47 lives.
Since it made landfall in the northern Philippines on Sunday morning, torrential rain has inundated mountain villages for days, and the death toll is expected to rise.
Despite the downgrade on Monday, rain is expected to continue pummelling some areas across the northern Luzon region.
The BBC reported the Philippine Government was warning citizens the deadly impact of typhoon Koppu would persist for several days, and warned some of the tens of thousands of displaced people not to return home yet.
Construction of Oceana's open pit Didipio mine began in June 2011 and by April 2013 it began producing copper and gold.
A spokeswoman for Oceana said yesterday that the Didipio mine was ''out of typhoon alert'' and that all employees were safe and the mine was operating as normal.
''The surrounding communities received minimal damage and our team in the Philippines is now assisting the local governments where it can,'' the spokeswoman said, when contacted yesterday.
Meteorologists had reported the centre of the tropical storm was now just north of mainland Luzon, which put the northern regions of that island, Ilocos, Cagayan Valley and the Cordillera at risk of additional heavy rainfall yesterday, by as much as an additional 200mm.
