Placer Dome stepped forward in a time of crisis to prevent an accident from worsening and remained to fulfill its voluntary commitments, even after divesting of its minority shareholding. As a responsible corporate citizen, Placer Dome caused its Philippine subsidiary [Placer Dome Technical Services (PDTS)], to contain the problem, remediate the effects of the accident, compensate those affected, and work diligently to be a positive presence on the island of Marinduque in the absence of any other party willing or able to conduct the necessary work.
