The late Paul Coleman was with the company for 19 years and played a major role in the restoration of dialogue between the Autonomous Bougainville Government and the B-C-L.
He's been described by the B-C-L Board as a great friend, who was committed to a range of community and philanthropic activities in P-N-G.
In 2014, Coleman was made an officer in the Order of the British Empire for his service to commerce, the mining sector and charities.
The B-C-L Board has passed its condolences to his wife Kym and family.
His funeral will be held at the Cathedral of Saint Stephen in Brisbane, Australia, on Friday.
