Stumbling across your website I recall that my father, Graham Ross Dalitz, was once involved in the Project. He flew a helicopter (Bell - VH UTJ) for Helicopter Utilities P/L at the time, ferrying geologists around. His pilot log book lists that he was there in 1965 from 20 April to 12 August. Places he lists include Kieta, Barapina, Aropa River, Tonalei, Wakunai, Sesivi, Jaba and Paguna Rivers, Torokina, Buin, and Bhoku.
He took many slide photographs over the years, but as yet I have found none which relate to the time, although I know I have seen some.
My father is currently dying of cancer and is really beyond giving us any further information, unfortunately. Just thought you may want to add his name to the list of previous workers up there.
His daughter,
Kind regards,
