    Dear Ian Wollff,

    I have read your CV. and I know that you have experience in Tanjung Enim, South Sumatera as Senior Geologist from 1985 – 1986. I am also have experience worked in Tanjung Enim as Counterpart for Kinhill-Otto Gold Joint Venture, from Departement of Energy for South Sumatera Coal Exploration Project.
    Kinhill-Otto Gold JV also send me to study Geomechanic Laboratory Testing in Coffey & Partners (March 1985 – June 1985).

    Thank you,

    Your Sinceraraly,

    Luhkito Hs.

    • Dear Luhkito_ nice to hear from you. I revisited our old Kinhill-Otto Gold camp site on the side of the hill at Tanjung Enim about 5 years after I left. The trees I planted (palm, acacia) had grown many meters tall and my old room had continued to split and started to slide down the hill. I am thinking its time to visit Tanjung Enim again – to see how much it has changed.

    I had the golden opportunity to work with Ian on Sumatra coal project as a consultant. He is one of the few professionals in the whole my career who left bold and unforgettable memories of superb professionalism as a geologist and specialist in coal mining. Thank you Ian and wish you new professional heights. Best regards, Dr Rossen Halatchev

    • Thank you for the kind words. My local field assistant from Sumatra also worked with me on some Kalimantan projects, and we kept in touch till his passing last year. It seems the old geological camps made close long term friends also. Thanks Ian.

  3. you are very experienced in the field of geology and mining. I want to learn from you about it. recently I’ve been working on gold exploration in Maluku, Indonesia. but I have trouble metasedimen rocks and schist.
    no mineral quartz veins.
