Employee Stories


I have joined PT Ceria Nugraha Indotama since November 27, 2017 as Transhipment Admin, with the responsibility of presenting loading activity report data to the realization of nickel ore sales. The existence of Ceria certainly brings many changes to the local community, both from the social aspect and the community’s economic development aspect. Hopefully, Ceria will complete the construction of the Smelter plant soon and become a world-class and sustainable nickel mining company.
