Abstract
Klasifikasi sumberdaya mineral ialah suatu hal yang sangat penting dalam bidang eksplorasi terutama dalam penaksiran cadangan. Penelitian ini dilakukan pada endapan Nikel laterit Pulau Obi dengan pemodelan geometri endapan bijih nikel laterit dan kemudian dilakukan klasifikasi sumberdaya yang mengacu pada standar klasifikasi sumberdaya mineral dari SNI 4726:2011 dengan pendekatan RKSD berdasarkan data estimasi Ordinary Kriging. Hasil Klasfikasi Sumberdaya, jumlah Total sumberdaya tonase dan kadar rata-rata yaitu sumberdaya measured (Terukur) 414.016 ton Ni 1.69% Fe 23.34%, indicated (Terunjuk) 1.318.375 ton Ni 1.23 Fe 36.16 dan jumlah sumberdaya Inferred (Tereka) 98.672 ton Ni 1.01% Fe 44.73%.
