Abstract
Determination of Cut-Off Grade in an important component for estimation of deposit reserves calculation. Calculate Simulation are applicated in area X which lateritic nickel deposit, base on sampling data of log bor. The result of simulation are aplication using parameter of moving average grade will be reached reserves more than lowest grade, so for the same production rate will be mined with longer life time. Key Words : Cut-Off Grade, data sampling, lateritic nickel Abstrak Penentuan batas kadar, Cut-Off Grade, merupakan komponen penting dalam estimasi perhitungan cadangan bahan galian. Simulasi perhitungan dilakukan di daerah X yang mengandung nikel laterit, berdasarkan sampling data log bor. Hasil Simulasi menunjukkan bahwa perhitungan cadangan dengan menggunakan parameter kadar rata-rata terendah didapatkan cadangan yang lebih besar dibandingkan dengan menggunakan parameter kadar terendah, sehingga pada tingkat produksi yang sama didapat umur tambang lebih lama. Kata kunci : Cut-Off Grade, sampling data, nikel laterit
