Sitasa Energi belum melakukan perhitungan sumberdaya secara&#13;
geostatistik, perhitungan sumberdaya dilakukan menggunakan metoda&#13;
trapezoidal rules. Metode geostatistik (kriging) berfungsi untuk menaksir atau&#13;
mengestimasi kadar rata-rata dari Fe total itu sendiri pada suatu blok yang belum&#13;
diketahui nilai kadarnya baik secara vertikal maupun horizontal sehingga akan&#13;
diperoleh suatu model endapan berupa blok 3 (tiga) dimensi kemudian dihitung&#13;
volume dan tonasenya sehingga akan menghasilkan suatu sumberdaya bijih besi&#13;
berdasarkan persyaratan kualitas yang telah ditetapkan.&#13;
Berdasarkan disribusi kadar pada variogram didapat jarak spasi pemboran&#13;
sebesar 45 meter, sedangkan untuk arah vertikal dilihat dari keseluruhan data&#13;
kadar maka jarak pengambilan conto yang didapat sebesar 13 meter.&#13;
Rata-rata penyebaran kadar high grade berada di ketebalan yang relative tinggi&#13;
yaitu 5-10 meter. Sedangkan untuk rata-rata penyebaran kadar Low grade ada di&#13;
ketebala 2-5 meter. Berdasarkan penelitian yang dilakukan diperoleh penyebaran&#13;
kadar mengelompok pada kadar yang relatif tinggi dengan rata-rata 62.50%.&#13;
diperoleh jumlah suberdaya 5.500.000 ton, denga density 5 ton/m3. Dengan luas&#13;
area estimasi 50 Ha.</mods:abstract><mods:classification authority="lcc">TN Mining engineering.
