MODEL 3D ENDAPAN Au PADA PIT X PT. MEARES SOPUTAN MINING KABUPATEN MINAHASA UTARA PROVINSI SULAWESI UTARA

Abstract

Gold deposit to be mined should be made a model to calculate the benefit reserves and mine design.The purpose of this study adalan create 3D models Au deposits.To create a 3D model, researchers used data descriptions cutting RCGC (Reverse Circulation Grade Control), the data collar drilling azimuth and dip drilling collar of data, assay data levels and topographical survey data. Intake of drilling samples RCGC do every one meter with drilling spaced 7.5 meters and 12.5 meters of drilling burden.The location carefully situations is an area of Au mineralization is deposited in the fault zone with basaltic andesite host rock.The extent of the area carefully situations ± 2.500m² with a distribution point as much as 30 points drill.Of the 30 drill point is divided into six cross-section, each cross-section consists of 5 drill point.Withdrawal cross-section based on the boundary line color lithology.Red is the color yellow is a waste and ore. This classification is based on the data COG (Cut of Grade) company that is 1ppm. Based on the correlation of cross-sectional shape, generate the model tabular shaped deposits that extends northsouth with dimensions: The mean length of 62.5m, an average width of 30m and an average thickness of 15m.
