Using multiple-point geostatistics for geomodeling of a vein-type gold deposit

Mining

This technical paper explores the use of multiple-point geostatistics for modeling narrow, long-range vein-type gold deposits where limited drill-hole data makes conventional two-point geostatistical methods difficult to apply....
