Bulk leach extractable gold
Bulk leach extractable gold (BLEG) was developed in the 1980s to reduce the impact of nuggety gold. Today, it can be used in exploration for trace gold determinations to provide robust, consistent results. The large sample size utilised can help decrease the influence of coarse gold making results more reproducible.
