On top of that, leachwell tests indicated a higher average grade than the common fire assay test. This is because of the nature of the lateritic deposit, which contains coarse gold, resulting in a nugget effect. The 50g fire assays obviously only partially take this nugget effect into account, and that''s why leachwell tests are more accurate.

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.
