The Met-Solve Bulk Gravity Assay (MBGA) is an industry standard service that combines the metallurgical experience of Met-Solve Laboratories with the assay capabilities of Met-Solve Analytical.

Sampling and analysis during exploration is a key component to the success of all potential mining companies. However, for some deposits standard assay protocols have a tendency to underestimate grades.

Gold in particular can be subject to the “nugget effect”, in which the gold is heterogeneously distributed in the form of discrete particles.

The MBGA uses centrifugal gravity concentration to collect free gold within a sample that is 160 times larger than a standard assay. This produces a single concentrate that can be assayed to extinction. 

Combined with multiple assays of the tails, this quick testing method allows for a calculated head grade that more accurately represents the true deposit grade.

By standardizing the metallurgical process, Met-Solve can process a large number of samples while offering attractive pricing that is a fraction of the cost of standard metallurgical testing programs.
