Metallic screening

Improve knowledge of gold occurrence & distribution within your deposit.

A well-designed screen fire assay program paired with robust geology and resource models can aid in determining the proportion and location of coarse gold within a deposit. Screen fire assay data can provide early indications of process methodology for gold exploration projects, such as an indication of the proportion of gravity recoverable gold present within a deposit, which in turn can impact a project’s economics and potential development timescale.

Gold screen fire assay

Screen fire assays use a larger volume of sample (typically 1kg) which is screened (usually to -75 micron or -106 micron) to separate coarse gold particles from fine material. To aid in distinguishing the proportion of coarse and fine gold within the sample the following results are included in a screen fire assay report:

• The results of duplicate fine fraction assays, plus the mean of the results.
• The coarse fraction gold assay.
• Weights of both the fine and coarse fractions.
• A "total" gold calculation for the 1kg sample based on the weighted average of the coarse and fine fractions.
