Assess the material.
Clarify the basis.
Prepare minerals, ores and concentrates enquiries around material identity, assay information, physical condition and the intended processing requirement.

Start with the assay and commercial basis.
A minerals or concentrates enquiry should identify the material and the composition relevant to its intended use. Share the available assay, the sampling basis and the quantity under discussion.
Specify whether figures are expressed on a dry or wet basis and identify moisture requirements. Impurities, particle size and physical condition may also be relevant to evaluation.
Origin, location, inspection arrangements and commercial availability require material-specific confirmation. Our specialist materials imagery represents the wider catalogue and is not a photograph of a mineral lot.
